Description

本発明は、水槽用覆蓋装置に関するものであり、特に浄水場,汚水処理場その他の屋外の水処理場における大型水槽の可動式覆蓋装置に関するものである。   The present invention relates to a cover device for a water tank, and more particularly to a movable cover device for a large water tank in a water purification plant, a sewage treatment plant or other outdoor water treatment plants.
水処理を行う水槽の覆蓋は、随時に開閉する必要上水槽の両側部に沿って設置されたレール上を走行する可動式の覆蓋である。また、両側壁間のスパン(幅)が大きい(例えば10m以上)屋外の大型水槽では、積雪の荷重を考慮したり、太陽光発電のため上部に太陽電池モジュールを設置するなど空間の有効利用の促進と相俟って、強度上の要請からラーメン(山形ラーメン又は矩形ラーメン)構造の骨組を持つ蓋が使用される。   The cover of the water tank that performs water treatment is a movable cover that travels on rails installed along both sides of the necessary water tank that can be opened and closed as needed. Also, in large outdoor aquariums where the span between both side walls is large (for example, 10m or more), it is possible to effectively use the space by taking into account the snow load or installing a solar cell module at the top for solar power generation. In combination with the promotion, a lid having a framework of a ramen (Yamagata ramen or rectangular ramen) structure is used due to strength requirements.
図10を参照して従来のこの種の水槽の覆蓋装置の概略を説明する。
ラーメン構造でSUS製の骨組を持つ覆蓋4はそれぞれ複数の上段の覆蓋4aと下段の覆蓋4bとから構成され、レール5も各上下段の覆蓋4a,4bと対応するように水槽1の両側部に沿って設置された平行な各対のレール5a,5bから構成されている。
水槽1の両側壁10,10の内側上部には、水平な棚状受板11,11が取り付けられている。各棚状受板11は、ぞれぞれ所定の間隔にブラケット13を配置して垂直な取付板12とともに断面アングル状に組み合わされ、取付板12をアンカーボルトなどの取付具を用いて対応する側壁10へ固定することにより、各側壁10の内側上部へ上記の状態に固定されている。
With reference to FIG. 10, the outline of the conventional cover apparatus of this kind of water tank is demonstrated.
The cover 4 having a frame structure made of SUS and having a framework made of SUS is composed of a plurality of upper cover 4a and lower cover 4b, and the rail 5 also has both sides of the water tank 1 so as to correspond to the upper and lower cover 4a, 4b. The rails 5a and 5b are parallel to each other.
Horizontal shelf-like receiving plates 11 and 11 are attached to the inner upper portions of both side walls 10 and 10 of the water tank 1. Each shelf-like receiving plate 11 is arranged in a cross-sectional angle with a vertical mounting plate 12 by arranging brackets 13 at predetermined intervals, and the mounting plate 12 corresponds to the mounting plate 12 using an attachment such as an anchor bolt. By fixing to the side wall 10, it fixes to the inner upper part of each side wall 10 in the said state.
上段の覆蓋4aが走行する外側(水槽1の中心から見て外側)の各レール5aと、下段の覆蓋4bが走行する内側の各レール5bはSUS製でパイプ状のレールであり、水槽1の両側の棚状受板11の上面へ浮上した状態で設置されている。この形態では、各支柱50,51の下部に設置ベース14を溶接し、設置ベース14をねじ等で棚状受板11の上面へ固定することにより、各棚状受板11の上面へ所定間隔に支柱50,51を設置し、これらの各支柱50,51の上にそれぞれレール5a,5bを溶接している。
各覆蓋4a,4bの両側の脚部40,41の下部両端寄り部分には、両側壁部に先下がり傾斜した長さ方向に沿うフランジ部を有する逆樋状の保持枠42がそれぞれねじにより取り付けられている。この保持枠42の内部には垂直状態の走行車輪43が、各フランジ部には両側下部より傾斜した状態の各拘束車輪44が、それぞれ対応するレール5a,5bヘ転接するように取り付けられている(この走行部の構成は、後記特許文献1参照)。
複数の各覆蓋4a,4bで水槽1が覆われた状態では、上段の覆蓋4aは水槽1の長さ方向へ所定長さ下段の覆蓋4bとオーバーラップするようになっている。
The outer rails 5a on which the upper cover 4a travels (outside as viewed from the center of the water tank 1) and the inner rails 5b on which the lower cover 4b travels are pipe-like rails made of SUS. It is installed in a state where it floats on the upper surface of the shelf-like receiving plates 11 on both sides. In this embodiment, the installation base 14 is welded to the lower part of each of the columns 50 and 51, and the installation base 14 is fixed to the upper surface of the shelf-like receiving plate 11 with screws or the like. The columns 50 and 51 are installed on the rails, and the rails 5a and 5b are welded to the columns 50 and 51, respectively.
