[0033] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention. Example 1

[0034] like Figure 1-5As shown, in this embodiment, a vertical and horizontal dual-purpose jack is disclosed, including a swing shaft box assembly 10, a cylinder base assembly 20 and a working cylinder assembly 30, wherein the swing shaft box assembly 10 includes a box body 11 and a swing shaft 13, the box body 11 is connected to the cylinder base assembly 20, and the combination forms a closed cavity, the unloading valve 21 and / or the plunger pump 22 on the cylinder base assembly 20 is located in the cavity, a part of the swing shaft 13 is located in the cavity, and the part of the swing shaft 13 is configured to control the opening or closing of the unloading valve 21 and / or the plunger pump 22.

[0035] Specifically, the swing shaft 13 is connected to a pressure frame 15. The pressure frame 15 has an eagle's beak head 15a for pushing the valve stem 21a of the unloading valve 21. The pressure frame 15 is provided with a pressure wheel 112 at one end away from the eagle's beak head 15a. The pressure wheel 112 is used to press the plunger part 22a on the plunger pump 22. The pressure frame 15 is mounted on the swing shaft 13 via a second pin shaft 18. The second pin shaft 18 is mounted with a first cotter pin 19. The pressure frame 15 is provided with a first pin shaft 17 at one end away from the eagle's beak head 15a. The first pin shaft 17 is mounted with the pressure wheel 112 via a pressure wheel bushing 16. A mounting pillow block 12 is provided on one or both sides of the housing 11. One end or both ends of the swing shaft 13 extend out of the mounting pillow block 12. A swing shaft sleeve 111 is provided between the mounting pillow block 12 and the swing shaft 13.

[0036] Furthermore, in this embodiment, the vertical and horizontal dual-purpose jack includes three parts, namely, the swing shaft box assembly 10, the cylinder base assembly 20, and the working cylinder assembly 30, which are described as follows:

[0037] 1. Swing shaft box assembly 10: The swing shaft 13 box is located at the bottom end of the jack. There is an outward-protruding mounting block 12 on each side of the box body 11. These two mounting blocks 12 are used to install and connect the fixed end of the jack. That is, the vertical and horizontal dual-purpose jack is installed in the predetermined position by installing the mounting blocks 12. A swing shaft sleeve 111 is embedded in the hole of the mounting block 12, and the swing shaft 13 passes through the axis of the swing shaft sleeve 111. A pressure frame 15 is installed in the middle section of the swing shaft 13. The pressure frame 15 is fixed to the swing shaft 13 by a second pin 18 and finally locked by a first cotter pin 19. A first pin 17 is inserted into the side hole of the fork plate of the pressure frame 15, thereby fixing the pressure roller 112 and the pressure roller sleeve 16. The first pin 17 is locked by a second cotter pin 110. An eagle's beak 15a is provided in the opposite direction, and the eagle's beak 15a is used to push the valve stem 21a of the unloading valve 21. The swing shaft 13 extends out of both ends of the swing shaft box 13, and a horizontal shaft hole 13a is provided in each of the two shaft extensions. The shaft hole 13a is used to reconnect with the external mechanism and is set to transmit torque. It can be driven on one side or synchronously on both sides, and then four connecting screws 14 are used to connect and fix the box body 11 of the entire swing shaft box assembly 10 and the cylinder base assembly 20.

[0038] 2 Cylinder base assembly 20: This serves as the base of the working cylinder assembly 30 and houses the valve system for controlling oil supply and return. The valve system includes a one-way valve (not shown), a relief valve (not shown), a threaded plunger pump 22, and an unloading valve 21. The plunger portion 22a has a built-in return spring.

[0039] 3. Cylinder assembly 30: It comprises a piston (not shown), a piston rod 32, and a cylinder body 31. Cylinder body 31 comprises an inner barrel (not shown) and an outer barrel. The piston rod 32 is provided with a piston rod shaft hole 32a. The cylinder cap includes a sealing ring and other components, similar to those found in conventional jacks. In this embodiment, the space between the inner and outer barrels of cylinder body 31 serves as an oil reservoir. The main structure can be mechanically assembled or welded. The cylinder can be piston or plunger-type. The connection method for the end of piston rod 32 is also varied. This embodiment adopts a welded main body, meaning the inner barrel, outer barrel, and guide rod cap are welded together. The cylinder is a plunger-type, and the jack is fixed with hinged ends.

[0040] Working principle:

[0041] See also Figure 2 The figure shows the standby state of the jack. When the force F is applied to the swing shaft 13, the swing shaft 13 drives the pressure frame 15 and the pressure wheel 112 to swing in the same direction, thereby pushing the plunger part 22a in the plunger pump 22 to cause it to displace. The hydraulic fluid generated by the movement of the plunger part 22a acts on the piston of the inner cylinder through the built-in hydraulic system and pushes the piston rod 32 to push outward and perform work. After the force F is released, the pressure frame 15 is pushed back to the starting position by the rebound force of the return spring built into the plunger. The repeated swinging cycle pushes the piston rod 32 to the intended position.

[0042] When force is applied to the swing shaft 13 in the opposite direction F, the swing shaft 13 drives the pressure frame 15 to swing in the opposite direction. At this time, the pressure wheel 112 on the pressure frame 15 leaves the plunger end face, and the plunger portion 22a stops working. The hawk's beak 15a opposite the pressure frame 15 also swings. The hawk's beak 15a pushes the push rod of the unloading valve 21 to move a distance B, thereby opening the valve inside the unloading valve 21 and draining the liquid in the inner cylinder back to the oil tank. The piston and piston rod 32 move back under the action of the external force.

[0043] In the figure, A is a small spaced distance. When the swing shaft 13 is not working, the pressure wheel 112 and the eagle beak on the pressure frame 15 are in the starting position, so that the pressure wheel 112 and the eagle beak head 15a of the pressure frame 15 do not interact with the corresponding functional parts. In the figure, B is the actual action distance required by the set unloading valve 21 rod. R and α in the figure are used to set the plunger stroke, and the relevant values ​​can be set as needed.

[0044] See also Figure 5 If the jack axis is installed vertically, it is a vertical hydraulic jack; if the jack axis is installed horizontally, it is a hydraulic horizontal jack; if the jack axis is installed at any angle to the horizontal line or vertical line, it is an inclined hydraulic jack.

[0045] In another embodiment, a mobile machine is disclosed, including the vertical and horizontal dual-purpose jack described in this embodiment. The mobile machine includes a hand-pushed hydraulic lifting platform vehicle, a semi-automatic hydraulic lifting platform vehicle and a fully automatic hydraulic lifting platform vehicle, and the lifting platform vehicle is used to transport goods.

[0046] In other embodiments, a fixed machine is disclosed, including the vertical and horizontal dual-purpose jack described in this embodiment, and the fixed machine includes a fixed hydraulic lifting platform, for example, a lifting platform is installed at a fixed position for raising or lowering a load at the fixed position.
