Description

Technical Field

[0001] The invention relates to the technical field of power transmission lines, and in particular to a guiding device for limiting the position of a cross arm of a concrete pole. Background Art

[0002] When laying transmission lines, new poles need to be built. The crossarms are usually installed manually on the poles, so workers need to transport the crossarms to the poles first, and then climb to the top of the poles to install them. This method requires operators to climb back and forth between the top of the pole and the ground many times, which easily causes the risk of falling objects and falling from heights.

[0003] In order to solve this problem, drones are usually used to transport and install crossarms. However, when using drones to install crossarms, it is impossible to properly limit the position of the crossarms, which makes the installation of the crossarms difficult.

[0004] In view of this, this application is hereby filed. Summary of the invention

[0005] In order to solve the problems of the prior art, the present invention provides a guiding device for limiting the cross arm of a concrete pole. By providing a guide cover with a conical structure that is small at the top and large at the bottom and a corresponding driving structure, the guide cover can be quickly and conveniently put on the pole and fixedly installed, thereby achieving the limiting and fixing effect on the cross arm.

[0006] The present invention is achieved through the following technical solutions:

[0007] A guiding device for limiting the position of a cross arm of a concrete pole, comprising a guiding cover body which is hollow inside and open at the bottom, wherein the guiding cover body is a structure which is small at the top and large at the bottom, and is used to move from top to bottom and be sleeved on the pole;

[0008] When the outer wall of the guide cover is subjected to a thrust toward the center of the guide cover or a pull away from the center of the guide cover, the guide cover can be tightened inwardly to clamp the pole or opened outwardly to loosen and exit from the top of the pole.

[0009] The guide cover of the present invention is used for limiting position. When the UAV carrying the guide cover reaches above the pole, the UAV descends so that the guide cover is put on the pole from top to bottom. Since the guide cover adopts a "small at the top and large at the bottom" structure, the guide cover can fall into the pole more conveniently. Then, the guide cover is tightened inward as a whole under the action of external thrust, so that it is fixed on the pole and plays a limiting role on the cross arm.

[0010] When the cross arm is installed, the guide cover expands outward as a whole under the action of external tension to release the fastening clamping state with the pole, and then the drone lifts the guide cover upward and removes it from the top of the pole.

[0011] In a specific embodiment, the guide cover body is a semi-conical structure that is small at the top and large at the bottom.

[0012] The present invention adopts a conical cylindrical structure, which can ensure that the guide cover body is more closely fitted to the side wall of the pole in a tightened state, thereby improving the clamping stability of the guide cover body.

[0013] In a specific embodiment, it also includes a plurality of electric telescopic rods arranged along the outer circumferential direction of the guide cover body, and the extension or shortening of the electric telescopic rods can control the tightening or opening of the guide cover body.

[0014] The present invention can realize automatic tightening or opening of the guide cover by arranging an electric telescopic rod. Before the start of work, when the drone lowers the guide cover to the pole, the front end of the electric telescopic rod is extended to a certain distance according to the actual width of the pole under the action of manual remote control of the operator, thereby applying an appropriate force to the guide cover, thereby achieving the strength of the guide cover and the pole to reach a tightened state.

[0015] In a specific embodiment, it also includes an external frame structure, the guide cover body is arranged in the external frame structure, one end of the electric telescopic rod is connected to the outer wall of the guide cover, and the other end is installed on the external frame structure; the bottom end of the guide cover body is connected to the external frame structure.

[0016] The present invention provides an external frame structure outside the guide cover body, thereby integrating the guide cover body and the electric telescopic rod into a whole without affecting the fixing and limiting functions of the guide cover body.

[0017] In a specific embodiment, the lower half of the guide cover body is divided into a plurality of guide cover petals separated from each other along the circumferential direction, and each guide cover petal is respectively connected to an electric telescopic rod.

[0018] In a specific embodiment, the guide cover body is divided into four guide cover petals, and the end of the electric telescopic rod is connected and fixed to the center of the guide cover petals.

[0019] Since the thickness of the poles in the upper and lower length directions is uneven, the guide cover needs to be fixed on columns of different sizes during the installation process. In order to solve the above problem, the present invention designs the lower half of the guide cover into multiple guide cover petals with a petal-like structure, and each guide cover petal corresponds to an electric telescopic rod. Therefore, when working, each guide cover petal moves toward the inside of the guide cover and tightens, thereby fixing columns of different sizes by opening and closing the multiple guide cover petals.

[0020] In a specific embodiment, the electric telescopic rod and the external frame structure, the guide cover and the external frame structure, and the electric telescopic rod and the guide cover are all rotatably connected via hinges.

[0021] The present invention has 12 hinges in total, 4 of which are installed at the connection between the electric telescopic rod and the external frame structure, 4 are installed at the connection between the electric telescopic rod and the guide cover body, and play the role of fixing the electric telescopic rod and rotating the end, and the last 4 are installed at the connection between the bottom of the guide cover body and the external frame structure, and play the role of fixing the guide cover body and rotating the lower half of the guide cover body when opening and closing.

[0022] The present invention arranges a hinge, and at the beginning or end of the installation work, the front end of the electric telescopic rod is retracted (usually can be set between 60°-120°) by the hinge under the action of remote control, thereby driving the guide cover flap to close or open, so that it is gradually clamped to the pole until it is fixed or gradually loosened until it is detached.

[0023] In a specific embodiment, a cross arm gap is provided between two adjacent guide cover petals.

[0024] In the present invention, a complete wall is originally enclosed between the guide cover petals. In order to allow the guide cover body to be completely withdrawn after the cross arm is installed, the part that would be blocked by the guide cover petals is removed to form a cross arm gap, which can ensure that the guide cover body is completely withdrawn without affecting all the forces during work, thereby not affecting its fastening and limiting functions.

[0025] In a specific embodiment, the external frame structure is a cubic structure, the end of the electric telescopic rod is installed on the top edge of the external frame structure, and the lower end of the guide cover flap is installed on the bottom edge of the external frame structure. At the same time, the cross arm notch faces the edge of the cubic structure, and the guide cover flap faces the side of the cubic structure, so that there is more space for the cross arm to withdraw after the guide cover body is contracted. The specific implementation is: before the guide cover device works, the cross arm is placed horizontally. When it reaches the top of the pole, the device begins to descend until it stops at 1 / 5 of the distance from the top of the pole, and then the cross arm is installed, and the telescopic rod starts to move. The positive pressure of the top of the guide cover on the pole will produce uniform friction, thereby limiting the guide cover. After the cross arm is installed on the pole, the device will rise along the specified path under the control of the intelligent program, thereby withdrawing the device.

[0026] In a specific embodiment, the guide cover is made of glass fiber composite material, which has good tensile strength and bending strength, thereby ensuring that the guide cover will not be deformed during the process of opening and closing inside and outside, and can effectively cope with various other external force impacts.

[0027] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0028] 1. A guiding device for limiting the position of a cross arm of a concrete pole provided in an embodiment of the present invention can enable the guiding cover to be quickly and conveniently put on the pole and fixedly installed by providing a guiding cover with a conical structure having a small upper part and a large lower part and a corresponding driving structure, thereby achieving the limiting and fixing effect on the cross arm;

[0047] The guide cover of the present invention is used for limiting position. When the UAV carrying the guide cover reaches above the pole, the UAV descends so that the guide cover is put on the pole from top to bottom. Since the guide cover adopts a "small at the top and large at the bottom" structure, the guide cover can fall into the pole more conveniently.
