Description
Technical Field
[0001] This invention belongs to the field of building construction technology, specifically relating to a fastening device, fixing structure, and moving and fixing method for a large mobile factory. Background Technology
[0002] Mobile factories are a type of movable and reusable industrial building, primarily used in fields such as construction, industrial production, and logistics warehousing to support production. Common mobile factories include prefabricated houses or modular units used for steel bar processing and cement storage on construction sites. These types of factories typically have a single-side dimension of less than 10 meters and a self-weight of less than 10 tons. Their relatively small size and weight allow for flexible transport via hoisting. However, when the size and weight of a mobile factory are excessively large, simple hoisting cannot achieve the flexible and rapid turnover of the factory on the production site. Large construction sites located in remote areas with no readily available concrete supply typically require the construction of on-site industrial plants for concrete processing. These plants generally have a span of 30-42 meters and a height of up to 37 meters. As the site changes, these concrete processing plants need to be moved promptly to meet production demands. Similarly, large shipyards require different workspaces and locations at different stages of hull manufacturing. Mobile workshops are used to adapt to these varying process requirements. For example, mobile workshops used for welding hull components in large shipyards are typically around 30 meters long and wide, up to 23 meters high, and weigh over 300 tons. These large mobile workshops are too large and inconvenient to transport directly by crane.
[0003] Currently, to facilitate the transfer and fixation of these large factory buildings, guide rails are generally fixed to the ground. Multiple sliders, adapted to the guide rails and capable of moving along their length, are installed at the bottom of the factory building. When the large mobile factory building is driven along the guide rails, the sliders move relative to the rails to achieve the movement of the entire factory building on the rails. When fixing the factory building, pins are used to connect the sliders and the rails, horizontally positioning the factory building on the guide rails. Positioning this type of large factory building requires pre-drilling holes at corresponding positions on the rails according to the required fixed location, allowing the sliders and rails to connect via pins. Multiple moves and fixations of the factory building necessitate multiple drilling operations on the rails, which is not only cumbersome but also affects the overall strength of the rails, impacting the safety and stability of the factory building's erection.
[0004] In addition, some large mobile factories are located in deserts or along the coast. For example, large mobile factories in shipyards are located by the sea and are frequently exposed to typhoons. Some large concrete processing factories on construction sites are located in deserts and are constantly exposed to wind and sand. These areas experience frequent strong winds, sometimes reaching force 10. The factories are also large in length, width, and height, making them more susceptible to the effects of wind. The existing positioning structure of these large mobile factories only connects the slider and the rail with pins. The contact surface between the pin and the rail is singular. When strong winds hit the factory, the pin is directly subjected to concentrated shear force. Over time, this can easily cause the pin to bend, deform, or even break, leading to derailment accidents. At the same time, the multiple drilled holes in the rails result in insufficient strength and there is also a risk of rail deformation and damage, posing a safety hazard to the long-term stable movement of the factory on the rails.

[0014] A fixed structure for a large mobile factory includes a factory building and a guide rail fixedly installed on the ground. The guide rail is parallel to the horizontal plane and has guide grooves on both sides in the horizontal direction. The length direction of the guide grooves is arranged in the same direction as the length direction of the guide rail. The bottom of the factory building is provided with multiple supporting beams, which are parallel to the guide rail; the supporting beams are provided with multiple sets of large mobile factory building fastening devices as described above, and the multiple sets of fastening devices are arranged at intervals along the length direction of the guide rail; the guide rail is located between the first clamping plate and the second clamping plate, and the claws on the first clamping plate and the second clamping plate are respectively located in the guide grooves on both sides of the guide rail; When the large mobile factory fastening device is fixedly installed on the guide rail, the first clamp and the second clamp respectively abut against the two side walls of the guide rail in the horizontal direction, the claws on the first clamp and the claws on the second clamp respectively abut against the bottom wall of the guide groove, and the top surface of the claws abuts against the upper side wall of the guide groove.
