Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an adjustable temporary support fixture system for welding irregular steel structures. Background Technology

[0002] In building construction, irregular steel structures are complex in shape, making positioning and support during welding difficult. Traditional fixed supports are insufficient to meet the needs of varied structures. Therefore, an adjustable temporary support fixture system for welding irregular steel structures is established. This system can be flexibly adjusted according to the shape, size, and welding position of different irregular components, providing precise and stable temporary support for the welding process. This ensures that the components remain in the correct position during welding, improves welding accuracy and construction efficiency, and guarantees the smooth progress of welding operations for irregular steel structures.

[0003] The existing devices still have the following shortcomings: In order to improve the movement efficiency, existing devices are generally equipped with locking casters at the bottom. However, when the device supports a steel structure, the locking structure of the casters is difficult to completely restrict the rolling and swaying of the wheels under large loads or complex forces. In addition, the contact area between the locking casters and the ground is limited and the support rigidity is insufficient. This leads to the problem of unstable support of the locking casters after the device supports the steel structure. This can easily cause the support position to shift, affecting the accuracy and stability of the steel structure welding, and may even cause safety hazards. Utility Model Content

[0004] This utility model provides an adjustable temporary support fixture system for welding irregular steel structures, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] Embodiments of this utility model provide an adjustable temporary support fixture system for welding irregularly shaped steel structures, including a hydraulic telescopic cylinder, and further comprising:

[0007] The base is fixed to the bottom end of the hydraulic telescopic cylinder, and locking casters are installed at the four corners of the bottom end of the base.

[0008] A support structure is provided on both sides of the base. The support structure includes a movable arm, which is rotatably connected to both sides of the base. A hydraulic support cylinder is installed inside the movable arm at the end away from the base, and a rubber pad is installed at the telescopic end of the hydraulic support cylinder.

[0009] A ball seat is installed at the telescopic end of a hydraulic telescopic cylinder, and a mounting bracket is provided at the top of the ball seat. A locking screw is connected to the internal thread on one side of the mounting bracket, and a crank is fixed to one side of the locking screw.

[0010] The positioning structure, located at the top of the mounting bracket, is used to form a corresponding arc-shaped constraint surface according to the shape of the steel structure.

[0011] With the above technical solution, the tooling can be flexibly moved to the designated position by locking the casters. After reaching the position, the support structure and support device prevent the device from shifting during the welding process. The hydraulic telescopic cylinder extends and drives the mounting frame to move up and down. The support height is adjusted to place the steel structure on the top of the mounting frame. The crank handle is turned to make the locking screw press against the steel structure.

[0012] Furthermore, the ball seat is internally rotatably connected to a rotating ball head, which is connected to the mounting bracket by bolts. A hand-tightening bolt is internally threaded on one side of the ball seat. A reinforcing bracket connected to the base is fixed to the outside of the hydraulic telescopic cylinder. A push handle is installed on one side of the top of the base. A shock-absorbing pad is fixed to the top of the mounting bracket.

[0013] Through the above technical solution, the rotational connection between the ball seat and the rotating ball head allows the mounting frame to adjust its angle within a certain range, better fitting the steel structure. The reinforcement frame enhances the connection stability between the hydraulic telescopic cylinder and the base, while the shock-absorbing pad can buffer vibrations during support, thus providing a reliable support foundation for the steel structure.

[0014] Furthermore, a transmission frame is rotatably connected to one side of the bottom end of the moving arm, and a dual-output shaft motor is installed at the bottom end of the base. A second lead screw is installed at the end of the output shaft of the dual-output shaft motor, and a moving block is threaded to the outer side of the second lead screw.

[0015] The above technical solution involves starting a dual-output shaft motor to drive two sets of second lead screws to rotate synchronously, causing the moving block to extend the moving arm via the transmission frame. Then, the hydraulic support cylinder pushes the rubber pad to fit tightly against the ground, providing stable support force and improving the reliability and adaptability of the support to a certain extent.

[0016] Furthermore, the moving block and the transmission frame form a rotating structure, and the second lead screw is mounted on both sides of the bottom end of the base through bearing seats.

