Description

Technical Field

[0001] The utility model belongs to the technical field of verticality detection, and in particular relates to a tool for detecting the verticality of an elevator guide rail. Background Art

[0002] The verticality of elevator guide rails is a crucial parameter for safe elevator operation. Excessive vertical deviation can cause shaking and noise during elevator operation, potentially affecting the elevator's stability and safety. Therefore, regular verticality testing of elevator guide rails is a crucial part of elevator maintenance. Traditional methods for testing guide rail verticality rely on manual measurement and calibration, which is not only time-consuming and labor-intensive, but also susceptible to human error. With technological advancements, high-precision measuring equipment such as laser plummets are increasingly being used for guide rail verticality testing.

[0003] However, these devices usually require fixing devices when in use to ensure their accurate alignment and stable adsorption with the elevator guide rails. Existing fixing devices include screw clamping and magnet adsorption. Screw clamping is usually inconvenient to move, which affects the detection efficiency. When the equipment is idle in the magnet adsorption method, the surface of the magnet is prone to adsorb foreign matter. If it is not cleaned before the next use, the position of the equipment and the guide rail will be inaccurate when connected, which seriously affects the inspection accuracy. For this reason, an elevator guide rail verticality detection tool is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide an elevator guide rail verticality detection tool that can protect the fixing device on the detection tool in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] The elevator guide rail verticality detection tool includes a laser plumb line and a receiving target, both of which are movably arranged on the elevator guide rail, and both of which are provided with magnetic seats;

[0007] Also included are:

[0008] An extrusion block is slidably disposed in the magnetic seat;

[0009] The sliding plate is slidably arranged in the magnetic seat, and the sliding plate is squeezed by the squeezing block so that the sliding plate moves laterally.

[0010] As a further optimization scheme of the present invention, a plurality of mounting grooves are provided on the magnetic seat, a baffle is rotatably provided on the mounting groove, a torsion spring is provided between the baffle and the mounting groove, the torsion spring is sleeved on the baffle rotating shaft, movable grooves are provided on both sides of the magnetic seat, limiting grooves are provided at the upper and lower ends of the movable groove, and a mounting seat is provided on the magnetic seat.

[0011] As a further optimization scheme of the present invention, accommodating holes are opened on both sides of the extrusion block, a pushing handle is slidably arranged in the accommodating hole, protrusions are arranged on both sides of the pushing handle, a reset spring is arranged between the pushing handle and the accommodating hole, and an anti-slip plate is arranged at one end of the pushing handle.

[0012] As a further optimization solution of the present invention, a magnet is provided on one side of the sliding plate, and the magnet passes through the side wall of the magnetic seat through the installation groove. A second reset spring is provided between the other side of the sliding plate and the magnetic seat.

[0013] As a further optimization solution of the present invention, the lower end of the extrusion block is provided with an inclined surface, and the other side of the sliding plate is provided with an inclined surface matching the extrusion block, and the extrusion block is connected to the sliding plate in abutting manner.

[0014] As a further optimization solution of the present invention, the magnetic base is connected to the laser plummet and the receiving target through a mounting base.

[0015] The beneficial effects of the present invention are:

[0016] Different from the existing technology, in actual use, the magnet can be stored in the magnetic seat through the cooperation of the extrusion block and the sliding plate, and the baffle can protect the surface of the magnet to avoid wear on the surface of the magnet, and foreign matter is adsorbed on the surface of the magnet when the equipment is idle, resulting in inaccurate position when the equipment is connected to the guide rail, which seriously affects the accuracy of the detection.

[0024] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] like Figure 1 - Figure 6 As shown, the elevator guide rail verticality detection tooling includes a laser plumb line 1 and a receiving target 2. The laser plumb line 1 and the receiving target 2 are both movably arranged on the elevator guide rail, and the laser plumb line 1 and the receiving target 2 are both provided with a magnetic seat 3; it also includes: an extrusion block 4 slidably arranged in the magnetic seat 3, and a sliding plate 5 slidably arranged in the magnetic seat 3, and the sliding plate 5 is squeezed by the extrusion block 4 to cause the sliding plate 5 to move laterally.

