【０００７】[0007]
上記構成において、建設現場の走行通路が狭い場合や、走行途上に障害物があ る場合、または自走車を運搬車に積載して他の建設現場に運搬する場合には、ま ず第１のロック手段１０をロック解除状態にすると共に、第２のロック手段１１ により、自走車本体２または最大径筒フレーム部材７ｃと他方の走行支持枠６ｂ とを一体的に連結した状態で、油圧シリンダ９を収縮作動させることによって、 最小径及び中間径の両筒フレーム部材７ａ，７ｂを収縮させた後、最小径筒フレ ーム部材７ａと中間径筒フレーム部材７ｂとを第１のロック手段１０で一体的に 連結すればよい。これによって、一方の走行駆動部材１ａが内側に引き込まれ、 両走行駆動部材１ａ，１ｂ間の走行幅Ｌが狭められるため（図１及び図２参照） 、自走車を容易に移動させることができる。 In the above configuration, if the construction passage is narrow, there is an obstacle on the way, or the self-propelled vehicle is loaded on a carrier and transported to another construction site, first In the state in which the lock means 10 of 1 is unlocked and the second lock means 11 integrally connects the self-propelled vehicle main body 2 or the maximum-diameter tubular frame member 7c and the other traveling support frame 6b, After contracting the cylinder 9 to contract both the minimum diameter and intermediate diameter cylindrical frame members 7a and 7b, the minimum diameter cylindrical frame member 7a and the intermediate diameter cylindrical frame member 7b are locked by the first locking means. It suffices if they are integrally connected at 10. As a result, one of the traveling drive members 1a is pulled inward and the traveling width L between the traveling drive members 1a and 1b is narrowed (see FIGS. 1 and 2), so that the self-propelled vehicle can be easily moved. it can.
【０００８】 また、自走車本体２上に設けた建設機械４により大重量物を吊り上げる場合に は、まず第１のロック手段１０をロック解除状態にすると共に、第２のロック手 段１１により、自走車本体２または最大径筒フレーム部材７ｃと他方の走行支持 枠６ｂとを一体的に連結した状態で、油圧シリンダ９を伸長作動させることによ って、最小径及び中間径の両筒フレーム部材７ａ，７ｂを伸長させた後、その両 筒フレーム部材７ａ，７ｂを第１のロック手段１０で一体的に連結すればよい。 これによって、一方の走行駆動部材１ａが外側に張り出され、走行幅Ｌが拡げら れると共に、自走車本体２が他方の走行駆動部材１ａ側に偏り、自走車本体２の 中心Ｏから一方の走行駆動部材１ａの中心を通る転倒点Ｐまでの間隔Ｈを大きく とることができるため（図３及び図４参照）、大重量物の吊り上げ作業中に自走 車が横転する恐れがない。When a heavy load is to be hoisted by the construction machine 4 provided on the self-propelled vehicle body 2, first the first locking means 10 is unlocked and the second locking means 11 is used. By extending the hydraulic cylinder 9 while the self-propelled vehicle body 2 or the maximum-diameter tubular frame member 7c and the other traveling support frame 6b are integrally connected, both the minimum diameter and the intermediate diameter can be obtained. After extending the tubular frame members 7a and 7b, both tubular frame members 7a and 7b may be integrally connected by the first locking means 10. As a result, one traveling drive member 1a is projected to the outside and the traveling width L is expanded, and the vehicle body 2 is biased toward the other traveling drive member 1a side from the center O of the vehicle body 2. Since the distance H to the tipping point P passing through the center of one of the traveling drive members 1a can be made large (see FIGS. 3 and 4), there is no risk of the self-propelled vehicle overturning during the lifting work of heavy objects. .
【０００９】 更に、自走車本体２上に設けた建設機械４により一般的な建設作業を行う場合 には、上記のように走行幅Ｌを拡げ、第１のロック手段１０で最小径筒フレーム 部材７ａと中間径筒フレーム部材７ｂとを一体的に連結した後、第２のロック手 段１１のロック状態をを解除し、油圧シリンダ９を収縮作動させることによって 、自走車本体２を両走行駆動部材１ａ，１ｂ間の中間位置まで移動させ、上記第 ２のロック手段１１で自走車本体２または最大径筒フレーム部材７ｃと他方の走 行支持枠６ｂとを一体的に連結すればよい。これによって、自走車本体２が走行 幅Ｌを拡げた状態の両走行駆動部材１ａ，１ｂ間の中間に位置して安定的に支持 されるため（図５及び図６参照）、該自走車本体２を中心にその全周にわたって 安定した同じ条件で作業を行うことができる。Further, when general construction work is performed by the construction machine 4 provided on the self-propelled vehicle main body 2, the traveling width L is expanded as described above, and the first locking means 10 is used to form the minimum diameter tubular frame. After integrally connecting the member 7a and the intermediate-diameter tubular frame member 7b, the locked state of the second locking means 11 is released, and the hydraulic cylinder 9 is contracted to operate the self-propelled vehicle main body 2 in both directions. If it is moved to an intermediate position between the traveling drive members 1a and 1b and the second vehicle locking means 11 integrally connects the self-propelled vehicle body 2 or the maximum diameter tubular frame member 7c and the other traveling support frame 6b. Good. As a result, the self-propelled vehicle main body 2 is positioned in the middle between the traveling drive members 1a and 1b in a state where the traveling width L is expanded and is stably supported (see FIGS. 5 and 6). It is possible to work under the same stable condition over the entire circumference of the vehicle body 2.

