Description

Technical Field

[0001] This utility model relates to the field of welding devices, and in particular to a retractable wet joint welding device. Background Technology

[0002] A wet joint refers to a prestressed concrete beam that is prefabricated in sections and cantilevered to form a large-span continuous beam. The beam sections are connected by cast-in-place concrete. Before construction of a wet joint, the internal reinforcing steel bars need to be welded. During welding, high-temperature welding slag and molten slag will splatter and fall, which may cause a fire. To eliminate fire hazards, a fire catcher is usually used to catch the welding slag. However, due to the significant difference between the working environment and wet joints, the fire catcher is often incompatible with wet joints and cannot be used in practice, resulting in poor versatility of the fire catcher. Utility Model Content

[0003] The purpose of this invention is to solve the problem that the fire-receiving bucket has poor versatility and is easily incompatible with wet joints, making it unusable.

[0004] The technical solution of this utility model is as follows: A retractable wet joint welding and fire-fighting device, comprising a main frame, with support frames slidably connected to both sides of the main frame, universal wheels rotatably connected to the bottom of the support frames, a housing fixedly connected to one side of the main frame, a connecting square tube slidably connected to the inner side of the housing, a sliding sleeve frame fixedly connected to the bottom of the connecting square tube, a receiving bucket assembly provided at the bottom of the sliding sleeve frame, the receiving bucket assembly including a shaft sleeved on the inner side of the sliding sleeve frame, a central base fixedly connected to the bottom of the shaft, and fire-fighting buckets hinged to both sides of the central base.

[0005] Optionally, an inner sleeve bucket is slidably connected to the inner side of each of the two fire-receiving buckets, and a limit block is fixedly connected to the inner wall of the fire-receiving bucket.

[0006] Optionally, a round rod is fixedly connected to the inner wall of the fire-receiving hopper, and a transmission rod is slidably sleeved on the outer side of the round rod.

[0007] Optionally, one end of the transmission rod is hinged to a slider, which is slidably connected inside the connecting square tube.

[0008] Optionally, a pull rope is fixedly connected to the top of the slider, and a pull ring is fixedly connected to the top of the pull rope.

[0009] Optionally, the internal thread of the sliding sleeve bracket is connected with a fastening bolt, which is arranged in an abutting position against the shaft.

[0010] Optionally, a positioning block is fixedly connected to the outside of the pull rope, and a slot is provided on the top of the connecting square tube to match the contour of the positioning block.

[0011] Optionally, a spring sheet is fixedly connected inside the connecting square tube, and a solid ball is fixedly connected to the outside of the spring sheet.

[0012] Optionally, a plurality of positioning holes adapted to the diameter of the solid marble are provided on one side of the casing, and the solid marble is inserted into the positioning holes provided on one side of the casing.

[0013] Optionally, the inner sleeve is fitted onto the outside of the limiting block.

[0014] In summary, this application includes at least one of the following beneficial technical effects: This invention can adjust the shape of the device according to the width and height of the wet joint to adapt to different wet joints and working environments, thereby avoiding the situation where it cannot be used due to incompatibility with the wet joint. At the same time, the multiple size adjustments can not only adapt to various wet joints, but also comprehensively collect welding slag, avoiding the situation where welding slag is misaligned with the wet joint, causing the welding slag to deviate and fail to enter the welding hopper.

[0015] Furthermore, the transmission rod and slider allow the two fire-receiving hoppers on both sides to be flipped and retracted, thereby accumulating the collected welding slag for subsequent cleaning. At the same time, the retraction of the two fire-receiving hoppers reduces the size of the device, making it easier to collect, store, and transfer the device after welding, thus improving the convenience of using the device.

[0016] In summary, this utility model adapts to different wet joints and working environments by adjusting the size. At the same time, the folding design of the two fire-receiving hoppers on both sides not only allows for the accumulation of welding slag, but also facilitates the collection, storage, and transfer of the device. Furthermore, the device is simple to operate, can be completed by a single person, can be recycled, has low production costs, and is easy to popularize and use. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1: As Figures 1-4As shown, a retractable wet joint welding ignition device includes a main frame 1, with support frames 2 slidably connected to both sides of the main frame 1. Universal wheels 3 are rotatably connected to the bottom of the support frames 2. A housing 4 is fixedly connected to one side of the main frame 1, and a connecting square tube 5 is slidably connected to the inner side of the housing 4. A sliding sleeve frame 6 is fixedly connected to the bottom of the connecting square tube 5. A receiving bucket assembly is provided at the bottom of the sliding sleeve frame 6. The receiving bucket assembly includes a shaft 7 sleeved inside the sliding sleeve frame 6. A central base 8 is fixedly connected to the bottom of the shaft 7. Receiving buckets 9 are hinged to both sides of the central base 8. The inner side of the fire bucket 9 is slidably connected to the inner sleeve bucket 10. The inner wall of the fire bucket 9 is fixedly connected to the limit block 11. The inner sleeve bucket 10 is sleeved on the outer side of the limit block 11. The inside of the connecting square tube 5 is fixedly connected to the spring plate 19. The outside of the spring plate 19 is fixedly connected to the solid ball 18. The side of the shell 4 is provided with multiple positioning holes that are adapted to the diameter of the solid ball 18. The solid ball 18 is inserted into the positioning holes on the side of the shell 4. The inside of the support frame 2 is also provided with solid ball 18 and spring plate 19. The top of the main frame 1 is also provided with positioning holes.

