Therefore, the existing sand cylinder is not only complex in installation process, but also troublesome in disassembly.

[0004] Therefore, it is necessary to provide a large-diameter steel pipe column support unloading sand cylinder. CONTENT OF THE INVENTION

[0005] In order to solve the problem that the existing large-diameter steel pipe column support unloading sand cylinder is inconvenient to disassemble and assemble, the application provides a large-diameter steel pipe column support unloading sand cylinder.

[0006] The application provides a large-diameter steel pipe column support unloading sand cylinder, which adopts the following technical scheme: comprising a lower cylinder and an upper column, the bottom end of the lower cylinder is provided with a lower flange, the lower flange is provided with a lower connecting hole, the top end of the lower cylinder is provided with an upper flange, and the upper flange is provided with an upper connecting hole.

[0007] The bottom end of the upper column is inserted into the lower cylinder and abuts against the inner wall of the lower cylinder, a sand pouring cavity is formed between the bottom end of the upper column and the inner wall of the lower cylinder, a sand outlet hole opening to the outside is formed in the cavity wall of the sand pouring cavity, the top end of the upper column is provided with a lug, the lug is provided with a hanging hole, one end of a screw rod can be screwed with a nut through the hanging hole, the other end of the screw rod can be screwed with a nut through the upper connecting hole, and the lug and the upper flange are abutted between the nuts at the two ends of the screw rod.

[0008] By adopting the above technical solution, when installing the sand cylinder, the user can first fix the lower flange of the lower cylinder to the top support of the disc buckle bracket with bolts and nuts, and then use one end of the screw rod to pass through the hanging hole and screw it to the nut, and the other end of the screw rod to pass through the upper connecting hole and screw it to the nut, so that the hanging lug and the upper flange can be abutted between the nuts at both ends of the screw rod, thereby strengthening the stability between the upper column and the lower cylinder in the horizontal direction; when disassembling, the user can also first remove the screw rod between the lower cylinder and the upper column, then release the sand inside the sand cylinder from the sand filling hole, and finally remove the bolts on the lower flange to complete the disassembly of the large-diameter steel pipe column support sand cylinder, thus enabling the large-diameter steel pipe column support sand cylinder to be quickly disassembled and assembled.

[0009] Specifically, the bottom of the lower cylinder is provided with external reinforcing ribs.

[0010] By adopting the above technical solution, the external reinforcing ribs can enhance the strength of the bottom of the lower cylinder.

[0011] Specifically, the upper column is a hollow column, and internal reinforcing ribs are provided between the inner side wall and the inner bottom wall of the hollow column.

[0012] By adopting the above technical solution, the internal reinforcing ribs can enhance the strength of the upper column.

[0013] Specifically, a ring of abutting protrusions is provided on the upper column near the bottom end, the abutting protrusions abut against the inner wall of the lower cylinder, and a ring of gusset plates is provided circumferentially between the top of the abutting protrusions and the upper column.

[0014] By adopting the above technical solution, the gusset plate can strengthen the connection between the abutment protrusion and the column body of the upper column.

[0015] Specifically, it also includes a sand passage pipe and a sealing component. One end of the sand passage pipe is connected to the sand outlet hole, and the sealing component is located on the other end of the sand passage pipe and can block the sand passage pipe.

[0017] Furthermore, the outer wall of the sand passage pipe is provided with external threads, and the sealing member is a cylindrical cap. The inner wall of the cylindrical cap is provided with internal threads that are compatible with the external threads of the sand passage pipe, and the end of the sand passage pipe away from the lower cylinder can be inserted into the opening of the sealing member and screwed into the sealing member.

[0018] By adopting the above technical solution, users can connect or separate the sealing component and the sand passage pipe by rotating the sealing component.

[0019] Furthermore, the sealing component includes a clamp and a plug. The clamp is tightly fitted onto the cylinder body of the lower cylinder. One end of the plug is connected to the inner ring of the clamp, and the other end of the plug is inserted into the sand passage pipe and abuts against the inner wall of the sand passage pipe.

[0020] By adopting the above technical solution, users can control the flow of sand through the pipe by installing or removing clamps.

[0021] Furthermore, the cavity wall of the sand filling chamber is provided with multiple sand outlet holes along the circumference of the lower cylinder, and each sand outlet hole is provided with a sand passage pipe. The inner ring of the clamp is provided with multiple blocking blocks, and each blocking block corresponds to a sand passage pipe. When the clamp is tightly clamped to the cylinder body of the lower cylinder, each blocking block is inserted into the corresponding sand passage pipe.

