[0002] The brake is an important component to ensure the safe and normal operation of the elevator, and plays a role in protecting the lives of users. Therefore, the brake needs to be inspected regularly to ensure the safety of users. During the inspection, the elevator brake detection device is needed.

[0003] When testing the brake detection device, the staff needs to hold the brake detection device by hand, and fit the detection wheel of the detection device tightly with the elevator wire rope so that the detection wheel and the wire rope move synchronously to complete the detection. However, the contact between the wire rope and the single detection wheel is completely operated by the staff by hand. A slight movement can separate the detection wheel from the wire rope, which not only easily causes deviations in the detection results, but also the staff holds the device for a long time, which puts a heavy workload on them. Therefore, we propose an elevator brake detection device to solve the above problems. Summary of the invention

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0021] The present application provides an elevator brake detection device, which is mainly used to solve the problem that in the prior art, the contact between the wire rope and a single detection wheel is completely operated by the staff, and a slight movement can separate the detection wheel from the wire rope, which not only easily causes deviations in the detection results, but also the staff holds the device for a long time, which has a heavy workload, and provides the following technical solutions. Figure 1-Figure 2 Make a detailed description:

[0022] An elevator braking detection device, comprising:

[0023] A mounting seat 1 is arranged at the ground opening ring frame of the wire rope in the elevator room. The mounting seat 1 is dustpan-shaped, and a mounting block 2 is slidably arranged at its open end;

[0024] The braking capacity tester body 3 is detachably arranged at the front end of the mounting block 2, and the detection wheel of the braking capacity tester body 3 is arranged at the end thereof away from the mounting block 2;

[0025] The displacement mechanism 4 is used to adjust the front and rear position of the mounting block 2. The displacement mechanism 4 includes a rotating rod 401 rotatably connected between the inner side walls of the mounting seat 1. The two sides of the rotating rod 401 are configured with threads with opposite spiral directions, and the sliding blocks 402 are symmetrically threadedly connected. The side of the sliding block 402 close to the mounting block 2 is hinged to a hinge plate 403, and the side of the hinge plate 403 away from the sliding block 402 is hinged to the mounting block 2.

[0026] The support frame 5 is used to fix the mounting base 1 on the ground opening ring frame of the wire rope in the elevator room. The support frame 5 includes support rods 501 fixedly arranged at intervals on both sides of the mounting base 1. A limit plate 502 is fixedly arranged at one end of the support rod 501 away from the mounting base 1, and a locking piece is arranged on the surface of the support rod 501 to prevent it from moving forward and backward.

[0027] The specific implementation process and principle description of the elevator brake detection device:

[0028] The first step is to move the mounting base 1 to the open ring frame of the steel wire rope on the ground in the elevator room, fix the support rod 501 to the outside of the open ring frame through spring tension, and fix the support rod 501 with a locking piece so that it does not move forward and backward, thereby ensuring that the position of the mounting base 1 is relatively stable;

[0029] The second step is to install the braking capacity tester body 3 on the front end of the mounting block 2;

[0030] The third step is to rotate the rotating rod 401 according to the position to be detected, and the sliders 402 on both sides can move towards each other or move away from each other. The mounting block 2 can be pushed forward and backward through the hinged plate 403. This design makes the contact between the detection wheel and the elevator wire rope closer, ensuring the accuracy of the detection data.

[0031] The elevator brake detection device is provided with a support frame 5 with a locking piece, so that the mounting seat 1 can be fixed on the ground opening ring frame of the wire rope in the elevator room. The staff does not need to hold the device for a long time, which reduces the workload. In addition, the front and rear positions of the mounting block 2 can be adjusted through the displacement mechanism 4, so that the detection wheel of the braking capacity tester is closely fitted with the wire rope, reducing the deviation of the detection result.

[0032] It should be noted that the braking capacity tester body 3 is a prior art, and its working principle will not be described in detail.

[0033] like Figure 1 As shown, in some embodiments, a mounting groove 201 is provided at the front end of the mounting block 2, and the braking capacity tester body 3 is slidably embedded in the interior of the mounting groove 201. The top of the mounting groove 201 is threadedly connected with a locking bolt 6. More specifically, the mounting groove 201 is used to embed the braking capacity tester body 3. The design of the mounting groove 201 allows the tester body to be firmly fixed on the mounting block 2 to ensure that it will not move or shake during the detection process. The locking bolt 6 can fix the tester body to prevent it from loosening or moving during the detection process. The design of the locking bolt 6 ensures the firmness and stability of the installation, further improving the accuracy and reliability of the detection.

[0034] like Figure 1 As shown, in some embodiments, the width of the mounting groove 201 is greater than the width of the braking capacity tester body 3, the number of locking bolts 6 is at least three, and they are evenly spaced at the top of the mounting groove 201. More specifically, the larger width of the mounting groove 201 simplifies the steps of placing the braking capacity tester body 3 into the groove, and improves the installation efficiency. Through the locking bolts 6 arranged at equal intervals, the staff can fine-tune the position of the braking capacity tester body 3 left and right until the detection wheel accurately corresponds to the position of the elevator wire rope, thereby ensuring the accuracy of the detection.

[0035] like Figure 1 As shown, in some embodiments, one end of the rotating rod 401 passes through the side wall of the mounting base 1 and is connected to a knob 404 . More specifically, the design of the knob 404 allows the user to easily adjust the position of the rotating rod 401 .

[0036] like Figure 2 As shown, in some embodiments, the locking member includes an L-shaped plate 503 slidably mounted on the surface of the support rod 501, and a spring 504 is connected between the L-shaped plate 503 and the side wall of the mounting seat 1, and the spring 504 is mounted on the surface of the support rod 501. More specifically, the support rod 501 is placed at the ground opening ring frame of the wire rope in the elevator room, and the position is adjusted so that it properly supports the mounting seat 1. Under the tension of the spring 504, the L-shaped plate 503 conflicts with the outer edge of the ground opening ring frame of the wire rope in the elevator room, and the staff can fix the device on the top of the L-shaped plate 503. Through the design of the L-shaped plate 503 and the spring 504, the elevator brake detection device can achieve rapid positioning and stable fixation, which is convenient for the staff to detect the braking capacity.

[0037] like Figure 2As shown, in some embodiments, the top of the L-shaped plate 503 is constructed with anti-slip grooves. More specifically, the anti-slip grooves increase the friction coefficient of the top of the L-shaped plate 503, so that the grip between the soles of the workers and the L-shaped plate 503 is enhanced when the staff stands. The anti-slip grooves can provide more stable support and prevent accidental sliding or displacement.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
