Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of grounding angle steel, and in particular relates to a grounding angle steel that prevents wire derailment. Background Technology
[0002] Grounding angle steel is a device used to fix grounding wires to the ground and conduct the current in the grounding wires to the ground. After the grounding angle steel is buried in the ground, during the use of the grounding wire, the forces of soil settlement, frost heave, and compression will pull or twist the connection point between the grounding wire and the angle steel. Vibrations caused by nearby equipment and traffic will continue to act on the connection point, causing bolts to loosen, metal fatigue, or even breakage, eventually causing the grounding wire to fall off, thus posing a risk of electric shock to the circuit and related electrical equipment.
[0003] To address this issue, we provide a grounding angle steel to prevent wire slippage. Utility Model Content
[0004] The purpose of this utility model is to provide a grounding angle steel to prevent wire derailment. By fixing a tapered steel end cap to the upper opening of the buried tapered steel, and fixing a buffer component to the lower end face of the tapered steel end cap, one end of the grounding wire is connected to the buffer component. The buried tapered steel is buried underground. When tensile stress is generated between the grounding wire and the buffer component, the buffer component will buffer the tensile stress, thereby preventing the grounding wire from being pulled apart and causing derailment. By fixing a sleeve steel cylinder to the upper end of the tapered steel end cap and sleeve the sleeve steel cylinder on the outside of the grounding wire, external force is prevented from damaging the connection between the grounding wire and the buffer component, which would cause the grounding wire to derail.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a grounding angle steel for preventing wire disconnection, including a buried cone steel, a sleeve steel cylinder and a buffer assembly. The buried cone steel has a triangular tube structure, and the lower end of the buried cone steel is pointed. A cone steel end cap is fixedly sleeved at the upper opening of the buried cone steel. The sleeve steel cylinder is fixedly installed on the upper end surface of the cone steel end cap, and the buffer assembly is installed on the lower end surface of the cone steel end cap.
[0006] A further feature of this invention is that the buffer assembly includes a buffer cylinder, a buffer spring, and a pull rod. The lower end of the buffer cylinder is closed, and the upper end of the buffer cylinder is fixedly connected to the lower end face of the tapered steel end cap. The buffer spring is sleeved in the buffer cylinder. A compression spring piston is fixedly provided at the lower end of the pull rod. The compression spring piston is vertically slidably sleeved in the buffer cylinder. The pull rod passes through the tapered steel end cap and extends into the sleeved steel cylinder. The two ends of the buffer spring are respectively fixedly connected to the upper end face of the compression spring piston and the lower end face of the tapered steel end cap.
[0007] A further feature of this invention is that a binding sleeve is threaded onto the upper end of the pull rod, and a threading hole is provided through the binding sleeve.
[0008] A further feature of this invention is that a set of hammering plates is fixedly provided on the side of the tapered steel end cap, and the surface of the hammering plates is parallel to the horizontal plane.
[0009] A further feature of this invention is that a pressure valve tube is fixedly and through-sleeved onto the bottom end face of the buffer cylinder and the plate surface of the conical steel end cap, respectively. The upper and lower ends of the pressure valve tube are closed, and a set of vent holes are circumferentially arrayed through the side walls of the upper and lower ends of the pressure valve tube. A compression spring is fixedly connected to the inner end face of the upper and lower ends of the pressure valve tube, and a piston valve is vertically and slidably sleeved inside the pressure valve tube. The upper and lower end faces of the piston valve rest against the end faces of the upper and lower compression springs, respectively.
[0010] A further feature of this invention is that a ferrule is fixedly sleeved on the outer side of the upper end of the steel cylinder.
[0011] A further feature of this invention is that a set of wire-applying roller seats are fixedly connected to the inner wall of the upper end of the wire-applying steel cylinder in a circumferential array. A wire-applying roller is rotatably installed on the side of the wire-applying roller seat away from the cylinder wall of the wire-applying steel cylinder, and the roller axis of the wire-applying roller is perpendicular to the cylinder axis of the wire-applying steel cylinder.

[0013] 2. This utility model fixes a sleeve steel cylinder at the upper end of the tapered steel end cap and sleeves the sleeve steel cylinder on the outside of the grounding wire to prevent external force from damaging the connection between the grounding wire and the buffer component, causing the grounding wire to come off.

Detailed Implementation
[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1 Please see Figures 1 to 4 This utility model is a grounding angle steel for preventing wire derailment, including a buried cone steel 1, a sleeve steel cylinder 2, and a buffer assembly 3. By fixing a cone steel end cap 101 to the upper opening of the buried cone steel 1, and fixing the buffer assembly 3 to the lower end face of the cone steel end cap 101, one end of the grounding wire is connected to the buffer assembly 3, and the buried cone steel 1 is buried underground. When tensile stress is generated between the grounding wire and the buffer assembly 3, the buffer assembly 3 will buffer the tensile stress, thereby preventing the grounding wire from being pulled apart and causing derailment. By fixing the sleeve steel cylinder 2 to the upper end of the cone steel end cap 101, the sleeve steel cylinder 2 is sleeved on the outside of the grounding wire to prevent external force from damaging the connection between the grounding wire and the buffer assembly 3, thus preventing the grounding wire from derailing.
[0024] Specifically, the embedded conical steel 1 has a triangular tube structure, the lower end of the embedded conical steel 1 is a pointed cone, the upper end opening of the embedded conical steel 1 is fixedly sleeved with a conical steel end cap 101, the sleeve steel cylinder 2 is fixedly installed on the upper end face of the conical steel end cap 101, and the buffer assembly 3 is installed on the lower end face of the conical steel end cap 101.
