Abstract

Disclosed in the present invention is a guide rail lifting device, for use in upwards lifting a guide rail to be mounted along a mounted guide rail. A guide rail to be lifted and the mounted guide rail both are provided with a bottom and a guide part that are perpendicular to each other; the guide part has two opposite side surfaces and a top surface away from the bottom. The guide rail lifting device comprises a lifting plate used for being fixed to the bottom of the guide rail to be lifted, and a side surface roller assembly and a top surface roller assembly that are provided on the lifting plate; and the side surface roller assembly and the top surface roller assembly are fixed to the lifting plate by means of a connecting arm assembly. According to the guide rail lifting device of the present invention, the guide rail lifting device slides on a side surface of the guide part of the mounted guide rail so as to drive the guide rail to be lifted to slide, and therefore, a safe lifting path can be provided for the guide rail to be lifted in a guide rail hoisting process, the guide rail is protected against damage caused by collision in a lifting process, mounting and dismounting are convenient, and repeated use can be achieved.

Abstract

A step driving apparatus for a spiral escalator, comprising a main drive shaft (17), step chainwheels fixed on either end of the main drive shaft and a drive motor (18) used to drive the step chain to rotate. The step chainwheels comprise a first step chainwheel (21) and a second step chainwheel (22). Step axles (6) are arranged on steps (3). The diameter of the first step chainwheel is greater than the diameter of the second step chainwheel. The main drive shaft is arranged horizontally, and the step axles are arranged to form an angle with the main drive shaft. The step driving apparatus for a spiral escalator features a structure of simple design, and the initial power for two step chains originates from the same main drive shaft, allowing the two to start and stop synchronously, ensuring escalator riding safety. By means of adjusting the size of the pitch diameters of the step chainwheels, different movement speeds of the inner ring and outer ring of the spiral are achieved, and the structure is simple and easily implemented. Arranging the main drive shaft horizontally is a mature technique and is safe in use.

Abstract

A step structure for a spiral escalator, comprising a plurality of steps (3), step axles (6) arranged on the steps, and a step chain used to drive the step axles. A step comprises a tread (8), a riser (9), and an inner end plate (151) and an outer end plate (152). The step chain comprises an inner ring step chain (4) and an outer ring step chain (5). The tread of a step is of an annular sector shape, and the radius corresponding to the inner ring of the tread is smaller than the radius corresponding to the outer ring of the tread. A step axle is provided with an inner end part and an outer end part, and the distance between inner end parts of adjacent step axles is less than the distance between outer end parts of adjacent step axles. The step structure for a spiral escalator causes, when a step rotates, the distance traveled by the outer ring to be longer than that of the inner ring, and cooperates with the annular sector-shaped step tread, causing either side of the steps to have different movement speeds. The difference in speeds is used to cause the steps to turn to the side when advancing and thus reach a spiral movement requirement.

Abstract

A handrail belt driving device of a spiral escalator, comprising a driving main engine (1), a step driving main shaft (3), a driving chain (2) connected to the step driving main shaft (3) and the driving main engine (1), and a handrail shaft (7) used for driving a handrail belt to move. At least one transition shaft is provided between the step driving main shaft (3) and the handrail shaft (7); the transition shaft at least comprises an outer side transition shaft (13b) close to an outer side handrail belt (10b) and an inner side transition shaft (13a) close to an inner side handrail belt (10a); a joint between the outer side transition shaft (13b) and the inner side transition shaft (13a) is a universal structure; the step driving main shaft (3) and the inner side transition shaft (13a) synchronously rotate by means of an inner side transition chain (5a), and the handrail shaft (7) and the outer side transition shaft (13b) synchronously rotate by means of an outer side transition chain (5b). The present handrail belt driving device may meet the special requirement of a handrail belt being laterally bent while having the same angular velocity and different linear speed at two sides. In addition, the steps and the handrail belts on both sides may start and stop at the same time, thereby ensuring the safety of the escalator.
