[0001] The present invention relates to the field of high-altitude operation tools for power lines, and particularly to a high-altitude wire connecting pliers. Background Art

[0002] Currently, when conducting power equipment tests, since the equipment points are at high places, an insulating rod hook is usually used to hook the wire to the bolt or bolt hole of the equipment, and the test is carried out suspended in the air.

Detailed Embodiment

[0035] The following will describe the embodiments of the present disclosure in detail with reference to the drawings.

[0036] The following describes the embodiments of the present disclosure through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts belong to the scope of protection of the present disclosure.

[0037] Embodiment 1

[0038] As Figure 1 shown, there is a high-altitude wire connection pliers, including:

[0039] A pair of plier head parts 1, which can be automatically engaged or separated, so as to be able to clamp or loosen the switch wiring board or wire during high-altitude wiring;

[0040] An insulating rod 3, which is used to prevent the operator from getting an electric shock;

[0041] A separation and positioning device 2, which is installed at the bottom of the plier head part 1, and the bottom end is fixedly installed with the insulating rod 3, and is used to drive the plier head part 1 to engage or separate under the operation of the insulating rod 3, so that the operator can stand below and drive the plier head part 1 to engage or separate by driving the separation and positioning device 2 through the insulating rod 3, and the wiring of high-altitude operation can be realized below. At the same time, the separation and positioning device 2 includes a positioning mechanism and a separation mechanism. The positioning mechanism is fixedly connected with the plier head part 1, and the separation mechanism is fixedly connected with the insulating rod 3. The positioning mechanism and the separation mechanism can be positioned and clamped together or separated. During high-altitude operation, after the plier head part 1 clamps the wire board, the positioning mechanism and the separation mechanism are separated, and the separation mechanism and the insulating rod 3 can continue to install the plier head part 1 on another phase wire, so that one insulating rod 3 can be used to install the three plier head parts 1 on the wiring boards of three phases respectively. At the same time, the insulating rod 3 can be made of a lighter material such as hard plastic, making the wiring operation process simpler and effectively improving work efficiency.

[0042] In the existing technology, to achieve the effect of automatically engaging or separating the plier head part 1 at a long distance at high altitude, the commonly used and easily conceivable technical means are generally:

[0043] 1. Hinge the upper plier head 11 and the lower plier head 12 in the middle, and then drive one end of the hinge point to close or separate through a structure to achieve the engagement or separation of the other end. However, this mechanism needs to maintain the force output at the operation end to maintain the engaged state, and the mechanism is complex, easy to be damaged and has poor reliability.

[0044] 2. The upper jaw 11 and the lower jaw 12 are driven to engage or disengage by means of a cylinder pushing, but this method requires installing a cylinder on the jaw member 1, which is heavy and difficult for the operator to lift. Moreover, it also needs to cooperate with components such as a compressor and an air pipe. The whole mechanism is huge and inconvenient to operate and carry.

[0045] 3. Or the upper jaw 11 and the lower jaw 12 are driven to engage or disengage by means of a motor drive. This method also has the defect that it is heavy and difficult for the operator to lift.

[0046] After long-term design analysis and exploration by the applicant, the jaw member 1 of this application includes:

[0047] An upper jaw 11;

[0048] An upper jaw rod 14, the top of which is installed at the bottom of the upper jaw 11, and a pin 18 is provided at the bottom thereof;

[0049] A lower jaw 12, on which a first through hole is provided;

[0050] A lower jaw rod 15, a second through hole is provided in the center thereof, the top of which is installed at the position corresponding to the first through hole at the bottom of the lower jaw 12, and the bottom end thereof is installed at the top of the separation and positioning device 2; a through groove 17 communicating with the second through hole is provided on the lower jaw rod 15, and a plurality of pin positioning openings 16 are opened beside the through groove 17 for clamping the pin 18; the upper jaw rod 14 passes through the first through hole and is inserted into the second through hole, and the pin 18 slides up and down in the through groove 17 or enters the pin positioning openings 16 on both sides; when the pin 18 slides up and down in the through groove 17, it corresponds to the engagement or disengagement of the upper jaw 11 and the lower jaw 12; when it is necessary to fix the positions of the upper jaw 11 and the lower jaw 12, the pin 18 is clamped into the corresponding pin positioning opening 16;

[0051] A return spring 13, which is installed in the second through hole and sleeved on the upper jaw rod 14, and the return spring 13 is located at the part of the upper jaw rod 14 above the pin 18; when the upper jaw 11 and the lower jaw 12 are separated, the return spring 13 is in a highly compressed state to provide the elastic force for resetting after the upper jaw 11 and the lower jaw 12 are separated. When the upper jaw 11 and the lower jaw 12 are in the engaged state, the return spring 13 is in a compressed state to maintain the engagement pressure between the upper jaw and the lower jaw 12.