[0022] By adopting the above technical solution, when releasing sand, the user can open multiple sand pipes at the same time by removing the clamps, without having to spend time and effort to screw on the cylindrical caps on each sand pipe one by one.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] The device includes a lower cylinder and an upper column. The lower cylinder has a lower flange at its bottom with a lower connecting hole, and an upper flange at its top with an upper connecting hole. The bottom of the upper column is inserted into the lower cylinder and abuts against its inner wall, forming a sand-filling cavity between the bottom of the upper column and the inner wall of the lower cylinder. A sand outlet hole is provided on the wall of the sand-filling cavity. The top of the upper column has a lug with a mounting hole. One end of a screw rod passes through the mounting hole and is screwed into a nut, while the other end passes through the upper connecting hole and is screwed into a nut. The lug and the upper flange are then abutted between the nuts at both ends of the screw rod, allowing the user to easily install the sand cylinder. The lower flange of the lower cylinder can be fixed to the top support of the disc buckle bracket using bolts and nuts. Then, one end of the screw rod is threaded through the hook hole and screwed into the nut, and the other end of the screw rod is threaded through the upper connecting hole and screwed into the nut. This allows the lug and the upper flange to abut against the nuts at both ends of the screw rod, thereby strengthening the stability between the upper column and the lower cylinder in the horizontal direction. During disassembly, the user can first remove the screw rod between the lower cylinder and the upper column, then release the sand inside the sand cylinder through the sand filling hole, and finally remove the bolts on the lower flange to complete the disassembly of the large-diameter steel pipe column support sand cylinder, thus enabling quick assembly and disassembly of the large-diameter steel pipe column support sand cylinder.

The lower cylinder 1 has a lower flange 11 at its bottom end. A grid-shaped outer reinforcing rib 13 is provided between the inner ring of the lower flange 11 and the bottom of the lower cylinder 1. A triangular reinforcing rib is provided between the top of the lower flange 11 and the cylinder wall of the lower cylinder 1 to strengthen the bottom of the lower cylinder 1 and the strength between the lower cylinder 1 and the lower flange 11. A ring of lower connecting holes 111 is circumferentially opened along the upper edge of the lower flange 11. An upper flange 12 is provided at the top of the lower cylinder 1, with a ring of upper connecting holes circumferentially opened along the upper edge of the upper flange 12. The upper column 2 is a hollow cylindrical column with its opening at the top. A grid-shaped inner reinforcing rib 21 is provided between the inner side wall and the inner bottom wall of the hollow column to strengthen the upper column 2. A ring of abutment protrusions is provided on the column body of the upper column 2 near its bottom end. 24. The bottom end of the upper column 2 is inserted into the lower cylinder 1 and abuts against the inner wall of the lower cylinder 1 through the abutment protrusion 24. A ring of gusset plates 22 is provided circumferentially between the top of the abutment protrusion 24 and the column body of the upper column 2 to strengthen the connection between the abutment protrusion 24 and the column body of the upper column 2. A sand-filling cavity is formed between the bottom end of the upper column 2 and the inner wall of the lower cylinder 1. Four sand outlet holes leading to the outside are opened on the cavity wall of the sand-filling cavity along the circumference of the lower cylinder 1. Each sand outlet hole has... A sand-passing pipe 3 is provided, with one end of each sand-passing pipe 3 connected to a sand outlet hole, and the other end of each sand-passing pipe 3 having an external thread. The sealing member 4 is a cylindrical cap, and the inner wall of the cylindrical cap has an internal thread that matches the external thread of the sand-passing pipe 3. The end of the sand-passing pipe 3 away from the lower cylinder 1 can be inserted into the opening of the sealing member 4 and screwed into the sealing member 4, so that the user can connect or separate the sealing member 4 and the sand-passing pipe 3 by rotating the sealing member 4.

[0033] See Figure 2 and Figure 3 The top of the upper column 2 is provided with a ring of hanging ears 23, and each hanging ear 23 is provided with a hanging hole. The hanging ears 23 correspond one-to-one with the upper connecting holes. One end of the screw can pass through a hanging hole and be screwed with a pair of nuts to make the pair of nuts clamp the hanging ear 23. The other end of the screw can pass through an upper connecting hole corresponding to the hanging ear 23 and be screwed with a pair of nuts to make the pair of nuts clamp the upper flange 12, and fix the hanging ear 23 and the upper flange 12 between the nuts located at both ends of the screw.

[0034] The usage process of the first embodiment of this application is as follows:

[0035] When installing the sand cylinder, the user can first fix the lower flange 11 of the lower cylinder 1 to the top support of the disc buckle bracket using bolts and nuts. Then, one end of the screw rod passes through the hook hole and is screwed to the nut, and the other end of the screw rod passes through the upper connecting hole and is screwed to the nut. This allows the hanging lug 23 and the upper flange 12 to abut against the nuts at both ends of the screw rod, thereby strengthening the stability between the upper column 2 and the lower cylinder 1 in the horizontal direction. When disassembling, the user can first remove the screw rod between the lower cylinder 1 and the upper column 2, then release the sand inside the sand cylinder from the sand filling hole, and finally remove the bolts on the lower flange 11 to complete the disassembly of the large-diameter steel pipe column support sand cylinder, thus enabling the large-diameter steel pipe column support sand cylinder to be quickly disassembled and assembled.

[0036] See Figure 4 and Figure 5 In the second embodiment, the sealing component 4 includes a clamp 41 and four plugs 42. The four plugs 42 are equally spaced on the inner ring of the clamp 41. The four plugs 42 correspond one-to-one with the four sand-passing pipes 3. When the clamp 41 is tightly clamped on the cylinder body of the lower cylinder 1, the other end of each plug 42 is inserted into a corresponding sand-passing pipe 3 and abuts against the inner wall of the sand-passing pipe 3. This allows the user to open multiple sand-passing pipes 3 at the same time to release sand by disassembling the clamp 41, without having to spend time and effort to screw on the cylindrical caps of each sand-passing pipe 3 one by one.

[0037] It should be noted that the above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
