By operating reciprocally, the hydraulic mechanism 11 is pressurized, and the frame 17 can be lifted by the hydraulic mechanism 11, which makes it convenient to transport cargo on the pallet. Pallet truck 1 is brake In order to stop the hydraulic pallet truck 1 because there is no structure, the operator operating the hydraulic pallet truck 1 applies a force to forcibly stop the movement of the hydraulic pallet truck 1 so that the operator's force is small. For example, the hydraulic pallet truck 1 cannot be stopped reliably, and when an article is loaded on the hydraulic pallet truck 1 and moved on an inclined surface, there is gravitational acceleration. If the movement speed of the pallet truck 1 cannot be controlled, if the hydraulic pallet truck 1 cannot be stopped immediately, there is a risk of injury to the other person.

本発明によれば、図9乃至図13のように、油圧パレットトラック2が、移動中、停止する場合、操作者が、足で、ブレーキ構造4の足板44を踏むだけで(図9乃至図11のように)、足板44のコンロッド440が、枢着素子444を支軸として、下へ旋動し、コンロッド440により、横棒42が連動されて下へ変位し、横棒42により、二つの位置決め片406が押されて下へ変位し、二つの位置決め片406が、支柱404に沿って下へ変位し、これにより、下方にあるスプリング405が、付勢され、弾性圧縮状態になり、横棒42が下へ変位すると、枠体40の上方にある支持枠45が連動されて下へ変位し、支持枠45により、上方にある連動座46が下へ変位し、連動座46により、一側にあるブレーキパッド座49が下へ変位し、ブレーキパッド座49の底面に位置するブレーキパッド490が、油圧パレットトラック2の車輪27に貼り付いて、車輪27が回転できなくなり、そのため、油圧パレットトラック2が、安定的に且つ快速的に停止され、停止状態を維持したい場合、足板44を下へ押さえながら一側へ変位させると、足板44のコンロッド440により、枢着素子444上に設置されたスプリング445が、付勢されて弾性圧縮状態になり、そして、足板44のコンロッド440が、蓋板43の嵌合槽431に嵌設されて位置決められ、そのブレーキパッド490が、持続的に、安定に車輪27に貼り付いて、車輪27が回転不可に維持され、ブレーキを解除する場合、足板44を下へ押するだけで、そのスプリング445が、弾性回復により、コンロッド440が、蓋板43の摺動槽430内に押し戻され、また、枠体40内のスプリング405の弾性回復により、横棒42と足板44及び支持枠45が、上へ元の位置に押し戻され、支持枠45により、上方にある連動座46とブレーキパッド座49が、連動されて上へ移動し、ブレーキパッド490が、車輪27に接触しなくなり、ブレーキが解除され、また、操作者が、油圧パレットトラック2のグリップ21上に設置されたブレーキグリップ5を、手で、ブレーキグリップ5を押すことにより、ブレーキワイヤー473を引くことができ(図12と図13のように)、ブレーキワイヤー473が、上へ引かれると、二つのスイングアーム47、48が、対向に近付き、二つのスイングアーム47、48の間に位置するスプリング474が、圧縮されて弾性圧縮状態になり、二つの連動座46が、それぞれ、二つの支持枠45上の枢着軸453を支軸とし、二つの連動座46の下端が、二つのスイングアーム47、48によって引かれて二つのスイングアーム47、48に連動されて内上方へ旋動され、また、二つの連動座46の上端が、外下方へ旋動し、二つの連動座46の上端により、二つのブレーキパッド座49が連動されて外下方へ旋動され、ブレーキパッド座49の底面にあるブレーキパッド490の外側が、油圧パレットトラック2の車輪27に接触し、車輪27とブレーキパッド490の外側部位とが接触して摩擦力が発生して、車輪27の回転数が低減され、これにより、油圧パレットトラック2が減速され、そのため、足踏み方式により、油圧パレットトラック2が、安定的に停止され、また、手動方式により、油圧パレットトラック2を減速させることができ、油圧パレットトラック2の操作安全性が向上される。     According to the present invention, as shown in FIGS. 9 to 13, when the hydraulic pallet truck 2 stops during movement, the operator simply steps on the foot plate 44 of the brake structure 4 with his feet (FIGS. 9 to 9). As shown in FIG. 11, the connecting rod 440 of the foot plate 44 pivots downward with the pivoting element 444 as a support shaft, and the horizontal rod 42 is displaced downward by the connecting rod 440. The two positioning pieces 406 are pushed and displaced downward, and the two positioning pieces 406 are displaced downward along the support pillars 404, whereby the lower springs 405 are urged and elastically compressed. When the horizontal bar 42 is displaced downward, the support frame 45 above the frame body 40 is interlocked and displaced downward. The support frame 45 causes the interlocking seat 46 above to be displaced downward. The brake pad seat 49 on one side The brake pad 490 that is displaced and located on the bottom surface of the brake pad seat 49 sticks to the wheel 27 of the hydraulic pallet truck 2 so that the wheel 27 cannot be rotated. Therefore, the hydraulic pallet truck 2 is stable and fast. When it is desired to maintain the stopped state, the spring 445 installed on the pivoting element 444 is biased by the connecting rod 440 of the foot plate 44 when the foot plate 44 is displaced downward while being pressed down. The connecting rod 440 of the foot plate 44 is positioned by being fitted in the fitting tank 431 of the lid plate 43, and the brake pad 490 sticks to the wheel 27 continuously and stably. Thus, when the wheel 27 is kept non-rotatable and the brake is released, the spring 445 can be recovered by elastic recovery simply by pushing the foot plate 44 downward. The connecting rod 440 is pushed back into the sliding tank 430 of the lid plate 43, and the horizontal bar 42, the foot plate 44, and the support frame 45 are returned to the original positions by the elastic recovery of the spring 405 in the frame body 40. When the support frame 45 is pushed back, the upper interlocking seat 46 and the brake pad seat 49 are interlocked and moved upward, the brake pad 490 does not contact the wheel 27, the brake is released, and the operator However, when the brake grip 5 installed on the grip 21 of the hydraulic pallet truck 2 is pushed by hand, the brake wire 473 can be pulled (as shown in FIGS. 12 and 13), and the brake When the wire 473 is pulled upward, the two swing arms 47 and 48 come close to each other and are located between the two swing arms 47 and 48. 474 is compressed into an elastically compressed state, and the two interlocking seats 46 each have a pivot shaft 453 on the two support frames 45 as a support shaft, and the lower ends of the two interlocking seats 46 are two swings. Pulled by the arms 47 and 48 and interlocked with the two swing arms 47 and 48 and pivoted inward and upward, and the upper ends of the two interlocking seats 46 pivoted outward and downward. The upper end causes the two brake pad seats 49 to be interlocked and pivoted outward and downward, and the outside of the brake pad 490 on the bottom surface of the brake pad seat 49 comes into contact with the wheels 27 of the hydraulic pallet truck 2. The outer part of the pad 490 comes into contact with it to generate a frictional force, and the rotational speed of the wheels 27 is reduced. As a result, the hydraulic pallet truck 2 is decelerated. DOO track 2 is stopped stably, also manually method, it is possible to decelerate the hydraulic pallet truck 2, the operation safety of the hydraulic pallet truck 2 is improved.

