Description

Technical Field

[0001] The utility model relates to the technical field of fireproof covers, in particular to a heat-insulating fireproof cover for an exhaust system. Background Art

[0002] The heat-insulating fire hood allows exhaust gas to pass through while preventing flames and sparks from escaping, providing fire protection and heat insulation. The top of the fire hood is equipped with heat sinks made of an intumescent material such as graphite, which are designed with air holes. When exposed to heat, the heat sinks expand and automatically seal the air holes, thereby restricting air ingress, controlling the combustion area, and preventing the spread of fire. High-temperature resistance: Because the top of the fire hood is directly exposed to high-temperature exhaust gas, the selected material must be able to withstand high temperatures and thermal shock to ensure that it will not damage or lose its function even under extreme conditions.

[0003] At present, most of the fireproof covers in use on the market are wrapped around the circumference of the exhaust pipe to insulate the surface of the exhaust pipe and prevent people from getting burned. Therefore, during use, multiple people are required to cooperate to lay the fireproof cover on the circumference of the exhaust pipe, and then use cable ties to tie it up to prevent the fireproof cover from falling off.

[0004] However, due to the installation height of the exhaust pipe and the diameter of the exhaust system, it is inconvenient for personnel to install it, which makes it easy for it to rebound during the tightening process, and thus makes it impossible for the fireproof cover to fit tightly with the exhaust system.

[0030] 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 embodiments 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 making creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1 to 3 , the utility model provides a technical solution:

[0032] An exhaust system heat insulation and fireproof cover, comprising an exhaust pipe 1, characterized in that: two first arc-shaped rings 31 are provided on the outer circumferential surface of the exhaust pipe 1;

[0033] A screw rod 41 is rotatably mounted between the front ends of the left and right first arc-shaped rings 31. A main motor 4 is provided on the left side of the screw rod 41. The output shaft of the main motor 4 is fixedly connected to the screw rod 41. A slide rod 42 is fixedly mounted between the rear ends of the two first arc-shaped rings 31.

[0034] A winding assembly 5 is slidably provided on the outer circumferential surface of the exhaust pipe 1;

[0035] The winding assembly 5 includes a second arc-shaped ring 51 slidably mounted on the circumferential surface of the screw 41 and the sliding rod 42, and a second double-sided gear ring 55 is slidably mounted inside the second arc-shaped ring 51. The right sides of the second arc-shaped ring 51 and the second double-sided gear ring 55 are both provided with arc-shaped grooves and a second sliding block 58 is slidably mounted thereon. The arc-shaped groove on the right side of the second double-sided gear ring 55 is located on the inner side of the arc-shaped groove on the right side of the second arc-shaped ring 51. A double-headed motor 57 is fixedly mounted on the rear of the second sliding block 58, and a tightening rod 561 is fixedly mounted on the output shaft of the double-headed motor 57.

[0036] A third motor 53 is fixedly mounted on the left side of the front end of the second arc-shaped ring 51, and a third gear 54 is fixedly mounted on the output shaft of the third motor 53. The third gear 54 meshes with the outer side surface of the second double-sided gear ring 55. A fourth gear 56 is fixedly mounted on the left output shaft of the main motor 4. The fourth gear 56 meshes with the inner side of the second double-sided gear ring 55. A second inner tooth 52 is provided on the inner side of the second arc-shaped ring 51, and the fourth gear 56 also meshes with the second inner tooth 52.

[0037] By adopting the above technical solution, when in use, first, under the drive of the mounting ring 2, the entire device is installed on the circumferential surface of the exhaust system, and the bolts at the opening of the mounting ring 2 are used to fix the entire structure so that the device will not fall off. At this time, the first motors 32 on the left and right sides are started, and the output shaft of the first motor 32 will rotate with the first gear 33, thereby driving the first double-sided gear ring 34 to slide inside the first arc ring 31.

[0038] Thereby, the first arc ring 31 and the first double-sided gear ring 34 can be combined into a circular ring structure, and then the cover rod 36 can be rotated along the exhaust pipe 1 under the action of the dual-axis motor 351. After completion, the third motor 53 is started, and the output shaft of the third motor 53 will drive the third gear 54 to rotate, so that the second double-sided gear ring 55 can be rotated, so that the second arc ring 51 and the second double-sided gear ring 55 are combined into a circular ring structure. At this time, the double-headed motor 57 is started, and the output shaft of the double-headed motor 57 will drive the fourth gear 56 to rotate along the second inner teeth 52 and the inner tooth groove of the second double-sided gear ring 55, and under the action of the second sliding block 58, the fourth gear 56 will not fall off.

