A kind of workbench of the invention can with the mast type car for work high above ground of transverse shifting, its working principle is that:Work as work When making the telescopic arm of Operation Van to a direction full extension, the turntable 7 below telescopic arm drives the cooperation rotation of rotary shaft 811 Bearing 812 is rotated in supporting block 813, and the rotation tabs 816 in rotary shaft 811 is made to go to the direction where telescopic arm, Internal structure is pushed to generate transmission, the spring shock absorption bar 814 inside anti-dumping pedestal 8 passes through to damping hydraulic stem 815 It carries out compression and slows down the vibration generated when carrying out rotation transverse shifting from high-altitude operation vehicle, keep high-altitude operation vehicle gentle Carry out transverse shifting, when the rotation of rotation tabs 816 to direction where telescopic arm, to the convex block pushing block 821 of corresponding direction into Row pushes, and convex block pushing block 821 is made to push transmission curved bar 822, and curved bar runner 823 auxiliary of the transmission curved bar 822 in its lower end is allowed to move It is moved in runner limiting slot 824 under dynamic, to pull interlocking bar 825 that bracket curved bar 826 is allowed to fix consolidating for bracket 827 It is rotated under fixed auxiliary, is pushed for next structure, generated powered and be driven straight-bar 828, make to be driven straight-bar 828 It allows the straight-bar sliding block 829 of its end to be displaced under thrust, to push connecting rod 831, is fixed in auxiliary rod 832 with auxiliary rod It is mobile inside phase under the auxiliary of block 833, it generates thrust and pushes push rod 834, make the push rod sliding block 835 of 834 end of push rod in sliding block Sliding block push top 837 is pushed under the limitation of guide rail 836, the thrust for allowing sliding block push top 837 to against reset spring 838 presses slippery fellow and pushes away Bar 839 allows foxy push rod 839 that guide rail slide block 841 is driven, to movement, effectively to delay thrust under the limitation of limit guide rail 842 Dash carries out stable transmission, so that the abrasion between reducing driving member, prolongs its service life, allows driving member to possess longer The long working time, when guide rail slide block 841 moves down, the head end of coupled slide block connecting rod 843 is moved down, from And its end is allowed also and then to make displacement, push mobile tooth row 844 to be moved, under the movement of mobile tooth row 844, with its phase The lower gear 851 of engagement also and then rotates, and the power steering that turns of lower gear 851 is reached gear by gear drive band 852 853, make gear 853 that transmission tooth row 871 be driven to be displaced, in the case where the displacement of transmission tooth row 871 pushes, the tooth row of end Pushing block 872 againsts to be shunk on the outside of the thrust phase of spring 873, and tooth row pushing block 872 is allowed to be moved, to drive promotion flat Bar 874 and then makes transmission, so that the flat bar movable block 875 of end is moved down drive transmission slide bar 876 and presses slide bar firm banking 877, make slide bar firm banking 877 that anti-tilt support block 878 be driven to be declined, cooperates 879 pairs of branch of support non slip surface of lower surface Support face is propped up, and generates one positioned at the fulcrum for stressing direction for high-altitude operation vehicle, high-altitude operation vehicle is slightly propped up, height is made The center of gravity of idle job vehicle offset passes through gravity suffered by high-altitude operation vehicle reasonable from stable center is newly returned to Weight is dispersed to supporting surface and provides the working environment of a safety and stability for staff by position of centre of gravity.
The present invention is combined with each other by above-mentioned component, and a kind of workbench of the present invention can be high with the column type of transverse shifting Idle job vehicle slightly props up high-altitude operation vehicle in flexible corresponding direction by the anti-tilt support block of starting telescopic arm direction of extension, A fulcrum is provided for the center of gravity of offset, center of gravity is made to be back to stable center under the support of fulcrum, allows high-altitude operation vehicle Weight can be dispersed to supporting surface by reasonable position of centre of gravity by suffered gravity, to reduce overturning danger, for the people that works Member provide a safety and stability working environment, with this come solve a kind of workbench of the prior art can be with the mast of transverse shifting Pillar high-altitude operation vehicle, when the arms of high-altitude operation vehicle is stretched to some direct limit, due to the people on job platform With the weight of telescopic arm, the center of gravity of high-altitude operation vehicle is made to generate offset under the effect of external force, it is mobile from stable center The direction stretched to telescopic arm, makes the support of high-altitude operation vehicle lose balance, causes high-altitude operation vehicle easily to telescopic arm Direction of extension inclination, the dangerous problem overturned.
Specific embodiment described herein is only to give an example to the present invention.The technical field of the invention Technical staff can make various modifications or additions to the described embodiments or be substituted in a similar manner, but Without departing from of the invention or beyond the scope of the appended claims.
