Description

本発明は、リフトプレート部上に配置され車両ロッカー部を支持する支持ブロックと、この支持ブロックを備えた車両リフト装置に関する。   The present invention relates to a support block that is disposed on a lift plate portion and supports a vehicle rocker portion, and a vehicle lift device including the support block.

従来、車両リフト装置は、リフトプレート部を昇降機構で支持して上下動することで、リフトプレート部上に乗り入れた車両を上下動する。この車両リフト装置を用いて車両をリフトさせて車両の下回りの点検や整備を行うことができる。   2. Description of the Related Art Conventionally, a vehicle lift device moves a vehicle that has entered a lift plate portion up and down by supporting the lift plate portion with an elevating mechanism and moving up and down. By using this vehicle lift device, the vehicle can be lifted for inspection and maintenance of the underside of the vehicle.

図３は従来の車両リフト装置６０を模式的に示す図であり、図４は図３におけるリフトプレート部６２の下側から見たときの模式図である。図３に示すように、昇降機構の支柱６１の上端にはリフトプレート部６２が取り付けられ、昇降機構がリフトプレート部６２を上下動する。昇降機構の詳細は図示していないが、車両５０の左右のロッカー部５１に対向する箇所にそれぞれ支持ブロック６３が配置される。図４に示すように、支持ブロック６３は各リフトプレート部６２の前部と後部にそれぞれ載置される。このような車両リフト装置６０によれば、リフトプレート部６２の上昇に伴い支持ブロック６３が直接車両ロッカー部５１を下側から支持し、下周りに突起物５２がある車両をリフトする。   FIG. 3 is a diagram schematically illustrating a conventional vehicle lift device 60, and FIG. 4 is a schematic diagram when viewed from the lower side of the lift plate portion 62 in FIG. As shown in FIG. 3, a lift plate portion 62 is attached to the upper end of the support 61 of the lifting mechanism, and the lifting mechanism moves the lift plate portion 62 up and down. Although details of the elevating mechanism are not shown, support blocks 63 are arranged at locations facing the left and right rocker portions 51 of the vehicle 50, respectively. As shown in FIG. 4, the support block 63 is placed on the front part and the rear part of each lift plate part 62. According to such a vehicle lift device 60, the support block 63 directly supports the vehicle rocker portion 51 from the lower side as the lift plate portion 62 is lifted, and lifts the vehicle having the protrusion 52 around the lower portion.

図５は従来の各種の支持ブロックを示し、（Ａ）は第１タイプの支持ブロック７０の概略斜視図、（Ｂ）はＣ−Ｃ線に沿う断面図、（Ｃ）は第２タイプの支持ブロック８０の概略斜視図、（Ｄ）はＤ−Ｄ線に沿う断面図、（Ｅ）は第３タイプの支持ブロック９０の概略図、（Ｆ）はＥ−Ｅ線に沿う断面図である。図５（Ａ）及び（Ｂ）に示す支持ブロック７０は、ゴムスポンジ材７１に木材７２を埋設して形成されている。図５（Ｃ）及び（Ｄ）に示す支持ブロック８０は、ゴムのみで形成され、リフトプレート部側に断面矩形状の穴８１を有している。図５（Ｅ）及び（Ｆ）に示す支持ブロック９０は、上記の第１及び第２タイプと異なり、発泡ウレタン製で車両ロッカー部の前後方向に沿って全体に当接し、車両ロッカー部５１の下端部が溝部９１に入り込む。   5A and 5B show various conventional support blocks. FIG. 5A is a schematic perspective view of a first type support block 70, FIG. 5B is a sectional view taken along the line CC, and FIG. 5C is a second type support block. The schematic perspective view of the block 80, (D) is sectional drawing which follows the DD line, (E) is the schematic diagram of the 3rd type support block 90, (F) is sectional drawing which follows the EE line. The support block 70 shown in FIGS. 5A and 5B is formed by embedding a wood 72 in a rubber sponge material 71. The support block 80 shown in FIGS. 5C and 5D is made of rubber only and has a hole 81 having a rectangular cross section on the lift plate portion side. Unlike the first and second types, the support block 90 shown in FIGS. 5 (E) and 5 (F) is made of urethane foam and contacts the entire vehicle rocker portion in the front-rear direction. The lower end enters the groove 91.

