Description

Technical Field

[0001] The invention relates to the technical field of insertion and removal devices, in particular to a rigid contact network contact line quick insertion and removal device. Background Art

[0002] In urban rail transit's power supply system, the rigid catenary, a key transmission component, bears the crucial task of providing stable power to trains. With the rapid development of urban rail transit and the increasing frequency of train operations, higher requirements are being placed on the stability and reliability of the rigid catenary. However, over the long-term operation of rigid catenary systems, various factors can affect the performance of these systems, leading to frequent contact wire derailment failures.

[0003] Traditionally, when the contact wire of a rigid contact network becomes dislocated, workers typically use a wire-paying trolley to repair it. However, the existing trolley's structural design has several drawbacks. Its guide wheel and expansion wheel are integrated, making the trolley relatively heavy. During installation, at least two workers are required to coordinate with each other: one person laboriously holds the heavy trolley to mate with the busbar, while the other tightens the bolts on the guide wheel to secure it against the side of the busbar, thereby securing the trolley in place. This process is not only labor-intensive and inefficient, but also impacts the efficiency and timeliness of rigid contact network maintenance. Summary of the Invention

[0049] Compared with the prior art, the present invention has the following beneficial effects:

[0050] 1. The rotating seat is used as the main load-bearing component of the sliding mechanism, and the L-shaped frames at its four ends and the guide sleeves on both sides provide an installation basis for other components. The buckle on the L-shaped frame cooperates with the rubber block. By twisting the buckle, the rubber block can be made close to the outer wall of the bus, thereby achieving reliable limitation of the rotating seat and ensuring stable installation of the device on the bus. The square frame and the guide sleeve in the quick-plug mechanism are slidably connected, and the oblique block and the square groove are plugged in and matched, so that the expansion mechanism can be quickly installed and disassembled on the sliding mechanism, and can be operated by one person. Compared with the traditional installation method of the wire-paying trolley, the work efficiency is greatly improved. The handle is convenient for the staff to operate by hand, and the square groove, the slider and the square rod connecting them cooperate with each other. By pressing the slider, the oblique block and the square groove can be easily separated, which further improves the convenience of disassembly.

[0051] 2. By twisting the hexagonal block to drive the round rod to rotate, the sliding of the square plate two is achieved, and the expansion and contraction of the busbar jaws are accurately controlled. The operation is simple and flexible. Two sets of balls are arranged on the outer wall of the square plate two, which effectively reduces the contact area with the busbar jaws and reduces the friction during pushing, making it easier for the staff to push the device. Through the round rod two and the round roller one, when the jaws are clamped, the round roller one squeezes the insulating layer at the jaws and cooperates with the square plate two to ensure that the busbar jaws are tightly clamped with the insulating layer, thereby improving the electrical connection stability and safety of the contact network. It is fixed to the square plate one through the partition, which plays a role in precise positioning and limiting when installing the device, ensuring that the expansion mechanism is accurately installed on the busbar, thereby improving the accuracy and efficiency of installation.

[0052] 3. The rough surface at one end of the square cooperates with the handle 2 to firmly clamp the insulation layer and separate it from the jaws. The operation is simple and efficient. The square plate 3 can not only pick out the contact wire in the bus, but also clean the impurities in the bus during the reciprocating movement of the auxiliary mechanism. The de-line and cleaning functions are realized in one action, which greatly improves the de-line efficiency. When sending the contact wire back to the bus, the round roller 3 moves close to the outer wall of the insulation layer, preventing the insulation layer from being located outside when the expansion mechanism clamps and pushes, ensuring that the insulation layer is fully engaged with the jaws, and improving the safety and stability of the contact network.

