Pipe pile core digging machine

Abstract

The invention discloses a pipe pile core digging machine. The pipe pile core digging machine comprises a mounting frame, wherein a driving device is arranged in the middle of the top of the mounting frame, a driving shaft is arranged at the output end of the driving device, spiral drill rods connected with each other are arranged at the bottom of the driving shaft, mounting discs are arranged on the two sides of the mounting frame, and the middle positions of the sides, away from each other, of the two mounting discs are sleeved with rotating columns. According to the pipe pile core digging machine, through mutual cooperation of telescopic positioning assemblies, two operators can step on treading positioning frames to force the multiple sections of stainless steel telescopic rods to stretch out and draw back during drilling and pile cleaning work by using the spiral drill rods, and the treading positioning frames are promoted to be attached to the ground at a required inclination angle through movable cooperation of hinge seats to form positioning support, at the moment, the spiral drill rods can be driven into a pile core to conduct pile cleaning operation by means of the telescopic characteristic of the multiple sections of stainless steel telescopic rods, the balance effect of two operators on height lifting of the core digging machine is better, and cooperation between the two operators is provided.

Description

technical field [0001] The invention relates to the technical field of coring machines, in particular to a pipe pile coring machine. Background technique [0002] The pipe pile is a hollow cylindrical slender concrete prefabricated component made by pretensioning prestressing process and centrifugal forming method. It is mainly composed of cylindrical pile body, end plate and steel ferrule. It is a high-strength concrete pile produced by pretensioning centrifugal technology. It has been widely used in the foundation treatment of high-rise buildings. After the pipe pile is statically pressed and piled, the soil will enter the pile core from the bottom, and it needs to be excavated at this time. The core machine takes out the soil to clean the inner core of the pipe pile. [0003] When the current coring machine is in actual use, two operators often support the supporting frame of the coring machine at the same time, and maintain balance and use the spiral blade to drill into...

AI Technical Summary

Problems solved by technology

[0003] When the current coring machine is in actual use, two operators often support the supporting frame of the coring machine at the same time, and maintain balance and use the spiral blade to drill into the soil and bring it out. However, when the coring machine is manually lifted and lowered The operation is extremely difficult, and the cooperation of the two operators is required, which makes it difficult for the coring machine to maintain a good balance for coring work, which is easy to cause damage to the inner wall of the tube, and at the same time increases the wear of the helical blade of the coring machine and reduces The service life of the components; when the operator holds the supporting frame of the coring machine, the height of the coring machine needs to be changed, which makes it difficult for the supporting frame to grasp stably as the device descends, which is not convenient for the operator to exert force. However, it is difficult to adjust the angle of the armrest frame, which increases the limitation and inconvenience of the use of the coring machine. When the coring machine is working, it will produce a shaking reaction during the drilling into the soil, which will vibrate the whole device and easily lead to dislocation of the coring structure. Reduce the stability of the operation of the device, and when using the helical blade to drill holes, if one of the operators slips and makes a mistake, the position of the corer is tilted, and the blade will continue to rotate at this time, which is extremely prone to accidents and reduces the use of the device. security
