[0022] It should be noted that the pipe truss structure unloading device 1 provided in this embodiment can be used both as a temporary support device during the truss installation process and as an unloading device after the truss installation is completed. It enables the deformation amount of the truss to be controllable during the truss unloading process and reduces the potential safety hazards that are likely to occur during the truss unloading process.

[0023] The usage process of the pipe truss structure unloading device 1 provided in this embodiment is as follows: S1. According to the design form of the truss, select a suitable jack 10 and connection unit 20 through calculation. Sleeve the connection unit 20 on the jack 10 to form a complete pipe truss structure unloading device 1, and install the bottom end of the pipe truss structure unloading device 1 on the truss temporary support platform; S2. According to the requirements of the truss installation plan, adjust the jack 10 so that the piston of the jack 10 moves upward. The piston pushes the connection unit 20 upward until the height of the pipe truss structure unloading device 1 meets the requirements of the installation plan, and the piston stops moving. Then install the truss. At this time, the truss is located at the top of the connection unit 20, and the pipe truss structure unloading device 1 plays a temporary support role for the truss; S3. After the truss is installed, welded and inspected to be qualified, operate the jack 10 so that the piston of the jack 10 moves downward. The piston drives the connection unit 20 downward. When the descending height of the top end of the connection unit 20 reaches the maximum height of the truss unloading deformation, the top end of the connection unit 20 no longer contacts the truss, and the unloading is successful. The pipe truss structure unloading device 1 can be removed; S4. If when the descending height of the top end of the connection unit 20 reaches the maximum height of the truss unloading deformation, the top end of the connection unit 20 still contacts the truss and shows no sign of detachment, immediately operate the jack 10 to lift the truss to the height before unloading, analyze and find out the reason, and repeat the operation of S3 again after the problem is solved.
