Then, the shaft hole ring 96 formed at the tip of the rod 95 at the other end of the first hydraulic cylinder 91 is fixed to the substantially central portion of the lower surface of the horizontal frame 43 of the crank boom 41 by welding or the like. A pair of trapezoidal protrusions 45 are provided, and a shaft hole 46 is formed at the center of the pair of trapezoidal protrusions 45. A shaft hole ring 96 at the tip of the rod 95 of the first hydraulic cylinder 91 is sandwiched between a pair of trapezoidal protrusions 45, 45 having the shaft hole 46, and the shaft 97 pivots freely. The supported vehicle wrecker device 40 is configured (see FIGS. 1 and 6). Each of the shafts 107 and 97 is prevented from coming off by a C-shaped retaining ring or the like (not shown).

レッカー装置40は、この様に、そのクランク形ブーム41の水平フレーム部43の左端軸穴44を、荷台22のサブフレーム23を成すサブフレーム横材B27上に溶接等で固着されているブラケット34の両端の曲げ起し部34aに穿設された軸穴34b、34bに挿通された軸34cにより枢支されている。更に、クランク形ブーム41を構成する水平フレーム部43の中間部の下面側を、左右のサブフレーム縦材25、24にボルト108とナット109とにより上端T字形取付部材101を取付けられ支持されている、略V字形の支持部材100の下端の略U字形曲げ部105の軸穴106に挿通されている軸107に回動可能に枢支されている第1の油圧シリンダ91のロッド95の軸穴リング96に挿通された軸97に回動可能に枢支されたクランク形ブーム41により構成されている。このクランク形ブーム41は荷台22を構成するサブフレーム23の低い位置で支持されているので、クランク形ブーム41には、高さ方向に発生するモーメントは小さい。   In this manner, the wrecker device 40 has a bracket 34 in which the left end shaft hole 44 of the horizontal frame portion 43 of the crank boom 41 is fixed to the subframe cross member B27 forming the subframe 23 of the loading platform 22 by welding or the like. These are pivotally supported by shafts 34c inserted into shaft holes 34b and 34b drilled in the bent raising portions 34a at both ends of the shaft. Further, an upper end T-shaped attachment member 101 is attached to and supported by the bolts 108 and nuts 109 on the left and right subframe vertical members 25 and 24 on the lower surface side of the intermediate portion of the horizontal frame portion 43 constituting the crank boom 41.

The crank boom 41 is pivotally supported by a shaft 97 inserted through the hole ring 96. Since the crank boom 41 is supported at a low position of the subframe 23 constituting the loading platform 22, the crank boom 41 has a small moment generated in the height direction.

