Abstract
The utility model provides a novel hydraulic drive leveling device of an aerial work platform. The novel hydraulic drive leveling device of the aerial work platform comprises an auxiliary jib body, a swinging rack, a leveling hydrocylinder, the aerial work platform, a hydraulic lock and three-position four-way directional control valves. The novel hydraulic drive leveling device of the aerial work platform is characterized in that the aerial work platform is hinged with the swinging rack, the swinging rack is hinged with the auxiliary jib body, the leveling hydrocylinder is hinged with the swinging rack and the auxiliary jib body, and the auxiliary jib body is hinged with a main jib lifting eye through a front hinge point. The novel hydraulic drive leveling device of the aerial work platform has the advantages that the aerial work platform can be leveled as rise and fall of a crane jib synchronously, and therefore the bottom of the aerial work platform is always parallel to the ground. The fact that a support on a working platform is not separated from the aerial work platform is guaranteed, leveling accuracy is high, oscillating quantity of the working platform is little, and the novel hydraulic drive leveling device of the aerial work platform is simple and convenient to operate.
Description
Technical field
The utility model relates to a kind of car hosit and installs high-altitude operation platform additional, particularly a kind of hydraulic-driven leveling equipment of novel high-altitude operation platform.
Background technology
Along with expanding economy both at home and abroad, engineering construction project is more and more, and the frequency of utilization of car hosit, aerial platform is also more and more.Folding-jib aerial platform on the existing market, accurately putting in place of its high-altitude operation platform is slower, and squareness is difficult for adjusting, and delivery head and radius of action also have limitation; Also have a mechanical type manual bolt-type high-altitude operation platform leveling equipment, big, the leveling precision of workplatform oscillating quantity can't guarantee during its aloft work, and bolt-type machinery leveling operation easier is big.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the above-mentioned technology, and a kind of hydraulic-driven leveling equipment of novel high-altitude operation platform is provided.Have easy to operately, can realize the leveling of workplatform hydraulic-driven, and leveling precision height, be installed in and have the characteristics that remain balance with rising and falling of crane arm on the car hosit.
The purpose of this utility model is achieved in that and comprises auxiliary body, swing span, leveling hydraulic ram, high-altitude operation platform, hydraulic lock, three position four-way directional control valve.It is characterized in that high-altitude operation platform and swing span are hinged, swing span and auxiliary body are hinged, and the leveling hydraulic ram is hinged with swing span and auxiliary body respectively, and the auxiliary body is hinged by preceding hinge and principal arm hanger.Car hosit is when realizing the aloft work operating mode, at first change by the flexible arm body angle that realizes of principal arm amplitude oil cylinder, pull auxiliary angle pull bar then and make the three-position four-way valve commutation, under the effect of leveling hydraulic ram, make high-altitude operation platform realize corresponding angle, guarantee high-altitude operation platform all the time with ground level, can finish corresponding operation.Install bidirectional hydraulic lock on the hydraulic actuating cylinder additional, locked hydraulic ram pipeline can prevent that pipe breakage from causing the hydraulic actuating cylinder retraction by actv., and platform inclination has an accident.
The utility model has the advantages that, can make the bottom surface of high-altitude operation platform parallel to the ground all the time with the synchronous leveling high-altitude operation platform of rising and falling of crane arm.Guarantee that the carrier in the workplatform does not detach high-altitude operation platform, and leveling precision height, the workplatform oscillating quantity is very little, and is easy and simple to handle.
Description of drawings:
Fig. 1 is constructional drawing of the present utility model
Fig. 2 is hydraulic principle constructional drawing of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing to the patent further instruction:
High-altitude operation platform 6 is hinged by bearing pin 5 and swing span 2 upper ends, swing span 2 lower ends are hinged by axle and auxiliary body 1 rear end hinge, leveling hydraulic ram 3 is hinged respectively at auxiliary body 1 and swing span 2, wherein cylinder block and auxiliary body 1 hinge are hinged, the flexible rod end hinge of oil cylinder and swing span 2 are hinged, and auxiliary body 1 front end hinge is hinged by bearing pin and principal arm hanger.Bidirectional hydraulic lock 4 is connected on the cylinder body of hydraulic ram by bolt with leveling hydraulic ram 3.
As shown in Figure 2, lead to from swivel coupling that to tell one road to 3-position 4-way hand change over valve P mouth with T-pipe joint in the high pressure fuel pipe of the valve of getting on the bus be oil inlet, three position four-way directional control valve 7 mouthfuls of A, B are connected with bidirectional hydraulic lock 8 hydraulic fluid ports respectively, increase flow regulating valve at this oil circuit, make the action of high-altitude operation platform more steady, flexible by manual reverse of direction valve regulation leveling hydraulic ram, change-over valve T mouth connects in the working connection oil return.
