Description

Technical Field

[0001] This utility model belongs to the field of pipeline repair technology, and in particular relates to an underground cement pipe repair equipment. Background Technology

[0002] Underground cement pipes play an important role in municipal engineering, such as drainage and water supply. Damage to them may lead to functional failure, which in turn affects the normal operation of the city. This may result in the underground cement pipes being excavated and replaced to repair the pipes.

[0003] However, damage to underground cement pipes often occurs locally. Direct replacement would require extensive excavation, which is not only too costly but would also cause traffic congestion due to road construction, disrupting normal traffic flow. Therefore, it is necessary to provide underground cement pipe repair equipment to solve these problems. Utility Model Content

[0004] This utility model provides an underground cement pipe repair equipment, which aims to solve the problems mentioned in the background art, such as the high cost of repairing cement pipes by excavation and the traffic congestion caused by road construction.

[0005] To solve the above problems, this utility model is implemented as follows: an underground cement pipe repair device, comprising: a drilling rig and an octagonal connecting spindle connected to the drill rod of the drilling rig, wherein the octagonal connecting spindle is provided with a claw wheel assembly; a water channel provided on the drilling rig for flushing sand and soil on the claw wheel assembly; a bearing chamber fixed on the drilling rig, wherein a pipe guard ring is provided on the bearing chamber, and a pipe to be laid is provided on the pipe guard ring, wherein a pipe docking groove is provided on the inner wall of the pipe to be laid for docking the pipe; a male pull nose provided inside the pipe guard ring, wherein a female pull nose is provided on the male pull nose, wherein a pull rod is provided at one end of the female pull nose, wherein a concave-convex shaft is provided at one end of the pull rod, wherein a rear pressure cap for fixing the pipe is provided on the concave-convex shaft; and a pipe loading cylinder provided on the concave-convex shaft.

[0006] Preferably, the claw wheel assembly includes: a carbide grinding head and a spherical claw wheel disposed on an octagonal connecting spindle, wherein the carbide grinding head is used for clearing obstacles and the spherical claw wheel is used for grinding cement pipes.

[0007] Preferably, five claw wheel assemblies are evenly distributed; five carbide grinding heads are evenly distributed.

[0008] Compared with related technologies, the underground cement pipe repair equipment provided by this utility model has the following beneficial effects:

[0009] Compared with existing technologies, the underground cement pipe repair equipment provided in this solution mainly consists of an octagonal connecting spindle connected to the drill rod of the drilling rig, serving as the core of power transmission throughout the repair process. The pipe to be laid is carefully installed on the protective ring, and the connection between pipes cleverly utilizes the pipe's own pipe docking grooves to ensure the strength and stability of the connection. To facilitate the loading and docking of new pipes, the female pull lug is cleverly connected to the male pull lug, and then connected to the concave-convex shaft via a pull rod. The specially designed groove on the concave-convex shaft cleverly fixes the pipe loading cylinder, while the piston rod of the pipe loading cylinder presses against the rear pressure cap, thus tightly fitting and pressing against the pipe wall. When the piston rod extends, the generated reaction force can easily push the male clamp of the new pipe into the female clamp of the front pipe, achieving fast and stable pipe docking. The claw wheel assembly... The spherical claw wheels can not only grind hard surfaces such as rocks, but also easily handle obstacles such as cement pipes and cement blocks. During the hole enlargement process, the claw wheel assembly rotates along with the drill spindle. It is worth mentioning that the front and rear halves of the drill are cleverly separated through bearing chambers. The front half can rotate with the drill, while the rear half remains stationary, ensuring the stability and accuracy of the new pipeline during the connection process. In addition, the carbide grinding head on the claw wheel assembly is a key component for obstacle removal. Its powerful cutting and crushing capabilities can quickly remove obstacles in the pipeline. The water channel design further improves the repair efficiency. It can eject the water flow in the drill rod through the drill's water channel, which not only provides the necessary cooling effect for the carbide head, but also effectively washes away sand and debris on the claw wheels, ensuring the smooth progress of the repair work.
