Abstract
The invention relates to a fire truck cab turning system. The system consists of a single-oil port hydraulic cylinder, an electric gear pump, an operation handle, an auxiliary support rod and an oil pipe, and is characterized in that: the upper end of the hydraulic cylinder is connected with the cab through a bracket, and the lower end is connected with a frame through a bracket; the electric gear pump is connected with the frame through a bracket; and one end of the support rod is connected with a corresponding bracket on the frame through a hinge pin, and the other end is clamped by a spring clip. The fire truck cab turning system is suitable for turning the cab with relatively large mass, is safer to use and more convenient to operate, and can satisfy the vehicle development and application in the present and future.
Description
Technical field
The present invention relates to a kind of fire extinguishing tanker cab tilting system, belong to driver's cab turnover design-calculated technical field.
Background technology
At present, common operator's compartment double-cylinder hydraulic overturn system adopts the version of the double insurance hydraulic overturn cylinder of a side band ratchet mostly on the market, adopts hydraulic hand-pump to guarantee required system pressure during upset; Rely on thread drawing mechanism to realize that operator's compartment falls after rise; The characteristics of this mechanism are safety mechanism's more complicated, and the manual pump capacity is little, and it is relatively poor that operator's compartment is fallen after rise mode control; Backguy long-term use sensitivity meeting variation, operation is effort relatively; Being not suitable for the bigger operator's compartment of weight ratio uses.
Summary of the invention
The object of the present invention is to provide a kind of fire extinguishing tanker cab tilting system; Adopt novel high-capacity electric hydaulic gear type pump and large scale double hydraulic cylinder to realize driver's cab turnover; Operator's compartment rises and falls after rise and controls by independent electromagnetic valve, and has independent supplemental support mechanism to realize position limitation protection; The operator's compartment operating needs that suitable weight ratio is bigger, use safer, handle more convenient.
Technical scheme of the present invention is achieved in that the fire extinguishing tanker cab tilting system, is made up of single hydraulic fluid port hydraulic actuating cylinder, electric gear wheel pump, bar handle, auxiliary support bar, oil pipe; It is characterized in that: the hydraulic actuating cylinder upper end is connected with operator's compartment through support, and the lower end connects to ground through support; The electric gear wheel pump connects to ground through support; Strut bar one end is connected with respective holder on the vehicle frame through bearing pin, and the other end then passes through spring clip and tightens.
Good effect of the present invention is to be fit to the bigger driver's cab turnover of quality use, uses safer, manipulation is more convenient; Can satisfy present stage and vehicle development use later on.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is hydraulic actuating cylinder of the present invention and supporting bar structure scheme drawing.
Fig. 3 is electric gear wheel pump of the present invention and operating handle structural representation.
Specific embodiments
Below in conjunction with accompanying drawing the present invention is done further description: the fire extinguishing tanker cab tilting system, form by single hydraulic fluid port hydraulic actuating cylinder 1, electric gear wheel pump 7, bar handle 9, auxiliary support bar 11, oil pipe 6; It is characterized in that: hydraulic actuating cylinder 1 upper end is connected with operator's compartment 4 through support 2, and the lower end is connected with vehicle frame 5 through support 3; Electric gear wheel pump 7 is connected with vehicle frame 5 through support 3; Strut bar 11 1 ends are connected with respective holder 10 on the vehicle frame 5 through bearing pin 13, and the other end then passes through spring clip 12 and tightens.
Shown in Fig. 1-3, press following process work:
1. driver's cab turnover hydraulic actuating cylinder 1 is single hydraulic fluid port hydraulic actuating cylinder, and fluid gets into hydraulic actuating cylinder through this mouthful when the upset operator's compartment; When falling operator's compartment after rise, air self-hydraulic cylinder upper end gets in the cylinder, and under the operator's compartment action of gravity, fluid flows out from this hydraulic fluid port, gets back in the electric hydaulic gear type pump 7 simultaneously.
2. electric hydaulic gear type pump 7 capacity are bigger, and inside can store 3 liters of hydraulic oil.This pump is to adopt first at present at home, and the bigger operator's compartment of especially suitable weight uses, and can guarantee driver's cab turnover and fall after rise steadily, and assurance upset and falling time all were controlled within 40 seconds, operated light laborsaving.Two electromagnetic valves are arranged above the lifting pump, control the upset of operator's compartment respectively and fall operation after rise, can guarantee operator's compartment crawl at any time in upset and falling process, safety is good.
3. lift operation is accomplished by operating handle 9, installs on the handle and rises and two action buttons that descend, and controls driver's cab turnover and falling respectively.Simultaneously, this action button can be used as driver's tool and uses, when needs upset operator's compartment, it is taken out from the tool box, with the connection jaws on top connection jaws and the electric gear wheel pump to after connecting, the operator's compartment that just can overturn, anti-theft is good, and is safe and reliable.
4. strut bar mechanism is made up of several parts such as strut bar fixed support 10, strut bar 11, strut bar locating clip riveted joint support 12, bearing pins 13.After the operator's compartment tilted forward forwards end position to, strut bar 11 tilted forward are gone to blocking position, when hydraulic actuating cylinder 1 normal operation; Strut bar 11 is inoperative; In case hydraulic actuating cylinder 1 lost efficacy, when operator's compartment fell after rise backward, strut bar 11 just played the effect of supporting operator's compartment; Can prevent that contingency from taking place, safe and reliable.
