Description
Technical field:
The utility model relates to a kind of boom type high-altitude operation platform that has Hydraulic Equilibrium Mechanism.
Background technology:
High-altitude operation platform when work must the maintenance level, steadily, safety, the more leveling mode used on telescopic and hybrid combination aerial platform at present has electric liquid leveling and hydrostatic leveling, electricity liquid levelling gear is subjected to the influence of electronic product sensitivity, more or less rock and hysteresis phenomenon, bring unsafe sensation to operating personal, and electrohydraulic servo device costs an arm and a leg, and manufacturing cost is risen significantly.
Existing hydrostatic levelling gear is to be composed in series closed loop system by two identical leveling cylinders of scantling of structure at present, not influenced by external system, simple in structure, cost is low, and the dipping and heaving of job platform and leveling are carried out synchronously, its leveling process is continuous, steadily, the leveling performance is good, the control accuracy height, dynamically corresponding fast, practical reliable.But blemish in an otherwise perfect thing is that the two oil cylinder claimed structure sizes of levelling gear are identical, exists limitation on the total system structural arrangement.
Summary of the invention:
The purpose of this utility model provides a kind of high-altitude operation platform leveling equipment, and it adopts safe and reliable hydrostatic efficiently levelling gear, satisfies the steady and continuity of high-altitude operation platform leveling.
Technical scheme: the high-altitude operation platform leveling equipment, principal arm and supporting base are hinged by the bearing pin III, and an end of actuating cylinder is connected with supporting base by the bearing pin II, and the other end of actuating cylinder is hinged by bearing pin I and principal arm; Principal arm amplitude oil cylinder and principal arm and supporting base are hinged by bearing pin XII and bearing pin X III respectively; Upper arm amplitude oil cylinder and principal arm and boxed rod are hinged by bearing pin VIII and bearing pin IX respectively; It is hinged by the bearing pin X to carry out oil cylinder cylinder head and upper junction plate, and piston rod head and the lower connecting plate of carrying out oil cylinder are hinged by the bearing pin XI; Boxed rod and lower link are isometric, and boxed rod and lower link pass through bearing pin IV, bearing pin V and bearing pin VI, the hinged formation parallelogram sturcutre of bearing pin VII with principal arm and upper junction plate respectively; Under win in succession and be connected with platform, it is hinged by bearing pin VI and lower link to win in succession down; Actuating cylinder links to each other by hydraulic oil pipe with the rod chamber of carrying out oil cylinder, and actuating cylinder also links to each other by hydraulic oil pipe with the rodless cavity of carrying out oil cylinder.
The beneficial effects of the utility model, the high-altitude operation platform leveling equipment, it all has greatly improved than leveling system in the past at total system structure and secure context, it is identical to make excessive demands two oil cylinder performances and parameter, but adopt two cylinder rod chamber volume ratios and rodless cavity volume ratio is that definite value can realize job platform steadily constantly, has overcome the limitation that system architecture is arranged.
Description of drawings:
Fig. 1: be structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, the high-altitude operation platform leveling equipment, principal arm 8 is hinged by bearing pin III 7 with supporting base 3, and an end of actuating cylinder 5 is connected with supporting base 3 by bearing pin II 4, and the other end of actuating cylinder 5 is hinged by bearing pin I 6 and principal arm 8; Principal arm amplitude oil cylinder 1 is hinged by bearing pin XII 24 and bearing pin X III 2 respectively with principal arm 8 and supporting base 3; Upper arm amplitude oil cylinder 10 is hinged by bearing pin VIII 9 and bearing pin IX 23 respectively with principal arm 8 and boxed rod 13; Boxed rod 13 and lower link 22 are isometric, and execution oil cylinder 15 cylinder head and upper junction plate 21 are hinged by bearing pin X 14, and piston rod head and the lower connecting plate 18 of carrying out oil cylinder 15 are hinged by bearing pin XI 19; Boxed rod 13 and lower link 22 pass through bearing pin IV 12, bearing pin V 11 and bearing pin VI 20, bearing pin VII 16 hinged formation parallelogram sturcutres with principal arm 8 and upper junction plate 21 respectively; Under win in succession and 18 be connected with platform 17, it is 18 hinged by bearing pin VI 20 and lower link 22 to win in succession down; Actuating cylinder 5 links to each other by hydraulic oil pipe with the rod chamber of carrying out oil cylinder 15, and actuating cylinder 5 also links to each other by hydraulic oil pipe with the rodless cavity of carrying out oil cylinder 15, constitutes closed loop system, is not subjected to the influence of external system; Carry out on the oil cylinder 15 bidirectional balanced valve is installed, can guarantee to make oil cylinder still have certain back pressure owing to certain accidental cause causes hydraulic oil pipe to break at work, workplatform can not turn over suddenly.This closed loop system is equipped with manual recharging oil device, reveals the leveling performance that influences workplatform to prevent to seal with the joint.
The utility model principle of work is as follows:
Principal arm amplitude oil cylinder telescopic drive principal arm hoists or descending motion.When rising, principal arm drives the piston rod retraction Δ l of actuating cylinder
1, ∠ ACB dwindles Δ θ 1, because actuating cylinder and execution oil cylinder are formed C/LOOP, so the fluid of actuating cylinder rodless cavity enters in the rodless cavity of carrying out oil cylinder, carries out the oil cylinder piston bar and stretches out Δ l in proportion
2, ∠ KFL increases Δ θ 1, and platform remains unchanged to the angle of horizontal surface; When the parallelogram sturcutre that upper arm amplitude oil cylinder driving boxed rod and lower link are formed carries out dipping and heaving,, constant all the time with respect to the flat-bed angle at total travel keeping parallelism state.The angle of workplatform and horizontal surface also remains unchanged.Based on same principle, the parallelogram sturcutre that principal arm and boxed rod and lower link are formed is when composite move, and workplatform and horizontal plane angle remain unchanged, and workplatform is level all the time.
