Description

Technical Field

[0001] This invention relates to the field of duct support and installation technology, and in particular to an angle steel flange duct connection device. Background Technology

[0002] In actual duct support installation, the duct flanges need to be connected and supported on the wall. The support strength and flange connection quality directly affect the sealing of the subsequent connection. Brackets are usually used for support. However, if the distance between the wall and the duct is too close during duct connection, it will be difficult to install the bolts. Current duct connection devices are not convenient for checking the stability of the angle steel flange support before connecting and tightening. At the same time, traditional bracket supports are usually supported on the duct below, which is not convenient for assisting in the protection of the flange. In the subsequent bolt installation work, it is not convenient to restrict the sequence of bolt installation, and it is difficult for people to accurately judge with the naked eye in a confined space.

Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1 to 9 :

[0033] This invention proposes a duct connection device for angle steel flanges, including a laying support 1, with an electric tightening part 2 above the laying support 1; the laying support 1 is used to position and clamp the duct joint flange; a locking part 3 is installed on the electric tightening part 2; the locking part 3 is used to lock the electric tightening part 2; a flange adapter 4 is installed on the electric tightening part 2; a sequence limiting part 5 is installed on the flange adapter 4; the sequence limiting part 5 is used to prevent screws from being missed; the laying support 1 includes: a pipe clamping frame 101, a limiting groove 1011, and a positioning bolt 102; two pipe clamping frames 101 are provided, and the two pipe clamping frames 101 are connected by a hinge; two through holes are opened at the bottom of the lower pipe clamping frame 101; the lower pipe clamping frame 101 is used to support the duct by being bolted to the wall; each of the two pipe clamping frames 101 is provided with a limiting groove 1011; the limiting grooves 1011 on the two pipe clamping frames 101 are used to clamp the angle steel flange.

[0034] In this embodiment, the laying support 1 further includes: a position switch 103 and an indicator light 104. The position switch 103 is fixedly installed on the upper pipe clamp 101; the end of the position switch 103 presses against the lower pipe clamp 101; the indicator light 104 is fixedly installed on the upper pipe clamp 101, and the indicator light 104 is electrically connected to the position switch 103; the electric tightening part 2 includes: a rotary drum 201, a rotary screw 202, a positioning hole 2021, and a stop threaded cylinder 203. The rotary drum 201 is located above the pipe clamp 101; the rotary screw 202 is sleeved on the rotary drum 201; four openings are provided on the rotary screw 202. The positioning hole 2021; a stop threaded cylinder 203 is threadedly connected to the rotary screw 202, and the end of the stop threaded cylinder 203 is attached to the rotary cylinder 201; the electric tightening part 2 also includes: a drive gear shaft 204, an angle cylinder 205, a driven gear shaft 206, and a drive cylinder 207. The drive gear shaft 204 is fixedly installed on the rotary screw 202; the angle cylinder 205 is rotatably sleeved on the drive gear shaft 204; the angle cylinder 205 has a hollow structure; the driven gear shaft 206 is rotatably sleeved on the angle cylinder 205; the ends of the drive gear shaft 204 and the driven gear shaft 206 are respectively provided with bevel gears, and the ends of the drive gear shaft 204 and the driven gear shaft 206 are respectively provided with bevel gears. The bevel gears mesh with each other; the driven gear shaft 206 is threaded to the bottom of the drive cylinder 207; the drive cylinder 207 has a hexagonal hole; a magnet is installed inside the drive cylinder 207. The use of the laying support component 1 facilitates the support of the laid ductwork. The use of the limiting groove 1011 to clamp the angle steel flange allows for simultaneous clamping of the flanges of both upper and lower duct sections, improving the flange connection strength. Furthermore, the use of the limiting groove 1011 to clamp the flanges of both upper and lower duct sections facilitates subsequent bolt installation and fixing, preventing flange misalignment and bolt installation difficulties. Additionally, the presence switch 103 allows for easy prompting of personnel to clamp the flanges of both duct sections first. To avoid forgetting, directly use bolt connections. When ductwork docking is actually required, install the lower duct clamp 101 on the wall with bolts. At this time, place the flanges of the upper and lower ducts in the limiting groove 1011, and rotate the upper duct clamp 101 to fit the angle steel flange. Then, the upper and lower duct clamps 101 can be threaded together and tightened with the positioning bolts 102 to clamp and support the duct. At the same time, after the upper and lower duct clamps 101 are closed and clamped, the end of the position switch 103 will press against the lower duct clamp 101, and the indicator light 104 can turn off naturally. Otherwise, the indicator light 104 will remain on.

[0035] In this embodiment, the flange adapter 4 includes: a lifting slider 401 and a lower pressure plate 402. The lifting slider 401 is slidably mounted on the corner cylinder 205. The lower pressure plate 402 is fixedly mounted on the lifting slider 401 by bolts. A tension spring is connected to the top of the lifting slider 401, and the bottom end of the tension spring at the top of the lifting slider 401 is connected to the corner cylinder 205.

The magnet 404 is fixedly mounted on the bottom of the lower pressure plate 402. The magnet 404 is used to magnetically attach to the angle steel flange. The sponge block 403 is used to wipe the surface of the angle steel flange. Using the flange adapter 4 can facilitate magnetic attachment of the flange, keep the screws vertically tightened during installation, reduce the probability of misalignment, and also facilitate cleaning and wiping the surface of the angle steel flange, avoiding impurities such as sand and gravel that are not easily detected by humans, thus ensuring stable bolt installation. The structure is simple to operate and the manual operation is flexible and convenient.

