Description
Technical Field
The utility model relates to a hydraulic ram field specifically is a pedal improvement structure of hydraulic ram.
Background
The pedal of traditional hydraulic ram is as shown in fig. 1, it includes footboard 1, footboard 1 one end is rotated through pivot 2 and is connected in 3 lateral walls of hydraulic ram, footboard 1 below is equipped with the driving plate 4 of liftable, driving plate 4 has one side to stretch into in the hydraulic ram 3 with piston spare rigid coupling, and be connected with spring 6 between driving plate 4 and the hydraulic ram base 5, can make driving plate 4 descend when the pedal is stepped on to the foot, thereby make the piston spare synchronous decline of hydraulic ram 3, footboard 1 when loosening footboard 1, driving plate 4 resets under the effect of spring 6. According to the pedal structure of the hydraulic jack, the pedal 1 is always arranged on the transmission plate 4 and supported by the transmission plate 4, so that the spring 6 is slightly compressed through the transmission plate 4 even if the pedal 1 does not work, and the problem that a small amount of oil liquid still enters the hydraulic jack when the pedal 1 does not work is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a hydraulic ram is pedal to improve structure to solve the problem that prior art hydraulic ram footboard exists.
In order to achieve the above purpose, the utility model discloses the technical scheme who adopts is:
pedal improvement structure of hydraulic ram, including footboard, driving plate, footboard one end is rotated and is connected in the hydraulic ram lateral wall, and the driving plate is located the footboard below, is connected with the spring between driving plate bottom and the hydraulic ram base, and the driving plate has one side to stretch into in the hydraulic ram with piston spare rigid coupling, its characterized in that: the pedal is suspended above the transmission plate through an elastic suspension connecting piece.
The hydraulic jack pedal improves structure, its characterized in that: the hydraulic ram lateral wall fixedly connected with hangs in the roof beam that hangs above the footboard, elasticity hangs in midair the connecting piece including supporting in the supporting baseplate of footboard bottom, and the supporting baseplate is connected with vertical board, hang roof beam slidable mounting has vertical connecting rod, and vertical connecting rod lower extreme passes and hangs roof beam and the vertical board of fixed connection, and vertical connecting rod upper end is located and hangs the roof beam top, and vertical connecting rod upper end is connected with the roof, is connected with the supporting spring of cover outside vertical connecting rod between roof and the hanging roof beam.
The hydraulic jack pedal improves structure, its characterized in that: one section of the top surface of the supporting bottom plate is an inclined plane, the other section of the top surface of the supporting bottom plate is a plane which is flush with the highest point of the inclined plane, and balls are installed on the plane in a rolling mode through ball grooves and supported at the bottom of the pedal through the balls.
The hydraulic jack pedal improves structure, its characterized in that: the top of the suspension beam is fixedly connected with a vertical guide rod, and the vertical guide rod penetrates through the top plate and is in relative sliding fit with the top plate.
The utility model discloses in, the footboard suspends the connecting piece in midair in the driving plate top through elasticity, and elasticity suspends in midair in the connecting piece by supporting baseplate support in the footboard bottom, and supporting baseplate is connected with vertical board, and vertical board is connected with vertical connecting rod, and vertical connecting rod can slide from top to bottom in the roof beam of suspending, and vertical connecting rod upper end is connected with the roof, is connected with supporting spring between roof and the roof beam of suspending. When the structure does not work, the pedal is suspended and supported by the supporting bottom plate, and the supporting spring can keep the pedal above the transmission plate without applying any force to the transmission plate,
compared with the prior art, the utility model discloses can not cause a small amount of oil intakes in the hydraulic ram when out of work to have the high advantage of pedal control precision at the during operation.
