The pipeline 1 is welded to the pipe shoe 2, and the pipeline 1 is installed on the platform through the pipe shoe 2. The guiding and limiting block 3 is located on both sides of the pipe shoe 2.

[0024] The cross-section of the guiding and limiting block 3 is in the shape of an elephant's trunk, with a simple structure and low manufacturing cost. It includes a front guiding surface 11, a limiting surface 12, a rear guiding surface 13, a connecting surface 14, a welding surface 15, and a contour surface 16. The front guiding surface 11, the limiting surface 12, the rear guiding surface 13, the connecting surface 14, the welding surface 15, and the contour surface 16 are connected end to end in sequence. The front guiding surface 11 and the rear guiding surface 13 are parallel, the limiting surface 12 is perpendicular to the front guiding surface 11 and the rear guiding surface 13 respectively, and the limiting surface 12 is located below the contour surface 16. The welding surface 15 is welded to the platform.

[0025] The connecting surface 14 includes a first extension section 141, a second extension section 142, and a connecting section 143. The first extension section 141 extends upward along the inner side of the welding surface 15, the second extension section 142 extends backward along the inner side of the rear guiding surface 13, and the first extension section 141 is connected to the second extension section 142 through an extension section. The first extension section 141 is perpendicular to the second extension section 142, and the connecting section 143 is inclined at 45°. The first extension section 141, the second extension section 142, and the connecting section 143 jointly form a working space convenient for welding the welding surface 15, greatly expanding the working space for welding the welding surface 15 and reducing the working difficulty of welding the welding surface 15. And the connecting section 143 is inclined at 45° to connect the first extension section 141 and the second extension section 142, increasing the strength of the guiding and limiting block 3. The limiting surface 12 and the front guiding surface 11 play the roles of limiting and guiding respectively. The connection between the second extension section 142 and the rear guiding surface 13 adopts an arc transition connection to avoid problems such as force deformation and reduced bearing capacity caused by a right angle at the connection.

[0026] The limiting surface 12 includes a first limiting section 121 and a second limiting section 122. The two ends of the first limiting section 121 are respectively connected to the front guiding surface 11 and the second limiting section 122, and the second limiting section 122 is perpendicularly intersected with the rear guiding surface 13. The included angle between the first limiting section 121 and the front guiding surface 11 is 45°. The first limiting section 121 prevents knocking against the pipe shoe 2. The second limiting section 122 is at 45°, preventing knocking against the welding position of the pipe shoe 2, facilitating the installation of the pipe shoe 2, causing stress concentration problems, and causing irreparable damage to the pipe shoe 2.

[0027] The pipe shoe 2 includes a support rod 21 and a base 22, and the support rod 21 is welded to the base 22; the support rod 21 is perpendicular to the base 22, and the support rod 21 and the base 22 are in a T shape. The pipe shoe 2 includes a side surface 23 and a bottom surface 24, and the side surface 23 and the bottom surface 24 intersect perpendicularly; the distance between the front guiding surface 11 and the side surface 23 is 3 mm, the distance between the limiting surface 12 and the bottom surface 24 is 3 mm, and the distance from the first limiting section 121 to the weld surface between the support rod 21 and the base 22 is 3 mm. It meets the requirement of the functional gap that the original distance between the front guiding surface 11 and the side surface 23 is 3 mm, the distance between the limiting surface 12 and the bottom surface 24 is 3 mm, and the distance from the first limiting section 121 to the weld surface between the support rod 21 and the base 22 is 3 mm, and also meets the requirement of expanding the welding operation space through the first extension section 141, the second extension section 142 and the connecting section 143.

[0028] There are multiple guiding and limiting blocks 3, and the multiple guiding and limiting blocks 3 are evenly distributed along the direction of the base 22, and a buffer assembly is provided between two adjacent guiding and limiting blocks 3. The buffer assembly includes two fixed beams 31 and a pulley 32, and the pulley 32 is connected between the two fixed beams 31 through a connecting shaft. Both ends of the fixed beam 31 are provided with convex parts, and the guiding and limiting block 3 is provided with a groove 33, and the convex parts are adapted to the groove 33. The pulley 32 can make the pipe shoe 2 move more smoothly during the movement process, preventing the pipe shoe 2 from contacting the guiding and limiting block 3 to generate concentrated stress, resulting in damage to the pipe shoe 2 or the guiding and limiting block 3.

[0029] The contour surface 16 includes a top surface section 161 and a side surface section 162, and the top surface section 161 and the side surface section 162 intersect perpendicularly; the top surface section 161 is located above the front guiding surface 11, and the side surface section 162 is located outside the rear guiding surface 13. The length of the top surface section 161 is three - quarters of the length of the bottom surface 24, and the length of the side surface section 162 is one - half of the side length.

[0030] The utility model realizes the purpose of being able to first position and install the pipeline and the pipe shoe 2, and then weld the two guiding and limiting blocks 3, greatly optimizing the installation construction difficulty and saving energy and reducing consumption.
