Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology, and more specifically, to an auxiliary device for steel structure construction. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are mainly composed of beams, columns, trusses, and other components made of steel sections and plates. The various components or parts of a steel structure are typically connected by welds, bolts, or rivets. Due to their light weight and ease of construction, steel structures are widely used in large factories, stadiums, and high-rise buildings. Current steel structure connections are usually made by welding. However, the steel structure needs to be positioned before welding. Existing positioning devices are generally fixed to a workbench, making it impossible to position and rotate steel structures of different specifications, which can sometimes cause difficulties for construction workers.

[0003] Chinese patent CN 215546030 U discloses a clamping and straightening device for steel structure welding. This device uses a screw to drive a motor that rotates a rotating shaft, which in turn rotates a second bevel gear and simultaneously rotates a first bevel gear. A triangular connecting plate is rotatably connected to an L-shaped mounting plate; the extension of a telescopic electric cylinder allows the triangular connecting plate to rotate. This rotation causes short and long connecting rods to move upwards, and the two pressure plates rotate through the short and long connecting rods. While this solution can clamp and rotate steel structures, its structure and operation are complex, and it cannot remove fumes during the welding process.

[0004] Therefore, developing an auxiliary device for fixing, rotating, and welding steel structures that is simple in structure and easy to operate is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] Due to the aforementioned deficiencies in the existing technology, the present invention provides a steel structure construction auxiliary device to solve the problems of facilitating the fixing, rotation, and welding of steel structures.

[0006] To achieve the above objectives, the present invention provides a steel structure construction auxiliary device, characterized in that it includes a load-bearing frame, a clamping mechanism, and a rotating mechanism; the clamping mechanism and the rotating mechanism are located between two load-bearing frames, and the clamping mechanism is located between the rotating mechanisms;

[0007] The rotating mechanism includes a first motor, a rotating drum, a locking block, a connecting plate, and a connecting shaft. The first motor is located on one side of the load-bearing frame, the connecting shaft is installed at the output end of the first motor, and one end of the connecting plate is located at the other end of the connecting shaft. The connecting plate is engaged between the locking blocks, and the rotating drum is arranged on the outside of multiple locking blocks. The rotating drum, the locking blocks, and the connecting plate are symmetrically installed on the other side of the load-bearing frame. Multiple square slots are opened inside the rotating drum, and tension springs are arranged in the square slots. The output end of the first motor is keyed to the connecting shaft, the connecting plate is fixedly connected to the connecting shaft, and the connecting shaft is rotatably connected to the rotating drum.

[0008] The clamping mechanism includes a second motor, a connecting frame, a threaded rod, a first fixed frame, a connecting barrel, a first electric push rod, a fixed barrel, a second electric push rod, and a second fixed frame. The connecting barrel is installed between the two connecting plates. The first electric push rod is located at the bottom of the connecting barrel, and the fixed barrel is installed above the first electric push rod. Connecting frames are provided on both sides above the connecting barrel, and a second motor is provided on one side of each connecting frame. Two threaded rods are provided between the two connecting frames. The threads on both sides of the threaded rods are arranged in opposite directions, and pulleys are installed on both of them. Belts are provided on the two pulleys. The threaded rods are rotatably connected to the connecting frames. The two threaded rods are respectively threadedly connected to the two first fixed frames. The two second electric push rods are located above the first fixed frames, and the telescopic parts of the two second electric push rods are each installed with a second fixed frame. The telescopic parts of the second electric push rods are rotatably connected to the second fixed frames.

[0009] The working principle of the device is as follows: A second motor drives the threaded rods to rotate, which in turn causes the two threaded rods to rotate synchronously via a belt. Since the threads on both sides of the two threaded rods are opposite, this causes the two first fixed frames to move closer together to clamp the steel structure. The bottom end of the steel structure is inserted into the fixed barrel, and the height of the steel structure can be adjusted by the action of the first electric push rod. The upper end of the steel structure is clamped by the action of the two second electric push rods, which in turn causes the second fixed frame to clamp the steel structure. Then, the first motor drives the connecting shaft to rotate counterclockwise, causing the connecting plate to rotate counterclockwise between the locking blocks inside the rotating drum. During rotation, the connecting plate compresses one side of the inclined surface of the locking block, pressing it down into the square groove inside the rotating drum. When the connecting plate rotates to the straight side, the locking block is springed back to its original position by the tension spring in the square groove, locking the connecting plate. The angle of the steel structure can be adjusted by the counterclockwise rotation of the connecting plate.

[0010] Furthermore, bellows are installed above the second electric push rod on one side of the two load-bearing frames, and each bellows contains a fan. During the welding process of the steel structure, the fans in the two bellows rotate in opposite directions to create air convection, thereby absorbing the gases generated during welding.

[0011] Furthermore, the fan is equipped with a portable small motor, and the air box is equipped with a filter. This feature facilitates the fan's filtering of dust from the air.

[0012] Furthermore, a compression spring is installed at the bottom of the connecting barrel, and the first electric push rod is located above the compression spring. This feature can cushion the steel structure placed inside the connecting barrel.

[0013] Furthermore, two symmetrical first fixing frames are installed between the two threaded rods. Each of the two first fixing frames has four small holes, and each of the four small holes has a screw inside.

[0014] Furthermore, four limiting rods are evenly installed on opposite sides of the two first fixed frames, with each end of the limiting rods fixed to one of the two first fixed frames. This feature limits the maximum size of the frame formed by the two first fixed frames.

[0015] Furthermore, each of the second fixing frames is equipped with a telescopic spring. This feature provides a cushioning effect and is suitable for clamping steel structures of different diameters.

