Description

Technical Field

[0001] This invention belongs to the field of railway maintenance technology, specifically relating to a multi-functional anchor-modification hot melt machine for railway maintenance. Background Technology

[0002] The track anchoring hot-melt machine is a high-efficiency device specifically designed for the maintenance of railway track anchoring systems. It is mainly used for the rapid and non-destructive replacement of pre-embedded sleeves (nylon sleeves) in concrete sleepers or track slabs. Its core function is to soften the inner wall of the sleeve through hot-melt technology, and in conjunction with a mechanical structure, to achieve precise removal and replacement of the sleeve, significantly improving work efficiency and reducing the risk of damage to the track structure.

[0003] When replacing the nylon sleeves on the surface of railway sleepers using a hot melt machine at railway track maintenance sites, the hot melt rod must first be inserted into the nylon sleeve. Because the head of the hot melt rod is designed with a specific shape of protrusion, after insertion and heating, these protrusions will leave clear marks matching the protrusions on the softened inner wall of the nylon sleeve. Then, a special removal device is used to align and insert the rod into the hole of the nylon sleeve again, and the nylon sleeve is removed by rotation. The whole operation process is not simple, and if multiple sleepers are to be maintained, the equipment needs to be changed multiple times, making the operation cumbersome. Summary of the Invention

[0012] Preferably, the output end of the second electric push rod is provided with a connecting rod, the bottom end of the connecting rod is fixedly connected to the hot melt rod, the bottom end of the hot melt rod is fixedly connected to a first heat insulation plate, the bottom surface of the first heat insulation plate is fixedly connected to a first inclined block, the surface of the extraction head is provided with a rectangular groove, the extraction head is slidably connected to a rectangular plate by means of the rectangular groove, the two ends of the first spring are fixedly connected to the inner wall of the rectangular plate and the rectangular groove respectively, and the top of the extraction head is fixedly connected to a second inclined block.

[0013] Preferably, the inner wall of the rectangular groove is fixedly connected to two limiting rods, and the ends of the two limiting rods near the sliding block are slidably inserted into the surface of the rectangular plate.

[0014] Preferably, a support column is fixedly connected to the bottom of the extraction head, a roller assembly is installed at the bottom of the support column, a second heat insulation plate is fixedly connected to the output end of the second electric push rod, the top end of the connecting rod is fixedly connected to the bottom surface of the second heat insulation plate, and a conical rod is fixedly connected to the arc surface of the connecting rod.

[0015] Preferably, the arc surface of the slide bar is fitted with a second spring, and the two ends of the second spring are fixedly connected to the fixing plate and the protrusion, respectively.

[0016] Preferably, the sliding block has a recessed hole inside and an insertion hole on its surface.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention integrates the extraction head and the hot melt rod inside the sleeve. With the help of the elastic force of the first spring, the extraction head can immediately fill the center position of the sleeve after the hot melt rod moves upward, achieving the function of quickly changing the position of the hot melt rod and the extraction head. The magnetic force between the first and second inclined blocks can stabilize them together. The extraction head is driven to move downward by the second electric push rod, and the micro motor drives the sleeve to rotate the extraction head, achieving the effect of replacing the nylon sleeve on the sleeper. This avoids the need to change equipment to remove the nylon sleeve after the hot melt rod has finished its work, simplifying the operation process. Only the hot melt rod needs to be moved up and down, eliminating the need for frequent equipment changes and making the operation more convenient.

[0020] 2. After the extraction head completes the removal work and moves upward, the second spring helps to stabilize the position of the extraction head. The first inclined block presses against the second inclined block to move the extraction head to the side, thus not affecting the normal downward movement of the hot melt rod. Furthermore, under the pressure of the insert plate against the pressure plate, the fixing of the extraction head position is automatically released after the extraction head moves to the appropriate position, allowing the extraction head to return to its initial state for subsequent work.

[0021] 3. The present invention can adjust the position of the clamping plate by driving the threaded rod, and cooperate with the positioning plate to better adapt to the shape of the rail, thereby positioning the hot melt rod. This makes the path of the operator vertical and less prone to deviation. Furthermore, under the electric drive of the first electric push rod, it can minimize the possibility of insufficient manual downward pressure and positioning deviation. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Reference Figures 1-11 As shown, the present invention provides a multi-functional anchor-modification hot melt machine for railway maintenance, including a machine body 1, a handrail 101 installed on the surface of the machine body 1, and a round tube 102, which is fixedly installed at the bottom of the machine body 1.

