Description

Technical Field

[0001] This utility model relates to the field of cable transport technology, and more specifically to a cable transport device. Background Technology

[0002] Cable transport equipment is essentially a type of specialized equipment used for transporting, laying, storing, and protecting cables. Its core function is to solve the problems of cable movement and management during production, construction, and use, and to avoid the problems of low efficiency and easy damage to cables caused by manual operation.

[0003] A search revealed Chinese patent CN216638443U, which discloses a cable transport vehicle, comprising a vehicle body, a frame, and a bearing shaft for inserting cable reels. The top view of the vehicle body is C-shaped, and the frame is symmetrically fixed on both sides of the vehicle body. The frame includes a lifting screw, a support rod, a cable feeding seat fixed to the upper end of the lifting screw, and a drive mechanism.

[0004] However, the following defects still exist. When facing construction sites such as tunnels and basements, due to uneven ground or other unforeseen factors, the cable transport vehicle is prone to shaking during movement, which may cause the bearing shaft to detach from the cable laying seat, thereby causing damage to the cable laying reel and the cable. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cable transport device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a cable transport device, including a trolley, a cable reel, and a bearing shaft for threading the cable reel. The top of the trolley is fixedly connected to a base, and a hydraulic cylinder is provided inside the base. The top of the piston rod of the hydraulic cylinder is provided with a cable feeding mechanism for supporting the bearing shaft.

[0007] The top of the trolley is fixedly connected to a connecting frame. The upper surface of the connecting frame has two insertion holes. The top of the connecting frame is provided with a plug that mates with the two insertion holes. The plug has a V-shaped groove and two through slots. A fixing plate is fixedly connected to one side of the connecting frame. A connecting plate is provided on one side of the plug. Two protrusions that mate with the through slots are welded to one side of the connecting plate. A threaded rod that mates with the fixing plate is provided on one side of the connecting plate.

[0008] Furthermore, both of the two protrusions have multiple grooves evenly distributed on both sides.

[0009] Furthermore, the width of the protrusion is equal to the width of the through groove, and the end of the protrusion away from the connecting plate is in contact with the fixing plate.

[0010] Furthermore, one end of the threaded rod passes through the connecting plate and is threadedly connected to the fixing plate via a threaded sleeve.

[0011] Furthermore, the two opposite inclined surfaces of the V-groove are both in contact with the outer circumference of the bearing shaft, and a gap is left between the bottom of the V-groove and the bearing shaft.

[0012] Furthermore, the wire feeding mechanism includes a wire feeding seat fixedly connected to the top of the piston rod of the hydraulic cylinder. Two wire feeding rollers are arranged parallel to each other and spaced apart inside the wire feeding seat. The axes of the two wire feeding rollers are on the same horizontal plane. The bearing shaft is mounted between the two wire feeding rollers and contacts the outer walls of the two wire feeding rollers.

[0013] Furthermore, the outer walls of both pay-off rollers are fitted with a wear-resistant rubber layer, and both ends of the pay-off rollers are rotatably connected to the inner wall of the pay-off seat through bearings. The length of the pay-off rollers is greater than the diameter of the bearing shaft.

[0014] Furthermore, the outer circumferential walls at both ends of the bearing shaft are provided with multiple equally spaced slots along the axial direction, and both ends of the bearing shaft are fitted with locking rings that cooperate with the slots. The locking rings are fixed to the bearing shaft by positioning pins that pass through the slots.

[0015] Furthermore, the top of the trolley is equipped with a cable conveyor for laying cables.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model, by providing an insert block and a connecting plate, achieves stable transport of the bearing shaft and the pay-off reel, and avoids the bearing shaft from loosening from the pay-off assembly during transport, which would cause the pay-off reel to detach.

[0018] 2. By providing protrusions and grooves, this utility model achieves guidance and secondary fixation of the insertion block, further improving the overall stability of the device and preventing the insertion block from shifting due to uneven ground or external impact.

