Description

本発明は、例えば油圧ショベル等の建設機械の機体に設けられるステップ等の滑り止め構造に関する。   The present invention relates to a non-slip structure such as a step provided in a body of a construction machine such as a hydraulic excavator.

油圧ショベル等の建設機械では、通常、作業者が機体に乗降あるいはエンジンやポンプ等を点検整備できるように機体にステップが設けられている。しかしながら、一般に、ステップの足場となる基板は、鋼板や鉄板から形成されており、作業者がステップに乗降あるいはその上を歩行するとき、あるいはステップに乗って前記点検・整備するときなどに、滑りやすいという問題があった。そこで、通常、作業者の足場となるステップの基板には、ノンスリップテープ等の滑り止めを貼付した滑り止め構造や、図３に示すように鋼板や鉄板に鋭利な突起を設けた滑り止め構造が採用されている。   In a construction machine such as a hydraulic excavator, a step is usually provided in the machine body so that an operator can get on and off the machine body or inspect and maintain an engine, a pump, and the like. However, in general, the substrate that serves as a scaffold for the step is formed of a steel plate or an iron plate, and slips when an operator gets on or off the step or walks on the step, or when the step is carried out for inspection and maintenance. There was a problem that it was easy. Therefore, usually, the step board that serves as a scaffold for the worker has a non-slip structure with a non-slip tape or other anti-slip structure, or a non-slip structure with sharp protrusions on a steel plate or iron plate as shown in FIG. It has been adopted.

図３に基づいて従来の建設機械の滑り止め構造を説明すると、符号１はステップを支持するステップ支持部材であり、ステップ支持部材１には、ステップの足場を形成する基板２１が適宜の手段によって支持されている。基板２１は適宜厚さの鋼板を矩形に成形して塗装を施したものであり、基板２１の作業者が乗る部分には、バーリング加工等によって形成された複数のバーリング孔２２が穿設されている。バーリング孔２２の周縁には、全て同一面側に向けて同一高さで突出する周縁フランジ（突起）２２ａが形成されている。図３に示す滑り止め構造によれば、作業者が基板２１上に乗ると、周縁フランジ２２ａの先端が作業靴の靴底に食い込むとともに、バーリング孔２２内に靴底のブロックパターンが入り込み、靴底と周縁フランジ２２ａとが噛み合うように係合し、この係合によって、作業者の作業靴が基板２１上でずれることがなくなり、機体上面において作業者が安全に作業を行うことできるようになっている。図３に示すバーリング加工を採用した建設機械の滑り止め構造に関連する先行技術文献としては、後掲する特許文献１、２がある。   Referring to FIG. 3, a conventional anti-slip structure for a construction machine will be described. Reference numeral 1 denotes a step support member for supporting a step. It is supported. The substrate 21 is formed by coating a steel plate having a suitable thickness into a rectangular shape, and a plurality of burring holes 22 formed by burring processing or the like are formed in a portion of the substrate 21 on which an operator rides. Yes. A peripheral flange (protrusion) 22a is formed on the peripheral edge of the burring hole 22 so as to protrude all at the same height toward the same surface. According to the anti-slip structure shown in FIG. 3, when the operator gets on the substrate 21, the tip of the peripheral flange 22a bites into the shoe sole of the work shoe, and the block pattern of the shoe sole enters the burring hole 22, The bottom and the peripheral flange 22a are engaged with each other so that the operator's work shoes are not displaced on the substrate 21, and the worker can safely work on the upper surface of the machine body. ing. As prior art documents related to the anti-slip structure of a construction machine employing the burring process shown in FIG.

前述したノンスリップテープを貼付した滑り止め部材は、雨や雪のなどに対しては滑り止めの効果を十分に発揮できず、また、耐候性に乏しく劣化し易く、耐久性や信頼性に乏しいという問題があった。   The non-slip member with the non-slip tape mentioned above cannot fully exhibit the anti-slipping effect against rain or snow, etc., and it is poor in weather resistance and easily deteriorated, and has poor durability and reliability. There was a problem.

また、図３に示す鋼板にバーリング加工による突起を設けた滑り止め構造は、前記突起に作業者の靴底が噛み合い係合するため、雨や雪などの場合にも、十分な滑り止め効果を発揮することができる。しかしながら、図３に示す滑り止め構造は、ステップの基板を形成する鋼板や鉄板等に鋭利な突起を設けた構造であるため、作業者がステップの基板に手やひざ等をついたとき、前記突起によって怪我をするおそれがあり、作業者の安全が十分に確保できないという問題があった。   Further, the anti-slip structure provided with the burring projection on the steel plate shown in FIG. 3 has a sufficient anti-slip effect even in the case of rain or snow because the shoe sole of the operator meshes with and engages with the projection. It can be demonstrated. However, since the anti-slip structure shown in FIG. 3 is a structure in which sharp protrusions are provided on a steel plate or an iron plate that forms the step substrate, when the operator puts a hand or knee on the step substrate, There was a risk of injury from the protrusion, and there was a problem that the safety of the worker could not be sufficiently secured.