[0039] The device body 1 is an existing device. An operation knob is installed on the surface of the device body 1, which can control the start of the device body 1. It will not be described in detail here.

[0040] In an optional embodiment: a positioning mechanism 2 includes a mounting plate 201 fixedly connected to the arc surface of the circular tube 102. A first electric push rod 202 is mounted on the end face of the mounting plate 201. A positioning plate 206 is provided below the mounting plate 201. A threaded rod 207 is rotatably connected to the surface of the positioning plate 206. A threaded sleeve 208 is threadedly connected to the arc surface of the threaded rod 207. Both sides of the threaded sleeve 208 are provided with clamping plates 209. A connecting plate 203 is fixedly connected to the output end of the first electric push rod 202. A guide rod 204 is fixedly connected to the bottom surface of the connecting plate 203. A fixing sleeve 205 is slidably installed on the arc surface of rod 204. The fixing sleeve 205 is fixedly connected to the surface of mounting plate 201. Positioning plate 206 is fixedly connected to the bottom end of guide rod 204. A slide rail 210 is fixedly connected to the surface of positioning plate 206. A slider 211 is slidably connected to the two inner walls of slide rail 210. The two sliders 211 are fixedly connected to two clamping plates 209 respectively. The two clamping plates 209 are fixedly connected to the arc surface of threaded sleeve 208. A handle 212 is fixedly connected to the surface of threaded rod 207. A rail model is provided between the two clamping plates 209 and positioning plate 206.

[0041] It should be noted that there is a sliding groove on both sides of the slide rail 210, which allows two sliders 211 to slide respectively. That is, when the clamping plate 209 moves, the sliders 211 will slide. The arc surface of the threaded rod 207 has no threads at the connection with the positioning plate 206.

[0042] In an optional embodiment: a lifting mechanism 3, the lifting mechanism 3 includes a micro motor 301 installed inside a circular tube 102, the output end of the micro motor 301 is fixedly connected to a sleeve 302, a hot melt rod 103 is installed at the bottom of the sleeve 302, a second electric push rod 303 and a take-out head 310 are provided on the inner wall of the sleeve 302, a track frame 307 is fixedly connected to the inner wall of the sleeve 302, a sliding block 308 is slidably connected to the inner wall of the track frame 307, a rectangular plate 309 is fixedly connected to the surface of the sliding block 308, the take-out head 310 is slidably connected to the surface of the rectangular plate 309, and a first spring 313 is provided between the take-out head 310 and the rectangular plate 309;

[0043] In this embodiment, the second electric push rod 303 is fixedly connected to the top wall inside the sleeve 302. The hot melt rod 103 needs to be heated by electricity, which is existing technology and will not be described in detail here. The extraction head 310 is sized to match the hot melt rod 103 but the lengths of the two are different, which is existing technology. It is responsible for removing the nylon sleeve from the surface of the sleeper and will not be described in detail here. A through hole is provided at the bottom of the sleeve 302. The size of the through hole is matched to the size of the hot melt rod 103 and the extraction head 310. The second electric push rod 303 can be automatically locked when closed.

[0044] The output end of the second electric push rod 303 is provided with a connecting rod 304. The bottom end of the connecting rod 304 is fixedly connected to the hot melt rod 103. The bottom end of the hot melt rod 103 is fixedly connected to the first heat insulation plate 305. The bottom surface of the first heat insulation plate 305 is fixedly connected to the first inclined block 306. The surface of the extraction head 310 is provided with a rectangular groove 312. The extraction head 310 is slidably connected to the rectangular plate 309 by means of the rectangular groove 312. The two ends of the first spring 313 are fixedly connected to the inner wall of the rectangular plate 309 and the rectangular groove 312 respectively. The top of the extraction head 310 is fixedly connected to the second inclined block 311.

[0045] It should be noted that the connecting rod 304 is made of heat-insulating material, which does not easily absorb heat from the hot melt rod 103. The first heat insulation plate 305 is also made of heat-insulating material, which serves to prevent heat from the hot melt rod 103 from being transferred to the first inclined block 306. The second inclined block 311 is an electromagnet, which becomes magnetic when energized. The first inclined block 306 is made of iron material, which can attract the second inclined block 311 when energized. The cross-sectional shape of both the first inclined block 306 and the second inclined block 311 is triangular, so that when the two are not attracted together, the second inclined block 311 can slide when the first inclined block 306 presses against it.

[0046] In an optional embodiment, two limiting rods 314 are fixedly connected to the inner wall of the rectangular groove 312, and the ends of the two limiting rods 314 near the sliding block 308 are slidably inserted on the surface of the rectangular plate 309.

