Description

Digging component, walking mounting structure and square pile drill bit

Technical Field

The utility model belongs to the technical field of drilling equipment, and particularly relates to an excavating component, a walking installation structure and a square pile drill bit.

Background

In square pile construction, a round drill is generally used for pre-drilling, and the square pile is processed into a quincuncial pile-like shape. However, when the round drill bit is used for machining standard rectangular square piles, the round drill bit cannot machine the round drill bit at four corners of the pre-drilled holes. Special square pile drills are required to finish them.

The conventional square pile drill bit has the problems that the axial direction of the excavating wheel body is horizontal, namely, the excavating wheel body is arranged on two sides of a vertical plate, the vertical plate has the width of the excavating wheel body, and the excavating wheel body which is horizontally arranged cannot excavate in the width direction of the vertical plate due to the fact that excavating elements are not arranged. Thus, the entire depth of the middle riser portion of the square pile is not machinable, which is typically avoided by drilling with a round drill bit. Therefore, in the process of trimming the deep hole corners of the square piles, incomplete trimming of the square piles often occurs.

Since square pile sizes required to be processed in the market in the prior art are uniform and standard, for example, standard size specifications of length x width of 1.7 m x 2.2 m, 1.7 m x 2.5 m, 1.7 m x 2.7 m and the like are usually adopted, the square pile drill is usually designed and produced according to the square pile sizes. The adjustment of the machining allowance is usually performed by mounting the diamond knife on the excavating wheel, and by changing the mounting depth of the diamond knife, or by changing the specification of the excavating element (bullet head), or by changing the height of the mounting base surface of the excavating element (bullet head), fine adjustment of the machining size is performed. Because the sizes of square piles on the market are diversified, and the adjustment amount of the adjustment methods is small, the overall size of the processed square piles cannot be adjusted in a large range, and the production requirement cannot be met.

Meanwhile, most foundation piles which can be processed by the existing square pile drill bit are required to drill precast round holes for a plurality of times, and when the drilling of the first round hole is completed and the drilling of the residual round hole is carried out, the round drill bit is attached to the wall due to the fact that one side of the drilled round hole is free of earth stones, the defects of inclination and the like of the drilled round drill bit are easy to occur, and the defects of complex subsequent construction process, difficult construction and the like are caused. Therefore, the deep hole processing of the square pile can be realized by carrying out one-time round hole drilling on the square pile.

In summary, if a hydraulic square pile drill bit with a large deep hole cutting range for a working square pile and adjustable excavation size range for the square pile drill bit can be developed, the hydraulic square pile drill bit has a good industrial application prospect.
