Description

本発明は、測量機の中で、土木や建築の工事現場で高さの基準となるレーザレベル（レーザ投光器）を支持するための測量機用エレベータ三脚に関する。 The present invention relates to an elevator tripod for a surveying instrument for supporting a laser level (laser projector) serving as a height reference in a construction site of civil engineering or construction in a surveying instrument.

本件出願人が先に特願２００８−３２９７４５号で提案した掘削支援装置をバックホウに取り付けて作動させる際に、所望する掘削高さの１．４メートル〜１．９メートルの高さにレーザ光を投光しなければならない。そのために開発されたレーザレベルの三脚用昇降装置である。この昇降装置はレーザ光を溝掘り掘削においては、地盤の高さより低い位置から、２メートルを超えるくらいの高さまで、レーザ光を投光出来るものである。従来の測量機の三脚は、１メートルくらいから１．５メートルくらいまで調整可能なエレベータ式の三脚はあった。
実開平７−５２５０ 特開平１１−５１６５３ When the present applicant previously operates the excavation support apparatus proposed in Japanese Patent Application No. 2008-329745 by attaching it to the backhoe, the laser beam is applied to a desired excavation height of 1.4 m to 1.9 m. Must be flooded. This is a laser-level tripod lifting device developed for this purpose. This elevating device can project laser light from a position lower than the height of the ground to a height of more than 2 meters when digging laser light. Conventional tripod tripods were elevator-type tripods that can be adjusted from about 1 meter to about 1.5 meters.
Japanese Utility Model 7-5250 JP-A-11-51653

従来の測量機を低い高さに設定する方法は、三脚を大きく開いて、エレベータ式の軸を一番短くして設定する方法が、一番低い設定方法であった。高い位置に関しては、三脚の伸縮する足を一番長くして設定し、エレベータ式を利用して高い位置まで伸ばすことができた。結果、低い高さに設定することは、出来なかった。本考案は従来の測量機の設定に関するこのような問題に鑑見てなされたものであって、設定位置が溝掘り掘削においては、地盤よりも低い場合にも使用することができ、なおかつ高い位置まで途切れることなく、設定可能なレーザレベルの三脚用昇降装置を提供することを目的とする。 The method of setting a conventional surveying instrument to a low height is the lowest setting method by opening the tripod wide and setting the elevator shaft to the shortest. As for the high position, the tripod's extendable leg was set to be the longest, and it could be extended to a high position using the elevator system. As a result, it was not possible to set a low height. The present invention has been made in view of such a problem related to the setting of a conventional surveying instrument, and can be used even when the setting position is lower than the ground in trench excavation, and still has a high position. An object of the present invention is to provide a tripod lifting device having a laser level that can be set without interruption.

このような、目的を達成するために、測量用三脚の脚頭に、着脱可能なレーザレベルの昇降装置であって、前記昇降装置の昇降軸は２mほどの長さで上下両端と中ほどにレーザレベルを設置する台座を設け、回転手段によってギア機構を介して前記昇降軸が昇降操作される昇降装置と、前記レーザレベルを昇降装置に設置した場合の重心を安定させるためのカウンターウェイトとを、水準機構を下側に備えた基部の上に構成した。また前記昇降装置の昇降軸が中ほどに設けた台座付近で、分割可能に構成され、蝶ねじによって脱着できるように構成した。前記昇降装置の昇降軸のガイド側の面には昇降移動量が分かるようにセンチ及びミリ単位の表示がされていることを特徴とする構成にした。 In order to achieve such an object, it is a laser level lifting device that can be attached to and detached from a leg of a tripod for surveying, and the lifting shaft of the lifting device has a length of about 2 m and is located at the upper and lower ends and the middle. A pedestal for installing a laser level is provided, and a lifting device in which the lifting shaft is lifted and lowered by a rotating means via a gear mechanism, and a counterweight for stabilizing the center of gravity when the laser level is installed in the lifting device. A leveling mechanism was constructed on the base with the lower side. Moreover, it was comprised so that it could be divided | segmented by the raising / lowering axis | shaft of the said raising / lowering apparatus in the vicinity of the base provided in the middle, and it comprised so that it could remove | desorb by a thumbscrew. The surface on the guide side of the lifting shaft of the lifting device is displayed in centimeters and millimeters so that the amount of lifting movement can be seen.

