[0011] The guiding mechanism includes a base frame, a movable seat, a turntable, a protective frame, a guide frame, and multiple nylon guide wheels.

Positioning bolts are slidably inserted into the four positioning holes.

[0014] A method for using a cable laying device for subway tunnels includes the following steps: S1. Cable Conveying: Cable rollers carrying cables are stacked on a rail traction vehicle. One of the rollers is vertically pushed between the limiting frame and the moving frame, allowing the two carrier wheels to insert into the cable roller. The moving motor, in conjunction with the moving worm and worm wheel, drives a bidirectional threaded rod to rotate. This causes the bidirectional threaded rod to move two moving blocks away from each other. Under the position constraint of the abutment block, the two moving blocks synchronously drive the two carrier wheels to gradually contact the top and bottom surfaces inside the cable roller. Then, the cylinder is activated, causing the carrier frame to move upwards. This, in turn, causes the carrier frame, along with the moving frame and the abutment block, to synchronously move the two carrier wheels upwards. The two carrier frames synchronously compress and move the supporting cable roller upwards, separating the bottom of the cable roller from the base plate. At this point, under the position constraint of the guide frame, the moving frame moves, allowing one end of the rotating wheel to insert into the cable roller. Internally, by rotating the adjusting worm gear, the adjusting worm gear, in conjunction with the adjusting worm wheel and the moving threaded rod, can move and adjust the height of the connecting block. This allows the connecting block to drive the rotating wheel to gradually press against the inner top surface of the cable roller, enabling the rotating wheel and the carrier wheel to smoothly support the cable roller. At this time, by controlling the start of the connecting motor, the connecting motor, in conjunction with the drive gear and the connecting gear, can drive the connecting rod to rotate. The rotating connecting rod can drive the connecting worm gear to rotate, which in turn can drive the rotating wheel to rotate. This rotating wheel can then press and drive the cable roller to rotate synchronously, enabling the rotating cable roller to efficiently transport the cable. At the same time, during the synchronous movement of the rail traction vehicle, the cable can be efficiently laid in the specified direction. The equipment can also easily adjust its own structure according to the specifications of the cable roller, thus easily suspending the cable roller. S2. Guided Laying: One end of the delivered cable is placed between the tops of multiple nylon guide wheels, allowing for smoother cable delivery. Simultaneously, the orientation of the guide frame is adjusted by rotating the turntable, and the guide worm gear, in conjunction with the guide worm wheel, drives the guide threaded rod to rotate. This rotating guide threaded rod allows for adjustment of the position of the movable seat, facilitating easy adjustment of the cable delivery direction. Rotating the adjusting limit threaded rod allows for synchronous movement of two guide rods, which, in conjunction with the side frame, synchronously drive the bottom tube to deflect at the appropriate angle. Adjusting the height of the positioning bolts allows for convenient adjustment of the support frame and support rods, enabling the guide frame support angle to be adjusted according to actual guiding requirements. This ensures the nylon guide wheels provide sufficient support for cable delivery, preventing accidental cable lifting during transport.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: (1) In this invention, during use, cable rollers carrying cables are stacked on a rail traction vehicle, and one of them is vertically pushed between the limiting frame and the moving frame. At this time, the two carrier wheels can be inserted into the inside of the cable roller. Then, by controlling the start of the moving motor, the moving motor, together with the moving worm and the moving worm wheel, can drive the bidirectional threaded rod to rotate. Then, the bidirectional threaded rod can move the two moving blocks away from each other, so that the two moving blocks, under the position restriction of the abutment block, can synchronously drive the two carrier wheels to gradually fit against the inner top surface and inner bottom surface of the cable roller. Then, by controlling the start of the cylinder, the cylinder can drive the carrier frame to move upward, so that the carrier frame, together with the moving frame and the abutment block, can synchronously drive the two carrier wheels to move upward, so that the two carrier frames can synchronously squeeze and drive the supporting cable roller to move upward synchronously, so that the bottom of the cable roller separates from the bottom plate. At this time, under the position restriction of the guide frame, the moving frame moves so that the moving frame can drive one end of the rotating wheel to insert into the inside of the cable roller. Then, by rotating the adjusting worm, the two carrier wheels can be inserted into the cable roller. The adjusting worm gear, in conjunction with the adjusting worm wheel and the moving threaded rod, can adjust the height of the connecting block. This allows the connecting block to drive the rotating wheel to gradually press against the inner top surface of the cable roller, enabling the rotating wheel and the carrier wheel to smoothly support the cable roller. At this point, by controlling the start of the connecting motor, the connecting motor, in conjunction with the drive gear and the connecting gear, can drive the connecting rod to rotate. The rotating connecting rod can then drive the connecting worm gear to rotate, which in turn drives the rotating wheel to rotate. This rotating wheel, in turn, can press and drive the cable roller to rotate synchronously, enabling the rotating cable roller to efficiently transport the cable. Simultaneously, during the synchronous movement of the rail traction vehicle, the cable can be efficiently laid in the specified direction. The equipment can also be easily adjusted according to the specifications of the cable roller, allowing for convenient suspension of the cable roller and convenient cable transport according to the actual laying situation, thus improving the versatility of the equipment in practical applications.

