Description

Technical Field

[0001] This invention relates to the field of container transportation technology, and in particular to a modular building container transportation bracket that is three-way adjustable and its usage method. Background Technology

[0002] Modular construction is a new type of construction method that involves breaking down a building into multiple independent box modules, completing the multi-disciplinary integration and processing of the box modules in the factory, and then transporting them to the construction site for hoisting.

[0003] During transportation, in order to ensure even stress distribution and avoid damage to the container modules, a special transport bracket is usually required between the transport vehicle and the container to support the container. However, different containers vary greatly in size, weight, and shape, which places higher demands on the applicability of the transport bracket.

[0004] Currently, Chinese patent CN202321624737.1 discloses a modular integrated building box transport frame. By setting flexible pads and shock-absorbing seats on the transport frame frame and crossbeams of fixed size, the vibration and hard collision of the box during transportation are reduced, thereby avoiding wear and cracking of the box. Chinese patent CN202511161275.8 discloses a modular house transport bracket, which disassembles the bracket into a fixed frame and movable frames on both sides of the fixed frame. By rotating the threaded rod at the bottom of the frame, a slider is driven to move, thereby causing the movable frames to move relative to the fixed frame, achieving the effect of adjusting the transport bracket in one direction. However, it still has the following shortcomings: (1) Most existing transport brackets cannot be adjusted in size or can only be adjusted in one direction, such as height or angle. They are difficult to meet the position adjustment requirements of the box in the length, width and vertical directions at the same time, and cannot be well adapted to complex scenarios. As a result, when transporting different types of boxes, it is necessary to prepare a variety of different brackets, which increases equipment costs and management difficulty.

[0005] (2) Existing fixing methods, such as tightening with bolts or binding with cables, are relatively complicated and require a lot of time and manpower to complete the fixing or unlocking operations. In large-scale cargo transportation or emergency transportation tasks, this will seriously affect transportation efficiency and increase transportation costs. Moreover, after long-term use, these fixing components are prone to wear and loosening, which reduces the reliability of fixing. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned shortcomings by providing a modular building container transport bracket with three-way adjustable dimensions and its usage method. This allows for adjustment of dimensions in three directions: length, width, and height. The modular building container transport bracket can be quickly unlocked and fixed, enabling rapid and continuous adjustment of the bracket.

[0011] Furthermore, the lowering plate support includes a single sliding base disposed on the π-shaped slider, the top of which is fixedly connected to the L-shaped plate.

[0012] Furthermore, the double-jointed support is located at the junction of the bottom plate of the lowered plate area and the bottom plate of the higher plate area; The double support includes a double sliding base disposed on the top of the π-shaped slider. The top of the double sliding base is fixedly connected to the L-shaped plate and the lifting device, respectively. The top of the lifting device is fixedly connected to the L-shaped plate.

[0013] Furthermore, the L-shaped plate includes a fixed plate disposed on the top of the support and a side plate disposed on the fixed plate, and both the fixed plate and the side plate are provided with buffer pads; It also includes slide rods symmetrically arranged at the bottom of the side plate and inserted into the fixed plate, and adjusting bolts arranged in the side plate and connected to the fixed plate.

[0014] Furthermore, the secondary beam includes an inner sleeve disposed between the two beam columns and an outer sleeve disposed on the outer wall of the inner sleeve; It also includes a through hole provided at the junction of the outer sleeve and the inner sleeve, and a pin inserted into the through hole.

