Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyor processing, and particularly relates to a roller beam assembly welding tool for a belt conveyor. Background Art

[0002] Belt conveyors are commonly used equipment for bulk material transportation. They have the advantages of large conveying volume per unit time, long conveying distance, and low conveying cost. More and more such equipment is used in mines, material yards, and other places. Roller beams are the most commonly used welded structural parts of such equipment. There are many specifications and models according to many factors such as the width of the conveyor belt, the state of the conveyed material, and the angle of the conveying path.

[0003] At present, a Chinese utility model with the publication number CN214868387U discloses a roller beam welding fixture for a belt conveyor, including a welding workbench, a bottom beam, and a slide plate. A first connecting seat plate positioning block and a second connecting seat plate positioning block are provided at intervals along the length direction on one side of the top surface of the welding workbench, and the second connecting seat plate positioning block can be horizontally displaced to adjust the spacing between the first connecting seat plate positioning block. A bottom beam is fixed along the length direction on the other side of the top surface of the welding workbench. The bottom beam is spaced apart from the first connecting seat plate positioning block and the second connecting seat plate positioning block. A slide plate is fixed along the length direction on the top surface of the bottom beam, and two side support positioning plates whose positions can be adjusted along the length direction are provided on the top surface of the slide plate. The utility model proposes a roller beam welding fixture for a belt conveyor, in which each positioning dimension can be adjusted, and is suitable for the assembly and welding of roller beams of various specifications and models, while ensuring the consistency of beams of the same specifications and improving the assembly and welding efficiency.

[0004] Since the existing belt conveyor needs to output materials to different heights, the roller beam of the belt conveyor needs to be welded at a certain angle so that the roller support conveying belt can be tilted. The existing roller beam welding tooling can generally only weld the beam support to a fixed tilt angle. When the angle changes, it takes time to adjust, which will affect the efficiency of the roller beam welding. In addition, since the temperature of the welding position of the roller beam is high after welding, it is difficult to fully cool it in a short time. At this time, lifting and carrying away the welded roller beam will easily cause the weld to break. Therefore, it is necessary to wait for the weld to cool down. In this way, the roller beam will occupy the welding tooling during the cooling process, thus affecting the welding of the subsequent roller beams. Utility Model Content

[0005] The utility model aims to provide a roller beam welding tool for a belt conveyor, which has the advantages of being convenient for rotating and lifting the roller beam to different angles for welding, quickly cooling the welding position of the roller beam, and facilitating the collection of debris dropped during welding.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a roller beam welding tool for a belt conveyor, including a support table, a rotating platform is arranged on one side of the top of the support table, a rotating shaft rotatably connected to the support table is fixedly connected to the side of the rotating platform close to the support table, a beam fixing mechanism is installed inside the support table and the rotating platform, a rotating rod is rotatably connected to the side of the rotating platform away from the rotating shaft, first bevel gears are fixedly sleeved on both sides of the rotating rod surface, a second bevel gear used in conjunction with the beam fixing mechanism is meshed on one side of the surface of the first bevel gear, a lifting cylinder is installed on the side of the bottom of the support table close to the rotating platform, and rotating parts rotatably connected to the support table and the rotating platform are installed at both ends of the lifting cylinder.

[0012] The utility model is further configured as follows: the beam fixing mechanism inside the rotating platform is fixedly connected to an end of the second bevel gear away from the first bevel gear through a bidirectional screw.

[0013] By adopting the above technical solution, the two bidirectional screws inside the rotating platform can be rotated synchronously through the second bevel gear, thereby improving the sliding stability of the clamping plate.
