Description

Technical Field

[0001] The invention relates to an improvement of a cable reeling and unreeling technology, belongs to the field of electric power engineering, and in particular relates to a cable unreeling device. Background Art

[0002] Since the 20th century, electricity production has primarily relied on thermal power plants, hydropower stations, and nuclear power plants. Where conditions permit, tidal, geothermal, and wind energy are also used for power generation. The transmission and distribution of electricity is primarily achieved through high- and low-voltage AC power networks. The development of power transmission engineering technology focuses on research into ultra-high voltage (over 1 million volts) AC and DC transmission technologies to form larger power networks. Research is also underway on the technical aspects of superconductor power transmission. The large-scale power system that emerged in the 20th century integrated power generation, transmission, transformation, distribution, and consumption into an organic whole, becoming the physical engineering system with the widest spatial span, strict time coordination, and extremely complex hierarchical division of labor in the social material production sector. In power engineering, cables are wound on cable drums for transportation, and the cable is usually reeled in and out by cable drums. The existing cable drums can perform the work well, but some shortcomings have been found during use. During the reeling process, since the cables are erected on the ground, although they are manually straightened, the reeling motor will still cause the cables to be reeled in relatively loosely when working, and cannot be restored to the initial tight state. Under the bumps during transportation, the entire reel is prone to loosening, making it inconvenient to pick up and release the cables.

[0003] A Chinese patent application with application number CN202110930230.8 and application date August 13, 2021 discloses a cable release for power construction. The cable release for power construction includes a box-type base with a hollow structure. The base includes a bottom plate and a top plate. The first bracket and the second bracket are symmetrically arranged on the left and right sides of the upper surface of the top plate. The first bracket and the second bracket both have a vertical part and a horizontal part, and are both in an inverted L shape. The bottoms of the vertical parts of the first bracket and the second bracket are fixedly connected to the upper surface of the top plate. The horizontal part of the first bracket is rotatably connected to the first screw, and the horizontal part of the second bracket is rotatably connected to the second screw. The first screw and the second screw respectively pass through the holes set on the top plate and extend vertically to the interior of the box-type base. The first screw and the second screw can rotate in the holes set on the top plate, but the above solution does not solve the problem that the cable is prone to loosening and instability during the winding process.

[0056] The principle of the present invention is described as follows:

[0057] The driving motor 18 drives the gear 19 to rotate, and the gear ring 17 drives the rotating sleeve 3 to rotate after the rotation of the gear ring 17, and then drives the baffle 13 to rotate, thereby realizing the work of reeling and releasing the line. When the cable 39 is wound around the rotating sleeve 3, the upper arc end 261 and the lower arc end 262 on the arc-shaped extrusion block 26 are in an arc shape. In this way, when the cable 39 contacts it, it will slide into the arc groove 263 of the arc-shaped extrusion block 26, and thus be wound layer by layer. When the arc-shaped extrusion block 26 is squeezed, the spring 2 38 is compressed by force. At the same time, due to the elastic force of the spring 2 38, the cable 39 is squeezed into the arc-shaped extrusion block 26, so that the cable 39 is further fixed, thereby ensuring stability and reliability without loosening.

[0058] When the device is performing the line-releasing operation, the corresponding pressure blocks 28 are opened in turn to perform the line-releasing operation, which can avoid the remaining cables from becoming tangled. At the same time, when the line-reeling operation is performed, the line is first wound on one side in turn. After the winding is completed, the corresponding pressure block 28 is pressed down, and then the line is wound again. In this way, the line is wound in batches and the arc-shaped extrusion block 26 is used to limit the wound cable. The back and forth sliding of the slide bar 10 is used to control the expansion and retraction of the corresponding cross arm 15, so that the cable remains taut, thereby making the line-reeling operation simple and easy, and the winding effect is good, and there will be no tangled or loose situation. Example

