[0001] The invention relates to the technical field of construction, in particular to an expandable container module house and a construction method thereof. Background Art

[0002] With the development of society, the demand for flexible expansion of temporary building space is increasing. Traditional container modular houses have shortcomings in terms of mobility and support.

[0003] When traditional container modular houses need to be supported or moved, they are often hoisted by large equipment such as cranes. This method is not only complicated to operate, but also has high requirements for site and equipment. At some construction sites, it is very difficult to move container modular houses due to narrow sites or lack of suitable hoisting equipment.

[0004] In the current design of container modular houses, the mobile function and the support function are often independent of each other and are not well combined. This results in the need for complex operations and additional equipment to switch from the mobile state to the support state or vice versa in actual use.

[0013] An expandable container modular house and a construction method thereof, comprising the following steps:

[0014] S1. Produce the overall structural components in the factory to ensure that the size and quality meet the requirements, manufacture the transmission components, install the motor 1 and motor 2 to the corresponding positions, connect the corresponding transmission components to ensure accurate meshing, prefabricate the sliding connection components and install them to the corresponding positions, assemble the rotating components of the legs to ensure their reliability;

[0015] S2. Pack the prefabricated components and pre-install the modules of some transmission mechanisms, transport them to the construction site, pay attention to protecting the precision components, level the site and do foundation treatment on site, and prepare auxiliary equipment;

[0016] S3. Place the box on the foundation, start motor 2, adjust the position of the universal wheel and the support through the transmission mechanism to make the box initially stable, start motor 1, and drive the expansion box 1 and the expansion box 2 to expand outward through the transmission mechanism to achieve space expansion. Check the leg rotation assembly during the expansion process, and conduct a comprehensive debugging and inspection after assembly to ensure that all functions are normal.

[0017] Working principle: When the state needs to be changed, start the motor 2 in the shell, and the bevel gear 4 at its output end rotates, driving the bevel gear 3 meshing with it to rotate synchronously, and then rotating shaft 2 rotates. The worm 2 on both sides of the middle of rotating shaft 2 drives the worm wheel 2 to rotate, driving the screw 2 to move axially, so that the base and the universal wheel can be raised and lowered; at the same time, the worm 1 at both ends of rotating shaft 2 drives the worm wheel 1 to rotate, driving the screw 1 to raise and lower the pillar, and the opposite threads of screw 1 and screw 2 are used to achieve rapid switching between movement and support. When the top space is expanded, turn on the motor 1 in the shell, and the bevel gear 1 drives the bevel gear 2 to rotate, driving the expansion component that runs through the bottom of the box. The gear rotates, and by meshing with rack 1 and rack 2, it pushes rack 2 to drive the expansion box 1 to expand outward along the slide bar 1 and the slide groove 1, and at the same time, rack 1 drives the expansion box 2 to expand synchronously along the slide bar 2 and the slide groove 2. The rotating assembly of the side wall leg rotates around the rotating axis when dealing with different working conditions, and the ratchet moves accordingly. The pawl clamps the ratchet under the elastic force of the spring to ensure the stability of the leg. The angle can be flexibly adjusted as needed to ensure that the container can adapt to various scenarios.

[0018] The present invention provides an expandable container modular house and a construction method thereof, which has the following beneficial effects:

[0019] 1. The present invention cleverly sets a transmission system driven by motor 2 in the shell at the bottom of the box body, which includes a bevel gear, a rotating shaft, a worm, a worm wheel and a lead screw. When moving, the universal wheel can be quickly and accurately lowered, the support can be raised, the lifting equipment can be freed, and the height can be adjusted according to the ground to ensure smooth movement. After being in place, the support can accurately support and adapt to site conditions, thus solving the problem of inconvenient conversion between support and movement.