上記第１タイプの支持ブロック７０は比較的軽量であるものの、外周部のスポンジ材７１に切れが生じ、内部の木材７２が割れ易いため耐久性がない。第２タイプの支持ブロック８０は型成形するだけで作製できるものの、支持ブロック８０は車両ロッカー部に下側から当接して車両を下支えするため沈み込みが多く生じ、ゴムに切れが生じる。第３タイプの支持ブロック９０は軽量で破損が少ないものの、第１及び第２タイプの支持ブロック７０,８０と比べて長いため、リフトプレート部に配置したり逆に取り外したりする作業に手間を要するばかりでなく、その作業が行われる際支持ブロック９０が車両ボディーに当たらないようにする必要がある。   Although the first type support block 70 is comparatively light, the sponge material 71 at the outer peripheral portion is cut and the internal wood 72 is easily broken, so that it is not durable. Although the second type support block 80 can be produced simply by molding, the support block 80 comes into contact with the vehicle rocker portion from the lower side to support the vehicle, so that a lot of sinking occurs and the rubber is cut. Although the third type support block 90 is light and less damaging, it is longer than the first and second type support blocks 70 and 80. Therefore, it takes time and effort to dispose the third type support block 90 on the lift plate and to remove it. In addition, it is necessary to prevent the support block 90 from hitting the vehicle body when the work is performed.

本発明は上記課題に鑑み、車両ロッカー部を支持しても沈み込みが少なく耐久性のある支持ブロックと、車両を安定して上下動する車両リフト装置と、を提供することを目的とする。   In view of the above problems, an object of the present invention is to provide a durable support block that does not sink even when a vehicle rocker portion is supported, and a vehicle lift device that moves the vehicle stably up and down.

上記目的を達成するため、本発明は、車両リフト装置のリフトプレート部上に配置される支持ブロックであって、リサイクルゴムチップ材をバインダーで加圧成形して成ることを特徴とする。特に、リフトプレート部と対峙する下面に複数の穴が設けられていることが好ましい。   In order to achieve the above object, the present invention is a support block disposed on a lift plate portion of a vehicle lift device, wherein the recycled rubber chip material is pressure-molded with a binder. In particular, it is preferable that a plurality of holes are provided on the lower surface facing the lift plate portion.

上記目的を達成するため、本発明の車両リフト装置は、リフトプレート部と、リフトプレート部を昇降する昇降機構と、リフトプレート部上に配置される支持ブロックと、を備え、支持ブロックがリサイクルゴムチップ材をバインダーで加圧成形して成ることを特徴とする。   In order to achieve the above object, a vehicle lift apparatus according to the present invention includes a lift plate portion, a lifting mechanism that lifts and lowers the lift plate portion, and a support block disposed on the lift plate portion, and the support block is a recycled rubber chip. The material is characterized by being formed by pressure molding with a binder.

本発明の支持ブロックでは、成形素材にヒジキ状のゴムチップ材を使用しているので剛性がある。よって、支持ブロックが車両ロッカー部に強く当たってもゴムの切れや割れが少なく復元力に優れ、キズがつき難い。車両ロッカー部を支持する際沈み込みが少なく、車両を安定して支持することができる。成形素材としてリサイクル材を用いるので、製造コストの低廉化を図ることができる。特に、下面に穴を設けることで軽量化、材料費のコストの削減、成形後の空冷効率を高めることができる。   The support block of the present invention is rigid because it uses a hijiki-shaped rubber chip material as a molding material. Therefore, even if the support block strongly hits the vehicle rocker part, there is little rubber breakage or cracking, and the restoring force is excellent, and it is difficult to be damaged. When the vehicle rocker portion is supported, there is little sinking and the vehicle can be supported stably. Since the recycled material is used as the molding material, the manufacturing cost can be reduced. In particular, by providing a hole in the lower surface, it is possible to reduce the weight, reduce the material cost, and increase the air cooling efficiency after molding.