[0026] like Figure 2 - Figure 4 As shown, a plurality of mounting grooves 31 are provided on the magnetic base 3, a baffle 32 is rotatably provided on the mounting groove 31, a torsion spring 321 is provided between the baffle 32 and the mounting groove 31, the torsion spring 321 is sleeved on the rotating shaft of the baffle 32, movable grooves 33 are provided on both sides of the magnetic base 3, and limiting grooves 331 are provided at the upper and lower ends of the movable groove 33, a mounting base 34 is provided on the magnetic base 3, and the connection position of the magnetic base 3 with the laser vertical collimator 1 and the receiving target 2 is provided through the provided mounting base 34, and the torsion spring 321 is provided so that the baffle 32 can automatically reset as soon as it loses the driving force.

[0027] like Figure 5 - Figure 6 As shown, accommodating holes 41 are provided on both sides of the extrusion block 4, and a pushing handle 42 is slidably provided in the accommodating hole 41, and protrusions 421 are provided on both sides of the pushing handle 42. A return spring 43 is provided between the pushing handle 42 and the accommodating hole 41, and an anti-slip plate is provided at one end of the pushing handle 42. The protrusion 421 is set to limit the angle of the pushing handle 42 on the extrusion block 4 to facilitate the use of the anti-slip plate on the pushing handle 42, and the cooperation between the protrusion 421 and the limiting groove 331 can limit the position of the pushing handle 42 on the movable groove 33.

[0028] like Figure 5 As shown, a magnet 51 is provided on one side of the sliding plate 5, and the magnet 51 passes through the side wall of the magnetic seat 3 through the mounting groove 31. A reset spring 2 52 is provided between the other side of the sliding plate 5 and the magnetic seat 3. The reset spring 2 52 is provided so that the sliding plate 5 can be reset immediately after losing the extrusion force.

[0029] like Figure 5 As shown, an inclined surface is provided at the lower end of the extrusion block 4, and an inclined surface matching the extrusion block 4 is provided on the other side of the sliding plate 5. The extrusion block 4 is connected to the sliding plate 5 by abutting against it. The inclined surface matching the extrusion block 4 is provided on the other side of the sliding plate 5, so that when the extrusion block 4 moves downward, the sliding plate 5 moves laterally.

[0030] like Figure 1 - Figure 2 As shown, the magnetic base 3 is connected to the laser plummet 1 and the receiving target 2 through the mounting base 34 .

[0031] It should be noted that, when the elevator guide rail verticality detection tool is in use, by pressing the pushing handle 42, the protrusion 421 is withdrawn from the limiting groove 331 at the upper end of the movable groove 33, and then the pushing handle 42 is pushed downward to make the extrusion block 4 move downward to squeeze the sliding plate 5, so that the sliding plate 5 moves laterally. As the sliding plate 5 moves laterally, the magnet 51 extends to the outside of the magnetic seat 3 through the mounting groove 31. During the movement of the magnet 51, the magnet 51 pushes the baffle 32. As the pushing handle 42 moves to the bottom end of the movable groove 33, the pushing handle 42 is released. The pushing handle 42 is reset under the action of the reset spring 43, so that the protrusion 421 is restricted in the limiting groove 331 at the lower end of the movable groove 33, so that the pushing handle 42 is fixed in position, so that the magnet 51 extends to the outer surface of the magnetic seat 3.

[0032] When performing verticality detection, the laser plumb line 1 and the receiving target 2 are vertically adsorbed on the elevator guide rail through the magnet 51 on the magnetic base 3, and the laser plumb line 1 is located directly above the receiving target 2. Then, by observing the position of the laser point emitted by the laser plumb line 1 on the receiving target 2, it is detected whether the elevator guide rail is vertical, and multi-point detection can be performed by moving the receiving target 2.

[0033] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
