Description
Technical field
The present invention relates to a kind of four leg bracing or strutting arrangements of highway barrier breakdown van.
Background technology
At present, after China overwhelming majority highway barriers are broken or damage by vehicle, generally adopt manual method to carry out pile pulling and piling work again.Now, express highway begins progressively to adopt the guardrail breakdown van to play group stake work.And the operation supporting mechanism of the guardrail breakdown van that generally uses generally adopts screw mandrel formula M/C, and labor strength is big, inefficiency.Another kind of guardrail breakdown van adopts the hydraulic ram structure, utilize stretching out of oil cylinder, direct contact ground, M/C is compared in this hydraulic control operation, and labor strength reduces relatively, but when playing the pile pulling operation, the impact of hydraulic hammer is shaken by force, the ground-surface oil cylinder of vertical support is swung, very easily caused the torsional deflection of oil cylinder, reduce the service life of oil cylinder.What is more important after having played a guardrail stake, when moving to the operation of next stake position, is beaten the pile pulling device and will be regained expansion more again, has reduced work efficiency, is difficult to be suitable for the needs of present stage express highway routine servicing.
Summary of the invention
The purpose of this invention is to provide a kind of employing hydraulic control device, eight support rollers of four legs of highway barrier breakdown van are all contacted with ground, guarantee the safety of piling and pile pulling, closely support roller needn't be packed up during moving vehicle, improved the work efficiency of piling and pile pulling, used and four leg bracing or strutting arrangements of easy to operate highway barrier breakdown van.
For achieving the above object, a kind of four leg bracing or strutting arrangements of highway barrier breakdown van, comprise girder two ends each fix a bearing, the bearing in left side flexibly connects the upper end of jib, the stub of the lower end of jib in bearing seat is connected turning rolls with bearing, turning rolls and roller flexibly connect, and in the inner chamber of a turning rolls a plurality of rollers are installed; One end of oil cylinder is hinged on the middle part of jib, and the other end of oil cylinder and the bearing on right side are hinged.
In order to realize products perfection, improve, improve Combination property of the present invention, further step is:
The flexible connection of described turning rolls and roller is: the axis both sides of roller are sleeved in the plain bearing, and the outer wall of plain bearing is inlayed in the bearing carrier ring that is enclosed within on the turning rolls.
The two sides at described jib middle part are provided with through hole, and oil cylinder one end inserts in the through hole and flexibly connects with jib.
The present invention adopt girder two ends each fix a bearing, the bearing in left side flexibly connects the upper end of jib, stub and the bearing of the lower end of jib in bearing seat flexibly connects turning rolls, and turning rolls and roller flexibly connect, and in the inner chamber of a turning rolls a plurality of rollers are installed; At an end of the hinged oil cylinder in the middle part of jib, the other end of oil cylinder and the bearing on right side are hinged.The flexible connection of turning rolls and roller is: the axis both sides of roller are sleeved in the plain bearing, and plain bearing is inlayed in the bearing carrier ring that is enclosed within on the turning rolls.The two sides at jib middle part are provided with through hole, and oil cylinder one end inserts the scheme that flexibly connects with jib in the through hole, and it is big to have overcome existing screw mandrel formula M/C labour intensity, and oil cylinder supports the very easily defective of torsional deflection.
The beneficial effect that the present invention is produced compared to existing technology:
1, use hydraulic control device, make the highway barrier breakdown van when work, eight support rollers of four legs all compressing support the weight of car body on the ground, guaranteed piling, dialled the safety of stake.
2, the highway barrier breakdown van at work, when car load was closely mobile, the roller that four legs support needn't be packed up, and has improved the work efficiency of piling and pile pulling.
3, simple and reasonable, compact, low cost of manufacture.
4, use and operate by fluid control, the operator does not need to bear manual labor again.
The present invention is applicable to other vehicle of highway barrier breakdown van and similar structures.
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Description of drawings
Fig. 1 is an assembling front view of the present invention.
Fig. 2 is Fig. 1 left view.
Fig. 3 is the assembly drowing of roller.
Among the figure: 1, girder, 2, bearing, 3, jib, 4, turning rolls, 5, roller, 6, oil cylinder, 7, through hole, 8, bearing seat, 9, plain bearing, 10, bearing, 11, stub, 12, axis.
The specific embodiment
By accompanying drawing Fig. 1, Fig. 2, shown in Figure 3, a kind of four leg bracing or strutting arrangements of highway barrier breakdown van, comprise girder 1 two ends each fix a bearing 2, the bearing in left side 2 flexibly connects the upper end of jibs 3, stub 11 and the bearing 10 flexible connection turning rollss 4 of the lower end of jib 3 through bearing seat 8 in, turning rolls 4 flexibly connects with roller 5, and in the inner chamber of a turning rolls 4 a plurality of rollers 5 is installed; One end of oil cylinder 6 is hinged on the middle part of jib 3, and the other end of oil cylinder 6 and the bearing on right side 2 are hinged; Turning rolls 4 with the flexible connection of roller 5 is: axis 12 both sides of roller 5 are sleeved in the plain bearing 9, and plain bearing 9 is inlayed in the bearing carrier ring 13 that is enclosed within on the turning rolls 4; The two sides at jib 3 middle parts are provided with through hole 7, and oil cylinder 6 one ends insert in the through hole 7 and flexibly connect with jib 3.Bearing cap shim has been installed at the two ends of bearing seat 8, and bearing cap shim has been installed in the end of diaxon bearing sleeve 13.
During use, Hydraulic Pump flows to oil cylinder 6 with pressure oil, oil cylinder 6 work, when the highway barrier breakdown van is worked, after the highway barrier breakdown van is parked in control position, the rod end of oil cylinder 6 stretches out, the swing of jib 3 cws, and jib 3 is upright gradually, roller 5 moves, the weight of highway barrier breakdown van is transferred on 8 rollers 5 below 4 jibs 3, the tire of highway barrier breakdown van is not stressed, this moment, the work of piling and pile pulling just can begin, at work, oil cylinder 6 keeps hydraulic pressure constant, and the rod end of oil cylinder 6 is motionless, the invariant position of jib 3.When needs are cut to nearby, only need bleed off the hydraulic oil in the oil cylinder 6, oil cylinder 6 does not have the pressure effect, when starting the highway barrier breakdown van, jib 3 is swung backward, and the highway barrier breakdown van drives 8 rollers 5 and advances, to the new nearby piling or the control position of pile pulling.Because the roller that four legs support is not packed up, and has improved the work efficiency of piling and pile pulling.The present invention is a leg bracing or strutting arrangement in four identical leg bracing or strutting arrangements of highway barrier breakdown van, and plain bearing 9 can change into antifriction-bearing box, and bearing 10 both can be plain bearing and also can be antifriction-bearing box.
