Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] figure 1 A pneumatic traction system according to an embodiment of the invention is schematically shown.

[0023] Such as figure 1 As shown, the pneumatic traction system includes a traction cylinder 1, a speed governor 2, a wire rope assembly 3, a pull rod assembly 4 and a pneumatic system 5. The traction cylinder 1 is installed vertically on the left side of the car 6, and the speed governor 2 is bolted to the connecting plate at the bottom of the traction cylinder 1, and the piston rod 11 of the traction cylinder 1 is screwed to the pulley block 32. The wire rope assembly 3 includes a ground wheel 31, a block pulley 32, a pull-up wire rope 33 and a pull-down wire rope 34, and the ground wheel 31 is connected with the pit bolts.

[0024] Such as figure 2 , 3 As shown, the pulley block 32 includes an upper pulley 321, a lower pulley 322 and a pu...

Abstract

The invention discloses a pneumatic traction system, which comprises a traction air cylinder, a speed limiter, a steel wire rope assembly and a pull rod assembly, wherein the speed limiter is arranged at the outer side of the dragging air cylinder, a piston rod of the dragging air cylinder is connected with the steel wire rope assembly, and the steel wire rope assembly bypasses the speed limiter, is connected with the pull rod assembly and is tightly pulled. The pneumatic traction system has the advantages that through the structural design of linking a traction system with a safety protection system mechanism, the structure is simplified, the manufacturing cost is low, meanwhile, the work is stable, and safety and reliability are realized.

Description

technical field [0001] The invention relates to the field of traction elevators, in particular to a traction system whose power source is provided by a pneumatic system. Background technique [0002] In the existing traction elevator, there is no structural connection between the traction system and the safety protection system, and it cannot play the role of mechanism linkage, so the structure of the two is complicated, which increases the manufacturing cost, and also brings work stability and safety. safety and reliability issues. Contents of the invention [0003] The purpose of the present invention is to provide a pneumatic traction system, which reduces the manufacturing cost of the elevator by simplifying the structure of the traction system and the safety protection system, and makes it work stably, safely and reliably. [0004] According to one aspect of the present invention, a pneumatic traction system is provided, including a traction cylinder, a speed governo...