本発明の課題は、雨や雪などに対しても十分な滑り止め効果があり、かつ、ステップの基板に作業者が手やひざ等をついても怪我をすることがなく、安全に作業をすることができる建設機械の滑り止め構造を提供することにある。   It is an object of the present invention to have a sufficient anti-slip effect against rain and snow, etc., and even if an operator puts a hand or knee on the step board, the work can be safely performed. An object is to provide a non-slip structure of a construction machine.

本発明は、前記課題を達成するために、足場となるステップと、該ステップの上面に取り付けられた滑り止め部材とを備えた建設機械の滑り止め構造において、前記ステップに段差を形成するとともに、前記滑り止め部材を前記ステップに設けた段差を埋め、かつ表面に多数の凸部を設けたゴムプレートから構成したものである。   In order to achieve the above object, the present invention provides a non-slip structure for a construction machine including a step serving as a scaffold and an anti-slip member attached to the upper surface of the step, and forming a step in the step. The anti-slip member is composed of a rubber plate that fills the step provided in the step and has a large number of convex portions on the surface.

本発明によれば、足場となる基板の上に設置される滑り止め部材を、表面に多数の凸部を設けたゴムプレートから構成したので、該凸部によって雨や雪が降っている作業環境下であっても、該凸部によって十分な滑り止め効果を発揮することができるとともに、滑り止め部材は、すべてゴム材料から形成されており、鋭利な金属製の突起等が存在しないので、作業者がステップや機械本体の足場部分に手やひざ等をついたりしても怪我をするおそれがなく作業の安全性を十分に確保することができる。   According to the present invention, since the anti-slip member installed on the substrate serving as a scaffold is composed of a rubber plate having a large number of convex portions on the surface, it is under a working environment where rain or snow is falling by the convex portions. Even so, the convex portion can exhibit a sufficient anti-slip effect, and the anti-slip member is formed entirely from a rubber material, and there are no sharp metal projections or the like. However, even if a hand or knee is attached to the step or the scaffolding part of the machine body, there is no risk of injury and work safety can be sufficiently ensured.

さらに、滑り止め部材６は、ステップに形成された段差を埋めるようにステップの表面に取り付けられているので、滑り止め部材６とステップ上面との間の段差を小さくすることができ、作業者がステップ上で作業あるいは歩行する際、段差による違和感を軽減することができ、作業環境を向上することができる。   Further, since the anti-slip member 6 is attached to the surface of the step so as to fill the step formed in the step, the step between the anti-slip member 6 and the upper surface of the step can be reduced. When working or walking on a step, a sense of incongruity due to a step can be reduced, and the working environment can be improved.

以下、本発明の建設機械の滑り止め構造の実施の形態を、図１、２に基づいて説明する。図1は滑り止め部材を取り付ける前のステップ構造を示す横断面図であり、図２は、図１に示すステップ構造に滑り止め部材を取り付けた状態を示す。   Hereinafter, an embodiment of a non-slip structure for a construction machine according to the present invention will be described with reference to FIGS. FIG. 1 is a cross-sectional view showing a step structure before the anti-slip member is attached, and FIG. 2 shows a state where the anti-slip member is attached to the step structure shown in FIG.

図１、２において、建設機械の滑り止め構造は、建設機械の機体に取り付けられたステップ支持部材１からほぼ水平に延在し、作業者の足場となるステップを構成する基板２と、基板２に形成された段差５と、この段差５を埋めるように取り付けられた滑り止め部材６を有している。   1 and 2, the anti-slip structure of the construction machine extends substantially horizontally from the step support member 1 attached to the machine body of the construction machine, and includes a board 2 that constitutes a step that serves as a scaffold for the worker, and a board 2. And a non-slip member 6 attached so as to fill the step 5.

ステップ支持部材１は、ステップを構成する基板２を支持できるものであればどのようなものであってもよい。例えば、油圧ショベル等の建設機械のカウンタウエイト等の機体自体や、建設機械に取り付けた枠体あるいは支柱等がある。   The step support member 1 may be any member as long as it can support the substrate 2 constituting the step. For example, there are a machine body such as a counterweight of a construction machine such as a hydraulic excavator, a frame body or a column attached to the construction machine.