At the portions near the lower ends of the leg portions 40, 41 on both sides of the cover lids 4a, 4b, inverted saddle-shaped holding frames 42 having flange portions along the length direction inclined downward on both side wall portions are respectively attached by screws. It has been. Inside the holding frame 42, a traveling wheel 43 in a vertical state is attached, and in each flange portion, each restraining wheel 44 that is inclined from the lower part on both sides is attached to the corresponding rails 5a, 5b. (See Patent Document 1 below for the configuration of the traveling portion).
In a state where the water tank 1 is covered with the plurality of cover covers 4 a and 4 b, the upper cover cover 4 a overlaps the cover cover 4 b of the lower stage with a predetermined length in the length direction of the water tank 1.
上記水槽の覆蓋装置において、水槽1の上を開放するときは開放しようとする領域から覆蓋4a,4bを人力で押して走行させ移動させる。
各覆蓋4a,4bの平面形状は、水槽1の幅方向を長辺とする長方形であり、例えばそれらの幅(水槽1の幅方向の量)は10mを超え、長さは2.8m前後である。このように寸法が大きくラーメン構造の骨組を有する覆蓋4a,4bでは、それ自体の重量によりレール5a,5bに対して垂直荷重が作用し、同時に各レール5a,5bを側方に押す水平荷重が作用する。この場合水平荷重は垂直荷重の約3倍程度である。
そして、前記の水平荷重は拘束車輪44をレール5a,5bへ強く押し付けるように作用してそれらの円滑な回転を妨げるため、各覆蓋の走行性を悪くし、一人の作業員では各覆蓋を操作できないことがあった。
覆蓋4a,4bの上には空間の有効活用のため太陽光発電用の太陽電池モジュールが設置されることがあるほか、寒冷地では冬季に積雪があるので、これらにより前記水平荷重はさらに大きくなる。また、覆蓋の梁にアルミニウム又はアルミニウム合金(以下「アルミ合金等」と言う。)の成形材を用いた場合には、これらの金属はSUS等に比べて温度変化による収縮量が大きく、この場合は季節により前記水平荷重は大きくなるので、覆蓋の梁にはアルミ合金等でなくSUSが用いられていた。
特開2001−20647号公報
In the above water tank cover device, when the top of the water tank 1 is opened, the cover lids 4a and 4b are pushed and moved from the region to be opened by human power.
The planar shape of each cover 4a, 4b is a rectangle whose long side is the width direction of the water tank 1, for example, their width (amount in the width direction of the water tank 1) exceeds 10m, and the length is around 2.8m. is there. In the cover lids 4a and 4b having such a large frame structure having a rigid frame structure, a vertical load acts on the rails 5a and 5b due to its own weight, and at the same time, a horizontal load that pushes the rails 5a and 5b to the side is generated. Works. In this case, the horizontal load is about three times the vertical load.
The horizontal load acts to strongly press the restraining wheels 44 against the rails 5a and 5b to prevent their smooth rotation, so that the traveling performance of each cover is deteriorated, and one worker operates each cover. There was something I couldn't do.
A solar cell module for photovoltaic power generation may be installed on the cover lids 4a and 4b for effective use of space, and since there is snow in the winter in cold regions, the horizontal load is further increased by these. . In addition, when a molding material of aluminum or aluminum alloy (hereinafter referred to as “aluminum alloy etc.”) is used for the beam of the cover, these metals have a larger amount of shrinkage due to temperature change than SUS, etc. Since the horizontal load increases depending on the season, SUS is used instead of an aluminum alloy or the like for the beam of the cover.

本発明が解決しようとする課題は、水槽における可動式覆蓋の走行性の改善にあり、覆蓋をより軽く走行させることができ、温度変化によっても、また覆蓋の梁の材質によっても覆蓋の走行性を良好に保ち、一人の作業員でも覆蓋を操作することができる水槽用覆蓋装置を提供することにある。   The problem to be solved by the present invention is to improve the traveling performance of the movable cover in the water tank, so that the cover can be made to travel lighter, and the traveling performance of the cover is also affected by temperature changes and the material of the beams of the cover. An object of the present invention is to provide a water tank cover device that can maintain a good condition and can be operated by a single worker.
