Description

本発明は、車両搭載型クレーンに使用される旋回ポストに関する。   The present invention relates to a swivel post used in a vehicle-mounted crane.

従来、ブームを有した作業車に使用される旋回ポストとして、例えば特許文献１に示される旋回ポストが提案されている。   Conventionally, as a turning post used for a work vehicle having a boom, for example, a turning post shown in Patent Document 1 has been proposed.

この旋回ポストは、ブームを有した作業車の旋回台上に設けられた底板部と、底板部上の車両左右側から上方に延びて設けられた一対の側板部とを備えている。一対の側板部は、上部が下部よりも側板部間の間隔が広くなるように形成されている。これにより、ブームの長尺化に際して強度を高めるためにブームの幅を大きくしても、このブームの基端部を取り付ける支持軸を側板部間に配置させることが可能になっている。   The turning post includes a bottom plate portion provided on a turntable of a work vehicle having a boom, and a pair of side plate portions provided to extend upward from the left and right sides of the vehicle on the bottom plate portion. The pair of side plate portions is formed such that the upper portion has a wider interval between the side plate portions than the lower portion. Thereby, even if the width of the boom is increased to increase the strength when the boom is lengthened, the support shaft to which the base end portion of the boom is attached can be disposed between the side plate portions.

特許第３６１６７０４号公報Japanese Patent No. 3616704

しかしながら特許文献１の旋回ポストは、一対の側板部の各々が、四方が板で囲まれた中空の柱状体で形成されていることから全体的に大型化している。   However, the swivel post of Patent Document 1 is entirely enlarged because each of the pair of side plate portions is formed of a hollow columnar body surrounded by a plate on all four sides.

本発明は、このような従来の課題に鑑みてなされたものであり、ブームの幅を大きくしても大型化を抑えることができる車両搭載型クレーン用旋回ポストを提供することを目的とする。   The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a vehicle-mounted crane turning post capable of suppressing an increase in size even if the width of a boom is increased.

本発明者等は、鋭意研究の結果、前記課題を解決するために以下のような車両搭載型クレーン用旋回ポストを採用した。   As a result of diligent research, the present inventors have adopted the following vehicle-mounted crane swivel post in order to solve the above problems.

本発明の車両搭載型クレーン用旋回ポストは、車両搭載型クレーンの旋回台上に設けられた底板部と、前記底板部上の車両左右側から上方に延びて設けられた一対の側板部とを備え、前記一対の側板部は、各々が平板状に形成され、上部が下部よりも側板部間の間隔が広くなるように形成されていることを特徴とする。   The turning post for a vehicle-mounted crane according to the present invention includes a bottom plate portion provided on a turntable of the vehicle-mounted crane and a pair of side plate portions provided to extend upward from the left and right sides of the vehicle on the bottom plate portion. The pair of side plate portions are each formed in a flat plate shape, and the upper portion is formed so that the interval between the side plate portions is wider than the lower portion.

また、本発明の車両搭載型クレーン用旋回ポストにおいて、前記上部で前記側板部間にブームの基端部を取り付ける支持軸が配置される部分が前記下部よりも前記側板部間の間隔が広くなるように形成されていることが好ましい。   Further, in the vehicle-mounted crane turning post according to the present invention, a portion where the support shaft for attaching the base end portion of the boom is disposed between the side plate portions at the upper portion has a wider interval between the side plate portions than the lower portion. It is preferable to be formed as described above.

また、本発明の車両搭載型クレーン用旋回ポストにおいて、前記上部で前記側板部間にウインチドラムが配置される部分が前記下部よりも前記側板部間の間隔が広くなるように形成されていることが好ましい。   Further, in the vehicle-mounted crane swivel post according to the present invention, a portion where the winch drum is disposed between the side plate portions in the upper portion is formed so that a distance between the side plate portions is wider than the lower portion. Is preferred.

