Description

A kind of mine that is used for is combined the adjustable injection support that pick flour dirt is prevented and treated
Technical field
The present invention relates to a kind of adjustable mining injection support, especially a kind of mine that is applicable to is combined the adjustable injection support of pick flour dirt control.
Background technology
To the control of fully mechanized workface dust disaster, mainly adopt external spraying, dedusting fan, ventilation dust discharge and novel foam dust-settling technology in the development machine at present.One of key point is that the depositing dust medium injection is arrived best depositing dust position in water smoke and the foam depositing dust, and dust is carried out effective shutoff, seizure and sedimentation.But because the limitation of these devices self design and processing and subsurface environment; The nozzle layout of sprinkler of water smoke and foam is often not in place with protection; Make the depositing dust medium that ejects to carry out effective shutoff, seizure and sedimentation to dust, cause anti-dust-laying effect undesirable.As; The height of spray bracket is too high runs into the top shield beam easily; Influence is to the driving of top coal petrography, and shower nozzle (mouth) coal (rock) that is prone to dropped smashes, and dust-laying effect is too poor when cutting the top coal petrography; Shower nozzle easy blocking etc. when underlying seam is tunneled in bottom has had a strong impact on the dust-laying effect of development end.
In addition, existing application is combined the injection support or the device of the control of pick flour dirt in mine, and its spray angle is basically all fixed; Can't regulate; Can only spray according to the angle of setting, jeting effect is not ideal, can't realize the effective parcel to the dirt source; To the adaptation weak effect of various driving environment, can not satisfy the dust prevention and control requirement of driving face.
In addition; The depositing dust shower nozzle generally all is installed on the head cartridge of an integral body; Because the pressure of each shower nozzle outlet of the difference of position is often different, and is big like its outlet pressure of shower nozzle near the import of depositing dust medium, little away from its outlet pressure of shower nozzle of depositing dust medium import; And for example superposed shower nozzle outlet pressure is little; And be positioned at the shower nozzle of bottom because effects such as gravity; Often outlet pressure is relatively large, so the jeting effect of each shower nozzle is difficult to reach simultaneously optimum efficiency, has also seriously influenced the effective parcel of depositing dust medium to the dirt source.
Summary of the invention
Technical problem: the objective of the invention is the deficiency to prior art, provide a kind of simple in structure, easy and simple to handle, for ease of maintenaince change, adjustable injection support that safe and reliable control mine is combined pick flour dirt.
Technical scheme: the mine that is used for of the present invention is combined the adjustable injection support that pick flour dirt is prevented and treated; Comprise gripper shoe; The clear width of gripper shoe is provided with a plurality of engaging lugs, all has on each engaging lug and the corresponding fixing hole of tunneling machine cutting head support screw, and the middle part of gripper shoe is interval with a plurality of input port through holes through input pipe; The both sides of each input port through hole all are arranged with bar hole; Be equipped with in each bar hole and add stay bolt, the front portion of each input port through hole of gripper shoe is equipped with a shower nozzle that links to each other with input pipe arm is installed, and the both sides up and down that each shower nozzle is installed arm are respectively equipped with and are sleeved on fixedly ear of the arm that adds on the stay bolt; Each adds the adjusting nut that is respectively equipped with distance between fixing and adjusting shower nozzle installation arm and the gripper shoe on the stay bolt, and shower nozzle is installed arm and is provided with a plurality of shower nozzles.
The described gripper shoe outside is provided with the baffle plate that shower nozzle is protected; Described input port through hole is a rectangular channel; Described a plurality of input ports through hole is 2-4.
Beneficial effect: control mine of the present invention is combined the adjustable injection support of pick flour dirt; Utilize depositing dust media such as water smoke, foam that high concentrate dust is administered when being applicable under the coal mine fully-mechanized digging machine cutting and crushing coal and rock; To optimize shutoff, seizure and the effect of settling of depositing dust medium, improve the utilization rate of depositing dust efficient and depositing dust medium to dust.Its shower nozzle mounting pipe is designed to shower nozzle the arm inner hollow is installed, and is connected on the gripper shoe by fixed screw, and each shower nozzle is installed the corresponding import of arm; Pressure distribution is more even with comparing before, and flow is bigger, and medium injection is more even; Disperse better effects if, can effectively wrap up the dirt source; Through the slip on input port rectangular channel and fixed screw rectangular channel, shower nozzle is installed arm and foam nozzle can radially carry out the adjusting of certain distance, and then regulates the jetting height of shower nozzle; Distance through changing between the fixed screw adjusted nut can be regulated the shower nozzle spray angle at a certain angle in all directions arbitrarily; Realize the best jeting effect of depositing dust medium through above method; Dust is carried out shutoff, seizure and sedimentation, improve depositing dust efficient.This apparatus structure is simple, and is easy for installation, and easy operating and maintain and replace are safe and reliable to operation, have practicality widely.
