Description

Technical field:

[0002] The utility model relates to a grounding wire device with a padlock. Background technology:

[0004] In recent years, many cases of electric shock and casualties caused by unauthorized removal of ground wires have occurred in power grid operations. Ground wire devices include ground wires, ground wire clamps, ground rods, etc. Ground wires are usually made of copper wire or steel core copper wire, and the cross-sectional area is generally 16 square millimeters or more. The ground wire clamp is used to connect the ground wire to the ground rod, and is usually made of copper or aluminum alloy. The ground rod is usually made of steel pipe or copper pipe, and the length is generally 1.5 meters or more.

[0005] According to the safety manual, after the operation and maintenance personnel have finished the operation and hung the grounding wire, the maintenance personnel are not allowed to install or remove the grounding wire device without the consent of the operation and maintenance personnel. However, since the grounding wire is usually locked with a five-proof lock at the ground end, the other end can still be disconnected, and the wire clamp and the wire will lose connection; at the same time, the grounding wire clamp is easy to fall off due to the open crimping method, and the connection is not firm, resulting in the loss of protection within the grounding range during operation, causing safety hazards. Utility model content:

[0007] The utility model makes improvements on the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the utility model is to provide a grounding wire device with a padlock, which has a reasonable design and greatly reduces the risk of the grounding wire falling off.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a grounding wire device with a padlock, comprising a horizontally placed U-shaped wire clamp body, a crimping plate arranged inside the wire clamp body and movable vertically, the wire clamp body being connected to a grounding wire, the end of the grounding wire away from the wire clamp body being a grounding end, a positioning groove being arranged at the bottom of the upper side of the wire clamp body, a crimping rod being penetrated through the lower side of the wire clamp body and the crimping plate for vertical sliding, a positioning block for embedding in the positioning groove being arranged at the top of the crimping rod, a pressure-bearing elastic member being connected between the bottom of the positioning block and the top of the crimping plate, and when the positioning block is embedded in the positioning groove, the pressure-bearing elastic member, the crimping plate and the wire clamp body form a closed wire clamping opening.

[0009] Furthermore, a vertically arranged insulating extension tube is fixed to the bottom of the lower side of the wire clamp body, the insulating extension tube corresponds to the position of the positioning groove, the crimping rod slides through the insulating extension tube, and a sliding locking piece is arranged between the crimping rod and the insulating extension tube.

[0010] Furthermore, a limiting hole is provided on the side wall of the lower end of the insulating extension tube, and the limiting hole passes through the insulating extension tube in the radial direction; the sliding locking member includes a spring pin arranged on the side portion of the lower end of the crimping rod and can be extended and retracted in the radial direction of the crimping rod, and the outer end of the spring pin is provided with a locking block that is convenient for the positioning block to be ejected from the limiting hole when the positioning block is embedded in the positioning groove.

[0011] Furthermore, the locking block is provided with a first padlock hole for connecting with a padlock.

[0012] Furthermore, the grounding end of the grounding wire is provided with a second padlock hole for connecting with a padlock.

[0013] Furthermore, the compressed elastic member is deformed and stretched in the vertical direction, and the bottom of the compressed elastic member is fixedly connected to the top of the crimping plate, so that when the positioning block is embedded in the positioning groove, the crimping plate is pulled upward to press the wire.

[0014] Furthermore, the pressure-bearing elastic member is a compression spring, and the compression spring is sleeved on the outside of the crimping rod.

[0015] Furthermore, the diameter of the positioning block is greater than the diameter of the crimping rod.

[0016] Furthermore, a first hand-grip portion is provided on the outer circumference of the lower end of the insulating extension tube; and a second hand-grip portion is provided on the outer circumference of the lower end of the crimping rod.

[0017] Furthermore, the positioning groove is located at one end of the wire clamp body close to the opening.

[0018] Compared with the prior art, the utility model has the following effects: the utility model is reasonably designed, and a closed structure is formed at the opening of the grounding wire clamp, which avoids the phenomenon that the grounding wire falls off the grounding wire clamp due to loose crimping during operation; at the same time, a padlock hole matching the padlock is arranged on the locking block, so that the grounding wire cannot be disassembled and assembled by itself in a closed state, thereby realizing the safe management and control of the grounding wire and greatly reducing the operation risk.

Specific implementation method:

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0027] like Figure 1 As shown, the utility model is a grounding wire device with a padlock, comprising a horizontally placed U-shaped wire clamp body 1, a crimping plate 2 arranged inside the wire clamp body 1 and movable vertically, the wire clamp body 1 is connected with a grounding wire 3, and the end of the grounding wire 3 away from the wire clamp body 1 is a grounding terminal 4, and this part of the structure is the same as the existing grounding wire structure, and the specific improvement is that: a positioning groove 5 is arranged at the bottom of the upper side of the wire clamp body 1, and a crimping rod 6 is vertically slidably penetrated through the lower side of the wire clamp body 1 and the crimping plate 2, and a positioning block 7 is arranged on the top of the crimping rod 6, and the positioning block 7 is located above the crimping plate 2, and the positioning block 7 is used to be embedded in the positioning groove 5, and a pressure-bearing elastic member 8 is connected between the bottom of the positioning block 7 and the top of the crimping plate 2. When the positioning block 7 is embedded in the positioning groove 5, the pressure-bearing elastic member 8, the crimping plate 2 and the wire clamp body 1 form a closed wire clamping opening 9, and the pressure-bearing elastic member 8 uses elastic force to pull the crimping plate 2 upward to press the wire. By forming a closed structure at the opening of the grounding wire clamp, the grounding wire is prevented from falling off the grounding wire clamp due to unreliable crimping during operation.

