Description

Technical Field

[0001] The utility model belongs to the technical field of cable retracting and releasing devices, and particularly relates to a pull rod vehicle for cable retracting and releasing. Background Art

[0002] The Cable Retraction and Payout Trolley is a portable cable management tool designed for industries such as telecommunications, broadcasting, power generation, and construction. It aims to improve the efficiency and convenience of cable laying, maintenance, and recycling. This product integrates cable storage, rapid cable retraction and payout, and mobile transportation. Its lightweight construction and user-friendly design ensure easy operation, labor-saving efficiency, and high efficiency.

[0003] For example, a dual network cable pull rod vehicle disclosed in a Chinese utility model patent (authorization announcement number CN211338370U) combines network cables, optical fibers and other cables on the same device, which can simultaneously reel in and unreel network cables, optical fibers, etc. with less physical effort, thereby improving work efficiency. Through the design of the pull rod device, network cables, optical fibers and other cables can be quickly moved to a certain place without wasting physical effort in carrying them.

[0004] The above-mentioned prior art cable reel has a suspended bottom structure. The original intention of this design may be to facilitate flexible cable retraction and management. However, in actual application, as the cable reel gradually fills up with cables, the weight of the cables it carries will increase significantly, resulting in a significant increase in the total weight of the entire cable reel system.

[0005] As cables accumulate, the vertical load on the take-up reel increases dramatically. Because the bottom of the take-up reel is suspended in the air and lacks a direct support structure to distribute this added weight, the suspended end of the reel becomes the most vulnerable link in the entire system. Under prolonged use or excessive load, the suspended end may deform, break, or suffer other damage due to the excessive pressure. This not only affects the normal use of the reel, but can also cause unnecessary damage to the cables themselves and even pose a safety hazard. Utility Model Content

[0006] The purpose of the present utility model is to provide a trolley for cable reeling and reeling, aiming to solve the problem of the vertical load on the reel increasing rapidly as the cables continue to accumulate. Since the bottom is suspended in the air and there is a lack of a direct support structure to distribute the increased weight, the suspended end of the reel becomes the most vulnerable link in the entire system. Under prolonged use or excessive load, the suspended end may deform, break, or suffer other forms of damage due to the inability to withstand the excessive pressure. This not only affects the normal use of the reel, but may also cause unnecessary damage to the cables themselves and even pose a safety hazard.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A trolley for cable winding and unwinding, including a trolley, on both sides of the vertical frame of the trolley, a winding disc for cable winding and unwinding is respectively installed, at the bottom of the central end of the vertical frame of the trolley, a bottom plate is fixedly installed, and on the surface of the bottom plate, a guide rail is fixedly installed;

[0008] On the surface of the guide rail, a support member is movably installed, through the central end of the support member, a screw rod is installed, one end of the screw rod is threadedly connected inside a threaded sleeve, the other end of the threaded sleeve is fixedly installed on the outer wall of a fixing plate, at the bottom of the fixing plate, it is fixedly installed on the surface of a reinforcing rod, and at the bottom of the reinforcing rod, it is fixedly installed on the surface of the bottom plate.

[0009] In order to reduce the friction when the support member moves on the bottom plate, as a trolley for cable winding and unwinding of the present utility model, preferably, on one side outer wall of the support member, an arc-shaped concave edge is provided, the surface of the arc-shaped concave edge supports on the bottom of the disc of the winding disc, inside the support member, two groups of notches are provided, inside the notches, a ball is movably installed, the bottom of the ball is movably in contact with the inner wall of a chute, the chute is opened on the surface of the bottom plate, both ends of the reinforcing rod are fixedly connected with the outer wall of a guide rail respectively, the screw rod is located at the position of the horizontal midline between two guide rails, and on both sides of the screw rod, a chute is also respectively provided.

[0010] In order to enable the screw rod to drive the support member to move towards the edge of the bottom plate when moving to one side, as a trolley for cable winding and unwinding of the present utility model, preferably, on the surface of the screw rod, a fixing disc is also fixedly installed, and one side of the fixing disc presses against the outer wall of the support member.

