Description

Pull system

technical field

The utility model belongs to the mechanical field, and relates to a mechanical structure for dragging wires and cables, in particular to a wire pulling system.

Background technique

During the use of high-voltage equipment, regular maintenance is generally carried out to solve some potential safety hazards and avoid equipment and wire loss due to long-term use; during high-voltage power maintenance, although the high-voltage equipment will be powered off, there may be sudden calls, In the case of reverse power transmission or induction power, in order to prevent the staff from getting an electric shock and ensure safe work, a ground wire connected to high-voltage equipment is generally installed, and the lower end of the ground wire is driven into the ground to prevent leakage of electricity from harming the staff;

After the overhaul is completed, the ground wire needs to be recovered. Since the ground wire is driven into the ground, many people need to work together to pull it out. Sometimes, when it is difficult to pull it out manually, it is necessary to use a large tool to pull out the wire, which is not only time-consuming and laborious. And the cost is high and time-consuming.

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in further detail.

The pull wire system of the utility model includes a cable connection part and a force application part connected with the cable connection part. The force application part includes a mounting frame 1, a gear set installed on the mounting frame and two ends fixedly connected to the mounting frame respectively. and the cable 2 of the cable connection part; the gear set includes a master gear 3, a slave gear 4 engaged with the master gear, a ratchet 5 coaxially fixed with the slave gear, and the main shaft of the master gear, the slave gear and the ratchet are in common The shaft-mounted slave shafts are all fixedly connected to the mounting frame, and the end of the slave shaft is fixedly connected with a handle 6 perpendicular to the slave shaft. The ratio of the diameter of the main gear to the diameter of the slave gear is 1.5-4:1.

When not in use at ordinary times, the pull wire of the pull wire system can be wound on the main shaft of the main gear for convenient storage and placement. When performing wire pulling operation, the cable connection part is fixedly connected with the cable to be pulled. The operator holds the installation frame with one hand and turns the handle with the other hand to drive the ratchet and the slave gear to rotate. Since the slave gear meshes with the master gear, the master gear is pulled Starting from the rotation driven by the gear, the cable wound on the main shaft is gradually tightened or loosened, and the force on the pulled cable gradually increases with the tension of the cable, and finally the pulling operation or pulling is realized.

With the utility model, one operator can complete the operation, and the design of the handle and the master and slave gear meshes greatly reduces the labor intensity of the operator. At the same time, the force on the cable can be increased sequentially instead of abruptly, avoiding the sudden change of the cable. The situation of pulling out or breaking due to force occurs, which improves the operating safety. The main gear and the slave gear mesh, and the tooth pitch is roughly the same. Set the diameter ratio of the main gear and the slave gear at an appropriate ratio of 1.5-4:1. If the ratio is too large, the size and weight of the main gear will increase. The applied force should also be increased. If the ratio is small, the number of turns the operator can rotate the handle will be increased, and the operation time will be prolonged. It is more appropriate to set the diameter ratio at 2:1.

The function of the cable connection part is to occlude the cable to be pulled, which can be a hook, a wire clip, a pull ring, etc. In the utility model, the hook 8 is preferably used. The reliability of the hook is stronger than that of the wire clip, and it is convenient to hook the cable regardless of the wire. Whether cable has free end, come off from hook 8 in order to prevent pulled cable, can be provided with locking plate 9 at the fixed end of hook, after hook hooks up cable, the locking plate end is buckled dead on the hook free end. the

Yet another preferred embodiment: the installation frame is also fixed with a movable rotating shaft, and a cable guide sleeve 7 is fixed on the movable rotating shaft. Pass the cable through the cable guide sleeve. When in use, with the rotation of the movable shaft, the cable guide sleeve will position the direction of the cable to avoid uneven force caused by the large swing of the cable. the

Preferably, there is a pull ring on the top of the installation frame, which is convenient for fixing the utility model on construction machinery such as a trailer, and is applied to occasions where manpower cannot complete the operation.

With the wire pulling system described in the utility model, the gear set is used to reduce the pulling force required for the wire pulling, and one operator can complete the wire pulling operation alone. In order to avoid the possible danger caused by the sudden disconnection of the unplugged wire.

The foregoing are various preferred embodiments of the present utility model. If the preferred implementations in each preferred embodiment are not obviously self-contradictory or based on a certain preferred implementation, each preferred implementation can be arbitrarily superimposed and combined. The specific parameters in the described embodiments and the embodiments are only for clearly expressing the utility model verification process of the utility model person, and are not used to limit the patent protection scope of the utility model, and the patent protection scope of the utility model is still defined by its claims. As the standard, all equivalent structural changes made by using the description and drawings of the utility model should be included in the protection scope of the utility model in the same way. the
