Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.
The existing telegraph pole erection needs to use a pile driver or similar equipment such as a ground punching machine to insert the integrally formed telegraph pole into the ground, then an electric wire mounting support is erected on each section of the telegraph pole, meanwhile, the telegraph pole is erected at intervals, electric shock danger caused by the fact that the electric wire is too close to the ground is prevented, and the effect of stabilizing power supply of an electric wire line is achieved.
However, newly-built dwellings or factories need to temporarily introduce electric power to build and produce buildings, so that extra lines need to be temporarily built on the basis of an original power grid to introduce the electric power, the introduced electric power lines are generally low-voltage lines, the erection height operation standard of the low-voltage lines is lower than that of common power grid lines, the lines can pass through other dwellings or factories in the process of erecting the lines to a destination, the land occupation of other people or the land of a factory area is realized when a machine is used for installation, land expropriation or negotiation and negotiation are complicated, deep holes need to be formed in the ground when a hard texture surface is met, the installation progress can be slowed down, and the damaged land section needs to be repaired after a support frame of an electric wire power supply line is removed, so that the cost of the stringing can be increased.
In the first embodiment, as shown in fig. 1, the wire installation member 2 is arranged at a proper height above the ground by utilizing the characteristic of low erection height of the low-voltage line and the detachable connection of the first connecting member 1 and the base 3, and the center of gravity is low due to the low overall height of the power supply line support frame, so that the wire installation member 2 can be lifted to a height which cannot be touched by a worker on the ground by using the detachable connection mode.
Optionally, the base 3 of the power supply line support frame is a thin plate, the larger the area of the thin plate is, the stronger the anti-toppling capability of the power supply line support frame is, the plane on the thin plate is the placing surface 31, the first connecting piece 1 is vertically fixed in the center of the thin plate, articles such as stones and buckets and the like with larger weight can be placed on the placing surface 31 of the first connecting piece 1 to serve as a compression structure to provide weight for the bottom of the power supply line support frame, the gravity center of the whole power supply line support frame is pulled down, the larger the weight of the placed weight is, the closer the gravity center is to the ground, and if the heavy object is caught in a wind and rain day, the heavy object on the surface of the placing surface 31 can provide stability for the power supply line support frame, so that the power supply line support frame is prevented from being turned on one side.
Through above-mentioned stable mode alright in order to forbid using professional equipment to carry out the fixed mode that inserts ground to current wire pole power supply line support frame, the stereoplasm ground that need not destroy other mills or local-style dwelling houses uses, directly put base 3 subaerial directly, and carry out the installation of first connecting piece 1 and wire installed part 2 on base 3, when demolising, directly separate first connecting piece 1, can not leave the great ground hole of diameter subaerial, need not bury the ground hole, thereby the engineering volume of installation low pressure electric wire power supply line support frame installation and demolition has been reduced.
As shown in fig. 2, the wire mounting member 2 includes a movable clamping member 23, a first push rod 21 and a second push rod 22, the movable clamping member 23 is mounted on the first connecting member 1, the movable clamping member 23 can move up and down along the first connecting member 1, the lower end of the first push rod 21 is rotatably connected with the movable clamping member 23, the upper end of the first push rod 21 is rotatably connected with the lower end of the second push rod 22, and the upper end of the second push rod 22 is connected to the top end of the first connecting member 1;
the movable clamping piece 23 drives the second push rod 22 to rotate through the first push rod 21, so that the second push rod 22 rotates around the top end of the first connecting piece 1.
In the stringing field of low pressure circuit, after putting the power supply line support frame, need carry out horizontal or vertical range with many electric wires, need erect horizontal or fore-and-aft wire installing support alone at integrated into one piece's power supply line support frame upper end under the prior art, wire installing support places separately with the power supply line support frame needs occupy more space, uses at every turn and all needs to connect alone, dismantles comparatively difficultly.
