Description

本発明は、軌道レール上を走行し、概し、鉄道線路の保守点検のために現場への物品の搬送のために用いる台車に関するものである。 The present invention relates to a carriage that travels on a track rail and is generally used for transporting articles to the site for maintenance and inspection of railway tracks.

線路の保守点検のために物品を現場へ搬送する台車は、軌道上を走行する関係上、軌間の異なる軌道（線路）レールに合わせて用意する必要があり、従って、線路工事に関わる業者は、工事作業に際し、当該軌道レールを走行できるように配置した走行車輪を備えた台車を準備する必要がある。 The truck that transports goods to the site for track maintenance inspection needs to be prepared according to the track (track) rail with different gauges because of traveling on the track. In the construction work, it is necessary to prepare a cart provided with traveling wheels arranged so as to be able to travel on the track rail.

軌間の異なる軌道レールにそれぞれ対応する台車を準備するのは、その分、線路工事としての準備作業を必要とし、また、軌間の異なる種々の軌道レールに対応する台車を予め用意しておくのは、当該保管場所を必要とするのみならず、経費負担ともなる。 Preparing a truck corresponding to each track rail with different gauges requires preparation work corresponding to the track construction, and preparing a truck corresponding to various track rails with different gauges in advance , Not only the storage location is required, but also a cost burden.

基台の下面に互いに平行する前後一対の案内レールを装置し、該案内レールに沿って移動する一対の車輪体を各案内レールに配設し、該一対の車輪体の相対する側に一端を回動自在に接続した仲介片それぞれの他の一端を、前記基台に回動自在に枢支した連結片の端部に回動自在に接続すると共に、各車輪体には、相対して軌道レールを挟むフランジを備え、しかも、軌道レール上を走行する走行車輪を回動自在に軸支した構成としたものである。 A pair of front and rear guide rails parallel to each other are provided on the lower surface of the base, and a pair of wheel bodies that move along the guide rails are disposed on each guide rail, with one end on the opposite side of the pair of wheel bodies. The other end of each of the mediating pieces that are pivotally connected is pivotally connected to the end of a connecting piece that is pivotally supported by the base, and each wheel body is tracked relative to each other. It has a configuration in which a flange that sandwiches the rail is provided and a traveling wheel that travels on the track rail is pivotally supported.

本発明によれば、連結片とこれに回動自在に接続した仲介片が、いわばリンク機構を構成して各仲介片に接続した車輪体が互いに近接、離開し、該近接、離開の程度が、走行車輪の軌道レールの軌間として現われ、走行車輪は当該軌間に追従して軌道レール上を走行することができ、従って、軌間の異なる或いは、軌間が広狭変化する軌道レールに対応した台車を提供することができる。 According to the present invention, the connecting piece and the mediating piece pivotally connected to the connecting piece constitute a link mechanism so that the wheel bodies connected to the mediating pieces are brought close to and separated from each other, and the degree of the approaching and separating is set. , Appearing as a track rail of the running wheel, the running wheel can follow the track and travel on the track rail, thus providing a truck corresponding to the track rail with different or different width can do.

図中、１は台車Ａの基台で、基台１は、形鋼で成る方形枠状の補強枠１ｂ上に物品を載せる主体板１ａを重ね合せて止着して成り、補強枠１ｂを構成する前、後枠の下面に前、後の案内レール２，２´を熔接して互いに平行させて配置したものである。 In the figure, reference numeral 1 denotes a base of the carriage A. The base 1 is formed by stacking and fixing a main plate 1a on which an article is placed on a square frame-shaped reinforcing frame 1b made of steel. Before the construction, the front and rear guide rails 2 and 2 'are welded to the lower surface of the rear frame and arranged parallel to each other.

各案内レール２，２´には一対の車輪体３，３を配設し、車輪体３，３は、前記案内レール２，２´に沿って移動して互いに近接又は離開するようにリンク機構４を介して互いに連結してある。 A pair of wheel bodies 3, 3 are arranged on each guide rail 2, 2 ′, and the wheel bodies 3, 3 move along the guide rails 2, 2 ′ so as to approach or separate from each other. 4 are connected to each other via 4.

