Description

TECHNICAL FIELD

[0001] The present application relates to a large-diameter cylinder segment split tool, belonging to the technical field of large-diameter cylinder longitudinal split tool. BACKGROUND

[0002] Due to the characteristics of the cylindrical structure and large radial size of the large-diameter cylinder, direct transportation and transportation are difficult, and there are great safety hazards during transportation. In order to avoid these problems, existing manufacturers usually split the cylinder longitudinally into multiple pieces in the factory, then stack and transport them, and finally assemble them into a complete cylinder at the installation site for use.

[0003] The existing longitudinal split tool of the large-diameter cylinder is shown in the Chinese utility model patent "Authorization announcement number: CN219444830U; authorization announcement date: August 1, 2023; name: Tower cylinder split split tool", which adopts a structure including a cross beam, a vertical support beam arranged on the cross beam, and a lower connecting plate. The top of the vertical support beam is provided with an upper connecting plate, and the lower connecting plate is directly fixed on the lower cross beam. Rollers are arranged on both sides of the lower side of the cylinder. When in use, the rollers are used to realize the overturning of the large-diameter cylinder, and the upper and lower connecting plates are used to fix and connect the large-diameter cylinder. The split tool has the following disadvantages: 1. The vertical support beam is vertically arranged, and when supporting the end of the large-diameter cylinder, the large-diameter cylinder will be obliquely extruded, causing the vertical support to have an oblique folding tendency. Long-term use can cause the vertical support beam to bend; 2. The height of the upper connecting plate at the top of the vertical support beam is high. When fixing and disassembling the upper connecting plate and the flange at the end of the large-diameter cylinder, workers need to climb to a high position to operate, which is low in efficiency and dangerous; 3. When cutting the large-diameter cylinder longitudinally, the large-diameter cylinder needs to be overturned. However, when cutting the second and subsequent longitudinal lines, in order to ensure that the large-diameter cylinder does not deform as a whole, end connecting plates need to be arranged on the outside of the flanges at both ends of the cut longitudinal line. The rotation of the large-diameter cylinder will cause the end connecting plates to interfere with the upper and lower connecting plates, so the end connecting plates need to be rotated by lifting the large-diameter cylinder or moving the end tool longitudinally to provide space for the rotation of the end connecting plates. The operation is complicated, and the labor intensity of workers is large. SUMMARY

[0039] The connecting device 4 includes a bottom plate seat 41 and a plug-in mechanism arranged on the upper surface of the bottom plate seat 41. The bottom plate seat 41 of the connecting device 4 at the top of the side support 33 is a V-shaped plate or an arc-shaped plate with an upward concave surface, and the bottom plate seat 41 of the connecting device 4 at the top of the bottom support 32 is a straight plate arranged transversely or a V-shaped plate or an arc-shaped plate with an upward concave surface.

[0040] The use principle of the embodiment one is:

[0041] First, the large-diameter cylinder section 1 is hoisted and placed on the roller frame 2, and the roller frame 2 is started to rotate the large-diameter cylinder section 1, so that the corresponding connecting through holes 51 on the end flange 5 are respectively aligned with the latches 45 of the connecting device 4 of the bottom support 32 and the side support 33;

[0042] Then, the push cylinder 46 is started to extend, and the telescopic rod 462 of the push cylinder 46 first synchronously pushes the support sliding block 44 and the latch 45 forward, and in this process, the spring 47 is compressed. When the front side of the support sliding block 44 abuts against the end flange 5, more than half of the support sliding block 44 still stays in the sliding block through cavity 43, and the support sliding block 44 stops advancing. With the continuous forward pushing of the push cylinder 46, the spring 47 is further compressed, and the latch 45 continues to advance until the connection through hole 51 on the end flange 5 is completely connected.

[0043] The longitudinal markings on the large-diameter cylinder section between the two bottom supports 32 are cut, and after the cutting is completed, a longitudinal flange 11 is installed on the inner side of the longitudinal cut, a bolt is installed on the longitudinal flange 11, and the longitudinal cut is connected. Then, the flange connecting plate 6 is used to connect the cut end flange 5.

[0044] The connection between the connecting device 4 and the end flange 5 is disconnected (the telescopic rod 462 of the push cylinder 46 is retracted, and the support sliding block 44 and the latch 45 inside it are retracted as a whole to the sliding block through cavity 43 with the retraction of the telescopic rod 462 and the back pulling force of the spring 47), the roller frame 2 rotates the large-diameter cylinder section 1 to move another longitudinal marking between the two bottom supports 32, and the foregoing operation is repeated until the three longitudinal markings on the side wall of the large-diameter cylinder section 1 are completely cut and connected.

[0045] Finally, the first hoisted form is used to first separate the top piece, then separate the piece on the side with the counterweight plate 34, and finally separate the third piece. The separation operation of the large-diameter cylinder section 1 is completed.

[0048] The principle of use of embodiment two differs from that of embodiment one in that, when the connection of the disconnection device 4 and the end flange 5 is released, the retraction of the support slider 44 and of the pin 45 inside it into the slider through cavity 43 is achieved by means of the telescopic sleeve group, and not by means of the pulling force of the stretched spring 47.