[0016] The method of using the three-way adjustable modular building container transport bracket includes the following steps: S1. Length direction adjustment: Based on the double support, according to the length of the bottom plate of the box lowering area, unlock the support locking device of the lowering support and drag the lowering support to the corresponding position to lock it. Similarly, the high plate support is adjusted according to the length of the bottom plate of the box high plate area. Usually, only 1-2 high plate supports at the end need to be adjusted to complete the length matching of the bracket to the high plate area. S2. Width adjustment: Pull out the pin between the outer sleeve and the inner sleeve of the secondary beam, move the main beam on the same side as the inner sleeve as a whole, adjust it to a position that adapts to the width of the box, and then insert the pin to fix the secondary beam. S3. Height adjustment: Based on the height difference between the bottom plate of the lowered plate area and the bottom plate of the high plate area, rotate the rocker wheel of each worm gear screw lifting device to adjust the height of all high plate supports to the appropriate position. S4. Using lifting equipment, steel wire ropes are passed through the lifting lugs to lift the entire transport bracket onto the flatbed of the transport vehicle. Then, steel wire ropes, straps and other tools are used to pass around the collars on the main beam and the fixed device of the carriage to securely connect the transport bracket to the transport vehicle. S5. Lift the modular building box using a lifting device and place it on the transport bracket. Align the bottom lower plate and the upper plate of the box with the lower plate support and the upper plate support of the transport bracket, respectively. The junction of the bottom lower plate area and the upper plate area of ​​the box is located on the double support. Tighten the adjusting bolts on the side plate of the L-shaped plate to clamp the box with the L-shaped plate.

[0017] S6. After checking that the container is secure and taking necessary protective measures during transport, it can be transported. S7. When transporting containers of different sizes, loosen the connection between the transport bracket and the carriage, use lifting equipment to lower the transport bracket to the ground, and repeat steps S1-S6 according to the size of the container to be transported.

[0018] The beneficial effects of this invention are reflected in: 1. This invention can adapt to boxes of various planar sizes by changing the length and width of the bracket, and can adapt to boxes of different drop heights by changing the height of the support legs of the high plate support, so that the transport bracket can meet the transportation needs of modular building boxes of various sizes.

[0019] 2. In this invention, the three stages of unlocking, moving, and locking of the support locking device can be quickly completed by rotating or pulling the handle. The inner and outer sleeves adopt a key-type method for quick locking / unlocking. The worm gear screw lifting device can quickly adjust the height of the support leg by hand-cranking the wheel. The above three methods enable the transport bracket to quickly complete the size adjustment.

[0020] 3. This invention employs a worm gear screw lifting device, which allows for continuous and minute adjustment of the support leg height to accommodate different height differences between the lower and upper plates of the container. It enables dimensional adjustment in three directions: length, width, and height, and allows for quick unlocking of the fixed modular building container transport bracket, thus achieving rapid and continuous adjustment of the bracket.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-13 This invention discloses a modular building container transport bracket with three-way adjustable design and its usage method, including: The main beam 1 includes two parallel beam columns, a sliding groove 12 respectively set on the opposite side of the two beam columns, and a rack 14 set on the opposite side of the two beam columns. The beam columns are provided with lifting lugs 11 and collars 13. The two beam columns are fixedly installed with lifting lugs 11 at both ends. At least two collars 13 are also installed on the outer side of the two beam columns along the length direction. The collars 13 are connected to the fixing device on the carriage of the transport vehicle by means of steel wire rope, straps, etc., so that the frame is stably connected to the transport vehicle. Secondary beam 2, at least two sets, is transversely connected between two beams and columns. Secondary beam 2 is used to adjust the spacing between the two beams and columns. Cross bars 3 are respectively set between the two secondary beams 2, and open and close synchronously with the extension and retraction of the secondary beams 2. Cross bars 3 are used to enhance the stability of the main body; Support 4 includes a drop plate support 41, a double support 42, and a high plate support 43, which are slidably mounted on the main beam 1 and fixedly connected to the secondary beam 2, respectively; A π-shaped slider 46 is disposed on one side of the support 4 and is slidably connected to the slide groove 12; The housing 5 includes a lowered plate area bottom plate 51 disposed on the top of the lowered plate support 41 and a high plate area bottom plate 52 disposed on the top of the high plate support 43. Lifting devices 45 are respectively installed on the top of one side of the double support 42 and the top of the high plate support 43, and are used to adjust the height of the support 4 to adapt to the height difference structure at the bottom of the box 5. L-shaped plates 44 are respectively set on the top of the lowering plate support 41 and the lifting device 45 to support and laterally clamp the box 5. The top of the lifting device 45 and the L-shaped plates 44 are fixedly installed by welding or bolts to support the bottom plate 52 of the high plate area of ​​the box 5. The height of the high plate support 43 can be changed by adjusting the lifting device 45 to adapt to the box 5 with different lowering plate heights. The locking device 47 is located on the inner side of the support 4 and engages with the rack 14 to quickly lock and unlock the support 4 and the rack 14.

