Description

Technical Field

[0001] The present invention relates to the technical field of power equipment, and particularly to a cable pay-off rack. Background Art

[0002] A cable pay-off rack is an important device for supporting, protecting, and organizing cables, and is widely used in construction, power transmission and distribution, communication, and other fields. The cable reel is sleeved on the support crossbar, and the operator pulls the cable on the cable reel. The cable reel drives the support crossbar to rotate, thereby realizing the corresponding pay-off process. However, the diameter of the existing cable reel is often relatively large, and the diameter and weight of the cable are also relatively large. During the pay-off process, the pay-off personnel pull the cable to drive the cable reel to rotate, thereby realizing the pay-off process. However, during the rotation of the relatively large cable reel, a large moment of inertia is generated, and it is usually impossible to immediately stop the pay-off. Often, the pay-off length is longer than the designed length, resulting in waste of the cable, and it is more difficult to rewind and store it again. There is a problem that the cable pay-off rack lacks a deceleration and stop mechanism, which affects the work efficiency. Summary of the Invention

[0032] Embodiment 1

[0033] Referring to Figures 1-5 , a schematic view of the overall structure of a cable pay-off rack is provided. A cable pay-off rack includes a support assembly 100, which includes a first support member 101 and a second support member 102 movably connected to the first support member 101. The distance between the first support member 101 and the second support member 102 can be adjusted. The two ends of the support crossbar of the cable reel are arranged on the first support member 101 and the second support member 102. After adjusting the distance between the first support member 101 and the second support member 102, the first support member 101 and the second support member 102 can be fixedly connected with bolts, and then the support crossbar and the cable reel are lifted off the ground through the first support member 101 and the second support member 102, facilitating the pulling of the cable for pay-off.

[0034] Further, the deceleration assembly 200 includes a fixing member 201 disposed on the first support member 101 and the second support member 102, a rotating member 202 movably connected to the fixing member 201, a first deceleration member 203 movably connected to the rotating member 202, a second deceleration member 204 movably connected to the rotating member 202, and a sliding member 205 movably connected to the rotating member 202. The fixing member 201 is used to fix the support crossbar of the cable reel, so that the support crossbar and the cable reel can rotate within the fixing member 201. By pushing the sliding member 205, the sliding member 205 presses against and drives the rotating member 202 to rotate. The rotation of the rotating member 202 first drives the first deceleration member 203 to decelerate the support crossbar and the cable reel. When the rotating member 202 continues to rotate through the sliding member 205, the rotating member 202 drives the second deceleration member 204 to perform secondary deceleration and stop on the support crossbar and the cable reel, so that the support crossbar and the cable reel can immediately stop paying out the cable.

[0035] Operation process: The two ends of the support crossbar of the cable reel are disposed on the first support member 101 and the second support member 102 through the provided first support member 101 and second support member 102. Then, the support crossbar and the cable reel are lifted off the ground through the first support member 101 and the second support member 102, facilitating the pulling of the cable for cable pay-out. The fixing member 201 on the first support member 101 and the second support member 102 is used to fix the support crossbar of the cable reel, so that the support crossbar and the cable reel can rotate within the fixing member 201. Through the fixing member 201, it is possible to prevent the support crossbar and the cable reel from sliding off during rotation, thus avoiding potential safety hazards. By pushing the sliding member 205, the sliding member 205 presses against and drives the rotating member 202 to rotate. The rotation of the rotating member 202 first drives the first deceleration member 203 to decelerate the support crossbar and the cable reel. When the rotating member 202 continues to rotate through the sliding member 205, the rotating member 202 drives the second deceleration member 204 to perform secondary deceleration and stop on the support crossbar and the cable reel, so that the support crossbar and the cable reel can immediately stop paying out the cable, solving the problem that the cable pay-out rack lacks a deceleration and stop mechanism, which affects the working efficiency.

