Description

Technical Field

[0001] This utility model relates to the field of cable reel laying technology, specifically to an automatic cable reel laying device for construction. Background Technology

[0002] Existing cable reel laying equipment is commonly used in construction and power installation projects. It typically employs a dual-frame structure, with each frame equipped with a liftable platform to accommodate different laying height requirements. Two bearings are arranged side-by-side at the top of the lifting platform, the distance between them forming a space for the cable reel. The cable reel is horizontally mounted above the bearings on both frames and passes through the central hole of the cable reel. A drive device rotates the cable reel to automatically lay the cable. Support rods are evenly distributed around both sides of the cable reel to enhance its structural strength. While existing equipment meets basic construction needs to a certain extent, the fixing method between the cable reel and the cable reel has shortcomings, leading to relative sliding or axial displacement during rotation. Therefore, an improved solution is urgently needed to reliably fix the cable reel and the cable reel to address the technical problem of insufficient connection stability in existing technologies. Utility Model Content

[0005] The fixed ring is coaxially fixedly sleeved on the shaft tube;

[0006] The sliding ring is mounted on the shaft tube, and the inner ring is coaxially connected to the connecting tube. The connecting tube is detachably sleeved on the shaft tube through a connector.

[0007] Both the moving ring and the fixed ring have multiple U-shaped rods arranged circumferentially. The two ends of the U-shaped rods pass through any support rod, fixed ring or moving ring circumference and are threaded. Each threaded segment is screwed with the first nut.

[0009] A preferred embodiment is that each rack also includes a base, a support plate, and two vertically mounted slide bars fixed on the base;

[0010] The two ends of the bearing plate are fixedly connected to two sliding rods respectively, the top seat of the jack is fixedly connected to the bearing plate, and the telescopic rod is fixedly connected to the lifting plate.

[0011] Sleeves are fixedly installed at both ends of the lifting plate, and the sleeves are fitted onto the sliding rod, with each sleeve corresponding to the other.

[0012] A preferred embodiment is that each rack also includes a rectangular plate;

[0013] The bottom wall of the rectangular plate is fixedly connected to the top of the two sliding rods, and reinforcing rods are fixedly installed at the four corners at an angle. The end of each reinforcing rod away from the rectangular plate is fixedly connected to the base.

[0014] A preferred embodiment is that the drive components include a chain, a driven sprocket, and a motor;

[0015] The motor's base is fixedly connected to any frame, and the output shaft is fixedly fitted with a drive sprocket, the driven sprocket is fixedly fitted on the shaft tube, and the chain is fitted on the drive sprocket and the driven sprocket.

[0016] A preferred embodiment is that the automatic cable reel laying device for construction also includes a drive component for rotating the shaft tube, and the drive component further includes a mounting plate, a pressing rod, a U-shaped plate and a compression spring;

[0017] One end of the mounting plate is fixedly connected to the frame on which the motor is installed, and the other end is fixedly fitted with a horizontal tube with a strip-shaped groove along its axial direction.

[0018] One end of the pressing rod is fixed to the sealing end of the U-shaped plate, and the other end is inserted into the horizontal tube. One end of the pressing rod is slidably set in the horizontal tube, and a guide rod is fixedly set. The guide rod is inserted into the strip groove.

[0019] The compression spring is sleeved on the pressing rod, and its two ends are fixedly connected to the sealing end of the U-shaped plate and the mounting plate, respectively.

[0020] A roller is mounted on the open end of the U-shaped plate, and the roller abuts against the chain.

The sliding ring moves axially along the shaft tube, bringing it and the fixed ring close to the support rods on both sides of the cable reel. The connecting tube of the inner tube of the sliding ring is fixed to the shaft tube through the connector, forming a double-ring clamping structure. The two ends of the U-shaped rod are passed through the gap of the cable reel support rod, the fixed ring, or the sliding ring in sequence. The first nut is tightened on the threaded section of the U-shaped rod, clamping the support rod between the fixed ring and the sliding ring. The synchronous tightening of the U-shaped rod at multiple points forms a radial constraint force, eliminating the rotational sliding gap between the cable reel and the shaft tube. The bearing height is adjusted by the lifting plate adjustment mechanism to keep the shaft tube horizontal. The shaft tube is started to rotate. The fixed ring and the sliding ring drive the cable reel to rotate synchronously through the rigid connection of the U-shaped rod. The cross constraint of the U-shaped rod and the support rod effectively resists the rotational tangential force. The preload of the nut prevents axial displacement. The cable is stably unfolded from the cable reel under the action of traction force, and the support rod maintains the structural stability of the reel. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0035] like Figures 1-5 As shown, this embodiment provides an automatic cable reel laying device for construction, including two frames 10, as follows: Figure 3 As shown, each frame 10 is equipped with a lifting plate 11. Each frame 10 includes a jack 100, the top seat of which is fixedly connected to the frame 10, and the telescopic rod of the jack 100 is fixedly connected to the lifting plate 11. Two bearings 12 are mounted side-by-side at the top of the lifting plate 11, the distance between which forms an erection space 13. A shaft tube 20 is erected on both erection spaces 13, passing through the center hole of the cable reel 1, and connected to a drive component 21 for rotating the shaft tube. Figure 5 As shown, the cable reel 1 includes a reel body 3 for winding cables and two retaining rings 4. Multiple support rods 2 are fixedly mounted on the outer circumference of each retaining ring 4, and the ends of the support rods 2 furthest from the retaining rings 4 are fixedly connected to the reel body 3. Figure 3As shown, each frame 10 also includes a base 14, a support plate 15, and two vertically arranged sliding rods 16 fixed on the base 14. The two ends of the support plate 15 are fixedly connected to the two sliding rods 16, respectively. The top seat of the jack 100 is fixedly connected to the support plate 15, and the telescopic rod of the jack 100 is fixedly connected to the lifting plate 11. Sleeves 17 are fixedly installed at both ends of the lifting plate 11, and the sleeves 17 slide on the sliding rods 16, with each sleeve corresponding to the other. The sleeves guide the lifting plate. Each frame 10 also includes a rectangular plate 18. The bottom wall of the rectangular plate 18 is fixedly connected to the top ends of the two sliding rods 16, and reinforcing rods 19 are inclinedly installed at the four corners. The end of each reinforcing rod 19 away from the rectangular plate 18 is fixedly connected to the base 14. The four reinforcing rods 19 increase the stability of the overall structure.

