Description

Technical Field

[0001] The present invention relates to the technical field of steel plank welding, and particularly to a steel plank welding device with an automatic positioning function. Background Art

[0002] Steel planks are plate-shaped components made of steel, used for scaffolding construction, allowing construction workers to stand and walk, and place construction tools and materials. They are mainly applied to construction sites such as building projects, bridge construction, and shipbuilding, and are indispensable safety facilities and working platforms during the construction process;

[0003] In the welding process of steel planks, when welding stiffeners and protective frames onto the steel planks, the operator needs to hold the stiffeners and protective frames by hand and insert the stiffeners into the inner frame of the steel planks for welding. To ensure the shear resistance and bearing capacity of the steel planks, the positions of the stiffeners need to be arranged at equal intervals during welding. During operation, it is not convenient to accurately control the spacing of the stiffeners. Therefore, the positions of the stiffeners on the welded steel planks are likely to deviate, which may affect the bearing capacity of the steel planks. For this reason, we have proposed a steel plank welding device with an automatic positioning function. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In the present invention, through the provided plate positioning mechanism, when the bearing plate slides on the side frame towards the other end of the operating table, when the folding rod passes above the release plate, it is lifted upwards by the release plate, so that the buckle strip disengages from the buckle hole on the sliding frame, and the two clamping pieces approach relatively, realizing the automatic positioning of the steel formwork body, making the steel formwork located in the middle of the bearing plate, and clamping the steel formwork;

[0020] 2. In the present invention, through the provided rib installation mechanism, when the lifting seat moves towards the depression of the track, it drives the outer sleeve and the pneumatic fixture to move downwards. Subsequently, when the lifting seat contacts the bottom surface of the track, the lifting seat keeps the rib horizontal, the guide rod at the top of the inner sleeve contacts the surface of the guide disc, and the outer sleeve, the pneumatic fixture and the rib rotate synchronously, causing the rib to rotate 90 degrees after fitting with the surface of the steel formwork, and the two ends of the rib fit with the two sides of the inner wall of the steel formwork, realizing the automatic positioning and installation of the rib, and the rib is symmetrical with the steel formwork.

[0021] 3. In the present invention, through the provided guard frame installation mechanism, after the steel formwork enters the inside of the receiving frame, it is blocked by the check member. The pushing table pushes the guard frame towards both ends of the steel formwork. During this process, the slope frame presses the roller, and the positioning auxiliary strip swings away from the end connected to the pushing seat to the side of the steel formwork. The guard frame frames the end face of the steel formwork, and the positioning auxiliary strip keeps the guard frame centered during the positioning process to avoid deviation;

[0022] 4.

[0049] In this embodiment, when the carrying plate 501 is returning to its original position, after it approaches the trigger rod 506, the right-angle frame 507 is abutted by the trigger rod 506, and the right-angle frame 507 rotates at the connection between it and the carrying plate 501, and pushes a slide 503 abutted on the other side to slide to the outside of the carrying plate 501, and under the action of the spring pressure above the buckle strip 504, the bottom of the buckle strip 504 buckles into the buckle hole 505, so that the carrying plate 501 automatically opens the clamping piece 502 during the returning process to automatically position the steel springboard;

[0050] In this embodiment, when the slide 503 on one side slides toward the outer side of the carrier plate 501, the upper rack 511 drives the gear 510 to rotate, so that the lower rack 509 pushes the slide 503 on the forest side to slide synchronously, so that the clamping pieces 502 on both sides are opened synchronously;

[0052] Please refer to Figure 5 , Figure 7 , Figure 8 As shown in [relevant figures], the present invention provides a technical solution: The rib installation mechanism 6 includes a support frame 601 fixedly connected to the bearing plate 501. At the top of the support frame 601, top frames 602 are symmetrically arranged. An inner sleeve 603 is rotatably connected to the top of the top frame 602. An outer sleeve 604 is slidably connected to the outside of the inner sleeve 603. A pneumatic clamp 605 is fixedly connected to the bottom of the outer sleeve 604.

A guide rod 607 is fixedly connected to the top end of the inner sleeve 603.

