Description

Technical Field

[0001] This utility model relates to the field of grounding round steel construction technology, and in particular to a grounding round steel installation excavation-free device. Background Technology

[0002] Grounding round steel, also known as a grounding electrode, is a metal conductor or group of conductors in direct contact with the soil. During construction and installation, grounding electrodes are typically installed by hammering or by mechanical excavation and direct burial. Mechanical excavation and direct burial is labor-intensive, time-consuming, and difficult to operate in confined spaces. When using round steel as a grounding electrode, the direct hammering method can cause the steel to bend during the hammering process, making it impossible to continue hammering into the soil. Therefore, a device is needed to ensure that the grounding round steel can be successfully hammered into the soil.

[0003] A round steel grounding electrode installation device disclosed in Chinese Patent CN220456679U involves inserting the round steel grounding electrode into a cylindrical body, striking the lowest striking bracket, stopping the striking when the open end of the cylinder is close to the ground, lifting the cylinder upwards until the highest pin hole is above the top of the round steel grounding electrode, inserting a pin into the pin hole so that the pin contacts the striking surface of the grounding electrode, and then continuing to strike on the striking bracket until the bottom of the cylinder is close to the ground. However, this round steel grounding electrode installation device, while solving the problem, has the following drawbacks:

[0004] When striking, two people need to strike the two crossbars of the striking bracket simultaneously. If there is a time difference between the two people striking, a tilting force will be generated, which will directly cause the grounding round steel to bend. However, it is difficult to achieve two people striking at the same time in actual operation. Therefore, the device is inconvenient to operate and easily damages the grounding round steel. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0006] Therefore, one objective of this utility model is to propose a trenchless installation device for grounding round steel, which aims to solve the problems of inconvenient operation and easy damage to the grounding round steel in the existing round steel grounding electrode installation device.

[0007] To achieve the above objectives, one embodiment of the present invention provides a grounding round steel installation trenchless device, including a cylinder, the outer surface of which is provided with a fixing mechanism for fixing the grounding round steel, a guide tube welded and fixed to the top of the cylinder, the guide tube communicating with the middle of the cylinder, a pressure ring welded and fixed to the outer surface of the top of the cylinder, a hammer head slidably sleeved on the outer surface of the guide tube, and two symmetrical traction ropes fixedly connected to the outer surface of the hammer head.

[0008] The beneficial effects are as follows: After the grounding round steel is fixed inside the cylinder, two operators can raise the hammer head upward along the guide tube using two traction ropes. By pulling the traction ropes downward, the falling speed of the hammer head can be accelerated. When the hammer head hits the pressure ring, it will hammer the grounding round steel into the ground. The operation is simple and convenient, with two people operating one hammer head to hammer the grounding round steel into the ground. Moreover, the movement direction of the hammer head is parallel to the grounding round steel and is perpendicular to the ground, so the grounding round steel is not easy to bend or be damaged.

[0009] In a preferred embodiment, multiple reinforcing plates are welded and fixed to the bottom of the pressure ring, and the other side of the reinforcing plates is welded and fixed to the outer surface of the cylinder to reinforce the pressure ring and prevent the weld from cracking when hit by a hammer.

[0010] In a preferred embodiment, the fixing mechanism includes multiple threaded sleeves, which are welded and fixed to the outer surface of the cylinder. The internal threads of each threaded sleeve are connected to a positioning screw, which penetrates into the interior of the cylinder.

[0011] In a preferred embodiment, the fixing mechanism includes multiple swing arms, which are hinged to the outer surface of the cylinder. A clamping block is fixedly connected to the inner side of the bottom end of each swing arm, and a push plate is fixedly connected to the top end of each swing arm. A V-shaped spring sheet is welded and fixed to the side of the push plate near the cylinder, and the V-shaped spring sheet provides elastic support to the push plate.

[0012] Furthermore, the outer surface of the cylinder is provided with multiple slots, and the slots are located below the hinge joint between the swing arm and the cylinder. When no external force is applied, the bottom end of the swing arm tilts into the slots, and the clamping block passes through the slots and is located inside the cylinder.

[0013] The beneficial effects are as follows: after a portion of the grounding round steel is hammered into the ground, when it is necessary to raise the device on the surface of the grounding round steel, the device can be lifted directly by holding the guide tube or other parts of the device. There is no need to manually loosen the fixing mechanism of the grounding round steel, thus simplifying the operation and improving construction efficiency.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] This utility model provides a grounding round steel installation device that does not require excavation.

