Technical Field

[0001] This utility model relates to the field of gas pipe technology, specifically a gas pipe excavation expansion and contraction protection device. Background Technology

[0002] Gas is a general term for gaseous fuels that can burn and release heat for use by residents and industrial enterprises. For safety reasons, gas pipelines are usually buried underground. During gas pipeline maintenance, they need to be excavated for maintenance operations, and protective measures must be taken during the excavation process.

[0020] Furthermore, the locking post 416 is slidably connected to the connecting box 414, and the limiting plate 411 and the locking post 416 are provided with grooves at corresponding positions, and the locking post 416 is inserted into the groove, which makes the adjustment process more stable.

[0021] Furthermore, the mounting assembly 42 includes a first connecting plate 421, which is fixedly connected to the bottom of the slider 412. A connecting post 422 is fixedly connected to the bottom of the first connecting plate 421, and a sliding post 423 is fixedly connected to the bottom of the first connecting plate 421.

Example 2:

[0023] Based on Example 1, please refer to Figure 6-7 Furthermore, in conjunction with Embodiment 1, the auxiliary limiting mechanism 5 includes a connecting platform 51, which is fixedly connected to the bottom of the connecting frame 424.

[0025] In actual operation, when this device is used, the threaded rod is first used as a T-type threaded rod to give it self-locking properties. The operator moves the device to the designated location for use in the gas pipeline excavation, and then adjusts it according to the operating environment. The operator uses a hex wrench to rotate the double-ended threaded rod 52. The rotation of the double-ended threaded rod 52, in conjunction with the limiting rod 55, causes the clamping frame 53 to move, thereby satisfying the installation of the second connecting plate 54. The locking bolts are then used to complete the installation between the second connecting plate 54 and the first flexible protective plate 2. After installation, the operator pulls the sliding sleeve 426.

The sliding sleeve 426 moves along the inclined groove, and the connecting frame 424 is inserted into the outside of the sliding column 423 until the insertion column 425 and the connecting column 422 are inserted. Then, the sliding sleeve 426 is released, and under the action of the second spring 427, the limiting ball 428 contacts the insertion column 425, thereby satisfying the quick installation and disassembly of the connecting frame 424. After installation, the worker squeezes the sliding plate 415. The movement of the sliding plate 415, in conjunction with the first spring 417, causes the locking column 416 to move. The sliding block 412 slides inside the mounting frame 1, causing the mounting plate 413 to move until it contacts the inner wall of the gas pipe excavation pipeline. Then, the sliding plate 415 is released, and under the action of the first spring 417, the locking column 416 is inserted into the limiting plate 411.
