As Figure 20, shown in 21, the center of outer pick arm pin-and-hole 13-2-1 on the crossbeam 13-2 of casing 13 is set as 600 mm to the distance a of the center line 25 of casing 13, the thickness of fixed stop 26 is set as 25mm, the thickness b that turning block 22 clamps on the piston rod 16-2 of oil cylinder 16 outside is also set as 25mm, at II type sleeper, when sleeper pitch is the station on-line operation of 658mm, on the piston rod 16-2 of outer clamping oil cylinder 16, be fixed with 1 fixed stop 26, the lower limb degree of outside tamping pickaxe 20 is 5.6 °, now pick point is about 160mm apart from the distance of sleeper, the lower slot of outside tamping pickaxe 20 is put substantially in the middle of two sleepers, it is suitable that lower slot is put with angle, meet the instructions for use of tamping unit.
In actual use, can remove fixed stop 26, directly use turning block 22, turning block 22 can exchange with fixed stop 26.
As shown in figure 22, set a=600 mm, when tamping unit of the present invention is 695mm at II type sleeper, sleeper pitch station on-line operation, on the piston rod 16-2 of outer clamping oil cylinder 16, have 1 fixed stop 26, the lower limb degree of outside tamping pickaxe 20 is 5.6 °, and now pick point is about 140mm apart from the distance of sleeper, clamping stroke is enough, although lower slot is put near inner side, but still within zone of reasonableness, can meet the job requirements of tamping unit.
In actual use, can remove equally fixed stop 26, directly use turning block 22.
As shown in figure 23, a=600 mm, when positive on-line operation that tamping unit is 600mm at III type sleeper, sleeper pitch, on the piston rod 16-2 of outer clamping oil cylinder 16, there are 2 fixed stops 26, basic vertical lower the inserting of outside tamping pickaxe 20, lower slot is put substantially in the middle of two sleepers, and pick point is about 130mm apart from the distance of sleeper, the job position of outside tamping pickaxe 20 is good, and tamping unit operation effectiveness is good.
In actual use, can use 26,1 turning block 22 of 1 fixed stop, also can use 2 fixed stops 26.
As shown in figure 24, a=600 mm, when positive on-line operation that tamping unit is 568mm at II type sleeper, sleeper pitch, use a fixed stop 26 and a turning block 22 (also can simultaneously use 2 fixed stops 26), basic vertical lower the inserting of outside tamping pickaxe 20, pick point is about 150mm apart from the distance of sleeper, although lower slot is put near outside, but the distance of outside tamping pickaxe 20 and outside sleeper is still within zone of reasonableness, can not hit pillow phenomenon, can meet the job requirements of tamping unit.
As shown in figure 25, a=600 mm, when positive on-line operation that tamping unit is 540mm at II type sleeper, sleeper pitch, use 26 and 1 turning block 22 of 2 fixed stops, the lower limb degree of outside tamping pickaxe 20 is about-2 °, pick point is about 110mm apart from the distance of sleeper, and lower limb degree is negative angle, but angle is little; Though lower slot is put slightly near inner side, still within zone of reasonableness, can not hit pillow phenomenon with the distance of outside sleeper, therefore can meet the job requirements of tamping unit.
Adopt 22 identical schemes of thickness of fixed stop 26 and turning block, can facilitate user freely to select, generally adopt 1 ~ 3 fixed stop 26, fixed stop 26 is not fragile, and reliability is high, but needs mounting or dismounting; Turning block 22 is directly installed on outer clamping oil cylinder 16, without mounting or dismounting, but cost is high, to operating personnel require highly, need to use turning block 22 time, must make cylinder piston rod 16-2 all stretch out and just can make turning block 22 fall, otherwise may cause turning block 22 collide piston rod 16-2 and damage, in addition, cylinder 21 and turning block 22 also easily damage in dither process, and maintenance cost is high.
