Description

Technical Field

[0001] The utility model relates to the field of welding auxiliary structures, in particular to a diagonal welding auxiliary structure for a steel structure frame of a civil air defense door. Background Art

[0002] Civil defense doors belong to civil defense protection equipment. As the name suggests, civil defense doors are the doors at the entrances and exits of people's defense projects. When processing civil defense doors, it is necessary to fix their structural frames through fixing devices and then weld them through welding equipment.

[0003] However, most of the existing welding processing platforms have a single structure. When welding the steel structure frame of the civil air defense door, in order to prevent deviation during the welding process, workers are often required to manually align the horizontal beam and the vertical beam diagonally and then fix them with a fixing device before proceeding to the next step of welding. This will reduce the overall welding efficiency, and repeated diagonal alignment and fixation will result in a higher workload for the workers. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a diagonal welding auxiliary structure for the steel structure frame of a civil air defense door to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a diagonal welding auxiliary structure of a civil defense door steel structure frame, comprising a placing plate, a limiting plate fixedly installed at one end of the placing plate, and a fixed block fixedly installed at one end of the placing plate, a first connecting rod movably installed inside the fixed block, and a movable plate fixedly installed at one end of the first connecting rod, a connecting block fixedly installed at one end of the movable plate, and a control rod fixedly installed at one end of the connecting block, a threaded rod movably installed inside the placing plate, and a pressure block fixedly installed in the middle of the threaded rod, a threaded block matching the thread of the threaded block fixedly installed inside the control rod, a connecting plate fixedly installed at one end of the placing plate, and a second connecting rod movably installed inside the connecting plate, and a limiting frame fixedly installed at one end of the second connecting rod.

[0006] By adopting the above technical solution, by setting components such as a limit frame, a pressure block, a control rod, a threaded rod and a movable plate, when using the equipment, workers can directly position the placed vertical rods through the limit frame, and at the same time push the movable plate to fix and limit the structural frame to be welded together with the limit frame, so as to ensure the stability of the steel structure frame during the welding process. Compared with the traditional workers manually positioning and fixing the frame, this equipment is more convenient and quick, greatly improves its overall welding efficiency, and effectively reduces the work intensity of workers.

[0007] The utility model is further configured such that a first spring is sleeved on the outside of the second connecting rod, and the limiting frame and the connecting plate are connected via the first spring, and a limiting hole is provided at one end of the second connecting rod.

[0008] By adopting the above technical solution, the first spring is set to continuously apply elastic force to the limit frame, so that after the worker releases the restriction on the second connecting rod, the first spring will lift the position of the welded steel structure frame to facilitate the worker to pick it up.

[0009] The utility model is further configured such that a push plate is fixedly installed at one end of the first connecting rod, and a limiting rod matching the size of the limiting hole is fixedly installed inside the push plate.

[0010] By adopting the above technical solution, the setting of the push plate can facilitate workers to control the position of the movable plate. The limit hole and the limit rod cooperate to ensure that the limit rod enters the limit hole to limit and fix the second connecting rod, thereby ensuring that the position of the steel structure frame will not change during the welding process.

[0011] The utility model is further configured that a fixing plate is fixedly installed at one end of the placement plate, and a third connecting rod is movably installed inside the fixing plate, and a limiting block is fixedly installed at one end of the third connecting rod.

[0012] By adopting the above technical solution, the fixed plate provides support for the third connecting rod, and the movably installed third connecting rod allows it to move inside the fixed plate. The third connecting rod is fixedly connected to the limit block, so that the worker can control the movement of the limit block by pulling the third connecting rod, thereby releasing the limit on the movable plate.

[0013] The utility model is further configured that a second spring is sleeved on the outside of the third connecting rod, and the fixed plate and the limit block are connected by the second spring, and one side end surfaces of the movable plate and the limit block are both configured in an arc shape.

[0014] By adopting the above technical solution, the second spring continuously applies elastic force to the limit block, so that after the limit block is squeezed, it will drive the third connecting rod to move backward. After the squeezing force is lost, the second spring will help the limit block to reset, limit and fix the movable plate. The end faces of the movable plate and the limit block are both arc-shaped, which can better control the extrusion direction and prevent the limit block from affecting the movement of the movable plate.

[0015] The utility model is further configured that the connecting block, the control rod, the threaded rod, the threaded block, the pressure block, the limiting frame, the second connecting rod and the first spring are all symmetrically arranged in two groups.

[0016] By adopting the above technical solution, two groups of symmetrically arranged connecting blocks, control rods, threaded rods, threaded blocks, pressure blocks, limit frames, second connecting rods and first springs can better limit the two groups of frame vertical rods to ensure the stability of the steel structure frame during the welding process.

[0017] In summary, the utility model mainly has the following beneficial effects:

[0018] 1. The utility model provides components such as a limit frame, a pressure block, a control rod, a threaded block and a movable plate, so that when workers use the equipment, they can directly position the placed vertical rods through the limit frame, and at the same time push the movable plate to fix and limit the structural frame to be welded together with the limit frame, so as to ensure the stability of the steel structure frame during the welding process. Compared with the traditional workers manually positioning and fixing the frame, the equipment is more convenient and quick, greatly improves its overall welding efficiency, and effectively reduces the work intensity of the workers.

