[0001] The invention belongs to the technical field of cable reels, and in particular relates to an adjustable retractable cable reel. Background Art

[0002] The cable reel is a cable winding device that provides power supply, control power supply or control signal for large mobile equipment. In the process of power engineering construction, the reeling and releasing of power cables is essential, but the existing cable reels cannot adjust the reeling amount according to the actual length of the power cable used in actual engineering use, resulting in the need to reel the power cable in sections during the construction process, affecting the construction efficiency; in addition, some cable reels have a complicated arrangement for the reeling and releasing of cables, which can easily cause the cable to become loose or entangled when it is reeled and released, making it inconvenient to use and unable to ensure that the cable is always in a taut state during the reeling and releasing process.

[0005] Further, the fixed expansion mechanism comprises a fixed telescopic rod, a horizontal telescopic rod, a first tilting rod, a second tilting rod, a third tilting rod, a fourth tilting rod and a sliding rack, the fixed telescopic rod is vertically arranged on the base, the winding column passes through the telescopic end of the fixed telescopic rod, the first tilting rod and the second tilting rod are symmetrically and tiltedly arranged on both sides of the fixed telescopic rod, the horizontal telescopic rod is horizontally and symmetrically connected to the telescopic end of the fixed telescopic rod, the horizontal telescopic rod is symmetrically arranged on both sides of the winding column, a sliding frame is vertically arranged on the telescopic end of the fixed telescopic rod, the sliding frame is opened toward the hydraulic telescopic column, the sliding frame is arranged above the winding column, the sliding rack is slidably arranged in the sliding frame, and the third tilting rod and the fourth tilting rod are symmetrically and tiltedly arranged at the upper end of the sliding rack; Preferably, the first tilt rod, the second tilt rod, the third tilt rod and the fourth tilt rod are telescopic rod structures, the first tilt rod and the second tilt rod are perpendicular to each other, the third tilt rod and the fourth tilt rod are perpendicular to each other, the telescopic end of the first tilt rod and the telescopic end of the third tilt rod are perpendicular to each other, the telescopic end of the second tilt rod and the telescopic end of the fourth tilt rod are perpendicular to each other, the telescopic end of the first tilt rod and the telescopic end of the third tilt rod are connected to the telescopic end of one of the horizontal telescopic rods, and the telescopic end of the second tilt rod and the telescopic end of the fourth tilt rod are connected to the telescopic end of another of the horizontal telescopic rods; the first tilt rod, the second tilt rod, the third tilt rod and the fourth tilt rod are connected to form a square structure, and the fixed telescopic rod, the sliding rack and the symmetrical horizontal telescopic rods are the diagonals of the square; Further, the transition mechanism includes a vertical plate bracket and a transition gear, the vertical plate bracket is vertically arranged on the hydraulic telescopic column, the vertical plate bracket is arranged between the telescopic end of the hydraulic telescopic column and the sliding rack, the inner side of the vertical plate bracket is provided with a fixed rack, the teeth of the fixed rack face the sliding rack, the transition gear is rotatably arranged on the side wall of the sliding frame, the transition gear is rotatably arranged on the inner side of the vertical plate bracket, the transition gear is arranged between the fixed rack and the sliding rack, and the transition gear is meshed with the fixed rack and the sliding rack respectively; When the output end of the hydraulic telescopic column drives the fixed telescopic rod to stretch, the horizontal telescopic rod and the sliding frame are pushed upward, and the telescopic ends of the first tilting rod and the second tilting rod are pulled to move obliquely upward, so that the telescopic ends of the horizontal telescopic rod follow and extend to both sides, and the sliding frame moves upward relative to the vertical plate bracket, so that the transition gear moves upward and meshes with the fixed rack to rotate, and the transition gear meshes with the sliding rack at the same time to drive the sliding rack to move upward, and then pull the third tilting rod and the fourth tilting rod to move upward. Under the restriction of the horizontal telescopic rod, the third tilting rod and the fourth tilting rod are extended, so as to achieve the technical effect that the lower end of the fixed telescopic rod, the upper end of the sliding rack and the telescopic end point of the horizontal telescopic rod are respectively extended to four directions with the winding column as the center, thereby increasing the coverage area of ​​the fixed expansion mechanism. In this process, the single telescopic distance of the hydraulic telescopic column is equal to the moving distance of the sliding rack, so as to ensure that the square is expanded proportionally; similarly, when the hydraulic telescopic column shrinks, the square formed by the first tilting rod, the second tilting rod, the third tilting rod and the fourth tilting rod are connected to shrink inward proportionally, reducing the coverage area of ​​the fixed expansion mechanism.