[0025] In a specific embodiment, the locking device 47 includes a fixing plate 473 disposed inside the lowering plate support 41, and a locking rod 471 that engages with the rack 14 through a round hole penetrating the inside of the fixing plate 473. The bottom of the locking rod 471 is fixedly provided with a toothed joint that meshes with the rack 14, and the bottom of the fixing plate 473 is located on the outer wall of the locking rod 471. It also includes locking blocks 474 symmetrically arranged on both sides of the locking rod 471 and fixedly installed with the lowering plate support 41, and a connecting rod handle 475 rotatably arranged in the locking block 474; It also includes a second elastic member 476 disposed on the locking block 474 and sleeved on the outer wall of the connecting rod handle 475, and a trapezoidal wedge block 477 rotatably disposed at the end of the connecting rod handle 475 and slidably connected to the locking rod 471, the trapezoidal wedge block 477 sliding along the locking block 474 in the horizontal direction.

[0026] In one embodiment, the linkage handle 475 includes a rotating rod 4751 that passes through the locking block 474 and is rotatably connected to the trapezoidal wedge block 477, and an arc-shaped block 4752 disposed on the rotating rod 4751 and cooperating with the locking block 474. The arc-shaped block 4752 is used to lock the locking block 474 and the rotating rod 4751. An arc-shaped groove 4741 adapted to the arc-shaped block 4752 is provided on the locking block 474. It also includes a rotating handle 4753 located at the end of the rotating rod 4751.

[0027] In use, the relative position of the support 4 and the main beam 1 is locked. The first elastic element 472 is sleeved on the locking rod 471, with one end contacting the lower part of the locking rod 471 and the other end contacting the lower surface of the fixing plate 473, so that the locking rod 471 is in a downward pressing state. The rotating rod 4751 with the connecting handle 475 passes through the locking block 474 and is rotatably connected to the trapezoidal wedge block 477. The rotating rod 4751 has an arc-shaped block 4752, which can slide out / slide into the arc-shaped groove 4741 of the locking block 474 when the rotating rod 4751 rotates, so that the rotating rod 4751 can slide out / slide into the arc-shaped groove 4741 of the locking block 474 when the rotating rod 4751 rotates, so that the rotating rod 4751 can be in the main beam 1 along the length of the main beam 1. Unlocking / locking in the direction of degree: The trapezoidal wedge 477 matches the top wedge of the locking rod 471. When the rotating rod 4751 is rotated to disengage the arc block 4752 from the arc groove 4741, the device is unlocked. When the handle with connecting rod 475 is pulled in the length direction of the main beam 1, the trapezoidal wedge 477 moves horizontally, and the inclined surface of its top wedge slides relative to the inclined surface of the top wedge of the locking rod 471, pushing the locking rod 471 to move upward. When the lower tooth of the locking rod 471 disengages from the rack 14, the support 4 can be moved in the length direction of the main beam 1 by continuing to pull the rotating handle 4753. When the support 4 moves to the predetermined position, the rotating handle 4753 is released, the second elastic element 476 pushes the trapezoidal wedge block 477 to reset, causing the locking rod 471 to fall back into position. The lower toothed part of the locking rod 471 inserts into the rack 14, and the support 4 is locked again. Then, the rotating handle 4753 is rotated to make the arc block 4752 rotate into the arc groove 4741, and the rotating rod 4751 is locked again to prevent personnel from accidentally touching it and causing the support 4 to shift.

