Description
Technical field
The present invention relates to technical field of engineering machinery, particularly a kind of barrier clearing device of fire fighting truck and fire fighting truck.
Background technology
Along with improving constantly of people's living standard, the number of private car is more and more, this just causes passageway for fire apparatus, part community and residential building room downstairs often to be taken by private vehicle, in the time that fire occurs, fire fighting truck can not break the barriers in time and arrive fire-fighting place, cause the intensity of a fire to be controlled in time, thereby cause unnecessary tragedy to occur.
Fire fighting truck of the prior art mainly has fire-extinguishing function concurrently, in the time running into obstacle vehicle, can only rely on that car owner is conscious removes car, or by manually vehicle being removed, but these move modes are uncontrollable or waste time and energy.
Summary of the invention
The invention provides a kind of barrier clearing device and fire fighting truck of fire fighting truck, be convenient to the barrier in its travel direction to remove, in order to improve the operating efficiency of fire fighting truck.
For achieving the above object, the invention provides following technical scheme.
The barrier clearing device that the invention provides a kind of fire fighting truck, comprising:
Be installed on the base of the vehicle bottom of fire fighting truck, thereby described base and described vehicle bottom can be connected stretching motion can be with respect to described vehicle bottom the short transverse stretching motion along fire fighting truck, with make described barrier clearing device can contact with ground remove obstacles duty and and the rounding state that contacts of vehicle bottom between switch;
Be connected and be convexly set in the bracing frame of car body one side of described fire fighting truck with described base; And
Be installed on the yoke of support frame as described above, on described yoke, yoke be installed.
When barrier clearing device on fire fighting truck provided by the invention uses together with fire fighting truck, in the time running into fire alarm early warning, operating personnel can remove the barrier in fire fighting truck travel direction by controlling barrier clearing device, barrier clearing device can be fixed on the anterior of fire fighting truck or make dismountable structure the front portion that is arranged on fire fighting truck, also can fix (or make dismountable structure and install) sidepiece or afterbody at fire fighting truck, when fire fighting truck travels front while having barrier, barrier clearing device is arranged on the front portion of fire fighting truck, barrier clearing device transfers the duty of removing obstacles contacting with ground to, yoke can be inserted barrier, barrier is lifted away from ground, by the variation of hosebody's direction, barrier can be placed on outside fire fighting truck travel direction.
Visible, the barrier clearing device of fire fighting truck provided by the invention, is convenient to the barrier in its travel direction to remove, in order to improve the operating efficiency of fire fighting truck.
In some optional embodiments, support frame as described above comprises: be installed on the first bracing frame of described base and be installed on the second bracing frame of described the first bracing frame, described yoke is installed on described the second bracing frame, and described the second bracing frame can move along the width of described the first bracing frame.Sometimes the size of barrier may be larger, the length of yoke long enough not again, yoke can not remove barrier the travel direction of fire fighting truck, now, can pass through the slip of the second bracing frame on the first bracing frame width, yoke has been inserted after barrier, and barrier can be as far as possible away from fire fighting truck.
In some optional embodiments, described the first bracing frame comprises: two expansion links that are oppositely arranged and be connected at least one tooth bar between two described expansion links, described the second bracing frame is set in described tooth bar, and described the second bracing frame is provided with the tooth engaging with described tooth bar, described the second bracing frame can carry over the motion of described tooth bar and move along the width of described the first bracing frame, the scalable motion of described expansion link and drive described the second bracing frame to move relative to the short transverse of described fire fighting truck.For the ease of the second bracing frame along the stable slip of the first bracing frame, the number of tooth bar can be two, and two tooth bars be arranged in parallel, driving the drive unit that the second bracing frame moves can be external drive unit, also can be the drive unit of fire fighting truck itself, barrier is lifted away from ground, can realize by the elongation of expansion link.
In some optional embodiments, described two expansion links are respectively a telescoping cylinder, and the relatively described base of the cylinder body of each described telescoping cylinder is fixed, one end of each described tooth bar is connected with the piston rod of telescoping cylinder described in, the other end is connected with the piston rod of telescoping cylinder described in another.
