Description

本発明は、昇降柵に関する。   The present invention relates to a lifting fence.

電力会社では、緊急用発電設備としてエンクロージャー式等の発電装置を用意している。この発電装置は、長尺な筺状のケーシング内部に発電機器が備えられている。ケーシングには、内部の発電装置の点検等のために複数の扉が設置されている。扉は地上から高い箇所に位置していることから、ケーシングに沿って点検用の歩廊が中空に浮くように配置される。   An electric power company prepares a power generation device of an enclosure type or the like as emergency power generation equipment. In this power generation device, a power generation device is provided inside a long casing. The casing is provided with a plurality of doors for checking the internal power generation device and the like. Since the door is located high above the ground, the inspection corridor is arranged so as to float in the air along the casing.

ケーシング内部には発電装置が詰まっており、人が入れるほどの隙間がないため、作業者はケーシングの中に入って発電装置の点検を行うことは難しい。このため、歩廊を足場にし、扉を開けた状態で、ケーシング内部の発電装置の点検を行うことになる。歩廊には柵が設置されていないこと、そして、歩廊の幅が狭いことから、点検中の作業者には転落の危険性が伴う。このため、作業者が転落しないよう、歩廊に設置する柵が望まれている。   Since the power generator is clogged inside the casing and there is no gap enough for a person to enter, it is difficult for an operator to enter the casing and inspect the power generator. For this reason, the power generator inside the casing is inspected with the walkway as a foothold and the door opened. The lack of fences in the walkway and the narrow width of the walkway poses a risk of falling for workers under inspection. For this reason, a fence to be installed in the side corridor is desired so that the worker does not fall.

しかしながら、扉が開き戸で、扉の幅が歩廊の幅よりも大きい場合、柵を歩廊に固定してしまうと、扉が柵に干渉して開閉できない。その結果、筺体内部の発電装置の点検ができなくなってしまう。このため、扉の開閉の際に扉に干渉しない可動式の柵が望まれている。可動式の柵として、例えば、特許文献１、２等の柵がある。   However, if the door is a hinged door and the width of the door is larger than the width of the corridor, if the fence is fixed to the corridor, the door interferes with the fence and cannot be opened or closed. As a result, it becomes impossible to inspect the power generation device inside the housing. Therefore, a movable fence that does not interfere with the door when the door is opened and closed is desired. As a movable fence, for example, there are fences disclosed in Patent Documents 1 and 2.

図を参照しつつ、本実施の形態に係る昇降柵について説明する。昇降柵１は、図１（Ａ）、図１（Ｂ）に示すように、柵１０と支持部材２０と固定部材３０とを備える。   The elevating fence according to the present embodiment will be described with reference to the drawings. The lifting fence 1 includes a fence 10, a support member 20, and a fixing member 30, as shown in FIGS. 1A and 1B.

柵１０は、第１の支柱１１、第２の支柱１２、縦材１３、上横材１４ａ、下横材１４ｂ、係止部材１５を備えている。   The fence 10 includes a first support 11, a second support 12, a vertical member 13, an upper cross member 14a, a lower cross member 14b, and a locking member 15.

第１の支柱１１は、昇降自在に支持部材２０に差し込まれる部材である。第１の支柱１１と第２の支柱１２とは、隣接して並行に配置されている。第１の支柱１１の側面から第２の支柱１２に向けて、棒状の係止部材１５が突出しており、第１の支柱１１と第２の支柱１２とは下部で係止部材１５により連結されている。また、係止部材１５は、第１の支柱１１から第２の支柱１２の逆方向にも突出している。   The first support 11 is a member that is inserted into the support member 20 so as to be able to move up and down. The first support 11 and the second support 12 are adjacently arranged in parallel. A rod-shaped locking member 15 protrudes from the side surface of the first column 11 toward the second column 12, and the first column 11 and the second column 12 are connected by the locking member 15 at the lower part. ing. The locking member 15 also protrudes from the first support 11 in the opposite direction of the second support 12.

