Description

Technical Field

[0001] This invention relates to the field of steel frame welding positioning technology, specifically to an auxiliary fixture for welding equipment for building support steel frames. Background Technology

[0002] In prefabricated building construction, steel frames serve as the main load-bearing components, ensuring the stability and safety of the building, providing a framework for the building, determining the shape and size of the internal space, and also serving as a supporting structure for the building's exterior. This facilitates the renovation and maintenance of the building. To accelerate the construction progress, steel frames in prefabricated building construction can be prefabricated in the factory and assembled on-site, improving construction efficiency.

[0003] The steel frame is assembled by welding multiple sets of vertical and horizontal steel members. During the welding process, the horizontal steel members need to be placed horizontally, and then multiple people need to work together to erect the vertical steel members one by one and adjust their positions to be perpendicular to the horizontal steel members before welding to form a fence-like steel frame. Due to the long length and heavy weight of the steel frame, manual handling is time-consuming and labor-intensive. At the same time, manual positioning and welding are prone to welding misalignment, resulting in low welding efficiency and significant operational safety risks. In addition, the welding slag generated cannot be cleaned, affecting subsequent welding work. Therefore, an auxiliary fixture for welding equipment for building support steel frames is proposed to solve this technical defect. Summary of the Invention

A centering clamping assembly is provided on both the front and rear sides of the placement platform.

[0007] The upper part of the placement platform has evenly distributed suction holes, and the placement platform is equipped with a dust collection component;

[0008] It also includes a support plate located at the middle of one end of the two mounting rails, a telescopic support rod on the left side of the support plate, an extension end on the other end of the telescopic support rod, the extension end passing through to the right side of the support plate and connected to a positioning plate, and an adjustment component for adjusting the movement of the positioning plate on the support plate.

[0009] Furthermore, the winding assembly includes a bidirectional output motor located at the middle of the upper end of the movable seat. The output shaft of the bidirectional output motor is provided with a rotating shaft that is connected to and rotates with the movable seat. A winding reel is fixed to the outside of the rotating shaft at the same center. The outside of the winding reel is wound and fixed with the pull rope.

[0010] The pull rope passes through the movable seat and the telescopic rod and is fixedly connected to the connecting seat.

[0011] Furthermore, the upper end of the clamping seat is provided with a placement groove, and when the telescopic rod is in the extended state, the lower surface of the connecting seat is aligned with the lower surface of the mounting track.

[0012] Furthermore, the lifting support assembly includes a hydraulic push rod five located at the bottom of the sliding seat. The push rod of the hydraulic push rod five passes through to the top of the sliding seat and connects to the placement platform. Telescopic support rods are provided between the placement platform and the four corners of the sliding seat.

[0013] Furthermore, the upper end of the placement platform is provided with a scale parallel to the loading seat, and the center of the side opening of the loading seat is provided with an indicator strip that contacts the upper surface of the scale.

[0015] Furthermore, the placement platform is provided with a sliding groove for the centering clamp to slide linearly near the loading seat.

[0016] Furthermore, the dust collection assembly includes a storage cylinder disposed on the side of the placement platform, a vacuum cleaner being connected to the side of the storage cylinder, an opening at the upper end of the storage cylinder, a cover being provided at the opening, and a flexible hose being connected between the cover and the upper surface of the placement platform.

[0017] Furthermore, the adjustment assembly includes a threaded cylinder located on the left side of the support plate, and a threaded adjustment rod that passes through the support plate and rotates in connection with the positioning plate is threadedly connected inside the threaded cylinder.

[0018] Furthermore, tilt sensors are provided at the four corners of the upper surface of the hoisting frame and the four corners of the upper surface of the placement platform, and an audible and visual alarm is provided on the side of the hoisting frame.

[0019] Compared with the prior art, the present invention provides an auxiliary fixture for welding equipment for building support steel frames, which has the following beneficial effects:

[0020] 1. The auxiliary clamp of the steel frame welding equipment for this building supports the release of the pull rope through the set winding component. The telescopic rod extends synchronously, driving the connecting seat to move straight down to the bottom. This makes it convenient for workers to place the horizontal members of the steel frame between the front clamp and the rear clamp. According to the length of the horizontal members of the steel frame, the clamp is moved by the hydraulic push rod 2 to clamp both ends of the horizontal members of the steel frame.

