Description

Technical Field

[0001] The present application relates to the technical field of steel structure docking, and in particular to a steel structure docking device for construction. Background Art

[0002] During the construction process, steel structures are often used as the main support frame of the building. Common steel structures are I-beams and square steels, which are generally used for building columns and beams. Some steel structures are also used on trusses.

[0003] Depending on the requirements of the construction, steel structures require different degrees and requirements of butt welding to extend their length. The joints also require corresponding structural reinforcement based on the load distribution. During the butt welding process of the two ends of the steel structure, the two sections of the steel structure are often lifted and fixed on the butt platform using a sling, and then the butt joint is welded. Among them, workers are more laborious when welding the bottom of the steel structure, and due to the construction angle problem, the welding quality of the bottom of the steel structure is poor, which leads to poor bottom welding quality and low welding efficiency after the steel structure is butt welded.

When the card is in contact with the placement platform, it is in a horizontal state and cannot be rotated downward. The vertical plate is vertically fixed to the bottom plate and is located above the rotation axis of the bottom plate.

[0010] The turning wheel is fixed on the turning plate, partially located in the turning groove, with its center collinear with the rotation axis of the bottom plate, and teeth distributed on its circumferential outer wall;

[0013] The first telescopic cylinder is horizontally mounted on the support frame and is located on the side of the vertical plate away from the bottom plate. The piston rod is fixed with a rack that can mesh with the teeth of the flip wheel and drive the bottom plate to rotate upward. The rack does not contact the teeth of the flip wheel in its initial position.

[0014] The locking frame is tilted toward the top of one side of the rack, and the bottom of the end of the rack is tilted and can abut against the locking frame until the locking frame is separated from the locking plate;

Then, the ends of the two sections of steel structure are pushed together to abut each other before welding begins. When welding the bottom, the second telescopic cylinder is reset and the first telescopic cylinder is extended. The rack meshes with the teeth of the flip wheel to drive the flip plate to flip, thereby exposing the bottom of the steel structure, improving the efficiency and quality of the bottom welding of the steel structure.

[0023] 2. The rack is then engaged with the flip wheel, so that the flip wheel can be kept more stably in the state before flipping;

[0024] 3. Due to the abutment between the locking frame and the locking plate, the steel structure will not cause the flip plate to flip when it abuts the vertical plate.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a steel structure docking device for construction.

[0032] refer to Figure 1 and Figure 2The steel structure docking device for construction includes a support frame 1, a flip plate 2, a first telescopic cylinder 3 and a second telescopic cylinder 5. The top of the support frame 1 is a placement platform 11, and a plurality of flip grooves 12 are provided on the upper surface of the placement platform 11. The flip plate 2 is rotatably connected in the flip groove 12. The flip plate 2 includes a bottom plate 22 and a vertical plate 21. The bottom plate 22 is rotatably connected in the flip groove 12. Cards 222 are fixed on both sides of the bottom plate 22. When the card plates 222 are in contact with the placement platform 11, they are in a horizontal state and cannot be rotated downward. The vertical plate 21 is vertically fixed on the bottom plate 22 and is located above the rotation axis of the bottom plate 22. A sink 221 is provided on the upper surface of the vertical plate 21. A plurality of rotating rollers 2211 are rotatably connected in the sink 221. The rotation axis of the rotating roller 2211 is parallel to the rotation axis of the bottom plate 22. A flip wheel 211 is fixedly provided on the flip plate 2. The center of the flip wheel 211 is colinear with the rotation axis of the flip plate 2. The flip wheel 211 is located below the bottom plate 22 and on the side of the vertical plate 21 away from the bottom plate 22. Teeth are distributed on the circumferential outer wall of the flip wheel 211. The first telescopic cylinder 3 is horizontally mounted on the support frame 1 and is located on the side of the vertical plate 21 away from the bottom plate 22. The piston rod of the first telescopic cylinder 3 is fixedly provided with a rack 31, which is slidingly connected to the support frame 1. The rack 31 can mesh with the flip gear and drive the bottom plate 22 to rotate upward. The rack 31 does not contact the teeth of the flip wheel 211 in its initial position. The support frame 1 is provided with a locking assembly 4 that releases the rotation restriction of the flip wheel 211 only when the rack 31 is pushed out.

[0033] The second telescopic cylinder 5 is horizontally mounted on the support frame 1, opposite the vertical plate 21 and located on the side of the vertical plate 21 facing the bottom plate 22. A push plate 51 is fixed to the end of the second telescopic cylinder 5. Extension components 6 are installed on both sides of the support frame 1 to support the ends of the steel structure.