[0028] In a specific embodiment, the lifting device 45 includes a support cylinder 459 respectively disposed on the top of one side of the double support 42 and the top of the high plate support 43, and a housing 451 disposed on the top of the support cylinder 459. The bottom of the housing 451 is provided with a lower cover plate 4521 fixedly connected to the support cylinder 459, and the top of the housing 451 is provided with a cover plate 4522. It also includes a lifting screw 457 rotatably mounted on the top of one side of the double support 42 and the top of the high plate support 43, and a worm wheel 455 threadedly connected to the outer wall of the lifting screw 457 and located in the housing 451. The worm wheel 455 is threadedly connected to a worm 453. One end of the worm 453 extending to the outer wall of the housing 451 is provided with a rocker wheel 456. Both ends of the worm 453 are respectively provided with bearings 454 fixedly connected to the housing 451. It also includes a lifting platform 458 rotatably mounted on top of the lifting screw 457. The lifting platform 458 is fixedly connected to the L-shaped plate 44. A limit rod 4581 is provided on one side of the lifting platform 458. The limit rod 4581 slidably penetrates the through hole at the corresponding position of the lower cover plate 4521. The inner sleeves 22 of the main beam 1 and the secondary beam 2, as well as the limit rod 4581, are all marked with graduations to facilitate precise control when adjusting the size of the transport bracket. The graduations are engraved to reduce wear. The lifting screw 457 rotates when it moves up and down, and its top is rotatably connected to the lifting platform 458. The limiting rod 4581 of the lifting platform 458 passes through the corresponding through hole of the lower cover plate 4521, so that the lifting platform 458 can move up and down with the lifting screw 457 without rotating. This also prevents the L-shaped plate 44 connected to the top of the lifting platform 458 from rotating, ensuring that the box 5 can be lowered and aligned. In use, the worm 453 is rotated by hand-cranking the rocker wheel 456. The worm 453 meshes with the gear of the worm wheel 455, causing the worm wheel 455 to rotate. The thread of the center hole of the worm wheel 455 pushes the lifting screw 457 to move up and down, thereby realizing the continuous adjustment of the height of the support 4.

[0029] In one embodiment, the lowering plate support 41 includes a single sliding base 411 disposed on a π-shaped slider 46. The top of the single sliding base 411 is fixedly connected to an L-shaped plate 44. The single sliding base 411 moves on the main beam 1 and is locked by a locking device 47. The L-shaped plate 44 is used to support the bottom plate 51 of the lowering plate area of ​​the box body 5.

The top of the double-link sliding base 421 is fixedly connected to the L-shaped plate 44 and the lifting device 45 respectively. The top of the lifting device 45 is fixedly connected to the L-shaped plate 44. The double-link support 42 is composed of the double-link sliding base 421, the L-shaped plate 44 and the worm gear screw lifting device 45. The fixing method of the double-link sliding base 421 to the main beam 1 is the same as that of the single sliding base 411. The top of the double-link sliding base 421 has two docking sleeves. The L-shaped plate 44 is fixed on the top of the docking sleeve near the bottom plate 51 of the lower plate area. The lifting device 45 is installed on the docking sleeve near the bottom plate 52 of the higher plate area. Taking the double-link support 42 as the boundary, the side where the docking sleeve is fixed to the L-shaped plate 44 is the lower plate support 41, and the other side where the docking sleeve is connected to the lifting device 45 is the higher plate support 43.