[0059] A cable release, comprising a bracket 1, a central shaft 2, a rotating sleeve 3, a rotating ring 7, a baffle 13 and a cross arm 15; the bracket 1 is axially mounted with the central shaft 2, the side of the central shaft 2 is connected to the inner periphery of the rotating sleeve 3, and two baffles 13 are sleeved on the side of the rotating sleeve 3, each baffle 13 is slidably connected to a plurality of cross arms 15, and the plurality of cross arms 15 are distributed in an annular shape on the baffle 13; the side of the bracket 1 is located on the upper and lower sides of the central shaft 2 and is slidably fitted with two adjustment brackets 4, the two side faces of the adjustment bracket 4 are respectively threadedly fitted with two adjustment rods 5, and one end of each adjustment rod 5 Both pass through the adjustment frame 4 and are connected to the side of the bracket 1; the opposite sides of the two adjustment frames 4 are connected to a trapezoidal adjustment cover 6, the inner wall of each adjustment cover 6 is provided with a rotating ring 7 connected in rotation, and the inner wall of the rotating ring 7 is provided with multiple groups of partitions 8; two groups of spring cylinders 9 are installed on the side of the rotating sleeve 3, and a slider 11 is slidably connected in each spring cylinder 9. One side of each slider 11 is connected to one end of the slide rod 10, and the other end of the slide rod 10 passes through the baffle 13 and is connected to the baffle 13, the other end of the slider 11 is connected to one end of the spring 12, and the other end of the spring 12 is connected to the spring cylinder 9 is connected to the inner wall side of the slider 11, and the other side of the slider 11 passes through the spring tube 9 and is slidably connected to the corresponding baffle 13; the top of the cross arm 15 is provided with multiple upper baffles 231, and the bottom of the cross arm 15 is provided with multiple lower baffles 23, and the cable 39 is arranged between the longitudinal upper baffle 231 and the lower baffle 23; the top of the bracket 1 is evenly plugged with multiple threaded rods 29, and the bottom ends of all the threaded rods 29 pass through the top of the bracket 1 and are connected to the top of the pressure block 28 through a bearing. The top of the pressure block 28 is located on the side of the threaded rod 29 and is connected to the bottom of the guide rod 30. The top of the guide rod 30 passes through The top of the bracket 1 is set vertically, and there is a gap between the guide rod 30 and the threaded rod 29, which ensures the normal lifting and lowering of the pressure block 28. At the same time, a guide rod 30 is fixedly connected to the top of each pressure block 28, and the top of each guide rod 30 passes through the top of the bracket 1 and is slidably connected thereto, which ensures the stability of the lifting and lowering of the pressure block 28, avoids left and right sliding, and positioning errors. When the pressure block 28 drops, it will press on the cable 39, so that the cable will not leave the current area and avoid loosening. In this way, even if driving on a bumpy road, the cable reel will not become loose.

[0060] When in use: the driving motor 18 drives the gear 19 to rotate, and the gear ring 17 rotates, and the gear ring 17 rotates, and the rotating sleeve 3 rotates, and then drives the baffle 13 to rotate, so as to realize the work of winding and releasing the line. When the cable 39 is wound on the rotating sleeve 3, when the cable 39 contacts the arc-shaped extrusion block 26, it slides into the arc-shaped extrusion block 26, and is wound layer by layer. The distance between the two adjustment covers 6 is adjusted by the adjustment frame 4. The two baffles 13 and the rotating sleeve 3 together form a winding drum, so that the cable can be stored. The cross arm 15 plays the role of tightening the cable, so that even if the cable is loose in the initial state, it can be adjusted by adjusting The rod 5 increases the distance between the two adjustment covers 6, so that the cross arm 15 is no longer restricted and expands outward, achieving the purpose of tightening the cable, so that the cable is no longer loose and the line-winding work can be completed. The slider 11 plays a limiting role to prevent the slide bar 10 from disengaging from the spring tube 9. The back and forth sliding of the slide bar 10 is used to control the expansion and retraction of the corresponding cross arm 15. At the same time, the spring 12 set in the spring tube 9 is used to utilize the elastic force of the slider 11 to achieve the purpose of sliding the slide bar 10, thereby expanding the cross arm 15. When the adjustment rod 5 is adjusted to reduce the distance between the two adjustment covers 6, the cross arm 15 will shrink inward, thereby ensuring the normal operation. Example

