Description
Technical Field
[0001] This utility model relates to the field of gantry crane technology, and in particular to a small component-assisted installation gantry crane. Background Technology
[0002] Shipbuilding refers to the systematic industrial process of transforming raw materials (such as steel and composite materials) into ship products that meet specific functional requirements through a series of engineering activities including design, material processing, component assembly, and system integration. It is the core link of the shipbuilding industry, and shipbuilding is generally divided into five major stages: design, material preparation, processing and manufacturing, assembly and integration, and testing and delivery. Steel structure construction mainly involves two stages: factory processing (cutting, welding, surface treatment) and on-site installation (assembly, hoisting). The efficient and precise movement of small components (such as bolts, washers, stiffening plates, small steel profiles, welding materials, outfitting parts, etc.) is a key link in ensuring construction progress and quality. A gantry crane is essentially a "gate"-shaped frame lifting device, an industrial equipment used for vertical or horizontal handling and hoisting of heavy objects, widely used in factories, warehouses, construction sites, and other scenarios.
[0003] In steel structure and shipbuilding, numerous small components need to be moved to designated locations for installation. Using cranes for this purpose is not only inefficient but also costly. Furthermore, narrow passageways in workshops and docks prevent access to certain equipment, and cranes often cannot reach confined areas or cabin interiors. Conventional gantry cranes are fixed frame structures; when not in use, they occupy a large area, and if the exit dimensions are small, they may be unable to be moved in or out.
[0004] Therefore, we propose a small component to assist in the installation of the gantry frame, in order to solve the problems mentioned above. Utility Model Content
[0005] Technical problems to be solved: To address the shortcomings of existing technologies, this utility model provides a small-component auxiliary installation gantry frame with a rotatable and foldable support leg structure. The folded gantry frame is compact, small in size, easy to store and transport, and can be moved flexibly in various confined spaces. The support height of the support leg structure can be adjusted according to actual usage needs, thereby adjusting the height of the gantry frame and solving the technical problems mentioned in the background art.
[0006] Technical solution: To achieve the above objectives, this utility model provides the following technical solution: A small-component auxiliary installation gantry frame includes two sets of support leg structures, with a crossbeam between the two sets of support leg structures. Lifting lugs are fixedly mounted on the crossbeam, and the lugs can be welded to the crossbeam or bolted to it. The rated load of the lifting lugs is calculated based on the lifting weight to ensure that the strength of the lugs is greater than 1.5 times the working load. Each support leg structure includes a base frame, on which a fixed plate is fixedly mounted. The fixed plate is connected to an adjusting plate, and the adjusting plate and the fixed plate are fixedly connected by locking bolts. A telescopic column is fixedly mounted on the adjusting plate, and the telescopic column includes a fixed... The system includes a column and a telescopic column. The top of the telescopic column is fixedly equipped with a second connecting seat. The second connecting seat is rotatably connected to a sliding seat via a rotating shaft. The rated load of the rotating shaft is calculated based on the lifting weight to ensure that the strength of the rotating shaft can meet the lifting requirements of the small components. The sliding seat is slidably connected to the crossbeam. The lifting lug is the connection position of the gantry frame. The lifting lug can be connected to a manual or electric hoist. The manual or electric hoist is installed on the crossbeam of the gantry frame to achieve direct lifting of the small components. After lifting, the workers push the gantry frame to move, and the gantry frame drives the small components to move synchronously to the designated position for installation.
[0007] In one possible implementation, the fixed column has a first through hole, and the telescopic column has multiple sets of second through holes. The multiple sets of second through holes are evenly distributed along the straight direction of the telescopic column. The diameters of the first and second through holes are the same, and the diameters of the first and second through holes are adapted to the pin. The diameter of the pin is slightly larger than the diameters of the first and second through holes. An external force is applied to press the pin into place. After the pin is installed in place, the pin fits tightly against the hole wall, and the friction can resist the vibration of the working load.
