AI Technical Summary
In the chemical industry, when replacing pipe bundles with pipe heat exchangers, it is difficult to remove the old pipe bundles, the dismantling workload is large, the traditional method is inefficient and there is a risk of damage.
Design a tool that includes a clamp frame, a jack and a locking slider. The clamp frame is made of a C-shaped frame made of 10mm thick steel plate. The piston rod of the jack is aligned with the opening of the clamp frame and contacts the expansion joint bundle through the top cone of the jack. , shake the jack to remove the tube bundle.
It realizes the safe and efficient removal of small-diameter pipes with expansion and connection, reduces manual operations and improves labor efficiency. A single person can remove 150 pipes a day, which is 3 times higher than the traditional method.

Abstract
Description
Technical Field
[0001] The utility model relates to a tool for quickly dismantling expansion-jointed small-diameter pipelines. Background Art
[0002] At present, tubular heat exchangers are widely used in the chemical industry. Tubular heat exchangers have the characteristics of many tube bundles, large heat exchange area and high investment cost. However, in the process of replacing the tube bundle, there are problems such as difficulty in removing the old tube bundle and large workload of removal. In the traditional process of removing the tube bundle, it mainly relies on the method of manual hammering, which is inefficient and cannot meet the maintenance needs. Taking the maintenance of the 1# primary cooler of the coking chemical industry as an example, the lower section of the 1# primary cooler contains a total of 14 heads, each of which contains 200 expanded DN32 heat exchange tubes, with a total of 2,800 heat exchange tubes. In the case of manual hammering, each group of 2 people can remove a maximum of 100 heat exchange tubes per day, and there is also a risk of injury. Summary of the invention
[0003] In order to safely and efficiently remove the heat exchange tubes of the primary cooler, a tool for quickly removing the expanded small-diameter pipes was developed. The tool is easy to operate, requires less investment, and is highly efficient.
[0004] The purpose of the utility model is achieved as follows: a tool for quickly removing expansion joints of small-diameter pipes, comprising a card frame, the card frame is a C-shaped frame made of 10mm thick steel plate, the opening of the card frame is respectively provided with corresponding bayonet openings in the two side walls, a guide rail is provided on the card frame body on the other side of the card frame opposite to the opening, a locking slider is provided on the guide rail, a jack is provided on the locking slider, and the free end of the piston rod of the jack faces the opening of the card frame.
[0005] When in use, clamp the clamping frame on the edge of the head of the primary cooler body, place the jack in the clamping frame, put the top cone of the jack in the pipe bundle to be jacked, shake the jack to hold the top cone, and then the expanded pipe bundle can be safely and efficiently removed. With the utility model, the operation that required the cooperation of two people in the early stage can now be completed by one person, and the operation method of hammering is improved, the operation process is safer, and the efficiency is increased from 2 people to 100 per day to 1 person to 150 per day, and the labor efficiency is increased by 3 times. BRIEF DESCRIPTION OF THE DRAWINGS
[0006] Figure 1 It is a schematic diagram of the main structure of the utility model. DETAILED DESCRIPTION
[0007] A tool for quickly removing expansion joints of small diameter pipes, such as Figure 1As shown, it includes a card frame, which is a C-shaped frame made of 10 mm thick steel plate. The card frame has corresponding openings 4 arranged in the two side walls thereof. A guide rail 8 is arranged on the card frame body on the other side of the card frame opposite to the opening. A locking slider 7 is arranged on the guide rail. A jack 6 is arranged on the locking slider 7. The free end of the piston rod 5 of the jack 6 faces the opening of the card frame.
[0008] When in use, clamp the clamping frame clamping mouth 4 on the edge of the head 1 of the primary cooler body, place the jack 6 in the clamping frame, put the top cone of the jack into the tube bundle to be jacked, shake the jack to support the top cone, and then the expanded tube bundle 3 on the tube sheet 2 can be safely and efficiently removed.
