Guide rail straightness regulating device

Abstract

The invention discloses a straightness adjusting device for a guide rail, which comprises a cam or eccentric wheel adjusting mechanism capable of applying a stepless continuous controllable extrusion force to the guide rail or a beam, and a fixing device for fixing the adjusting mechanism. The adjusting mechanism comprises a cam (1), a sliding block (4), a sliding block moving guide rail (2), and a set screw (5) for fixing the sliding block (4) into the cam sliding block moving guide rail (2), wherein the cam (1) capable of rotating around the cam center thereof is movably arranged on the cam sliding block (4), and the sliding block (4) can move in the sliding block moving guide rail (2). The cam (1) is provided with a matched force application part convenient for a tool to apply a force to rotate the cam (1). The straightness adjusting device has the advantages of novel structure, convenient adjustment and time and labor conservation, can effectively control adjusting amount, is in particular suitable for fine adjustment, improves adjustment accuracy of the straightness of the guide rail greatly, has a simple structure, is convenient to carry, and can be widely applied to adjustment of straightness accuracy of elevator guide rails or other beams.

Description

technical field [0001] The invention relates to a guide rail straightness adjustment device, especially for the installation and adjustment of elevator guide rails, and can also be used for elevator maintenance and reconstruction, and for the correction of elevator guide rails, and can also be used for adjustment and correction of other guide rails, such as rails and steel beams. and a rail installation aid for adjustment. Background technique [0002] Recently, the elevator industry has developed rapidly, and people's requirements for elevators have also been continuously improved, and the speed of elevators has also been continuously increased. Since the trajectory of elevators is usually in the vertical direction, the straightness of the elevator directly affects the operation of the elevator. quality, and even the safe operation of the elevators. Therefore, it is particularly important to adjust the straightness, especially for medium and high-speed elevators. Since the...

Problems solved by technology

[0003] In the existing technical field, the usual way to install and adjust elevator guide rails is to first position the guide rails on the template line or use lasers, and then install the elevator guide rails along the template lines or lasers. When adjustments are required, the most conventional method is to It is to hit the guide rail with a hammer or other tools. This method has extremely adverse consequences. First, the amount of adjustment is extremely difficult to control, and the amount of deformation can only be controlled by hand strength. Repeatedly knock back on the other side; second, the accuracy of the manual knocking method is not easy to control, and it is only up to millimeters, which is not very accurate; third, because the elevator guide rails are connected together from bottom to top, after the guide rails are knocked hard , often affects other rails and rail brackets, and even causes deformation