[0034] When the steel structure needs to be butt-welded, the two sections of the steel structure are hoisted onto the bottom plate 22, and the rotation of the flip plate 2 is restricted by the fixing assembly. Subsequently, the piston rod of the second telescopic cylinder 5 is extended, and the steel structure is pressed against the vertical plate 21 through the push plate 51, and the two ends of the steel structure are pushed into contact, and then welding and other forms of reinforcement are performed on the connection of the steel structure. When the bottom of the steel structure needs to be welded and reinforced, the second telescopic cylinder 5 is reset, and the piston rod of the first telescopic cylinder 3 is extended, and the locking assembly 4 releases the rotation restriction of the flip plate 2 by moving the rack 31. When the rack 31 engages with the flip wheel 211, it drives the flip plate 2 to rotate, and then drives the steel structure to flip, so that the bottom connection of the steel structure is exposed, which is convenient for welding and reinforcement, reduces the situation where workers bend or lean over when welding, and improves the efficiency and quality of the butt welding and fixing of the steel structure.

[0035] refer to Figure 2The locking assembly 4 includes a locking frame 41 and a locking plate 42. The locking plate 42 is fixed on both sides of the flip wheel 211 and is located directly below the vertical plate 21. The locking frame 41 is vertically arranged and vertically slidably mounted on the support frame 1, and the locking frame 41 is located below the flip wheel 211. The support frame 1 is fixed with a first spring 411, and the other end of the first spring 411 is fixedly connected to the locking frame 41, so that the top of the locking frame 41 can be located on the side of the locking plate 42 facing the bottom plate 22 and abut against the locking plate 42. The locking frame 41 is tilted toward the top of one side of the rack 31, and the bottom end of the rack 31 is tilted and can abut against the locking frame 41 to the position where the locking frame 41 and the locking plate 42 are separated.

[0036] When the second telescopic cylinder 5 drives the steel structure into contact with the vertical plate 21, the locking plate 42 abuts the locking frame 41, preventing the flip plate 2 from rotating. By arranging the rack 31 to engage with the flip wheel 211 after movement, the rack 31 can first move the locking frame 41 downward to a position where it is not opposite the locking plate 42, thereby releasing the rotation restriction on the flip plate 2. This improves the stability of the flip plate 2's position.

[0037] refer to Figure 3 The extension assembly 6 includes a sub-frame 61 and an extension rod 62. There are multiple sub-frames 61, each located at each end of the support frame 1. The extension rod 62 is fixed to the middle of the sub-frame 61, with the extension rods 62 on different sub-frames 61 at the same end of the support frame 1 staggered. The extension rod 62 of the sub-frame 61 adjacent to the support frame 1 is slidably connected to the support frame 1, while the extension rods 62 of the remaining sub-frames 61 are slidably connected to the adjacent sub-frames 61 on the side closest to the support frame 1. Structural openings are provided on the support frame 1 and sub-frame 61 for the extension rod 62 to slide. The end of the extension rod 62 is rotatably connected to an abutment wheel 621, the rotation axis of which is horizontally disposed. A flip groove 12 is also provided on the sub-frame 61. The flip plate 2 is rotatably connected within the flip groove 12 of the sub-frame 61 and is positioned opposite the flip plate 2 of the main frame. The rotation axis of the flip plate 2 of the sub-frame 61 is equipped with a torsion spring that maintains the bottom plate 22 in a horizontal position.

[0038] When the steel structure is long, the sub-frame 61 can be pulled out to support the bottom portion of the steel structure, thereby improving the stability of the steel structure during placement, improving the quality and effectiveness of the steel structure welding, and also improving the stability of the steel structure during flipping. The provision of extension rods 62 and the staggered arrangement can make the sliding of sub-frame 61 more stable and the structural distribution more reasonable. The provision of abutment wheels 621 can enable the sub-frame 61 to slide more effectively onto the corresponding sliding structure.

[0039] The implementation principle of a steel structure docking device for construction in an embodiment of the present application is as follows: after the two steel structures that need to be butt-welded and fixed are moved to the base plate 22 by a lifting device, the piston rod of the second telescopic cylinder 5 is pushed out to make the steel structure press against the vertical plate 21, and then the connection between the two steel structures is welded and fixed. When it is necessary to weld and fix the bottom of the steel structure, the piston rod of the first telescopic cylinder 3 is extended, so that the rack 31 first abuts against the locking frame 41 and presses the locking frame 41 downward, so that the locking frame 41 and the locking plate 42 are staggered, and the rotation restriction of the flip plate 2 is released. Subsequently, the rack 31 engages with the flip wheel 211 to drive the flip plate 2 to rotate, thereby realizing the flipping of the steel structure, exposing the bottom of the steel structure, and making it easier for workers to weld and fix the bottom of the steel structure, thereby improving the efficiency and quality of multi-section fixing of the steel structure. Therefore, the efficiency of on-site pre-docking and fixing of steel structures can be improved during construction.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
