Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] Please refer toFigures 1-5 The utility model provides technical schemes:

[0028] A kind of welding reinforcing device of large structural steel ladle car frame, including workbench 1, the top of workbench 1 is fixedly connected with side plate 2, the top of side plate 2 is provided with gantry 3, the inside of gantry 3 is fixedly connected with crossbar 4, the surface of crossbar 4 is movably connected with positioning assembly 5, positioning assembly 5 includes locating block 501, the surface of locating block 501 is fixedly connected with deodorization component 6;

[0029] Deodorization component 6 includes annular block 601, annular block 601 is fixedly sleeved on the surface of locating block 501, the inside of annular block 601 is provided with cavity and the surface of annular block 601 is provided with multiple suction holes 602, the rear side of annular block 601 is fixedly communicated with corrugated hose 603, the other end of corrugated hose 603 is fixedly communicated with smoke purifier 604, and smoke purifier 604 is fixedly connected to the rear side of workbench 1.

[0030] In the embodiment: by setting deodorization component 6, in welding operation, locating block 501 can be adjusted position according to actual demand, so that annular block 601 is as close to welding point as possible, smoke purifier 604 is started and will have strong negative pressure suction force, under the action of negative pressure, the air containing harmful gas generated by welding is quickly sucked into the cavity in the inside of annular block 601, and the harmful gas sucked into the cavity in annular block 601 is transported to smoke purifier 604 by corrugated hose 603, and smoke purifier 604 is usually provided with filtering device inside, and harmful particles and dust in gas are intercepted by filter screen, and toxic and harmful gas molecules are adsorbed by activated carbon and other adsorbing materials, so that the harmful gas is purified and treated, and the harm of harmful gas to working environment and operating personnel in welding process is reduced.

[0031] Specifically, as shown in Figure 3 The surface of crossbar 4 is slidably connected with adjusting block 502, the bottom of adjusting block 502 is fixedly connected with connecting rod 503, the bottom of connecting rod 503 is fixedly connected with support block 504, support block 504 is screw-connected with moving screw 505 in the inside, and the bottom of moving screw 505 is rotatably connected with the top of locating block 501.

[0032] Specifically, as shown in Figure 3 The bottom of support block 504 is fixedly connected with telescopic rod 506, and the bottom of telescopic rod 506 is fixedly connected with the top of locating block 501.

[0033] Specifically, as shown in Figure 4 The inside of adjusting block 502 is penetrated by plug rod 7, the inside of crossbar 4 is provided with insertion hole 8 matched with plug rod 7, the surface of plug rod 7 is sleeved with fastening tension spring 9, and the two ends of fastening tension spring 9 are fixedly connected with plug rod 7 and adjusting block 502 respectively.

[0034] In this embodiment: With the above settings, the operator can manually push the adjusting block 502 to move on the crossbar 4 according to the actual size of the frame and welding requirements. When the adjusting block 502 moves to the appropriate position, under the action of the fastening spring 9, the insert rod 7 can be quickly inserted into the insert hole 8 to lock the position of the adjusting block 502 and prevent it from shifting in subsequent operations. Then, rotate the moving screw 505. Since the moving screw 505 and the support block 504 are threadedly connected, as the moving screw 505 rotates, it will move downward in the support block 504, thereby driving the positioning block 501 to descend, so that the positioning block 501 will fit tightly against the top of the reinforcement, thereby firmly fixing the reinforcement at the welding point and ensuring that the reinforcement is positioned in the optimal position required for welding, thus improving the welding reinforcement effect.

[0035] Specifically, such as Figure 1 As shown, grooves 10 are provided on both sides of the top of the side plate 2. A lead screw 11 is rotatably connected inside the left groove 10, and a slide rod 12 is fixedly connected inside the right groove 10.

[0036] Specifically, such as Figure 1 As shown, a movable block 13 is threadedly connected to the surface of the lead screw 11, and a slider 14 is slidably connected to the surface of the slide rod 12. Both the movable block 13 and the slider 14 are fixedly connected to the bottom of the gantry frame 3.