[0036] Embodiment 2

[0037] Refer to Figures 1-5, what is different about this embodiment from the first embodiment is that the first support member 101 includes a first placement base plate 101a, a first connection plate 101b, a first support column 101c, a first hydraulic cylinder 101d, and a first sliding groove block 101e. A first inclined sliding surface 101a-1 is provided at the front end of the first placement base plate 101a.

The first hydraulic cylinder 101d is fixedly connected to the first placement base plate 101a. The first sliding groove block 101e is slidably connected to the first support column 101c. A first placement groove 101e-1 is provided on the first sliding groove block 101e, and the first placement groove 101e-1 is convenient for placing the support cross bar of the cable reel.

[0038] Specifically, the second support member 102 includes a second placement base plate 102a, a second support column 102b, a second hydraulic cylinder 102c, and a second sliding groove block 102d. A second inclined sliding surface 102a-1 is provided at the front end of the second placement base plate 102a, and a connection groove 102a-2 is provided on the second placement base plate 102a. The connection groove 102a-2 cooperates with the first connection plate 101b, and the first connection plate 101b is arranged in the connection groove 102a-2. The first support member 101 and the second support member 102 are fixedly connected by bolts on the connection groove 102a-2. The second support column 102b is fixedly connected to the second placement base plate 102a. The second hydraulic cylinder 102c is fixedly connected to the second placement base plate 102a. The second sliding groove block 102d is slidably connected to the second support column 102b. A second placement groove 102d-1 is provided on the second sliding groove block 102d. When the first hydraulic cylinder 101d and the second hydraulic cylinder 102c are activated, they drive the first sliding groove block 101e and the second sliding groove block 102d to slide upward, thereby driving the support cross bar of the cable reel and the cable reel in the first placement groove 101e-1 and the second placement groove 102d-1 to slide upward. After sliding up to a certain height, it is convenient to pull the cable for cable laying.

[0039] Further, the fixing member 201 includes a fixing arc plate 201a, a first rotating bead 201b, a rotating arc plate 201c and a second rotating bead 201d. The fixing arc plate 201a is disposed on the lower side of the first placement groove 101e-1 and fixedly connected to the first sliding groove block 101e. A plurality of mounting grooves 201a-1 are provided on the fixing arc plate 201a. The first rotating bead 201b is movably connected to the fixing arc plate 201a. One end of the rotating arc plate 201c is rotatably connected to the fixing arc plate 201a, and the other end of the rotating arc plate 201c is bolted to the fixing arc plate 201a. The support cross bar of the cable reel is fixed between the fixing arc plate 201a and the rotating arc plate 201c by bolts. The second rotating bead 201d is movably connected to the rotating arc plate 201c. The first rotating bead 201b and the second rotating bead 201d are abutted against the support cross bar of the cable reel, facilitating the rotation of the support cross bar of the cable reel through the first rotating bead 201b and the second rotating bead 201d.

[0040] The remaining structures are the same as those in Embodiment 1.

[0041] Operation process: Through the cooperation of the connection groove 102a-2 of the second placement bottom plate 102a and the first connecting plate 101b, the first support member 101 and the second support member 102 are fixedly connected, enhancing the stability. Initially, the first sliding groove block 101e and the second sliding groove block 102d are at a low position, facilitating manual pushing of the cable reel and the support cross bar of the cable reel to be disposed in the first placement groove 101e-1 and the second placement groove 102d-1. By starting the first hydraulic cylinder 101d and the second hydraulic cylinder 102c, the support cross bar of the cable reel and the cable reel in the first placement groove 101e-1 and the second placement groove 102d-1 are driven to slide upward along the directions of the first support column 101c and the second support column 102b away from the ground, facilitating the pulling of the cable to rotate and unwind the cable reel and the support cross bar of the cable reel. The support cross bar of the cable reel is fixed by the fixing arc plate 201a and the rotating arc plate 201c. The first rotating bead 201b and the second rotating bead 201d are abutted against the support cross bar of the cable reel, facilitating the rotation of the support cross bar of the cable reel through the first rotating bead 201b and the second rotating bead 201d, solving the problems that the cable reel and the support cross bar of the cable reel are inconvenient to lift and install on the cable laying reel due to their heavy weights, and the support cross bar of the cable reel lacks fixation, posing a safety hazard.

