JPS59118611A - Bucket for elevator - Google Patents

Abstract

PURPOSE:To prevent a bottom plate fixing part from cracking to pieces, by installing each of reinforcement parts being large in expansion resistance in place nearby the front and rear ends of the bottom plate, while attaching these parts to a bucket frame as a structural formation, in case of an elevator bucket for conveying an adhesive substance. CONSTITUTION:Each of reinforcement parts 11, which are strong in expansion resistance and interposes each of core materials 11a of a woven fabric or the like, is installed in the front and rear ends of an expansile, flexible bottom plate 10 and fitly sandwiched between a front joint plate 2 and a front pressure plate 6 composed of a rigid material each as well as between a rear joint plate 3 and a rear pressure plate 8. With this constitution, these reinforcement parts 11 and 11 where the bottom plate 10 expands and contracts according to the resistance of a conveyed load running to and from a bucket, prevent any deformation of the bottom plate, thus cracking and breakdown can be checked.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packet used in an elevator for transporting sticky objects such as wet loose materials, and particularly to a structure of the packet that prevents the transported objects from adhering.

Conventionally, as shown in FIG. 1, an elevator packet for conveying adhesive objects such as bulk materials is constructed by connecting a pair of rigid side plates 1 to the front and rear (as shown in the figure) via a rigid front joint plate 2 and a rigid successor plate 3. The left and right sides) are connected to form a rigid packet frame 4. The front joint plate 2 and the successor plate 3 of this packet frame 4 are curved so that the bottom plate 5 made of a stretchable and flexible material can be freely deformed, and the front and rear ends of the bottom plate 5 are connected to each other.
(on the left side of the figure, the side where loose items are scooped up) is sandwiched between the front joint plate 2 and the rigid front pressure plate 6 and fixed via the tightening screws 7, and the rear edge of the bottom plate 5 is connected to the successor plate 3 and the rigid front pressure plate 6. It is sandwiched between the rear pressure plate 8 and fixed thereto via a fastening screw 9.

When a loose object is scooped up from the packet, the bottom plate 5 expands as shown by the chain line in the figure, and when the loose object is discharged, it contracts to its original size, shearing off the attached part of the loose object inside the packet. be.

However, the elastic and flexible bottom plate 5 has the disadvantage that, due to repeated expansion and contraction, cracks occur near the contact points of the front and rear pressure plates 6, 8 and the fastening screws 7.9 and the bottom plate 5 breaks.

SUMMARY OF THE INVENTION In view of the above drawbacks, it is an object of the present invention to provide an elevator packet that prevents cracking and breakage of the fixed portion of the expandable and flexible bottom plate.

The purpose of this invention is to provide portions with increased expansion and contraction resistance at the front and rear ends of a stretchable and flexible bottom plate, and to fix these portions with strong expansion and contraction resistance to a rigid packet frame so that the middle portion of the bottom plate can freely expand and contract. However, the parts fixed to the packet frame withstand external forces, prevent deformation, and suppress cracks and ruptures.

Embodiments of the invention will be described with reference to the drawings. FIG. 2 is a cross-sectional view showing one embodiment of the present invention, and the same reference numerals are used for parts common to the conventional one, and the explanation thereof will be omitted.

In FIG. 2, a reinforcement part 1 with strong expansion and contraction resistance has a core material 11a such as a woven fabric interposed at both front and rear ends of a stretchable and flexible bottom plate 10.
1 is provided, and the front and rear reinforcing parts 11 are sandwiched between the front joint plate 2 and the front pressure plate 6 and between the successor plate 3 and the rear pressure plate 8, respectively, which are made of a rigid material.

FIG. 3 shows an example in which the plate thickness at both ends of the bottom plate IO is increased to provide reinforcing portions 12 with stronger expansion and contraction resistance.

According to the above configuration, the bottom plate 1O expands and contracts in accordance with the resistance of the conveyed object in and out of the packet (the chain line in the figure shows the expanded state), but the reinforcing part 11 attached to the packet frame 4.
12 prevents deformation and suppresses crack rupture.

Note that the core material such as a woven fabric interposed in the reinforcing portion 11 may have a texture that is vertical and horizontal with respect to the direction of expansion and contraction of the bottom plate, or may have a texture that is diagonal.

As explained above, in this invention, the both side plates and the front successor plate of the packet are made into a rigid frame, and the front and rear ends of the stretchable and flexible bottom plate are reinforced and attached to this frame. It was possible to eliminate cracks and ruptures.
