Abstract
The utility model discloses a cab capable of ascending and descending. The cab comprises a cab and a support frame, wherein the cab is provided with a base, the support frame is fixedly arranged on a vehicle body, a connecting rod, a support rod and an oil cylinder are sequentially arranged on the support frame from top to bottom, the connecting rod is movably connected with the support frame, the tail end of the connecting rod is movably connected with the lower part of the back side of the cab through a pin shaft, the support rod and the tail end of the oil cylinder are movably connected with the base of the cab through a pin shaft, and the oil cylinder is respectively connected with an operation handle and a hydraulic oil pump through a maintaining valve and a reversing valve. The cab capable of ascending and descending has the advantages that the cab can be controlled to realize ascending and descending through the operation handle, the problem of view sight limitation of drivers can be solved, and other unnecessary troubles cannot be caused. The technical problems that the height of the cab of the engineering machinery in the prior art cannot be regulated, the work view sight is influenced, and the operation is inconvenient are solved.
Description
technical fieldthe utility model belongs to engineering machinery driving cabin technical field, relates to the operator's compartment that the lifting of a kind of energy and lifting can be controlled, and is 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 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 there being the region of limitation in height.
summary of the inventionthe purpose of this utility model is to solve prior art engineering machinery driving cabin to have the highly non-adjustable work visual field and the unhandy technical matters of affecting, and provides a kind of liftable operator's compartment, the deficiency existing to overcome prior art.
A kind of liftable operator's compartment of the utility model, it comprises with the operator's compartment of base and is fixedly mounted on the support on car body, on described support, be provided with successively from top to bottom connecting rod, pole and the oil cylinder being flexibly connected with it, the end of described connecting rod is flexibly connected by bearing pin with the rear side lower part of operator's compartment, and the end of described pole and oil cylinder is flexibly connected with operator's compartment base by bearing pin; 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 utility model can be controlled 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 prior art engineering machinery driving cabin and had the highly non-adjustable work visual field and the unhandy technical matters of affecting.
accompanying drawing explanationfig. 1 is the utility model structural representation;
Fig. 2 is the utility model bar handle pilot oil cylinder working principle schematic.
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 utility model with the operator's compartment 6 of base 4 and is fixedly mounted on the support 1 on car body, on described support 1, be provided with successively from top to bottom the connecting rod 3, pole 2 and the oil cylinder 5 that are flexibly connected with it, the end of described connecting rod 3 is flexibly connected by bearing pin 7 with the rear side lower part of operator's compartment 6, and the end of described pole 2 and oil cylinder 5 is flexibly connected with operator's compartment base 4 by bearing pin; 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 utility model and principle of work:
As shown in Figure 1, the support 1 in the utility model 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, be connected by bearing pin with connecting rod 3.
As shown in Figure 2, in work, when needs raise 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 providing from hydraulic oil pump 10 enters the large chamber of oil cylinder, and cylinder piston rod is stretched out; Because oil cylinder 5 extends, drive pole 2 to rotate up around bearing pin, pole 2 ends progressively raise; The base 4 being connected with pole 2 increases simultaneously, has reached the effect that operator's compartment 6 raises; 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 providing from hydraulic oil pump 10 enters oil cylinder loculus, and cylinder piston rod is regained; Pole 2 is rotated down around bearing pin, and pole end progressively declines; The base 4 being connected with pole 2 declines simultaneously thereupon, has reached the effect that operator's compartment 6 declines.
Claims (2)
