Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a lifting/lowering and multilevel parking system for heavy objects such as trucks and buses, and more specifically, a lifting/lowering device for lifting and lowering heavy objects such as trucks, buses, etc., and large machinery. , multilevel parking device.

Devices used for moving cargo to multi-level parking facilities, equipment for repair and inspection of the vehicles mentioned above, multi-dimensional storage of heavy objects such as large machinery, exhibition stands, etc., especially pallets for loading heavy objects such as trucks and buses. This relates to a device that uses a link chain to move up and down and safely stop at any position.

(Prior Art) Conventionally, as a vehicle lifting device used in this type of multi-level parking system, a method using a hydraulic device and a method using a chain device are generally widely known for raising and lowering the pallet of the vehicle mounting platform. However, the equipment of any number of systems is a complicated mechanism, has to be large, and the equipment is also quite expensive.
For this reason, there is a problem in that it can only be used as a multilevel parking system that accommodates a considerable number of parking spaces. In addition, since the turning radius of large vehicles such as trucks and buses is considerably larger than that of passenger cars, a multilevel parking system using the above-mentioned elevating device would take up countless spaces, making it uneconomical in practice. A multi-level parking system using a truck requires even more space, and such a multi-level parking system for trucks cannot be installed in the city center. Due to this current situation, toll truck carriers have to constantly transport their trucks from the city center to remote areas in the suburbs just to park their trucks, and there is a problem in that rental fees and other maintenance costs are high.

(Problems to be Solved by the Invention) The present invention was invented in view of the current situation, and the first object of the present invention is to provide a hydraulic system for lifting and lowering a pallet on a platform of an electric ffl object such as a truck. For those who want to obtain a simple lifting device with a simple structure of a link chain method without using a chain method, especially for large vehicles such as trucks and buses, which can be easily installed even in narrow spaces in the city center, etc. We provide an inexpensive elevating and multi-level parking device that is suitable for single-heavy loads for other vehicles. The purpose is to make the device usable for on-site repair and inspection bits, etc. A second object of the present invention is to provide a safe device that prevents the pallet from falling so that the pallet is stably supported at the predetermined position after being raised to a predetermined height.

(Means for Solving the Problems) The structure of the present invention which solves the problems of the conventional art as described above is as follows. and the left and right frame bodies,
One side is suspended by a link chain of a ``heart chain block'' suspended from one end of the beam, and the other is received by a link chain suspended from the other end of the beam. A pallet for storing electrical valuables such as trucks and buses can be horizontally raised and lowered by the synchronized drive of the electric chain block using the pillar 9 as a guide, and the link chain is connected to both sides of the pallet directly below the suspension. The pallet e is received via the lower surface of the sprocket attached to the chain, passes through both sides of the pallet, hangs down via the upper surface of the sprocket attached to both sides of the pallet directly below the electric chain block, and is tightly attached to the chain fixing part. The device is characterized by having wheels attached to the lower ends of each of the supports, thereby making the entire device movable.

The present invention also provides a second aspect of the present invention, in which racks are attached to the upper and lower sides of the opposing inner surfaces of the left and right columns, which are located at right angles to both sides of the pallet, of the four corner columns constituting the frame; A locking device with a tension spring attached to the rear side of the unit normally engages the protrusion on the side with the lever rod, lifts up the tip of the operating rod extending from the lever, and locks it in place. While pressed against the lower end of the shaft, it is separated from the ladder rack, and if the lifting load becomes negative due to chain breakage, etc., the shaft will descend due to its own weight and the tensile force of the spring tensioned at the bottom. , and along with that, the above-mentioned operating rod,
The lock of the locking tool via the lever rod and the projection is released and the locking device is fitted and locked to the ladder-like rack, and is further provided with a stop device for preventing falling. Wheels are attached to make the entire device movable.

(Function) According to the present invention as described above, first of all, as the first invention,
As a lifting device for a pallet on a platform that can be raised and lowered freely between the frame bodies with all four corner supports as guides, there is a hanging shaft member on which a link chain related to an electric chain block is hung on one both sides of the pallet, and a hanging shaft member in the vicinity thereof. A sprocket HL is attached to the bottom,
The other side of the pallet is connected by a link chain that is stretched from the chain fixing part directly below it, through the top surface of the sprocket, through the bottom surface of the sprocket attached to the other side of the pallet, and to the suspension parts of the upper left and right beams directly above it. Since both sides of the pallet are received by the electric chain block, when one of the two sides of the pallet pulls up the hanging shaft, the pulling force also acts on the sprocket attached to the lower part of the pallet, causing tension. The pallet rotates and moves upward while pulling the link chain, but since the link chain to be stretched is a certain length, the sprockets attached to the other side of the pallet also rotate while pulling the link chain. Conversely, when the suspension shafts on both sides of one of the pallets are loosened and lowered by the drive of an electric chain block, the sprockets attached to the lower part of the pallet are also rotated and lowered to create a tensioning link chain. In order to loosen the pallet, the other side of the pallet is lowered on the received link chain while rotating the sprockets attached to both sides due to its own weight, so the pallet can easily rise and lower while always maintaining a horizontal position. hf: Can be done.

Further, regarding the second invention, by configuring the stop device for preventing the pallet from falling, which is attached to the proximal part of the ladder-like rack attached to the supports at the four corners of both sides of the pallet, as described above, In an emergency, such as when one of the lifting shaft members each equipped with a downward tensile spring or the link chain that suspends and supports the sprocket shaft member is severed, the lifting or receiving load may be negative. The shaft material, which has become erected, falls suddenly downwards due to its spring and its own weight, pushing down the tip of the operating rod provided on the lever lever that presses against the lower end of the shaft material, thereby causing one end of the lever rod to engage the locking tool. Since the protrusion is released, the locking device is rotated by the tension of the spring at the rear of the locking device to engage and lock the tip of the locking device with one piece of the ladder-like rack adjacent to the locking device. The problem will be solved.

(Example) Hereinafter, examples of the present invention will be described based on the accompanying drawings.
