Embodiment 1

[0085] The step of setting the barb device 14 on the heavy structure 15, such as Figure 11 , 12 As shown in , the position of the barb device 14 is set, and a separate template is set. The template adopts the structure of a patchwork template, and a plurality of holes are arranged on the template, and a plurality of connecting bolts 25 pass through the holes and respectively connect with the embedded pad Plate nuts 23 are fixedly connected. In this example, each formwork is provided with at least 4 embedded backing plate nuts 23. This structure ensures that the distance between each embedded backing plate nuts 23 is a fixed value. Correspondingly, when loading and unloading The distance between each bearing pin 13 or bearing seat 12 on the frame 8 is also a fixed value corresponding to the distance between the connecting bolts 25 one by one. In order to be reliably connected with the loading and unloading rack 8 in succession. When erecting the mold, the template is set at ...

Embodiment 2

[0087] Carrying pin 13 is set on loading and unloading frame 8, adopts the mold of frame, and the double lug plate corresponding to bearing pin 13 positions is set on the mould, for example 4 double lugs, bearing seat 12 is passed through carrying pin 13 and double lug plate Connect to fix the relative position of the bearing seat 12, place the mold as a whole on the front end of the loading and unloading rack 8, the bearing base 12 is in contact with the loading and unloading rack 8, connect the bearing base 12 to the loading and unloading rack 8 by spot welding, and remove the bearing pin 13 , and then full welding connection between the bearing seat 12 and the loading and unloading frame 8, during the welding process, the deformation of the bearing seat 12 is controlled by staggered weld seams. In the above way, it is ensured that the bearing pin 13 and the barb device 14 are corresponding in position, and that the force between them is reliable, and the concentration of for...

Embodiment 3

[0089] The auxiliary positioning target 22 is set, and according to the parameters of the spatial distance between the position of the positioning sensor 16 and the installation position, the auxiliary positioning target 22 is offset by a corresponding spatial distance and set near the position to be installed. The traveling frame 1 is located at the hoisting station of the traveling track 2, such as Image 6 shown in . The lifting device lifts the heavy structure 15 , such as the closed door of the end of the underground sinking pipe, to the loading and unloading frame 8 , so that the barb device 14 is hooked on the bearing pin 13 . After being installed and fixed, the driving device 104 drives the traveling vehicle frame 1 to travel along the traveling track 2 to the installation station. According to the inclination angle of the installation position, the hydraulic oil output by the hydraulic station 20 controls the expansion and contraction of the piston rod of the inclin...

Abstract

The invention provides a method for loading and unloading heavy-duty structures, comprising the following steps: setting a walking track near the installation position, and the walking track at least passes through the installation station and the loading and unloading station; moving the loading and unloading trolley to the installation station, and moving the heavy-duty The structure is hoisted on the bearing seat of the heavy structure; the loading and unloading trolley is moved to the installation station, the loading and unloading trolley adjusts the space position of the heavy structure, and the installation of the heavy structure is assisted; the disassembly steps are opposite to the installation steps; through The above steps realize the precise loading and unloading of heavy structures by using the loading and unloading trolley. By adopting the structure of the loading and unloading trolley, and the loading and unloading trolley adopts a structure that can be fine-tuned up, down, front, back, left, and right, and pitch angles, the scheme of the cantilever structure is eliminated, and the spatial position of heavy structures can be precisely adjusted under the premise of ensuring reliable force. , to meet the needs of installation and disassembly of heavy structures, greatly reduce the occupation time of spreaders on the construction site, and improve construction efficiency.

Description

technical field [0001] The invention relates to the field of installation and disassembly of heavy structures, in particular to a method for loading and unloading heavy structures. Background technique [0002] The heavy-duty structures referred to in this example include structures that are difficult or inconvenient to carry by manpower, such as underground sinking pipes or steel end seal doors of corridors; prefabricated shear walls, prefabricated beams, prefabricated columns or other prefabricated structures Components; large integrated glass curtain wall units, etc. Taking the immersed tube steel end seal door as an example, the current installation mostly adopts the traditional construction method: first install the corbel and steel beam, and finally rely on the installed components to use the spreader and chain hoist to position and install the end seal door, which is also a lot of heavy-duty construction. The main installation method of the object. This construction...
