DETAILED DESCRIPTION

[0028] See also Figure 1-2In an embodiment of the present invention, an explosion welding protection device includes a shell 1, an inner cavity of the shell 1 is slidably connected with a symmetrical protection plate 2, the protection plate 2 is elastically connected to the inner cavity side wall of the shell 1, and a symmetrical mounting block 5 is fixedly connected to the lower end of the shell 1, and an end of the mounting block 5 close to the protection plate 2 is fixedly connected to a mounting shell 21, and an end of the mounting shell 21 away from the mounting block 5 is slidably connected to a mounting rod 8, and an end of the mounting rod 8 away from the mounting shell 21 is provided with a baffle 3, and the inner cavity of the mounting shell 21 is provided with an adjustment mechanism for adjusting the angle of the baffle 3. During the explosion welding process, after the impact generated by the explosion pushes the baffle 3 and the mounting rod 8 close to the position of the mounting shell 21, the lower end of the adjustment mechanism pushes the baffle 3 to rotate downward. During the explosion welding process, the plate to be welded is first placed on the ground, and then the shell 1 is placed on the plate to be welded by a crane or other equipment, so that the plate is located in the inner cavity of the shell 1, and then the shell 1 is fixed to the ground by pins, thereby reducing the impact force generated during the explosion.

[0029] See also Figure 3 and Figure 5 The two sides of the mounting rod 8 are horizontally slidably connected to the inner cavity side walls of the mounting shell 21. The end of the mounting rod 8 away from the baffle 3 is elastically connected to the inner cavity side walls of the mounting shell 21 through a spring. The lower end of the mounting rod 8 is fixedly connected to a plurality of blocks 15. The inner cavity bottom of the mounting shell 21 is fixedly connected to a sleeve shell 24 on the side close to the baffle 3. The upper middle part of the sleeve shell 24 is rotatably connected to a clamping plate 25. The end of the clamping plate 25 away from the baffle 3 is elastically connected to the inner cavity bottom of the clamping plate 25 through a spring. The plane where the top end of the clamping plate 25 is located is higher than the plane where the lower end surface of the clamping block 15 is located. When the baffle 3 is subjected to the impact of explosive welding, the clamping plate 25 is located on a plane higher than the plane where the lower end surface of the clamping block 15 is located. When the explosion occurs, the baffle plate 3 drives the mounting rod 8 to move synchronously toward the inner cavity of the mounting shell 21 under the impact force of the explosion. In the process of the mounting rod 8 driving the card block 15 to move synchronously, the card block 15 contacts the side of the card plate 25 close to the baffle plate 3, thereby pushing the card plate 25 to rotate in the direction away from the baffle plate 3, and after the end of the card block 15 away from the baffle plate 3 is separated from the card plate 25, the card plate 25 will be clamped between two adjacent card blocks 15, thereby limiting the position of the mounting rod 8 and the baffle plate 3, that is, through the cooperation of the card plate 25 and the card block 15, the mounting rod 8 can only move toward the inner cavity of the mounting shell 21.

[0030] See also Figure 4 and Figure 7The adjustment mechanism includes a shell 22, which is fixedly connected to the upper part of the inner cavity of the mounting shell 21. A rack 23 is horizontally slidably connected to the middle part of the lower end of the shell 22. The end of the rack 23 away from the mounting rod 8 is elastically connected to the inner cavity side wall of the shell 22 through a spring. A groove 9 is opened at the upper part of the inner cavity of the mounting rod 8. The plane where the bottom of the inner cavity of the groove 9 is located coincides with the plane where the lower end surface of the rack 23 is located. A driving gear 11 is rotatably connected to the middle part of the inner cavity of the mounting rod 8. A driving gear 10 is fixedly connected to one side of the driving gear 11. A rotating rod 12 is rotatably connected to the end of the mounting rod 8 away from the mounting shell 21. The end of the rotating rod 12 away from the mounting rod 8 is connected to the inner cavity of the baffle 3. The side walls are fixedly connected, and a driven gear 13 is fixedly connected to the outer wall of the rotating rod 12 on one side close to the driving gear 11. The driven gear 13 and the driving gear 10 are located in the same vertical plane, and the driven gear 13 and the driving gear 10 have the same size. The outer walls of the driven gear 13 and the driving gear 10 are jointly hinged with a chain 14, that is, when the driving gear 11 rotates, it will drive the driving gear 10 to rotate synchronously, and the driving gear 10 will drive the driven gear 13 to rotate synchronously through the chain 14 during the rotation process, so that when the driving gear 11 rotates, it will synchronously drive the baffle 3 to rotate through the driving gear 10, the chain 14 and the driven gear 13.

