Abstract
The utility model discloses a driving cab capable of being elevated. The driving cab comprises a driving cab assembly, a rear frame and a hydraulic system, wherein an elevating mechanism is arranged between the driving cab assembly and the rear frame; the elevating mechanism which is a quadrilateral mechanism is connected with an electric control liquid device and a power device; the quadrilateral mechanism comprises an upper connecting rod assembly, a lower connecting rod assembly and an oil cylinder; the upper connecting rod assembly is horizontally arranged with one end rigidly connected with the driving cab and the other end articulated with the rear frame; the lower connecting rod assembly is horizontally arranged with one end rigidly connected with the driving cab and the other end articulated with the rear frame; and one end of the oil cylinder is articulated with the upper connecting rod assembly and the other end thereof is articulated with the rear frame. The advantages include: freely elevating and adjusting the driving cab device, improving the safe distance between the driving cab and a plane when a driver connects the plane or conducts pushing operation and achieving the effect that a single person can alone conduct the operation of towing planes to comply with the operation habit of people. Besides, the driving cab also resolves the contradiction between the passing capability of a towing vehicle and operation field of vision.
Description
Technical field
The utility model relates to a kind of operator's compartment, specifically relates to a kind of operator's compartment that can lifting.
Background technology
Existing aircraft towing generally is to adopt two class chassis operator'ies compartment, operator's compartment can not carry out the easy on and off adjustment according to the needs of aircraft, what perhaps have only can do the rise and fall adjustment on the chassis, the amplitude of rise and fall is very little, and can not guarantee safety distance between tractor truck and the aircraft, can not solve tractor truck airport infield ground crossing ability and and the operation visual field between contradiction.There are potential safety hazard in operator's compartment and institute's towing aircraft during towing aircraft.
Summary of the invention
The utility model is at the deficiency of prior art, provide a kind of can lifting simultaneously before and after the operator's compartment of translation.
Below introduce structure of the present utility model in detail, a kind of operator's compartment that can lifting, comprise operator's compartment assembly, back vehicle frame, hydraulic efficiency pressure system, between operator's compartment assembly and the back vehicle frame lifting mechanism is set, be connected with automatically controlled liquid device and engine installation on the lifting mechanism, described lifting mechanism is a quadrangular mechanism; Described quadrangular mechanism comprises boxed rod assembly, lower link assembly and oil cylinder; Described boxed rod assembly is horizontally disposed with and an end and operator's compartment an are rigidly connected end is with afterwards vehicle frame is hinged; Described lower link assembly is horizontally disposed with and an end and operator's compartment an are rigidly connected end is with afterwards vehicle frame is hinged; Described oil cylinder one end and the hinged end of boxed rod assembly are hinged with the back vehicle frame.
Optimally, described hydraulic efficiency pressure system is provided with hydraulic lock.
Optimally, described hydraulic efficiency pressure system is provided with hydraulically balanced valve.
The utility model has the advantages that and can free lifting adjust the operator's compartment device, improved the safety distance of chaufeur operator's compartment and aircraft when connecting aircraft and pushing tow operation, can people's separate operaton when carrying out towing aircraft, be accustomed to the manipulation that meets people.This operator's compartment has also improved the contradiction between the tractor truck crossing ability and the operation visual field.The whole operator's compartment of no bar tractor truck can lifting, and automatically controlled liquid broad application has obtained realization here, has embodied operator's compartment and engine installation, driving device, complete flexible connection of electrical controller, makes above-mentioned lifting control loop become possibility.
Description of drawings
Fig. 1 is that the utility model passes through the scheme drawing after the quadrangular mechanism operator's compartment descends;
Fig. 2 is that the utility model passes through the scheme drawing after the quadrangular mechanism operator's compartment rises.
The specific embodiment
Below in conjunction with Figure of description utility model is done further to disclose.
As depicted in figs. 1 and 2, the utility model is a kind of operator's compartment that can lifting, comprise operator's compartment assembly 1, back vehicle frame 2, hydraulic efficiency pressure system, between operator's compartment assembly 1 and the back vehicle frame 2 lifting mechanism is set, be connected with automatically controlled liquid device and engine installation on the lifting mechanism, described lifting mechanism is a quadrangular mechanism.Quadrangular mechanism comprises boxed rod assembly 3, lower link assembly 4 and oil cylinder 5; Described boxed rod assembly 3 is horizontally disposed with and an end and operator's compartment assembly 1 middle part the are rigidly connected other end is with afterwards vehicle frame 2 is hinged; Described lower link assembly is horizontally disposed with and an end and operator's compartment assembly 1 bottom an are rigidly connected end is with afterwards vehicle frame 2 is hinged; Described oil cylinder 5 one ends and boxed rod assembly 3 hinged ends are hinged with back vehicle frame 2.Described hydraulic efficiency pressure system is provided with hydraulic lock and hydraulically balanced valve.
Propradation: realize that by engine installation, automatically controlled liquid device oil cylinder 5 stretches out, because under the effect of hydraulically balanced valve, effect does not steadily have vibration.Boxed rod assembly 3 is that fulcrum carries out the clickwise rising around itself and back vehicle frame 2 bonded assemblys one end at this moment, boxed rod assembly 3 drives the 1 upwards lifting of operator's compartment assembly simultaneously, lower link assembly 4 is that fulcrum carries out the clickwise rising around itself and back vehicle frame 2 bonded assemblys one end, thereby realize the rising of operator's compartment assembly 1, and can rise to oil cylinder 5 and reach pole location.
Decline state: realize oil cylinder 5 indentations by engine installation, automatically controlled liquid device, because under the effect of hydraulically balanced valve, effect does not steadily have vibration.Boxed rod assembly 3 is that fulcrum carries out left-hand revolution decline around itself and back vehicle frame 2 bonded assemblys one end at this moment, boxed rod assembly 3 drives 1 decline of operator's compartment assembly simultaneously, lower link assembly 4 is that fulcrum carries out left-hand revolution decline around itself and back vehicle frame 2 bonded assemblys one end, thereby realize the decline of operator's compartment assembly 1, and can drop to oil cylinder 5 and be retracted to pole location.
Because operator's compartment can freely be adjusted height when towage, improved the operation visual field.Cab heights can be adjusted into highest position under the non-job status, its various road conditions (such as by scrubbing the pond in the airport) through performance of travelling obviously is better than the tractor truck of other types.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