[0020] 2. When the space needs to be expanded, the present invention starts motor 1, and the bevel gear 1 at its output end drives bevel gear 2 to rotate, thereby driving the expansion component that penetrates the bottom of the box to operate. The gear rotates accordingly, and by virtue of the precise meshing with rack 1 and rack 2, rack 2 pushes expansion box 1 to slide smoothly outward along the slide bar 1 fixed at the bottom end of the inner wall of the box and the slide groove 1 at its bottom end. At the same time, rack 1 drives expansion box 2 to expand synchronously along the slide bar 2 and slide groove 2 at the bottom end of the inner wall of expansion box 1, so that the top space expansion is achieved quickly and smoothly, effectively increasing the indoor use area, meeting diverse functional requirements, and creating a more spacious and comfortable environment for users.

[0021] 3. The present invention has a significant effect through the rotating assembly of the side wall legs of the expansion box 1 and the expansion box 2. It is placed in the rotating cavity, connected to the legs by the rotating shaft 1, and the ratchet is fixed by the fixing rod 3. Under different working conditions, the legs rotate, the ratchet is linked, and the pawl clamps the ratchet under the action of the spring to stabilize the legs and solve the problem of insufficient stability.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example:

[0034] Please see attached Figure 1 -Attached Figure 4 The embodiment of the present invention provides an expandable container module room and a construction method thereof, comprising a box body 1, a shell 13 is arranged at the bottom end of the box body 1, two holes are arranged at the bottom of the shell 13, a motor 2 14 is arranged inside the shell 13, a bevel gear 4 23 is fixedly arranged at the output end of the motor 2 14, a bevel gear 3 19 is symmetrically meshed at the tooth end of the bevel gear 4 23, a rotating shaft 2 18 is fixedly arranged in the middle of the bevel gear 3 19, a worm 2 22 is fixedly arranged on both sides of the middle of the rotating shaft 2 18, and the worm 2 The tooth ends of 22 are symmetrically meshed with worm gear 20, the middle part of worm gear 20 is threadedly connected with screw rod 21, the bottom end of screw rod 21 is threadedly connected with base 15, the bottom end of base 15 is fixedly provided with universal wheel 7, worm 12 is fixedly provided with worm gear 12 at both ends of rotating shaft 2, the tooth ends of worm gear 12 are symmetrically meshed with worm gear 17, the middle part of worm gear 17 is threadedly connected with screw rod 16, the bottom end of screw rod 16 is threadedly connected with support 6, and the thread directions of screw rod 16 and screw rod 21 are opposite.

[0035] Specifically, a motor 2 14 is arranged inside the shell 13 at the bottom end of the box body 1. When the operation command is received, the motor 2 14 starts, and the bevel gear 4 23 fixed at its output end starts to rotate. The bevel gear 4 23 meshes with the tooth end of the symmetrically arranged bevel gear 3 19. This meshing structure ensures the efficient transmission of power, so that the bevel gear 3 19 can rotate synchronously and stably with the bevel gear 4 23. The rotating shaft 2 18 firmly fixed in the middle of the bevel gear 3 19 rotates at a high speed driven by the bevel gear 3 19. The rotating shaft 2 18 not only rotates itself, but also transmits power to the transmission components at both ends and both sides of the middle. On both sides of the middle of the rotating shaft 2 18, a worm 2 22 is fixedly installed. As the rotating shaft 2 18 rotates, the worm 2 22 begins to rotate around its own axis. The worm 2 22 is meshed and connected with the tooth end of the worm wheel 2 20. According to the worm transmission principle, the rotation of the worm 2 22 drives the worm wheel 2 20 to rotate around its own central axis. The middle part of the worm wheel 20 is connected with the screw rod 21 through a carefully designed thread. When the worm wheel 20 rotates, the screw rod 21 produces precise axial movement according to the spiral motion characteristics of the thread. The bottom end of the screw rod 21 is threadedly connected to the base 15, and the bottom end of the base 15 is rigidly fixed with a universal wheel 7. Therefore, the axial movement of the screw rod 21 is directly converted into the lifting and lowering action of the universal wheel 7. The worm 12 fixed at both ends of the rotating shaft 218 also rotates with the rotation of the rotating shaft 218. The worm 12 is also meshed with the worm wheel 17, transmitting power to the worm wheel 17, causing the worm wheel 17 to rotate. The screw rod 16 threadedly connected to the middle part of the worm wheel 17, under the drive of the worm wheel 17, is designed according to the thread direction opposite to the screw rod 21, and realizes the axial movement opposite to the screw rod 21. The pillar 6 threadedly connected to the bottom end of the screw rod 16 is also lifted and lowered accordingly. The single power input of the motor 2 14 realizes the coordinated movement of the universal wheel 7 and the support 6, achieving a rapid switch between the moving and supporting states.

