Technical Field

The invention belongs to the field of transmission of shaft parts and relates to a lifting transmission device for the shaft parts.

Background

The transmission lifting device is widely applied to industries such as metallurgy, mines, coal, building materials, light industry, electric power, chemical industry and the like, and has the function of simultaneously realizing rotation and lifting of shaft parts under special working conditions.

In order to realize the function, the existing transmission lifting device has two structural forms, namely, a driving device and a shaft are rigidly and directly connected, and a motor reducer and the like must follow up when lifting; secondly, in order to avoid follow-up of transmission parts such as a motor reducer and the like, flexible transmission such as chain transmission and the like is adopted, the total length of a chain is far larger than the center distance of the main chain wheel and the auxiliary chain wheel, then the chain is tensioned by the tensioning device, and when a shaft needs to be lifted, the tensioning device needs to be disassembled, so that the lifting of the shaft cannot be synchronously carried out with the transmission.

The counter shaft of above-mentioned two kinds of structural style goes up and down, adopts traditional cylinder or pneumatic cylinder to drive: the pneumatic system is independently configured for the air cylinder by adopting the air cylinder, the lifting action is rigid, the synchronism is poor, and the stopping at any position in the lifting process cannot be realized; the traditional hydraulic cylinder is adopted, and hydraulic system elements such as a hydraulic station, a valve block and the like need to be configured.

In conclusion, the existing transmission lifting device has the defects of poor synchronism and harmony, too complex mechanism system, more fault points, poor stability, large workload of maintenance and repair, and great difficulty in production and operation.

Disclosure of Invention

In view of the above, the present invention is directed to a lifting transmission device for shaft parts. The problems that the existing transmission lifting device is poor in synchronism and cannot be synchronized in lifting and rotating are solved.

In order to achieve the purpose, the invention provides the following technical scheme:

a lifting transmission device for shaft parts comprises a first bearing seat, a driving module and a first lever module; the first bearing seat is used for supporting shaft parts; the driving module is used for driving shaft parts to rotate and comprises a driving motor, a driving wheel driven by the driving motor to directly rotate, a driven wheel coaxially arranged with the bearing seat and a transmission belt used for connecting the driving wheel and the driven wheel; the first lever module comprises a lever arm, an electro-hydraulic direct-drive cylinder and a hinged support; the hinged support is fixedly arranged, one end of the lever arm is hinged to the hinged support, and the other end of the lever arm directly drives the lever arm to swing around a hinged point through the electro-hydraulic direct drive cylinder.

Optionally, the driving wheel and the driven wheel are both arranged on the lever arm.

Optionally, the first lever module further comprises a second bearing seat arranged in a mirror image with the first bearing seat and the first lever module.

Optionally, a speed reducer is arranged between the driving motor and the driving wheel.

Optionally, the driving motor and the driving wheel are fixedly arranged, and the positions of the driving motor and the driving wheel are not changed along with the action of shaft parts driven by the electro-hydraulic direct-drive cylinder.

Optionally, the hinge support is arranged on the fixed support.

Optionally, the fixed support is provided with a lifting mechanical stop for fixing the lever arm.

Optionally, a via hole is formed in the lever arm, and the lifting mechanical stop is matched with the arrangement position of the via hole.

The invention has the beneficial effects that:

two bearing blocks of the invention are arranged on two lever arms with the same length and swing fulcrum, and the lever arms swing up and down around the fulcrum to realize the lifting of shaft parts; the fulcrum of the lever arm and the axis of the driving wheel driven in rotation are on the same axis, so that when the lever arm drives the shaft parts to lift, the central distance between the driving wheel and the driven wheel is always kept unchanged, and the restriction of the shaft parts on lifting is not brought.

Referring to fig. 1-4, the reference numbers in the figures refer to the following elements: the device comprises a driving motor 1, a speed reducer 2, a driven wheel 3, a lever arm 4, an electro-hydraulic direct-drive cylinder 5, a shaft part 6, a fixed support 7, a lifting mechanical stop 8, a bearing seat 9, a transmission chain 10 (a transmission belt), a driving wheel 11, a fulcrum hinged support 12 and a hinged support 13.

In the use process of the invention, the left end and the right end of a shaft part 6 which needs to be driven to rotate and lift simultaneously are supported by bearing blocks 9 to rotate, and a driven wheel 3 is arranged outside a first bearing block and is a driving end. The first bearing seat and the second bearing seat are respectively arranged on a left lever arm 4, a right lever arm 4, the length of which is the same as that of a fulcrum, an input shaft of the driving motor 1 is directly connected with an input shaft of the speed reducer 2, an output shaft of the driving wheel 11 is directly connected with an output shaft of the speed reducer 2, the driving wheel 11 and the driven wheel 3 transmit the driving force for driving the rotation of the shaft type parts 6 through the transmission chain 10, the driving motor 1, the speed reducer, the driving wheel 11, the transmission chain 10 and the driven wheel 3 form a transmission device for driving the rotation of the shaft type parts 6, and the driving motor 1 and the speed reducer are fixed.

The output shaft of the speed reducer, the driving wheel 11 and the pivot hinged support 12 are arranged on the same horizontal axis, and the pivot hinged support 12 is arranged on the fixed support 7 through a hinged support 13. The lever arm 4 is driven by the electro-hydraulic direct drive cylinder 5 to swing up and down around the axis of the fulcrum hinged support 12. The piston rod of the electro-hydraulic direct drive cylinder 5 extends out, the lever arm swings upwards, and the position of the corresponding shaft part 6 rises; the piston rod of the electro-hydraulic direct drive cylinder 5 retracts, the lever arm 4 swings downwards, and the position of the corresponding shaft part 6 descends. Because the axial lines of the pivot hinged support 12 and the driving wheel 11 are the same straight line, the axial distance between the driving wheel 11 and the driven wheel 3 is not changed when the lever arm 4 swings up and down (the shaft parts 6 ascend and descend), namely the swinging radiuses are equal at any position, the transmission of the shaft parts 6 does not restrict the ascending and descending, and the shaft parts 6 can still rotate while ascending and descending.

The electro-hydraulic direct-drive hydraulic station and the intermediate piping are not needed, civil construction is not needed, the whole transmission mechanism system is simple, fault points are few, and the workload of maintenance is small. The lifting synchronism, coordination and stability of the shaft parts 6 are good due to the rigid lever arm swing structure form and the electro-hydraulic direct-driven lifting driving form; the lifting mechanical stop 8 is arranged on the lever arm 4, when the shaft part 6 is required to stay at any position in the lifting process, the adjusting bolt screwed out of the lifting mechanical stop 8 is in rigid contact with the fixed support 7, the shaft part 6 can hover at any position in the lifting overweight process, and the electro-hydraulic direct drive cylinder 5 does not need to exert force at the moment.

The invention adopts the electro-hydraulic direct drive cylinder 5 as a lifting power source, and the electro-hydraulic direct drive cylinder 5 is a highly integrated electromechanical integrated product, so that the device has the characteristics of heavy load, large output, high precision, high response, intellectualization, system simplification and maintenance-free, and solves the problems of poor lifting driving synchronism, harmony and stability of the shaft of the traditional transmission lifting device, excessively complex mechanism system, high energy consumption, multiple fault points and large overhauling and maintenance workload.
