Description
One, technical field
The present invention relates to a kind of oil field and repair the tractor hoist that oil-water well is used, especially a kind ofly can repair oil-water well, can realize that again short-term regards oil pumper and use, replace the multifunctional electric well dredger of old-fashioned tractor hoist formation testing.
Two, background technology
Tractor hoist is that the visual plant that oil-water well is used is repaired in the oil field, and existing tractor hoist basically all is that diesel engine is used as power, and walking manner is divided into crawler type and wheeled.Even motor can not be out of service during shackle on operating oil line for this type tractor hoist when work workman, and Efficiency of Diesel Engine is low, fuel is expensive, causes bigger waste; The complex steps when workman operates tractor hoist, labour intensity is big; On carry or transfer the height of pipe during roofbolt and artificially control, in case control excessive very dangerous; Need when having repaired the oil well of acidifying fast the acidifying solution in shaft bottom to be discharged, because oil pumper can't be installed and used, can only use the tractor hoist manually-operated to aspirate up and down, needed continuous operation sometimes more than 30 day, labour intensity is big; Because the running noises of diesel engine is big especially, it is physically and mentally healthy to influence the workman.In order to save energy and reduce the cost, increase work efficiency, to reduce labor strength, improving safety, be badly in need of a kind of tractor hoist that can solve above shortcoming.
Three, summary of the invention
A kind of multifunctional electric well dredger that the objective of the invention is to solve the shortcoming of existing tractor hoist and provide; The reparation that can realize oil-water well puts the pipe bar and short-term is used as oil pumper, and this tractor hoist is simple in structure, and noise is little; Good energy-conserving effect; Operation labour intensity is little, and security performance is high, has overcome the shortcoming of existing tractor hoist effectively.
Technical scheme of the present invention realizes in the following manner:
The present invention includes Crane Truck Chassis, box type transformer, cable drum, operation bench, drive motors, encoder, roller assembly, back band, brake-fluid cylinder pressure, cylinder shaft coupling, reducer, the high low speed conversion of reducer shelves, electricity loss brake, motor coupler, Hydraulic Station, switch board; It is characterized in that the front end on the Crane Truck Chassis is equipped with box type transformer; The place ahead of box type transformer transversely is equipped with cable drum and switch board, and the front of cable drum is equipped with drive motors, roller assembly and Hydraulic Station by preface; Reducer and operation bench are installed by preface in the front of switch board; On the output shaft of drive motors motor coupler is installed, the other end of motor coupler is connected on the input shaft of speed reducer, and the input shaft of speed reducer other end is equipped with electricity loss brake; High low speed conversion shelves are installed in the casing of reducer; The output shaft of reducer is connected to through the cylinder shaft coupling on the main shaft of roller assembly, and the middle part of roller assembly is a wire rope drum, and the two ends of wire rope drum are brake rims; The outside of brake rim is equipped with back band; One end of back band is fixed on the base of roller assembly, and the other end is fixed in the rotating shaft, and one side is equipped with the brake-fluid cylinder pressure in the bottom of wire rope drum; One end of brake-fluid cylinder pressure is fixed on the base of roller assembly, and the other end is connected in the rotating shaft.
