Abstract
The utility model relates to a workover rig used for an oil field, namely a single-drum drilling and workover rig, which comprises a vehicle-mounted winch and a winch braking mechanism. The winch braking mechanism comprises a balanced system, a brake crank rotating shaft assembly, a connecting rod assembly and a brake band, wherein the connecting rod assembly is connected between the brake band and the brake crank rotating shaft assembly. A power-assisted oil cylinder is connected in the middle of the connecting rod assembly; the power-assisted oil cylinder comprises an oil cylinder body, a piston in the oil cylinder body and a connecting rod penetrating two ends of the oil cylinder body and connected with the piston; and the oil cylinder body is provided with an oil inlet and an oil outlet. The winch braking mechanism adds the braking function of the power-assisted oil cylinder, oil drives the piston in the power-assisted oil cylinder to perform reciprocating motion through the oil inlet and the oil outlet, to add external auxiliary force to releasing and tightening of a brake, the operation is simple, flexible, reliable and labor-saving, and the purpose of reducing the working strength of a driller is achieved.
Description
Technical field
The utility model relates to a kind of oil field workover rig, promptly single cylinder drilling and workover machines.
Background technology
In the prior art, single cylinder drilling and workover machines is the oilfield special equipment, it mainly by steyr two class chassis, vehicle-mounted transfer case, fluid torque-converter, gearbox, winch, derrick, hook block, hydraulic system, air-channel system, electrical system or the like arranged.The complete machine chassis is 6 * 4 steyr chassis, adopts hydraulic power-assisted steering, tack dual chamber.The chassis is provided with between wheel and differential locking between bridge, and all control operations on chassis concentrate in the driver's cabin.The power of motor is passed to vehicular operation part and chassis running gear through transfer case with power.Transfer case reaches gearbox through power transmission shaft, torque-converters shaft coupling, reaches the drum clutch index drum through chain and realizes promoting operation.40 tons of single cylinder drilling and workover machines of THS5253TXJ3 type that my company produces design specified hook and carry 400kN, max. hook load 675kN, be applicable to oil, the well light maintenance operation of 73mm oil pipe (2-7/8 " external upset tubing) 3200m well depth, the heavy repair task of 2000m oil, well.Winch is the core component of workover rig, and its effect is to be used for, to have bored down and setting of casing.It partly is made up of roller assembly, winch bed, braking mechanism, chain guard, clutch cover, roller chain etc.Input links to each other with gear box output end through chain drive, and output links to each other with hook block by the hoist rope that twines on cylinder.Braking mechanism mainly is made up of pitman shaft, balance sysmte, brake lever assembly, connecting rod ASSY, brake strap assembly etc.Its shortcoming is a relatively effort of single cylinder drilling and workover machines brake, and driller's working strength is big.
The utility model content
The purpose of this utility model is to provide a kind of brake labour-saving single cylinder drilling and workover machines at above-mentioned deficiency.
Technical solution of the present utility model is: single cylinder drilling and workover machines comprises vehicle-mounted winch, winch brake mechanism; Winch brake mechanism comprises balance sysmte, brake lever rotating shaft assembly, connecting rod ASSY, brake strap composition; Connecting rod ASSY is connected between brake strap and the brake lever rotating shaft assembly.The connecting rod ASSY middle part is connected with the power-assisted oil cylinder, and the power-assisted oil cylinder comprises cylinder body, cylinder body inner carrier, runs through the connecting rod that the cylinder body two ends are connected with piston, and cylinder body is brought into, oil-out.
The utility model has the advantages that: winch brake mechanism has increased power-assisted oil cylinder brake function, the piston that oil drives in the power-assisted oil cylinder by oil-in and oil-out moves back and forth, unclamp and hold tightly and add external auxiliary force to brake, convenient and flexible operation, reliably laborsaving reaches the purpose that has alleviated driller's working strength.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Description of drawings
Fig. 1 is a winch brake mechanism structure sketch in the utility model.
Fig. 2 is a power-assisted cylinder structure sketch.
The specific embodiment
Referring to Fig. 1, single cylinder drilling and workover machines comprises vehicle-mounted winch, winch brake mechanism.Winch brake mechanism comprises pitman shaft 5, balance sysmte 4, brake lever rotating shaft assembly 1, connecting rod ASSY 2, brake strap 6 compositions.Connecting rod ASSY 2 is connected between brake strap 6 and the brake lever rotating shaft assembly 1.Connecting rod ASSY 2 middle parts are connected with power-assisted oil cylinder 3.
Referring to Fig. 2, power-assisted oil cylinder 3 comprises cylinder body 7, and the piston 8 in the cylinder body runs through the connecting rod 9 that cylinder body 7 two ends are connected with piston 8, and cylinder body 7 is brought hydraulic fluid port 10 and oil-out 11 into.The control valve of brake power-assisted cylinder 3 is contained near the brake lever seat, controlling organization is installed on the brake lever handle 12, when handle 12 rotates in the direction of the clock, and the power-assisted cylinder operation, be rotated counterclockwise brake lever handle 12 power-assisted oil cylinders 3 and quit work, lift brake lever then and finish brake.The piston 8 that drives in the power-assisted oil cylinder 3 by oil-in 10 and oil-out 11 of oil moves back and forth, and unclamps and holds tightly and add external auxiliary force to brake.
