Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, and in particular to an auxiliary installation device for fabricated building construction. BACKGROUND

[0002] Compared with traditional reinforced concrete buildings, fabricated buildings have the characteristics of fast construction speed, small environmental pollution, and low cost. In recent years, with the continuous progress of fabricated building construction technology and building materials, fabricated buildings have been widely promoted and well developed. The core is to transfer a large number of on-site operations in traditional construction methods to factories, prefabricate building components and accessories (such as floors, walls, stairs, balconies, etc.) in factories, and then transport them to the construction site. Through reliable connection methods, it is assembled and formed on site. In the construction process of fabricated buildings, the installation of prefabricated hollow columns is one of the key links. First, the crane lifts the hollow column and moves it to the designated position of the construction operation surface; then, the construction personnel adjust the hollow column to the appropriate angle to ensure accurate positioning; finally, after the installation is completed, the connection device between the crane and the hollow column is released, and the entire lifting process is completed.

[0003] The existing Chinese invention patent with the publication number CN116971627B proposes to use a movable trolley that can fix the hollow column for installation. This method helps to reduce the occupancy rate of the crane and can adjust the inclination of the hollow column according to the unevenness of the bottom surface to ensure accurate docking of the connecting steel and the connecting sleeve. However, this patent has obvious limitations: it can only adjust the inclination of the hollow column in a single direction, and during the adjustment process, because of the unevenness of the bottom surface, the trolley is already in an inclined state, and the center of gravity is not stable. It is prone to rollover under mechanical vibration or worker operation interference, causing safety hazards.

[0004] Therefore, in view of the above technical problems, it is necessary to design a hollow column inclination angle adjustment structure that can adjust the device's center of gravity while adjusting the column's posture, keeping the whole body stable and effectively preventing rollover. This structure should rely on mechanical transmission to achieve synchronous center of gravity compensation, with the characteristics of simple operation, rapid response, and strong applicability, thereby ensuring construction safety and installation accuracy. SUMMARY

[0005] In order to overcome the problem that the center of gravity of the hollow column deviates during the adjustment of the inclination angle, the base itself is inclined and the counterweight is not adjusted synchronously, which can easily cause rollover due to mechanical vibration or improper operation, and poses a safety hazard.

The transmission assembly includes a first synchronous wheel 2101 and a second synchronous wheel 2102 movably connected to the base, a synchronous belt 2103 transmissionally connected between the first synchronous wheel 2101 and the second synchronous wheel 2102, and a transmission swing arm 2105 movably connected at one end to an eccentric position of the second synchronous wheel 2102, the first synchronous wheel 2101 is fixedly installed on the first linkage bevel gear 1603, one end of the turbine 22 is provided with a transmission disc 2104, the other end of the transmission swing arm 2105 is movably connected to an eccentric position of the transmission disc 2104, the first synchronous wheel 2101 drives the second synchronous wheel 2102 to rotate through the synchronous belt 2103, the second synchronous wheel 2102 drives the transmission disc 2104 and the turbine 22 to rotate through the transmission swing arm 2105, when the base moves away from the embedded part 23 through the rear walking wheel 2 and the front walking wheel 3, the turbine 22 rotates and accelerates the water to flow from the water storage bin 19 to the spray head 20.

[0043] Work flow: First, use the tower crane or crane to vertically hoist the prefabricated hollow column 24 into the positioning frame 801 (the cross-sectional size of the positioning frame matches the cross-sectional size of the hollow column), so that the lower end edge of the hollow column 24 accurately falls on the bracket 802, and the bracket 802 supports the hollow column 24; second, through the operation window on the back plate 601 and the surrounding plate 701, twist the screw knob to push the first side pressing plate 803 to extrude the surface of the hollow column 24 and strengthen the lateral locking force; third, install the cross beam 804 on the positioning frame 801 using fasteners (bolts and nuts) (note that the length of the cross beam 804 should not exceed the width of the wall plate); finally, adjust the screw knob on the second side pressing plate 805 to extrude the second side pressing plate 805 on the surface of the hollow column 24. At this point, the hollow column 24 is fastened and supported on the bracket 802 by the first side pressing plate 803 and the second side pressing plate 805;

[0044] The base gradually approaches the embedded part 23 on the ground through the rolling of the rear walking wheel 2 and the front walking wheel 3 (it is worth noting that the rear walking wheel 2 and the front walking wheel 3 both have self-locking devices, which are locked when stopping to prevent accidental movement), until the embedded part 23 enters the alignment area 102, and the hollow column 24 is above the embedded part 23. By slightly adjusting the position of the base, the connecting steel bars at the bottom of the hollow column 24 are corresponded to the connecting sleeves on the embedded part 23 one by one (roughly corresponded, because the surface of the floor is not flat during pouring or installation, causing the base to be in an inclined state, so the hollow column 24 may be in a relative inclined state relative to the embedded part 23, and it is difficult for the connecting steel bars and the connecting sleeves to be fully connected). During the approach of the device to the embedded part 23, the rear walking wheel 2 drives the linkage worm gear 1601 to rotate, which in turn drives the linkage worm gear 1602 and the first linkage bevel gear 1603 to rotate, and the first linkage bevel gear 1603 drives the second linkage bevel gear 1604 to rotate (it is worth noting that the transmission ratio of the first linkage bevel gear 1603 and the second linkage bevel gear 1604 is less than 1, that is, speed increasing transmission), which drives the fan blades to rotate at high speed in the fan cover, and drives the air flow to be discharged through the nozzle 18. At this time, the operator can hold the nozzle 18 to blow the connection position of the embedded part 23 and the hollow column 24 with air flow to remove the dust on the surface of the connecting steel bars. During the movement of the equipment, the nozzle can also be used to blow away the concrete debris and blocks on the floor surface to enhance the overall stability of the device during movement and reduce the risk of excessive inclination of the base caused by the accumulation of debris;