[0015] The method for moving and positioning the factory building in the fixed structure of a large mobile factory building includes the following steps: S1. Rotating the lifting handwheel causes the lifting screw to move downward in a straight line, while simultaneously driving the lifting connecting rod to move downward along the length direction of the guide bar hole. The lifting connecting rod drives the first clamping plate and the second clamping plate and the clamping claws on them to move downward synchronously, so that the top surface of the clamping claws and the upper side wall of the guide groove on the guide rail are arranged at intervals. S2. Rotate the adjustment handwheel to drive the adjustment screw to rotate. The adjustment screw simultaneously drives the first clamping plate and the jaws on it to move away from the second clamping plate. The second clamping plate and the jaws on it move away from the first clamping plate so that the jaws are completely spaced apart from the guide groove. S4. Pull the factory building to the target position along the length of the guide rail; S5. Reverse rotation of the adjustment handwheel causes the adjustment handwheel to drive the adjustment screw to rotate. The adjustment screw simultaneously drives the first clamping plate and the second clamping plate and the jaws on them to move towards each other until the clamping surfaces of the jaws on the first clamping plate and the second clamping plate slide into contact with the groove wall of the guide groove. S6. Rotate the lifting handwheel in the opposite direction to make the lifting screw move upward in a straight line, while pulling the lifting connecting rod upward along the length direction of the guide bar hole. The lifting connecting rod simultaneously pulls the first clamping plate and the second clamping plate and their clamping claws upward until the top surface of the clamping claws abuts against the upper side wall of the guide groove on the guide rail. S7. Repeat step S5 to clamp the guide rail along the horizontal direction perpendicular to the guide rail by the two opposite faces of the jaws on the first and second clamps.
[0016] Compared with the prior art, the beneficial effects of the present invention are: it provides a fastening device, fixing structure, and moving and fixing method for a large mobile factory building. By rotating the lifting handwheel and the adjusting handwheel, the fastening connection / sliding fit state between the factory building and the guide rail can be switched, allowing for flexible and convenient fastening and moving of the factory building on the guide rail. Fastening and fixing on the guide rail can be achieved without drilling holes, improving the strength and safety of the guide rail. The operation is simple and saves manpower. Furthermore, the paired grippers on the large mobile factory building in this invention can not only clamp and fasten to the guide rail, but also, by rotating the lifting handwheel, engage the grippers with the upper guide groove. The sidewalls feature vertical limiting, increasing the contact area between the gripper and the guide rail. This prevents the gripper from sliding up and down in the guide groove during strong winds, ensuring the stability and safety of the large mobile factory building in windy areas. Since the factory building may sway when subjected to strong winds, this invention uses a hinged design for the lifting screw and lifting linkage. This allows the factory building to sway adaptively relative to the lifting linkage, gripper, and guide rail when it is firmly fixed to the guide rail. This prevents the lifting screw, lifting linkage, clamping plate, gripper, and other structures from being directly subjected to bending and shearing forces, thus avoiding deformation and breakage. This further improves the reliability and safety of the factory building's erection. Attached Figure Description

Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0019] As attached Figure 1-7As shown, a fastening device for a large mobile factory building includes a lifting handwheel 2 mounted on a support beam 91 at the bottom of the factory building 9. The lifting handwheel 2 has a threaded through hole with its axis perpendicular to the top surface of the support beam 91 and is rotatably connected to the support beam 91 around the axis of the threaded through hole. A lifting screw 3 is threaded into the threaded through hole, and a lifting connecting rod 4 parallel to the horizontal plane is hinged to the lower end of the lifting screw 3. A guide seat 5 is fixedly mounted on the lower part of the support beam 91. The guide seat 5 has guide strip holes 51 arranged vertically in the vertical direction. The lifting connecting rod 4 is located within the guide strip holes 51 and slides in the vertical direction with the guide strip holes 51. A first clamping plate 61 and a second clamping plate 62 are vertically connected to the lifting connecting rod 4 and slide in the axial direction with it. The first clamping plate 61 and the second clamping plate 62 are each provided with opposing clamping claws 60 at their lower ends. The top surface of the clamping claws 60 is adapted to the shape of the guide grooves 11 on both sides of the guide rail 1. The first clamping plate 61 is provided with a first nut 63, and the second clamping plate 62 is provided with a second nut 64. It also includes an adjusting screw 7 that vertically penetrates the first clamping plate 61 and the second clamping plate 62. One end of the adjusting screw 7 is fixed with an adjusting handwheel 70. The outer wall of the adjusting screw 7 is provided with a first threaded section 71 and a second threaded section 72 with opposite thread directions. The first nut 63 is sleeved on the outside of the adjusting screw 7 and threadedly connected to the first threaded section 71. The second nut 64 is sleeved on the outside of the adjusting screw 7 and threadedly connected to the second threaded section 72. At least two guide rails 1 parallel to the horizontal plane are provided on the ground below the large mobile factory building. Both sides of the guide rail 1 in the horizontal direction have guide grooves 11 arranged along the length of the guide rail 1. The guide rails 1 can be fixed to the ground by casting, bolting, or other methods. Factory building 9 is an existing steel structure factory building, and the supporting beams 91 on it are arranged along the length of factory building 9. The supporting beams 91 are parallel to the guide rails 1.
