Background technology
At present, most of heavy truck is the repair for improving parts (such as engine and its cooling system) under driver's cabin
Convenience, driver's cabin is using the form of may be reversed, safety when in order to ensure driver's cab turnover when repairs, driver's cabin
When being turned to maximum position forward, driver's cabin barycenter must ensure that driver's cabin will not be due to self gravitation effect in front of overturning point
It falls after rise, causes the injures and deaths of under-cab maintenance personal, therefore when overturning driver's cabin repairs, must be requested that operator will
Driver's cab turnover can just repair operation to maximum position, and driver's cabin is longer by the time for being turned to maximum position needs, and
Part maintenance activity does not need to spend cab spoiler greatly, as long as there is enough service clearances, but if drives
The maximum position that sailing room cannot overturn repairs, the dangerous of maintenance personal's injury.Existing cab of heavy truck overturning
Limiting device is mechanical system, and the personnel that need repairing manually lock limiting device, inconvenient to use, in addition by limiting device
When locked, operating personnel are located at cab bottom, and there are security risks.
Utility model content
The purpose of this utility model is to provide a kind of cab of heavy truck overturning automatic limit device, can realize driving
When room barycenter is after overturning point, the automatic spacing of any position.
The technical solution of the utility model is：A kind of cab of heavy truck overturns automatic limit device, it is characterised in that：
Mainly it is made of fixed link 1, mobile bar 2, lockable mechanism 3；One end of fixed link 1 is hinged on vehicle frame 5, fixed link 1 it is another
End cap is hinged in the outside of mobile bar 2, the outer end of mobile bar 2 on cab bottom longeron 6, and mobile bar 2 can be along fixation
It is slided up and down inside bar 1；Lockable mechanism 3 is arranged in fixed link 1, is matched with the limiting circular hole in mobile bar.
Advantageous effect：The utility model can realize the automatic spacing of cab of heavy truck overturning, realize driver's cabin
The limit function of low-angle overturning, ensure that the safety of repair, shortens maintenance time.

Fig. 3 is the fundamental diagram of the utility model.
Specific embodiment
To make the purpose of this utility model, content and advantage clearer, with reference to embodiment, to the utility model
Specific embodiment is described in further detail.
As shown in Figure 1, the utility model provides a kind of cab of heavy truck overturning automatic limit device, mainly by fixing
Bar 1, mobile bar 2, lockable mechanism 3 form；One end of fixed link 1 is hinged on vehicle frame 5, and the other end of fixed link 1 is sleeved on movement
The outside of bar 2, the outer end of mobile bar 2 are hinged on cab bottom longeron 6, and mobile bar 2 is along can be upper and lower inside fixed link 1
It slides；
Lockable mechanism 3 is mainly made of latch hook 31, return spring 32, hydraulic cylinder 33, and latch hook 31 is L-type, and bottom end is hinged
In fixed link 1,31 top of latch hook is pressed in the limiting circular hole of mobile bar 2；32 one end of return spring is fixed on fixed link 1
On, the other end is fixed on latch hook 31, and the returning place force of return spring 32 ensures that 31 top of latch hook is pressed on the limiting circle of mobile bar 2
In hole；33 one end of hydraulic cylinder is fixed in fixed link 1, and 33 other end of hydraulic cylinder contacts with latch hook 31, and hydraulic cylinder 33 can
Latch hook 31 is open-top, 31 top of latch hook is made to be detached with the limiting circular hole of mobile bar 2.Mobile bar is equipped with multiple limiting circular holes.
Hydraulic cylinder 33 controls it flexible by driver's cab turnover hydraulic control system, hydraulic principle as shown in Fig. 2, its
Middle driver's cab turnover hydraulic control system 4 is the original device of heavy truck, plays pump 42, reversal valve 43, oil cylinder by oil cylinder 41, hand and lifts
Rise oil inlet pipe 44, oil cylinder falls oil inlet pipe 45 after rise, driver's cabin load lifting cylinder 46 forms；The control oil pipe of hydraulic cylinder 33 is connected to oil cylinder and returns
It drops on oil pipe 45, i.e., when only driver's cabin is fallen after rise, the hydraulic cylinder of hydraulic cylinder 33 can just extend, and jack up latch hook 31, make latch hook 31
Top is detached with the limiting circular hole of mobile bar 2.
When driver's cabin lifts, the driver's cab turnover limiting device course of work is as follows：
Reversal valve 43 is rotated into lift location, makes pump 42 by starting, driver's cabin load lifting cylinder 46 lifts driver's cabin.
Mobile bar 2 is pulled out from fixed link 1, and latch hook 31 is pressed under the active force of return spring 32 in mobile bar 2.
When driver's cabin give rise to a certain position it is motionless when, latch hook 31 is pressed on mobile bar under the active force of return spring 32
In 2 circular hole so that mobile bar 2 cannot glide along fixed link 1, play position-limiting action.
When driver's cabin is fallen after rise, the driver's cab turnover limiting device course of work is as follows：
Reversal valve 43 is rotated to and falls position after rise, makes pump 42 by starting, driver's cabin load lifting cylinder 46 retracts driver's cabin.
Oil cylinder falls the hydraulic cylinder 33 of the oil pressure effect on oil inlet pipe 45 after rise, and the hydraulic cylinder elongation of hydraulic cylinder 33 jacks up latch hook
31,31 top of latch hook is made to be detached with the circular hole of mobile bar 2, mobile bar 2 can along 1 slide downward of fixed link (as shown in Figure 3),
Ensure freely falling after rise for driver's cabin.
When driver's cabin, which falls back to a certain position, limits static in advance, reversal valve 43 is rotated into lift location, hydraulic cylinder 33
Hydraulic oil along oil cylinder fall after rise oil inlet pipe 45 flow back to oil cylinder 41, hydraulic cylinder 33 is retracted, and latch hook 31 is in the effect of return spring 32
It is pressed in the circular hole of mobile bar 2 again under power so that mobile bar 2 cannot glide along fixed link 1, play position-limiting action.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, under the premise of the utility model technical principle is not departed from, several improvement and deformation can also be made, these change
The scope of protection of the utility model is also should be regarded as into deformation.
