Strong corrosion resistance: Inorganic fiber materials have excellent corrosion resistance and can adapt to various harsh environments, extending the service life of the duct. Light weight but high strength, while ensuring the strength of the duct structure, the weight of the duct is reduced as much as possible, easy to install and maintain, and simple installation: Reasonable design, relatively simple and quick installation process, can reduce construction costs and time.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1, as Figure 1 and Figure 2 As shown, a steel inorganic fiber fireproof air duct punching device includes a device shell 1, support legs 2 are fixedly connected at the four corners of the lower end of the device shell 1, a control box 3 is fixedly installed on the left front end of the device shell 1, a punching component 4 is slidably connected to the right end of the device shell 1, a clamping inner support component 5 is arranged at the upper end of the device shell 1, and a pretreatment component 6 is commonly arranged on the left part of the inner surface of the device shell 1 and the middle part of the upper end.

[0033] During the implementation of this embodiment, the circular steel inorganic fiber fireproof air duct that needs to be punched is placed on the clamping inner support component 5, and the control box 3 is operated to make the clamping inner support component 5 support the inner ring of the circular steel inorganic fiber fireproof air duct, and then rotate it after the support. During the rotation, the dust and oil attached to the outer surface of the circular steel inorganic fiber fireproof air duct are treated by the pretreatment component 6. After the treatment, the clamping inner support component 5 is used to clamp and fix it, and the punching component 4 is used to punch holes. At the same time, when changing the punching position, the clamping inner support component 5 is rotated, and after the rotation, it is clamped and fixed, and the punching component 4 is used again to punch holes.

[0034] The punching component 4 mentioned above is a mature punching technology means in the prior art, and is a mature punching equipment in the prior art. In this scheme, it is used to punch holes in circular steel inorganic fiber fireproof air ducts, and its structure and principle will not be explained again.

[0035] The control box 3 mentioned above is a mature control means and a mature control device in the prior art. In this solution, the control functions thereof are utilized, and its structure and principle are not further elaborated.

[0036] Specifically, in order to realize the rotation of the circular steel inorganic fiber fireproof air duct, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9In this embodiment, the clamping inner support assembly 5 includes two rectangular holes 51 opened at the upper end of the device housing 1, a circular groove 56 is opened in the middle of the upper end of the device housing 1, and a clamping mechanism 52 is commonly arranged on the inner surfaces of the two rectangular holes 51, a rotating mechanism 53 is arranged on the middle side of the rear part of the upper end of the device housing 1, an inner support mechanism 54 is arranged on the inner surface of the rotating mechanism 53, and a supporting mechanism 55 is arranged on the inner surface of the circular groove 56.

[0037] For further information, see Figure 4 and Figure 7 In this embodiment, the internal support mechanism 54 includes an electric telescopic rod 541 fixedly connected to the rear part of the front space of the inner surface of the round rod 538, a circular ring block 543 is fixedly connected to the front of the outer surface of the round rod 538, and a cross block 542 is fixedly connected to the front end of the electric telescopic rod 541. The inner surfaces of the circular ring block 543 and the cross block 542 are both rotatably connected with four support rods 544 distributed in an annular manner at equal distances. The outer surfaces of the two support rods 544 on the same side are rotatably connected with a concave plate 545 together, and the ends of the four concave plates 545 away from the cross block 542 are fixedly installed with an electromagnetic block 546.

[0038] During the implementation process, after the circular steel inorganic fiber fireproof air duct is placed, the electric telescopic rod 541 is started, so that the electric telescopic rod 541 drives the cross block 542 to move forward. Due to the forward push of the cross block 542, the support rod 544 on the cross block 542 rotates, thereby driving the support rod 544 on the circular block 543 to rotate, pushing the concave plate 545 to expand in all directions, so that the electromagnetic block 546 can be tightly attached to the inner surface of the circular steel inorganic fiber fireproof air duct, so that the circular steel inorganic fiber fireproof air duct is supported from the inside, and can adapt to circular steel inorganic fiber fireproof air ducts with different inner diameters, thereby improving the adaptability of the device housing 1.

[0039] For further information, see Figure 4 and Figure 6 In this embodiment, the rotating mechanism 53 includes a rotating rod 531 fixedly connected to the left output end of the dual-axis motor 524 through a coupling, a transmission rod 1 532 is rotatably connected to the left rear end of the device housing 1 and extends to the right end of the device housing 1, and a transmission rod 2 534 is rotatably connected to the middle side of the upper rear end of the device housing 1 and extends to the upper inner surface of the device housing 1, and a pulley group 2 533 is fixedly connected to the left outer surface of the transmission rod 1 532 and the outer surface of the rotating rod 531, a fixing plate 536 is fixedly connected to the rear upper end of the device housing 1, and a round rod 538 is rotatably connected to the inner surface of the fixing plate 536, a gear group 1 535 is fixedly connected to the middle outer surface of the transmission rod 1 532 and the lower outer surface of the transmission rod 2 534, and a gear group 2 537 is fixedly connected to the rear outer surface of the round rod 538 and the upper outer surface of the transmission rod 2 534.

