Embodiment 1

[0027] Such as Figure 1-Figure 3 As shown, a hydraulic jacking device that can move forward and backward is characterized in that it includes a jacking mechanism 1, and the jacking mechanism 1 includes a bottom connecting plate 18, and a rectangular bottom bracket 11 is arranged above the bottom connecting plate 18. , the bottom connecting plate 18 is connected with the front and rear displacement mechanism 2, the two long sides corresponding to the bottom bracket 11 are provided with chute 12, and a short side of the bottom bracket 11 is provided with a hydraulic cylinder 13, and the output of the hydraulic cylinder 13 The shaft 131 is connected with a drive link 14, the two ends of the drive link 14 are provided with a slide block 15, the slide block 15 is located in the chute 12 and can move along the length direction of the chute 12, the drive link 14 A lifting support 16 is connected to the top, and a lifting plate 17 is provided above the lifting support 16 .

Embodiment 2

[0029] On the basis of Embodiment 1, the lifting bracket 16 includes two sets of lifting assemblies, the lifting assembly includes a first connecting rod 161 and a second connecting rod 162, one end of the first connecting rod 161 is hinged to the driving connecting rod 14 , the other end of the first connecting rod 161 is hinged to the bottom of the lifting plate 17, one end of the second connecting rod 162 is hinged to the inner side of the bottom bracket 11, and the other end of the second connecting rod 162 is hinged to the bottom of the lifting plate 17, so The middle part of the first connecting rod 161 and the second connecting rod 162 is hinged.

Embodiment 3

[0031] On the basis of Embodiment 2, the lengths of the first connecting rod 161 and the second connecting rod 162 are the same.

Abstract

The invention discloses a hydraulic jacking device capable of moving back and forth, comprising a jacking mechanism, the jacking mechanism includes a bottom connecting plate, a rectangular bottom bracket is arranged above the bottom connecting plate, a front and rear displacement mechanism is connected under the bottom connecting plate, and the bottom bracket There are slide grooves on the corresponding two long sides, a hydraulic cylinder is provided on one short side of the bottom bracket, and a drive link is connected to the output shaft of the hydraulic cylinder, and sliders are provided at both ends of the drive link. The slot can move along the length direction of the chute, the driving link is connected with a lifting bracket, and a lifting plate is arranged above the lifting bracket; the invention realizes the lifting of the lifting plate through a hydraulic cylinder arranged horizontally, and only one hydraulic pressure is needed. The cylinder can achieve a stable lifting effect. By setting the front and rear displacement mechanism under the bottom connecting plate, the lifting operation can be performed at different positions without moving the whole device, which is more convenient to use.

Description

technical field [0001] The invention relates to the field of hydraulic devices, in particular to the manufacture of a hydraulic jacking device capable of moving back and forth. Background technique [0002] At present, there are few developments and applications of hydraulic jacking devices for oil cylinders in China. The existing hydraulic jacking devices need to move the whole device when jacking up different positions, which is extremely inconvenient to use. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulic jacking device that can move back and forth in order to solve the problem that the existing hydraulic jacking device needs to move the whole device when jacking up different positions and is extremely inconvenient to use. [0004] The technical scheme that the present invention adopts is as follows: [0005] A hydraulic jacking device capable of moving back and forth, including a jacking mechanism, the jacking mechanis...