本発明の車両搭載型クレーン用旋回ポストでは、一対の側板部の各々を平板状に形成し、上部が下部よりも側板部間の間隔が広くなるように形成した。これにより、一対の側板部が柱状体で形成されている場合に比べて一対の側板部の全体幅を抑えることが可能になる。よって、本発明の車両搭載型クレーン用旋回ポストは、ブームの幅を大きくしても大型化を抑えることができる。   In the vehicle-mounted crane turning post of the present invention, each of the pair of side plate portions is formed in a flat plate shape, and the upper portion is formed so that the interval between the side plate portions is wider than the lower portion. Thereby, compared with the case where a pair of side plate part is formed with the columnar body, it becomes possible to suppress the whole width of a pair of side plate part. Therefore, the vehicle-mounted crane swivel post of the present invention can suppress an increase in size even if the width of the boom is increased.

また、本発明の車両搭載型クレーン用旋回ポストでは、一対の側板部の上部で側板部間にブームの基端部を取り付ける支持軸が配置される部分が下部よりも側板部間の間隔が広くなるように形成することで、支持軸を所望の位置に確実に配置することが可能になる。よって、本発明の車両搭載型クレーン用旋回ポストは、ブームの幅を大きくしても大型化を抑えつつブームを所望の位置に確実に配置することができる。   Further, in the vehicle-mounted crane turning post of the present invention, the portion where the support shaft for attaching the base end portion of the boom is disposed between the side plate portions at the upper portion of the pair of side plate portions is wider than the lower portion. By forming so, the support shaft can be reliably arranged at a desired position. Therefore, the vehicle-mounted crane turning post according to the present invention can reliably arrange the boom at a desired position while suppressing an increase in size even if the width of the boom is increased.

また、本発明の車両搭載型クレーン用旋回ポストでは、一対の側板部の上部で側板部間にウインチドラムが配置される部分が下部よりも側板部間の間隔が広くなるように形成されることで、ウインチドラムの幅を大きくしても、側板部間にウインチドラムを容易に配置することが可能になる。これによりブームの長尺化及びフックの掛け数の増加に伴ってワイヤの巻き取り量が多くなっても、幅を大きくしたウインチドラムを配置することでワイヤの巻き取り層数を抑えることができる。よって、本発明の車両搭載型クレーン用旋回ポストは、ワイヤの巻き取り量が多くなっても、ワイヤの巻き取り性の低下やワイヤの食い込みを防ぐことができる。   In the vehicle-mounted crane turning post according to the present invention, the portion where the winch drum is disposed between the side plate portions at the upper portion of the pair of side plate portions is formed so that the interval between the side plate portions is wider than the lower portion. Thus, even if the width of the winch drum is increased, the winch drum can be easily disposed between the side plate portions. As a result, even if the winding amount of the wire increases as the length of the boom increases and the number of hooks increases, the number of winding layers of the wire can be suppressed by arranging a winch drum having a larger width. . Therefore, the turning post for a vehicle-mounted crane according to the present invention can prevent the wire winding performance from being lowered and the wire biting in even if the amount of wire winding increases.

以下、本発明の実施の形態を図にしたがって説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本発明の一実施の形態の車両搭載型クレーン用旋回ポスト５が適用された車両搭載型クレーン１の左側面図である。以下の説明では、車両搭載型クレーン１を単にクレーン１と称する。また車両搭載型クレーン用旋回ポスト５を単に旋回ポスト５と称する。   FIG. 1 is a left side view of a vehicle-mounted crane 1 to which a vehicle-mounted crane turning post 5 according to an embodiment of the present invention is applied. In the following description, the vehicle-mounted crane 1 is simply referred to as a crane 1. Further, the turning post 5 for a vehicle-mounted crane is simply referred to as a turning post 5.

