Road block removal device of fire engine

Abstract

The invention relates to a road block removal device of a fire engine, which belongs to the technical field of special vehicles. The road block removal device of the fire engine comprises a pair of crossbeams of a chassis frame. The road block removal device comprises a bracket, an upper connecting rod rack, a lower connecting rod rack, a shoveling plate seat, a main shoveling plate and a pair of acting cylinders, wherein the bracket is fixed between the crossbeams of the chassis frame; moreover, the bracket is positioned at one ends of the crossbeams of the chassis frame, which are towards an engine head of a fire engine; the upper connecting rod rack is connected with the bracket; the lower connecting rod rack is connected with the bracket; one side of the shoveling plate seat is connected with the upper connecting rod rack; moreover, the shoveling plate seat is also connected with the lower connecting rod rack, a first inclined plane and a second inclined plane are formed at the other side of the shoveling plate seat, and the first inclined plane and the second inclined plane form a reversed V shape with each other; the main shoveling plate is fixed with the first inclined plane and the second inclined plane, and a side shoveling plate is respectively connected in the height directions of both sides of the main shoveling plate; the acting cylinders are hinged on the bracket; and moreover, the columns of the acting cylinders are connected with the shoveling plate seat. During block removal, the road block removal device of the fire engine is very beneficial to expelling blocks towards both sides, and the resistance can be decreased; moreover, the efficiency of block removal is enhanced, and the vehicular power consumption is saved; the road block removal device of the fire engine can adapt to the effect of flexibility at a working state and a non-working state; and the road block removal device of the fire engine has a simple structure and is beneficial to manufacture, installation and maintenance.

Description

technical field [0001] The invention belongs to the technical field of special vehicles, and in particular relates to a road obstacle removal device for a fire truck. Background technique [0002] Obstacles inevitably exist on the roads where the public security fire department dispatches the police for emergency rescue and disaster relief. Limited to the example of obstacle removal, it will affect the traffic of vehicles. However, if there is no dedicated vehicle-mounted obstacle removal device, it will undoubtedly seriously delay the obstacle removal time, and manual removal of obstacles is not only inefficient but also labor-intensive. [0003] The technical information of all road obstacle removal devices can be seen in the published Chinese patent documents, typically such as the "road repair vehicle" recommended by the authorized announcement number CN2255388Y. And objectively can make up for the deficiency of CN2039707U (motor vehicle suspension device) and CN208269...

Problems solved by technology

[0002] Obstacles inevitably exist on the roads where the public security fire department dispatches the police for emergency rescue and disaster relief. Limited to the example of obstacle removal, it will affect the traffic of vehicles. However, if there is a lack of dedicated vehicle-mounted obstacle removal device, it will undoubtedly seriously delay the obstacle removal time, and artificial removal of obstacles is not only inefficient but also labor-intensive.

[0003] The technical information of all road obstacle removal devices can be seen in the published Chinese patent documents, typically such as the "road repair vehicle" recommended by the authorized announcement number CN2255388Y. And objectively can make up for the deficiency of CN2039707U (motor vehicle suspension device) and CN2082696U (road wrecker), but still there are following shortcomings: one, because the structure of V-shaped push blade and the coordination of it and wing are unreasonable, thus In the actual process of clearing obstacles, it is not conducive to driving obstacles, especially obstacles such as rubble and snow, from the center to both sides. Therefore, on the one hand, the resistance of clearing obstacles is increased, and on the other hand, the efficiency of clearing obstacles is affected. On the one hand, it leads to an increase in vehicle energy consumption; second, because the wings only act as a connection to the V-shaped push blade, they themselves cannot participate in clearing obstacles well, so the function is single; third, due to the complexity of the overall structure, for example, in addition to the first, In addition to the second driving device (both oil cylinders), additional lifting devices and even hooks are required, so both manufacturing and assembly are relatively troublesome, and it is economical and cheap and difficult to maintain
