従来、タイヤとリムを組付けたタイヤ・リム組立体を車両等の車軸に脱着する 作業において、その作業を補助するものとして、例えば、実開平２− 38202号の ものが知られているが、これは、固定台座の四隅にガイドバーを立設して、この ガイドバーに、ローラー付タイヤ載置台を上下動自在に取付け、テコバーによっ てタイヤ載置台を上下動させる構造のものであった。 Conventionally, in the work of attaching and detaching a tire / rim assembly in which a tire and a rim are assembled to an axle of a vehicle or the like, for example, a work of Japanese Utility Model Laid-Open No. 2-32022 is known to assist the work. This had a structure in which guide bars were erected at the four corners of a fixed pedestal, a tire mounting table with rollers was attached to the guide bars so that it could move up and down, and a lever was used to move the tire mounting table up and down. .
【０００３】[0003]
しかし、このような構造のものでは、タイヤ・リム組立体を運搬することがで きず、しかも、テコバーの操作は人力によるものであるため、車軸に対するタイ ヤ・リム組立体の位置調整が困難で、脱着に手間がかかり、作業者への負担が大 きくなる問題があった。 However, with such a structure, the tire / rim assembly cannot be transported, and since the lever is operated manually, it is difficult to adjust the position of the tire / rim assembly with respect to the axle. However, there was a problem that it took a lot of time to attach and detach, and the burden on the operator became large.
【０００４】 そこで、本考案は従来のこのような問題点を解決して、タイヤ・リム組立体を 所望位置まで運搬可能で、人力にたよらず簡単に、タイヤ・リム組立体の上下左 右の位置決めができるタイヤ脱着補助台車を提供することを目的とする。Therefore, the present invention solves the above-mentioned problems of the related art, and the tire / rim assembly can be transported to a desired position. It is an object of the present invention to provide a tire attachment / detachment auxiliary cart that can be positioned.
【０００５】[0005]
本考案は、上記目的を達成するために、鉛直状支持枠部を有すると共に車輪を 備えた基枠と、該支持枠部に上下スライド自在に取付けられて上下に駆動される 昇降部材と、該昇降部材に左右スライド自在に取付けられて左右に駆動されるタ イヤ載置部材と、を備えたものである。 In order to achieve the above object, the present invention provides a base frame having a vertical support frame portion and wheels, an elevating member vertically slidably mounted on the support frame portion and driven vertically. And a tire mounting member that is slidably attached to the elevating member and is driven to the left and right.

【００２０】 また、上下駆動機構Ｍを、図４に示す如く構成してもよい。即ち、図４では、 上下駆動機構Ｍは、チェーン等の動力伝達部材14と、支持枠部１の下端部に回転 自在に枢支されたスプロケット等の回転子15と、竪枠部13，13の上部に取付プレ ート16を介して取付けられたモータ等の回転駆動機17と、回転駆動機17の出力軸 に取付けられたスプロケット等の回転子18と、からなる。Further, the vertical drive mechanism M may be configured as shown in FIG. That is, in FIG. 4, the vertical drive mechanism M includes a power transmission member 14 such as a chain, a rotor 15 such as a sprocket that is rotatably supported at a lower end of the support frame 1, and vertical frames 13 and 13. A rotary drive 17 such as a motor mounted on the upper part of the rotary plate via a mounting plate 16 and a rotor 18 such as a sprocket mounted on the output shaft of the rotary drive 17.
【００２１】 動力伝達部材14は、その両端部が昇降部材３に取付けられると共に、上下の回 転子18，15に噛合又は懸架され、回転駆動機17の駆動により昇降部材３が、左右 の竪枠部13，13に沿って上下する。Both ends of the power transmission member 14 are attached to the elevating member 3, and are engaged or suspended by the upper and lower rotors 18 and 15, and the elevating member 3 is driven by a rotary drive 17 so that the right and left vertical members are moved vertically. It goes up and down along the frame parts 13, 13.
【００２２】 この場合も、回転駆動機17は、図示省略の電源及び操作スイッチ等に接続され 、昇降部材３を所望高さに昇降・停止させることができる。In this case as well, the rotary drive 17 is connected to a power source, an operation switch, and the like, not shown, so that the elevating member 3 can be moved up and down to a desired height and stopped.
【００２３】 なお、図示省略するが、上下駆動機構Ｍとして、ピニオンとこれに噛合する左 右一対のラックを用い、該ラックを左右の竪枠部13，13に取付け、上記ピニオン を昇降部材３に回転自在に枢支して、回転駆動機で回転させ、昇降部材３を昇降 させるも自由である。Although not shown in the drawings, a pinion and a pair of left and right racks meshing with the pinion are used as the vertical drive mechanism M, the racks are attached to the left and right vertical frame portions 13 and 13, and the pinion is moved up and down.

It includes a female screw portion 20 to be fitted and a handle 21 for rotating the screw shaft 19.
【００２６】 このハンドル21を手動で回転させると、タイヤ載置部材４を、昇降部材３に沿 って、左右に所望量移動させることができる。なお、スクリューシャフト19を、 図示省略の電源及び操作スイッチ等に接続されたモータ等の回転駆動機で回転さ せるように構成するも自由である。By manually rotating the handle 21, the tire mounting member 4 can be moved left and right along the elevating member 3 by a desired amount. The screw shaft 19 may be freely rotated by a rotary drive machine such as a motor connected to a power source and operation switches (not shown).
【００２７】 しかして、上述の如く構成されたタイヤ脱着補助台車の使用方法を説明する。A method of using the tire attachment / detachment auxiliary truck configured as described above will be described.
