When the spiral staircase is installed on the outer surface of the reactor, it is usually fixed by welding. This fixing method can easily damage the anti-rust layer on the outer surface of the reactor, resulting in a decrease in the corrosion resistance of the reactor. In order to facilitate the installation of the spiral staircase, it is necessary to draw holes on the outer surface of the reactor during production for subsequent assembly and fixing of the spiral staircase.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-10 The present invention provides a technical solution: a hole-pulling device for a small reactor cylinder, comprising a damping plate 1, a reactor cylinder 16, a hole puller 18, a hole-pulling knife 19 and a restraining chuck 21. A plurality of docking holes 20 are provided on the outer surface of the reactor cylinder 16, and the plurality of docking holes 20 are equidistantly distributed on the outer surface of the reactor cylinder 16 in a spiral shape. A fixed frame 2 is installed at the top of the damping plate 1 near the front edge, and a U-shaped support platform 3 is fixed at the top of the damping plate 1 near the rear edge. The outer surface of the reactor cylinder 16 near the rear edge is slidably fitted with the inner wall of the U-shaped support platform 3, and the restraining chuck 21 is clamped between the inner walls of the reactor cylinder 16 near the front edge. Fixed plates 4 are installed on both the front and rear sides of the fixed frame 2, and a distribution component for intermittently rotating the reactor cylinder 16 is provided on the fixed plate 4 located on the front side of the fixed frame 2.

[0034] A movable component is arranged between the inner walls on both sides of the fixed frame 2 to drive the hole puller 18 and the hole puller 19 to move up and down. A base 5 is arranged on the front side of the shock-absorbing plate 1. A motor 13 is fixed on the top of the base 5. A V-shaped rod 22 is fixed on the output end of the motor 13. A lever 33 is fixed on the front side of one end of the V-shaped rod 22. The other end of the V-shaped rod 22 is rotatably connected to the push rod 12 at the rear side.

[0035] The effect achieved is that, by providing a distribution component, a movable component and an adjustment component, it is helpful to accurately position the spirally distributed hole pulling parts during the process of pulling holes in the docking holes 20 on the outer surface of the reactor cylinder 16, the distribution component can be used to intermittently adjust the angle of the reactor cylinder 16, and the movable component can be used to drive the hole puller 18 to pull holes after the distribution component has adjusted the angle of the reactor cylinder 16, wherein the distribution component and the movable component work to cooperate with each other and move alternately, and when the movable component drives the hole puller 18 to move up and down, each reciprocating movement will trigger the adjustment component to change the position of the hole puller 18, and the distribution component can be used to accurately pull holes one by one in cooperation with the distribution component, fix the lever 33 to the front side of one end of the V-shaped rod 22 and rotatably connect the push rod 12 to the rear side of the other end of the V-shaped rod 22, so that the V-shaped rod 22 will not interfere with each other when driving the movable component through the push rod 12 and driving the distribution component through the lever 33 during the rotation process.

[0036] like Figure 1 , Figure 4 and Figure 6 As shown, the shifting assembly includes an adjusting disk 14, the outer surface of which is equidistantly provided with a plurality of shifting openings 15 extending to the front and rear sides along the circumferential direction, the shifting rod 33 is slidably engaged inside the shifting openings 15, a first rubber damping sleeve 24 is fixed between the opposite sides of the two fixed plates 4, a rotating shaft 23 is arranged between the inner walls of the first rubber damping sleeve 24, one end of the rotating shaft 23 slides through the outer side of the fixed plate 4 located on the front side of the fixed frame 2, one end of the rotating shaft 23 is fixedly connected to the adjusting disk 14, the other end of the rotating shaft 23 slides through the outer side of the fixed plate 4 located on the rear side of the fixed frame 2, and the other end of the rotating shaft 23 is fixedly connected to the constraint chuck 21.

