In other embodiments of the invention: the number of the precast slab link mechanisms can be set according to the requirement, for example, three, five or other numbers; the upper side telescopic rod, the lower side telescopic rod and the auxiliary telescopic rod can also be electric push rods; the rotation fit between the device upright post and the device base can be realized in a shaft hole mode, for example, a rotating shaft is fixed at the bottom of the device upright post, and a rotating shaft assembling hole which is in rotation fit with the rotating shaft is formed in the device base; the prefabricated plate lifting mechanism can also be in other forms, for example, a rack is directly arranged on the device upright post, the prefabricated plate lifting seat is matched with the device upright post in a guiding and moving manner in the up-down direction, a lifting seat driving motor is arranged on the prefabricated plate lifting seat, and a gear meshed with the rack for transmission is in transmission connection on a motor shaft of the lifting seat driving motor, so that when the lifting seat driving motor works, the prefabricated plate lifting seat is driven to lift by meshing of the gear and the rack.
The upper ring beam mounting groove on the upper ring beam can be omitted, and at the moment, all the upper ring beam connecting holes are positioned on the lower side of the upper connecting holes of the precast slab as shown in figure 12; the lower ring beam mounting groove on the lower ring beam is not needed, and all the lower ring beam connecting holes 35 are positioned at the lower side of the connecting holes at the lower side of the precast slab as shown in fig. 10.
The construction method of the assembling type cabin top plate of the squat circular cabin is shown in figures 1-14:
in the first step, the connection between the first batch of fan-shaped prefabricated plates and the prefabricated plate link mechanisms of the corresponding rotary jacking devices is completed, the number of the first batch of fan-shaped prefabricated plates corresponds to the number of the prefabricated plate link mechanisms, and the specific structure of the rotary jacking devices is the same as that of the above-mentioned rotary jacking devices, and therefore, detailed description is omitted.
Specifically, firstly, a first fan-shaped prefabricated slab of a first batch of fan-shaped prefabricated slabs is transported to the inner side of a bin wall through a bin door, the first fan-shaped prefabricated slab is detachably connected with an upper side telescopic rod and a lower side telescopic rod of a prefabricated slab connecting rod mechanism through a hinge structure, then, a device upright post is rotated, the first fan-shaped prefabricated slab is rotated away from the bin door, the second fan-shaped prefabricated slab is connected with a corresponding prefabricated slab connecting rod mechanism, and the steps are repeated to complete the connection of all the first batch of fan-shaped prefabricated slabs and the prefabricated slab connecting rod mechanism;
secondly, the prefabricated plate lifting mechanism drives the prefabricated plate lifting seat to drive the fan-shaped prefabricated plate to move upwards, after the upper ring beam connecting end of the fan-shaped prefabricated plate crosses the upper ring beam, the prefabricated plate connecting rod mechanism adjusts the position and the pitching angle of the fan-shaped prefabricated plate, the upper ring beam is rotated, the fan-shaped prefabricated plate is connected with the upper ring beam, the device upright post is rotated, and the fan-shaped prefabricated plate is connected with the lower ring beam;
thirdly, removing the connection between the fan-shaped prefabricated plates and the prefabricated plate connecting rod mechanisms, enabling the prefabricated plate connecting rod mechanisms to descend, repeating the first step to finish the connection between a second batch of fan-shaped prefabricated plates and the corresponding prefabricated plate connecting rod mechanisms respectively, and repeating the second step to finish the connection between the second batch of fan-shaped prefabricated plates and the upper ring beam and the lower ring beam;
and fourthly, repeating the third step to finish the connection of the last batch of fan-shaped precast slabs with the upper ring beam and the lower ring beam.
And in the second step, before the prefabricated plate lifting mechanism drives the prefabricated plate lifting seat to drive the fan-shaped prefabricated plate to move upwards, the prefabricated plate connecting rod mechanism adjusts the position and the pitch angle of the fan-shaped prefabricated plate so that the fan-shaped prefabricated plate is in a retracted state, the retracted state refers to a state that the upper end and the lower end of the fan-shaped prefabricated plate are both close to the device upright post, after the upper ring beam connecting end of the fan-shaped prefabricated plate crosses the upper ring beam, the prefabricated plate connecting rod mechanism adjusts the position and the pitch angle of the fan-shaped prefabricated plate, the fan-shaped prefabricated plate is in an unfolded state, and the unfolded state refers to a use state when the fan-shaped prefabricated plate forms the bin top. In other embodiments of the present invention, each of the fan-shaped precast slabs may also be directly lifted upward in the unfolded state as long as the upper and lower ring beams do not interfere with the movement of the fan-shaped precast slabs.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
