Limiting and guiding device

Abstract

The invention belongs to the technical field of pipeline connecting structures, and particularly relates to a limiting and guiding device. The limiting and guiding device comprises a bottom plate, vertical roller guiding supports, vertical rollers, transverse roller guiding supports, transverse rollers and pipeline connecting parts. The number of the vertical roller guiding supports is two, the two vertical roller guiding supports are mounted on the bottom plate in relatively parallel, and upper limiting holes and lower limiting holes are formed in the vertical roller guiding supports. The vertical rollers are arranged in the upper limiting holes and the lower limiting holes of the vertical roller guiding supports and can freely roll in the limiting holes of the vertical roller guiding supports. The transverse roller guiding supports are fixed to the position, between the two vertical roller guiding supports, of the bottom pate, and limiting grooves are arranged on the transverse roller guiding supports. The transverse rollers are arranged in the limiting grooves of the transverse roller guiding supports and can freely roll in the limiting grooves. The pipeline connecting parts arein rolling connection with the vertical rollers and the transverse rollers. By means of the limiting and guiding device, the vertical rollers and the transverse rollers are arranged on the bottom plate, sliding friction is converted into rolling friction, friction resistance is effectively reduced, secondary stress release of pipelines is facilitated, and the work stability and reliability of thelimiting and guiding device are improved.

Description

technical field [0001] The application belongs to the technical field of pipeline connection structures, and in particular relates to a position-limiting guide device. Background technique [0002] With the rapid development of aero-engine technology, the high-temperature pipe network of the test equipment that is compatible with it is becoming more and more complex, and higher requirements are put forward for the pipe limit and guide devices supporting the high-temperature pipe network. However, the current limit involved in the national standard The guiding device is far from meeting the requirements of use. [0003] like figure 1 As shown, the existing limit guide device relies on the fixed adjustable baffles on both sides to realize the lateral limit, and the axial displacement is realized by sliding the pipe connector on the PVC plate, and the vertical limit depends on the upper edge of the adjustable baffle and the The outer edge of the bottom plate of the pipe conne...

AI Technical Summary

Problems solved by technology

However, the existing limited guide device also has the following disadvantages: the movement between the pipe connector and the adjustable baffles on both sides and the PVC board is all sliding friction, and the friction resistance is relatively large, and the large friction resistance may cause the pipe to Damage to the weak parts of the network system may even cause more serious consequences; the adjustable baffles on both sides are directly welded and fixed on the bottom plate. The effect is not good, and because the distance between the adjustable baffles on both sides is not adjustable, the installation of the pipe connectors is often inconvenient, resulting in an increase in installation costs and a lag in project progress