このように本発明によれば、レーザレベルの三脚用昇降装置の台座が、昇降自在であるために、溝掘り掘削においては、地盤より低い位置から２メートルを超える位置まで、レーザレベルを設定可能となった。このことによって、特願２００８−３２９７４５に提案されている掘削支援装置を使用する場合、所望する掘削高さの１．４ｍ〜１．９ｍ上方の高さの範囲の中でのレーザレベルの設定が早く、簡単にできるようになった。 As described above, according to the present invention, since the pedestal of the lifting device for the tripod at the laser level is freely movable, the laser level can be set from a position lower than the ground to a position exceeding 2 meters in digging. It became. As a result, when the excavation support device proposed in Japanese Patent Application No. 2008-329745 is used, the laser level can be set within a range of 1.4 m to 1.9 m above the desired excavation height. It became quick and easy.

本発明のレーザレベルの三脚用昇降装置の実施例を図に基づいて説明する。図１は、本発明のレーザレベルの三脚用昇降装置の側面図である。図２は、本発明のレーザレベルの三脚用昇降装置の基部付近の断面図である。市販されているレベル用の三脚２の脚頭３の上に、本発明レーザレベルの三脚用昇降装置１を設置して使用できるようになっている。
前記昇降装置は、基部５の上部に昇降軸６がギア機構９によって上下するように取り付けられており、昇降軸６には、レーザレベル４が設置される台座７が３か所設けられている。また、三脚２の中心よりレーザレベル４の位置がずれているため、転倒を防止するために中心よりレーザレベル４の反対側にカウンターウェイト１２を設けている。 Embodiments of a laser-level tripod lifting apparatus according to the present invention will be described with reference to the drawings. FIG. 1 is a side view of a laser level tripod lifting apparatus according to the present invention. FIG. 2 is a cross-sectional view of the vicinity of the base of the lifting device for a tripod for a laser level according to the present invention. The laser level tripod lifting / lowering device 1 of the present invention can be installed on the leg head 3 of a commercially available level tripod 2 for use.
The elevating device is attached to the upper portion of the base 5 so that the elevating shaft 6 is moved up and down by a gear mechanism 9, and the elevating shaft 6 is provided with three pedestals 7 on which the laser level 4 is installed. . Further, since the position of the laser level 4 is deviated from the center of the tripod 2, a counterweight 12 is provided on the opposite side of the laser level 4 from the center in order to prevent toppling.

昇降軸６は、レーザレベルの三脚用昇降装置１を設置した状態で、地盤高さより低い高さから地盤より２メートルを超える高さまでどの高さにおいても、レーザレベルを設置できる長さを持つ。また、昇降軸６の上下の端部と中ほどにレーザレベルを設置できる台座７を備えている。各台座７には円形気泡管１５を設けている。本考案の例においては、昇降軸６は２mの長さで各台座６間は、１mの間隔を持つ。また持ち運びのために、下側１mの昇降軸脱着部Dは、脱着可能に形成されている。また、昇降軸６側面には、センチ及びミリ単位の目盛１６が表示されており、移動した昇降幅が分かるようになっている。また、昇降軸６の三脚２側面には、軸線方向にラックが刻設されており、このラックにはギア機構９に内蔵されたピニオンが噛み合っている。このピニオンはクランクハンドル１１に連結されたウォームに噛み合っており、クランクハンドル１１を回転操作することで昇降軸６が軸線方向に昇降し、台座７の高さ位置を調整可能にしている。 The elevating shaft 6 has a length capable of installing a laser level at any height from a height lower than the ground height to a height exceeding 2 meters above the ground with the laser level tripod lifting device 1 installed. Moreover, the base 7 which can install a laser level is provided in the up-and-down edge part of the raising / lowering axis | shaft 6 and the middle. Each pedestal 7 is provided with a circular bubble tube 15. In the example of the present invention, the lifting shaft 6 has a length of 2 m and a space of 1 m between the pedestals 6. Further, for carrying, the lower shaft 1 m of the lifting shaft attaching / detaching portion D is formed to be attachable / detachable. A scale 16 in centimeters and millimeters is displayed on the side surface of the lifting shaft 6 so that the moved lifting width can be seen. Further, a rack is engraved on the side surface of the tripod 2 of the lifting shaft 6 in the axial direction, and a pinion built in the gear mechanism 9 is engaged with this rack. The pinion meshes with a worm connected to the crank handle 11, and when the crank handle 11 is rotated, the elevating shaft 6 moves up and down in the axial direction so that the height position of the base 7 can be adjusted.

