Description

Technical Field

[0001] This application relates to the field of elevator testing technology, specifically an elevator brake testing device. Background Technology

[0002] The elevator brake is an important safety device for elevators, and its safety and reliability are one of the key factors in ensuring the safe operation of elevators.

[0003] The current testing device used to test the braking performance of elevator brakes is an elevator brake tester. During testing, the front wheel of the tester rotates close to the wire rope, and the wire rope drives the front wheel to rotate. When the elevator reaches the set travel distance or rated speed, the tester will send an elevator braking signal and start measuring the travel distance of the wire rope. After the elevator stops, the tester will display and record the test results.

[0004] For example, patent CN216105430U discloses an elevator brake performance testing device. This patent uses a base plate, a first lead screw, a first sliding block, an adjusting plate, a second lead screw, a second sliding block, a first rotating disk, and a second rotating disk. In actual use, the base plate can be fixed in a designated position, and the first and second rotating disks can be rotated. The rotation of the first and second rotating disks drives the first and second lead screws to rotate, and the rotation of the first and second lead screws adjusts the position of the elevator brake tester body through the first and second sliding blocks.

[0005] During normal operation of an elevator, the steel wire rope may tilt to a certain extent due to various factors (such as uneven loading of the car, unevenness of the guide rail, etc.). However, the above-mentioned patent only made horizontal and vertical adjustments on the plane. In order to simulate the real operating state of the elevator and accurately evaluate the braking performance, the front wheel of the elevator braking tester needs to be tilted to the same angle as the steel wire rope during the test to achieve more accurate test results.

[0006] Therefore, it is necessary to provide an elevator brake testing device to solve the above problems.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0037] like Figures 1-2 As shown, this application provides an elevator brake testing device, including a base 1 and an adjustment mechanism 2 disposed on the upper end of the base 1. The adjustment mechanism 2 is used to adjust the elevator brake tester in multiple directions during the testing process.

[0038] The adjustment mechanism 2 includes a lateral adjustment component 21. The lateral adjustment component 21 adopts a screw drive mechanism commonly used in the prior art and applicable to this embodiment, which is used to move the elevator brake tester laterally. The lateral adjustment component 21 also has a first slider 211 and a first handwheel 210, so that the operator can drive the first slider 211 to slide laterally by rotating the first handwheel 210.

[0039] Meanwhile, in order to enable the elevator brake tester to be adjusted in multiple directions during testing, a longitudinal adjustment component 22 is provided on the upper end of the first slider 211. The longitudinal adjustment component 22 includes a fixed plate 220 fixedly installed on the upper end of the first slider 211. Multiple sets of slide grooves 221 are provided on the fixed plate 220. Sliding blocks 222 are slidably installed on the slide grooves 221, so that when testing, the staff can move the elevator brake tester longitudinally by moving the sliding blocks 222.

[0040] Furthermore, multiple sets of positioning holes 224 are opened on both sides of the fixed plate 220, and locking bolts 223 are threadedly connected to the positioning holes 224. The locking bolts 223 pass through the positioning holes 224 and directly contact the sliding block 222. Before testing, when the staff moves the elevator brake tester to a suitable position by moving the sliding block 222, they can rotate the locking bolts 223 to move it closer to the sliding block 222 until it is locked. When it is necessary to move it, simply rotate the locking bolts 223 away from the sliding block 222 to unlock it.

[0041] like Figures 2-5As shown, in order to tilt the front wheel of the elevator brake tester to the same angle as the wire rope during the test, thereby simulating the real operating state of the elevator and accurately evaluating the braking performance, an angle adjustment mechanism 3 is provided on the upper end of the sliding block 222.

[0042] The angle adjustment mechanism 3 includes a column 30 fixedly installed on the upper end of the sliding block 222, and a mounting plate 31 fixedly installed on the column 30. The mounting plate 31 has a through hole 37 in the middle position, and a stabilizing plate 36 is hinged to one end of the mounting plate 31 at the through hole 37.

[0043] Meanwhile, in order to lock the elevator brake tester, a locking component 39 is provided on the stabilizing plate 36. The locking component 39 includes a stop bar 390 fixedly provided at one end of the stabilizing plate 36, and a locking seat 391 fixedly provided at the other end of the stabilizing plate 36. A third screw 392 is threadedly connected to the locking seat 391. One end of the third screw 392 passes through the locking seat 391 and is rotatably provided with a pressure bar 393. Thus, before the test begins, the elevator brake tester is first placed on the stop bar 390. Then, one end of the third screw 392 is rotated to push the pressure bar 393 along the stabilizing plate 36 closer and closer to the stop bar 390 until it contacts the elevator brake tester and presses it down.

[0044] Furthermore, a fixing seat 32 is fixedly installed on both sides of the through hole 37 at one end of the mounting plate 31, and a second screw 33 is rotatably installed between the two sets of fixing seats 32. A handle 38 is fixedly installed at one end of the second screw 33 so that the second screw 33 can be driven to rotate between the two sets of fixing seats 32 by rotating the handle 38.

[0045] Meanwhile, a spiral block 34 is threaded onto the second screw 33, and a support plate 35 is hinged to the upper end of the spiral block 34. The other end of the support plate 35 passes through the through hole 37 and is hinged to the middle position of the stabilizing plate 36. Thus, when the angle needs to be adjusted, the operator can drive the second screw 33 to rotate by turning the handle 38, thereby driving the spiral block 34 to move along the through hole 37. During the movement, the spiral block 34 can push the stabilizing plate 36 to rotate around one end of the mounting plate 31 through the support plate 35, thereby achieving the purpose of adjusting the angle of the stabilizing plate 36.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
