Tractor protective cover

Abstract

The invention relates to a protective cover used for a tractor. According to the tractor protective cover, protective segmental plates capable of being bent in various manners are manufactured into protective covers of various types for achieving different purposes of traction wheel side face protection, incliner lateral traction steel wire rope protection, guide pulley side face protection and protection of spaces in a rack. Wing plates of the protective covers of various types are provided with long-kidney holes or circular holes, and the long-kidney holes and the circular holes are used for installing the protective covers of various types on the tractor and or the rack, or enabling the protective covers of various types to be installed in a mutually connected mode. The circular holes in the wing plates on the protective covers of various types can also be used for fixedly installing riveting pressure nuts or enabling the riveting pressure nuts to be installed in the mutually connected mode or installing front protective plates. Circular holes in the middle plate surfaces of the protective segmental plates can also be used for fixedly installing the riveting pressure nuts, and every two independent protective segmental plates are connected through connecting plates. The tractor protective cover is single in specification, convenient to manufacture and capable of being applicable to the tractors of various types, the tractor protective cover can be cut and used as needed according to the matched size length and can be used in a lap joint mode during undersize, material waste is reduced, and universality is high.

Description

technical field [0001] The invention belongs to the technical field of elevators and relates to a traction machine protective cover. . Background technique [0002] In the traction type hoisting mechanism, the elevator traction machine is installed on the frame in the machine room, and the traction wire rope is not only suspended on the traction wheel of the traction machine, but also on the guide wheel. The two ends of the traction wire rope are respectively connected to the car and the counterweight. The gravity of the car and the counterweight makes the traction wire rope tightly pressed in the rope groove of the traction wheel and the guide wheel, so that there is a gap between the traction wire rope and the traction sheave. Friction (also called traction). When the traction sheave rotates, the traction wire rope drives the car and the counterweight to move relative to each other to realize the up and down lift of the car. [0003] In the elevator industry, the centra...

Problems solved by technology

However, in the methods in the prior art, the specifications of some parts used are still too many, and the lower part of the traction wire rope on the oblique side part cannot be effectively protected, which may still cause personal injury, and there are also gaps between the frames that are not properly protected. If the protective taker fails, it is possible to drop objects or tools into the elevator shaft and cause equipment damage