[0017] Through the above technical solution, the rotating structure between the moving block and the transmission frame, together with the second lead screw installed on both sides of the bottom end of the base via bearing seats, allows the moving block to move smoothly along the lead screw when the dual output shaft motor drives the second lead screw to rotate. At the same time, the transmission frame drives the moving arm to rotate, realizing flexible adjustment of the position of the moving arm.

[0018] Furthermore, the second lead screw is provided in two sets, and the two sets of the second lead screw are symmetrically distributed on the vertical center line of the dual output shaft motor, and the directions of the external threads on the surfaces of the two sets of the second lead screw are opposite.

[0019] Through the above technical solution, two sets of symmetrically distributed second lead screws with opposite external thread directions can enable the moving blocks on both sides to move synchronously in opposite directions under the drive of a dual-output shaft motor. The moving arms are driven to open and close symmetrically through the transmission frame, ensuring the balance of the support structure during the adjustment process.

[0020] Furthermore, the positioning structure includes a stop rod, which is rotatably connected to both sides of the top end of the mounting frame. A guide rod is fixed to the bottom end of the mounting frame. A movable seat is slidably connected to the outer side of the guide rod. A movable rod is fixed to the top end of the movable seat. A first lead screw is threaded into the interior of the movable seat. A handle is fixed to one side of the first lead screw.

[0021] By rotating the handle, the first lead screw drives the moving seat to slide along the guide rod, while the moving rod moves, adjusting the distance and positional relationship between the moving rod and the stop rods on both sides, forming an arc-shaped constraint surface that matches the curvature of the steel structure.

[0022] Furthermore, the movable rod extends to the bottom end of the mounting bracket and connects to the movable seat, and the stop rods are symmetrically distributed on the vertical center line of the movable rod.

[0023] Through the above technical solution, the moving rod is connected to the moving seat and can be precisely adjusted in position as the moving seat moves. With the symmetrically distributed stop rods, an arc-shaped constraint surface that adapts to steel structures with different curvatures can be quickly formed to achieve stable positioning of the steel structure.

[0024] The above-described solution of this utility model has at least the following beneficial effects:

[0025] 1. This utility model, by starting a dual-output shaft motor to drive two sets of second lead screws to rotate synchronously, causes the moving block to drive the moving arm to unfold through the transmission frame. Then, the hydraulic support cylinder pushes the rubber pad to fit tightly against the ground, thereby realizing the automatic support function of this device. This avoids the shaking caused by the universal wheel due to locking failure or small contact area, effectively reducing the safety risks caused by unstable support, providing reliable temporary support for the welding of irregular steel structures, and ensuring the positioning accuracy of the steel structure.

[0026] 2. In this utility model, by rotating the handle, the first lead screw drives the moving seat to slide along the guide rod. At the same time, the moving rod moves, adjusting the distance and position relationship between the moving rod and the two side stop rods, forming an arc-shaped constraint surface that matches the curvature of the steel structure, accurately fitting the outline of the component, avoiding the problem of poor adaptability caused by a single fixed curvature, and enabling the fixture to quickly fix various irregular structures.

[0033] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0034] like Figures 1 to 4 As shown, an embodiment of this utility model provides an adjustable temporary support fixture system for welding irregularly shaped steel structures, including a hydraulic telescopic cylinder 1, and further comprising:

[0035] The base 11 is fixed to the bottom end of the hydraulic telescopic cylinder 1, and locking casters 12 are installed at the four corners of the bottom end of the base 11.

[0036] Support structure 9 is provided on both sides of base 11. Support structure 9 includes movable arm 901, which is rotatably connected to both sides of base 11. Hydraulic support cylinder 902 is installed inside the movable arm 901 at the end away from base 11. Rubber pad 903 is installed at the telescopic end of hydraulic support cylinder 902.

[0037] Ball seat 3 is installed at the telescopic end of hydraulic telescopic cylinder 1, and a mounting bracket 5 is provided at the top of ball seat 3. A locking screw 6 is connected to the internal thread on one side of the mounting bracket 5, and a crank handle 7 is fixed on one side of the locking screw 6.