[0021] After the horizontal members of the steel frame are horizontally fixed, the loading seats are moved within the limiting mounting slots on the placement platform according to the distribution distance of the vertical members. This simultaneously moves the indicator strip on the scale, allowing the distance between the loading seats to be adjusted to correspond to the distance between the vertical members of the steel frame. After adjustment, the magnetic plate is energized to attract and fix the loading seats, allowing the vertical members of the steel frame to be placed horizontally within the loading seats. After placement, the clamping assembly clamps both ends of the vertical members, centering them within the loading seats. Simultaneously, four hydraulic pushers move the clamping plates, further centering the vertical members within the loading seats. After the components are installed, the positioning plate is moved by adjusting the telescopic support rod under the linear extension and retraction of the positioning plate. This limits the movement of the placement platform, ensuring that the sliding seat is moved within the track groove of the installation track by the hydraulic push rod three, simultaneously moving the placement platform. When the placement platform contacts the positioning plate, the lifting support assembly pushes the placement platform upward, and the hydraulic push rod one pushes the moving seat to move towards each other within the directional slide groove. This causes the fixed horizontal members of the steel frame to move and contact the fixed vertical members of the steel frame. The intersection of the vertical members and the corresponding horizontal members of the steel frame is the welding point, thus avoiding manual handling and ensuring stable welding, improving welding efficiency and operational safety, while also preventing welding displacement.

[0022] 2. The auxiliary fixture of the steel frame welding equipment for this building works through the dust collection component. By utilizing the interconnection between the dust collection component, the placement platform and the suction hole, the dust generated during welding is sucked in through the suction hole, which avoids welding slag splashing, polluting the environment and affecting subsequent welding work.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 5 An auxiliary fixture for welding steel frame for building support includes a hoisting frame 1, which is fixed above the working area to ensure its horizontal stability and serves as the main support structure of the entire device. The left and right side walls of the inner cavity are provided with directional sliding grooves 2. A pair of symmetrically positioned movable seats 3 slide between the directional sliding grooves 2 to guide the sliding of the movable seats 3. Hydraulic push rods 4 are installed and fixed on the front and rear sides of the hoisting frame 1, and the push rods are respectively connected and fixed to the movable seats 3 to drive the movable seats 3 to move along the directional sliding grooves 2.

[0035] Telescopic rods 5 are fixed on both the left and right sides of the lower surface of the movable seat 3. The other end of the telescopic rod 5 is connected to and fixed to a connecting seat 6. A hydraulic push rod 7 is installed and fixed on the outer surface of the connecting seat 6. A clamping seat 8 is fixed at the push rod. The clamping seats 8 on the front and rear sides are arranged opposite each other and are used to clamp the transverse members of the steel frame supporting the steel frame.

[0036] The movable seat 3 is equipped with a winding assembly, on which a pull rope 12 is provided. The pull rope 12 is connected to the telescopic rod 5, driving the telescopic rod 5 to extend and retract. The winding assembly includes a bidirectional output motor 9, a rotating shaft 10, and a winding reel 11. The bidirectional output motor 9 is mounted and fixed in the middle of the upper surface of the movable seat 3. A rotating shaft 10 connected to and rotating with the movable seat 3 is mounted and fixed at the output shaft of the bidirectional output motor 9. The winding reel 11 is fixed concentrically on the outside of the rotating shaft 10. The pull rope 12 is wound and fixed on the winding reel 11. The pull rope 12 passes through the movable seat 3 and the telescopic rod 5, and is connected and fixed to the upper surface of the connecting seat 6. By rotating the bidirectional output motor 9 in both directions, the pull rope 12 can be wound and unwound, thereby driving the telescopic rod 5 to extend and retract, and adjusting the height of the clamping seat 8.

[0037] The telescopic rod 5 is composed of a fixed outer cylinder and a movable inner rod that are slidably connected to each other. The ends of the fixed outer cylinder and the movable inner rod that are far apart from each other are respectively connected to the hoisting frame 1 and the connecting seat 6.

[0038] The mounting rail 13 is located below the hoisting frame 1 and is symmetrically distributed at the center. The upper end of the rail has a rail groove 14 for sliding the sliding seat 15. A hydraulic push rod 17 is installed and fixed between the right sides of the mounting rail 13. The push rod is connected and fixed to the sliding seat 15 and is used to drive the sliding seat 15 to move along the rail groove 14.

