Description
Technical field
The invention belongs to mine engineering equipment technical field, it is related to one kind and is taken off for the drilling of rock-gangway bomb-dug working face, rubble
The equipment of dress, more particularly to a kind of lane space that takes is small, can improve gun diging face production efficiency, easy to operate, mobile steady
Fixed, safe and reliable caterpillar track travelling support drill loader.
Background technology
At present, many mine workings, engineering tunnel, especially section it is smaller, large shield machine or driving can not be used
The equipment such as machine implement the rock gangway of operation, and the operating type that fortune is received in main drilling, rubble is：It is artificial to use pneumatically or hydraulically rig
Working face is drilled, blown out（Explosion）After end, by supporting is manually carried out to working face with individual prop, then by after explosion
Rubble manually shovel is attached in transporter, transports working face；Lengthened after working face reaches certain length, then by transport machine equipment
To needing at blasting face.This mode needs operating personnel's hand-held drill to carry out operation in danger zone, artificial drilling, branch
Shield, shipment, and need to repeatedly carry the equipment such as rig；Mechanization, automaticity are low, and labor intensity is big, there is potential safety hazard.
Nearly all it is drill carriage and shuttle car is this kind of sets although having there is the servicing units such as some hydraulic drill rigs, roofboltier
It is standby to support the use, however it remains equipment lack roof timbering facility, hoeing material scraper bowl working range it is small, be unable to continuative transport
Material, the defect such as protective capacities is weak when blowing out, cause the limitation used larger.In addition, also have " boring dress all-in-one ", but
It is that they also all have different degrees of limitation and deficiency：It is a kind of such as " drill loader " that notification number is CN101881162B
Integrate walking, the full-hydraulic drill for shipping, drilling installation；It is crawler belt bodywork-type structure, without any supporting structure and guarantor
Protection structure, it is impossible to effective support is formed to back；When blowing out, all working part protects energy all exposed to outside
Power is weak.Moreover, the unitary design structure of this kind of shipping system and hole-drilling system is easily interfered when not only working, and
The transfer passage space of inside can not be provided；Practical effect is poor.
And notification number is CN103075152B " drill loader ", including hoeing mechanism, rock body, body frame and walking
Portion, its body frame is installed on running part, in addition to slipping mechanism, and slipping mechanism is installed on the front end of body frame；Hoeing mechanism
It is arranged on rock body on slipping mechanism, slipping mechanism can drive the both sides straight line of hoeing mechanism and rock body to body frame
It is mobile.Because its slipping mechanism is transverse moving mechanism, during real work, often there is interference shape with hoeing mechanism in rock body
Condition, has a strong impact on operating efficiency.
Therefore to the drilling of rock-gangway bomb-dug working face, the further research of rubble hoeing equipment, improve and bore dress equipment integrating pair
In the ability of roof timbering, barrier propterty of the dress equipment integrating in face firing operation process is bored in enhancing, it is to avoid Duo Zhonggong
Interfering between energy, and the ability of continuative transport material is further improved, lifting rock-gangway bomb-dug working face is bored, filled,
The mechanization of the operations such as fortune, automaticity are significant.
The content of the invention
The mechanization of the invention existed aiming at existing big gun pick mode, automaticity are low, and inefficiency, work is strong
