Description

本発明は、ロープブレーキ装置であって、ロープブレーキの伸長に際して縮小するループを形成する少なくとも１つの鋼ロープを備えており、鋼ロープが、ロープブレーキの伸長状態で、列を成して配置された複数の孔を備えたブレーキプレートを通って、１孔から別の１孔にそれぞれブレーキプレートの１側から交互に案内されており、かつ１列の最後位の孔から該列に隣接する列の最前位の孔に向かって、ループを成すように後退案内されている形式のものに関する。   The present invention is a rope brake device comprising at least one steel rope forming a loop that contracts when the rope brake is extended, and the steel ropes are arranged in a row in the extended state of the rope brake. Through the brake plate provided with a plurality of holes, and alternately guided from one side of the brake plate to the other side from one side of the brake plate and adjacent to the row from the last hole in one row It is related with the thing of the type which is backwardly guided so that a loop may be formed toward the foremost hole.

このような形式のロープブレーキ装置は、スイス国特許第６６８３００号明細書から公知である。このようなロープブレーキ装置では、ブレーキプレートに、それぞれ平行の２列の孔が設けられており、孔列を通って、制動作用を及ぼす鋼ロープが案内されており、伸長する際に引っ張られる。鋼ロープは、第１列の最後位の孔から第２列の最前位の孔に後退案内され、この場合ループを形成する。ループの大きさは、ロープブレーキの伸長区間を規定する。雪崩、落石または落木用の捕集ネットの規定の装置では、ループの大きな寸法を必要とする、ロープブレーキの伸長区間が所望される。ロープブレーキは、捕集ネットの設置場所に向かって多くの場合道のない地形を搬送する必要がある。この場合過大なサイズのループは邪魔になる。このような難点に対しては、所望の伸長区間を有する比較的大きなループを備えたロープブレーキに代わって、比較的小さなループを有する２列に配置されたロープブレーキを選択することによって克服されるが、しかしながらこれによって経済的な欠点が高まる。
スイス国特許第６６８３００号明細書 A rope brake device of this type is known from Swiss Patent No. 668300. In such a rope brake device, the brake plate is provided with two parallel rows of holes, and a steel rope that exerts a braking action is guided through the hole rows and is pulled when it is extended. The steel rope is retracted from the last hole in the first row to the foremost hole in the second row, forming a loop in this case. The size of the loop defines the extension section of the rope brake. In a defined apparatus for avalanche, fallen rock or fallen net collection, an extended section of the rope brake is required which requires large dimensions of the loop. Rope brakes often need to carry roadless terrain towards the location of the collection net. In this case, an oversized loop is an obstacle. This difficulty can be overcome by selecting a rope brake arranged in two rows with a relatively small loop instead of a rope brake with a relatively large loop having the desired extension section. However, this raises economic disadvantages.
Swiss Patent No. 668300

したがって本発明の課題は、冒頭で述べたような形式のロープブレーキ装置を改良して、実際に雪崩、落石または落木用に存在するあらゆる捕集ネットにとって十分な伸長区間を有しており、道のない地形でも簡単に搬送可能であり、しかも経済的な利点を有するようなものを提供することである。   The object of the present invention is therefore to improve a rope brake device of the type mentioned at the outset and to have a sufficient extension section for any collection net that actually exists for avalanches, falling rocks or fallen trees, The object is to provide a vehicle that can be easily transported even on terrain without any obstacles and that has an economic advantage.

この課題を解決するための本発明の装置によれば、ブレーキプレートが、少なくとも３列の孔を有しており、ブレーキの伸長に際して縮小する少なくとも２つのループが設けられている。   According to the device of the present invention for solving this problem, the brake plate has at least three rows of holes, and is provided with at least two loops that contract when the brake is extended.

本発明の構成によれば、ロープブレーキの伸長区間を複数のループに分割することによって、ループは十分な伸長区間で小さく維持することができる。比較的小さなループを有するロープブレーキの搬送性は、道のない地形でも有利である。もちろんロープブレーキの経済的な利点も得られる。   According to the configuration of the present invention, by dividing the extension section of the rope brake into a plurality of loops, the loop can be kept small in a sufficient extension section. The transportability of a rope brake with a relatively small loop is advantageous even on roadless terrain. Of course, the economic advantage of rope brakes can also be obtained.

ブレーキプレートに設けられた孔列は、有利には互いにずらして配置されている。ブレーキプレートにおける孔がずらして配置されていることによって、ブレーキプレートの寸法は、所望の機械強さを維持しつつ、小さく維持することができる。   The hole rows provided in the brake plate are preferably arranged offset from one another. Because the holes in the brake plate are offset, the size of the brake plate can be kept small while maintaining the desired mechanical strength.

