DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0030] Please refer to Figures 1-9 The present application provides a technical solution: a mechanical detection device for railway wagon maintenance, comprising a detection machine main body 1, a telescopic cylinder 2 connected to the inside moving block position of the detection machine main body 1, a calibration frame 3 rotationally connected to the output end of the telescopic cylinder 2, a transmission block 4 slidingly connected to the inside of the calibration frame 3, an L-shaped plate 5 connected to the inside end of the transmission block 4 in the calibration frame 3, and the L-shaped plate 5 slidingly connected with the calibration frame 3, a connecting rod 6 hinged to one side of the L-shaped plate 5, and a calibration block 7 hinged to the other end of the connecting rod 6, and the calibration block 7 slidingly connected with the calibration frame 3, a sliding rod 8 slidingly connected to the calibration block 7, and a T-shaped block 9 connected to the other end of the sliding rod 8, a transmission telescopic rod 10 connected to the T-shaped block 9, and the output end of the transmission telescopic rod 10 connected with the L-shaped plate 5. When the telescopic cylinder 2 is started to press and fix the wheel set bearing, it will drive the transmission block 4 to move, and the transmission block 4 will drive the calibration block 7 to move under the action of the connecting rod 6 to calibrate and fix the two ends of the wheel set bearing. During the calibration process, the expansion amplitude of the T-shaped block 9 will be adjusted according to the diameter size of the wheel set bearing, so that the wheel set bearing of different sizes can be stably fixed, and the shaking and deviation of the wheel set during rotation can be reduced.

[0031] The cleaning assembly 11 is arranged above the calibration frame 3.

[0032] In one embodiment of the present invention, the cleaning assembly 11 has a connecting ring 111 rotatably connected to the outside of the calibration frame 3. A connecting frame 112 is connected above the connecting ring 111. An adjusting rod 113 is slidably connected to the connecting frame 112. A hollow screw 114 is rotatably connected to the adjusting rod 113. A fixing rod 115 is provided on the inner side of the hollow screw 114. A rotating groove is opened on the inner side of the hollow screw 114. A circular protrusion is provided at the bottom end of the fixing rod 115, and the circular protrusion is located in the rotating groove of the hollow screw 114. A mounting block 116 is threadedly connected to the bottom of the hollow screw 114. A cleaning brush 117 is connected to the bottom of the mounting block 116. By providing the cleaning brush 117, dust and impurities on the surface of the wheelset can be cleaned, thereby avoiding the accumulation of dust and impurities from affecting the dimensional detection data. During the upward movement of the calibration frame 3, the cleaning brush 117 will be driven to rise by double the amplitude, thereby cleaning dust and impurities on the surface of wheelsets of different sizes and improving the accuracy of the wheelset detection data.

[0033] In one embodiment of the present invention, a first spring is connected to the inner side of the calibration block 7, and the other end of the first spring is connected to the T-shaped block 9. A guide rod is also connected to the inner side of the calibration block 7, and the guide rod passes through the central hole of the first spring and is slidably connected to the T-shaped block 9. By providing the first spring, the T-shaped block 9 can quickly return to its initial position, and by providing the guide rod, the first spring can be limited, reducing the occurrence of deformation and misalignment of the first spring.

[0034] In one embodiment of the present invention, a second spring is connected to the inner side of the calibration frame 3, and the other end of the second spring is connected to the transmission block 4. A connecting rod is also connected to the inner side of the calibration frame 3, and the connecting rod passes through the central hole of the second spring and is slidably connected to the transmission block 4. By providing the second spring, the transmission block 4 can be quickly pushed back to the initial position to fix the wheelset bearing, and the connecting rod limits the transmission block 4, thereby improving the stability of the transmission block 4 during the movement process.

[0035] In one embodiment of the present invention, a limiting rod is connected to the inner side of the calibration frame 3, and the limiting rod is slidably connected to the calibration block 7. By setting the limiting rod, the calibration block 7 can be limited, thereby improving the stability of the calibration block 7 during movement. A sliding telescopic rod is connected to the bottom inner side of the main body 1 of the testing machine, and the bottom end of the sliding telescopic rod is connected to the adjusting rod 113. By setting the sliding telescopic rod, the adjusting rod 113 is limited, thereby preventing the adjusting rod 113 from rotating due to the influence of the connecting frame 112.