基板２は、鋼板あるいは鉄板から形成された略矩形の下板３と、下板３に接合され下板３からほぼ水平方向に延在する鋼板あるいは鉄板から形成された略矩形の上板４とから構成されている。上板４は、上板４の一端側を下板３の他端側３ｂ（図１において右端側）の上面に重ね幅Ｌ３をもって重ね合わせ接合することによって下板３に接合されており、この重ね合わせ接合によって、基板２のステップ支持部材１側には、下板３の上面に上板４の厚さＨ１に相当する高さの段差５が形成される。なお、下板３の幅Ｌ１は、後述する滑り止め部材６によって埋められる段差５の幅Ｌ４と前記重ね幅Ｌ３とから規定され、上板４の幅Ｌ２は、必要とするステップの全体幅から適宜決定される。なお、以下、図１および２において左右方向をステップの幅方向といい、紙面に直交する方向をステップの長手方向という。   The substrate 2 includes a substantially rectangular lower plate 3 formed of a steel plate or an iron plate, and a substantially rectangular upper plate 4 formed of a steel plate or an iron plate joined to the lower plate 3 and extending from the lower plate 3 in a substantially horizontal direction. It is composed of The upper plate 4 is joined to the lower plate 3 by overlapping and joining one end side of the upper plate 4 to the upper surface of the other end side 3b (the right end side in FIG. 1) of the lower plate 3 with an overlap width L3. A step 5 having a height corresponding to the thickness H1 of the upper plate 4 is formed on the upper surface of the lower plate 3 on the step support member 1 side of the substrate 2 by the overlap bonding. The width L1 of the lower plate 3 is defined by the width L4 of the step 5 filled with the anti-slip member 6 described later and the overlapping width L3, and the width L2 of the upper plate 4 is determined from the overall width of the required steps. It is determined appropriately. In the following, the left-right direction in FIGS. 1 and 2 is referred to as the step width direction, and the direction orthogonal to the paper surface is referred to as the step longitudinal direction.

下板３の一端側３ａ（図１において左端側）は、基板２がステップ支持部材１に対してほぼ水平方向に延在するように、適宜の手段によってステップ支持部材１に取り付けられている。ステップ支持部材１の上下方向に対する下板３の取付位置は、図１のようなステップ支持部材１の場合、後述する滑り止め部材６の取り付けを考慮して、ステップ支持部材１の上端から上板４の厚さＨ１以上下方の位置とすることが好ましい。   One end side 3 a (left end side in FIG. 1) of the lower plate 3 is attached to the step support member 1 by appropriate means so that the substrate 2 extends in a substantially horizontal direction with respect to the step support member 1. In the case of the step support member 1 as shown in FIG. 1, the attachment position of the lower plate 3 with respect to the vertical direction of the step support member 1 is determined from the upper end of the step support member 1 in consideration of the attachment of a non-slip member 6 described later. It is preferable to set it to a position below the thickness H1 of 4 or more.

下板３と上板４を重ね合わせ接合することによって上板３の上面に形成された段差５には、この段差５を埋めるように略矩形の滑り止め部材６が取り付けられる。滑り止め部材６は、ゴムシートからなるゴムプレート本体６ａと、ゴムプレート本体６ａの少なくとも幅方向の両端に設けた縁部６ａ１と、該縁部６ａ１の内側においてプレート本体６ａの表面に形成した多数の凸部６ｂとから構成されている。   A substantially rectangular anti-slip member 6 is attached to a step 5 formed on the upper surface of the upper plate 3 by overlapping and joining the lower plate 3 and the upper plate 4 so as to fill the step 5. The anti-slip member 6 includes a rubber plate main body 6a made of a rubber sheet, edge portions 6a1 provided at least at both ends in the width direction of the rubber plate main body 6a, and a large number formed on the surface of the plate main body 6a inside the edge portion 6a1. The convex portion 6b.

ゴムプレート本体６ａの周囲に形成した縁部６ａ１は、凸部６ｂと略等しい高さとされ、縁部６ａ１の上面は、ゴムプレート本体６ａの周囲上面から内方に向けて傾斜して立ち上がる形状とされている。多数の凸部６ｂは、段差５を滑り止め部材で埋めたとき、上板４の上面より上方に突出するようにされている。   The edge portion 6a1 formed around the rubber plate body 6a has a height substantially equal to the convex portion 6b, and the upper surface of the edge portion 6a1 rises inwardly from the peripheral upper surface of the rubber plate body 6a. Has been. A large number of convex portions 6 b are configured to protrude upward from the upper surface of the upper plate 4 when the step 5 is filled with a non-slip member.

