Description

Hydraulic pressure roadblock machine

The utility model belongs to a kind of roadblock machine that control vehicles such as road, parking lot are come in and gone out that is used for.

Dash the pass in order to stop vehicle, make the more convenient safety of road management and parking lot management to be provided with the roadblock machine at the critical point of road or the place, access in parking lot usually.Existing hydraulic pressure roadblock machine, its hydraulic cylinder generally is directly installed on the base, and the push rod of hydraulic cylinder uprightly promotes cover plate, and the push rod stroke is long, and power consumption is big, the device quick abrasion, the life-span is short.

The purpose of this utility model is: a kind of novel hydraulic roadblock machine is provided, and it is short to have a push rod stroke, and power consumption is little, install not easy to wear, the advantage that the life-span is grown.

The technical solution of the utility model is: a kind of hydraulic pressure roadblock machine, comprise hydraulic power unit and actuating unit, and described actuating unit comprises frame, cover plate and hydraulic cylinder, it is characterized in that, described actuating unit also comprises support bar and rocking bar; Described hydraulic cylinder is fixed on free bearing on the support of frame sidepiece, and the end of the push rod of hydraulic cylinder is connected in the middle and lower part of described rocking bar with bearing iron hinge, and the lower end of rocking bar is fixed on the frame with bearing iron hinge; The two ends of described support bar are connected on the upper end and cover plate of described rocking bar by bearing iron hinge; Described hydraulic cylinder is connected with described hydraulic power unit with oil pipe.

Aforesaid the utility model hydraulic pressure roadblock machine, hydraulic cylinder is located at the sidepiece of frame, and the leverage mechanism that forms by push rod, rocking bar and support bar is to the thrust and the pulling force of cover plate transmission fluid cylinder pressure, the little stroke of push rod can be converted into the big stroke of cover plate, make that executing agency's power consumption is little, install not easy to wearly, the life-span greatly prolongs.

Below by drawings and Examples the utility model is further specified.

Above-mentioned accompanying drawing has provided an exemplary embodiments of the utility model hydraulic pressure roadblock machine, and it is made up of hydraulic power unit and actuating unit two large divisions, and wherein Fig. 1 and Fig. 2 show the structure and the duty of operating part driving mechanism.The driving mechanism of actuating unit comprises frame 20, cover plate 21, hydraulic cylinder 18, support bar 16 and rocking bar 17; Hydraulic cylinder 18 usefulness free bearings are fixed on the support 19 of frame 20 sidepieces, and the end of the push rod 24 of hydraulic cylinder 18 is connected in the middle and lower part of rocking bar 17 with bearing iron hinge, and the lower end of rocking bar 17 is fixed on the frame 20 with bearing iron hinge; The two ends of support bar 16 are connected on the upper end and cover plate 21 of rocking bar 17 by bearing iron hinge; Hydraulic cylinder 18 is connected with hydraulic power unit with oil pipe.The push rod 24 of hydraulic cylinder 18 is supported in the middle and lower part of rocking bar 17, makes push rod 24 little strokes produce bigger lift angle in the upper end of rocking bar 17, has the advantage of little stroke great-lift angle.When cover plate 21 was in the rising extreme position, the angle of rocking bar 17 and support bar 16 was less than 180 degree, and not exclusively self-locking can fall cover plate 21 after rise with hand-operated valve 11 releases when power failure or other fault take place like this.

As shown in Figure 3, actuating unit also is provided with balanced controls in the present embodiment, and these balanced controls comprise support bar 16, balanced connecting rod 25, sleeve 23, preloading spring 31 and elevating lever 22; Sleeve 23 is connected on the frame 20 by free bearing, and spring base 33 and elevating lever 22 are connected in one by welding manner, and can move up and down in sleeve 23; The lower end of preloading spring 31 is positioned at spring base 33, between preloading spring 31 and the spring base 33 cushion pad 32 is arranged, and the upper end of this preloading spring 31 is positioned at the top cover 30 of sleeve 23, and top cover 30 and sleeve 23 link into an integrated entity; The right-hand member of balanced connecting rod 25 is connected on the elevating lever 22 with bearing iron hinge, and the middle right part of this balanced connecting rod 25 is connected on the frame 20 with bearing iron hinge; The two ends of support bar 16 are connected in by bearing iron hinge on the left end and cover plate 21 of balanced connecting rod 25, form a leverage mechanism of playing balanced action.

The hydraulic pressure roadblock facility that are provided with balanced controls have motion steadily, the advantage that toggle speed is fast.The preloading spring 31 of balanced controls is compressive state when cover plate 21 is in original state, make the support force that makes progress of balanced controls and the gravity of cover plate 21 equate, when the push rod 24 of hydraulic cylinder 18 was started working, active force promoted cover plate 21 immediately and moves upward, and has shortened start-up time.In the motion process that cover plate 21 makes progress, preloading spring 31 progressively discharges, and the gravitational moment of cover plate 21 also gradually reduces, but in whole process, the moment that preloading spring power the forms gravitational moment with cover plate 21 all the time is equal, and system has good balance, operate steadily, the power of consumption is little.

As shown in Figure 4, in the present embodiment hydraulic pressure roadblock machine hydraulic power unit comprise that motor 1, pump mount pad 2, fuel tank pull 3, shaft coupling 4, vane pump 5, fuel sucking pipe 6, filter core 7, cabinet 8, valve connected body 9, adjustable throttling 10, hand-operated valve 11, electromagnetic valve 12, oil meter component 13, overflow valve 14 and flowline 15; Motor 1 is fixed on the fuel tank plate 3 by pump mount pad 2, motor 1 and vane pump 5 connect by shaft coupling 4, fuel sucking pipe 6 connects vane pump 5 and filter core 7, flowline 15 connects the oil-out of vane pump 5 and the oil-in of valve connected body 9, overflow valve 14, electromagnetic valve 12, choke valve 10, hand-operated valve 11 and oil meter component 13 all are installed on the relevant position of valve connected body 9, are connected by the oil circuit of valve connected body 9 inside.In hydraulic power unit, adopted overflow valve 14 and adjustable throttling 10, the hydraulic working oil pressure stability, the reliable working performance of native system is stable.
