A suspension and damping multifunctional rotary impactor

Abstract

The invention provides a hanging and damping type multi-functional rotary impactor, which comprises a main body, a hanging and damping device and a hammering device, wherein secondary powder which is produced by utilizing external resistance is mutually intervened with main power which is produced by a drilling machine, the hanging and damping type multi-functional rotary impactor enables the main body and the hanging and damping device to be asynchronous by utilizing the structure and the working principle of a deep groove ball bearing, the work principle of the deep groove ball bearing is that the inner portion of the deep groove ball bearing rotates and the outer portion of the deep groove ball bearing does not rotate, or the outer portion of the deep groove ball bearing rotates and the inner portion of the deep groove ball baring does not rotate, clamping jaws of the hanging and damping device are clamped on a hole wall of the floor not to move, and a main shaft compels a driving hammer which is arranged in the inner portion of the drilling machine to rotate along with the main shaft and change rotary motion into straight motion along a mechanism which is arranged by being matched with a driving hammer spring and being driven by the drilling machine, thereby simply utilizing a mechanical mode to complete impact and vibration. Because the hanging and damping type multi-functional rotary impactor uses a pure mechanical type secondary powder source and utilizes the external resistance without power to achieve work, the hanging and damping type multi-functional rotary impactor does not need to additionally add accessory equipment and power, and is strong in universality, low in cost and simple in structure.

Description

technical field [0001] The invention relates to a suspension and damping multifunctional rotary impactor, especially a secondary power source generated by external resistance, which blocks the damping device independently suspended on the main shaft, and then generates lateral resistance, forcing it to be connected with the main shaft and placed on the main shaft. The hammer device in the rotary impactor produces impact and vibration; in order to achieve the working effect of impact, vibration and simultaneous rotary drilling. Background technique [0002] The multi-functional impactor with vibration, impact or simultaneous rotary impact can meet the working requirements of soft and hard soil layers. It is a high-efficiency geological drilling tool. At the same time, it has the ability to deal with accidents in drilling holes without adding additional facilities. , strong versatility and interchangeability, which is not available in the existing market.

Problems solved by technology

Similar impactors in the market mainly include pneumatic, hydraulic down-the-hole hammers, and ultrasonic vibration equipment. Their disadvantages are: they have no ability to deal with accidents, are poor in versatility, and bulky, and the equipment is expensive; The oil pressure is high, its adaptability to wind pressure and oil pressure is poor, and the pressure loss of compressed air or oil along the flow channel is large. With the increase of hole depth, the pressure is weakened, and the impact force and vibration frequency are greatly weakened. Work efficiency is greatly reduced, or even not working properly