昇降軸６を軸線方向に移動可能に保持するコの字状の溝を形成したガイド１０が、ギア機構９両側から昇降軸６を挟むように設けられている。また、昇降後、昇降軸６のガタつきを無くすための固定ネジ１３をガイド１０上下左右に４か所に設けている。 A guide 10 having a U-shaped groove for holding the lifting shaft 6 movably in the axial direction is provided so as to sandwich the lifting shaft 6 from both sides of the gear mechanism 9. In addition, fixing screws 13 for eliminating rattling of the lifting shaft 6 after lifting and lowering are provided at four positions on the guide 10 in the vertical and horizontal directions.

カウンターウェイト１２は、レーザレベル４の大きさによって重量を増減できるようになっており、少しレーザレベルより重い方が安定している。 The weight of the counterweight 12 can be increased / decreased depending on the size of the laser level 4, and is more stable when it is slightly heavier than the laser level.

本発明のレーザレベルの三脚用昇降装置１の使用方法を説明する。前記昇降装置は、昇降軸６が長いので、初めは下側の昇降軸脱着部Dを外しておく。設置したい場所に、三脚２を立てて脚頭３の上に三脚用昇降装置１を取り付ける。それから、昇降軸６のガイド１０の固定ネジ１３を締めて昇降軸６を固定する。三脚２の脚頭３もほぼ水平に立てたいので、昇降装置１を三脚２に取り付けた状態で、台座７に取り付けられた円形気胞管１５を見ながら水平に立てる。微調整は、基部５の下側に設けられた水準機構８で調整する。特願２００８−３２９７４５に提案されている掘削支援装置を使用する場合、指定掘削高さH0の１．４ｍ〜１．９ｍ上方の高さの範囲の中に（掘削するバックホウの機種で数値は変わる）、レーザレベルの設定をしなければならない。
図３は、本発明のレーザレベルの三脚用昇降装置の上下水道工事における溝掘削の場合の実施例の平面図である。まず、指定掘削高さH0（所望する掘削高さ）の１．４m程度上方の位置を検討してみる。たとえば、指定掘削高さH0が地盤高さくらいであれば、１．４m上がった高さは、三脚２の脚頭３くらいなので、そのくらいの高さにレーザレベル４を設置する。それから、正確にレーザレベル４によって掘削深さを割り出す。もし、１．４mから低い場合は、低い高さだけレーザレベル４を昇降軸６の側面の目盛を見ながら上昇させる。最後に掘削高さをもう一度確認しておく。次に、下水道工事などで地盤からの掘削が深い場合、例えば、地盤から１．５m程度下方を掘削する場合、一部掘削した溝に三脚２を図３のように掘削溝２０をまたがせて足を広げて、円形気泡管１５を合わせて設置する。指定掘削深さH0の１．４mくらい上がったところがレーザレベル４の設置する位置であるから、下の端の台座７の位置を、地盤より０．１mほど下がった状態に昇降軸６を移動させる。最初にレーザレベル４を設置する位置は、中段の台座７が地盤より０．９mくらい上がっているので、中段の位置に設置して、それから指定掘削深さH0から昇降軸６中段位置でのレーザ光高さまでの距離L1の高さを出す。L１の値がたとえば２．６ｍだとすると、下の台座７に設置した場合のレーザレベルの高さは１．６mなので０．２mほど昇降軸を下げて、もう一度掘削高さを確認する。それから、レーザレベル４を下の台座７に移動して設置する。最初に台座７を水平にセットしてそれからレーザレベル側の水平もセットしているので移動した場合、ほとんど誤差は無視できるが、本考案のレーザレベルの三脚用昇降装置１は、掘削専用の高さ管理なので、誤差は無視してよい。 A method of using the laser level tripod lifting / lowering device 1 of the present invention will be described. Since the elevating shaft 6 is long in the elevating device, the lower elevating shaft attaching / detaching portion D is first removed. A tripod 2 is erected at a place where it is desired to be installed, and a tripod lifting device 1 is mounted on the leg head 3. Then, the elevating shaft 6 is fixed by tightening the fixing screw 13 of the guide 10 of the elevating shaft 6. Since the leg head 3 of the tripod 2 is also desired to be set almost horizontally, the elevating device 1 is mounted on the tripod 2 while standing while looking at the circular air duct 15 attached to the pedestal 7. The fine adjustment is performed by a level mechanism 8 provided on the lower side of the base 5. When using the excavation support device proposed in Japanese Patent Application No. 2008-329745, it is within the range of 1.4m to 1.9m above the specified excavation height H0. ) The laser level must be set.
FIG. 3 is a plan view of an embodiment in the case of trench excavation in the water and sewage work of the laser level tripod lifting device of the present invention. First, consider a position about 1.4m above the designated excavation height H0 (desired excavation height). For example, if the designated excavation height H0 is about the ground height, the height increased by 1.4 m is about the head 3 of the tripod 2, so the laser level 4 is installed at that height. Then, the excavation depth is accurately determined by the laser level 4. If it is lower than 1.4 m, the laser level 4 is raised by a low height while looking at the scale on the side of the lifting shaft 6. Finally, check the excavation height again. Next, when excavation from the ground is deep due to sewerage work, for example, when excavating about 1.5 m below the ground, the tripod 2 is placed over the excavated groove 20 as shown in FIG. Spread the legs and install the circular bubble tube 15 together. Since the place where the specified excavation depth H0 is increased by 1.4 m is the position where the laser level 4 is installed, the lifting shaft 6 is moved so that the position of the base 7 at the lower end is lowered by about 0.1 m from the ground. . The position where the laser level 4 is initially set is that the middle pedestal 7 is about 0.9 m higher than the ground. Therefore, the laser level 4 is installed at the middle position, and then the laser at the middle position of the lifting shaft 6 from the designated excavation depth H0. The height of the distance L1 to the light height is obtained. If the value of L1 is 2.6 m, for example, the height of the laser level when installed on the lower pedestal 7 is 1.6 m, so the lifting shaft is lowered by about 0.2 m and the excavation height is confirmed again. Then, the laser level 4 is moved to the lower pedestal 7 and installed. When the pedestal 7 is first set horizontally and then the laser level side is also set, the error is negligible. However, the laser level tripod lifting / lowering device 1 of the present invention has a high height dedicated to excavation. Since it is management, the error can be ignored.