[0031] See also Figure 6When the baffle plate 3 is impacted by an explosion, in order to prevent the baffle plate 3 from deflecting during the movement caused by the impact force, a limiting member for limiting and fixing the driving gear 11 is provided on the side of the driving gear 11 away from the baffle plate 3, and the limiting member includes a slider 16, and the middle part of the upper end of the mounting rod 8 is vertically slidably connected to the slider 16 on the side away from the baffle plate 3, and the middle part of the lower end of the slider 16 is elastically connected to the bottom of the inner cavity of the mounting rod 8 through a spring, and the lower end of the slider 16 is fixedly connected to the end away from the driving gear 11. A fixed plate 18 is connected, a limit rod 17 is arranged on the side of the inner cavity of the slider 16 close to the driving gear 11, and the side wall of the limit rod 17 is fitted with the side wall of the inner cavity of the slider 16. A slide groove 20 is provided in the middle of the side of the slider 16 close to the fixed plate 18. A balance rod is slidably connected to the middle of the limit rod 17. The end of the balance rod away from the limit rod 17 is fixedly connected to the fixed plate 18. The horizontal width of the slide groove 20 is greater than the width of the balance rod. A spring is provided on the outer wall of the balance rod. A guide slope 1 is provided at the lower part of the inner cavity of the slider 16. 9, the guide slope 19 is inclined toward the direction where the fixed plate 18 is located. Due to the height difference between the two ends of the guide slope 19, when the slider 16 moves in the vertical direction, the end of the limit rod 17 close to the fixed plate 18 will also approach the fixed plate 18 along the guide slope 19 under the action of the elastic force, thereby changing the distance between the limit rod 17 and the fixed plate 18. When the lower end of the limit rod 17 is in contact with the bottom of the inner cavity of the slider 16, the distance between the limit rod 17 and the fixed plate 18 reaches the maximum value, and the limit rod 1 The end of the slider 16 away from the fixed plate 18 will also engage with the teeth of the driving gear 11, thereby limiting the position of the driving gear 11, and further limiting the position of the baffle 3. When the slider 16 moves downward, the limiting rod 17 will be driven horizontally along the balance bar to approach the position of the fixed plate 18 under the action of the elastic contraction of the spring. When the slider 16 moves upward, the limiting rod 17 will be pushed close to the position of the driving gear 11 through the cooperation of the guiding inclined surface 19 and the limiting rod 17, thereby limiting the position of the baffle 3.

