Description

Technical Field

[0001] This application relates to the technical field of cable construction equipment, and in particular to an adjustable angle extraction device. Background Technology

[0002] During cable laying and maintenance, cable retrieving equipment is often used to retrieve cables from cable reels. Most existing cable retrieving equipment has a fixed structure and a single retrieving direction, making it impossible to flexibly adjust the retrieving angle according to the actual construction environment and needs. When the cable laying path is complex, such as when retrieving cables at corners, in confined spaces, or at different heights, traditional equipment is insufficient. This not only increases the difficulty of construction and reduces efficiency but may also cause damage to the cable due to improper angles, such as wear and excessive bending, affecting the cable's service life and electrical performance.

[0003] A search revealed that Chinese Patent Publication No. CN222720138U discloses a wire and cable buffer take-up twisted pair cabling machine, which includes a fixing plate; a connecting column is fixedly connected to one side of the top of the fixing plate, a heating component is fixedly connected to the surface of the connecting column, and three sets of lubrication components are fixedly connected to the top of the fixing plate. The lubrication components include a lubrication box, and the bottom of the lubrication box is fixedly connected to the top of the fixing plate.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: the existing extraction devices have low degrees of freedom in adjustment, making it difficult to adapt to complex cable laying paths. In order to solve the problem of low degrees of freedom in the existing extraction devices, this application has set up multiple angle adjustment structures, thereby enabling the extraction devices to better adapt to complex cable laying paths by virtue of their flexible angle adjustment function, height adjustment function, and cable protection design. Utility Model Content

[0005] To address the issue of low angular freedom in existing extraction devices, this application provides an adjustable-angle extraction device.

[0006] This application provides an adjustable angle extraction device, employing the following technical solution: It includes a base plate, on which an angle adjustment mechanism, a lead wire mechanism, and a cable reel are mounted; the angle adjustment mechanism includes a turntable rotatably connected to the base plate and a first support mounted on the turntable; the first support includes two vertical rods mounted on the turntable and a horizontal rod fixedly connected to the two vertical rods, with an adjustment assembly slidably connected to the two vertical rods; the adjustment assembly includes a slider slidably connected to each vertical rod, each slider rotatably connected to a rotating frame, and the two rotating frames are connected by two first rotating rollers, the end face of each first rotating roller rotatably connected to the corresponding rotating frame; a brake assembly is mounted on the rotating frame, enabling multi-axis adjustment of the lead wire mechanism via the angle adjustment mechanism.

[0007] Optionally, each vertical rod is provided with a sliding groove, and the slider is slidably connected to the corresponding sliding groove.

[0008] Optionally, a lead screw is rotatably installed in one of the slides, and the corresponding slider has a threaded hole that matches the lead screw.

[0009] Optionally, the crossbar is provided with a rotating through hole, and a crank is rotatably connected inside the rotating through hole. One end of the crank is fixedly connected to one end of the lead screw.

[0010] Optionally, a support is provided on the base plate, and a worm gear is rotatably connected to the support.

[0011] Optionally, a worm wheel that meshes with the worm is coaxially fixed on the lower end face of the turntable, and the lower end face of the worm wheel is rotatably connected to the base plate.

[0012] Optionally, the lead wire mechanism includes a second bracket mounted on the base plate. The second bracket has an inverted U-shaped structure, and two second rotating rollers are rotatably connected to the two inner walls of the second bracket.

[0015] Optionally, a pull rod is provided on the peripheral wall of the brake lever, which facilitates the operator to lift the brake lever.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] 1. This utility model utilizes the cooperation of a worm gear and a worm wheel. Rotating the worm gear drives the turntable to rotate, achieving angle adjustment of the entire instrument and meeting the needs of cable extraction in different directions. The slider in the adjustment assembly can slide on the vertical rod. Turning the crank causes the lead screw to raise and lower the slider, changing the height of the adjustment assembly. The rotating frame can rotate flexibly and is equipped with a brake assembly, which can be fixed in time after the angle is adjusted, facilitating cable extraction operations at different heights and angles.

[0018] 2. This utility model features two second rotating rollers within the second bracket of the cable guide mechanism. When the cable passes through, these second rotating rollers effectively reduce friction during cable lead-in. The guide posts on the base plate not only guide the cable, but also allow the cable to rotate around the guide posts as fulcrums when the turntable angle is adjusted. Furthermore, the rotatable guide posts further reduce friction on the cable, preventing wear and tear and ensuring cable quality and lifespan. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-6This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0027] This application discloses an adjustable-angle extraction device. For example... Figure 1 As shown, the device includes a base plate 1, on which an angle adjustment mechanism and a lead wire mechanism are provided. The angle adjustment mechanism includes a turntable 2 rotatably connected to the base plate 1 and a first support 3 disposed on the turntable 2. The first support 3 includes two vertical rods 4 disposed on the turntable 2 and a horizontal rod fixedly connected to the two vertical rods 4. The two vertical rods 4 are slidably connected to an adjustment assembly. The adjustment assembly includes a slider 5 slidably connected to each vertical rod 4. Each slider 5 is rotatably connected to a rotating frame 6. The two rotating frames 6 are connected by two first rotating rollers 7. The end face of each first rotating roller 7 is rotatably connected to the corresponding rotating frame 6. A brake assembly is provided on the rotating frame 6.

