Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of mating devices, specifically relating to a mating device for track plates of a tunneling machine. Background Technology
[0002] Tracks are a type of transmission device used in heavy machinery. Their main function is to increase the contact area and reduce the pressure on the ground, allowing the vehicle to work smoothly on soft ground. For example, mining tunneling machines need to use tracked chassis to move underground. During the long-term operation of the tunneling machine, due to vibration and tension, the pins connecting the two track plates may break or detach, causing the track to break off and preventing the tunneling machine from moving forward.
[0003] When repairing this type of fault, it is necessary to align the pin insertions of the two track plates located on both sides of the breakage position, also known as alignment. In the existing technology, workers need to use tools such as pry bars and wrenches to align the track plates, which is both laborious and inconvenient. Therefore, we propose a track plate alignment device for tunneling machines. Utility Model Content
[0004] To address the above problems, the purpose of this utility model is to provide a track plate matching device for a tunneling machine, which is applicable to tracks of different widths and greatly facilitates the matching of track blocks.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a track plate alignment device for a tunneling machine, comprising a spacing adjustment mechanism. The spacing adjustment mechanism includes a first telescopic rod sleeve, into which a first telescopic rod is inserted and installed. A first transmission screw is rotatably installed inside the first telescopic rod sleeve, and the first transmission screw is threadedly connected to the first telescopic rod. A fixing sleeve is provided at the bottom of one end of the first telescopic rod sleeve and at the bottom of one end of the first telescopic rod. A track width adaptation adjustment mechanism is fixedly installed inside the fixing sleeve. The track width adaptation adjustment mechanism includes a second telescopic rod sleeve fixedly installed inside the fixing sleeve. A third telescopic rod and a fourth telescopic rod are inserted and installed inside the second telescopic rod sleeve. A rotating shaft is rotatably installed through the top of the second telescopic rod sleeve, and a first bevel gear is installed at the bottom of the rotating shaft. A bidirectional transmission screw is rotatably installed inside the second telescopic rod sleeve, and a second bevel gear is sleeved on the outside of the bidirectional transmission screw. The bidirectional transmission screw is threadedly connected to the third and fourth telescopic rods. A track clamping and positioning mechanism is fixedly installed at one end of the third telescopic rod and one end of the fourth telescopic rod.
[0006] The beneficial effects of this utility model are as follows: When using this device, the upper and lower track clamps located at the end of the third telescopic rod, and the upper and lower track clamps located at the end of the fourth telescopic rod, are aligned with both sides of the track. The positioning protrusion at the bottom of the upper track clamp is aligned with and inserted into the groove formed at the connection point of two consecutive track plates near the track break-off position. Then, according to the track thickness, the crank handle at the top of the third transmission screw is rotated. Through the transmission between the third transmission screw and the fifth telescopic rod, the fifth telescopic rod, along with the lower track clamp, is raised, causing the positioning protrusion at the top of the lower track clamp to also embed into the groove. During this process, the extension lengths of the third and fourth telescopic rods can be adjusted according to the width of the track, thereby adjusting the spacing between the clamping blocks on both sides of the track. This allows the third telescopic rod sleeve to contact the side of the track. Through the cooperation of the upper and lower clamping blocks and the third telescopic rod sleeve, the two sets of track width adaptation adjustment mechanisms are fixed on the tracks located on both sides of the break-off position. When making this adjustment, the crank handle at the top of the shaft is rotated. The rotation of the shaft drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate the bidirectional transmission screw. This, in turn, drives the bidirectional transmission screw to rotate. The transmission between the third and fourth telescopic rods drives them to move in opposite directions or away from each other, changing the spacing between the track clamps. This fixes the two sets of track width adjustment mechanisms to the tracks on both sides of the break-off position. Then, the spacing between the two sets of track width adjustment mechanisms can be adjusted to bring them closer together, thereby pulling the track blocks on both sides of the break-off position closer together. This facilitates the alignment of the pins on the two track blocks and the insertion of the pins. During this adjustment, turning the handle at one end of the first transmission screw drives the first transmission screw to rotate. The transmission between the first telescopic rod and the first telescopic rod causes the first telescopic rod to extend and retract inside the first telescopic rod sleeve, thereby changing the total length of the first telescopic rod sleeve and the first telescopic rod. This, in turn, changes the distance between the two sets of track width adaptation adjustment mechanisms, bringing the two sets of track width adaptation adjustment mechanisms closer together. This helps to tighten the track and brings the track blocks on both sides of the break-off point closer together. At the same time, since both sets of track width adaptation adjustment mechanisms are located inside the fixed sleeve and on the same straight line, and the height of the clamping blocks on the track is the same, the tracks on both sides of the break-off point can be kept aligned, greatly facilitating the alignment of the track blocks.