最初にクレーン１の全体的な構成を簡単に説明する。このクレーン１は、走行機能を有する車体２と、車体２の前側左右に設けられたアウトリガ３と、車体２に水平旋回可能に取り付けられた旋回台４と、旋回台４上に立設された本実施の形態の旋回ポスト５と、旋回ポスト５に起伏自在に取り付けられたブーム６とを備えている。   First, the overall configuration of the crane 1 will be briefly described. This crane 1 is installed on the swivel base 4, a car body 2 having a traveling function, an outrigger 3 provided on the front left and right of the car body 2, a swivel base 4 attached to the car body 2 so as to be horizontally turnable. The swivel post 5 according to the present embodiment and a boom 6 attached to the swivel post 5 so as to be raised and lowered are provided.

アウトリガ３は、クレーン１の転倒を防止するものであり、油圧によって張出・接地が行われる。   The outrigger 3 prevents the crane 1 from overturning, and is extended and grounded by hydraulic pressure.

旋回台４は、車体２上に設けられた旋回駆動装置（図示せず）によってブーム６と一体に旋回駆動される。   The swivel base 4 is swiveled together with the boom 6 by a swivel drive device (not shown) provided on the vehicle body 2.

ブーム６は、基端ブーム６ａと中間ブーム６ｂ〜６ｃと先端ブーム６ｄとによって入れ子式に構成されており、伸縮シリンダ（図示せず）によって伸縮駆動される。   The boom 6 is configured to be nested by a base end boom 6a, intermediate booms 6b to 6c, and a distal end boom 6d, and is extended and retracted by an extendable cylinder (not shown).

基端ブーム６ａは、その付け根において旋回ポスト５に水平に設置された支持軸１０（図２参照）に回動自在に取り付けられており、上下に起伏できるようになっている。旋回ポスト５と基端ブーム６ａの基端部との間には起伏シリンダ１１が架け渡されており、この起伏シリンダ１１が伸縮することでブーム６全体が起伏駆動される。   The base end boom 6a is rotatably attached to a support shaft 10 (see FIG. 2) installed horizontally on the swivel post 5 at the base thereof, and can be raised and lowered up and down. A hoisting cylinder 11 is bridged between the swivel post 5 and the base end portion of the base end boom 6a, and the hoisting cylinder 11 is extended and contracted to drive the boom 6 as a whole.

先端ブーム６ｄの先端には回転自在のシーブ（図示せず）が取付けられており、このシーブにはワイヤ１２が掛けられている。ワイヤ１２の先端にはフックブロック１３を介してフック１４が取付けられている。ワイヤ１２の末端はウインチドラム１５に巻き掛けられている。   A rotatable sheave (not shown) is attached to the tip of the tip boom 6d, and a wire 12 is hung on the sheave. A hook 14 is attached to the tip of the wire 12 via a hook block 13. The end of the wire 12 is wound around a winch drum 15.

このウインチドラム１５は、図２に示すように旋回ポスト５内に回転自在に配置されている。このウインチドラム１５は、旋回ポスト５の外側に設けられた減速機１６を介して旋回ポスト５内に設けられたウインチモータ（図示せず）により回転駆動する。このウインチモータが巻き上げ方向又は巻き下げ方向に回転すると、減速機１６がその回転数を減じてウインチドラム１５に動力を伝達する。これによりウインチドラム１５は巻き上げ方向又は巻き下げ方向に回転駆動してワイヤ１２が巻き上げ又は巻き下げられ、これによりフック１４が引き上げ又は下げられる。   The winch drum 15 is rotatably arranged in the swivel post 5 as shown in FIG. The winch drum 15 is rotationally driven by a winch motor (not shown) provided in the turning post 5 via a reduction gear 16 provided outside the turning post 5. When the winch motor rotates in the winding direction or the lowering direction, the speed reducer 16 reduces the number of rotations and transmits power to the winch drum 15. Accordingly, the winch drum 15 is rotationally driven in the winding direction or the lowering direction, and the wire 12 is wound or lowered, and thereby the hook 14 is raised or lowered.