このクランク形ブーム41を上記記載と重複するが詳述すると、L字形フレーム42(図1、図6において)と、このL字形フレーム42の下方端近傍部にて回動自在に軸54に枢支された後部フレーム65とにより構成されている。そして、このL字形フレーム42は、水平フレーム部43と、この水平フレーム部43と連続して下方に延在する垂直フレーム部50とより成る。この水平フレーム部43は中空であり、前端部44の前端部軸穴44aをブラケット34と軸34cとにより回動自在に枢支されており、水平フレーム部43の下面略中央部に溶接等により固着された一対の台形状の突出部45を設け、この台形状の突出部45の中央部に軸穴46が穿設されている。この軸穴46を有する一対の台形状の突出部45、45の間に、第1の油圧シリンダ91のロッド95の先端部の軸穴リング96を挟持して軸97にて回動可能に枢支されている(図1、図6参照)。そして、水平フレーム部43の右方には、軸穴47が穿通され、軸62が、この軸穴47を貫き、更に、延在する軸62は、内部空間に配置された第2の油圧シリンダ55のシリンダ本体56の突部57に設けられた軸穴58を中間に貫き支えて、更に、向こう側の軸穴47に挿通されている。もちろん、軸62は、図示しないC形止め輪等の抜け止めが施されている。   This crank-shaped boom 41 overlaps with the above description, but will be described in detail. An L-shaped frame 42 (in FIGS. 1 and 6) and a shaft 54 that is pivotable in the vicinity of the lower end of the L-shaped frame 42 are pivoted. The rear frame 65 is supported. The L-shaped frame 42 includes a horizontal frame portion 43 and a vertical frame portion 50 that extends continuously downward from the horizontal frame portion 43. The horizontal frame portion 43 is hollow, and the front end portion shaft hole 44a of the front end portion 44 is pivotally supported by the bracket 34 and the shaft 34c. The horizontal frame portion 43 is welded to a substantially central portion of the lower surface of the horizontal frame portion 43 by welding or the like. A pair of fixed trapezoidal protrusions 45 are provided, and a shaft hole 46 is formed in the center of the trapezoidal protrusion 45. A shaft hole ring 96 at the tip of the rod 95 of the first hydraulic cylinder 91 is sandwiched between a pair of trapezoidal protrusions 45, 45 having the shaft hole 46 so as to be pivotable by a shaft 97. It is supported (see FIGS. 1 and 6). A shaft hole 47 is penetrated to the right of the horizontal frame portion 43, the shaft 62 penetrates the shaft hole 47, and the extending shaft 62 is a second hydraulic cylinder disposed in the internal space. The shaft hole 58 provided in the protrusion 57 of the cylinder body 56 of 55 is penetrated and supported in the middle, and is further inserted through the shaft hole 47 on the far side. Of course, the shaft 62 is provided with a stopper such as a C-shaped retaining ring (not shown).

そして、水平フレーム部43に連続して下方に延在する垂直フレーム部50の下端部51には下端開口部51aが設けられていて(これにより第2油圧シリンダが緩衝されずに作動できる。)、下端近傍に軸穴53が貫通している。この軸穴53を中心に後端面と下端面とを繋いで下方端円弧部52で右隅を切欠いた状態に形成されている。外フレーム部材71を挟持し、且つ、溶接等により固着されている一対の略三角形状の支持部材66の先端部に設けられた第一の軸穴67を、垂直フレーム部50の軸穴53に外側から重ね合せて軸54を貫通させて、L字形フレーム42の下端部51に後部フレーム65が回動自在に枢支されている。即ち、この軸54を中心に後部フレーム65が、下方端円弧部52に沿って起立収納状態(図1矢印H方向二点鎖線状態)と、車両牽引時の倒伏状態(図1の矢印G方向の実線状態)とに回動自在に装着されている。   And the lower end part 51a of the vertical frame part 50 extended continuously below the horizontal frame part 43 is provided with the lower end opening part 51a (this can operate | move without buffering a 2nd hydraulic cylinder). The shaft hole 53 penetrates near the lower end. The rear end surface and the lower end surface are connected to each other with the shaft hole 53 as a center, and the lower end circular arc portion 52 is formed so that the right corner is notched. A first shaft hole 67 provided at the distal end portion of a pair of substantially triangular support members 66 sandwiching the outer frame member 71 and fixed by welding or the like is formed in the shaft hole 53 of the vertical frame portion 50. The rear frame 65 is pivotally supported by the lower end portion 51 of the L-shaped frame 42 so as to overlap with each other from the outside and penetrate the shaft 54. That is, the rear frame 65 centered on the shaft 54 is stowed and stowed along the lower end arc portion 52 (a state indicated by a two-dot chain line in FIG. 1 arrow H) and a lying state when the vehicle is pulled (in the direction indicated by an arrow G in FIG. 1). (Solid line state) is rotatably mounted.

