Description

[Detailed explanation of the invention] [Industrial application field] This invention is a lift vehicle used for moving work into high-rise buildings such as high-rise condominiums and high-rise housing complexes. This invention relates to a bucket swing device for a lift vehicle that makes it possible to load and unload cargo easily, quickly, and safely and reliably.

[Prior art and its problems]

2. Description of the Related Art Lift vehicles have been known for performing moving operations in high-rise buildings such as high-rise condominiums and high-rise housing complexes. In order to directly lift cargo to be transported to the balcony or window of a high-rise building, this lift vehicle is equipped with a carrier that ascends and descends along a guide rail that can be raised and lowered, and a bucket that loads the cargo. The structure is such that the bucket can be moved to the desired location by raising and lowering the bucket.

Therefore, in the bucket of the lift vehicle mentioned above, the undulation cylinder is interposed between the carrier and the bucket, and the undulation cylinder maintains the bucket in a horizontal state during transportation, and also allows the bucket to slide into the lower part of the bucket. It is known that a mechanism is provided to allow the bucket tote to slide back and forth, and to draw the bucket to a worker's hand after it has been moved to a desired position. Therefore, in a lift vehicle with such a structure, the bucket has a limited sliding width, so when loading or unloading cargo from the back of the bucket, for example, the worker must It is necessary for workers to load and unload cargo while riding on a bucket cart, and workers have to go to designated areas on the bucket cart to work, and especially when loading and unloading cargo at high places. This method is extremely dangerous, requires a great deal of labor, and has low work efficiency.

[Means and actions for solving problems]

In view of the above-mentioned problems, the present invention provides a lift vehicle in which an extending member that can rise and fall, expand and contract, and turn freely is attached to a movable trolley, and a bucket is provided on the carrier that moves up and down on the extended member. By arranging the bucket to the carrier via a turntable, loading and unloading cargo to and from predetermined locations on the bucket can be easily and safely ensured, and the simple structure improves work efficiency and improves work efficiency. It is an object of the present invention to provide a bucket swing device for a lift vehicle which makes it possible to shorten time.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

In FIG. 1, 1 is a moving lift vehicle used in the present invention, and this moving lift vehicle 1 has a turntable 3a rotatably provided on a movable trolley 2. is provided with an extending member (hereinafter referred to as a guide rail) 4 whose base is pivotally supported, and this guide rail 4 is raised and lowered by an undulation cylinder 5a provided between the turntable 3a and the guide rail 4, A telescopic cylinder 6 provided along the guide rail 4 or partially built-in allows it to be extended and contracted in multiple stages.

Reference numeral 7 denotes a carrier, and this carrier 7 is equipped with wheels 8 that engage with the guide rail 4, and the carrier 7 is provided with wheels 8 that engage with the guide rail 4, and is moved onto the guide rail 4 by feeding out and winding up a wire (not shown) stretched before and after the guide rail 4. It is designed to be able to move up and down.

Reference numeral 9 denotes a bucket with an open top surface on which cargo 10 is loaded, and a turntable 3b, which will be described later, is located at the bottom.
and a pedestal 11 integrally provided. This bucket 9 is pivotally supported at the tip of the carrier 7, and a undulation cylinder 5b is disposed between it and the carrier 7, and the bucket 9 is held in a horizontal position by the operation of this undulation cylinder 5b. While maintaining the movement of the guide rail 4 as the carrier 7 moves.
The baggage 10 is transported to a predetermined location by moving up and down along the road.

Reference numeral 12 denotes a slide mechanism provided on the bucket cart 9, and this slide mechanism 12 includes a bracket 13 vertically installed on the mount 11 of the bucket cart 9, and a sliding roller 14 pivotally supported on the bracket 13 in the width direction of the carrier 7. and a slider 15 that engages with this sliding roller 14.
can be slid back and forth.

Reference numeral 3b denotes a turntable provided at the bottom of the bucket cart 9, which allows the bucket cart 9 to be manually rotated 360 degrees via a large number of bearings provided on the outer periphery of the turntable. Reference numeral 16 denotes a hole through which a pin 17 is inserted for fixing the rotating position of the bucket bag 9. The insertion holes 16 are formed in the lower surfaces of the pedestal 11 and the bucket 9, and as shown in the figure, four insertion holes 16 are formed at equal intervals of 90 degrees.

The operation of the present invention configured as described above will be explained below.

First, the moving lift vehicle 1 is moved to the intended work site and fixed, and then the turntable 3a is rotated in a predetermined direction, the guide rail 4 is extended, and its tip is moved to the intended work site where the goods are to be loaded and unloaded. Facing high places. These operations are accurately performed by a well-known control device mounted on the lift vehicle 1. Then, on the ground, the bucket cart 9 is pulled closer to the worker's hand by the slide mechanism 12, and the cargo 10 is loaded onto the bucket cart 9. At this time, for example, at the back of the bucket cart 9 away from the worker's hand, the baggage 10 is loaded onto the bucket cart 9. When it is desired to load the baggage 10, the baggage 10 can be easily loaded at a desired location by rotating the bucket 9 toward the worker's hand via the turntable 3b. Conventionally, it was necessary for the worker to ride on the bucket cart 9 and place the cargo 10 at a predetermined position, but with the present invention, such a labor can be omitted and the cargo can be loaded at a desired location.

After loading the baggage 10 onto the bucket 9, the carrier 7 is raised and lowered, and the bucket 9, which is kept in a horizontal state by the undulating cylinder 5b, is placed on the guide rail 4.
Climb above and reach the desired height. Thus,
The cargo 10 is loaded and unloaded from the bucket 9 to a predetermined location. Here, too, the worker pulls the bucket 9 toward his hand and turns when unloading the cargo 10 at the back of the bucket 9, which is away from the worker's hand. Since the bucket 9 can be rotated toward the operator's hand via the table 3b, it is possible to move the bag 1 toward the worker's hand.
0 loading and unloading work is very safe and non-hazardous.
This enables reliable work. In order to prevent the bucket 9 from shaking during work, a pin 1 is inserted into the insertion hole 16.
By inserting 7, the bucket 9 can be fixed at every 90 degrees, allowing stable work.

[Effect of idea]

As described above, the present invention provides a lift vehicle in which an extending member that can rise and fall, expand and contract, and turn freely is attached to a movable trolley, and a bucket is provided on the carrier that moves up and down on the extended member. Since the bucket cart is installed through the tongue table, the bucket cart on which the cargo is loaded can be rotated freely, making it possible to easily move the bucket cart closer to the worker's hand. There is no need for a worker to take the trouble to board the bucket when loading or unloading cargo, so the work efficiency is significantly improved and there is no risk of unexpected danger being presented to the worker. Thus, according to the present invention, loading and unloading operations can be carried out quickly, safely and reliably, and the structure is simple and easy to manufacture.
