Abstract
The utility model discloses a hydraulic high-speed rammer compactor piston rod protection structure. The hydraulic high-speed rammer compactor piston rod protection structure comprises a frame, a hydraulic cylinder and a rammer. A cylinder body end of the hydraulic cylinder is hinged to the top of the frame; a piston rod of the hydraulic cylinder is connected with the rammer through a connecting seat; the connecting seat comprises a connector, a connecting ball, a gland and a bolt; the lower end of the connector is connected with the rammer; the piston rod end of the hydraulic cylinder is connected with the connecting ball; the connecting ball is pressed in a semispherical groove at the upper end of the connector through the gland; the gland and the connector are fixedly connected through the bolt. The hydraulic high-speed rammer compactor piston rod protection structure has the advantages of being capable of effectively avoid the phenomenon that because the lower end of the piston rod of the hydraulic cylinder is connected with the rammer through the connecting seat instead of being directly and fixedly connected with the rammer traditionally and when the rammer drops, the connector can rotate in the connector in any direction, the piston rod is bent and broken caused by lateral force generated from the situation that the rammer does not vertically drop, and obviously prolonging the service life of the hydraulic cylinder, and improving the working efficiently of the hydraulic cylinder.
Description
Technical field
The utility model relates to a kind of piston rod protection structure; a kind of hydraulic High-speed Compactor piston rod protection structure particularly, hydraulic High-speed Compactor are to use the high-efficiency appliance in fields such as senior infrastructure such as speedway, high-speed railway, airport and dykes and dams maintenance, urban facilities construction.
Background technology
Oil cylinder one end of present domestic hydraulic pressure beater is installed on the frame; what the other end was direct and hammer ram is fixed; hammer ram whereabouts out of plumb is easy to cause the stressed bending of oil cylinder piston bar to fracture during work; cause oil cylinder short application life; so the operating efficiency that is difficult to reach best must be protected piston rod, improve its application life to reach.
Summary of the invention
The purpose of this utility model is exactly the weak point in the background technology, and a kind of hydraulic High-speed Compactor piston rod protection structure is provided.
In order to achieve the above object; the utility model adopts following technical scheme: a kind of hydraulic High-speed Compactor piston rod protection structure; comprise frame, oil cylinder, hammer ram; cylinder body end and the frame top of oil cylinder are hinged; the tailpiece of the piston rod of oil cylinder is connected with hammer ram by Connection Block; described Connection Block comprises connector, connects ball, gland and bolt; the connector lower end is connected with hammer ram; the tailpiece of the piston rod of oil cylinder be connected ball and connect; gland will connect in the semi-round ball groove that ball is pressed into connector upper end, and gland and connector are bolted to connection.
For a kind of optimization of the present utility model, connecting ball is the ball shape, and the spheroid upper and lower side is processed with platform respectively, between the upper and lower side platform longitudinally axial line be provided with a through hole, the tailpiece of the piston rod of described oil cylinder is connected with this through hole.
For a kind of optimization of the present utility model, connector upper surface longitudinally axial line is provided with upward opening and is connected second ball groove that ball mates, and gland lower surface longitudinally axial line is provided with under shed and is connected first ball groove that ball cooperates.
The utility model is compared with background technology, traditional oil cylinder piston bar lower end directly is connected with hammer ram by Connection Block the fixedly connected oil cylinder piston bar lower end that changes into hammer ram, hammer ram is when falling, connecting ball can rotate by any direction in connector, the lateral force that can effectively avoid hammer ram whereabouts out of plumb to produce causes the piston rod bending to fracture, but in the application life of significant prolongation oil cylinder, operating efficiency is improved.
