[0009] Preferably, the connecting beam is in a T-shaped structure, and the connecting beam includes a vertical portion and a horizontal portion. The horizontal portion of the connecting beam is arranged between the first enclosure wall and the second enclosure wall, and the horizontal portion of the connecting beam extends to the interior of the prefabricated cabin. When the lower cabin body and the upper cabin body are covered together, a sealing strip is provided at the joint between the first enclosure wall and the second enclosure wall to improve the sealing of the joint between the lower cabin body and the upper cabin body.

[0010] Preferably, a detachable guide wheel assembly is fixedly mounted on the back of the pile sleeve by bolts, and the guide wheel assembly plays an auxiliary supporting role when the lower cabin and the upper cabin are raised and lowered, and the guide wheel assembly can be removed after use.

[0022] A connecting mechanism is arranged at the rear side of the first enclosure wall 2, the second enclosure wall 3 is rotatably connected to the connecting mechanism, the front wall 4 covers the open window, and the first hydraulic telescopic rod 7 is rotatably installed on the inner walls on the left and right sides of the first enclosure wall 2. The first hydraulic telescopic rod 7 drives the connecting mechanism to flip, driving the upper cabin to flip and open and close. When the lower cabin and the upper cabin are covered together, a sealing strip 16 is arranged at the joint between the first enclosure wall 2 and the second enclosure wall 3 (see Figure 1 or Figure 2 ).

[0023] Specifically, the connecting mechanism includes a telescopic pile 8 and a connecting beam 9. The telescopic pile 8 is fixedly installed on the surface of the first enclosure wall 2. The connecting beam 9 is rotatably connected to the telescopic end of the telescopic pile 8. The second enclosure wall 3 is rotatably connected to the upper surface of the connecting beam 9. The telescopic end of the first hydraulic telescopic rod 7 is rotatably connected to the connecting beam 9. The left and right inner walls of the second enclosure wall 3 are rotatably installed with a second hydraulic telescopic rod 10. The telescopic end of the second hydraulic telescopic rod 10 is rotatably connected to the connecting beam 9.

[0024] Among them, the telescopic pile 8 includes a pile sleeve 11 and a telescopic plate 12, the telescopic plate 12 is slidably installed in the pile sleeve 11, the pile sleeve 11 is fixedly connected to the surface of the first enclosure wall 2, the connecting beam 9 is rotatably connected to the top of the telescopic plate 12, and a plurality of limiting holes 13 are opened on the surface of the telescopic plate 12. The inner wall of the first enclosure wall 2 is threadedly installed with a locking bolt 14, and the end of the locking bolt 14 extends into the pile sleeve 11 and can be inserted into the limiting hole 13.

[0025] In this embodiment, Figure 8 As shown, a third hydraulic telescopic rod 15 is fixedly installed inside the pile sleeve 11, and the telescopic end of the third hydraulic telescopic rod 15 is fixedly connected to the telescopic plate 12. When the locking bolt 14 is unscrewed, the third hydraulic telescopic rod 15 telescopes and drives the telescopic plate 12 to move upward or retract downward.

The horizontal portion of the connecting beam 9 is arranged between the first enclosure wall 2 and the second enclosure wall 3, and the horizontal portion of the connecting beam 9 extends to the interior of the prefabricated cabin. Figure 6 As shown, the second enclosure wall 3 and the first enclosure wall 2 are rotatably connected to the upper and lower sides of the vertical part of the connecting beam 9 respectively, and the telescopic ends of the second hydraulic telescopic rod 10 and the first hydraulic telescopic rod 7 are rotatably connected to the upper and lower side surfaces of the horizontal part of the connecting beam 9 respectively.

[0027] In this embodiment, a detachable guide wheel assembly 17 is fixedly installed on the back of the pile sleeve 11 by bolts. When the lower cabin and the upper cabin are raised and lowered, the guide wheel assembly 17 has an auxiliary support function. After use, the guide wheel assembly 17 can be removed.

[0028] The prefabricated cabin proposed in the present invention has the function of automatic loading and unloading to a transport vehicle, thereby achieving the effect of convenient transportation. In particular, the prefabricated cabin is large in size, and generally a large crane needs to be rented for loading and unloading. The lifting operation is cumbersome and has a high risk of rollover.

