Description
Technical field
The utility model relates to bridge construction facility field, relates in particular to a kind of road and bridge safety guard.
Background technology
Along with expanding economy, also prosperity day by day of carrier, in order to pursue the maximization of interests, the transportation drivers can not loaded in strict accordance with the tonnage of vehicle usually, often all can overload transportation, cause fatal destruction to road and bridge, especially at the bridge of some load-bearing tonnage less, the deadweight tonnage of lorry is considerably beyond the load-bearing tonnage of bridge, overload also can road pavement cause damage simultaneously, cause serious economic loss to country, also affect normal communications and transportation simultaneously, need the annual a large amount of manpower and materials of input that need to be keeped in repair.
Summary of the invention
The utility model is for the deficiency existed in background technology, and a kind of road and bridge safety guard provided.
Road and bridge safety guard of the present utility model; to be formed by lifting railing and control device; its described control device for being equipped with pressure plare on fixed head; uniform more than one spring assembly between fixed head and pressure plare; all be fixed wtih spacing cylinder on the internal pressure plate of each spring assembly; the lifting railing that one end of fixed head is provided with drive link and its sidepiece is in transmission connection; be provided with inclined-plane driving member in opposite directions between described pressure plare and drive link, when spacing cylinder contacts with fixed head, the inclined-plane driving member starts.
Road and bridge safety guard of the present utility model, the both sides of described pressure plare are equipped with domatic.
A kind of road and bridge safety guard of the present utility model, simple in structure, convenient and practical, applied widely, mobile flexibly; be not subject to the restriction in place, it is convenient to install, and cost is low; be conducive to extensively promote the use of the destruction of effectively having avoided overloaded vehicle by bridge, it to be caused.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with 1 pair of a kind of road and bridge safety guard of the present utility model of accompanying drawing, elaborate.
The road and bridge safety guard that this practicality is novel, to be formed by lifting railing 1 and control device 2, its described control device 2 for being equipped with pressure plare 4 on fixed head 3, uniform more than one spring assembly 5 between fixed head 3 and pressure plare 4, all be fixed wtih spacing cylinder 6 on the internal pressure plate 4 of each spring assembly 5, one end of fixed head 3 is provided with drive link 7 and is in transmission connection with the lifting railing 1 of its sidepiece, be provided with inclined-plane driving member 8 in opposite directions between described pressure plare 4 and drive link 7, when spacing cylinder 6 contacts with fixed head 3, inclined-plane driving member 8 starts, the both sides of described pressure plare 4 are equipped with domatic 9.
The road and bridge safety guard that this practicality is novel; under peacetime state, lifting railing 1 is open mode; spring assembly 5 and spacing cylinder 6 are set the carrying tonnage of pontics; when when spring assembly is compressed, spacing cylinder 6 contacts with fixed head 3, it is the carrying tonnage of target pontic; thereby the vehicle that surpasses tonnage falls lifting railing 1 by the equal inclined-plane driving member 8 contact starts drive drive links 7 that can make; stop vehicle to pass through; tonnage with interior vehicle by the time inclined-plane driving member 8 do not start, lifting railing 1 still is held open state.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrate, and is not only.All in the utility model scope or the change be equal in scope of the present utility model all be included in the utility model.
