Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grinding devices, in particular to a high-efficiency pile head grinding device. Background Art
[0002] After the pile foundation construction is completed, 30% and no less than 20 engineering piles must be sampled for low-strain testing according to the specifications. Before low-strain testing, the pile head needs to be polished. In order to ensure the accuracy of pile foundation testing, the sensor installation point needs to be polished and smooth. Low-strain testing plays a vital role in the pile foundation acceptance process.
[0003] When a traditional pile head grinder is working, the operator needs to manually control the force and angle of the grinding wheel, which makes it difficult to maintain stable operation. The precision control of the pile head grinder is relatively difficult, and it is difficult to achieve high-precision grinding effects. In addition, due to the contact between the high-speed rotating grinding wheel and the pile head, a large noise will be generated, which will not only affect the operator's hearing health, but may also cause noise pollution to the surrounding environment and personnel. Secondly, during the grinding process, impurities and concrete particles on the surface of the pile head will be ground down to form dust. This dust will not only affect the operator's line of sight, but may also be inhaled into the respiratory tract, posing a threat to physical health. Therefore, it is necessary to provide an efficient pile head grinding device to solve the above problems. Utility Model Content
