[0002] Lightning protection engineering is the most difficult and important sub-item in construction. Due to the different environments, the design of the grounding network also varies greatly. The grounding engineering of the system is mainly composed of grounding bodies and connecting wires to form a grounding network. Among them, several factors that affect the grounding effect include soil resistivity, selection of grounding bodies, corrosion resistance of grounding materials and reasonable layout of the grounding network.

[0003] In the process of welding with an electric welder, it is necessary to use an electric welder cable to connect the welding gun. Since the welding gun needs to be moved during the welding process, a certain length of electric welder cable is required. These cables need to be reeled up after use. In the prior art, the cable is usually reeled up manually and then the reeled cable is hung on a hook. The overall reeling process is relatively cumbersome and more obvious during short-distance movement. In view of this, we propose an electric welder for lightning protection engineering with a safety protection structure. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide an electric welding machine for lightning protection engineering with a safety protection structure, which can solve the problem of complicated and inefficient cable winding process.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric welding machine for lightning protection engineering with a safety protection structure, comprising a base plate, the upper surface of the base plate is fixedly connected to a welding machine body, the front surface of the welding machine body begins to have heat dissipation holes, a storage cavity is opened inside the welding machine body, the inner wall of the storage cavity is rotatably connected to a rotating shaft, the outer surface of the rotating shaft is sleeved with a wire reel, a cable is arranged on the wire reel, a sliding groove is opened on the inner wall of the storage cavity, the inner wall of the sliding groove is slidably connected to a mounting plate, the front surface of the mounting plate is rotatably connected to a rolling shaft, the other end of the cable passes through the rolling shaft and slides through the left surface of the welding machine body, a control handle is arranged on the upper surface of the welding machine body, and a wire take-up assembly is arranged on the rotating shaft.

[0006] Preferably, the wire taking-up assembly includes a torsion spring, which is fixedly connected to the outer surface of the rotating shaft, the front end of the torsion spring is fixedly connected to the inner wall of the storage chamber, the outer surface of the rotating shaft is sleeved with a ratchet, the upper surface of the mounting plate is fixedly connected to a second spring, and the upper end of the second spring is fixedly connected to the top wall of the sliding groove.

[0007] Preferably, a reset cavity is opened inside the welding machine body, a displacement column is fixedly connected to the lower surface of the control handle, the lower end of the displacement column slides into the storage cavity, and reset plates are fixedly connected to the left and right side surfaces of the displacement column.

[0008] Preferably, a spring is fixedly connected to the upper surface of the reset plate, the upper end of the spring is fixedly connected to the top wall of the storage cavity, the lower end of the displacement column is fixedly connected to the limiting plate, and the lower end of the displacement column is fixedly connected to the connecting plate.

[0009] Preferably, the left and right side surfaces of the connecting plate are rotatably connected with second rotating shafts, a locking plate is provided below the connecting plate, the upper surface of the locking plate is fixedly connected with mounting ears, and the opposite ends of the two second rotating shafts are respectively fixedly connected to the two mounting ears.

[0010] Preferably, a second torsion spring is fixedly connected between the connecting plate and the mounting ear, one end of the cable passing through the welding machine body is fixedly connected to a handle, the other end of the handle is fixedly connected to a welding gun, and a protective cover is fixedly connected to the outer surface of the handle.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The electric welding machine for lightning protection engineering with a safety protection structure can work normally. When the length of the cable is insufficient, the cable can be directly pulled to rotate the wire reel to complete the wire release. When the wire reel rotates, the rotating shaft will be driven to rotate synchronously. When the rotating shaft rotates, the subsequent wire reel assembly will be driven to move synchronously, so that the cable will not be rewound. When reeling in the wire, only the operating handle needs to be pulled to cooperate with the wire reel assembly to complete the automatic wire reeling, thereby saving wire reeling time. Through the above structure, when reeling in the cable, only the operating handle needs to be pulled to complete the automatic wire reeling, thereby saving wire reeling time. At the same time, it can also avoid the cable being dragged on the ground and causing wear when moving over short distances, thereby reducing the service life of the cable.

[0013] (2) The electric welding machine for lightning protection engineering with a safety protection structure will drive the locking plate to move upward as a whole when the displacement column moves, thereby unlocking the ratchet, and driving the rotating shaft to rotate under the action of the torsion spring to complete the wire winding. At the same time, when the cable is released to the extreme, continued pulling will cause the rolling shaft to drive the mounting plate to move upward, thereby compressing the second spring, thereby increasing the resistance to wire release, thereby reminding the staff that the cable has been released and avoiding damage to the cable due to continuous pulling. At the same time, during welding, the protective cover can block sparks to avoid damage to the hands. Through the above structure, not only can the resistance generated by the displacement of the rolling shaft after the wire is released remind the staff, but the protective cover can also prevent sparks from causing damage to the staff's hands, thereby improving the safety of use.

During normal operation, when the length of the cable 7 is insufficient, the cable 7 can be directly pulled to make the wire reel 6 rotate, thereby completing the wire release. When the wire reel 6 rotates, the rotating shaft 5 will be synchronously driven to rotate. When the rotating shaft 5 rotates, the subsequent wire-winding assembly will be synchronously driven to move, so that the cable 7 will not be rewound. When winding up the wire, it is only necessary to pull the control handle 14 to cooperate with the wire-winding assembly to complete the automatic winding, thereby saving the winding time. Through the above structure, when winding up the cable 7, it is only necessary to pull the control handle 14 to complete the automatic winding, saving the winding time. At the same time, it can also avoid the cable being dragged on the ground to cause wear during short-distance movement, thereby reducing the service life of the cable.