本発明の車両リフト装置では、リフトプレート部の所定の箇所に本発明の支持ブロックを配置した後昇降機構がリフトプレート部を上昇しても、支持ブロックが車両ロッカー部の重量で沈み込まないで、車両の水平を保ったまま上昇させることができる。   In the vehicle lift device of the present invention, the support block does not sink due to the weight of the vehicle rocker portion even if the lifting mechanism lifts the lift plate portion after the support block of the present invention is disposed at a predetermined position of the lift plate portion. The vehicle can be raised while keeping the level.

以下、図面を参照しながら本発明を実施するための最良の形態について説明する。
図１は、本発明の実施形態に係る車両リフト装置１の概略を示す図である。
本実施形態の車両リフト装置１には、リフトプレート部２が昇降機構３上に配設されている。昇降機構３はリフトプレート部２を支持し、油圧制御で上下動することでリフトプレート部２を上下動する。特に、図示した車両リフト装置１では、リフトプレート部２及び昇降機構３が車幅方向に一対装備されている。 The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram schematically illustrating a vehicle lift device 1 according to an embodiment of the present invention.
In the vehicle lift device 1 of the present embodiment, a lift plate portion 2 is disposed on an elevating mechanism 3. The elevating mechanism 3 supports the lift plate portion 2 and moves the lift plate portion 2 up and down by moving up and down by hydraulic control. In particular, in the illustrated vehicle lift device 1, a pair of lift plate portion 2 and lifting mechanism 3 are provided in the vehicle width direction.

リフトプレート部２は、昇降機構３の上端に取り付けられるリフトプレート本体２１と、リフトプレート本体２１にスライド及び／又は旋回可能に取り付けられている一対のプレート２２，２２と、で構成されている。一対のプレート２２，２２は、リフトプレート本体２１に対し車両の前後方向側に設けられる。前後方向に長い車両をリフティングする場合には、リフトプレート本体２１に対してプレート２２，２２を前後方向に延ばす。車幅の広い車両をリフティングする場合には、プレート２２の端部２２ａをそれぞれ外方向に旋回する。車幅の短い車両を昇降させる場合には、図１に示すように、プレート２２の端部２２ａをそれぞれ内方向に旋回する。ここで、各プレート２２は、リフトプレート本体２１に搭載する車両の前後方向に沿ってスライドのみ可能であっても、旋回軸に対し旋回のみ可能であっても、スライド及び旋回の双方が可能であってもよい。プレート２２には、人手で旋回及び／又はスライド可能にするために取手部２２ｂや、車両下部を直接支持する支持具を挿入するための開口部２２ｃが設けられている。   The lift plate portion 2 includes a lift plate main body 21 attached to the upper end of the lifting mechanism 3 and a pair of plates 22 and 22 attached to the lift plate main body 21 so as to be slidable and / or pivotable. The pair of plates 22, 22 are provided on the vehicle longitudinal direction side with respect to the lift plate body 21. When lifting a vehicle that is long in the front-rear direction, the plates 22, 22 are extended in the front-rear direction with respect to the lift plate body 21. When lifting a vehicle having a wide vehicle width, the end 22a of the plate 22 is turned outward. When a vehicle with a short vehicle width is raised and lowered, as shown in FIG. 1, the end portions 22a of the plate 22 are respectively turned inward. Here, each plate 22 can be slid only along the front-rear direction of the vehicle mounted on the lift plate main body 21, or can only slide and turn even if it can only turn with respect to the turning axis. There may be. The plate 22 is provided with a handle portion 22b for enabling manual turning and / or sliding, and an opening portion 22c for inserting a support member that directly supports the lower portion of the vehicle.