滑り止め部材６を構成するゴムプレート本体６ａは、種々のゴム材料から形成することができるが、耐酸性、耐アルカリ性、工作性に優れた硬質ゴムから形成するのが好ましい。また、ゴムプレート本体６ａの板厚は、適宜の厚さとすることができるが、通常、基板２を構成する下板３および上板４の板厚は、１．６mm〜２mm程度であるので、それより若干厚い程度とするのが好ましい。また、ゴムプレート本体６ａの周囲に形成した縁部６ａ１は、ゴムプレート本体６ａと同一材料によってシート本体６ａと一体に形成されている。   The rubber plate body 6a constituting the anti-slip member 6 can be formed from various rubber materials, but is preferably formed from a hard rubber excellent in acid resistance, alkali resistance and workability. Further, the plate thickness of the rubber plate body 6a can be set to an appropriate thickness. Usually, the plate thickness of the lower plate 3 and the upper plate 4 constituting the substrate 2 is about 1.6 mm to 2 mm. It is preferable that the thickness be slightly thicker. Further, the edge 6a1 formed around the rubber plate body 6a is formed integrally with the sheet body 6a from the same material as the rubber plate body 6a.

滑り止め部材６を構成する多数の凸部６ｂは、ゴムプレート本体６ａの表面から略垂直方向に立ち上がる柱状、例えば円柱状や多角柱状等に形成され、ゴムプレート本体６ａと同一材料によってゴムプレート本体６ａと一体に形成されている。該凸部６ｂの高さや径等の大きさ及び隣り合う凸部６ｂ間の間隔は、十分な滑り止め効果を有するように適宜決定されるが、凸部６ｂの高さは、３mm〜４mm程度とするのが好ましい。   A large number of convex portions 6b constituting the non-slip member 6 are formed in a columnar shape that rises in a substantially vertical direction from the surface of the rubber plate body 6a, for example, a columnar shape or a polygonal column shape, and the rubber plate body is made of the same material as the rubber plate body 6a. 6a is formed integrally. The height and diameter of the convex portion 6b and the interval between the adjacent convex portions 6b are appropriately determined so as to have a sufficient anti-slip effect, but the height of the convex portion 6b is about 3 mm to 4 mm. Is preferable.

このように構成された滑り止め部材６は、段差５を埋めるように接着剤（図示せず）等によって下板３の上面に取り付けられる。また、接着剤に換えて、ボルトナットやネジ等の適宜の締結手段（図示せず）によって下板３の上面に取り付けるようにしてもよい。   The anti-slip member 6 configured in this manner is attached to the upper surface of the lower plate 3 with an adhesive (not shown) or the like so as to fill the step 5. Further, instead of the adhesive, it may be attached to the upper surface of the lower plate 3 by appropriate fastening means (not shown) such as bolts and nuts.

この実施の形態の建設機械の滑り止め構造によれば、滑り止め部材６を周囲に縁部６ａ１を形成したゴムシートからなるゴムプレート本体６ａと、ゴムプレート本体６ａと一体に形成した多数の凸部６ｂとから構成したので、雨や雪が降っている作業環境下であっても、十分な滑り止め効果を奏することができる。また、滑り止め部材２，３は、すべてゴム材料から形成されており、鋭利な金属製の突起が存在しないので、作業者がステップの足場部分に手やひざ等をついたりしても怪我をするおそれがなく作業の安全性が確保でき、また、クッション性にも優れているので、作業者は足場上で快適に作業をすることができる。   According to the anti-slip structure of the construction machine of this embodiment, the rubber plate body 6a made of a rubber sheet around which the edge 6a1 is formed around the anti-slip member 6, and a number of protrusions formed integrally with the rubber plate body 6a. Since it is comprised from the part 6b, even if it is under the work environment where it rains or snows, there can exist a sufficient anti-slip effect. The anti-slip members 2 and 3 are all made of a rubber material, and there are no sharp metal protrusions. Therefore, even if an operator puts a hand, knee or the like on the scaffolding of the step, injury is caused. The safety of the work can be ensured and the cushioning property is excellent, so that the worker can work comfortably on the scaffold.

