Description

本発明は、走行レール上を駆動する走行装置を備えたチェーンブロックに関するもので、さらに詳しくは、トロリフレームのフレームの幅を調整可能としたチェーンブロックに関するものである。   The present invention relates to a chain block including a traveling device that drives on a traveling rail, and more particularly to a chain block that can adjust the width of a trolley frame.

本出願人の出願に係る先行技術として、走行レール上を駆動する走行駆動装置を備えたチェーンブロックにおいて、走行レールの左右両側に配設され、走行車輪を軸着した左右トロリフレームと、前記走行車輪の下方で、トロリフレーム間にカラーを介して軸装され、ロードシーブを同軸上に軸承した駆動軸を有し、前記駆動軸で前記左右トロリフレームを前後揺動可能に連結し、カラーを変更することでトロリフレーム幅を変更することができるようにしたチェーンブロックが提案されている。(特許文献１)
特願2006-92830号 As a prior art related to the applicant's application, in a chain block provided with a travel drive device that drives on a travel rail, left and right trolley frames that are disposed on both the left and right sides of the travel rail and pivotally mounted on travel wheels, and the travel Below the wheel, a shaft is mounted between the trolley frames via a collar, and has a drive shaft on which a load sheave is coaxially supported. A chain block has been proposed in which the trolley frame width can be changed by changing. (Patent Document 1)
Japanese Patent Application No. 2006-92830

この先行技術では、左右トロリフレーム間にロードシーブを軸承した駆動軸を軸装し、左右トロリフレームを前記駆動軸で揺動可能に連結し、両トロリフレームを駆動軸を中心に揺動可能に連結する構成としたので、各走行車輪には荷重が均等に掛かるため、走行レールの凹凸により走行車輪が上下に変動しても、トロリフレームは変動に追従して前後に揺動し、変動を吸収するので走行車輪を円滑に駆動することができるとともに、駆動軸をカラーを介してトロリフレームに軸装することで、走行レールの幅が変更しても、駆動軸に嵌合するカラーの長さを変更してトロリフレーム幅を変更することが可能となるという作用を有するが、トロリフレームの幅を変更するためにカラーを用いるため、トロリフレーム幅の微調整が困難であるとともに、ワッシャとの組み合せ方法の選択も難しく、走行レール幅の変更により、トロリフレーム幅を微調整することが難しいという課題を有していた。さらに、トロリを走行レールに上架する際には重量の大きいトロリフレームを手動で移動させなければならず、特にトロリフレームの片側に巻上機用減速機、もう片側に横行用減速機を配置する形態のトロリにおいてはとくに重量が重いのでフレーム間の調整が困難であるという課題を有していた。   In this prior art, a drive shaft bearing a load sheave is mounted between the left and right trolley frames, the left and right trolley frames are connected so as to be swingable by the drive shaft, and both trolley frames can be swung around the drive shaft. Since the load is applied evenly to each traveling wheel because it is connected, even if the traveling wheel fluctuates up and down due to the unevenness of the traveling rail, the trolley frame swings back and forth following the variation, causing fluctuations. Because it absorbs, the traveling wheel can be driven smoothly, and the length of the collar that fits to the drive shaft can be adjusted by mounting the drive shaft on the trolley frame via the collar even if the width of the travel rail changes. It is possible to change the trolley frame width by changing the height, but because the color is used to change the width of the trolley frame, it is difficult to finely adjust the trolley frame width. Moni, harder choice of method combination of a washer, the change of the running rail width, there is a problem that it is difficult to finely adjust the trolley frame width. Furthermore, when the trolley is mounted on the traveling rail, the heavy trolley frame must be manually moved, and in particular, a hoisting speed reducer is arranged on one side of the trolley frame and a traverse speed reducer is arranged on the other side. The trolley in the form has a problem that adjustment between the frames is difficult because the weight is particularly heavy.

