Description

Mechanical hydraulic device for automatically lifting and assembling and disassembling standard section of tower

Technical Field

The utility model belongs to the technical field of building construction, and relates to a mechanical hydraulic device for automatically lifting and assembling and disassembling a standard section of a tower.

Background

With the rise of intelligent construction disciplines and industry fields, a construction mode replaced by a robot becomes a hot spot for intelligent construction direction research. In the traditional building industry, the construction mode mainly comprising scaffolds has the defects of low efficiency and high consumption; the existing technical scheme of a building machine realizes automation of construction, but the building machine can only operate by relying on a building with a certain height, so the building machine is not suitable for automatic unmanned construction of a low large-plane building. If a building system which takes the ground as a support and has the function of automatic lifting can be provided, the gap of the building system can be filled.

For automatic lifting, a technical scheme similar to a standard section of a tower crane can be adopted, and lifting of a building system is realized through the process of lifting, connecting, dismounting and descending of the standard section.

CN103738891B proposes a standard section jacking device and a construction method for continuously and automatically jacking a standard section, which realizes that a small-stroke jacking jack can jack a higher standard section, and the standard section jacks up from the bottom. In the device, however, the connection of the two standard sections still adopts the bolt connection, manual intervention is needed, full-automatic implementation of the jacking process can not be realized, and the efficiency is lower. Meanwhile, in the force system conversion process of the device, the gravity of the standard joint is born by the lug plate on the standard joint, and the shearing damage of the lug plate can be caused, so that the device is invalid.

CN114963586a proposes a standard knot convenient for assembly, which realizes the quick connection and disassembly of the standard knot, the device drives the rotary motion of the grabbing rod through the abutting action of the inserting rod, and then grabs or releases the snap ring, wherein the snap ring is a fixed component. When the standard joint is in a connection state, the device realizes axial locking of the standard joint under the action of the return spring, but the device is not effectively connected and locked in the radial direction, and radial movement can be generated in the use process so as to influence the structural stability.

CN114263665a proposes a standard joint connection structure, which realizes the quick connection between standard joints, and the device is inserted into the slot through a rack and pinion driving reinforcing rod, realizes guiding and positioning, and is connected by a fastener on the U-shaped plate. But the fixed connection still adopts the bolted connection, needs the human intervention, and degree of automation is not high.
