Description

Technical Field

[0001] This utility model belongs to the technical field of cable construction, specifically a cable laying traction device. Background Technology

[0002] Cable laying traction devices are specialized mechanical equipment used for laying power and communication cables. They provide stable traction through an electric or hydraulic drive system, and, in conjunction with guide pulleys and a tension control system, enable the safe and efficient laying of cables in pipes, tunnels, or direct-buried trenches. These devices typically consist of a drive motor, traction wheels, an intelligent control box, and an overload protection system. They feature stepless speed regulation and emergency braking functions, significantly improving construction efficiency and reducing the safety risks of manual pulling. They are widely used in urban power grid upgrades, subway tunnel cable projects, and other similar applications.

[0003] Patent document CN114629050A describes a wire and cable traction device, including a motor, a rolling shaft at one end of the motor, a drive wheel at the end of the rolling shaft away from the motor, a base plate below the motor, and hinge holes at both ends of the base plate. A roller is located at one end of the first hinge hole, and a groove is located at the end of the roller away from the first hinge hole. A bolt is inserted through the interior of the first groove. A sliding rod is located on the upper surface of the base plate, with a positioning hole through one end of the sliding rod and a connecting rod at the other end. A second hinge hole is located at the end of the connecting rod away from the sliding rod.

[0004] Existing cable laying traction devices have certain shortcomings in use. The traction device mainly uses a motor to drive the traction wheel to move the cable. The traction device itself cannot be arbitrarily adjusted according to the cable size, making it unsuitable for cable structures of different diameters. Secondly, a single traction device can only drive one cable at a time. When the traction device is used for multiple cables, the feeding and discharging guidance of multiple cable structures needs to be solved, making it unable to flexibly apply to multiple cable structures.

[0005] In summary, existing traditional traction devices mainly use a motor to drive a traction wheel to move the cable. The traction device itself cannot be arbitrarily adjusted according to the cable size, which makes it unsuitable for cable structures of different diameters. Utility Model Content

[0006] This utility model provides a cable laying traction device, which can solve the problem in the prior art that the traction device itself cannot be arbitrarily adjusted according to the cable size, making the traction device unsuitable for cable structures of different diameters:

[0007] A cable laying traction device includes a movable base and a traction device. The traction device is fixedly installed on the upper surface of the movable base. Both ends of the movable base are provided with inclined surfaces, and both ends of the movable base are provided with guides above the inclined surfaces. The guides include a lower rotating rod and an upper rotating rod. The upper rotating rod is movably installed above the lower rotating rod. Several sets of lead screws are movably installed on the outer surfaces of the lower rotating rod and the upper rotating rod. A clamping device is fixedly installed at the upper end of the traction device, and a clamping plate is movably installed at the lower part of the clamping device. The clamping plate is movably installed at the upper inner side of the traction device.

[0008] As a further technical solution of this utility model, docking heads are movably installed at the middle of both ends of the lower rotating rod and the upper rotating rod, and a push block is provided at one end of the docking head. By pushing the push block, the user can drive the docking head to extend and retract, so that one end of the docking head can complete the docking and separation operation with the rotary joint.

[0009] As a further technical solution of this utility model, a rotary joint is sleeved on one end of the docking head, and a lifting slider is provided on one side of the rotary joint. The rotary joint and the lifting slider are movably connected through a rotating shaft. The docking head can be connected by the rotary joint to realize the movable installation of the upper rotating rod or the lower rotating rod.

[0010] As a further technical solution of this utility model, a lead screw is movably installed on the inner side of the lifting slider, and a lifting bracket is provided at the upper end of the movable base to cooperate with the upper rotating rod. By rotating the lead screw, the lead screw drives the lifting slider through the thread structure, thereby causing the lifting slider to drive the upper rotating rod to move up and down, and adjusting the distance between the lower rotating rod and the upper rotating rod.

[0011] As a further technical solution of this utility model, the lead screw is movably installed inside the lifting bracket, and the two sets of lifting brackets are symmetrically arranged.

[0012] As a further technical solution of this utility model, several sets of conveying rollers are movably installed on the lower inner side of the traction device. The several sets of conveying rollers are arranged side by side. The several sets of conveying rollers are driven by a motor and gears, so that the several sets of conveying rollers drive the cable to move and complete the traction and dragging of the cable.

