Abstract
The utility model relates to an oil field workover rig, and in particular to a self-travelling anchor rope-free workover rig which is suitable for oil field minor workover operation. The self-travelling anchor rope-free workover rig comprises an automobile chassis, wherein a winch, an upper derrick body, a lower derrick body, a derrick rear support, a derrick crown and flexible support jacks which are arranged on the front part and the rear part of the automobile chassis are arranged on the automobile chassis. A rear large leg of the lower derrick body is respectively connected with a triangular support rear large leg and the rear support through hinged fulcrums, and after the lower derrick body is erected in position, a front large leg of the lower derrick body is located on a triangular support front large leg. The bending resistance can be improved, the rigidity can be enhanced, and the stability of a derrick is increased. The elastic support jack on the rear part of the automobile chassis is distributed along a splayed direction, an elastic beam has two sections, so that the extension length of the single jack is increased within a limit width, and the vehicle bearing stability is improved. Through improving the whole derrick structure and the elastic jack structure and distribution and moving the vehicle bearing gravity center, the integral performance and stability of the workover rig are greatly improved, guarantee is provided for removing anchor rope fixing, and the large-tonnage anchor rope-free workover rig can be realized.
Description
Technical field
The utility model relates to a kind of oil well equipment, and namely applicable oil field light maintenance operation walks certainly without anchor rope workover rig.
Background technology
In the prior art, as the oilfield special equipment, general workover rig all is to be assembled on the general two class automobile chassises.This shortcoming of repairing the machine machine is: 1, the supporting capacity of chassis vehicle is little, and tire is restricted, and workover rig is strict to well site of oil field and travel, has limited the weight on the well workover board.2, in conventional workover treatment, after workover rig derrick is propped, for stability and safety, derrick will be tightened with four jiaos earth anchor around four outer guy wires and the operation field and be connected, because beating outer guy wire relatively wastes time and energy, some well site is subjected to the landform restriction can't beat outer guy wire simultaneously, so this work of giving brings a lot of problems.Vehicle-mounted stable during 3, for workover treatment, it is very heavy to be provided with transversal stretching at the rear portion, chassis, because collapsing length laterally on same axis, has been limited in two very heavy edges of transversal stretching.4, be connected to two hinged supports between conventional workover rig after-poppet and the derrick body, the after-poppet side is generally rectangle or antiparallelogram, and is not enough on the flexural strength of bottom.
The utility model content
The purpose of this utility model is to provide a kind of good stability for above-mentioned deficiency, and what result of use improved walks certainly without anchor rope workover rig.
Technical solution of the present utility model is: certainly walk without anchor rope workover rig, comprise automobile chassis, comprise on it that winch, derrick upper body, derrick lower body, derrick after-poppet, derrick crown, automobile chassis front portion, rear portion have retractable support very heavy.Be connected by hinged support between thigh and the after-poppet behind thigh and the tripod behind the derrick lower body, after the derrick lower body erected and puts in place, thigh was sitting in before the tripod on the thigh before the derrick lower body.Can improve flexural strength, strengthen rigidity, increase the stability of derrick.
Automobile chassis rear portion retractable support is very heavy arranges that along the splay configuration direction extensible canopy is binodal.In limited width, increase so single very heavy extension elongation, be conducive to improve vehicle-mounted stability.
Drawn two tension guy wires in the derrick crown bottom, the guy wire other end is connected with chassis frame.
The utility model has the advantages that: 1, chassis load capacity is strong, and trafficability characteristic is good, handles agile work, has satisfied the requirement of loading under the adverse circumstances such as oil field mire and waterlogged lowland band with transportation, is fit to the workover treatment in mire and oil field, beach area.2, by improving derrick overall structure, derrick positioner, flexible very heavy structure and arranging, vehicle-mounted center of gravity is moved forward, workover rig vehicle performance and stability have greatly been improved, for the cancellation guy wire has been fixed with guarantee, so that workover rig has realized that large-tonnage is without guy wire.3, convenient, fast, the safety of Job Operations has reduced labour intensity, has improved operating efficiency.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is derrick working state structure schematic diagram.
Fig. 3 is Fig. 2 left view.
Fig. 4 is that flexible very heavy working face is arranged schematic diagram.
The specific embodiment
Referring to Fig. 1, from walking without anchor rope workover rig to comprise automobile chassis 1, comprise winch 7, derrick upper body 14, derrick lower body 5, derrick after-poppet 15, derrick crown 16, fore-stock 2, motor 3, fluid torque-converter 4, right angle gear box 6, liquid-way system 8, pulpit 9, air-channel system 10, electrical system 11, hook block 12, tripod 13 on it.Tire adopts wide basic giant tyre.Same motor is adopted in automobile chassis 1 walking and operation.
Referring to Fig. 1,2,3, be connected by two hinged supports between derrick lower body 5 rear thighs and tripod 13 rear thighs and the derrick after-poppet 15, after derrick lower body 5 erected and puts in place, derrick lower body 5 front thighs were sitting on the tripod 13 front thighs.Two tension guy wires 19 have been drawn in derrick crown 16 bottoms, and guy wire 19 other ends are connected with chassis frame, when hanging load derrick are played the safeguard protection effect.
Referring to Fig. 4, automobile chassis 1 rear portion retractable support very heavy 17 arranges that along the splay configuration direction extensible canopy is binodal.Automobile chassis 1 front portion has front stretching to support very heavy 18.
This structure is particularly useful for from walking without 60 tons of workover rigs of guy wire.
