Specific embodiment
Fig. 1 is a kind of vertical pillar electrichydraulic control vehicle overall structure figure of the present invention.Including chassis (1A), upright post system
(2A) and workbench (3A), workbench realize raising and lowering function by the lifting of upright post system.
Fig. 2, Fig. 3 are structural schematic diagram and work expanded schematic diagram of the invention respectively.Vertical pillar of the invention is electro-hydraulic
The lifting device of control system combines rotation system by original level-one oil cylinder and chain and is changed to control lifting by three-level oil cylinder,
Mainly there are crossbeam (1), pin shaft (2), oil cylinder trunnion (3), split pin (4), three-level oil cylinder (5), trunnion block (6), first segment column
(7), the second section column (8), third section column (9), Section of four column (10), upper limit position block (11), limit pin shaft (12), upper Buddhist nun
Imperial sliding block (13), lower nylon slide block (14), bolt (15), lower position block (16)；Crossbeam (1) is fixed on the 4th by bolt (15)
It saves on column (10), the top of three-level oil cylinder (5) is connected on crossbeam (1) by pin shaft (2), and split pin (4) is mounted on pin shaft
(2) in the hole on, trunnion block (6) is fixed on first segment by bolt (15) across three-level oil cylinder (5) bottom oil cylinder trunnion (3) and stands
On column (7).When dynamical system is to three-level oil cylinder fuel feeding, three-level oil cylinder (5) pushes Section of four column (10) to move upwards, the
Four section column (10) inner sides are equipped with limit pin shaft (12), and the upper limit position block of third section column (9) is encountered in uphill process
(11) after, Section of four column (10) drives third section column (9) to continue up, and third section column (9) inner side is same
Equipped with limit pin shaft (12), the upper limit position block (11) of the second section column (8), such third section column can be encountered in uphill process
(9) the second section column (8) can be driven to continue toward rising；When decline, under the effect of gravity, the limit on Section of four column (10)
After position pin shaft (12) encounters the lower position block (16) of third section column (9), Section of four column (10) drives third section column (9)
Decline, after the limit pin shaft (12) on third section column (9) encounters the lower position block (16) of the second section column (8), third section is vertical
Column (9) drives the second section column (8) to move downward.Three-level oil cylinder is conducive to simplify the internal junction of level-one oil cylinder and double chain system
Structure reduces the processing of the second section column and third section column, by the chain block and chain, roller system and lube system of original complexity
System all removes, and advantageously ensures that the reliability of system, improves security of system energy.Floor space inside three-level cylinder piston rod
It is identical, can uniformly increase column, make operator's use more steady.