第１の支柱１１、第２の支柱１２及び係止部材１５は、両側に対称に２組配置されている。   The first support 11, the second support 12, and the locking member 15 are symmetrically arranged on both sides in two sets.

第２の支柱１２同士の間には、縦材１３が２本配置されており、上下に配置された上横材１４ａ、下横材１４ｂで連結されており、柵１０は一体的に形成されている。なお、縦材１３はより多くあっても少なくてもよい。また、第２の支柱１２同士の間に、更に横材が配置されていてもよい。   Two vertical members 13 are arranged between the second columns 12, and are connected by upper and lower members 14a and 14b arranged vertically, and the fence 10 is formed integrally. ing. The number of the vertical members 13 may be more or less. In addition, a cross member may be further arranged between the second columns 12.

支持部材２０は、第１の支柱１１が昇降可能に挿入される筒状の部材である。支持部材２０の奥行き（図１（Ｂ）のＤ１）は、例えば、柵１０の第１の支柱１１の径（図１（Ｂ）のＤ２）の２倍程度である。また、支持部材２０には、案内溝２１が形成されている。案内溝２１は、図１（Ｂ）に示すように、逆Ｊ字状であり、支持部材２０の下部が開口し、そこから支持部材２０の長手方向に略垂直に延びて折り返した後、閉じられた溝である。案内溝２１は、柵１０の上昇、下降において、柵１０の係止部材１５が進入するとともに、係止部材１５を係止する役割を有する。案内溝２１は、支持部材２０の第１の支柱１１と第２の支柱１２で挟まれる側面及び反対側の側面に対称に形成されており、第１の支柱１１の両側から突出する係止部材１５の双方がそれぞれの案内溝２１に進入する。   The support member 20 is a cylindrical member into which the first support 11 is inserted so as to be able to move up and down. The depth of the support member 20 (D1 in FIG. 1B) is, for example, about twice the diameter of the first support 11 of the fence 10 (D2 in FIG. 1B). Further, a guide groove 21 is formed in the support member 20. As shown in FIG. 1 (B), the guide groove 21 has an inverted J-shape. The lower part of the support member 20 is opened, extends substantially perpendicularly to the longitudinal direction of the support member 20, and is folded back. Groove. The guide groove 21 has a role of locking the locking member 15 while the locking member 15 of the rail 10 enters when the rail 10 is raised or lowered. The guide groove 21 is formed symmetrically on the side face between the first support 11 and the second support 12 of the support member 20 and on the opposite side, and a locking member protruding from both sides of the first support 11. 15 enter the respective guide grooves 21.

固定部材３０は、中空に浮くように設定されたグレーチング等の歩廊に取り付けられ、支持部材２０を支持する部材である。固定部材３０は、歩廊に取り付けられ、支持部材２０を支持可能であれば、どのような形態であってもよい。ここでは、固定部材３０は、取付部３１と締結具３２を有しており、歩廊を取付部３１及び締結具３２で狭持する形態である。   The fixing member 30 is a member that is attached to a walkway such as a grating that is set so as to float in the air and that supports the support member 20. The fixing member 30 may be in any form as long as it can be attached to the walkway and can support the support member 20. Here, the fixing member 30 has a mounting portion 31 and a fastener 32, and has a form in which the corridor is held between the mounting portion 31 and the fastener 32.

また、固定部材３０の上端と支持部材２０の上端との長さ（図１（Ｂ）のＤ３）は、上横材１４ａの径（図１（Ｂ）のＤ４）よりも長く設定される。   The length (D3 in FIG. 1B) between the upper end of the fixing member 30 and the upper end of the support member 20 is set longer than the diameter (D4 in FIG. 1B) of the upper cross member 14a.