[0036] The transmission system driven by the motor 14 at the bottom of the box body 1 realizes the integration of movement and support. When moving, the universal wheel 7 can be quickly and accurately lowered, the support 6 can be raised, the lifting equipment can be removed, and the height can be adjusted according to the ground to ensure smooth movement; after being in place, the support 6 can accurately support, adapt to site conditions, and resist external impact. The problem of inconvenient conversion between support and movement and the problem that the movement of traditional container modular houses depends on lifting, complex operation, inconvenient support adjustment, insufficient precision, and cumbersome conversion between movement and support are solved, and the practicality is improved.

[0037] Please refer to the attached Figure 2 -Attached Figure 3 , Attachment Figure 7 -Attached Fig. 9A shell 2 is provided at the top of the box body 1, and a motor 8 is provided inside the shell 2. A bevel gear 9 is fixedly provided at the output end of the motor 8. The tooth end of the bevel gear 9 is meshedly connected with a bevel gear 2 10. The bottom end of the bevel gear 2 10 passes through the box body 1 and is fixedly provided with an expansion component. The expansion component includes a gear 33. The tooth end of the gear 33 is symmetrically meshedly connected with a rack 1 36 and a rack 2 37. An expansion box 1 3 is fixedly provided at the top of the rack 2 37. A slide groove 1 34 is provided at the bottom end of the expansion box 1 3. A slide bar 2 32 is symmetrically fixedly provided at the bottom end of the inner wall of the expansion box 1 3. The outer wall of the slide bar 2 32 is slidably connected with the expansion box 2 11 through a slide groove 2 35. The top end of the rack 1 36 is fixedly provided at the top end of the inner wall of the expansion box 2 11. The slide groove 1 34 of the expansion box 1 3 is slidably connected with a slide bar 1 31, and the bottom end of the slide bar 1 31 is fixedly provided at the bottom end of the inner wall of the box body 1.

[0038] Specifically, when the space of the container module room needs to be expanded, the motor 18 located inside the top shell 2 of the box body 1 is started. The bevel gear 19 fixed at the output end of the motor 18 rotates accordingly. Since the bevel gear 19 is meshed with the tooth end of the bevel gear 2 10, according to the gear transmission principle, the bevel gear 2 10 rotates synchronously under the drive of the bevel gear 19, and the bottom end of the bevel gear 2 10 passes through the box body 1 and is firmly connected with the expansion component to transmit power to the expansion component. The gear 33 in the expansion component starts to rotate under the drive of the bevel gear 2 10, and the gear 33 is symmetrically meshed with the tooth ends of the rack 1 36 and the rack 2 37. When the gear 33 rotates, according to the gear and rack transmission characteristics, the rack 1 36 and the rack 2 37 will produce relative linear motion. The expansion box 13 fixed at the top of the rack 237 expands outward with the movement of the rack 237. At the same time, the slide bar 232 symmetrically fixed at the bottom of the inner wall of the expansion box 13 slides along the slide groove 235 matched therewith, providing stable guidance and support for the movement of the expansion box 13, ensuring the accuracy of its movement trajectory. The top of the rack 136 is fixed at the top of the inner wall of the expansion box 211. With the movement of the rack 136, the expansion box 211 is also driven to expand outward. In addition, the slide groove 134 at the bottom of the expansion box 13 is tightly slidably connected with the slide bar 131 fixed at the bottom of the inner wall of the box body 1. This structure further limits the movement direction of the expansion box 13 and the expansion box 211, so that they can only expand smoothly along the predetermined direction, ensuring the reliability and stability of the entire expansion process.