[0022] Furthermore, the wire take-up assembly includes a torsion spring 11, which is fixedly connected to the outer surface of the rotating shaft 5, the front end of the torsion spring 11 is fixedly connected to the inner wall of the storage chamber 4, the outer surface of the rotating shaft 5 is sleeved with a ratchet 12, the upper surface of the mounting plate 9 is fixedly connected to the second spring 27, the upper end of the second spring 27 is fixedly connected to the top wall of the sliding groove 8, a reset chamber 13 is opened inside the welding machine body 2, the lower surface of the control handle 14 is fixedly connected to the displacement column 15, the lower end of the displacement column 15 slides into the storage chamber 4, the left and right side surfaces of the displacement column 15 are fixedly connected to the reset plate 16, the upper surface of the reset plate 16 is fixedly connected to the spring 17, the upper end of the spring 17 The top wall of the storage chamber 4 is fixedly connected, the lower end of the displacement column 15 is fixedly connected to the limit plate 18, the lower end of the displacement column 15 is fixedly connected to a connecting plate 19, the left and right side surfaces of the connecting plate 19 are rotatably connected to a second rotating shaft 20, a locking plate 21 is provided below the connecting plate 19, the upper surface of the locking plate 21 is fixedly connected to a mounting ear 22, the opposite ends of the two second rotating shafts 20 are respectively fixedly connected to the two mounting ears 22, a second torsion spring 23 is fixedly connected between the connecting plate 19 and the mounting ears 22, one end of the cable 7 passing through the welding machine body 2 is fixedly connected to a handle 24, the other end of the handle 24 is fixedly connected to a welding gun 25, and the outer surface of the handle 24 is fixedly connected to a protective cover 2 6. When the rotating shaft 5 rotates, the torsion spring 11 is compressed synchronously, and the ratchet 12 is also driven to rotate. Since the movement trajectory of the locking plate 21 is limited by the limit plate 18, the ratchet 12 will move the locking plate 21 to rotate during normal line release. When the locking plate 21 rotates, the second rotating shaft 20 is used to compress the second torsion spring 23. After the ratchet teeth on the ratchet 12 pass, the second torsion spring 23 is used to reset the locking plate 21. At the same time, when winding the line, you only need to pull the control handle 14 to drive the displacement column 15 to move. When the displacement column 15 moves, the spring 17 is compressed by the reset plate 16. When the displacement column 15 moves, it will drive the locking plate 21 to move upward as a whole, thereby pressing the ratchet. 12 is unlocked, and the rotating shaft 5 is driven to rotate under the action of the torsion spring 11, thereby completing the wire winding. At the same time, when the cable 7 is released to the extreme, continuing to pull will cause the rolling shaft 10 to drive the mounting plate 9 to move upward, thereby compressing the second spring 27, thereby increasing the resistance of wire release, thereby reminding the staff that the cable 7 is fully released, avoiding damage to the cable 7 caused by continuous pulling. At the same time, during welding, the protective cover 26 can be used to block sparks to avoid damage to the hands. Through the above structure, not only can the resistance generated by the displacement of the rolling shaft 10 after the wire release is completed remind the staff, but the protective cover 26 can also be used to prevent sparks from causing damage to the hands of the staff, thereby improving the safety of use.

[0023] Working principle: In normal operation, when the length of the cable 7 is insufficient, the cable 7 can be directly pulled to make the cable reel 6 rotate, thereby completing the line release. When the cable reel 6 rotates, the rotating shaft 5 will be driven to rotate synchronously, and when the rotating shaft 5 rotates, the subsequent line-reeling assembly will be driven to move synchronously, so that the cable 7 will not be rewound. When reeling in the line, it is only necessary to pull the control handle 14 to cooperate with the line-reeling assembly to complete the automatic line reeling, thereby saving the line reeling time. When the rotating shaft 5 rotates, the torsion spring 11 will be compressed synchronously, and the ratchet 12 will also be driven to rotate. Since the locking plate 21 is restricted in its movement trajectory by the limit plate 18, the ratchet 12 will toggle the locking plate 21 to rotate during normal line release. When the locking plate 21 rotates, the second rotating shaft 20 will be used to compress the second torsion spring 23, and the ratchet 12 will be pressed on the ratchet 12. After the ratchet passes, the second torsion spring 23 will be used to reset the locking plate 21. At the same time, when winding the line, you only need to pull the control handle 14 to drive the displacement column 15 to move. When the displacement column 15 moves, the spring 17 will be compressed by the reset plate 16. When the displacement column 15 moves, it will drive the locking plate 21 to move up as a whole, thereby unlocking the ratchet 12. Under the action of the torsion spring 11, the rotating shaft 5 is driven to rotate, thereby completing the winding. At the same time, when the cable 7 is released to the extreme, continuing to pull will cause the rolling shaft 10 to drive the mounting plate 9 to move up, thereby compressing the second spring 27, thereby increasing the resistance to releasing the line, thereby reminding the staff that the cable 7 has been released, avoiding damage to the cable 7 caused by continuous pulling, and at the same time, during welding, the protective cover 26 can be used to block sparks to avoid damage to the hands.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