[0020] This invention allows the adjusting screw 7 to rotate in either the forward or reverse direction by rotating the adjusting handwheel 70. The adjusting screw 7 cooperates with the first nut 63 and the second nut 64 to form two sets of screw pairs, thereby converting the rotation of the adjusting screw 7 into the opposing or opposing movements of the first nut 63 and the second nut 64 along the axial direction of the adjusting screw 7. This, in turn, drives the jaws 60 of the first clamping plate 61 and the jaws 60 of the second clamping plate 62 to move towards each other or away from each other. By rotating the lifting handwheel 2 relative to the lifting screw 3, the lifting handwheel 2 moves up and down. The lifting screw 3 drives the lifting connecting rod 4 and the first clamping plate 61 and the second clamping plate 62 to move up and down synchronously, thereby realizing the lifting and lowering movement of the jaws 60. In summary, rotating the adjusting handwheel 70 allows for the horizontal clamping distance adjustment of the jaws 60 on the first clamping plate 61 and the jaws 60 on the second clamping plate 62, and rotating the lifting handwheel 2 allows for the vertical position adjustment of the jaws 60.
[0021] When the large-volume mobile factory building fastening device of the present invention is used to position the factory building 9 on the guide rail 1, the clamping claws 60 on the first clamping plate 61 and the second clamping claw 62 are respectively located in the guide grooves 11 on both sides of the guide rail 1. The top surface of the clamping claw 60 abuts against the upper side wall of the guide groove 11. The two clamping claws 60 cooperate with each other to clamp in the horizontal direction perpendicular to the guide rail 1. The lifting screw 3 and the lifting connecting rod 4 are in a tensioned connection state. The entire support beam 91 is fastened and fixed on the guide rail 1 by the clamping claws 60, thereby realizing the fastening and fixing of the large-volume mobile factory building. When moving the large-volume mobile factory building of the present invention on the guide rail 1, the lifting handwheel 2 and the adjusting handwheel 70 are rotated respectively so that the top surface and clamping surface of the two clamping claws 60 are spaced apart from the guide rail 1. The factory building 9 can be moved horizontally by pulling along the length direction of the guide rail 1. When the factory building 9 is moved to the designated position, the lifting handwheel 2 and the adjusting handwheel 70 are rotated again so that the top surfaces of the two grippers 60 and the gripper 60 abut against the upper side wall of the guide groove 11. The two grippers 60 cooperate with each other to clamp in the horizontal direction perpendicular to the guide rail 1, thereby achieving the fixed position of the entire factory building on the guide rail 1.
[0022] The large mobile workshop described in this invention allows for switching between the tight connection / sliding fit state of the workshop 9 and the guide rail 1 by rotating the lifting handwheel 2 and the adjusting handwheel 70. This enables flexible and convenient positioning and movement of the workshop 9 on the guide rail, eliminating the need for drilling holes in the guide rail 1, thus improving the strength and safety of the guide rail 1. The operation is simple and saves manpower. Furthermore, the paired grippers 60 on the large mobile workshop not only clamp and secure the workshop 9 to the guide rail 1, but also allow for vertical positioning by rotating the lifting handwheel and engaging the grippers 60 against the upper side wall of the guide groove 11. This increases the contact area between the grippers 60 and the guide rail 1, improving the connection between the workshop 9 and the guide rail. The tight connection prevents the gripper 60 from sliding up and down in the guide groove 1 when the wind is strong, ensuring the stability and safety of the large mobile factory building in areas with strong winds. When the factory building 9 is blown by strong winds, it may sway. The present invention sets the lifting screw 3 and the lifting connecting rod 4 as hinges so that when the factory building 9 is fixedly positioned on the guide rail 1, it can swing adaptively relative to the lifting connecting rod 4, gripper 60 and guide rail 1 below it, which plays a certain role in buffering. It prevents the lifting screw 3, lifting connecting rod 4, clamping plate, gripper 60 and guide rail 1 from being directly subjected to bending and shearing forces, thus avoiding deformation and breakage. This further improves the reliability and safety of the factory building and extends the service life of the guide rail 1 and gripper 60.
