Description

Technical Field

[0001] The utility model mainly relates to the technical field of cranes, in particular to a mobile crane used in a water plant. Background Art

[0002] Generally, the equipment used in the actual production of water plants will inevitably be damaged after a long period of operation, and the equipment will need to be replaced and repaired due to a long service life. Therefore, in addition to disassembling the equipment, the next step is how to transport it out of the site. Most of the important operating equipment in the water plant is placed below the ground, such as large valves, pumps, mixers, etc., and the depth is too long from the ground. After the equipment is disassembled, how to properly hoist it to ensure the safety of equipment and personnel, save manpower, equipment and other costs, and improve work efficiency has become a difficult problem.

[0003] At present, the common way to hoist equipment is to use a crane or a small mobile crane. Although the crane has sufficient load capacity and good stability, it also has high cost and cannot be used in some narrow and special working spaces. Although the common small mobile crane is easy to use and low cost, it has certain limitations in load capacity and stability due to its own design structure.

[0004] Therefore, a mobile crane applied to a water plant is needed to solve the above problems. Utility Model Content

[0005] The technical solution of the utility model aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technology. It mainly provides a mobile crane used in a water plant to solve the technical problems raised in the above-mentioned background technology.

[0006] The utility model adopts the following technical solution to solve the above technical problems: a mobile crane used in a water plant, comprising a frame, the bottom of the frame is connected and fixed to a traction motor, the traction motor is electrically connected to a generator, the output end of the traction motor is connected and fixed to one end of a traction rope, the other end of the traction rope is connected and fixed to a hook, the top of the frame is connected and fixed to equidistantly arranged fixed blocks, the fixed blocks are slidably connected to an adjusting rod, the adjusting rod is in sliding contact with the traction rope, and the outer ring of the adjusting rod is slidably connected to a support rod.

[0007] Preferably, a first threaded hole is provided at the bottom of the support rod, the first threaded hole is threadedly connected to the adjusting screw, and the bottom of the adjusting screw is connected and fixed to the support block.

[0008] Preferably, the bottom of the support block is connected and fixed to a rubber pad.

[0009] Preferably, a groove is formed at the bottom of the adjusting rod, a through hole is formed on one side of the groove, and a second threaded hole is formed on the other side of the groove, and the second threaded hole is threadedly connected to the anti-wear structure, and the anti-wear structure includes a fixing rod, and the outer ring of the fixing rod is slidably connected to the inner ring of the bearing, and the outer ring of the end of the fixing rod is threaded, and the end of the fixing rod is threadedly connected to the second threaded hole.

[0010] Preferably, the side surfaces of the frame are fixedly connected to both ends of the reinforcing rod, and the bottom of the frame is fixedly connected to the universal wheel.

[0011] Preferably, one end of the adjustment rod away from the support rod is rotatably connected to the middle position of the rotating rod.

[0012] Compared with the prior art, the beneficial effect of the utility model is that in the case of no fixed frame position, the frame cannot bear the heavy objects and may tip over. However, by sliding the adjusting rod out of the fixed block and then sliding the supporting rod to one end of the adjusting rod, the load-bearing capacity when lifting the heavy objects can be increased. In addition, when there are sufficient supporting positions, the supporting rod slide and the adjusting rod can also be changed to gantry lifting, which is more stable.
