Abstract
The utility model relates to a main telescopic jib having an eccentric structure for a water tower fire truck, which comprises an eccentric turntable support, an eccentric main telescopic jib, a truck-mounted fire pump, a central water outlet pipeline, a jib telescopic fire water pipeline and an electric remote control fire water monitor, wherein the central water outlet pipeline is connected with the truck-mounted fire pump and is fixed in the center of the eccentric turntable support; the eccentric main telescopic jib is arranged parallel to the central water outlet pipeline and is fixed in an eccentric position of the eccentric turntable support; the jib telescopic fire water pipeline is connected with the central water outlet pipeline; the electric remote control fire water monitor is mounted at the front end of the jib telescopic fire water pipeline; and the truck-mounted fire pump is positioned below the central water outlet pipeline. The utility model ensures that the pipeline of a fire water system for a water tower fire truck has no elbows and the linear loss of water pressure is the minimum value, so that the water tower fire truck can perform fire water jet at maximum flow rate and pressure, and main performance parameters of the water tower fire truck can be improved.
Description
Technical field:
The utility model relates to a kind of main telescopic jib structure of fire fighting truck, and especially a kind of main telescopic jib of water tower fire truck eccentric structure belongs to the fire-fighting equipment field.
Background technology:
The main function of water tower fire truck is that the electrical remote control fire water monitor by the jib top ejects the big-flow high-pressure current and carries out the fire-fighting fire extinguishing operation, and flow size and the pressure size of electrical remote control fire water monitor injection water are the topmost performance indications of water tower fire truck.
All water tower fire truck principal arm framves all are positioned at the turntable centre of gyration at present, fire-fighting fire extinguishing water system pipeline arrives the electrical remote control fire water monitor from the outlet pipeline that is positioned at the centre of gyration, at least will be through 90 ° of elbows more than 4, high pressure fire fighting water linear loss is bigger.Pressure as the water outlet of need assurance electrical remote control fire water monitor just must strengthen the pressure of vehicle-mounted fire pump water outlet, as improve the pressure of vehicle-mounted fire pump water outlet, and then the flow of water pump water outlet will reduce in amplitude, influences the fire-fighting fire extinguishing effect.How to guarantee that water tower fire truck goes out high pressure fire fighting water for fire extinguishing stream with maximum stream flow and pressure injection, be the target of the development of water tower fire truck manufacturer and pursuit always.
The utility model content:
At above-mentioned the deficiencies in the prior art, the utility model provides that a kind of hydraulic pressure linear loss is little, the main telescopic jib of water tower fire truck eccentric structure.
For achieving the above object, the technical solution adopted in the utility model is: the main telescopic jib of water tower fire truck eccentric structure comprises eccentric turntable support, eccentric main telescopic jib, vehicle-mounted fire pump, center outlet pipeline, the flexible fire water pipeline of jib and electrical remote control fire water monitor.Center outlet pipeline and vehicle-mounted fire pump are connected and are fixed on the center of eccentric turntable support.Eccentric main telescopic jib and center outlet pipeline be arranged in parallel and are fixed on the eccentric position of eccentric turntable support.The flexible fire water pipeline of jib is connected with the center outlet pipeline.The electrical remote control fire water monitor is installed in the front end of the flexible fire water pipeline of jib.Vehicle-mounted fire pump is positioned at outlet pipeline below, center.
Adopt this structure can guarantee that the fire fighting water system pipeline of water tower fire truck fire extinguishing operation and electrical remote control fire water monitor are positioned at turntable and turn round positive center, there is not elbow from the fire-fighting fire extinguishing water system pipeline of the flexible fire water pipeline of vehicle-mounted fire pump → center outlet pipeline → jib → electrical remote control fire water monitor, hydraulic pressure linear loss minimum, make water tower fire truck carry out fire water with maximum stream flow and pressure and spray, improve the main performance parameter of water tower fire truck.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is fundamental diagram of the present utility model.
The specific embodiment:
As shown in Figure 1, the main telescopic jib of water tower fire truck eccentric structure comprises eccentric turntable support 3, eccentric main telescopic jib 6, vehicle-mounted fire pump 2, center outlet pipeline 4, the flexible fire water pipeline 5 of jib and electrical remote control fire water monitor 7.Center outlet pipeline 4 and vehicle-mounted fire pump 2 are connected and are fixed on the center of eccentric turntable support 3.Eccentric main telescopic jib 6 be arranged in parallel with center outlet pipeline 4 and is fixed on the eccentric position of eccentric turntable support 3.The flexible fire water pipeline 5 of jib is connected with center outlet pipeline 4.Electrical remote control fire water monitor 7 is installed in the front end of the flexible fire water pipeline 5 of jib.Vehicle-mounted fire pump 2 is positioned at center outlet pipeline 4 belows.
As shown in Figure 2: the main telescopic jib 6 of off-centre is fixed on the eccentric position of eccentric turntable support 3, makes the flexible fire water pipeline 5 of delivery port, center outlet pipeline 4, jib of vehicle-mounted fire pump 2, center and eccentric turntable support 3 center-aligned of electrical remote control fire water monitor 7.Fire fighting truck is when carrying out fire-fighting operation, and by vehicle-mounted fire pump 2 effects, approach center outlet pipeline 4, the flexible fire water pipeline 5 of jib are finally ejected by electrical remote control fire water monitor 7 from fire-fighting liquid tank 8 for water, foam.In this process, whole fire-fighting fire extinguishing water system pipeline does not have elbow, reduces the hydraulic pressure linear loss.And then guaranteeing fire fighting truck in the fire-fighting fire extinguishing process, the electrical remote control fire water monitor can carry out fire-fighting fire extinguishing with maximum stream flow and maximum hydraulic pressure, improves the fire fighting truck extinguishing property.
Adopt this structure can guarantee that the fire fighting water system pipeline of water tower fire truck fire extinguishing operation and electrical remote control fire water monitor are positioned at turntable and turn round positive center, during the fire fighting truck operation, provide power by automobile engine, drive hydraulic oil pump output hydraulic oil by gearbox and power takeoff, finish eccentric main telescopic jib by each control element and executive component in the system and launch and gyration.The flexible fire water pipeline of jib is connected with jib and is fixing, and moves with jib.When jib and fire water pipeline attitude close to the vertical shape, carry out the operation of fire-fighting fire extinguishing water spray.Provide power by automobile engine this moment, and drive vehicle-mounted fire pump by power takeoff, under the effect of water pump, fire water is guided to the outlet pipeline of center from fire-fighting liquid tank, the flexible fire water pipeline of water under high pressure approach jib in the outlet pipeline of center arrives the electrical remote control fire water monitor, realizes that finally water cannon can both carry out high efficiency fire water spraying operation in different azimuth.
The utility model adopts brand-new no water pipe elbow fire fighting water system pipeline structure, makes high pressure fire fighting water linear loss reach minimum degree, and then makes water tower fire truck carry out the operation of fire water ejecting extinguishing with maximum stream flow and maximum pressure.
Adopt fire fighting truck water cannon maximum stream flow of the present utility model to improve 15% than corresponding traditional fire fighting truck water cannon maximum stream flow, and maximum discharge pressure has improved about 20%.Thereby the fire-fighting performance indications of water tower fire truck have been improved.
