Abstract
The utility model provides a hydraulic roadblock machine with high bearing and strong collision prevention capacity, which comprises a hydraulic pump station and an executive device. The executive device comprises a frame, a cover board and a driving device. The cover board and the frame are in movable connection. The driving device is used for driving the cover board to rise or descend. The lower part of the cover board is fixedly provided with a plurality of support beams. When the cover board is in the descending closing state, the support beams are in contact with the frame. The support beams are fixedly provided with limit seats. When the cover board is in the rising open state, the limit seats are laminated with a cross beam on the frame. The utility model designs the cover board into a self-supporting structure and has small span, good rigidity and greatly strong bearing capability. The collision prevention structure directly consists of the limit seats on the cover board and the cross beam on the frame and has high strength, more stress points and strong collision prevention capacity. Moreover, the hydraulic roadblock machine cancels the existing four-bar mechanism, adopts a hydraulic oil cylinder to directly push the cover board and has simpler structure and more stable and reliable driving.
Description
Technical field
The utility model relates to a kind of high-bearing and the strong hydraulic pressure roadblock machine of crashproof ability.
Background technology
At present, the carrying of the cover plate of existing hydraulic pressure roadblock machine is by the both sides frame support, and middle part span broad causes supporting capacity poor, and yielding; Its crashproof ability guarantees by four-bar mechanism, because many cover four-bar mechanisms are very high to technological requirement, a cover four-bar mechanism is only arranged generally, causes stress point too concentrated, thereby crashproof limited in one's ability, and is yielding when being hit.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of high-bearing and crashproof ability strong hydraulic pressure roadblock machine.
The utility model is to realize like this, a kind of hydraulic pressure roadblock machine, comprise hydraulic power unit and actuating unit, described actuating unit comprises frame, cover plate and drive unit, flexibly connect between described cover plate and the frame, described drive unit is used to drive described cover plate and rises or fall, and described cover plate below is installed with some brace summers, and described brace summer is in when falling closure state in described cover plate and contacts with described frame; Be installed with limit base on the described brace summer, the crossbeam applying of described limit base when described cover plate is in the rise open mode and on the described frame.
Particularly, hinged between described cover plate and the frame by first bearing pin.
Particularly, described drive unit is a hydraulic cylinder, and described hydraulic cylinder one end and described frame flexibly connect, and the other end and described cover plate flexibly connect.
More specifically, described hydraulic cylinder one end is hinged by second bearing pin and described frame, and the other end is hinged by the 3rd bearing pin and described cover plate.
Particularly, welding is fixing between described brace summer and the limit base.
The utility model is designed to self supporting structure with cover plate, and span is little, good rigidly, supporting capacity are extremely strong; Anti-collision structure directly is made up of limit base on the cover plate and the crossbeam on the frame, the intensity height, and stress point is many, and crashproof ability is strong; In addition, the utility model has been cancelled existing four-bar mechanism, adopts the direct knock-out pad of hydraulic jack, and structure is simpler, driving is more reliable and more stable.

Fig. 2 is the floor map under the open mode of the hydraulic pressure roadblock machine that provides of the utility model embodiment;
Fig. 3 is the schematic perspective view under the open mode of the hydraulic pressure roadblock machine that provides of the utility model embodiment.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As Fig. 1～shown in Figure 3, a kind of hydraulic pressure roadblock machine that the utility model embodiment provides, comprise hydraulic power unit (not shown) and actuating unit 1, described actuating unit 1 comprises frame 11, cover plate 12 and drive unit 13, flexibly connect between described cover plate 11 and the frame 12, described drive unit 13 is used to drive described cover plate 12 rises or falls, described cover plate 12 belows are installed with some brace summers 121, the concrete quantity of brace summer 121 can be decided according to the carrying size and the size of cover plate 12, and present embodiment adopts 5 brace summers 121; Described cover plate 12 is in when falling closure state, and described brace summer 121 contacts with described frame 11, supports because of a plurality of brace summers 121 are arranged, and span is little, good rigidly, supporting capacity are extremely strong; Be installed with a limit base 122 on the described brace summer 121; described cover plate 12 is in when rising open mode; described limit base 122 is fitted with the crossbeam 111 on the described frame 11; because of the intensity of limit base 122 very high; and be furnished with a plurality of (present embodiment is 5 limit bases 122); therefore; no matter cover plate 12 which part are impacted; cover plate 12 can both well be resisted impact; can be subjected to good protection; can not occur as existing roadblock machine anti-collision structure far away because of two ends from four-bar mechanism, the phenomenon of the yielding damage of cover plate when being hit.
Particularly, hinged by first bearing pin 14 between described cover plate 12 and the frame 11, under the driving of drive unit 13, cover plate 12 can rotate up and down by this first bearing pin 14.
Particularly, described drive unit 13 is a hydraulic cylinder 131, and described hydraulic cylinder 131 1 ends and frame 11 flexibly connect, the other end and cover plate 12 flexibly connect, more specifically, described hydraulic cylinder 131 1 ends are hinged with frame 11 by second bearing pin 15, and the other end is hinged with cover plate 12 by the 3rd bearing pin 16.The utility model adopts hydraulic cylinder 131 to replace existing four-bar mechanism, and structure is simpler, driving is more reliable and more stable.
In addition, the oscillating bearing (not shown) of hinge arrangement of the present utility model changed into and being installed on the fixed hinge seat by being installed on the hinges seat originally, effectively saved installing space, the oscillating bearing internal diameter increases 60%, and the impact resistance of bearing has also increased one times.
Particularly, welding is fixed between described brace summer 121 and the limit base 122, thereby has guaranteed bonding strength between brace summer 121 and the limit base 122, has improved the impact resistance of cover plate 12.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
