Description

Technical Field

[0001] This invention relates to the field of tube bundle equipment, and more specifically to a traction device for threading tubes through tube sheets. Background Technology

[0002] Currently, there are many types of equipment in the chemical industry that contain tube bundles, and without exception, the tube bundle is one of the most critical components of these devices.

[0003] However, currently, the main method for inserting tubes into chemical equipment is to manually insert individual tubes one by one. First, the individual tubes are inserted sequentially through the tube sheet with pre-drilled holes, and then welding is performed.

[0004] For tube sheets with slightly larger diameters, the distance between tube sheets is also relatively long, usually 1m to 3m. During the manual splicing process, because the tube bundles are generally long, several people are often needed to work together. The splicing at the front end is relatively easy. However, once a slightly larger number of tube sheets are spliced, it is often necessary to arrange personnel on the other side of the tube sheet to assist in preventing the tube bundles from extending too far and causing bending damage, which would lead to production quality problems. Furthermore, due to the continuous use of manual splicing, the labor intensity of workers is high and the work efficiency is low. Summary of the Invention

[0005] The main objective of this invention is to provide a traction device for tube passing through tube sheets, which can conveniently and quickly pull tube bundles through tube sheets without the need for worker assistance, thus improving work efficiency.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A traction device for tube-to-tube sheet installation includes a tube sheet fixing seat, wherein the tube sheet fixing seat is provided with a tube sheet mounting groove along the length direction;

[0008] The pipeline traction device is provided with a sliding block B, and a traction rod is fixedly connected to the sliding block B and facing the plate fixing seat. The end of the traction rod is provided with an air expansion shaft for insertion into the tube bundle.

[0009] The plate fixing seat and the pipeline traction device are sequentially arranged along the production line.

[0010] Furthermore, the pipeline traction device includes a base B and a traction frame A. A guide rail B is provided on the upper surface of the base B along the length direction. The traction frame A is movably connected to the guide rail B. Two sets of screw modules C are vertically arranged inside the traction frame A. A screw module D is fixedly connected between the guide blocks C of the two sets of screw modules C. The sliding block B is fixedly connected to the guide block D of the screw module D.

[0011] Furthermore, the traction device also includes a traction frame B, in which two sets of lead screw modules E are vertically arranged. A lead screw module F is fixedly connected between the guide blocks E of the two sets of lead screw modules E. A support block is fixedly connected to the guide block F of the lead screw module F, and the support block is provided with a guide hole for the traction rod to pass through.

[0012] Furthermore, the guide rail B has a wedge-shaped structure, and the bottom of the traction frame A and traction frame B are provided with matching sliding grooves. The lower parts of the traction frame A and traction frame B are movably connected to the base B through two lead screw modules respectively.

[0013] Furthermore, the tube sheet mounting groove is provided with multiple sets of limiting pins.

[0014] Furthermore, the free end of the traction rod is rounded, and the air shaft is a keyed air shaft.

[0015] Furthermore, the air key of the air shaft is made of rubber.

[0016] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0017] I. This patent provides a traction device at the rear end of the plate fixing seat, using a traction rod whose position can be adjusted arbitrarily, and an air shaft at the front end of the traction rod. The air shaft is inserted into the tube bundle, and after the air shaft is activated, the traction device is used to pull the tube bundle, which is convenient, fast, and improves production efficiency.

[0018] Second, by setting multiple lead screw modules on the traction frame A, the sliding block B can be adjusted in position as needed, which meets the usage requirements.

[0019] Third, by setting up a traction frame B as a support for the traction rod, it is possible to prevent the traction rod from being too long, causing the head to bend and making traction impossible.

[0020] Fourth, the guide rail B is set as a wedge structure to prevent the positions of the traction frame A and traction frame B from changing. At the same time, two sets of screw modules are set to control the traction frame A and traction frame B respectively, so that the position between the two can be changed as needed.

[0021] 5. By setting limit pins on the tube sheet mounting groove, the tube sheet can be effectively fixed. Attached Figure Description

[0026] like Figures 1-4 As shown, a traction device for tube sheet insertion includes a tube sheet fixing seat 30, wherein the tube sheet fixing seat 30 is provided with a tube sheet mounting groove 301 along the length direction;

[0027] The pipe traction device 40 is provided with a sliding block B401, and a traction rod 4011 is fixedly connected to the sliding block B401 and is provided with a traction rod 4011 facing the plate fixing seat 30. The end of the traction rod 4011 is provided with an air expansion shaft 4012 for inserting into the pipe bundle.

[0028] The plate fixing seat 30 and the pipeline traction device 40 are arranged sequentially along the production line.

[0029] Furthermore, the pipeline traction device 40 includes a base B402 and a traction frame A403. A guide rail B4021 is provided on the upper surface of the base B402 along the length direction. The traction frame A403 is movably connected to the guide rail B4021. Two sets of lead screw modules C4031 are vertically arranged inside the traction frame A403. A lead screw module D4032 is fixedly connected between the guide blocks C of the two sets of lead screw modules C4031. The sliding block B401 is fixedly connected to the guide block D of the lead screw module D4032.

[0030] Furthermore, the traction device 40 also includes a traction frame B404, in which two sets of lead screw modules E4041 are vertically arranged. A lead screw module F4042 is fixedly connected between the guide blocks E of the two sets of lead screw modules E4041. A support block 4043 is fixedly connected to the guide block F of the lead screw module F4042. The support block 4043 is provided with a guide hole 40431 for the traction rod 4011 to pass through.

[0031] Furthermore, the guide rail B4021 has a wedge-shaped structure, and the bottom of the traction frame A403 and traction frame B404 are provided with matching sliding grooves. The lower parts of the traction frame A403 and traction frame B404 are movably connected to the base B402 through two lead screw modules respectively.

[0032] Furthermore, in order to ensure that the tube sheet is stable and does not shift after installation, the tube sheet mounting groove 301 is provided with multiple sets of limiting pins 3011.

[0033] Furthermore, to facilitate the insertion of the traction rod 4011 into the tube bundle, the free end of the traction rod 4011 is rounded, and the air shaft 4012 is a keyed air shaft.

[0034] Furthermore, in order to ensure that the air shaft can provide more stable traction, the air shaft key is made of rubber.

[0035] Specifically, in use, the tube sheet is first hoisted and placed on the plate fixing seat 30 according to the settings. After all the tube sheet positions are adjusted, they are fixed with limit pins 3011. The lead screw module F4042 is set on one side as the origin, and a coordinate system is set. The holes on the tube sheet are marked by a digital coordinate system, such as (xi,yi,zi), where i is a real number (or a digital coordinate system can be not established, and the position of the traction rod can be adjusted manually according to the actual situation). The worker inserts the tube bundle into the tube sheet from one end of the plate fixing seat 30. The position of the traction rod 4011 is adjusted by the servo motor to align with the tube bundle to be inserted. The air shaft 4012 is inserted into the tube bundle. When the air shaft expands, it clamps with the inner wall of the tube bundle. The open part of the air shaft is made of rubber material, which not only serves as a clamping function but also prevents the tube from being squeezed and deformed. After clamping, the traction rod 4011 is controlled to return to its original position. Due to friction, the tube bundle moves with the movement to be inserted. When it moves to the appropriate position, the air shaft is released, thus completing one tube insertion. By repeating this process, the tube bundle can be threaded through (the air shaft end is equipped with an air hole connected to the air source, which is not shown in this figure; the lead screw module adopts a CNC servo motor, and the device is automatically operated by programming, which replaces the traditional manual tube threading and greatly reduces human intervention. The specific programming method is existing technology and will not be described in detail in this patent).