そして、この後部フレーム65は、前端部にて一対の略三角形状の支持部材66が挟持して固着されている外フレーム部材71の後方開口端71aに嵌入して入れ子式を成す内フレーム部材72を有している。これ等の外フレーム部材71と内フレーム部材72との間にはポリアミド樹脂(ナイロン)板等耐磨耗性良好、且つ、耐熱性良好の合成樹脂の潤滑材を配置して滑らかな摺動を確保している。そして、前端部にて一対の略三角形状の支持部材66により挟持され固着されている外フレーム部材71は、第一の軸穴67の右下方に第2の軸穴68を、更に、その右方に第3の軸穴69を夫々穿設し、この第2の軸穴68には、軸63が挿通され、そして延在する軸63は外フレーム部材71の内部で、第2の油圧シリンダ55のロッド59の軸穴リング60をも挿通し、向こう側の第2の軸穴68に挿通している。そして前記のように第2の油圧シリンダ55のシリンダ本体56の突部57に設けられた軸穴58は、L字形フレーム42の水平フレーム部43の右方軸穴47に挿通された軸62に回動可能に軸支されているために、後述するようにレッカー装置操作部110の操作レバーB112により作動する第2の油圧シリンダ55のために、軸54を中心に後部フレーム65が、下方端円弧部52に沿って起立収納状態と、車両牽引時の倒伏状態とを回動自在に行える。   The rear frame 65 is inserted into the rear opening end 71a of the outer frame member 71 to which a pair of substantially triangular support members 66 are sandwiched and fixed at the front end portion, and the inner frame member 72 is nested. have. Between these outer frame member 71 and inner frame member 72, a synthetic resin lubricant having good wear resistance and good heat resistance such as a polyamide resin (nylon) plate is arranged for smooth sliding. Secured. Then, the outer frame member 71 sandwiched and fixed by the pair of substantially triangular support members 66 at the front end portion has a second shaft hole 68 at the lower right of the first shaft hole 67 and further to the right. A third shaft hole 69 is bored in each direction, a shaft 63 is inserted into the second shaft hole 68, and the extending shaft 63 is disposed inside the outer frame member 71, in the second hydraulic cylinder. The shaft hole ring 60 of the rod 59 of 55 is also inserted through the second shaft hole 68 on the far side. As described above, the shaft hole 58 provided in the protrusion 57 of the cylinder body 56 of the second hydraulic cylinder 55 is connected to the shaft 62 inserted through the right shaft hole 47 of the horizontal frame portion 43 of the L-shaped frame 42. Since the second hydraulic cylinder 55 is actuated by the operation lever B112 of the tow device operation unit 110 as will be described later, the rear frame 65 is centered on the shaft 54 and has a lower end. A standing storage state and a lying state when towing the vehicle can be rotated along the arc portion 52.

更に、外フレーム部材71に入れ子式に摺動自在に設けられている内フレーム部材72の中間部に、軸穴73が穿設されている。外フレーム部材71の第3の軸穴69に挿通され、更に延在した軸87により、外フレーム部在71の内部にて第3の油圧シリンダ81のシリンダ本体82の突部83に穿たれた軸穴84をも回動可能に枢支され、向こう側の第3の軸穴69に挿通されている。第3の油圧シリンダ81のロッド85の軸穴リング86は、内フレーム部材72の内部にて、軸穴73,73に挿通された軸88の中間部に回動可能に枢支されている。これにより後述するようにレッカー装置操作部110の操作レバーC113により作動する第3の油圧シリンダ81のために、外フレーム部材71に入れ子式に摺動自在に設けられている内フレーム部材72が可動範囲内において、必要とされる任意の位置に伸縮自在に操作可能である。なお、軸54、軸63、軸87、軸88は、各々図示しないC形止め輪等で抜け止めが施されているものとする。   Further, a shaft hole 73 is formed in an intermediate portion of the inner frame member 72 that is slidably provided in the outer frame member 71. The shaft 87 inserted through the third shaft hole 69 of the outer frame member 71 and further extended was bored in the protrusion 83 of the cylinder body 82 of the third hydraulic cylinder 81 inside the outer frame portion 71. The shaft hole 84 is also pivotably supported, and is inserted into the third shaft hole 69 on the far side. The shaft hole ring 86 of the rod 85 of the third hydraulic cylinder 81 is pivotally supported in the middle portion of the shaft 88 inserted through the shaft holes 73, 73 inside the inner frame member 72. As a result, the inner frame member 72 that is slidably provided in the outer frame member 71 in a slidable manner is movable for the third hydraulic cylinder 81 that is operated by the operation lever C113 of the tow device operation unit 110, as will be described later. Within the range, it can be extended and retracted to any required position. It is assumed that the shaft 54, the shaft 63, the shaft 87, and the shaft 88 are each prevented from coming off by a C-shaped retaining ring or the like (not shown).