[0042] Embodiment 3

[0043] Refer to Figures 1-10, what is different about this embodiment from the above embodiments is that the rotating member 202 includes a rotating disk 202a, a rotating cylinder 202b, an abutting cylinder 202c, and an abutting block 202d. The rotating disk 202a is arranged in the installation groove 201a-1 and is rotatably connected to the first sliding groove block 101e. A first sliding groove 202a-1 is provided on the rotating disk 202a. The first sliding groove 202a-1 is divided into a contraction section 202a-1a and a rotating section 202a-1b. The rotating cylinder 202b is fixedly connected to the rotating disk 202a. A second sliding groove 202b-1 is provided on the rotating cylinder 202b. The abutting cylinder 202c is fixedly connected to the rotating disk 202a. The abutting block 202d is fixedly connected to the abutting cylinder 202c. The rotating disk 202a and the rotating cylinder 202b can rotate.

[0044] Specifically, the rotating member 202 further includes a sliding column 202e, a first connecting column 202f, a limiting slider 202g, and a first compression spring 202h. The sliding column 202e is slidably connected to the rotating cylinder 202b. The first connecting column 202f is fixedly connected to the sliding column 202e, and the first connecting column 202f cooperates with the second sliding groove 202b-1. By pushing the sliding column 202e, the sliding column 202e slides to drive the abutting cylinder 202c to rotate through the cooperation of the first connecting column 202f and the second sliding groove 202b-1. The rotation of the abutting cylinder 202c drives the rotating disk 202a to rotate. The limiting slider 202g is arranged at the end of the sliding column 202e. The first compression spring 202h is arranged between the rotating cylinder 202b and the sliding column 202e. The first compression spring 202h is used for the reset of the rotating cylinder 202b and the sliding column 202e.

[0045] Furthermore, the first decelerating member 203 includes a sliding connecting rod 203a, a second connecting column 203b, a friction block 203c, and a second compression spring 203d. The sliding connecting rod 203a is slidably connected to the fixed arc plate 201a and the first sliding groove block 101e. The second connecting column 203b is fixedly connected to the sliding connecting rod 203a, and the second connecting column 203b cooperates with the first sliding groove 202a-1. The rotation of the rotating disk 202a drives the sliding connecting rod 203a to slide through the cooperation of the second connecting column 203b and the first sliding groove 202a-1. The sliding of the sliding connecting rod 203a drives the friction block 203c to abut against the first rotating bead 201b to decelerate the first rotating bead 201b, so as to decelerate the rotation of the support cross bar of the cable reel and the cable reel, thereby realizing the decelerated wire release of the cable reel. The friction block 203c is slidably connected to the end of the sliding connecting rod 203a. One end of the second compression spring 203d is fixedly connected to the sliding connecting rod 203a, and the other end of the second compression spring 203d is fixedly connected to the friction block 203c. The second compression spring 203d enables the friction block 203c to slide in the sliding connecting rod 203a, and the second compression spring 203d enables the friction block 203c to abut against the first rotating bead 201b, realizing the initial deceleration of the cable reel.

[0046] Further, the second speed reducer 204 includes an abutting shell 204a, a limiting block 204b, an abutting column 204c, and a first tension spring 204d. The abutting shell 204a is slidably connected to the abutting block 202d. A pressure reduction groove 204a-1 is provided in the middle of the abutting shell 204a. The limiting block 204b is fixedly connected to the abutting shell 204a and is used to prevent the abutting shell 204a from rotating. The pressure reduction groove 204a-1 cooperates with the support cross bar of the cable reel. The abutting column 204c is fixedly connected to the abutting shell 204a and cooperates with the abutting block 202d. When the rotating cylinder 202b, the abutting cylinder 202c, and the abutting block 202d rotate, the abutting column 204c and the abutting block 202d cooperate to drive the abutting shell 204a to slide upward, so that the abutting shell 204a abuts against the support cross bar of the cable reel, causing the support cross bar of the cable reel and the cable reel to stop rotating, realizing the immediate stop of the cable reel from paying out the cable, and avoiding the situation where the paid-out length is longer than the designed length. One end of the first tension spring 204d is fixedly connected to the abutting shell 204a, and the other end of the first tension spring 204d is fixedly connected to the abutting cylinder 202c. The first tension spring 204d is used for the reset of the abutting shell 204a.