本発明は前記した課題を解決するもので、左右一対のトロリフレームと、ロードシーブを駆動する駆動軸と、走行レールを走行する走行装置を備えたチェーンブロックにおいて、前記トロリフレームに駆動軸とフレーム幅調整軸を軸着し、前記駆動軸は、軸受けを介してトロリフレームに軸方向スライド可能に、前記フレーム幅調整軸は、調整軸の一側が、一方のトロリフレームにねじ機構を介してトロリフレームを進退可能に、他側が、他方のトロリフレームに回転可能で軸方向スライド不能に軸着したことを特徴とする。   The present invention solves the above-described problem. In a chain block including a pair of left and right trolley frames, a drive shaft that drives a load sheave, and a travel device that travels on a travel rail, the drive shaft and the frame are connected to the trolley frame. A width adjusting shaft is attached, the drive shaft is slidable in the axial direction on the trolley frame via a bearing, and the frame width adjusting shaft has one side of the adjusting shaft connected to one trolley frame via a screw mechanism. The other side is rotatably attached to the other trolley frame so as to be able to advance and retreat the frame, and is axially attached so as not to slide in the axial direction.

また、前記調整軸の一側に雄ねじを形成し、前記雄ねじを一方のトロリフレームに嵌合する雌ねじに螺合したことを特徴とする。     Further, a male screw is formed on one side of the adjustment shaft, and the male screw is screwed into a female screw fitted to one trolley frame.

また、前記駆動軸にロードシーブとロードチェーンの係合をガイドするクサリガイドを軸受けを介して回転可能に軸着したことを特徴とする。     Further, a chain guide for guiding the engagement between the load sheave and the load chain is rotatably mounted on the drive shaft through a bearing.

また、前記クサリガイドとトロリフレーム間にトロリフレーム間の間隔規制用スリーブを設けたことを特徴とする。     In addition, a sleeve for regulating an interval between the trolley frames is provided between the chain guide and the trolley frame.

本発明によれば、チェーンブロックの駆動軸を、軸受けを介してトロリフレームに軸方向スライド可能に軸着し、左右一対のトロリフレームに、フレーム幅調整軸を軸着し、前記調整軸の一側を、一方のトロリフレームにねじ機構を介してトロリフレームを進退可能に螺合し、他側を、他方のトロリフレームに回転可能に、かつ軸方向スライド不能に軸着したので、調整軸を回転することで、ねじ機構を介して一方のトロリフレームが進退し、駆動軸もトロリフレームの進退により軸方向にスライドするので、トロリフレーム間の間隔を容易かつ正確に調整することができる。さらに、重量の重いトロリを走行レール上に上架する際においても、調整軸を回転することでトロリフレーム幅を調整できるので、作業者の負担を軽減することができる。   According to the present invention, the drive shaft of the chain block is axially slidably mounted on the trolley frame via the bearing, the frame width adjustment shaft is axially mounted on the pair of left and right trolley frames, and one of the adjustment shafts is mounted. The trolley frame is threadably engaged with one trolley frame via a screw mechanism so that the trolley frame can be advanced and retracted, and the other side is pivotally attached to the other trolley frame and non-slidable in the axial direction. By rotating, one trolley frame moves forward and backward through the screw mechanism, and the drive shaft also slides in the axial direction by the forward and backward movement of the trolley frame. Therefore, the interval between the trolley frames can be adjusted easily and accurately. Furthermore, even when a heavy trolley is mounted on the traveling rail, the width of the trolley frame can be adjusted by rotating the adjustment shaft, so that the burden on the operator can be reduced.

さらに、駆動軸にロードシーブとロードチェーンの係合をガイドするクサリガイドを軸受けを介して相対回転可能に設け、前記クサリガイドとトロリフレーム間にトロリフレーム間の間隔規制用スリーブを設けたので、予め走行レール幅に見合うスリーブを用意しておくことで、トロリフレーム間の間隔をさらに正確に調整することができる。   In addition, a chain guide for guiding the engagement of the load sheave and the load chain is provided on the drive shaft so as to be relatively rotatable via a bearing, and a sleeve for regulating the interval between the trolley frames is provided between the chain guide and the trolley frame. By preparing a sleeve corresponding to the width of the traveling rail in advance, the interval between the trolley frames can be adjusted more accurately.