そして、図1中の拡大斜視図を参照すると、内フレーム部材72の後端部の部品取付部75は、上下の舌片75aに軸穴75bを有するボス部75cが支持されている。この軸穴75bに、外側から連結部材76の取付部76bに穿通されている軸穴76cが重ねられて、軸77が挿通されて、この軸77のピン穴77aに割りピン78が挿入されて抜け止めが図られている。この連結部材76に被牽引車両130の前車軸133が載置されて、図示しない鎖やワイヤ等で固定されて前車軸133がずれないようになされて、牽引される。被牽引車両130がバス等で前車軸がない車両の場合は、この部品取付部75に連結部材76の代わりに前車輪を固定するフォーク部材(図示せず)等を使用すればよい。   Referring to the enlarged perspective view in FIG. 1, the component mounting portion 75 at the rear end of the inner frame member 72 is supported by a boss portion 75c having a shaft hole 75b in the upper and lower tongue pieces 75a. A shaft hole 76c that is penetrated from the outside into the mounting portion 76b of the connecting member 76 is overlaid on the shaft hole 75b, a shaft 77 is inserted, and a split pin 78 is inserted into the pin hole 77a of the shaft 77. The stopper is designed. The front axle 133 of the to-be-towed vehicle 130 is placed on the connecting member 76 and is fixed by a chain, a wire, or the like (not shown) so that the front axle 133 does not shift and is towed. In the case where the towed vehicle 130 is a bus or the like and does not have a front axle, a fork member (not shown) for fixing a front wheel may be used for the component mounting portion 75 instead of the connecting member 76.

次に、第1の油圧シリンダ91を支えている略V字形支持部材100についても重複部分があるが詳述する(図3、図6参照)。クランク形ブーム41の水平フレーム部43の下面略中央部に溶接等により固着された一対の台形状で中央部に軸穴46を有する突出部45の間に、第1の油圧シリンダ91のロッド95先端部の軸穴リング96を挟持して軸97にて回動自在に枢支されている(図1、図6参照)ことは前述した。そして、第1の油圧シリンダ91のシリンダ本体92の突部93の軸穴94は、略V字形支持部材100の軸穴106、106間に軸107にて回動可能に枢支されている。   Next, the substantially V-shaped support member 100 that supports the first hydraulic cylinder 91 will also be described in detail although there is an overlapping portion (see FIGS. 3 and 6). The rod 95 of the first hydraulic cylinder 91 is interposed between a pair of trapezoidal shapes that are fixed to the substantially central portion of the lower surface of the horizontal frame portion 43 of the crank boom 41 by welding or the like and having a shaft hole 46 in the central portion. As described above, the shaft hole ring 96 at the front end portion is sandwiched and pivotally supported by the shaft 97 (see FIGS. 1 and 6). The shaft hole 94 of the protrusion 93 of the cylinder body 92 of the first hydraulic cylinder 91 is pivotally supported by the shaft 107 between the shaft holes 106 and 106 of the substantially V-shaped support member 100.

即ち、図1、図2、図3を参照して、メインフレーム縦材右4とメインフレーム縦材左5に載置されたサブフレーム縦材右24とサブフレーム縦材左25に、略V字形支持部材100の左右において(特に図3参照)、上端T字形取付部101が左右合計12個所のボルト穴103により、スペーサを介してボルト108とナット109とで取付けられている。   That is, with reference to FIGS. 1, 2 and 3, the subframe vertical member right 24 and the subframe vertical member left 25 placed on the main frame vertical member right 4 and the main frame vertical member left 5 are substantially V On the left and right sides of the letter-shaped support member 100 (see in particular FIG. 3), the upper end T-shaped attachment part 101 is attached by bolts 108 and nuts 109 via spacers through a total of twelve bolt holes 103 on the left and right.

