[0033] Reference Figures 1 to 6 A method for controlling the hoisting accuracy of a modular container house according to an embodiment of the present invention includes the following steps:

[0034] Step 1: Use a crane to lift the hoisting device above the container house 100. You can also use other lifting equipment such as a gantry crane to lift the hoisting device. The hoisting device includes a frame 200 and a hanger 300. The horizontal dimensions of the frame 200 are the same as the horizontal dimensions of the container house 100. The frame 200 is welded from I-beams, channel steels, and other steel sections. The frame 200 is rectangular, and the hanger 300 is vertically symmetrically connected to four hydraulic cylinders 330. The telescopic ends of the hydraulic cylinders 330 can extend downward. The lower end of the telescopic end of each hydraulic cylinder 330 is welded to a support leg 310, and the lower end of the support leg 310 can be against the ground. The hydraulic cylinder 330 can drive the support leg 310 to change its height to keep the hanger 300 level. The frame 200 is located below the hanger 300. The frame 200 is used to be detachably connected to the container room 100. The frame 200 and the hanger 300 are connected via a horizontal adjustment assembly 400. The lower end of the horizontal adjustment assembly 400 is movably connected to the center of the frame 200, and the upper end of the horizontal adjustment assembly 400 is movably connected to the center of the hanger 300. The horizontal adjustment assembly 400 includes a movable plate 410 and a drive device 420. The frame 200 is slidably connected to the movable plate 410, and the hanger 300 is slidably connected to the movable plate 410. The movement direction of the frame 200 relative to the movable plate 410 and the movement direction of the hanger 300 relative to the movable plate 410 are perpendicular to each other. The drive device 420 is used to drive the frame 200 to move forward and backward relative to the movable plate 410 and to drive the movable plate 410 to move left and right relative to the hanger 300. The drive device 420 can use servo electric cylinders, hydraulic cylinders and other parts that can achieve high-precision motion control;

[0035] Step 2: detachably connect the frame 200 to the container house 100;

[0036] Step 3: Use a crane to hoist the hoisting device and the container house 100 to the installation location;

[0037] Step 4: The crane releases the hook, and the four legs 310 are extended and pressed against the supporting surface by the hydraulic cylinder 330, thus raising the container house 100. The operator controls the hydraulic cylinder 330 to adjust the height of each leg 310 so that the bottom surface of the container house 100 remains level. It is foreseeable that a level bubble or electronic level or other equipment will be placed on the container house 100 to assist in determining whether the bottom surface of the container house 100 remains level.

[0038] Step 5: Control the leveling assembly 400 to move the container room 100 left and right, forward and backward, so that the container room 100 is aligned with the installation surface in the vertical direction;

[0039] Step 6: The operator controls the four hydraulic cylinders 330 to synchronously lower the height of the four legs 310, and horizontally move the container house 100 down to the installation surface;

[0040] Step 7: Bolt the container house 100 to the mounting surface and release the connection between the frame 200 and the container house 100.

[0041] The present invention provides a method for controlling the hoisting accuracy of a modular container house. A hoisting device and container house 100 are hoisted to the installation location by a crane. Once the crane has initially positioned the device, the device and container house 100 are lowered. Four legs 310 precisely adjust the elevation error and overall verticality error of the container top, while a horizontal adjustment assembly 400 precisely adjusts the offset error of the container centerline relative to the positioning axis. After lowering the device and container house 100, the crane can be moved to install the next container or perform other tasks. This improves crane utilization and, when cranes are limited, effectively increases the speed and accuracy of installing multiple container houses 100.

[0042] In some specific embodiments of the present invention, in step 2, four hydraulic hooks 210 are symmetrically connected to the four corners of the frame 200. The hydraulic hooks 210 include a hydraulic drive component 211 and a hook 212 hinged to the retractable end of the hydraulic drive component 211. The container room 100 is provided with a corner fitting box 110 for the hooks 212 to be inserted into. When the hydraulic drive component 211 drives the hooks 212 to extend, the hooks 212 are locked in the corner fitting box 110 of the container room 100. The hydraulic drive component 211 drives the hooks 212 to retract, securing the container room 100 to the frame 200. The hydraulic drive component 211 automatically secures the container room 100, reducing the operator's labor intensity.