[0008] In one possible implementation, the lower end of the telescopic column is embedded in the fixed column and slidably connected to it. The telescopic column and the fixed column are fixed by a pin. The pin passes through a first through hole in the fixed column and a second through hole in the telescopic column. After the pin is pulled out, a certain external force is applied to the telescopic column, which can drive the telescopic column to slide axially relative to the fixed column. The total length of the telescopic column is adjusted by adjusting the extension length of the telescopic column relative to the fixed column. After the adjustment is completed, the pin passes through the first through hole in the fixed column and the second through hole in the telescopic column to fix the telescopic column to the fixed column.
[0009] In one possible implementation, two sets of diagonal supports are welded and fixed on the adjustment plate. The two sets of diagonal supports are located on both sides of the telescopic column. The diagonal supports are welded and fixedly connected to the fixed column. The diagonal supports, the adjustment plate and the fixed column form a triangular structure. The overall rigidity and anti-lateral displacement ability of the gantry are enhanced by the principle of triangle stability, so as to ensure the safety and stability of the hoisting operation.
[0010] In one possible implementation, a first connecting seat is welded and fixed to both sides of the upper surface of the fixing plate, and a connecting block is welded and fixed to both sides of the lower surface of the adjusting plate.
[0011] In one possible implementation, both the first connecting seat and the connecting block have through holes. The locking bolt passes through the through holes of the first connecting seat and the connecting block and is locked by a nut. When the locking bolt is loosened, the fastening between the connecting block and the first connecting seat is released. At this time, the connecting block can rotate relative to the first connecting seat, and the rotatable folding support leg structure can be achieved. During the folding process, the slide deflects relative to the second connecting seat and slides along the straight direction of the crossbeam. The folded gantry structure is compact, small in size, retractable, and easy to transport. It can move flexibly in various narrow spaces and can pass through narrow passages, such as workshop doors, stairwells, and cabin doors, to enter other gantry structures and areas that cranes cannot reach, making it convenient to use.
[0012] In one possible implementation, the crossbeam is configured as an I-beam structure, with the flanges of the I-beam bearing the main stress and the web bearing the shear stress. The upper flange of the I-beam crossbeam can be directly used as the track support surface, or the track can be fixed by a pressure plate, making it compatible with various electric hoists.
[0013] In one possible implementation, the slide includes a groove, the side of the crossbeam passes through the groove of the slide and is slidably connected to the groove, and limit plates are welded and fixed at both ends of the crossbeam.
[0014] In one possible implementation, a connector is welded to one end of the pin, and a hole is provided on the connector. After long-term use, the pin may need to be disassembled due to wear or corrosion. The hole at one end can provide a force point for the disassembly tool and avoid damage caused by directly hitting the pin body.
[0015] In one possible implementation, a fixed wheel is installed on one side of the lower end face of the base frame, and a swivel wheel is installed on the other side of the lower end face of the base frame. The two sets of swivel wheels and the two sets of fixed wheels are combined to form the roller structure of the gantry frame. The swivel wheels are responsible for steering and small-range movement, and can rotate freely 360 degrees through a rotation pivot to adapt to the steering needs of narrow passages and complex paths. The fixed wheels are responsible for bearing and stability, and provide linear support through rigid wheel axles to prevent the gantry frame from tipping over due to the shift of the center of gravity.
[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. The present invention features a rotatable folding support leg structure. During the folding process, the slide seat deflects relative to the second connecting seat and slides along the straight direction of the crossbeam. The folded gantry structure is compact and small in size, easy to store and transport, and can move flexibly in various narrow spaces. It can pass through narrow passages, such as workshop doors, stairwells, and cabin doors, to enter areas that other gantry frames and cranes cannot reach, making it convenient to use.
[0017] 2. This utility model adjusts the total length of the telescopic column by adjusting the extension length of the telescopic column relative to the fixed column, thereby adjusting the support height of the outrigger structure. After adjustment, a pin is used to pass through the first through hole of the fixed column and the second through hole of the telescopic column to achieve fastening. The adjustment is convenient, and the support height of the outrigger structure can be adjusted according to actual usage needs. The height of the gantry can be adjusted by adjusting the support height of the outrigger structure. When the length of the small component is long, the height of the gantry can be increased accordingly, and when the length of the small component is short, the height of the gantry can be decreased accordingly, thereby improving the flexibility of the gantry during use.
