Abstract
The utility model discloses a pneumatic roof bolter, which comprises a pneumatic motor, a hydraulic support, an electro-pneumatic control system, an operating arm and a rotary support. The pneumatic motor is hinged to the top end of the hydraulic support through the rotary support, and one end of the operating arm is connected to the pneumatic motor. By adding a connecting rod mechanism capable of adjusting the angle of the pneumatic motor, the pneumatic roof bolter reserves the original function of top punching while having the function of down-hole two-side punching, and meets the requirements upon the angle and the height of the pneumatic roof bolter for two-side punching, thereby increasing the utilization rate of the pneumatic roof bolter, reducing working intensity for operators, increasing working efficiency, and further the pneumatic roof bolter has the advantages of small volume, light weight, simple operation, and stable and reliable performance, and is adaptable to various underground severe environments.
Description
Technical field
The utility model relates to the rig that uses in a kind of coal industry, particularly a kind of pneumatic roof bolter.
Background technology
In coal industry, pneumatic roof bolter mainly is a kind of equipment that carries out down-hole top board drilling operation, it mainly comprises air motor, hydraulic support and associated electrical, gas control system system, air motor is fixed on the hydraulic support top, the restriction of the degree of depth and operating environment owing to punched, hydraulic support at first needs to carry out flexible accordingly, to satisfy the needs of duty, when air motor is worked, hydraulic support air motor is produced stable thrust and keep at any time stretching, follow-up, make boring procedure smoothly, finish effectively.But when needs when two help to carry out drilling operation, because two help the aperture to keep vertical with two walls, on the existing pneumatic roof bolter between air motor and the hydraulic support for fixedlying connected, for satisfy the aperture needs can only corresponding adjustment hydraulic support and ground between angle, because pneumatic roof bolter own vol and weight are bigger, punch the footpath generally all more than 2 meters, required inclination angle is bigger when making pneumatic roof bolter work, job stability and poor reliability, existing pneumatic roof bolter can't satisfy the use needs of helping in the drilling operation two basically, existing two help punching can only use the small hand-held churn to carry out, and labour intensity is big in the hand-held drill work, vibration is big, efficient is low, cost of production significantly increases.How addressing this problem, the utilization rate of improving existing pneumatic roof bolter is the problem that the utility model need solve.
Summary of the invention
In view of above-mentioned deficiency of the prior art, the utility model aims to provide a kind ofly can smoothly, effectively finish the pneumatic roof bolter that drilling operation is helped in tunnel two in the colliery.
The utility model is achieved through the following technical solutions:
A kind of pneumatic roof bolter comprises air motor, hydraulic support and electricity, gas control system system, also comprises control arm and swinging mounting, and air motor is hinged on the top of hydraulic support by swinging mounting, and control arm one end is connected on the air motor.
A kind of pneumatic roof bolter also comprises a connecting rod, and control arm is connected with air motor by connecting rod, and connecting rod is hinged with control arm and air motor respectively, and control arm is hinged on the fixed cover of hydraulic support near an end of connecting rod.
Described connecting rod comprises adapter sleeve and two studs, and an end of two studs is hinged with control arm and air motor respectively, and the other end is connected with adapter sleeve by screw thread.
A kind of pneumatic roof bolter described in the utility model, by installing the linkage that to adjust the air motor angle additional, make under the function of pneumatic roof bolter top drilling operation before keeping, had again the function of punching has been helped in down-hole two, satisfied two requirements of helping to punch to pneumatic roof bolter angle and height.Linkage angle adjustment process is simple, convenient, hydraulic support is under the situation that guarantees supporting role, also can effectively improve the propulsive force of boring, make the down-hole punching more easily, safely, reliably, both reduced the operator labour intensity, increased operating efficiency, improved the utilization rate of pneumatic roof bolter again.Machine volume is little, in light weight, simple to operate, and convenient transportation, power output are big, and stable work in work, reliable is suitable for using in the rugged environment of down-hole, can be used for also supplying water in the down-hole, in the air supply system, has stronger applicability.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Be further described below in conjunction with 1 pair of the utility model of accompanying drawing:
A kind of pneumatic roof bolter described in the utility model, comprise air motor 6, hydraulic support 2, control arm 1, swinging mounting 7, connecting rod and electricity, gas control system system, wherein, connecting rod also comprises adapter sleeve 3 and two studs 4, air motor 6 is hinged on the top of hydraulic support 2 by swinging mounting 7, one end of two studs 4 is hinged with control arm 1 and air motor 6 respectively, and the other end then is connected with adapter sleeve 3 by screw thread.Control arm 1 is hinged on the fixed cover 5 of hydraulic support 2 near an end of connecting rod, like this, formed one two linkage by control arm 1, two studs 4 and adapter sleeve 3, by operating this two linkage, reach the purpose of adjusting angle between air motor 6 and the hydraulic support 2, guaranteed hydraulic support 2 under vertical situation, air motor 6 carries out two can adjust suitable angle when helping drilling operation.Simultaneously, by rotating two studs 4, two studs 4 length in adapter sleeve 3 is changed, also can change the angle between air motor 6 and the control arm 1, under the situation that is more conducive to operate, adapter sleeve 3 and studs 4 can be locked the relative position between air motor 6 and the control arm 1.Certainly, in the time of need carrying out the top drilling operation, only need control arm 1 is adjusted to the state parallel with hydraulic support 2, this moment air motor 6 just in time vertically upward, its bottom then is supported on the fixed cover 5 of hydraulic support 2.
Claims (3)
1, a kind of pneumatic roof bolter, comprise air motor, hydraulic support and electricity, gas control system system, it is characterized in that, also comprise control arm and swinging mounting, described air motor is hinged on the top of hydraulic support by swinging mounting, and control arm one end is connected on the air motor.