[0043] In some specific embodiments of the present invention, in step one, before lifting, a hanging basket for the operator to ride in and an edge protection device to prevent the operator from falling are installed on the hanger 300. The specific structures of the hanging basket and the edge protection device are both existing technologies and are not shown in the figure and will not be described in detail. The operator is lifted together with the container room 100 and can judge the position of the container room 100 at close range, making the positioning of the container room 100 more accurate.

[0044] In some specific embodiments of the present invention, in step seven, bolting the container house 100 to the mounting surface is performed by an operator in a suspended basket. Because the mounting surface of the container house 100 may be high, tightening the bolts would be difficult for an operator standing on the ground. Therefore, the operator in the suspended basket bolts the container house 100 to the mounting surface. This eliminates the need for ground-based scaffolding, improving work efficiency.

[0045] In some specific embodiments of the present invention, in step seven, after the operator bolts the container house 100 to the installation surface, the hydraulic drive components 211 located at the four corners of the frame 200 drive the hooks 212 to extend, the operator takes the hooks 212 out of the corner box 110 and then controls the hydraulic drive components 211 to retract. At this time, the frame 200 is separated from the container house 100, and then the lifting device is lifted by a crane to the next container house 100 to be installed.

[0046] In some specific embodiments of the present invention, the lower end of the movable plate 410 is symmetrically provided with two lower slide grooves 411 extending forward and backward, and the upper end of the movable plate 410 is symmetrically welded with two upper slide rails 412 extending left and right. The upper end of the frame 200 is connected to a lower slide rail 220 that can be inserted into the lower slide groove 411, and the lower end of the hanger 300 is provided with an upper slide groove 320 for the upper slide rail 412 to be inserted into. The upper end of the upper slide rail 412 is cylindrical, and the upper end of the upper slide rail 412 is larger than the lower end of the upper slide rail 412. After the upper slide rail 412 is inserted into the upper slide groove 320, it can only move along the direction in which the upper slide groove 320 extends and cannot move up and down. The upper end of the lower slide rail 220 is cylindrical, and the upper end of the lower slide rail 220 is larger than the lower end of the lower slide rail 220. After the lower slide rail 220 is inserted into the lower slide groove 411, it can only move along the direction in which the lower slide groove 411 extends and cannot move up and down.

[0047] It is foreseeable that, for ease of processing, two bosses can be welded at the lower end of the movable plate 410, and the lower slide 411 is opened at the lower end of the boss; two bosses can be welded at the lower end of the hanger 300, and the upper slide 320 is opened at the lower end of the boss.

[0048] In some specific embodiments of the present invention, the driving device 420 includes an upper driving member 421 and a lower driving member 422. Due to the small installation space, the upper driving member 421 and the lower driving member 422 are hydraulically driven devices such as hydraulic cylinders, etc., and the use of hydraulic drive has higher accuracy. The specific structure of the hydraulic cylinder is prior art and will not be described in detail. The fixed end of the upper driving member 421 is bolted to the hanger 300, the telescopic end of the upper driving member 421 is bolted to the movable plate 410, the fixed end of the lower driving member 422 is bolted to the movable plate 410, and the telescopic end of the lower driving member 422 is bolted to the frame 200. The upper driving member 421 and the lower driving member 422 respectively control the left and right movement and the front and back movement of the frame 200. The structure is simple and the operation is reliable.

[0049] In some specific embodiments of the present invention, four positioning blocks 201 are provided at the bottom of the frame 200, located at the four corners of the rectangular frame 200. Four positioning slots 101 are provided at the top of the container house 100, each corresponding to one of the positioning blocks 201. When the container house 100 is secured beneath the frame 200, the positioning blocks 201 engage with the slots 101 to prevent horizontal displacement between the container house 100 and the frame 200, thus providing a more secure fit for the container house 100.

[0050] In some specific embodiments of the present invention, the hydraulic oil used by the hydraulic cylinder 330, the upper drive member 421, the lower drive member 422, and the hydraulic hook 210 can be provided by an oil pump mounted on the hanger 300, or by an oil pump on the ground via a hose or the like. The control methods for the hydraulic cylinder 330, the upper drive member 421, the lower drive member 422, and the hydraulic hook 210 are all conventional techniques and will not be described in detail.