[0019] 2. The utility model is provided with components such as a second connecting rod, a first spring, a second spring, a third connecting rod and a limit block, so that after the movable plate moves to a certain distance, the limit block will fix and limit it to prevent the position of the movable plate from moving backward during the welding process and affecting the stability of the steel structure frame. At the same time, after the welding of the frame is completed, it is only necessary to pull the push plate to make the pressure block release the restriction on the limit frame, and the first spring applies elastic force to the frame to lift the position of the welded steel structure frame, which is convenient for workers to pick it up and improves their overall work efficiency.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] A diagonal welding auxiliary structure for a steel structure frame of a civil air defense door, such as Figure 1-4 As shown, it includes a placement plate 1, a limit plate 2 is fixedly installed at one end of the placement plate 1, and a fixed block 3 is fixedly installed at one end of the placement plate 1, a first connecting rod 4 is movably installed inside the fixed block 3, and a movable plate 5 is fixedly installed at one end of the first connecting rod 4, a connecting block 7 is fixedly installed at one end of the movable plate 5, and a control rod 8 is fixedly installed at one end of the connecting block 7, a threaded rod 10 is movably installed inside the placement plate 1, and a pressing block 11 is fixedly installed in the middle of the threaded rod 10, and a threaded block 9 matching the thread of the threaded rod 10 is fixedly installed inside the control rod 8 A connecting plate 21 is fixedly installed at one end of the placement plate 1, and a second connecting rod 13 is movably installed inside the connecting plate 21. A limiting frame 12 is fixedly installed at one end of the second connecting rod 13. The worker first puts the vertical rod to be welded into the limiting frame 12, and then pushes the movable plate 5 to move. The threaded block 9 at one end of the control rod 8 drives the threaded rod 10 to drive the pressing block 11 to rotate, and controls the position of the limiting frame 12 to move downward. At the same time, after the movable plate 5 moves a certain distance, the limiting rod 16 enters the limiting hole 15 to limit and fix the position of the limiting frame 12.

[0028] See also Figure 2 The second connecting rod 13 is sleeved with a first spring 14 on the outside, and the limit frame 12 is connected to the connecting plate 21 through the first spring 14. A limit hole 15 is opened at one end of the second connecting rod 13. The setting of the first spring 14 enables it to continuously apply elastic force to the limit frame 12, so that after the worker releases the restriction on the second connecting rod 13, the first spring 14 will lift the position of the welded steel structure frame, making it convenient for the worker to pick it up.

[0029] See also Figure 1 - Figure 2 A push plate 6 is fixedly installed at one end of the first connecting rod 4, and a limiting rod 16 matching the size of the limiting hole 15 is fixedly installed inside the push plate 6. The setting of the push plate 6 can facilitate workers to control the position of the movable plate 5. The limiting hole 15 cooperates with the limiting rod 16 to ensure that the limiting rod 16 enters the limiting hole 15 to limit and fix the second connecting rod 13, thereby ensuring that the position of the steel structure frame will not change during the welding process.

[0030] See also Figure 4 A fixed plate 17 is fixedly installed at one end of the placement plate 1, and a third connecting rod 18 is movably installed inside the fixed plate 17. A limit block 20 is fixedly installed at one end of the third connecting rod 18. The fixed plate 17 provides support for the third connecting rod 18. The movably installed third connecting rod 18 allows it to move inside the fixed plate 17. The third connecting rod 18 is fixedly connected to the limit block 20, so that the worker can control the movement of the limit block 20 by pulling the third connecting rod 18, which is used to release the limit on the movable plate 5.

[0031] See also Figure 4 A second spring 19 is sleeved on the outside of the third connecting rod 18, and the fixed plate 17 is connected to the limit block 20 through the second spring 19. The end faces of one side of the movable plate 5 and the limit block 20 are both arc-shaped. The second spring 19 continuously applies elastic force to the limit block 20, so that after the limit block 20 is squeezed, it will drive the third connecting rod 18 to move backward. After the squeezing force is lost, the second spring 19 will help the limit block 20 to reset, limit and fix the movable plate 5. The end faces of the movable plate 5 and the limit block 20 are both arc-shaped, which can better control the extrusion direction and prevent the limit block 20 from affecting the movement of the movable plate 5.

[0032] See also Figure 1 - Figure 2 The connecting block 7, the control rod 8, the threaded block 9, the threaded rod 10, the pressure block 11, the limit frame 12, the second connecting rod 13 and the first spring 14 are all symmetrically arranged in two groups. The two groups of symmetrically arranged connecting blocks 7, the control rod 8, the threaded block 9, the threaded rod 10, the pressure block 11, the limit frame 12, the second connecting rod 13 and the first spring 14 can better limit the two groups of frame vertical rods to ensure the stability of the steel structure frame during the welding process.

[0033] The working principle of the utility model is as follows: the worker first places the cross bar on the end face of the placement plate 1, fixes and limits it to a certain extent through the limit plate 2, and then puts the vertical bar to be welded into the limit frame 12. The worker pushes the movable plate 5 to move, and drives the threaded rod 10 to drive the pressing block 11 to rotate through the threaded block 9 at one end of the control rod 8, so as to control the position of the limit frame 12 to move downward. At the same time, after the movable plate 5 moves a certain distance, the limit rod 16 enters the limit hole 15 to limit and fix the position of the limit frame 12. During the movement of the movable plate 5, the limit block 20 is squeezed to continuously move. The movable plate 5 is moved, and an elastic force is applied to the limit block 20 through the second spring 19. The movable plate 5 is fixed and restricted by the limit block 20 to ensure the stability of the steel structure frame during welding. After welding is completed, the worker pulls the third connecting rod 18 to release the restriction of the limit block 20 on the movable plate 5, and pulls the push plate 6 to make the limit rod 16 disengage from the limit hole 15. At the same time, the threaded rod 10 rotates in the opposite direction to help the limit frame 12 to reset. At the same time, the first spring 14 applies an elastic force to the limit frame 12 to lift the position of the welded steel structure frame to facilitate the workers to take it and complete the welding of the corners of the steel structure frame.