[0016] (2) In this invention, one end of the cable is placed between the tops of multiple nylon guide wheels, so that the cable can be transported and laid more smoothly. At the same time, the orientation of the guide frame is adjusted by rotating the turntable and the guide worm is rotated so that the guide worm can drive the guide thread rod to rotate in conjunction with the guide worm wheel. Then, the rotating guide thread rod can move and adjust the position of the moving seat, so that the cable transport direction can be easily adjusted. And by rotating and adjusting the limiting thread rod, the limiting thread rod can drive the two guide rods to move synchronously. Then, the guide rods and the side frame can drive the bottom tube to deflect at the use angle synchronously. At the same time, by adjusting the height of the positioning bolt, the use height of the support frame and the support rod can be easily adjusted. Then, the support angle of the guide frame can be adjusted according to the actual guiding needs, so that the nylon guide wheels can fully support and transport the cable, avoid the cable from floating up unexpectedly during the transport process, and improve the actual use effect of the equipment.

A movable worm gear 109 is rotatably connected to the top of the frame 103, and the movable worm gear 109 meshes with a movable worm wheel. A movable motor 110 is fixedly connected to the outer surface of one side of the frame 103, and the output end of the movable motor 110 is fixedly connected to one end of the movable worm gear 109.

At this time, the two carrier wheels 106 can be inserted into the cable rollers 4. Then, the moving motor 110 is started by control.The moving motor 110, in conjunction with the moving worm gear 109 and the moving worm wheel, drives the bidirectional threaded rod 107 to rotate. This causes the bidirectional threaded rod 107 to move two moving blocks 108 away from each other. Under the positional constraint of the abutment block 105, the two moving blocks 108 synchronously drive the two carrier wheels 106 to gradually contact the inner top and bottom surfaces of the cable roller 4. Then, by controlling the start cylinder 111, the cylinder 111 drives the carrier frame 103 upward. The carrier frame 103, in conjunction with the moving frame 113 and the abutment block 105, synchronously drives the two carrier wheels 106 upward.

The lever 115 can move to adjust the height of the connecting block 116, thereby allowing the connecting block 116 to drive the rotating wheel 117 to gradually press against the inner top surface of the cable roller 4. This allows the rotating wheel 117, in conjunction with the carrier wheel 106, to smoothly support the cable roller 4. At this time, by controlling the start of the connecting motor 122, the connecting motor 122, in conjunction with the drive gear 123 and the connecting gear 121, can drive the connecting rod 119 to rotate. The rotating connecting rod 119 can then drive the connecting worm gear 120 to rotate, which in turn, in conjunction with the connecting worm wheel, can drive the rotating wheel 117 to rotate. This, in turn, allows the rotating wheel 117 to press against and synchronously rotate the cable roller 4, enabling the cable roller 4 to efficiently transport the cable. Simultaneously, during the synchronous movement of the rail traction vehicle 3, the cable can be efficiently laid along the designated direction. Furthermore, the equipment can easily adjust its structure according to the specifications of the cable roller 4, allowing for convenient suspension of the cable roller 4. Please see Figure 11 and Figure 12The guide mechanism 2 provides a cable guiding base and is mounted on the rail traction vehicle 3. The guide mechanism 2 includes a base frame 201, a movable seat 204, a turntable 205, a protective frame 207, a guide frame 215, and multiple nylon guide wheels 217. The base frame 201 is fixedly connected to the top of the rail traction vehicle 3. The movable seat 204 is slidably disposed inside the base frame 201.

Guide threaded rods 202 are rotatably connected between the inner walls of the two sides of the bottom frame 201. The guide threaded rods 202 are threadedly connected to the movable seat 204. A guide worm gear is fitted onto the outer surface of the guide threaded rods 202. A guide worm 203 is rotatably connected inside the bottom frame 201, meshing with the guide worm gear. A bolt 206 is threadedly connected to the top of the turntable 205, with its bottom end fitting against the top of the movable seat 204.

