Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1 and 6, the leveling assembly of the building machine of the present invention comprises a truss platform 1, a plurality of sets of jacking mechanisms 2, a leveling mechanism 3, a plurality of leveling instruments 4 and a controller 5.
Truss platform 1, as load-bearing platform, carries on automatic building construction equipment, can adopt prior art, generally adopts bailey frame to connect gradually and forms, and the frame construction who forms sets up around the wall body outside.
The jacking mechanism 2 drives the truss platform 1 to lift, and the prior art can be adopted. Specifically, as shown in fig. 2 and 3, the jacking mechanism 2 comprises three wall-attached seats 21, a guide rail 22, a lifting mechanism 23 and a lattice column 24.
Three wall attaching seats 21 are arranged on the wall body along the vertical direction and used for providing support for a guide rail 22 and a lifting mechanism 23.
The guide rail 22, which is elevated along the wall-attached base 21, can be made by the prior art. Specifically, the roller can be arranged on the wall attaching base 21, the guide rail 22 is in rolling connection with the roller, friction force is reduced, and meanwhile, the roller can limit the guide rail 22 and limit the guide rail 22 to lift only in the vertical direction.
The lattice columns 24, which are provided on top of the guide rails 22, support the truss platform 1, as is known in the art.
The lifting mechanism 23, which drives the guide rail 22 to lift along the wall attaching base 21, can be used in the prior art. The lifting mechanism 23 can be driven by a motor to rotate, and further drives the rack guide rail 22 to lift through a gear; hydraulic means may also be employed to drive the rail 22 up and down. Specifically, in the present embodiment, the lifting mechanism 23 is hydraulically driven, and includes a second hydraulic cylinder 25, two reversing boxes 26, and a C-shaped frame 27.
The second hydraulic cylinder 25 is extended or shortened to drive the rail 22 to move up and down along the wall attachment base 21 or to drive the second hydraulic cylinder 25 to move up and down along the rail 22, so that:
when the guide rail 22 needs to be driven to ascend and descend along the wall-attached base 21, the top end of the second hydraulic cylinder 25 needs to be connected with the guide rail 22, and the other end of the second hydraulic cylinder is fixed on the wall-attached base 21 through the C-shaped frame 27; when it is necessary to drive the second hydraulic cylinder 25 to move up and down along the guide rail 22, it is necessary that the top end of the second hydraulic cylinder 25 is connected to the guide rail 22 and the other end thereof lifts up and lifts the C-shaped frame 27.
Considering that the lifting stroke of the guide rail 22 along the wall-attached seat 21 is generally one floor height, and the stroke of the second hydraulic cylinder 25 is less than one floor height, the second hydraulic cylinder 25 needs to release the connection between the top end of the second hydraulic cylinder 25 and the guide rail 22 after lifting the guide rail 22 for one stroke, and repeats the operation of lifting the guide rail 22 for one stroke after retracting the second hydraulic cylinder 25, so that the guide rail 22 can be lifted for one floor height through a plurality of lifting strokes. In order to facilitate the connection and locking or unlocking of the top end of the second hydraulic cylinder 25 and the guide rail 22, two ends of the second hydraulic cylinder 25 of the present invention are respectively hinged with two reversing boxes 26, and the two reversing boxes 26 respectively ascend and descend along the guide rail 22 and are selectively fixed with the guide rail 22.
The C-shaped frame 27 is fixed with one of the reversing boxes 26 and selectively hung on the wall-attached base 21. Specifically, the C-shaped frame 27 is provided with a hook, the wall-attached seat 21 is provided with a hanging rod, and the C-shaped frame 27 can be hung on the hanging rod or freely separated from the hanging rod.
The lift cycle of the lift mechanism 23 is as follows:
taking the example of jacking the guide rail 22 by one floor height, the process is divided into a plurality of times:
s1, hanging a C-shaped frame 27 on a wall-attached base 21 to provide support;
s2, locking the top reversing box 26 with the guide rail 22, unlocking the bottom reversing box 26 with the guide rail 22, extending the second hydraulic cylinder 25 for one stroke, unlocking the guide rail 22 with the anti-falling device on the wall-attached base 21, and locking the guide rail 22 with the anti-falling device on the wall-attached base 21 again after jacking the guide rail 22 for one stroke;
s3, then, the top reversing box 26 is unlocked from the guide rail 22, the bottom reversing box 26 is locked with the guide rail 22, and the second hydraulic cylinder 25 retracts for one stroke;
and S4, repeatedly executing the steps S2 to S3, and thus jacking the guide rail 22 to a floor height.
Next, the second hydraulic cylinder 25 and the C-shaped frame 27 are lifted up by one floor height.
S5, unlocking the top reversing box 26 and the guide rail 22, locking the bottom reversing box 26 and the guide rail 22, and extending the second hydraulic cylinder 25 for one stroke;
s6, locking the top reversing box 26 with the guide rail 22, unlocking the bottom reversing box 26 with the guide rail 22, retracting the second hydraulic cylinder 25 for a stroke, jacking the C-shaped frame 27 for a stroke, and disengaging the hook on the low-rise wall-attached base 21 in the process;
s7, repeating the steps S5 to S6, so as to lift the C-shaped frame 27 to a floor height, and hanging the C-shaped frame 27 on a hanging rod on the high-floor wall-attached seat 21;
and S8, taking out the wall attaching base 21 of the lower floor, embedding the wall attaching base on the wall of the higher floor, and preparing for next jacking.
The lowering is substantially similar to the raising, and will not be described in detail herein.
Because the wall attaching bases 21 need to be pre-buried again every time the lifting cycle of one floor is completed, height checking exists during the pre-burying process of the height of each wall attaching base 21, and therefore the truss platform 1 cannot be kept horizontal and risks of high-altitude overturning exist.
