Description
Technical field
The utility model relates to a kind of bridge height limiter.
Background technology
The running section of highway is crossed at bridge and railway, due to the limited height of bridge, capital arranges a height limiter, and the height prompting that mark restriction is current, but in actual motion, run into transport big machinery when needing to pass through, a lot of height limiter is owing to cannot change height, usually be removed, eliminate and abandon, cause waste.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, provides a kind of bridge height limiter.
Described object is achieved by the following scheme: a kind of bridge height limiter, comprise two root posts of pre-buried underground, the top of described column is connected with standpipe by flange, bottom in described standpipe is provided with hydraulic cylinder, the top of described hydraulic cylinder is provided with vertical rod, the top of two vertical rods is hinged with crossbeam by rotating shaft, and the tube wall of described lower riser end is provided with square aperture.
The edge of described opening has enabling by gemel connection.
The utility model has the following advantages: the utility model can control the height of vertical rod by hydraulic cylinder, run into transport big machinery need by time, without the need to the utility model is dismantled.Easy to use, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1-column, 2-flange, 3-standpipe, 4-hydraulic cylinder, 5-vertical rod, 6-rotating shaft, 7-crossbeam, 8-opening.
Detailed description of the invention
The utility model is elaborated preferred embodiment below in conjunction with accompanying drawing.
A kind of bridge height limiter, comprise two root posts 1 of pre-buried underground, the top of described column 1 is connected with standpipe 3 by flange 2, bottom in described standpipe 3 is provided with hydraulic cylinder 4, the top of described hydraulic cylinder 4 is provided with vertical rod 5, the top of two vertical rods 5 is hinged with crossbeam 7 by rotating shaft 6, and the tube wall of described standpipe 3 lower end is provided with square aperture 8.The edge of described opening 8 has enabling by gemel connection.
Hydraulic cylinder 4 is fixed on the bottom in standpipe 3 by opening, the outside that the top of vertical rod 5 extends to standpipe 3 is connected with horizontal 7 beams by rotating shaft 6, and press the hydraulic pressure pedal on hydraulic cylinder 4, the piston rod in hydraulic cylinder 4 is by vertical rod jack-up.The design that vertical rod 5 top is connected with crossbeam 7 by rotating shaft 6, when being in order to both sides vertical rod 5 landing simultaneously, during owing to rising or falling after rise, the height tolerance of manual control, avoids vertical rod 5 to be stuck in the port of standpipe 3.
Present embodiment does not just limit its protection domain to the exemplary illustrated of this patent; those skilled in the art can also carry out local to it and change; as long as no the Spirit Essence exceeding this patent, be all considered as the equivalent replacement to this patent, all at the protection domain of this patent.
