Description

Technical Field

[0001] This utility model relates to the field of power maintenance technology, and in particular to the field of maintenance technology of isolating knife switches, specifically a power maintenance safety protection clamp. Background Technology

[0002] As an important piece of electrical equipment, the isolating knife switch, also known as a knife switch or disconnecting switch, is a simple and widely used low-voltage electrical appliance, often used as a power control switch. Its main function is to cut off the power supply when electrical equipment is being maintained, disconnecting the equipment from live parts and maintaining an effective isolation distance to ensure the safety of maintenance personnel.

[0003] Inspecting isolating switches is an indispensable task in power system maintenance. It not only ensures the safe conduct of power system maintenance, prevents equipment failures from escalating, and guarantees the stable operation of the power system, but also extends the service life of equipment and meets the development needs of the power system.

[0004] Currently, the maintenance of isolating switches is mainly done manually. To ensure personal safety, maintenance personnel must wear safety helmets, insulated clothing, insulated boots, and insulated gloves, as well as safety ropes or safety belts. To prevent falls from heights, there are strict requirements for the use of safety ropes; "low-hanging, high-use" is not permitted. That is, one end of the safety rope must not be tied to a low point while the other end is tied to the waist or back of the operator standing at a height performing maintenance work. Therefore, it is necessary to develop a safety clamp. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects and deficiencies of the existing technology and provide a power maintenance safety protection clamp to achieve "high hanging and low use" of the safety rope, which conforms to the specifications of maintenance operations and protects the personal safety of maintenance personnel.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A power maintenance safety clamp includes a channel steel for installing a disconnecting knife switch and a vertical plate disposed on the rear side of the closed end of the channel steel. The vertical plate is characterized by: an upwardly extending vertical rod fixedly connected to the rear side; a hanging lug fixedly connected to the top of the vertical rod for attaching a safety rope; and an upper clamp and a lower clamp respectively provided on the front side of the vertical plate. Both the upper and lower clamps are locked to the upper and lower sides of the channel steel by locking components.

[0008] Furthermore, the upper and lower sides of the upright plate are respectively provided with through grooves that penetrate its front and rear sides.

[0009] Furthermore, both the upper and lower clamps include a C-shaped member with its open end facing the open end of the channel steel, and the closed end of the C-shaped member is provided with a through hole.

[0010] Furthermore, the locking component includes an upper screw, a lower screw, and locking nuts that are respectively screwed onto both ends of the upper screw and the lower screw. The upper screw and the lower screw extend from front to back through the through hole and the through grooves on the upper and lower sides, respectively. The locking nuts at both ends are tightened and abut against the outer side of the closed end of the channel steel and the rear side of the upright plate, respectively. The front side of the upright plate abuts against the outer side of the closed end of the channel steel. The C-shaped components on the upper and lower sides are respectively locked onto the upper and lower sides of the channel steel, forming an interlocking structure.

[0011] Furthermore, the upper through groove is a vertical strip-shaped through groove.

[0012] Furthermore, both the upright and the hanging lug are insulating components.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model utilizes a portion of the existing isolating knife switch mounting bracket, namely the channel steel. A vertical plate is installed on the rear side of the closed end, and an upwardly extending vertical pole is fixedly connected to the rear side of the vertical plate. A hanging lug for attaching a safety rope is fixedly connected to the top of the vertical plate. At the same time, upper and lower clamps are installed on the front side of the vertical plate and locked to the upper and lower sides of the channel steel by locking components. This provides stable and reliable support for the vertical pole, realizing the "high hanging and low use" of the safety rope, which conforms to the specifications of maintenance operations, ensures the personal safety of maintenance personnel, and is convenient to install and securely fixed.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See Figure 1-4 A power maintenance safety clamp includes a channel steel 1 for installing a disconnecting knife switch and a vertical plate 2 set on the rear side of the closed end of the channel steel 1. An upwardly extending vertical rod 3 is fixedly connected to the rear side of the vertical plate 2. A hanging lug 4 is fixedly connected to the top of the vertical rod 3 for attaching a safety rope. An upper clamp and a lower clamp are respectively provided on the front side of the vertical plate 2. The upper clamp and the lower clamp are locked to the upper and lower sides of the channel steel by locking components.

[0021] In this utility model, the upper and lower sides of the upright plate 2 are respectively provided with through grooves 5 that penetrate through its front and rear sides.

[0022] In this utility model, both the upper clamp and the lower clamp include a chamfered part 6 with its open end facing the channel steel 1, and the closed end of the chamfered part 6 is provided with a through hole 7.

[0023] In this utility model, the locking component includes an upper screw 8, a lower screw 9, and locking nuts 10 that are respectively screwed onto the two ends of the upper screw 8 and the lower screw 9. The upper screw 8 and the lower screw 9 extend from front to back through the through hole 7 and the through grooves 5 on the upper and lower sides, respectively. By tightening the locking nuts 10 at both ends, they abut against the outer side of the closed end of the channel steel 1 and the rear side of the upright plate 2, respectively. This allows the front side of the upright plate 2 to abut against the outer side of the closed end of the channel steel 1. The upper and lower C-shaped parts 6 are respectively locked onto the upper and lower sides of the channel steel 1, forming an interlocking structure. That is, the inner wall of the bottom of the upper C-shaped part 6 abuts against the inner wall of the top of the channel steel 1, and the inner wall of the top of the lower C-shaped part 6 abuts against the inner wall of the bottom of the channel steel 1.

[0024] In this invention, the upper through groove 5 is a vertical strip through groove, which can adjust the height of the upper screw 8 to accommodate channel steel with different groove widths.

[0025] In this invention, both the upright pole 3 and the hanging lug 4 are insulating components to ensure safety.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] During installation, first attach the safety protection clamp of this utility model to a part of the mounting bracket of the isolating knife switch, namely the channel steel 1.

[0028] Then, tighten the locking nuts 10 at both ends so that they abut against the outer side of the closed end of the channel steel 1 and the rear side of the upright plate 2, respectively. This allows the front side of the upright plate 2 to abut against the outer side of the closed end of the channel steel 1, and the upper and lower C-shaped parts 6 to lock onto the upper and lower sides of the channel steel 1, forming an interlocking structure. Specifically, the inner wall of the bottom of the upper C-shaped part 6 abuts against the inner wall of the top of the channel steel 1, and the inner wall of the top of the lower C-shaped part 6 abuts against the inner wall of the bottom of the channel steel 1. Thus, the safety protection clamp of this utility model is locked onto the channel steel 1, providing stable and reliable support for the upright 3.

[0029] After installation, maintenance personnel will attach one end of the safety rope around their waist or back to the hanging ear 4, achieving "high hanging and low use" of the safety rope. That is, the safety rope is attached to a "high place" while the maintenance personnel stand at a "low place" to carry out maintenance work. This complies with the specifications of maintenance work and can effectively protect the personal safety of maintenance personnel during the maintenance process.

[0030] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0031] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