本発明に係る水槽用覆蓋装置は、前記課題を解決するため、水槽の両側部に沿って設置したレール上へ、ラーメン構造の骨組を持つ前記水槽の覆蓋を走行可能に複数設置し、前記各覆蓋の一側部の下部には、対応するレールへほぼ垂直状態で転接する少なくとも一つの走行車輪と当該レールへ両側より水平状態で又は両側下部より傾斜した状態で転接する拘束車輪とを一組として所定の間隔を置いて少なくとも二組設け、前記各覆蓋の他側部の下部には、対応するレールへほぼ垂直状態で転接する少なくとも一つの走行車輪を一組として所定の間隔を置いて少なくとも二組設けたことを最も主要な特徴としている。   In order to solve the above problems, the water tank cover device according to the present invention is provided with a plurality of water tank cover covers having a frame structure of ramen on the rails installed along both sides of the water tank. At the lower part of one side of the cover, a set of at least one traveling wheel that makes rolling contact with the corresponding rail in a substantially vertical state and a restraining wheel that makes rolling contact with the rail in a horizontal state from both sides or inclined from the lower part on both sides At least two sets are provided at a predetermined interval, and at the lower part of the other side portion of each cover, at least one traveling wheel that makes rolling contact with the corresponding rail in a substantially vertical state is set as a set and at least a predetermined interval is provided. The most important feature is the establishment of two sets.
本発明に係る水槽用覆蓋装置によれば、水槽の一方の側部のレールは拘束車輪によって拘束されているが、他方の側部のレールは垂直状態の走行車輪のみが転接していて拘束車輪による拘束を受けない解放構造であるので、水平荷重の影響が排除され、走行性の低下を防止することができる。
したがって、覆蓋の走行性が良好に保たれ、一人の作業員で覆蓋を操作することができる。また、覆蓋の上部に太陽光発電のために太陽電池モジュールを設置した場合でも、積雪がある場合でも、あるいは覆蓋の梁の材質(温度変化による膨縮量の大きさの相違)によっても、それらによる覆蓋の走行性への影響は小さい。
According to the water tank cover device according to the present invention, the rail on one side of the water tank is restrained by the restraining wheel, but only the traveling wheel in the vertical state is in rolling contact with the rail on the other side. Therefore, the influence of the horizontal load is eliminated, and the traveling performance can be prevented from being lowered.
Therefore, the running performance of the cover is kept good, and the cover can be operated by one worker. Also, even when a solar cell module is installed on the top of the cover for solar power generation, when there is snow, or depending on the material of the cover beam (the difference in the amount of expansion / contraction due to temperature changes) The influence on the running performance of the cover is small.

At least two sets are installed at positions separated along the traveling direction.
In this embodiment, as shown in FIG. 3, holding frames 22 made of an aluminum alloy or the like having a flange portion on both sides are provided at two locations in the longitudinal direction of the lower portions of the leg portions 20 and 21. The pair of traveling wheels 23 are attached to the inside of the holding frame 22 while being held by a cage (not indicated), while the restraining wheels 24 are attached to the flange portions of the holding frame 22. .
The holding frames 22 and 22 and the leg portions 20 and 21 of the upper and lower cover lids 2a and 2b corresponding to each of the holding frames 22 and 22 are shifted in both end positions of the corresponding cover lids 2a and 2b. When it does not synchronize with the other side, it is configured to rotate in the horizontal direction at each screw 20a, 21a to follow the deviation.
上下段の覆蓋2a,2bの左側の脚部20,21の下部の少なくとも二箇所には、対応するレール3a,3bへほぼ垂直状態で転接する前後対の走行車輪23のみが設けられている。各対の走行車輪23は図4で示すように、当該脚部20,21の下部ヘねじ20a(21a)により取り付けられたアルミ合金等製の逆樋状の各保持枠22a内へ、保持器にそれぞれ保持された状態で取り付けられている。
各保持枠22a,22aとそれに対応する上下の覆蓋2a,2bの脚部20,21とが対応するねじ20a,21aの部分で水平方向へ回転し、覆蓋2a,2bの両端位置のずれを吸収する構成であることは覆蓋2a,2bの右側部分と同じである。
At least two locations below the left leg portions 20 and 21 of the upper and lower cover lids 2a and 2b are provided with only a pair of front and rear traveling wheels 23 that make rolling contact with the corresponding rails 3a and 3b in a substantially vertical state. As shown in FIG. 4, each pair of traveling wheels 23 is provided with cages in each of the inverted saddle-shaped holding frames 22 a made of aluminum alloy or the like attached by the lower female screws 20 a (21 a) of the legs 20 and 21. Are attached to each of them.
The holding frames 22a and 22a and the leg portions 20 and 21 of the upper and lower cover lids 2a and 2b corresponding to the holding frames 22a and 22b rotate in the horizontal direction at the portions of the corresponding screws 20a and 21a, and absorb the deviation of the both end positions of the cover lids 2a and 2b. This is the same as the right side portion of the cover lids 2a and 2b.
