Description

本発明は、基台と昇降台との間に介装されたX字状のリフトアームを起倒させることによって、昇降台を昇降させるXリンク式昇降装置に関するものである。   The present invention relates to an X-link lifting device that lifts and lowers a lifting platform by raising and lowering an X-shaped lift arm interposed between the base and the lifting platform.

Xリンク式昇降装置は基台と昇降台を設けその中間にX字状に組み合わせたリフトアームが有り、それらはお互いの中間点で回転自在になるようセンターピンを備えている。X字状のリフトアームの2本のアーム(インナーアームとアウターアーム)の内、インナーアームは下側で基台に回転自在につながれ他の側は車輪を有しそれで昇降台を支えている。アウターアームは上側で昇降台に回転自在につながれ他の側は車輪を有しそれが基台の上を転がって動くようになっている。更にX字状に組み合わされたリフトアームは2組設けてありそれらが同期して動くように梁で連結されておりリフトアームが開閉されることで2組のX字状のリフトアームは同期して動き、昇降台は4点で支持され水平を保ちながら上下動する。 The X-link lifting device has a base and a lifting platform, and has a lift arm that is combined in an X-shape between them. Each of them has a center pin so as to be rotatable at a midpoint between them. Of the two arms (inner arm and outer arm) of the X-shaped lift arm, the inner arm is rotatably connected to the base on the lower side, and the other side has wheels to support the lifting platform. The outer arm is rotatably connected to the lifting platform on the upper side, and the other side has wheels so that it can roll on the base. Furthermore, two sets of lift arms combined in an X shape are provided and are connected by beams so that they move synchronously, and the two sets of X shape lift arms are synchronized by opening and closing the lift arms. The elevating platform is supported at 4 points and moves up and down while keeping the level.

従来のテーブルリフトなどは、油圧シリンダーのピストンロッドの先端をX字状のリフトアームの片方の連結梁と回転自在に連結し,油圧シリンダー本体の底部と他のX字状のリフトアームの連結梁を回転自在に連結し油圧シリンダーのピストンロッドを出すことでX字状のリフトアームの上下方向の交差角を開いて昇降台を上昇駆動し、油圧シリンダーの作動油を逃がしてピストンロッドを引っ込めることでX字状のリフトアームの上下方向の交差角を閉じて昇降台の下降駆動を行っている。 In the conventional table lift, the tip of the piston rod of the hydraulic cylinder is rotatably connected to one connecting beam of the X-shaped lift arm, and the bottom of the hydraulic cylinder body is connected to the other X-shaped lift arm. The piston rod of the hydraulic cylinder is pulled out by rotating the cylinder and opening the crossing angle in the vertical direction of the X-shaped lift arm to drive the lift up and down to release the hydraulic cylinder hydraulic oil and retract the piston rod Then, the vertical crossing angle of the X-shaped lift arm is closed to drive the lifting platform downward.

また、前記テーブルリフトに上記左右一対のX字状のリフトアームの結合部を中心にして開閉するX字状のリフトアーム(インナーアームとアウターアーム)を上下に複数重ねて連結したテーブルリフトなどもある。 Also, a table lift or the like in which a plurality of X-shaped lift arms (inner arms and outer arms) that open and close around the connecting portion of the pair of left and right X-shaped lift arms is connected to the table lift in the vertical direction. is there.

このようなリフトとして、例えば特許文献1・2・3或いは特許文献4の構成のものが知られており、特許文献1に記載された車両整備用リフトは、下段リフトで車ごと持ち上げ、上段リフトでタイヤ間のロッカーパネルを持ち上げタイヤをフリーにできるようにしたXリンク式昇降装置のものである。また、特許文献2に記載されているテーブルリフトは、工場等で使用され各種の荷物を昇降させるXリンク式昇降装置である。更に特許文献

のXリンクを、上下に積重ねた2段Xリンク式昇降装置である。
As such lifts, for example, those having the structure of Patent Documents 1, 2, 3 or Patent Document 4 are known, and the vehicle maintenance lift described in Patent Document 1 is lifted for each vehicle by a lower lift, and an upper lift. Thus, the X-link lifting and lowering device can lift the rocker panel between the tires to make the tire free. Moreover, the table lift described in Patent Document 2 is an X-link type lifting device that is used in a factory or the like and lifts various cargoes. Furthermore, the two-stage table lift described in Patent Document 3 is a two-stage X-link lifting device in which the X links of the X-link lifting device described in Patent Document 1 are stacked up and down.

