Description
Technical field
The utility model is an a kind of pair of turntable bearing formula swing type mechanism, belongs to the hoisting crane field, particularly the turning gear of locomotive crane.
Background technology
At present, for telescopic boom and have the locomotive crane of telescopic counterbalanced weight, the flexible stroke of its counterbalanced weight is generally longer.The counterbalanced weight tail radius that stretches out when big revolution operation is excessive, just very easily causes that counterbalanced weight conflicts with cutting slope, or influences adjacent lines and normally use or cause use and safety problem such as topple backward.The bottleneck that these problems become telescopic counterbalanced weight locomotive crane development and promote presses for a kind of hoisting crane that can solve this bottleneck problem of exploitation for this reason.
The utility model content
The purpose of this utility model provides a kind of two turntable bearing formula swing type mechanisms that are used for locomotive crane, unbalance during with the big revolution operation of effective solution locomotive crane topples and counterbalanced weight stretches out back tail radius problems of too, makes that locomotive crane is not only simple to operate, lifting performance is good and safe and reliable.
The technical scheme that the utility model is realized is as follows:
The utility model comprises the heavy-duty machine arm, operator's compartment, last turntable, following turntable, the counterbalanced weight telescopic boom, counterbalanced weight, last swing type mechanism, turning down mechanism, last rotary reducer, turning down retarder and corresponding power hydraulic system, arm, operator's compartment is installed on the turntable, the counterbalanced weight telescopic boom, counterbalanced weight is installed in down turntable, characteristics are to go up swing type mechanism to be made up of last pivoting support and last rotary reducer, turning down mechanism is made up of turning down supporting and turning down retarder, the inner ring of last pivoting support is installed in the lower surface of turntable collar tie beam through Bolt Connection, last revolution supporting outer ring connects the collar tie beam upper surface that is installed in down turntable through double-screw bolt, and the inner ring of last pivoting support and two last rotary reducers are through gear mesh; Turning down supporting inner ring is installed in down the lower surface of turntable collar tie beam with Bolt Connection, the turning down supporting outer ring through Bolt Connection be installed in get off on, the outer ring of turning down supporting and turning down retarder are by gear mesh, upper and lower rotary reducer is installed in down the collar tie beam corresponding site of turntable respectively through Bolt Connection, the revolution axle center of upper and lower swing type mechanism and the revolution axis coinciding of upper and lower turntable, and pass the longitudinal axis of getting off, be separately installed with Locking Device at last turntable and following turntable, following turntable and between getting off.
Use hoisting crane of the present utility model and can do full circle swinging operation and suitable rail direction ± 30 ° of operations.When carrying out the full circle swinging operation, Locking Device locking between last turntable and following turntable, following turntable and get off between Locking Device open; When being used as along rail direction ± 30 ° of operations, Locking Device is opened between last turntable and following turntable, following turntable and get off between Locking Device lock; When hoisting crane travelled non-hoisting operation on the iron network, two Locking Devices all were in lockup state, thereby the longitudinal axis of getting on the bus is kept along the rail direction running.
When 1, the utility model was applied to locomotive crane full circle swinging operation, the locking of Locking Device between the upper and lower turntable was opened with the Locking Device between getting off at turntable down, this moment the utility model except that the outer ring that turning down is supported all with the relative locking of getting on the bus.The gear 16 that is driven turning down retarder 5 by HM Hydraulic Motor 15 rotates, because of the outer ring engagement of gear 16 with turning down supporting 12, and turning down is supported 12 outer rings and is fixed on and gets off on 9, then turning down retarder 5 supports the torque drive rotary reducer 5 wraparound rotating shaft hearts 10 rotations of the counter-force formation of 12 outer rings generation with turning down, and drives the whole rotation of getting on the bus that connects firmly with it.
2, the utility model is applied to locomotive crane along in the rail direction ± 30 ° scope during revolution operations, the Locking Device 20 between the turntable is up and down opened, and will play turntable and get off between Locking Device 19 locking, at this moment, last turntable 4 and last pivoting support 3 affixed can rotations jointly, other each several parts lock static mutually.Driven by HM Hydraulic Motor 17 two going up rotary reducer 11 drives the inner ring wraparound rotating shaft heart 10 rotations of going up pivoting support 3 and drives affixed last turntable 4 through gear 14 and make gyroscopic movement, its revolution range can be in ± 30 °, arm 1, operator's compartment 2 are installed on the turntable 4, so hoisting crane can be realized along rail ± 30 ° of revolution operations that scope is interior.Because following turntable 6 does not rotate so be installed in down the fore and aft motion of the counterbalanced weight on the turntable 6 when guaranteeing the hoisting crane lifting performance, be included in the safety in utilization that has guaranteed hoisting crane within the vehicle gauge of the locomotive all the time simultaneously.
The two turntable bearing formula swing type mechanisms of the utility model are made up of two cover revolution supportings and fluid pressure drive device up and down, are used to have the locomotive crane of pair turntables, rational in infrastructure, simple to operate, can make the hoisting crane lifting performance good, safe and reliable, be applicable to the needs of present stage locomotive crane operation.When the telescopic boom locomotive crane that has a telescopic counterbalanced weight carries out hoisting operation on railway, arm, last turntable can turn round operation along in the rail direction certain angle scope, can do 360 ° synchronous revolution in conjunction with following turntable again, and make hoisting crane the flexible of counterbalanced weight under two kinds of operation situations can satisfy the lifting demand, can avoid its radius of turn excessive and influence operation again, even cause safety to have problems.
