Description

Positive rod

technical field

The utility model relates to a tool for maintaining an inclined electric pole in an electric power system, in particular to a straightening device for straightening an inclined electric pole.

Background technique

In the 10 kV power grid, due to factors such as long-term operation, seasonal influence, or external force damage, there will be situations where the cement pole body is inclined, which seriously affects the normal operation of the power grid. Therefore, it is necessary to straighten the inclined cement pole.

The traditional righting method of cement poles is: under the premise of power failure, fix the hemp rope 1.7 meters below the live part of the cement pole, and then pull the hemp rope to straighten the pole by the operator. This righting method requires many people (eight to ten People) pull the hemp rope, and, due to the large inclination force of the rod body and the weight of the hemp rope, the rod body will be deflected every once in a while due to insufficient strength of the personnel, and the operator needs to work hard at the same time to pull the rod body back to the normal position. position, resulting in the "sawing phenomenon" (that is, the phenomenon of "returning-pulling back" many times), which can easily damage the rod body, cause cracks in the rod body or short rods. Therefore, the existing cement rod straightening method not only consumes a lot of The manpower and time, also increased the unsafe factor.

Utility model content

In view of this, the present application provides a rod straightening device to reduce manpower and time consumption in the cement rod straightening process, and reduce unsafe factors at the same time.

In order to achieve the above object, the utility model provides the following technical solutions:

A positive pole device, comprising:

Towing lines, wire clamps, reversing chains and ground anchors;

One end of the pulling wire is provided with a fixing frame, and the other end of the pulling wire is fastened by the wire clamp; The head is detachably connected; the other hook head of the inverted chain is detachably connected with the ground anchor.

As for the above positive rod device, preferably, the pulling wire is a steel wire rope or a steel strand.

For the positive pole device mentioned above, preferably, the ground anchor is a galvanized angle steel with a preset length.

It can be seen from the above scheme that a positive rod device provided by the embodiment of the present application includes a pulling wire, a wire clamp, an inverted chain and a ground anchor, wherein one end of the pulling wire is provided with a fixing frame. The fixing frame is fixed on the upper part of the cement pole, and the other end of the traction line is fastened by the wire clamp; the wire clamp is detachably connected to one hook head of the inverted chain through the pull ring on it; the other end of the inverted chain The hook head is detachably connected to the ground anchor. When the pole is straightened, the ground anchor is fixed on the ground, and only one worker is required to operate the reverse chain to straighten the cement pole, which reduces the time required for the cement pole to be straightened. Manpower and time consumption, while reducing unsafe factors.

In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the accompanying drawings that need to be used in the description of the embodiments or the prior art. Obviously, the accompanying drawings in the following description These are only some embodiments of the utility model, and those skilled in the art can also obtain other drawings based on these drawings without creative work.

Fig. 1 is a schematic structural view of a positive rod device provided in the embodiment of the present application;

Fig. 2 is a view of the use state of a positive rod device provided by the embodiment of the present application.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

A schematic structural diagram of a positive rod device provided in an embodiment of the present application is shown in Figure 1, including:

Traction line 1, wire catcher 2, chain reel 3 and ground anchor 4;

One end of the traction line 1 is provided with a fixing frame 11, and the fixing frame 11 is used to fix the cement rod by an operator when straightening the cement rod; specifically, it can be fixed at 1.7 meters below the live part of the cement rod, or it can be fixed on the cement rod 1.5 meters below the live part.

The other end of the pull wire 1 is fastened by the wire clamp 2, that is, the other end of the pull wire 1 is clamped in the wire clamp 2; how the wire clamp fastens the pull wire belongs to common knowledge in the art, and will not be repeated here.

Preferably, the traction line 1 can be a steel wire rope or a steel strand, and the traction line 1 can be a steel wire rope or a steel strand with a cross-sectional area of 12 mm ² , and of course other materials with sufficient bearing capacity can also be selected according to actual experience. The traction line and the like are not specifically limited here. For example, you can use the steel wire rope that has been eliminated due to partial damage on the pole machine (the machine used when erecting cement poles), as long as the damaged part is cut off.

The wire clamp 2 is detachably connected to a hook head of the inverted chain 3 through a pull ring on the wire clamp 2;

The other hook head of the inverted chain 3 is detachably connected with the ground anchor 4; Rings or holes are detachably connected; the inverted chain 3 can be selected with a lifting capacity of 2.5 tons.

The ground anchor 4 is fixed in the ground before the positive pole. Preferably, the ground anchor 4 can be a galvanized angle steel with a preset length, that is, the angle steel is used as a ground anchor. The length of the angle steel can be 1.6 meters, or other lengths, such as 1.7 meters, 1.8 meters, etc.; specifically, when a positive rod is needed, the ground anchor 4 is smashed into the ground, and when the ground anchor 4 is smashed into the ground, as shown in Figure 2, Figure 2 is the positive pole provided by the embodiment of the present application. The diagram of the use state of the rod tool, the ground anchor can be smashed into the ground perpendicular to the ground plane, or can be smashed into the ground perpendicular to (or approximately perpendicular to) the traction line.

In the pole straightening device provided by the embodiment of the present application, after the fixing frame of the traction line is fixed on the cement pole and the ground seedlings are fixed in the ground, only one operator is required to operate the reverse chain 3 to straighten the cement pole. There is no need to cut off the power during the straightening process, which reduces the manpower and time consumption in the straightening process of the cement pole, and reduces unsafe factors at the same time.

In actual operation, using the pole straightening device provided by the embodiment of the present application, only one person is required to operate the reverse chain, one person to monitor (that is, to monitor whether the cement pole has been straightened), and one person to cultivate the soil can complete the straightening of the cement pole, and the time required is the most It takes 30 minutes to correct the cement pole; while the existing positive pole method requires 10 minutes to check in (i.e. registration and start straightening), 10 minutes for power failure, 10 minutes for safety measures, 35 minutes for positive pole, and settlement (ie 10 minutes after the completion of registration and righting, 15 minutes to remove the safety measures, 10 minutes to power transmission, a total of 100 minutes; and this application, since there is no need for power outages, there is no need for check-in and check-out, and the regular The strength of the lever is balanced and stable, and there will be no "sawing" phenomenon, which can reduce the safety measures against the phenomenon of sawing. Therefore, the application of the positive lever provided by the embodiment of the present application can reduce the manpower and at least 65 minutes. Unsafe factors are also reduced.