[0045] When the hollow column 24 and the embedded part 23 are inclined, the operator can choose to start the first motor 901 or the second motor 1001 in sequence or simultaneously according to the actual inclination direction; as shown in the accompanying Figure 1 When the hollow column 24 and the embedded part 23 are inclined in the H1 direction, the first motor 901 is started to drive the first main gear 902 to rotate, and the engagement of the first main gear 902 and the first slave gear 903 drives the surrounding plate 701 and the hollow column 24 locked in the positioning frame 801 to rotate in the H1 direction for corresponding adjustment, until the bottom surface of the hollow column 24 and the top surface of the embedded part 23 are parallel (the embedded part 23 is calibrated by a level during installation, so its plane is in a horizontal state, and therefore the hollow column 24 is also in a horizontal state after correction); as shown in the accompanying Figure 1As shown, when the hollow column 24 and the embedded part 23 are inclined in the H2 direction, the second motor 1001 drives the second worm gear 1002 to rotate, and then the second worm gear 1002 is engaged with the second worm 1003 to drive the transmission structure of the second main sprocket 1004, the second secondary sprocket 1005, the second slave sprocket 1006 and the chain belt 1007, so as to drive the positioning frame 801 and the hollow column 24 locked in the positioning frame 801 to rotate in the H2 direction until the bottom surface of the hollow column 24 is parallel to the top surface of the embedded part 23, so as to realize horizontal correction.

[0046] In the starting process of the first motor 901 or the second motor 1001, the torque sensor 1502 in the corresponding sensing unit monitors the torque value of the corresponding torsional spring 1501 in real time (the torque value reflects the rotation angle of the surrounding plate 701 in the H1 direction and the rotation angle of the positioning frame 801 in the H2 direction), respectively sends signals to the lateral electric valve 1105 and the forward electric valve 1306, and opens the corresponding lateral guide pipe 1104 and the forward guide pipe 1305. In the process of rotating the surrounding plate 701, the lateral plunger 1102 moves in the lateral water cavity 1101 under the swing action of the lateral rocker arm 1103, and then drives the water in the lateral water cavity 1101, the first lateral counterweight bin 1201 and the second lateral counterweight bin 1202 to flow alternately (when the base is inclined in the H1 direction, the water in the lateral water cavity 1101 flows to the side with higher elevation in the lateral counterweight group, and the water on the other side is pumped into the lateral water cavity 1101, so that the weight of the base on the side with higher elevation is heavy, and the weight on the side with lower elevation is light, which effectively enhances the stability of the base in the H1 direction during the installation of the hollow column 24, and reduces the risk of overturning); in the process of rotating the positioning frame 801, the forward plunger 1302 moves in the forward water cavity 1301 under the swing action of the forward rocker arm 1304, and then drives the water in the forward water cavity 1301, the first forward counterweight bin 1401 and the second forward counterweight bin 1402 to flow alternately (when the base is inclined in the H2 direction, the water in the forward water cavity 1301 flows to the side with higher elevation in the forward counterweight group, and the water on the other side is pumped into the forward water cavity 1301, so that the weight of the base on the side with higher elevation is heavy, and the weight on the side with lower elevation is light, which significantly improves the anti-overturning ability of the base in the H2 direction and ensures the overall stability of the hollow column installation operation.).

[0047] With the hollow column 24 tilt angle adjustment in place, start the main motor 501, through the lead screw 502 drive with the carriage 602 back plate 601 down to move, make the connection reinforcement and the connection sleeve close. The operator then rotates the sleeve for connection, after the completion of the connection, the beam 804 from the positioning frame 801 removed, and remove the rear walking wheel 2 and front walking wheel 3 of the locking state, make the device move away from the embedded part 23. In the process of rear walking wheel 2 rotation, the first synchronous wheel 2101 follow-up linkage worm gear 1602 rotation, through the second synchronous wheel 2102 and synchronous belt 2103 will power transmission to the transmission swing arm 2105, make the transmission disc 2104 and turbine high speed rotation, in the water storage warehouse 19 form high pressure, the water storage warehouse 19 in the water from the nozzle 20 to the bottom of the hollow column 24 and embedded part 23 (it is worth noting that here is the device away from the embedded part 23, the rotation direction of the turbine is positive, in the water storage warehouse 19 form positive pressure; If the forward movement, then reverse rotation, no water pressure), the wet processing helps to improve the subsequent pouring of concrete and hollow column 24 and embedded part 23 of the combination quality.