【００１４】 走行幅Ｌを変換する場合の要領を説明すると、建設現場の走行通路が狭い場合 や、走行途上に障害物がある場合、または自走車を運搬車に積載して他の建設現 場に運搬する場合には、第１ロックボルト１３を取外すると共に、第２ロックボ ルト１８によりロック杆１７をロック板１６の基端部に連結する。これによって 、両走行支持枠６ａ，６ｂどうしの連結が解除されると共に、自走車本体２が他 方の走行支持枠６ｂに一体的に連結される。この状態で、油圧シリンダ９を収縮 作動させることによって、最小径筒フレーム部材７ａと中間径筒フレーム部材７ ｂとを収縮させた後、その両筒フレーム部材７ａ，７ｂを第１ロックボルト１３ で一体的に連結すればよい。これによって、図１及び図２に示すように、一方の 走行駆動部材１ａが内側に引き込まれ、両走行駆動部材１ａ，１ｂ間の走行幅Ｌ が狭められるため、自走車を容易に移動させることができる。The procedure for converting the traveling width L will be described. When the traveling passage at the construction site is narrow, there is an obstacle on the way of traveling, or the self-propelled vehicle is loaded on the transport vehicle and other construction is performed. For transportation to the field, the first lock bolt 13 is removed, and the lock rod 17 is connected to the base end portion of the lock plate 16 by the second lock bolt 18. As a result, the connection between the two traveling support frames 6a and 6b is released, and the vehicle body 2 is integrally connected to the other traveling support frame 6b. In this state, by contracting the hydraulic cylinder 9 to contract the minimum diameter tubular frame member 7a and the intermediate diameter tubular frame member 7b, both tubular frame members 7a and 7b are locked by the first lock bolt 13. It may be connected integrally. As a result, as shown in FIGS. 1 and 2, one of the traveling drive members 1a is pulled inward, and the traveling width L between the traveling drive members 1a and 1b is narrowed, so that the vehicle can be easily moved. be able to.

The minimum diameter cylindrical frame member 7a and the intermediate diameter cylindrical frame member 7b may be expanded by extending 9 and then both cylindrical frame members 7a and 7b may be integrally connected by the first lock bolt 13. As a result, as shown in FIG. 3 and FIG. 4, one traveling drive member 1a is projected outward, the traveling width L is expanded, and the vehicle body 2 is biased toward the other traveling drive member 1b side. Since the distance H from the center O 2 of the self-propelled vehicle main body 2 to the tipping point P passing through the center of the one traveling drive member 1a can be made large (see FIGS. 3 and 4), the lifting work of heavy weight objects can be performed. There is no risk of the self-propelled vehicle rolling over.
【００１６】 更に、自走車本体２上に設けた建設機械４により一般的な建設作業を行う場合 には、図３及び図４の状態から、第２ロックボルト１８を取外した後、油圧シリ ンダ９を収縮作動させることによって、自走車本体２を両走行駆動部材１ａ，１ ｂ間の中間位置まで移動させ、上記第２ロックボルト１８でロック杆１７をロッ ク板１６の先端部に連結すればよい。これによって、図５及び図６に示すように 、自走車本体２が走行幅Ｌを拡げた状態の両走行駆動部材１ａ，１ｂ間の中間に 位置して安定的に支持されるため、該自走車本体２を旋回させた場合でも、自走 車が横転する恐れがない。Further, when performing a general construction work by the construction machine 4 provided on the self-propelled vehicle body 2, after removing the second lock bolt 18 from the state of FIGS. 3 and 4, the hydraulic cylinder The vehicle body 2 is moved to an intermediate position between the traveling drive members 1a and 1b by contracting the binder 9, and the lock rod 17 is attached to the tip of the lock plate 16 by the second lock bolt 18. Just connect them. As a result, as shown in FIGS. 5 and 6, since the vehicle body 2 is positioned in the middle between the traveling drive members 1a and 1b in the state where the traveling width L is widened and is stably supported, Even if the self-propelled vehicle body 2 is turned, the self-propelled vehicle is not likely to roll over.
【００１７】 上記実施例では、油圧シリンダ９を、一方の走行支持枠６ａと自走車本体２と の間に設けると共に、該自走車本体２と他方の走行支持枠６ｂとを第２のロック 手段１１により一体的に連結するようにしたが、これ以外に、油圧シリンダ９を 、他方の走行支持枠６ｂと自走車本体２との間に設けると共に、該自走車本体２ と一方の走行支持枠６ａとを第２のロック手段１１により一体的に連結するよう にしてもよい。In the above-described embodiment, the hydraulic cylinder 9 is provided between the traveling support frame 6a on one side and the vehicle body 2 for traveling, and the traveling vehicle body 2 and the traveling support frame 6b on the other side are provided for the second. The hydraulic cylinder 9 is provided between the traveling support frame 6b on the other side and the self-propelled vehicle main body 2 and the self-propelled vehicle main body 2 and The traveling support frame 6a may be integrally connected by the second locking means 11.

本考案によれば、１本の油圧シリンダを作動させるだけで、走行幅と自走車本 体の幅方向の位置を容易に変換することができ、しかも三重合筒フレームによっ て自走車本体とその両側の走行支持枠とを連結するようにしたため、且つ上述の ように油圧シリンダ１本でよく、他の伸縮機構の障害となることがないため、走 行幅を広く取ることができ、より安定した現場作業に貢献することができる。 According to the present invention, the traveling width and the position of the vehicle body in the width direction can be easily changed by operating only one hydraulic cylinder, and furthermore, the vehicle body can be driven by the tri-polymer cylinder frame. Since the main body and the traveling support frames on both sides of the main body are connected to each other, and since only one hydraulic cylinder is required as described above, it does not interfere with the other expansion and contraction mechanism, the traveling width can be wide. , Can contribute to more stable field work.
