Description

Take-up and pay-off tools

technical field

The utility model relates to a retracting and releasing tool, in particular to a retracting and releasing tool for measuring ground resistance.

Background technique

The size of the grounding resistance is directly related to whether the grounding device of the electrical equipment is well grounded. In the annual routine test cycle, the electrical test team must use the compensation method to measure the grounding resistance of the main network of each substation in the jurisdiction. When measuring the grounding resistance, it is necessary to retract and release the current and voltage wires. However, since there is no special wire retracting tool, at least 3 people are required to retract and release the wires at the same time before and after the measurement. The work efficiency is low, and the phenomenon of wire winding often occurs in the take-up and take-off, which is time-consuming and laborious; according to statistics, the average take-up and take-off time is 66.2 minutes, accounting for 92.6% of the total measurement time. It can be seen that due to the low efficiency of take-up and take-off, pulling The whole measurement time is prolonged, resulting in low work efficiency.

Therefore, need to design a kind of special-purpose take-up and pay-off tool, can shorten the take-up and take-off time during work, reduce labor load, improve labor efficiency.

Contents of the invention

In view of this, the utility model provides a wire retracting and unwinding tool, which can shorten the time for retracting and unwinding the wire during work, reduce labor, and improve labor efficiency.

The wire take-up and pay-off tool of the present utility model comprises a support frame with rollers at the bottom. There is a drag bar.

Further, the support frame is provided with a rolling bearing, and the rolling shaft is rotatably matched with the support frame through the rolling bearing;

Further, the two ends of the rolling shaft are covered with a cable disc;

Further, there is a line dividing plate between the line discs at both ends of the rolling shaft;

Further, the support frame is provided with a line distribution plate parallel to the axial direction of the rolling shaft, and two windows are opened on the line distribution plate, and the two windows correspond to both sides of the line distribution plate;

Further, the length of the drag bar is adjustable;

Further, the drag bar is a door-shaped frame, on which is connected a door-shaped extension part that rotates with it. The door-shaped extension part is provided with a clamping frame, and the door-shaped extension part can be dragged through the clamping frame. The rods snap together.

The beneficial effect of the utility model is that: when the utility model is in use, the wires are regularly wound on the rolling shaft. Since the bottom of the support frame is equipped with rollers, the drag bar drags the tool while moving and unwinds the wire when unwinding. Turn the take-up handle to take up the line; the utility model saves the time for lapping the wires and cleaning the winding of the wires, thus shortening the time for taking up and unwinding the wires, thereby shortening the time for measuring the grounding resistance and improving labor efficiency. The utility model has good portability and is convenient for retracting and unwinding, and only one person is required to complete the retracting and unwinding, which greatly reduces the number of staff and saves labor. In addition, the utility model can also avoid the inaccurate measurement caused by the lack of wires.

Description of drawings

In order to make the purpose, technical solutions and advantages of the present utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings, wherein:

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

Detailed ways

Preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

Fig. 1 is the structure schematic diagram of the present utility model, as shown in the figure, the take-up and pay-off tool of the present utility model comprises the support frame 1 (in the present embodiment, only one side is equipped with rollers, and the other side is support feet, of course, four corners can also be installed with rollers), the horizontal frame on the support frame 1 is provided with a rolling shaft 3 that rotates with it, and the end of the rolling shaft 3 is provided with a take-up handle 4, and the support frame 1 Connected with a drag bar 5; earlier lead wires are regularly wound on the rolling shaft 3, and the tool is dragged by the drag bar 5 when unwrapping while advancing, and when the line is taken up, the take-up handle 4 is rotated to take up the line.

As a further improvement of the utility model, the support frame 1 is provided with a rolling bearing 6, and the rolling shaft 3 rotates with the support frame 1 through the rolling bearing 6; the rolling bearing 6 changes the sliding friction between the rolling shaft 3 and the support frame 1 For rolling friction, thereby making rolling shaft 3 rotate more smoothly, reduce frictional loss.

As a further improvement of the utility model, the two ends of the rolling shaft 3 are covered with wire reels 7; the wire reels 7 are used to clamp and limit the wires, especially when there are many wires wound on the wire rolling shaft 3, it can effectively prevent the wires from scattering.

As a further improvement of the utility model, there is a distribution disc 8 between the wire reels 7 at both ends of the rolling shaft 3; the function of the distribution disc 8 is to separate two kinds of wires. and voltage wires, therefore, a wire distribution disc 8 can play the role of separating the current and voltage wires; because usually the required current wires are more than the voltage wires, the length of the rolling shaft 3 on one side of the wire distribution board 8 in the figure is longer than that of the voltage wires. Long, the wire reel 7 diameter is bigger, is used for winding current wire, and the rolling bobbin 3 length of the other side is shorter, and wire reel 7 diameter is less, is used for winding voltage wire.

As a further improvement of the present utility model, the support frame 1 is provided with a line distribution plate 9 parallel to the axial direction of the rolling shaft 3, and two windows are opened on the line distribution plate 9, and the two windows are connected to the line distribution plate 8 respectively. Corresponding on both sides; the line distribution plate 9 is installed in parallel in front of the rolling shaft 3, and the two kinds of wires pass through the two windows respectively, and are respectively wound on the rolling shafts 3 on both sides of the line distribution disc 8, which is convenient for the two types of wires in the process of winding and unwinding. separation.

As a further improvement of the utility model, the length of the drag rod 5 is adjustable; There is a clamping frame 11 on the top, and the door-shaped extension 10 can be locked with the drag bar 5 through the clamping frame 11; when the length of the drag bar 5 is not enough, the door-shaped extension 10 can be turned to the top to make the clamp The frame 11 clamps the drag rod 5, which is easy to use and convenient for carrying; of course, the drag rod can also be designed as a pull rod style similar to a trolley box, and the length of the drag rod can be adjusted by using a telescopic sleeve structure.

The utility model is preferably made of stainless steel material, with high strength and corrosion resistance; according to experimental verification, after using the utility model, the average retracting and releasing time is shortened to 41 minutes, which is 66.2 minutes before use. The pay-off time has been shortened by nearly 40%. Before using the tool, at least 3 people are required to take up and pay off the wire at the same time. After use, only one person can complete it, which reduces the amount of labor and improves labor efficiency.

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described with reference to the preferred embodiment of the utility model, those of ordinary skill in the art should understand that, Various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
