Description

Technical Field

[0001] The present invention relates to the field of steel structure frame handling devices, especially large steel structure frames with modular splicing. Background Art

[0002] A large steel structure frame with modular splicing is a building structure form that is quickly assembled on-site through prefabricated modular components. Its advantage is that the large steel structure frame with modular splicing is quickly assembled on-site through prefabricated modular components, reducing on-site construction time and costs, and improving building quality and design flexibility. Compared with traditional on-site construction, modular buildings can provide more consistent building quality, shorten the construction period, and reduce environmental interference.

[0003] A large steel structure frame with modular splicing facilitates the assembly of steel structures, enabling the steel structures to be assembled modularly. When splicing steel structures, it is necessary to carry the required parts or steel members to facilitate the assembly and splicing of the parts. However, existing handling devices can only fix steel members of specified sizes. For steel members of different sizes, different fixing devices need to be replaced to fix the steel members. Therefore, a large steel structure frame with modular splicing is required to provide an adjustable handling device. Summary of the Invention

[0004] The purpose of the present invention is to provide a large steel structure frame with modular splicing to overcome the defect that the handling device is not convenient for adjusting and fixing sizes.

[0005] The technical solution to achieve the above purpose is: a large steel structure frame with modular splicing, including a moving mechanism, a connecting mechanism is installed on the moving mechanism, a driving mechanism is installed on the connecting mechanism, a positioning mechanism is installed on the driving mechanism, and a fixing mechanism is installed on the connecting mechanism.

[0006] Preferably, the moving mechanism includes a bracket, moving wheels, and a hydraulic cylinder. The bottom end of the bracket is connected with the moving wheels, and the top end of the bracket is connected with the hydraulic cylinder.

[0007] Preferably, the output end of the hydraulic cylinder penetrates through the top side wall of the bracket. The shape of the bracket is U-shaped, and the moving wheels are made of electric wheels.

[0008] Preferably, the connecting mechanism includes a top plate, side plates, first guide rods, and a bottom groove. The top end of the top plate is connected with the output end of the hydraulic cylinder. Two symmetrically distributed side plates are connected to both side walls of the top plate. The side walls of the side plates are connected with the first guide rods. A bottom groove is opened at the bottom end of the top plate, and the bottom groove is symmetrically distributed about the axis of symmetry of the top plate.

[0009] Preferably, the driving mechanism includes a connecting block, a second guide rod, a slider, a gear, a rack and a rotating motor. Two symmetrically distributed connecting blocks are connected to the inner side wall of the bottom groove. The side wall of the connecting block is connected with a second guide rod. The rotating motor is connected to the inner top end of the bottom groove. The output end of the rotating motor is connected with a gear. The top end of the rack is connected with a plurality of sliders. The side wall of the slider is slidably connected with the second guide rod. The two racks are symmetrically distributed about the gear. The side wall of the rack is meshed with the gear. The rotating gear is located at the center of the bottom groove.

[0010] Preferably, the positioning mechanism includes a connecting plate, a push rod motor and a positioning plate. One end of the rack is connected with a connecting plate. The side wall of the connecting plate is connected with a push rod motor. The output end of the push rod motor is connected with a positioning plate. The push rod motor and the positioning plate are both located on the axis of symmetry of the bottom groove.

[0011] Preferably, the fixing mechanism includes a support plate, a bottom plate, a support block, a connecting shaft, a round shaft, a limiting screw, a pressing plate, a pressing screw and a round hole. The side wall of the first guide rod is movably connected with a plurality of support plates. The top end of the bottom plate is connected with a support block. The side wall of the support block is connected with a connecting shaft. The side wall of the connecting shaft is rotatably connected with the bottom end of the support plate. Two symmetrically distributed round shafts are connected to the inner side wall of the bottom plate. The side wall of the round shaft is slidably connected with a pressing plate. The side wall of the pressing plate is threadedly connected with a pressing screw. A round hole is opened at the bottom end of the bottom plate. The side wall of the bottom plate is threadedly connected with a limiting screw.