[0047] It should be noted that when the extraction head 310 moves, it will cause the limiting rod 314 to slide against the rectangular plate 309, which will limit and support the extraction head 310 and prevent the extraction head 310 from slipping off the rectangular plate 309 under the elastic force of the first spring 313.

[0048] In an optional embodiment: a support column 315 is fixedly connected to the bottom of the take-out head 310, a roller assembly 316 is installed at the bottom of the support column 315, a second heat insulation plate 317 is fixedly connected to the output end of the second electric push rod 303, the top end of the connecting rod 304 is fixedly connected to the bottom surface of the second heat insulation plate 317, and a conical rod 318 is fixedly connected to the arc surface of the connecting rod 304.

[0049] It should be noted that in the initial state, such as Figure 3 As shown, the first spring 313 is in a compressed state at this time, and the roller assembly 316 contacts the inner bottom wall of the sleeve 302, which reduces the friction when the extraction head 310 moves. The roller assembly 316 consists of wheels and a rotating shaft, which is existing technology and will not be described in detail here. The conical rod 318 is made of heat-insulating material, which plays a role in heat insulation and does not easily absorb heat from the hot melt rod 103. It facilitates the extraction head 310 to retract to one side when the hot melt rod 103 moves upward in the initial state.

[0050] After the hot melt rod 103 moves upward, the take-out head 310 will spring back under the action of the first spring 313 and return to the center position of the sleeve 302. That is, when the first spring 313 is relaxed, the take-out head 310 is located at the center of the sleeve 302.

[0051] In an optional embodiment: auxiliary mechanism 4, the auxiliary mechanism 4 includes a circular hole 401 formed on the surface of the sliding block 308, a fixing plate 404 fixedly connected to the surface of the sliding block 308, a sliding rod 405 slidably inserted into the surface of the fixing plate 404, and a protrusion 406 fixedly connected to one end of the sliding rod 405 near the sliding block 308.

[0052] The arc surface of the slide bar 405 is fitted with a second spring 407, and the two ends of the second spring 407 are fixedly connected to the fixing plate 404 and the protrusion 406 respectively.

[0053] It should be noted that the end of the protrusion 406 furthest from the second spring 407 is hemispherical, meaning the protrusion 406 consists of two parts: a hemispherical front end and a cylindrical rear end. When the sliding block 308 moves upward and abuts the protrusion 406, it contacts the cylindrical part of the protrusion 406. Because the top of the sliding block 308 is chamfered, the protrusion 406 can move. Furthermore, when the protrusion 406 coincides with the circular hole 401 and the second spring 407 rebounds, the protrusion 406 inserts into the circular hole 401, and the contact point is also on the protrusion 406. The cylindrical part contacts the wall of the circular hole 401. Therefore, after the second inclined block 311 loses power and loses its magnetic force, when the first inclined block 306 presses down on the second inclined block 311, the protrusion 406 will not move, that is, the position of the sliding block 308 will not move, thus stabilizing the position of the sliding block 308. So when the first inclined block 306 presses down on the second inclined block 311, the sliding block 308 will not move, and the extraction head 310 will move laterally, achieving the effect of seamlessly switching the positions of the hot melt rod 103 and the extraction head 310.

[0054] In an optional embodiment: a recessed hole 403 is provided inside the sliding block 308, and an insertion hole 402 is provided on the surface of the sliding block 308. An insertion plate 408 adapted to the insertion hole 402 is fixedly connected to the side of the take-out head 310 near the sliding block 308. A rotating rod 409 is rotatably connected to the inner wall of the recessed hole 403. A connecting sleeve 410 is fixedly connected to the arc surface of the rotating rod 409. A pressure plate 411 is fixedly connected to the surface of the connecting sleeve 410. A torsion spring 412 is sleeved on the arc surface of the rotating rod 409. The two ends of the torsion spring 412 are fixedly connected to the rotating rod 409 and the inner wall of the recessed hole 403, respectively.

[0055] It should be noted that after the second inclined block 311 loses its magnetic force due to power de-energization, when the first inclined block 306 presses down on the second inclined block 311, the sliding block 308 does not move. The extraction head 310 will move laterally, causing the insertion plate 408 to be inserted into the insertion hole 402. The insertion plate 408 first presses against the pressure plate 411, causing the pressure plate 411 to rotate. The torsion spring 412 is in a torsional state, and the upper end of the pressure plate 411 will rotate towards the protrusion 406, pressing the protrusion 406 and causing the protrusion 406 to exit through the round hole 402. As the hot melt rod 103 moves out, it also passes the maximum distance of the compression with the second inclined block 311. This means the removal head 310 will no longer move towards the insertion hole 402. Finally, the hot melt rod 103 moves back to the bottom of the sleeve 302. Because the protrusion 406 slides out of the round hole 401, the sliding block 308 slides downwards under gravity. Finally, the roller assembly 316 at the bottom of the support column 315 contacts the bottom wall of the sleeve 302, returning to its initial position. Figure 3 As shown, this is to facilitate subsequent work.

