Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated:
Fourth mast post high-altitude operation platform includes a chassis 1, and chassis 1 is the framed structure of a rectangular structure.On chassis 1, be provided with motor 5, Hydraulic Station 6, hydraulic control unit 7, electric apparatus control apparatus 13, walking engine installation 2 and working stand 14.Corner around the chassis is provided with four anti-dumping supporting legs 3 and four screw rod leveling supporting legs 4.Around the chassis, be provided with four groups of telescopic lower masts 11, on every group of telescopic lower mast, be provided with one group of lower mast elevating drive mechanism.On the one joint lower mast of the top of four groups of telescopic lower masts, be provided with a rigid support, on rigid support, be provided with pivoting support 10, workplatform 9 is installed on the pivoting support 10.The joint number of telescopic lower mast is decided on the design height of high-altitude operation platform, and its quantity can be more than three joints or three save.Telescopic lower mast adopts the section bar of special construction to make, and its cross section is a rectangular configuration, and the both sides of rectangular configuration are respectively arranged with finned guide plate 18 and chute 19.The head of four groups of telescopic lower masts saves lower mast and is fixed on the chassis 1, and other a few joint lower masts are inserted in the adjacent lower mast by finned guide plate 18 and chute 19 respectively, thereby constitutes one group of telescopic lower mast.
The elevating drive mechanism that is arranged in every group of telescopic lower mast is made of hydraulic actuating cylinder 15, pulley 17 and chain or steel rope 16.Hydraulic actuating cylinder 15 is installed in the second joint lower mast, and pulley 17 is installed in the top of lower mast, and the two ends of chain or steel rope 16 are separately fixed at the bottom and the top of the adjacent two joint lower masts of the joint lower mast that the pulley place is installed.The lower mast elevating drive mechanism provides pressure oil by Hydraulic Station 6, and by the hydraulic cylinder synchronous delivery pressure oil of hydraulic control unit 7 in four groups of lower masts, by the cylinder plunger jack-up second joint lower mast, respectively save lower mast by pulley 17, chain or steel rope 16 drivings then and do the synchronization lifting motion, thereby the platform 9 that pushes the work forward is done dipping and heaving.
The pivoting support 10 that is arranged on the rigid support that saves at four groups of telescopic lower mast tops one includes gyration gear ring 20 and planetary wheel 21 two parts.Planetary wheel 21 is installed on the workplatform, and planetary wheel is meshed with transferring power with swiveling gear.The end of planetary gear wheel shaft 22 is provided with device for revolving and driving 23, and device for revolving and driving can be a manually operated, also can be DYN dynamic.By device for revolving and driving, can make workplatform be 360 degree very easily and rotate.
In order further to enlarge the swinging radius of workplatform,, can add an operative minor platform 26 in a side of workplatform 9.The operative minor platform is a rectangular configuration, is inserted into by set guide rail 24 in the channel suspending rail of bottom of workplatform 9.In the channel suspending rail of the bottom of workplatform 9, also be provided with the telescopic control device 25 of auxiliary platform, can realize the fore and aft motion of auxiliary platform very easily by telescopic control device.In addition, around workplatform, also be equipped with guard rail rod 8, to improve its safety performance.
Mode of operation of the present utility model is achieved like this:
When high-altitude operation platform need travel or be mobile, can handle walking engine installation 2 by the travel controls button on steering tiller 14 and the handle, to realize advancing of its complete machine, retreat and turn to.When high-altitude operation platform need hoist or decline or workplatform when resting on a certain height, can be by handling the button on the electric apparatus control apparatus 13, make Hydraulic Station work, produce pressure oil, and pass through hydraulic control unit 7, four groups of cylinder plungers are hoisted synchronously simultaneously to four groups of hydraulic actuating cylinder 15 fuel feeding, promoting the telescopic lower mast of second joint hoists, and by chain or steel rope 16, pulley 17 is with the 3rd, the 4th joint ... lower mast rises simultaneously, thereby promotes platform and load rising.When the motor in the Hydraulic Station quits work, under the effect of the valve of pressure oil in hydraulic control unit, remain in the hydraulic actuating cylinder, thereby can make workplatform remain on the required height of work.Workplatform when work, can be according to its operating range and needs, handle the device for revolving and driving 23 on the workplatform and the retractor device 25 of auxiliary platform, to realize its revolution and to strengthen the purpose of its swinging radius.When workplatform need descend, then can pass through operating hydraulically operated control unit, the pressure oil in the hydraulic actuating cylinder is back in the fuel tank.At this moment, hydraulic actuating cylinder, plunger lower mast, workplatform, load then descend together.What be arranged at that working stand 12 on the chassis then can give operating personal brings great convenience up and down.