[0012] Preferably, the bottom plate is U-shaped. The length of the top end of the bottom plate is less than the length of the bottom end of the bottom plate. One end of the limiting screw is connected with a rubber pad.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1) Rotate the support plate to make the support plate expand outwards. The support plate drives the connecting shaft to rotate outwards. The connecting shaft drives the bottom plate to move outwards, so that the two symmetrically distributed bottom plates are expanded, thereby realizing the adjustment of the distance between the bottom plates to adapt to the length of the steel member. The bottom plate can be rotatably connected with the support plate through the connecting shaft to adjust the inclination angle of the bottom plate to adapt to the inclined surface at the bottom end of the steel member. At this time, the bottom plate is clamped onto the surface of the steel member, so that the inner bottom end of the bottom plate is in contact with the bottom end of the steel member. Then, press down the pressing plate. The pressing plate is in contact with the top end of the steel member, and the pressing screw is screwed into the round hole to press the pressing plate, thereby realizing the effect of clamping the steel member between the bottom plate and the pressing plate, achieving the effect of being able to fix steel members of various lengths and with inclined surfaces at the bottom end.

[0015] 2) Start the rotating motor. The rotating motor drives the gear to rotate, and the gear drives the two racks to move in the outer end directions on both sides respectively. The racks drive the sliders to move along the second guide rod, causing the racks to drive the connecting plate to move outwards. The connecting plate drives the push rod motor to move, and the push rod motor drives the positioning plate to move horizontally. Then, drive the push rod motor again to make the positioning plate move downwards, so that the two positioning plates are respectively located on the outer sides of both sides of the steel member. At this time, mark at the center of both sides of the steel member. Then, the bracket moves, causing the top plate to move, and the top plate drives the entire driving mechanism to move, thereby causing the positioning plate to move until the positioning plate moves to be in contact with the center of the side wall of the steel member. Then, pull the positioning plate upwards, and at the same time, push the top plate downwards, causing the top plate to drive the driving mechanism to move downwards, and the driving mechanism drives the positioning mechanism to move downwards, so that the top plate is at the symmetry axis of the steel member, avoiding uneven force on the fixing mechanisms on both sides.

[0016] 3) Start the moving wheels. The moving wheels can drive the bracket to move, and the bracket drives the hydraulic cylinder to move. Since the top plate is connected to the hydraulic cylinder, the top plate and the parts connected to the top plate move synchronously. That is, the driving mechanism, the positioning mechanism, and the fixing mechanism will also move horizontally accordingly, making the entire connecting mechanism move horizontally synchronously with the hydraulic cylinder, achieving the effect of convenient movement.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

The bottom end of the bracket 101 is connected with the moving wheel 102, the top end of the bracket 101 is connected with the hydraulic cylinder 103, the output end of the hydraulic cylinder 103 penetrates through the top side wall of the bracket 101, the shape of the bracket 101 is U-shaped, the moving wheel 102 is made of an electric wheel, the connecting mechanism 2 includes a top plate 201, side plates 202, a first guide rod 203 and a bottom groove 204. The top end of the top plate 201 is connected with the output end of the hydraulic cylinder 103, two symmetrically distributed side plates 202 are connected to both side walls of the top plate 201, the side wall of the side plate 202 is connected with the first guide rod 203, a bottom groove 204 is opened at the bottom end of the top plate 201, and the bottom groove 204 is symmetrically distributed about the axis of symmetry of the top plate 201.

[0031] Start the moving wheel 102. The moving wheel 102 can drive the bracket 101 to move. The bracket 101 drives the hydraulic cylinder 103 to move. Since the top plate 201 is connected to the hydraulic cylinder 103, the top plate 201 and the parts connected to the top plate 201 will move synchronously. That is, the driving mechanism 3, the positioning mechanism 4, and the fixing mechanism 5 will also move horizontally accordingly, making the entire connecting mechanism 2 move horizontally synchronously with the hydraulic cylinder 103;

[0032] Start the hydraulic cylinder 103. The hydraulic cylinder 103 can drive the top plate 201 to move in the vertical direction. At this time, the top plate 201 can drive the side plate 202 to move vertically. The side plate 202 drives the first guide rod 203 to move vertically. The first guide rod 203 drives the support plate 501 to move vertically, so that the fixing mechanism 5 can move vertically synchronously. At the same time, the top plate 201 will also drive the bottom groove 204 to move vertically, making the driving mechanism 3 follow the bottom groove 204 to move vertically, and then making the positioning mechanism 4 follow the driving mechanism 3 to move vertically.

[0033] Refer to the appendix Figures 4-8 As shown in the figure, the positioning mechanism 4 includes a connecting plate 401, a push rod motor 402, and a positioning plate 403. One end of the rack 305 is connected to the connecting plate 401. The side wall of the connecting plate 401 is connected to the push rod motor 402. The output end of the push rod motor 402 is connected to the positioning plate 403.