また、車体２には、コントローラ（図示せず）が設けられている。このコントローラは、吊り上げ作業に関する操作を行うために使用される。具体的にこのコントローラは、旋回レバー、伸縮操作レバー、起伏操作レバー、ウインチ操作レバー、アウトリガの張出・格納の操作スイッチ等を備えている。これらの操作レバーや操作スイッチを操作することで旋回駆動装置、伸縮シリンダ、起伏シリンダ１１、ウインチドラム１５及びウインチモータ、アウトリガ３の操作を行う。   The vehicle body 2 is provided with a controller (not shown). This controller is used to perform operations related to the lifting work. Specifically, this controller includes a turning lever, a telescopic operation lever, a hoisting operation lever, a winch operation lever, an outrigger extension / retraction operation switch, and the like. By operating these operation levers and operation switches, the turning drive device, the telescopic cylinder, the hoisting cylinder 11, the winch drum 15, the winch motor, and the outrigger 3 are operated.

次に、本実施の形態の旋回ポスト５の構成を説明する。   Next, the structure of the turning post 5 of the present embodiment will be described.

図２は、旋回ポスト５を車両後方側から視た斜視図である。この旋回ポスト５は、旋回台４（図１参照）上に設けられた底板部５１と、底板部５１上に上方に延びて設けられた支持部５２と、支持部５２の前側（車両後方側）に設けられた前板部５３とを備えている。   FIG. 2 is a perspective view of the turning post 5 viewed from the vehicle rear side. The turning post 5 includes a bottom plate portion 51 provided on the turntable 4 (see FIG. 1), a support portion 52 provided extending upward on the bottom plate portion 51, and a front side (vehicle rear side) of the support portion 52. ) Provided on the front plate portion 53.

（底板部５１）
底板部５１は平板状に形成されている。この底板部５１は旋回台４の上面に固定されている。底板部５１の上面において前板部５３の前側には、起伏シリンダ１１の下端を取り付ける一対の取付部１７，１７が設けられている。(Bottom plate portion 51)
The bottom plate portion 51 is formed in a flat plate shape. The bottom plate portion 51 is fixed to the upper surface of the turntable 4. A pair of attachment portions 17 for attaching the lower end of the undulation cylinder 11 is provided on the front side of the front plate portion 53 on the upper surface of the bottom plate portion 51.

（支持部５２）
支持部５２は、上記で説明したブーム６の基端部（基端ブーム６ａの基端部）を取り付ける支持軸１０とウインチドラム１５を支持するものである。この支持部５２は、前方側（車両後方側）が開口した形状に形成されている。(Supporting part 52)
The support portion 52 supports the support shaft 10 and the winch drum 15 to which the base end portion of the boom 6 described above (the base end portion of the base end boom 6a) is attached. The support portion 52 is formed in a shape having an opening on the front side (vehicle rear side).

この支持部５２は、図２と図３に示すように、底板部５１上の車両左右側から上方に延びて設けられた一対の側板部５２１，５２１と、一対の側板部５２１，５２１の後端（車両前方側端）を結合する後板部５２２とを備えている。   2 and 3, the support portion 52 includes a pair of side plate portions 521 and 521 provided on the bottom plate portion 51 so as to extend upward from the left and right sides of the vehicle, and a rear side of the pair of side plate portions 521 and 521. And a rear plate portion 522 that joins the ends (vehicle front side ends).

（一対の側板部５２１，５２１）
一対の側板部５２１，５２１は、図２に示すように、各々が一枚板により平板状に形成されている。さらに一対の側板部５２１，５２１は、上部５２１１，５２１１間の間隔Ｗ１が下部５２１３，５２１３間の間隔Ｗ３よりも広くなるように形成されている。これについて以下に具体的に説明する。(A pair of side plate portions 521 and 521)
As shown in FIG. 2, each of the pair of side plate portions 521 and 521 is formed in a flat plate shape by a single plate. Further, the pair of side plate portions 521 and 521 are formed such that the interval W1 between the upper portions 5211 and 5211 is wider than the interval W3 between the lower portions 5213 and 5213. This will be specifically described below.