下段の各覆蓋2bの脚部21,21相互は、図2で示すように中間部にターンバックル25aを有する一対(好ましくは長さ方向の両端部)の弦状の緊結バー25で連結されている。したがって、覆蓋2bの梁に比較的寸法が小さくより軽量なアルミ合金等の型材が使用された場合でもより高い剛性が得られ、水平荷重が大きくても両側の脚部21,21相互の先端間隔が広がる(山形の覆蓋2bが水平になるように変形する)のを防止することができる。
また、上段の各覆蓋2aの梁には強度の大きいアルミ合金等の型材を使用することにより、十分な剛性が得られるようにしてある。
As shown in FIG. 2, the leg portions 21 and 21 of the lower cover 2b are connected to each other by a pair (preferably both end portions in the length direction) of a string-like binding bar 25 having a turn buckle 25a in the middle portion. Yes. Therefore, even when a relatively small and lighter aluminum alloy or the like is used for the beam of the cover 2b, higher rigidity can be obtained, and even if the horizontal load is large, the distance between the tips of the legs 21 and 21 on both sides is great. Can be prevented (the mountain-shaped cover 2b is deformed to become horizontal).
Moreover, sufficient rigidity can be obtained by using a mold material such as an aluminum alloy having a high strength for the beam of each upper cover 2a.
図5で示すように、各覆蓋2a,2bの走行車輪23のみが設置されている左側の各脚部20,21の下部には、当該走行車輪23の風圧による浮上がりを防止するため、車輪の保持枠22aの設置位置以外の部分へ、対応するレール3a,3bの脚条部33以外の部分(レールの主部)の周囲を覆う引っ掛り部61を有する浮上がり防止具6が設置されている。各浮上がり防止具6は、対応する覆蓋2a,2bの端部が所定量浮上したとき前記引っ掛り部61が対応するレール3a,3bの主部ヘ引っ掛ることにより、覆蓋2a,2bの浮上脱線を防止する。
この実施形態における浮上がり防止具6は、垂直部の下端に円弧状断面の引っ掛り部61を有し、垂直部の上端に溝状部62を有するアルミ合金等の型材からなる相対する半割体60,60により構成されている。すなわち、同じ長さに切断した半割体60,60を、各カバー部61と各溝状部62とが相対するように両者の垂直部をボルトナット63により接合して浮上がり防止具6を組み立て、各半割体60の溝状部62,62が形成するあり溝状部にボルト頭部を案内したボルトナット64により各脚部20,21に取り付けている。

また、水槽1の全面を覆蓋2a,2bにより覆った状態では、当該水槽1の両端部に位置する覆蓋2と水槽1の周縁部とが形成する空間は適当な手段により塞がれるように構成されている。
なお、16は上面に縞状その他の凹凸を有するアルミ合金等の滑り止板である。
As shown in FIGS. 3 and 4, operating handles 26 and 27 are respectively attached to the upper surfaces of both end portions of the upper and lower cover covers 2 a and 2 b, and each handle 27 of the lower cover cover 2 b is In order to avoid interference with the upper cover 2a during traveling, it can be tilted.
A cover plate 28 made of aluminum alloy or the like is attached to the outer surface of each leg portion 20, 21 of each cover lid 2 a, 2 b, and each cover lid 2 a, together with the cover plate 28, is attached to the lower edge portion of each cover plate 28. A skirt 29 made of a flexible sheet made of rubber or synthetic resin is attached so as to close the space between the side portion 2b and the water stop plate 15.
Further, in a state where the entire surface of the water tank 1 is covered with the cover lids 2a and 2b, the space formed by the cover lid 2 located at both ends of the water tank 1 and the peripheral edge portion of the water tank 1 is configured to be closed by an appropriate means. Has been.
Reference numeral 16 denotes a non-slip plate made of an aluminum alloy or the like having stripes or other irregularities on the upper surface.
前記実施形態の水槽用覆蓋装置によれば、レール3a,3bの主部の断面外形は円形であり、各車輪23,24はそれらのレール3a,3bヘ点接触している。したがって、荷重により覆蓋2c,2bに撓み(水槽1の幅方向への撓み)が発生して覆蓋2a,2bの端部が傾いても、それらの撓みに応じて各車輪23,24が撓み方向へ傾くことによりそれに追随する。   According to the water tank cover device of the embodiment, the cross-sectional outer shape of the main part of the rails 3a and 3b is circular, and the wheels 23 and 24 are in point contact with the rails 3a and 3b. Therefore, even if the cover lids 2c and 2b are bent by the load (bending in the width direction of the water tank 1) and the ends of the cover lids 2a and 2b are inclined, the respective wheels 23 and 24 are bent in accordance with the bending. Follow it by leaning on.
