[0037] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] like Figures 1 to 3 As shown, this embodiment provides a lattice shell structure support device, including a fixed base 1, a support assembly 2 and two driving mechanisms 3. Among them, the fixed base 1 is configured to be supported on the ground, the support assembly 2 includes a support member 21, a top plate 22 and a limit member 23, the support member 21 is adjustably arranged on the fixed base 1 in the vertical direction, the top plate 22 is arranged at one end of the support member 21 away from the fixed base 1, the limit member 23 is arranged on the top plate 22, and the lattice shell structure to be supported abuts on the limit member 23. The two driving mechanisms 3 are arranged on both sides of the support assembly 2, the fixed end of the driving mechanism 3 is fixed on the fixed base 1, and the output end is connected to the support member 21. Under the synchronous drive of the two driving mechanisms 3, the support member 21 can be lifted and lowered in the vertical direction so that the limit member 23 abuts against the lattice shell structure. The support device can be applied to the support of lattice shell structures with different slopes, and has high versatility; at the same time, the operation is simple and convenient, which is conducive to improving construction efficiency.

[0039] Exemplarily, the driving mechanism 3 is a driving motor commonly used in the art, as long as it can drive the supporting member 21 to rise and fall in the vertical direction relative to the fixed base 1 .

[0040] Alternatively, if Figure 1 and Figure 2 As shown, the fixed base 1 includes a fixed plate 11 and a fixed frame 12. The fixed plate 11 is configured to be supported on the ground. The fixed frame 12 is fixed on the fixed plate 11. A slide groove extending in the vertical direction is provided on the fixed frame 12. The support member 21 is adjustable in position in the slide groove. The slide groove can provide a certain guiding effect for the lifting and lowering of the support member 21, thereby ensuring the smoothness and stability of the movement of the support member 21. In addition, the setting of the fixed frame 12 can not only ensure the stability of the support, but also reduce the deadweight of the support device, which is convenient for transportation during construction.

[0041] Furthermore, if Figure 3 As shown, the support member 21 includes a web 211 and two wing plates 212 respectively arranged on both sides of the web 211, and the web 211 and the two wing plates 212 are connected to the top plate 22. A slide groove is respectively arranged on the opposite sides of the fixed frame 12, and the two wing plates 212 are arranged in the two slide grooves in a one-to-one correspondence and adjustable position, and the output ends of the two driving mechanisms 3 are connected to the two wing plates 212 in a one-to-one correspondence. With the above arrangement, the two wing plates 212 are synchronously driven to move in the vertical direction by the two driving mechanisms 3 to realize the lifting and lowering of the top plate 22 and the limiter 23, thereby ensuring the stability during the lifting and lowering process.

[0042] Furthermore, if Figure 1 and Figure 2 As shown, a first fixing seat 4 is provided on the fixing plate 11, a second fixing seat 5 is provided on the wing plate 212, a fixing end of the driving mechanism 3 is provided on the first fixing seat 4, and an output end of the driving mechanism 3 is connected to the second fixing seat 5. The driving mechanism 3 is a component with relatively large losses, and the above arrangement can facilitate the replacement and maintenance of the driving mechanism 3.

[0043] Exemplarily, the fixed end of the driving mechanism 3 is detachably connected to the first fixing seat 4 by bolts, and the output end of the driving mechanism 3 is also detachably connected to the second fixing seat 5 by bolts.

[0044] Optionally, the support device also includes a control component, which is communicatively connected to the two driving mechanisms 3 and can control the synchronous opening and closing of the two driving mechanisms 3, so that the lifting and lowering operations of the support member 21 are more convenient and efficient, which is conducive to further improving construction efficiency.

[0045] Specifically, the control unit is a single chip microcomputer disclosed in the prior art, on which a relevant control program is burned, and combined with the control program, the opening and closing of the driving mechanism 3 is controlled. Exemplarily, the single chip microcomputer is an STM32 controller, and the relevant control program refers to the prior art.

[0046] Alternatively, if Figure 1 and Figure 3 As shown, the support assembly 2 also includes a positioning member 24. The fixed frame 12 is provided with a plurality of first fixing holes spaced apart in the vertical direction, and the web 211 is provided with at least one second fixing hole, and the positioning member 24 is inserted through any of the first fixing hole and the second fixing hole. When the driving mechanism 3 raises the support member 21 to the required height, the positioning member 24 is inserted through the first fixing hole and the second fixing hole to fix the support member 21 on the fixed frame 12, thereby ensuring stability during the subsequent construction of the lattice shell structure and ensuring the safety of the construction operation.

[0047] Specifically, a plurality of second fixing holes may also be provided on the web 211 , and the plurality of second fixing holes are arranged at intervals along the vertical direction.

[0048] For example, Figure 1 As shown, in the present embodiment, two positioning members 24 are provided; in other embodiments, a plurality of positioning members 24 may also be provided to further enhance the stability of the support member 21 fixed to the fixed frame 12 .

[0049] Furthermore, both ends of the positioning member 24 can extend out of the fixed frame 12 to ensure that the support member 21 can be fixed on the fixed frame 12. Specifically, an operating handle is provided at one end of the positioning member 24 to facilitate the operator to take the positioning member 24.

[0050] Optionally, a support slope is provided on the stopper 23, and the lattice shell structure abuts against the support slope. The above arrangement can increase the contact area between the stopper 23 and the lattice shell structure, and improve the support stability of the lattice shell structure. Specifically, the setting angle of the support slope can be set as needed, and is not specifically limited here.

[0051] Furthermore, the stopper 23 is made of a flexible material, such as a rubber material; or a flexible pad is provided on the support slope, and the flexible pad is in contact with the grid shell structure. Exemplarily, the flexible pad is a rubber pad. The above arrangement can not only ensure the stability of the grid shell structure support, but also absorb the vibration of the grid shell structure during the subsequent construction process and buffer the impact on the grid shell structure.

[0052] Optionally, a non-slip structure is provided on the side of the fixed base 1 facing the ground. Specifically, the non-slip structure is a non-slip pad, such as a rubber pad, provided on the side of the fixed base 1 facing the ground; or, the non-slip structure is a non-slip protrusion provided on the side of the fixed base 1 facing the ground, and the non-slip protrusion can be a dot-shaped protrusion or a pattern protrusion of any shape, and its function is to increase the contact friction between the fixed base 1 and the ground to prevent the fixed base 1 from moving. Its specific form refers to the prior art and is not specifically limited in this embodiment, as long as it can play a role in increasing friction.

[0053] Exemplarily, the operation process of the lattice shell structure support device described in this embodiment is as follows:

[0054] Move the support device to the bottom of the grid shell structure to be supported, so that the fixed plate 11 is supported on the ground, and the two driving mechanisms 3 are controlled to start synchronously through the control component, driving the support member 21 to rise relative to the fixed frame 12 in the vertical direction, so that the limit member 23 located on the top plate 22 abuts against the grid shell structure. When the required height is reached, the positioning member 24 is inserted into the corresponding first fixing hole and the second fixing hole, so that the fixed support member 21 is fixed on the fixed frame 12 to complete the support of the grid shell structure. At this time, the two driving mechanisms 3 can be controlled to close through the control component. When the construction of the grid shell structure is completed, the positioning member 24 is removed, and then the two driving mechanisms 3 are controlled to start synchronously through the control component to retract the support member 21 in the vertical direction.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
