Description

[Detailed description of the device]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device which allows a bucket of an inverted L-shaped skip hoist to be smoothly overturned and to be turned up to 180 °. A skip hoist is a bucket that reciprocates to transport substances,
It is a device that automatically falls the bucket and discharges the load at the end point, but since the bucket is large, it has the feature of being able to carry lumps and amorphous substances, and is widely used for the transportation of dust and scales. It is convenient to put the goods in the center of the tank if the transportation route is inverted L shape, that is, ┐ shape.

[Technique of Raira] Raira had to move the connecting pin between the chain and the bucket horizontally, and then the outer roller was dropped by the rail to make it fall. Since the rails cannot be installed in one plane because they intersect on the way, and the installation is spread over two planes, not only is the rail width wide, but the metal fittings that connect the buckets to the rollers and chain have a complicated structure. In addition, the falling speed was non-uniform and it was not possible to reverse 180 °.

[Problems to be Solved by the Invention] This invention installs four inner and outer rails continuously on one plane from the start point to the end without interruption, and absolutely between the inner and outer rails and between the chain and the rails. It is an object of the present invention to obtain a device that is configured so that it does not cross over and that can be operated simply and smoothly. The reason for not crossing is that the chain and the bucket are connected by the connecting pin, so if the chain and the rail intersect within one plane, this pin will cut the rail and it cannot operate. This is because if the rails cross, the connecting pin connecting the roller and the bucket hits the rail and the train cannot operate.

[Means for Solving the Problems] This device supports the vicinity of the center of gravity of a bucket with a connecting pin of a chain, and rolls two inner and outer rollers on each side of the bucket on a rail to reduce the weight of the load. By operating with support, by configuring the outer rail to be concentric with the chain wheel and the inner rail to be concentric semicircle at the end point, there is an unstable state in which the center of gravity is supported by the connecting pin and can easily fall. The inner and outer rollers of the bucket are guided by rails to control the bucket direction.

[Operation] In the system in which only the outer circular rail is installed and both bucket rollers are operated within this rail, the chain wheel and the rail are concentric, so that the bucket is prevented from rotating around the connecting pin. I can't do things. Also, when it is pulled up, it is only pulled up by a tensile force. The point is that in order to invert the bucket and return it to the upright, the lower part of the bucket is pushed or not pushed together with the circular movement of the bucket connecting pin. Since it works as a lever, it can easily lift a heavy bucket.

Therefore, naturally, the mounting position of the bucket roller is different, and the construction of the rail is also different. When the bucket falls, the inner semi-circular rail prevents the bucket from tipping over quickly, and the outer circular rail promotes the bucket to turn and causes the bucket to tip at a constant speed. Also, when restored, the inner roller acts as a lever and can easily raise a heavy bucket. Moreover, the hinged opening / closing rail is provided at the base of the inner semi-circular rail so that the bucket can be rotated 180 °.

[Embodiment] The structure of the present invention will be described with reference to an embodiment. Reference numeral 4 in FIG. 1 denotes a pair of drive sheaves driven by a motor 15. The drive sheave 1 and the main sheave 1 and the sheave sheave. 2, an idle chain wheel 3, two chains 5 are hooked between the chains 5, and connecting pins 7 of the chains are about 10 to 15 cm from the center of gravity of the bucket 6.
It supports points that are close to the horizontal forward direction rotatably. That is, the center of gravity of the bucket should always be behind the support point. 8
Is a roller installed in the upper rear part of the bucket 6 and 10 is installed in the lower front part of the bucket 6, which are installed diagonally to each other.

Numeral 9 is an auxiliary roller for keeping the bucket upright together with the auxiliary rail 17 when the bucket bends from the vertical direction to the horizontal direction. Reference numeral 13 is an outer rail, and 14 is an inner rail, and two rails are provided for each roller. Rollers 8 and 10 roll inside the rails to support the weight of the bucket for operation.

Reference numeral 13 is a fall point and is an outer roller of the bucket.
A circular rail concentrically provided with the chain wheel 1 with a radius between the outer edge of 8 and the center of the chain wheel as a radius, and 12 as an end point of the rail 14 and a distance between the outer edge of the inner roller 10 of the bucket and the center of the chain wheel. Is a semi-circular rail with a radius of.
Reference numeral 17 is a rail for the auxiliary roller 9, which is provided only at the bent portion. Reference numeral 11 denotes a chain drooping prevention material, which is provided below the main chain wheel 1.

Reference numeral 16 denotes an opening / closing rail which is attached to the base of the semi-circular rail 12 by a hinge, and one of which is supported by a protruding piece of 12 and has a structure which opens upward but does not open downward.

The operation will now be described. When the drive chain wheel 4 is driven by the motor 15, the bucket 6 is driven by the chain 5.
The rollers 8 and 10 are each rail 1
As it rolls in 3 and 14, it keeps upright and rises. When the bucket, which has been changed in direction at the upper bending portion, moves horizontally and eventually reaches the falling portion, the connecting pin 7 of the bucket starts to turn around the outer periphery of the main chain car 1 as shown in FIG. Lifted by 13, the bucket begins to fall.

As the main chain vehicle 1 turns, the bucket continues to fall in the situations shown by numbers 1 to 5 in FIG. 3, and the roller 8 rolls on the rail 13 and the roller 10 rolls on the semi-circular rail 12. When the center of gravity of the bucket goes out to the pink side, the bucket tries to fall suddenly, but the roller 10 moves to the rail 1
Since it is pushed at 2, it prevents the bucket from falling suddenly and advances at a constant speed. The bucket will eventually be 18 shown in FIG.
Although it reaches the 0 ° tipping position, even if the bucket overturns by 180 ° or more, the roller 10 only pushes the hinge rail 16 open, and there is no problem. If there is not 16, it is impossible to suddenly stop a heavy bucket, so it cannot turn 180 degrees. The ability to fall 180 ° also facilitates the transportation of sticky substances. Then, the bucket returns in the opposite direction, but as the pink turns, the rollers 10 on the semi-circular rails 12 serve as levers for raising the bucket, and the heavy bucket can be easily raised.
In this way, the load is transported back and forth between the loading section and the falling discharge section.

[Advantages of the Invention] With the configuration as described above,
The inner and outer rollers of the bucket and the inner and outer rails hold the bucket firmly, and the bucket is rotated by the rotation of the main chain car. Therefore, the bucket can be easily overturned and restored, and it is a large and heavy-duty bucket. It became possible to use, and mass transportation became possible. In addition, if you replace the bucket with a holder that accommodates the dolly, it is easy to lift the dolly that carried the load and to topple the dolly. It is possible to overturn and discharge only the load.

By providing a rail that can be opened and closed with a hinge at the base of the semi-circular rail, the bucket can be turned over 180 ° and the adhesive substance can be transported.