[0039] The upper end of the clamping seat 8 is provided with a placement groove for placing the transverse steel frame members that support the steel frame. When the telescopic rod 5 is in the extended state, the lower surface of the connecting seat 6 is aligned with the lower surface of the mounting rail 13, ensuring that the connecting seat 6 can be moved down to the ground for easy placement of the transverse steel frame members.

[0040] Please see Figures 6 to 9 The sliding seat 15 slides between the track grooves 14. The sliding seat 15 is provided with a lifting support assembly, including a hydraulic push rod 16 and a telescopic support rod 18. The hydraulic push rod 16 is installed and fixed on the bottom surface of the sliding seat 15. The push rod of the hydraulic push rod 16 passes through the top of the sliding seat 15 and is connected and fixed to the bottom of the placement platform 19, which is used to push the placement platform 19 to rise and fall. The telescopic support rod 18 is fixed between the four corners of the placement platform 19 and the sliding seat 15, which plays a supporting and guiding role. The telescopic support rod 18 is composed of an inner rod and an outer cylinder that slide together. The ends of the inner rod and the outer cylinder that are far apart from each other are connected to the placement platform 19 and the sliding seat 15 respectively.

[0041] The placement platform 19 is installed on the lifting support assembly, and a limiting installation groove 20 is opened through it in the left and right directions for sliding of multiple loading seats 22. The number of loading seats 22 is set according to the number of vertical members of the steel frame of the support steel frame to be assembled and welded. A magnetic suction plate 21 is fixed in the limiting installation groove 20, which contacts the lower surface of the fixed loading seat 22 for adsorbing the fixed loading seat 22. Suction holes 30 are evenly distributed on the upper surface of the placement platform 19 for connecting with the dust collection assembly to collect the dust generated during welding.

[0042] The mounting rail 13 is bolted to the ground, ensuring that the placement platform 19 is level.

[0043] The loading seat 22 has a U-shaped front and rear opening structure and slides within the limiting mounting groove 20. Hydraulic push rods 23 are fixed on both the left and right sides of the loading seat 22. Clamping plates 24 are fixed at the push rods and located inside the opening of the loading seat 22 for clamping the vertical members of the steel frame. An indicator strip 26 is fixed in the middle of the side opening of the loading seat 22. A scale 25 is fixed on the upper surface of the placement platform 19 and is parallel to the loading seat 22. The indicator strip 26 and the upper surface of the scale 25 are in contact and cooperate for observing and adjusting the distance between the loading seats 22.

[0044] The placement platform 19 is equipped with a centering clamping assembly on both the front and rear sides. The clamping assembly includes a hydraulic push rod 27 and a centering clamping plate 28. The hydraulic push rod 27 is installed and fixed in the middle of the front and rear sides of the placement platform 19. The push rod of the hydraulic push rod 27 is fixed with a centering clamping plate 28 that contacts the upper surface of the placement platform 19 and is arranged parallel to the loading seat 22. The upper surface of the placement platform 19 is provided with multiple sliding grooves 29 for the centering clamping plate 28 to slide linearly close to the loading seat 22. The push rod of the hydraulic push rod 27 pushes the centering clamping plate 28 to move in the sliding grooves 29, thereby achieving centering clamping of the vertical members of the steel frame.

[0045] The placement platform 19 is equipped with a dust collection component, which includes a dust collection cylinder 31, a vacuum cleaner 32, and a hose 33. The dust collection cylinder 31 is installed and fixed on the front surface of the placement platform 19, and the vacuum cleaner 32 is connected to its front surface. A filter screen is provided at the connection between the suction port of the vacuum cleaner 32 and the dust collection cylinder 31 to isolate welding slag and prevent it from entering the vacuum cleaner 32. The upper end of the dust collection cylinder 31 is open, and a cover is provided at the opening. The cover is connected to the upper surface of the placement platform 19 through the hose 33 to collect the dust generated during welding.

[0046] The support plate 34 is located in the middle between the left ends of the two mounting rails 13. A telescopic support rod 38 is fixed on its left side. The right end of the telescopic support rod 38 is a movable extension end. The extension end passes through to the right side of the support plate 34 and is connected to and fixed to a positioning plate 37. The support plate 34 is provided with an adjustment assembly, including a threaded cylinder 35 fixed to the left surface of the support plate 34. A threaded adjustment rod 36 that passes through the support plate 34 and is connected to and rotates with the positioning plate 37 is threadedly connected to the threaded cylinder 35.