[0023] The lifting handwheel 2 is used to drive the lifting screw 3 to move up and down. Both the lifting handwheel 2 and the adjusting handwheel 70 can be common circular handwheels available on the market. Generally, the axis of the lifting handwheel 2 is perpendicular to the top surface of the support beam 91, and the adjusting handwheel 70 is coaxial with the adjusting screw 7. The lifting handwheel 2 and the support beam 91 should not have relative displacement in the vertical direction. The lifting handwheel 2 can be axially limited on the support beam 91 by an axial limiting block, or other methods can be used. Specifically, a bearing seat 21 is fixedly provided on the top of the support beam 91. The bearing seat 21 has bearing mounting holes arranged vertically, and a rotating bearing 22 is provided inside the bearing mounting holes. The outer ring of the rotating bearing 22 is interference-fitted with the bearing mounting holes. A rotating bushing 23 is interference-fitted to the inner side of the inner ring of the rotating bearing 22, and the lifting handwheel 2 is fixedly connected to the top of the rotating bushing 23. Using a rotating bearing to achieve the rotating connection between the lifting handwheel 2 and the support beam 91 allows the lifting handwheel 2 to rotate more effortlessly, saving manpower. A rotating bushing 23 is fitted onto the outside of the lifting screw 3. The two can be threaded together or spaced apart to ensure that the lifting screw 3 can move up and down with the rotation of the adjusting handwheel 70. The bearing seat 21 can be fixed to the support beam 91 by welding or bolting. The support beam 91 has a through hole running vertically through it, within which the lifting screw 3 can move up and down.
[0024] The lifting screw 3 is used to drive the lifting connecting rod 4 to move up and down within the guide control 51 under the drive of the lifting handwheel 2. Preferably, the upper end of the lifting screw 3 is provided with an upper limit block 30, which protrudes horizontally from the outer side wall of the lifting screw 3. This prevents the lifting screw 3 from moving too far downward and disengaging from the lifting handwheel 2, thus limiting the lifting screw 3 in the up and down direction. The upper limit block 30 can be installed on the top of the lifting screw 3 by welding or bolting.
[0025] The lifting linkage 4 is used to drive the first clamping plate 61, the second clamping plate 62, and the gripper 60 to move up and down synchronously. The lifting linkage 4 and the lifting screw 3 can be hinged together via a universal ball joint, or via one or more pivots, or via other hinged connections for gripping and transfer. Specifically, the following embodiments are also included: Example 1, such as Figure 1-3As shown, it also includes a first connecting rod 31, a second connecting rod 32, a first pivot 81, a second pivot 82, and a third pivot 83. The upper end of the first connecting rod 31 is pivotally connected to the lower end of the lifting screw 3 via the first pivot 81, the lower end of the first connecting rod 31 is pivotally connected to the upper end of the second connecting rod 32 via the second pivot 82, and the lower end of the second connecting rod 32 is pivotally connected to the lifting connecting rod 4 via the third pivot 83. The axes of the first pivot 81 and the third pivot 83 are both arranged along a first horizontal direction, and the axis of the second pivot 82 is arranged along a second horizontal direction perpendicular to the first horizontal direction. By setting multiple pivotally connected rods, the lifting connecting rod 4 and the lifting screw 3 are pivotally connected around two different horizontal axes, improving the hinge flexibility of the lifting connecting rod 4 and the lifting screw 3.
