[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] like Figure 1-7 As shown, in order to solve the problems of long construction period, difficult installation and removal, and difficult to ensure protection quality and safety of the original protective devices in the prior art, the present invention provides an embodiment: a high-voltage line quick installation and removal protective device, comprising protective rods 1 evenly arranged along the side of the high-voltage line 2 close to the tower crane 6, the protective rods 1 being detachably connected to the fixed foundation 5 located on the ground; a plurality of transverse protective ropes 4, which are horizontally connected to the upper part of the protective rods 1, and the position of the transverse protective ropes 4 is higher than the top of the high-voltage line 2; a reinforcement rope 18, which is obliquely arranged on both sides of the protective rod 1, one end of which is connected to the upper part of the protective rod 1, and the other end is connected to the ground. A protective wall is formed by arranging multiple protective rods 1 in a row and the transverse protective ropes 4, which can prevent the hook of the tower crane 6 from hitting the high-voltage line 2, and the reinforcement rope 18 can improve the installation strength of the protective rod 1. The protective rod 1 is a detachable structure, which can be quickly installed and disassembled.

[0026] Specifically, the protective rod 1 is composed of multiple steel pipes 3 connected up and down. The steel pipe 3 can be a φ150*4mm galvanized steel pipe. The spacing between the protective rods 1 is 30m. The upper part of the protective rod 1 is provided with three first fixing rings 8 along the vertical direction. The horizontal protective rope 4 passes through the corresponding first fixing rings 8. The high-voltage pole of the high-voltage line 2 is generally 14.4m above the ground. The total length of the protective rod 1 is 18m. It is buried 1 meter underground and 17m above the ground. The end of the steel pipe 3 is provided with a fixed steel plate 16. A rubber gasket 15 is provided between the upper and lower fixed steel plates 16 and is connected by multiple fixing bolts 14. The fixed steel plate 16 can quickly connect the upper and lower steel pipes 3. The rubber gasket 15 can play a pre-tightening effect to improve the connection strength of the fixed steel plate 16.

[0027] Specifically, the transverse protection rope 4 and the reinforcement rope 18 are both made of steel wire rope, which has sufficient strength and is easy to obtain.

[0028] Among them, the first fixed ring 8 is provided with a rope pulley 17 for guiding the transverse protection rope 4, which can guide the transverse protection rope 4 and facilitate the transverse protection rope 4 to pass through the first fixed ring 8 quickly. By applying lubricant on the rope pulley 17, the wear of the transverse protection rope 4 can be reduced.

[0029] As a way of installing the reinforcement rope 18, Figure 3 As shown, one end of the reinforcing rope 18 is connected to any one of the first fixing rings 8, and the other end is connected to a second fixing ring 19 on the ground. The first fixing ring 8 and the second fixing ring 19 facilitate quick connection of the reinforcing rope 18, while the second fixing ring 19 is fixed and quickly installed and removed via anchor bolts 9 pre-buried in the ground. Furthermore, a rope tightener 7 is installed on the reinforcing rope 18 to achieve rapid tightening of the reinforcing rope 18.

[0030] In order to make the protective device safer, the outer sides of the protective rod 1, the horizontal protective rope 4, the reinforcement rope 18, the first fixing ring 8 and the second fixing ring 19 are all wrapped with an insulating layer to prevent the protective device from colliding with the high-voltage line and causing conductive accidents. The insulating layer can be made of PVC sleeve or insulating heat shrink tube, and the outer side of the insulating layer is painted with black and yellow fluorescent paint at intervals to form a warning color.

[0031] As a quick-release connection method between the protection rod 1 and the fixed foundation 5, such as Figure 4-5 As shown, the fixed foundation 5 includes a concrete base plate 12 and a sand cylinder 13 arranged on the upper side of the concrete base plate 12. The lower end of the protective rod 1 passes through the sand cylinder 13 and is connected to the concrete base plate 12. The lower part of the protective rod 1 is hollow and the lower side wall of the protective rod 1 is provided with an opening. A movable sand retaining plate 10 is provided at the opening. The sand retaining plate 10 is connected to a force transmission rod 11 extending to the upper side of the sand cylinder 13. The sand retaining plate 10 can be opened from the ground through the force transmission rod 11, so that the sand and gravel in the sand cylinder 13 can enter the cavity of the protective rod 1. The protective rod 1 can be pulled out after being loosened to achieve quick disassembly.

[0032] In addition, the tower crane 6 performs lifting operations within the construction section, an over-limit braking device is installed, and a protective device warning zone is set. Unless safety measures are taken under special circumstances and the project manager approves, the tower crane 6 arm shall not enter the protective device warning zone at will, and strict monitoring and control measures shall be taken.

[0033] The tower crane 6 is provided with a high-voltage electrostatic discharge device and protective facilities, and a 4mm 2The copper core is connected in a ring and reliably grounded (it can be connected to a lightning arrester). The tower crane 6 must have at least two grounding points (it can also be welded to the main reinforcement of the foundation). The grounding resistance is required to be no greater than 1Ω. The tower crane 6 has an insulating sleeve on the hook and is replaced regularly. In addition, the table of the tower crane 6 cab is equipped with a high-voltage insulating pad. All electrical devices are kept well insulated so that they can function properly.

[0034] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being described. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this disclosure, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0036] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0037] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
