Description

Technical Field

[0001] This invention belongs to the field of steel structure building technology, and particularly relates to a steel structure docking fixture. Background Technology

[0002] Steel structure buildings are a new type of building system that breaks down the boundaries between the real estate, construction, and metallurgical industries, bringing them together into a new industrial system. This is the steel structure building system that is generally favored by industry insiders.

[0003] Compared to traditional concrete buildings, steel structure buildings use steel plates or profiles instead of reinforced concrete, resulting in higher strength and better earthquake resistance. Furthermore, because components can be factory-made and installed on-site, construction time is significantly reduced. The reusability of steel greatly reduces construction waste, making it more environmentally friendly, and thus it is widely used in industrial and civil buildings worldwide.

[0004] Before welding, two steel members in a steel structure typically need to be butt-jointed and then welded together using a welding machine. Due to the need to adapt to different building types, the butt joint surfaces of the two steel members must be brought together at a specific angle before welding can proceed. However, existing equipment often cannot perform multi-angle butt joints of steel members of different sizes, making operation inconvenient and affecting welding efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a steel structure docking fixture, which aims to solve the problems mentioned in the background art.

[0006] This invention is implemented as follows: a steel structure docking fixture includes a first docking portion and a second docking portion. The first docking portion includes a first docking seat, and a first connecting seat is provided at the end of the first docking seat. The second docking portion includes a second docking seat, and a second connecting seat is provided at the end of the second docking seat. A rotating column is connected to the bottom of the second connecting seat, and the rotating column is rotatably mounted on the first connecting seat. The fixture also includes:

[0007] The docking mechanism includes a docking frame slidably mounted on the first or second docking seat. The docking frame is U-shaped, and the bottom of both the second and first docking seats is provided with a drive assembly for linearly sliding the docking frame. The docking frame is symmetrically mounted on both sides for laterally clamping and fixing the steel. The clamping assembly includes an installation sleeve mounted on the end of the docking frame. A driven shaft is rotatably mounted in the installation sleeve. The docking frame is also provided with an adjustment assembly for rotating the driven shaft. A threaded push rod is connected to the driven shaft via a sliding key. The threaded push rod is threadedly connected to the inside of the installation sleeve. A clamping side plate is provided at the end of the threaded push rod away from the driven shaft.

[0008] The positioning assembly includes a sliding seat that is slidably mounted on a second connecting seat along the axial direction of a rotating column, and the sliding seat is coaxial with the rotating column. The bottom of the sliding seat is connected to the interior of the second connecting seat through a return spring. When the return spring is in a free state, the upper surface of the sliding seat is flush with the upper surface of the second connecting seat. The sliding seat is provided with a positioning protrusion, which is in the shape of a semi-frustum. The side of the positioning protrusion near the first docking seat is a vertical surface, and the side of the positioning protrusion near the second docking seat is a frustum surface.

[0009] In a further technical solution, the second docking part also includes an adjustment motor installed at the bottom of the first docking seat, and the adjustment motor is connected to the rotating column for driving the rotating column to rotate.

[0010] In a further technical solution, the drive assembly includes a mounting plate, which is installed on the bottom of the first docking seat or the second docking seat. A hydraulic telescopic rod is mounted on the mounting plate, and the movable end of the hydraulic telescopic rod is connected to the docking frame.

[0011] In a further technical solution, the first docking seat is further provided with a plurality of first rollers arranged side by side, and the second docking seat is further provided with a plurality of second rollers arranged side by side.

[0012] In a further technical solution, the adjustment component includes a drive motor, with a drive shaft connected to each end of the drive motor, and the two drive shafts are respectively connected to the driven shaft in a set of clamping components.

[0013] In a further technical solution, the end of the driven shaft away from the clamping side plate is located outside the mounting sleeve, and the drive shaft is connected to that end of the driven shaft via a pulley and belt mechanism.

[0014] A further technical solution is that both the first connecting seat and the second connecting seat are provided with clearance holes, which facilitates the operator to spot weld the steel from the bottom, thereby quickly completing the connection of the two steel pieces.

