Background technique
Hydraulic lining trolley lining cutting length range in tunnel is at 6m ~ 12m at present, and therefore net cycle time required very slow to the speed of travel about 20 hours; Road wheel is on the rail that manual work is laid, to walk; Not high to the kinematic accuracy requirement yet, and dust is big in the tunnel, and environment is more abominable; So most open kinematic chain transmission, intermittent oiling modes manually of adopting of driving mode.The impact force that starting and deboost phase chain bear in the trolley movement process is very big; Length change took place at the rear chain that works long hours because of wearing and tearing for fixing non-adjustable in the chain-driven centre distance of design in the past, an engagement ratio mutually not between chain and the sprocket wheel; Had a strong impact on the working life of chain and sprocket wheel; Be directed against former structural feature as improvement for this reason, designed a kind of eccentric adjuster, in practice, obtained good effect.
Summary of the invention
The technical problem that the utility model will solve is; A kind of hydraulic pressure tunnel lining trolley walking adjusting device for chains is provided; To overcome chain-driven centre distance that existing technology exists for fixing non-adjustable; Working long hours rear chain wearing and tearing, an engagement ratio mutually not between chain and the sprocket wheel has a strong impact on the deficiencies such as working life of chain and sprocket wheel.
The utility model adopts following technological scheme: driven sprocket is connected with follower, and follower is connected with axle through bearing, connects two eccentric bushings at the two ends of axle, and eccentric bushing is connected with walker through bolt; On eccentric bushing, be uniformly distributed with four slotted holes along the circumferential direction, the center of circle angle that slotted hole is corresponding is 25 °～35 °; 8 eccentric bushings are set on walker tapped hole is installed, it is 15～25mm with axle mounting hole eccentric distance P that eccentric bushing is installed tapped hole.
There is bearing gland at two ends at bearing.
There is thrust washer in the outside at two eccentric bushings, and thrust washer is stuck on the axle, and is fixed by bolts on the eccentric bushing.
The utility model adopts this structure of eccentric adjuster, and simple in structure, compact, easy to adjust, reliable and stable, using effect is good.

Embodiment
The embodiment of the utility model: driven sprocket 9 is connected with follower 7, and follower 7 is connected with axle 14 through bearing 11, connects two eccentric bushings 13 at the two ends of axle 14, and eccentric bushing 13 is connected with walker 8 through bolt 12; On eccentric bushing 13, be uniformly distributed with four slotted holes along the circumferential direction, the center of circle angle that slotted hole is corresponding is 25 °～35 °; 8 eccentric bushings are set on walker 8 tapped hole is installed, it is 15～25mm with axle 14 mounting hole eccentric distance P that eccentric bushing is installed tapped hole.
At the two ends of bearing 11 bearing gland 10 is arranged.
In the outside of two eccentric bushings 13 thrust washer 15 is arranged, thrust washer 15 is stuck on the axle 14, and is fixed by bolts on the eccentric bushing 13.
The center of circle angle that slotted hole is corresponding is that α is 31 °.
It is 20mm with axle 14 mounting hole eccentric distance P that eccentric bushing is installed tapped hole.
As shown in Figure 1; Motor 1 links through coupling 2 and speed reducer 3, and speed reducer 3 is connected through one-level chain 4 with driving wheel 5, and the one-level step-down ratio is i=1.3; I=1 between driving wheel 5 and the follower 7; Between driving wheel 5 and follower 7, adopt secondary chain 6 to connect, adopting the sprocket wheel chain here mainly is to increase adhesion when driving, and eccentric adjuster is arranged on the follower 7.
Eccentric adjuster is as shown in Figure 2, and two eccentric bushings, 13 cylindricals cooperate with the hole of walker 7 both sides, and circle cooperates with axle 14 in the eccentric bushing 13; The axle two ends are with thrust washer 15 location; Prevent that an axial float and circumferencial direction from rotating, thrust washer 15 is fixed by bolts on the eccentric bushing 13, has on the eccentric bushing 13 to be uniformly distributed with four elongated slots along the circumferential direction; Be used to regulate eccentric distance, sprocket wheel links to each other with road wheel with bolt.
The working principle introduction is following: the hole and the wheel shaft mounting hole eccentric distance of setting-up eccentricity cover are 20mm, and the corresponding center of circle angle in slotted hole two ends is 31 degree.
1), as shown in Figure 7, a tapped hole aligns with eccentric bushing A slotted hole on walker, this moment two centre of sprocket apart from being in the shortest position, be set at L.
2), as shown in Figure 8, when the b tapped hole aligns with eccentric bushing A slotted hole, this moment, two centre of sprocket were apart from being L+14mm.
3), as shown in Figure 9, when the d tapped hole aligns with eccentric bushing A slotted hole, this moment, two centre of sprocket were apart from being L+20mm.
4), shown in figure 10, when the e tapped hole aligns with eccentric bushing A slotted hole, this moment, two centre of sprocket were apart from being L+34mm.
5), shown in figure 11, when the f tapped hole aligns with eccentric bushing A slotted hole, this moment, two centre of sprocket were apart from being L+40mm.
From above analysis situation, two centre of sprocket in the 40mm scope, and also have ± 15.5 ° of (when α is 31 °) fine setting scopes apart from adjustable range on each diagram operating mode position, can satisfy the install adjustment requirement fully.In adjustment process, two sprocket wheel axle center short transverses also can change and since under walker and the chassis longeron to connect be the employing articulated manner, can guarantee contacting of two road wheels and rail face, can not impact trolley running and use.
