Abstract
The invention discloses a liftable cab which comprises a cab body with a base and a bracket fixedly arranged on a vehicle body, wherein the bracket is sequentially provided with a connecting bar, a supporting bar and an oil cylinder from top to bottom, the connecting bar, the supporting bar and the oil cylinder are movably connected with the bracket, the tail end of the connecting bar is movably connected with the lower part of the rear side of the cab body through a pin shaft, and the tail ends of the supporting bar and the oil cylinder are movably connected with the base of the cab body through pin shafts; the oil cylinder is respectively connected with a control handle and a hydraulic oil pump through a holding valve and a reversing valve. According to the liftable cab disclosed by the invention, the cab can be controlled by the control handle to ascend and descend, not only is the problem that the view field of a driver is limited solved, but also no other unnecessary trouble is brought. The technical problems that the working view field is affected and the operation is inconvenience as the height of a cab of engineering machinery in the prior art is not adjustable are solved.
Description
technical fieldthe invention belongs to the engineering machinery driving cabin technical field, relate to the operator's compartment that the lifting of a kind of energy and lifting can be controlled, be specifically related to a kind of liftable operator's compartment.
background technologywhen port and pier or freight station utilize various construction machinery and equipment handling goods, because the height in freight container or compartment is higher, chaufeur does not often observe situation in case, at this moment needs a commander to assist operation, has not only affected efficiency but also has increased greatly the work risk.In order to address the above problem, some construction machinery and equipments increase its operator's compartment, although increased the field range of chaufeur,, because the height of operator's compartment increases, when transportation or walking, be difficult to smoothly by the zone of limitation in height is arranged.
summary of the inventionthe objective of the invention is to solve the prior art engineering machinery driving cabin and have the highly non-adjustable work visual field and the unhandy technical matters of affecting, provide a kind of liftable operator's compartment, the deficiency existed to overcome prior art.
A kind of liftable operator's compartment of the present invention, it comprises with the operator's compartment of base and is fixedly mounted on the support on car body, be provided with successively from top to bottom connecting rod, pole and oil cylinder with its flexible connection on described support, the rear side lower part of the end of described connecting rod and operator's compartment is flexibly connected by bearing pin, and the end of described pole and oil cylinder is flexibly connected by bearing pin and operator's compartment base; Described oil cylinder is connected with hydraulic oil pump with bar handle respectively by hold-off valve, change-over valve.
Described connecting rod and pole be arranged in parallel.
The present invention can control rising and the reduction of operator's compartment by bar handle, not only solved the limited problem of driver's seat, does not bring again other unnecessary troubles.Solve the prior art engineering machinery driving cabin and had the highly non-adjustable work visual field and the unhandy technical matters of affecting.
the accompanying drawing explanationfig. 1 is structural representation of the present invention;
Fig. 2 is bar handle pilot oil cylinder working principle schematic of the present invention.
In figure 1, support 2, pole 3, connecting rod 4, base 5, oil cylinder 6, operator's compartment 7, bearing pin 8, bar handle 9, change-over valve 10, hydraulic oil pump 11, hold-off valve
The specific embodiment is according to Fig. 1 and Fig. 2, it comprises the present invention with the operator's compartment 6 of base 4 and is fixedly mounted on the support 1 on car body, be provided with successively from top to bottom connecting rod 3, pole 2 and oil cylinder 5 with its flexible connection on described support 1, the rear side lower part of the end of described connecting rod 3 and operator's compartment 6 is flexibly connected by bearing pin 7, and the end of described pole 2 and oil cylinder 5 is flexibly connected by bearing pin and operator's compartment base 4; Described oil cylinder 5 is connected with hydraulic oil pump 10 with bar handle 8 respectively by hold-off valve 11, change-over valve 9; Described connecting rod 3 and pole 2 be arranged in parallel.
assembling of the present invention and principle of work:
As shown in Figure 1, the support 1 in the present invention is arranged on the car body or workplatform of construction machinery and equipment, it all the time with car body or workplatform in relative static state; Operator's compartment 6 is fixed on base 4 and is connected as a single entity with it; Between base 4 and support 1, by pole 2, with connecting rod 3, by bearing pin, be connected.
As shown in Figure 2, in work, when needs rising operator's compartment 6, rearward pull bar handle 8, change-over valve 9 is opened to the right hold-off valve 11 simultaneously and is opened, and the hydraulic oil provided from hydraulic oil pump 10 enters the large chamber of oil cylinder, and cylinder piston rod is stretched out; Due to oil cylinder 5 elongations, drive pole 2 and rotate up around bearing pin, pole 2 ends progressively raise; The base 4 be connected with pole 2 increases, and has reached the effect that operator's compartment 6 raises simultaneously; In this course, connecting rod 3 all the time with pole 2 keeping parallelisms, due to its existence, make operator's compartment 6 all the time in the state with ground level; .When being elevated to the highest or desired location, make bar handle 8 get back to meta, now hold-off valve 11 lockings, make oil cylinder 5 keep extension elongation constant, the safety while having guaranteed to raise.
During decline, pull forward bar handle 8, change-over valve 9 is opened to the left hold-off valve 11 simultaneously and is opened, and the hydraulic oil provided from hydraulic oil pump 10 enters the oil cylinder loculus, and cylinder piston rod is regained; Pole 2 is rotated down around bearing pin, and the pole end progressively descends; The base 4 be connected with pole 2 descends thereupon, has reached the effect that operator's compartment 6 descends simultaneously.
