[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] Example: Figures 1-6 As shown, this utility model provides a quality inspection device for steel rail turnout pads, including a first fixed frame 1, a second fixed frame 3 fixedly installed on one side of the first fixed frame 1, a second inspection device 33 fixedly installed at the top center of the second fixed frame 3, a first double-ended screw 2 rotatably installed on one side of the top of the first fixed frame 1, gears 21 fixedly installed on both sides of the first double-ended screw 2, two symmetrically distributed limiting plates 25 threaded on the outer surface of the first double-ended screw 2, a first inspection device 26 fixedly installed at the top center of the two limiting plates 25, a toothed plate 22 provided on one side of each of the two gears 21, the two toothed plates 22 meshing with the gears 21, a placement plate 24 fixedly installed at the top of the two toothed plates 22, a plurality of evenly distributed slots 241 opened on the upper part of the placement plate 24, the lower parts of the two limiting plates 25 slidingly opened inside the slots 241, a spring 11 fixedly installed at the top center of the first fixed frame 1, and the top of the spring 11 fixedly installed at the bottom of the placement plate 24.

[0020] A second double-ended screw 29 is rotatably mounted in the middle of the placement plate 24, and two symmetrically distributed clamping plates 27 are threaded on the outer surface of the second double-ended screw 29.

[0021] A telescopic rod 12 is fixedly installed at the top center of the first fixing frame 1. The top of the telescopic rod 12 is fixedly installed at the bottom center of the placement plate 24. By setting the telescopic rod 12, the spring 11 can be protected and the spring 11 can be prevented from being damaged by excessive compression.

[0022] The upper side of the first fixing frame 1 is provided with a first sliding groove 13, the bottom end of each of the two limiting plates 25 is fixedly provided with a first sliding block 14, and the two first sliding blocks 14 are slidably clamped in the first sliding groove 13. Through the first sliding groove 13 and the first sliding block 14, the bottom end of the limiting plate 25 is limited.

[0023] The upper side of the second fixing frame 3 is provided with a second sliding groove 31, the upper side of each of the two limiting plates 25 is fixedly provided with a second sliding block 32, and the two second sliding blocks 32 are slidably clamped in the second sliding groove 31. Through the second sliding groove 31 and the second sliding block 32, the upper side of the limiting plate 25 is limited under the limitation of the second sliding groove 31 on the second sliding block 32, so that the limiting plate 25 is more stable during movement.

[0024] The middle of the second fixing frame 3 is fixedly provided with two symmetrically distributed limiting rods 23, and one side of each of the two tooth plates 22 is slidably clamped on the outer surface of the limiting rod 23. Through the limiting rod 23, one side of the tooth plate 22 is limited, and the stability of the tooth plate 22 moving up and down is ensured.

[0025] The top end of the placing plate 24 is provided with a groove 28 in the middle, and the lower part of each of the two clamping plates 27 is slidably clamped in the groove 28. Through the groove 28, the lower part of the clamping plate 27 is limited, so that the two clamping plates 27 can be stably moved relative to or away from each other under the rotation of the second double-headed screw rod 29.

[0026] One end of the second double-headed screw rod 29 penetrating the placing plate 24 is fixedly provided with a handle 291. Through the handle 291, the second double-headed screw rod 29 is rotated.

[0027] Working principle: in actual use, the mat to be detected is placed on the placing plate 24, and the placing plate 24 moves downward under the gravity of the mat, so that the tooth plate 22 moves downward, i.e. the gear 21 is rotated, thereby driving the first double-headed screw rod 2 to rotate, and the two limiting plates 25 screwed on the outer surface of the first double-headed screw rod 2 move relative to each other, i.e. the two ends of the mat are close to each other. Through the work of the first detection device 26, the distance between the mat and the two limiting plates 25 is detected. If the distance does not meet the requirements, it means that the quality of the mat, i.e. the weight of the mat, does not meet the requirements. On the contrary, it meets the requirements. At the same time, the outer tube of the mat is detected by the second detection device 33. The flatness, trimming neatness, and whether there are cracks, peeling and other defects of the mat are detected by image recognition technology. When the detection is completed, the mat is taken off from the upper part of the placing plate 24, and under the action of the reaction force of the spring 11, the placing plate 24 is reset, thereby facilitating the next use.

[0028] By rotating the handle 291, the second double-headed screw 29 can be rotated, i.e. the two clamping plates 27 are driven to move towards or away from each other, so as to adjust the distance between the two clamping plates 27, so that when the same specification of the pad is detected, the distance between the clamping plates 27 can be adjusted to limit the direction of the pad, so as to ensure that the position of the pad is not deviated or inclined, thereby avoiding affecting the detection effect.

[0029] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, without departing from the technical solution of the present application. Any modification, equivalent change and modification of the above embodiments according to the technical essence of the present application still belong to the scope of the technical solution of the present application.
