図示実施例は上記の如く構成するものにして、以下、車両検査装置１を構成する各試験ローラ３…の取付け方法を説明する。 The illustrated embodiment is configured as described above, and a method for attaching the test rollers 3 constituting the vehicle inspection apparatus 1 will be described below.

先ず、図１、図２に示すように、複数の各試験ローラ３…を、装置本体２を構成するフレーム２ａのローラ配置部２Ａに取り付ける場合、図４、図５にも示すように、試験ローラ３の各軸部３ｂ，３ｂを、ローラ配置部２Ａに設けたフレーム２ａを構成する各軸支板２Ａａ，２Ａａの各溝部２Ａｃ，２Ａｃに沿って上方から挿入するとともに、各溝部２Ａｃ，２Ａｃから各孔部２Ａｂ，２Ａｂに対して挿入される斜め下方に向けて移動させ、各孔部２Ａｂ，２Ａｂ中心に挿入する。 First, as shown in FIGS. 1 and 2, when a plurality of test rollers 3 are attached to the roller arrangement portion 2A of the frame 2a constituting the apparatus main body 2, the test is performed as shown in FIGS. The shaft portions 3b and 3b of the roller 3 are inserted from above along the groove portions 2Ac and 2Ac of the shaft support plates 2Aa and 2Aa constituting the frame 2a provided in the roller arrangement portion 2A, and the groove portions 2Ac and 2Ac. To be moved obliquely downwardly inserted into the holes 2Ab and 2Ab and inserted into the centers of the holes 2Ab and 2Ab.

また、試験ローラ３の各軸部３ｂ，３ｂを上方から下方に向けて挿入するとき、各溝部２Ａｃ，２Ａｃの両側縁部に当接しながら移動し、各孔部２Ａｂ，２Ａｂに対して直接挿入されるのを防止し、挿入時に付与される衝撃を軽減する。 Further, when the shafts 3b and 3b of the test roller 3 are inserted from the upper side to the lower side, the shafts 3b and 3Ac move while being in contact with both side edges of the grooves 2Ac and 2Ac, and are directly inserted into the holes 2Ab and 2Ab. To reduce the impact applied during insertion.

次に、図６にも示すように、各軸支板２Ａａ，２Ａａの各孔部２Ａｂ，２Ａｂ中心に突出する試験ローラ３の各軸部３ｂ，３ｂを、各孔部２Ａｂ，２Ａｂの内周縁部に対して外側から嵌合される各軸受体２Ａｄ，２Ａｄの中心部に挿入し、各軸受体２Ａｄ，２Ａｄを、各孔部２Ａｂ，２Ａｂの外側縁部に形成した各取付け孔２Ａｅ…に対して複数の各ボルト２Ａｆ…により一体的に固定して軸受する。また、残りの各試験ローラ３…は、上述と同様にしてローラ配置部２Ａに取り付ける。 Next, as shown in FIG. 6, the shaft portions 3b and 3b of the test roller 3 protruding from the centers of the holes 2Ab and 2Ab of the shaft support plates 2Aa and 2Aa are connected to the inner peripheral edges of the holes 2Ab and 2Ab. Is inserted into the center of each bearing body 2Ad, 2Ad fitted from the outside to the mounting portion, and each bearing body 2Ad, 2Ad is inserted into each mounting hole 2Ae ... formed in the outer edge of each hole 2Ab, 2Ab. On the other hand, the bearings are integrally fixed by a plurality of bolts 2Af. The remaining test rollers 3 are attached to the roller arrangement portion 2A in the same manner as described above.

また、軸支板２Ａａの孔部２Ａｂに対して溝部２Ａｃが偏心しているので、試験ローラ３の軸部３ｂを下方から上方に向けて移動するとき、孔部２Ａｂの内周縁部に一旦当接して、略真上方向に対して直接的な移動及び抜取りが防止される。 Further, since the groove 2Ac is eccentric with respect to the hole 2Ab of the shaft support plate 2Aa, when the shaft 3b of the test roller 3 is moved upward from below, it is temporarily brought into contact with the inner peripheral edge of the hole 2Ab. Therefore, direct movement and extraction with respect to the substantially upward direction are prevented.