[0066] The expansion mechanism 300 includes: a square plate 310, which is fixedly connected to the square frame 210. A round rod 311 is rotatably connected at both ends between the two square plates 310. The outer walls of the round rod 311 on both sides are provided with a threaded groove 312. Both ends of the round rod 311 are fixedly connected with a hexagonal block 313. The square plate 322 is screwed on the threaded groove 312 to expand and contract the jaws. There are two groups of balls 323, which are respectively provided on the outer wall of one side of the square plate 322 at one end and on the outer wall of the adjacent side. They can reduce the contact area with the bus jaws, reduce friction, and facilitate personnel pushing. There are two groups of round rods 320, which are respectively fixed to the two square plates. At both ends of the round rod 310, a round roller 321 is rotatably connected to the center of the round rod 320, which can squeeze the insulating layer at the jaws, and then cooperate with the square plate 322 to clamp the jaws so that the bus jaws are engaged with the insulating layer. The partition 330 is fixed on the square plate 310 and can play a positioning and limiting role during installation. The multi-stage rod 340 is provided with a group, which is fixed on the square plate 310. A group of multi-stage rods 340 can be extended and fixedly connected with a square rod 342 between one end, which can drive the auxiliary mechanism 400 to extend. The bolt 341 is screwed on the square plate 310 to squeeze the outer wall of the multi-stage rod 340 and limit the extendable part of the multi-stage rod 340.

[0067] The auxiliary mechanism 400 includes: a slide rail 410, which is fixedly connected to two square rods 342, a square block 411 is slidably inserted into the slide rail 410, a round roller 2 412 is rotated on the outer wall of the square block 411, a square groove 3 413 is opened inside the square block 411, a handle 2 414 is fixed to the bottom of the square block 411, a round hole is opened inside the handle 2 414, and is communicated with the inside of the square groove 3 413, a round rod 3 420 is slidably inserted into the round hole, a square plate 3 421 is fixed to one end of the round rod 3 420, and is slidably inserted into the inside of the square groove 3 413, which can pick out the contact line in the bus and clear out the garbage in the bus during the movement of the auxiliary mechanism 400, a square plate 422 is fixed to the other end of the round rod 3 420, and a T-shaped frame 440 is fixed to the slide rail 410. At the center, square grooves 445 are provided on both sides of one end of the T-shaped frame 440. The square grooves 445 are slidably plugged into the square plate 422. Two latches 444 are provided, which are respectively fixed on both sides of the T-shaped frame 440 and located above the square grooves 445. A group of guide sleeves 130 are provided, which are opened on the outer wall of one side of the slide rail 410. A U-shaped frame 431 is plugged between the two square holes 430. The outer wall of the U-shaped frame 431 is screwed together with a button 2 432. One end of the button 2 432 is rotatably connected to the slide rail 410. The spring 2 450 is fixed between the outer wall of the block 411 and the inner wall of the slide rail 410. The slide groove 441 is provided on the outer wall of the T-shaped frame 440. The L-shaped frame 2 442 is slidably plugged into the inside of the slide groove 441. The round roller 3 443 rotates at one end of the L-shaped frame 2 442.

