Description

Technical Field

[0001] The utility model belongs to the technical field of slurry guiding devices, in particular to a casing slurry guiding device. Background Art

[0002] When the rotary drilling rig is operating, the drill bit needs to be repeatedly pulled out of the hole, so the grouting pipe cannot be hung directly on the top of the casing like a rotary drill using a drill rod to prevent the drill bit from scratching the slurry pipe.

[0003] In most cases, when a rotary drilling rig is in construction, a small pool is dug next to the casing, and a small hole is cut on the casing to connect the pool and the casing. The slurry is added in the pool and the slurry flows into the hole through the small hole to achieve the purpose of adding slurry. However, when encountering an operating environment with high civilized requirements such as elevated roads in the city, the cement on the construction site is often hardened and does not have the conditions to dig a small pool on the side. The traditional practice is: when slurry needs to be added during the construction of the rotary drilling rig, the pipe is manually placed in the hole for slurry addition, and then the pipe is manually pulled out after completion, which is very inconvenient. Later, the method of using wire to tie the pipe to the edge of the casing mouth was also used, but there is still trouble in disassembly and assembly. When the slurry is discharged, the large reaction force will cause the slurry to be discharged in a flat direction until the drill rod splashes all over the site. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art and provide a casing slurry guiding device which is easy to disassemble and assemble, avoids mud splashing on the site and is easy to install.

[0005] The purpose of the utility model is achieved through the following technical scheme. The casing slurry guiding device includes a shelf plate and a connecting unit. A through hole is provided on the plate wall of the shelf plate. The through hole is arranged obliquely downward along the height direction of the shelf plate. One end of the connecting unit is connected to the through hole by welding, and the other end of the connecting unit is connected to a mud pipe through a detachable unit. A shelf groove is provided on the bottom end surface of the shelf plate, and the shelf plate is plugged into the casing wall of the casing through the shelf groove.

[0006] The beneficial effects of the utility model are as follows: compared with the prior art, a shelf plate with a shelf groove is provided, and a through hole obliquely downward is provided on the shelf plate, which is welded and fixed to the connecting unit through the through hole, which has the advantages of easy disassembly and assembly, avoiding mud splashing on the site and facilitating installation.

[0007] Preferably, the core line of the through hole and the wall thickness line in the thickness direction of the shelf board are distributed at an angle of 45°, and one end of the through hole is connected to the inner wall of the shelf board, and the other end of the through hole is connected to the outer wall of the shelf board; through the 45° angle distribution of the through holes, the slurry discharge direction is obliquely downward, allowing the slurry to be sprayed directly into the hole, thereby avoiding mud splashing on the site.

[0008] Preferably, the shelf plate is arc-shaped and consistent with the shape of the casing wall of the casing; such a structural setting facilitates the shape of the shelf plate to be consistent with that of the casing, providing a better overall feel, and facilitates the formation of the shelf groove on the shelf plate.

[0009] Preferably, the shelf groove is in an arc shape and is consistent with the shape of the casing wall of the casing; this facilitates the shelf groove and the casing wall of the casing to be placed on each other, making assembly and disassembly more convenient.

[0010] Preferably, the connecting unit includes a connecting pipe and a connecting head, the connecting head is integrally formed on one end of the connecting pipe and is communicated with each other, and the other end of the connecting pipe is connected to the through hole by welding; through the arrangement of the above structure, the forming between the connecting pipe, the connecting head and the casing is more convenient, and the manufacturing is also more convenient.

[0011] Preferably, the connecting pipe is in the shape of a curved pipe, the bending angle of the connecting pipe is 90°, and one end of the connecting pipe where the connecting head is located faces the bottom of the shelf plate; through the arrangement of the above structure, the disassembly and assembly between the connecting head and the mud pipe is more convenient.