[0007] To secure this device to the tracks:
[0008] As a further improvement to the above technical solution: the track clamping and positioning mechanism includes a track clamping block installed at one end of the third telescopic rod and one end of the fourth telescopic rod. A third telescopic rod sleeve is installed on the side of the track clamping block. A fifth telescopic rod is inserted and installed inside the third telescopic rod sleeve. A third transmission screw is rotatably installed on the inner side of the third telescopic rod sleeve. The third transmission screw is threadedly connected to the fifth telescopic rod. The bottom side of the fifth telescopic rod is fixed to the track clamping block.
[0009] The beneficial effects of this improvement are as follows: When using this device, the upper and lower track clamps at the end of the third telescopic rod, and the upper and lower track clamps at the end of the fourth telescopic rod, are aligned with the two sides of the track, respectively. The positioning protrusion at the bottom of the upper track clamp is aligned with and inserted into the groove formed by the connection of two consecutive track plates near the track break-off position. Then, according to the thickness of the track, the crank at the top of the third transmission screw is rotated. Through the transmission between the third transmission screw and the fifth telescopic rod, the fifth telescopic rod, along with the lower track clamp, is driven to rise, so that the positioning protrusion at the top of the lower track clamp is also embedded in the groove. During this process, the extension length of the third and fourth telescopic rods can be adjusted according to the width of the track, thereby adjusting the distance between the upper track clamps on both sides. This allows the sleeve of the third telescopic rod to contact the side of the track. Through the cooperation of the upper track clamp, the lower track clamp, and the sleeve of the third telescopic rod, the two sets of track width adaptation adjustment mechanisms are fixed on the tracks on both sides of the break-off position.
[0010] To secure the tracks:
[0011] As a further improvement to the above technical solution: the bottom of the upper track clamping block and the top of the lower track clamping block are both provided with integrally formed positioning protrusions.
[0012] The beneficial effects of this improvement are: the positioning protrusion is used to cooperate with the groove on the track, and the track is fixed as the upper track clamping block descends and the lower track clamping block rises.
[0013] In order to rotate the first transmission screw, the rotating shaft, and the third transmission screw:
[0014] As a further improvement to the above technical solution: a crank handle is installed at one end of the first transmission screw, the rotating shaft, and the third transmission screw.
[0015] The beneficial effect of this improvement is that the crank is used to manually rotate the first transmission screw, the rotating shaft, and the third transmission screw.
[0016] To power the lights:
[0017] As a further improvement to the above technical solution: a battery compartment is installed on the top of the first telescopic rod sleeve, and a battery is installed inside the battery compartment.
[0018] The beneficial effect of this improvement is that the battery is used to power the lighting.
[0019] To improve the ease of maintenance:
[0020] As a further improvement to the above technical solution: lighting lamps are fixedly provided at the bottom of the first telescopic rod sleeve and on the side of the second telescopic rod sleeve, and a lighting switch is installed on the top of the battery compartment.
[0021] The beneficial effects of this improvement are as follows: the lighting switch is used to control the switching of the lights. When the lighting conditions are poor, the lights can be turned on by the lighting switch. The lights set at the bottom of the first telescopic rod sleeve and the lights on the side of the second telescopic rod sleeve can provide good lighting for the track maintenance area, improving the convenience of maintenance.
