Description

Technical Field

[0001] This utility model relates to the technical field of welding, and in particular to a welding and positioning device for underground transportation track components in coal mines. Background Technology

[0002] Underground mine tracks are typically constructed from multiple sections of steel rail. The joints at both ends of the rails need to be welded together to prevent misalignment or loosening due to transport vibrations, ensuring smooth train or mine car operation. During rail welding, the two rail sections need to be secured to ensure stability during the welding process. Currently, one worker holds the rail section to be welded while another uses a welding torch to weld the joint. However, this method has several drawbacks: relying on manual support is labor-intensive and unstable; furthermore, sparks during welding can injure the worker's hands, making it inconvenient to use. Therefore, a positioning device for securing the rails is needed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a welding and positioning device for underground coal mine transport track components that can clamp and fix track A and track B without requiring workers to hold them by hand, saving labor, and is convenient, safe and reliable.

[0004] This utility model discloses a welding and positioning device for underground coal mine transport rail components, comprising a fixed frame, a fixed plate, a sliding plate, two sets of clamping mechanisms, and a moving mechanism. The fixed plate is fixedly installed on the left side of the fixed frame, and the sliding plate is slidably installed on the fixed frame. The moving mechanism is used to move the sliding plate left and right. The two sets of clamping mechanisms are respectively installed at the lower ends of the fixed plate and the sliding plate. In underground operations, when rail A and rail B need to be spliced ​​and fixed together, the clamping mechanism below the fixed plate clamps and fixes it to rail A. Then, the clamping mechanism below the sliding plate clamps it to rail B. The moving mechanism moves the sliding plate to the left, thereby causing the clamping mechanism below the sliding plate to move rail B to the left, bringing the end faces of rail A and rail B together. Then, workers use a welding torch to weld and fix the joint between rail A and rail B. This device can clamp and fix rail A and rail B without requiring workers to manually fix them, saving labor, and is convenient to use with high safety and reliability.

[0005] Preferably, the clamping mechanism includes a vertical plate, a slide rail, two sets of sliding blocks, a lead screw, and two sets of clamping plates. The slide rail is fixedly mounted on the vertical plate. The two sets of sliding blocks are slidably mounted on the front and rear parts of the slide rail, respectively. The lead screw is rotatably mounted on the vertical plate. The front and rear parts of the lead screw are respectively provided with threads of opposite directions. The two sets of sliding blocks are screwed onto the front and rear parts of the lead screw, respectively. The two sets of clamping plates are fixedly mounted on the two sets of sliding blocks. The vertical plates on the two clamping mechanisms are respectively fixedly mounted on the lower ends of the fixed plate and the sliding plate. When clamping and fixing track A or track B, taking track A as an example, track A is positioned between the two sets of clamping plates. Then, the lead screw is rotated. The rotating lead screw causes the two sets of sliding blocks to move the two sets of clamping plates closer to each other, thereby clamping and fixing track A from front to back, which facilitates the clamping and fixing of the track.

[0006] Preferably, the moving mechanism includes a hydraulic cylinder and a push rod. The hydraulic cylinder is fixedly installed on the right end of the fixed frame, and the push rod is slidably installed on the fixed frame. The right end of the push rod is connected to the power output end of the hydraulic cylinder, and the left end of the push rod is fixedly connected to the sliding plate. When it is necessary to connect rail A and rail B, the hydraulic cylinder is opened. The hydraulic cylinder, through the push rod, causes the sliding plate to drive the clamping mechanism on the right side and rail B to move to the left, so that rail B moves to the left to connect with rail A. This facilitates the connection and fixing of rail A and rail B.

[0007] Preferably, it also includes a gas concentration detector, which is fixedly installed on a fixed frame; during the welding process, the gas concentration around the welding process is monitored by the gas concentration detector, which improves the safety of the welding process.

[0008] Preferably, it also includes a handle, which is fixedly installed on the fixed frame; the above configuration facilitates the handling of the fixed frame by the staff.

[0009] Preferably, the surface of the clamping plate is provided with a high-temperature resistant coating and anti-slip texture; the above-mentioned configuration improves the high-temperature resistance of the clamping plate and at the same time improves the stability of the clamping plate in clamping rails A and B.

[0010] Preferably, the fixing frame is made of lightweight alloy steel; this design reduces the weight of the fixing frame and facilitates its movement.