[0018] 3. The two sets of omnidirectional wheels and two sets of fixed wheels of this utility model are combined to form the roller structure of the gantry frame. The omnidirectional wheels are responsible for steering and small-range movement, and can rotate freely 360 degrees through the rotation pivot to adapt to the steering needs of narrow passages and complex paths. The fixed wheels are responsible for load bearing and stability, and provide straight support through rigid wheel axles to prevent the gantry frame from tipping over due to the shift of the center of gravity. The functional division of the front and rear wheels realizes flexible steering and stable load bearing, making the movement of the gantry frame convenient. Attached Figure Description

[0022] This application provides a small component-assisted installation gantry frame with a rotatable and foldable support leg structure. The folded gantry frame structure is compact, small in size, retractable, easy to transport, and can be moved flexibly in various confined spaces. The support height of the support leg structure can be adjusted according to actual usage needs, thereby adjusting the height of the gantry frame, thus solving the technical problems mentioned in the background art.
[0023] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example 1: Please see Figure 1-10This utility model provides a technical solution: a small component-assisted installation gantry frame, including two sets of support leg structures 1, with a crossbeam 2 between the two sets of support leg structures 1. One set of support leg structures 1 is located on one side below the crossbeam 2, and the other set of support leg structures 1 is located on the other side below the crossbeam 2. The two sets of support leg structures 1 provide stable support for the crossbeam 2. Lifting lugs 22 are fixedly installed on the crossbeam 2. The lifting lugs 22 can be welded to the crossbeam 2 or bolted. The bolted connection fixes the lifting lugs 22 to the crossbeam 2 of the gantry frame with pre-tightening force, relying on the friction of the threaded pair or mechanical locking to transfer the load. It can be repeatedly disassembled and is easy to maintain. The welded connection is firm and has good structural integrity. The function of the lifting lugs 22 is to transfer the lifting load to the main structure of the gantry frame, ensuring that the load is evenly distributed and avoiding local stress concentration. The rated load of the lifting lugs 22 is calculated according to the lifting weight to ensure that the strength of the lifting lugs 22 is greater than 1.5 times the working load. Leg structure 1 includes a base frame 11, on which a fixed plate 12 is fixedly mounted. The base frame 11 and the fixed plate 12 are welded and fixedly connected. The fixed plate 12 is connected to an adjusting plate 13, and the adjusting plate 13 and the fixed plate 12 are fixedly connected by locking bolts 14. A telescopic column 15 is fixedly mounted on the adjusting plate 13. The telescopic column 15 includes a fixed column 151 and a telescopic column 152. The adjusting plate 13 and the fixed column 151 of the telescopic column 15 are welded and fixedly connected. A second connecting seat 154 is fixedly mounted at the top of the telescopic column 152. The telescopic column 152 and the second connecting seat 154 are welded and fixedly connected. The second connecting seat 154 is rotatably connected to a slide 155 through a rotating shaft. The rated load of the rotating shaft is calculated according to the lifting weight to ensure that the strength of the rotating shaft can meet the lifting requirements of small components. The slide 155 is slidably connected to the crossbeam 2. The sliding groove of the slide 155 is adapted to the structure of the crossbeam 2, and the slide 155 can slide along the straight direction of the crossbeam 2.
[0024] The lifting lug 22 is the connection point of the gantry frame. The lifting lug 22 can be connected to a manual or electric hoist. The electric hoist drives the chain or wire rope through the motor to realize the vertical lifting and horizontal movement of the object. The manual hoist is driven by pulling the chain or turning the handle manually, which is suitable for scenarios without power. The manual or electric hoist is installed on the crossbeam 2 of the gantry frame to realize the direct hoisting of small components. After hoisting, the gantry frame is pushed to move, and the gantry frame drives the small components to move synchronously, moving the small components to the designated position for installation.