[0013] As a further technical solution of this utility model, the upper end of the pressing plate is driven by two lifting rods, and several sets of pressing rollers are movably installed at the lower end of the pressing plate. The lifting rods can drive the pressing plate, so that the pressing plate drives the pressing rollers to move up and down, so that the pressing rollers press tightly against the upper surface of the cable, apply downward pressure to the cable, and press the cable tightly between the pressing rollers and the conveying rollers.

[0014] As a further technical solution of this utility model, an elastic sleeve is installed at the telescopic end of the lifting rod. The elastic sleeve is disposed between the pressure plate and the lifting rod. By using the elastic sleeve, an elastic pressing structure is formed between the pressure plate and the lifting rod, which provides elastic protection for the cable when the pressure roller comes into contact with the cable.

[0015] As a further technical solution of this utility model, the middle part of the traction device is a hollow structure, and the lower part of the movable base is provided with a drive wheel. By using the setting of two sets of guides, both ends of the traction device can be used for cable feeding or discharging operations. The drive wheel is driven by a motor and can drive the movable base to move arbitrarily.

[0016] As a further technical solution of this utility model, the outer surfaces of the lower rotating rod and the upper rotating rod are provided with limiting rings. The limiting rings are ring-shaped in whole. The setting of the limiting rings can limit the cable on both sides. By increasing the number of limiting rings, several sets of cables can be installed between the lower rotating rod and the upper rotating rod of the guide, thereby increasing the number of cables that can be pulled.

[0017] The beneficial effects of this utility model are as follows: By setting a guide, this utility model allows the cable laying traction device to flexibly adapt to cable structures of different diameters, improving its performance. During operation, the user passes the cable through the guide and traction device sequentially. By rotating the lead screw, the user drives the lifting slider via the threaded structure, which in turn drives the upper rotating rod to move up and down. Adjusting the distance between the lower and upper rotating rods allows them to clamp and fix cable structures of different sizes. A motor, in conjunction with gears, drives several sets of conveying rollers, which can be driven by the lifting rod. The clamping plate drives the clamping roller to move up and down, pressing the clamping roller tightly against the upper surface of the cable and applying downward pressure to the cable. The cable is pressed tightly between the clamping roller and the conveying roller. The elastic sleeve provides an elastic clamping structure between the clamping plate and the lifting rod, which provides elastic protection for the cable when the clamping roller contacts the cable. Together with the clamping roller fixing the upper part of the cable, several sets of conveying rollers drive the cable to move, completing the traction and dragging of the cable. The two sets of guides allow cable feeding or discharging operations at both ends of the traction device, making it flexible and applicable to cable structures of different diameters.

[0018] By setting a limiting ring, the cable laying traction device can simultaneously pull multiple cables, improving its work efficiency. During operation, the user pushes the push block, which drives the docking head to extend and retract, allowing one end of the docking head to dock with or separate from the rotary joint. This facilitates the removal of the upper or lower rotating rod. The limiting ring is then installed on the surface where the upper or lower rotating rod has been removed. The limiting ring can limit the movement of the cable on both sides. By increasing the number of limiting rings, several sets of cables can be installed between the lower and upper rotating rods of the guide, increasing the number of cables that can be pulled and preventing tilting of multiple cables during traction.

Several sets of screws 13 are movably installed on the outer surfaces of the lower rotating rod 3 and the upper rotating rod 4. A clamping device 6 is fixedly installed at the upper end of the traction device 7, and a clamping plate 16 is movably installed at the lower part of the clamping device 6. The clamping plate 16 is movably installed at the upper inner side of the traction device 7.

[0026] Both ends of the lower rotating rod 3 and the upper rotating rod 4 are equipped with docking heads 10, and one end of the docking head 10 is provided with a push block 9. By pushing the push block 9, the user can drive the docking head 10 to extend and retract, so that one end of the docking head 10 can complete the docking and separation operation with the rotary joint 11.

[0027] A rotary joint 11 is sleeved on one end of the docking head 10. A lifting slider 12 is provided on one side of the rotary joint 11. The rotary joint 11 and the lifting slider 12 are movably connected through a rotating shaft. The rotary joint 11 can be used to connect the docking head 10 to realize the movable installation of the upper rotating rod 4 or the lower rotating rod 3.

