Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide rails, in particular to a hollow elevator guide rail straightening mechanism. Background Art

[0002] Elevator guide rails are elevator components composed of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails. They are divided into three types according to the cross-sectional shape: T-shaped, L-shaped and hollow. While playing a guiding role, the guide rails bear the impact force of the car and elevator during braking, the impact force of the safety clamp during emergency braking, etc. However, general hollow elevator guide rails are not straight after production. If the elevator guide rails are used directly without straightening, it is easy to cause the elevator car to shake, or even a safety accident. For this reason, we have launched a hollow elevator guide rail straightening mechanism.

[0003] For example, the Chinese patent with publication number CN214442023U discloses a hollow elevator guide rail straightening mechanism, comprising a workbench and a bottom plate, a groove is provided inside the workbench, and a bottom plate is provided inside the groove, a lower straightening block is welded at the center position of the top surface of the bottom plate, and two sides of the lower straightening block are located on the top surface of the bottom plate and are rotatably connected with side straightening wheels, and an upper straightening block is provided above the lower straightening block. In the utility model, by setting a driving motor, a screw rod, a threaded block, a bottom plate, a lower straightening block, an upper straightening block, side straightening wheels, a limit groove and a limit block for mutual use, the output end of the driving motor drives the screw rod to rotate forward and reversely, and drives the bottom plate to move left and right under the action of the limit groove and the limit block, thereby driving the two side straightening wheels to rotate in the opposite direction, and the purpose of straightening the hollow elevator guide rail is achieved under the cooperation of the upper straightening block and the lower straightening wheel, thereby improving the straightening effect, reducing the labor of manual straightening of the staff, and improving the work efficiency of straightening the hollow elevator guide rail.

[0004] The existing technology has the following problems:

[0005] The straightening machine of the prior art does not heat the hollow guide rail when straightening the hollow guide rail, resulting in greater resistance of the hollow guide rail during straightening. At the same time, the friction generated by the straightening roller and the hollow guide rail during straightening causes the hollow guide rail to heat up, making it inconvenient to remove it later. However, the prior art does not dissipate heat and cool the hollow guide rail. Utility Model Content