[0047] Further, the sliding member 205 includes a sliding arc block 205a, a second tension spring 205b, a fixed column 205c, and a rotating frame 205d. The sliding arc block 205a is slidably connected to the first sliding groove block 101e, and a limiting sliding groove 205a-1 is provided on the sliding arc block 205a, which cooperates with the limiting sliding block 202g. One end of the second tension spring 205b is fixedly connected to the sliding arc block 205a, and the other end of the second tension spring 205b is fixedly connected to the first sliding groove block 101e. When the sliding arc block 205a slides, the cooperation between the sliding groove and the limiting sliding block 202g prevents the limiting sliding block 202g and the sliding column 202e from rotating when the limiting sliding block 202g and the sliding column 202e slide. The fixed column 205c is fixedly connected to the sliding arc block 205a. The rotating frame 205d is sleeved on the fixed column 205c and is rotatably connected to the fixed column 205c. The sliding member 205 further includes an operating slide rod 205e, a connecting groove 102a-2 block, and a sliding groove rod 205g. The operating slide rod 205e is slidably connected to the first sliding groove block 101e. The connecting groove 102a-2 block is fixedly connected to the operating slide rod 205e and cooperates with the rotating frame 205d. The sliding groove rod 205g is provided at the end of the operating slide rod 205e. By pushing the sliding groove rod 205g and the operating slide rod 205e, the connecting groove 102a-2 block slides. The sliding of the connecting groove 102a-2 block drives the rotating frame 205d to rotate through the cooperation between the connecting groove 102a-2 block and the rotating frame 205d, and the rotation of the rotating frame 205d abuts and drives the sliding arc block 205a to slide.

[0048] The remaining structures are the same as those in Embodiment 2.

[0049] Operation process: Push the sliding groove rod 205g and the operating slide rod 205e to slide the two connection grooves 102a. The sliding of the two connection grooves 102a drives the rotating frame 205d to rotate through the cooperation between the two connection grooves 102a and the rotating frame 205d. The rotation of the rotating frame 205d drives the sliding arc block 205a to slide by abutting. The sliding of the sliding arc block 205a drives the sliding column 202e and the first connecting column 202f to slide. The rotation of the rotating disk 202a and the rotating cylinder 202b is driven through the cooperation between the first connecting column 202f and the second sliding groove 202b-1. The rotation of the rotating disk 202a drives the sliding link 203a to slide through the cooperation between the second connecting column 203b and the first sliding groove 202a-1. When the second connecting column 203b slides in the contraction section 202a-1a, the connecting rod slides and contracts, so that the friction block 203c abuts against the first rotating bead 201b to decelerate the first rotating bead 201b. When the second connecting column 203b slides in the rotating section 202a-1b, the sliding link 203a stops sliding, realizing the initial deceleration of the cable reel; when the movement of the rotating disk 202a and the rotating cylinder 202b drives the second connecting column 203b to slide in the contraction section 202a-1a, the abutting column 204c slides on the plane of the abutting cylinder 202c. When the movement of the rotating disk 202a and the rotating cylinder 202b drives the second connecting column 203b to slide in the rotating section 202a-1b, the abutting shell 204a is driven to slide towards the support cross bar of the cable reel through the cooperation between the abutting column 204c and the abutting block 202d, so that the abutting shell 204a abuts against the support cross bar of the cable reel, and the support cross bar and the cable reel of the cable reel stop rotating, realizing the immediate stop of cable unreeling of the cable reel, and solving the problem that the cable unreeling rack lacks a deceleration stop mechanism and affects the working efficiency.