略V字形支持部材100において、下端の略U字形曲げ部105を形成し、ここの左右に軸穴106,106を穿通し、この軸穴106の一方から軸107を挿通し、中間に第1の油圧シリンダ91のシリンダ本体92の突部93の軸穴94を回動可能に枢支し、反対側の軸穴106に挿通させ、軸107の両端部には図示しないがC形止め輪や割ピン等の抜け止めを施せばよい。略V字形支持部材100は、下端の略U字形曲げ部105の上方にてV字状に広がって、上端T字形取付部101を形成し、片側で縦方向に3個ずつ前後2列のボルト穴103を計6個、左右両側で合計12個のボルト穴103を配置している。この上端T字形取付部101を、ミゾ形鋼のサブフレーム縦材右24とミゾ形鋼のサブフレーム縦材左25のミゾの中へ各々スペーサ102を当てはめてから外側からボルト108を合計12本を挿通し、ナット109を使用して、サブフレーム縦材右24とサブフレーム縦材左25とに取付けられる。この場合に、略V字形支持部材100がレッカー車両1のエンジン(図示せず)からの動力を後輪に伝えるための後車軸12の減速・差動装置用ハウジング13に干渉しない後方の近い位置に垂下近設されている(図1では後車輪16の左右の後車輪16a,16bの中心に近設されているとも言える。)。   In the substantially V-shaped support member 100, a substantially U-shaped bent portion 105 at the lower end is formed, shaft holes 106 and 106 are pierced on the left and right sides thereof, a shaft 107 is inserted from one of the shaft holes 106, and the first is in the middle. The shaft hole 94 of the projection 93 of the cylinder main body 92 of the hydraulic cylinder 91 is pivotally supported and inserted into the shaft hole 106 on the opposite side. What is necessary is just to give retaining pins, such as a split pin. The substantially V-shaped support member 100 spreads in a V shape above the substantially U-shaped bent portion 105 at the lower end to form an upper end T-shaped mounting portion 101, and two bolts in the front and rear in three rows in the longitudinal direction on one side. There are a total of six holes 103, a total of twelve bolt holes 103 on the left and right sides. The upper end T-shaped mounting portion 101 is inserted into the grooves of right groove 24 of the grooved steel subframe vertical member 24 and left groove 25 of the grooved steel subframe vertical member 25, respectively, and then a total of 12 bolts 108 are provided from the outside. And is attached to the subframe vertical member right 24 and the subframe vertical member left 25 using the nut 109. In this case, the substantially V-shaped support member 100 is located close to the rear so as not to interfere with the reduction / differential device housing 13 of the rear axle 12 for transmitting power from the engine (not shown) of the tow truck 1 to the rear wheels. (In FIG. 1, it can be said that it is located near the center of the left and right rear wheels 16a, 16b of the rear wheel 16.)

