Description

Technical Field

[0001] The invention relates to the field of welding, and in particular to a welding device for prefabricated concrete components. Background Art

[0002] Embedded parts (prefabricated embedded parts) are prefabricated components for concrete. They are components pre-installed in concealed projects and are also components placed during structure pouring. They are used for overlap when building superstructures to facilitate the installation and fixation of the foundation of external engineering equipment.

[0003] Fig. 9 The invention includes a certain type of prefabricated component, which is respectively composed of four bent steel bars and steel plates welded together. The traditional processing method is to bend four steel bars separately, and then position the four steel bars along the ring separately, and weld the steel bars to the steel plate one by one. For example, an automatic positioning welding platform for embedded parts with announcement number CN114799704B relates to the technical field of welding platforms, including a support tray, the support tray is a rectangular structure, and a row of longitudinally supported square railings are welded at equal intervals inside the support tray. The prior art can save the trouble of manually opening and closing the steel bar holding assembly when loading and unloading the embedded parts before and after the processing operation, and solves the cumbersome and inefficient welding operation of the embedded parts.

[0004] Another example is a construction embedded parts auxiliary welding device with announcement number CN117139977A, which includes a base plate, a rotation positioning trigger mechanism, a centering fixing mechanism and a steel bar clamping mechanism. This prior art solves the problem that the positioning and fixing of thin steel bars are difficult to ensure in the production quality during the single-person welding of four-claw embedded parts, by setting a mechanism that allows the rotating steel plate to enter a stable rotation position above the welding point and allows the thin steel bar fixing clamp to rotate to a corresponding angle.

The disadvantages of this are that, on the one hand, the operation is more complicated, and on the other hand, the processing efficiency is low. Therefore, the present application designs a prefabricated component welding device, which improves the processing efficiency of prefabricated components by simultaneously bending and positioning steel bars and steel plates.

[0041] The bending assembly 9 includes a rotating table 91, in which a bending rod 1 92 is connected through a bearing, and the other end of the bending rod 1 92 is connected to a rotating plate 93, and the rotating plate 93 is fixedly connected to a bending rod 2 94.

A plurality of rotating grooves 95 cooperating with the rotating plate 93 are provided in the annular table 5. The rotating plate 93 rotates in the rotating grooves 95 and is limited by the rotating grooves 95. The bottom of the rotating plate 93 is provided with Groove 96, after the rotating plate 93 is rotated to a vertical state, the groove 96 is matched and connected with the outer part of the limit platform 4, so that the rotation process of the rotating plate 93 can be satisfied. Each rotating plate 93 is connected with a pressure component, and the pressure component includes a hydraulic cylinder 97 and a connecting ball 98. The fixed end of the hydraulic cylinder 97 is rotatably connected to the support plate 2 through the connecting platform 910. A movable groove 99 with a "T"-shaped structure is opened on the top of the rotating plate 93. The connecting ball 98 is inserted into the movable groove 99 through a connecting rod connected to the hydraulic cylinder 97. In this way, the rotation of the rotating plate 93 can be realized by the extension of the hydraulic cylinder 97.

[0042] The positioning assembly 7 includes a lifting platform 71 connected to the bottom plate 1. The lifting platform 71 can make the welding platform 6 rise or move down. The welding platform 6 is fixed on the top of the lifting platform 71. The welding platform 6 is set to a square structure and four clamping plates 72 are connected to the outside. The four clamping plates 72 are respectively connected to the four sides of the welding platform 6. Each clamping plate 72 is connected to a compression rod 73, wherein the clamping plates 72 and the compression rod 73 are connected by magnets, so that the two can be connected to each other for positioning work and can be separated from each other. A plurality of slide grooves 74 are vertically opened on each side of the welding platform 6, and each slide groove 74 is sealed and slidably connected with a slider 75. A plurality of sliders 75 located on the same side are fixed together at the bottom of the corresponding clamping plate 72, and a connecting box 76 is connected to the other side of each compression rod 73, and each connecting box 76 is fixed to the support plate 2 on the corresponding side through a bracket 712, wherein the position of the connecting box 76 on the support plate 2 is adjustable, and can be adaptively installed according to different types of embedded parts, so that the compression rod 73 is always located at the processing height of the welding table 6, and a piston 77 is sealingly and slidably connected in the connecting box 76, and one side of the piston 77 is fixedly connected to the compression rod 73, and a spring 78 is sleeved on the compression rod 73, and the two ends of the spring 78 are respectively connected to the inner wall of the connecting box 76 and the piston 77.

The winding wheel 1 710 and the winding wheel 2 711 are both connected to the support plate 2 on the corresponding side through a connecting shaft. The winding wheel 1 710 and the rotating platform 91 are located in the same plane and the winding wheel 2 711 is located directly below the winding wheel 2 711. The elastic rope 79 is respectively wound around the winding wheel 1 710 and the winding wheel 2 711 in the clockwise and counterclockwise directions. The other end of the elastic rope 79 passes through the connecting box 76 and is fixedly connected to the piston 77, so that the elastic rope 79 can drive the piston 77 to move, thereby causing the compression rod 73 to move toward the direction of the clamping plate 72. The bottom of the lifting platform 71 is rotatably connected to the base plate 1 through the turntable 10. The support platform 3 is coaxially connected to the central axis. The top of the central axis is connected to the driving motor 8 and the fixed end of the driving motor 8 is installed on the support platform 3 through bolts. The bottom of the central axis is connected to the limit platform 4, and a torsion spring is connected between the turntable 10 and the base plate 1.

[0044] When the present invention is used, the steel plate 43 is first placed on the welding table 6, and then four steel bars 42 are placed in the limiting grooves 41 and abut against the steel plate 43 located below, and the lifting platform 71 is raised to the height at which the steel bars 42 are bent, and then a plurality of hydraulic cylinders 97 are started, and the hydraulic cylinders 97 will push the plurality of rotating plates 93 to rotate, so that the bending rod 1 92 and the bending rod 2 94 connected to each rotating plate 93 together bend the steel bars 42 in the corresponding limiting grooves 41;

[0045] In the above process, the rotation of the rotating plate 93 will simultaneously pull the elastic rope 79, which will be transmitted through the winding wheel 1 710 and the winding wheel 2 711, thereby driving the piston 77 located in the connecting box 76 to move, and the movement of the piston 77 will drive the compression rod 73 connected to the piston 77 to move toward the direction of the clamping plate 72. From the overall perspective, multiple compression rods 73 will enable multiple clamping plates 72 to jointly position the steel plate 43, so that the steel plate 43 and the four steel bars 42 will be simultaneously positioned to the position state of the processed product, so that welding work can be conveniently performed through the welding table 6.

[0046] Then after welding is completed, the four steel bars 42 and the steel plate 43 are welded into a whole, and then the driving motor 8 is started, so that the limit table 4 drives the product to rotate 45° and makes the limit groove 41 coincide with the connecting groove 51, so that on the one hand, the positioning of the bending component 9 on the multiple steel bars 42 can be released, and on the other hand, the bent steel bars 42 have space to move downward, and then the lifting platform 71 is moved downward, so that the welded product is separated from the limit table 4, and the hydraulic cylinder 97 retracts, so that the rotating plate 93 rotates and pulls the elastic rope 79, so that the pressure of the multiple compression rods 73 on the clamping plate 72 can be released under the action of the spring 78, so that the welded product can be taken out, and then under the action of the torsion spring, the turntable 10, the lifting platform 71 and the welding table 6 rotate to the initial state, which is convenient for the subsequent processing of prefabricated components.