[0015] This invention provides a steel structure welding fixture. In use, the second docking seat rotates around a rotating column, thereby adjusting the angle between the first and second docking seats to accommodate welding requirements at different angles. After adjustment to the specified angle, two steel pieces are placed in the first and second docking seats respectively. Then, the adjustment assembly is activated, causing two driven shafts on the same docking frame to rotate synchronously. The driven shafts can drive threaded push rods to rotate synchronously. Under the threaded engagement between the threaded push rod and the mounting sleeve, the threaded push rod simultaneously rotates and slides linearly along the axial direction of the driven shaft. The threaded push rod can push the clamping side plates to move synchronously, thereby fixing the sidewalls of the steel pieces through the two clamping side plates. At this time, the drive assembly is activated, causing the docking frame to move towards the rotating column. During this process, firstly, one end of the steel piece located on the first docking seat moves to the rotating column, causing the end of the steel piece to abut against the vertical surface of the positioning protrusion, thus positioning the first steel piece. Then, the steel piece located on the second docking seat moves to the rotating column. During this process, the end of the steel bar continuously presses against the frustum surface of the positioning protrusion (i.e., the arc-shaped side of the positioning protrusion), eventually causing the positioning protrusion to fully retract into the second connecting seat. At this point, the surfaces of the two steel bars to be welded abut against each other, allowing for spot welding and positioning of the two steel bars, facilitating subsequent rapid welding. This device can effectively perform butt welding of steel bars of different sizes at different angles, significantly improving the efficiency of steel butt welding, reducing the operational difficulty of steel butt welding, and is simple to operate, widely applicable, and effective.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0026] like Figure 1-5 As shown, a steel structure docking fixture provided in one embodiment of the present invention includes a first docking portion 1 and a second docking portion 2. The first docking portion 1 includes a first docking seat 11, and a first connecting seat 12 is provided at the end of the first docking seat 11. The second docking portion 2 includes a second docking seat 21, and a second connecting seat 22 is provided at the end of the second docking seat 21. A rotating column 24 is connected to the bottom of the second connecting seat 22, and the rotating column 24 is rotatably mounted on the first connecting seat 12. The fixture also includes:

[0027] The docking mechanism 3 is provided on both the first docking seat 11 and the second docking seat 21. The docking mechanism 3 includes a docking frame 31 slidably mounted on the first docking seat 11 or the second docking seat 21. The docking frame 31 is U-shaped. The bottom of the second docking seat 21 and the first docking seat 11 are provided with a driving component 4 for driving the docking frame 31 to slide linearly. The two sides of the docking frame 31 are symmetrically mounted with clamping components for lateral clamping and fixing of steel. The clamping components include an installation sleeve 33 mounted on the end of the docking frame 31. A driven shaft 32 is rotatably mounted in the installation sleeve 33. The docking frame 31 is also provided with an adjustment component 5 for driving the driven shaft 32 to rotate. A threaded push rod 35 is connected to the driven shaft 32 by a sliding key. The threaded push rod 35 is threadedly connected to the inside of the installation sleeve 33. A clamping side plate 34 is provided at the end of the threaded push rod 35 away from the driven shaft 32.

[0028] The positioning component 6 includes a sliding seat 61 slidably mounted on the second connecting seat 22 along the axial direction of the rotating column 24, and the sliding seat 61 is coaxial with the rotating column 24. The bottom of the sliding seat 61 is connected to the interior of the second connecting seat 22 through a return spring 63. When the return spring 63 is in a free state, the upper surface of the sliding seat 61 is flush with the upper surface of the second connecting seat 22. The sliding seat 61 is provided with a positioning protrusion 62, which is in the shape of a semi-frustum. The side of the positioning protrusion 62 near the first docking seat 11 is a vertical surface, and the side of the positioning protrusion 62 near the second docking seat 21 is a frustum surface.

[0029] In this embodiment of the invention, during use, the second docking seat 21 rotates around the rotating column 24, thereby adjusting the angle between the first docking seat 11 and the second docking seat 21 to adapt to the welding requirements of steel structures at different angles. After adjusting to the specified angle, place the two steel pieces in the first docking seat 11 and the second docking seat 21 respectively. Then, start the adjustment component 5. The adjustment component 5 drives the two driven shafts 32 on the same docking frame 31 to rotate synchronously. The driven shafts 32 can drive the threaded push rods 35 to rotate synchronously. Under the threaded engagement between the threaded push rods 35 and the mounting sleeves 33, the threaded push rods 35 will also slide linearly along the axial direction of the driven shafts 32. The threaded push rods 35 can push the clamping side plates 34 to move synchronously, thereby fixing the side walls of the steel pieces through the two clamping side plates 34. At this time, start the drive component 4. The drive component 4 can drive the docking frame 31 to move towards the side closer to the rotating column 24. In this process, firstly, one end of the steel piece located on the first docking seat 11 moves to the rotating column 24, and the end of the steel piece abuts against the vertical surface of the positioning protrusion 62 to achieve the positioning of the first steel piece. Then, the steel piece located on the second docking seat 21 moves to the rotating column 24. During this process, the end of the steel will continuously press against the frustum surface of the positioning protrusion 62 (i.e., the arc-shaped side surface of the positioning protrusion 62), eventually causing the positioning protrusion 62 to be completely retracted into the second connecting seat 22. At this time, the surfaces of the two steels to be welded will abut against each other, so that the two steels can be spot welded and positioned, which will facilitate subsequent rapid welding.

[0030] After welding is completed and the two steel pieces are removed, the sliding seat 61 will push the positioning protrusion 62 to automatically return to its initial position under the elastic restoring force of the return spring 63, so that subsequent positioning operations can be performed.