[0028] A lead screw 13 is movably installed on the inner side of the lifting slider 12. The upper end of the movable base 1 is provided with a lifting bracket 8 that works with the upper rotating rod 4. By rotating the lead screw 13, the user can drive the lifting slider 12 through the threaded structure, thereby causing the lifting slider 12 to drive the upper rotating rod 4 to move up and down, and adjust the distance between the lower rotating rod 3 and the upper rotating rod 4.

[0029] The lead screw 13 is movably installed inside the lifting bracket 8, and the two sets of lifting brackets 8 are symmetrically arranged.

[0030] Several sets of conveying rollers 5 are movably installed on the lower inner side of the traction device 7. The sets of conveying rollers 5 are arranged side by side. The motor and gears drive the sets of conveying rollers 5, so that the sets of conveying rollers 5 drive the cable to move and complete the traction and dragging of the cable.

[0031] The upper end of the pressure plate 16 is driven by two lifting rods 14, and several sets of pressure rollers 17 are movably installed at the lower end of the pressure plate 16. The lifting rods 14 can drive the pressure plate 16, so that the pressure plate 16 drives the pressure rollers 17 to move up and down, so that the pressure rollers 17 press tightly on the upper surface of the cable, apply downward pressure to the cable, and press the cable tightly between the pressure rollers 17 and the conveying rollers 5.

[0032] An elastic sleeve 15 is installed at the telescopic end of the lifting rod 14. The elastic sleeve 15 is set between the pressure plate 16 and the lifting rod 14. The elastic sleeve 15 creates an elastic pressing structure between the pressure plate 16 and the lifting rod 14, which provides elastic protection for the cable when the pressure roller 17 comes into contact with the cable.

[0033] The middle part of the traction device 7 is hollow, and the lower part of the movable base 1 is equipped with a drive wheel. With the setting of two sets of guides 2, both ends of the traction device 7 can be used for cable feeding or discharging.

By increasing the number of limiting rings 18, several sets of cables can be installed between the lower rotating rod 3 and the upper rotating rod 4 of the guide 2, thereby increasing the number of cables that can be pulled.

[0035] A cable laying traction device, in use, by incorporating a guide 2, allows for flexible adaptation to cable structures of different diameters, improving its performance. During operation, the user sequentially passes the cable through the guide 2 and the traction device 7. By rotating the lead screw 13, the user drives the lifting slider 12 via its threaded structure. This lifting slider 12 then drives the upper rotating rod 4 up and down, adjusting the distance between the lower rotating rod 3 and the upper rotating rod 4. This allows the lower rotating rod 3 and the upper rotating rod 4 to clamp and secure cables of different sizes. A motor, in conjunction with gears, drives several sets of conveying rollers 5, and the lifting rod 14 drives the pressure plate. 16, causing the pressure plate 16 to drive the pressure roller 17 to move up and down, so that the pressure roller 17 presses tightly against the upper surface of the cable, applying downward pressure to the cable, so that the cable is pressed tightly between the pressure roller 17 and the conveying roller 5. With the setting of the elastic sleeve 15, there is an elastic pressing structure between the pressure plate 16 and the lifting rod 14. When the pressure roller 17 contacts the cable, it plays an elastic protection role for the cable. In conjunction with the fixing of the upper part of the cable by the pressure roller 17, several sets of conveying rollers 5 drive the cable to move, completing the traction and dragging of the cable. With the setting of two sets of guides 2, both ends of the traction device 7 can perform cable feeding or discharging operations, flexibly adapting to cable structures of different diameters.

[0036] By setting the limiting ring 18, the cable laying traction device can simultaneously perform traction operations on multiple cables, improving its working efficiency. During operation, the user pushes the push block 9, which drives the docking head 10 to extend and retract, allowing one end of the docking head 10 to complete the docking and separation operation with the rotary joint 11. This facilitates the removal of the upper rotating rod 4 or the lower rotating rod 3, and the installation of the limiting ring 18 on the removed surface of the upper rotating rod 4 or the lower rotating rod 3. The limiting ring 18 can limit the movement of the cable on both sides. By increasing the number of limiting rings 18, several sets of cables can be installed between the lower rotating rod 3 and the upper rotating rod 4 of the guide 2, increasing the number of cables that can be pulled and preventing tilting of multiple cables during traction.