[0038] Positioning structure 4 is set at the top of mounting bracket 5 and is used to form a corresponding arc-shaped constraint surface according to the shape of the steel structure;

[0039] The ball seat 3 is internally connected to a rotating ball head 14, which is connected to the mounting bracket 5 by bolts. A hand-tightening bolt 13 is internally threaded on one side of the ball seat 3. A reinforcing bracket 10 connected to the base 11 is fixed on the outside of the hydraulic telescopic cylinder 1. A push handle 8 is installed on one side of the top of the base 11. A shock-absorbing pad 2 is fixed on the top of the mounting bracket 5.

[0040] In this embodiment of the utility model, the tooling can be flexibly moved to the designated position by the locking caster 12 at the bottom of the base 11. After reaching the position, the locking caster 12 is used to initially lock the position of the device. Then, the support structure 9 replaces the locking caster 12 to support the device and prevent the device from shifting during the welding process. Next, the hydraulic telescopic cylinder 1 extends and drives the mounting frame 5 to move up and down through the ball seat 3 to adjust the support height to match the installation height of the steel structure. At the same time, the rotational connection between the ball seat 3 and the rotating ball head 14 allows the mounting frame 5 to adjust its angle within a certain range to better fit the steel structure. The steel structure is placed on the top of the mounting frame 5 and contacts the shock-absorbing pad 2. The crank handle 7 is turned to make the locking screw 6 abut against the steel structure, and the positioning structure 4 clamps the position of the steel structure. The reinforcement frame 10 enhances the connection stability between the hydraulic telescopic cylinder 1 and the base 11, and the shock-absorbing pad 2 can buffer vibration during support, thereby providing a reliable support foundation for the steel structure.

[0041] like Figures 1 to 2 As shown, a transmission frame 904 is rotatably connected to one side of the bottom end of the moving arm 901. A dual-output shaft motor 907 is installed at the bottom end of the base 11. A second lead screw 906 is installed at the end of the output shaft of the dual-output shaft motor 907. A moving block 905 is threaded to the outer side of the second lead screw 906. The moving block 905 and the transmission frame 904 form a rotating structure. The second lead screw 906 is installed on both sides of the bottom end of the base 11 through bearing seats. There are two sets of second lead screws 906. The two sets of second lead screws 906 are symmetrically distributed on the vertical center line of the dual-output shaft motor 907. The directions of the external threads on the surfaces of the two sets of second lead screws 906 are opposite.

[0042] In this embodiment of the utility model, during support, the dual-output shaft motor 907 is started, and its dual output shafts drive the two sets of second lead screws 906 to rotate synchronously. Since the external threads of the two sets of second lead screws 906 are in opposite directions, the outer moving block 905 moves in the opposite direction along the second lead screw 906. The movement of the moving block 905 drives the moving arm 901 to rotate around the connection point with the base 11 through the transmission frame 904, so that the moving arm 901 unfolds outward, expanding the footprint of the device and lowering the center of gravity of the device. Then, the hydraulic support cylinder 902 is controlled to extend and retract, and its extension end extends, so that the rubber pad 903 is tightly attached to the ground, providing stable support force and improving the reliability and adaptability of the support to a certain extent.

[0043] like Figures 1 to 4 As shown, the positioning structure 4 includes a stop rod 401, which is rotatably connected to both sides of the top of the mounting bracket 5. A guide rod 404 is fixed to the bottom of the mounting bracket 5. A movable seat 403 is slidably connected to the outer side of the guide rod 404. A movable rod 402 is fixed to the top of the movable seat 403. A first lead screw 406 is threadedly connected to the inside of the movable seat 403. A handle 405 is fixed to one side of the first lead screw 406. The movable rod 402 extends to the bottom of the mounting bracket 5 and connects with the movable seat 403. The stop rods 401 are symmetrically distributed on the vertical center line of the movable rod 402.

[0044] In this embodiment of the invention, when positioning the steel structure, the first lead screw 406 is rotated by rotating the handle 405, causing the movable seat 403 to slide along the guide rod 404 through thread engagement. At the same time, the movable seat 403 drives the movable rod 402 to move, thereby adjusting the distance and positional relationship between the movable rod 402 and the two side stop rods 401, forming an arc-shaped constraint surface that matches the curvature of the steel structure. After the steel structure is placed on the positioning structure 4, the stop rods 401 and the movable rods 402 together limit and fix the steel structure, keeping it stable during welding, avoiding displacement, ensuring accurate positioning and stable support of the steel structure, and improving welding accuracy and quality.

[0045] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