[0025] In this embodiment, since the wet joint is located in the gap between the two beams, when collecting welding slag, the central base 8 and the slag-collecting hopper 9 are placed directly below the wet joint, with the casing 4 and the connecting square tube 5 positioned between the wet joint. The support frames 2 on both sides are located on top of the beams on both sides. The entire device is moved by the rotation of the casters 3, allowing the slag-collecting hopper 9 to move with the welding progress, thus achieving the purpose of following the welding process. At the same time, the main frame 1 can also house the welding equipment, allowing it to move with the welding progress and facilitating the welder's movement of the equipment. Furthermore, the sliding connection between the support frames 2 on both sides and the main frame 1 allows for easy access to the welding equipment by the welder. The solid ball 18, spring plate 19, and positioning hole at the top of the main frame 1 allow the support frame 2 to lose its positioning by disengaging the solid ball 18 from the positioning hole of the main frame 1. This allows the support frame 2 to slide out from the inside of the main frame 1, increasing the overall length of the main frame 1 and the two side support frames 2. The solid ball 18 is then reinserted into the positioning hole at the top of the main frame 1 to fix the support frame 2 in place. This allows the top area of ​​the main frame 1 and the support frame 2 to be adjusted according to the volume of the welding equipment to accommodate welding equipment of different sizes. When the width is relatively large, the overall length of the main frame 1 and the support frame 2 can be adjusted in the same way to accommodate the width of the wet joint.

[0026] The overall length of the sleeve 4 and the connecting square tube 5 can also be adjusted. By pressing the solid ball 18 inside the connecting square tube 5, it can be disengaged from the positioning hole on one side of the central base 8, allowing the connecting square tube 5 to rise and fall inside the sleeve 4. After the adjustment of the connecting square tube 5 is completed, the elastic deformation force of the spring plate 19 can cause the solid ball 18 to be inserted into the corresponding positioning hole of the central base 8 to fix the connecting square tube 5. In this way, the overall length of the connecting square tube 5 and the central base 8 can be adjusted according to the thickness of the beam plate, so that the central base 8 and the fire-catching hopper 9 are at a suitable height to catch the welding slag, and at the same time, the height of the central base 8 and the fire-catching hopper 9 is not too low, resulting in a large distance from the wet joint, so that when the welding slag falls, it is affected by the wind and does not enter the central base 8 and the fire-catching hopper 9.

[0027] Under the limiting and guiding action of the limiting block 11, the inner sleeve 10 can slide inside the fire-receiving hopper 9, and gradually detach from the inside of the fire-receiving hopper 9. This can extend the inner area of ​​the fire-receiving hopper 9 and the inner sleeve 10, so as to adapt to wet joints of different widths and avoid the situation where the length of the fire-receiving hopper is insufficient due to the wet joint being too wide, resulting in the inability to collect all the welding slag.

[0028] Example 2: Figures 1-4 As shown, a round rod 12 is fixedly connected to the inner wall of the fire-receiving hopper 9. A transmission rod 13 is slidably sleeved on the outer side of the round rod 12. The transmission rod 13 can slide on the outer side of the round rod 12. A slider 14 is hinged to one end of the transmission rod 13. The slider 14 is slidably connected inside the connecting square tube 5. A pull rope 15 is fixedly connected to the top of the slider 14. The pull rope 15 is a relatively soft rope. A pull ring 20 is fixedly connected to the top of the pull rope 15. A fastening bolt 16 is threaded inside the sliding sleeve 6. The fastening bolt 16 is set in an abutting position with the shaft 7. A positioning block 17 is fixedly connected to the outer side of the pull rope 15. A slot hole that matches the contour of the positioning block 17 is opened on the top of the connecting square tube 5.

[0029] In this embodiment, when the device is retrieved after welding, the pull ring 20 is pulled upwards, and the pull rope 15 pulls the slider 14, causing the slider 14 to move upwards inside the connecting square tube 5. This, in turn, pulls the round rod 12 via the transmission rods 13 on both sides, causing the two fire-receiving hoppers 9 to gradually flip upwards and close. During this process, the inner sleeves 10 on both sides gradually slide back to their original position inside the fire-receiving hopper 9 under their own weight. Simultaneously, the welding slag collected inside the fire-receiving hopper 9 and the inner sleeves 10 falls to the inner side of the central base 8 and accumulates, facilitating subsequent cleaning. After the two fire-receiving hoppers 9 flip and close, the positioning block 17 slides out from the slot at the top of the connecting square tube 5. At this point, the pull ring 20 is rotated to twist the pull rope 15, or the positioning block 17 is manually rotated to position the fire-receiving hopper. The slots on the top of the block 17 and the connecting square tube 5 are offset from each other. When the pull ring 20 is released, the positioning block 17 contacts the top of the connecting square tube 5, thereby limiting the pull rope 15 and preventing it from falling. This fixes the fire-receiving hoppers 9 on both sides. Since the fire-receiving hoppers 9 on both sides are vertically closed, the overall volume of the device is reduced. When the device is retrieved, it is easy to separate the central base 8 and the fire-receiving hopper 9 from the bottom of the wet joint. At the same time, when the distance between the fire-receiving hopper 9 and the wet joint is too large to allow the fire-receiving hopper 9 to flip, the connecting square tube 5 can be lowered to extend the distance between the fire-receiving hopper 9 and the wet joint. At the same time, closing the fire-receiving hoppers 9 on both sides reduces the floor space, making it easier to store and transfer the device and improving the convenience of actual use.

[0030] When the fastening bolt 16 is loosened, the sliding sleeve 6 can move to the outside of the shaft 7. At the same time as the sliding sleeve 6 moves, the transmission rod 13 slides to the outside of the round rod 12. Through the displacement of the sliding sleeve 6, the main frame 1 can gradually move to the middle position of the central base 8, so that the main frame 1 and the central base 8 are on the same center line. This can further reduce the footprint of the device and meet the needs of convenient storage and organization of the device in actual use.

[0031] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