本発明によれば、ブレーキパッド490と車輪27の外壁面とのピッチを調整可能であり、また、調整する時、横棒42の上、下方にあるナット423を、支持枠45のスクリューロッド450上で、上か下へ旋動するだけで、支持枠45のスクリューロッド450が枠体40外に突出する高さを調整でき、これにより、ブレーキパッド490と車輪27の外壁面とのピッチが設定され、また、本発明によれば、連動座46上に設置された縦方向摺動槽460と円弧摺動槽461を利用して、ブレーキパッド座49の角度を調整でき、ブレーキパッド490が、車輪27に貼り付く貼合角度を調整でき、これにより、ブレーキパッド490が、確実に車輪27に貼り付き、最も良い制動効果が得られる。     According to the present invention, the pitch between the brake pad 490 and the outer wall surface of the wheel 27 can be adjusted, and when adjusting, the nut 423 above and below the horizontal bar 42 is attached to the screw rod 450 of the support frame 45. The height at which the screw rod 450 of the support frame 45 protrudes out of the frame body 40 can be adjusted simply by turning up or down, so that the pitch between the brake pad 490 and the outer wall surface of the wheel 27 can be adjusted. In addition, according to the present invention, the angle of the brake pad seat 49 can be adjusted using the longitudinal sliding tank 460 and the arc sliding tank 461 installed on the interlocking seat 46, and the brake pad 490 The bonding angle that sticks to the wheel 27 can be adjusted, whereby the brake pad 490 is reliably stuck to the wheel 27 and the best braking effect is obtained.

そのため、本発明は、より進歩的かつより実用的で、法に従って特許請求を出願する。     As such, the present invention is more progressive and more practical, and claims are filed according to law.