[0028] In this embodiment, the base provides stable support for the entire device. Multiple casters can be installed at the bottom of the base to facilitate the movement of the device on the construction site. The casters are equipped with brakes to fix the device after reaching the designated position. The base can also be equipped with leveling feet to level the device on uneven ground and ensure the stability of the device during operation.

[0029] The wire ends on the cable reel pass through the lead-in mechanism, then through the position between the two first rotating rollers 7, and finally reach the position where the work is required.

[0030] When the working angle needs to be adjusted, the height of the adjusting component is changed by changing the height of the slider 5; the rotating frame 6 is rotated to face different directions, and the rotating frame 6 is fixed by the brake component.

[0031] Please see Figure 1 Each vertical rod 4 is provided with a sliding groove 8, and the slider 5 is slidably connected to the corresponding sliding groove 8; a lead screw 9 is rotatably provided in one of the sliding grooves 8, and the corresponding slider 5 is provided with a threaded hole adapted to the lead screw 9; a rotating through hole is provided on the horizontal rod, and a crank handle 10 is rotatably connected in the rotating through hole, and one end of the crank handle 10 is fixedly connected to one end of the lead screw 9.

[0032] In this embodiment, by turning the crank handle 10, the lead screw 9 is rotated, thereby causing the corresponding slider 5 to drive the adjustment mechanism to move up or down.

[0033] Please see Figure 4A support 11 is provided on the base plate 1, and a worm gear 12 is rotatably connected to the support 11. A worm wheel 13 that meshes with the worm gear 12 is coaxially fixed on the lower end face of the turntable 2, and the lower end face of the worm wheel 13 is rotatably connected to the base plate 1.

[0034] In this embodiment, by setting up the worm gear 13 and the worm 12, when the overall angle needs to be adjusted, the worm gear 12 is rotated to drive the worm gear 13 to rotate the turntable 2, thereby causing the components on the turntable 2 to rotate accordingly.

[0035] Please see Figure 1 The lead wire mechanism includes a second bracket 14 disposed on the base plate 1. The structure of the second bracket 14 is inverted U-shaped, and two second rotating rollers 15 are rotatably connected to the two inner walls of the second bracket 14.

[0036] In this embodiment, the position where the cable passes between the two second rotating rollers 15 can reduce friction when the cable is led out.

[0037] Please see Figure 1 Two guide posts 16 are provided on the base plate 1;

[0038] In this embodiment, the cable passes through the position between the two guide posts 16. When the turntable 2 is adjusted in angle, the cable can rotate with the turntable 2 with the corresponding guide post 16 as the fulcrum.

[0039] In this implementation, each guide post 16 can also be rotatably connected to the base plate 1 to further reduce the friction force on the cable.

[0040] Please see Figure 5 The brake assembly includes a stand 17 fixedly mounted on the slider and a sleeve 18 mounted on the stand 17; a brake rod 19 is slidably connected inside the sleeve 18, a brake pad 20 is provided at one end of the brake rod 19, and a spring 21 is provided between the other end of the brake rod 19 and the bottom wall of the sleeve 18; a pull rod 22 is provided on the peripheral wall of the brake rod 19.

[0041] In this embodiment, the released spring can drive the brake lever 19 to move downward, thereby enabling the brake pad 20 to press against the rotating frame 6.

[0042] The implementation principle of an adjustable angle extraction device according to an embodiment of this application is as follows:

[0043] At the construction site, use the casters at the bottom of the equipment to move it to the designated position and fix the equipment by using the brakes on the casters; if the ground is uneven, use the leveling feet to level it and ensure the equipment works stably.

[0044] The cable end on the cable reel is passed sequentially between the two second rotating rollers 15 of the cable lead-in mechanism, then between the two guide posts 16 and the two first rotating rollers 7 in the angle adjustment mechanism, and then connected to the position where it needs to work. During this process, the second rotating rollers 15 can reduce the friction when the cable is led in, which helps to smoothly lead the cable.

[0045] When the working height needs to be adjusted, turn the crank 10 on the crossbar, and the crank 10 will drive the lead screw 9 to rotate. Since the threaded hole on the slider 5 is compatible with the lead screw 9, the rotation of the lead screw 9 will cause the slider 5 to slide up and down in the groove 8 of the vertical bar 4, thereby driving the adjustment component to rise or fall and change its height.

[0046] When the working angle needs to be adjusted, pull the lever upward and then rotate the rotating frame 6 to make the rotating frame 6 face the required direction to meet different construction angle requirements; after the angle adjustment is completed, the brake lever in the brake assembly slides downward under the drive of the spring in the sleeve, and the brake pad at one end presses the rotating frame 6 to ensure that the rotating frame 6 is fixed and stable, and to prevent the angle from changing during the cable lead-out process;

[0047] When overall angle adjustment is required, the worm gear 12, which is rotatably connected to the support 11, is rotated. The worm gear 12 drives the meshing worm wheel 13 to rotate. The worm wheel 13 is coaxially fixed with the turntable 2, thereby causing the turntable 2 to drive the components on it to rotate together, achieving overall angle adjustment. During the rotation of the turntable 2, the cable passing between the two guide posts 16 will rotate with the guide posts 16 as the fulcrum. Moreover, if the guide posts 16 are rotatably connected to the base plate 1, the friction force on the cable can be further reduced.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