一方、各試験ローラ３…を、装置本体２のローラ配置部２Ａから取り外す場合、各ボルト２Ａｆ…による固定を解除して、各軸受体２Ａｄ，２Ａｄを各軸支板２Ａａ，２Ａａの各孔部２Ａｂ，２Ａｂから取り外すとともに、試験ローラ３の各軸部３ｂ，３ｂを、各孔部２Ａｂ，２Ａｂから取り外される各軸受体２Ａｄ，２Ａｄから抜き取る。この後、試験ローラ３の各軸部３ｂ，３ｂを、各孔部２Ａｂ，２Ａｂから各溝部２Ａｃ，２Ａｃに挿入される斜め上方に向けて移動させ、各溝部２Ａｃ，２Ａｃに挿入された試験ローラ３の各軸部３ｂ，３ｂを略真上方向に移動させると、試験ローラ３の各軸部３ｂ，３ｂを各軸支板２Ａａ，２Ａａの各孔部２Ａｂ，２Ａｂから抜き取ることができ、試験ローラ３の交換、メンテナンス等の作業が行える。また、残りの各試験ローラ３…は、上述と同様にしてローラ配置部２Ａから取り外す。 On the other hand, when the test rollers 3 are removed from the roller arrangement portion 2A of the apparatus main body 2, the fixing by the bolts 2Af is released, and the bearing bodies 2Ad, 2Ad are connected to the holes of the shaft support plates 2Aa, 2Aa. While removing from 2Ab and 2Ab, each shaft part 3b and 3b of the test roller 3 is extracted from each bearing body 2Ad and 2Ad removed from each hole 2Ab and 2Ab. Thereafter, the shaft portions 3b, 3b of the test roller 3 are moved obliquely upward from the holes 2Ab, 2Ab and inserted into the grooves 2Ac, 2Ac, and the test rollers inserted into the grooves 2Ac, 2Ac. When the shaft portions 3b and 3b of FIG. 3 are moved substantially directly upward, the shaft portions 3b and 3b of the test roller 3 can be extracted from the hole portions 2Ab and 2Ab of the shaft support plates 2Aa and 2Aa. Operations such as replacement and maintenance of the roller 3 can be performed. Further, the remaining test rollers 3 are removed from the roller placement portion 2A in the same manner as described above.

また、各軸支板２Ａａ，２Ａａの各溝部２Ａｃ，２Ａｃは、各孔部２Ａｂ，２Ａｂの中心に対して偏心させているので、試験ローラ３の各軸部３ｂ，３ｂを略真上方向に移動させたとき、各軸部３ｂ，３ｂの外周面が各孔部２Ａｂ，２Ａｂの内周縁部に当接し、略真上方向への移動及び抜取りを阻止する。 Further, since the groove portions 2Ac, 2Ac of the shaft support plates 2Aa, 2Aa are eccentric with respect to the centers of the holes 2Ab, 2Ab, the shaft portions 3b, 3b of the test roller 3 are substantially upward. When moved, the outer peripheral surfaces of the shaft portions 3b, 3b come into contact with the inner peripheral edge portions of the hole portions 2Ab, 2Ab to prevent the movement and extraction in the substantially upward direction.

