Description

Technical Field

[0001] This utility model belongs to the field of steel structure processing and welding, and in particular provides a device for fixing the welding neutral wire on a steel platform. Background Technology

[0002] When welding steel structures, the welding neutral wire of the welding machine is usually secured by a heavy object, that is, by using a stone or iron block to press down the welding neutral wire on the steel platform. The disadvantages of this method are that, firstly, the stone or iron block may be moved by external force, causing the welding neutral wire to detach from the steel platform; secondly, the welding neutral wire is also easily detached by external force, affecting normal welding. Utility Model Content

[0003] The purpose of this utility model is to provide a welding neutral wire fixing device on a steel platform, which solves the problem of the welding neutral wire detaching from the platform, ensures normal welding, and improves welding efficiency.

[0004] This utility model inserts the slot of the fixing device into the side of the steel platform plate and tightens it with the lower bolt. Then, the welding neutral wire is passed through the upper nut and the sliding notch, and the upper bolt is tightened to fix the welding neutral wire. Then, the steel structure welding is carried out on the steel platform.

[0005] This utility model includes a lower bolt 1, a lower nut 2, a groove 3, an upper nut 4, an upper bolt 5, a sliding roller 6, and a roller 7, which are used in combination. The sliding roller 6 and the roller 7 form a rolling system. The sliding roller 6 can rotate around the roller 7. A notch with a depth of 10mm and a width of 15mm is opened on the outer side of the sliding roller 6. The upper nut 4 is welded to the notch on the side of the sliding roller 6. The upper bolt 5 is screwed into the upper nut 4. The roller 7 is vertically welded to the upper side wall of the groove 3. The lower nut 2 is welded to the lower side wall of the groove 3. The lower bolt 1 is screwed into the lower nut 2 and passes through the lower side wall of the groove 3 (see...). Figure 1 , Figure 2 ).

[0006] Among them, the lower bolt 1 has a diameter of 14mm and a length of 100mm; the lower nut 2 has a diameter of 14mm; the slot 3 is a U-shaped slot made of 12mm thick steel plate, with the side wall dimensions of the U-shaped slot being 100mm x 80mm and the back plate dimensions being 100mm x 60mm; the upper nut 4 has a diameter of 20mm; the upper bolt 5 has a diameter of 20mm and a length of 60mm; the sliding roller 6 is a purchased finished bearing with an outer diameter of 60mm and an inner diameter of 30mm; and the roller 7 has a diameter of 30mm and a length of 80mm.

[0007] In use, insert the slot 3 of the fixing device into the side of the steel platform 8 and tighten it with the lower bolt 1. Then, pass the welding neutral wire 9 through the notch between the upper nut 4 and the sliding roller 6, and tighten the upper bolt 5 to fix the welding neutral wire 9. Then, perform steel structure welding on the steel platform 8. Figure 3 , Figure 4 ).

[0008] The advantages of this invention are that it is easy to assemble, convenient to operate, simple and practical, solves the problem of the welding neutral wire detaching from the platform, ensures normal welding, and improves welding efficiency. Attached Figure Description

[0013] In the diagram, the components are: lower bolt 1, lower nut 2, slot 3, upper nut 4, upper bolt 5, sliding roller 6, roller shaft 7, steel platform 8, and welding neutral wire 9. Detailed Implementation

[0014] Figures 1-4 This is one specific embodiment of the present invention. The present invention will be further described below with reference to the accompanying drawings.

[0015] This utility model includes a lower bolt 1, a lower nut 2, a groove 3, an upper nut 4, an upper bolt 5, a sliding roller 6, and a roller 7, which are used in combination. The sliding roller 6 and the roller 7 form a rolling system. The sliding roller 6 can rotate around the roller 7. A notch with a depth of 10mm and a width of 15mm is opened on the outer side of the sliding roller 6. The upper nut 4 is welded to the notch on the side of the sliding roller 6. The upper bolt 5 is screwed into the upper nut 4. The roller 7 is vertically welded to the upper side wall of the groove 3. The lower nut 2 is welded to the lower side wall of the groove 3. The lower bolt 1 is screwed into the lower nut 2 and passes through the lower side wall of the groove 3.

[0016] In use, insert the slot 3 of the fixing device into the side of the steel platform 8 and tighten it with the lower bolt 1. Then, pass the welding neutral wire 9 through the notch between the upper nut 4 and the sliding roller 6, and tighten the upper bolt 5 to fix the welding neutral wire 9.
