Detailed implementation manners

[0028] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific implementation manners, structures, features, and their effects of the application according to the present utility model. In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0029] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] As Figure 1 shown, a vertical hydraulic support column assembly machine provided by an embodiment of the present utility model includes: a chassis 3, a pressing part, and a translation part;

[0031] The pressing part includes a frame 1 and a first hydraulic cylinder 2. The lower end of the frame 1 is fixedly connected to the chassis 3. The cylinder body of the first hydraulic cylinder 2 is fixedly installed at the upper end of the frame 1, and the piston rod of the first hydraulic cylinder 2 extends downward;

[0032] The translation part includes a second hydraulic cylinder 4 and a slide plate 5. The side wall of the cylinder body of the second hydraulic cylinder 4 is fixedly connected to the chassis 3. The piston rod of the second hydraulic cylinder 4 is connected to the end of the slide plate 5 for pushing the slide plate 5 to translate along the chassis 3 so that the slide plate 5 approaches or moves away from the frame 1.

[0033] The working process of the vertical hydraulic support column assembly machine is as follows:

[0034] When assembling the column, a hoisting device such as a crane is used to lift the column cylinder body and place it on the slide plate 5. Then, the piston rod of the second hydraulic cylinder 4 is driven to drive the slide plate 5 to approach the frame 1, so that the column cylinder body moves to directly below the first hydraulic cylinder 2, making the column cylinder body and the first hydraulic cylinder 2 coaxial;

[0035] On this basis, first, the port of the column guide sleeve is docked with the upper port of the column cylinder body, and then the first hydraulic cylinder 2 is started. The piston rod of the first hydraulic cylinder 2 presses downward on the guide sleeve;

[0036] After the guide sleeve is pushed, the piston rod of the first hydraulic cylinder 2 rises, and then the column piston rod is connected to the upper port of the column cylinder body, and then the first hydraulic cylinder 2 is started again, and the piston rod of the first hydraulic cylinder 2 presses the column piston rod downward;

[0037] Through the above process, the column guide sleeve, piston rod and cylinder body are assembled together to complete the assembly of the hydraulic column.

[0038] In the technical solution of the present invention, during the above-mentioned assembly process, the piston rod and the guide sleeve are respectively connected to the cylinder body in the upper and lower parts. Compared with the horizontal disassembly and assembly machine, it is easier to use the assembly machine.

[0039] like Figure 1 and Figure 4 As shown, specifically, it also includes a sleeve 6. The free end of the piston rod of the first hydraulic cylinder 2 is fixedly connected to the pressing column 7. The pressing column 7 is threadedly connected to the upper end of the sleeve 6, so that the lower end of the sleeve 6 is pressed against the upper end of the column guide sleeve, making it easier to completely press the guide sleeve into the column cylinder body.

[0040] Specifically, the cylinder body of the second hydraulic cylinder 4 is horizontally fixed on the upper surface of the chassis 3 , and the side walls of the cylinder body of the second hydraulic cylinder 4 are fixed to the chassis 3 by bolts.

[0041] Specifically, in order to reduce the height of the hydraulic column hoisted by the workshop crane, the chassis 3 is placed in a deep pit on the workshop floor. When assembling the hydraulic column, the hydraulic column is hoisted in the deep pit.

[0042] like Figure 1 and Figure 2 As shown, in a specific embodiment, the piston rod of the second hydraulic cylinder 4 is hinged to the end of the slide plate 5.

[0043] In this embodiment, specifically, the piston rod of the second hydraulic cylinder 4 is hinged to the waist hole 10 of the ear plate 8 at the end of the skateboard 5 through a pivot 9 (the length direction of the waist hole 10 is along the vertical direction). In the process of the piston rod of the second hydraulic cylinder 4 driving the skateboard 5 to move horizontally, even if the upper surface of the chassis 3 is uneven, the height of the chassis 3 fluctuates slightly when the skateboard 5 moves along the upper surface of the chassis 3. The pivot 9 can move up and down in the waist hole 10, and the ear plate 8 at the end of the skateboard 5 will not exert a vertical force on the piston rod, thereby avoiding the piston rod of the second hydraulic cylinder 4 from bending itself.

[0044] like Figure 1 and Figure 3 As shown, in a specific embodiment, it also includes a plurality of rollers 11. The upper surface of the chassis 3 is provided with a groove, and the plurality of rollers 11 are arranged in the groove in sequence. The arrangement direction of the plurality of rollers 11 is the same as the translation direction of the skateboard 5.