[0026] Example 2, as follows Figure 6 As shown, it also includes a first connecting rod 31, a second connecting rod 32, a first adapter 33, a second adapter 34, a first rotating shaft 84, a second rotating shaft 85, a third rotating shaft 86, a fourth rotating shaft 87, and a third pivot 83. The axes of the first rotating shaft 84, the second rotating shaft 85, and the third pivot 83 are all arranged along a first horizontal direction, and the axes of the third rotating shaft 86 and the fourth rotating shaft 87 are all arranged along a second horizontal direction perpendicular to the first horizontal direction. The first adapter 33 has a first strip-shaped through hole, and the second adapter 34 has a second strip-shaped through hole. The lower end of the lifting screw 3 is hinged to the upper end of the first adapter 33 through the first rotating shaft 84. The lower end of the first adapter 33 and the... The upper end of the first connecting rod 31 is hinged to the second rotating shaft 85; both the first rotating shaft 84 and the second rotating shaft 85 pass through the first strip-shaped through hole and slide in cooperation with the first adapter 33 along the length direction of the first strip-shaped through hole; the lower end of the first connecting rod 31 is hinged to the upper end of the second adapter 34 through the third rotating shaft 86, and the lower end of the second adapter 34 is hinged to the upper end of the second connecting rod 32 through the fourth rotating shaft 87; both the third rotating shaft 86 and the fourth rotating shaft 87 pass through the second strip-shaped through hole and slide in cooperation with the second adapter 34 along the length direction of the second strip-shaped through hole; the lower end of the second connecting rod 32 is pivotally connected to the lifting connecting rod 4 through the third pivot 83. In Embodiment 2, the first adapter 33 swings relative to the lifting screw 3 around the first pivot 84. Both the first adapter 33 and the first connecting rod 31 can swing around the second pivot 85. Both the first connecting rod 31 and the second adapter 34 can swing around the third pivot 86. The lower end of the second adapter 34 and the second connecting rod 32 can both swing around the fourth pivot 87. Compared to Embodiment 1, Embodiment 2 offers better flexibility, stronger buffering capacity, reduced assembly precision, and makes it easier to connect the upper end of the first connecting rod 31 to the lifting screw 3 and assemble the lower end of the first connecting rod 31 and the second connecting rod 32.
[0027] In the second embodiment described above, the first adapter 33 and the second adapter 34 are generally both plate parts, and two of each are provided. The two first adapters 33 are distributed along a first horizontal direction and located on both sides of the first adapter 33, and the two second adapters are distributed along a second horizontal direction and located on both sides of the second adapter 34. To ensure the reliability of the hinged rod connection, axial limiting components are provided at both ends of the pivot and the shaft to prevent axial displacement of the pivot and the shaft from disengaging from the rod. The axial limiting components on the pivot and the shaft are generally cotter pins, which are simple in mechanism and easy to assemble and disassemble.
[0028] If the pivot or rotating shaft is directly connected to the lifting link 4 in the above connection structure, holes need to be drilled in the lifting link 4, which would undoubtedly affect the overall strength of the lifting link 4, making it susceptible to bending deformation and breakage. Preferably, it also includes an upward-facing U-shaped sleeve 41, which is fitted onto the outside of the lifting link 4; the second link 32 and the U-shaped sleeve 41 are pivotally connected by the third pivot 83. The U-shaped sleeve 41 is used to lift the lifting link 4 upward, realizing the connection between the lifting link 4 and the second link 32, avoiding drilling holes in the lifting link 4 and affecting its strength.
[0029] As a further preferred embodiment, both ends of the lifting link 4 are provided with axial limiting ring plates 42. The outer edge of the axial limiting ring plate 42 protrudes from the outer side wall of the lifting link 4. The axial limiting ring plates 42 at both ends of the lifting link 4 are located on both sides of the guide seat 5 and are spaced apart from the guide seat 5. The two axial limiting ring plates 42 are used to axially limit the lifting link 4 and prevent the lifting link 4 from coming out of the guide bar hole 51.