[0052] The structure of the jaw member 1 for realizing automatic engagement or disengagement is simple and effective, making the operation simple and convenient and the performance reliable.

[0053] In a specific implementation, the separation and positioning device 2 includes:

[0054] A positioning mechanism, the top of which is connected to the bottom end of the lower clamping rod 15;

[0055] A separating mechanism, the upper part of which is connected to the positioning mechanism and the bottom part of which is connected to the insulating rod 3;

[0056] The separating and positioning device 2 enables an operator to make the positioning mechanism and the separating mechanism enter a connection state that is fixed and not easily separable or a connection state that can be easily separated according to operation requirements; in this embodiment, the easily separable connection state means that when the entire aerial wire clamp is lifted by the insulating rod 3, the positioning mechanism and the separating mechanism are not separated, and after the clamp head part 1 is engaged, pulling down the insulating part can separate the positioning mechanism and the separating mechanism; in this embodiment, the not easily separable connection state means that without additional manual operation, lifting or pulling down the insulating part cannot separate the positioning mechanism and the separating mechanism; these two functions enable the separating and positioning device 2 to meet the requirements of various operation scenarios as needed.

[0057] In the general prior art, to achieve such a function or effect, the common means or easily conceivable solutions are to adopt electric control or pneumatic control to achieve changing the control state as needed. However, these two types of control structures require adding motors or cylinders, with complex and large mechanisms, heavy weight, difficult lifting, high labor intensity, and difficult operation.

[0058] In specific implementation, the positioning mechanism adopted in this embodiment includes:

[0059] A rotary joint 21, the top of which is connected to the bottom end of the lower clamping rod 15, and a first cavity is provided inside it, and a block return spring 25 is provided in the first cavity;

[0060] A pin sleeve 28, an insertion hole is provided inside it, and a positioning pin 22 is radially inserted into the insertion hole on each of the two outer sides of it for inserting into the following plug rod 24 to clamp and position the plug rod 24 so that the plug rod 24 cannot slide up and down freely; a positioning pin stop block 26 is also provided in the insertion hole for blocking the positioning pin 22 from entering the insertion hole as needed; the positioning pin stop block 26 is connected to the block return spring 25, so that after the positioning pin 22 is manually pulled out, the block return spring 25 pushes the positioning pin stop block 26 to slide towards the fixed position to block the positioning pin 22 from entering the insertion hole.

[0061] In specific implementation, a pin hole corresponding to the positioning pin 22 is provided on each of the two outer sides of the pin sleeve 28, a positioning pin return spring 27 is provided in the pin hole, the positioning pin 22 passes through the positioning pin return spring 27 and enters the insertion hole, and the positioning pin return spring 27 is used to keep a pressure for the positioning pin 22 to enter the insertion hole, and after the positioning pin 22 is manually pulled out, a return elastic force for the positioning pin 22 to enter the insertion hole is generated.

[0062] A connecting plate is provided between the adapter 21 and the pin sleeve 28 to facilitate assembly, disassembly, and maintenance.

[0063] In a specific implementation, the separation mechanism includes:

[0064] A plurality of positioning beads 23 located within the jack;

[0065] A plug rod 24 having positioning holes at its top corresponding to the sizes of the positioning beads 23 and the positioning pin 22. The top of the plug rod 24 can be detachably inserted into the jack, and its bottom end is connected to the insulating rod 3.

[0066] When it is required that the positioning mechanism and the separation mechanism are in a state where they cannot be easily separated, insert the plug rod 24 into the jack and push the positioning pin stopper 26 upwards, so that the positioning pin 22 enters the positioning hole. In this way, as long as the positioning pin 22 is not manually pulled out, the positioning mechanism and the separation mechanism are in a state where they cannot be easily separated; when it is required that the positioning mechanism and the separation mechanism are in a state where they can be easily separated, only need to pull out the positioning pin 22, so that the stopper return spring 25 pushes the positioning pin stopper 26 to slide downwards to block the positioning pin 22 from entering the jack. At the same time, the positioning beads 23 enter the positioning holes of the plug rod 24. In this way, when only pulling down the separation mechanism, it can be separated from the positioning mechanism. However, due to the positioning effect of the positioning beads 23, the separation mechanism will not fall off randomly when not pulled, achieving the effect of being able to control positioning or separation according to needs, with a simple structure, easy to operate, and reliable performance.

