[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0025] like Figure 1-6 As shown, a pipeline impact resistance device includes a base plate 1, a support plate 2, a mounting seat 3 and a cover body 4, wherein the support plates 2 have two pieces and are respectively vertically mounted on the base plate 1, the mounting seat 3 is mounted on the two support plates 2, and the cover body 4 is mounted on the mounting plate. The upper end of the mounting seat 3 is provided with a first notch, and the lower end of the cover body 4 is provided with a second notch. The first notch and the second notch are combined to form a channel, and the natural gas pipeline is arranged in the channel to play a protective role. The upper end of the cover body 4 is provided with a conical top 403. When encountering a vertical impact from a drilling machine, the conical top 403 can first contact the drill bit and make it slip on the surface of the cover body 4, thereby preventing the drill bit from continuously impacting or directly penetrating the cover body 4, thereby accidentally damaging the natural gas pipeline.

[0026] In the above embodiment, buffer pads 5 are provided on both the first notch and the second notch. The buffer pads 5 are made of rubber. The natural gas pipeline is installed in the channel and is annularly covered by the buffer pads 5, so as to reduce the external impact and vibration transmitted to the natural gas pipeline and keep the natural gas pipeline firmly installed. The buffer pads 5 are in multiple pieces and are arranged axially along the channel. They are fully laid in the natural gas pipeline installation section to keep the natural gas pipelines in each section in a consistent state and balanced in force, so as to prevent the natural gas pipelines from being damaged due to local shaking caused by external impact force. The buffer pads 5 on the first notch and the second notch are staggered with each other. When the natural gas pipeline is installed, the buffer pads 5 will produce an axial offset relative to the channel under the impact of the natural gas pipeline, while the buffer pads 5 against the upper and lower parts of the natural gas pipeline can provide denser covering and support, so as to prevent the natural gas pipeline from breaking through the buffer pads 5 and avoid assembly failure.

[0027] In the above embodiment, lifting parts 401 are provided at both ends of the cover body 4 to facilitate lifting of the cover body 4; a positioning hole 301 is provided at the upper end of the mounting seat 3, and a positioning pin 402 is provided at the lower end of the cover body 4, and the positioning pin 402 can be embedded in the positioning hole 301 to enable the cover body 4 and the mounting seat 3 to be accurately assembled; the support plate 2 and the base plate 1 are detachably connected by screws, which is convenient and quick to manufacture components and assemble. In addition, the device also includes at least two fixing plates 6, which pass through and are installed on the base plate 1 obliquely from top to bottom. The space between the at least two fixing plates 6 is open downwards, which can be inserted into the soil layer and prevent the device from vertical displacement. Under the best use effect, there are four fixing plates 6, which are arranged at the four corners of the base plate 1 respectively. The space between the four fixing plates 6 is open downwards, which can prevent the base plate 1 from vertical displacement and lateral displacement, so that the base plate 1 is installed more firmly. A mounting groove 101 is provided on the base plate 1, and the fixing plate 6 is inserted and fixed in the mounting groove 101, and then locked by screws, which is convenient and quick. Compared with traditional expansion screws, this structure is more stable in the soil. The opening of the mounting groove 101 narrows from top to bottom, and the fixing plate 6 corresponds to the shape of the mounting groove 101, and the fixing plate 6 is automatically limited.

[0028] Description of the working method of this utility model:

[0029] In the key section of the natural gas transmission line, the soil layer is dug to form a groove, the bottom of the groove is tamped flat, and the bottom plate 1 is arranged at intervals at the bottom of the groove. The bottom plate 1 is fixed by passing the fixing plate 6 through the installation groove 101 and inserted into the soil layer, so as to provide a stable foundation for the installation of the natural gas pipeline; after the bottom plate 1 is fixed, the support plate 2 and the mounting seat 3 are installed in sequence, and the laying of the buffer pad 5 on the mounting seat 3 is checked. After confirmation, the natural gas pipeline is hoisted into the mounting seat 3, and the cover body 4 is hoisted onto the mounting seat 3 for installation, so that the mounting seat 3 and the buffer pad 5 in the cover body 4 form a full surround of the natural gas pipeline, which can not only ensure the stability of the entire section of the natural gas pipeline, but also weaken the external impact force through the buffer pad 5 to protect the natural gas pipeline. When the above-mentioned key section is located on the road, heavy vehicles, overloaded vehicles, etc. passing by will generate huge vibrations on the foundation, and the vibrations will continuously impact the device. Under the action of the buffer pad 5, part of the impact force can be weakened to prevent the natural gas pipeline from shaking violently under the impact, causing the pipeline to crack or be damaged at the welding part under repeated deformation, thereby protecting the safety of the natural gas pipeline; when excavating and reconstructing the road, the device can prevent the drill bit of the excavation equipment from directly impacting the natural gas pipeline, thereby causing a dangerous situation of natural gas leakage, and when sharp objects such as the drill bit impact the conical top 403 of the device, it will slip, avoiding direct impact on the device, and also facilitating the excavation personnel to find the natural gas pipeline in time.

[0030] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