上記特許文献1・2・3に記載のXリンクは共に板材であるため、横荷重が加わっても耐えられるようリンクの厚みを増すか、いろいろな機構を設けリンクの厚みを抑えるよう対処している。更に縦からの荷重は、リンクの幅を広げ最良の幅にして対処している。よって、縦からの荷重が多ければ剛性を増すためにリンクの幅を広げなければならず、また、荷重がズレたりすると偏荷重となり横荷重となるため、リンクを厚くし耐えられるようにしなければならないので、最低地上高の高い、幅の広い、高価なXリンク式昇降装置となってしまった。 Since the X links described in Patent Documents 1, 2, and 3 are both plate materials, the link thickness should be increased to withstand even when a lateral load is applied, or various mechanisms can be provided to reduce the link thickness. Yes. Furthermore, the load from the vertical is dealt with by widening the link and making it the best width. Therefore, if the load from the vertical is large, the width of the link must be widened to increase rigidity, and if the load deviates, it becomes an unbalanced load and becomes a lateral load. As a result, it has become a wide, expensive X-link lifting device with a minimum ground clearance.

また、特許文献4に記載の車両用昇降台装置のXリンクは、2段重ねのXリンクとなっている。1段目の下交差レバー部材はU字状の形状(凹状)をし、左右2つの各下交差レバー部材の交差点の側面にて、第一枢支部により接続されてXリンクを形成している。更に2段目の上交差レバー部材は板材になっており、左右2つの各上交差レバー部材の交差点にて第一枢支部により接続され、Xリンクを形成している。更に、前記各下交差レバー部材の上部領域と各上交差レバー部材の下部領域において、第2枢支部によって接続され2段重ねのXリンクを形成している。よって、車両用昇降台装置の支持部材(受台)が下降位置にある時、U字形状の凹部に2段目の上交差レバー部材が陥入し、最低地上高を抑えている。 In addition, the X link of the vehicle lifting platform device described in Patent Document 4 is a two-tiered X link. The first lower cross lever member has a U-shape (concave shape), and is connected by a first pivotal support portion on the side surface of the intersection of the two left and right lower cross lever members to form an X link. Further, the upper cross lever member in the second stage is a plate material, and is connected by a first pivotal support portion at the intersection of the two left and right upper cross lever members to form an X link. Further, the upper region of each lower cross lever member and the lower region of each upper cross lever member are connected by a second pivotal support portion to form a two-tiered X link. Therefore, when the support member (the cradle) of the vehicle lifting / lowering platform device is in the lowered position, the second-stage upper crossing lever member is recessed into the U-shaped concave portion, and the minimum ground clearance is suppressed.

上記特許文献4に記載の車両用昇降台装置の1段目の下交差レバー部材はU字状の形状(凹状)になっているため、各下交差レバー部材の交差点の側面にて、第一枢支部により接続されているため、横荷重などの偏荷重が掛かった場合リンクに曲げやねじりが発生するので、剛性を増さなければならず板厚の厚い部材が必要となっていた。 Since the lower cross lever member of the first stage of the vehicle lifting platform device described in Patent Document 4 has a U-shape (concave shape), the first pivot portion is formed on the side surface of the cross point of each lower cross lever member. Therefore, the link is bent or twisted when an unbalanced load such as a lateral load is applied. Therefore, the rigidity has to be increased and a member having a large plate thickness is required.

更に、特許文献1の図2にあるような上段リフトのサイドより車を受けるスイングアームが設けられているリフトにおいては、尚更横荷重などの偏荷重が掛かり剛性を増したリンクを必要とされるため、幅が広く分厚いリンクとなり、そのため最低地上高の高い、各Xリンク間の広い(受台幅が広い)、高価なXリンク式昇降装置となっていた。 Further, in a lift provided with a swing arm that receives a vehicle from the side of the upper lift as shown in FIG. 2 of Patent Document 1, a link having increased rigidity is required due to a further load such as a lateral load. For this reason, the link is wide and thick, and therefore the X-link type lifting device is wide and expensive (the width of the pedestal is wide) between the X links with a high minimum ground clearance.

本発明は、上記した従来の問題点を解消し、最小限の剛性の最良のリンクを使用することで、横荷重などの偏荷重が掛かっても丈夫な、幅の狭い、最低地上高の低い、各Xリンク間の狭い(受台幅が小さい)、安価なXリンク式昇降装置を提供することを目的としてなされたものである。 The present invention eliminates the above-mentioned conventional problems and uses the best link with the minimum rigidity, so that it is strong even when an uneven load such as a lateral load is applied, narrow, and has a low minimum ground clearance. The purpose of the present invention is to provide an inexpensive X-link lifting device that is narrow (the width of the cradle is small) between the X-links.
