The bottom plate connection holes 131 of one standard section 1 are detachably fixedly connected with the top plate connection holes 121 of another standard section 1 by bolts, so that the top and bottom stacking and fixing can be realized.

[0030] To facilitate installation, in the present embodiment, a plurality of upwardly protruding positioning plug-in protrusions 122 are arranged at intervals around the top of each standard section 1, and a plurality of upwardly recessed positioning plug-in grooves 132 are arranged at intervals around the bottom of each standard section 1, and the positioning plug-in protrusions 122 correspond to the positioning plug-in grooves 132 one by one; for two standard sections 1 stacked up and down, the positioning plug-in protrusions 122 of the standard section 1 located at the bottom are inserted into the positioning plug-in grooves 132 of the standard section 1 located at the top.

[0031] The inner frame connection part of the inner frame 3 includes: a plurality of inner frame connection holes 32 opened on the inner frame 3, and the inner frame connection holes 32 are located on the inner frame 3 on both sides of the front and rear of the standard node inlet 23; the standard node body connection part of each standard node 1 includes: a plurality of standard node connection holes 111 opened on the standard node body 11, and the setting position of the standard node connection holes 111 ensures that when the standard node is located in the bottom outer frame 22, the standard node connection holes 111 are arranged on the standard node body 11 on both sides of the front and rear of the standard node inlet 23, and when the inner frame 3 is set on the outer state of the standard node 1, the inner frame connection holes 32 correspond to the standard node connection holes 11 one by one, and the corresponding inner frame connection holes 32 and the standard node connection holes 111 can be penetrated by a pin 6 for detachable fixation. The bottom outer frame 22 is provided with an outer frame working port 24 for facilitating the connection between the standard node 1 and the inner frame 3, and the inner frame 3 is provided with an inner frame working port 33 for facilitating the connection between the standard node 1 and the inner frame 3.

[0032] like Figure 6 , Figure 7 , Figure 8 As shown, in this embodiment, the support module 5 comprises: a support module body 51, a support module top plate 52 is arranged on the top of the support module body 51, a support module bottom plate 53 is arranged on the bottom of the support module body 51, a support module connection hole 531 is opened on the support module bottom plate 53, and the support module connection hole 531 corresponds to the top plate connection hole 121 on the standard section 1; the support module connection hole 531 on the support module 5 is used to be bolted and fixed with the top plate connection hole 121 on the standard section 1. The support structure of the top of the support module 5 comprises: a circular support hole 521 is opened on the support module top plate 52, and a spherical support 522 is arranged inside the support module body 51 below the circular support hole 521, and the support module of this structure is used to support the spherical surface. Or the support structure of the top of the support module 5 comprises: a pair of baffles 54 are arranged on the support module top plate 52, and a blocking gap 541 for blocking pipe fittings is formed between the pair of baffles 54, and the support module of this structure is used to support pipe fittings. In this embodiment, a pair of baffles 54 are detachably connected to the support module top plate 52, so when the plane needs to be supported, only the baffles 54 need to be removed, and the support module top plate 52 can directly support the plane.

[0033] Also for the convenience of installation, a number of upwardly recessed support connection grooves 532 are arranged at intervals around the bottom of the support module body 51. After stacking, the positioning plug-in protrusion 122 on the standard section 1 at the top position can be correspondingly inserted into the support connection groove 532 at the bottom of the support module 5 located above it.

[0034] The working principle is as follows: when it is necessary to lift equipment or buildings, the bottom support seat 21 of the bottom outer frame 2 is first fixed below the lifting position, and the hydraulic cylinder 4 is installed on the bottom support seat 21, and the driving rod of the hydraulic cylinder 4 is connected to the lifting support plate 31 of the inner frame 3.

[0035] Install the support module 5 on the first standard section 1. If the contact surface of the component to be lifted is a spherical surface, select a support module for supporting a spherical surface. If the contact surface of the component to be lifted is a pipe structure, select a support module for supporting pipe-like components. If the contact surface of the component to be lifted is a plane structure, directly select a support module for supporting a spherical surface, or select a support module after removing a pair of baffles 54 on the support module for supporting pipe-like components.

