DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0018] Embodiment 1:

[0019] like Figure 1 and Figure 2 As shown, Figure 1 It is a schematic diagram of the overall structure of a double-section hydraulic lifting column. Figure 2 It is a cross-sectional view of the lifting cylinder 107. The utility model provides a double-section hydraulic lifting column: including an embedded cylinder 101, an electric control box 102 and an auxiliary mechanism.

The above scheme can realize that when in use, the micro hydraulic station 104 can be integrated with the embedded cylinder 101, effectively reducing the length of the oil pipe, which is beneficial to the laying of the oil pipe and subsequent maintenance and overhaul. It can be understood that the above scheme can be beneficial to the laying of the oil pipe and subsequent maintenance and overhaul.

[0020] In this embodiment, the embedded cylinder 101 has an oil pipe through hole 103, and the oil pipe through hole 103 is located below the embedded cylinder 101. The electric control box 102 is fixedly connected to the embedded cylinder 101 and is located on the side of the embedded cylinder 101 close to the oil pipe through hole 103. The oil pipe through hole 103 will facilitate the passage of the working oil pipe. The electric control box 102 is installed on the embedded cylinder 101 by bolts, and the control electrical equipment is arranged inside. Four fixing ears with holes are arranged at the bottom of the embedded cylinder 101, which are convenient for fixing by anchor bolts during pre-embedding.

[0021] Among them, the micro hydraulic station 104 is fixedly connected to the embedded cylinder 101, and is electrically connected to the electric control box 102, and is located at the bottom of the embedded cylinder 101; the hydraulic cylinder 105 is fixedly connected to the embedded cylinder 101, and is connected to the micro hydraulic station 104 through an oil pipe, and is located in the embedded cylinder 101; the limit seat 106 is fixedly connected to the embedded cylinder 101 and is located at the top of the embedded cylinder 101; the lifting cylinder 107 is slidably connected to the embedded cylinder 101, the lifting cylinder 107 is slidably connected to the limit seat 106, and is connected to the output end of the hydraulic cylinder 105, and is located on the side of the hydraulic cylinder 105 close to the embedded cylinder 101; the top cover 108 is fixedly connected to the lifting cylinder 107, and is located at the top of the lifting cylinder 107; the locking device is arranged on the side of the output end of the hydraulic cylinder 105 close to the lifting cylinder 107. The micro hydraulic station 104 is installed on the bottom platform of the embedded cylinder 101 by bolts, and is electrically connected to the electric control box 102 by cables. The hydraulic cylinder 105 is installed at the bottom of the storage cavity of the embedded cylinder 101 by hexagon socket bolts, and is connected to the hydraulic valve group equipped on the micro hydraulic station 104 by oil pipes. The oil pipes are pressure-resistant copper pipes and can pass through the oil pipe through holes 103 when connected. The limit seat 106 is installed on the top of the embedded cylinder 101 by hexagon socket bolts, and the bolts are installed by countersunk heads. The cross-section of the lifting cylinder 107 is T-shaped, and its bottom sliding part can slide in the storage cavity of the embedded cylinder 101. The top cylindrical end can slide with the limit seat 106. The output end of the hydraulic cylinder 105 is connected to the lifting cylinder 107 through the locking device, and the top cover 108 is installed on the top of the lifting cylinder 107 by hexagon socket bolts, and the bolts are installed by countersunk heads.

[0022] Secondly, the sealing ring 109 is detachably connected to the limiting seat 106, and is slidably connected to the lifting cylinder 107, and is sleeved on the outside of the lifting cylinder 107. An installation groove is provided on the inner wall of the matching through hole of the limiting seat 106 to facilitate the installation of the sealing ring 109. After the sealing ring 109 is installed, it is sleeved on the outside of the lifting cylinder 107 to facilitate sealing and reduce impurities from entering the embedded cylinder 101.

[0023] Then, the first wire ring 110 is threadedly connected to the output end of the hydraulic cylinder 105 and is located on the side of the hydraulic cylinder 105 close to the lifting cylinder 107; the second wire ring 111 is threadedly connected to the output end of the hydraulic cylinder 105 and is located on the top of the first wire ring 110. A stepped shaft is arranged at the top of the piston rod of the hydraulic cylinder 105, and the end of the stepped shaft is an external hexagonal end, and an external threaded end is arranged at the top of the external hexagonal end, so that the first wire ring 110 and the second wire ring 111 are conveniently installed in sequence, and the lifting cylinder 107 is provided with an external hexagonal hole for easy matching, so that during installation, the piston rod of the hydraulic cylinder 105 is prevented from rotating to affect the installation of the first wire ring 110 and the second wire ring 111.

After the micro hydraulic station 104 generates hydraulic power, it can drive the hydraulic cylinder 105 to move to extend or retract, so as to realize the lifting of the lifting cylinder 107. When the hydraulic cylinder 105 is fully extended, the upper end surface of the cylindrical end of the bottom of the lifting cylinder 107 just abuts against the lower end surface of the limit seat 106. At this time, the lifting cylinder 107 can achieve a blocking effect. When the hydraulic cylinder 105 is fully retracted, the lifting cylinder 107 will Retracted into the embedded cylinder 101, the upper surface of the top cover 108 will be flush with the upper surface of the limit seat 106, and there is a safe distance between the bottom of the lifting cylinder 107 and the embedded cylinder 101. At this time, the oil pipe will automatically avoid through the avoidance cavity inside the lifting cylinder 107 to avoid breakage or extrusion deformation. Furthermore, after the micro hydraulic station 104 is integrated and installed on the embedded cylinder 101, the length of the oil pipe connected to the hydraulic cylinder 105 can be significantly shortened, thereby reducing the scope of maintenance and inspection. At the same time, a single lifting column can realize a single function and is more stable, so that when in use, the micro hydraulic station 104 can be integrated with the embedded cylinder 101, effectively reducing the length of the oil pipe, which is beneficial to the laying of the oil pipe and subsequent maintenance and inspection.
