Problems solved by technology

[0005] However, it is troublesome to install and replace the hexagonal hole parts, especially the replacement of the hexagonal hole shaft of the hydraulic rock drill is more troublesome. There are gears installed on it, the machining accuracy of the shaft is high, and the keyway needs to be processed. The cost of the hexagonal hole shaft is still relatively high.
Just because the front part of the hexagonal hole shaft is worn at about 50mm, the entire shaft needs to be replaced, resulting in waste of resources and inconvenient replacement

Embodiment Construction

[0020] Examples such as Figure 1 to Figure 3 As shown, a new torque output structure for a hydraulic rock drill includes a drill rod 14, a hexagonal hole shaft 9 is coaxially mounted on the drill rod 14, and a precursor 1 is coaxially mounted on the hexagonal hole shaft 9 near the end. , the front body 1 is provided with a hexagonal sleeve 10 for easy replacement near the end of the hexagonal hole shaft 9 .

[0021] The hexagonal sleeve 10 is detachably assembled coaxially with one end of the hexagonal hole shaft 9, and a hexagonal hole capable of accommodating the drill rod 14 is opened in the hexagonal sleeve 10, which is convenient for replacement and saves cost.

[0022] The length of the hexagonal sleeve 10 along its own axis is 45-60 mm, which is more conducive to saving materials and costs and reducing unnecessary waste.

[0023] The hexagonal sleeve 10 has a plurality of holes A on the hexagonal sleeve in an annular array on one end surface close to the hexagonal hol...

Abstract

The invention discloses a novel hydraulic drill torque output structure which comprises a drill rod. A hexagonal hole shaft is coaxially assembled on the drill rod, a front body is coaxially assembledat a position, close to the end, of the hexagonal hole shaft, and a conveniently replaced hexagonal sleeve is arranged in the front body and at a position close to the end of the hexagonal hole shaft. By the aid of the conveniently replaced hexagonal sleeve, the novel hydraulic drill torque output structure is more convenient to maintain and replace, maintenance workload is reduced, maintenance time is saved, the size of a component needing replacement is reduced, materials are saved by 75% or more, and the use cost of users is reduced by 80%.

Description

technical field [0001] The invention belongs to the field of engineering machinery, and in particular relates to a novel torque output structure for hydraulic rock drills used in mining, highway, railway, water conservancy and tunnel construction projects. Background technique [0002] At present, in my country's mining, high-speed rail, subway tunnels, and water conservancy construction, air-leg pneumatic rock drills are widely used, with an annual demand of more than 100,000 units and more than 350,000 employees. The advantages of pneumatic rock drills are: simple structure, low price, less strict sealing requirements, and less professional maintenance. The disadvantages are low energy utilization, high vibration, high noise, and oil and gas pollution, threatening the physical and mental health of miners. [0003] The hydraulic rock drill is an energy-saving and environment-friendly rock drill. Its characteristics are: fast rock drilling speed, low noise, no oil mist pol...