[0011] In order to enable the support member to support under the winding disc and strengthen the load-bearing capacity of the suspended end of the winding disc, as a trolley for cable winding and unwinding of the present utility model, preferably, the inner wall of the arc-shaped concave edge is of an arc-shaped structure, and the support member is made of deformable hard rubber material, and the bottom of the bottom plate and the bottom of the trolley are at the same horizontal height.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] After the winding disc winds up the cable, at this time, the screw rod is adjusted outwards. As the screw rod moves, the fixing disc on the screw rod will drive the support member to move towards the edge of the bottom plate. When the support member starts to contact the winding disc, at this time, under the continuous action of the screw rod, the support member will slightly deform, so that the arc-shaped concave edge of the support member will complete the docking with the disc on the winding disc. In this way, the support member can support on the bottom of the suspended end of the winding disc through the bottom plate. In actual use, this structure can effectively enhance the load-bearing capacity of the winding disc, thereby improving the use safety of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 5 , the present utility model provides the following technical solutions: A trolley for cable winding and unwinding, including a trolley 1. On both sides of the vertical frame of the trolley 1, a take-up reel 2 for cable winding and unwinding is respectively installed. At the bottom of the center end of the vertical frame of the trolley 1, a bottom plate 3 is fixedly installed. On the surface of the bottom plate 3, a guide rail 4 is fixedly installed;

[0023] At the bottom of the bottom plate 3, two groups of universal wheels are provided. When the trolley 1 moves, the bottom plate 3 can also move synchronously through the universal wheels at the bottom.

[0024] A support member 5 is movably installed on the surface of the guide rail 4. A screw rod 6 is installed through the center end of the support member 5. One end of the screw rod 6 is threadedly connected inside a threaded sleeve 7, and the other end of the threaded sleeve 7 is fixedly installed on the outer wall of a fixing plate 8. The bottom of the fixing plate 8 is fixedly installed on the surface of a reinforcing rod 11, and the bottom of the reinforcing rod 11 is fixedly installed on the surface of a bottom plate 3.

[0025] Preferably: An arc-shaped concave edge 501 is formed on the outer wall of one side of the support member 5, and the surface of the arc-shaped concave edge 501 supports the bottom of the disk of the wire reel 2. Two sets of notches 502 are formed inside the support member 5. A round bead 10 is movably installed inside the notch 502, and the bottom of the round bead 10 is movably in contact with the inner wall of a sliding groove 9. The sliding groove 9 is formed on the surface of the bottom plate 3. The inner wall of the arc-shaped concave edge 501 is of an arc-shaped structure, and the support member 5 is made of deformable hard rubber material. The bottom of the bottom plate 3 and the bottom of the trolley 1 are at the same horizontal height.

[0026] During specific use, two sets of symmetric round beads 10 are arranged inside the support member 5. When the support member 5 moves, the round beads 10 will roll on the surface of the bottom plate 3, which can improve the convenience of the support member 5 moving on the bottom plate 3.

[0027] Two through holes are also formed on both sides of the support member 5, and the guide rail 4 is installed inside the through holes. When the support member 5 moves, it will move directionally on the bottom plate 3 along the track of the two guide rails 4.

[0028] Preferably: A fixed disk 12 is also fixedly installed on the surface of the screw rod 6, and one side of the fixed disk 12 presses against the outer wall of the support member 5. Both ends of the reinforcing rod 11 are fixedly connected to the outer wall of a guide rail 4 respectively. The screw rod 6 is located at the horizontal midline position between the two guide rails 4, and a sliding groove 9 is also arranged on both sides of the screw rod 6 respectively.

[0029] During specific use, when the wire is wound up on the wire reel 2, at this time, the disks on both sides of the wire reel 2 will be in a suspended state. In order to reduce the pressure borne by the wire reel 2 when suspended, the screw rod 6 can be adjusted outwards at this time.

[0030] Rotate the screw rod 6, and the screw rod 6 will move outwards from inside the threaded sleeve 7, and the fixed disk 12 will also move synchronously when the screw rod 6 moves. In this way, the fixed disk 12 can drive the support member 5 to move simultaneously under the drive of the screw rod 6. When the support member 5 moves to the bottom of the wire reel 2, it will be initially blocked at this time, and the adjustment force on the screw rod 6 is increased. In this way, the arc-shaped concave edge 501 on the support member 5 will contact the suspended end disk of the wire reel 2. Thus, the support member 5 and the bottom plate 3 can support the suspended end of the wire reel 2, and the load-bearing capacity of the suspended end of the wire reel 2 can be improved through this structure.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
