Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting device technology, and in particular to a lifting device for welding spray gun tubes. Background Technology
[0002] Currently, in the welding of spray gun pipes, it is necessary to manually or by crane lift the pipes to the predetermined welding height for welding connection. However, the above lifting methods have the following drawbacks: ① Low efficiency and high labor intensity, especially for heavy pipes; ② Insufficient positioning accuracy by manual labor, which can easily lead to weld misalignment; ③ Poor crane operation flexibility, making it difficult to adapt to confined working spaces; ④ There is a safety hazard of workers being injured by falling pipes.
[0003] Therefore, how to design a lifting device for spray gun welding that is simple in structure, easy to operate, low in labor intensity, stable in lifting, accurate in positioning, highly adaptable to working space, and has a high safety factor is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0004] This utility model provides a lifting device for spray gun tube welding, which solves the technical problems of high labor intensity, low efficiency, insufficient positioning accuracy, poor adaptability to working space, and easy injury to workers when lifting the spray gun tube in existing spray gun tube welding.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a lifting device for welding spray gun pipes, comprising: a traveling frame, at least two guide slide rods, a lifting plate for supporting the spray gun pipe, and at least two lifting mechanisms.
[0006] At least two of the guide slide rods are arranged along the height direction of the traveling frame and their bottom ends are fixed to the traveling frame at intervals; the lifting plate is arranged perpendicular to the height direction of the traveling frame and is located between the at least two guide slide rods, and at least two sliders are fixed at intervals on the edge of the lifting plate. Each of the at least two sliders is provided with a sliding hole and is slidably sleeved on the outside of the at least two guide slide rods through the sliding hole; the fixed ends of the at least two lifting mechanisms are respectively fixed to the top ends of the at least two guide slide rods and their lifting ends reciprocate along the height direction of the traveling frame; at least two sliders are respectively fixed to the lifting ends of the at least two lifting mechanisms to link the lifting plate to reciprocate along the height direction of the traveling frame.
[0007] The beneficial effects of this utility model are: it improves the traditional method of lifting the spray gun pipe manually or by crane. First, the spray gun pipe to be welded is placed on the lifting plate, and then the lifting plate and the spray gun pipe on it are pulled up by the lifting ends of at least two lifting mechanisms. This can raise the height of the spray gun pipe smoothly and accurately, reduce the labor intensity of workers, adapt to various narrow working spaces, and improve the safety of spray gun pipe welding lifting operations.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Furthermore, the walking frame includes a fixed frame and a plurality of pulleys, one side of the fixed frame being open; the plurality of pulleys rotating at intervals at the bottom end of the fixed frame; and the bottom ends of at least two guide rods being fixed at intervals at the top end of the fixed frame.
[0010] The further beneficial effect of adopting the above is that by rotating multiple pulleys at intervals on the fixed frame, it is easier to move the lifting device.
[0011] Furthermore, the walking frame also includes multiple reinforcing plates, which are respectively fixed at the inner corners of the fixed frame.
[0012] The further beneficial effect of adopting the above is that by fixing multiple reinforcing plates to the inner corners of the fixed frame, the structural strength of the walking frame can be improved.
[0013] Furthermore, it also includes an arc-shaped guard plate, which is located above the lifting plate and its arc direction is arranged along the height direction perpendicular to the walking frame. The two ends of the arc-shaped guard plate are respectively fixed to the upper ends of two adjacent guide slide rods.
[0014] The further beneficial effect of adopting the above is that by fixing the two ends of the arc-shaped guard plate to the upper ends of two adjacent guide slides, it can contact the spray gun pipe when the spray gun pipe rises to the welding position, preventing the spray gun pipe from falling abnormally and injuring workers, thus improving the safety of spray gun pipe welding operations.
[0015] Furthermore, the walking frame, at least two of the guide rods, the lifting plate, and at least two of the sliders are all made of metal.
[0016] Furthermore, at least two of the lifting mechanisms are hand-operated hoists. Attached Figure Description