[0029] Specifically, when the prefabricated cabin is loaded onto a truck, Figure 6 As shown, the flatbed transport vehicle drives to the side of the prefabricated cabin, the third hydraulic telescopic rod 15 extends, lifts the connecting beam 9, raises the height of the upper cabin, and the first hydraulic telescopic rod 7 extends to drive the upper cabin to flip (as shown in FIG. Figure 3 In the above state, the second hydraulic telescopic rod 10 extends to drive the upper cabin to flip (as shown in FIG. Figure 4 The third hydraulic telescopic rod 15 is then retracted to place the upper cabin body on the flatbed transport vehicle with the cabin top plate 5 facing downwards, and the upper cabin body is fixed to the flatbed transport vehicle by bolts, and the third hydraulic telescopic rod 15 is retracted to separate the base 1 of the lower cabin body from the ground, and the first hydraulic telescopic rod 7 and the second hydraulic telescopic rod 10 are retracted to drive the lower cabin body to flip over and cover the upper side of the inverted upper cabin body; It should be noted that when the third hydraulic telescopic rod 15 is extended and the telescopic plate 12 is pushed upward, Figure 7 As shown, the angle of the connecting beam 9 can be controlled by extending and retracting the first hydraulic telescopic rod 7, or the angle of the upper cabin body relative to the lower cabin body can be controlled by extending and retracting the second hydraulic telescopic rod 10 to avoid interference between the upper cabin body and the lower cabin body; during the extension and retraction process of the telescopic pile 8, the first hydraulic telescopic rod 7 or the second hydraulic telescopic rod 10 also needs to properly adjust the extension length to ensure that the upper cabin body or the lower cabin body is level, the same below.

[0030] When the prefabricated cabin is unloaded, Figure 5 As shown, the lower cabin body is driven to flip over by extending the first hydraulic telescopic rod 7 and the second hydraulic telescopic rod 10, and then the third hydraulic telescopic rod 15 is extended to make the lower cabin body fall to the ground, and the base 1 is fixed to the ground by anchor bolts, and then the third hydraulic telescopic rod 15 is extended again to separate the upper cabin body from the flatbed transport vehicle, and the upper cabin body is driven to flip over and cover the upper side of the lower cabin body by contracting the first hydraulic telescopic rod 7 and the second hydraulic telescopic rod 10.

[0031] When installing the internal equipment, the first hydraulic telescopic rod 7 is extended to drive the upper cabin to flip (such as Figure 3 The upper cabin body is in the above-mentioned state, so that the front side of the lower cabin body becomes an open window, and the equipment can be transported into the cabin by a forklift to install the internal equipment. After the installation is completed, the first hydraulic telescopic rod 7 is retracted to drive the upper cabin body to flip downward and cover the upper side of the lower cabin body, and then the upper cabin body and the lower cabin body are fixedly connected by bolts (this is a conventional connection method, not shown in the drawings, and will not be described here).

[0032] The prefabricated cabin proposed by the present invention, the upper cabin body and the lower cabin body are assembled together through a connecting mechanism, which meets the need of turning over the upper cabin body and the lower cabin body. Since the telescopic pile 8 of the connecting mechanism has the function of lifting and controlling the lowering speed, it has the following advantages: (1) When the prefabricated cabin is loaded onto a truck, the height of the upper cabin body is raised by the telescopic piles 8, so that the upper cabin body can be turned over and placed on the transport vehicle; (2) When the equipment in the prefabricated cabin is installed and the upper cabin needs to be covered, the height of the upper cabin is raised by telescopic piles 8, and then the upper cabin is turned over and covered, so as to avoid interference between the turned upper cabin and the internal equipment due to the equipment in the cabin being too high; (3) When the prefabricated cabin is unloaded, the lower cabin body is slowly lowered horizontally by contracting the telescopic pile 8 and extending the first hydraulic telescopic rod 7, so that the base 1 can be accurately aligned with the anchor bolts on the ground, achieving the effect of convenient installation and fixing; It should be noted that in order to ensure that the anchor bolts are accurately inserted into the bolt holes of the U-profile 18, it is necessary to park the flatbed transport truck at a suitable position in the early stage, use a jack to push the prefabricated cabin on the flatbed transport truck, and fine-tune the position of the prefabricated cabin until the distance between the prefabricated cabin and the anchor bolts meets the requirements after measurement.

[0033] (4) When the height of the upper cabin is controlled by the telescopic pile 8, the size of the joint gap between the upper cabin and the lower cabin can be adjusted, which facilitates the installation of the sealing strip 16.

[0034] The prefabricated cabin proposed in the present invention consists of an upper cabin body and a lower cabin body, and a hydraulic actuator (i.e., a first hydraulic telescopic rod 7, a second hydraulic telescopic rod 10, and a third hydraulic telescopic rod 15) is arranged inside the cabin body. The upper cabin body is flipped open by hydraulic drive, so that the front side of the lower cabin body becomes an open window, which provides convenience for forking equipment into the cabin body, solves the problem that the existing prefabricated cabin has a small door opening and a narrow internal space, which makes it inconvenient to move equipment from the outside into the cabin for assembly. The prefabricated cabin is equipped with a hydraulic actuator and does not need to be equipped with a hydraulic power system (i.e., a hydraulic pump and a hydraulic oil tank), so that the structure is simple and the dead weight is reduced. When using the above-mentioned hydraulic actuator, an external hydraulic power system can be carried to provide hydraulic power for the hydraulic actuator structure. This design also provides convenience for the later installation of equipment in the prefabricated cabin and maintenance and replacement.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