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Reference Figures 1-6This utility model provides a cable transport device, including a trolley 1, a cable reel 3, and a bearing shaft 4 for inserting into the cable reel 3. A base 6 is bolted to the top of the trolley 1, and a hydraulic cylinder 8 is installed inside the base 6. A connecting frame 5 is bolted to the top of the trolley 1. Two insertion holes 16 are formed on the upper surface of the connecting frame 5. A plug 11, which mates with the two insertion holes 16, is provided on the top of the connecting frame 5. Two through slots 12 are formed inside the plug 11. A fixing plate is bolted to one side of the connecting frame 5. 14. A connecting plate 13 is provided on one side of the insert block 11. Two protrusions 18 that mate with the through groove 12 are welded to one side of the connecting plate 13. The width of the protrusions 18 is equal to the width of the through groove 12. Multiple grooves 19 are evenly distributed on both sides of the two protrusions 18. The protrusions 18 are embedded in the through groove 12, and multiple contact points are formed between the protrusions 18 and the inner wall of the through groove 12 through the adjacent grooves 19, which increases the contact area and friction. At the same time, the through groove 12 provides a stable positioning and guiding function, which can further ensure the protrusions 18 are properly positioned. The stability of block 18 within the through groove 12 prevents relative sliding between the protrusion 18 and the through groove 12 due to bumps or vibrations during transportation, thus achieving secondary fixation of the insert block 11. The end of the protrusion 18 furthest from the connecting plate 13 contacts the fixing plate 14. One side of the connecting plate 13 is provided with a threaded rod 17 that mates with the fixing plate 14. One end of the threaded rod 17 passes through the connecting plate 13 and is threadedly connected to the fixing plate 14 via a threaded sleeve. The insert block 11 is inserted into the through groove 12, and the side of the connecting plate 13... Two protrusions 18 are inserted into the through slot 12, so that one end of the protrusion 18 contacts the fixing plate 14. Then, the threaded rod 17 is screwed into the threaded sleeve in the fixing plate 14. At this time, the connecting plate 13 contacts one side of the two extension ends of the insert block 11. As the threaded rod 17 is fixed to the fixing plate 14, the connecting plate 13 will press and fix the insert block 11, making the placement of the cable reel 3 on the bearing shaft 4 more stable, effectively preventing the cable reel 3 from shaking or shifting during cable transportation.

[0029] It should be noted that hydraulic cylinder 8 (specifically model MOB32X50) is a self-locking hydraulic cylinder, consisting of a cylinder barrel, cylinder head, and piston rod. The rodless chambers of two hydraulic cylinders 8 are directly connected in parallel via oil pipes to the same set of hydraulic valves, allowing pressurized oil to enter both cylinders simultaneously. This enables synchronous piston movement, allowing both hydraulic cylinders 8 to rise and fall simultaneously. The inner wall of the threaded cylinder has an axially arranged annular groove, into which a nylon 66 damping ring with a Shore hardness of 85A is embedded. The continuous axial clamping force generated by its elastic deformation forms a 15°-20° helical angle interference fit with the surface of the threaded rod 17. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, increasing the coefficient of friction between the threaded contact surfaces from 0.15 to 0.68 (according to ASTM). (D1894 standard test), effectively suppressing the loosening displacement caused by the springback of the threaded rod 17. The trolley 1 includes a frame, a support plate, a wheel assembly, and a pusher. All of the above are existing technologies, and those skilled in the art can set them according to actual needs, which will not be elaborated here.

[0030] The insert 11 has a V-groove 15. The two opposite inclined surfaces of the V-groove 15 are in contact with the outer circumference of the bearing shaft 4. There is a gap between the bottom of the V-groove 15 and the bearing shaft 4. The design of the V-groove 15 allows the bearing shaft 4 to be automatically aligned when placed, reducing the additional stress caused by placement deviation. At the same time, the gap between the bottom of the groove and the bearing shaft 4 provides space for the slight deformation of the bearing shaft 4, avoiding the bearing shaft 4 from being unable to rotate due to excessive compression. The V-groove 15 can also accommodate the placement of bearing shafts 4 of different thicknesses (the maximum diameter of the bearing shaft 4 does not exceed the width of the opening of the V-groove 15, and the V-groove 15 can be set according to actual needs).

