Automatic tube penetrating equipment for tube type heat exchangers

Abstract

The invention discloses automatic tube penetrating equipment for tube type heat exchangers. The automatic tube penetrating equipment comprises a displacement roller carrier for placing and driving theheat exchangers to rotate, wherein two gantry type frames which are symmetrically distributed front and back are arranged in front of heat exchanger front end tube plates, two horizontal movement andvertical movement driving mechanisms are arranged on the gantry type frames, and lifting columns are arranged on the driving mechanisms; a tube grabbing and penetrating driving device is mounted at the lower ends of two lifting columns; and automatic tube feeding devices are installed at the left side and the right side between the two gantry type frames, the tube grabbing and penetrating drivingdevices grab heat exchange tubes and conveys the heat exchange tubes forwards, and the horizontal movement and vertical movement driving mechanisms drive the tube grabbing and penetrating driving devices to reach any designated hole positions of the heat exchanger front end tube plates, so that the grabbed heat exchange tubes are concentric with the hole positions of the heat exchanger front endtube plates. By the automatic tube penetrating equipment, automatic tube feeding, automatic tube turning, automatic tube grabbing, automatic tube plate hole searching and automatic tube pushing can beachieved, and automation of the tube penetrating process is achieved.

Description

technical field [0001] The invention belongs to the technical field of manufacturing tube-and-tube heat exchangers, and in particular relates to automatic tube-threading equipment for tube-and-tube heat exchangers. Background technique [0002] Tube and tube heat exchangers are commonly used equipment in petroleum, chemical, nuclear power, special boiler systems, light industry, food and other industries. The shell and tube heat exchanger is mainly composed of a shell, a tube bundle, a tube plate, a baffle and a head. Both ends of the tube bundle are fixed on the tube plate, and the middle passes through small holes on multiple baffle plates. Because the tube is slender, the number of tubes is large, and the number of baffles is large, the resistance when the tube penetrates is large. It takes multiple operators to lift a tube and align the end of the tube with the hole of the tube plate, and then push the tube manually , need to consume a lot of physical strength, the lab...

AI Technical Summary

Problems solved by technology

Because the tube is slender, the number of tubes is large, and the number of baffles is large, the resistance when the tube penetrates is large. It takes multiple operators to lift a tube and align the end of the tube with the hole of the tube plate, and then push the tube manually , need to consume a lot of physical strength, the labor intensity of the operator is high, and the production efficiency is low, which seriously restricts the manufacturing speed of the heat exchanger. In the manufacture of the fixed tube-sheet shell-and-tube heat exchanger, the penetration of the tube bundle affects the production efficiency an important process

[0003] The existing technology generally uses some simple mechanical devices to assist pipe penetration, which can reduce the labor intensity of manual pipe penetration to a certain extent, but it still needs to manually adjust the mechanical devices to align them with the holes on the tube plate, and then through the reciprocating feeding method Or roller force feeding method, the production efficiency is low, especially not suitable for large-diameter, long-length large-scale tube-and-tube heat exchangers