[0024] Example 1:

[0025] like Figure 1-2As shown, it includes a cylindrical body 1. Multiple threaded sleeves 2 are welded and fixed on the outer surface of the cylindrical body 1. A through hole is opened on the outer surface of the cylindrical body 1 at a position corresponding to the middle of the threaded sleeve 2. A positioning screw 21 is threadedly connected inside the threaded sleeve 2. The positioning screw 21 can pass through the through hole into the interior of the cylindrical body 1. By tightening the positioning screw 21, the grounding round steel 6 inside the cylindrical body 1 can be pressed against it, so as to fix the grounding round steel 6.

[0026] A conduit 3 is welded and fixed to the top of the cylinder 1. The conduit 3 is connected to the middle of the cylinder 1. The conduit 3 is sleeved on the outer surface of the grounding round steel 6. A pressure ring 4 is welded and fixed to the outer surface of the top of the cylinder 1. Multiple reinforcing plates 41 are welded and fixed to the bottom of the pressure ring 4. The other side of the reinforcing plate 41 is welded and fixed to the outer surface of the cylinder 1 to reinforce the pressure ring 4 and prevent the weld from cracking when it is hammered by the hammer head 31. The hammer head 31 is slidably sleeved on the outer surface of the conduit 3, and two symmetrical traction ropes 32 are fixedly connected to the outer surface of the hammer head 31.

[0027] The working principle of this embodiment is as follows: When in use, the grounding round steel 6 is inserted into the conduit 3 and the cylinder 1, with the bottom part of the grounding round steel 6 exposed below the cylinder 1. Then, by tightening the positioning screw 21, its end is made to penetrate into the cylinder 1 and the grounding round steel 6 is fixed. Then, the grounding round steel 6 is placed vertically on the ground. Two construction workers hold the grounding round steel 6 with one hand to prevent it from tipping over. The two construction workers pull the hammer head 31 up with two traction ropes 32 respectively. After pulling it up to a certain height, they pull the hammer head 31 down in the opposite direction to accelerate the descent speed of the hammer head 31. After the hammer head 31 presses the pile foundation ring 4, the grounding round steel 6 is hammered into the soil. The operation is repeated until all the grounding round steel 6 below the cylinder 1 is hammered into the soil.

[0028] Loosen the positioning screw 21 again, pull the device up along the grounding round steel 6, and after it rises to a certain height, tighten the positioning screw 21 again. Then, hammer the pressure ring 4 with the hammer head 31 and continue to drive the grounding round steel 6 into the ground. Repeat the above operation until the grounding round steel 6 is driven into the ground to a certain depth.

[0029] Example 2:

[0030] like Figure 3-4 As shown, the structure of the fixed grounding round steel 6 has been further improved based on Embodiment 1. The difference is that multiple slots 11 are opened on the outer surface of the cylinder 1. A swing arm 5 is hinged to the top of each slot 11. A rubber clamp 51 is fixedly connected to the inner side of the bottom end of the swing arm 5. A push plate 52 is fixedly connected to the top end of the swing arm 5. A V-shaped spring plate 53 is welded and fixed to the side of the push plate 52 near the cylinder 1. The other end of the V-shaped spring plate 53 contacts the outer wall of the cylinder 1 to provide elastic support for the push plate 52. When there is no external force, the bottom end of the swing arm 5 tilts into the slot 11, and the clamp 51 passes through the slot 11 and is located inside the cylinder 1.

[0031] The working principle of this embodiment is as follows: When in use, the grounding round steel 6 is inserted from the top of the conduit 3. The sharp corner of the bottom of the grounding round steel 6 passes through multiple clamps 51. The inclined surface of the sharp corner pushes the clamps 51 outward, causing the swing arm 5 to rotate. The push plate 52 compresses the V-shaped spring plate 53, so that the grounding round steel 6 can pass smoothly downward through the cylinder 1.

[0032] When the hammer head 31 is used to hammer the pressure ring 4, the cylinder 1 is subjected to a downward force, the friction between the clamping block 51 and the grounding round steel 6 is upward, and the bottom end of the swing arm 5 is inclined into the slot 11. As a result, the friction causes multiple swing arms 5 to tighten into the slot 11, thereby clamping the grounding round steel 6 and ensuring that the grounding round steel 6 can be hammered into the ground.

[0033] When the grounding round steel 6 below the cylinder 1 is completely driven into the ground, simply pull the device upwards. The clamping block 51 will move outwards from the slot 11 under force, and the bottom end of the swing arm 5 will rotate outwards from the slot 11, compressing the V-shaped spring plate 53. After the device slides upwards to a certain height on the surface of the grounding round steel 6, release the device, and the clamping block 51 will clamp the grounding round steel 6 again. Therefore, no additional operation is required to clamp and fix the grounding round steel 6, which improves construction efficiency.
