Maintenance of drilling equipment of saddle iron zq-51 nylon sleeve drilling machine

  Saddle iron zq-51 nylon sleeve drilling machine drilling equipment maintenance life will not treat us well from time to time, there will always be setbacks and failures
We should learn to face it calmly with a philosophical attitude towards life and meet it with a peaceful and indifferent state of mind
When we regard these as a valuable asset in our life, the sky of our hearts will not always be cloudy

Maintenance of drilling equipment of saddle iron zq-51 nylon sleeve drilling machine
Zq-51 nylon sleeve drilling machine is mainly used for the anchor pulling operation during the replacement of railway concrete sleeper bolts, and is mainly used for the anchor pulling operation during the replacement of railway concrete sleeper bolts

Technical parameters:
1
Gasoline engine power: 1
47kw/7000rpm

2
Drilling diameter range: φ 38mm-φ 51 mm。
3
Spindle speed: 1000 rpm

4
Reaming slope: 3:20

5
Overall mass: 43kg

Operating procedures:
1
Install &phi according to the needs of field work; 31 hollow bit or & phi; 13
5、φ 9
8 twist drill
Specific methods:
　　φ The installation of 31 hollow drill bit is to loosen the set screw at the main shaft sleeve, insert the drill bit into the sleeve, and then tighten the set screw to complete the installation

　　Φ 13
5 or φ 9
8 the installation of twist drill is to insert the attached bit seat (the bit seat can be configured with different specifications and clamp twist drill according to the needs of users) into the sleeve after loosening the set screw at the spindle sleeve, then insert the twist drill into the bit seat, and then tighten the set screw to complete the installation of twist drill

2
Select the positioning block 10 with the same model as the drilled rail (this positioning block is a combined dual-purpose positioning block, the number 50 represents 50kg / m rail, the surface with the number shall be installed on the side close to the rail, and other rail types, etc
) and install it on the front plate

3
Check whether the fuel quantity of gasoline engine is sufficient
If it is insufficient, add fuel first
Refer to the instructions of gasoline engine for specific methods (gasoline and special lubricating oil are used for four stroke gasoline engine)

4
Place the water injection bucket 11 with coolant on the same side of the whole machine, and insert the cooling water pipe 13 into the water inlet nozzle 3

5
Inspection before operation: start gasoline engine 1, idle for one minute, check whether the transmission part is flexible, whether there is abnormal noise, whether the threaded connection is loose, whether the cooling is smooth, etc

6
Lift the clamping handle 6 to open the rail clamping mechanism, place it on the steel rail, adjust the adjusting nut 7 of the rail clamping mechanism until the steel rail can be firmly clamped when pressing the clamping handle (generally, the two tips at the lower part of clamp 8 are clamped at about the rail waist), loosen it and go down freely to ensure that the center of the steel rail to be drilled is consistent with the center of the drill bit (drill with a positioning ruler, see 10 for details), Moreover, the front plate is visually perpendicular to the rail bottom, the positioning block is in arc sensitive contact with the rail palate and rail bottom, and then press down and clamp the handle 6
After the clamping is firm, the drilling operation can be carried out

7
Before drilling, inflate the water injection bucket 11 (generally about 10 times), open the water valve 12, and then start the gasoline engine
When all parts work normally, pull the feed handle 9 to carry out the drilling operation
When the top contacts the steel rail, the coolant will flow out automatically to cool the drill bit

8
When drilling, the force shall be applied evenly and not too hard
When drilling through, the feed speed shall be slowed down

9
After drilling, operate the feed handle 9 to return the drill bit and turn off the gasoline engine
Then close the water valve 12, take away the water injection bucket, lift the clamping handle 6, loosen the clamping rail mechanism, move the drilling machine to another drilling position, and carry out drilling operation or lower the whole machine according to the same method

10
The positioning ruler 5 of the machine has the function of drilling positioning, that is, put the drilling machine on the steel rail, press down the clamping handle 6, pull out the ruler locator 4, and insert the positioning ruler 5 corresponding to the type of drilled rail (the positioning ruler mark 50 represents 50kg / m steel rail, and so on) from the sleeve hole of clamp 8, The ruler locator 4 can position the positioning ruler 5 corresponding to different hole positions of the fishplate (the first groove at the stop end of the positioning ruler is the positioning point from the first hole on the end face of the rail, and so on)
Make the positioning ruler stop close to the rail end, press down the clamping handle 6, and then the drilling operation can be carried out
Note: before clamping the rail, the positioning block stop must be close to the rail end face to ensure accurate drilling positioning
