Description

Technical Field

[0001] The utility model belongs to the technical field of road construction, and in particular relates to a HVAC pipeline construction device. Background Art

[0002] HVAC pipelines include purification device ducts, central air conditioning ventilation ducts, industrial air supply and exhaust ventilation ducts, environmental protection system suction and exhaust ducts, mining gas extraction pipes, etc. In actual construction applications, due to the long pipeline laying path, one pipeline cannot meet the construction requirements, so multiple pipelines need to be spliced ​​to form a pipeline or pipeline network. How to complete the docking of pipelines during manufacturing, processing and construction is a technical problem. Most of the existing ones use cranes and then manually move and align them, which undoubtedly increases the labor intensity of workers and reduces the accuracy of docking. If there is a deviation in pipeline docking, it is easy to cause pipeline leakage, which is not conducive to the construction progress, and will also increase the difficulty of subsequent maintenance and overhaul. Therefore, how to achieve accurate docking of pipelines is a problem to be solved.

It can only be installed through an open-shaped inclined platform. The inclined platform has an inclined bottom surface. The bottom surface and the baffle are used to place the pipes. The pipes are arranged in this way and need to enter the inclined platform for rolling.

[0045] The mounting platform 3 is connected to the top of the support seat 2, and the two relatively arranged clamping devices 4 of the mounting platform 3 can drive the clamping devices 4 to adjust their height vertically through the support seat 2 at the bottom to adapt to the installation of pipelines at different heights; the fixing seat 41 in the clamping device 4 has a positioning device 42, and the positioning component 421 of the positioning device 42 is connected to the bottom of the fixing seat 41 to support the bottom of the pipeline, and the clamping components 422 of the positioning device 42 are arranged on both sides of the fixing seat 41 to clamp the two sides of the radial direction of the pipeline, thereby forming a three-point fixation of the pipeline, avoiding the traditional two-point clamping that can only be achieved on the side of the pipeline, ensuring that the full point position of the pipeline will not be displaced in the construction device, thereby further improving the positioning accuracy and improving work efficiency.

[0046] As a preferred embodiment, the fixing seat 41 includes a first clamping plate 411 and a second clamping plate 412 slidably connected to one side of the first clamping plate 411; a frame structure for accommodating the pipeline is formed between the first clamping plate 411 and the second clamping plate 412; the clamping assembly 422 is connected to the opposite sides of the first clamping plate 411 and the second clamping plate 412; an adjusting device 5 is connected between the first clamping plate 411 and the second clamping plate 412, which is used to adjust the distance between the second clamping plate 412 and the first clamping plate 411, so as to clamp the pipeline on both sides along the radial direction of the pipeline.
