Description

Technical Field

[0001] The invention belongs to the technical field of lifters, in particular to a hollow water-passing and air-transmitting lifter. Background Art

[0002] The lifter is a key component used to lift and hang drill pipes and drilling tools in engineering machinery such as rotary drilling rigs and geological drilling rigs. Its core function is to realize the lifting and lowering of the drill pipe, transmit torque and protect the wire rope. Hollow water-through air refers to the technology of realizing the flow of liquid and gas through a hollow structure. In pile foundation construction, the down-the-hole hammer method realizes compressed air-driven hammer head to break rock formations through hollow water-through (gas-liquid composite channel). Its core design combines airflow power and fluid-assisted functions. Usually, an air compressor is used to provide 0.5-0.7MPa high-pressure air to push the impactor piston to reciprocate, generate high-frequency impact force, and cause the hammer head to cause volumetric crushing of the rock.

[0003] The existing lifter has certain disadvantages when in use. When the existing lifter is in use, an air passage is usually opened in the lifter so that compressed air drives the hammer head to crush the rock formation through the air passage. However, the compressed air frequently flows in the air passage, which increases the temperature of the lifter. Therefore, after working for a period of time, the equipment needs to be stopped, and then an external water source is injected into the air passage to cool the lifter, which reduces the efficiency of rock crushing. Moreover, when an external water source is injected into the air passage, the external water source will accelerate the corrosion of the air passage and cause scale deposition in the air passage under high temperature conditions, and will affect the sealing performance of the air passage, thereby reducing the service life of the lifter and failing to meet people's needs.

When the cleaning rod 36 moves up and down, it drives the second buffer spring 51 to move up and down in the buffer groove. The second guide rod 49, the second buffer spring 51 and the stop block 50 cooperate to make the cleaning rod 36 drive the cleaning block 48 to move back and forth, and the cleaning block 48 cleans impurities from the protective cover 33; when the external water source sprays through the drainage pipe 19, the guide seat 34 diverts the water flow and flushes the protective net block 37 and the protective cover 33, cleans impurities from the protective net block 37 and the protective cover 33, and prevents the protective net block 37 and the protective cover 33 from being blocked.

The water passage assembly also enables rapid heat dissipation from the shaft structure 3, thereby reducing the internal temperature of the lifter body 1 and extending the service life of the lifter body 1. The protective cover 33 and the protective mesh block 37 can protect the drainage pipe 19 to prevent the drainage pipe 19 from being blocked when the breaker 20 is working.
