本申请要求在2017年12月20日提交中国专利局、申请号为201711386023.0、发明名称为“一种封闭式水压凿岩机”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。The present application claims priority to Chinese Patent Application No. JP-A No. No. No. No. No. No. No. No. No. No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No No .
本发明实施例涉及但不限于一种水压凿岩机，具体地说涉及一种使用在矿山开采、公路、铁路、水利、隧道建设工程中的封闭式水压凿岩机，属于工程机械领域。The embodiment of the invention relates to, but is not limited to, a hydraulic rock drill, in particular to a closed hydraulic rock drill used in mining, road, railway, water conservancy and tunnel construction projects, belonging to the field of engineering machinery.
目前在我国矿山开采、高铁、地铁隧道、水利建设中，大量使用气动凿岩机，年需求量在10万台以上，从业人员达到35万以上。气动凿岩机已有100多年的发展与应用历史，但除机具结构、材质及其它一些改进外，能量利用率一直得不到实质性提高，振动大、噪声高等问题也始终无法解决。At present, in China's mining, high-speed rail, subway tunnels, and water conservancy construction, a large number of pneumatic rock drills are used, with an annual demand of more than 100,000 units and more than 350,000 employees. Pneumatic rock drill has more than 100 years of development and application history, but in addition to the structure, material and other improvements of the machine, the energy utilization rate has not been substantially improved, and the problems of large vibration and high noise have not been solved.
20世纪70年代投入市场的液压凿岩机以中、高压液压油作为能量传递介质，设备输出功率大、破岩效率高、能耗低、寿命长、工作环境好、易于自动控制，在世界范围内获得了迅速推广，然而由于机型重、推力大，必须安放在相应的液压钻车上才能发挥其效率，因此，液压凿岩机主要应用于大断面的巷(隧)道掘进中。其次，液压凿岩机及台车造价高、使用成本高、对操作者的技能要求高、维修技术要求高，限制了它在矿山开采、公路、铁路、水利、隧道建设工程中的应用。因此，在大部分中、小型采掘及地下工程建设中仍在大量使用气腿式气动凿岩机，而液压凿岩机的使用量不及它的1％。The hydraulic rock drill put into the market in the 1970s uses medium and high pressure hydraulic oil as the energy transmission medium. The equipment has high output power, high rock breaking efficiency, low energy consumption, long service life, good working environment and easy automatic control. It has been rapidly promoted. However, due to the heavy weight and large thrust, it must be placed on the corresponding hydraulic drill to achieve its efficiency. Therefore, the hydraulic rock drill is mainly used in the tunneling of large sections. Secondly, hydraulic rock drills and trolleys have high cost, high cost of use, high skill requirements for operators, and high maintenance technical requirements, which limits its application in mining, road, railway, water conservancy and tunnel construction projects. Therefore, the gas-legged pneumatic rock drill is still widely used in most of the medium and small-scale mining and underground construction, and the hydraulic rock drill is used less than 1%.
大量的气腿式气动凿岩机的使用一方面消耗大量的能源，增加了矿山生产成本，另一方面噪声超过125dB(A)及强烈的振动和大量的油污，使大量的从业人员患上耳聋、白手病等职业疾病，严重威胁着矿工的身心健康。The use of a large number of air-legged pneumatic rock drills consumes a large amount of energy on the one hand, increasing the production cost of the mine. On the other hand, the noise exceeds 125dB (A) and the strong vibration and a large amount of oil pollution, causing a large number of employees to suffer from deafness and white hands. Occupational diseases such as diseases seriously threaten the physical and mental health of miners.