[0036] The automatic cable reel laying device for construction also includes a fixed ring 30 and a shifting ring 40. The fixed ring 30 is coaxially fixed on the shaft tube 20. The shifting ring 40 is slidably mounted on the shaft tube 20, and the inner ring of the shifting ring 40 is coaxially connected to the connecting tube 41. The connecting tube 41 is detachably mounted on the shaft tube 20 via a connector 42. Both the shifting ring 40 and the fixed ring 30 have multiple U-shaped rods 50 arranged circumferentially. The two ends of each U-shaped rod 50 pass through any support rod 2, the fixed ring 30, or the shifting ring 40, and a threaded section 51 is opened on the circumference. Each threaded section 51 is screwed with a first nut 52. The connector 42 includes a second bolt 420 and a second nut 421. The second bolt 420 passes through one side wall of the connecting tube 41, one side wall of the shaft tube 20, the other side wall of the shaft tube 20, and the other side wall of the connecting tube 41 in sequence and is screwed with the second nut 421.

[0037] The shaft tube 20 is passed through the center hole of the cable reel 1, placing the cable reel 1 between the two frames 10. The sliding ring 40 moves axially along the shaft tube 20, bringing it and the fixed ring 30 close to the support rods 2 on both sides of the cable reel 1. The connecting tube 41 of the inner tube of the sliding ring 40 is fixed to the shaft tube 20 through the connector 42, forming a double-ring clamping structure. The two ends of the U-shaped rod 50 are passed through the gap between the support rods 2 of the cable reel 1, the fixed ring 30, or the sliding ring 40 in sequence. The first nut 52 is tightened on the threaded section 51 of the U-shaped rod 50, so that the support rod 2 is clamped between the fixed ring 30 and the sliding ring 40. The synchronous tightening of the U-shaped rod 50 at the point forms a radial constraint force, eliminating the rotational sliding gap between the cable reel 1 and the shaft tube 20. The height of the bearing 12 is adjusted by the lifting plate 11 adjustment mechanism to keep the shaft tube 20 in a horizontal state. The shaft tube 20 is started to rotate. The fixed ring 30 and the moving ring 40 drive the cable reel 1 to rotate synchronously through the rigid connection of the U-shaped rod 50. The cross constraint between the U-shaped rod 50 and the support rod 2 effectively resists the rotational tangential force. The pre-tightening force of the first nut prevents axial displacement. The cable is stably unfolded from the cable reel 1 under the action of traction force. The support rod 2 maintains the structural stability of the reel body 3.

[0038] like Figure 3 , Figure 4 As shown, the drive component 21 includes a chain 210, a driven sprocket 211, and a motor 212. The base of the motor 212 is fixedly connected to any frame 10, and the output shaft of the motor 212 is fixedly fitted with a drive sprocket 213. The driven sprocket 211 is fixedly fitted on the shaft tube 20, and the chain 210 is fitted on the drive sprocket 213 and the driven sprocket 211. The drive component 21 also includes a mounting plate 214, a pressing rod 215, a U-shaped plate 216, and a compression spring 217. One end of the mounting plate 214 is fixedly connected to the frame 10 on which the motor 212 is mounted, and the other end of the mounting plate 214 is fixedly fitted with a horizontal tube 218. The horizontal tube 218 has a strip-shaped groove 2180 formed along its axial direction on its circumferential wall. One end of the pressing rod 215 is fixedly installed at the sealing end of the U-shaped plate 216, and the other end of the pressing rod 215 passes through the horizontal tube 218. One end of the pressing rod 215 is slidably installed in the horizontal tube 218, and the other end of the pressing rod 215 is fixedly installed with a guide rod 2151, which is inserted into the strip groove 2180. A compression spring 217 is sleeved on the pressing rod 215, and both ends are fixedly connected to the sealing end of the U-shaped plate 216 and the mounting plate 214, respectively. A roller 219 is rotatably installed at the open end of the U-shaped plate 216, and the roller 219 abuts against the chain 210.

[0039] When motor 212 starts, its output shaft drives drive sprocket 213 to rotate. Drive sprocket 213 transmits power to driven sprocket 211 at the end of shaft tube 20 via chain 210, causing shaft tube 20 and cable reel 1 to rotate synchronously. As shaft tube 20 rotates, cable reel 1 rotates stably under the clamping of fixed ring 30 and shifting ring 40, and the cable is released at a uniform speed under traction. U-shaped plate 216 moves with pressing rod 215, driving roller 219 to continuously press down on chain 210, maintaining constant tension on chain 210. If chain 210 experiences excessive tension due to thermal expansion or external pressure, roller 219 retracts under reaction force, compression spring 217 contracts, and pressing rod 215 slides in the opposite direction along horizontal tube 218, preventing chain 210 from becoming overly taut. The guide rod 2151 on the pressing rod 215 is embedded in the strip groove 2180 of the horizontal tube 218, restricting the pressing rod 215 to move only axially and preventing the roller 219 from swaying and causing the chain 210 to derail. Each slide rod 16 has a through hole 161 along its axial direction, and a pin (not shown) is inserted into any of the through holes 161.
