Description

Technical Field

[0001] The utility model belongs to the technical field of steel - sleeved steel production equipment, and particularly relates to an external compensation fixed end - seal for the steel - sleeved steel well wall Background Technique

[0002] Steel - sleeved steel is one of the most common steel - made material pipelines at the present stage. During the production process of steel - sleeved steel pipelines, multiple processes are required, including welding technology. When welding steel - sleeved steel, compensation for the welding position is also needed to ensure the integrity of the performance of the steel - sleeved steel after welding. Especially for the weld compensation at the port of the steel - sleeved steel well wall, the weld compensation at this place needs to use an end - seal.

[0003] The existing end - seal for weld compensation at the port of the steel - sleeved steel well wall is mainly a hollow tubular object. When in use, it can be directly inserted into the port of the steel - sleeved steel well wall.

[0004] The above - mentioned end - seal for weld compensation at the port of the steel - sleeved steel well wall has the problems that when sealing the port of the steel - sleeved steel well wall, due to the non - adjustable caliber, it can only be applicable to the steel - sleeved steel that matches it, and the application range is narrow; and when in use, it also needs to use lifting equipment or a fixed mounting rack. At the same time, because the steel - sleeved steel itself is extremely heavy, it is extremely difficult to insert it onto the end - seal, which is not conducive to operation. Therefore, we provide an external compensation fixed end - seal for the steel - sleeved steel well wall to solve the problems that appear above. Content of the Utility Model

[0005] The purpose of the utility model is to provide an external compensation fixed end - seal for the steel - sleeved steel well wall. By using a sliding component, the end - seal cylinder placed on it can be pushed closer to or farther away from the notch of the steel - sleeved steel to complete the assembly or disassembly effect. Through the cooperation of the support component and the fastening component, the connection tightness between the steel - sleeved steel and the end - seal cylinder is further improved, solving the problems that appear in the existing end - seal for weld compensation at the port of the steel - sleeved steel well wall.

[0006] To solve the above - mentioned technical problems, the utility model is realized through the following technical solutions:

Specific embodiment 1

[0030] Please refer to Figures 1 - 3 , the present invention is a steel - sleeve - steel well - wall outer compensation fixed end seal, including a machine body 1 and a sliding assembly 3 installed thereon. Through the sliding assembly 3, not only can the end - sealing cylinder 4 be carried, but also the end - sealing cylinder 4 can be driven to move back and forth in the slide groove 101. When the end - sealing cylinder 4 moves, the distance between the end - sealing cylinder 4 and the steel sleeve - steel can be adjusted, and it can also be separated from the steel sleeve - steel.

[0031] Specifically, a slide groove 101 is opened on the machine table 1, and the machine table 1 is slidably connected to the sliding assembly 3 through the slide groove 101. At the same time, cover plates 2 are provided on both the left and right sides of the machine table 1. Among them, the sliding assembly 3 includes a bearing plate 301 and a slide plate 302 welded to its bottom. The card box 303 in the upper side wall of the bearing plate 301 is clamped with the card plate 403 at the bottom of the end - sealing cylinder 4. Hydraulic rods 1 304 are installed on both sides of the slide plate 302, and an end - sealing sleeve 5 is fixedly installed on the outer wall of the end - sealing cylinder 4.

[0032] Furthermore, a box rod 303a is inserted through the card box 303, and the card box 303 is connected to the card plate 403 through the box rod 303a. At the same time, side grooves 401 are opened at both axial ends of the end - sealing cylinder 4, inner grooves 402 are opened at the bottoms of the side grooves 401, and inner holes 402a for installing the hydraulic rod 2 601 or the spring tube 604 are opened on the bottom side walls of the inner grooves 402. One end of the hydraulic rod 1 304 is connected to the slide plate 302 through a rod sleeve 304a, and the other end of the hydraulic rod 1 304 is connected to the cover plate 2 through a fixed bracket 304b.

[0033] The operation process of this embodiment is as follows: Move the machine table 1 to the side of the steel sleeve, align the end-sealing cylinder 4 with the steel sleeve, then start the sliding assembly 3. The hydraulic rod 304 in the sliding assembly 3 operates, driving the slide plate 302 on its shaft end to slide in the chute 101. When it slides, the end-sealing cylinder 4 clamped and placed on the bearing plate 301 gradually approaches the port of the steel sleeve until the port of the end-sealing sleeve 5 contacts the notch of the steel sleeve and stops. Specific Embodiment 2

[0035] Please refer to Figures 4 - 5 , on the basis of Specific Embodiment 1, a support assembly 6 and a fastening assembly 7 are further provided. By using the support assembly 6, when the steel sleeve is sleeved on the end-sealing cylinder 4, the hydraulic rod 601 on it extends, and then the connecting sleeve 602 at its shaft end is pushed to abut against the inner wall of the steel sleeve. Through the fastening assembly 7, after the support assembly 6 supports and fixes the steel sleeve, the fastening spring strip 701 can be locked outside the port of the steel sleeve.

[0036] Specifically, the support assembly 6 is arranged in a circular array structure in the side groove 401 on the outer side of the end-sealing cylinder 4. And a spring rod 604 is arranged in the side groove 401 located in the lower middle of the end-sealing cylinder 4, and a hydraulic rod 601 is arranged in the side groove 401 located above the end-sealing cylinder 4. And connecting sleeves 602 are arranged at the shaft ends of the spring rod 604 and the hydraulic rod 601, and the connecting sleeves 602 are connected by an elastic sleeve plate 603.
