Description

Technical Field

[0001] The utility model relates to the technical field of power operation and maintenance auxiliary tools, and in particular to a disassembly and assembly fixture for a grounding wire device and a grounding wire device. Background Art

[0002] In the field of electric power, when workers maintain and inspect high and low voltage overhead lines and high voltage cabinet busbars, they need to ground three sets of wires with grounding wires to ensure the absolute safety of the operators. The existing grounding wire devices are operated by the operator rotating the operating rod of the grounding wire device to shrink the clamping part of the grounding wire device, thereby clamping the high voltage wire. This manual rotation and clamping of the high voltage wire consumes the energy of the workers, makes the workers inconvenient to operate, reduces the workers' work efficiency, and may increase the risk of electric shock to the workers through manual contact.

[0003] An existing grounding wire device includes a driving assembly, a clamp, a hand lever assembly and a remote control device. The driving assembly includes a driving motor and a first transmission rod, and the first transmission rod is arranged at the driving end of the driving motor; the clamp includes a fixed conductor and a movable conductor, and the first transmission rod passes through one end of the fixed conductor and then connects to the movable conductor, and the first transmission rod is threadedly connected to the fixed conductor; wherein, an insulating part is arranged at one end of the hand lever assembly, and the driving assembly is arranged at the other end of the hand lever assembly; and the remote control device is connected to the driving motor signal.

[0004] The driving motor of the grounding wire device is arranged on the first transmission rod. One grounding wire device is required for clamping each high-voltage wire. When working, the staff needs to carry a large number of grounding wire devices, and each grounding wire device is provided with a driving motor, which occupies the resources of multiple driving motors. Utility Model Content

[0005] The first purpose of the utility model is to provide a disassembly and assembly fixture for a grounding wire device which can reduce the use of a driving motor.

[0006] The second object of the utility model is to provide a grounding wire device using the above-mentioned disassembly and assembly fixture for the grounding wire device.

[0007] In order to achieve the above-mentioned first purpose, the utility model provides a disassembly and assembly clamp for a grounding wire device, comprising: a clamp body, a movable block and a clamping device; a locking hole is provided at the bottom of the clamp body, and a fixing portion is provided at one end of the clamp body away from the locking hole, and the fixing portion matches the movable block to form a clamping opening; a first extension portion is provided on the side of the fixing portion, and the first extension portion is provided with a first fixing hole that passes through the upper and lower surfaces of the first extension portion; a second extension portion is provided on the side of the movable block, and the second extension portion is provided with a second fixing hole that passes through the upper and lower surfaces of the second extension portion; the clamping device comprises an eccentric wheel handle, a fixing rod and a fixing mechanism, the first end of the fixing rod is fixed to the wheel axle of the eccentric wheel handle, and the second end of the fixing rod is connected to the fixing mechanism; the fixing rod passes through the first fixing hole and the second fixing hole, and the first extension portion and the second extension portion are fixed between the eccentric wheel handle and the fixing mechanism.

[0008] As can be seen from the above scheme, a locking hole is provided at the bottom of the fixture body of the disassembly and assembly fixture, and the locking hole is used to set the wrench head of the electric wrench in the locking hole. The clamping port of the disassembly and assembly fixture can be provided with a grounding wire clamp. The disassembly and assembly fixture is provided with an eccentric wheel handle, so that the grounding wire clamp can be quickly installed on the disassembly and assembly fixture. At this time, the wrench head of the electric wrench is set in the locking hole, so that the electric wrench can drive the grounding wire device to rotate, thereby reducing the manual rotation operation and improving the work efficiency of the staff. In addition, the electric wrench and the grounding wire clamp are installed through the disassembly and assembly fixture. After a high-voltage line is clamped with the grounding wire clamp, the disassembly and assembly fixture can be quickly disassembled, and the disassembly and assembly fixture can clamp the next grounding wire clamp. In this way, one electric wrench can operate multiple grounding wire clamps, saving the resources of the driving device.

[0009] In a further solution, the clamping device also includes a pad, which is arranged below the eccentric wheel handle and moves on the fixing rod.

[0010] It can be seen from this that the pad can prevent the eccentric wheel handle from directly contacting the first extension part or the second extension part, thereby reducing the wear of the eccentric wheel handle or the first extension part or the second extension part.

[0011] In a further solution, the fixing mechanism is a fixing nut, and the fixing nut is threadedly connected to the fixing rod.

[0012] It can be seen that the first extension portion and the second extension portion are fixed by the fixing nut.

[0013] In a further solution, the eccentric wheel handle also includes a handle body, and the handle body moves along the wheel axle of the eccentric wheel handle.