[0031] In this embodiment (e.g.) Figure 3As shown), the top of the piston rod of the hydraulic cylinder 8 is provided with a wire feeding mechanism 10 for supporting the bearing shaft 4. The wire feeding mechanism 10 includes a wire feeding seat 101 fixed to the top of the piston rod of the hydraulic cylinder 8 by bolts. Two wire feeding rollers 102 are arranged parallel to each other and spaced apart inside the wire feeding seat 101. The axes of the two wire feeding rollers 102 are on the same horizontal plane. The bearing shaft 4 is mounted between the two wire feeding rollers 102 and contacts the outer wall of the two wire feeding rollers 102. By simultaneously activating the two hydraulic cylinders 8, the two hydraulic cylinders 8 drive their respective connected wire feeding mechanisms 10 to rise and fall synchronously, thereby realizing the height adjustment of the wire feeding reel 3 placed on the bearing shaft 4, which facilitates the adjustment of the wire feeding reel 3 to the required operating position. The outer wall of the pay-off roller 102 is covered with a wear-resistant rubber layer, and both ends of the pay-off roller 102 are rotatably connected to the inner wall of the pay-off seat 101 through bearings. The length of the pay-off roller 102 is greater than the diameter of the bearing shaft 4, which can ensure that the bearing shaft 4 is in close contact with the pay-off roller 102 during pay-off, increasing the friction between the pay-off roller 102 and the bearing shaft 4 and preventing the bearing shaft 4 from sliding during transport. At the same time, the driving force released by the cable is greater than the rolling friction between the wear-resistant rubber layer and the bearing shaft. The friction coefficient of the wear-resistant rubber layer does not affect the rotation of the bearing shaft 4. In addition, the elastic deformation of the wear-resistant rubber layer absorbs some vibration energy, further improving the stability of the bearing shaft 4 during transport.

[0032] However, the pay-off reel 3 can move laterally during transport. To avoid this situation, this embodiment (e.g.) Figure 3 As shown, multiple equally spaced slots 9 are provided on the outer circumference of both ends of the bearing shaft 4. Locking rings 7 that mate with the slots 9 are fitted on both ends of the bearing shaft 4. The locking rings 7 are fixed to the bearing shaft 4 by positioning pins that pass through the slots 9. The positioning pins can adjust the axial position of the locking rings 7 according to the different widths of the pay-off reels 3 until the locking rings 7 are in contact with the insert block 11. Then, the positioning pins are used to lock the locking rings 7 to the bearing shaft 4. The axial positioning of the pay-off reel 3 is achieved by the locking rings 7 at both ends of the bearing shaft 4 through the cooperation of the positioning pins and the slots 9, which effectively prevents the axial movement of the pay-off reel 3 during transportation and ensures the safety and reliability of cable transportation.

[0033] In this embodiment (e.g.) Figure 1As shown), the top of the trolley 1 is equipped with a cable conveyor 2 for laying cables. The height of the front and rear support rollers is adjusted according to the cable specifications to stabilize the cable. Then, the tension screw is turned counterclockwise by hand to loosen the rubber track. After the cable is placed between the tracks, the tension screw is turned clockwise to clamp it. The motor is then started to carry out the conveying operation. The cable conveyor 2 (specifically model DSJ-180 900) is existing technology. The cable conveyor 2 consists of a power drive unit, friction conveying rollers, frame body, guide and limit device and control system. It can provide stable traction for laying long-distance, large-section cables and achieve efficient, safe and damage-free conveying. Those skilled in the art can set it according to actual needs, which will not be described in detail here.

[0034] The transportation of cable reel 3 can be divided into the following steps:

[0035] S1: First, push the trolley 1 to the bottom of the frame where the wire feeding reel 3 is placed. Then, by activating the two hydraulic cylinders 8, the bearing shaft 4 is stably placed in the wire feeding mechanism 10. Afterward, the two hydraulic cylinders 8 are used again to lower the wire feeding reel 3 to a suitable height.

[0036] S2: Then, insert the insert 11 into the through groove 12, so that the two inclined surfaces of the V-groove 15 fit tightly with the bearing shaft 4. Next, insert the two protrusions 18 into the through groove 12, and then screw the threaded rod 17 into the threaded sleeve in the fixing plate 14 to fix the connecting plate 13 and the insert 11.

[0037] S3: Next, adjust the position of the locking ring 7 so that one side of the locking ring 7 contacts the insert block 11. After adjustment, use the positioning pin to fix the locking ring 7 to the bearing shaft 4;

[0038] S4: Finally, pull the trolley 1 to transport the wire reel 3 to the designated frame position, and then use the braking device to keep the trolley 1 in a stable and stationary state.

[0039] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship.
