Description
Technical Field
[0001] The utility model relates to the technical field of chimneys, in particular to a detachable assembly tool for a small-pitch sleeve-type chimney. Background Art
[0002] A chimney is a structure that provides ventilation for hot flue gases or smoke from boilers, furnaces, and fireplaces. Chimneys are typically vertical structures to ensure a smooth flow of gases. The space within the chimney is called a flue. With the continuous advancement of industrial technology, and to improve the convenience of chimney construction, free-standing steel chimneys are mostly used instead of traditional concrete chimneys. Free-standing sleeve chimneys are composed of an inner and outer tube. The outer tube is responsible for self-supporting function, so a series of technical indicators such as strength and lifespan must be considered. The inner tube is responsible for exhausting smoke, so it has higher corrosion protection requirements. Because the inner tube is attached to the outer tube, the requirements for corrosion protection and weight reduction are also relatively strict. Therefore, the inner tube is generally made of thin, corrosion-resistant materials.
[0003] Existing sleeve-type chimneys are typically manufactured, transported, and installed in sections. During factory assembly, each chimney section requires the inner tube to be inserted into the outer tube, followed by the fabrication of accessories such as openings. Therefore, when the spacing between the inner and outer tubes is very small, it is impossible to install assembly features such as sliders on the inner tube, making it difficult to install the inner tube into the outer tube. Direct installation will cause hard friction between the steel and damage the tube paint and flanges. Therefore, we have developed a removable assembly tool for sleeve-type chimneys with small spacing. Utility Model Content

[0019] 1. When using the detachable assembly tool for the small-pitch sleeve chimney, it is moved to the specified position through two rollers, and then the first threaded hole on the L-shaped plate is connected to the external thread of the inner tube flange to fix the inner tube and the L-shaped plate. Then, one of the rollers is fixed to fix the mounting frame to the ground. The two mounting frames are respectively fixed to the two ends of the electric push rod. When the electric push rod works, the mounting frame on one side of the L-shaped plate moves through the roller on the side, and the inner tube fixed to the L-shaped plate by bolts moves toward the outer tube.

A rotating cylinder is provided on the inner wall of the mounting groove through a fixed rod sleeve. The surface of the rotating cylinder is smooth, and the outer wall of the rotating cylinder is higher than the upper surface of the mounting plate, so that the lower side of the inner cylinder can be slidably connected to the outer wall of the rotating cylinder, so that the inner cylinder can be more stable when entering the outer cylinder. When the roller on this side is fixed, the electric push rod is used to pull the other side of the electric push rod on this side. While the inner cylinder continues to enter the outer cylinder, the two mounting frames are close to each other, which is convenient to operate, improves stability, and saves labor and cost.
