Description

Technical Field

[0001] This utility model relates to the field of cable unwinding technology, and in particular to a cable unwinding device for power engineering construction. Background Technology

[0002] In the early stages of power engineering construction, cable unwinding mainly relied on manual operation, which was inefficient and prone to errors. As the scale of power engineering construction continued to expand, the demand for cable unwinding equipment also increased. With the development of technology, the introduction of mechanical structures and electronic technology has made it possible to develop cable rapid unwinding equipment.

[0003] A Chinese patent discloses a portable cable unwinding device (authorization announcement number CN216785355U). It works by first pulling a telescopic component outward to separate it from a first locking block. Under the elastic force of a first spring, the connecting horizontal plate and the second locking block move upward synchronously. During this movement, the second locking block engages with a locking hole at an appropriate position, thus fixing the position of the unwinding wheel and preventing it from rotating. This prevents accidental cable winding due to unexpected rotation of the unwinding wheel. However, the specification reveals that both sets of connecting shafts have fixed vertical plates rotatably sleeved on their outer walls via bearings. Therefore, when the unwinding wheel... When disassembly, replacement, or repair is required, such as when a cable on an unwinding reel needs to be replaced with a new unwinding reel containing the cable after the cable has been unwound, workers need to use external tools to remove the connecting shaft from the fixed vertical plate, replace the new unwinding reel with the cable, and then use external tools to install the connecting shaft back onto the fixed vertical plate to complete the unwinding reel replacement. This increases the time required for disassembly and assembly of the unwinding reel, reduces the efficiency of unwinding reel replacement, and makes the disassembly and assembly of the unwinding reel time time-consuming and labor-intensive, increasing the overall unwinding time of the cable, reducing the unwinding efficiency of the cable, extending the unwinding cycle of the cable, and affecting the construction cycle of power engineering projects. Utility Model Content

The drive mechanism includes a first servo motor, a gear, a first rack, and a second rack. A groove is formed on the top of the base, which is arranged along the length of the guide rail. Guide grooves are formed on both sides of the groove, which extend along the length of the groove. The first rack and the second rack are slidably disposed within their respective guide grooves. One end of the first rack and the second rack are fixedly connected to the first slide block and the second slide block, respectively. The first servo motor is disposed within the groove. The gear is fixedly sleeved on the output shaft of the first servo motor. The other ends of the first rack and the second rack mesh with each other on both sides of the gear.

[0007] Furthermore, the two guide rails are disposed opposite to each other on the top of the base, and the sliders are provided at both ends of the first and second slides in the width direction. The sliders are slidably connected in the corresponding guide rails, and the first and second slides are slidably connected between the two guide rails.

[0008] Furthermore, both the first rack and the second rack have guide blocks on their sides facing away from the gear, and the guide blocks are slidably connected in the corresponding guide grooves.

[0009] Furthermore, a first mounting bracket is provided on the top of the first slide, and the first mounting plate is rotatably mounted on the first mounting bracket; a second mounting bracket is provided on the top of the second slide, and the second mounting plate is rotatably mounted on the second mounting bracket.

[0010] Furthermore, the first mounting bracket is equipped with a second servo motor, and the output shaft of the second servo motor is fixedly connected to the first mounting plate.

[0011] Furthermore, self-locking casters are provided at the four corners of the bottom of the base.

[0012] Furthermore, the front and rear side walls of the base are each provided with two support mechanisms. The support mechanism includes a push rod, an adjusting rod, and an insert rod.

The fixed end of the push rod is hinged to the base, and the telescopic end of the push rod is hinged to the adjusting rod.