続いて、図２〜図５を参照して、昇降柵１の動作について説明する。図２は、柵１０が下降して係止している状態を示している。この状態では、柵１０の上横柱１４ａが支持部材２０の上端に当接しており、柵１０はこれ以上下降しない。   Subsequently, the operation of the lifting fence 1 will be described with reference to FIGS. FIG. 2 shows a state where the fence 10 is lowered and locked. In this state, the upper horizontal column 14a of the fence 10 is in contact with the upper end of the support member 20, and the fence 10 does not descend any more.

図２の状態から、柵１０を引き上げていくと、図３に示すように、係止部材１５が支持部材２０の案内溝２１の開口箇所から進入し、通過してゆく。   When the fence 10 is pulled up from the state shown in FIG. 2, the locking member 15 enters from the opening of the guide groove 21 of the support member 20 and passes through as shown in FIG.

係止部材１５が案内溝２１の折り返し部まで達した後、図４に示すように、柵１０の上部を、図４（Ｂ）における紙面上、左方向（固定部材３０の反対方向）に力を加えることで、係止部材１５が固定部材３０側へ移動し、案内溝２１の折り返し部２２で折り返される。   After the locking member 15 reaches the folded portion of the guide groove 21, as shown in FIG. 4, the upper part of the fence 10 is moved leftward (in the opposite direction to the fixing member 30) on the paper surface of FIG. Is added, the locking member 15 moves to the fixing member 30 side, and is folded at the folded portion 22 of the guide groove 21.

そして、案内溝２１の折り返し部２２で係止部材１５が折り返された後、柵１０を下降させると、図５に示すように、係止部材１５が案内溝２１の閉口箇所で係止される。これにより、柵１０が支持部材２０、固定部材３０から上方へ突出した状態で固定される。   Then, when the fence 10 is lowered after the locking member 15 is folded back at the folded portion 22 of the guide groove 21, the locking member 15 is locked at the closed position of the guide groove 21 as shown in FIG. . Thereby, the fence 10 is fixed in a state where it protrudes upward from the support member 20 and the fixing member 30.

柵１０を下降させる場合、上記と逆の手順で行うことで、図２に示す元の状態（柵が下降した状態）にすることができる。   When the fence 10 is lowered, the original state shown in FIG. 2 (the state in which the fence is lowered) can be obtained by performing the above procedure in reverse.

図６、図７に、扉ＤＲを有するケーシングＣＡに沿って設置された歩廊ＳＴに、昇降柵１が設置された状態を示している。なお、ここでは、緊急用の発電装置を内部に備えるケーシングＣＡに沿って設置された歩廊ＳＴに昇降柵１が設置された例を示している。   FIGS. 6 and 7 show a state in which the elevating fence 1 is installed in the corridor ST installed along the casing CA having the door DR. Here, an example is shown in which the elevating fence 1 is installed in a corridor ST installed along a casing CA provided with an emergency power generation device therein.

柵１０が下降した状態で扉ＤＲを開き、扉ＤＲを開いた状態で柵１０を上昇させて固定し、扉ＤＲを開いた状態で、作業者は歩廊ＳＴに立ったまま、ケーシングＣＡ内部の発電装置を点検する。柵１０が上昇しているので、歩廊ＳＴに立って点検等を行う作業者は、柵１０によって転落することを免れ、安心して点検作業を行うことができる。   With the fence 10 lowered, the door DR is opened, the fence 10 is raised and fixed with the door DR open, and with the door DR open, the worker stands inside the corridor ST while standing inside the corridor ST. Check the generator set. Since the fence 10 is raised, the worker standing in the corridor ST and performing an inspection or the like is prevented from falling down by the fence 10 and can perform the inspection work with confidence.

そして、昇降柵１は簡易な構成であり、柵１０の昇降を容易に行い得るので、扉ＤＲの開閉の都度、作業者は柵１０を昇降させるのに手間や負担が掛からない。   And since the raising / lowering fence 1 is a simple structure and can raise / lower the fence 10 easily, every time opening / closing of the door DR, an operator does not take trouble and load to raise / lower the fence 10.