[0033] A fixed structure for a large mobile factory includes a factory building 9 and a guide rail 1 fixedly mounted on the ground. The guide rail 1 is parallel to the horizontal plane and has guide grooves 11 on both sides in the horizontal direction. The length direction of the guide grooves 11 is the same as the length direction of the guide rail 1. The bottom of the factory building 9 is provided with multiple support beams 91, which are parallel to the guide rail. Multiple sets of fastening devices for the large mobile factory are provided on the support beams 91, and the multiple sets of fastening devices are spaced apart along the length direction of the guide rail 1. The guide rail 1 is located between the first clamping plate 61 and the... Between the second clamping plates 62, the claws 60 on the first clamping plate 61 and the second clamping plate 62 are respectively located in the guide grooves 11 on both sides of the guide rail 1; when the large mobile factory is fixedly installed on the guide rail 1, the first clamping plate 61 and the second clamping plate 62 respectively abut against the two side walls of the guide rail 1 in the horizontal direction, the claws 60 on the first clamping plate 61 and the claws 60 on the second clamping plate 62 respectively abut against the bottom wall of the guide groove 11, and the top surface of the claws 60 abuts against the upper side wall of the guide groove 11. The first clamping plate 61 and the second clamping plate 62 cooperate with each other, and the claws 60 on the first clamping plate 61 and the second clamping plate 62 cooperate with each other to clamp and fasten the entire mobile factory 9 to the guide rail 1, thereby positioning the entire mobile factory 9 in the horizontal direction perpendicular to the horizontal guide rail. The top surface of the claws 60 abuts against the upper side wall of the guide groove 11 of the guide rail 1, thereby achieving the vertical positioning of the entire mobile factory 9 and further increasing the fastening contact area between the first clamping plate 61, the second clamping plate 62, the claws 60 and the guide rail 1, thus improving the stability of the mobile factory. Generally, a single support beam 91 is equipped with two sets of large mobile factory fastening devices, and a single factory 9 is equipped with two sets of support beams 91, that is, a single factory 9 is equipped with four sets of large mobile factory fastening devices at the bottom.
[0034] The mobile positioning of the factory building in the fixed structure of a large mobile factory building refers to moving the factory building 9 from its initial position on the guide rail 1 to a target position, and locking it in place at the target position on the guide rail 1. The factory building 9 is initially locked in place at its initial position on the guide rail 1. The above-mentioned mobile positioning method for the factory building includes the following steps: S1. Rotating the lifting handwheel 2 causes the lifting screw 3 to move downward in a straight line, while simultaneously driving the lifting connecting rod 4 to move downward along the length direction of the guide bar hole 51. The lifting connecting rod 4 drives the first clamping plate 61 and the second clamping plate 62 and the clamping claws 60 on them to move downward synchronously, so that the top surface of the clamping claws 60 and the upper side wall of the guide groove 11 on the guide rail 1 are arranged at intervals. S2. Rotate the adjusting handwheel 70 to drive the adjusting screw 7 to rotate. The adjusting screw 7 simultaneously drives the first clamping plate 61 and the clamping jaws 60 thereon to move away from the second clamping plate 62. The second clamping plate 62 and the clamping jaws 60 thereon move away from the first clamping plate 61 so that the clamping jaws 60 and the guide groove 11 are completely spaced apart. S4. Pull the factory building 9 to the target position along the length of the guide rail 1; S5. Rotate the adjusting handwheel 70 in the opposite direction to make the adjusting handwheel 70 drive the adjusting screw 7 to rotate. The adjusting screw 7 simultaneously drives the first clamping plate 61 and the second clamping plate 62 and the jaws 60 on them to move towards each other until the clamping surfaces of the jaws 60 on the first clamping plate 61 and the second clamping plate 62 slide into contact with the groove wall of the guide groove 11. S6. Rotate the lifting handwheel 2 in the opposite direction to make the lifting screw 3 move upward in a straight line, while pulling the lifting connecting rod 4 upward along the length direction of the guide bar hole 51. The lifting connecting rod 4 simultaneously pulls the first clamping plate 61 and the second clamping plate 62 and the clamping claw 60 on them upward until the top surface of the clamping claw 60 abuts against the upper side wall of the guide groove 11 on the guide rail 1. S7. Repeat step S5 to clamp the guide rail 1 along the horizontal direction perpendicular to the guide rail 1 on the two opposite faces of the jaws 60 on the first clamping plate 61 and the second clamping plate 62.
[0035] Steps S1 and S2 can be performed simultaneously, or step S2 can be performed first and then step S1. In step S1, the rotation direction of the lifting handwheel 2 is opposite to that in step S6; in step S2, the rotation direction of the adjusting handwheel 70 is opposite to that in step S5; and in step S7, the rotation direction of the lifting handwheel 70 is the same as that in step S5. The rotation of the lifting handwheel 2 and the adjusting handwheel 70 can be done manually or driven by electric or hydraulic actuators. Throughout these steps, the gripper 60 should always be kept within the guide groove 11. This method allows for more convenient and faster transfer and securing of large mobile factory buildings, increases the securing contact area between the factory building 9 and the guide rail 1, and improves the reliability and safety of erecting large mobile factory buildings in windy areas.