各覆蓋2a,2bを走行させる一方の側部のレール3a,3bは拘束車輪24,24によって(走行車輪23が側方へ動かないように)拘束されているが、他方の側部のレール3a,3bは拘束されていず、覆蓋2a,2bの両脚部20,21の各先端相互の間隔が変化する方向への水平荷重の影響が排除され、走行性の低下を防止することができる。
したがって、覆蓋2の上に例えば太陽光発電のために太陽電池モジュールを搭載した場合でも、あるいは寒冷地等で積雪があった場合でも、覆蓋の走行性が良好に保たれ、一人の作業員により覆蓋を走行操作することができる。
The rails 3a, 3b on one side for running each cover 2a, 2b are restrained by restraining wheels 24, 24 (so that the running wheel 23 does not move sideways), but the rail 3a on the other side. , 3b are not restrained, the influence of the horizontal load in the direction in which the distance between the tips of the leg portions 20, 21 of the cover lids 2a, 2b changes is eliminated, and it is possible to prevent a decrease in running performance.
Therefore, even when a solar cell module is mounted on the cover 2 for solar power generation or when there is snow in a cold region or the like, the traveling performance of the cover is kept good, and one worker The cover can be operated to travel.
覆蓋2の梁にSUSよりも温度変化による伸縮量が大きいアルミ合金等の型材を使用すると、季節により平荷重が大きく変化し(高温期には覆蓋2の各脚部20,21の各相互間の間隔を拡大する方向の荷重が大きくなり、低温期には縮小する方向の荷重が大きくなる)、図10の従来の覆蓋装置ではその影響を受けて覆蓋2の走行性が変化するが、前記実施形態の覆蓋装置ではその影響を受けない。
したがって、本発明によれば前記実施形態のように覆蓋2の梁により軽量なアルミ合金等の型材を用いることができる。
When a material such as an aluminum alloy having a larger amount of expansion and contraction due to temperature change than SUS is used for the beam of the cover 2, the flat load changes greatly depending on the season (the temperature between the legs 20 and 21 of the cover 2 is high during the high temperature period). In the conventional cover device of FIG. 10, the traveling performance of the cover 2 changes under the influence of the conventional cover device of FIG. 10. The cover device of the embodiment is not affected by this.
Therefore, according to the present invention, a light mold material such as an aluminum alloy can be used for the beam of the cover 2 as in the above embodiment.
各レール3には長さ方向に沿って逆T字状(施工状態での逆T字状)の脚条部33を一体に形成し、レール3は支柱30,31に支持されたベース板32へねじ35により締め付けた各押え板34により前記脚条部33の各下部フランジを押え付けた状態で取り付けてあるので、気温上昇によるレール3の伸びを逃がすことができ、レール3の真直性が保たれる。
下段の覆蓋2bの両脚部21,21は、緊結バー25で連結されているので当該覆蓋2bの梁にアルミ合金等の型材を用いた場合でも高い剛性が保たれ、水平荷重によって両脚部21,21間の間隔が広がるのが防止される。
Each rail 3 is integrally formed with a leg 33 having an inverted T-shape (inverted T-shape in the construction state) along the length direction. The rail 3 is a base plate 32 supported by the support columns 30 and 31. Since the lower flanges of the leg portions 33 are pressed by the presser plates 34 tightened by the screw 35, the extension of the rail 3 due to the temperature rise can be released, and the straightness of the rail 3 is improved. Kept.
Since both the leg portions 21 and 21 of the lower cover 2b are connected by the fastening bar 25, high rigidity is maintained even when a mold material such as an aluminum alloy is used for the beam of the cover 2b. It is possible to prevent the interval between 21 from widening.
第2実施形態
図6は本発明に係る水槽用覆蓋装置の第2実施形態において拘束側レール部分を示す部分断面図、図7は第2実施形態のレール非拘束側を示す部分断面図(但し、上段の覆蓋に対応する部分は省略)、図8は図6の覆蓋装置における覆蓋の撓み追随手段を側面から見た部分側面図である。
第1実施形態の覆蓋装置では、レール3a,3bの主部は断面外形が円形であり、主として覆蓋2a,2bの荷重を受ける走行車輪23,24はレール3a,3bと点接触しているので、覆蓋2a,2bが受ける荷重(覆蓋自体の荷重のみならず、積雪や覆蓋の材料の伸び、太陽電池モジュール等による荷重を含む)の大きさによっては、走行車輪23とレール3a,3bとの接点に車輪23の強度不足が発生する場合がある。
Second Embodiment FIG. 6 is a partial cross-sectional view showing a restraining-side rail portion in a second embodiment of the aquarium cover device according to the present invention, and FIG. 7 is a partial cross-sectional view showing a rail non-restraining side of the second embodiment (however, FIG. 8 is a partial side view of the cover follower follow-up means in the cover device of FIG. 6 as viewed from the side.
