Embodiment Construction

[0037] The core of the present invention is to provide a telescopic cylinder, which is used to realize the lifting of the tank top fire water cannon of the elevating jet fire truck. Lift the rotating part of the tank top fire water cannon above the top surface of the lifting arm to realize 360-degree omni-directional fire extinguishing; in the driving state, by retracting the piston rod of the telescopic cylinder, the tank top fire water cannon The cannon is lowered below the top surface of the lifting arm frame, so as not to affect the trafficability of the vehicle. The present embodiment will be described in detail below in conjunction with the accompanying drawings.

[0038] figure 1 It is a structural schematic diagram of the telescopic cylinder described in the specific embodiment, figure 2 yes figure 1 The enlarged view of part A shown in, image 3 yes figure 1 Enlarged view of part B shown in . Such as figure 1 , figure 2 and image 3 As shown, the telescopic c...

Abstract

The invention discloses a water tower fire truck and a roof fire water monitor lifting device and a telescoping cylinder thereof. The telescoping cylinder comprises a cylinder body and a piston rod, the cylinder body is provided with an axial through hole, a cavity defined by a inner wall, an outer wall and a bottom wall is arranged at the wall part of the cylinder body, the piston rod is sleeve-shaped, one end of the piston rod is provided with a piston and inserted in the cavity, the other end of the piston extends out of the cavity and is fixedly provided with a flange disc for installing a roof fire water monitor, the piston divides the cavity into a sealed rodless cavity and a sealed rod cavity, and the cylinder body is provided with a first interface and the second interface respectively communicated with the rodless cavity and the rod cavity. The telescoping of the piston rod of the telescoping cylinder provided in the invention does not influence the output of fire extinguishing media; when in use, the telescoping cylinder can lift the roof fire water monitor up to be higher than the top surface of a lifting arm frame to realize 360-dgree omnibearing jet fire extinguishment; and during running, the telescoping cylinder can descend the roof fire water monitor down to be lower than the top surface of the lifting arm frame so as to not influence the trafficability. On the basis of the performances of the telescoping cylinder, the invention also provides a water tower fire truck.

Description

technical field [0001] The invention relates to a height-lifting jet fire truck, in particular to a height-lift jet fire truck and its tank top fire water cannon lifting device and telescopic cylinder. Background technique [0002] With the rapid development of the economy and society, the scale of the city continues to expand, and the number of crowded places, high-rise buildings, public entertainment and other places continues to increase. Therefore, the tasks of fire protection, fire fighting and rescue are becoming increasingly heavy. The configuration form of fire-fighting equipment can no longer meet the current needs of urban fire-fighting. In order to further effectively improve the overall level of firefighting and rescue operations of the fire brigade, more and more fire brigades are equipped with elevating jet fire trucks. [0003] A high-lift jet fire truck generally consists of a special or general-purpose vehicle chassis, a lifting arm, and a fire protection s...
