Description

Technical Field

[0001] This utility model relates to the technical field of steel structure production equipment, and in particular to a steel structure welding positioning device. Background Technology

[0002] In the construction of steel structures for large industrial plants, bridges, and large equipment, it is often necessary to weld various auxiliary supports onto the large and extra-long steel structure. These supports are used to install pipelines, equipment, and accessories. Currently, when adding supports to these large and extra-long steel structures, manual measurement and positioning using measuring tapes are the primary methods. However, this traditional measurement and positioning method has many drawbacks: low measurement efficiency: due to the large volume and extra-long length of the steel structure, manual measurement often requires multiple people, making the process cumbersome, time-consuming, and severely restricting the construction progress. Low measurement accuracy: manual operation is easily affected by environmental factors, personnel experience, and skill level, making it difficult to guarantee measurement accuracy. Furthermore, during the welding of supports, the operators manually assist in fixing the supports, leading to deviations or tilting during welding. This results in the supports not meeting design requirements after welding, requiring rework, which not only increases construction costs but may also affect the stability and safety of the overall structure.

[0003] Therefore, it is necessary to develop a steel structure welding positioning device to address the aforementioned defects. Utility Model Content

[0004] The purpose of this invention is to provide a steel structure welding positioning device that automatically detects the position information of the support to be processed through a displacement sensor and controls the movement of the moving wheels, replacing manual measurement, improving construction progress, and improving positioning accuracy by setting up positioning components.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model discloses a steel structure welding positioning device, comprising upright plates and a crossbeam. Two upright plates are arranged in parallel and vertically. The crossbeam is fixedly installed on the top surface of the upright plates. Four movable wheels are provided at the lower end of the upright plates and are evenly fixed on the lower end surfaces of the two sides of the upright plates. The lower end of the crossbeam is provided with positioning components. Two sets of positioning components are provided and symmetrically arranged on both sides of the upright plates. The positioning components are driven to move relative to each other by a drive component to clamp and position the workpiece to be processed. Displacement sensors are installed at the center of the lower end surface of the crossbeam and at the lower inner sides of the two upright plates. The device also includes a controller, which is electrically connected to the displacement sensors, the drive components, and the drive motors of the movable wheels, and is used to control the operation of the drive components and the movement of the device according to the detection signals of the displacement sensors.

[0007] Preferably, the positioning assembly includes a fixed plate, a first electric telescopic rod, a crossbar, and a movable rod. The fixed plate has an L-shaped structure. The first electric telescopic rod is horizontally arranged and its back is fixed to the vertical side of the fixed plate. The output end of the first electric telescopic rod is fixedly connected to the crossbar. Movable rods are provided on both sides of the crossbar. One end of the movable rod is hinged to the crossbar, and the other end of the movable rod is rotatably connected to a clamping post. A through hole is provided in the middle of the movable rod, and a rotating shaft is rotatably installed in the through hole. The rotating shaft is vertically fixed to the horizontal side of the fixed plate.

[0008] Preferably, the system further includes a positioning plate disposed at the front end of the crossbar. The positioning plate is connected to the crossbar by at least two guide posts, which are symmetrically distributed on the upper and lower sides of the crossbar. The front end of each guide post is fixed to the positioning plate, and the rear end of each guide post passes through the crossbar and is slidably connected to it. A spring is sleeved on the outer circumference of each guide post, and the spring is placed between the positioning plate and the crossbar.

[0009] Preferably, the drive assembly includes a bidirectional lead screw, a first motor, a slider, and a second electric telescopic rod. The bidirectional lead screw is rotatably mounted on the lower end of the crossbeam. The lower end of the crossbeam is provided with a sliding groove. The slider is mounted on the bidirectional lead screw and is slidably connected to the sliding groove. The slider is threadedly connected to the bidirectional lead screw. One end of the bidirectional lead screw extends out of the crossbeam and is fixedly mounted on the output shaft of the first motor. The lower end of the slider is fixedly connected to the second electric telescopic rod, and the output end of the second electric telescopic rod is fixedly connected to the upper surface of the vertical side of the fixed plate.

[0010] Preferably, a rubber sleeve is provided around the outer periphery of the clamping column, and a rubber pad is attached to the front end of the positioning plate.

[0011] Preferably, the moving wheel includes two driving wheels respectively installed at the front ends of the upright plates on both sides, two driven wheels located at the rear ends of the upright plates, and two drive motors. The two drive motors are respectively connected to the driving wheels on both sides through a transmission device. The drive motors are electrically connected to the controller and are used to drive the driving wheels to rotate so as to realize the movement of the device.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0013] This utility model relates to a steel structure welding positioning device. A controller drives moving wheels equipped with a drive motor, eliminating the need for manual handling. Displacement sensors automatically detect the position of the support to be processed, and the controller directly drives the positioning component, replacing the cumbersome process of manual measurement with a measuring tape and multiple people working together for positioning. This significantly shortens positioning time and effectively improves construction progress. The positioning component uses two sets of symmetrically arranged clamping structures to stably clamp the support to be welded, replacing manual assistance in fixing and avoiding positional deviations or tilting caused by unstable fixing during welding. Simultaneously, the spring-buffered design of the positioning plate reduces damage to parts caused by excessive clamping, further ensuring the accuracy of the support's position after welding, significantly reducing rework rates, and thus lowering construction costs. The movable rod and clamping column structure of the positioning component can adapt to supports of different sizes, demonstrating strong versatility. Attached Figure Description

[0019] The core of this utility model is to provide a steel structure welding positioning device, which automatically detects the position information of the support to be processed through a displacement sensor and controls the movement of the moving wheels, replacing manual measurement, improving the construction progress, and the setting of positioning components improves the positioning accuracy.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Refer to the attached diagram. Figure 1 This is a three-dimensional structural diagram of the steel structure welding positioning device of this utility model; Figure 2 This is a three-dimensional structural diagram of the positioning component and driving component of this utility model; Figure 3 This is a schematic diagram of the three-dimensional structure of the positioning component.

[0023] In one specific implementation, such as Figures 1-3 As shown, a steel structure welding positioning device includes two vertical plates 1 and two horizontal beams 2. The vertical plates 1 are arranged in parallel and vertically, with the horizontal beams 2 fixedly mounted on their top surfaces. Four movable wheels 3 are evenly fixed to the lower surfaces of the two vertical plates 1. Each movable wheel 3 includes two driving wheels 301 mounted at the front ends of the two vertical plates 1, two driven wheels 302 located at the rear ends of the vertical plates 1, and a drive motor 303. The driving wheels 301 are connected to the drive motors 303 via a transmission device. The drive motors 303 are electrically connected to a controller 7 and are used to drive the driving wheels 301 to rotate, thus moving the device. The two driving wheels 301 are controlled by independent drive motors 303, and both drive motors 303 are electrically connected to the controller 7. The controller 7 can simultaneously control the drive motors 303 on both sides to make the driving wheels 301 work simultaneously. Furthermore, the drive motor 303 and the drive wheel 301 are connected by a transmission device, which is not shown in the figure. The movable wheel 3 in the structure is existing technology and can be purchased on the market. It is not explained in detail here. The movable wheel 3 of the corresponding specification can be selected according to the size of the device.

[0024] In one specific implementation, such as Figures 1-3As shown, the lower end of the crossbeam 2 is provided with a positioning assembly 4. There are two sets of positioning assemblies 4, which are symmetrically arranged on both sides of the vertical plate 1. The positioning assembly 4 is driven to move relative to each other by the drive assembly 5 to clamp and position the workpiece to be processed. The positioning assembly 4 includes a fixed plate 401, a first electric telescopic rod 402, a crossbar 403, and a movable rod 404. The fixed plate 401 has an L-shaped structure. The first electric telescopic rod 402 is horizontally arranged and its back is fixed to the vertical side of the fixed plate 401. The output end of the first electric telescopic rod 402 is fixedly connected to the crossbar 403. Movable rods 404 are provided on both sides of the crossbar 403. One end of the movable rod 404 is hinged to the crossbar 403, and the other end of the movable rod 404 is rotatably connected to a clamping column 406. The middle of the movable rod 404 is provided with a through hole, and a rotating shaft 405 is rotatably installed in the through hole. The rotating shaft 405 is vertically fixed to the horizontal side of the fixed plate 401. The first electric telescopic rod 402 outputs linear driving force, which is transmitted to the movable rod 404 through the crossbar 403. The movable rod 404 forms a lever structure with the pivot 405 as the fulcrum. When the first electric telescopic rod 402 extends, the crossbar 403 pushes one end of the movable rod 404 to move outward, and the other end of the movable rod 404 is connected to one side of the clamping column 406 to rotate inward, thereby achieving clamping. When the first electric telescopic rod 402 shortens, the crossbar 403 pulls one end of the movable rod 404 to move inward, and the clamping column 406 rotates outward, thereby achieving release.

[0025] The system also includes a positioning plate 407, which is positioned at the front end of the crossbar 403. The positioning plate 407 and the crossbar 403 are connected by at least two guide posts 408, which are symmetrically distributed on the upper and lower sides of the crossbar 403. The front end of each guide post 408 is fixed to the positioning plate 407, and the rear end of each guide post 408 passes through the crossbar 403 and is slidably connected to it. A spring 409 is fitted on the outer circumference of each guide post 408 and is positioned between the positioning plate 407 and the crossbar 403. The positioning plate 407 is slidably connected to the crossbar 403 via the guide posts 408. When the spring 409 is in its natural state, the front end of the positioning plate 407 extends beyond the front end of the clamping post 406, ensuring that the positioning plate 407 contacts the part first before clamping. The spring 409 is compressed, generating elastic force, thus achieving pre-positioning while avoiding rigid impact. Two sets of positioning components 4 are symmetrically distributed on both sides of the upright plate 1. The controller 7 synchronously controls the movement of the electric telescopic rods on both sides to ensure that the clamping forces are equal in magnitude and opposite in direction, thus preventing the parts from shifting due to force.

[0026] In one specific implementation, such as Figures 1-3As shown, the drive assembly 5 includes a bidirectional lead screw 501, a first motor 502, a slider 503, and a second electric telescopic rod 504. The bidirectional lead screw 501 is rotatably mounted on the lower end of the crossbeam 2. The lower end of the crossbeam 2 has a groove. The slider 503 is mounted on the bidirectional lead screw 501, and the slider 503 is fitted onto the bidirectional lead screw 501 and slidably connected to the groove. The slider 503 is threadedly connected to the bidirectional lead screw 501. One end of the bidirectional lead screw 501 extends out of the crossbeam 2 and is fixedly mounted on the output shaft of the first motor 502. The first motor 502 drives the bidirectional lead screw 501 to rotate, and the slider 503 rotates with the bidirectional lead screw 501. The groove at the lower end of the crossbeam 2 engages with the slider 503, causing the slider 503 to translate along the length of the crossbeam 2, thus improving the stability of the lateral movement of the positioning assembly 4. The lower end of the slider 503 is fixedly connected to the second electric telescopic rod 504, and the output end of the second electric telescopic rod 504 is fixedly connected to the upper surface of the vertical side of the fixed plate 401.

[0027] In one specific implementation, such as Figures 1-3 As shown, a displacement sensor 6 is installed at the center of the lower end face of the crossbeam 2 to detect the longitudinal position of the support to be processed. Displacement sensors 6 are also installed at the lower inner ends of the two side uprights 1. These sensors detect the lateral distance between the device and the steel structure, ensuring the device is centered and preventing support misalignment. A controller 7 is also included, which is electrically connected to both the displacement sensors 6 and the drive assembly 5, and controls the drive assembly 5 to operate based on the detection signals from the displacement sensors 6.

[0028] In one specific implementation, such as Figures 1-3 As shown, a rubber sleeve is fitted around the outer periphery of the clamping column 406, and a rubber pad is attached to the front end of the positioning plate 407. The rubber sleeve and rubber pad can increase the friction between the clamping column 406, the positioning plate 407 and the bracket, prevent the bracket from sliding during welding, and at the same time buffer the clamping force to prevent damage to the bracket surface.

[0029] The operation of this utility model steel structure welding positioning device is as follows: During operation, the operator issues a command through the controller 7, which starts the drive motor 303. The driving wheel 301 rotates under the drive of the transmission device, and the driven wheel 302 rotates accordingly. The moving wheel 3 moves the entire device to the vicinity of the corresponding position on the steel structure to be welded. The displacement sensor 6 at the center of the lower end face of the crossbeam 2 detects the longitudinal position of the support to be processed (along the length of the steel structure) in real time and transmits the data to the controller 7. The displacement sensors 6 at the lower inner ends of the two upright plates 1 detect the lateral distance between the device and the two sides of the steel structure. If the distances on both sides are unequal, the controller 7 controls the drive motors 303 on both sides to rotate, adjusting the device to the centered position. Based on the longitudinal position data fed back by the displacement sensors 6, the controller 7 controls the drive motors 303 to stop rotating, completing the precise positioning of the device. The first motor 502 is started, driving the bidirectional lead screw 501 to rotate. Since the slider 503 is threadedly connected to the bidirectional lead screw 501 and restricted by the sliding groove, the two sets of sliders 503 move relative to each other along the bidirectional lead screw 501 until the positioning component 4 reaches the corresponding lateral position of the bracket to be clamped, at which point the first motor 502 stops. The controller 7 controls the extension and retraction of the second electric telescopic rod 504, causing the fixing plate 401 and the structure below to move up and down, aligning the clamping column 406 with the clamping point of the bracket to be processed, at which point the second electric telescopic rod 504 stops. The first electric telescopic rod 402 is then started to extend and retract, pushing the crossbar 403 to move. The crossbar 403 drives the movable rod 404 to rotate around the pivot 405, causing the clamping column 406 at the other end of the movable rod 404 to clamp and fix the bracket to be processed. During clamping, the positioning plate 407 contacts the bracket to be processed, the guide column 408 slides within the crossbar 403, and the spring 409 acts as a buffer to prevent excessive clamping and damage to the parts. After welding is completed, controller 7 controls each component to reset, releases the clamp on the bracket, and the device can move to the next welding position for operation.

Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