[0006] Furthermore, the limiting mechanism is respectively arranged on the four corners of the square formed by connecting the first tilting rod, the second tilting rod, the third tilting rod and the fourth tilting rod, the limiting mechanism includes a first push block and a second push block, the first push block is arranged on the inner side of the second push block, the first push block is in an arc shape as a whole, the distance between the two ends of the first push block and the second push block is increased, the side wall of the first push block facing the second push block is uneven, the static friction force is increased, and the upper end of the symmetrical sliding rack is connected with a shielding cover, and the shielding cover is arranged above the second push block; Further, the elastic locking type top plate assembly comprises a rotating top plate, an expansion plate and an expansion column, the rotating top plate is coaxially sleeved on the winding column, the side of the rotating top plate away from the fixed expansion mechanism is not penetrated by an expansion slot, the expansion slot is provided with four, the expansion plate is slidably arranged in the expansion slot, the expansion column is rotatably arranged on the side wall of the expansion plate facing the fixed expansion mechanism, the expansion column is movably arranged between the first push block and the second push block, and the outer side of the expansion column is sleeved with a rubber sleeve; Preferably, a linear array is provided with a snap-fitting groove on the inner side wall of the expansion slot, and triangular blocks are slidably embedded in the linear arrays on both sides of the expansion plate, and the parts of the triangular blocks protruding from the expansion plate are equilateral triangles, and a spring is connected between the triangular blocks and the expansion plate, and the triangular blocks of the array are respectively snapped with the snap-fitting grooves; a single telescopic distance of the hydraulic telescopic column and a moving distance of the sliding rack are equal to the array spacing of the triangular blocks, that is, the hydraulic telescopic column is extended once, so that the expansion plate is expanded outward by a distance of the array spacing of the triangular blocks; During specific use, when the fixed expansion mechanism is expanded, the expansion column is driven to expand outwardly through the first push block, and a large static friction force is generated between the rubber sleeve on the outside of the expansion column and the uneven first push block. In the absence of external force, the expansion column and the upper wall of the first push block will not move relative to each other. Under the pull of the expansion column, the expansion plate slides outward in the expansion slot, and the triangular block with inclined side walls slides toward the inside of the expansion plate respectively under the movement of the expansion plate and the extrusion of the side walls of the locking slot, and the spring inside it is compressed until the triangular block moves to the next locking slot and slides into it, thereby positioning the relative position of the expansion plate and the rotating top plate. Similarly, when the fixed expansion mechanism is contracted, the expansion column is pressed by the second push block, and the expansion plate slides inward in the expansion slot; in this way, the coverage area of ​​the elastic locking type top plate assembly is adjusted, which is convenient for increasing or decreasing the number of cable winding turns in actual use, thereby improving construction efficiency.