台座間移動における誤差をここで考えてみる。ひとつの台座７の円形気泡管１５に水平を合わせて本発明のレーザレベルの三脚用昇降装置１を立てるのであるが、昇降軸６が変形、若しくは傾いて昇降する場合、例えば角度で５度傾斜すると昇降軸６の長さが２mあるので、垂直方向の距離が２ｍ×COS５＝１．９９２ｍとなり１センチ程度短くなる。上下両端部の台座７間の移動は、１センチほど誤差が出るようになる。しかし上述と同じように、掘削専用の高さ管理なので、かまわない。 Now consider the error in movement between pedestals. The laser level tripod lifting / lowering device 1 according to the present invention is set up in horizontal alignment with the circular bubble tube 15 of one pedestal 7, but when the lifting / lowering shaft 6 is deformed or tilted, it is tilted at an angle of 5 °, for example. Then, since the length of the lifting shaft 6 is 2 m, the vertical distance is 2 m × COS5 = 1.922 m, which is shortened by about 1 cm. The movement between the pedestals 7 at both the upper and lower end portions will cause an error of about 1 cm. However, as described above, the height management is exclusively for excavation, so it does not matter.

本発明のレーザレベルの三脚用昇降装置１は、市販の三脚２に脱着して使用するようになっているが、専用型として、三脚２の中心に昇降装置を設置して、それを囲うようにコの字状に基部５を形成し、その基部５を三脚２で支持する構成にしてもかまわない。 The laser-level tripod lifting device 1 of the present invention is used by being attached to and detached from a commercially available tripod 2, but as a dedicated type, a lifting device is installed at the center of the tripod 2 so as to surround it. Alternatively, the base 5 may be formed in a U-shape and the base 5 may be supported by the tripod 2.