[0036] The support module 5 is stacked on top of the first standard section 1, and the positioning plug-in protrusion 122 on the standard section 1 is inserted into the support connection groove 532 at the bottom of the support module 5, and the support module connection hole 531 on the support module 5 is fixed with the top plate connection hole 121 on the standard section 1 by bolts. The first standard section will also be the highest standard section after being stacked one by one.

[0037] The hydraulic cylinder 4 first drives the inner frame 3 to move upward to ensure that the first standard section 1 with the support module 5 installed can enter through the standard section entrance 23, and then uses a forklift to deliver the first standard section 1 with the support module 5 installed into the bottom outer frame 22 through the standard section entrance 23; the hydraulic cylinder 4 then drives the inner frame 3 to fall back into the bottom outer frame 22 and fit outside the first standard section 1. In this state, a pin 6 is inserted between the corresponding inner frame connection hole 32 and the standard section connection hole 111, and the two are detachably fixed by the pin 6. The setting of the outer frame working port 24 and the inner frame working port 33 facilitates the operation and observation of the fixed connection.

[0038] Next, the hydraulic cylinder 4 drives the inner frame 3 to move upward, and at this time the inner frame 3 will move upward together with the first standard section 1 with the support module 5, and the component at the jacking position will be supported on the supporting part of the support module 5 and thus lifted up, until there is enough space for the entry of the second standard section, and the forklift will send the second standard section into the bottom outer frame 22 through the standard section entrance 23, and the hydraulic cylinder 4 drives the first standard section 1 downward so that the positioning plug-in protrusion 122 of the standard section 1 located below is inserted into the positioning plug-in groove 132 of the standard section 1 located above, and then the bottom plate connecting hole 131 of the standard section 1 located above and the top plate connecting hole 121 of the standard section 1 located below are detachably fixed by bolts, so that the upper standard section is supported and fixedly connected to the lower standard section, thereby realizing the upper and lower stacking and fixing, and continuously raising the jacking height.

[0039] Then remove the pin 6 between the inner frame connecting hole 32 and the standard joint connecting hole 111, so that the hydraulic cylinder 4 can drive the inner frame 3 to move downward and fall back into the bottom outer frame 22, and be sleeved on the outside of the second standard joint. In this state, the pin 6 is passed between the corresponding inner frame connecting hole 32 and the standard joint connecting hole 111, and the inner frame and the second standard joint are detachably fixed by the pin 6.

[0040] Continue to repeat the above actions until the components on the supporting module 5 are lifted to the required height.

[0041] The above working process is only a description of the support process at one position. Usually, a device or a building needs support at multiple positions. The support process at each position is the same as described above, and can be performed separately or simultaneously at multiple positions. The device or building to be lifted needs to be lifted to a certain height in advance using a lifting device or a lifting device to ensure that the bottom outer frame can be installed and the first standard energy-saving module with the support module installed can enter the bottom outer frame.

[0042] From the above structure introduction and the working process introduction, it can be seen that the jacking device described in this application has the following advantages: the structure is simple but very clever, but stable and reliable. A lifting drive mechanism and a standard section entrance 23 for the standard section to enter and exit are set on the bottom support frame 2, and an inner frame 3 is set in the bottom support frame 2. Each standard section 1 can move upward in the inner frame to enter the bottom support frame 2 after leaving enough height for a standard section to enter, and then the inner frame falls back and is sleeved outside the standard section. Since the inner frame and the standard section can be connected by a detachable connecting mechanism, when the two are connected, the lifting drive mechanism can lift the inner frame and the standard section upward together, and then send the second standard section into the bottom support frame 2, support it below the previous standard section, and then lift the next standard section through the inner frame to achieve continuous stacking of the standard sections for jacking. Each time the lifting drive mechanism rises upward, it only needs to ensure the entry of the next standard energy-saving device. This reduces the travel requirements of the lifting mechanism, greatly improves safety and reliability, and effectively reduces the energy consumption of the lifting drive mechanism. This greatly facilitates the connection and disassembly between the inner frame and the standard section, and also greatly facilitates the connection operation between the upper and lower standard sections, thereby greatly facilitating the jacking operation and greatly improving the safety of the jacking work. The number of staff can also be effectively reduced, which effectively reduces the cost of the jacking work.
