Description

Technical Field

[0001] This utility model relates to the field of elevator testing technology, specifically an elevator braking capacity testing device. Background Technology

[0002] To verify whether the elevator's braking capacity meets safety standards and to ensure that the elevator has reliable emergency braking performance during operation, thus effectively preventing safety accidents caused by braking failure, inspectors often conduct regular elevator inspections. During the inspection process, a traction braking capacity tester is usually used to conduct professional testing on the elevator.

[0003] When using a traction brake capacity tester, its front-end wheel needs to rotate and approach the running wire rope. The wire rope drives the wheel to rotate, thus collecting relevant data. Because the front-end wheel is in direct contact with the wire rope, the tester must be close to the wheel when holding the terminal. This indirectly brings them into contact with the running wire rope, which is moving at high speed. If the tester holds the terminal too close, they may face the risk of being scratched or entangled by the wire rope, or even come into contact with hot debris generated by friction, thus posing a safety hazard. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an elevator braking capacity testing device, making the main body of the testing instrument safer to use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an elevator braking capacity testing device, comprising a testing instrument body, a base plate installed at the bottom of the testing instrument body, a lower plate slidably connected to the bottom of the base plate, a fixed clamping plate fixedly connected to one end of the bottom of the lower plate, a fixed plate fixedly connected to the other end of the bottom of the lower plate, a lead screw threadedly connected to the middle position of the fixed plate, and a movable clamping plate rotatably connected to the end of the lead screw near the fixed clamping plate.

[0006] Furthermore, slots are provided on both sides of the main body of the detector, and elastic blocks are engaged inside the slots, with the elastic blocks being fixedly connected to the base plate.

[0007] Furthermore, the bottom of the base plate is fixedly connected to multiple sliders, and the top of the lower plate is provided with a groove that matches the sliders.

[0008] Furthermore, both sides of the lead screw are provided with positioning plates that are slidably connected to the fixed plate, and one end of the positioning plate is fixedly connected to the movable clamping plate.

[0009] Furthermore, inner side plates are fixedly connected to both sides of the base plate, and outer side plates are fixedly connected to both sides of the lower plate. A limiting groove is opened on the side of the inner side plate near the outer side plate. A limiting block is slidably connected inside the limiting groove. A threaded post is fixedly connected to one side of the limiting block. A positioning groove matching the threaded post is opened in the middle of the outer side plate. A nut is threadedly connected to the end of the threaded post away from the limiting block.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] Before using this elevator braking capacity testing device, the front end of the testing instrument body can be brought close to the elevator wire rope. Then, the testing instrument body is placed on a nearby frame, such as an I-beam used for elevator installation. Next, the screw is rotated to push the movable clamping plate towards the fixed clamping plate until the frame, such as the I-beam, is clamped by the fixed and movable clamping plates.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-5An elevator braking capacity testing device includes a testing instrument body 1, a base plate 4 installed at the bottom of the testing instrument body 1, a lower plate 6 slidably connected to the bottom of the base plate 4, a fixed clamping plate 8 fixedly connected to one end of the bottom of the lower plate 6, a fixed plate 9 fixedly connected to the other end of the bottom of the lower plate 6, a lead screw 12 threadedly connected to the middle position of the fixed plate 9, and a movable clamping plate 10 rotatably connected to one end of the lead screw 12 near the fixed clamping plate 8.

[0020] Before using the elevator braking capacity testing device of this utility model, the front end wheel of the testing instrument body 1 (traction drive elevator braking capacity testing instrument) can be pressed tightly against the elevator wire rope. Then, the testing instrument body 1 is placed on a nearby frame, such as an I-beam used for elevator installation. Next, the screw 12 is rotated to push the movable clamping plate 10 towards the fixed clamping plate 8 until the frame, such as the I-beam, is clamped by the fixed clamping plate 8 and the movable clamping plate 10. In this way, the testing instrument body 1 can be fixed near the wire rope. This avoids the testing personnel from holding the testing instrument body 1 close to the running wire rope during the testing process, reducing safety hazards. In addition, the testing instrument body 1 in this utility model is an existing mature product, so it will not be described in detail here, nor is it shown in detail in the figure.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, slots 2 are provided on both sides of the main body 1 of the detector. Elastic blocks 3 are engaged inside the slots 2 and are fixed to the base plate 4.

[0022] Specifically, the base plate 4 and the main body 1 of the detector are quickly connected by the elastic block 3 and the slot 2, so that the base plate 4 of different sizes can be replaced in different scenarios, making it easier to fix the main body 1 of the detector near the wire rope.

[0023] like Figure 3 and Figure 4 As shown, a plurality of sliders 5 are fixed to the bottom of the base plate 4, and a groove 7 matching the sliders 5 is provided on the top of the lower plate 6.

[0024] Specifically, the base plate 4 and the lower plate 6 are slidably connected, which allows the detector body 1 to move so that the front end wheel of the detector body 1 can be pressed against the elevator wire rope.

[0025] like Figure 2 As shown, both sides of the lead screw 12 are provided with positioning plates 11 that are slidably connected to the fixed plate 9, and one end of the positioning plate 11 is fixedly connected to the movable clamping plate 10.

[0026] Specifically, the positioning plate 11 restricts the movable clamping plate 10, making the movable clamping plate 10 more stable and convenient to move.

[0027] like Figure 3 and Figure 5 As shown, inner side plates 13 are fixed to both sides of the base plate 4, and outer side plates 18 are fixed to both sides of the lower plate 6. A limiting groove 14 is opened on the side of the inner side plate 13 near the outer side plate 18. A limiting block 15 is slidably connected inside the limiting groove 14. A threaded post 16 is fixed to one side of the limiting block 15. A positioning groove 19 matching the threaded post 16 is opened in the middle of the outer side plate 18. A nut 17 is threadedly connected to the end of the threaded post 16 away from the limiting block 15.

[0028] Specifically, after the lower floor plate 6 is fixed to the elevator frame, if the front wheel of the detector body 1 is difficult to fit tightly with the wire rope, the nut 17 can be loosened first, and then the base plate 4 can be pushed to make the front wheel of the detector body 1 fit tightly with the wire rope. After the detector body 1 is moved to a suitable position, the nut 17 can be tightened to fix the base plate 4 and the lower floor plate 6 together, thereby fixing the detector body 1.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
