In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0022] In the prior art, the electric hydraulic lifting column is installed in the embedded hole, and the concrete is filled around the electric hydraulic lifting column, but the concrete and the electric hydraulic lifting column do not form a mutual fastening force, so that the electric hydraulic lifting column is easily inclined after being impacted in the raised state, and the security effect cannot be achieved.

[0023] In order to solve the above problems, the utility model provides an electric hydraulic lifting column, including embedded bucket 1, power component 2 and column body 3, power component 2 installs at embedded bucket 1 bottom, power component 2 includes telescopic link 21, telescopic link 21 is perpendicular to embedded bucket 1 axis movement, telescopic link 21 is installed with column body 3, embedded bucket 1 outside sleeve joint has reinforcing rib 4, reinforcing rib 4 is formed with frame on it, and the concrete is filled in the frame. Figs. 1 to 3

[0024] The concrete enters the frame and is filled, so that the concrete enters the inside of the reinforcing rib 4, thereby increasing the contact area of the concrete and the electric hydraulic lifting column as a whole, and the concrete entering the inside of the reinforcing rib 4 can provide a limit for the electric hydraulic lifting column. When the electric hydraulic lifting column has a tendency to tilt, the concrete entering the frame can limit the electric hydraulic lifting column, making the electric hydraulic lifting column more stable, improving its impact resistance, and improving the security capability of the electric hydraulic lifting column.

[0025] The reinforcing rib 4 includes a first annular beam 41 and a second annular beam 42, the second annular beam 42 is installed on the lower side of the first annular beam 41, and the first annular beam 41 and the second annular beam 42 are connected by a stud 43. The first annular beam 41, the second annular beam 42 and the stud 43 form a frame.

[0026] The reinforcing rib 4 has a plurality of studs 43 installed therein, and the concrete is fastened with the reinforcing rib 4 when entering the frame. The first annular beam 41 and the second annular beam 42 are relatively simple in processing form, and can be welded together by the stud 43 to reduce processing cost.

[0027] The telescopic link 21 is provided with a support piece 5, the support piece 5 is provided with a first screw hole, the column body 3 is provided with a second screw hole, and a fixing bolt is screwed into the first screw hole through the second screw hole.

[0028] The column body 3 and the telescopic link 21 are connected in a separated form. When the inside of the embedded bucket 1 needs to be repaired, the fixing bolt is unscrewed, the support piece 5 and the top of the column body 3 are separated, and then the column body 3 can be directly taken out. The parts in the embedded bucket 1 can be taken out separately, the weight of single taking-out is reduced, and the parts can be taken out manually, thereby reducing the maintenance cost and difficulty. Meanwhile, the base 6 and the tray 8 are connected by bolts or other fastening forms, and the power component 2 in the inside can be directly taken out after the bolts or fasteners are removed.​

[0029] The power component 2 includes a hydraulic cylinder 22, a drive motor 23, and a telescopic rod 21. A base 6 is formed on the lower side of the hydraulic cylinder 22, the drive motor 23 is mounted on the side of the base 6, and the telescopic rod 21 is mounted on the upper side of the base 6. A pipeline is provided inside the base 6, and the hydraulic cylinder 22 is connected to the telescopic rod 21 through the pipeline. The drive motor 23 drives the hydraulic fluid in the pipeline to flow, pushing the telescopic rod 21 to move up and down. The method of using the hydraulic cylinder 22 to drive the extension rod inside the telescopic rod 21 to move the column 3 is existing technology, and its technical principle has been disclosed and will not be elaborated here.

[0030] The drive motor 23 of this utility model is installed on the side of the base 6 and does not occupy the axial direction of the telescopic rod 21, thereby saving space in the height direction. When the extension length of the column 3 is the same, the height of the pre-embedded bucket 1 can be reduced, making the structure of the electric hydraulic lifting column more compact, the depth of the pre-embedded hole shallower, and reducing the installation difficulty.

[0031] A flange 11 is installed on the upper side of the pre-embedded bucket 1, and a column 3 is installed inside the flange 11. A limit rod 12 is installed on the lower side of the flange 11, and a limit ring 31 is installed on the lower side of the column 3. The limit ring 31 passes through the limit rod 12. By installing the limit rod 12, the column 3 can remain stable during the movement and will not shake.

[0032] The bottom of the pre-embedded bucket 1 is equipped with a support column 7, and a tray 8 is installed on the support column 7. A power component 2 is installed on the upper side of the tray 8. By adding the tray 8, the installation height of the hydraulic cylinder 22 and the drive motor 23 can be increased, avoiding groundwater from corroding the drive motor 23 and other components, and improving the reliability of the electric hydraulic lifting column. Liquid can be discharged from the drain port on the lower side of the tray 8.

[0033] A buffer component is installed on the tray 8, which abuts against the column 3. The buffer component is made of flexible material. If the speed at which the cylinder 22 drives the telescopic rod 21 to move is too fast, the column 3 will hit the tray 8 and cause a lot of noise. By adding a flexible material to the tray 8, the noise generated by the column 3 hitting the tray 8 can be reduced, thereby improving the quality of use of the electric hydraulic lifting column. The flexible material is usually a rubber pad, etc.

[0034] A fixing plate 9 is attached to the inner wall of the pre-embedded bucket 1. The fixing plate 9 is U-shaped and forms a wire groove with the inner wall of the pre-embedded bucket 1. Wires are installed in the wire groove. An opening 13 is provided on the side of the pre-embedded bucket 1 near the reinforcing rib 4. A junction box 10 is installed on the outside of the opening 13. A drain plug is installed on the junction box 10, and a wire is threaded through the drain plug.

[0035] The wires are protected by being routed inside the embedded barrel 1, and after the wires are drawn out of the opening 13, they enter the junction box 10, which is fitted with a waterproof plug that fits tightly with the wires to prevent external water from entering the junction box 10, keeping the inside of the embedded barrel 1 dry and reducing the probability of damage to the parts. At the same time, the wires are drawn out of the top of the embedded barrel 1, and when the wires are replaced, the position at which the wires are drawn out is kept level with the position at which the wires are drawn out of the embedded barrel 1, reducing the number of times the wires are bent inside the conduit in the concrete and avoiding damage to the wires, improving the reliability of the hydraulic lifting column.

[0036] The embedded barrel 1, the reinforcing rib 4, the tray 8 and the surface of the column body 3 are galvanized, which reduces the corrosion of the hydraulic lifting column by the external environment and improves the reliability of the hydraulic lifting column.