[0036] In one embodiment of the present invention, a mounting rod is connected to the bottom of the hollow screw 114, and the mounting rod is slidably connected to the mounting block 116. By setting the mounting rod to limit the mounting block 116, the situation where the mounting block 116 rotates due to the influence of the hollow screw 114 is reduced, and the stability of the mounting block 116 during vertical movement is improved.

[0037] As an embodiment of the present application, the four groups of T-shaped blocks 9 are provided with curved surfaces on the inner sides, and the curved surfaces are provided with anti-skid rubber, which improves the fixing effect of the T-shaped blocks 9 on the wheel set bearings and reduces the sliding of the wheel set during the inspection process.

[0038] As an embodiment of the present application, the fixed rod 115 is connected to the bottom of the detection machine body 1, and is made of high-strength steel material to avoid breakage of the circular protrusions of the fixed rod 115 during transmission.

[0039] Working principle: when the wheel set needs to be detected, the lifting device of the wheel set track is started to lift the wheel set bearing to the position of the transmission block 4, and then the telescopic cylinder 2 is started to push the calibration frame 3 to move, the movement of the calibration frame 3 drives the movement of the transmission block 4, the movement of the transmission block 4 gradually fits the wheel set bearing, and the transmission block 4 stops moving after fitting the inclined wheel set bearing, the inclined bearing will fit the T-shaped block 9 and the calibration block 7 during the process of being pressed and inclined, so as to stop further inclination, and the calibration frame 3 will still move after the transmission block 4 stops moving, because the L-shaped plate 5 is hinged to one end of the connecting rod 6, and the other end of the connecting rod 6 is hinged to the calibration block 7, and the calibration block 7 is slidingly connected to the calibration frame 3, so that the four calibration blocks 7 will move to the center position during the movement of the calibration frame 3, and the calibration block 7 will calibrate the position of the wheel set bearing during the movement, and the wheel set bearing center shaft will no longer be offset by fixing the wheel set bearing by the calibration block 7 and the T-shaped block 9, so as to improve the accuracy of the wheel set detection data.

[0040] Secondly, the calibration block 7 will move during the movement of the calibration frame 3, and because the calibration block 7 is connected to the T-shaped block 9 through the transmission telescopic rod 10, the T-shaped block 9 will be received during the movement of the calibration block 7, when the wheel set bearing size is larger, the calibration block 7 will fit the wheel set in advance to stop the T-shaped block 9 from being received, so as to avoid the situation that the wheel set is not fixed stably caused by the small fitting area of the calibration block 7 and the bearing, and the adjustable T-shaped block 9 avoids the situation that the T-shaped block 9 fits the wheel set in advance when the bearing size is small, which causes the wheel set bearing to be unable to fit the transmission block 4.

[0041] Finally, when detecting wheelsets of different sizes, the connecting ring 111 moves vertically during the lifting of the calibration frame 3, the connecting ring 111 drives the connecting frame 112 to move, the connecting frame 112 drives the adjusting rod 113 to move, and the adjusting rod 113 drives the hollow screw 114 to move. Since the fixed rod 115 is fixedly connected to the inner side of the detection machine body 1, and the circular protrusion of the fixed rod 115 is located in the rotating groove of the hollow screw 114, the hollow screw 114 rotates during the vertical movement due to the influence of the rotating groove and the circular protrusion. Since the hollow screw 114 is threadedly connected with the mounting block 116, and the mounting block 116 is slidingly connected with the mounting rod, the rotation of the hollow screw 114 drives the mounting block 116 to move vertically, and the vertical movement distance of the mounting block 116 is the same as the lifting height of the calibration frame 3, so that the cleaning brush 117 is located above the wheels of the wheelset of different sizes and is attached to the wheels. During the rotation detection of the wheelset, the cleaning brush 117 cleans the dust and impurities on the surface of the wheels of the wheelset, reducing the influence of dust and impurities accumulation on the detection data.
