Description

Technical Field

[0001] The utility model relates to the technical field of cable winding and unwinding, in particular to a portable cable winding and unwinding device for electric power construction. Background Technique

[0002] Electric power construction cables play a crucial role in the construction and maintenance of the power system. There are various types of electric power construction cables. Common ones include power cables and overhead conductors. Power cables are usually used for underground laying, with good insulation performance and protection performance, which can effectively reduce the influence of the external environment on power transmission. Overhead conductors are mostly used for overhead lines, with high mechanical strength and electrical conductivity. The quality of these cables is directly related to the stability and safety of power transmission. High-quality electric power construction cables should have good electrical conductivity, heat resistance, corrosion resistance and insulation performance. Usually, in order to facilitate transportation and storage, cable drums are used for winding.

[0003] For existing cable winding and unwinding devices, most of them use a solid fixed frame as the basic support structure. A reel for winding and unwinding cables is placed on the fixed frame. The reel is usually made of high-strength metal materials, with sufficient strength and durability to cope with frequent cable winding and unwinding operations. Then, a manual or electric method is used to drive the reel to rotate, so as to wind and unwind the cables.

[0004] However, for existing cable winding and unwinding devices, their fixed frames are relatively large, which makes the whole device bulky and unable to be moved conveniently. Especially in the case of frequently changing working locations, this inconvenient mobility greatly affects the work efficiency. At the same time, when winding, the existing devices lack effective fixation of one end of the cable, which easily causes the cable to slide during the winding process, resulting in winding failure. This situation not only wastes time and manpower, but also may damage the cable. Therefore, a portable cable winding and unwinding device for electric power construction is proposed to solve the above problems. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a portable cable winding and unwinding device for electric power construction, aiming to improve the problem that one end of the cable is not fixed during winding and unwinding in the prior art, which easily causes winding failure and scattering, resulting in the inability to wind and unwind conveniently and quickly.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A portable cable winding and unwinding device for electric power construction, including a placement rack. A fixing plate is fixedly connected to the outer wall of the placement rack. A rotating plate is fixedly connected to the outer wall of the placement rack. A winding drum is rotatably connected inside the rotating plate. Rotating handles are fixedly connected to both sides of the outer wall of the winding drum. A placement groove is formed inside the winding drum. A sliding groove is formed inside the winding drum. A clamp is fixedly connected inside the winding drum. A connecting plate is fixedly connected inside the winding drum. A first sliding column is arranged inside the winding drum. A first spring is sleeved on the outer wall of the first sliding column. One end of the first spring is fixedly connected to the outer wall of the other clamp, and the other end of the first spring is fixedly connected to the inner wall of the winding drum. A sliding block is fixedly connected to the outer wall of the first sliding column. The outer wall of the sliding block is slidably connected inside the sliding groove. The inner wall of the sliding block is slidably connected to the outer wall of the connecting plate. A moving component is arranged on the outer wall of the placement rack, and the moving component is used to move the placement rack;

[0009] The moving component includes corner pads and wheels. The inner wall of the corner pads is fixedly connected to the outer wall of the placement rack, and the outer wall of the wheels is rotatably connected to the outer wall of the placement rack;

[0010] As a further description of the above technical solution:

[0011] Rotating teeth are fixedly connected to the outer wall of the winding drum, and the outer wall of the rotating teeth is rotatably connected inside the fixing plate;

[0012] As a further description of the above technical solution:

[0013] A fixing block is fixedly connected to the outer wall of the fixing plate. A second sliding column is slidably connected inside the fixing block. A second spring is sleeved on the outer wall of the second sliding column;

[0014] As a further description of the above technical solution:

[0015] The top of the second spring is fixedly connected to the bottom of the fixing block, and the bottom of the second spring is fixedly connected to the top of a baffle;

[0021] The outer wall of the connection block is slidably connected to the inside of the limiting groove, the outer wall of the rotating column is fixedly connected with a paddle, and the outer wall of the rotating column is fixedly connected with a card.

[0022] The utility model has the following beneficial effects:

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Referring to Figure 1 and Figure 2 , an embodiment provided by the present invention: a portable cable winding and unwinding device for electric power construction, including a placement rack 1, a fixed plate 2 fixedly connected to the outer wall of the placement rack 1, a rotating plate 5 fixedly connected to the outer wall of the placement rack 1, a winding drum 3 rotatably connected inside the rotating plate 5, turning handles 4 fixedly connected to both sides of the outer wall of the winding drum 3, a placement groove 9 opened inside the winding drum 3, a sliding groove 13 opened inside the winding drum 3, a clamp 8 fixedly connected inside the winding drum 3, a connecting plate 12 fixedly connected inside the winding drum 3, a first sliding column 10 arranged inside the winding drum 3, a first spring 14 sleeved on the outer wall of the first sliding column 10, one end of the first spring 14 fixedly connected to the outer wall of the other clamp 8, the other end of the first spring 14 fixedly connected to the inner wall of the winding drum 3, a slider 11 fixedly connected to the outer wall of the first sliding column 10, the outer wall of the slider 11 slidably connected inside the sliding groove 13, and the inside of the slider 11 slidably connected to the outer wall of the connecting plate 12. A moving component is arranged on the outer wall of the placement rack 1, and the moving component is used to move the placement rack 1.