[0007] Furthermore, the follower-type circulating guide assembly includes a sliding frame, a reciprocating screw and a self-adjusting transmission mechanism, the sliding frame is connected to the telescopic end of the horizontal telescopic rod near the second inclined rod, the sliding frame is in an inverted shape, the lower part of the sliding frame is symmetrically rotated with a pulley, the pulley is slidably arranged in a sliding groove, the upper wall of the sliding frame is penetrated with a guide groove, the reciprocating screw is rotatably arranged on the inner side of the sliding frame, the air-filled extrusion type clamping assembly is meshed and sleeved on the reciprocating screw, the air-filled extrusion type clamping assembly slides in the guide groove, and the self-adjusting transmission mechanism is arranged on the side of the sliding frame away from the main power motor; Furthermore, the self-adjusting transmission mechanism comprises a fixed frame, a follower wheel, an extrusion wheel and a transmission belt, the fixed frame is arranged on a base, the fixed frame is arranged between a hydraulic telescopic column and a sliding frame, a main wheel is arranged at the end of a hydraulic telescopic column on one side of the winding column passing through, the follower wheel is arranged at one end of a reciprocating screw rod passing through the sliding frame, the center of the main wheel, the center of the follower wheel and the axis of the horizontal telescopic rod are in the same plane, the extrusion wheel is movably arranged on the inner side of the fixed frame, limiting grooves are penetrated on both sides of the fixed frame, limiting blocks are arranged on both sides of the extrusion wheel, the limiting blocks are slidably arranged in the limiting grooves, an extrusion spring is connected between the upper part of the extrusion wheel and the fixed frame, and the transmission belt is wound around the main wheel, the follower wheel and the extrusion wheel; When in use, the extension or contraction of the horizontal telescopic rod drives the sliding frame away from or close to the winding column. During adjustment, the pulley slides in the sliding groove. The movement of the sliding frame makes the air-filled extrusion clamping assembly adaptively move away from or close to the winding column, thereby ensuring the rotation space of the rotating top plate. During this process, the follower wheel follows and moves away from or close to the main wheel, thereby increasing or decreasing the transmission belt between the follower wheel and the main wheel, and the extrusion spring is compressed or extended, thereby driving the extrusion wheel at its lower part to move in the fixed frame, and the limiting block slides in the limiting groove. The elasticity of the extrusion spring keeps the transmission belt in a taut state at all times, thereby ensuring the transmission effect.

[0008] Furthermore, the air-filled extrusion clamping assembly comprises a reciprocating slider, a connecting frame, an active extrusion wheel, a follower extrusion wheel, a motor and an air pump, the reciprocating slider is meshed and sleeved on the reciprocating screw rod, the connecting frame is arranged on the upper part of the reciprocating slider, the connecting frame slides in the guide groove, the active extrusion wheel and the follower extrusion wheel are respectively rotatably arranged on the inner side of the connecting frame, the follower extrusion wheel is arranged above the active extrusion wheel, the active extrusion wheel is meshed with the follower extrusion wheel, the active extrusion wheel and the follower extrusion wheel are respectively sleeved with air bag rings, the motor and the air pump are respectively arranged on the side walls of the connecting frame, the output end of the motor is connected to the active extrusion wheel, and the output end of the air pump is connected to the air bag ring; a cleaning ring is provided on the side of the connecting frame away from the winding column, the center of the cleaning ring is on the symmetric plane of the active extrusion wheel and the follower extrusion wheel, and bristles are obliquely provided on the inner side of the cleaning ring; When winding the cable, one end of the cable is passed through the cleaning ring and between the active extrusion wheel and the follower extrusion wheel respectively, and fixed on the winding column. Then, the air pump is started to inflate the airbag ring to clamp the cable therebetween. The rubber airbag ring and the outer wall of the cable generate a large friction force, and the gas inside it provides an extrusion force to clamp the cable between the active extrusion wheel and the follower extrusion wheel. Then, the main power motor is started, and the winding column winds up the cable. In this process, the winding column drives the main rotating wheel to rotate, and the follower rotating wheel rotates under the drive of the transmission belt, thereby rotating the reciprocating screw rod. The reciprocating slider meshed with the reciprocating screw rod slides back and forth on the reciprocating screw rod due to the restriction of the connecting frame and the guide groove, thereby making the cable winding neatly arranged. The active extrusion wheel and the follower extrusion wheel rotate relatively under the drive of the cable. The extrusion and clamping force of the airbag ring keeps the cable in a taut state at all times during the winding process, and the outward-inclined bristle brush sweeps off the dust and impurities on the outer wall of the cable, so that the wound cable is clean and tidy. When the cable is to be paid out, the main power motor is started in reverse, the winding column pays out the cable, the reciprocating screw rod rotates accordingly, and the reciprocating sliding of the reciprocating slider enables the cable to be transported in an orderly manner. At the same time, the motor is started, the motor drives the active extrusion wheel to rotate, and causes the follower extrusion wheel engaged with it to rotate relatively, and the air bag ring squeezes and clamps the cable to be transported outward. There is no need for the staff to pull the cable to pay out, so that the cable is always kept taut during the pay-out process.