また、ゴムシートの材料として、耐酸性、耐アルカリ性、工作性に優れた硬質ゴムを採用することによって、過酷な作業環境下に適した耐久性及び信頼性に優れた滑り止め部材を得ることができる。また、ゴム材料は、鋼板や鉄板に比べ安価であり、しかも工作性に優れているので、滑り止め構造の製造コストを低減することができる。   In addition, by adopting hard rubber with excellent acid resistance, alkali resistance and workability as the material of the rubber sheet, it is possible to obtain a non-slip member with excellent durability and reliability suitable for harsh working environments. it can. In addition, the rubber material is cheaper than steel plates and iron plates and has excellent workability, so that the manufacturing cost of the anti-slip structure can be reduced.

さらに、滑り止め部材６は、ステップ上で建設機械の作業者が作業あるいは歩行する際に、滑ることのないような必要十分な幅とし、基板２を構成する下板３と上板４とを重ね合わせて接合したときに基板２の端部に形成される段差５を埋めるように取り付けたので、上板４の上面より突出する滑り止め部材６の部分はほぼ縁部６ａ１と凸部６ｂとなり、滑り止め部材６と上板４との間の段差を小さくすることができ、作業者がステップ上で作業あるいは歩行する際、段差による違和感を軽減することができる。また、滑り止め部材６を構成するゴムプレート本体６ａの周囲に傾斜して立ち上がる縁部６ａ１を形成することによって、前記違和感をさらに軽減することができる。   Further, the anti-slip member 6 has a necessary and sufficient width so as not to slip when an operator of the construction machine works or walks on the step, and the lower plate 3 and the upper plate 4 constituting the substrate 2 are formed. Since it is attached so as to fill the step 5 formed at the end portion of the substrate 2 when they are overlapped and joined, the portions of the anti-slip member 6 protruding from the upper surface of the upper plate 4 are substantially edge portions 6a1 and convex portions 6b. The step between the anti-slip member 6 and the upper plate 4 can be reduced, and when the operator works or walks on the step, the uncomfortable feeling due to the step can be reduced. Further, the discomfort can be further reduced by forming the edge portion 6a1 that is inclined and rises around the rubber plate body 6a constituting the anti-slip member 6.

以上、本発明の実施の形態について説明したが、本発明は、前述した実施の形態に限定されず種々の設計変更が可能であり、それらはいずれも本発明に含まれる。   Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various design changes can be made, and any of them is included in the present invention.

例えば、ステップを構成する基板は、基板の両側にステップ支持部材を設け、このステップ支持部材によって両端を支持する構成とすることができる。   For example, the substrate constituting the step may be configured such that a step support member is provided on both sides of the substrate and both ends are supported by the step support member.

また、ステップに形成される段差は、必ずしもステップの一端側に形成する必要はなく、ステップの中央等適宜の位置に形成することができる。ステップに形成される段差は、一枚の基板を折り曲げ加工することによって形成してもよいし、複数枚の板を適宜重ね合わせ接合することによって形成することもできる。要は、滑り止め部材によって埋められる段差がステップに形成されていればよい。なお、ステップおよび滑り止め部材の図１、図２における平面視の形状は、略矩形に限らず適宜の形状とすることができる。   Further, the step formed in the step is not necessarily formed on one end side of the step, and can be formed at an appropriate position such as the center of the step. The step formed in the step may be formed by bending a single substrate or may be formed by appropriately stacking and joining a plurality of plates. In short, it is sufficient that the step filled with the anti-slip member is formed in the step. Note that the shape of the step and the anti-slip member in plan view in FIGS. 1 and 2 is not limited to a substantially rectangular shape, but may be an appropriate shape.

ゴムプレート本体の周囲に形成される縁部は、ゴムプレート本体の幅方向の両端に加え、長手方向の一端側あるいは両端側にも設けてもよい。ステップの洗浄を考慮すれば、幅方向の両端に設けるか、あるいは、幅方向の両端と長手方向の一端にそれぞれ設けるのが好ましい。なお、縁部を設けない構造としてもよい。   The edges formed around the rubber plate body may be provided on one end side or both end sides in the longitudinal direction in addition to both ends in the width direction of the rubber plate body. In consideration of the cleaning of the step, it is preferable to provide them at both ends in the width direction or at both ends in the width direction and one end in the longitudinal direction. Note that a structure without an edge may be employed.

滑り止め部材に設けられる凸部は、円柱状や多角柱状等の柱状や半球状に限らず、円錐台状、多角錐台状、砲弾状等任意の形状とすることができる。   The convex portion provided on the anti-slip member is not limited to a columnar shape such as a columnar shape or a polygonal column shape, or a hemispherical shape, but may be an arbitrary shape such as a truncated cone shape, a polygonal frustum shape, or a bullet shape.
