Description

本考案は、本体中央部にマンホール蓋引っ掛け棒、両側に車輪を設けたマンホール蓋の開閉に関するものである。   The present invention relates to opening and closing of a manhole cover provided with a manhole cover hooking rod at the center of the main body and wheels on both sides.

マンホール蓋開閉作業を行う場合、作業員２名で従来の治具をマンホール鍵穴に直接挿入し、蓋本体を持ち上げなければならなかった。     When opening and closing the manhole cover, two workers had to insert the conventional jig directly into the manhole keyhole and lift the lid body.

常時作業員２名による作業は経済的負担も大きく、また、蓋開閉用治具を手に持って運ばなければならないため、移動時の労働的負担でもある。従って、テコの機能と車輪の機能を一体化することにより、マンホール蓋開閉作業を作業員１名で容易な労力で行うことが可能になり前述の欠点を解決しようとするものである。     The work by two regular workers is a heavy economic burden, and it is a labor burden when moving because the lid opening / closing jig must be carried in the hand. Therefore, by integrating the lever function and the wheel function, the manhole cover opening / closing operation can be performed by one worker with an easy effort, and the above-described drawbacks are to be solved.

本考案は、マンホール蓋開閉装置本体に、テコの力を使って蓋を持ち上げるための引っ掛け棒を、本体中央部に設けた長穴に装着しマンホール蓋の鍵穴に挿入し作用棒を押し上げる。且つ、車輪の機能により持ち上げられた蓋の前後へのスライドを可能にしている。また、長穴は本体設置位置の多少のずれに自在に対応できることを可能にしている。     In the present invention, a hook for lifting the lid using the lever force is attached to the manhole cover opening / closing device main body, and is inserted into a long hole provided in the central portion of the main body, inserted into the keyhole of the manhole cover, and pushed up the action rod. In addition, the lid lifted by the function of the wheel can slide back and forth. In addition, the long hole makes it possible to cope with a slight shift of the main body installation position.

上述の様に、本考案のマンホール蓋開閉装置は、テコの力を利用して蓋を持ち上げる機能は勿論、本体全体を軽量パイプで構成しているため、軽量かつ丈夫で両側に設置されている車輪の機能により、マンホール蓋を持ち上げた状態での移動が容易にでき、一連の作業を一人で行うことが可能であり、労力の低減として役立つ。     As described above, the manhole cover opening and closing device of the present invention has a function of lifting the cover using the leverage of the lever, as well as the entire body made of a lightweight pipe, so it is light and strong and is installed on both sides. The wheel function facilitates movement with the manhole cover lifted, and a series of operations can be performed by one person, which is useful for reducing labor.

マンホール蓋開閉装置本体両側の車輪の間にマンホール蓋が納まるように本体を設置し、作用棒を押し下げた時に引っ掛け棒がマンホール蓋鍵穴から抜けないように、引っ掛け棒を挿入したのち９０°回転させ、引っ掛け棒先端部分が裏蓋面にしっかりと引っ掛かった状態で支承する。また、マンホール蓋を持ち上げたまま本体を押すか引っ張ることにより、車輪の機能が働き、マンホール蓋のスライドが可能となる。また、装置本体の作用棒の根元部分の着脱ピンを抜くことにより、作用棒を取り外すことができ、コンパクトな収納が自在となる。     Manhole cover opening / closing device Install the main body so that the manhole cover fits between the wheels on both sides of the main body, and rotate it 90 ° after inserting the hook rod so that the hook rod does not come out of the manhole cover keyhole when the action rod is pushed down. The bearing is supported in a state where the tip of the hooking rod is firmly hooked on the back cover surface. Further, by pushing or pulling the main body with the manhole cover lifted, the wheel functions and the manhole cover can be slid. Further, by pulling out the attaching / detaching pin at the base part of the working bar of the apparatus main body, the working bar can be removed, and compact storage becomes possible.

以下、添付図面に従って一実例を説明する。１は軽量かつ耐久性のあるアルミ管を適宜素材にて形成された作用棒、４は作用棒を収納するために設けた着脱部位で、この着脱部位４はピン４ａを差し抜きすることで作用棒１の着脱が自在となる。３は１と同様素材で前後２本のパイプで形成している本体中央部で、本体中央部３の前方管３ａの両サイドに開けられた長穴５にマンホール蓋を開けるための、引っ掛け棒本体７を挿入する。     Hereinafter, an example is demonstrated according to an accompanying drawing. Reference numeral 1 is a working rod made of a light and durable aluminum tube made of an appropriate material, 4 is an attaching / detaching portion provided for housing the acting rod, and this attaching / detaching portion 4 works by inserting and removing the pin 4a. The rod 1 can be attached and detached freely. 3 is a central part of the main body formed by two pipes, which are the same material as 1, and a hook rod for opening a manhole cover in the long hole 5 opened on both sides of the front pipe 3 a of the central part 3 of the main body. Insert the body 7.

前述の引っ掛け棒本体７の頭部９のＴ字ハンドルは端部８がマンホール蓋裏面に引っ掛った状態にするために９０°回転させ、作用棒１を押し下げ腹部に設けた荷重受けワッシャ１０で本体中央部３の前方管３ａにマンホール蓋の荷重を伝えることで蓋が持ち上がり、１及び３と同様素材で形成された２は本体両側を構成し、この本体両側２の後方口縁部に枢着した車輪６により本体の移動が自在となる。また、頭部９を回転させ解錠すると、端部８が蓋からはずれ引っ掛け棒本体７がマンホール蓋からはずれる。     The T-shaped handle of the head portion 9 of the hook rod body 7 is rotated by 90 ° so that the end portion 8 is hooked on the back surface of the manhole cover, and the action rod 1 is pushed down by a load receiving washer 10 provided on the abdomen. By transmitting the load of the manhole cover to the front tube 3a of the central part 3 of the main body, the cover is lifted, and 2 formed of the same material as 1 and 3 constitutes both sides of the main body, and pivots on the rear edge of the two sides 2 of the main body. The body 6 can be freely moved by the worn wheels 6. When the head 9 is rotated and unlocked, the end 8 is detached from the lid, and the hook body 7 is detached from the manhole lid.