[0037] The effect achieved is that when the shifting assembly is working, the V-shaped rod 22 is driven to rotate by the motor 13. When the lever 33 on the front side of one end of the V-shaped rod 22 is engaged with the shifting hole 15 on the adjusting disk 14, the adjusting disk 14 can be driven to rotate, thereby driving the reaction kettle cylinder 16 to rotate. When the lever 33 and the shifting hole 15 on the adjusting disk 14 are separated from each other, since the rotating shaft 23 is arranged between the inner walls of the first rubber damping sleeve 24, and the first rubber damping sleeve 24 is made of rubber, a certain friction constraint force can be generated on the rotating shaft 23, so that the rotating shaft 23 can be fixed inside the first rubber damping sleeve 24 without being rotated by a large external force, preventing the reaction kettle cylinder 16 from rotating during the process of pulling a hole in the reaction kettle cylinder 16 after the lever 33 and the shifting hole 15 on the adjusting disk 14 are separated from each other.

[0038] like Figure 1 , Figure 2 and Figure 4As shown, the movable component includes a cantilever plate 17, a through hole 9 extending from the top to the bottom is opened at the top of the cantilever plate 17, a transmission chamber 25 is opened inside the cantilever plate 17 near the front edge, an adjustment component that can intermittently and equidistantly change the position of the hole puller 18 is arranged inside the transmission chamber 25, one end of the cantilever plate 17 extends above the U-shaped support platform 3, guide grooves 6 are opened on the inner walls on both sides of the fixed frame 2, guide rods 7 are fixed between the inner top surfaces of the two guide grooves 6 and the ground, guide blocks 8 are fixed on the outer surfaces of both sides of the cantilever plate 17 near the front edge, the two guide blocks 8 are both located inside the guide grooves 6, and the two guide blocks 8 are both slidably connected to the outer surfaces of the guide rods 7, one end of the push rod 12 is rotatably connected to the front side of the cantilever plate 17, a screw rod 10 is rotatably connected between the inner walls on both sides of the through hole 9, the hole puller 18 is located inside the through hole 9 and is slidably connected to the outer surface of the screw rod 10, and the hole puller 18 is arranged at the bottom of the hole puller 18.

[0039] The effect achieved is that when the movable component is working, the V-shaped rod 22 is driven to rotate by the motor 13. Since the front side of the cantilever plate 17 and the rear side of the other end of the V-shaped rod 22 are connected by the push rod 12, the cantilever plate 17 can be driven to move up and down by the push rod 12 when the V-shaped rod 22 rotates, and works intermittently with the distribution component during the movement. When the distribution component rotates the reactor cylinder 16, the cantilever plate 17 is in an ascending state. When the distribution component fixes the reactor cylinder 16, the cantilever plate 17 is in a descending state to perform hole pulling operation. At the same time, when the cantilever plate 17 moves up and down, the mutual cooperation of the guide rod 7 and the guide block 8 can make the sliding of the cantilever plate 17 more stable.

[0040] like Figure 1 , Figure 4 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the adjustment assembly includes a screw rod 11, which is mounted on the inner top surface of the fixed frame 2, and the outer surface of the screw rod 11 is a smooth surface near the bottom edge. The bottom of the screw rod 11 slides through the bottom of the cantilever plate 17, and one end of the screw rod 10 slides through the inside of the transmission chamber 25. A first annular groove 26 is provided on the inner top surface of the transmission chamber 25. The outer surface of the screw rod 11 is located in the inner thread of the transmission chamber 25 and is connected with a first bevel gear 27. The top of the first bevel gear 27 is slidably engaged in the first annular groove 26. A second annular groove 28 is provided between the inner walls of the transmission chamber 25 near one end of the screw rod 10. A first annular plate 29 is rotatably connected between the inner walls of the second annular groove 28, and one end of the first annular plate 29 is rotatably connected. A second bevel gear 30 is fixed on the side, and the second bevel gear 30 is meshed with the first bevel gear 27. One end of the screw rod 10 is located in the transmission chamber 25 and a second annular plate 31 is fixed thereto. A plurality of wedge-shaped grooves 35 are equidistantly provided on the outer surface of one side of the second annular plate 31 along the circumferential direction. A plurality of spring paddles 34 are equidistantly fixed on the outer surface of the other side of the first annular plate 29 along the circumferential direction. One ends of the plurality of spring paddles 34 extend to the inside of the wedge-shaped grooves 35 respectively. The inner walls on one side of the plurality of wedge-shaped grooves 35 are inclined to the bottom surface, and the inner walls on the other side are vertical to the bottom surface. A second rubber damping sleeve 32 is sleeved on the outer surface of the screw rod 10, and the second rubber damping sleeve 32 is fixed between the transmission chamber 25 and the through-port 9.