[0056] The working principle of this invention is as follows: During use, the hot melt rod 103 is inserted into the nylon sleeve on the surface of the sleeper. The first electric push rod 202 is activated via an external power controller, causing the positioning plate 206 to move downwards. After moving to a suitable height, the positioning plate 206 adheres to the rail surface. By turning the threaded rod 207, the two clamping plates 209 move closer to the rail until they are pressed against the rail surface. Then, the device body 1 is activated via the external power controller to heat the hot melt rod 103. After heating to a suitable temperature, the protruding part on the surface of the hot melt rod 103 leaves an imprint on the inner wall of the nylon sleeve on the sleeper. During this process, the operator needs to press down on the device body 1 to ensure the hot melt rod 103 is inserted deeply enough. The second electric push rod 303 is activated via the external power controller to lower the hot melt rod 103. After the hot melt is complete, the second electric push rod 303 is activated again to raise the hot melt rod 103. When the height of the hot melt rod 103 exceeds the removal head 310... At this point, the first spring 313 rebounds, and the extraction head 310 slides on the surface of the rectangular plate 309. Ultimately, the extraction head 310 will be at the center of the sleeve 302 and below the hot melt rod 103, with the second inclined block 311 adhering to the surface of the first inclined block 306. Then, by energizing the second inclined block 311 via an external power controller, the second inclined block 311 will have a magnetic force and attract to the first inclined block 306. At this point, the second electric push rod 303 is activated again, causing the hot melt rod 103 to move downwards. The removal head 310 will move down together until it is in the nylon sleeve on the surface of the sleeper and coincides with the mark of the heat fusion point in the nylon sleeve on the surface of the sleeper. Then, the micro motor 301 is started by the external power controller, which drives the sleeve 302 to rotate. The removal head 310 will then rotate in the nylon sleeve on the surface of the sleeper and drive the nylon sleeve on the surface of the sleeper to rotate. The second electric push rod 303 will drive the heat fusion rod 103 to move up, so as to remove the nylon sleeve on the surface of the sleeper.

[0057] After removing the nylon sleeve from the sleeper surface from the extraction head 310, the second electric push rod 303 is activated to move the hot melt rod 103 upwards, causing the extraction head 310 to move. As the extraction head 310 moves, the sliding block 308 slides along the inner wall of the track frame 307. When the top of the sliding block 308 reaches the protrusion 406, the protrusion 406 is compressed, causing the sliding rod 405 to move away from the sliding block 308. At this time, the second spring 407 is compressed, and the sliding block 308 continues to move. Move until the protrusion 406 aligns with the circular hole 401. The second spring 407 returns, inserting the protrusion 406 into the circular hole 401 and stabilizing the position of the sliding block 308, which in turn stabilizes the position of the extraction head 310. At this point, the second inclined block 311 is de-energized by the external power controller, losing its magnetic force. The second inclined block 311 and the first inclined block 306 will no longer attract each other. Then, the output shaft of the second electric push rod 303 moves downward, causing the first inclined block 306 to press against the second inclined block. 311. When the second inclined block 311 is squeezed, it causes the insert plate 408 to move closer to the insertion hole 402. At this time, the first spring 313 is in a compressed state. When the insert plate 408 is inserted into the insertion hole 402, the insert plate 408 will squeeze the pressure plate 411, causing the pressure plate 411 to rotate. The torsion spring 412 is in a torsional state, and the upper end of the pressure plate 411 will rotate closer to the protrusion 406, squeezing the protrusion 406 and causing the protrusion 406 to move out of the round hole 401. At this time, the heat melt... Once the rod 103 has passed the maximum distance of compression with the second inclined block 311, the extraction head 310 will no longer move towards the insertion hole 402. Finally, the hot melt rod 103 moves back to the bottom of the sleeve 302. As the protrusion 406 slides out of the round hole 401, the sliding block 308 will slide downward under the action of gravity. Finally, the roller assembly 316 at the bottom of the support column 315 will contact the bottom wall of the sleeve 302 and return to the initial position, facilitating subsequent work.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
