Description

Technical Field

[0001] The utility model relates to the technical field of line warning devices, in particular to an overhead wire quick-install warning mark auxiliary pendant. Background Art

[0002] When overhead transmission lines cross roads or construction sites, they are easily accidentally hit by large vehicles or construction machinery, causing power outages or personal injury accidents. In order to prevent overhead transmission lines from being accidentally hit, warning signs are usually installed on overhead transmission lines. Warning signs are usually light or reflective warnings. There are generally two ways to install existing overhead line warning signs or warning devices. One is to shut down the line and directly fix the wire clamp of the warning device to the overhead line with bolts. This method requires planned power outages, affects normal power supply, has a long installation cycle, slow popularization, and is inconvenient to disassemble and replace; the other is to use live installation, one person uses an operating lever to lift the warning device, and one person uses another operating lever to operate the fixing bolts or hooks of the warning device. The two people work together to complete the installation. Coordination is difficult, the installation time is long, and the risk factor is high.

[0003] A Chinese utility model patent with authorization announcement number CN204833539U discloses a wire clamp assembly and a line protection warning device using the wire clamp assembly. The wire clamp assembly includes a mounting frame, which includes a hook part and a support plate part. The opening of the hook part faces downward and is used to hook on the line. A clamping body is floatingly installed on the support plate part, and an elastic member is top-mounted between the clamping body and the support plate part. The elastic member provides a clamping force to the clamping body toward the hook part to clamp the line. The shaft of the clamping body passes downward through the support plate part and the downward passing part forms a stop fit with the support plate part to prevent the shaft from falling out upward. A slot for cooperating with an operating tool is provided at the lower end of the shaft. The wire clamp assembly requires the use of a special tool when in use. The special tool has a top support part for cooperating with the top support of the support plate part and a pull-down part for cooperating with the card slot to pull the clamping body downward. When the wire clamp assembly needs to be installed on the line, the top support part of the special tool is pressed against the support plate part, and the pull-down part of the special tool cooperates with the card slot to pull the clamping body down to make way for the opening of the hook part. When the line enters the hook part, the clamping body is released, and the clamping body will be pressed upward on the inner wall of the hook part under the action of the elastic member to clamp the line.

[0004] The wire clamp assembly of the existing line protection warning device needs to be used with the help of a special tool, so that the top supporting part of the special tool can support the support plate part of the wire clamp assembly, and at the same time, the pull-down part of the special tool can cooperate with the slot on the clamping body of the wire clamp assembly to pull down the clamping body. This requires the worker to hold the special tool with one hand, so that the top supporting part of the special tool can keep supporting the support plate part of the wire clamp assembly in the air, and at the same time, use the other hand to operate the pull-down part to pull down the clamping body relative to the support plate part, which is very inconvenient to operate.

DETAILED DESCRIPTION

[0024] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0025] The utility model of the auxiliary pendant for quick-installed warning signs for overhead wires is mainly used to solve the problem of inconvenient operation of the wire clamp assembly of the existing line protection warning device when it is used. The basic scheme principle of the utility model of the auxiliary pendant for quick-installed warning signs for overhead wires is as follows: the auxiliary pendant for quick-installed warning signs for overhead wires (hereinafter referred to as the auxiliary pendant) includes a mounting seat, and an elastic floating part floating in the up and down directions is mounted on the mounting seat to prevent it from falling off upward. The elastic floating part is provided with a receiving groove for accommodating the wire and an elastic stopper for blocking the wire in the receiving groove. The mounting seat is provided with a stopper for stopping the elastic stopper and keeping the elastic stopper in a state of clearing the notch of the receiving groove. The mounting seat has a socket connection part for providing an operating rod socket. When the auxiliary hanger needs to be installed on the overhead wire, the elastic stopper is opened so that the stopper stops the elastic stopper and keeps the elastic stopper in a state of clearing the slot, the operating rod is inserted into the socket connection part of the mounting seat, the auxiliary hanger is lifted to the bottom of the wire, the slot is aligned with the wire and pushed upward, and the elastic floating part moves downward relative to the mounting seat, thereby releasing the stopper from blocking the elastic stopper, and the elastic stopper flips to a line blocking state to prevent the wire from falling out of the slot, and then the operating rod is withdrawn; when the auxiliary hanger needs to be removed from the overhead wire, the operating rod is inserted into the socket connection part of the mounting seat, and the auxiliary hanger is pulled downward, the elastic stopper flips open under the action of the pulling force, and the wire falls out of the slot. Conventional insulating operating rods can be used for installation and removal, and no special tools are required. When installing, only the auxiliary hanger needs to be aligned with the overhead wire and pushed upward, and when removing, only the auxiliary hanger needs to be pulled downward, which is very convenient to operate.