[0014] It can be seen that the handle body moves along the axle of the eccentric wheel. When the handle body moves, the axle is fixed, and the handle body applies pressure to the gasket, so that the first extension part and the second extension part are compressed, so that the clamping port is compressed.

[0015] In a further solution, the fixed portion is configured in a semicircular arc shape, and the movable block is configured in a semicircular arc shape.

[0016] It can be seen that when the fixed portion and the movable block are matched, a circular clamping opening is formed.

[0017] In order to achieve the above-mentioned second purpose, the grounding wire device provided by the utility model includes an electric wrench, a grounding wire clamp, and also includes the above-mentioned disassembly and assembly clamp for the grounding wire device; the wrench head of the electric wrench passes through the locking hole in the disassembly and assembly clamp; the grounding wire clamp is arranged in the clamping mouth, and the electric wrench drives the grounding wire clamp to rotate; the grounding wire is connected to the grounding wire clamp.

[0018] As can be seen from the above scheme, the electric wrench and the grounding wire clamp are installed by the disassembly and assembly fixture. After a high-voltage line is clamped by the grounding wire clamp, the disassembly and assembly fixture can be quickly disassembled, and the electric wrench is withdrawn from the disassembly and assembly fixture, and the disassembly and assembly fixture can clamp the next grounding wire clamp. In this way, one electric wrench can operate multiple grounding wire clamps, saving resources of the drive device.

[0019] In a further solution, the grounding wire clamp includes a transmission rod, a fixed conductor and a movable conductor. The first end of the transmission rod is provided with a movable conductor, and the second end of the transmission rod is provided in a clamping mouth; the first end of the transmission rod passes through the fixed conductor and is connected to the movable conductor, and the transmission rod is threadedly connected to the fixed conductor.

[0020] It can be seen that by clamping the transmission rod through the clamping opening, the electric wrench drives the transmission rod to rotate, thereby making the movable conductor close to the fixed conductor.

[0021] In a further solution, the movable conductor and the fixed conductor form a high-voltage line clamping portion.

[0022] It can be seen that when the movable conductor and the fixed conductor are close to each other, the high-voltage wire clamping portion becomes smaller, and when the high-voltage wire is set in the high-voltage wire clamping portion, the movable conductor and the fixed conductor can fix the high-voltage wire.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0031] Embodiment of the disassembly and assembly fixture for grounding wire device:

[0032] The utility model discloses a disassembly and assembly fixture for a grounding wire device, which is used to connect an electric wrench and a grounding wire fixture, so that the electric wrench can drive the grounding wire fixture to rotate, thereby enabling the grounding wire fixture to clamp a high-voltage wire.

[0033] See also Figures 1 to 6 The disassembly and assembly fixture 1 includes a fixture body 2 and a clamping device 3, and the disassembly and assembly fixture 1 also includes a movable block 22. A locking hole 211 is provided at the bottom of the fixture body, and a fixing portion 21 is provided at one end of the fixture body 2 away from the locking hole 211. The fixing portion 21 matches with the movable block 22 to form a clamping opening 25. Preferably, since the wrench head of the electric wrench used in this embodiment is square, the locking hole 211 in this embodiment is a square hole of the electric wrench sleeve. The shape of the locking hole 211 is set according to the shape of the wrench head of the electric wrench.

[0034] Preferably, the fixing portion 21 is configured to be in a semicircular arc shape, and the movable block 21 is configured to be in a semicircular arc shape. When the fixing portion and the movable block are matched, a circular clamping opening is formed.

[0035] The side of the fixing portion 21 is provided with a first extension portion 213, and the first extension portion 213 is provided with a first fixing hole 212 penetrating the upper and lower surfaces of the first extension portion 213. Specifically, both sides of the fixing portion 21 are provided with a first extension portion 213, and both first extension portions 213 are provided with a first fixing hole 212 penetrating the upper and lower surfaces of the first extension portion 213.

[0036] The side of the movable block has a second extension part 222, and the second extension part 222 is provided with a second fixing hole 221 penetrating the upper and lower surfaces of the second extension part 222. Specifically, the two sides of the movable block are provided with second extension parts 222, and the two second extension parts 222 are provided with second fixing holes 221 penetrating the upper and lower surfaces of the second extension part 222.