[0053] One end of the guide rod 607 away from its connection with the inner sleeve 603 is fixedly connected to a first tension spring 608, and the first tension spring 608 is connected to the top frame 602. On the top frame 12, a track 609 and a guide disk 610 are respectively arranged. The middle of the track 609 is recessed and its bottom surface abuts against the lifting seat 606. The side surface of the guide disk 610 abuts against the guide rod 607 for causing the guide rod 607 to rotate. The guide disk 610 is set as a flat-angle triangle, and its function is to cause the guide rod 607 to return after rotation.

[0054] In this embodiment, a guide groove is provided on the inner sleeve 603, and the outer sleeve 604 is slidably connected to the inner sleeve 603 through the guide groove. When the guide rod 607 drives the inner sleeve 603 to rotate, it can drive the rib to rotate synchronously through the outer sleeve 604.

[0055] In this embodiment, in the initial state, the rib is parallel to the bearing plate 501. The rib is a reinforcing rib material for improving the load-bearing strength of the steel plank.

A torsion spring 709 is arranged at the connection of the positioning auxiliary bar 707 and the pushing seat;

[0058] In this embodiment, since the edges of the steel gangplank are prone to wear, collision and other external forces during use, by welding guard frames at both ends of the steel gangplank, the thickness and strength of the edges can be increased, the risk of edge deformation and damage can be reduced, the service life of the steel gangplank can be extended, and the size of the guard frame is slightly larger than that of the steel gangplank, which is convenient for installation;

[0059] Please refer to Figures 10 to 11 , the present invention provides a technical solution: the turning plate mechanism 8 includes a guide bar 801 slidably installed on the fixed frame 11. A turning rack 802 is slidably connected to the guide bar 801. Above the turning rack 802, there is a receiving frame 803 rotatably connected to the operating table 1. The receiving frame 803 is arranged in a frame shape with an opening at one end;

[0060] A disc 804 is fixedly connected to the receiving frame 803. A pressing plate 805 is hinged to the disc 804. A second tension spring 806 is connected to the side of the pressing plate 805 close to the disc 804. A toothed ring 807 is sleeved and installed on the disc 804.

[0061] A check member 809 is slidably connected to the receiving frame 803. The bottom of the check member 809 is wedge-shaped. A placing table 810 is fixedly installed at the rear side of the operating table 1. Extension plates 811 are symmetrically arranged on the placing table 810 respectively;

[0063] In this embodiment, please refer to Figure 10 , a cross bar is fixedly installed on the back of the receiving frame 803, and a stop bar is arranged above it, which can keep the receiving frame 803 in a horizontal state after returning to its position and will not continue to rotate and swing downward;

[0064] The usage method and advantages of the present invention: The steel gangplank welding equipment with an automatic positioning function works as follows:

[0065] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 shown below:

[0066] S1: In the initial state, the plate positioning mechanism 5 is located on one side of the operating table 1 close to the driving motor 2, and the clamping pieces 502 on both sides of the bearing plate 501 are far away from each other. The operator places the opening of the steel gangplank to be welded upward on the bearing plate 501, places the rib and the guard frame in front of the pneumatic fixture 605 and the pushing table 703 respectively, and then starts the driving motor 2 to work. By rotating the reciprocating lead screw 4, the bearing plate 501 is driven to slide on the side frame 3 towards the other end of the operating table 1. During this process, the folding rod 508 passes above the release plate 512 and contacts the release plate 512, and is pushed upward by the release plate 512. The buckle strip 504 moves upward synchronously, so that the buckle strip 504 disengages from the buckle hole 505 on the sliding frame 503. The spring at the connection between the clamping piece 502 and the bearing plate 501 is quickly released, so that the two clamping pieces 502 approach each other relatively. When contacting the side of the steel gangplank, the positioning of the steel gangplank body is realized, so that the steel gangplank is located in the middle of the bearing plate 501, and the steel gangplank is clamped. As the bearing plate 501 continues to move, the lifting seat 606 contacts the depression of the track 609, so that the lifting seat 606 drives the outer sleeve 604 and the pneumatic fixture 605 to move downward. The rib on the pneumatic fixture 605 approaches the steel gangplank. When the lifting seat 606 is close to the bottom end of the track 609, the bottom surface of the steel gangplank is close to the surface of the steel gangplank. Subsequently, the lifting seat 606 contacts the bottom surface of the track 609. Since the bottom surface is a plane, the lifting seat 606 keeps the rib horizontal. At this time, the guide rod 607 at the top of the inner sleeve 603 contacts the surface of the guide disk 610. As the bearing plate 501 continues to move, friction is generated between the guide rod 607 and the guide disk 610, and rotation gradually occurs, pulling the first tension spring 608 outward. Through the notch opened on the inner sleeve 603, the outer sleeve 604, the pneumatic fixture 605 and the rib rotate synchronously, so that the rib rotates 90 degrees after fitting with the surface of the steel gangplank. The two ends of the rib fit with both sides of the inner wall of the steel gangplank, realizing the automatic positioning and installation of the rib. The relative positions of the two ribs and the steel gangplank are symmetrical. After the bearing plate 501 continues to move, the guide seat moves upward gradually away from the bottom surface of the track 609, so that the pneumatic fixture 605 is moved away from the steel gangplank;

[0067] S2: After the rib positioning is completed, the steel plank enters the interior of the receiving rack 803. During this process, the bearing plate 501 pushes the flipping rack 802 to pass under the receiving rack 803. The flipping rack 802 drives the gear ring 807 to rotate. The side frame of the steel plank contacts the surface of the check member 809 and jacks up the check member 809. Subsequently, the check member 809 automatically drops and catches the side frame of the steel plank. Then, under the action of the reciprocating lead screw 4, the bearing plate 501 returns to its original position, and the steel plank is left on the receiving rack 803. The extension plates 811 on both sides support the steel plank. The two clamping pieces 502 automatically disengage from both sides of the steel plank during the return of the bearing plate 501. Then, the first electric push rod 702 is activated to drive the pushing platform 703 to extend outwards and approach the side of the steel plank. During this process, the slope frame 706 squeezes the roller 708, causing the roller 708 to rotate with the positioning auxiliary bar 707 as the axis at its connection with the pushing seat 701. The end of the positioning auxiliary bar 707 away from the connection with the pushing seat swings to the side of the steel plank. The guard frame on the pushing platform 703 is synchronously pushed by the pushing platform 703 and frames the side of the steel plank. The positioning auxiliary bar 707 keeps the guard frame centered during the positioning process to avoid deviation. Then, the second electric push rod 901 is activated to control the first welding head 902 and the second welding head 903 to move downwards to perform welding operations on the installation ribs and guard frame of the steel plank. After the welding is completed, the electric push rod controls the first welding head 902 and the second welding head 903 to quickly lift upwards. The first electric push rod 702 controls the pushing platform 703 to return to its original position. The positioning auxiliary bar 707 automatically returns to its original position under the action of the torsion spring 709;

[0068] S3: After the rib welding is completed, when the bearing plate 501 drives the guide bar 801 to pass under the receiving rack 803, the flipping rack 802 contacts the end of the guide bar 801, keeping the flipping rack 802 and the guide bar 801 in a relatively stationary state so that the guide bar 801 can drive the flipping rack 802 to move, thereby driving the gear ring 807 to rotate. During this process, the gear ring 807 flips and catches the abutment plate 805 through the internal tooth openings 808 opened on its inner surface. During the rotation, the disk 804 is driven to rotate through the abutment plate 805, so that the receiving rack 803 drives the steel plank to rotate 180 degrees with its connection with the operating table 1 as the axis, turning over the preliminarily welded steel plank. The steel plank falls on the placing table 810. The bearing plate 501 continues to move forward, causing the flipping rack 802 to disengage from the gear ring 807. The third electric push rod 904 is activated to drive the third welding head 905 to approach the steel plank, above both sides of the steel plank where the guard frame is installed. The third welding head 905 performs welding here to complete the welding operation of the steel plank.