[0032] The outer wall of the slider 16 is fixedly connected with guide rods on both sides, and the end of the guide rod away from the slider 16 passes through the outer wall of the mounting rod 8, and the outer wall of the guide rod is vertically slidably connected to the mounting rod 8. The inner cavity side wall of the mounting shell 21 is provided with a No. 1 groove 26 that slidably cooperates with the guide rod. In the process of the baffle 3 driving the mounting rod 8 to move horizontally, the guide rod will enter the No. 1 groove 26 and move horizontally along the No. 1 groove 26. In the process of the guide rod moving in the inner cavity of the No. 1 groove 26, the position of the guide rod remains unchanged in the vertical direction. The plane where the upper end of the slider 16 is located coincides with the plane where the upper end of the mounting rod 8 is located, that is, the plane where the upper end of the slider 16 is located is higher than the plane where the lower end of the rack 23 is located. When the mounting rod 8 drives the slider 16 horizontally close to the position of the rack 23, the lower end of the rack 23 will fit with the bottom of the inner cavity of the groove 9, and the side of the slider 16 away from the baffle 3 will contact the side of the rack 23 close to the baffle 3, thereby pushing the rack 23 to move horizontally in the direction away from the baffle 3 through the slider 16. At this time, the guide The rod moves horizontally along the No. 1 groove 26. The No. 2 groove 27 is provided at one end of the No. 1 groove 26 away from the baffle 3. When the guide rod moves to the connection between the No. 2 groove 27 and the No. 1 groove 26, the mounting rod 8 and the baffle 3 stop moving. Under the clamping cooperation between the clamping plate 25 and the clamping block 15, the position of the mounting rod 8 remains stationary. The slider 16 moves vertically downward under the action of the elastic force, thereby driving the guide rod to move vertically downward along the No. 2 groove 27. In the process of the slider 16 moving downward, the slider 16 and the rack 23 gradually move downward. Move away, after the slider 16 and the rack 23 are separated, the rack 23 moves horizontally toward the direction of the baffle 3 under the action of elastic force, and the lower end of the rack 23 will contact the outer wall of the driving gear 11, and the limiting rod 17 used to limit the driving gear 11 will also move horizontally away from the position of the driving gear 11, so that the driving gear 11 rotates counterclockwise after contacting the rack 23, thereby driving the driving gear 10 and the driven gear 13 to rotate counterclockwise, thereby driving the baffle 3 to rotate counterclockwise downward.

[0033] See also Fig. 9A ventilation slot 4 is provided on the side of the mounting block 5 away from the baffle 3, and a plurality of fans 6 are fixedly connected to the inner cavity of the ventilation slot 4 away from the baffle 3. A dust-proof net 7 is fixedly connected to the middle part of the inner cavity of the ventilation slot 4. By setting the fan 6 and the dust-proof net 7, after the explosion welding is completed, the fan 6 blows the airflow to drive the inner cavity of the shell 1, because the dust generated by the explosion welding moves toward the outer wall of the shell 1, and then the dust is intercepted by the dust-proof net 7, so as to avoid the dust from escaping after the explosion welding is completed and affecting the life safety of the staff. By setting the baffle 3 that automatically rotates after the explosion impact is buffered, the baffle 3 can release the blocking of the ventilation slot 4, so that the dust can pass through the interval between the rotating baffle 3 and the ventilation slot 4, enter the inner cavity of the ventilation slot 4 and be blocked by the dust-proof net 7, so as to avoid a large amount of dust from escaping from the shell 1, and also accelerate the dust settling speed, so as to avoid taking away the welded plate after the explosion welding is completed, spending a lot of time waiting for the dust to slowly settle.

[0034] See also Fig.10 A mounting cavity 36 is provided in the inner cavity of the mounting block 5 near the mounting shell 21, and a driven block 37 is horizontally slidably connected to the side of the inner cavity of the mounting cavity 36 away from the ventilation slot 4, and an electric push rod 38 is transmission-connected to the middle of the side of the inner cavity of the mounting cavity 36 near the ventilation slot 4, and the output end of the electric push rod 38 is fixedly connected to the middle of the driven block 37, and a first moving block 39 is horizontally slidably connected to the side of the upper part of the inner cavity of the mounting cavity 36 near the driven block 37, and a first traction rope 28 is fixedly connected to the middle of one end of the first moving block 39 near the driven block 37, and one end of the first traction rope 28 away from the first moving block 39 passes through the side walls of the mounting shell 21 and the outer shell 22 in turn and is fixedly connected to the middle of one end of the rack 23 away from the baffle 3, that is, when the rack 23 moves horizontally, it will not affect the position of the first moving block 39 through the first traction rope 28, and when the first moving block 39 moves horizontally, it will drive the rack 23 away from the baffle 3 through the first traction rope 28. The second moving block 40 is horizontally slidably connected to one side of the inner cavity of the mounting cavity 36 near the electric push rod 38. The second moving block 40 is further away from the position of the driven block 37 than the first moving block 39. Therefore, when the electric push rod 38 drives the driven block 37 to move horizontally, the driven block 37 will first push the first moving block 39 to move a certain distance before pushing the second moving block 40 to move horizontally. The second moving block 40 is fixedly connected to the second traction rope 29 at one end close to the driven block 37. The end of the second traction rope 29 away from the second moving block 40 passes through the outer wall of the mounting shell 21 and is fixedly connected to the middle part of the side of the card plate 25 away from the baffle 3. That is, when the baffle 3 needs to be reset, the driven block 37 is driven to move horizontally by the electric push rod 38, and the first moving block 39 is driven to move horizontally. When the first moving block 39 moves, the rack 23 is driven to move by the first traction rope 28, thereby causing the driving gear 11 to rotate clockwise.