In the cover device of the first embodiment, the main portions of the rails 3a and 3b have a circular cross-sectional outer shape, and the traveling wheels 23 and 24 that mainly receive the load of the cover lids 2a and 2b are in point contact with the rails 3a and 3b. Depending on the size of the load received by the cover 2a, 2b (including not only the load of the cover itself, but also snow, the material of the cover, the load of the solar cell module, etc.), the traveling wheel 23 and the rails 3a, 3b Insufficient strength of the wheel 23 may occur at the contact point.
この実施形態では、図6及び図7で示すように、前記強度不足を構造上解消するため走行車輪23と各レール3a,3bとの接触部を平面として両者を線接触状態としたものである。
その一例として、アルミ合金等の型材である車輪3a,3bは、その主部を断面外形が四角形の角パイプ状に形成し、当該主部内に垂直な補強リブ(符号なし)を形成するとともに、主部の下部に長さ方向に沿って断面逆T字状の脚条部33を形成している。
In this embodiment, as shown in FIGS. 6 and 7, in order to eliminate the above-described strength shortage, the contact portion between the traveling wheel 23 and each of the rails 3 a and 3 b is a plane and both are in a line contact state. .
As an example, the wheels 3a and 3b, which are mold materials such as aluminum alloy, have a main portion formed into a square pipe shape having a square cross-sectional outer shape, and a vertical reinforcing rib (no symbol) is formed in the main portion. A leg portion 33 having an inverted T-shaped cross section is formed in the lower portion of the main portion along the length direction.
水槽1の側壁10には止水板15を固定し、この止水板15の上縁は水槽1の開口縁から上方に立ち上がる止水壁15aを形成している。
水槽1の開口縁の側部のコンクリート打設面には、上面にレール3a,3bを支持するための支柱30,30が起立状に固定された設置ベース14が、水槽1の長さ方向に沿って所定の間隔で固定されており、各支柱30の上部には水平にベース板32が固定されている。
各ベース板32の上にレール3a,3bの脚条部33を重ねてねじ35で止めることにより、各支柱30,30へそれぞれレール3a,3bを支持させている。
A water stop plate 15 is fixed to the side wall 10 of the water tank 1, and an upper edge of the water stop plate 15 forms a water stop wall 15 a that rises upward from the opening edge of the water tank 1.
On the concrete placement surface at the side of the opening edge of the water tank 1, an installation base 14 in which support columns 30, 30 for supporting the rails 3 a, 3 b are fixed upright on the upper surface is provided in the length direction of the water tank 1. The base plate 32 is fixed horizontally to the upper part of each support column 30.
The rails 3a and 3b are supported on the support columns 30 and 30 by overlapping the leg portions 33 of the rails 3a and 3b on the base plates 32 and fastening them with screws 35, respectively.
レール拘束側(図6)及び非拘束側(図7)ともに、同形同サイズの保持枠22、22aが使用されており、逆U字状断面の保持枠22,22a内には保持器に保持された状態で対の走行車輪23(図8)が垂直に取り付けられ、これらの各走行車輪23はそれぞれ対応するレール3a,3bの上部の平面へ転接している。
拘束側においては、各保持枠22の下部両側のフランジ部下部へ拘束車輪24が水平に取り付けられ、これらの拘束車輪24は対応するレール3a,3bの垂直な側部へそれぞれ転接している。
図8で示すように、拘束側の拘束車輪24は対の走行車輪23相互の間の下部側方に位置しており、このように対の走行車輪23,23と一つの拘束車輪24とが一組となったものが、上下の覆蓋2a,2bの一方の側部の二箇所ヘ取り付けられている。
非拘束側では、対の走行車輪23,23を一組として、上下の覆蓋2a,2bの他方の側部の二箇所へ取り付けられている。
The holding frames 22 and 22a having the same shape and the same size are used on both the rail constraining side (FIG. 6) and the non-constraining side (FIG. 7). A pair of traveling wheels 23 (FIG. 8) are vertically attached while being held, and these traveling wheels 23 are in rolling contact with the upper planes of the corresponding rails 3a and 3b, respectively.
On the restraint side, restraint wheels 24 are horizontally attached to the lower flange portions on both sides of each holding frame 22, and these restraint wheels 24 are in rolling contact with the vertical side portions of the corresponding rails 3a and 3b, respectively.
As shown in FIG. 8, the restraining wheel 24 on the restraining side is located on the lower side between the pair of running wheels 23. Thus, the pair of running wheels 23, 23 and one restraining wheel 24 are connected to each other. The set is attached to two places on one side of the upper and lower cover lids 2a and 2b.
On the non-restraining side, the pair of traveling wheels 23, 23 are attached to two locations on the other side of the upper and lower cover lids 2a, 2b.