[0025] In some examples, the fixed column 151 has a first through hole 1511, and the telescopic column 152 has multiple sets of second through holes 1521. The multiple sets of second through holes 1521 are evenly distributed along the straight direction of the telescopic column 152. The diameters of the first through holes 1511 and the second through holes 1521 are the same, and the diameters of the first through holes 1511 and the second through holes 1521 are adapted to the pin 153. When the telescopic column 152 and the fixed column 151 are fixedly connected, the first through hole 1511 of the fixed column 151 is aligned with a certain second through hole 1521 of the telescopic column 152 to ensure that the pin 153 can be inserted just right. The total length of the telescopic column 15 is adjusted by adjusting the position of the second through hole 1521 aligned with the first through hole 1511. Both the fixed column 151 and the telescopic column 152 are made of square steel pipes with regular cross-sectional shapes and balanced load-bearing capacity.
[0026] In some examples, the lower end of the telescopic column 152 is embedded in the fixed column 151 and slidably connected to the fixed column 151. Under the drive of external force, the telescopic column 152 can slide along the fixed column 151. The extension length of the telescopic column 152 relative to the fixed column 151 is adjustable. The telescopic column 152 and the fixed column 151 are fixed by a pin 153. The pin 153 passes through the first through hole 1511 of the fixed column 151 and the second through hole 1521 of the telescopic column 152. The diameter of the pin 153 is slightly larger than the diameter of the first through hole 1511 and the second through hole 1521. When an external force is applied to press the pin 153 in place, the pin 153 fits tightly against the hole wall. The friction can resist the vibration of the working load, resulting in high connection reliability, strong anti-loosening ability, and the pin 153 is not easy to fall off.
[0027] After pulling out the pin 153, a certain external force is applied to the telescopic column 152, which can drive the telescopic column 152 to slide axially relative to the fixed column 151. By adjusting the extension length of the telescopic column 152 relative to the fixed column 151, the total length of the telescopic column 15 is adjusted, thereby adjusting the support height of the support leg structure 1. After the adjustment is completed, the pin 153 is used to pass through the first through hole 1511 of the fixed column 151 and the second through hole 1521 of the telescopic column 152 to fix the telescopic column 152 and the fixed column 151, so that the telescopic column 15 can be stably supported.
[0028] The support height of the outrigger structure 1 can be adjusted according to actual usage needs. The height of the gantry can be adjusted by adjusting the support height of the outrigger structure 1. When the length of the small component is long, the height of the gantry can be increased accordingly. When the length of the small component is short, the height of the gantry can be decreased accordingly, thereby improving the flexibility of the gantry during use and meeting the hoisting needs of different small components.
[0029] In some examples, two sets of diagonal supports 16 are welded and fixed on the adjusting plate 13. The two sets of diagonal supports 16 are located on both sides of the telescopic column 15. The diagonal supports 16 are welded and fixedly connected to the fixed column 151. One end of the diagonal support 16 is welded and fixedly connected to the telescopic column 15, and the other end of the diagonal support 16 is welded and fixedly connected to the adjusting plate 13. The diagonal support 16, the adjusting plate 13 and the fixed column 151 form a triangular structure. The rigidity of the outrigger structure 1 is enhanced by the principle of triangular stability, thereby enhancing the overall rigidity and anti-lateral displacement ability of the gantry frame and ensuring the safety and stability of the hoisting operation.
[0030] In some examples, the upper end face of the fixed plate 12 is welded and fixed to both sides of the first connecting seat 121, and the lower end face of the adjusting plate 13 is welded and fixed to both sides of the connecting block 131. The first connecting seat 121 includes a connecting position, and the connecting block 131 is located in the connecting position of the first connecting seat 121. The two are connected by a locking bolt 14.
[0031] In some examples, both the first connecting seat 121 and the connecting block 131 have through holes, and the locking bolt 14 passes through the through holes of the first connecting seat 121 and the connecting block 131 and is locked by a nut.
[0032] like Figure 6 and Figure 7 As shown, the connecting block 131 of the adjusting plate 13 is fixedly connected to the first connecting seat 121 of the fixed plate 12 by a locking bolt 14. When the locking bolt 14 is loosened, the fastening between the connecting block 131 and the first connecting seat 121 is released, and the connecting block 131 can rotate relative to the first connecting seat 121. That is, the adjusting plate 13 can rotate relative to the fixed plate 12. Figure 9 As shown, the rotatable folding support leg structure 1 is used. Both sets of support leg structures 1 are folded in the same way. During the folding process, the slide 155 deflects relative to the second connecting seat 154. The slide 155 slides along the straight direction of the crossbeam 2. After the gantry is folded into place, it presents the following shape: Figure 9 As shown, the folded gantry has a compact structure, small size, is easy to store and transport, and can be moved flexibly in various narrow spaces. It can pass through narrow passages, such as workshop doors, stairwells, and cabin doors, to enter areas that other gantry and cranes cannot reach, making it convenient to use.
