Detailed Description
The technical scheme of the present utility model will be clearly and completely described in the following detailed description. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 to 4, a dual drive lifting assembly for a heavy duty stacker, as in the prior art, comprises a lifting drum 1. However, since the lifting assembly in the prior art adopts a driving motor and directly connects the lifting reel with the output shaft of the driving motor, thereby reducing the service life of the driving motor and also being unable to be used for heavy-duty stacking machine, the lifting assembly is provided with two driving motors 2, and a reel bracket 3 is additionally arranged for the lifting reel 1 so as to erect the lifting reel 1. The two sides of the winding drum bracket 3 are respectively provided with a fixed bearing seat 4 and a floating bearing seat 5, the two driving motors 2 are respectively symmetrically arranged at the two sides of the winding drum bracket 3, the central positions of the two axial end surfaces of the lifting winding drum 1 are respectively provided with a winding drum shaft 6 along the axial direction of the winding drum, and the two winding drum shafts 6 respectively penetrate through the fixed bearing seat 4 and the floating bearing seat 5 and are in driving connection with the two driving motors 2.
In this embodiment, the section of the spool support 3 is U-shaped and is disposed with the opening facing upwards, the spool support 3 is provided with mounting plates 7 along the radial direction of the lifting spool 1 at both sides of the axial direction of the lifting spool 1, and the fixed bearing seat 4 and the floating bearing seat 5 are fixedly disposed on the mounting plates 7 and coaxially disposed. The floating bearing seat 5 is used for compensating thermal expansion, and because the materials and the temperature rising speeds of the spool shaft 6 and the bearing seat are inconsistent, different axial expansion amounts of the spool shaft 6 and the bearing seat can be caused, and the force generated by the redundant expansion amounts directly acts on the bearing, the floating bearing in the floating bearing seat 5 only radially supports the spool shaft 6 at one end of the floating bearing, so that the spool shaft 6 has certain axial displacement, and the interaction force between the spool shaft 6 and the floating bearing is avoided.
The lifting reel frame 1 is arranged on the reel bracket 3 so as to avoid the lifting reel 1 from being directly hung on the output shaft of the driving motor 2, thereby prolonging the service life of the driving motor 2. Meanwhile, the lifting drum 1 and the drum bracket 3 are installed through heavy bearing seats, so that the lifting requirement of overweight occasions is met.
The lifting reel 1 is placed in the opening of the reel holder 3 and at least 2/3 of the lifting reel is covered by the reel holder 3, i.e. one side of the reel holder 3 is arranged lower than the reel shaft 6 and the other side is arranged at least flush with the top of the lifting reel 1, so that the stability of the lifting reel 1 during lifting is ensured.
In order to further expand the diameter and the length of the lifting reel 1 so as to meet the use situation of the ultra-high overweight narrow roadway, the extending drums 8 are respectively arranged on the circumferential sides of the two axial ends of the lifting reel 1 in an extending mode so as to further increase the length of the lifting reel 1, a plurality of reinforcing rib plates 9 are uniformly arranged between the inner side walls of the extending drums 8 and the two axial end faces of the lifting reel 1, the structural strength of the lifting reel 1 is improved through the reinforcing rib plates 9, and a structural foundation is provided for expanding the diameter of the lifting reel 1.
The lifting reel 1 and the extension tube 8 are respectively provided with a wire rope 10 in a winding way, and in order to guide the wire rope 10 to be wound and unwound regularly, the circumference outer side surfaces of the lifting reel 1 and the extension tube 8 are uniformly provided with thread-shaped rope grooves 11 so that the wire rope 10 is wound in the rope grooves 11. Meanwhile, during the working process of the heavy stacker, the steel wire rope 10 may shake or jump under the influence of the outside in the unreeling or reeling process, so that the steel wire rope cannot be reeled into the rope groove 11 or uniformly released along the thread direction of the rope groove 11, and therefore, a rope guide plate 12 is further movably arranged on the reel bracket 3 along the axial direction of the lifting reel 1.
The rope guide plate 12 is uniformly provided with a plurality of strip-shaped through holes 13 which are arranged along the radial direction of the lifting reel 1, and bolts 14 are arranged in at least two strip-shaped through holes 13 in a penetrating way and are in threaded connection with one side of the reel bracket 3 so as to movably fix the rope guide plate 12 on the reel bracket 3. The rope guide plate 12 forms a rope pressing action side close to the lifting drum 1 and keeps abutting contact with the steel wire rope 10 on the lifting drum 1, namely, the distance between the rope pressing action side of the rope guide plate 12 and the lifting drum 1 is smaller than or equal to the diameter of the steel wire rope 10, so that the effect of forcing the steel wire rope 10 to be unreeled or rolled only along the spiral direction of the rope groove 11 is achieved. According to different specification diameters of the steel wire rope 10, the distance between the rope guide plate 12 and the lifting drum 1 can be kept in abutting contact with the steel wire rope 10 all the time by adjusting the position of the bolt 14 in the strip-shaped through hole 13 on the rope pressing action side of the rope guide plate 12. The above-mentioned side of the spool support 3 which is lower than the spool shaft 6 is the side provided with the rope guide 12.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model. Thus, the present utility model is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