図２は、リフトプレート部２上に配置される支持ブロック３０を示し、（Ａ）は平面図、（Ｂ）は正面図、（Ｃ）は側面図である。支持ブロック３０は断面が等脚台形状であり、リフトプレート部２と対峙する下面３１が上面３２より大きい。上面３２には縦横に交わる溝３３ａ，３３ｂが形成されている。支持ブロック３０の下面３１には複数の穴３４が形成されている。穴３４は、図示する例では略円錐形状であるが、別に略円筒形状であってもその他の形状であってもよい。この穴３４は支持ブロック３０の素材量を減らすためだけではなく、後で説明するように、支持ブロック３０を成形する際の空冷効率を高めるためでもある。図示する例では、支持ブロック３０の上面３２の幅Ｗ１が８５ｍｍ、下面３１の幅Ｗ２が１００ｍｍ、長さＬが１３０ｍｍ、高さＨが８０ｍｍであるので、穴３４の配列は、図示の例では、支持ブロック３０の寸法が長手方向である縦方向に３個、横方向に２個である。穴３４の数は、図示例に限らず、支持ブロック３０の大きさに応じて縦方向、横方向にそれぞれ決めることができる。   2A and 2B show the support block 30 arranged on the lift plate portion 2, wherein FIG. 2A is a plan view, FIG. 2B is a front view, and FIG. 2C is a side view. The support block 30 has an isosceles trapezoidal cross section, and the lower surface 31 facing the lift plate portion 2 is larger than the upper surface 32. On the upper surface 32, grooves 33a and 33b intersecting vertically and horizontally are formed. A plurality of holes 34 are formed in the lower surface 31 of the support block 30. The hole 34 has a substantially conical shape in the illustrated example, but may have a substantially cylindrical shape or another shape. This hole 34 is not only for reducing the amount of material of the support block 30, but also for improving the air cooling efficiency when the support block 30 is molded, as will be described later. In the illustrated example, the width W1 of the upper surface 32 of the support block 30 is 85 mm, the width W2 of the lower surface 31 is 100 mm, the length L is 130 mm, and the height H is 80 mm. The dimensions of the support block 30 are three in the longitudinal direction, which is the longitudinal direction, and two in the lateral direction. The number of holes 34 is not limited to the illustrated example, and can be determined in the vertical direction and the horizontal direction according to the size of the support block 30.

次に、支持ブロック３０の素材について説明する。
本発明の支持ブロック３０は、リサイクルゴムチップ材を接着剤であるバインダーで加圧成形して成る。ここで、リサイクルゴムチップ材には、耐チップ性のものを用いる。例えば、自動車の古タイヤを削ったり、再生タイヤ製造時のタイヤトレッド部を特殊装置で削って得られたものを用いる。これで、支持ブロック３０が部分的に粉砕されることがなく剛性を備えることになる。ゴムチップ材には、例えばヒジキ状のゴムチップ材、即ち海藻のヒジキに類似した形状を有するチップで、長さ８ｍｍ〜２０ｍｍ、太さ約１ｍｍ前後のものを用いる。バインダーには例えばウレタン系のものを用いる。 Next, the material of the support block 30 will be described.
The support block 30 of the present invention is formed by pressure-molding a recycled rubber chip material with a binder as an adhesive. Here, a chip-resistant material is used as the recycled rubber chip material. For example, an old tire of an automobile or a tire obtained by scraping a tire tread portion at the time of manufacturing a recycled tire with a special device is used. Thus, the support block 30 is provided with rigidity without being partially crushed. As the rubber chip material, for example, a hijiki-shaped rubber chip material, that is, a chip having a shape similar to that of seaweed hijiki and having a length of about 8 mm to 20 mm and a thickness of about 1 mm is used. For example, a urethane-based binder is used.

支持ブロック３０の製法について説明する。
支持ブロック３０は、所定の型に例えばヒジキ状のゴムチップ材とバインダーとを混ぜて入れて蓋で加圧することで、ゴムチップ材がバインダーで接着し、型成形することができる。加圧の際加熱するとバインダーでゴムチップ材が効率よく接着することができ、良好に接着成形することが可能となる。
その他別の製法としては、先ず、リサイクルゴムチップ材を計量し、ミキサーに投入して攪拌する。これとは別に、ウレタンプレポリマーを計量して攪拌し、上記ミキサーに投入して攪拌する。得られた混合物を百数十℃に予め加熱したモールド内に流し込み、百数十℃で所定時間プレスで加圧硬化させる。その後モールド内を冷やして成形物である支持ブロック３０を取り出す。加圧硬化後空冷する際、支持ブロック３０に設けた複数の穴３４により冷却効率が向上する。 The manufacturing method of the support block 30 is demonstrated.
The support block 30 can be molded by adhering the rubber chip material with the binder by mixing and mixing, for example, a hijiki-shaped rubber chip material and a binder in a predetermined mold and pressing the lid with a lid. When heated at the time of pressurization, the rubber chip material can be efficiently bonded with the binder, and it becomes possible to perform good adhesive molding.
As another manufacturing method, first, the recycled rubber chip material is weighed, put into a mixer, and stirred. Separately, the urethane prepolymer is weighed and stirred, and then charged into the mixer and stirred. The obtained mixture is poured into a mold pre-heated to hundreds of degrees Celsius, and is pressure-cured with a press at hundreds of degrees Celsius for a predetermined time. Thereafter, the inside of the mold is cooled and the support block 30 which is a molded product is taken out. When air cooling is performed after pressure curing, the cooling efficiency is improved by the plurality of holes 34 provided in the support block 30.

