Description
【発明の詳細な説明】 本発明は荷上げ装置に関するものである。[Detailed description of the invention] The present invention relates to a loading device.
この種荷上げ装置としては荷台の下部に設けた
パンタグラフ式の伸縮腕を油圧機構等を使用して
上下動させるものがあるが、油圧機構等が高価で
使用目的に応じきれない場合が多く、又水平に荷
台を上下させることは極めて困難であるばかり
か、無駄な空間が大きくなり空間の有効利用がで
きない等の欠点を有する。 This type of loading device uses a hydraulic mechanism to move up and down a pantograph-type telescoping arm installed at the bottom of the loading platform, but in many cases, the hydraulic mechanism is expensive and cannot be used for the intended purpose. Further, it is not only extremely difficult to raise and lower the loading platform horizontally, but also has the disadvantage that it wastes a large amount of space, making it impossible to utilize the space effectively.
本発明はこれらの欠点を解消すべく研究された
もので一方向にのみ屈曲自在のローラチエーン
と、上下の歯車の噛合による機械的な作動により
荷台を押し上げようとし、もつて狭い空間の有効
利用を計ると共に安価で且常に水平を保持した上
下動を正確、確実に行なわんとするものである。 The present invention has been researched to eliminate these drawbacks, and uses a roller chain that can be bent in only one direction and mechanical operation through the meshing of upper and lower gears to push up the loading platform, thereby making effective use of narrow spaces. The objective is to accurately and reliably perform vertical movement while keeping the horizontal position at low cost.

A pair of driving gears 3 that move together are supported by bearings 4 at a position closer to the example, and driven gears 5, 5 are supported by bearings 6, 6 at the lower part of the loading platform 2 so as to correspond to the driving gears 3. , driving gear 3 and driven gear 5,
A roller chain 7 with an end is hung around 5 and one end is fixed to a fixture 8 of the base 1. This roller chain 7 has attachment parts 9, 9', 10, 1 provided on one side of the links constituting the roller chain 7.

The leading edges of 1, 11', 12, 12', . . . are curved. A bending prevention body 11 is provided at the corner position of the roller chain 7 that can be hung around the gears 3, 5, and 5.
Separation preventing bodies 13, 13', 13'' which are in contact with the tip edges of 11'...12, 12'...... are fixed to prevent the roller chain 7 and the gears 3, 5, 5 from coming off.
The sliding surfaces 14 of the detachment prevention bodies 13, 13', 13'' are pasted with slippery synthetic resin plates.

ても良い。 In the figure, reference numeral 15 denotes a groove-shaped guide for guiding the other end of the roller chain 7. One end is close to the bending prevention body 13, and the other end is bent upward by 180 degrees.
6 is a storage receptacle for the roller chain 7. Reference numeral 17 denotes a prime mover, which can freely drive the drive gear 3 in forward and reverse directions via pulleys 18, 18', and 18''.Although two driven gears are shown as a set, it is also possible to use a single driven gear.

良い。 The present invention is realized as described above, and its operation will be explained. By loading cargo onto the loading platform 2 and driving the prime mover 17, the storage receiver 16 and the roller chain 7 on the guide 15 are sequentially paid out. The loading platform 2 rises horizontally by a distance that is one-half of the amount by which the roller chain 7 is fed out. When lowering the loading platform 2, the prime mover 17 may be reversed.

が少ないので空間の効果的な利用ができる。 As described above, the present invention consists of a base and a loading platform that moves up and down, and a roller chain that can be bent only in one direction is suspended between the driving gear bearing the bearing on the base and the driven gear bearing bearing the bearing on the loading platform. One end of the roller chain is fixed to the base, and a detachment prevention body is fixed at the corner position of the roller chain where it can be hung around the drive gear and driven gear.The drive gear can be driven forward or backward by the prime mover, so that the loading platform can be Even if it tries to fall to one side, the roller chains that stand upright on both sides of the driven gear interact with each other and can always move up and down in a stable manner without bending.Also, they can always move up and down while maintaining a horizontal position, so that the load is not accidentally moved. There is no risk of falling. In addition, the effective travel distance of the loading platform is 1/2 of the amount of payout (travel) of the roller chain, allowing fine adjustment of vertical movement, and conversely, the thrust of the roller chain is 1/2 of the uplift load. Therefore, the prime mover has relatively low horsepower and can be provided at a good price. Also, since there is little dead space, space can be used effectively.
