Hole drilling tooling

Abstract

The invention relates to a hole drilling tooling, which is characterized by comprising an installing seat, a motor output shaft, a connecting seat, a first oil cylinder, a connecting bearing, an oil opening, a second oil cylinder, a protection sleeve and a drill bit, wherein the device comprises a support device, a power mechanism and a feeding device; the support device is the installing seat; the motor output shaft is arranged on the installing seat in a sleeving way; one side of the motor output shaft is connected with a protection sleeve of the feeding device through a sliding connecting seat; the protection sleeve is made of high-hardness steel; the first oil cylinder and the second oil cylinder are arranged in the protection sleeve; the connecting bearing is arranged between the first oil cylinder and the second oil cylinder; the lower side of the connecting bearing is provided with the oil opening; and the front end of a telescopic rod of the second oil cylinder is in transmission connection with the drill bit arranged at the front of a sleeve. The hole drilling tooling has the advantages that the structure is ingenious; the production is safe; the positioning hole drilling is realized; the hole drilling tooling is applicable to continuously changed operation environment; the adaptive capacity is high; the applicability is high; the economic benefits are good; parts are made of high-hardness steel; the protection effect is good; the service life of the device is long; the complete mechanization of moving, ascending and descending is realized; the automation degree is high; and the modern production requirements are met.

Description

technical field [0001] The invention belongs to the field of mechanical devices, in particular relates to drilling equipment in coal mines, and particularly provides a drilling tool. Background technique [0002] At present, in the coal mine industry, the safety requirements are getting higher and higher. Anti-burst holes and anchor holes play an important role in safe production. The anti-burst holes and anchor holes are distributed on the tunnel arm. There are many. Now the anti-burst and anchor holes are The holes are all drilled through the pneumatic auxiliary machine and the anti-outburst drilling machine, but when using this kind of equipment, the workers directly hold the drilling machine to drill directly, which has great potential safety hazards, and there are often accidents that hurt people because they cannot hold it. And the operating environment is constantly changing, the use of the drilling rig is also very inconvenient, the labor intensity of personnel is la...