一対の側板部５２１，５２１の下部５２１３，５２１３は、底板部５１の上面から上方に垂直に延びて形成されている。   Lower portions 5213 and 5213 of the pair of side plate portions 521 and 521 are formed to extend vertically upward from the upper surface of the bottom plate portion 51.

一対の側板部５２１，５２１の中間部５２１２，５２１２は、下部５２１３，５２１３の上端からさらに車両左右側へ斜め上方に延びる斜板部５２１２ｂ，５２１２ｂと、斜板部５２１２ｂ，５２１２ｂの上端から上方に垂直に延びる垂直板部５２１２ａ，５２１２ａとを備えている。   The intermediate portions 5212 and 5212 of the pair of side plate portions 521 and 521 extend upward from the upper ends of the swash plate portions 5212b and 5212b and the swash plate portions 5212b and 5212b extending obliquely upward from the upper ends of the lower portions 5213 and 5213 to the left and right sides of the vehicle.

The space S is provided with the winch motor (not shown) described above.

次に、本実施の形態の旋回ポスト５の効果を列挙して説明する。   Next, effects of the swivel post 5 according to the present embodiment will be listed and described.

（１）本実施の形態の旋回ポスト５は、車両搭載型クレーン１の旋回台４上に設けられた底板部５１と、底板部５１上の車両左右側から上方に延びて設けられた一対の側板部５２１，５２１とを備え、一対の側板部５２１，５２１は、各々が平板状に形成され、上部５２１１，５２１１が下部５２１３，５２１３よりも側板部５２１，５２１間の間隔Ｗ１が広くなるように形成されている。 (1) The turning post 5 according to the present embodiment includes a bottom plate portion 51 provided on the turntable 4 of the vehicle-mounted crane 1 and a pair of upper plates provided extending upward from the left and right sides of the vehicle on the bottom plate portion 51. Each of the pair of side plate portions 521 and 521 is formed in a flat plate shape, and the interval W1 between the side plate portions 521 and 521 is wider in the upper portions 5211 and 5211 than in the lower portions 5213 and 5213. Is formed.

これにより一対の側板部５２１，５２１は、各々四方が板で囲まれた中空の柱状体で形成されている場合に比べて一対の側板部５２１，５２１の全体幅を抑えることが可能になる。よって、本実施の形態の旋回ポスト５は、ブーム６の長尺化に際して強度を高めるためにブーム６の幅を大きくしても大型化を抑えることができる。   Thereby, the pair of side plate portions 521 and 521 can suppress the entire width of the pair of side plate portions 521 and 521 as compared to a case where each of the pair of side plate portions 521 and 521 is formed of a hollow columnar body surrounded by a plate on each side. Therefore, even if the width of the boom 6 is increased in order to increase the strength of the swivel post 5 of the present embodiment when the boom 6 is lengthened, the enlargement can be suppressed.

さらに本実施の形態の旋回ポスト５では、側板部５２１，５２１の下部５２１３，５２１３の構造は変わらないので、旋回装置を構成する旋回ベアリングや旋回外輪ボルトの配置を変更しなくても良い。   Further, in the turning post 5 of the present embodiment, the structures of the lower portions 5213 and 5213 of the side plate portions 521 and 521 are not changed, so that the arrangement of the turning bearing and the turning outer ring bolt constituting the turning device need not be changed.

（２）また、本実施の形態の旋回ポスト５では、側板部５２１，５２１の上部５２１１，５２１１で側板部５２１，５２１間にブーム６の基端部を取り付ける支持軸１０が配置される部分（支持軸配置部５２１１ａ）が、下部５２１３よりも側板部５２１，５２１間の間隔Ｗ１が広くなるように形成されている。 (2) Further, in the swivel post 5 of the present embodiment, the support shaft 10 for attaching the base end portion of the boom 6 between the side plate portions 521 and 521 at the upper portions 5211 and 5211 of the side plate portions 521 and 521 ( The support shaft arrangement portion 5211a) is formed so that the interval W1 between the side plate portions 521 and 521 is wider than the lower portion 5213.