[0022] To facilitate the movement of this device:
[0023] As a further improvement to the above technical solution: a handle is installed on the top of the first telescopic rod sleeve.
[0024] The beneficial effect of this improvement is that the handle facilitates the movement of this device.

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0033] like Figure 1-5 As shown, a track shoe mating device for a tunneling machine includes a spacing adjustment mechanism 1. The spacing adjustment mechanism 1 includes a first telescopic rod sleeve 2, a first telescopic rod 3 inserted and installed inside the first telescopic rod sleeve 2, and a first transmission screw 4 rotatably installed inside the first telescopic rod sleeve 2. The first transmission screw 4 is threadedly connected to the first telescopic rod 3. A fixing sleeve 5 is provided at one bottom end of the first telescopic rod sleeve 2 and at one bottom end of the first telescopic rod 3. A track width adaptation adjustment mechanism 6 is fixedly installed inside the fixing sleeve 5. The track width adaptation adjustment mechanism 6 includes a track shoe fixedly installed inside the fixing sleeve 5. The second telescopic rod sleeve 7 is located on the side. A third telescopic rod 8 and a fourth telescopic rod 9 are inserted and installed inside the second telescopic rod sleeve 7. A rotating shaft 10 is installed through and rotatably on the top of the second telescopic rod sleeve 7. A first bevel gear 11 is installed at the bottom of the rotating shaft 10. A bidirectional transmission screw 12 is rotatably installed on the inner side of the second telescopic rod sleeve 7. A second bevel gear 13 is sleeved on the outer side of the bidirectional transmission screw 12. The bidirectional transmission screw 12 is threadedly connected to the third telescopic rod 8 and the fourth telescopic rod 9. A track clamping and positioning mechanism is fixedly installed at one end of the third telescopic rod 8 and one end of the fourth telescopic rod 9.
[0034] In use, the track upper clamp 14 and track lower clamp 15 located at the end of the third telescopic rod 8, and the track upper clamp 14 and track lower clamp 15 located at the end of the fourth telescopic rod 9, are aligned with both sides of the track. The positioning protrusion 16 at the bottom of the track upper clamp 14 is aligned with and inserted into the groove 27 formed at the connection point of two consecutive track plates 26 near the track break-off position. Then, depending on the track thickness, the crank 20 at the top of the third transmission screw 19 is rotated. Through the transmission between the third transmission screw 19 and the fifth telescopic rod 18, the fifth telescopic rod 18, along with the track lower clamp 15, is raised, causing the positioning protrusion 16 at the top of the track lower clamp 15 to also engage. Within the groove 27, during this process, the extension lengths of the third telescopic rod 8 and the fourth telescopic rod 9 can be adjusted according to the width of the track, thereby adjusting the spacing between the track clamping blocks 14 on both sides, so that the third telescopic rod sleeve 17 can contact the side of the track. Through the cooperation of the track clamping blocks 14, the track lower clamping blocks 15, and the third telescopic rod sleeve 17, the two sets of track width adaptation adjustment mechanisms 6 are respectively fixed on the tracks located on both sides of the break-off position. When performing this adjustment, the crank handle 20 at the top of the rotating shaft 10 is rotated, and the rotation of the rotating shaft 10 drives the first bevel gear 11 to rotate, thereby driving the second bevel gear 13 to drive the bidirectional transmission screw 12 to rotate. Then, through the transmission between the bidirectional transmission screw 12 and the third telescopic rod 8 and the fourth telescopic rod 9, the third telescopic rod 8 and the fourth telescopic rod 9 are driven to move in opposite directions or in opposite directions, thereby changing the spacing between the clamping blocks 14 on the track, completing the fixation of the two sets of track width adaptation adjustment mechanisms 6 with the tracks on both sides of the break-off position. Subsequently, the spacing between the two sets of track width adaptation adjustment mechanisms 6 can be adjusted so that they move closer to each other, thereby pulling the track blocks on both sides of the break-off position closer together, facilitating the alignment of the pin holes on the two track blocks and the insertion of the pins. When performing this adjustment, turning the crank 20 at one end of the first transmission screw 4 will drive the first transmission screw 4 to rotate. The transmission between the first transmission screw 4 and the first telescopic rod 3 drives the first telescopic rod 3 to extend and retract inside the first telescopic rod sleeve 2, thereby changing the total length of the first telescopic rod sleeve 2 and the first telescopic rod 3. This, in turn, changes the distance between the two sets of track width adaptation adjustment mechanisms 6, bringing the two sets of track width adaptation adjustment mechanisms 6 closer together. This helps to tighten the track and brings the track blocks on both sides of the break-off point closer together. At the same time, since the two sets of track width adaptation adjustment mechanisms 6 are both located inside the fixed sleeve 5 and on the same straight line, and the height of the track clamping blocks 14 is the same, the tracks on both sides of the break-off point can be kept aligned, greatly facilitating the alignment of the track blocks.
