Counterweight guide rail connecting device for elevator

Abstract

The invention discloses a counterweight guide rail connecting device for an elevator. The two ends of a guide rail cushion board are correspondingly inserted into counterweight guide rails which are to be connected and are fixedly connected or detachably connected with the counterweight guide rails. The guide rail cushion board is fixedly connected with base plates of the counterweight guide railsthrough bolts. The two ends of a connecting plate are correspondingly arranged at the bottoms of the two to-be-connected counterweight guide rails and are fixedly connected with the counterweight guide rails through bolts. The cross section of the connecting plate is of a U-shaped structure and is the same as the cross section of the bottom of each counterweight guide rail. The connecting plate and the guide rail cushion board are each correspondingly provided with a riveting hole; rivets penetrate through the bottom walls of the counterweight guide rails and the riveting holes in order to rivet the connecting plate, the guide rail cushion board and the counterweight guide rails. The connecting plate is connected with each counterweight guide rail through four bolts and two rivets; the two sides of each counterweight guide rail are each uniformly provided with two bolts; and one rivet is arranged between the two corresponding bolts. The counterweight guide rail connecting device for the elevator is simple in overall structure, is convenient to install and use by a worker on the scene and also lowers the production cost and the manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of elevator auxiliary equipment used in residential buildings, in particular to a counterweight guide rail connection device for elevators. Background technique [0002] The elevator guide rail is an elevator component composed of steel rails and connecting plates. It is divided into car guide rails and counterweight guide rails. From the cross-sectional shape, it can be divided into three types: T-shaped, L-shaped and hollow. While the guide rail plays a guiding role, it also bears the impact force of the car and elevator braking, and the impact force of the safety gear during emergency braking. The magnitude of these forces is related to the load and speed of the elevator, so guide rails should be selected according to the speed and load of the elevator. It is usually called the car guide rail as the main rail, and the counterweight guide rail as the auxiliary rail. [0003] In the prior art, the struct...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the structure of the connecting device between the counterweight guide rails is complicated, and each manufacturer has its own connecting parts

Especially for most manufacturers, non-standard parts are usually used, which increases the labor intensity of the installation workers, and the production cost is high

[0004] It can be seen that the counterweight guide rail connection device in the prior art has the disadvantages of complex structure, high manufacturing cost, and inconvenient installation by on-site workers