[0068] Specifically, during operation, the rotating seat 110 in the sliding mechanism 100 is placed on the top plane of the bus, so that the L-shaped frame 120 is in contact with the side wall of the bus, and the staff twists the buckle 121 on the L-shaped frame 120. The rubber block 122, which is rotatably connected at one end of the buckle 121 and located in the guide groove of the L-shaped frame 120, will slide tightly against the side wall of the bus, thereby limiting the rotating seat 110. Then, the staff holds the handles 220 on both sides of the quick-plug mechanism 200 with both hands, picks up the expansion mechanism 300, and plugs the square frame 210 along the guide sleeve 130. When the square frame 210 slides to the specified position in the guide sleeve 130, the oblique block 214 fixedly connected at one end of the square rod 212 will be plugged into the square groove 131 in the guide sleeve 130. The expansion mechanism 300 is quickly limited on the sliding mechanism 100. At this time, the partition 330 on the inner wall of the square plate 1 310 is just against the chute port of the busbar, limiting the bottom of the expansion mechanism 300. The entire installation process can be completed by one person. After the installation is completed, the staff uses a wrench to twist the hexagonal block 313 to drive the round rod 1 311 to rotate. Since the threaded grooves 312 on the outer walls of both sides of the round rod 1 311 are screwed with the square plate 2 322, the round rod 1 311 will cause the square plate 2 322 to slide to one side when it rotates, squeezing the inner wall of one side of the busbar chute, thereby expanding the busbar jaws, twisting the bolt 341 to release the multi-stage rod 340 from the limit, and pushing the auxiliary mechanism 400 to move to the contact line and the insulating sleeve out of the groove. The staff holds the handle 2 414, The two handles 414 are brought together toward the middle, and the rough surface provided at one end of the block 411 will clamp the protruding insulating layer and deform the insulating layer, so that it is separated from the jaws. Then, the staff member presses the insulating layer outside the jaws with his fingers to move it downward, and releases the handle 414 with the other hand. The handle 414 is rebounded by the spring 450, so that the handle 414 returns to its original position and presses the insulating layer here to the bottom of the round roller 412. The staff member then holds the two handles 414 together toward the middle, so that the two round rollers 412 limit the insulating layer below. At the same time, the button 432 is twisted to move the U-shaped frame 431 toward the inside of the slide rail 410, close to the blocks 411 on both sides, and limit the blocks 411 to prevent separation. When the two square blocks 411 are separated, the two square blocks 411 are located inside the jaws near the inner walls on both sides. The staff pushes the round rod three 420 to move upward, driving the square plate three 421 inside the square groove three 413 to move upward. The square plate three 421 passes the contact line between the jaws and the interior. When the square plate three 421 is above the contact line, the staff rotates the round rod three 420 to drive the square plate three 421 to rotate so that the two square plates three 421 are at the same level. At this time, the square plate four 422 below the round rod three 420 is located just above the square groove four 445, and pushes the round rod three 420 to move downward so that the square plate four 422 enters the square groove four 445. When the square plate four 422 completely enters the square groove four 445, the inclined fixing pin of the latch 444 rebounds to limit the square plate four 422.When the round rod 3 420 moves down, it drives the square plate 3 421 to move down, and the contact wire inside the jaws can be taken out of the jaws together. After that, the staff holds the handle 2 414 and quickly drives the auxiliary mechanism 400 to move back and forth. During this period, the contact wire and the insulating layer within a certain range can be separated from the jaws by the limitation of the square plate 3 421 and the round roller 2 412. In the process of moving back and forth, the square plate 3 421 can push all the internal impurities out of the jaws. After completing the de-wire and cleaning, the staff cleans the outer wall of the jaws and evenly applies Conductive paste, push the dial of the plug 444, so that the fixing pin slides into the inside of the plug 444, release the limit of the square plate 422, take the square plate 422 out of the square slot 445, twist the button 2 432 to release the limit of the square block 411, and the block 411 is driven back to its original position by the rebound of the spring 2 450, releasing the limit on the contact line and the insulating layer. The staff pushes the insulating layer to the top of the round roller 2 412, and at the same time, pushes the L-shaped frame 2 442 to drive the round roller 3 443 to move upward to the two sides of the round roller 3 443. The groove is aligned with the round roller 2 412, and the handle 2 414 is held to bring the two blocks 411 together to connect the round roller 2 412 with the round groove of the round roller 3 443. The staff holds the handle 2 414 to push. At this time, the round roller 3 443 is tightly attached to the outer wall of the insulating layer. With the push, the contact line is sent back to the bus. After the return line is completed, the handle 2 414 is released, and the round roller 3 443 returns to its original position. The staff twists the buckle 121 to release the limit of the rotating seat 110, and uses a wrench to twist the hexagonal block 313 to make the square plate 2 322 Move toward the jaws, and make the ball bearing 323 contact the outer wall of the jaws. The staff member holds the handle 1 220 to drive the expansion mechanism 300 and the sliding mechanism 100 to move back and forth along the busbar. The round roller 1 321 sticks to the outer wall of the insulation layer, tightening the jaws and locking the insulation layer. Once completed, the staff member simply presses the slider 223 to move into the inside of the square groove 222, separating the inclined block 214 from the square groove 131, and quickly completes the disassembly of the expansion mechanism 300. Finally, remove the sliding mechanism 100 from the busbar.

