Description

Technical Field

[0001] The utility model belongs to the technical field of pin replenishment installation, and particularly relates to a tool for live installation of locking ring pins on transmission lines. Background Art

[0002] In the connection between the conductors and the poles of overhead transmission lines, pins are widely used in various hardware with bolts to prevent the bolts from falling off and prevent accidents. In actual operation, due to factors such as strong winds, ice and snow weather, and the self-weight of the conductors, the transmission lines will dance, making it inevitable for the pins on the transmission lines to fall off. The falling off of the pins puts the clamp bolts in an unprotected state, and there is a potential safety hazard of transmission line failures such as the falling off of the clamp bolts causing the line to drop during long-term operation. Therefore, it is necessary to use professional installation equipment to install the pins live to maintain normal power supply.

[0003] Currently, for the work of replenishing and installing pins on transmission line clamps, the commonly used method is to first cut off the power supply of the line where the pins need to be replenished and installed, and then the staff can carry out the replenishment and installation. This method has a long construction period, and frequent power outages will reduce the reliability of the power grid operation, affecting people's daily life and production work. Moreover, during the installation process, the installation time is long, and it is easy for the pins to fall off, causing line tripping and even collapse accidents. Therefore, it is necessary for the staff to improve it. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tool for live installation of locking ring pins on transmission lines to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A tool for live installation of locking ring pins on transmission lines, comprising:

[0007] A connecting rod;

[0008] The top of the connecting rod is fixedly connected with a socket frame, and one side of the inner wall of the socket frame is inserted with a spring column;

[0009] The other side of the inner wall of the socket frame is fixedly connected with a right-angled iron rod, and one side of the surface of the right-angled iron rod is inserted into the inner wall of the spring column. The top of the spring column is fixedly connected with an adapter frame, and the middle part of the inner wall of the adapter frame is sleeved on the surface of the right-angled iron rod. One side of the top of the adapter frame is fixedly connected with an installation ring, and one side of the top of the installation ring is fixedly connected with a locking head.

[0010] Preferably, a connection hole is opened on one side of the top of the locking head, and one side of the inner wall of the connection hole is sleeved on the surface of the right-angled iron rod.

[0011] Preferably, an insulating rod is fixedly connected to the bottom end of the connecting rod, and an anti-slip sleeve is fixedly connected to one side of the surface of the insulating rod.

[0012] Preferably, the right-angle end of the right-angle iron rod is arranged at the top of the locking head.

[0013] Preferably, the socket frame and the connection frame have the same size.

[0014] Preferably, the material of the insulating rod is one of wood, fiberglass, and plastic.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] (1) Through the settings of the connecting rod, socket frame, spring column, right-angle iron rod, connection frame, mounting ring, and locking head, during use, pressing the spring column can perform the operation of supplementing pins for the transmission line clamp while being energized. Due to the telescopic deformation of the spring column, a certain position distance is generated between the locking head and the 90° bent part at the top of the built-in right-angle iron rod. The operator places the outer ring part of the pin between the two, restores the deformation of the spring column to firmly clamp the pin on the operating tool. At this time, the 90° bent part at the top of the built-in right-angle iron rod is perpendicular to the outer wall of the locking head in space. The operator reliably inserts the pin into the hole at the tail of the clamp bolt through the operating tool and buckles the outer ring of the pin. Rotate the operating tool by 90° to disengage the pin from the operating tool. At this time, the 90° bent part at the top of the built-in right-angle iron rod is parallel to the outer wall of the locking head in space. The operator retracts the operating tool to complete one-time live installation, thus achieving the effect of convenient live installation of pins and being convenient for the operator to operate.

[0017] (2) Through the setting of the insulating rod, using the insulating operating rod saves the time for installation without power outage. The operation time is shortened to minutes, and then the goal of shortening the operation time from 1 hour to 30 minutes is achieved. In addition, the time required for the operating personnel to cut off the power supply for the line where the pins need to be supplemented can also be saved, thus achieving the effect of live installation of pins and being convenient for the operator to operate.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Embodiment 1:

[0025] Please refer to Figures 1 to 4 As shown in the figure, a tool for installing a locking ring pin on a live transmission line includes:

[0026] Connecting rod 1;

[0027] The top end of the connecting rod 1 is fixedly connected with a socket frame 2. The connecting rod 1 serves as the main support and connection part of the overall tool. One side of the inner wall of the socket frame 2 is inserted with a spring column 3, and the spring column 3 provides a function of telescopic deformation;

[0028] The other side of the inner wall of the socket frame 2 is fixedly connected with a right-angle iron rod 4, and one side of the surface of the right-angle iron rod 4 is inserted into the inner wall of the spring column 3. The top end of the spring column 3 is fixedly connected with a connecting frame 5, and the middle part of the inner wall of the connecting frame 5 is sleeved on the surface of the right-angle iron rod 4, which has a 90° bending part and cooperates with the locking head 7 to form a clamping space. One side of the top of the connecting frame 5 is fixedly connected with a mounting ring 6, one side of the top of the mounting ring 6 is fixedly connected with a locking head 7, a connecting hole is opened on one side of the top of the locking head 7, and one side of the inner wall of the connecting hole is sleeved on the surface of the right-angle iron rod 4. The right-angle end of the right-angle iron rod 4 is arranged at the top of the locking head 7, and the socket frame 2 and the connecting frame 5 have the same size.

[0029] The bottom end of the connecting rod 1 is fixedly connected with an insulating rod 8. One side of the surface of the insulating rod 8 is fixedly connected with an anti-slip sleeve. The material of the insulating rod 8 is one of wood, fiberglass and plastic.

[0030] The wooden insulating rod is mainly composed of wood, resin and adhesive, with low cost and good seismic performance; the fiberglass insulating rod, also known as the glass fiber reinforced plastic (FRP) insulating rod, has excellent properties such as resistance to strong acids and alkalis, high temperature resistance, flame retardancy and smoke resistance, light weight and high strength, corrosion resistance, and aging resistance. It can be processed into different specifications and structural forms and has a wide range of uses. It is especially suitable for environments such as high altitudes and deserts; the common materials of plastic insulating rods include high molecular materials such as polyimide, polystyrene, and polypropylene, which have good insulation performance and anti-ultraviolet performance, are light in weight and corrosion-resistant.

[0031] Working principle: When in use, pressing the spring post 3 can be charged to perform the operation of replenishing the pin for the transmission line clamp. Through the telescopic deformation of the spring post 3, the locking head 7 generates a certain positional distance from the 90° bent part at the top of the built-in right-angle iron rod 4. The staff places the outer ring part of the pin between the two, restores the deformation of the spring post 3, and firmly clamps the pin on the operating tool. At this time, the 90° bent part at the top of the built-in right-angle iron rod 4 is perpendicular to the outer wall of the locking head 7 in space. The operator reliably inserts the pin into the tail hole of the clamp bolt through the operating tool and buckles down the outer ring of the pin, then rotates the operating tool by 90° to separate the pin from the operating tool. At this time, the 90° bent part at the top of the built-in right-angle iron rod 4 is parallel to the outer wall of the locking head 7 in space. The staff retracts the operating tool to complete a live installation. Using the insulating operating rod 8 saves the time of power-off installation, and the operation time is shortened to 30 minutes, thus achieving the goal of shortening the operation time from 1 hour to 30 minutes. In addition, it can also save the time required for the operating personnel to cut off the power supply for the line where the pins need to be replenished.