[0013] The beneficial effects of this utility model are:

[0014] This application discloses a cable unwinding device for power engineering construction, comprising a base, a guide rail, a drive mechanism, and an installation mechanism consisting of a first clamping mechanism and a second clamping mechanism mounted on the base. The drive mechanism drives the first and second clamping mechanisms to move closer or further apart, clamping or releasing the unwinding wheel, thereby enabling the installation or removal of the unwinding wheel for unwinding cables. The first clamping mechanism includes a first mounting plate mounted on a first slide, with a first unwinding wheel sleeve on the first mounting plate. The second clamping mechanism includes a second mounting plate mounted on a second slide, with a second unwinding wheel sleeve on the second mounting plate. When installing the unwinding wheel, the two ends of the center positioning hole of the unwinding wheel are fitted onto the first and second unwinding wheel sleeves. The first and second slides are slidably connected to the guide rail via a slider. The drive mechanism includes a first servo motor, a gear, a first rack, and a second rack. One end of the first and second racks are respectively fixedly connected to the first and second slides. A groove is formed on the top of the base. The servo motor is installed in the groove, and the gear is fixedly installed on the output shaft of the first servo motor. Guide grooves are opened on both sides of the groove. The back ends of the first rack and the second rack are slidably connected in the corresponding guide grooves on both sides of the groove. The tooth surfaces of the first rack and the second rack mesh with each other on both sides of the gear. When the first servo motor works, the output shaft of the first servo motor rotates, which drives the gear to rotate, which drives the first rack and the second rack to move synchronously in opposite directions, which drives the first slide and the second slide to move in opposite directions, which drives the first mounting plate and the second mounting plate to move closer to each other or further away from each other, thus clamping or releasing the unwinding wheel, realizing the installation or removal of the unwinding wheel. When replacing the unwinding wheel, the output shaft of the first servo motor rotates in the reverse direction, driving the gear to rotate in the reverse direction. This causes the meshing first and second racks to move away synchronously in the opposite direction, driving the first and second slides to move away from each other, and the first and second mounting plates to move away from each other. The unwinding wheel disengages from the first and second unwinding wheel sleeves. The first servo motor stops working, and the unwinding wheel is removed and lifted away, completing the disassembly and removal of the old unwinding wheel. The new unwinding wheel is then brought in, and its center positioning hole is aligned with the first and second unwinding wheel sleeves. The output shaft of the first servo motor rotates in the forward direction, driving the gear to rotate in the forward direction. This causes the meshing first and second racks to move closer together synchronously, driving the first and second slides to move closer together, and the first and second mounting plates to move closer together. The first and second unwinding wheel sleeves are inserted into the center positioning hole of the unwinding wheel until there is a rotational clearance between the two sides of the unwinding wheel and the first and second mounting plates. The first servo motor stops working, completing the clamping and installation of the new unwinding wheel.In summary, when using the cable unwinding equipment for power engineering construction of this application to replace the unwinding reel, the first and second mounting reels do not need to be removed with external tools during disassembly, and the removed first and second mounting reels do not need to be installed with external tools during installation. The unwinding reel installation and disassembly operations are simple and quick, saving time and effort, improving the efficiency of unwinding reel replacement, improving the overall unwinding efficiency of the cable, shortening the cable unwinding cycle, and shortening the construction cycle of power engineering projects.

One end of each rack is fixedly connected to a first slide block 41 and a second slide block 46, respectively. The first servo motor 51 is disposed within the groove 11. The gear 54 is fixedly mounted on the output shaft of the first servo motor 51. The other ends of the first rack 53 and the second rack 52 mesh with opposite sides of the gear 54. A battery is provided in the base 1. The first servo motor 51 is electrically connected to the battery, which provides power to the first servo motor 51. The first servo motor 51, the double-throw switch, and the battery are connected via wires. A mounting bracket is welded inside the groove 11, and the first servo motor 51 can be mounted inside the groove 11 through the mounting bracket. The first servo motor 51 is located at the center of the bottom of the groove. A guide groove 12 is opened on each of the two side walls of the groove 11, and the guide groove 12 on one side wall of the groove 11 and the guide groove 12 on the other side wall are arranged opposite to each other.

[0024] The cable unwinding equipment for power engineering construction based on the above structure includes a base 1, on which a guide rail 3, a drive mechanism 5, and an installation mechanism 4 consisting of a first clamping mechanism and a second clamping mechanism are provided. The drive mechanism 5 drives the first clamping mechanism and the second clamping mechanism to move closer or further away from each other, thereby clamping or releasing the unwinding wheel 9, realizing the installation or disassembly of the unwinding wheel 9, and is used for unwinding the cable from the unwinding wheel 6.

