Embodiment Construction

[0009] The present invention is described in further detail below in conjunction with the embodiment given with accompanying drawing.

[0010] refer to figure 1 , a reciprocating motion device that can produce multiple times the stroke of the oil cylinder, a pulley frame 2 driven and connected by a frame 1, an oil cylinder 7 arranged on the frame 1, and two sets of pulley mechanisms symmetrically arranged between the frame 1 and the pulley frame 2 It is composed of a slide plate 4 that is driven and connected to the pulley mechanism to reciprocate up and down along the frame 1 slideway; each set of pulley mechanisms is formed in the following manner: two pulleys 3 are respectively arranged at the upper and lower ends of the frame 1, The upper and lower sides of the pulley frame 2 are respectively provided with the same number of pulleys 3, and one end of the rising steel rope 5 is fixedly connected to the upper end of the frame 1, and the other end is from a pulley on the uppe...

Abstract

The invention relates to a linear reciprocating motion mechanism which adopts the hydraulic pressure as the power source, in particular to a reciprocating motion device which can generate a plurality of times of cylinder displacements. The reciprocating motion device comprises a frame, a pulley frame which is arranged on the frame and is in driving connection with the oil cylinder, two groups of pulley mechanisms symmetrically arranged between the frame and the pulley frame, and a sliding plate which is in driving connection with the pulley mechanisms and able to move up and down repeatedly along the frame slide way. The reciprocating motion device realizes that a single oil cylinder with smaller displacement is adopted to generate the large displacement reciprocating motion which is a plurality of times of the cylinder displacements so that the whole length of the moving machine is shortened; the reciprocating motion device is applicable to various operating sites in need of large displacement lifting or large displacement transverse effect, and has the advantages of simple structure, low cost, reliability, durability and having the acceleration effect.

Description

technical field [0001] The invention relates to a linear reciprocating motion driving mechanism with hydraulic pressure as a power source, in particular to a driving mechanism capable of producing reciprocating motion that is multiple times the stroke of an oil cylinder. Background technique [0002] Generally, the hydraulic cylinder is used as the power source of the linear reciprocating drive mechanism. The stroke of the linear motion of the drive mechanism is the working stroke of the cylinder piston. Therefore, the larger the required working stroke, the longer the effective stroke of the cylinder is required, which will inevitably increase The length of the oil cylinder and the overall structural size of the driving mechanism are increased. It is difficult to directly and simply use the hydraulic cylinder as the driving mechanism of the power source when the working environment is limited but a large working stroke is required. Contents of the invention [0003] The ...