これにより略V字形支持部材100の上端T字形取付部101がサブフレーム23にとりつけられていて、第1の油圧シリンダ91の下端部であるシリンダ本体92の突部93の軸穴94を、軸107により略V字形支持部材100の下端の略U字形曲げ部105に回動可能に枢支されており、そして、第1の油圧シリンダ91のロッド95先端部の軸穴リング96を、荷台22のサブフレーム横材B27に固着されたブラケット34に、左端を回動自在に枢支されたクランク形ブーム41の、水平フレーム部43の下面略中央部に溶接等により固着された一対の台形状で中央部に軸穴46を有する突出部45の間に、第1の油圧シリンダ91のロッド95先端部の軸穴リング96を挟持され、軸97にて回動自在に枢支されている。ここでレッカー装置40のレッカー装置操作部110の操作レバーA111の操作により、L字形フレーム42と後部フレーム65とを有するクランク形ブーム41が、可動範囲内であるが、必要とされる任意の位置に上下上昇降下を垂直面内に自在に操作可能となる。 As a result, the upper end T-shaped mounting portion 101 of the substantially V-shaped support member 100 is attached to the subframe 23, and the shaft hole 94 of the protrusion 93 of the cylinder body 92, which is the lower end portion of the first hydraulic cylinder 91, is 107 is pivotally supported by a substantially U-shaped bent portion 105 at the lower end of the substantially V-shaped support member 100, and the shaft hole ring 96 at the tip of the rod 95 of the first hydraulic cylinder 91 is connected to the loading platform 22. A pair of trapezoidal shapes fixed by welding or the like to a substantially central portion of the lower surface of the horizontal frame portion 43 of the crank-shaped boom 41 pivotally supported at the left end to the bracket 34 fixed to the subframe cross member B27. The shaft hole ring 96 at the tip of the rod 95 of the first hydraulic cylinder 91 is sandwiched between the projecting portions 45 having the shaft hole 46 at the center, and is pivotally supported by the shaft 97. Here, the crank-shaped boom 41 having the L-shaped frame 42 and the rear frame 65 is within the movable range by the operation of the operation lever A111 of the tow device operation unit 110 of the tow device 40, but any position that is required. In addition, it is possible to freely operate the vertical ascent and descent in the vertical plane.

そして、クランク形ブーム41をなすL字形フレーム42の水平フレーム部43の左端軸穴44を、荷台22のサブフレーム23を成すサブフレーム横材B27上に溶接等で固着されているブラケット34の両端の曲げ起し部34aに穿設された軸穴34b、34bに挿通された軸34cにより枢支し、更に、水平フレーム部43の中間部を、左右のサブフレーム縦材25、24にボルト108とナット109とにより取付け、下方の後車軸12の減速・差動装置ハウジング13の後方近傍であって、L字形フレーム42前方にまで垂下し設けられれた略V字形支持部材100の下端の略U字形曲げ部105の軸穴106に挿通されている軸107に支持されている第1の油圧シリンダ91に支えられたクランク形ブーム41により構成されている。第1の油圧シリンダ91を、下支えしている略V字形支持部材100が後車軸12の減速・差動装置用ハウジング13の後方に近設され、その後方にクランク形ブーム41をなすL字形フレーム42の垂直フレーム部50を、略V字形支持部材100の後方の近傍に配置できるので、水平フレーム部43を含んだL字形フレーム42の全長を短くすることができる。これにより、クランク形ブーム41は、全長を短くすることが出来ると共に荷台22を構成するサブフレーム23の低い位置で支持されているので、クランク形ブーム41には、水平方向、即ち、長さ方向に、発生するモーメントも、また、高さ方向に発生するモーメントも小さい。このような構成のためにレッカー車両1が比較的小型車両であっても、重量バランスが良好であるために、大型で大きい重量の被牽引車両130でも容易に牽引可能である。   The left end shaft hole 44 of the horizontal frame portion 43 of the L-shaped frame 42 forming the crank-shaped boom 41 is fixed to both ends of the bracket 34 fixed by welding or the like on the subframe cross member B27 forming the subframe 23 of the loading platform 22. Are pivotally supported by a shaft 34c inserted into shaft holes 34b and 34b formed in the bending raising portion 34a, and an intermediate portion of the horizontal frame portion 43 is connected to the left and right subframe vertical members 25 and 24 with bolts 108. And a nut 109. The lower U of the substantially V-shaped support member 100 is provided in the vicinity of the rear of the speed reduction / differential device housing 13 of the lower rear axle 12 and hanging forward to the front of the L-shaped frame 42. The crank-shaped boom 41 is supported by a first hydraulic cylinder 91 supported by a shaft 107 inserted through a shaft hole 106 of the character-shaped bending portion 105. There. An approximately V-shaped support member 100 that supports the first hydraulic cylinder 91 is provided close to the rear of the speed reduction / differential device housing 13 of the rear axle 12, and an L-shaped frame that forms a crank-shaped boom 41 at the rear thereof. Since the vertical frame part 50 of 42 can be arrange | positioned in the back vicinity of the substantially V-shaped support member 100, the full length of the L-shaped frame 42 containing the horizontal frame part 43 can be shortened. As a result, the crank boom 41 can be shortened in its overall length and is supported at a low position of the subframe 23 constituting the loading platform 22, so that the crank boom 41 has a horizontal direction, that is, a length direction. In addition, the moment generated and the moment generated in the height direction are small. Because of such a configuration, even if the tow truck 1 is a relatively small vehicle, the weight balance is good, so that the towed vehicle 130 having a large size and a large weight can be easily towed.