[0009] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The present invention provides an adjustable retractable cable reel, which is provided with a linkage expansion adjustment frame assembly, and combines and utilizes the structural characteristics of a square and an isosceles triangle, so that the fixed expansion mechanism can be adjusted to expand or contract proportionally, and the coverage area of ​​the elastic locking top plate assembly can be adjusted through the transition of the limiting mechanism, so as to facilitate the adjustment of the number of cable winding turns according to specific circumstances in actual use, thereby improving construction efficiency.

[0010] 2. The pre-action principle is adopted and a follow-up circulation guide component is set up. When the linkage expansion adjustment frame component is adjusted, it can adaptively adjust its own position. Through reciprocating motion, the cables are arranged neatly when winding and the cables are transported in an orderly manner when unwinding.

[0011] 3. By utilizing the air pressure principle and the material properties of rubber, an air-filled squeezing clamping assembly is set up. The cable is always kept in a taut state during the winding or unwinding process by squeezing and clamping with an air bag.

[0012] 4. A rotating expansion column is provided as a connection transition between the linkage expansion adjustment frame assembly and the elastic locking type top plate assembly. A rubber sleeve is provided on the outside of the expansion column. When adjusting the position of the expansion plate, the uneven upper wall of the first push block contacts the rubber sleeve, increasing the static friction therebetween. In the absence of external force, the expansion column and the upper wall of the first push block will not move relative to each other. When the expansion column rotates with the rotating top plate, the expansion column rotates and slides over the uneven upper wall of the first push block, reducing the resistance therebetween and allowing the elastic locking type top plate assembly to run smoothly.

The telescopic end of the hydraulic telescopic column 2 moves upward, driving the winding column 21 to move upward, thereby driving the fixed telescopic rod 311 to stretch upward, pushing the horizontal telescopic rod 314 and the sliding frame 317 to move upward, and at the same time pulling the telescopic ends of the first inclined rod 312 and the second inclined rod 313 to move obliquely upward, so that the telescopic ends of the horizontal telescopic rod 314 follow and extend to both sides, and the sliding frame 317 moves upward relative to the vertical plate bracket 321, so that the transition gear 323 moves upward and meshes with the fixed rack 322 to rotate, and the transition gear 323 meshes with the sliding rack 318 at the same time, driving the sliding rack 318 to move upward, thereby pulling the horizontal telescopic rod 314 and the sliding frame 317 upward. The third tilt rod 315 and the fourth tilt rod 316 are moved upward. Under the restriction of the horizontal telescopic rod 314, the third tilt rod 315 and the fourth tilt rod 316 are extended, thereby achieving the technical effect that the lower end of the fixed telescopic rod 311, the upper end of the sliding rack 318 and the telescopic end point of the horizontal telescopic rod 314 are respectively extended in four directions with the winding column 21 as the center. Then, the expansion column 44 is driven to expand outward through the first push block 331, and a large static friction force is generated between the rubber sleeve on the outside of the expansion column 44 and the uneven first push block 331. In the absence of external force, the expansion column 44 and The upper wall of the first push block 331 will not move relatively. Under the pull of the expansion column 44, the expansion plate 43 slides outward in the expansion slot 42. The triangular block 46 with an inclined side wall slides toward the inside of the expansion plate 43 under the movement of the expansion plate 43 and the squeezing of the side wall of the locking slot 45. The spring inside is compressed until the triangular block 46 moves to the next locking slot 45 and slides into it, thereby positioning the relative position of the expansion plate 43 and the rotating top plate 41. In the process of expanding the coverage range of the elastic locking type top plate assembly 4, the extension of the horizontal telescopic rod 314 pushes the sliding frame 51 away from the winding column 21. Similarly, when the coverage of the elastic locking top plate assembly 4 needs to be reduced, the hydraulic telescopic column 2 is started to shrink, and the square formed by the first tilting rod 312, the second tilting rod 313, the third tilting rod 315 and the fourth tilting rod 316 shrinks inward, so that the second push block 332 presses the expansion column 44, and the expansion plate 43 slides inward in the expansion slot 42, and at the same time pulls the sliding frame 51 close to the winding column 21; During adjustment, the pulley 53 slides in the sliding groove 12, and the movement of the sliding frame 51 makes the air-filled extrusion clamping assembly 6 adaptively move away from or close to the winding column 21, ensuring the rotation space of the rotating top plate 41. In this process, the follower wheel 552 follows and moves away from or close to the main wheel 23, causing the transmission belt 555 between the follower wheel 552 and the main wheel 23 to increase or decrease, and the extrusion spring 556 is compressed or extended, thereby driving the extrusion wheel 554 at its lower part to move in the fixed frame 551, and the limiting block 557 slides in the limiting groove 553. The elasticity of the extrusion spring 556 keeps the transmission belt 555 in a taut state at all times to ensure the transmission effect; the single telescopic distance of the hydraulic telescopic column 2 and the moving distance of the sliding rack 318 are equal to the array spacing of the triangular block 46. If you want to continue to adjust the coverage range of the expansion plate 43, you need to start the hydraulic telescopic column 2 again for adjustment.

