Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering technology, and specifically relates to a municipal engineering piling device. Background Technology

[0002] Piling machines are primarily used in municipal engineering projects where pile foundations need to be installed under complex geological conditions. They create holes by rotating drill bits or spiral blades to cut the soil, simultaneously or in stages, inserting precast piles. Combined with high-pressure grouting, this further enhances the pile's side friction and end bearing capacity. Suitable for various soil types, including soft soil, gravel, and rock strata, this equipment boasts advantages such as low noise, high precision, and environmental friendliness. It efficiently completes the entire process of drilling, slag removal, pile installation, and reinforcement, making it a key technological tool in deep foundation pit support and foundation construction for urban elevated roads, subway excavations, and other similar projects.

[0003] During municipal pile foundation construction, the high-speed rotating drill bit generates a large amount of debris through intense friction with the soil. This slurry, mixed with clay, gravel, and groundwater, splashes everywhere under centrifugal force, forming a sticky residue that coats the surface of the transmission rod. As operations continue, this residue can cause quality problems such as lifting and lowering jams and positioning inaccuracies, or even safety hazards such as power overload and accelerated wear of structural components. This is particularly pronounced in silty soil layers with high water content, and in severe cases, it requires manual cleaning after machine shutdown, significantly reducing construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a municipal engineering piling device to solve the problem mentioned in the background art that the existing piling devices do not have the ability to clean the surface of the transmission pole.

[0006] Preferably, the mounting part includes a connecting part, the outer surface of which is fixedly connected to the mounting plate, thereby driving the mounting plate to rise and fall synchronously through the connecting part. The cleaning part is integrally disposed at both ends of the connecting part, so that the surface of the transmission rod can be cleaned during the rising and falling of the connecting part.

The entire cleaning assembly is threadedly connected to the transmission rod through the cleaning plate. The cleaning plate can lift itself up and down as the transmission rod rotates, thereby driving the mounting plate to lift up and down. In addition, it can rotate and clean out the impurities in the thread groove of the transmission rod together during rotation.

[0008] Preferably, the surface of the cleaning section is provided with discharge holes. These discharge holes are not parallel to the opening direction of the cleaning section, so as to prevent scraped impurities from directly entering the interior of the cleaning section through the discharge holes. The discharge holes are designed to discharge the impurities scraped by the cleaning blades inside the cleaning section.

[0009] Preferably, a spring is also installed on the bottom end face of the mounting bracket. The spring is sleeved on the transmission rod and contacts the end of the cleaning part located at the top of the connecting part. The spring enables flexible contact and avoids direct contact between the cleaning part and the mounting bracket, thus preventing collision.

[0010] Preferably, the bottom of the mounting bracket has a slot from top to bottom, into which a protective plate is inserted. A clamping bolt is screwed into the front surface of the mounting bracket, and the clamping bolt abuts against the side of the protective plate. The protective plate can separate splashed dirt from the servo motor.

[0011] Preferably, a hydraulic rod is also provided between the vehicle body and the mounting frame, and a bracket for supporting the mounting frame is also installed on the front part of the vehicle body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
