They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example 1

[0023] Reference Figures 1 to 3 A steel sand bucket support platform for pipeline installation includes: a sand bucket 1, a support platform 2 with its bottom located inside the sand bucket 1, two lifting devices symmetrically arranged on both sides of the sand bucket 1 3, a vertical guide device on the outer wall of the sand bucket 1 4, and dry sand 5 between the sand bucket 1 and the support platform 2.

[0024] The lower section of the side wall of the sand bucket 1 has several sand guide holes 13, and sand-blocking bolts 15 are fitted inside the sand guide holes 13. The support platform 2 includes a support base 21 located inside the sand bucket 1 and an arc-shaped load-bearing platform 22 located on top of the support base 21. The support base 21 is a closed cavity. The lifting device 3 includes: a support rod 31 with one end hinged to the bottom of the arc-shaped load-bearing platform 22, a pressure rod 32 with one end hinged to the unused end of the support rod 31, and a telescopic handle 33 fixedly connected to the unused end of the pressure rod 32. The middle section of the pressure rod 32 is rotatably connected to the sand bucket 1. In this embodiment, the support base 21 is welded from a φ400*12mm steel pipe and a 12mm steel plate, and the arc-shaped load-bearing platform 22 is made of a 1cm thick ordinary steel plate and processed into an arc-shaped load-bearing platform 22 that matches the outer diameter of the installed pipe. In this embodiment, a rubber pad 23 with a thickness of 10mm is provided on the upper surface of the arc-shaped load-bearing platform 22.

[0025] Preferably, in this embodiment, two sets of vertical guide devices 4 are provided, and the two sets of vertical guide devices 4 are arranged symmetrically. The vertical guide device 4 includes a guide seat 41 provided on the outer wall of the sand bucket 1 and a guide rod 42 sleeved on the guide seat 41; the top of the guide rod 42 is fixedly connected to the arc-shaped support platform 22; the guide rod 42 is vertically downward. This can prevent the support platform 2 and the sand bucket 1 from undergoing horizontal displacement when the pressing rod 32 lifts the support platform 2 through the support rod 31, and at the same time prevent the angle of the support platform 2 from changing.

[0026] Preferably, in this embodiment, the sand bucket 1 includes a bucket body 11 and a bucket bottom 12 fixedly connected to the bottom of the bucket body 11. A sand guide hole 13 is located in the lower section of the bucket body 11. An annular thickened plate 14 is provided around the sand guide hole 13 on the bucket body 11. The thickened plate 14 has an internal thread on its inner ring. It should be noted that the sand guide hole 13 has an internal thread, and the sand-blocking bolt 15 has an external thread matching this internal thread. In this embodiment, a φ500*6mm steel pipe is used for the bucket body 11, and a 6mm thick ordinary steel plate is used for the bucket bottom 12. Two holes are evenly spaced 125cm from the bottom of the sand bucket 1. These holes are the sand guide holes 13, with a diameter of φ28mm. The thickened plate 14 is made of 1cm thick ordinary steel plate, and the sand-blocking bolt 15 is made of A28 round steel with threaded construction, facilitating the removal of dry sand from the bucket.

[0027] Preferably, in this embodiment, the two lifting devices 3 are symmetrically arranged on both sides of the pipe. During operation, the lifting devices 3 can be operated from the side of the pipe, unlike operating from the bottom, thus avoiding limited operating space. In this embodiment, the support rod 31 and pressure rod 32 of the lifting device 3 are both made of 80 channel steel. The support rod 31 is hinged to the arc-shaped support platform 22 via a hinge bolt 35 and a hinge frame 36. The hinge frame 36 is located at the bottom of the arc-shaped support platform 22. The support rod 31 and pressure rod 32 are hinged via the hinge bolt 35; the hinge bolt 35 is made of A16 round steel.

[0028] In this embodiment, when using a steel sand bucket support platform for pipe installation, firstly, according to the actual pipe installation height on site, a certain amount of dry sand 5 is filled into the sand bucket 1. Then, the arc-shaped support platform 22 is raised to match the installation height of the steel pipe using two lifting devices 3. Specifically, the arc-shaped support platform 22 is raised by pressing down the pressure rod 32 and then by supporting the support rod 31. At this time, dry sand 5 is continued to be filled until the sand bucket 1 is full. After it is completely filled, the pipe installation is carried out. One steel pipe is temporarily supported by two steel sand bucket support platforms. After the steel pipe is installed, the dry sand inside the sand bucket 1 can be removed by removing the sand-blocking bolts 15. After lowering the height of the arc-shaped support platform 22, the steel sand bucket support platform for pipe installation can be removed and transported to the next section for installation construction. Example 2

[0029] Based on Example 1, please refer to Figure 1 , Figure 2 and Figure 4 As a preferred embodiment, the telescopic handle 33 includes: an inner sleeve 331 fixedly connected at one end to the pressure rod 32, an outer sleeve 332 fitted onto the inner sleeve 331, and a limiting bolt 333; the inner sleeve 331 has several equidistantly arranged through holes, the lower section of the outer sleeve 332 has a through hole, and the limiting bolt 333 passes through the through holes on the outer sleeve 332 and the inner sleeve 331 in sequence. The overlap length between the outer sleeve 332 and the inner sleeve 331 can be controlled, thereby changing the length of the telescopic handle 33 and reducing the labor intensity of operating the lifting device 3. Example 3

[0030] Based on Example 2, please refer to 1 to 2019. Figure 3 Preferably, in this embodiment, the middle section of the pressure rod 32 is rotatably connected to the outer wall of the sand bucket 1 via a hinge bolt 35; one end of the hinge bolt 35 is fixedly connected to the outer wall of the sand bucket 1; a support frame 34 is fixedly connected to the hinge bolt 35, the support frame 34 including an upper inclined brace with one end fixedly connected to the upper end of the hinge bolt 35 and the other end fixedly connected to the outer wall of the sand bucket 1, and a lower inclined brace with one end fixedly connected to the lower end of the hinge bolt 35 and the other end fixedly connected to the outer wall of the sand bucket 1. By supporting the hinge bolt 35 with the support frame 34, bending of the hinge bolt 35 after repeated use can be avoided.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