[0040] During the implementation process, after the circular steel inorganic fiber fireproof air duct is supported internally, since the inner surface of the circular steel inorganic fiber fireproof air duct is a steel plate, the electromagnetic block 546 is started at this time, so that the electromagnetic block 546 can electromagnetically adsorb the circular steel inorganic fiber fireproof air duct. When the circular steel inorganic fiber fireproof air duct needs to be rotated, the left end output end of the dual-axis motor 524 is started at this time to drive the rotating rod 531 to rotate, and then under the transmission action of the pulley group 2 533, the transmission rod 1 53 2 is rotated, and at the same time, under the cooperation of the transmission rod 2 534, the gear set 1 535 and the gear set 2 537, the round rod 538 is rotated on the inner surface of the fixed plate 536, so that the entire inner support mechanism 54 is rotated to drive the circular steel inorganic fiber fireproof air duct to rotate, so that when the circular steel inorganic fiber fireproof air duct is pretreated on the outer surface or when the punching position is changed, the outer surface position of the circular steel inorganic fiber fireproof air duct is changed, so that it can be convenient for the staff to use.

[0041] The electromagnetic block 546 mentioned above is a mature magnetic attraction component in the prior art. The present solution utilizes the fact that when current passes through the wire, the movement of electrons on the wire forms a magnetic field surrounding the wire, and this magnetic field can attract magnetic objects, such as iron or steel.

[0042] The belt pulley group 2 533 mentioned above is composed of two belt pulleys and a belt.

[0043] The gear set 1 535 and the gear set 2 537 mentioned above are both composed of two bevel gears.

[0044] For further information, see Figure 3 , Figure 4 and Figure 5 In this embodiment, the clamping mechanism 52 includes two threaded rods 521 that penetrate the right end of the device housing 1 and extend to the left end of the device housing 1 and are rotatably connected. The outer surfaces of the two threaded rods 521 are symmetrically threaded with sliders 522 that are slidably connected to the inner surface of the rectangular hole 51. The left parts of the outer surfaces of the two threaded rods 521 are commonly fixedly connected with a pulley set 525. The left end of the rear threaded rod 521 is fixedly connected with a dual-axis motor 524 that is fixedly connected to the left end of the device housing 1. The upper ends of the four sliders 522 are fixedly connected with clamping plates 523.

[0045] During the implementation process, when the circular steel inorganic fiber fireproof air duct is rotated and then punched, the right end output end of the dual-axis motor 524 is started, so that the right end output end of the dual-axis motor 524 drives the threaded rod 521 at the rear to rotate, and under the transmission action of the pulley group 525, the threaded rod 521 at the front is rotated, so that the sliders 522 on the two threaded rods 521 can move closer to the middle, and then drive the clamping plate 523 to fix the rotated circular steel inorganic fiber fireproof air duct, so as to avoid the circular steel inorganic fiber fireproof air duct from changing its position during the punching operation, causing the punching to deviate from the set position.

[0046] The thread grooves on the outer surface of the threaded rod 521 are symmetrically and reversely distributed.

[0047] The pulley assembly 525 mentioned above is composed of two pulleys and a belt.

[0048] The dual-axis motor 524 mentioned above is a mature driving technology device in the prior art, and is a mature driving technology means in the prior art. This solution utilizes it to rotate independently on both sides, and the number of positive and negative rotations on both sides can be adjusted and controlled separately, and it can stop in time after rotating to the set number of circles.

[0049] For further information, see Figure 3 , Figure 4 , Figure 8 and Fig. 9 In this embodiment, the supporting mechanism 55 includes a piston 552 slidably connected to the space at the rear of the inner surface of the round rod 538, a connecting rod 553 fixedly connected to the front end of the piston 552 is fixedly connected to the rear end of the cross block 542, the connecting rod 553 is slidably connected to the round rod 538, a round hole 551 is opened at the rear of the outer surface of the round rod 538, a circular ring block 558 fixedly connected to the rear end of the fixed plate 536 is rotatably connected to the outer surface of the round rod 538 at the circular hole 551, a circular groove block 554 is fixedly connected to the inner surface of the circular groove 56, a supporting plate 555 is slidably connected to the inner surface of the circular groove block 554, a plurality of balls 556 are arranged on the inner surface of the supporting plate 555, and a connecting pipe 557 is fixedly connected to the rear of the inner surface of the circular groove block 554.

[0050] As can be seen from the above, when the electric telescopic rod 541 pushes the cross block 542 forward, the cross block 542 drives the connecting rod 553 to move forward, and then the piston 552 can be pulled to slide on the inner surface of the rear space of the round rod 538, so that the piston 552 can extract the hydraulic oil in the circular groove block 554 through the circular hole 551 and the connecting pipe 557, and then the height of the support plate 555 is lowered, so that the ball 556 on the support plate 555 can support the circular steel inorganic fiber fireproof air duct, so as to avoid the problem of excessive force on the internal support mechanism 54 after the internal support, and will not affect the rotation of the circular steel inorganic fiber fireproof air duct. At the same time, the descending height of the support plate 555 can follow the inner diameter of the circular steel inorganic fiber fireproof air duct to achieve automatic follow-up adjustment, thereby facilitating the rotation operation.