[0035] The track clamping and positioning mechanism includes a track clamping block 14 installed at one end of the third telescopic rod 8 and one end of the fourth telescopic rod 9. A third telescopic rod sleeve 17 is installed on the side of the track clamping block 14. A fifth telescopic rod 18 is inserted and installed inside the third telescopic rod sleeve 17. A third transmission screw 19 is rotatably installed on the inner side of the third telescopic rod sleeve 17. The third transmission screw 19 is threadedly connected to the fifth telescopic rod 18. The bottom side of the fifth telescopic rod 18 is fixed to the track lower clamping block 15.
[0036] When using this device, align the upper track clamp 14 and lower track clamp 15 at the end of the third telescopic rod 8 and the upper track clamp 14 and lower track clamp 15 at the end of the fourth telescopic rod 9 with the two sides of the track, respectively. Align the positioning protrusion 16 at the bottom of the upper track clamp 14 with the groove 27 formed at the connection point of two consecutive track plates 26 near the track break-off position and insert it. Then, depending on the thickness of the track, rotate the crank 20 at the top of the third transmission screw 19. The fifth telescopic rod 18 is driven through the transmission between the third transmission screw 19 and the fifth telescopic rod 18. As the track lower clamp 15 rises, the positioning protrusion 16 on the top of the track lower clamp 15 is also embedded in the groove 27. During this process, the extension length of the third telescopic rod 8 and the fourth telescopic rod 9 can be adjusted according to the width of the track, thereby adjusting the distance between the track upper clamps 14 on both sides, so that the third telescopic rod sleeve 17 can contact the side of the track. Through the cooperation of the track upper clamp 14, the track lower clamp 15, and the third telescopic rod sleeve 17, the two sets of track width adaptation adjustment mechanisms 6 are respectively fixed on the tracks located on both sides of the break-off position.
[0037] The bottom of the upper track clamping block 14 and the top of the lower track clamping block 15 are both provided with integrally formed positioning protrusions 16.
[0038] The positioning protrusion 16 is used to engage with the groove on the track, and the track is fixed as the upper track clamping block 14 descends and the lower track clamping block 15 rises.
[0039] A crank handle 20 is installed at one end of the first transmission screw 4, the rotating shaft 10, and the third transmission screw 19.
[0040] The crank handle 20 is used to manually rotate the first transmission screw 4, the rotating shaft 10, and the third transmission screw 19.
[0041] A battery compartment 21 is installed on the top of the first telescopic rod sleeve 2, and a battery 25 is installed inside the battery compartment 21.
[0042] Battery 25 is used to power the lighting lamp 22.
[0043] Lighting lamps 22 are fixedly installed at the bottom of the first telescopic rod sleeve 2 and on the side of the second telescopic rod sleeve 7, and a lighting switch 23 is installed on the top of the battery compartment 21.
