Description

Technical Field

[0001] This utility model relates to the technical field of grounding electrode recycling equipment, specifically a grounding electrode recycling tool. Background Technology

[0002] Installing grounding electrodes during mine production is a core measure to ensure electrical safety in mines. Its fundamental purpose is to maximize the safety of personnel and equipment, especially in special hazardous environments such as high gas, high dust, humid environment, confined space, dense electrical equipment, and prone to failure. However, due to the dynamic nature of the underground environment and production, grounding electrodes may fail or become unnecessary and be abandoned for various reasons. Abandoned grounding electrodes can trip personnel when they are not paying attention, causing injury. The remaining metal conductors become channels for stray currents, generating electric sparks at broken or poorly connected points, which can become potential ignition sources for gas and coal dust explosions. If abandoned grounding electrodes are not properly removed, maintenance personnel may mistakenly connect them as effective grounding electrodes, resulting in false grounding of equipment and causing safety hazards.

For example, "connected" 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 an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] 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.

[0019] Example 1: Please refer to Figure 1-4 One embodiment of this utility model provides a grounding electrode recycling tool, comprising a counterweight plate 1, a guide frame 2, a jack 3, a sliding plate 4, and a grounding electrode clamping device. Two counterweight plates 1 are provided, symmetrically placed on the left and right sides of the grounding electrode. This symmetrical arrangement provides foundation stability and anti-overturning force, preventing equipment displacement during lifting. The counterweight plates 1 also have sufficient self-weight to support the guide frame 2 and mitigate swaying during lifting. A vertically erected rectangular guide frame 2 is mounted on the counterweight plates 1. Internal guide grooves constrain the movement trajectory of the sliding plate 4, ensuring vertical lifting without deviation. Guide grooves are formed on corresponding end faces of the rectangular guide frame 2, and the sliding plate 4 is housed within these grooves. The sliding plate 4 is L-shaped, with its lateral end slidingly engaged with the guide frame 2. A grounding electrode clamping device is connected to its vertical end, and the lateral end is driven by a jack 3. The grounding electrode slides within the guide groove, simultaneously causing the vertical end of the clamping device to slide upwards, pulling the clamped grounding electrode out of the mine surface for disassembly. A jack 3 is provided between the counterweight plate 1 and the transverse end of the slide plate 4. The piston rod of the jack 3 is connected to the top of the slide plate 4. The jack 3 is the power source for lifting; the piston rod pushes the slide plate 4 upwards, providing the main driving force required to remove the grounding electrode. The jack 3 in this application is a commonly available hand-operated jack 3. The working principle of the jack 3 is existing technology and will not be elaborated upon in this application. The grounding electrode clamping device includes a threaded rod 5 and a clamping plate 6. An internally threaded through hole is opened in the middle of the vertical end of the slide plate 4, and a threaded rod is provided on the through hole. 5. The threaded rod 5 passes through the internal threaded through hole and is connected to a clamping plate 6 at its top. The distance between the two clamping plates 6 can be adjusted by rotation to accommodate grounding electrodes of different diameters. Triangular grooves are respectively opened on the corresponding end faces of the two clamping plates 6. The triangular grooves abut against the outer circumference of the grounding electrode, and the triangular grooves engage with the circumference of the grounding electrode to provide a self-locking grip. The contact end between the guide frame 2 and the counterweight plate 1 is detachable. The top of the counterweight plate 1 is provided with an I-beam mounting seat 101, and the bottom of the guide frame 2 is provided with a mounting groove 201 that mates with the mounting seat 101. The guide frame 2 slides on the counterweight plate 1. The detachable design of the guide frame 2 and the counterweight plate 1 facilitates underground transportation and installation. The installation is completed as a whole in the mine, thus removing the grounding electrode. It also includes a telescopic rod 7, which is connected between the drive rods of the two jacks 3. The left and right ends of the telescopic rod 7 are respectively connected to sleeves, which are respectively fitted onto the drive rods of the jacks 3, connecting the drive rods of the two jacks 3 into a whole. This facilitates installation and disassembly, forces synchronous lifting on both sides, and avoids tilting and jamming of the slide plate 4 caused by lifting on one side. A bearing seat is provided between the contact end of the threaded rod 5 and the clamping plate 6. A limit baffle 102 is connected to the end of either side of the mounting base 101 to constrain the sliding range of the guide frame 2 on the I-beam mounting base 101 and prevent accidental dislocation caused by vibration.

[0020] In use, place the two counterweight plates 1 symmetrically on both sides of the grounding electrode. The mounting groove 201 at the bottom of the guide frame 2 is connected to the I-beam mounting base 101. The limiting baffle 102 locks the position of the guide frame 2 to prevent displacement during operation. Rotate the threaded rods 5 on both sides to push the clamping plate 6 towards the grounding electrode. The triangular groove abuts against the outer circumference of the grounding electrode and clamps it. At the same time, install the telescopic rod 7 to connect the drive rods of the two jacks 3 into a whole. Simultaneously drive the jacks 3. The piston rod pushes the horizontal end of the slide plate 4 to rise along the guide groove, and simultaneously drives the vertical end of the slide plate 4 to rise. Remove the grounding electrode. After the grounding electrode is completely removed, reverse the threaded rod 5 to release the clamping plate 6, disassemble the guide frame 2 and the counterweight plate 1, and transfer to the next work point.

[0021] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