[0069] Example 1

[0070] like Figure 3-6As shown, in this embodiment, the sliding mechanism 100 includes: two guide wheels 111, which are respectively rotated on the rotating shafts at both ends of the rotating seat 110 to drive the expansion mechanism 300 to move, a buckle 121, which is screwed on the L-shaped frame 120, and one end of the buckle 121 is located in the guide groove of the L-shaped frame 120 and is rotatably connected to a rubber block 122, and the rubber block 122 is slidably plugged into the guide groove of the L-shaped frame 120 to be close to the outer wall of the busbar to limit the sliding mechanism 100, and the quick-plug mechanism 200 includes: a square frame 210, which is slidably plugged into the inside of the guide sleeve 130, a square hole 211, which is opened on the outer wall of one side of the square frame 210 at one end, a square rod 212, which slides It is movably inserted into the square frame 210, and one end of the square rod 1 212 is fixedly connected to the inclined block 214. The inclined block 214 is slidably inserted into the square groove 131 through the square hole 1 211, and is used to quickly limit the expansion mechanism 300 on the sliding mechanism 100. The spring 1 213 is fixed between the inner wall of the square frame 210 and the outer wall of the square rod 1 212. The handle 1 220 is fixed on the outer wall of one side of the square frame 210. The handle 1 220 is provided with a square groove 222. The slider 223 slides inside the square groove 222. The square rod 221 is fixed between the slider 223 and the square rod 1 212, which can facilitate personnel operation and quickly separate the sliding mechanism 100 and the expansion mechanism 300 to complete the disassembly work.

[0071] In this embodiment, the rotating seat 110 is used as the main bearing component of the sliding mechanism 100, and the L-shaped frame 120 at the four ends and the guide sleeves 130 on both sides provide a mounting base for other components. The buckle 121 on the L-shaped frame 120 cooperates with the rubber block 122. By twisting the buckle 121, the rubber block 122 can be tightly attached to the outer wall of the busbar, thereby achieving reliable positioning of the rotating seat 110 and ensuring stable installation of the device on the busbar. The square frame 210 in the quick-plug mechanism 200 slides with the guide sleeve 130. The plug-in connection of the oblique block 214 and the square groove 131 realizes the rapid installation and disassembly of the expansion mechanism 300 on the sliding mechanism 100, and can be operated by one person. Compared with the installation method of the traditional wire-laying trolley, the work efficiency is greatly improved. The handle 1 220 is convenient for the staff to operate by hand. The square groove 222, the slider 223 and the square rod 221 connecting them cooperate with each other. By pressing the slider 223, the oblique block 214 and the square groove 131 can be easily separated, which further improves the convenience of disassembly.

[0072] like Figure 3 、 Figure 5 and Figure 6As shown, in this embodiment, the expansion mechanism 300 includes: a square plate 310, which is fixedly connected to the square frame 210, and a round rod 311 is rotatably connected at both ends between the two square plates 310, and the outer walls of both sides of the round rod 311 are provided with a threaded groove 312, and both ends of the round rod 311 are fixedly connected with a hexagonal block 313, a square plate 2 322, which is screwed on the threaded groove 312, can make the jaws expand and contract, and a ball 323 is provided in two groups, which are respectively provided on the outer wall of one side of the square plate 2 322 at one end and on the outer wall of the adjacent side, which can reduce the contact area with the bus jaws, reduce friction, and facilitate personnel to push, and a round rod 2 320 is provided with two groups, respectively fixed At both ends between the two square plates 310, a round roller 321 is rotatably connected to the center of the round rod 2 320, which can squeeze the insulating layer at the jaws, and then cooperate with the square plate 2 322 to clamp the jaws so that the bus jaws are engaged with the insulating layer. The partition 330 is fixed on the square plate 1 310 and can play a positioning and limiting role during installation. The multi-stage rod 340 is provided with a group, which is fixed on the square plate 1 310. A square rod 3 342 is fixedly connected between one end of a group of multi-stage rods 340 that can be extended, which can drive the auxiliary mechanism 400 to extend. The bolt 341 is screwed on the square plate 1 310 and is used to squeeze the outer wall of the multi-stage rod 340 and limit the extendable part of the multi-stage rod 340.