[0045] In this embodiment, when the piston rod of the second hydraulic cylinder 4 drives the sliding plate 5 to translate, the sliding plate 5 contacts with a plurality of rollers 11, and the sliding plate 5 and the rollers 11 have rolling friction, with a relatively small friction coefficient and relatively small resistance for the movement of the sliding plate 5.

[0046] As Figure 1 and Figure 3 shown, in a specific embodiment, the groove and the frame 1 are staggered from each other.

[0047] In this embodiment, specifically, the horizontal positions of the groove (roller 11) and the frame 1 are staggered from each other, the groove is located between the second hydraulic cylinder 4 and the frame 1. When the sliding plate 5 is not directly below the first hydraulic cylinder 2, the sliding plate 5 contacts with a plurality of rollers 11 and has rolling friction.

[0048] When the sliding plate 5 moves to directly below the first hydraulic cylinder 2, the sliding plate 5 and the chassis 3 have sliding friction, and the sliding plate 5 and the chassis 3 form surface-to-surface contact.

[0049] When the piston rod of the first hydraulic cylinder 2 extends downward to press against the piston rod or the guide sleeve of the column, the sliding plate 5 is under pressure and is also fully supported by the chassis 3.

[0050] This embodiment greatly reduces the frictional resistance of the sliding plate 5 and also avoids damage to the rollers 11.

[0051] As Figure 1 shown, in a specific embodiment, the side of the sliding plate 5 is fixedly connected to a magnet 12, and the inner side of the lower end of the frame 1 is fixedly connected to a Hall element 13.

[0052] In this embodiment, the Hall element 13 is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the hydraulic oil pump in the oil circuit where the second hydraulic cylinder 4 is located. When the piston rod of the second hydraulic cylinder 4 pushes the sliding plate 5 towards the frame 1, when the magnet 12 and the Hall element 13 are opposite to each other, the column cylinder body and the first hydraulic cylinder 2 are coaxial. The Hall element 13 sends an electrical signal to the controller, and the controller sends a stop command to the hydraulic oil pump. The hydraulic oil pump in the oil circuit where the second hydraulic cylinder is located stops operating, and the piston rod of the second hydraulic cylinder stops extending.

[0053] As Figure 2 shown, in a specific embodiment, the upper surface of the sliding plate 5 is provided with a plurality of concentric circles 14, the first diameter 15 of the concentric circles 14 is perpendicular to the side of the sliding plate 5, and the magnet 12 is located on the extension line of the first diameter 15.

[0054] In this embodiment, specifically, the central axes of the Hall element 13 and the first hydraulic cylinder 2 are located on the central plane of the frame 1 (the frame 1 is symmetric about the central plane). The multiple concentric circles 14 on the sliding plate 5 are used to correspond to column cylinders with different diameters. When the column cylinder is placed on the sliding plate 5, the first diameter 15 of the bottom end surface of the column cylinder also passes through the magnet 12. That is, when the magnet 12 and the Hall element 13 correspond to each other, the axis of the column cylinder coincides with the central axis of the first hydraulic cylinder 2. Thus, through the corresponding relationship between the Hall element 13 and the magnet 12, it is ensured that the piston rod of the first hydraulic cylinder 2 can accurately press against the piston rod and the cylinder body of the column.

[0055] As Figure 1 and Figure 3 shown, in the specific embodiment, there are also two hydraulic clamping members 16, and the two hydraulic clamping members 16 are respectively arranged on the relative inner sides of the frame 1.

[0056] In this embodiment, specifically, each hydraulic clamping member 16 includes a third hydraulic cylinder 1601 and a clamping claw 1602. The third hydraulic cylinder 1601 is fixedly connected to the inner side wall of the frame 1, the piston rod of the third hydraulic cylinder 1601 is fixedly connected to the clamping claw 1602, and the clamping claw 1602 is arc-shaped to facilitate the clamping claw 1602 to fit against the axial side wall of the column cylinder.

[0057] As Figure 5 shown, in the specific embodiment, the opposite ends of the lower surface of the sliding plate 5 are designed with rounded corners.

[0058] In this embodiment, specifically, in the translation direction of the sliding plate 5, the opposite ends of the lower surface of the sliding plate 5 are designed with rounded corners to prevent the opposite ends of the lower surface of the sliding plate 5 from being too sharp and scratching the upper surface of the chassis 3.

[0059] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