A limit threaded rod is rotatably connected to the outer surface of one side of the protective frame 207. 208. Each bottom tube 210 has a side frame 212 fixedly connected to one side of its outer surface. The four side frames 212 are divided into two groups.

One end of the conveyed cable is placed between the tops of multiple nylon guide wheels 217, so that the cable can be conveyed and laid more smoothly. At the same time, the orientation of the guide frame 215 is adjusted by rotating the turntable 205, and the guide worm 203 is rotated to adjust the direction of the guide worm 203. The guide worm gear can drive the guide threaded rod 202 to rotate, which in turn allows the rotating guide threaded rod 202 to move and adjust the position of the movable seat 204, thereby facilitating the adjustment of the cable conveying direction. By rotating and adjusting the limiting threaded rod 208, the limiting threaded rod 208 can drive the two guide rods 209 to move synchronously. In turn, the guide rods 209, together with the side frame 212, can synchronously drive the bottom tube 210 to deflect at the operating angle. At the same time, by adjusting the height of the positioning bolt 211, the operating height of the support frame 213 and the support rod 214 can be easily adjusted. This allows the support angle of the guide frame 215 to be adjusted according to the actual guiding requirements, so that the nylon guide wheel 217 can fully support and convey the cable, preventing the cable from accidentally floating during the conveying process.

[0022] The following provides a detailed description of the method of using a subway tunnel cable laying device provided in an embodiment of the present invention, which includes the following steps: Step 1, Cable Conveying: Stack the cable rollers 4 carrying cables onto the rail traction vehicle 3, and simultaneously push one of them vertically between the limiting frame 102 and the moving frame 113. At this point, the two carrier wheels 106 can be inserted into the cable rollers 4. Then, the moving motor 110 is started by controlling it, so that the moving motor 110, together with the moving worm 109 and the moving worm wheel, can drive the bidirectional threaded rod 107 to rotate. This causes the bidirectional threaded rod 107 to move the two moving blocks 108 away from each other, so that the two moving blocks 108, under the position restriction of the abutment block 105, can synchronously drive the two cables. The carrier rollers 106 gradually come into contact with the inner top and bottom surfaces of the cable roller 4. Then, by controlling the start cylinder 111, the cylinder 111 drives the carrier frame 103 upwards. This causes the carrier frame 103, in conjunction with the moving frame 113 and the abutment block 105, to synchronously drive the two carrier rollers 106 upwards. This allows the two carrier frames 103 to synchronously press and drive the supporting cable roller 4 upwards, separating the bottom of the cable roller 4 from the base plate 101. At this point, under the positional constraint of the guide frame 112, the moving frame 113 moves, allowing it to drive one end of the rotating wheel 117 to insert into the cable roller 4, thereby... By rotating the adjusting worm gear 118, the adjusting worm gear 118, in conjunction with the adjusting worm wheel and the moving threaded rod 115, can move the adjusting linkage block 116 to adjust its height. This allows the linkage block 116 to drive the rotating wheel 117 to gradually press against the inner top surface of the cable roller 4, enabling the rotating wheel 117, in conjunction with the carrier wheel 106, to smoothly support the cable roller 4. At this time, by controlling the start of the linkage motor 122, the linkage motor 122, in conjunction with the drive gear 123 and the linkage gear 121, can drive the linkage rod 119 to rotate. The rotating linkage rod 119 then drives the linkage worm gear 120. The rotation of the worm gear 120, in conjunction with the worm wheel, drives the rotating wheel 117 to rotate. This rotating wheel 117 then compresses and drives the cable roller 4 to rotate synchronously, enabling the cable roller 4 to efficiently transport the cable. Simultaneously, during the synchronous movement of the track traction vehicle 3, the cable can be laid efficiently along the specified direction. Furthermore, the equipment can easily adjust its structure according to the specifications of the cable roller 4, thereby easily suspending the cable roller 4 and facilitating cable transport according to the actual laying conditions, thus improving the versatility of the equipment in practical applications. Step 2, Guided Laying: Place one end of the delivered cable between the tops of multiple nylon guide wheels 217 to ensure smoother cable delivery. Simultaneously, adjust the orientation of the guide frame 215 by rotating the turntable 205 and rotate the guide worm 203. The guide worm 203, in conjunction with the guide worm wheel, drives the guide threaded rod 202 to rotate. This allows the rotating guide threaded rod 202 to move and adjust the position of the movable seat 204, facilitating easy adjustment of the cable delivery direction. The limit threaded rod can also be adjusted by rotating it. 208 enables the limiting threaded rod 208 to drive the two guide rods 209 to move synchronously, thereby enabling the guide rods 209 to work in conjunction with the side frame 212 to synchronously drive the bottom tube 210 to deflect at the operating angle. At the same time, by adjusting the height of the positioning bolt 211, the operating height of the support frame 213 and the support rod 214 can be easily adjusted. Furthermore, the support angle of the guide frame 215 can be adjusted according to the actual guiding requirements, so that the nylon guide wheel 217 can fully support and transport the cable, preventing accidental lifting of the cable during the transport process and improving the actual use effect of the equipment.

