Abstract
The utility model relates to a transmission mechanism of hydraulic four-column lifters. The upper part of a column is provided with a large cross bearer, and the lower part of the large cross bearer is provided with a large oil cylinder. The end part of a piston rod is provided with a draw plate, and a movable pulley is arranged on the draw plate. Two plate type chains are arranged between fixed pulleys and the movable pulley. When the transmission mechanism works, the piston rod is driven by a piston and is pumped into the large oil cylinder, meanwhile, the movable pulley on the draw plate is driven to move to the left, the two plate type chains are respectively pulled by the movable pulley to move to the left, and thus a vehicle platform is lifted. The draw plate is positioned at the middle parts of the two groups of fixed pulleys, so the piston rod moves by one metre, the pulled chains on the upper and the lower parts of the piston rod are one metre, that is to say the chains are pulled by two metres, and thus the lifting height is two times as much as the range ability of the piston rod. The lifting speed is obtained by the flow rate of oil. The utility model has the advantages of simple structure, reasonable design and safe and reliable operation, and the utility model is an ideal transmission mechanism of lifters.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of hydraulic lifting machine drive motor.
Background technology
The transmission device that is used for auto hoist at present all is to drive the elevator form of steel rope or the transmission realization vehicle hoisting of drive motor chain by the motor-driven reductor.But this lifting mechanism is huge, the transmission complexity, and the fault rate height, and dangerous.Therefore this lifting equipment is in operation not really desirable.Also do not use in practice at present with the utility model like products.
Summary of the invention
It is simple that the purpose of this utility model provides a kind of transmission device, and the vehicle hoisting mechanism of safe in operation is to solve the practical problems that prior art exists.
Structure of the present utility model as shown in drawings; One cross bearer is arranged between column, in the cross bearer bottom one large tank is arranged, there is an arm-tie piston rod end of large tank, and two movable pulleys are arranged on the arm-tie.4 fixed pulleys are arranged on the riser of cross bearer end, one wheel flutter is respectively arranged in both sides, mechanism bottom.Between the size fixed pulley and a board-like chain respectively arranged between the big or small movable pulley.Board-like chain lower end is bound up on the lifting platform.The upper end is fixed on the cross bearer.Method of work of the present utility model is: when large tank was worked, piston drove piston rod and is drawn in the large tank, and piston rod drives arm-tie simultaneously, arm-tie drive again big or small movable pulley left direction move.The board-like chain that the size movable pulley spurs respectively again between big or small movable pulley and big or small fixed pulley is twitched left.At this moment, the board-like chain between the big or small movable pulley is blocked by big fixed pulley, and the board-like chain between the big or small fixed pulley is blocked by little fixed pulley.Therefore piston rod spurs chain, and chain spurs the automobile platform again to rising.Reach the lifting purpose.The height of this mechanism lifting is exactly the length that chain is drawn in, and the length that chain is drawn in is two times of piston rod miles of relative movement.Because be positioned at the arm-tie upper and lower one group of fixed pulley is arranged respectively, arm-tie is positioned at the middle part of two groups of fixed pulleys.When piston rod moved, chain was drawn in.Piston rod moves one meter, and the chain that is drawn in also respectively is one meter in the piston rod upper and lower, so piston rod moves one meter, chain is elongated two meters.Just the automobile platform is by two meters of liftings.The lifting speed of this mechanism then decides by the flow velocity of regulating hydraulic oil.The utility model is simple in structure, and is reasonable in design.It is safe and reliable to operate, and operates steadily.It is a kind of desirable lifting machine transmission device.