且つ、上記試験ローラ３と同様にして、左右に配列した後部試験ローラ３，３を連結する中間軸８の両端軸部８ａ，８ａを、中間軸８の両端軸部８ａ，８ａが軸支される間隔に隔てて配置した各軸支板２Ａａ，２Ａａの各孔部２Ａｂ，２Ａｂに対して各溝部２Ａｃ，２Ａｃから挿入して、各軸支板２Ａａ，２Ａａに固定される各制動力検出装置６，６により軸受する。また、中間軸８の軸部８ａを、孔部２Ａｂに固定される軸受体２Ａｄで回転可能に軸受してもよい。 In the same manner as the test roller 3, both end shaft portions 8a and 8a of the intermediate shaft 8 connecting the rear test rollers 3 and 3 arranged on the left and right are supported by the both end shaft portions 8a and 8a of the intermediate shaft 8. Each braking force detection device is inserted into each hole 2Ac, 2Ac with respect to each hole 2Ab, 2Ab of each shaft support plate 2Aa, 2Aa arranged at an interval, and fixed to each shaft support plate 2Aa, 2Aa. Bearing with 6,6. Further, the shaft portion 8a of the intermediate shaft 8 may be rotatably supported by a bearing body 2Ad fixed to the hole portion 2Ab.

以上のように、試験ローラ３の両端部に突設した各軸部３ｂ，３ｂ又は中間軸８の両端軸部８ａ，８ａを、装置本体２を構成するフレーム２ａの各軸支板２Ａａ…の各孔部２Ａｂ…に上方から挿入し、各孔部２Ａｂ…に固定される各軸受体２Ａｄ…により軸受するので、軸受体２Ａｄが固定される枠状又は台状の取付け部を装置本体２内に設ける必要がなく、取付け部よりも軸支板２Ａａの方が薄く、軸支に必要な強度が得られるので、装置全体の構成及び構造を簡素化することができる。且つ、取付け部の寸法と対応する高さだけ装置全体が嵩低くなり、薄型化が図れる。 As described above, the shaft portions 3b, 3b projecting from both ends of the test roller 3 or the shaft portions 8a, 8a of the intermediate shaft 8 are connected to the shaft support plates 2Aa of the frame 2a constituting the apparatus main body 2. Since the bearings 2Ad are inserted into the holes 2Ab from above and are fixed to the holes 2Ab, the frame-like or base-like mounting parts to which the bearings 2Ad are fixed are provided in the apparatus main body 2. The shaft support plate 2Aa is thinner than the mounting portion, and the strength required for the shaft support can be obtained. Therefore, the configuration and structure of the entire apparatus can be simplified. In addition, the entire apparatus is reduced in volume by a height corresponding to the dimension of the mounting portion, and the thickness can be reduced.

また、試験場内の床部に設けた凹状据付け部に設置する場合、薄型の車両検査装置１を設置する凹状据付け部の深さが浅くて済み、施工作業が短期間で行えるとともに、施工費の低減を図ることができる。また、車両検査装置１の前後部に緩やかスロープを設置すれば、略平坦な据付け面に水平設置することも可能であり、設置場所の状況に応じて設置方法を選択することもできる。 Moreover, when installing in the concave installation part provided in the floor part in a test site, the depth of the concave installation part which installs the thin vehicle inspection apparatus 1 may be shallow, and construction work can be done in a short period of time, and construction cost Reduction can be achieved. Moreover, if a gentle slope is installed in the front and rear portions of the vehicle inspection apparatus 1, it is possible to horizontally install on a substantially flat installation surface, and an installation method can be selected according to the situation of the installation location.

また、試験ローラ３の各軸部３ｂ，３ｂを、各軸支板２Ａａ，２Ａａの各溝部２Ａｃ，２Ａｃに沿って上方から挿入して軸受するか、各軸支板２Ａａ，２Ａａの各溝部２Ａｃ，２Ａｃに沿って上方に抜き取り分離するので、装置本体に対する試験ローラ３の取外し作業や取付け作業が簡単且つ容易に行える。 Further, the shaft portions 3b and 3b of the test roller 3 are inserted and supported from above along the groove portions 2Ac and 2Ac of the shaft support plates 2Aa and 2Aa, respectively, or the groove portions 2Ac of the shaft support plates 2Aa and 2Aa. , 2Ac and extracted upward and separated, the detaching work and mounting work of the test roller 3 from the apparatus main body can be performed easily and easily.