[0036] In Example 2, based on Example 1, the locking component 3 includes: a locking mounting plate 301, a positioning shaft 302, and an electromagnet 303. The locking mounting plate 301 is fixedly mounted on the corner cylinder 205. The positioning shaft 302 is slidably inserted into the locking mounting plate 301, and a spring is sleeved on the positioning shaft 302. The spring on the positioning shaft 302 connects the locking mounting plate 301 and the positioning shaft 302. The electromagnet 303 is fixedly mounted on the positioning shaft 302. The positioning shaft 302 is aligned with the positioning hole 2021. The sequence limiting component 5 includes: a limiting mounting cylinder 501 and a switch shaft 502. The limiting mounting cylinder 501 is fixedly mounted on the lower pressure plate 402. The switch shaft 502 is slidably inserted into the limiting mounting cylinder 501. The end of 502 is used to align with the upper pipe clamp 101; the sequence limiting member 5 also includes: a detection switch 503, which is fixedly installed at the end of the switch shaft 502, and the detection switch 503 is used to press against the inner edge of the upper pipe clamp 101 or the screw that has been installed; the detection switch 503 is electrically connected to the electromagnet 303; the sequence limiting member 5 also includes: an adapter spring 5021, which is sleeved inside the limiting installation cylinder 501, and the adapter spring 5021 is connected between the limiting installation cylinder 501 and the switch shaft 502. The use of the sequence limiting member 5 can facilitate the workers to install screws in sequence during actual installation, avoiding the difficulty of accurate observation in narrow spaces. The placement of screws can lead to omissions or improper installation of a row of screws, resulting in inconsistent stress on the flange connection. This structure addresses this by installing a detection switch 503 at the end of the switch shaft 502. The locking element 3 is only released after a bolt is detected on the front side. Combined with the laying support element 1, this assists in pressing the detection switch 503 at the initial end, ensuring proper installation of the first bolt. Operation is simple and unaffected by confined spaces. The locking element 3 can also lock the rotating screw 202, facilitating standardized operation and further improving the standardization of flange connections. The locking indicator is also intuitive; when tightening screws, the end of the switch shaft 502 needs to be... The detection switch 503 presses against the top of the already installed screw. The limited distance between the detection switch 503 and the drive cylinder 207 restricts the screw installation area, preventing any screws from being missed. Simultaneously, the elasticity of the adapter spring 5021 allows the switch shaft 502 to slide elastically, maintaining a certain detection range for the detection switch 503. This allows the detection switch 503 to press against the pipe clamp 101 above when installing the first screw, de-energizing the electromagnet 303. Combined with the spring pressure on the positioning shaft 302, the positioning shaft 302 will not insert into the positioning hole 2021. After the first screw is installed, subsequent screw installations can be performed by pressing against the already installed screw using the detection switch 503.

[0037] The working principle of this embodiment is as follows: First, when ductwork connection is required, the lower duct clamp 101 is bolted to the wall. Then, the flanges of the upper and lower ducts are placed in the limiting groove 1011, and the upper duct clamp 101 is rotated to fit against the angle steel flange. Afterwards, the upper and lower duct clamps 101 are threaded together and tightened using the positioning bolts 102 to clamp and support the ductwork. Simultaneously, after the upper and lower duct clamps 101 are closed and clamped, the end of the position switch 103 will press against the lower duct clamp 101, activating the indicator light. 104 can turn off naturally; otherwise, indicator light 104 will remain lit. The rotary screw 202 can be clamped using the chuck at the output end of the drill. Holding the rotary drum 201, insert the screw to be installed into the drive cylinder 207, using the magnet inside the drive cylinder 207 to magnetically attract the screw. While holding the rotary drum 201, slide the magnet 404 onto the surface of the angle steel flange. This helps to indicate the vertical position of the drive cylinder 207, facilitating subsequent vertical screwing into the angle steel flange. The movement of the sponge block 403 also serves to brush the surface of the angle steel flange. The screw... Align the connection holes of the angle steel flange. Threads can be pre-cut on the lower angle steel flange or nuts can be welded to the bottom. As the electric drill drives the rotary screw 202 to rotate, it drives the drive gear shaft 204 to mesh with the driven gear shaft 206, which in turn drives the drive cylinder 207 to drive the screw for installation and tightening. This method is more suitable for installation in confined spaces. When installing the first screw, the detection switch 503 can be pressed against the upper pipe clamp 101 to de-energize the electromagnet 303. Combined with the spring pressure on the positioning shaft 302, the positioning shaft 302 will not... Insert the positioning hole 2021. Conversely, once the detection switch 503 is not pressed, the electromagnet 303 will be electromagnetically attracted to the rotary screw 202. When the rotary screw 202 rotates, the positioning shaft 302 will be inserted into the positioning hole 2021 and locked in position. After the last bolt on the wall side is installed, you can switch to the other side and install the screws on the side near the pipe clamp 101 above. During installation, the already installed screws can be used to press the detection switch 503 to control the electromagnet 303 to cut off the power, ensuring that the screw rotation drive can be performed normally.