[0031] In one embodiment, the L-shaped plate 44 includes a fixed plate 441 disposed on the top of the support 4 and a side plate 442 disposed on the fixed plate 441. Both the fixed plate 441 and the side plate 442 are provided with buffer pads 443. It also includes a sliding rod 445 symmetrically arranged at the bottom of the side plate 442 and inserted into the fixing plate 441, and an adjusting bolt 444 arranged in the side plate 442 and connected to the fixing plate 441. The side plate 442 and the fixing plate 441 have bolt holes and the side plate 442 is fixed to the side of the fixing plate 441 by the adjusting bolt 444. The side plate 442 is clamped to the side of the box body 5 by adjusting the bolt 444. The fixing plate 441 and the side plate 442 are in contact with the box body 5 through the buffer pad 443 to prevent the box body structure from being damaged by bumps.

[0032] In a specific embodiment, the secondary beam 2 includes an inner sleeve 22 disposed between the two beams and columns, and an outer sleeve 21 disposed on the outer wall of the inner sleeve 22; It also includes a through hole set in the outer sleeve 21 and the inner sleeve 22, and a pin 23 inserted into the through hole. The outer wall of the outer sleeve 21 is provided with a symmetrical C-shaped rectangular groove 24. The outer sleeve 21 is sleeved with the inner sleeve 22, and the pin 23 is inserted into the through hole of the outer sleeve 21 and the inner sleeve 22 to realize the length adjustment of the secondary beam 2. The two ends of the secondary beam 2 are fixedly connected to the support 4 by welding or bolts.

[0033] In one embodiment, the cross bar 3 includes a fixed connector 33 disposed on one side of the secondary beam, a sliding connector 32 disposed in the C-shaped rectangular groove 24, and a cross support bar 31 disposed on the sliding connector 32. The cross support bar 31 is provided with a pin in the middle. The fixed connector 33 is used to fix one side of the cross bar 3 to the outer sleeve 21, and the other side of the cross bar 3 slides on the inner sleeve 22 through the sliding connector 32. The sliding connector 32 includes a protrusion 321 disposed within the C-shaped rectangular groove 24; The cross support rod 31 includes a perforated joint 311 rotatably mounted on the protrusion 321. The sliding connector 32 is slidably installed in the C-shaped rectangular groove 24 of two adjacent secondary beams 2 through the protrusion 321 on it, and is connected to the perforated joint 311 through the pin 23, so that the cross rod 3 is installed between two adjacent secondary beams 2, and can open and close synchronously with the movement of the support 4 and the change of the spacing of the secondary beams 2, thereby enhancing the stability of the frame.

[0034] The method of using the three-way adjustable modular building container transport bracket includes the following steps: S1. Length direction adjustment: Taking the double support 42 as the reference, according to the length of the bottom plate 51 of the lower plate area of ​​the box 5, unlock the support locking device 47 of the lower plate support 41 and drag the lower plate support 41 to the corresponding position to lock it. Similarly, the high plate support 43 is adjusted according to the length of the bottom plate 52 of the high plate area of ​​the box 5. Usually, only 1-2 high plate supports 43 at the end need to be adjusted to complete the length matching of the bracket to the high plate area. S2. Width adjustment: Pull out the pin 23 between the outer sleeve 21 and the inner sleeve 22, move the main beam 1 on the same side as the inner sleeve 22 as a whole, adjust it to a position that is compatible with the width of the box body 5, and then insert the pin 23 to fix the secondary beam 2. S3. Height adjustment: Based on the height difference between the bottom plate 51 of the lower plate area and the bottom plate 52 of the upper plate area of ​​the housing 5, rotate the rocker wheel 456 of each worm gear screw lifting device 45 to adjust the height of all the upper plate supports 43 to the appropriate position.

[0035] S4. Using lifting equipment, the steel wire rope is passed through the lifting lug 11 to lift the entire transport bracket onto the flatbed of the transport vehicle. Then, steel wire rope, straps and other tools are used to pass around the collar 13 on the main beam 1 and the fixed device of the carriage to make the transport bracket and the transport vehicle securely connected. S5. Lift the modular building box 5 using lifting equipment and place it on the transport bracket.