上下の覆蓋2a,2bの両側部の脚部20,21は、各保持枠22,22aへねじで固定されていても実施することができるが、覆蓋2a,2bのスパン(幅)が大きく、あるいはそれらの荷重が大きいことにより撓み(水槽1の幅方向の撓み)量が大きい場合は、それぞれ撓み追随手段7を介して対応する各保持枠22,22aの上に設置するのが好ましい。
撓み追随手段7は、脚部20,21の下部を対応する保持枠22,22aの上部ヘ長さ方向に沿う水平な軸で連結する構成でもよいが、覆蓋2a,2bは重量が大きいので以下のように構成するのが好ましい。
The leg portions 20 and 21 on both sides of the upper and lower cover lids 2a and 2b can be implemented even if they are fixed to the holding frames 22 and 22a with screws, but the span (width) of the cover lids 2a and 2b is large. Alternatively, when the amount of bending (the bending in the width direction of the water tank 1) is large due to the large load, it is preferable to install on the corresponding holding frames 22, 22a via the bending tracking means 7, respectively.
The bend following means 7 may be configured to connect the lower portions of the leg portions 20 and 21 with a horizontal axis along the longitudinal direction of the upper portions of the corresponding holding frames 22 and 22a. However, the cover lids 2a and 2b are heavy and are described below. It is preferable to configure as follows.
図8において、70,70は、覆蓋2a,2bの撓みによりそれらの側端部が傾いたときに車輪23,24へ影響を与えないように、対応する脚部20,21を追随させる追随主体であり、追随受部材70,70の上部は蓋2a,2bの長さ方向(水槽1の長さ方向)と直交する断面において円弧状に形成されている。
この実施形態において追随主体70,70は車輪状であり、保持枠22の上部に直立するように固定された対の支持板72,72の間ヘ各軸73を介して回転自在に支持され、それらの上部は受板71を介して対応する脚部20,21の下面へ接触している。
保持枠22は、対応する脚部20,21の下面へ垂直に固定された規制板74,74が両端部の支持板72,72へ接触していることにより、対応する脚部20,21に対して走行方向ヘずれ動かないように規制されている。この規制板74,74は、前記各軸73が回転自在に貫通して対応する脚部20,21に対して覆蓋2a,2bの幅方向にはずれ動かないように規制されている。
対の追随主体70,70は、前述のように対応する各車輪23,24及び対応する保持枠22,22aとセットになっているので、各覆蓋2a,2b片側の端部へ所定の間隔を置いて二対設置される。
In FIG. 8, reference numerals 70 and 70 denote followers that follow the corresponding leg portions 20 and 21 so as not to affect the wheels 23 and 24 when the side ends thereof are inclined due to the bending of the cover lids 2a and 2b. The upper portions of the tracking members 70, 70 are formed in an arc shape in a cross section orthogonal to the length direction of the lids 2a, 2b (length direction of the water tank 1).
In this embodiment, the following main bodies 70 and 70 are wheel-shaped, and are rotatably supported through respective shafts 73 between a pair of support plates 72 and 72 fixed so as to stand upright on the upper portion of the holding frame 22. Their upper portions are in contact with the lower surfaces of the corresponding leg portions 20 and 21 via the receiving plate 71.
The holding frame 22 has the restriction plates 74 and 74 fixed vertically to the lower surfaces of the corresponding leg portions 20 and 21 in contact with the support plates 72 and 72 at both ends. On the other hand, it is regulated not to move in the running direction. The restricting plates 74 and 74 are restricted so as not to move in the width direction of the cover lids 2a and 2b with respect to the corresponding leg portions 20 and 21 through which the respective shafts 73 are rotatably passed.
Since the pair of following main bodies 70 and 70 are set with the corresponding wheels 23 and 24 and the corresponding holding frames 22 and 22a as described above, a predetermined interval is provided to the end portions of the respective cover lids 2a and 2b. Two pairs are installed.
上記構成において、覆蓋2a,2bが撓むことによりそれらの端部が図6,7の左右方向に傾く(若干傾く)と、追随主体70,70が前記の傾き量に応じて回転することにより、覆蓋2a,2bを追随させる。
上記構成において、規制板74,74は図示の位置にあるのが好ましいが、保持枠22が走行方向に動かないように規制する状態であれば図示の位置に限定されない。
追随主体70,70は回転する車輪により構成されているが、受板71との接触部が断面円弧状であれば車輪状である必要はない。主体70,70は回転自在であることが好ましいが、回転せずに受板に接触しているだけでも実施することができる。例えば、保持枠22の上部へ固定した主体70,70の上部を断面円弧状に形成し、受板71の下面を主体70の上部の円弧よりもやや大きい凹円弧状に形成して、主体70の受板71との接触部が、覆蓋2a,2bの端部の傾きに応じて回動するように構成することもできる。
また、前記いずれの構成においても、追随主体70は対応する脚部20,21の下面へとり付けても実施することができる。
In the above configuration, when the cover lids 2a and 2b are bent and their end portions tilt (slightly tilt) in the left-right direction in FIGS. 6 and 7, the following main bodies 70 and 70 rotate according to the tilt amount. The cover lids 2a and 2b are made to follow.