[0033] When the gantry crane is unfolded for use, such as Figure 8 As shown, the outrigger structure 1 is rotated and unfolded. Both sets of outrigger structures 1 are unfolded in the same way. During the unfolding process, the slide 155 deflects relative to the second connecting seat 154. The slide 155 slides along the straight direction of the crossbeam 2. After the gantry is unfolded into place, the locking bolt 14 at the connection between the fixing plate 12 and the adjusting plate 13 is tightened with a nut to achieve fastening. The unfolded gantry can provide stable support.
[0034] In some examples, the crossbeam 2 is set as an I-beam structure, with the flanges of the I-beam bearing the main stress and the web bearing the shear stress. The upper flange of the I-beam crossbeam 2 can be directly used as the track support surface, or the track can be fixed by a pressure plate, making it suitable for use with various electric hoists.
[0035] In some examples, the slide 155 includes a groove, the side of the crossbeam 2 passes through the groove of the slide 155 and is slidably connected to the groove, and both ends of the crossbeam 2 are welded and fixed with limit plates 21 to limit the slide 155 of the support leg structure 1 and prevent the slide 155 from sliding off.
[0036] In some examples, a connector 1531 is welded to one end of the pin 153. The connector 1531 has a hole 1532. After long-term use, the pin 153 may need to be disassembled due to wear or corrosion. The hole 1532 at one end can provide a force point for the disassembly tool and avoid damage caused by directly hitting the pin 153 body.
[0037] By adopting the above technical solution: The rotatable folding support leg structure 1, during the folding process, the slide 155 deflects relative to the second connecting seat 154 and slides along the straight direction of the crossbeam 2. The folded gantry structure is compact and small in size, easy to store and transport, and can move flexibly in various narrow spaces. It can pass through narrow passages, such as workshop doors, stairwells, and cabin doors, and enter areas that other gantry structures and cranes cannot reach, making it convenient to use.
[0038] The total length of the telescopic column 15 is adjusted by adjusting the extension length of the telescopic column 152 relative to the fixed column 151, thereby adjusting the support height of the support leg structure 1. After adjustment, the pin 153 is passed through the first through hole 1511 of the fixed column 151 and the second through hole 1521 of the telescopic column 152 to achieve fastening. The adjustment is convenient, and the support height of the support leg structure 1 can be adjusted according to actual usage requirements. The height of the gantry is adjusted by adjusting the support height of the support leg structure 1. When the length of the small component is long, the height of the gantry is increased accordingly, and when the length of the small component is short, the height of the gantry is decreased accordingly, thereby improving the flexibility of the gantry during use.
[0039] Example 2: Based on Example 1, this example describes the specific structure of the base frame 11 in a small component-assisted installation gantry. A fixed wheel 17 is installed on one side of the lower end face of the base frame 11, and a caster wheel 18 is installed on the other side of the lower end face of the base frame 11. The wheel body of the caster wheel 18 is connected to the base frame 11 of the gantry through a rotating pivot, and can rotate freely 360 degrees, supporting movement in any direction. The wheel body of the fixed wheel 17 is fixed to the base frame 11 of the gantry through a rigid shaft, and can only roll along the wheel axle direction, supporting only linear movement.
[0040] Two sets of omnidirectional wheels 18 and two sets of fixed wheels 17 are combined to form the roller structure of the gantry. The omnidirectional wheels 18 are responsible for steering and small-range movement, and can rotate freely 360 degrees through the rotation pivot to adapt to the steering needs of narrow passages and complex paths. The fixed wheels 17 are responsible for load bearing and stability, and provide straight support through rigid wheel axles to prevent the gantry from tipping over due to the shift of the center of gravity. The division of functions between the front and rear wheels realizes flexible steering and stable load bearing, making the movement of the gantry convenient.
[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
