[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A pendulum friction coefficient tester comprises a base 1, a clamping assembly 2 is arranged on one side of the base 1, a lifting assembly 3 is arranged on one side of the clamping assembly 2, a detection assembly 4 is arranged on the top of the base 1, a collecting assembly 5 is arranged on the top of the base 1, a recovery assembly 6 is arranged on one side of the collecting assembly 5, and an anti-splash assembly 7 is arranged on the top of the base 1;

[0031] The clamping assembly 2 includes a supporting leg 201, a detection slot 202, a supporting frame 203, a square block 204, a motor 205, a rotating column 206, a rotating rod 207, a connecting rod 208, a clamping plate 209 and a placement block 210. The two supporting legs 201 are fixedly connected to the bottom of the base 1, the detection slot 202 is opened at the top of the base 1, the supporting frame 203 is fixedly connected to the bottom of the base 1, the square block 204 is arranged inside the supporting frame 203, the motor 205 is arranged inside the square block 204, the rotating column 206 is fixedly connected to the output end of the motor 205, the rotating rod 207 is fixedly connected to one side of the rotating column 206, the two connecting rods 208 are respectively hinged at both ends of the rotating rod 207, the two clamping plates 209 are slidably connected to the top of the square block 204 and are respectively hinged to the two connecting rods 208, and the two placement blocks 210 are fixedly connected to the top of the square block 204.

[0032] Specifically, Figure 3As shown, the lifting assembly 3 includes a lifting plate 301, a lifting slot 302 and a hydraulic rod 303. The lifting plate 301 is connected between the two supporting legs 201. The lifting slot 302 is opened at the bottom of the supporting frame 203. One end of the hydraulic rod 303 is bolted to the top of the lifting plate 301 and the other end is slidably connected to the inside of the lifting slot 302 and fixedly connected to the bottom of the square block 204.

[0033] Specifically, Figure 5 As shown, the detection component 4 includes an extension column 401, a dial 402, a pointer 403, a pendulum 404 and a block 405. The extension column 401 is fixedly connected to the top of the base 1, the dial 402 is fixedly connected to one side of the extension column 401, the pointer 403 is arranged on one side of the dial 402, the pendulum 404 is arranged on one side of the pointer 403, and the block 405 is arranged on one side of the extension column 401 and used in conjunction with the pendulum 404.

[0034] When in use, the test sample is placed on the two placement blocks 210, and then the motor 205 is started to drive the rotating column 206 to rotate. The rotating column 206 pulls the connecting rod 208, driving the two clamping plates 209 to slide synchronously on the square block 204 and clamp the test sample. Then the hydraulic rod 303 is started. The hydraulic rod 303 supports the square block 204 to make the square block 204 slide and rise inside the supporting frame 203, driving the test sample to rise to a suitable height. Finally, the friction coefficient of the test sample is tested by lowering the pendulum 404, so that the test sample can be clamped and fixed in the center of the test location, so that the height of the sample can be adjusted, thereby improving the accuracy of the test.

[0035] Specifically, Figure 3 As shown, the collecting assembly 5 includes a collecting tank 501 and a collecting grid 502 . The collecting tank 501 is opened at the top of the base 1 , and the collecting grid 502 is arranged at the top of the collecting tank 501 .

[0037] Specifically, Figure 5 As shown, the splash-proof assembly 7 includes a slot 701 and a protective plate 702 . The slot 701 is opened at the top of the base 1 , and the protective plate 702 is inserted into the slot 701 .

[0038] During use, the splashing residue generated by the detection will be blocked by the protective plate 702 and fall into the interior of the recovery box 602 through the collection grid 502 for collection, which can prevent the residue from splashing and affecting the surrounding environment, so that the residue generated by the detection can be collected and recycled, which is simple and convenient to use.

[0040] Specifically, Figure 5 As shown, a plurality of stabilizing plates 12 are fixedly connected to one side of the supporting leg 201 , and the internal threads of the stabilizing plates 12 are connected to the stabilizing columns 13 .

[0041] When in use, the universal wheel 11 can facilitate the movement of the base 1. When the base 1 is tilted due to uneven ground, the stabilizing column 13 is rotated in the corresponding direction to drive the stabilizing column 13 to move down inside the stabilizing plate 12 and support the ground, so that the base 1 is successfully leveled without affecting the detection.

[0042] By adopting the above technical solution, the problem that the existing pendulum friction coefficient tester cannot keep the test sample in the center during actual use is solved. Each time the sample is replaced, the next sample cannot be kept in the same position as the previous sample, and the position deviation causes errors in the inspection data. At the same time, the debris generated by the test cannot be collected.

[0043] Working principle: When the present application is in use, the test sample is first placed on the two placement blocks 210, and then the motor 205 is started to drive the rotating column 206 to rotate, and the rotating column 206 pulls the connecting rod 208, driving the two clamping plates 209 to slide synchronously on the square block 204 and clamp the test sample, and then the hydraulic rod 303 is started, and the hydraulic rod 303 supports the square block 204 so that the square block 204 slides and rises inside the support frame 203, driving the test sample to rise to a suitable height, and finally the friction coefficient of the test sample is tested by lowering the pendulum 404, so that the test sample can be clamped and fixed in the center of the test location, so that the height of the sample can be adjusted, and the accuracy of the test is improved. The splashed residue generated by the test will be blocked by the protective plate 702 and fall into the inside of the recovery box 602 through the collection grid 502 for collection, which can prevent the residue from splashing and affecting the surrounding environment, so that the residue generated by the test can be collected and recycled, and it is simple and convenient to use.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