[0041] The effect achieved is that when the adjustment component is working, when the cantilever plate 17 is in a descending state and drives the hole puller 18 to pull holes in the reactor cylinder 16, the first bevel gear 27 rotates under the action of the screw 11, which will drive the second bevel gear 30 to rotate. At this time, the spring paddle 34 on the first annular plate 29 rotates toward the inclined surface of the wedge-shaped groove 35, so the spring paddle 34 will slide on the outer surface of the second annular plate 31 under the guidance of the inclined surface, and will not drive the second annular plate 31 to rotate. When the cantilever plate 17 is in an ascending state and drives the hole puller 18 to reset, the first bevel gear 27 rotates under the action of the screw 11, which will drive the second bevel gear 30 to rotate. At this time, the spring paddle 34 on the first annular plate 29 rotates toward the vertical surface of the wedge-shaped groove 35. The spring pick 34 will be engaged in the wedge-shaped groove 35 under the obstruction of the vertical surface, thereby driving the second annular plate 31 to rotate. The rotation of the second annular plate 31 will drive the screw rod 10 to rotate, thereby driving the hole puller 18 to change its position. The second rubber damping sleeve 32 is fixed between the transmission cavity 25 and the through-hole 9 and is sleeved on the outer surface of the screw rod 10, which can apply a certain damping force to the screw rod 10. When the force driving the screw rod 10 is less than the damping force, the screw rod 10 cannot be driven to rotate. The outer surface of the screw rod 11 is set to a smooth surface near the bottom edge, which can prevent the bottom of the hole pulling knife 19 from being still located in the docking hole 20 after the hole pulling is completed. When the movable component rises and the adjusting component is triggered to change the position of the hole puller 18, a collision occurs between the bottom of the hole pulling knife 19 and the inside of the docking hole 20.

[0042] Working principle: First, start the motor 13, and the motor 13 drives the V-shaped rod 22 to rotate. When the lever 33 on the front side of one end of the V-shaped rod 22 engages with the lever 15 on the adjusting disk 14, the adjusting disk 14 can be driven to rotate, so as to change the angle of the reactor cylinder 16. When the adjusting disk 14 rotates, the cantilever plate 17 will be pushed upward through the push rod 12. When the cantilever plate 17 moves upward, the first bevel gear 27 rotates under the action of the screw 11, which will drive the second bevel gear 30 to rotate. At this time, the direction of rotation of the spring paddle 34 on the first annular plate 29 is toward the vertical surface of the wedge-shaped groove 35, so the spring paddle 34 is rotated. 4 will be engaged in the wedge-shaped groove 35 under the obstruction of the vertical surface, thereby driving the second annular plate 31 to rotate. The rotation of the second annular plate 31 will drive the screw rod 10 to rotate, thereby driving the hole puller 18 to change its position. When the lever 33 and the lever opening 15 on the adjusting disk 14 are separated from each other, the cantilever plate 17 is pulled downward by the push rod 12, thereby driving the hole puller 18 and the hole puller 19 to pull the docking hole 20 on the reactor cylinder 16. When pulling the hole, the restraining force generated between the first rubber damping sleeve 24 and the rotating shaft 23 can restrain the rotating shaft 23 to prevent the reactor cylinder 16 from rotating when pulling the hole.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
