The utility model adds two symmetrically arranged cam discs on the basis of common twisted coils, and the cam discs rotate. Due to the particularity of the structure, the gap between the two cam discs is always changing, so that the cam discs passing through the gap The compression force on the cable is constantly changing, but it will not crush the cable, so that when manually dragging, you can feel the tension of the cable very well, which is easy to adjust at any time, and the rubber bump is even more It can increase this tactile feeling, which is convenient for construction personnel to feel and improve the efficiency of power engineering construction.

Description

Automatic take-up and release device for electric power engineering

technical field

The utility model relates to an automatic take-up and release device for electric power engineering.

Background technique

In the known technical field, in electric power engineering, wiring is one of the important processes, and it is also the work with the largest workload. Generally, in actual construction, the cables will cooperate with the twisting reel to carry out the wire-releasing operation. In order to ensure the whole process Generally, this process adopts the form of mechanical and manual assistance. When the cable is retracted or unwound, its tension force is mainly adjusted passively through the twisting reel. When the cable is manually pulled, the cable cannot be well controlled. Since the tension force mainly depends on manual dragging, it is very important whether it is convenient for the construction personnel to adjust the tension and facilitate the dragging action.

Utility model content

The technical problem to be solved by the utility model is: to overcome the above problems, to provide an automatic take-up and release device for electric power engineering, which can facilitate the construction personnel to adjust the tightness of the cable during wiring, and provide a good hand feel, and improve the safety of electric power construction. efficiency.

The technical solution adopted by the utility model to solve the technical problem is: an automatic wire retracting and releasing device for electric power engineering, including a fixed bracket and a twisting reel installed on the fixing bracket, and a cable is wound on the twisting reel, An L-shaped bracket is provided on the outlet direction of the cable, and an annular sleeve with a waist-shaped cross section is installed on the protruding end of the L-shaped bracket. The ends are hinged and fixed, and an upper cam disc and a lower cam disc are respectively arranged on the upper and lower sides in the annular sleeve, and the upper cam disc and the lower cam disc are both driven by a separate motor shaft, and the motor shaft All are slidably installed in the annular sleeve, and several rubber raised blocks are provided on the outer contours of the upper cam disc and the lower cam disc, and the cables pass through the area between the upper cam disc and the lower cam disc.

Further, as a specific embodiment, in the present utility model, the upper cam disc rotates in the counterclockwise direction, the lower cam disc rotates in the clockwise direction, and the upper cam disc and the lower cam disc are arranged symmetrically. .

The beneficial effects of the utility model are: the utility model has a simple structure, and two symmetrically arranged cam discs are added on the basis of the common winch disc, and the cam discs rotate, and due to the particularity of the structure, the two cam discs The gap between them is always changing, so that the compression force on the cable passing through the gap is constantly changing, but it will not crush the cable, so that when manually dragging, you can feel the tension of the cable well. , easy to adjust at any time, and the rubber bumps can increase this tactility, which is convenient for construction personnel to feel and improve the efficiency of power engineering construction.

Fig. 1 is a structural representation of the utility model;

Among the figure: 1. fixed bracket, 2. twisting coil, 3. cable, 4. L-shaped bracket, 5. ring sleeve, 6. upper cam disc, 7. lower cam disc.

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

The preferred embodiment of the automatic take-up and pay-off device for electric power engineering of the present invention as shown in Figure 1 comprises a fixed support 1 and a twisted reel 2 installed on the fixed support 1, and a cable 3 is wound on the twisted reel 2, On the outlet direction of cable 3, an L-shaped support 4 is provided, and an annular sleeve 5 with a waist circle shape in cross section is installed on the protruding end of the L-shaped support 4. The protruding end is hinged and fixed, and the upper and lower sides in the annular sleeve 5 are respectively provided with an upper cam disc 6 and a lower cam disc 7, and the upper cam disc 6 and the lower cam disc 7 are all driven by a separate motor shaft 8, and The motor rotating shaft 8 is all slidably installed in the annular sleeve 5. Adjusting the up and down position of the motor rotating shaft 8 can assist in adjusting the distance between the upper cam disc 6 and the lower cam disc 7. The outer contours of the upper cam disc 6 and the lower cam disc 7 Several rubber bumps 9 are arranged on the top, and the cable 3 passes through the area between the upper cam disc 6 and the lower cam disc 7 .

The upper cam disc 6 rotates in the counterclockwise direction, and the lower cam disc 7 rotates in the clockwise direction, so as to keep consistent with the outgoing direction of the cable, and the upper cam disc 6 and the lower cam disc 7 are symmetrically arranged, and also It can be set asymmetrically, and it can play the role of constantly adjusting the gap between them.
