Technical Field

[0001] The present application belongs to the technical field of cable fixing devices, and specifically relates to a 10KV live working lead fixing device. Background Art

[0002] In live distribution network operations, it is common to remove the lead wires, replace the fuses, disconnectors, and pole switches, and then connect the lead wires. The lead wires cannot be effectively fixed after removal, and are often tied with binding tape or temporarily hung directly on the same conductor. It is also easy to fall from a height when holding the lead wire with one hand or inserting a wire clamp. Some existing lead fixing devices easily increase the range of motion of the operator, and cannot adjust the distance between the two ends of the wire, and are still prone to secondary discharge. Therefore, it is necessary to avoid the defects of similar tools already on the market to ensure that live operations are carried out more safely and efficiently. Summary of the invention

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0026] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present application.

[0027] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] The following is a further detailed description of a 10KV live working lead fixing device of the present application in conjunction with the accompanying drawings, but it is not intended to limit the present application.

[0029] A 10KV live working lead fixing device mainly includes a locking device and a monitoring device. Figure 1 As shown, the locking device is composed of a main line fixed end 01, a lead wire fixed end 03 and a telescopic connecting chain 02, and the monitoring device is composed of a pressure monitoring sensor and an indicating device.

[0030] Depend on Figure 2 As shown, the main line fixed end 01 includes a fixed clamp 1 and a movable clamp 3. The main frame of the fixed clamp 1 is connected with an movable buckle 2. The movable buckle 2 is made of ABS and is mainly used to prevent the movable clamp from opening suddenly when the electronic control component fails, causing the lead wire to slip and injure the operator.

[0031] The main material of the anti-skid silicone 5 is silicone, which is attached to the inner side of the arc surface of the main frame of the fixing clamp 1. Its main function is to increase the friction between the main frame and the main line and the lead wire to prevent the main line and the lead wire from sliding and being loosely fixed. The main frame is made of ABS, which is the load-bearing part of the wire and is connected to the telescopic connecting chain. It is formed by a semicircular arc surface and a horizontal plate. The inside of the arc surface is connected to the anti-skid silicone. At the same time, a pressure sensor of the monitoring device is provided inside.

[0032] The movable clamp 3 is mainly composed of a movable buckle and a locker 4. The movable buckle is mainly in a semicircular shape and is connected to one end of the arc surface of the fixed clamp 1 through a hinge. The arc diameter of the movable buckle is slightly larger than the arc surface of the fixed clamp 1. The inner side of the movable buckle is also provided with anti-slip silicone 5, which mainly plays an anti-slip role. The outer side is provided with a buckle track, which is used in conjunction with the movable buckle 2 to achieve the fastening of the wire.

[0033] The locker 4 is mainly composed of a threaded column and a motor, which receives instructions from the pressure sensor. When the pressure sensor detects that the pressure reaches a preset value, the motor starts working, driving the threaded column to rotate and screw into the threaded hole of the fixing clamp. After the pressure sensor detects the next preset value, the motor stops working. At the same time, the motor has a self-locking function to effectively prevent loosening.

[0034] The telescopic connecting chain 02 is mainly composed of a storage box 7 and a connecting chain 6. The storage box 7 is located in the middle and is responsible for the contraction of the connecting chain 6. The interior is mainly composed of a coil spring and a locking structure, and the length can be adjusted according to the different needs of the operator. After adjusting to the appropriate length, the locking structure 8 locks the coil spring to prevent rotation and fix the connecting chain 6. The connecting chain 6 is mainly made of ABS and connects the main line fixed end 01 and the lead fixed end 03.

[0035] The structure of the lead wire fixing end 03 is the same as that of the main wire fixing end 01 , and the two connection chains 6 passing through the storage box 7 are fixedly connected to the lead wire fixing end 03 and the fixing clip 1 of the main wire fixing end 01 respectively.

[0036] When the device is used, keep both fixed ends in the open state at the same time. First, fit the main frame of the main line fixed end 01 to the main line, swing the movable clamp 3 to rotate around the hinge, and tighten the main line under the action of the fixed buckle. After the pressure sensor detects that the pressure has reached the preset value, it will prompt the staff through the prompt light, and the staff can stop the tightening action. Then the locker 4 will automatically lock the movable clamp 3 and the fixed clamp 1. After reaching the preset pressure value, the locking action will stop, and the main line end will be fixed. The prompt light remains on to remind the operator that it is fixed securely. Then the operator pulls the telescopic connecting chain 6 to the appropriate length, and then the lead is fixed securely by the same operation. After it is fixed securely, the connecting chain is retracted through the storage box of the telescopic connecting chain. After it is retracted to the appropriate length, the locking structure is pressed to prevent loosening, and the lead fixing operation is completed.

[0037] The implementation methods of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