[0031] like Figure 1 and 5 As shown, in a preferred embodiment of the present invention, the second docking part 2 further includes an adjustment motor 25 installed at the bottom of the first docking seat 11, and the adjustment motor 25 is connected to the rotating column 24 for driving the rotating column 24 to rotate.

[0032] In this embodiment of the invention, specifically, the adjusting motor 25 is connected to the rotating column 24 via a pulley and belt mechanism. The adjusting motor 25 can drive the rotating column 24 to rotate via the pulley and belt mechanism. The rotating column 24 can drive the second docking seat 21 to rotate via the second connecting seat 22, thereby adjusting the relative angle between the second docking seat 21 and the first docking seat 11.

[0033] like Figure 1 and 5As shown, in a preferred embodiment of the present invention, the drive assembly 4 includes a mounting plate 41, which is mounted on the bottom of the first docking seat 11 or the second docking seat 21. A hydraulic telescopic rod 42 is mounted on the mounting plate 41, and the movable end of the hydraulic telescopic rod 42 is connected to the docking frame 31.

[0034] In this embodiment of the invention, when in use, the hydraulic telescopic rod 42 can drive the docking frame 31 to slide along the first docking seat 11 or the second docking seat 21 through its telescopic movement, thereby adjusting the distance between the two docking frames 31 and realizing the docking of the steel pipe.

[0035] like Figure 1 and 2 As shown, in a preferred embodiment of the present invention, the first docking seat 11 is further provided with a plurality of first rollers 13 arranged side by side, and the second docking seat 21 is further provided with a plurality of second rollers 23 arranged side by side.

[0036] In this embodiment of the invention, the steel to be welded is placed directly on the first roller 13 or the second roller 23 during use, thereby ensuring that the steel will not generate significant friction with the upper surface of the first docking seat 11 or the second docking seat 21 during the movement process, improving the smoothness of the docking operation, and also reducing the power consumption of the hydraulic telescopic rod 42.

[0037] like Figure 1 and 3 As shown, in a preferred embodiment of the present invention, the adjustment component 5 includes a drive motor 51, and each end of the drive motor 51 is connected to a drive shaft 52, and the two drive shafts 52 are respectively connected to the driven shaft 32 in a set of clamping components.

[0038] In this embodiment of the invention, the end of the driven shaft 32 away from the clamping side plate 34 is located outside the mounting sleeve 33, and the drive shaft 52 is connected to this end of the driven shaft 32 via a pulley and belt mechanism. In use, the drive motor 51 can drive the drive shaft 52 to rotate, and the drive shaft 52 drives the driven shaft 32 to rotate via the pulley and belt mechanism, thereby enabling the simultaneous operation of two sets of clamping components on the same docking frame 31.

[0039] like Figure 1 , 2 As shown in Figure 5, in a preferred embodiment of the present invention, both the first connecting seat 12 and the second connecting seat 22 are provided with clearance holes, which facilitates the operator to spot weld the steel from the bottom, thereby quickly completing the connection of the two steel pieces.

[0040] Working principle: In use, the second docking seat 21 rotates around the rotating column 24, thereby adjusting the angle between the first docking seat 11 and the second docking seat 21 to adapt to the welding requirements of steel structures at different angles. After adjusting to the specified angle, the two steel pieces are placed in the first docking seat 11 and the second docking seat 21 respectively. Then, the adjustment component 5 is activated, and the drive motor 51 drives the drive shaft 52 to rotate. The drive shaft 52 drives the two driven shafts 32 on the same docking frame 31 to rotate synchronously through the pulley belt mechanism. The driven shafts 32 can drive the threaded push rods 35 to rotate synchronously. Under the threaded engagement between the threaded push rods 35 and the mounting sleeve 33, the threaded push rods 35 will also slide linearly along the axial direction of the driven shafts 32. The threaded push rods 35 can push the clamping side plates 34 to move synchronously, thereby fixing the side walls of the steel pieces through the two clamping side plates 34. At this time, the drive component 4 is activated. The hydraulic telescopic rod 42 in the drive component 4 can drive the docking frame 31 to move closer to the rotating column 24 through its telescopic movement. In this process, firstly, one end of the steel on the first docking seat 11 moves to the rotating column 24, and the end of the steel abuts against the vertical surface of the positioning protrusion 62, thus positioning the first steel. Then, the steel on the second docking seat 21 moves to the rotating column 24. During this process, the end of the steel continuously presses against the frustum surface of the positioning protrusion 62 (i.e., the arc-shaped side surface of the positioning protrusion 62), eventually causing the positioning protrusion 62 to completely retract into the second connecting seat 22. At this time, the surfaces of the two steels to be welded abut against each other, thus enabling spot welding positioning of the two steels, facilitating subsequent rapid welding.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