[0026] Based on the principle of the above scheme, the following is a detailed introduction to the embodiment of the utility model overhead wire quick-install warning sign auxiliary pendant:

[0027] like Figure 1-5As shown, the overhead wire quick-install warning sign auxiliary pendant includes a mounting seat 9, and a vertically extending plug hole 12 with an opening facing downward is provided at the middle position of the bottom of the mounting seat 9, and the plug hole 12 constitutes a plug socket connection part for the operating rod plug socket. The mounting seat 9 is provided with an elastic floating member floating in the up-down direction, and the elastic floating member is assembled on the mounting seat 9 to prevent upward disengagement, and the elastic floating member is provided with a receiving groove 301 for accommodating the wire 16 and an elastic stopper 2 for blocking the wire 16 in the receiving groove 301. The mounting seat 9 is provided with a stopper, which is a stopper hook 1, which extends from the side of the elastic floating member to the upper side of the elastic floating member, and the stopper hook 1 stops the elastic stopper 2 through the hook head of the upper inner hook so that the elastic stopper 2 is kept in a state of leaving the notch of the receiving groove 301. When the elastic floating member moves downward relative to the mounting seat 9, the stopper hook 1 releases the stopper of the elastic stopper 2, and the elastic stopper 2 flips to the line blocking state to prevent the wire 16 from escaping from the receiving groove 301. The retaining hook 1 extends upward from the side of the elastic floating member to the upper side of the elastic floating member, and can form a flared structure above the elastic floating member to prevent the retaining hook 1 from blocking the elastic floating member, thereby facilitating the wire 16 to smoothly enter the accommodating groove 301.

[0028] There are two elastic stoppers 2, such as Figure 1 As shown, two elastic stoppers 2 are respectively arranged on both sides of the axis of the receiving groove 301, and two stop hooks 1 are provided and correspond to the elastic stoppers 2 one by one. The two elastic stoppers 2 simultaneously stop the wire 16 from both sides of the axis of the receiving groove 301, and the wire 16 is stopped in the receiving groove 301, which can further improve the reliability of stopping the wire 16 and prevent the wire 16 from slipping out of the receiving groove 301. The two elastic stoppers 2 are symmetrically arranged on both sides of the axis of the receiving groove 301, and one of the elastic stoppers 2 is elastically pressed downward on the other elastic stopper 2 in the blocking state, so that the two elastic stoppers 2 form a cross-closure in the blocking state without leaving any gaps, and the wire 16 is completely blocked in the receiving groove 301, which can further improve the reliability of stopping the wire 16, and then improve the stability of the auxiliary hanger after being installed on the wire 16, and prevent the wire 16 from slipping out and causing the auxiliary hanger to fall from a high altitude.

[0029] like Figure 2-3As shown, the elastic stopper 2 includes a pair of torsion springs 202 arranged on both sides of the receiving groove 301, and the two torsion springs 202 of the same pair are arranged at intervals in the length direction of the installation groove, and one elastic action end of the two torsion springs 202 of the same pair is pressed against the elastic floating member, and a stopper 201 extending parallel to the axis of the receiving groove 301 is connected between the other elastic action ends of the two torsion springs 202 of the same pair, and there is an avoidance space between the stopper 201 and the torsion spring 202 to avoid the groove wall of the receiving groove 301, so that the stopper 201 does not interfere with the groove wall of the receiving groove 301 during the flipping process. The stopper 201 is made of insulating rubber material, which can increase the friction between the stopper 201 and the wire 16 to prevent sliding. When the blocking bar 201 is opened outward, the torsion spring 202 is deformed, and the blocking bar 201 is blocked by the blocking hook 1 and remains in a state of clearing the notch of the receiving groove 301; when the elastic floating member moves downward relative to the mounting seat 9, the blocking hook 1 releases the blocking of the blocking bar 201, and the blocking bar 201 flips to the wire blocking state under the action of the torsion spring 202. In the wire blocking state, the blocking bar 201 is pressed against the wire 16, thereby pressing the wire 16 against the wire support seat 3, which can better ensure that the installation position of the wire support seat 3 on the wire 16 is fixed and prevent the wire support seat 3 from sliding on the wire 16. Preferably, the length of the blocking bar 201 is greater than the length of the receiving groove 301, and the two ends of the blocking bar 201 in the length direction exceed the receiving groove 301, so that the blocking bar 201 and the wire 16 have a longer pressing fit section, and the pressing of the wire 16 is more reliable.

[0030] like Figure 1 As shown, the mounting seat 9 is provided with a guide cylinder 7 extending up and down, and the elastic floating member is guided and installed in the guide cylinder 7 along the up and down direction. By guiding the up and down movement of the elastic floating member, the elastic floating member can be prevented from tilting, and the elastic floating member and the overhead wire 16 are quickly aligned, so that the overhead wire 16 can quickly enter the receiving groove 301, thereby improving the installation efficiency and making the installation operation more convenient.