In the above configuration, the restricting plates 74 are preferably located at the illustrated positions, but are not limited to the illustrated positions as long as the holding frame 22 is restricted so as not to move in the traveling direction.
The following main bodies 70 and 70 are constituted by rotating wheels, but need not be wheel-shaped if the contact portion with the receiving plate 71 has a circular arc cross section. The main bodies 70 and 70 are preferably rotatable, but the present invention can be carried out only by contacting the receiving plate without rotating. For example, the upper portions of the main bodies 70 fixed to the upper portion of the holding frame 22 are formed in an arc shape in cross section, and the lower surface of the receiving plate 71 is formed in a concave arc shape slightly larger than the arc in the upper portion of the main body 70. The contact portion with the receiving plate 71 can be configured to rotate according to the inclination of the end portions of the cover lids 2a and 2b.
In any of the configurations described above, the following main body 70 can be implemented by being attached to the lower surfaces of the corresponding leg portions 20 and 21.
前述のように、撓み追随手段7は不可欠な構成部分ではなく、覆蓋2a,2bの重量や幅その他の条件によっては、蓋2a,2bの脚部20,21を保持枠22の上部へねじ等で固定することができる。例えば、覆蓋2a,2bを構成する主部材がアルミ合金等の部材である場合、覆蓋2a,2bの幅が15mを超えない場合には撓み追随手段7はほとんど必要がない。   As described above, the bending follower 7 is not an indispensable component, and depending on the weight, width, and other conditions of the cover lids 2a and 2b, the legs 20 and 21 of the lids 2a and 2b are screwed to the upper portion of the holding frame 22 or the like. It can be fixed with. For example, when the main member constituting the cover lids 2a and 2b is a member such as an aluminum alloy, if the width of the cover lids 2a and 2b does not exceed 15 m, the bending tracking means 7 is almost unnecessary.
図7で示すように、非拘束側において、各保持枠22aの下部の一方叉は両方のフランジ部には、覆蓋2a,2bが所定量浮上したときレール3(3a,3b)の主部に引っ掛る引っ掛り部61を有する浮上がり防止具6が取り付けられている。
この浮上がり防止具6は、拘束側のレール3a,3bにも設置するのが好ましい。
第2実施形態の覆蓋装置の他の構成や作用,効果は、第1実施形態の覆蓋装置と同様であるのでそれらの説明は省略する。
As shown in FIG. 7, on the non-restraining side, one or both flanges at the bottom of each holding frame 22a are placed on the main part of the rail 3 (3a, 3b) when the cover lids 2a, 2b are lifted by a predetermined amount. A lifting prevention tool 6 having a hooking portion 61 to be hooked is attached.
This lifting prevention tool 6 is preferably installed also on the restraining side rails 3a and 3b.
Other configurations, operations, and effects of the cover device according to the second embodiment are the same as those of the cover device according to the first embodiment, and a description thereof will be omitted.
第3実施形態
図9は第3実施形態を示す部分断面図であり、この実施形態においては、レール3a,3bの主部を断面ほぼ逆三角形に形成するとともに、この形状に対応して保持枠22(22a)のフランジ部を傾斜するように形成している。
したがって、保持枠22のU字状部内に取り付けた走行車輪23をレール3a,3bの上部の平面へ転接させ、保持枠22の各フランジ部ヘ傾斜状に取り付けた拘束車輪24をレール3a,3bの側部の傾斜面ヘ転接させている。
この実施形態では、拘束側には浮上がり防止具を必要としない利点があるが、その他の構成や作用,効果は第1実施形態の装置と同様である。
Third Embodiment FIG. 9 is a partial cross-sectional view showing a third embodiment. In this embodiment, the main parts of the rails 3a and 3b are formed in a substantially inverted triangle cross section, and a holding frame corresponding to this shape. 22 (22a) is formed so as to be inclined.
Therefore, the traveling wheel 23 attached in the U-shaped part of the holding frame 22 is brought into rolling contact with the upper plane of the rails 3a and 3b, and the restraining wheel 24 attached in an inclined manner to each flange part of the holding frame 22 is attached to the rail 3a, It is brought into rolling contact with the inclined surface of the side portion 3b.
In this embodiment, there is an advantage that the restraining side does not require a lifting prevention tool, but other configurations, operations, and effects are the same as those of the apparatus of the first embodiment.
