Abstract
The utility model discloses a vehicle-mounted workover rig. The utility model is composed of a derrick, an automobile chassis and an auxiliary frame, wherein, the auxiliary frame is fixed on the automobile chassis by a screw bolt; a front bracket, a back bracket, a derrick lifting oil cylinder and a support oil cylinder are arranged on the auxiliary frame; the derrick is arranged on the front and the back brackets; a special power unit is arranged on the auxiliary frame; the back of the power unit is connected with a transmission system; the back of the transmission system is connected with the derrick lifting oil cylinder and a winch. The utility model has the advantages of low cost, long service life, etc.
Description
The utility model relates to a kind of workover rig, belongs to the vehicular equipment that in the oil exploitation process oil, well is carried out workover treatment.
Existing vehicular workover rig is to utilize the power selection case respectively main car engine to be delivered to the running gear of special-purpose workover rig equipment part and automobile chassis on workover rig chassis special or body with frame, special-purpose well-repairing work device by the power selection case with transmission of power to the angie type transmission case, on the work packages such as winch, special-purpose well-repairing work device and the shared power unit of chassis running gear and gearbox and power selection case, thereby it is inhomogeneous to have caused the each several part member to wear and tear in the course of the work, fault rate is higher and have influence on the rate of attendance of vehicle, and the cost of this workover rig is very high, is unfavorable for applying.
The purpose of this utility model is exactly the shortcoming that overcomes prior art, the vehicular workover rig that provides the special-purpose equipment of a kind of well workover and chassis running gear engine, gearbox to separate.
The purpose of this utility model is achieved in that it is made up of derrick, automobile chassis, subframe, subframe is by being bolted on the automobile chassis, fore-stock, after-poppet, derrick lift oil tank and support oil cylinder are housed on subframe, on forward and backward support, derrick is housed, on subframe, be provided with the spcific power unit, connect transmission system behind the power unit, connect derrick lift oil tank and winch after the transmission system.
Transmission system is made up of clutch, bearing support, universal drive shaft, gearbox, bearing support is fixed on the subframe, clutch base is on bearing support, the clutch front end links to each other with the power unit, the rear end joins by universal drive shaft and gearbox, between gearbox and the winch also by the universal drive shaft transmission.
Another kind of transmission scheme is that gearbox is connected and transferring power with chain coupling with bearing support, adopts chain drive between gearbox and the winch.
The utility model is because with the special-purpose equipment of well workover and chassis running gear engine, gearbox separately, and adopts a large amount of general parts, thereby reduced the cost of complete machine, reduced the wearing and tearing of parts, improved the rate of attendance of equipment.Prolonged the application life of workover rig.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1: vehicular workover rig structural representation;
Fig. 2: first kind of kinematic scheme;
Fig. 3: second kind of kinematic scheme;
Among the figure: 1-derrick, 2-automobile chassis, 3-fore-stock, 4-spcific power unit, 5-transmission system, 6-derrick lift oil tank, 7-winch, 8-control stick, 9-after-poppet, 10-support oil cylinder, 11-subframe, 12-clutch, 13-bearing support, 14-universal drive shaft, 15-gearbox, 16-chain coupling, 17-driving chain;
As shown in Figure 1, the vehicular workover rig is made up of derrick 1, automobile chassis 2, subframe 11, subframe 11 is by being bolted on the automobile chassis 2, fore-stock 3, after-poppet 9, derrick lift oil tank 6 and support oil cylinder 10 are housed on subframe 11, derrick 1 is housed on forward and backward support, on subframe 11, be provided with spcific power unit 4, connect transmission system 5 behind the power unit, connect derrick lift oil tank 6 and winch 7 after the transmission system 5.As shown in Figure 2, transmission system 5 can adopt dual mode, a kind ofly form by clutch 12, bearing support 13, universal drive shaft 14, gearbox 15, bearing support 13 is fixed on the subframe 11,12 on clutch is on bearing support 13, clutch 12 front ends link to each other with power unit 4, and the rear end joins by universal drive shaft 14 and gearbox 15, between gearbox 15 and the winch 7 also by universal drive shaft 14 transmissions.Another kind of transmission scheme as shown in Figure 3, transmission system 5 is made up of clutch 12, bearing support 13, gearbox 15, chain coupling 16, clutch 12 front ends link to each other with power unit 4, the rear end is connected with gearbox 15 by chain coupling 16, between gearbox 15 and winch 7 by driving chain 17 transmissions.
During work, the vehicular workover rig is reached the position that will carry out well in operation to stop, main car engine is flame-out, pull on the hand brake, accomplish fluently ground anchor pit as requested, the lumps of wood on pad below the support oil cylinder, start spcific power machine idle running then, after air pressure reaches 0.5MPa, hang and close hydraulic oil pump, play supporting leg and rise derrick.Utilize control stick to select the gear of gearbox again, extension closes the engine clutch and can begin workover treatment.
