Description

Bale panoramic tables

Technical field:

The apparatus for rotating that uses when the utility model relates to a kind of the casting specifically is a kind of bale panoramic tables that waters the steel position that returns back to steel ladle.

Background technology:

In the continuous casting workshop of each steel mill, generally all to use bale panoramic tables and support the transhipment steel ladle, the rotation through bale panoramic tables forwards the steel ladle that fills with molten steel to and waters the steel position; Forward the sky bag that pours to simultaneously and receive package location, at present, like Fig. 4 and shown in Figure 5; Bale panoramic tables generally comprises panoramic table base 1, panoramic table 4, gear pivoting support, brake gear 16 and be installed in the motor 15 and reductor 2 on the panoramic table base, and the output shaft of motor 15 is connected with the power shaft of reductor 2; Brake gear 16 is between motor 15 and reductor 2, and the gear pivoting support comprises inner ring 5 and external tooth wheel rim 7, is provided with steel ball 6 between inner ring 5 and the external tooth wheel rim 7; Inner ring 5 is connected with panoramic table base 1, and external tooth wheel rim 7 is connected with panoramic table 4, is connected with pinion 3 on the output shaft of reductor 2;

Pinion

3 and 7 engagements of external tooth wheel rim, during work, rotate motor 15 energising backs; Thereby through drive the rotation of panoramic table 4 after the deceleration of reductor 2 again through the pinion 3 and the engagement of external tooth wheel rim 7; When returning back to steel ladle when watering the steel position, motor 15 outages start brake gear 16 simultaneously; Brake through brake gear 16 stops operating motor 15; Thereby steel ladle on the panoramic table 4 is navigated to water the steel position, at this moment panoramic table 4 static is to realize through the engagement with external tooth wheel rim 7 of the gear meshing in the reductor 2 and pinion 3, can produce vibrations when steel ladle winches to or hang panoramic table 4 last time panoramic table 4; Vibrations tend to cause the rotation of panoramic table 4; And the engagement meeting of pinion and external tooth wheel rim 7 is delivered to the rotatory force that the rotation of panoramic table 4 produces in the reductor 2, and one proper to be in braking state be inactive state and this moment, reductor 2 was connected with motor 15, thereby make this rotatory force cause certain damage to reductor 2.

The utility model content:

The technical problem that the utility model will solve is to provide a kind of when steel ladle winches to or hang on the panoramic table, the bale panoramic tables that can the reductor damage encircled because of the vibrations of panoramic table generation.

The technical solution of the utility model is; A kind of bale panoramic tables with following structure is provided: comprise panoramic table base, panoramic table, gear pivoting support, be installed in motor, reductor and brake gear on the panoramic table base, the output shaft of motor is connected with the power shaft of reductor, and brake gear is between motor and reductor; The gear pivoting support comprises inner ring and external tooth wheel rim; Be provided with steel ball between inner ring and the external tooth wheel rim, inner ring is connected with the panoramic table base, and the external tooth wheel rim is connected with panoramic table; Be connected with pinion on the output shaft of reductor; Pinion and the engagement of external tooth wheel rim, wherein, the panoramic table base is provided with a plurality of hydraulic locking mechanisms that are used to lock panoramic table.

The described bale panoramic tables of the utility model, wherein, hydraulic locking mechanism comprises hydraulic cylinder bearing, hydraulic cylinder, connecting rod, locking device bearing and latch segment; Cylinder body one end and the hydraulic cylinder bearing of hydraulic cylinder are hinged; Piston rod one end of hydraulic cylinder and the lower end of connecting rod are hinged, and the middle and upper part of connecting rod and locking device bearing are hinged, and the upper end and the latch segment of connecting rod are hinged; Locking device bearing top braces latch segment; The latch segment left end is near panoramic table, and the hydraulic cylinder bearing is connected with the panoramic table base through hydraulic cylinder base, and the locking device bearing is connected with the panoramic table base through the locking device base.

After adopting above structure, compared with prior art, the utility model bale panoramic tables has the following advantages: when driven by motor panoramic table rotation returns back to steel ladle when watering the steel position; Motor outage starts brake gear simultaneously, and the brake through brake gear stops operating motor; At this moment through hydraulic oil hydraulic cylinder is controlled, hydraulic cylinder is strutted, at this moment the piston rod on the hydraulic cylinder can promote the connecting rod rotation; The hinged latch segment of small end is moved to the left, is pressed on the panoramic table, thereby locks panoramic table; When panoramic table produces vibrations, because panoramic table is in locking state, the rotation that therefore can not produce panoramic table; Increase the stability of panoramic table, thereby can not decrease ring speed reducer.