The side wall of the connecting block 301 is connected to the second guide rod 302. The rotating motor 306 is connected to the inner top end of the bottom groove 204. The output end of the rotating motor 306 is connected to the gear 304. A plurality of sliders 303 are connected to the top end of the rack 305. The side wall of the slider 303 is slidably connected to the second guide rod 302. The two racks 305 are symmetrically distributed with respect to the gear 304. The side wall of the rack 305 meshes with the gear 304. The rotating gear 304 is located at the center of the bottom groove 204. The slider 303 is provided with a sliding hole to slide with the second guide rod 302.

[0035] The positioning plate 403 is initially in a contracted state, and the top plate 201 is initially located above the steel member 6. Start the rotary motor 306. The rotary motor 306 drives the gear 304 to rotate. The gear 304 drives the two racks 305 to move in the outer end directions on both sides respectively. The rack 305 drives the slider 303 to move along the second guide rod 302, so that the rack 305 drives the connecting plate 401 to move outwards. The connecting plate 401 drives the push rod motor 402 to move. The push rod motor 402 drives the positioning plate 403 to move horizontally. Then, drive the push rod motor 402 again to make the positioning plate 403 move downwards, so that the two positioning plates 403 are respectively located on the outer sides of both sides of the steel member 6. At this time, mark at the central positions on both sides of the steel member 6. Then, the bracket 101 moves, causing the top plate 201 to move. The top plate 201 drives the driving mechanism 3 to move as a whole, thereby causing the positioning plate 403 to move, making the positioning plate 403 move to be in contact with the central position of the side wall of the steel member 6. Then, pull the positioning plate 403 upwards. At the same time, push the top plate 201 downwards, causing the top plate 201 to drive the driving mechanism 3 to move downwards, and the driving mechanism 3 drives the positioning mechanism 4 to move downwards, so that the top plate 201 is located at the symmetry axis of the steel member 6, avoiding uneven force on the fixing mechanisms 5 located on both sides.

[0036] Refer to the appendix Figures 5-8 The fixing mechanism 5 includes a support plate 501, a bottom plate 502, a support block 503, a connecting shaft 504, a round shaft 505, a limit screw 506, a pressing plate 507, a pressing screw 508 and a round hole 509. A plurality of support plates 501 are movably connected to the side wall of the first guide rod 203. A support block 503 is connected to the top end of the bottom plate 502. A connecting shaft 504 is connected to the side wall of the support block 503. The side wall of the connecting shaft 504 is rotatably connected to the bottom end of the support plate 501. Two symmetrically distributed round shafts 505 are connected to the inner side wall of the bottom plate 502. A pressing plate 507 is slidably connected to the side wall of the round shaft 505. A pressing screw 508 is threadedly connected to the side wall of the pressing plate 507. A round hole 509 is opened at the bottom end of the bottom plate 502. A limit screw 506 is threadedly connected to the side wall of the bottom plate 502. The shape of the bottom plate 502 is U-shaped. The length of the top end of the bottom plate 502 is less than the length of the bottom end of the bottom plate 502. A rubber pad is connected to one end of the limit screw 506. The support plate 501 and the first guide rod 203 are movably connected through a through hole.

[0037] First, move the support plate 501 downward so that the coupling shaft 504 drives the bottom plate 502 to move to both sides of the steel member 6 located below. Then, rotate the support plate 501 to expand it outward. The support plate 501 drives the coupling shaft 504 to rotate outward, and the coupling shaft 504 drives the bottom plate 502 to move outward, so that the two symmetrically distributed bottom plates 502 are expanded, thereby realizing the adjustment of the distance between the bottom plates 502 to adapt to the length of the steel member 6. Since the bottom plate 502 can be rotatably connected to the support plate 501 through the coupling shaft 504, the bottom plate 502 can adjust the inclination angle to adapt to the inclined surface on the surface of the steel member 6. At this time, the bottom plate 502 is clamped onto the surface of the steel member 6 so that the inner bottom end of the bottom plate 502 is in contact with the bottom end of the steel member 6. Then, press down the pressing plate 507. The pressing plate 507 is in contact with the top end of the steel member 6, and the pressing screw 508 is screwed into the round hole 509 to press the pressing plate 507, thereby realizing the effect of clamping the steel member 6 by the bottom plate 502 and the pressing plate 507, achieving the effect of being able to fix steel members 6 of various lengths and with inclined surfaces at the bottom. The limiting screw 506 can further press on the side wall of the steel member 6 to improve the fixing effect on the steel member 6.
