A coke oven battery bench cleaning apparatus comprises inner disk brush (1), rolling brush (2) and outer disk brush (3). The apparatus is linked to a steel frame through a rigid support. The inner disk brush (1) and the outer disk brush (3) are separately arranged at the two sides of the steel frame. The rotation axes of the inner disk brush (1) and the outer disk brush (3) rotate around a plane perpendicular to the coke oven battery bench. The rotation axis of the rolling brush (2) rotates around a plane parallel to the coke oven battery bench. Comparing with the prior art, (1) the coke oven battery bench cleaning apparatus eliminates the need for a worker to clean the bench where he is exposed to adverse environmental conditions while ensures the coke-holding-back machine working, for the design of the apparatus is more humanizing and convenient for use; (2) the automatic level of equipments is increased as the cleaning apparatus being provided as an assistant equipment; (3) the design of the apparatus is environmental friendly as the residual cokes and coarse particles at the corner of the bottoms of the coke oven body and the track can be cleaned with the apparatus.
A double girder and multi hanging point crane comprises main girders, a lifting mechanism, a translating mechanism (4) and an electric control system, characterized in that said main girders are double main girders (1,2) highly and lowly arranged, each main girder having variable sections and being high and narrow compound girders composed of three-box-typed main girders; the lifting mechanism is composed of multi sets of hoisting systems (3), each set of hoisting systems (3) respectively connected to and controlling multi hanging points and synchronously driving above all hanging points through the electric control system; a rope arranging mechanism is arranged at the hoisting systems (3), and a mono-connecting and multiplayer twisting rope system is adopted; the translating mechanism (4) is main girder bidirectionally self-translating mechanism arranged at the two ends of the lower main girder; the electric control system is an electric control system of multi hanging point crane hyperstatic system.
A wire rope space anti-interference arrangement for a crane with multiple hoisting points is disclosed. The hoister comprises a main girder (10), a movable pulley block (3), a fixed pulley block (5) and a hoister (1). Leading pulleys (2) are provided in the upper space of the upper cover board of the main girder (10). Hoister steadiers (7) with different height are provided at two ends of the cover board. Corresponding to the height of the hoister steadiers (7), the leading pulleys (2) are mounted at different height. Connecting lines are located between the vertical center lines of the hoister winding drums provided at two ends of the main girder (10) and the center lines of the respectively corresponding leading pulleys (2) of the hoister winding drums. A same small fleet anger (&agr;) is formed between the connecting lines and the center line of the main girder (10), corresponding to the fleet anger between the hoister (1) at the same end and the main girder (10). The two fleet angers between the hoisters (1) at two ends and the main girder (10) are opposite. The anti-interference arrangement is simple, its manufacture, installation and maintain is handy, its operation is of highperformance, safe and reliable. The arrangement is applied to the crane for hoisting the superheavy article such as drilling platform and so on.
An electric control method and its equipment for crane with multiple hoisted points, the control method includes as follows steps: a. ready mode, for detecting whether the high and low voltage power distribution system, main drive system, control system, etc, have failure or not; b. rope pre-tensioning mode, where every rising motor adopts torque control, offers torque given value, and makes sure if the rope is tensioned or not by the weighing sensor; c. suspending stop mode, every rising motor adopts speed control, the controller sets motor torque amplitude limiting value, performs loading sling, works out the centroid place of sling object; d. associated hoisting mode, every rising electromotor adopts speed control, the torque amplitude limiting of motor is the same as the suspending stop mode, ever and again monitoring and amends to keep the sling object balanced hoisting. The electric control means improves automatic control level, task efficiency, reduces misplay of manual work. The technique can be used in various synchronization control cranes.
A car tipper overturn cushioning device comprises buffer I (1), buffer II (2), the two are respectively fixed on outside of rotor end ring (4), wherein it also comprises middle swing link (5) and buffer III (3), inside end of middle swing link (5) is hinged on end ring (4), buffer III (3) which is fixed on end ring (4) and buffer I (1) are separately set on two sides of outside end of middle swing link (5).

The utility model relates to a coke discharging apparatus of coke oven, especially a coke pusher of a horizontal carbonization chamber. The two-end coke chute collecting apparatus includes a driving mechanism, a repairing operation platform, a coke hopper, a guard board, a slide chute and a safeguard rail. The slide chute and the repairing operation platform are fixed together. The driving mechanism is mounted on the repairing operation platform. The slide chute is moved back and forth by the driving mechanism. The guard board is on the top of the slide chute and the hopper is at the bottom of the slide chute. When the slide chute moves forward, it passes through the safeguard rail and gets to the place where the two-end coke located. When the slide chute moves backward, the two-end coke will be scraped to the hopper by the guard board. There is an exit at the bottom of the hopper. The exit is opened regularly by a hydraulic system and the two-end coke is dropped into a collector. The apparatus allows a safeguard rail fitted on the machine side. Therefore the operation is complied with the security act and the need for safety production is satisfied. At the same time, the two-end coke is disposed and facility abrasion is decreased.
The utility model relates to a feed charging and discharging apparatus of coke oven, especially relates to a dust removing coke guide vehicle used in horizontal carbonization chamber. The coke guide vehicle includes steel framework, running mechanism, coke guide device, door cleaning device and two-ends coke disposal apparatus, characterized in that a door lifting and door jamb cleaning apparatus is mounted on the steel framework. The said door lifting and door jamb cleaning apparatus comprise coke oven door lifting device and coke oven door jamb cleaning device and rotation device, wherein the door lifting device and the door jamb cleaning device are arranged on said framework at an angle of 90°. On the steel framework above the coke guide device and near the coke oven side there is a moving framework of smoke collection on cokery mouth. Adding a moving framework of smoke collection on cokery mouth can realize simultaneous collection of smoke from coke at cokery mouth and coke separated from the oven, which can obtain a good dust removing effect. Integrating the door lifting device and the door jamb cleaning device together provides compact structure for the coke guide vehicle. It helps to finish the operation of the carbonization chamber with one hole at two positions, and saves operation time. Two-ends coke disposal apparatus can automatically dispose the end coke generated from coke guide, door cleaning and door jamb cleaning, which can reduce the manpower.