[0035] See also Figure 8 The side wall of the mounting shell 21 is provided with a mounting groove 32, and a movable plate 33 is vertically slidably connected to the inner cavity of the mounting groove 32. The lower end of the movable plate 33 is elastically connected to the bottom of the inner cavity of the mounting groove 32 through a spring. A lifting rod 34 is fixedly connected to the side of the lower end of the mounting groove 32 close to the first groove 26. The end of the lifting rod 34 away from the mounting groove 32 is in contact with the inner cavity side wall of the second groove 27. The length of the lifting rod 34 is greater than the horizontal interval between the movable plate 33 and the second groove 27. The end of the rack 23 close to the baffle 3 is fixedly connected to the driving rod 30 on both sides. The inner cavity side wall of the mounting shell 21 is provided with a third groove 31. The driving rod 30 is fixedly connected to the inner cavity side wall of the mounting groove 32. The movable rod 30 is slidably matched with the No. 3 groove 31, and the outer wall of the driving rod 30 is slidably matched with the side wall of the outer shell 22. In the process of the slider 16 pushing the rack 23 to move, when the No. 1 groove 26 is in contact with the rack 23, the horizontal distance between the guide rod and the driving rod 30 is smaller than the distance between the side wall of the movable plate 33 and the side wall of the inner cavity of the installation groove 32 close to the No. 1 groove 26. Therefore, when the guide rod moves to the connection between the No. 1 groove 26 and the No. 2 groove 27, the driving rod 30 is not in contact with the movable plate 33 at this time. Therefore, the movable plate 33 remains stationary during the process of the slider 16 pushing the rack 23 to move.

[0036] The first movable block 39 drives the rack 23 to move through the first traction rope 28, and after the rack 23 drives the driving gear 11 to rotate clockwise, the driving rod 30 will contact the side wall of the movable plate 33 through the third groove 31. The side wall of the movable plate 33 is provided with a driven groove 35, and the driven groove 35 includes an inclined groove and a horizontal groove. The vertical height between the two ends of the inclined groove is the same as the vertical height of the second groove 27. The driving rod 30 enters the inclined groove through the third groove 31, thereby driving the movable plate 33 to move upward through the sliding cooperation between the inclined groove and the driving rod 30, and the movable plate 33 will drive the lifting rod 34 to move upward, thereby moving the guide rod located at the bottom of the inner cavity of the second groove 27 upward, so that the guide rod will return to the first groove 26, and through the cooperation of the guide inclined surface 19 and the limit rod 17, the limit rod 17 is pushed close to the driving gear 11 to limit and fix the driving gear 11 again, thereby returning to the vertical The baffle plate 3 in the straight state is limited and fixed, and with the horizontal movement of the driving rod 30, the driving rod 30 will also enter the horizontal groove from the inclined groove. Through the sliding cooperation between the horizontal groove and the driving rod 30, the position of the lifting rod 34 can be kept fixed, so that the guide rod is stably located in the inner cavity of the No. 1 groove 26. When the driving rod 30 enters the horizontal groove, the driven block 37 also contacts the second moving block 40, and pulls the card plate 25 away from the card block 15 through the second traction rope 29, thereby releasing the limiting effect on the mounting rod 8, so that the mounting rod 8 and the baffle plate 3 are reset under the action of elastic force, thereby driving the guide rod in the inner cavity of the No. 1 groove 26 away from the position of the mounting cavity 36, so that the position of the baffle plate 3 is kept fixed during the resetting process, and when the electric push rod 38 pushes the driven block 37 away from the position of the ventilation groove 4, the rack 23, the moving plate 33 and the card plate 25 are all reset under the action of elastic force.