[0024] After the adjustment is completed, when winding the cable, one end of the cable is passed through the cleaning ring 68 and between the active extrusion wheel 63 and the follower extrusion wheel 64, and fixed on the winding column 21. Then, the air pump 66 is started to inflate the airbag ring 67 to clamp the cable therebetween. The rubber airbag ring 67 generates a large friction force with the outer wall of the cable, and the gas inside it provides an extrusion force to clamp the cable between the active extrusion wheel 63 and the follower extrusion wheel 64. Then, the main power motor 22 is started, and the winding column 21 winds up the cable. During this process, the winding column 21 drives the main rotating wheel 23 to rotate. Driven by the transmission belt 555, the follower wheel 552 rotates, thereby rotating the reciprocating screw rod 52. The reciprocating slider 61 meshing with the reciprocating screw rod 52 slides back and forth on the reciprocating screw rod 52 due to the limiting effect of the connecting frame 62 and the guide groove 54, thereby making the cable winding arranged neatly. The active extrusion wheel 63 and the follower extrusion wheel 64 rotate relative to each other under the drive of the cable. The extrusion and clamping force of the airbag ring 67 keeps the cable in a taut state during the winding process. The outward-inclined bristles 69 sweep away dust and impurities on the outer wall of the cable, making the wound cable clean and tidy.

[0025] When the cable is to be paid out, the main power motor 22 is started in reverse, the winding column 21 pays out the cable, the reciprocating screw rod 52 rotates accordingly, and the reciprocating sliding of the reciprocating slider 61 enables the cable to be transported in an orderly manner. At the same time, the motor 65 is started, and the motor 65 drives the active extrusion wheel 63 to rotate, and causes the follower extrusion wheel 64 meshing with it to rotate relatively, and the airbag ring 67 squeezes and clamps the cable to be transported outward. There is no need for the staff to pull the cable to pay out, so that the cable is always kept taut during the pay-out process.

[0026] During the rotation of the rotating top plate 41, the triangular block 46 is engaged in the engaging groove 45 under the action of the spring. The centrifugal force generated by the rotation of the rotating top plate 41 is not sufficient to enable the triangular block 46 to overcome the elastic force of the spring and slide into the expansion plate 43. The triangular blocks 46 of the linear array locate the relative positions of the expansion plate 43 and the rotating top plate 41. The rotation trajectory of the expansion column 44 is between the first push block 331 and the second push block 332. During this period, the expansion column 44 rotates and slides over the uneven upper wall of the first push block 331 to reduce the resistance between the two.

[0027] During the process of cable retraction and release, the machine can be stopped at any time to adjust the coverage of the elastic locking top plate assembly 4 to adapt to the actual use length of the cable, avoid the situation of power cable reeling in sections, and improve construction efficiency.

[0028] It is worth noting that the tooth spacing setting of the fixed rack 322, the transition gear 323 and the sliding rack 318 and the spacing setting of the triangular block 46 can be calculated through existing technology. In addition, the use of the hydraulic telescopic column 2, the reciprocating screw 52, ​​the air pump 66 and the motor 65 are all existing technologies and will not be repeated here.

[0029] The above is the overall workflow of the present invention, and you can repeat this step next time you use it.