[0067] In a specific implementation, the plug rod 24 and the insulating rod 3 are connected through a special joint 29 to facilitate the replacement of the plug rod 24 when it is damaged and facilitate maintenance.

[0068] In a specific implementation, the upper part of the special joint 29 is provided with a plug rod hole, and the bottom is provided with a threaded hole; the bottom of the plug rod 24 is inserted into the plug rod hole; the insulating rod 3 is inserted into the threaded hole.

[0069] In a specific implementation, the upper part of the special joint 29 is provided with a plug rod hole, and the bottom is provided with an insulating rod hole; the bottom of the plug rod 24 is inserted into the plug rod hole; the insulating rod 3 is inserted into the insulating rod hole. Both holes are used to fix the plug rod 24 and the insulating rod 3 from the radial direction with screws.

[0070] In a specific implementation, a coiling rod 4 is further provided on the positioning structure of the high-altitude wire connecting pliers. There is an angle between the coiling rod 4 and the lower plier rod 15, which is in a V shape. A folding rod is further provided at the free end of the coiling rod 4 away from the lower plier rod 15, forming a V shape in a recycling state. The coiling rod 4 is used for winding when the high-altitude line needs to be sorted out, and then swinging the line for sorting or recycling.

[0071] Usage method:

[0072] 1. Separate the upper and lower jaws before use, and rotate the pin 18 of the upper jaw 11 to engage it into the pin positioning port 16;

[0073] 2. Pull out the two side positioning pins 22 by a certain distance. Due to the action of the block return spring 25, the positioning pin block 26 will be pushed downward to reach the limit position, and the positioning pin 22 will be blocked by the positioning pin block 26 and cannot be fully reset, and the positioning pin return spring 27 is in a compressed state;

[0074] 3. The upper end of the insertion rod 24 is provided with a positioning hole and the lower end is fixed on the special joint 29. The special joint 29 is fixed to the insulating rod 3. Slowly insert the insertion rod 24 into the insertion hole of the pin sleeve 28. When a clicking sound is heard, it means that the positioning ball 23 in the insertion hole has been engaged into the positioning hole of the insertion rod 24. At this time, hold the insulating rod 3 and lift the entire high-altitude wire connecting pliers;

[0075] 4. After lifting the entire high-altitude wire connecting pliers to the designated position, rotate the insulating rod 3 to disengage the pin 18 on the upper jaw rod 14 from the pin positioning port 16. The upper and lower jaws will automatically engage under the action of the return spring 13. Pull out the insulating rod 3 downward to achieve the effect of partial separation of the insulating rod 3;

[0076] 5. When it is necessary to remove the high-altitude wire connecting pliers, insert the insertion rod 24 on the insulating rod 3 into the insertion hole of the pin sleeve 28, and push the positioning pin block 26 upward with a certain force to disengage the positioning pin block 26 from the positioning pin 22. The positioning pin 22 is inserted into the designated positioning hole of the insertion rod 24 due to the action of the positioning pin return spring 27. At this time, the insulating rod 3 and the high-altitude wire connecting pliers are engaged and cannot be removed;

[0077] 6. Pull the insulating rod 3 downward to separate the upper and lower jaws, pull the pin 18 to the designated pin positioning port 16 and rotate the insulating rod 3 for positioning, and then the entire high-altitude wire connecting pliers can be removed.

[0078] The present invention relates to the field of high-altitude operation tools for power lines, and provides a high-altitude wiring pliers, comprising: a pliers head member which can be automatically engaged or separated to clamp or loosen a switch wiring board or a wire; an insulating rod which is used to prevent the operator from getting an electric shock; a separation positioning device which is installed at the bottom of the pliers head member and has its bottom end fixedly installed with the insulating rod and is used to drive the pliers head member to be engaged or separated under the operation of the insulating rod. When conducting a wiring test, the present invention clamps a switch wiring board or a wire with the pliers head member, thereby solving the problems that the connection between the test wire and the high-altitude wiring pliers is not firm, resulting in poor contact and easy detachment, which endangers the personal safety of the test personnel. At the same time, after the jaws of the pliers head member to be opened are installed on the switch wiring board and clamped, the insulating rod is separated, and then the jaws of the other phase are installed continuously, so that one insulating rod can be used to install the three jaws on the wiring board respectively. At the same time, a lighter material can be used for the insulating rod, making the wiring operation process simpler and effectively improving the work efficiency.
