Technical field

The utility model relates to and the matching used attached tooling device of fork truck.

Background technology

In industries such as food, automated production, chemical industry, article recovery, metallurgy and foundries, under some operating mode, need be rotated article, hopper or chest and tumble and stir, the general employing of factory is built complex apparatus and device voluntarily or is used manual type to satisfy top special operation condition, build complex apparatus and device or use manual type all can cause plant produced efficient low, equipment utilization is insufficient, the problem that productive costs is high.If use attach troops to a unit tool then can solve above problem of fork truck, but existing all kinds of lift truck attachments also all can not finely satisfy above applying working condition.

Summary of the invention

Satisfy factory's needs and be rotated and tumble and the problem of special applying working condition such as stirring in order to solve the mobile alerting ability that utilizes fork truck and the cheap advantage of use cost, the utility model provides a kind of lift truck attachment spinner.

Concrete technical solution

The lift truck attachment spinner comprises noseplate, back base plate, swing type mechanism and speed reduction gearing;

Described noseplate and back base plate are parallel to each other;

Described swing type mechanism comprises pivoting support inner ring, pivoting support outer ring and the steel ball between the two; The pivoting support inner ring is fixed on the noseplate, and its inner peripheral surface is an internally toothed annulus; The pivoting support outer ring is fixed on the base plate of back; Be laid with steel ball between pivoting support inner ring and the pivoting support outer ring, constitute swing bearing;

Described speed reduction gearing comprises worm gear and worm screw, worm gear is located at back base plate upper outside face by worm-wheel shaft, the other end of worm-wheel shaft is provided with miniature gears, miniature gears is between noseplate and back base plate, and the internally toothed annulus engagement with the pivoting support inner ring drives the rotation that internally toothed annulus is realized noseplate by miniature gears; Worm screw is positioned at the bottom of worm gear, and the input end of worm screw is connecting hydraulic motor output shaft; The oil inlet of HM Hydraulic Motor and oil outlet are being connected the oil inlet and the oil outlet of bidirectional hydraulic lock respectively;

Back base plate upper outside face both sides are separately installed with hook, and lateral surface both sides, back base plate bottom are separately installed with lower draw-bar.

Described worm gear passes through the bearing fixing of worm-wheel shaft both sides in reducer shell, and the worm screw that cooperates with worm gear is fixed in the reducer shell by the worm bearing at two ends, and reducer shell is fixed on the base plate of back.

Described hydraulic motor output shaft is connected with worm screw by spline.

The utlity model has the advantage of the following aspects:

1, noseplate of the present utility model can install multiple equipment additional, cooperates fork truck easy to use, flexible, and Applicable scope is extensive.

2, owing to adopt worm and gear and pivoting support, make this product with compact structure as speed reduction gearing, rationally distributed, from heavy and light.

3, the very big of back output torque change because employing low rotation speed large torque HM Hydraulic Motor and process two-stage big retarding ratio slow down.

4, because the HM Hydraulic Motor that adopts can positive and negative 360 ° of rotations, cooperate the function of bidirectional hydraulic lock again, noseplate all can two-wayly be locked at an arbitrary position.

5, this product is connected with fork truck by upper and lower hook, and is simple and reliable for structure, easy accessibility.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Embodiment:

Referring to Fig. 1 and Fig. 2, the lift truck attachment spinner comprises noseplate 6, back base plate 8, swing type mechanism and speed reduction gearing.Noseplate 6 and back base plate 8 are parallel to each other, and see Fig. 2; Swing type mechanism comprises pivoting support inner ring 5, pivoting support outer ring 7 and the steel ball between the two 9; Pivoting support inner ring 5 is installed on the noseplate 6 by bolt, and its inner peripheral surface is an internally toothed annulus; Pivoting support outer ring 7 is installed on the base plate 8 of back by bolt; The uniform steel ball 9 that is equipped with between pivoting support inner ring 5 and the pivoting support outer ring 7 constitutes swing bearing;

Speed reduction gearing comprises worm gear 3, worm screw 2 and HM Hydraulic Motor 1, the bearing fixing of worm gear 3 by worm-wheel shaft and both sides is in reducer shell 13, reducer shell 13 is fixed in back base plate 8 upper outside faces, worm screw 2 is fixed in the reducer shell 13 by the worm bearing at two ends, and be positioned at the bottom of worm gear 3, miniature gears 4 is installed on the other end of worm-wheel shaft, miniature gears 4 is between noseplate 6 and back base plate 8, and the internally toothed annulus engagement with pivoting support inner ring 5 drives the rotation that internally toothed annulus is realized noseplate by miniature gears 4; The output shaft of HM Hydraulic Motor 1 is connected with worm screw 2 by spline; The oil inlet of HM Hydraulic Motor 1 and oil outlet are being connected the oil inlet and the oil outlet of bidirectional hydraulic lock 10 respectively.

Back base plate 8 upper outside face both sides are separately installed with hook 11, and lateral surface both sides, back base plate bottom are separately installed with lower draw-bar 12.

During use, get final product by going up on the door frame that hook and lower draw-bar be installed to the utility model fork truck of back base plate.During work, the fork truck high pressure oil drives HM Hydraulic Motor 1 and starts, the output shaft of HM Hydraulic Motor 1 is connected with worm screw 2 by spline, drive worm screw 2 rotations, worm screw 2 drives worm gear 3 and rotates worm gear 3 and miniature gears 4 coaxial rotation, the internally toothed annulus engagement of miniature gears 4 and pivoting support inner ring 5, miniature gears 4 rotating drive pivoting support inner rings 5 rotate, and pivoting support inner ring 5 and noseplate 6 are fixed by bolted connection, so noseplate 6 rotates with pivoting support inner ring 5.

Its drive path is: HM Hydraulic Motor 1 → worm screw 2 → worm gear 3 → miniature gears 4 → pivoting support inner ring 5 → noseplate 6;

Worm screw 2 → worm gear 3 is formed first order worm and gear and is slowed down, and the internally toothed annulus of miniature gears 4 → pivoting support inner ring 5 is formed second stage gear reduction.

Because HM Hydraulic Motor 1 is the low rotation speed large torque HM Hydraulic Motor, first order worm and gear slows down and second stage gear reduction all has very big reduction ratio, so noseplate 6 has very big output torque.

HM Hydraulic Motor 1 can positive and negative continuous running, realizes noseplate 6 positive and negative 360 ° of rotations continuously.

Bidirectional hydraulic lock 10 is installed at HM Hydraulic Motor 1 oil inlet and outlet place, when noseplate 6 turns to the optional position, if the high pressure oil of sever supply this moment HM Hydraulic Motor 1, bidirectional hydraulic lock 10 will be shut HM Hydraulic Motor 1 oil inlet and outlet, make that HM Hydraulic Motor 1 is positive and negative all can't rotate, thereby noseplate 6 is fixed on this optional position, realizes that noseplate 6 rotates to the optional position and can two-wayly lock.