[0044] The lighting switch 23 is used to control the switching of the lighting lamp 22. When the lighting conditions are poor, the lighting lamp 22 can be turned on by the lighting switch 23. The lighting lamp 22 set at the bottom of the first telescopic rod sleeve 2 and the lighting lamp 22 on the side of the second telescopic rod sleeve 7 can provide good lighting for the track maintenance area and improve the convenience of maintenance.
[0045] A handle 24 is installed on the top of the first telescopic rod sleeve 2.
[0046] The handle 24 is used to facilitate the movement of this device.
[0047] The working principle and usage process of this utility model are as follows: When using this device, the upper track clamp 14 and lower track clamp 15 located at the end of the third telescopic rod 8, and the upper track clamp 14 and lower track clamp 15 located at the end of the fourth telescopic rod 9, are aligned with both sides of the track. The positioning protrusion 16 at the bottom of the upper track clamp 14 is aligned with and inserted into the groove 27 formed at the connection point of two consecutive track plates 26 near the track break-off position. Then, according to the track thickness, the crank 20 at the top of the third transmission screw 19 is rotated. Through the transmission between the third transmission screw 19 and the fifth telescopic rod 18, the fifth telescopic rod 18, along with the lower track clamp 15, is driven to rise, causing the positioning protrusion 16 at the top of the lower track clamp 15 to also embed into the groove 27. During this process... The extension lengths of the third telescopic rod 8 and the fourth telescopic rod 9 can be adjusted according to the width of the track, thereby adjusting the spacing between the track clamps 14 on both sides. This allows the third telescopic rod sleeve 17 to contact the side of the track. Through the cooperation of the track clamps 14, the track lower clamps 15, and the third telescopic rod sleeve 17, the two sets of track width adaptation adjustment mechanisms 6 are fixed on the tracks on both sides of the disconnection position. When making this adjustment, the crank handle 20 at the top of the rotating shaft 10 is rotated. The rotation of the rotating shaft 10 drives the first bevel gear 11 to rotate, which in turn drives the second bevel gear 13 to drive the bidirectional transmission screw 12 to rotate. This, in turn, drives the third telescopic rod 8 and the fourth telescopic rod 9 through the transmission between the bidirectional transmission screw 12 and the third telescopic rod 8 and the fourth telescopic rod 9. The retractor 9 moves in opposite directions to change the spacing between the clamping blocks 14 on the track, thus fixing the two sets of track width adaptation adjustment mechanisms 6 to the tracks on both sides of the break-off position. Then, the spacing between the two sets of track width adaptation adjustment mechanisms 6 can be adjusted to bring them closer together, thereby pulling the track blocks on both sides of the break-off position closer together. This facilitates the alignment of the pins on the two track blocks and the insertion of the pins. During this adjustment, rotating the handle 20 at one end of the first transmission screw 4 drives the first transmission screw 4 to rotate. Through the transmission between the first transmission screw 4 and the first telescopic rod 3, the first telescopic rod 3 extends and retracts inside the first telescopic rod sleeve 2, thereby changing the total length of the first telescopic rod sleeve 2 and the first telescopic rod 3, and thus changing the spacing between the two sets of track width adaptation adjustment mechanisms 6. The spacing between the track width adjustment mechanisms 6 brings the two sets of track width adjustment mechanisms 6 closer together, which helps to tighten the track and bring the track blocks on both sides of the breakage point closer together. At the same time, since both sets of track width adjustment mechanisms 6 are located inside the fixed sleeve 5 and are on the same straight line, and the height of the track clamping blocks 14 is the same, the tracks on both sides of the breakage point can be kept aligned, which greatly facilitates the alignment of the track blocks. In addition, this device is also equipped with a lighting lamp 22. When the lighting conditions are poor, the lighting lamp 22 can be turned on by the lighting switch 23. The lighting lamp 22 set at the bottom of the first telescopic rod sleeve 2 and the lighting lamp 22 on the side of the second telescopic rod sleeve 7 can provide good lighting for the track maintenance area, improving the convenience of maintenance.