[0039] Through the expansion components driven by the motor 8 of the container module room, the space can be expanded quickly and smoothly, the usable area can be increased, and the slide bar and the slide groove can cooperate to ensure smooth operation, reduce wear and tear, and efficiently use the top space; it also solves the problems of fixed space, unstable expansion, complex operation and insufficient space utilization of traditional containers, and improves versatility.

[0040] Please see attached Figure 1 -Attached Figure 3 , Attachment Figure 5 -Attached Figure 6 The side walls of the extension box 1 3 and the extension box 2 11 are symmetrically provided with supporting legs 4, a rotating chamber 25 is provided on one side of the supporting leg 4, a rotating assembly is provided on the outer wall of the supporting leg 4, and the rotating assembly is arranged inside the rotating chamber 25, the rotating assembly includes a rotating shaft 1 5, the outer wall of the rotating shaft 1 5 is rotatably connected to the outer wall of the supporting leg 4, a ratchet 24 is fixedly provided on the outer wall of the rotating shaft 1 5, a fixing rod 3 38 is fixedly provided on one side of the ratchet 24, the fixing rod 3 38 passes through 24 and is fixed inside the supporting leg 4, a pawl 26 is connected to the tooth end of the ratchet 24, one end of the pawl 26 is rotatably connected to the rotating shaft 4 27, one end of the rotating shaft 4 27 is fixedly provided on the side walls of the extension box 1 3 and the supporting leg 4, a fixing rod 2 30 is fixedly provided on one side of the other end of the pawl 26, a spring 29 is provided on the outer wall of the fixing rod 2 30, one end of the spring 29 is provided with a fixing rod 1 28, and one end of the fixing rod 1 28 is fixedly provided on the side walls of the extension box 1 3 and the supporting leg 4.

[0041] Specifically, when it is necessary to operate the legs 4 on the side walls of the extension box 13 and the extension box 211, external force is applied to the legs 4, so that they rotate in the rotating chamber 25 with the rotating shaft 15 as the axis. The rotating connection between the rotating shaft 15 and the outer wall of the leg 4 ensures that the leg 4 can change its angle, and the rotating chamber 25 provides a relatively closed operating space for the rotating assembly to avoid interference from external debris. The ratchet 24 fixed on the outer wall of the rotating shaft 15 will rotate synchronously with the leg 4, and the fixed rod 3 38 on one side of the ratchet 24 penetrates the ratchet 24 and is firmly fixed inside the leg 4, further enhancing the connection stability between the ratchet 24 and the leg 4, so that it can accurately transmit the movement state of the leg 4. The tooth end of the ratchet 24 cooperates with the pawl 26, and one end of the pawl 26 is rotatably connected to the side walls of the extension box 13 and the leg 4 through the rotating shaft 4 27, so that it can swing freely to adapt to the meshing action with the ratchet 24. Under the action of the spring 29, one end of the spring 29 is connected to the fixing rod 2 30, and the fixing rod 2 30 is fixed to one side of the other end of the pawl 26. The other end of the spring 29 is connected to the fixing rod 1 28, and the fixing rod 1 28 is fixed to the side wall of the extension box 1 3 and the leg 4. The spring 29 always applies a thrust to the pawl 26 toward the tooth end of the ratchet 24. When the leg 4 is deployed outward, the ratchet 24 rotates counterclockwise, and the pawl 26 is quickly stuck in the tooth groove of the ratchet 24 under the elastic force of the spring 29, preventing the ratchet 24 from reversing, thereby firmly fixing the leg 4 in the deployed position; when the leg 4 needs to be retracted, an external force needs to be applied to overcome the elastic force of the spring 29 to lift the pawl 26, so that the ratchet 24 can rotate clockwise, thereby realizing the smooth retraction of the leg 4.

