Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing, and the structure and principle of this device are very clear to those skilled in the art. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0031] In the present invention, the hydraulic power device is arranged on the ground, and the power is transmitted to the frame integrating underwater tensioning and cutting through the hydraulic pipeline, and the tensioning and cutting of the wire saw are completed underwater, and the power transmission line of the actuator is more efficient. Shorter, higher energy utilization rate, thereby reducing equipment energy consumption, equipment prices are reduced accordingly, and installation is more convenient. Personnel are controlled and monitored on the ground, so the safety is relatively high.

Abstract

The invention relates to the technical field of engineering construction, in particular to underwater cutting equipment and a cutting method thereof. A hydraulic power device of the underwater cuttingequipment is connected with a feeding device and cutting devices through hydraulic oil pipes. A piston rod of a hydraulic oil cylinder of the feeding device is connected with one or more transmissionparts. Each transmission part is connected with the corresponding cutting device, wherein one end of a connecting rod of the transmission part is connected with the piston rod of the hydraulic oil cylinder, and the other end of the connecting rod of the transmission part is connected with a cutting frame. Sliding sleeves sleeve sliding rails and are connected with the cutting frames. The slidingrails are obliquely arranged. The sliding sleeves are provided with driving wheels and tensioning wheels. Saw ropes are wound among the driving wheels, the tensioning wheels and driven wheels. The hydraulic power device is arranged on the ground, power is transmitted to an underwater part through hydraulic pipelines, saw rope tensioning and cutting are finished underwater, the executing mechanismpower transmission line is shorter, the energy utilization rate is higher, accordingly, equipment energy consumption is reduced, the equipment price is correspondingly reduced, and installation is more convenient and rapid. Personnel conduct control and monitoring on the ground, and safety is high.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a device for underwater cutting and a cutting method thereof. Background technique [0002] In the traditional underwater obstacle cutting process, the artificial anchor cable cutting scheme is usually used. However, during deep well operations, there are risk sources such as toxic and harmful gases, water gushing and sand gushing, and personnel are in danger of suffocation, poisoning and drowning. Moreover, the anchor cable is in a state of stress tension during the cutting process, and the cut anchor cable may cause personal injury during the removal and tensioning process. Personnel work in the casing, the space is narrow, the operation is restricted, and mechanical injury may occur. In terms of safety, if 24v voltage is used, the choice of equipment is also limited. Due to the dry operation, the cooling of the equipment also requires special consideration....