[0011] Compared with the prior art, the advantages of this utility model are: it can clamp and fix track A and track B without the need for workers to fix track A and track B by hand, saving labor, making it convenient to use, and ensuring high safety and reliability. Attached Figure Description

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] Example 1

[0020] like Figures 1 to 5 The coal mine underground transport track component welding and positioning device of this utility model includes a fixed frame 1, a fixed plate 2, a sliding plate 3, two sets of clamping mechanisms, and a moving mechanism. The fixed plate 2 is fixedly installed on the left side of the fixed frame 1, and the sliding plate 3 is slidably installed on the fixed frame 1. The moving mechanism is used to move the sliding plate 3 left and right. The two sets of clamping mechanisms are respectively installed at the lower ends of the fixed plate 2 and the sliding plate 3. In the underground, when it is necessary to splice and fix the track A13 and track B14 together, the clamping mechanism below the fixed plate 2 is clamped and fixed on the track A13, and then the lower part of the sliding plate 3 is clamped and fixed. The clamping mechanism clamps onto the track B14, and the sliding plate 3 moves to the left via the moving mechanism. This causes the clamping mechanism below the sliding plate 3 to move the track B14 to the left, bringing the end faces of the track A13 and track B14 together. Then, the worker can use a welding torch to weld and fix the joint between the track A13 and track B14. This mechanism can clamp and fix the track A13 and track B14 without the need for workers to manually fix them, saving labor, making it convenient to use, and ensuring high safety and reliability.

[0021] like Figure 1 and Figure 3The clamping mechanism includes a vertical plate 4, a slide rail 5, two sets of sliding blocks 6, a lead screw 7, and two sets of clamping plates 8. The slide rail 5 is fixedly installed on the vertical plate 4. The two sets of sliding blocks 6 are slidably installed on the front and rear parts of the slide rail 5, respectively. The lead screw 7 is rotatably installed on the vertical plate 4. The front and rear parts of the lead screw 7 are respectively provided with threads of opposite directions. The two sets of sliding blocks 6 are screwed to the front and rear parts of the lead screw 7, respectively. The two sets of clamping plates 8 are fixedly installed on the two sets of sliding blocks 6, respectively. The vertical plate 4 on the two clamping mechanisms is fixedly installed on the lower end of the fixed plate 2 and the sliding plate 3, respectively. When clamping and fixing the track A13 or the track B14, taking the track A13 as an example, the track A13 is positioned between the two sets of clamping plates 8. Then, the lead screw 7 is rotated. The rotating lead screw 7 causes the two sets of sliding blocks 6 to move the two sets of clamping plates 8 closer to each other, thereby clamping and fixing the track A13 from front to back, which facilitates the clamping and fixing of the track.

[0022] like Figure 1 The moving mechanism includes a hydraulic cylinder 9 and a push rod 10. The hydraulic cylinder 9 is fixedly installed on the right end of the fixed frame 1, and the push rod 10 is slidably installed on the fixed frame 1. The right end of the push rod 10 is connected to the power output end of the hydraulic cylinder 9, and the left end of the push rod 10 is fixedly connected to the sliding plate 3. When it is necessary to connect the rails A13 and B14, the hydraulic cylinder 9 is opened. The hydraulic cylinder 9, through the push rod 10, causes the sliding plate 3 to drive the clamping mechanism on the right side and the rail B14 to move to the left, so that the rail B14 moves to the left until it connects with the rail A13. This facilitates the connection and fixing of the rails A13 and B14.

[0023] like Figure 1 It also includes a gas concentration detector 11, which is fixedly installed on the fixed frame 1; during the welding process, the gas concentration around the welding process is monitored by the gas concentration detector 11, which improves the safety of the welding process.

[0024] It also includes a handle 12, which is fixedly installed on the fixed frame 1; the above settings facilitate the staff to pick up and put down the fixed frame 1.

[0025] The surface of the clamping plate 8 is provided with a high-temperature resistant coating and anti-slip texture; through the above-mentioned design, the high-temperature resistance of the clamping plate 8 is improved, and the stability of the clamping plate 8 in clamping the rails A13 and B14 is also improved.

[0026] Example 2

[0027] Based on Example 1, the fixed frame 1 is made of lightweight alloy steel; through the above-mentioned arrangement, the weight of the fixed frame 1 is reduced, making it easier to move the fixed frame 1.

[0028] The slide rail 5, hydraulic cylinder 9, gas concentration detector 11, and handle 12 of the coal mine underground transport track welding and positioning device of this utility model are all purchased from the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from technical personnel in this field.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
