Problems solved by technology

[0004] However, the above-mentioned device for assembling the double-layer thermal insulation spiral air duct and most of the existing devices for assembling the double-layer thermal insulation spiral air duct, when assembling, the outer spiral air duct is placed on the large-diameter spiral air duct support device, Put one end of the inner spiral air duct into the outer spiral air duct, and push the inner spiral air duct to the outer spiral air duct through the propulsion device. During the pushing process, because the inner spiral air duct is in the overhead state, the inner spiral air duct The self-weight of the inner helical duct will cause the movement of the inner helical duct to shift downwards. The axis of the inner helical duct and the axis of the outer helical duct cannot be collinear, which brings certain resistance to the installation of the inner helical duct. It even caused the inner spiral air duct to fail to slide in the outer spiral air duct, which greatly affected the progress of the double-layer spiral air duct assembly

Embodiment 1

[0036] Embodiment 1: A kind of assembly equipment of double-layer spiral air duct, such as Figure 1 to Figure 3 As shown, it includes a frame 3, the frame 3 is a frame body in the shape of a cuboid, and the frame 3 is provided with a placement part 4 for placing and fixing the outer spiral air duct 1, and the placement part 4 includes a The placement frame 402 and the fixed ring 401 that are attached to the outer wall, the placement frame 402 is fixedly installed on the frame 3, the upper end of the placement frame 402 is recessed from top to bottom to form a placement groove 7, the inner wall of the placement groove 7 is connected to the outer spiral air duct 1 The outer pipe wall of the pipe is attached to prevent the outer spiral air pipe 1 from rolling in the axial direction. The shape of the fixed ring 401 is a semi-annular body, and one end of the semi-annular body is rotationally connected with the upper end surface of the placement frame 402. In this implementation In...

Embodiment 2

[0043] Embodiment 2: A kind of assembly equipment of double-layer spiral air duct, such as Image 6 As shown, the difference from Embodiment 1 is that on the basis of Embodiment 1, an elastic sleeve 28 is sleeved on the fixing ring 401, and an elastic gasket 27 is provided on the inner wall of the placement groove 7, and the elastic sleeve 28 and the elastic The gaskets 27 are made of elastic rubber material and have a certain degree of elasticity. Place the outer spiral air duct 1 in the fixing ring 401 and the placement groove 7. By setting the elastic sleeve 28 and the elastic gasket 27, the pressing block 601 is avoided. When the pressure is too high during the pressing down process, the fixed ring 401 may crush the outer spiral air duct 1, and the elastic sleeve 28 and the elastic gasket 27 play a role in buffering the pressure, which greatly improves the product quality of the outer spiral air duct 1 during the assembly process .

Abstract

The invention discloses assembly equipment for a double-layer spiral duct. The assembly equipment is characterized in that a rack is included, the rack is provided with a containing part used for containing and fixing an outer spiral duct body and a pushing device used for pushing an inner spiral duct body into the outer spiral duct body, the rack is provided with at least one pair of supporting assemblies which axially slide along the outer spiral duct body and a first driving part used for driving the supporting assemblies to relatively slide to support the inner spiral duct body, and the two supporting assemblies play a supporting role on the inner spiral duct body, so that the axis of the inner spiral duct body and the axis of the outer spiral duct body always keep collinear. The two supporting assemblies can slide back to back to be away from the inner spiral duct body, the condition that the supporting assemblies cause interference to penetration of the inner spiral duct body is avoided, therefore, the inner spiral duct body is smoothly pushed into the outer spiral duct body, and assembly is smoother and more efficient.

Description

technical field [0001] The invention relates to the field of air duct processing and production, in particular to an assembly device for a double-layer spiral air duct. Background technique [0002] The spiral air duct is a thin-walled tube made of a spiral seam with a metal strip. It is round, has no welding, no air leakage, and no water leakage. It is mostly used for air supply and bulk material transportation. In daily life, the spiral air duct is the most widely used. The most widely used is the central air-conditioning pipeline. This kind of pipeline generally passes through the spiral outer tube and the spiral inner tube that are nested in each other. At that time, the outer tube wall of the inner tube is artificially wound and pasted with thermal insulation cotton, and then the spiral inner tube is installed. To the inner pipe wall of the spiral outer pipe, a double-layer thermal insulation spiral air duct is formed, which can play a better role in heat preservation i...