次に図4〜図10を参照して、車両用レッカー装置40を搭載したレッカー車両1による被牽引車両130を牽引する説明をする。初めに、図1に二点鎖線で示す起立収納状態の後部フレーム65を、図2、図3に示すレッカー装置操作部110の操作レバーB112により作動する第2の油圧シリンダ55のために、軸54を中心に後部フレーム65を回動させ、車両牽引時の倒伏状態とし、更に、操作レバーC113の操作により内フレーム部材72を第3の油圧シリンダ81のロッド85を少し伸長させておく。そして、図7、図4のように、レッカー装置40を搭載したレッカー車両1を牽引される車両130の前方に移動させる。(勿論、レッカー装置操作部110は、レッカー車両1のエンジン(図示せず)に駆動される油圧駆動回路により、作動制御される。)   Next, with reference to FIGS. 4 to 10, description will be given of towing the towed vehicle 130 by the tow truck 1 on which the tow device 40 for a vehicle is mounted. First, the rear frame 65 in the standing and stowed state shown by a two-dot chain line in FIG. 1 is used for the second hydraulic cylinder 55 operated by the operation lever B112 of the tow device operation unit 110 shown in FIGS. The rear frame 65 is rotated around the center of the vehicle 54 so as to be in a lying state when the vehicle is pulled, and the rod 85 of the third hydraulic cylinder 81 is slightly extended from the inner frame member 72 by operating the operation lever C113. Then, as shown in FIGS. 7 and 4, the tow truck 1 mounted with the tow device 40 is moved in front of the towed vehicle 130. (Of course, the tow device operation unit 110 is controlled by a hydraulic drive circuit driven by an engine (not shown) of the tow truck 1).

図8、図5のように、レッカー装置操作部110の操作レバーA111の操作により、クランク形ブーム41の前端部44の前端軸穴44aと軸34cとを中心に、クランク形ブーム41の先端の連結部材76を地面すれすれに下方に降下させる。図9に示すように、車両用レッカー装置40を搭載したレッカー車両1を少し後退させて、クランク形ブーム41の後方自由端の連結部材76を被牽引車両130の前車軸133の下方に押し込む(図8、図9参照)。そして、操作レバーC113の操作により内フレーム部材72を第3の油圧シリンダ81のロッド85を必要により伸縮させて、連結部材本体76aを被牽引車両130の前車軸133の直下に位置させる。次に操作レバーA111の操作によりクランク形ブーム41の後端の連結部材76の連結部材本体76aを被牽引車両130の前車軸133に下方から当接させ、ワイヤや鎖等(図示せず)を巻付けて、前車軸133と連結部材本体76aとを固定する。次に、図10、図6に示すように、操作レバーA111の操作により、クランク形ブーム41の前端部44の前端軸穴44aと軸34cとを中心に、クランク形ブーム41の後端の連結部材76の連結部材本体76aを上方に回動させ、被牽引車両130の前車軸133を路面18から所望の高さに持上げて、牽引可能状態とする。   As shown in FIGS. 8 and 5, the operation of the operation lever A111 of the tow device operation unit 110 causes the front end of the crank boom 41 to be centered around the front end shaft hole 44a and the shaft 34c of the front end 44 of the crank boom 41. The connecting member 76 is lowered below the ground. As shown in FIG. 9, the tow truck 1 mounted with the tow truck device 40 is slightly retracted, and the connecting member 76 at the free rear end of the crank boom 41 is pushed below the front axle 133 of the towed vehicle 130 ( (Refer FIG. 8, FIG. 9). Then, by operating the operation lever C113, the inner frame member 72 is expanded and contracted as required by the rod 85 of the third hydraulic cylinder 81, and the connecting member main body 76a is positioned directly below the front axle 133 of the towed vehicle 130. Next, by operating the operation lever A111, the connecting member main body 76a of the connecting member 76 at the rear end of the crank boom 41 is brought into contact with the front axle 133 of the towed vehicle 130 from below, and a wire, a chain or the like (not shown) is attached. It winds and the front axle 133 and the connection member main body 76a are fixed. Next, as shown in FIGS. 10 and 6, by connecting the rear end of the crank boom 41 around the front end shaft hole 44 a and the shaft 34 c of the front end 44 of the crank boom 41 by operating the operation lever A 111. The connecting member main body 76a of the member 76 is rotated upward, and the front axle 133 of the to-be-towed vehicle 130 is lifted from the road surface 18 to a desired height so that it can be pulled.