本実施形態による車両リフトについて説明する。
車両をリフトプレート部２上に搭載させた後、リフトプレート部２の各前後部に支持ブロック３０を配置し、昇降機構３でリフトプレート部２を上昇させる。すると、支持ブロック３０の上面３２が車両ロッカー部に当接し車両をリフトする。このとき、支持ブロック３０の上面３２が車両ロッカー部に強く当たるものの、支持ブロック３０は耐チップ性を有するリサイクルゴムチップ材とバインダーとを溶融して成形したので適度の弾力性を有すると共に、剛性が高く、上面３２に切りや割れが生じ難い。よって、支持ブロック３０の耐久性が高くなり、交換回数も少なくてすむ。また、上面３２は支持ブロック３０が有する剛性のおかげで上面３２の中心部が沈み込まないで車両を水平に保ったままで支持する。 A vehicle lift according to the present embodiment will be described.
After the vehicle is mounted on the lift plate portion 2, the support blocks 30 are arranged on the front and rear portions of the lift plate portion 2, and the lift plate portion 2 is raised by the lifting mechanism 3. Then, the upper surface 32 of the support block 30 comes into contact with the vehicle rocker and lifts the vehicle. At this time, although the upper surface 32 of the support block 30 strongly hits the vehicle rocker portion, the support block 30 is molded by melting a recycled rubber chip material having a chip resistance and a binder, so that it has moderate elasticity and rigidity. It is high and the upper surface 32 is less likely to be cut or cracked. Therefore, the durability of the support block 30 is increased and the number of replacements can be reduced. Further, the upper surface 32 supports the vehicle while keeping the center level without sinking the central portion of the upper surface 32 due to the rigidity of the support block 30.

以上、本発明の実施形態を説明したように、支持ブロック３０がヒジキ状のリサイクルゴムチップ材をバインダーで成形して成るので剛性を有し、車両ロッカー部に強く当たっても沈み込みがなく、ゴムの切れ及び割れが少なく、しかも弾性の復元力によりキズがつき難い。よって車両リフト装置１のリフトプレート部２に支持ブロック３０を載置してリフトプレート部２を上昇することで車両ロッカー部を安定して支持することができる。支持ブロック３０の素材はリサイクル材であるので、環境にもやさしい。   As described above, as described in the embodiment of the present invention, the support block 30 is formed by molding a hijiki-shaped recycled rubber chip material with a binder, so that it has rigidity and does not sink even if it hits the vehicle rocker part strongly. There are few cuts and cracks, and it is hard to be scratched by the elastic restoring force. Therefore, the vehicle rocker portion can be stably supported by placing the support block 30 on the lift plate portion 2 of the vehicle lift device 1 and raising the lift plate portion 2. Since the material of the support block 30 is a recycled material, it is environmentally friendly.

本発明の実施形態では、リフトプレート部２が、リフトプレート本体２１に一対のプレート２２をスライド及び／又は旋回可能に取り付けられて構成されている場合を説明しているが、単に昇降機構の上端に各種のリフトプレート部が取り付けられている場合であってもよい。   In the embodiment of the present invention, a case is described in which the lift plate portion 2 is configured by attaching a pair of plates 22 to the lift plate body 21 so as to be slidable and / or pivotable. It may be a case where various lift plate portions are attached.