When installing the unwinding wheel 9, both ends of the center positioning hole of the unwinding wheel 9 are fitted onto the first unwinding wheel sleeve 45 and the second unwinding wheel sleeve 47. The first slide 41 and the second slide 46 are slidably connected to the guide rail 3 via a slider 7. The driving mechanism includes a first servo motor 51, a gear 54, a first rack 53 and a second rack 52.

Guide grooves 12 are opened on both sides of the groove 11. The back ends of the first rack 53 and the second rack 52 are slidably connected in the corresponding guide grooves 12 on both sides of the groove 11. The tooth surfaces of the first rack 53 and the second rack 52 are meshed on both sides of the gear 54. When the first servo motor 51 works, the output shaft of the first servo motor 51 rotates and drives the gear 54 to rotate, which drives the first rack 53 and the second rack 52 to move synchronously in opposite directions, which drives the first slide 41 and the second slide 46 to move in opposite directions, which drives the first mounting plate 44 and the second mounting plate 48 to move closer to each other or further away from each other, thereby clamping or releasing the unwinding wheel 9 and realizing the installation or removal of the unwinding wheel 9.When replacing the unwinding reel 9, turn the switch to the reverse position. The output shaft of the first servo motor 51 rotates in the reverse direction, driving the gear 54 to rotate in the reverse direction. This causes the meshing first rack 53 and second rack 52 to move away in the opposite direction, driving the first slide 41 and second slide 46 to move away from each other, and driving the first mounting plate 44 and second mounting plate 48 to move away from each other. The unwinding reel 9 disengages from the first unwinding reel sleeve 45 and the second unwinding reel sleeve 47. Turn the switch to the interrupt position, and the first servo motor 51 stops working. Remove and lift the unwinding reel 9 to complete the disassembly and removal of the old unwinding reel 9. Lift or lift the new unwinding reel 9, and align the center positioning hole of the unwinding reel 9 with the first unwinding reel sleeve 47. 5. Align the second unwinding wheel sleeve 47, turn the switch to the forward rotation position, the output shaft of the first servo motor 51 rotates in the forward direction, driving the gear 54 to rotate in the forward direction, driving the meshing first rack 53 and second rack 52 to move closer to each other synchronously, driving the first slide 41 and second slide 46 to move closer to each other, driving the first mounting plate 44 and second mounting plate 48 to move closer to each other, the first unwinding wheel sleeve 45 and the second unwinding wheel sleeve 47 are inserted into the center positioning hole of the unwinding wheel 9 until there is the required rotation gap between the two sides of the unwinding wheel 9 and the first mounting plate 44 and the second mounting plate 48, turn the switch to the interrupt position, the first servo motor 51 stops working, and the clamping and installation of the new unwinding wheel 9 is completed.

[0025] As one possible implementation method, such as Figure 1 , Figure 2 As shown, the two guide rails 3 are disposed opposite to each other on the top of the base 1. The first slide 41 and the second slide 46 are provided with sliders 7 at both ends in the width direction. The sliders 7 are slidably connected in the corresponding guide rails 3. The first slide 41 and the second slide 46 are slidably connected between the two guide rails 3.

[0026] Two guide rails 3 are welded to the top of the base 1. A groove 11 is located between the two guide rails 3. A slider 7 is welded or integrally formed on the two end arms of the first slide block 41 and the second slide block 46 in the width direction, for sliding the first slide block 41 and the second slide block 46 between the two guide rails 3. The width direction of the first slide block 41 and the width direction of the second slide block 46 are the same as the short side direction of the first slide block 41 and the short side direction of the second slide block 46.

[0027] As one possible implementation method, such as Figure 1 , Figure 2 As shown, guide blocks 8 are provided on the sides of the first rack 53 and the second rack 52 facing away from the gear 54, and the guide blocks 8 are slidably connected in the corresponding guide grooves 12.

[0028] The guide block 8 is welded or integrally formed on the first rack 53 and the second rack 52, and is used to slide the first rack 53 and the second rack 52 into the corresponding side wall guide grooves 12 of the groove 11.

A second mounting bracket 49 is provided on the top of the second slide 46, and the second mounting plate 48 is rotatably mounted on the second mounting bracket 49.