このような構成であるために、構造も単純で油圧シリンダーも第1、第2、第3の3個(引出線91、55、81)という必要最小限とし、レッカー装置操作部110の操作レバーもA,B,Cの3個(引出線111,112,113)であり、その操作も前方に押すか後方に引くかして簡単であり、被牽引車両130を傷付けるような構造でも無く、且つ、構成も簡素で安価に製造可能で、容易にレッカー車両1に搭載可能なレッカー装置40となる。   Because of this configuration, the structure is simple and the hydraulic cylinders are the first, second, and third (leader lines 91, 55, 81), which are the minimum necessary, and the operation lever of the tow device operation unit 110 is provided. Are also three (leader lines 111, 112, 113) of A, B, and C, and the operation is simple by pushing forward or pulling backward, and there is no structure that damages the towed vehicle 130, In addition, the tow device 40 is simple and can be manufactured at low cost, and can be easily mounted on the tow truck 1.

上述したように、本発明の車両用レッカー装置40によれば、構造も単純で油圧シリンダー(引出線番号91,55,81)も必要最小限の3個とし、そのために油圧シリンダの操作も3個の操作レバー(引出線番号111,112,113)を押すか引くかの簡単な操作で、被牽引車両130を傷付けることが無く、且つ、構造も簡素で、安価に製造可能で、容易にレッカー車両1に搭載可能なレッカー装置40である。しかもクランク形ブーム41を回動させるための第1の油圧シリンダ91を支持する略V字形支持部材100を後車軸12の後方に近設しているために、被牽引車両130の重量が加わるクランク形ブーム41を構成するL字形フレーム42の垂直フレーム部50を後車軸12に近づけられるため、水平フレーム部43を短くすることが出来、ひいてはクランク形ブーム41全体の長さを短く出来るために、比較的小型のレッカー車両1にレッカー装置40を搭載しても、重量大の被牽車両130の牽引が可能である。   As described above, according to the vehicle wrecker device 40 of the present invention, the structure is simple and the number of hydraulic cylinders (leader numbers 91, 55, 81) is set to a minimum of three. Simple operation of pushing or pulling the operation levers (leader numbers 111, 112, 113) does not damage the towed vehicle 130, has a simple structure, can be manufactured inexpensively, and easily This is a tow device 40 that can be mounted on the tow truck 1. In addition, since the substantially V-shaped support member 100 that supports the first hydraulic cylinder 91 for rotating the crank boom 41 is provided close to the rear of the rear axle 12, the crank to which the weight of the towed vehicle 130 is applied. Since the vertical frame portion 50 of the L-shaped frame 42 constituting the shaped boom 41 can be brought close to the rear axle 12, the horizontal frame portion 43 can be shortened, and consequently the overall length of the crank shaped boom 41 can be shortened. Even if the tow device 40 is mounted on a relatively small tow truck 1, the heavy towed vehicle 130 can be pulled.