[0042] By extending the rotating assembly of the legs 4 of the box, the legs 4 can be reliably adjusted and fixed in angle, folded during transportation, and unfolded as needed during use. It can also adapt to complex terrain and ensure the stability and safety of the box. It solves the problem of insufficient stability of the legs 4 and difficulty in flexibly responding to working conditions, enhances safety in use, and improves versatility.

[0043] Please see attached Figure 1 -Attached Fig. 9 , an expandable container module house and a construction method thereof, comprising the following steps:

[0044] S1. Produce the overall structural components in the factory to ensure that the size and quality meet the requirements, manufacture the transmission components, and install the motor 1 8 and the motor 2 14 to the corresponding positions, connect the corresponding transmission components to ensure accurate meshing, prefabricate the sliding connection components and install them to the corresponding positions, and assemble the rotating components of the leg 4 to ensure its reliability;

[0045] S2. Pack the prefabricated components and pre-install the modules of some transmission mechanisms, transport them to the construction site, pay attention to protecting the precision components, level the site and do foundation treatment on site, and prepare auxiliary equipment;

[0046] S3. Place the box 1 on the foundation, start the motor 2 14, adjust the positions of the universal wheels 7 and the support 6 through the transmission mechanism to make the box 1 initially stable, start the motor 1 8, and drive the expansion box 1 3 and the expansion box 2 11 to expand outward through the transmission mechanism to achieve space expansion. During the expansion process, check the rotation assembly of the support leg 4. After the assembly is completed, perform a comprehensive debugging and inspection to ensure that all functions are normal.

[0047] Specifically, in a factory environment, according to precise design drawings, professional processing equipment is used to produce the box 1, shell 2, extension box 1 3, extension box 2 11, leg 4 and other integral structural components. Through strict quality inspection processes and precision measuring tools, the dimensional tolerance of each component is controlled within a very small range to meet the assembly requirements. Synchronously manufacture the transmission components of motor 1 8, motor 2 14, bevel gear 1 9, bevel gear 2 10, bevel gear 3 19, bevel gear 4 23, gear 33, rack 1 36, rack 2 37, worm 1 12, worm 2 22, worm wheel 1 17, worm wheel 2 20, screw 1 16, screw 2 21. Accurately install motor 1 8 into the preset installation position inside the shell 2, and firmly fix motor 2 14 at the designated position inside the shell 13. Then, according to the precise meshing principle of gear 33 transmission, carefully install and adjust the bevel gear 33, worm, worm wheel and other components to make the tooth surface contact even and the gap reasonable, so as to ensure efficient and stable power transmission. The slider 1 31, slider 2 32, slot 1 34, and slot 2 35 in the prefabricated extension assembly are tightly embedded in the corresponding groove at the bottom of the inner wall of the box body 1 according to the requirements of precise matching. The slider 2 32 is accurately fixed to the bottom of the inner wall of the extension box 1 3. The slot 1 34 is tightly assembled with the bottom of the extension box 1 3. The slot 2 35 is accurately installed on the extension box 2 11. Through repeated debugging of the sliding fit, it is ensured that the sliding is smooth without looseness or jamming. Assemble the rotating assembly on the leg 4, combine the ratchet 24, pawl 26, spring 29, fixed rod 1 28, fixed rod 2 30, shaft 1 5, and shaft 4 27 in sequence, and finely adjust the parameters such as the elastic force of the spring 29 and the meshing angle between the pawl 26 and the ratchet by simulating the actual working condition test to ensure that the rotating assembly can operate stably and reliably under different stress conditions.