次に本発明の実施の形態を図示の実施例を用いて詳しく説明する。   Next, embodiments of the present invention will be described in detail using the illustrated examples.

図１および図２に示したロープブレーキ装置では、制動力を及ぼす鋼ロープ１がブレーキプレート２を通って案内されている。鋼ロープ１は、ブレーキプレート２に設けられた各列の孔３を通って、１孔３から別の１孔３へと交互にブレーキプレート２のそれぞれ別の側から（つまり交互に貫通案内方向を変えて）案内されている。鋼ロープ１は、抵抗下で（つまり抵抗作用を及ぼして）孔３を通って引っ張ることができ、そうして制動力を形成する。孔３は、ブレーキプレート２に３列で配置されている。鋼ロープ１は、第１列の最後位の孔から隣接する第２列の最前位の孔に、第１のループ４を形成しつつ後退案内（逆方向案内）されている。第２列の最後位の孔３から、鋼ロープ１は、再び次に隣接する第３列の最前位の孔３に後退案内されている。そのようにして後退案内された鋼ロープ１は第２のループ４を形成する。鋼ロープの伸長区間は、両方のループ４におけるロープ長さの合計によって所与されている。鋼ロープ１の、図１においてシャックル５で示した接続箇所に接続された支持ロープ６に過剰な引張荷重がかかる場合、鋼ロープ１は、ブレーキプレート２の孔３を通って制動作用を及ぼしつつ引っ張られ、そうして過負荷および接続された支持ロープ６の破断が回避される。雪崩、落石または落木を捕集するネットの保持ロープとして使用される支持ロープ６のそのような過剰な引張荷重は、使用場所で生じる恐れがある。   In the rope brake device shown in FIGS. 1 and 2, a steel rope 1 that exerts a braking force is guided through a brake plate 2. The steel rope 1 passes through each row of holes 3 provided in the brake plate 2 and alternately passes from one hole 3 to another hole 3 from each other side of the brake plate 2 (that is, alternately through and guiding directions). Is changed). The steel rope 1 can be pulled through the hole 3 under resistance (ie exerting a resistance action), thus creating a braking force. The holes 3 are arranged in three rows on the brake plate 2. The steel rope 1 is backwardly guided (reversely guided) while forming a first loop 4 from the last hole in the first row to the frontmost hole in the second row adjacent thereto. From the last hole 3 in the second row, the steel rope 1 is again guided back to the foremost hole 3 in the next adjacent third row. The steel rope 1 guided backwards in this way forms a second loop 4. The extension section of the steel rope is given by the sum of the rope lengths in both loops 4. When an excessive tensile load is applied to the support rope 6 connected to the connection portion indicated by the shackle 5 in FIG. 1 of the steel rope 1, the steel rope 1 exerts a braking action through the hole 3 of the brake plate 2. Pulling is thus avoided and overloading and breaking of the connected support rope 6 is avoided. Such excessive tensile load of the support rope 6 used as a net holding rope for collecting avalanches, fallen rocks or fallen trees may occur at the place of use.

ロープブレーキ装置の考えられる伸長区間を単個のブレーキプレート２における複数のループ４に分配することによって、経済的に有利な構造が得られる。道のない地形でのロープブレーキの良好な搬送性の観点から、ループ４の直径は比較的小さく維持するが、伸長区間は制限されないよう所望される。このような条件は、列状に配置された２つまたは３つ以上のループ４をブレーキプレート２に形成することによって良好に満たすことができる。   By distributing the possible extension sections of the rope brake device to a plurality of loops 4 in a single brake plate 2, an economically advantageous structure is obtained. From the viewpoint of good transportability of the rope brake on roadless terrain, it is desirable that the diameter of the loop 4 is kept relatively small, but the extension section is not limited. Such a condition can be satisfactorily satisfied by forming two or more loops 4 arranged in a row on the brake plate 2.

ブレーキプレート２における孔３の列は互いにずらして配置されている。このような構成手段によって、ブレーキプレート２は有利な形式で利用することができる。ブレーキプレート２の所望の機械強さは、追加的な手段を設けることなく維持することができる。   The rows of holes 3 in the brake plate 2 are shifted from each other. With such a construction, the brake plate 2 can be used in an advantageous manner. The desired mechanical strength of the brake plate 2 can be maintained without providing additional means.