これにより支持軸１０を所望の位置に確実に配置することが可能になる。よって、本実施の形態の旋回ポスト５は、ブーム６の幅を大きくしても大型化を抑えつつブーム６を所望の位置に確実に配置することができる。   As a result, the support shaft 10 can be reliably arranged at a desired position. Therefore, the swing post 5 of the present embodiment can reliably arrange the boom 6 at a desired position while suppressing an increase in size even if the width of the boom 6 is increased.

（３）また、本実施の形態の旋回ポスト５では、側板部５２１，５２１の上部５２１１，５２１１で側板部５２１，５２１間にウインチドラム１５が配置される部分（ウインチドラム配置部５２１１ｂ）が、下部５２１３，５２１３よりも側板部５２１，５２１間の間隔Ｗ１が広くなるように形成されている。 (3) Further, in the swivel post 5 of the present embodiment, the portion (winch drum arrangement portion 5211b) where the winch drum 15 is arranged between the side plate portions 521 and 521 at the upper portions 5211 and 5211 of the side plate portions 521 and 521, The space W1 between the side plate portions 521 and 521 is formed to be wider than the lower portions 5213 and 5213.

これによりウインチドラム１５の幅（胴部１５ａの幅）を大きくしても、側板部５２１，５２１間にウインチドラム１５を容易に配置することが可能になる。そのため、ブーム６の長尺化及びフック１４の掛け数の増加に伴ってワイヤ１２の巻き取り量が多くなっても、幅を大きくしたウインチドラム１５を配置することでワイヤ１２の巻き取り層数を抑えることができる。よって、本実施の形態の旋回ポスト５は、ワイヤ１２の巻き取り量が多くなっても、ワイヤ１２の巻き取り性の低下やワイヤ１２の食い込みを防ぐことができる。   Accordingly, even if the width of the winch drum 15 (the width of the body portion 15a) is increased, the winch drum 15 can be easily disposed between the side plate portions 521 and 521. Therefore, even if the winding amount of the wire 12 increases as the boom 6 becomes longer and the number of hooks 14 increases, the number of winding layers of the wire 12 can be increased by arranging the winch drum 15 having a larger width. Can be suppressed. Therefore, even if the amount of winding of the wire 12 increases, the swivel post 5 of the present embodiment can prevent the winding property of the wire 12 from being lowered and the wire 12 from being bitten.

以上、本発明に係る実施の形態を例示したが、これらの実施の形態は本発明の内容を限定するものではない。また、本発明の請求項の範囲を逸脱しない範囲であれば、各種の変更等は可能である。   As mentioned above, although embodiment which concerns on this invention was illustrated, these embodiment does not limit the content of this invention. Various modifications can be made without departing from the scope of the claims of the present invention.

例えば、本実施の形態の旋回ポスト５では、一対の側板部５２１，５２１の各々を一枚板により平板状に形成したが、複数の板を接合して平板状に形成しても良い。   For example, in the swivel post 5 of the present embodiment, each of the pair of side plate portions 521 and 521 is formed in a flat plate shape by a single plate, but may be formed in a flat plate shape by joining a plurality of plates.

また、本実施の形態の旋回ポスト５では、一対の側板部５２１，５２１の上部５２１１，５２１１に支持軸配置部５２１１ａ及びウインチドラム配置部５２１１ｂを形成したが、いずれか一方でも良い。   Further, in the swivel post 5 of the present embodiment, the support shaft arrangement part 5211a and the winch drum arrangement part 5211b are formed on the upper parts 5211 and 5211 of the pair of side plate parts 521 and 521, but either one may be used.