[0030] The first mounting bracket 4 is screwed or welded to the top of the first slide 41, and the second mounting bracket 49 is screwed or welded to the top of the second slide 46. Through holes are drilled at the top of the first mounting bracket 43 and the top of the second mounting bracket 49. A shaft is integrally formed on the side of the first mounting plate 44 facing away from the first unwinding wheel sleeve rod, and a shaft is integrally formed on the side of the second mounting plate 48 facing away from the second unwinding wheel sleeve rod 47, and a shaft is integrally formed on the side of the second mounting plate 48 facing away from the second unwinding wheel sleeve rod 47, and a shaft is rotatably inserted into the through hole of the first mounting bracket 4. The outer diameter of the first mounting plate 44 is larger than the inner diameter of the through hole of the first mounting bracket 4. The shaft of the second mounting plate 48 is rotatably inserted into the through hole of the second mounting bracket 49. The outer diameter of the second mounting plate 48 is larger than the inner diameter of the through hole of the second mounting bracket 49. The first mounting plate 44 and the second mounting plate 48 are arranged opposite to each other. The first mounting bracket 43 and the second mounting bracket 49 are used to mount the first mounting plate 44 and the second mounting plate 48.

[0031] As one possible implementation method, such as Figure 1 , Figure 2 As shown, the first mounting bracket 43 is equipped with a second servo motor 42, and the output shaft of the second servo motor 42 is fixedly connected to the first mounting plate 44.

[0032] The output shaft of the second servo motor 42 is welded to or splined to the shaft of the first mounting plate 44. The output shaft of the second servo motor 42 is coaxial with the first mounting plate 44. During unwinding, the second servo motor 42 operates, and its output shaft rotates, causing the first mounting plate 44 to rotate, which in turn rotates the second unwinding wheel sleeve 47, ultimately rotating the unwinding wheel 9 to complete the unwinding operation, improving unwinding efficiency and reducing labor intensity. The second servo motor 42 can be powered by a battery or an external power source. The second servo motor 42 can be a servo motor of model ACSM110-G04030LZ.

[0033] As one possible implementation method, such as Figure 1 As shown, self-locking casters 2 are provided at the four corners of the bottom of the base 1.

[0034] The self-locking casters 2 facilitate the flexible movement of the cable unwinding equipment for power engineering construction to the unwinding area, and then lock it to stop moving.

[0035] As one possible implementation method, such as Figure 1 , Figure 3 As shown, the front and rear side walls of the base 1 are each provided with two support mechanisms 6. Each support mechanism 6 includes a push rod 61, an adjusting rod 62, and an insert rod 63. One end of the adjusting rod 62 is hinged to the base 1. A disc 64 is fixed to the top end of the insert rod 63. The other end of the adjusting rod 62 passes vertically through the insert rod 63. The fixed end of the push rod 61 is hinged to the base 1, and the telescopic end of the push rod 61 is hinged to the adjusting rod 62.

[0036] The adjusting rod 62 is hinged to one end of the base 1, and a vertical through hole is drilled at the other end. The insertion rod 63 is slidably inserted into the through hole, and the bottom of the insertion rod 63 is cone-shaped. When the cable unwinding equipment for power engineering construction is moved to the unwinding area, the self-locking caster 2 is locked, and the adjusting rod 62 is pushed outward away from the base 1. The insertion rod 63 is then inserted into the adjusting rod 62, and its bottom is fixed into the soil of the unwinding area. The support mechanism 6 increases the stability of the base 1 during the unwinding process, reducing the probability of swaying and tipping. The four support mechanisms 6 are foldable and do not occupy extra space after use. Furthermore, the push rod 61 is an electric push rod, electrically connected to the battery. The battery powers the electric push rod. After the self-locking caster 2 is locked, the electric push rod operates, extending its push rod to push the adjusting rod 62 outward away from the base 1. This is convenient to operate and simultaneously supports the adjusting rod 62. The hinged connection uses an existing hinge seat, pin, and pin hole structure. The hinge seat is welded or screwed onto the base 1 or the adjusting rod 62. The outer diameter of the disc 64 is larger than the inner diameter of the through hole of the adjusting rod 62 to prevent the upper end of the insertion rod 63 from entering the through hole and being difficult to pull out when it is inserted into the soil.

[0037] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