[0039] When the fourth gear 56 rotates, it can work synchronously with the tightening rod 561, so that the rope on the circumferential surface of the tightening rod 561 can be wound around the outer surface of the fireproof cover, and finally the wound rope can be tightened under the action of the double-headed motor 57; thereby, the manual tightening can be eliminated and the situation of insufficient manual tightening can be avoided. Moreover, after tightening, due to the action of the double-headed motor 57, the rope will not rebound, thereby ensuring the tightness of the wrapping.

[0040] Specifically, such as Figures 2 to 4 As shown, the mounting ring 2 is fixedly mounted on the end faces of the two left and right first arc-shaped rings 31 that are away from each other, the first internal teeth 311 are provided inside the two first arc-shaped rings 31, the first motor 32 is fixedly mounted on the outer side of the opening at the end away from the front end of the two left and right first arc-shaped rings 31, and the first gear 33 is fixedly mounted on the output shaft of the two first motors 32.

[0041] A first double-sided gear ring 34 is slidably installed inside the two first arc-shaped rings 31, and the two first gears 33 are meshed with the outer side surfaces of the adjacent first double-sided gear rings 34. A first sliding block 37 with a U-shaped structure is slidably installed on the adjacent end surfaces of the two first arc-shaped rings 31 and the first double-sided gear rings 34. An arc-shaped groove is provided on the adjacent end surfaces of the two first arc-shaped rings 31 and the first double-sided gear rings 34, and the first sliding block 37 is slidably connected to the inside of the arc-shaped groove. The arc groove on the adjacent end surface of the two first double-sided gear rings 34 is located on the inner side of the adjacent first arc-shaped ring 31.

[0042] A dual-axis motor 351 is fixedly installed on the rear part of the two first sliding blocks 37, and a cover rod 36 rotates on the output shaft between the two dual-axis motors 351. A second gear 35 is fixedly installed on the output shaft at the end away from the two dual-axis motors 351, and the two second gears 35 are engaged with the inner side tooth grooves of the adjacent first internal teeth 311 and the first double-sided gear ring 34.

[0043] By adopting the above technical solution, when in use, as mentioned above, the first arc ring 31 and the first double-sided gear ring 34 are combined into a circular ring structure. At this time, the dual-axis motor 351 at the left and right ends drives the second gear 35 connected to the output shaft to rotate along the first inner teeth 311 and the inner tooth grooves of the first double-sided gear ring 34, and under the action of the first sliding block 37, it can prevent the second gear 35 from being unable to engage, thereby ensuring the movement of the second gear 35. When the second gear 35 rotates, it can drive the cover rod 36 between the two second gears 35 to rotate around the exhaust pipe 1, and during the process of rotating, the fireproof cover can be attached to the outer circumferential surface of the exhaust pipe 1.

[0044] After the second gear 35 circles the exhaust pipe 1 for one circle, the fireproof cover is evenly laid on the outer circumferential surface of the exhaust pipe 1. At this time, the second gear 35 continues to circle under the action of the dual-axis motor 351, so as to tighten the fireproof cover, so as to ensure that the fireproof cover can fit more tightly after subsequent bundling, thereby ensuring the installation of the fireproof cover; with the cooperation of the above-mentioned multiple structures, the automatic laying and tightening operation of the fireproof cover is completed, saving the difficulty of manual operation, saving time and tedious installation.

[0045] Working principle: First, under the action of the mounting ring 2, the entire device can be fixedly installed on the circumferential surface of the exhaust pipe 1, and under the action of the first motor 32 and the first gear 33, the first arc ring 31 and the first double-sided gear ring 34 can be combined into a ring structure.

[0046] Then, under the action of the dual-axis motor 351 and the second gear 35, the cover rod 36 can move in a circle around the exhaust pipe 1, thereby completing the laying and tightening operation of the fireproof cover.

[0047] Secondly, under the action of the third motor 53 and the third gear 54, the second arc ring 51 and the second double-sided gear ring 55 can be combined into a ring structure.

[0048] Then, under the action of the double-headed motor 57 and the fourth gear 56 , the tightening rod 561 can perform a binding operation on the fireproof cover.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