[0047] The support plate 34 is fixed to the ground with bolts to ensure that it is perpendicular and horizontal to the ground.

[0048] Inclination sensors 39 are fixed at the four corners of the upper surface of the hoisting frame 1 and the four corners of the upper surface of the placement platform 19. An audible and visual alarm 40 is provided on the side of the hoisting frame 1. After the hoisting frame 1 and the placement platform 19 are installed horizontally, the inclination sensors 39 monitor the tilt angle. When the angle changes and the horizontal state is not reached, the signal is transmitted to the controller. The controller controls the audible and visual alarm 40 to sound and light an alarm, so that the operator can adjust and reinstall the horizontal state in time.

[0049] This equipment uses a PLC (Programmable Logic Controller) to centrally control hydraulic actuators, motors, and other equipment, thereby improving the level of automation in operation.

[0050] Working steps and principles:

[0051] The bidirectional output motor 9 drives the take-up reel 11 on the rotating shaft 10 to rotate, so that the take-up reel 11 releases the pull rope 12. When the pull rope 12 is released, the traction connecting seat 6 moves down, and the telescopic rod 5 extends synchronously, causing the connecting seat 6 to move straight down to the bottom, reducing the height of the clamping seat 8. This makes it easier for workers to place the transverse steel frame members between the front clamping seat 8 and the rear clamping seat 8 respectively. According to the length of the transverse steel frame members, the clamping seat 8 is moved by the hydraulic push rod 7 to clamp both ends of the transverse steel frame members.

[0052] After the horizontal members of the steel frame are fixed horizontally between the clamping seats 8, the loading seat 22 is moved within the limiting mounting groove 20 on the placement platform 19 according to the distribution distance of the vertical members of the steel frame. This simultaneously drives the indicator bar 26 to move on the scale 25. By observing the scale on the scale 25, the distance between each loading seat 22 is adjusted to correspond to the distance between the vertical members of the steel frame that are set to be installed.

[0053] After adjustment, the magnetic plate 21 is energized to attract and fix the loading seat 22, so that the vertical steel frame members can be placed horizontally in the loading seat 22. After placement, the hydraulic push rod 27 pushes the centering clamp 28 to move in the sliding groove 29, so that the centering clamp 28 moves towards each other to clamp the two ends of the vertical steel frame members, so that the vertical steel frame members are placed in the center in the loading seat 22.

[0054] Simultaneously, the hydraulic push rod 23 pushes the clamping plate 24 to move, thereby clamping the centrally placed vertical steel frame member in the loading seat 22. After the overall vertical steel frame member is installed, the threaded adjustment rod 36 is screwed into the threaded cylinder 35 by hand and rotated on the positioning plate 37. With the linear extension and retraction of the telescopic support rod 38 on the positioning plate 37, the positioning plate 37 is pushed to move, thereby limiting the movement of the placement platform 19.

[0055] After adjusting the limit, the sliding seat 15 is pushed to move in the track groove 14 of the mounting track 13 by the hydraulic push rod 3 17, which simultaneously drives the placement platform 19 to move, so that the placement platform 19 contacts the positioning plate 37. The placement platform 19 is pushed to move upward under the telescopic support of the telescopic support rod 18 by the hydraulic push rod 5 16, which adjusts the height of the fixed steel frame vertical members. The moving seat 3 is pushed to move towards each other in the directional slide 2 by the hydraulic push rod 1 4, which drives the fixed steel frame horizontal members to move and contact the fixed steel frame vertical members. The corresponding intersection position of the fixed steel frame vertical members and the steel frame horizontal members is the welding point, which realizes the positioning welding of the assembly connection point of the overall building support steel frame. This avoids manual handling and stable welding, improves welding efficiency and operational safety, and avoids welding displacement.

[0056] During the welding process, the vacuum cleaner 32 works to extract dust. By utilizing the interconnection between the vacuum cleaner 32, the storage cylinder 31, the hose 33, the placement platform 19, and the suction hole 30, the welding slag generated during welding is collected in the storage cylinder 31 through the suction hole 30, thus preventing welding slag from splashing and polluting the environment and affecting subsequent welding work.

[0057] By expanding the above structural principles and system control, the auxiliary fixture for the building support steel frame welding equipment of the present invention can realize automated positioning and clamping welding, ensure welding positioning accuracy, avoid welding deviation, greatly improve welding efficiency, and at the same time, realize the treatment of welding slag, achieving the goal of environmentally friendly welding.
