Technical Field

The invention belongs to the technical field of elevator guide rail detection equipment, and particularly relates to an elevator guide rail straightening detection device.

Background

The elevator guide rail is an elevator component composed of steel rails and connecting plates and is divided into a car guide rail and a counterweight guide rail. The cross section is divided into three forms of T shape, L shape and hollow. The guide rail can bear the impact force of the car and the elevator during braking, the impact force of safety tongs during emergency braking and the like while playing a role in guiding. The magnitude of these forces is related to the load weight and speed of the elevator and the guide rails should therefore be fitted according to the speed and load weight of the elevator. The car guide rails are usually referred to as primary rails and the counterweight guide rails as secondary rails.

At present, in the process of detecting the elevator guide rail, the detection device for straightening the elevator guide rail needs to detect different positions of the elevator guide rail, a plurality of parts need to be disassembled for adjusting the detection mechanism, and then the detection mechanism is assembled, so that the detection efficiency of the elevator guide rail is greatly reduced.

Disclosure of Invention

The invention aims to provide an elevator guide rail straightening detection device which does not need repeated disassembly and assembly and has high detection efficiency. In order to achieve the purpose, the invention provides the following technical scheme:

an elevator guide rail straightening detection device comprises a base, wherein a box body, a first vertical plate and a second vertical plate are fixed on the base, and a rotary table is movably connected with the base through a first rotary rod;

the box body is provided with a servo motor at the top, an output shaft of the servo motor is fixedly provided with a lead screw through a coupler, the end part of the lead screw is connected to the bottom of the box body through a bearing, one side of the box body is provided with a window, the lead screw is in threaded connection with a threaded sleeve, the outer surface of the threaded sleeve is fixedly provided with a connecting block, and the end part of the connecting block is provided with a laser;

the both ends of first bull stick are passed through the bearing and are connected carousel and base, there is bevel gear on the first bull stick, there is the horizontally second bull stick to pass through the bearing on first riser and the second riser, there is bevel gear at the tip of second bull stick, with the bevel gear meshing transmission on the first bull stick, the other end of second bull stick has the handle.

Preferably, four groups of supporting columns are fixed on the lower surface of the base, and four groups of rubber bases are fixedly installed on the lower surfaces of the four groups of supporting columns through bolts.

The connecting block passes through the window. The width of the window is 2-4mm larger than that of the connecting block.

When the device is used, the elevator guide rail is placed on the rotary table, the laser is driven to ascend or descend by the rotation of the output shaft of the servo motor, the laser is adjusted to be attached to the upper surface of the elevator guide rail to irradiate, whether a laser spot appears on the second vertical plate or not is observed, and if the laser spot appears, the elevator guide rail is straight. The handle of rotatory second bull stick rotates the carousel, and the position of left and right sides transform elevator guide rail observes the laser point on the second riser, if exist and observe the laser point that can not observe, explains elevator guide rail's quality is unqualified, great improvement elevator guide rail's detection efficiency.