【００２８】 まず、図１に示すように、タイヤ・リム組立体10を地面22等に鉛直状に載置し て、支持ローラー９，９を地面22に近接するまで下げた状態とし、タイヤ脱着補 助台車Ｒを前進させて、タイヤ・リム組立体10の接地面側のトレッド部11と地面 22との間に、左右の支持ローラー９，９を挿入する。First, as shown in FIG. 1, the tire / rim assembly 10 is placed vertically on the ground 22 and the like, and the support rollers 9 and 9 are lowered until they are close to the ground 22, and the tire is removed. The auxiliary cart R is moved forward to insert the left and right support rollers 9 between the tread portion 11 on the ground contact surface side of the tire / rim assembly 10 and the ground 22.
【００２９】 そして、昇降部材３を上昇させれば、図２に示すように、支持ローラー９，９ に、タイヤ・リム組立体10が鉛直状に支持される。When the elevating member 3 is raised, the tire / rim assembly 10 is vertically supported by the support rollers 9 and 9 as shown in FIG.
【００３０】 従って、タイヤ・リム組立体10を、別個に、人力等で持ち上げて支持ローラー ９，９に載置する必要がなく、簡単かつ迅速に、タイヤ・リム組立体10をタイヤ 載置部材４に載置でき、手間がかからない。Therefore, it is not necessary to separately lift the tire / rim assembly 10 manually and place it on the support rollers 9, 9, and the tire / rim assembly 10 can be easily and quickly mounted on the tire mounting member. It can be placed on 4 and does not take much time.
【００３１】 次に、タイヤ・リム組立体10を鉛直状に載置したままで台車Ｒを移動させて、 タイヤ取付場所までタイヤ・リム組立体10を運搬する。Next, the truck R is moved with the tire / rim assembly 10 placed vertically, and the tire / rim assembly 10 is transported to the tire mounting location.
【００３２】 そして、台車Ｒを位置決めして、図６に示すように、車両等の車軸23の位置と 、車軸23に嵌合するタイヤ・リム組立体10のリムディスク孔24の位置を、大まか に合わせる。Then, the carriage R is positioned so that the position of the axle 23 of the vehicle and the position of the rim disc hole 24 of the tire / rim assembly 10 fitted to the axle 23 are roughly determined as shown in FIG. To match.
【００３３】 さらに、車軸23とリムディスク孔24との上下位置ずれ量Ｈ及び左右位置ずれ量 Ｗだけ、支持ローラー９，９に鉛直状に支持されたタイヤ・リム組立体10を、上 記上下駆動機構Ｍ及び左右駆動機構Ｓ（図３及び図５参照）にて、上下左右に移 動させて位置調整を行う。ここで、Ｏ1 はリムディスク孔24の軸心，Ｏ2 は車軸 23の軸心である。Further, the tire / rim assembly 10 vertically supported by the support rollers 9 and 9 by the vertical displacement amount H and the horizontal displacement amount W between the axle shaft 23 and the rim disc hole 24 is moved up and down as described above. The drive mechanism M and the left-right drive mechanism S (see FIGS. 3 and 5) are moved vertically and horizontally to adjust the position. Here, O 1 is the axis of the rim disc hole 24, and O 2 is the axis of the axle 23.
【００３４】 次に、支持ローラー９，９上で、タイヤ・リム組立体10を回転させて、車軸23 の取付ボルト25…の位置と、タイヤ・リム組立体10のリムボルト孔26…の位置を 合わせた後、車軸23にリムディスク孔24を嵌め込み、取付ボルト25…にナットを 螺着してタイヤ・リム組立体10を取付ける。Next, by rotating the tire / rim assembly 10 on the support rollers 9 and 9, the positions of the mounting bolts 25 of the axle 23 and the positions of the rim bolt holes 26 of the tire / rim assembly 10 are adjusted. After the adjustment, the rim disc hole 24 is fitted into the axle 23, and the nut is screwed onto the mounting bolts 25, and the tire / rim assembly 10 is mounted.
【００３５】 また、タイヤ・リム組立体10を車軸23から取り外す場合は、上述と逆の手順で 作業を行えばよい。When the tire / rim assembly 10 is removed from the axle 23, the work may be performed in the reverse order of the above.
【００３６】 なお、本考案は上述の実施例に限定されず、本考案の要旨を逸脱しない範囲で 設計変更自由であり、例えば、タイヤ載置部材４の支持ローラー９，９の相互間 隔を調整可能に構成するも自由である。The present invention is not limited to the above-described embodiment, and the design can be freely changed without departing from the scope of the present invention. For example, the support rollers 9, 9 of the tire mounting member 4 may be separated from each other. It is also freely configurable to be adjustable.
【００３７】[0037]
本考案は上述の如く構成されているので、次に記載するような著大な効果を奏 する。 Since the present invention is constructed as described above, it has a great effect as described below.
【００３８】 タイヤ・リム組立体10を載せて所望位置まで運搬可能で、タイヤ・リム組立体 10を鉛直状に支持した状態で、昇降部材３及びタイヤ載置部材４を介して、人力 にたよらず簡単に、タイヤ・リム組立体10の上下左右の位置調整を行うことがで きる。The tire / rim assembly 10 can be placed and transported to a desired position, and with the tire / rim assembly 10 supported vertically, the lifting / lowering member 3 and the tire mounting member 4 can be used to manually move the tire / rim assembly 10. Therefore, the position adjustment of the tire / rim assembly 10 can be easily performed in the vertical and horizontal directions.
【００３９】 従って、本考案のタイヤ脱着補助台車を用いれば、車両等へのタイヤ・リム組 立体10の脱着作業が容易となり、作業者の負担が軽減される。Therefore, by using the tire attachment / detachment auxiliary truck of the present invention, the work of attaching / detaching the tire / rim assembly 10 to / from the vehicle or the like can be facilitated, and the burden on the operator is reduced.