また、車輪体３は、一対の相対する第一支持板５ａ，５ａと、他の一対の相対する第二支持板５ｂ，５ｂを互いに直交方向に配して構成した車輪枠５の、前記第二支持板５ｂ，５ｂを介する前記第一支持板５ａ，５ａの両側に案内ローラを６を、前記第一支持板５ａ，５ａを介する前記第二支持板５ｂ，５ｂの両側に走行車輪７をそれぞれ回動自在に枢着して成るもので、案内レール２，２´の下端側の頭部２ａ，２´ａに前記第一支持板５ａの両側に設けた掛止部片８間に介在させるようにして、前記の通り、各案内レール２，２´を配し、案内レール２，２´のそれぞれに一対の前記車輪体３，３を組合わせ、該車輪体３，３同士が隣接する側の前記第二支持板５ｂの中央に部片９を突設し、該部片９に前記リンク機構４の端部を接続して、前記の通り、各案内レール２，２´毎に一対の車輪体３，３を装置したものである。 The wheel body 3 includes a wheel frame 5 having a pair of opposed first support plates 5a and 5a and another pair of opposed second support plates 5b and 5b arranged in an orthogonal direction. Guide rollers 6 are provided on both sides of the first support plates 5a and 5a via the two support plates 5b and 5b, and traveling wheels 7 are provided on both sides of the second support plates 5b and 5b via the first support plates 5a and 5a. These are pivotally attached to each other, and are interposed between the latching piece pieces 8 provided on both sides of the first support plate 5a on the heads 2a, 2'a on the lower end side of the guide rails 2, 2 '. As described above, the guide rails 2 and 2 'are arranged as described above, and the pair of wheel bodies 3 and 3 are combined with each of the guide rails 2 and 2', and the wheel bodies 3 and 3 are adjacent to each other. A piece 9 is projected from the center of the second support plate 5b on the side to be connected, and the end of the link mechanism 4 is connected to the piece 9 As described above, in which the apparatus a pair of wheels 3, 3 for each guide rail 2,2'.

リンク機構４は、前記案内レール２，２´の長手方向の中央部に吊設した支持杆１０に、中央部において回動自在に組付けた連結片１１の端部にそれぞれ仲介片１２の一端を回動自在に接続し、仲介片１２の他の一端を前記部片９に回動自在に枢着して構成したものである。 The link mechanism 4 has one end of an intermediate piece 12 on the end of a connecting piece 11 that is rotatably mounted on a support rod 10 suspended in the center in the longitudinal direction of the guide rails 2 and 2 '. And the other end of the mediating piece 12 is pivotally attached to the part piece 9.

連結片１１を支持杆１０を中心にして回動させるように外力を負荷すると、各案内レール２，２´に組合わせた、それぞれ一対の車輪体３，３は案内レール２，２´に沿って移動し、軌道レール１３，１３の軌間に一致するように、互いに近接又は離開し、軌道レール１３を車輪体３の走行車輪７が転動、走行し、台車の軌道レール１３に沿った移動が円滑に行われる。 When an external force is applied so that the connecting piece 11 is rotated about the support rod 10, the pair of wheel bodies 3, 3 combined with the guide rails 2, 2 'are along the guide rails 2, 2'. And move close to or apart from each other so as to coincide with the rails of the track rails 13, 13, and the traveling wheel 7 of the wheel body 3 rolls and travels on the track rail 13, and moves along the track rail 13 of the carriage. Is done smoothly.

なお、実施例の案内ローラ６および走行車輪７は、それぞれ相対するフランジ６ａ，６ａ、７ａ，７ａを備え、該フランジ６ａ，６ａ、７ａ，７ａで案内レール２，２´若しくは軌道レール１３を挟み、所謂脱輪を防ぐようにしてある。 The guide roller 6 and the traveling wheel 7 of the embodiment are provided with flanges 6a, 6a, 7a, 7a that face each other, and the guide rails 2, 2 'or the track rail 13 are sandwiched between the flanges 6a, 6a, 7a, 7a. In other words, so-called derailment is prevented.

しかして、当該軌道レール１３，１３の軌間部の各レール１３上に走行車輪７を載せるようにすると、支持杆１０を中心にして連結片１１が回動して、すなわち、リンク機構４が機能して相対する走行車輪７，７は当該軌間部のレール１３上に載置され、この台車Ａを軌道レール１３上に載せた状態で、基台１を軌道レール１３の長手方向に沿う方向に適宜の手段で押圧或いは牽引すると、レール１３上を走行車輪が転動し、台車Ａ（基台１）は軌道レール１３に沿って移動する。 Thus, when the traveling wheels 7 are placed on the rails 13 of the rail portions of the track rails 13 and 13, the connecting piece 11 rotates around the support rod 10, that is, the link mechanism 4 functions. Thus, the opposed traveling wheels 7 and 7 are placed on the rail 13 of the rail portion, and the base 1 is placed in a direction along the longitudinal direction of the track rail 13 with the carriage A placed on the track rail 13. When pressed or pulled by an appropriate means, the traveling wheel rolls on the rail 13, and the carriage A (base 1) moves along the track rail 13.

そして、この移動中、軌間が広狭変化する軌道であっても、該広狭の変化に対応して仲介片１２に連けいした連結片１１は回動し、走行車輪７は広狭変化に追従して軌道レール１３上を走行し、台車Ａの移動が円滑に行われる。 During this movement, even if the trajectory changes in width between the gauges, the connecting piece 11 connected to the mediating piece 12 rotates corresponding to the change in width, and the traveling wheel 7 follows the change in width. The vehicle travels on the rail 13 and the carriage A moves smoothly.