[0051] Embodiment 2: Based on Embodiment 1, this embodiment adds a pretreatment component 6 for pretreatment of the outer surface of the steel inorganic fiber fireproof air duct before punching, so as to achieve the purpose of pretreatment of the outer surface of the steel inorganic fiber fireproof air duct before punching.

[0052] Specifically, in order to pre-treat the outer surface of the steel inorganic fiber fireproof air duct before drilling, refer to Figure 4 , Fig.10 and Fig.11 In this embodiment, the pretreatment component 6 includes a placement box 61 fixedly connected to the left portion of the inner surface of the device housing 1, an adaptation mechanism 62 is provided at the left end of the support plate 555, a cleaning mechanism 63 is provided at the upper end of the adaptation mechanism 62, and a wiping mechanism 64 is provided at the upper end of the cleaning mechanism 63.

[0053] For further information, see Figure 3 , Figure 4 and Fig.10 In this embodiment, the adaptation mechanism 62 includes a slide groove 621 opened on the left side of the middle upper end of the device housing 1, a spring telescopic rod 622 is fixedly connected to the left inner surface of the slide groove 621, a rectangular block 623 slidably connected to the slide groove 621 is fixedly connected to the right end of the spring telescopic rod 622, an arc block 1 624 is fixedly connected to the right upper end of the rectangular block 623, and an arc block 2 625 is fixedly connected to the left end of the support plate 555.

[0054] For further information, see Figure 4 and Fig.10 In this embodiment, the cleaning mechanism 63 includes an L-shaped plate 631 fixedly connected to the left upper end of the rectangular block 623, a concave frame 632 is fixedly connected to the right end of the L-shaped plate 631, a sponge block 633 is fixedly installed on the inner surface of the concave frame 632, a connecting pipe 634 is fixedly connected to the upper rear side of the inner surface of the placement box 61 and extends to the upper inner surface of the concave frame 632, and a water pump 635 is fixedly connected to the lower end of the connecting pipe 634.

[0055] During the implementation process, the downward movement of the support plate 555 allows the support plate 555 to drive the arc block 2 625 to move downward, thereby causing the arc block 2 625 to squeeze the arc block 1 624, and the arc block 1 624 pushes the rectangular block 623 to move leftward on the inner surface of the slide groove 621, so that the rectangular block 623 is in a compressed state by squeezing the spring telescopic rod 622, and drives the concave frame 632 on the L-shaped plate 631 to move leftward, so that the sponge block 633 moves, and circular steel inorganic fiber fireproof wind turbines with different inner diameters can be used. The outer surface of the tube is tightly attached, and during the process of tightly attaching, the water pump 635 is started so that the cleaning liquid in the extraction box 61 of the water pump 635 enters the sponge block 633 through the connecting pipe 634, and the circular steel inorganic fiber fireproof air duct is driven to rotate by the cooperation of the rotating mechanism 53 and the internal support mechanism 54, so that the sponge block 633 can clean the dust and oil attached to the outer surface of the circular steel inorganic fiber fireproof air duct, thereby improving the adhesion and sealing of the circular steel inorganic fiber fireproof air duct when drilling.

[0056] The spring telescopic rod 622 mentioned above is composed of a spring and a telescopic rod.

[0057] For further information, see Figure 4 and Fig.11 In this embodiment, the wiping mechanism 64 includes a fixed block 641 fixedly connected to the middle of the upper end of the concave frame 632, one end of the fixed block 641 is fixedly connected to a rectangular plate 642, and a cleaning cloth 643 is attached to one side of the rectangular plate 642 by Velcro.

[0058] During the implementation process, after the circular steel inorganic fiber fireproof air duct is cleaned by the sponge block 633, the cleaning liquid left on the outer surface of the circular steel inorganic fiber fireproof air duct can be wiped by the cleaning cloth 643 while rotating, so that the remaining cleaning liquid can be removed without affecting the punching operation of the circular steel inorganic fiber fireproof air duct.

[0059] Working process: When in use, the circular steel inorganic fiber fireproof duct is placed on the inner support mechanism 54. At this time, the inner support mechanism 54 performs inner support operation on the circular steel inorganic fiber fireproof duct. At the same time, during the inner support operation, the jacking mechanism 55 can perform jacking operation on the circular steel inorganic fiber fireproof duct to avoid unbalanced force on the inner support mechanism 54. At this time, the circular steel inorganic fiber fireproof duct is driven to rotate by the rotating mechanism 53, and during the rotation process, the dust and oil on the outer surface of the circular steel inorganic fiber fireproof duct are processed through the cooperation of the adaptation mechanism 62, the cleaning mechanism 63 and the wiping mechanism 64, and after pre-treatment, it is fixed by the clamping mechanism 52, and then punching is performed.
