A kind of pneumatic track borer, as shown in Figure 3,4, including borer body frame 3, described borer body frame 3 left part arranges right baffle-plate 24, described right baffle-plate 24 arranges screw 20 and installs feed screw 2；Described borer body frame 3 installs air motor seat 4 by two side slideways 26, and slideway pressing plate 6 is installed in described air motor seat 4 both sides.Feed screw 2 drives air motor seat 4 along slideway 26 side-to-side movement.
As shown in Figure 3,4, described feed screw 2 right-hand member is connected on the left of air motor seat 4 by thrust bearing 23；Air motor 21 is installed in described air motor seat 4, motor selects that volume is little, the slow-speed of revolution, large-torque pneumatic motor；The shaft head of described air motor 21 passes on the right side of air motor seat 4 and fixedly mounts trepanning drill coupling sleeve 7 by bonded mode, and described trepanning drill coupling sleeve 7 installs hollow alloy tool steel bit 22 by jackscrew 27；Installing material returned compression spring 8 and material returned push rod 10 in described trepanning drill coupling sleeve 7, described material returned push rod 10 penetrates hollow alloy tool steel bit 22.After having holed, utilizing the restoring force of spring, push rod is for ejecting the waste material in hollow boring bit, and meanwhile, hollow boring bit is also ejected coupling sleeve, exits drill bit smoothly.
As shown in Figure 3,4, described borer body frame 3 right part arranges right baffle plate 25, described right baffle plate 25 fixedly mounts the quiet locating module of track 12, and right baffle plate 25 and the quiet locating module of track 12 are by centring ring 9 location and installation.For track different size, quiet locating module can select three kinds of models such as 22kg, 30kg, 38kg.
As shown in Figure 3,4, described hollow alloy tool steel bit 22 is through right baffle plate 25 and the quiet locating module of track 12.
As shown in Figure 3,4, limiting plate 11 is installed on described right baffle plate 25 top, for limiting the excessive rotation of clamping support 13.
Positioned as in figure 2 it is shown, described borer body frame 3 right-hand member connects clamping support 13, described borer body frame 3 and clamping support 13 by clamping support rotating shaft 14 by clamping support latch 15；Described clamping support 13 end face threadedly installs clamping screw 18, and described clamping screw 18 left end is installed track by thrust bearing 23 and moved compact heap 16.Fixedly mounting compact heap guide post 17 on described clamping support 13, described track moves compact heap 16 and moves along compact heap guide post 17.Track both sides arrange the web of the rail portion form fit of dynamic compact heap and quiet locating module, static determinacy position modular shape and track, on the left of track, dynamic compression module is promoted on the right side of compression track, and, dynamic pressure tight module pressing face hollow, enter after drilling through track riser for drill bit.
As shown in Figure 3,4, described feed screw 2 left end installs handle head 1；Described clamping screw 18 right-hand member installs handlebar 19.
Operation principle and the use step of the said goods are as follows:
Source of the gas connected by air motor, pneumatic control case control, and control chamber is equipped with moisture trap, Pressure gauge, oil sprayer, manipulation valve.
The first step: rotate counterclockwise into screw mandrel 2, promote dotted line position in air motor seat 4 to Fig. 1.
Second step: in motor drive shaft head position by bonded fix trepanning drill coupling sleeve 7, trepanning coupling sleeve 7 in pass through jackscrew fixation hollow alloy rail drill bit 22.
3rd step: more finish changing track locating module 12 according to track model, put down dotted line position in clamping support 13(schematic diagram 1 and be put into operating position), loading clamping support latch 15, coincide inside and outside locating module 12, compact heap 16 and track 28 riser, clamping screw 18 to the fastening that turns clockwise puts in place.
4th step: the feed screw 2 that turns clockwise contacts to hollow alloy rail drill bit 22 substantially with track 28 riser.
5th step: control valve is beaten behind the position opened, air motor 21 drives hollow alloy rail drill bit 22 to rotate, slowly turn clockwise feed screw 2, motor base 4 is promoted to move ahead, after hollow alloy rail drill bit contacts with track riser, according to hollow rail bit cutting situation, turn clockwise feed screw 2, until drilling through the web of the rail riser of track, and then counter clockwise direction swivel feeding leading screw 2, motor base 4 is driven to exit drill bit, closing source of the gas, motor stops operating, and unclamps clamping device, (mentioning dotted line position) exits track, and boring completes.
The major advantage of this air motor borer is as follows:
1, work safety, there is explosion-proof performance, do not affected by high temperature and vibration simultaneously.
2, work can be fully loaded with for a long time, and temperature rise is less.
3, power bracket and the range of speeds are the widest.
4, there is wider detent torque, startup can be carried by band.
5, volume is little, compact conformation, handiness, and maintenance is easy, low cost.
6, efficiency is high, and source of the gas is convenient, is the ideal tools of coal mine upper and lower track boring.
The using method of above-mentioned air motor borer is as follows with points for attention:
A, air motor borer preoperation inspection
1, each portion part the most complete, fastening, slideway oiling, feed screw and clamping screw oiling.
2, check whether track locating module is consistent with track.
3, test running after pipeline connects, confirms that direction of rotation is the most correct.
B, motor use condition
1, power is used: compressed air.
2, maximum working pressure: 7kg/cm2, normally use pressure: 7kg/cm2。
3, environment temperature :-10 DEG C ~+70 DEG C just can use under (freezing) state that do not freezes.
4, lubricating oil: pneumatic vane motor air intake, through oil syringe oil supply, uses ISOVG32 low-viscosity oil, and 1-2 per minute drips.
C, operating specification
1, use gas must add the process of source of the gas three linked piece and just can enter air motor (moisture trap, Pressure gauge, oil sprayer).
2, there is load to use continuously, zero load can not use continuously.
It should be noted last that; above example is only in order to illustrate technical scheme and unrestricted; although being described in detail with reference to the embodiment of the present invention; it will be understood by those within the art that; technical scheme is modified or equivalent; without departure from the spirit and scope of technical scheme, it all should be contained in the claims of the present invention.
