Embodiment Construction

[0022] Such as figure 1 with figure 2 As shown, a mud scraping device of a static pile press is suitable for mud scraping of square pipe piles. It includes four movable scrapers 2 and the four scrapers 2 are arranged symmetrically in pairs. Enclosed into a square structure; the top of the scraper 2 is connected with a rotating drive device 3, which can be a rotating motor, and the bottom of the scraper 2 is provided with a scraper 21, the rotating drive device 3 can drive the scraper 2 around the scraper The top of the plate rotates to make the four scrapers 21 abut the square pipe pile 1 at the same time, thereby scraping the sludge on the wall of the square pipe pile 1; the present invention also includes a bracket 4 on which the rotation driving device 3 is installed.

[0023] The top of the scraper 2 is fixed with a shaft sleeve 22. The shaft sleeve 22 is provided with a rotating shaft 23. The shaft sleeve 22 and the rotating shaft 23 are splined. When the rotating shaft 23 r...

Abstract

The invention provides a mud scraping device of a static pile pressing machine. The mud scraping device comprises four scraping plates capable of moving, and a support, wherein a square is formed by the four scraping plates in a surrounding manner; the tops of the scraping plates are connected to rotary driving devices; scraping edges are arranged at the bottoms of the scraping plates; the rotarydriving devices can drive the scraping plates to rotate around the tops of the scraping plates, so that the four scraping edge are simultaneously pressed against a square pipe pile; and the rotary driving devices are arranged on the support. The mud scraping device is provided with the four scraping plates capable of rotating; when the four scraping plates are closed, the mud scraping device can scrape mud on the square pipe pile; and the mud scraping device can be applicable to pipe piles of different sizes by simultaneously controlling the rotating angles of the scraping plates and has strong applicability. The resistance to the square pipe pile can be eliminated by simultaneously loosening the four scraping plates, and thus, the high-efficiency press-in operation on the square pipe pileis facilitated.

Description

Technical field [0001] The invention belongs to the technical field of construction engineering equipment, and specifically relates to a mud scraper of a static pile driver. Background technique [0002] The static pile driver uses the static load generated by the hydraulic pressure to press the pile into the ground. Specifically, the static pile driver presses in, pulls out, and presses in the pile repeatedly to finally press the pile into the ground , That is: use the resistance of the pipe pile to be pulled out as the reaction force to apply a static load to the next pipe pile press-in, press the pile into the ground, so that a pressure bulb is formed at the bottom of the pipe pile, and the level and A strong structure can be formed in the vertical direction, so there will be no vibration, noise and pollution during construction, no damage to the pile, no impact, and little damage to the surface structure. [0003] In the process of pulling out the pipe pile, there is soil on t...