[0037] The clamping device 3 includes an eccentric wheel handle 31, a fixing rod 34 and a fixing mechanism 33. The first end of the fixing rod 34 is fixed to the axle 311 of the eccentric wheel handle 31, and the second end of the fixing rod 34 is connected to the fixing mechanism 33. The fixing rod 34 passes through the first fixing hole 212 and the second fixing hole 221, and the first extension portion 213 and the second extension portion 222 are fixed between the eccentric wheel handle 31 and the fixing mechanism 33. The clamping device 3 also includes a pad 32, which is arranged below the eccentric wheel handle and moves on the fixing rod 34. When the raised portion of the eccentric wheel handle 31 rotates to contact the pad 32, the pad 32 moves downward. Specifically, the fixing rod 34 is a screw rod, and the fixing mechanism 33 is a fixing nut, which is threadedly connected to the screw rod. The eccentric wheel handle 31 also includes a handle body 312, which moves along the axle 311 of the eccentric wheel handle 31.

[0038] When in use, the fixing rod 34 is passed through the first fixing hole 212 and the second fixing hole 221, and then the fixing mechanism 33, i.e., the fixing nut, is used to fix the first extension part 213 and the second extension part 222. At this time, the grounding wire device clamped by the clamping opening 25 has not been completely clamped, and the grounding wire device and the disassembly and assembly fixture 1 will be loose. Therefore, at this time, the staff needs to rotate the raised part in the eccentric wheel handle 31 to the pad 32. At this time, since the raised part in the eccentric wheel handle 31 applies pressure to the first extension part 213 and the second extension part 222, the clamping opening 25 contracts, thereby clamping the grounding wire clamp.

[0039] By providing the disassembly and assembly fixture 1 with an eccentric wheel handle 31, the grounding wire clamp can be quickly installed on the disassembly and assembly fixture 1, and at this time, the wrench head of the electric wrench is set in the locking hole 211, so that the electric wrench can drive the grounding wire clamp to rotate, thereby reducing the operation of manual rotation and increasing the work efficiency of the staff. In addition, by installing the electric wrench and the grounding wire clamp through the disassembly and assembly fixture 1, after a high-voltage line is clamped with the grounding wire clamp, the disassembly and assembly fixture can be quickly disassembled, and the disassembly and assembly fixture can clamp the next grounding wire clamp. In this way, one electric wrench can operate multiple grounding wire clamps, saving the resources of the driving device.

[0040] Grounding wire device embodiment:

[0041] See also Figure 7 The wrench head of the electric wrench 4 passes through the locking hole 211 in the disassembly and assembly fixture 1; the grounding wire fixture 5 is arranged in the clamping opening 25, and the electric wrench 4 drives the grounding wire fixture 5 to rotate; the grounding wire ( Figure 7 (not shown) is connected to the grounding clamp.

[0042] The grounding wire clamp 5 includes a transmission rod 53, a fixed conductor 51 and a movable conductor 52. The first end of the transmission rod 53 is provided with the movable conductor 52, and the second end of the transmission rod 53 is provided in the clamping opening 25. The first end of the transmission rod 25 passes through the fixed conductor 51 and is connected to the movable conductor 52, and the transmission rod 53 is threadedly connected to the fixed conductor 51. The movable conductor 52 and the fixed conductor 51 form a high-voltage wire clamping portion 54. Further, the grounding wire is connected to the fixed conductor 51.

[0043] The transmission rod 53 is clamped by the clamping opening 52, so that the electric wrench 4 drives the transmission rod 53 to rotate, thereby making the movable conductor 52 approach the fixed conductor 51. When the movable conductor 52 and the fixed conductor 51 approach each other, the space of the high-voltage wire clamping part 54 becomes smaller, and when the high-voltage wire is set in the high-voltage wire clamping part 54, the movable conductor 52 and the fixed conductor 51 can fix the high-voltage wire.

[0044] By providing the disassembly and assembly fixture 1 with an eccentric wheel handle 31, the grounding wire clamp 5 can be quickly installed on the disassembly and assembly fixture 1, and at this time, the wrench head of the electric wrench 4 is set in the locking hole 211, so that the electric wrench 4 can drive the grounding wire clamp 5 to rotate, thereby reducing the operation of manual rotation and increasing the work efficiency of the staff. In addition, the electric wrench 4 and the grounding wire clamp 5 are installed through the disassembly and assembly fixture 1. After a high-voltage line is clamped with the grounding wire clamp 5, the disassembly and assembly fixture 1 can be quickly disassembled, and the disassembly and assembly fixture 1 can clamp the next grounding wire clamp 5. In this way, one electric wrench 4 can operate multiple grounding wire clamps 5, saving electric wrench resources.

[0045] The above are only preferred embodiments of the present invention, but the design concept of the present invention is not limited thereto. Without departing from the concept of the present invention, more other equivalent embodiments may be included. It is possible for those skilled in the art to make various obvious changes, readjustments and substitutions without departing from the protection scope of the present invention.