10. A method of using a cable laying device for subway tunnels, characterized in that, The method applied to the subway tunnel cable laying device as described in claim 9 includes the following steps: S1. Cable transport: The cable rollers (4) carrying the cable are stacked on the rail traction vehicle (3), and one of them is pushed vertically between the limiting frame (102) and the moving frame (113). At this time, the two carrier wheels (106) can be inserted into the cable rollers (4). Then, the moving motor (110) is started by controlling the motor, so that the moving motor (110) can drive the bidirectional threaded rod (107) to rotate in conjunction with the moving worm (109) and the moving worm wheel. Then, the bidirectional threaded rod (107) can move the two moving blocks (108) away from each other, so that the two moving blocks (108) can be restricted by the position of the abutment block (105). The two carrier wheels (106) are driven to gradually fit against the top and bottom surfaces of the cable roller (4) in sync. Then, by controlling the starting cylinder (111), the cylinder (111) can drive the carrier frame (103) to move upward. Then, the carrier frame (103), together with the moving frame (113) and the abutment (105), drives the two carrier wheels (106) to move upward in sync. This allows the two carrier frames (103) to squeeze and drive the supporting cable roller (4) to move upward in sync, so that the bottom of the cable roller (4) separates from the base plate (101). At this time, the moving frame (113) is moved under the position restriction of the guide frame (112), so that the moving frame (113) can drive the cable roller (4) to move upward. One end of the rotating wheel (117) is inserted into the cable roller (4). Then, by rotating the adjusting worm (118), the adjusting worm (118) can move the adjusting linkage block (116) to adjust the height in conjunction with the adjusting worm wheel and the moving threaded rod (115). This allows the linkage block (116) to drive the rotating wheel (117) to gradually press against the top surface inside the cable roller (4), so that the rotating wheel (117) and the carrier wheel (106) can smoothly carry the cable roller (4). At this time, by controlling the start of the linkage motor (122), the linkage motor (122) can work with the drive gear (123) and the linkage gear (121) to... The connecting rod (119) is driven to rotate, so that the rotating connecting rod (119) can drive the connecting worm (120) to rotate, and then the rotating connecting worm (120) can drive the rotating wheel (117) to rotate, and then the rotating wheel (117) can squeeze and drive the cable roller (4) to rotate synchronously, so that the rotating cable roller (4) can efficiently transport the cable. At the same time, during the synchronous movement of the rail traction vehicle (3), the cable can be laid efficiently along the specified direction. Meanwhile, the equipment can conveniently adjust its own structure according to the specifications of the cable roller (4), and then conveniently suspend the cable roller (4). S2. Guided Laying: One end of the cable is placed between the tops of multiple nylon guide wheels (217) to allow for smoother cable laying. Simultaneously, the orientation of the guide frame (215) is adjusted by rotating the turntable (205), and the guide worm (203) is rotated to engage with the guide worm wheel, driving the guide thread rod (202) to rotate. This allows the rotating guide thread rod (202) to move and adjust the position of the movable seat (204), facilitating easy adjustment of the cable's conveying direction. The limit screw is also adjusted by rotating... The threaded rod (208) enables the limiting threaded rod (208) to drive the two guide rods (209) to move synchronously. Then, the guide rod (209) and the side frame (212) can synchronously drive the bottom tube (210) to deflect at the working angle. At the same time, by adjusting the height of the positioning bolt (211), the working height of the support frame (213) and the support rod (214) can be easily adjusted. In addition, the support angle of the guide frame (215) can be adjusted according to the actual guiding needs, so that the nylon guide wheel (217) can fully support and transport the cable, and avoid the cable from floating up unexpectedly during the transport process.
