Mast cantilever crane

Abstract

The invention provides a mast cantilever crane, and belongs to the field of oil and gas well operation equipment. The mast cantilever crane comprises a telescopic arm and a supporting tube arranged onan outer ring of the telescopic arm in a sleeving mode, the supporting tube is fixed to a mast, the telescopic arm and the supporting tube are slidably connected along the axis of the telescopic arm,a driven gear is fixedly arranged at the lower end of the exterior of the supporting tube, a driving gear and the driven gear are disposed in an engagement mode, and the driving gear is driven by a rotating motor fixedly locked on the mast. The mast cantilever crane is scalable and rotatable, and operation is convenient, fast, capable of saving energy and efficient.

Description

technical field [0001] The invention belongs to the field of oil and gas well operation equipment, and relates to a mast cantilever crane. Background technique [0002] In the process of traditional underground operations, due to the large number of operating equipment and devices required, after the equipment is transported to the operating site by truck, it needs to be unloaded by a crane and installed in place. After the operation is completed, it also needs to be lifted and loaded by a crane. During the operation , the oil pipes that need to be repaired need to be hoisted and transported by a crane. The crane plays a very important role in the whole process of traditional operations. The traditional crane pre-rotation cost is too high, and the volume is relatively large. Equipment cost and transportation are problems, and the startup of the crane also requires a special The operation by professional technicians also increases the labor cost invisibly. Since the crane is ...

[0002] In the process of traditional underground operations, due to the large number of operating equipment and devices required, after the equipment is transported to the operating site by truck, it needs to be unloaded by a crane and installed in place. After the operation is completed, it also needs to be lifted and loaded by a crane. During the operation , the oil pipes that need to be repaired need to be hoisted and transported by a crane. The crane plays a very important role in the whole process of traditional operations. The traditional crane pre-rotation cost is too high, and the volume is relatively large. Equipment cost and transportation are problems, and the startup of the crane also requires a special The operation by professional technicians also increases the labor cost invisibly. Since the crane is needed in many links, the crane almost lasts the entire underground operation process, but the intermittent time is long and the utilization rate is not very high, resulting in waste of equipment