[0061] Example 2 is basically the same as Example 1, except that:

[0062] A cable release, wherein a guide groove 27 is provided in the upper baffle 231, and the guide groove 27 is L-shaped; a hollow groove 232 is provided inside the lower baffle 23, and a slider 24 is slidably connected in the hollow groove 232, one side of the slider 24 is connected to one side of the sliding plate 25, and the other end of the sliding plate 25 is connected to the side of the arc-shaped extrusion block 26, and the sliding plate 25 slides with the lower baffle 23, and the other side of the slider 24 is connected to one end of the spring 238, and the other end of the spring 238 is connected to the inner wall of the hollow groove 232, and an arc groove 263 is provided on the side of the arc-shaped extrusion block 26, and the top and bottom of the arc-shaped extrusion block 26 are respectively provided with an upper arc end 261 and a lower arc end 262, and the cable 39 is arranged in the placement area 264 formed by the arc groove 263, the upper arc end 261 and the lower arc end 262.

[0063] When in use: the guide groove 27 is L-shaped, so that after each layer of cable 39 is wound, the control cable 39 is extended into the guide groove 27, thereby re-entering the bottom of another layer, so that the winding work can continue. The remaining sliders 24 limit the position of the sliding plate 25 to avoid falling off. When the cable 39 contacts the arc-shaped extrusion block 26, it will slide into the arc groove 263 of the arc-shaped extrusion block 26, so that it is wound layer by layer. When the arc-shaped extrusion block 26 is squeezed, the spring 2 38 is compressed by force, thereby ensuring that the cable is squeezed into the arc-shaped extrusion block 26, so that the cable is further fixed, thereby ensuring stability and reliability without loosening. Example

[0064] Example 3 is basically the same as Example 1, except that:

[0065] A cable release, wherein a bearing 51 is installed on the side of the bracket 1 corresponding to the adjusting rod 5, and the adjusting rod 5 is connected to the bearing 51 after passing through the adjusting frame 4; a T-shaped pull rod 36 is slidably inserted on the adjusting frame 4, and the bottom end of each T-shaped pull rod 36 is connected to the top of the threaded rod 2 35, and the bottom end of the threaded rod 2 35 passes through the adjusting frame 4 and is movably connected to the top of the L-shaped top rod 31; the left end top of the L-shaped top rod 31 is connected to the bottom of the brake block 34, and the top of the brake block 34 contacts the rotating ring 7, and the right end top of the L-shaped top rod 31 is connected to the bottom of the telescopic rod 33, and the top of the telescopic rod 33 is sleeved with a telescopic cylinder 32, and the top of the telescopic cylinder 32 is connected to the inner top wall of the adjusting frame 4.

[0066] When in use: when the T-shaped pull rod 36 is pulled upward, the L-shaped top rod 31 will rise. At the same time, after slightly rotating the T-shaped pull rod 36, the threaded rod 2 35 can be fixed to the adjusting frame 4 through the thread, thereby freeing the operator's hands. A brake block 34 is fixedly connected to the top end of each L-shaped top rod 31, and each brake block 34 is set at the corresponding rotating ring 7. In this way, when the L-shaped top rod 31 rises, the brake block 34 will also rise accordingly, thereby contacting the rotating ring 7 to form a brake. This can protect the drive motor 18 and avoid damage to the gear ring 17 due to inertia. The cable drum is very heavy as a whole. Secondly, during transportation, due to bumps and shaking, the baffle 13 will rotate, thereby causing damage to the drive motor 18 in the shutdown state. The telescopic rod 33 and the telescopic cylinder 32 can play a guiding role, so that the braking work can be carried out more stably.

[0067] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
