Description

Technical Field

[0001] The utility model relates to the field of welding equipment, in particular to a self-tightening lifting platform for auxiliary submerged arc welding. Background Art

[0002] Submerged arc welding is a common arc welding method that is suitable for welding a variety of metal materials, including steel, stainless steel and aluminum. During the submerged arc welding process, the wire core of the electrode, called the electrode or wire, is heated and melted by an electric current, producing an electric spark called an arc. The weld area is formed by the arc and the metal melted by the wire, while a powder or granules called welding flux is also used to protect the weld area from atmospheric oxidation.

[0003] However, the following problems are often encountered in the existing submerged arc welding process:

[0004] (1) Since the welding of pipe sections has different process requirements, it is necessary to heat to a specified temperature range for welding, which causes the weld to be raised at different heights. In the prior art, when welding the longitudinal seams of pipe sections, the submerged arc welding rails need to be fixed at different heights. Therefore, the bracket that provides support for the submerged arc welding rails also needs to be adjusted in height, but the existing bracket equipment is not easy to adjust in height.

[0005] (2) Since the submerged arc welding process requires the welding shaft to drive the pipe section to rotate, the rotation of the pipe section will inevitably cause slippage. If auxiliary parts are used to fix the welding shaft, it will be inconvenient to disassemble and replace. Utility Model Content

[0006] The main purpose of the utility model is to provide a self-tightening lifting platform for auxiliary submerged arc welding, so as to effectively solve the problem that the existing bracket equipment mentioned in the background technology is difficult to adjust the height.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A self-tightening lifting platform for auxiliary submerged arc welding, comprising:

[0009] A base, wherein at least two of the bases are arranged parallel to the ground;

[0010] A lifting shell, wherein two lifting shells are provided, and the two lifting shells are longitudinally arranged on the base;

[0011] A lifting rod, wherein two lifting rods are provided, and the bottom ends of the two lifting rods are respectively plugged into the lifting shell;

[0012] A bolt, wherein the bolt is disposed on one side of the lifting shell, and one end of the bolt passes through the lifting shell and contacts one side of the lifting rod;

[0013] A supporting beam, the supporting beam being mounted on the top of the lifting rod;

[0014] Notches, at least two of which are provided on the supporting crossbeam.

[0018] A sleeve connector is sleeved on one end of the supporting beam, and one end of the sleeve connector is movably connected to two sides of the pressure-bearing member.

[0019] The number of the bolts provided corresponds to the lifting shell.

[0020] The top ends of the two springs are connected to the two pressure-bearing members respectively.

[0021] The number of the sleeve parts corresponds to the pressure-bearing parts.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] (1) The self-tightening lifting platform designed by the utility model is adjusted by setting a supporting crossbeam. The supporting crossbeam and the base can be overlapped and extended to adjust the height requirements. It is locked by bolts and can be more comprehensively applied to more welding environments. The platform has a simple structure, low cost and simple operation.

[0024] (2) The supporting crossbeam designed in the utility model is provided with a notch, and the arrangement of the notch can effectively limit the range of motion of the welding shaft, making it difficult to fall off. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "set", "connected", and "connected" should be understood in a broad sense, for example, it 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figure 1-2 As shown, a self-tightening lifting platform for assisting submerged arc welding comprises: a base 1, a lifting shell 2, a lifting rod 3, a bolt 4, a supporting crossbeam 5, and a notch 6. At least two bases 1 are arranged in parallel on the ground, two lifting shells 2 are arranged, and the two lifting shells 2 are arranged longitudinally on the base 1, and two lifting rods 3 are arranged. The bottom ends of the two lifting rods 3 are respectively plugged into the lifting shell 2, and the bolt 4 is arranged on one side of the lifting shell 2. One end of the bolt 4 is inserted through the lifting shell 2 and contacts one side of the lifting rod 3. The number of the bolts 4 is corresponding to the lifting shell 2. The lifting rod 3 is supported by the bolt 4 against the lifting rod 3, and the lifting rod 3 is supported by the extrusion force. At least two notches 6 are opened on the supporting crossbeam 5. The notch 6 is arranged so that the welding shaft is placed on the notch 6 when performing the submerged arc welding operation. In this way, if the welding shaft needs to drive the pipe section to rotate, its rolling range will be limited by the edges on both sides of the notch 6, so that it is not easy to fall off.

[0032] In this embodiment, Figure 2As shown, if the welding shaft is in direct contact with the edges on both sides of the slot 6, the friction will increase, thereby increasing the rotational resistance. In order to reduce the friction, two pressure-bearing parts 7 are provided, and the two pressure-bearing parts 7 are located in the slot 6. Two springs 8 are provided, and the two springs 8 are respectively longitudinally arranged in the slot 6. The sleeve 9 is sleeved on one end of the supporting beam 5, and one end of the sleeve 9 is movably connected to the two sides of the pressure-bearing part 7. Once the welding shaft is placed on the slot 6, the pressure-bearing part 7 in the slot 6 will receive pressure and squeeze the spring 8. One end of the sleeve 9 will also be tilted due to the downward pressure of the pressure-bearing part 7. The inclined surface of the inclined sleeve 9 is more gentle than the vertical edge of the slot 6, so the friction is smaller.

[0033] In the above embodiment, as shown in the figure, when the welding shaft is lifted, the spring 8 will rebound to lift the pressure-bearing member 7 to prevent the notch 6 from being accumulated with dust.

[0034] It should be noted that the utility model is designed to be a self-tightening lifting platform for auxiliary submerged arc welding. When in use, according to the height of the welding track, loosen the bolt 4, manually pull the supporting beam 5 to adjust it to fit the welding shaft, so that the welding shaft presses the pressure-bearing part 7 downward, and the pressure-bearing part 7 receives the pressure and squeezes the spring 8. One end of the socket 9 will also be tilted due to the downward pressure of the pressure-bearing part 7. At this time, use the bolt 4 for locking, and the height adjustment is completed quickly and conveniently.

[0035] Although the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