また、柵１０を下降させた状態において、柵１０の上横材１４ａが固定部材３０の上方へ突出しないので、扉ＤＲを開閉する際に、扉ＤＲが柵１０に干渉しない。   Further, when the fence 10 is lowered, the upper cross member 14a of the fence 10 does not protrude above the fixing member 30, so that the door DR does not interfere with the fence 10 when the door DR is opened and closed.

また、ケーシングＣＡに複数の扉ＤＲが隣接して配置されている場合、柵１０の幅は、扉ＤＲが開いた状態で扉ＤＲ同士の幅よりも狭く設定されている。昇降柵１０同士で開いた扉ＤＲを挟むようになることから、開いている扉ＤＲが不意に閉じて、作業者が扉ＤＲに挟まれることも抑えられる。   When a plurality of doors DR are arranged adjacent to the casing CA, the width of the fence 10 is set to be smaller than the width of the doors DR when the doors DR are open. Since the open door DR is sandwiched between the lifting fences 10, the open door DR is unexpectedly closed, and it is also possible to prevent the worker from being sandwiched by the door DR.

なお、図８に示すように、柵１０には、柵１０を昇降させる際に持つ取っ手１６が設置されていてもよい。ここでは、上横材１４ａに取っ手１６が設置された例を示している。   As illustrated in FIG. 8, a handle 16 that is held when the fence 10 is moved up and down may be installed on the fence 10. Here, an example in which the handle 16 is installed on the upper cross member 14a is shown.

また、図８に示すように、係止部材１５で第１の支柱１１と第２の支柱１２とが連結されていなくてもよい。この場合、柵１０が歪まないよう、柵１０は十分な機械的強度を有する素材から構成されることが好ましい。   In addition, as shown in FIG. 8, the first support 11 and the second support 12 may not be connected by the locking member 15. In this case, the fence 10 is preferably made of a material having sufficient mechanical strength so that the fence 10 is not distorted.

また、図８に示すように、係止部材１５が第１の支柱１１の両側からではなく、一方向のみ突出した形態であってもよい。この場合、第１の支柱１１から係止部材１５が突出していない側に位置する支持部材２０の側面には、案内溝２１が形成されていなくてもよい。   Further, as shown in FIG. 8, the locking member 15 may be configured to protrude in only one direction, not from both sides of the first support 11. In this case, the guide groove 21 may not be formed on the side surface of the support member 20 located on the side where the locking member 15 does not protrude from the first support 11.

また、柵１０を引き上げた後、柵１０の上部を固定部材３０側へ係止部材１５が案内溝２１の折り返し部２２で折り返される形態について説明したが、図９（Ａ）に示すように、案内溝２１が上記とは水平方向に逆向きに形成されており、固定部材３０側に力を加え、係止部材１５が固定部材３０の逆方向へ移動し、案内溝２１の折り返し部２２で折り返される形態であってもよい。   In addition, a description has been given of a mode in which the locking member 15 is folded back at the folded portion 22 of the guide groove 21 by raising the fence 10 to the fixing member 30 side after the fence 10 is pulled up, as shown in FIG. The guide groove 21 is formed in a direction opposite to the above in the horizontal direction, applies a force to the fixing member 30 side, the locking member 15 moves in the opposite direction of the fixing member 30, and the guide groove 21 It may be folded back.

更には、図９（Ｂ）に示すように、案内溝２１が略Ｔ字状に形成されており、係止部材１５が固定部材３０の方向、及び、固定部材３０の逆方向へ、どちらへも移動可能な形態であってもよい。   Further, as shown in FIG. 9 (B), the guide groove 21 is formed in a substantially T-shape, and the locking member 15 is moved in either the direction of the fixing member 30 or the direction opposite to the fixing member 30. May be movable.