[0016] Compared with the prior art, the above invention has the following advantages or beneficial effects:

[0017] (1) By rotating the connecting plate counterclockwise, the side of the clamping block with the inclined surface is compressed into the square groove of the rotating drum by the spring. Then, when the connecting plate rotates to the straight side of the clamping block, the clamping block springs back to its original state by the spring, so that the connecting plate is clamped between the clamping blocks. Therefore, the angle of the steel structure can be adjusted at any time by the size of the rotation amplitude, making the operation of the steel structure more convenient.

[0018] (2) The two-layer clamping mechanism makes the steel structure more secure, while saving manpower and improving the safety of welding;

[0019] (3) The device has a simple structure and reasonable design. The height of the steel structure can be easily adjusted up and down. The addition of a fan can also help to remove the fumes generated during welding as quickly as possible. Attached Figure Description

Detailed Implementation

[0028] The structure of the present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0029] Example 1

[0030] like Figure 1 As shown, a steel structure construction auxiliary device includes a load-bearing frame 1, a clamping mechanism 3, and a rotating mechanism 4; the clamping mechanism 3 and the rotating mechanism 4 are located between two load-bearing frames 1, and the clamping mechanism 3 is located between the rotating mechanisms 4.

[0031] like Figure 2 and Figure 3 As shown, the rotating mechanism 4 includes a first motor 41, a rotating drum 42, a locking block 43, a connecting plate 44, and a connecting shaft 45. The first motor 41 is disposed on one side of the load-bearing frame 1, the connecting shaft 45 is installed at the output end of the first motor 41, and one end of the connecting plate 44 is disposed at the other end of the connecting shaft 45. The connecting plate 44 is engaged between the locking blocks 43, and the rotating drum 42 is disposed on the outside of the plurality of locking blocks 43. The rotating drum 42, the locking blocks 43, and the connecting plate 44 are symmetrically installed on the other side of the load-bearing frame 1. The rotating drum 42 has a plurality of square grooves inside, and tension springs 46 are disposed in the square grooves. The output end of the first motor 41 is keyed to the connecting shaft 45, the connecting plate 44 is fixedly connected to the connecting shaft 45, and the connecting shaft 45 is rotatably connected to the rotating drum 42.

[0032] like Figure 4 and 5 As shown, the clamping mechanism 3 includes a second motor 31, a connecting frame 32, a threaded rod 33, a first fixing frame 34, a connecting barrel 35, a first electric push rod 36, a fixing barrel 37, a second electric push rod 38, and a second fixing frame 39. The connecting barrel 35 is installed between the two connecting plates 44. The first electric push rod 36 is located at the bottom of the connecting barrel 35, and a compression spring is installed at the bottom of the connecting barrel 35. The first electric push rod 36 is located above the compression spring. The fixing barrel 37 is installed above the first electric push rod 36. Connecting frames 32 are provided on both sides of the upper part of the connecting barrel 35, and a second electric push rod is provided on one side of the connecting frame 32. The machine 31 has two threaded rods 33 arranged between two connecting frames 32; the threads on both sides of the threaded rods 33 are arranged in opposite directions, and each is equipped with a pulley, with a belt on each pulley; the threaded rods 33 are rotatably connected to the connecting frames 32; the two threaded rods 33 are respectively threadedly connected to the two first fixed frames 34; the two second electric push rods 38 are located above the first fixed frames 34, and the telescopic parts of the two second electric push rods 38 are each equipped with a second fixed frame 39, and the telescopic parts of the second electric push rods 38 are rotatably connected to the second fixed frames 39; each of the second fixed frames 39 is equipped with a telescopic spring.

[0033] like Figure 1 and 6 As shown, in this embodiment, the two load-bearing frames 1 are close to each other on one side, and a wind box 2 is provided above the second electric push rod 38. A fan 5 is installed inside the wind box 2.

[0034] In this embodiment, two symmetrical first fixing frames 34 are installed between the two threaded rods 33. Each of the two first fixing frames 34 has four small holes, and screws are installed inside each of the four small holes. Four limiting rods 30 are evenly installed on opposite sides of the two first fixing frames 34, and the two ends of each limiting rod 30 are respectively fixed to the two first fixing frames 34.

[0035] When the device is working, the second motor 31 drives the threaded rod 33 to rotate, thereby causing the two threaded rods 33 to rotate synchronously via a belt; since the threads on both sides of the two threaded rods 33 are opposite, the two first fixed frames 34 are driven to move closer to each other to clamp the steel structure. The bottom of the steel structure is inserted into the fixed bucket 37. The first electric push rod 36 can adjust the height of the steel structure. At the same time, the compression spring below can also play a buffering role. The upper end of the steel structure is driven by two second electric push rods 38 to drive the second fixed frame 39 to clamp the steel structure. At the same time, the telescopic spring inside the second fixed frame 39 can play a buffering role and can clamp steel structures of different diameters. Then, the first motor 41 drives the connecting shaft 45 to rotate counterclockwise, thereby driving the connecting plate 44 to rotate counterclockwise between the locking blocks 43 in the rotating drum 42. When rotating, the connecting plate 44 will compress one side of the inclined surface of the locking block 43 and press it down into the square groove in the rotating drum 42. When the connecting plate 44 rotates to the straight side, the locking block 43 is springed back to its original position by the elastic force of the tension spring in the square groove, thus locking the connecting plate 44. The angle of the steel structure can be adjusted by the counterclockwise rotation of the connecting plate 44. Finally, when the steel structure is welded, the fans 5 in the two bellows 2 rotate in opposite directions to create air convection, thereby absorbing the gas generated during welding.