[0032] Specifically, push the slider 11, drive the first sliding column 10 to move through the slider 11, then drive the clamp 8 to move through the first sliding column 10, then compress the first spring 14 through the clamp 8, then put one end of the cable into the placement groove 9, and then release the slider 11. The first spring 14 rebounds to drive the clamp 8 to fix the cable, which is convenient for clamping and fixing, facilitating winding. At the same time, when releasing, it can prevent excessive unwinding and dropping, enabling a smoother winding operation. There is no need to spend extra time and effort to organize the cable end, thus accelerating the winding speed. Moreover, the stability during winding is enhanced. The fixed cable end reduces the possible shaking and deviation of the cable during winding, reducing winding failures or accidents caused by cable instability. At the same time, the working safety is greatly improved during release. The fixed cable end can effectively prevent the cable from suddenly swinging greatly or flying off during release, reducing the risk of accidental injury to operators and the surrounding environment.

[0033] Referring to Figure 1 , the moving component includes a corner pad 6 and wheels 7. The inside of the corner pad 6 is fixedly connected to the outer wall of the placement rack 1, and the outer wall of the wheels 7 is rotatably connected to the outer wall of the placement rack 1.

[0034] Specifically, the device can be moved by tilting the placement rack 1 through the rotating wheels 7 at the bottom, and then the placement rack 1 is straightened and the device is fixed by the corner pad 6 at the other end. At the same time, the corner pad 6 is made of rubber and plays a certain buffering role.

[0035] Reference Figure 1 and Figure 3 The outer wall of the reel 3 is fixedly connected with a rotating tooth 15, and the outer wall of the rotating tooth 15 is rotatably connected to the inside of the fixed plate 2, and the outer wall of the fixed plate 2 is fixedly connected with a fixed block 20, and the fixed block 20 is slidably connected with a sliding column 19, and the outer wall of the sliding column 19 is sleeved with a spring 18, and the top of the spring 18 is fixedly connected to the bottom of the fixed block 20, and the bottom of the spring 18 is fixedly connected with the top of a baffle 17, and the top of the baffle 17 is fixedly connected to the bottom of the sliding column 19, and the bottom of the baffle 17 is fixedly connected with a card block 16, and the outer wall of the card block 16 is slidably connected to the inside of the rotating tooth 15, and a limiting groove 21 is opened inside the fixed plate 2, and the outer wall of the fixed plate 2 is rotatably connected with a rotating column 23, and the outer wall of the rotating column 23 is fixedly connected with a connecting block 22, and the outer wall of the connecting block 22 is slidably connected to the inside of the limiting groove 21, and the outer wall of the rotating column 23 is fixedly connected with a paddle 24, and the outer wall of the rotating column 23 is fixedly connected with a card 25.

[0036] Specifically, pull the slide post 19, and the baffle 17 is lifted by the slide post 19, and then the card block 16 is lifted by the baffle 17, and at the same time, the spring 18 is compressed by the baffle 17 to the bottom surface of the card 25. Since the contact surfaces of the two are inclined surfaces, the card 25 is driven to rotate to its top. After that, since the weight of the card 25 is greater than the paddle 24, the card 25 returns to its original position, and then rotates inside the limiting groove 21 through the connecting block 22. Since the limiting groove 21 is 90 degrees, the connecting block 22 can be limited in angle, so that the card 25 is parallel to the baffle 17, thereby fixing the baffle 17 to prevent it from falling, and the reel 3 is rotated by the second rotatable gear 15. When it needs to stop, the paddle 24 is pulled to drive the rotating column 23 to rotate, and then the card 2 is driven by the rotating column 23. 5 is rotated to push the baffle 17 to rise, and when the rotation angle is greater than the length of the baffle 17, the baffle 17 is driven to descend through the rebound of the spring 18, thereby driving the clamping block 16 to slide to the inside of the rotating tooth 15 for locking, thereby improving the safety of operation. When it is necessary to stop the rotation of the drum 3, such as for maintenance, inspection or replacement of cables, the drum 3 can be quickly locked to prevent personal injury or equipment damage caused by accidental rotation. Secondly, the controllability of the work is enhanced. According to the actual work progress and needs, the operator can flexibly choose to lock or release the rotation of the drum 3 to better control the cable retracting and releasing process. In addition, the convenience is improved. The operator does not need to spend too much time and energy to take complicated measures to control the rotation of the drum 3, which saves operation time and operation and speeds up the entire construction process.

[0037] Working principle: Push the slider 11, drive the fixed first slide post 10 to slide inside the sliding groove 13 through the slider 11, then drive the connected fixture 8 to move through the first slide post 10, and at the same time compress the first spring 14 fixed to the fixture 8. Then place one end of the cable between the two fixtures 8 through the placement groove 9, and then release the slider 11. Drive the fixture 8 to return through the rebound of the first spring 14, so as to fix one end of the cable through the two fixtures 8. Then pull the second slide post 19, drive the bottom-fixed baffle 17 to rise through the second slide post 19, and then drive the bottom-fixed block 16 to rise through the baffle 17. At the same time, compress the second spring 18 connected to the top through the baffle 17 until the bottom of the card 25. Then push the card 25 through the baffle 17 to its top. Then release the second slide post 19, and fix the baffle 17 through the flat surface of the top of the card 25 to prevent it from falling. Thus, the reel 3 can be rotated to wind and unwind the cable. When stopped, the dial 24 can be toggled, and the rotating column 23 connected to the dial 24 rotates. Then drive the fixed card 25 to rotate through the rotating column 23. When the angle exceeds the length of the baffle 17, drive the baffle 17 to fall through the rebound of the second spring 18, so as to drive the block 16 to fall into the internal gear 15 to lock it. Then release the dial 24. Since the connecting block 22 connected to the outer wall of the rotating column 23 slides inside the limiting groove 21, the rotation angle of the rotating column 23 is limited.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