[0028] In this embodiment, a vertically arranged insulating extension tube 10 is fixed to the bottom of the lower side of the wire clamp body 1, and the insulating extension tube 10 corresponds to the position of the positioning groove 5. The crimping rod 6 slides through the insulating extension tube 10, and the crimping rod 6 can slide up and down in the insulating extension tube 10. The crimping rod 6 drives the positioning block 7 to move synchronously. A sliding locking piece is arranged between the crimping rod 6 and the insulating extension tube 10, and the sliding locking piece is used to lock the crimping rod when the positioning block is embedded in the positioning groove.

[0029] In this embodiment, a limiting hole 11 is provided on the side wall of the lower end of the insulating extension tube 10, and the limiting hole 11 penetrates the insulating extension tube 10 in the radial direction; the sliding locking member includes a spring pin 12 which is arranged on the side of the lower end of the crimping rod 6 and can be extended and retracted in the radial direction of the crimping rod, and a locking block 13 is provided on the outer end of the spring pin 12. When the positioning block 7 is embedded in the positioning groove 5, the locking block 13 is pushed out from the limiting hole 11, so that the crimping rod 6 cannot slide up and down, and the positioning block 7 is kept firmly embedded in the positioning groove 5, ensuring that the wire clamping port is always in a closed state.

[0030] In this embodiment, the locking block 13 is provided with a first padlock hole 14 for connecting with a padlock. When the crimping rod 6 moves upward to the positioning block 7 embedded in the positioning groove 6, the locking block 13 is pushed out from the limiting hole 11, and then the padlock is connected to the first padlock hole to realize padlocking.

[0031] In this embodiment, the grounding end 4 of the grounding wire 3 is provided with a second padlock hole 15, and the second padlock hole is used to connect with a padlock to achieve padlocking.

[0032] The grounding wire device with padlock has two padlocks, one is the grounding terminal 4, and the other is the padlock of the crimping rod 6. After the two ends are padlocked, the disassembly and assembly of the grounding wire can be controlled to prevent maintenance personnel from installing and disassembling the grounding wire without permission, thereby greatly improving safety.

[0033] In this embodiment, the pressure-bearing elastic member 8 is telescopically deformed in the vertical direction, and the bottom of the pressure-bearing elastic member 8 is fixedly connected to the top of the crimping plate 2, so that when the positioning block is embedded in the positioning groove, the crimping plate is pulled upward to press the wire.

[0034] In this embodiment, the pressure-bearing elastic member 8 is a compression spring, and the compression spring is sleeved on the outer side of the compression rod.

[0035] In this embodiment, the diameter of the positioning block 7 is slightly larger than the diameter of the crimping rod 6. Furthermore, the positioning block can be made of rubber material, so that the positioning block can be tightly embedded in the positioning groove.

[0036] In this embodiment, for the convenience of operation, a first hand grip 16 is provided on the outer circumference of the lower end of the insulating extension tube 10 ; a second hand grip 17 is provided on the outer circumference of the lower end of the crimping rod 6 .

[0037] In this embodiment, the positioning groove 5 is located at one end of the wire clamp body 1 close to the opening.

[0038] Specific implementation process: the operator holds the first grip of the insulating extension tube with one hand and the second grip of the crimping rod with the other hand, then moves the crimping rod upward, and the crimping rod drives the locking block to move synchronously, so that the positioning block at the top of the crimping rod is embedded in the positioning groove. At this time, the locking block is ejected from the limiting hole at the lower end of the insulating extension tube under the action of the spring pin, and then connected to the first padlock hole of the locking block through the five-proof padlock to achieve padlocking, and the operator cannot disassemble and assemble without permission. When disassembly is required, the operator holds the first grip of the insulating extension tube 7 with one hand and the second grip of the crimping rod with the other hand, then moves the crimping rod downward, and the positioning block is separated from the positioning groove under the drive of the crimping rod. The positioning block pushes the crimping plate downward through the pressure-bearing elastic member to loosen the wire, and the locking block is squeezed into the inside of the insulating extension tube; when the crimping rod moves downward into place, the locking block is located below the insulating extension tube and pops out again, realizing the removal of the grounding wire.

[0039] The advantages of the utility model are as follows: a closed structure is designed at the wire clamp, which greatly reduces the risk of the grounding wire falling off, causing personnel to lose grounding protection; secondly, the method of using a spring to pull the crimping plate for crimping can ensure that the crimping is firm. The closed and spring crimping structures cooperate with each other to achieve a reliable connection of the grounding terminal and ensure the safety of the operating personnel. At the same time, in order to prevent personnel from installing and disassembling the grounding wire device without the permission of the operation and maintenance personnel, the grounding wire device is designed with a retractable locking block in the locked state, and has a padlock function, so that the grounding wire cannot be disassembled by itself in the closed state, and the disassembly and assembly are convenient. The padlock of the locking block on the crimping rod and the padlock of the grounding terminal are used to achieve safe management and control of the grounding wire device, which can ensure the safety of the operating personnel, greatly reduce the operating risks, and improve the on-site safety management and control, and it has strong practicality.

[0040] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0041] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0042] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
