Compared with prior art, the utility model has the beneficial effects that by increasing the first adjustment bolt group, the first locking Above and below cap group, second adjustment bolt group, the second locking cap group, limit spring group, control brake disc and clutch friction disk Position, it is ensured that brake friction pair does not contact clutch friction pair when disengaging with clutch and do not contact when braking disengages, to guarantee vertical The air disc clutch of installation operates normally in tubbing equipment.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:

As seen from Figure 1, the utility model includes: clutch body；The clutch body include: clutch base 1, from Close cylinder 2, clutch piston 3, tripping spring group 4, the first sealing ring 5, the second sealing ring 6, the first screw group 9；The clutch The rotation axis connection of device seat 1 and tubbing equipment；The clutch air cylinder 2 is fixed on clutch base 1 by the first screw group 9； The clutch piston 3 is mounted between clutch base 1 and clutch air cylinder 2, and forms air cavity；First sealing ring, 5 He Second sealing ring 6 is separately mounted on clutch piston 3, for the compressed air in sealed air-space；The tripping spring group 4 is pacified Between clutch piston 3 and clutch base 1, for clutch piston 3 reset and realize braking function；Further include: braking rubs Wiping group；The drag friction group includes: brake disc 8, coupling sleeve group 12, the second screw group 13, the first adjustment bolt group 15, the first locking cap group 16；The brake disc 8 is mounted between clutch air cylinder 2 and clutch piston 3；The drag friction Disk 8 and clutch air cylinder 2, clutch piston 3 form brake friction pair, and when engagement transmits braking moment；The coupling sleeve group 12 is logical It crosses the second screw group 13 to connect with the rack 18 of braking equipment, which is set in the hole group of brake disc 8, braking Frictional disk 8 is driven braking torque by coupling sleeve group 12 and coupling sleeve group 12 can move axially relatively；The first adjustment spiral shell Bolt group 15 is fixed in the rack 18 of tubbing equipment, and the first adjustment bolt group 15 is used to limit the downward actuation of brake disc 8, First locking cap group 16 is for locking 15 groups of the first adjustment bolt；By adjusting the first adjustment bolt group 15, drag friction is controlled The upper and lower position of disk 8 guarantees that brake disc 8 is not contacted with clutch cylinder body 2 and clutch piston 3 when braking disengagement；Further include Clutch friction group；The clutch friction group includes: clutch friction disk 7, limit spring group 14, second adjustment bolt group 10, Two locking cap groups 11；The clutch friction disk 7 is mounted between clutch base 1 and clutch piston 3, clutch friction disk 7 with from Clutch seat 1, clutch piston 3 form clutch friction pair, and when engagement transmits clutch torque；The limit spring group 14 is mounted on system In 17 hole of rotating wheel of bucket equipment, limit spring group 14 supports clutch friction disk 7 to be self-possessed；The second adjustment bolt group 10 is solid Be scheduled in the rotating wheel 17 of tubbing equipment, second adjustment bolt group 10 for limit because the spring force of limit spring group 14 push from The upward movement of frictional disk 7 is closed, the second locking cap group 11 is for locking second adjustment bolt group 10；By adjusting second adjustment spiral shell Bolt group 10 controls the upper and lower position of clutch friction disk 7, guarantee when clutch disengages clutch friction disk 10 and clutch base 1 and from Piston 3 is closed not contact.

The working principle of the utility model is: entering from external compressed air by 3 shape of clutch air cylinder 2 and clutch piston At air cavity, clutch piston 3 compress tripping spring group 4 move down, clutch friction pair engagement, brake friction pair disengage, clutch Device ontology is rotated with the rotating wheel 17 of tubbing equipment.Because brake disc 8 is self-possessed, brake disc 8 moves down trend, adjusts Whole the first adjustment bolt group 15 controls drag friction auxiliary air gap, so that it is guaranteed that clutch body rotates Shi Buyu brake disc 8 Generate interference.When compressed air is discharged from the air cavity that clutch air cylinder 2 and clutch piston 3 are formed, clutch piston 3 is in tripping spring It is moved up under 4 effect of group, brake friction pair engagement, clutch friction pair disengages, and clutch body is quiet with the rack of tubbing equipment Only.Because of the self weight of clutch friction disk 7, clutch friction disk moves down trend, therefore in clutch friction disk 7 and tubbing equipment Limit spring group 14 is set between rotating wheel, and limit spring group 14 bears the self weight of clutch friction disk 7.Due to limit spring group 14 Spring force can be greater than clutch friction disk 7 self weight, so that clutch friction disk 7 is moved up trend under spring force, lead to Cross adjustment second adjustment bolt group 10, control clutch friction auxiliary air gap, so that it is guaranteed that with braking equipment rotating wheel 17 rotate from It closes frictional disk 7 and does not generate interference with clutch body.
