Description
Technical Field
[0001] The utility model relates to the technical field of wire winding machines, in particular to a wire winding device for power distribution engineering. Background Art
[0002] The power system is composed of power generation, transmission, transformation, distribution, power consumption and dispatching. The power distribution is mainly carried out by the distribution network, which is the link in the power system that is directly connected to the user and distributes electric energy to the user. It mainly receives electric energy from the power grid and distributes it step by step. The distribution network is composed of a variety of distribution equipment and distribution facilities, and the transmission lines of different specifications connect these components together to form a distribution network. The distribution project is the project that connects these equipment or facilities.
[0003] The main work of power distribution engineering is cable laying, and whether it is laying new cables or winding old cables, a wire winding machine will be used. The main body of the wire winding machine is supported by a support frame, and a winding shaft is rotatably installed on the support frame. The cable is wound and wound on the winding shaft by driving the winding shaft to rotate. However, the amount of cables covered by power distribution engineering is large, and the cables are easily wound locally and not wound evenly when winding, which leads to problems such as messy cables or knots. Therefore, there is a need for a wire winding machine that can assist in cable arrangement in the market.
[0004] In the patent document with the announcement number CN 215516136 U, a cable winding device for power distribution engineering is disclosed, which mainly suspends a threaded rod on a supporting side plate, and a fixing ring is arranged on the threaded rod. The threaded rod is driven to rotate to drive the fixing ring to move along the axial direction of the rotating shaft, thereby guiding the cable to be evenly arranged on the driving shaft.
[0005] Although the above patent can drive the cables to be arranged in sequence on the shaft through fixed guidance, due to the large cable winding volume and long shaft in the power distribution project, when the shaft is winding the cables, the fixed ring constantly moves along the axial direction of the shaft, which not only causes a long interval, but also causes the cable to deviate when the fixed ring turns at both ends of the shaft, thereby causing the cables to be partially staggered and overlapped at both ends, affecting the balance and aesthetics of the winding; and as the cables are continuously wound, the size of the cable loops increases, and the length of the cable winding increases, requiring the moving speed of the fixed ring to be constantly adjusted. Once the moving speed of the fixed ring is too fast relative to the shaft speed, the axial spacing of the cable winding will become larger, affecting the uniformity of the winding, and if the speed of the fixed ring is too slow relative to the shaft speed, the cable will be partially wound, making the operation and control more troublesome.
[0006] To this end, the utility model provides a cable winding device for power distribution engineering, which avoids partial overlapping of cables at both ends of a rotating shaft and improves the convenience of cable winding control. Utility Model Content
[0007] The utility model aims to solve the problems existing in the prior art and proposes a wire winding device for power distribution engineering.
[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0009] A wire winding device for power distribution engineering comprises a wire winding drum, a rotating shaft is rotatably installed inside the wire winding drum, a plurality of wheels are arranged on the rotating shaft at intervals, an opening is provided on the side wall of the wire winding drum, a wire clip is slidably installed along the axial direction of the wire winding drum at the opening, and the wire clip is threadedly connected to a lead screw rotatably installed on the side wall of the wire winding drum.
[0010] Preferably, the annular array of the wheel disc side wall has a plurality of notches.
[0011] Preferably, the winding drum comprises a barrel and detachable covers at both ends of the barrel.
[0012] Preferably, the wheel disc is detachably connected to the rotating shaft.
[0013] Preferably, a sleeve is sleeved on the rotating shaft, and the wheel disc is detachably mounted on the sleeve.
[0014] Preferably, the rotating shaft passes through the winding drum, a frustum is provided at the rear end of the rotating shaft, a positioning cylinder is threadedly mounted on the end surface of the winding drum, and a conical surface matching the frustum is provided on the inner wall of the positioning cylinder.
[0015] Preferably, a friction layer is provided between the frustum and the conical surface.
[0016] Compared with the prior art, the utility model provides a wire winding device for power distribution engineering, which has the following beneficial effects:
[0017] There are multiple wheels on the shaft, which divide the shaft into independent winding chambers. When in use, the shaft rotates to reel in the cable. When the winding chamber is full, the wire buckle moves to the corresponding position of the next winding chamber and guides the cable to the side winding chamber. As the shaft continues to rotate, the cable will be reeled in the winding chamber. This division through multiple winding chambers not only avoids the problem of overlapping winding when the cable changes direction at both ends of the shaft, but also makes the cable winding more evenly dispersed and beautiful; and the wire buckle does not need to be driven continuously, so there is no need to change the moving speed with the change of the size of the cable loop, thereby reducing the difficulty of operation and control and improving the convenience of operation.

[0032] When in use, the cable end wire is passed through the wire hole, and then extended into the winding drum 1 from the opening and confined on the rotating shaft 2; then the rotating shaft 2 is driven to rotate, and the rotating shaft 2 rotates to reel the cable, and the multiple wheels 3 divide the rotating shaft 2 into independent winding chambers 11. When the winding chamber 11 is full of reeled cables, the lead screw 5 is driven to rotate, and the lead screw 5 drives the wire buckle 6 to move to the corresponding position of the next winding chamber 11. At this time, the guide buckle will guide the cable to deviate to the winding chamber 11 on the side, and as the rotating shaft 2 continues to rotate, the cable will be reeled in the winding chamber 11.

[0036] In a further embodiment of the present scheme, a sleeve is sleeved on the rotating shaft 2, and the wheel 3 is detachably mounted on the sleeve; the sleeve is sleeved on the rotating shaft 2 and axially slides with the rotating shaft 2, or the sleeve is fastened to the rotating shaft 2 by a countersunk screw, and the wheel 3 is detachably mounted on the sleeve by a countersunk screw, so that the wound cable can be removed from the rotating shaft 2 synchronously with the sleeve. When all the winding cavities 11 on a single sleeve are full of cables, the cover 102 is removed to take out the sleeve, and then the empty sleeve and the wheel 3 are replaced, so that the equipment can be reused, thereby improving the flexibility and practicality of the equipment.
[0037] In a further embodiment of the present scheme, the rotating shaft 2 passes through the winding drum 1, a frustum 10 is provided at the tail end of the rotating shaft 2, a positioning cylinder 9 is threadedly mounted on the end face of the winding drum 1, and the inner wall of the positioning cylinder 9 is provided with a conical surface matching the frustum 10.
[0038] Principle details of this embodiment:
