Description

Technical Field

[0001] The invention relates to the technical field of steel template welding, in particular to a steel template welding assembly lifting platform with an automatic alignment mechanism. Background Art

[0002] The structural design of the steel formwork directly affects its strength, rigidity, stability and reusability. It is usually composed of the following core parts: panels, frames, reinforcing ribs and connection systems. To improve overall welding efficiency and move away from manual arc welding, robotic arm-assisted welding is often used in combination with semi-automatic welding methods with manual positioning. According to the invention patent "Stainless Steel Formwork Welding Tooling" with publication number CN112846627B, an assembly area is set on the operating platform, and a fixed frame, side clamping mechanism, end clamping mechanism, top clamping mechanism and rib limiting components are set around the assembly area. The overall positioning of the steel formwork is perfect, but a lot of time is wasted in the early positioning of the steel formwork, resulting in an increase in the welding time of a single steel formwork.

[0003] At the same time, in the field of steel formwork welding technology, traditional semi-automatic welding positioning tooling has significant shortcomings: first, the position of the fixture needs to be frequently adjusted manually according to the size of the steel formwork, which is cumbersome and inefficient;

[0004] Secondly, the reinforcement ribs and frames need to be manually assembled and fixed before welding, which can easily cause the plates to shake or become unclamped during welding due to unstable clamping, affecting the weld quality.

[0005] Third, the longitudinal and transverse ribs are not dynamically compressed during welding, which can easily lead to weld fracture or deformation due to insufficient stress release. In addition, most existing equipment is designed for a single station and is difficult to adapt to large-scale construction needs.

[0006] To this end, we propose a steel formwork welding assembly lifting platform with an automatic alignment mechanism. Summary of the Invention

[0007] The purpose of the present invention is to provide a steel formwork welding assembly lifting platform with an automatic alignment mechanism to solve the problems raised in the above background technology;

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a steel template welding assembly lifting platform with an automatic alignment mechanism, comprising a slide, a lifting adjustment mechanism installed on the top of the slide, the lifting adjustment mechanism comprising a movable frame and a fixed frame, the movable frame and the fixed frame are slidably connected to a limit block in the inner groove, and the limit block is fixedly connected to a transmission box 1 on one side;

[0009] One side of the transmission box is movably connected to a sleeve disc through a bearing sleeve, and a splint assembly is slidably connected to the side track of the sleeve disc. The splint assemblies on both sides are clamped and fixed with sleeve plate assemblies in the gap. Telescopic shafts are symmetrically installed on the sleeve discs on both sides and on the top of the sleeve plate assemblies. Toothed sleeve rods are symmetrically installed on the sleeve discs on both sides. The sleeve plate assembly includes a plate sleeve and a straight plate, and the straight plate and the plate sleeve are slidably connected. The straight plate and the plate sleeve on the sleeve plate assembly are fixed with positioning sheet metal by bolts.

[0010] Furthermore, the lifting and adjusting mechanism also includes a drive shaft, and the drive shaft is movably connected to the inner wall of the groove on the movable frame and the fixed frame, and the drive shaft is fixed to the output end of the motor installed on the top of the movable frame and the fixed frame. One end of the drive shaft on both sides passes through the limit block and is movably connected to the bottom of the movable frame and the fixed frame through a bearing.

[0011] Furthermore, a clamping plate assembly is installed on the sleeve disc side, and the clamping plate assembly includes a slide and a fixed frame. A cylinder installed on the sleeve disc side drives the slide to move, so that the slide and the fixed frame clamp both sides of the sleeve plate assembly.

[0012] Furthermore, a skateboard is slidably connected to the telescopic shaft, and a rotating shaft 1 is movably connected on both sides of the skateboard. A turntable is fixed on the rotating shaft 1, and a tilting rod group is symmetrically installed on the top of the skateboard and on both sides of the turntable, and the single-sided tilting rod group is divided into an outer rod and an inner rod, which are in contact with the outer wall of one side of the turntable through a movable shaft.

[0013] Furthermore, a second rotating shaft is movably connected to the slide plate and is located on one side of the rotating shaft, and the gears at the ends of the second rotating shaft are engaged with the fixed gear sleeved on the first rotating shaft. The other end of the second rotating shaft passes through the through groove on the sleeve plate assembly and is sleeved with a driving tooth, and the driving tooth is engaged with the toothed sleeve rods on both sides.

[0014] Furthermore, a positioning frame is fixedly mounted on the skateboard, and pressure bar assemblies are slidably connected to both sides of the bottom of the positioning frame. A pad is slidably connected to the positioning frame, and both sides of the pad abut against the side walls of the tilting rod group.

[0015] The adjustment method of the steel template welding assembly lifting platform with automatic alignment mechanism is as follows:

[0016] Position the sheet metal assembly and install the top positioning sheet metal of the upper plate sleeve according to the size of the welded steel template. The top sheet metal forms a 90° angle to abut the side ribs and side walls. The motor on the top of the movable frame drives the entire straight plate to move toward the plate sleeve, automatically completing the compression and locking of the side ribs and side walls on both sides.

[0017] The longitudinal and transverse ribs are compressed and welded, and the longitudinal and transverse rib flat steels are plugged in according to the U-shaped slot, keeping them perpendicular to the inner wall of the side ribs. The second motor in the drive box is driven to work, and the two toothed sleeves are controlled to rotate in the same direction. The gears at the two ends of the drive shaft move between the toothed sleeves, and the slide is pushed to move synchronously. The intersection area of ​​the longitudinal and transverse ribs is used as the control point. After the control point is acquired as the lens at the bottom of the slide moves horizontally, the entire slide is driven to move to the control point side through the external controller. At the same time, the two toothed sleeves rotate in opposite directions, driving the entire shaft to rotate. The turntable rotates to push the end of the tilting rod group downward, moving the pressure strip assembly to the top of the longitudinal and transverse ribs and implementing the compression action, and cooperating with the welding robot arm on the slide side to automatically weld the steel template.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention utilizes a dynamic compression and deformation prevention structure, a toothed sleeve driving a sliding plate and a linkage mechanism of the tilting bar group, cooperates with a mechanical arm for regional positioning welding, and automatically positions and presses. Compared with step-by-step fixation and welding, the adjustment is flexible and the positioning welding efficiency is high. A transmission box 2 is used to control the steering of the toothed sleeves on both sides, the position of the sliding plate is adjusted in the same direction, and the turntable is controlled to rotate in different directions, thereby realizing the position adjustment of the end of the tilting bar group, controlling the pressure strip assembly to press the longitudinal and transverse ribs on the top of the steel template in real time, and the positioning fixture structure of vertical welding and vertical separation, compared with the overall fixation and overall separation fixture setting, the overall efficiency of the subsequent steel template is improved. At the same time, the longitudinal and transverse rib intersection area is welded, and the welding mechanical arm is coordinated for synchronous operation, which effectively eliminates welding stress and avoids weld fracture or plate deformation.

[0020] For steel formworks of different sizes and thicknesses, the telescopic sleeve assembly cooperates with the pads to adjust the position on the positioning frame, automatically adapting to the size of the steel formwork, and the steel formwork welding assembly lifting platform has high adaptability;

[0021] In the present invention, the double-station sleeve assembly design supports the simultaneous welding of two steel formworks, which significantly improves the overall construction efficiency. At the same time, the lifting adjustment mechanism is linked with the limit block, combined with the retractable sleeve assembly and positioning sheet metal, to achieve rapid and automatic positioning and tightening of the steel formwork frame, reducing manual intervention. The sleeve assembly and transmission components adopt a detachable structure, which is convenient for equipment storage and maintenance, while reducing transportation and storage costs.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-6 , the present invention provides a technical solution:

[0031] Example 1: The structural design of the steel formwork directly affects its strength, rigidity, stability and reusability. It is usually composed of the following core parts: panel, frame, reinforcement ribs and connection system. In order to improve the overall welding efficiency and get rid of manual arc welding, such as Figure 1 As shown, a steel template welding assembly lifting platform with an automatic alignment mechanism is used to adapt to the automatic welding of the robotic arm;

[0032] Compared with the traditional semi-automatic welding positioning tooling, which needs to be frequently adjusted according to the size of the steel template, and due to the assembly of the reinforcement ribs and the frame before welding, a clamp is set for locking to improve the quality and accuracy of the steel template welding. At the same time, the stress of the plate parts in the steel template assembly process is not directly welded without clamping, which is prone to weld fracture problems. This application is installed on the steel template welding assembly lifting platform with a clamping mechanism, and cooperates with the robot arm welding for real-time positioning adjustment, which is highly flexible. Figure 5As shown, the lifting adjustment mechanism 2 is located on the slide 1 and is divided into a movable frame 201 and a fixed frame 202. The position of the movable frame 201 is automatically adjusted according to the size of the steel template, and the steel template is placed on the top of the sleeve assembly 8 and is divided into two sides. The two steel templates can be welded at the same time. The double-station design improves the overall welding efficiency.

[0033] By utilizing the retractable characteristics of the sleeve assembly 8, the positioning sheet metal is fixed to the top of the sleeve of the sleeve assembly 8 to position the steel template frame. In conjunction with the movement of the movable frame 201 on the top of the upper slide 1, the gradually approaching plate surface block performs unilateral extrusion and fixation of the steel template frame to complete the automatic alignment work. As for the position adjustment of the movable frame 201 on the top of the slide 1, the gear at the bottom of the movable frame 201 is engaged with the rack on the side wall of the slide 1, and the entire movable frame 201 is driven to slide by the rotation of the gear.

[0034] After positioning is completed, the longitudinal and transverse ribs on the inner side of the steel formwork frame, that is, the reinforcement ribs, are welded. The installation of longitudinal and transverse ribs improves the bending resistance of the panel and reduces deformation. Secondly, the longitudinal and transverse ribs are connected in a plug-in manner, and U-shaped grooves are opened on the longitudinal and transverse bars on one side. After being clipped together, the whole is fixed to the frame. The position is adjusted by hammering to ensure that it is perpendicular to the inner wall of the frame.

[0035] The telescopic shaft 5 installed on the sleeve disc 4 on both sides has a controllable length, and a slide plate 10 is sleeved on the telescopic shaft 5. The inner side of the slide plate 10 is movably connected with a rotating shaft 11, and a turntable 12 is sleeved and fixed on the rotating shaft 11. However, the center of the turntable 12 does not coincide with the center of the cross section of the rotating shaft 11. Instead, like an eccentric wheel, the turntable 12 is driven to move in the middle of the slide plate 10 by the rotation of the rotating shaft 11. At the same time, a gear is sleeved and fixed on the rotating shaft 11 and located on the side of the turntable 12. The inner side of the slide plate 10 is also vertically movably connected to the upper rotating shaft 2 13. The gear at the end of the rotating shaft 2 13 is meshed with the gear on the rotating shaft 11. The other end of the rotating shaft 2 13 passes through the through slot on the sleeve plate assembly 8 and extends to the inner side of the toothed sleeve rod 7;

[0036] like Figure 6 As shown, the other end of the second rotating shaft 13 is sleeved with a driving tooth 14 between the toothed sleeve rods 7. The driving tooth 14 is meshed with the toothed sleeve rods 7. The toothed sleeve rods 7 are cylindrical structures and can also be telescopically adapted. The ends are fixed on the transmission box 2 6 and driven by the motor in the transmission box 2 6. According to the rotation direction of the two toothed sleeve rods 7, when the two toothed sleeve rods 7 rotate in the same direction, the driving tooth 14 located in the middle starts to move to one side, thereby driving the slide plate 10 on the top telescopic shaft 5 to slide synchronously. When the two toothed sleeve rods 7 rotate in opposite directions, the driving tooth 14 at this time keeps its original position and starts to rotate, thereby driving the turntable 12 on the rotating shaft 11 to rotate.

[0037] By controlling the rotation direction of the two toothed sleeve rods 7, the entire slide 10 is moved left and right on the telescopic shaft 5 and the turntable 12 on the corresponding shaft 11 is rotated, so that the slide 10 is moved to the top of the corresponding steel template for subsequent crimping work. The specific work is as follows: Figure 5 As shown, positioning frames 17 are fixedly connected on both sides of the skateboard 10, and pads 15 are slidably connected to the positioning frames 17. A tilting lever group 16 is symmetrically installed on both sides of the turntable 12. The single-side tilting lever group 16 is divided into an outer lever and an inner lever, which abuts against the outer wall of one side of the turntable 12 through a movable shaft. As the turntable 12 rotates, the entire tilting lever group 16 abutting against the pads 15 is driven to swing;

[0038] The bottom end of the positioning frame 17 is slidably connected with a pressure strip assembly 18, and the top of the pressure strip assembly 18 is rotatably connected to the tilting lever assembly 16 through a connecting rod. When the turntable 12 rotates and pushes the tilting lever assembly 16 to move upward on one side, the other side of the tilting lever assembly 16 presses the pressure strip assembly 18 downward, causing the pressure strip assembly 18 to move downward while contacting the vertical and horizontal ribs set on the top of the steel template, and tightening the intersection of the vertical and horizontal ribs. In order to further improve the tightening effect and correct the position of the vertical and horizontal ribs at the same time, multiple sets of sliding cross buckles can be set at the bottom of the pressure strip assembly 18. After adjusting the spacing, it is convenient to follow the pressure strip assembly 18 to contact the cross position of the vertical and horizontal ribs, and adjust the placement position of the vertical and horizontal ribs while pressing.

[0039] When the pressure strip assembly 18 contacts the longitudinal and transverse ribs on the inner side of the steel template, the robot arm starts to weld obliquely along the side of the pressure strip assembly 18, following the principle of welding short welds first and then long welds, and the welding of the longitudinal and transverse ribs on one side is completed. At this time, the entire slide 10 is driven to move horizontally to complete the subsequent longitudinal and transverse rib compression work. In the early stage of welding the entire steel template, the longitudinal and transverse ribs on the frame are scanned as a whole, and the intersection area of ​​the longitudinal and transverse ribs is used as the control point, and the control point position is marked by the horizontal and vertical coordinates. The control point is acquired as a whole as the lens at the bottom of the slide 10 moves horizontally, and the entire slide 10 is driven to move to the control point through the external controller. On the control point side, the two toothed sleeve rods 7 rotate in opposite directions at the same time, driving the entire rotating shaft 11 to rotate, and the turntable 12 rotates to push the end of the tilting rod group 16 to press down, moving the pressure bar assembly 18 to the top of the vertical and horizontal ribs and implementing the pressing action. With the completion of welding, the two toothed sleeve rods 7 rotate in the same direction, pushing the entire slide 10 to move, and pressing and fixing the intersection of the vertical and horizontal ribs in the next area of ​​the steel template. The slide 10, which is adjusted by the mechanical arm and the position, presses and fixes the vertical and horizontal ribs during the welding process to avoid the problem of excessive gaps between the vertical and horizontal ribs and the base plate during welding, which affects the subsequent overall welding stability.

[0040] At the same time, taking into account the different depths of different steel templates, the moving distance of the pressure strip assembly 18 for the compaction work can also be adjusted. By manually adjusting the position of the pad 15 on the positioning frame 17, the center support position of the entire seesaw is changed, thereby realizing the adjustment of the sliding distance of the pressure strip assembly 18 on the other side of the tilting rod group 16 to adapt to the crimping installation of longitudinal and transverse ribs on steel templates of different thicknesses.

[0041] Example 2: Cooperate with the robot arm to perform efficient welding. The movable frame 201 and the fixed frame 202 on the top of the entire slide 1 can drive the entire sleeve assembly 8 to adjust the height and deflection angle, such as Figure 2 and Figure 3 As shown, the motor located at the top of the movable frame 201 and the fixed frame 202 drives the drive shaft 203 to rotate, so that the limit blocks 204 can move synchronously in their respective grooves to adjust the height of the side sleeve assembly 8 of the entire sleeve disc 4;

[0042] Secondly, the side sleeve of the limit block 204 is movably connected with a sleeve disc 4, and the motor installed in the transmission box 3 is engaged with the inner teeth of the sleeve disc 4 through the gears, driving the entire sleeve disc 4 to rotate, controlling the overall placement angle of the sleeve plate assembly 8, facilitating subsequent robot-assisted welding, and facilitating the storage of the steel template welding assembly lifting platform. The entire sleeve plate assembly 8 can be disassembled, and the clamping plate assembly 9 installed on the sleeve disc 4 is driven by the cylinder. After disengaging the clamping on both sides of the sleeve plate assembly 8, the entire telescopic shaft 5 and the toothed sleeve rod 7 are disassembled, and then the entire sleeve plate assembly 8 is separated from the slide 1, and finally the movable frame 201 is controlled to move toward the side of the fixed frame 202 to complete the disassembly of the entire steel template welding assembly lifting platform.
