Description

cable tensioner

technical field

The invention belongs to the field of power system auxiliary tools, and in particular relates to a cable stretcher which can be operated by a single person and can stretch multiple cables at the same time.

Background technique

When a cable is about to be laid in the cable trough, it is necessary to make a cable head at the end of the cable, and connect two cables on one side. The wire is straightened before the cable head can be made. The method of straightening the cables is that one person steps on a section of a cable to prevent the cables from coming out of the cable groove, and another person uses a vise to straighten the cables one by one. The whole process is time-consuming and laborious. , At least two people are required to cooperate with the operation, and once the staff operating the vise loses their hands, the backward force is likely to cause injury to this person.

Contents of the invention

The object of the present invention is to overcome the deficiencies in the prior art and to invent a cable tensioner that can be operated by a single person and can stretch multiple cables at the same time.

The present invention is achieved in the following way: a cable stretcher, characterized in that it includes a fixed plate, a stretched plate and a foot pedal, the fixed plate to which it belongs is in the shape of a strip, and one end of the fixed plate is provided with a plurality of pairs of mutual Parallel ear plates, the ear plate is provided with a pressure plate, the pressure plate and the ear plate are fixed and connected by bolts, the other end of the fixed plate is provided with a rotating shaft and a stud connected to the pedal, and the stretching plate is fixed through the rotating shaft. The boards are connected, and the top of the attached stretching board is equipped with a crimping pliers, a section of the stretching board is used as a handle of the crimping pliers and a clamping plate, and the other half of the crimping pliers is formed by a shaft and a section of the stretching board. Wire pliers, one section of the stretching plate is connected to the other half of the crimping pliers in a scissors shape, and the inner side of the jaws of the crimping pliers is provided with diamond patterns; the pedal is long, and the two ends of one end of the pedal are Both sides are equipped with guard plates that are bent upwards. The guard plates on the left and right sides of the pedal are parallel to each other. There are multiple groups of stud holes penetrating through the upper and lower board surfaces on the pedals in between, and reinforcing ribs are arranged on the pedals.

Further, the upper plate surface of the pedal is vertically provided with a card slot vertical plate, the card slot vertical plate is arc-shaped, the card slot vertical plate is provided with continuous right-angled triangular tooth grooves, and the lower plate surface of the stretching plate is There are two supporting ear plates parallel to each other. There are columnar clips on the ear plates. The cross-section of the head of the clip is a right triangle. The tail of the clip is a handle. There is a spring in the middle of the clip. The head, the head of the clip is in contact with the right-angled triangular alveolar on the vertical plate of the card slot.

The present invention has the following advantages:

According to the length of the cable, after adjusting the position of the pressure plate on the fixed plate during use, press a section of the cable with the pressure plate on the fixed plate, then pull the end of the cable, and press it with a crimping pliers. Hold the pedals with your feet to maintain the balance of the whole device, and then press down on the stretching plate to straighten the multi-heel cables at one time by one person. Furthermore, the foot pedal and the stretching plate can be provided with a card slot vertical plate and a clip that cooperate with each other for stretching and positioning. When the operator presses the stretching plate downward, the clip on the stretching plate will slide to A triangular alveolar on the upper and lower parts of the card slot vertical plate can achieve the function of positioning and locking. When the stretching is completed, pull the clip to release the locking.

The device has an ingenious structure, which is convenient for one person to operate, saves time and effort, and the direction of force is downward. Even if the crimping pliers are off-line, the user can still perform protective actions during the downward process to reduce injuries.

detailed description

As shown in Figure 1, Figure 2 and Figure 3, a cable tensioner includes a fixed plate 1, a stretched plate 2 and a pedal 3, the fixed plate 1 is in the shape of a long strip, and one end of the fixed plate 1 There are seven pairs of ear plates 4 parallel to each other. The upper and lower surfaces of the ear plates 4 are flush with the fixed plate 1. A pressure plate 5 is arranged on the ear plate 4. The pressure plate 5 and the ear plate 4 are fixedly connected by bolts. The fixed plate 1 The upper plate surface of the other end is provided with rotating shaft 6 and pedal connecting stud, stretching plate 2 is connected with fixed plate 1 by rotating shaft 6, and the top of described stretching plate 2 is provided with crimping pliers 7, stretching One section of plate 2 is used as a handle and jaw pressing plate of crimping pliers 7, and the other half of crimping pliers 7 forms crimping pliers through shaft and stretching plate 2, and one section of stretching plate 2 and crimping pliers 7 The other half is connected in the shape of scissors, and the inner side of the jaws of the crimping pliers 7 is provided with a diamond pattern; the pedal 3 is in the shape of a strip, and both sides of one end of the pedal 3 are provided with an upwardly bent guard plate 8. The guard plates 8 on the left and right sides of the pedal 3 are parallel to each other, and the distance between the guard plates 8 on the left and right sides is equal to the width of the connecting studs provided with the pedal on the fixed plate 1. The pedals between the guard plates There are multiple sets of stud holes that run through the upper and lower surfaces of the board. The stud holes match the connecting studs of the pedals to select the appropriate length. The pedals are provided with reinforcing ribs to ensure that they can withstand larger loads. force.