[0037] In this embodiment: With the above settings, rotating the lead screw 11 can drive the moving block 13 to move along the axial direction of the lead screw 11. When the moving block 13 moves, it will drive the gantry 3 to move together. Through the cooperation of the slide bar 12 and the slider 14, the gantry 3 can play a guiding and stabilizing role during its movement, ensuring that the gantry 3 will not shake or deviate, and ensuring stability during movement. Thus, the positions of the gantry 3, the deodorizing component 6 and the positioning component 5 can be flexibly adjusted according to the actual welding requirements of the reinforcement components, further improving the flexibility of use.

[0038] Specifically, such as Figure 5 As shown, telescopic cylinders 15 are fixedly connected to both sides of the inner wall of the side plate 2. The telescopic end of the telescopic cylinder 15 is fixedly connected to a clamping plate 16. The side of the clamping plate 16 that is close to each other is made of rubber.

[0039] Specifically, such as Figure 4 As shown, the top and bottom of the crossbar 4 are provided with limit grooves 17, and the top and bottom of the inner wall of the adjusting block 502 are provided with limit strips 18 that cooperate with the limit grooves 17.

[0040] In this embodiment: Through the above settings, the telescopic cylinder 15 can control the position of the clamping plate 16 to achieve the clamping and releasing action of the large structural steel ladle car frame. The clamping force and position can be adjusted according to the size and shape of the frame to adapt to the welding and reinforcement needs of different specifications of frames, ensuring that the frame will not be displaced due to external forces or other factors during the welding process, and providing stable working conditions for the welding work. Through the cooperation of the limiting groove 17 and the limiting bar 18, a limited path can be provided for the movement of the adjusting block 502, so that the adjusting block 502 can only slide on the crossbar 4 along the direction of the limiting groove 17, ensuring the straightness and accuracy of the movement of the adjusting block 502, preventing it from shaking or deviating during the movement, and ensuring that the positioning component 5 and the deodorizing component 6 can accurately reach the predetermined position.

[0041] Working Principle: When welding and reinforcing the steel ladle car frame, first, the large structural component to be welded and reinforced, the steel ladle car frame, is placed on top of the workbench 1. Then, the telescopic cylinder 15 is activated, causing its telescopic end to push the clamping plate 16 to move. The clamping plate 16 gradually approaches the frame, and then the frame is firmly clamped to the top of the workbench 1. Next, the lead screw 11 is rotated. When the lead screw 11 rotates, it drives the moving block 13 to move on the surface of the lead screw 11, thereby moving the gantry 3 together. After the gantry 3 is moved to the appropriate position, the adjusting block 502 is slid along the crossbar 4. According to the welding requirements of the reinforcement component, the adjusting block 502 is moved to the appropriate position, and then the insert rod 7 is inserted into the corresponding insertion hole 8 on the crossbar 4. The elastic force of the fastening spring 9 is used to firmly fix the insert rod 7 in the insertion hole 8, thereby adjusting the position. Block 502 is fixed to the surface of crossbar 4. Then, the moving screw 505 is rotated. The rotation of the moving screw 505 will cause the positioning block 501 to move downward along the telescopic rod 506, so that the positioning block 501 can apply downward pressure to the reinforcement, thereby firmly fixing the reinforcement to the welding point. Then, welding can be carried out. During welding, the fume purifier 604 is activated. The fume purifier 604 generates suction through the corrugated hose 603, which creates a negative pressure inside the annular block 601. At this time, the multiple suction holes 602 on the surface of the annular block 601 will suck the fumes, odors and other harmful gases generated during the welding process into the cavity of the annular block 601. Then, these gases are transported to the fume purifier 604 for treatment through the corrugated hose 603, thereby maintaining the cleanliness of the working environment and the health of the operators.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