[0025] Furthermore, the buffer assembly 3 includes a buffer cylinder 301, a buffer spring 302, and a pull rod 303. The lower end of the buffer cylinder 301 is closed, and the upper end of the buffer cylinder 301 is fixedly connected to the lower end face of the tapered steel end cap 101. The buffer spring 302 is sleeved in the buffer cylinder 301. The lower end of the pull rod 303 is fixedly provided with a compression spring piston 303a, which is vertically slidably sleeved in the buffer cylinder 301. The pull rod 303 passes through the tapered steel end cap 101 and extends into the sleeve steel cylinder 2. The two ends of the buffer spring 302 are respectively fixedly connected to the upper end face of the compression spring piston 303a and the lower end face of the tapered steel end cap 101.
[0026] Furthermore, a binding sleeve 303b is screwed onto the upper end of the pull rod 303. A wire-passing hole 303b-1 is provided on the binding sleeve 303b. The grounding wire is passed through the wire-passing hole 303b-1 and tied to the outside of the binding sleeve 303b. When the grounding wire is subjected to tensile stress, the grounding wire pulls the pull rod 303, causing the compression spring piston 303a at the lower end of the pull rod 303 to compress the buffer spring 302, thereby buffering the tensile stress on the grounding wire and preventing the grounding wire from coming off.
[0027] Furthermore, a set of hammering plates 101a are fixed on the side of the conical steel end cap 101. The surface of the hammering plates 101a is parallel to the horizontal plane. When installing the embedded conical steel 1, the embedded conical steel 1 is inserted into the ground and the hammering plates 101a are hammered, thereby inserting the embedded conical steel 1 into the ground.
[0028] Furthermore, pressure valve tubes 304 are fixedly and through-sleeved onto the bottom end face of the buffer cylinder 301 and the plate surface of the conical steel end cap 101, respectively. The upper and lower ends of the pressure valve tube 304 are closed, and a set of vent holes 304a are circumferentially arrayed through the side walls of both the upper and lower ends of the pressure valve tube 304. A compression spring 304b is fixedly connected to the inner end face of the upper and lower ends of the pressure valve tube 304, respectively. A piston valve 304b-1 is vertically slidably sleeved inside the pressure valve tube 304. The upper and lower end faces of the piston valve 304b-1 respectively abut against the end faces of the upper and lower compression springs 304b. When the compression spring piston 303a slides in the buffer cylinder 301, the compression spring piston 303a pushes the buffer cylinder 301... Gas is pushed into the pressure valve tube 304, causing the gas to push the piston valve 304b-1 and compress the compression spring 304b. When the piston valve 304b-1 is pushed to the vent hole 304a, the gas is discharged from the vent hole 304a, allowing the compression spring piston 303a to slide in the buffer cylinder 301. This prevents the pressure at one end of the compression spring piston 303a from being too high, which would prevent the compression spring piston 303a from moving. When the compression spring piston 303a stops sliding, the compression spring 304b pushes the piston valve 304b-1 to the middle section of the pressure valve tube 304, thereby preventing external air from communicating with the inside of the buffer cylinder 301 and preventing moisture from entering the buffer cylinder 301 and causing oxidation and corrosion of the buffer spring 302.
[0029] The operation process in this embodiment is as follows: When installing the embedded cone steel 1, the embedded cone steel 1 is inserted into the ground and hammered against the hammer plate 101a, thereby inserting the embedded cone steel 1 into the ground. The grounding wire is passed through the wire hole 303b-1 and tied to the outside of the binding sleeve 303b. When the grounding wire is subjected to tensile stress, the grounding wire pulls the pull rod 303, causing the compression spring piston 303a at the lower end of the pull rod 303 to compress the buffer spring 302, thereby buffering the tensile stress on the grounding wire and preventing the grounding wire from coming off.
[0030] Example 2 Please see Figures 1 to 5 Based on Example 1, by attaching a sleeving sleeve 201 to the upper end of the cable sleeve 2 and placing the sleeving sleeve 201 on the outside of the grounding wire, external humid air is prevented from entering the cable sleeve 2 and corroding the grounding wire connection.
[0031] Specifically, a ferrule sleeve 201 is fixedly sleeved on the outer side of the upper end of the steel cylinder 2.
[0032] Furthermore, a set of wire-applying roller seats 202 are fixedly connected to the inner wall of the upper end of the wire sleeve 2 in a circumferential array. A wire-applying roller 202a is rotatably installed on the side of the wire-applying roller seat 202 away from the cylinder wall of the wire sleeve 2. The roller axis of the wire-applying roller 202a is perpendicular to the cylinder axis of the wire sleeve 2. When the grounding wire is subjected to tensile stress, the grounding wire comes into contact with the roller surface of the wire-applying roller 202a through friction, thereby preventing the insulation of the grounding wire from being cut at the end of the wire sleeve 2.
[0033] The operation process in this embodiment is as follows: The sleeve 201 is fitted onto the outside of the grounding wire to prevent external humid air from entering the sleeve steel cylinder 2 and corroding the grounding wire connection. When the grounding wire is subjected to tensile stress, the grounding wire comes into contact with the roller surface of the wire-sticking roller 202a through friction, thereby preventing the insulation of the grounding wire from being cut by the end of the sleeve steel cylinder 2.
