[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figure 1-6 As shown, this utility model provides a technical solution: a train brake beam maintenance device, comprising:

[0035] Fixture 1;

[0036] The multi-range clamping assembly 2 includes a fixed frame 29 fixedly connected within the fixed frame 1, a piston 28 slidably connected to the fixed frame 29, an inner slide rod 21 fixedly connected to the piston 28 via a transmission rod 216, a turntable 25 slidably connected to the inner slide rod 21, a base plate 23 slidably connected to the turntable 25, and the inner slide rod 21 slidably connected to the base plate 23. A telescopic rod 210 is fixedly connected to the fixed frame 29, a vertical slide rod 27 is fixedly connected to the telescopic rod 210, a locking rod 211 is fixedly connected to the vertical slide rod 27, a transverse rod 212 slidably connected to the locking rod 211, a lead screw 215 is connected to the transverse rod 212, and a connecting plate 213 is threadedly connected to the lead screw 215. An installation frame 4 is slidably connected to the fixed frame 1, and an assembly frame 42 is fixedly connected to the installation frame 4.

[0037] In this invention, the turntable 25 is driven to rotate by a motor on the third rotating shaft 26, which in turn drives the base plate 23 to swing via the second rotating shaft 24. The mechanical linkage between the inner slide rod 21 and the transmission rod 216 pushes the piston 28 to compress the air pressure inside the fixed frame 29, causing the three-section rubber telescopic rod 210 with a sealing ring to extend and retract vertically. Simultaneously, the vertical slide rod 27 drives the locking rod 211 to pass through the fixed frame 1 and abut against the connecting frame 3, achieving position locking and adjustment of the series plate 213 and the lead screw 215 assembly. Based on this, the motor of the lead screw 215 drives the reverse-threaded series plate 213 to complete the horizontal clamping action. The key advantage of this transmission design is... The position of the lead screw 215 can be flexibly adjusted through the cooperation of the locking rod 211 and the connecting frame 3, breaking the limitation of the fixed position of the lead screw 215 in traditional equipment. When there are differences in the size of the brake beam, the positioning height of the locking rod 211 can be adjusted by the pneumatic drive telescopic rod 210 without disassembling the parts, thereby changing the working position of the lead screw 215 and the series plate 213, realizing the dynamic adaptation of the clamping fulcrum. With the lateral extension and retraction of the lead screw 215 itself, it is compatible with the size differences of brake beams of most current models, and solves the problems of narrow adaptation range and cumbersome adjustment steps caused by the fixed position of the lead screw 215 in traditional equipment.

[0038] Furthermore, such as Figures 1 to 6 As shown, a third rotating shaft 26 is fixedly connected to the turntable 25. The side of the third rotating shaft 26 away from the turntable 25 is fixedly connected to the bottom of the fixing frame 1. A mounting column 41 is fixedly connected to the bottom of the mounting frame 4. A connecting frame 3 is fixedly connected to the fixing frame 1. In use, the third rotating shaft 26 is fixedly connected to the turntable 25, which facilitates the rotation of the turntable 25 at the bottom of the fixing frame 1.

[0039] like Figure 2 as well as Figure 6As shown, a second rotating shaft 24 is fixedly connected to the base plate 23. The side of the second rotating shaft 24 away from the base plate 23 is rotatably connected to the turntable 25. A first rotating shaft 22 is rotatably connected to the base plate 23. The side of the first rotating shaft 22 away from the third rotating shaft 26 is rotatably connected to the inner slide rod 21. By fixing the second rotating shaft 24 and the first rotating shaft 22 to the base plate 23, the connection between the base plate 23, the turntable 25, and the inner slide rod 21 becomes more flexible.

[0040] like Figure 3 As shown, a guide rod 214 is fixedly connected to the fixed frame 1, and the inner slide rod 21 is slidably connected to the guide rod 214. By fixing the guide rod 214 to the fixed frame 1, the inner slide rod 21 is guided.

[0041] like Figure 1 , Figure 4 , Figure 5 As shown, a square frame is fixedly connected to the fixed frame 1, and the mounting frame 4 is slidably connected to the square frame on the fixed frame 1. By fixing the square frame to the fixed frame 1, it is convenient for workers to install the telescopic rod 210 in it later.

[0042] like Figure 2 As shown, there are two series plates 213. The two series plates 213 are threaded in opposite directions on the lead screw 215. A motor is installed on the third rotating shaft 26 away from the turntable 25. The motor on the third rotating shaft 26 is fixedly connected to the fixed frame 1. By setting two series plates 213, the internal threads of the two series plates 213 are opened in opposite directions, and the rectangular bottom slides on the horizontal rod 212 to avoid rotation.

[0043] like Figures 5 to 6 As shown, a motor is mounted on the lead screw 215. The side of the motor on the lead screw 215 away from the lead screw 215 is fixedly connected to the fixing frame 1. The lead screw 215 is driven by the motor mounted on the lead screw 215.

[0044] Working principle:

[0045] like Figure 1-6 As shown, when in use, first install the flaw detector (model: CTS-1010) on the assembly frame 42. When in use, place the brake beam on the fixed frame 1. The motor can be installed on the square frame on the fixed frame 1. Fix the output end of the motor to the mounting frame 4 to facilitate moving the mounting frame closer to the fixed frame 1.

[0046] By starting the motor on the third rotating shaft 26, the third rotating shaft 26 is rotated, which in turn causes the turntable 25 to rotate. The turntable 25 drives the base plate 23 to rotate via the second rotating shaft 24, which in turn causes the base plate 23 to push the inner slide rods 21 on both sides to slide inward. The inner slide rods 21 drive the transmission rod 216 to slide inward, which in turn drives the pistons 28 on both sides to slide inward. The pistons 28 compress the air pressure in the fixed frame 29, which causes the fixed frame 29 to supply air to the telescopic rod 210. The telescopic rod 210 (made of rubber material, set as three sections, with a sealing ring placed at the contact position between the outer wall of each layer and the upper layer from bottom to top) is driven to extend upward, which causes the vertical slide rod 27 to drive the locking rod 211 to insert upward on the fixed frame 1, abut against the connecting frame 3, and lock the series plate 213.

[0047] Starting the motor on the lead screw 215 will drive the lead screw 215 to rotate, causing the lead screw 215 to drive the connecting plates 213 on both sides to slide inward, thereby causing the connecting plates 213 to slide inward and clamp the maintenance device.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