[0073] During specific implementation, the hexagonal block 313 is twisted to drive the round rod 1 311 to rotate, so as to realize the sliding of the square plate 2 322, and then the expansion and contraction of the bus jaws are accurately controlled. The operation is simple and flexible. Two sets of balls 323 are set on the outer wall of the square plate 2 322, which effectively reduces the contact area with the bus jaws and reduces the friction during pushing, making it easier for the staff to push the device. Through the round rod 2 320 and the round roller 1 321, when the jaws are clamped, the round roller 1 321 squeezes the insulating layer at the jaws and cooperates with the square plate 2 322 to ensure that the bus jaws are tightly clamped with the insulating layer, thereby improving the electrical connection stability and safety of the contact network. It is fixed on the square plate 1 310 through the partition 330, which plays a role in precise positioning and limiting when installing the device, ensuring that the expansion mechanism 300 is accurately installed on the bus, thereby improving the accuracy and efficiency of installation.

[0074] Example 2

[0075] like Figure 7-9As shown, in this embodiment, the auxiliary mechanism 400 includes: a slide rail 410, which is fixedly connected to two square rods 342, a square block 411 is slidably inserted into the slide rail 410, a round roller 2 412, which rotates on the outer wall of the square block 411, a square groove 3 413, which is opened in the inside of the square block 411, a handle 2 414, which is fixed to the bottom of the square block 411, a round hole is opened in the handle 2 414, and is communicated with the inside of the square groove 3 413, a round rod 3 420 is slidably inserted in the round hole, a square plate 3 421 is fixed to one end of the round rod 3 420, and is slidably inserted into the inside of the square groove 3 413, which can pick out the contact line in the bus and clear out the garbage in the bus during the movement of the auxiliary mechanism 400, a square plate 422 is fixed to the other end of the round rod 3 420, and a T-shaped frame 440 is fixed to At the center of the slide rail 410, square grooves 445 are provided on both sides of one end of the T-shaped frame 440. The square grooves 445 are slidably plugged into the square plate 422. Two latches 444 are provided, which are fixed on both sides of the T-shaped frame 440 and located above the square grooves 445. A group of guide sleeves 130 are provided and are opened on the outer wall of one side of the slide rail 410. A U-shaped frame 431 is inserted between the two square holes 430. The outer wall of the U-shaped frame 431 is screwed with a button 2 432. One end of the button 2 432 is rotatably connected to the slide rail 410. The spring 2 450 is fixed between the outer wall of the block 411 and the inner wall of the slide rail 410. The slide groove 441 is provided on the outer wall of the T-shaped frame 440. The L-shaped frame 2 442 is slidably plugged into the inside of the slide groove 441. The round roller 3 443 rotates at one end of the L-shaped frame 2 442.

[0076] During specific implementation, the rough surface at one end of the block 411 cooperates with the handle 2 414 to firmly clamp the insulating layer and separate it from the jaws. The operation is simple and efficient. The square plate 3 421 can not only pick out the contact wire in the bus, but also clean the impurities in the bus during the reciprocating movement of the auxiliary mechanism 400. The de-line and cleaning functions are realized in one action, which greatly improves the de-line efficiency. When sending the contact wire back to the bus, the round roller 3 443 moves close to the outer wall of the insulating layer, preventing the insulating layer from being located outside when the expansion mechanism 300 clamps and pushes, ensuring that the insulating layer is fully engaged with the jaws, and improving the safety and stability of the contact network.
