Abstract
An overturning cab of a bulldozer belongs to the field of engineering machinery and is characterized in that the overturning and the resetting of the cab can be realized by the stretching of a hydraulic cylinder, a hydraulic oil circuit directly utilizes a steering hydraulic system of the bulldozer, the operation is convenient, the use is safe, the overhauling difficulty of a transmission system of the bulldozer is lowered effectively, and the vibration can be alleviated by the elastic connection between a floor of the cab and a wing plate.
Description
Technical field
Patent of the present invention belongs to engineering machinery field, relates in particular to bulldozer and uses turning driver's cabin.
Background technology
The driver's cabin that present bulldozer is installed all directly is fastenedly connected with bolt and bulldozer wing plate, seat box; When bulldozer transmission quality defects need be repaired; Can only earlier manipulation, circuit be broken off; Driver's cabin, seat, seat box etc. are pulled down and can be carried out, increased the difficulty when the bulldozer transmission is repaired, prolonged equipment repair time.
The patent of invention content
The purpose of patent of the present invention is to overcome above-mentioned deficiency, has designed a kind of bulldozer cab that can overturn, comprises seat, electrical apparatus control system, control system in this driver's cabin, and driver's cabin is installed on the floor and the floor forms an integral body.Floor and wing plate are articulated and connected, through oil cylinder flexible with the floor with driver's cab turnover with reset.
Patent of the present invention adopts following technical scheme for realizing above-mentioned purpose:
Automatically controlled mode is adopted in the manipulation of installing in the said bulldozer upset of the patent of the present invention driver's cabin, and control wire harness and air-conditioning fluorine pipe are installed the position near pin joint from the driver's cabin right side.Driver's cabin is installed on the floor through bolt, and all around through adhesive tape compacting sealing, seat, manipulation etc. are directly installed on the floor in the driver's cabin.The right side, floor is connected with wing plate through articulated manner, between floor and the wing plate oil cylinder is housed, through oil cylinder stretch the realization driver's cabin upset and reset.When driver's cab turnover when requiring the position, through the safe locking device of installing on the right wing plate driver's cabin is locked, cause security incident to prevent the driver's cabin unexpected reset.The driver's cabin back that resets is fixed driver's cabin through the hold down gag on the left wing plate, realizes damping through two rubber bases on the wing plate and the rubber pad between the twisted axis.
Beneficial effect of the present invention: the application party of patent of the present invention the maintenance of bulldozer transmission, avoided unnecessary dismounting, improved the repairing efficient of drive disk assembly; The form of structure that driver's cabin is installed is beneficial to the inner sealing of driver's cabin, can effectively reduce the driving room noise; Adopt the elastic shock attenuation structure, the impact shock in the bulldozer work is effectively isolated, improved driver's working environment.
Description of drawings
Fig. 1 is the sketch map behind the upset driver's cab turnover;
Fig. 2 is the upset driver's cabin securing sketch map that resets;
Fig. 3 is a upset driver's cabin hydraulic schematic diagram;
The specific embodiment
Be described in detail in conjunction with the content of accompanying drawing the present technique scheme.
As shown in Figure 1, the described upset driver's cabin of patent of the present invention includes driver's cabin 1, safe locking device 2, wing plate 3, hoist cylinder 4, floor 5, cushion socket 6, hold down gag 7 compositions.This bulldozer that relates to the driver's cabin that overturns adopts automatically controlled mode, comprises seat, control frame, air-conditioning, instrument etc. in the driver's cabin.Driver's cabin 1 is installed on the floor 5 through bolt, seals through the weather strip compacting between driver's cabin and the floor.Seat that driver's cabin is inner and manipulation etc. are directly installed on the floor.The floor is hinged on the wing plate 3 of the right through two rotating shafts, and the floor another side is installed on the wing plate of the left side through two cushion sockets 6, compresses through hold down gag 7, and vibrations cause the driver's cabin swing when avoiding bulldozer work.Hold down gag can freely rotate, and realizes compressing through spring.Floor bottoms is equipped with telescopic oil cylinder 4, realizes the upset of driver's cabin and resets through the control oil cylinder is flexible.Between cardan axle on the floor and the floor Rubber shock-absorbing pad is housed.This driver's cabin can be realized 55 ° of upsets through above structure.
Be illustrated in figure 2 as the driver's cabin securing sketch map that resets, driver's cabin realizes that through the rubber pad in cushion socket, the jointed shaft elasticity is connected with the bulldozer wing plate, through hold down gag driver's cabin is fixed on the wing plate, prevents that driver's cabin is unexpected to overturn.
Be illustrated in figure 3 as upset driver's cabin hydraulic schematic diagram, this system is made up of oil pump, control valve, fuel tank, telescopic oil cylinder.Oil pump is directly used the bulldozer steering pump, and the output pressure of steering pump is guided on the control valve.Control valve is manual three-position four-way valve, through handle control valve is pulled position, a left side during upset, and oil cylinder stretches out driver's cabin and realizes upset; After driver's cab turnover puts in place, control valve is pulled meta, the oil cylinder position locking; Driver's cabin resetted when control valve was pulled right position.The hydraulic oil of this system is directly got back to the bulldozer rear axle box.
The above only is the preferred embodiment of patent of the present invention, is not the structure of patent of the present invention is done any pro forma restriction.Every technical spirit according to patent of the present invention is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of patent of the present invention.
Claims (3)
1. bulldozer upset driver's cabin, it is characterized in that: on one side cab floor is hinged on the wing plate, another side is fixed on the wing plate through hold down gag, hold down gag is unclamped the back realize the upset of bulldozer and reset through oil cylinder is flexible.
2. bulldozer upset driver's cabin according to claim 1, it is characterized in that: telescopic oil cylinder used oil straightening connects from the bulldozer steering pump draws, and hydraulic oil is directly got back to the bulldozer rear axle box.
3. cab floor is connected with wing plate elasticity through rubber pad, realizes damping.