[0031] The elastic floating member includes a wire support seat 3 and an elastic member. The accommodating groove 301 is arranged at the top of the wire support seat 3. The wire support seat 3 is made of insulating rubber material and is used to insulate and support the wire 16. The accommodating groove 301 is semicircular, which is convenient for the wire 16 to enter. A guide block 4 is provided at the bottom of the wire support seat 3. The guide block 4 is movably installed in the guide cylinder 7. The elastic member is installed in the guide cylinder 7 and presses upward against the guide block 4. The elastic member is specifically a coil spring 8, which has a simple structure and is easy to install. Of course, the elastic member can also use a disc spring or the like. There are two guide blocks 4 and they are located on opposite sides of the wire support seat 3. The coil spring 8 and the guide cylinder 7 are in one-to-one correspondence with the guide block 4. By guiding the elastic floating member with two sets of guide structures, the stability and balance of the elastic floating member when it moves up and down can be further improved, and the elastic floating member can be prevented from tilting. A horizontally extending limit rod 5 is provided on the guide block 4, and a limit hole 6 extending up and down is provided on the guide cylinder 7. The limit rod 5 is movably inserted in the limit hole 6 so as to prevent the elastic floating member from being disengaged upward on the mounting seat 9. The limiting rod 5 cooperates with the limiting hole 6 to limit the range of the upward and downward movement of the elastic floating member.

[0032] like Figure 2 As shown in the figure, the middle of the bottom of the mounting seat 9 is provided with a socket 12 with the opening facing downwards, and the auxiliary hanger can be lifted upwards to the overhead wire after the operating rod is inserted into the socket 12. Two pull rings 13 are arranged at the bottom of the mounting seat 9, and the auxiliary hanger can be pulled downwards as a whole by applying force to the pull rings 13, thereby realizing the separation of the auxiliary hanger from the overhead wire.

[0033] like Figure 2-3 As shown, the mounting seat 9 is also provided with a warning sign mounting structure for mounting a warning sign, and the warning sign mounting structure includes a warning light mounting plate 10 and a warning sign mounting plate 11. Two warning light mounting plates 10 are provided and arranged at intervals on the left and right. The warning light mounting plate 10 is provided with a bayonet 14, and a solar warning light can be installed on the warning light mounting plate 10 to play a warning role. Two warning sign mounting plates 11 are provided and arranged at intervals on the left and right. The warning sign mounting plate 11 is provided with bolt fixing holes 15, and the warning sign can be fixed to the warning sign mounting plate 11 by bolts. Warning signs such as warning slogans and reflective films can be set on the warning sign.

[0034] During installation, if Figure 4As shown, first install the solar warning light on the warning light mounting plate 10, then fix the warning sign on the warning sign mounting plate 11, then break open the elastic stopper 2, and use the stop hook 1 to stop the elastic stopper 2 so that the elastic stopper 2 remains in the state of clearing the slot 301, use the operating rod of the corresponding voltage level to insert into the socket 12 of the mounting seat 9, lift the auxiliary hanger to the bottom of the conductor 16, and then push the accommodating slot 301 upward to align the overhead conductor 16, the coil spring 8 is further compressed, and the elastic floating part moves downward relative to the mounting seat 9, thereby moving the elastic stopper 2 downward, and the stop hook 1 releases the stop on the elastic stopper 2, and the elastic stopper 2 flips to the line blocking state to prevent the conductor 16 from escaping from the accommodating slot 301. After withdrawing the operating rod, under the action of the coil spring 8, the elastic floating part moves upward until the limit rod 5 and the top hole wall of the limit hole 6 form a stop, completing the return action, as shown in FIG. Figure 5 As shown, the auxiliary hanger is installed on the wire 16.

[0035] If the solar warning light is damaged or the warning sign is broken during use and needs to be replaced, insert the operating rod into the socket 12 of the mounting base 9, hook the pull ring 13, and pull it downward. Under the limiting action of the limit rod 5 and the limit hole 6, the elastic stopper 2 flips outward and opens, clearing the notch of the accommodating groove 301, and the overhead wire 16 is removed from the accommodating groove 301. The auxiliary hanger can then be removed from the overhead wire 16 and placed on the ground. After replacing the solar warning light or warning sign, it can continue to be installed and used.

[0036] The utility model of the overhead wire quick-install warning sign auxiliary pendant only requires one person to use an operating lever of the corresponding voltage level to complete the installation and removal, and can realize the quick connection, fixation and removal of the auxiliary pendant and the live overhead wire, avoiding the loss caused by power outage to users, and also avoiding the unfavorable factors of high difficulty, long time and high risk of coordination between two people. Through the design of the warning sign installation structure, solar warning lights, warning slogans, reminder signs and reflective films can be replaced conveniently and quickly, and it also avoids the unfavorable factors that there are only warning lights but no reminder signs (such as "Electricity Danger", "Live Line Height 7 Meters") in the past, and the power supply department still bears responsibility after an accident.
