Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of prefabricated component transportation, and particularly relates to a stable prefabricated component transfer device for house building. BACKGROUND

[0002] Fabricated building refers to the fact that a large number of on-site operations in the traditional construction mode are transferred to a factory, and building components and accessories are processed and manufactured in the factory. These components are referred to as prefabricated components, which are transported and stored on the construction site using a transfer device, and then assembled and installed on site through reliable connection methods.

[0003] With the continuous development of fabricated technology, prefabricated components are gradually combined with building insulation, fireproofing, exterior wall decoration, doors and windows to form integrated prefabricated components for convenient use. The front and rear sides of the integrated prefabricated components are prefabricated with a thermal insulation layer and a decorative surface of the wall, and in order to connect with the building frame during construction, steel bars are pre-buried on the left and right sides or on the top of the prefabricated components. The current common methods for transporting prefabricated components include leaning and standing. Based on the characteristics of integrated prefabricated components, they cannot be directly stacked and leaned during transportation, which requires the use of a dedicated transfer device to transport and temporarily store on the construction site by standing and inserting. The existing transfer device mostly uses a fixing device to fix the front and rear of the prefabricated component to stand and insert the prefabricated component. This method causes damage to the surface of the prefabricated component during transportation. Since the installation position of the prefabricated component is different, the shape and thickness of the prefabricated component are also different. The existing transfer device mostly can only transport and store one type of prefabricated component, resulting in an increase in the transportation cost of prefabricated components.

[0004] Therefore, it is necessary to study a stable prefabricated component transfer device for house building that can stably transport and store prefabricated components without causing damage to the prefabricated components. SUMMARY

[0044] The first fixing device 3 is fixedly installed on the first sliding block 15 and the third sliding block 17, and specifically, the first fixing device 3 comprises a connecting plate 31, a first hydraulic rod 32, a hydraulic oil passage block 33, a second hydraulic rod 34, a spring 35 and a contact part 36. The connecting plate 31 is fixedly connected to the first sliding block 15 and the third sliding block 17. The hydraulic oil passage block 33 is installed on the connecting plate 31 through the first hydraulic rod 32. One end of the second hydraulic rod 34 is fixedly installed on the hydraulic oil passage block 33, and the other end is connected to the contact part 36. Specifically, the side on which the second hydraulic rod 34 is installed on the hydraulic oil passage block 33 is provided with an inclined surface inclined to both sides.

[0046] The working principle of the present application is as follows:

[0047] Please refer to Figures 7 to 9 As shown in the figure, the prefabricated component is fixed by hoisting the prefabricated component vertically and inserting it into the driving bracket 1 through the hoisting device, the height of the first fixing device 3 on the hoisting support arm 11 is adjusted through the first driving mechanism, then the first hydraulic rod 32 is controlled to be elongated through the hydraulic station 19, after the contact part 36 on the first fixing device 3 cooperates with the side surface of the prefabricated component, the first hydraulic rod 32 and the second hydraulic rod 34 are locked through the hydraulic station 19, so that the lower end of the prefabricated component can be fixed, then the height of the second fixing device 4 is adjusted through the second driving mechanism, the rotary table 41 and the U-shaped connecting piece 43 are adjusted according to the position of the connecting piece pre-buried on the prefabricated component to make the connecting rod 44 contact with the connecting piece, and the two are fixedly connected through welding, so that the fixing of the upper end of the prefabricated component is completed, and at this time the prefabricated component is stably fixed on the transfer device.

[0048] The interval between the two adjacent transfer stations is adjusted, so that prefabricated components with different thicknesses or shapes can be fixed, the two adjacent transfer devices can be connected with each other through the connecting female head 212 and the connecting male head 231, and the interval between the two adjacent transfer devices and the prefabricated components can be controlled by controlling the third hydraulic rod 23 to be elongated or shortened through the hydraulic station 19, so that the transfer device can fix the prefabricated components which are wider or have corners by expanding the interval, and the interval between the two prefabricated components can be increased before the hoisting equipment hoists the prefabricated components, so as to facilitate hoisting.
