Description

【0001】
【発明の属する技術分野】
本発明はトンネル内でのズリ積出し機(ダンプトラックなど)への積込を補助する自走式ズリ積込装置に関する。
【0002】
【従来技術】
従来の技術として特許公告公報平5−84799号に開示された自走式ズリ積み機が開示されている。
【0003】
【発明が解決しようとする課題】
従来技術の自走式ズリ積み機は図6に示すように、走行手段30の走行方向に直角に設けられた向合うベルトコンベア31、32と囲い部材33からなるズリ積込部34を設け、ここに積み込まれたズリをベルトコンベア31、32によって、ズリ積込部34の中央下に落し、該中央下から立ち上げたズリ搬出用ベルトコンベア部35によってを搬出するというもので、ズリ出し機が来たらベルトコンベア31、32と搬出用ベルトコンベア部35を作動させて、ズリ積込部34のズリを、ズリ出し機に搬送積み込むというものであり、搬出作業の効率化及び無人化を主目的としたものである。
【0004】
この従来技術は、ズリ積込部34がベルトコンベア31、32を走行方向に対して横向きとして、掘削現場の巾寸法をカバーしているので、掘削機械の排出端がズリ積込部34からずれることはなく、すべてのズリを中央の搬出用ベルトコンベア部35の上に集めることができ、また自走式のため、ダンプトラックは一箇所に止まったままで、ズリの集積荷を受けられるるという効果を奏する。
しかし、ズリ積込部34の容量に限りがあるため、ズリが積み込まれて満杯となると、自走移動して、搬出用ベルトコンベア部35を作動させてズリ出し機に搬送積込みをするが、その間のズリ積込部34への積込みは中止せざるを得ないという問題点があった。
また、トンネル内はその幅が狭い上に、ズリ積込部34が掘削現場の巾寸法をカバーしているので、通路の確保等が制限されるため、作業上必要な移動の際に危険性を伴うものであった。
【0005】
本発明は従来技術の持つ以上のような問題点に鑑みてなされたものであって、その目的は、トンネル内でダンプローダ等のズリ掘削積込機が作業を中断することなく、常時、間断なくズリの積込み、積出しを行うことができる、安全な自走式ズリ積込装置を提供するにある。
【0006】
【課題を解決するための手段】
上記目的を達成するために本発明は、自走手段と、この自走手段の上部に、ズリの積込側を低く搬出側が高くなるように傾斜をつけて設けられた、ズリを搬送する長尺のベルトコンベアと、このベルトコンベアの周側面にめぐらして設けた囲い部材とからなり、当該囲い部材を積込み側にいくに従って深くし、かつ当該囲い部材の上方を積込み側にいくに従って扇形に広くし、前記ベルトコンベア及び前記囲い部材の水平方向に対する傾斜角度を変えることができるようにすることにより、当該囲い部材へのズリの投入量を増減可能としたことを特徴としている。
【0007】
また、ベルトコンベア及び囲い部材を、自走手段上で横に振ることができるようにしてなることを特徴とする
【0008】
また、トンネル内でサイドダンプローダ等を横付けして、前記囲い部材の側部側からからズリを積み込めるように、ベルトコンベア及び囲い部材を幅狭に形成したことを特徴とする。
【0009】
【発明の実施の形態】
図1は本発明の実施の形態1を示す平面図、図2は同じ実施の形態1を示す側面図、図3は同じ実施の形態1を示す正面図、図4は同じ実施の形態1のトンネル内での使用状態例を示す側面図、図5は同じ実施の形態1のトンネル内での使用状態例を平面図である。
【0010】
自走式ズリ積込装置1は、無限軌道からなる自走手段2の上部に設けた一本のベルトコンベア3と、ベルトコンベア3に積まれたズリが溢れこぼれないようにするための囲い部材6とからなっている。
囲い部材6は、積込側4に行くにしたがって深くなっている。さらに、積込側4にいくに従って上の方が扇型に広がっている。このため、多量のズリを積み込むことができ、ホッパーの役割をも果たしている。
ベルトコンベア3と囲い部材6とにより、ズリ積込搬送部7が形成されている。
ズリ積込搬送部7はコントロール手段8により、その傾斜角度(搬出側5を高く積込側4を低くする)を水平から19度の範囲内で、横向き角度を15度の範囲内で、自在に変えることができるように形成されている。
スクリュージャッキ9は、傾斜角度に対応して調節し、ズリ積込搬送部7をその下端において、地面を基礎にして支持するためのものである。
装置全体の横幅は1.4メートル(1メートル〜2メートル位がよい)、ズリ積込搬送部7の横幅1.25メートル、全長(ズリ積込搬送部7の長さ)7.61メートル(6メートル〜10メートル位がよい)となっている。
【0011】
囲い部材6が、積込み側で深く、扇形に広くしてホッパーの役割を果たしているため、ベルトコンベア3作動中でも、サイドダンプローダー18によるズリの積込み作業は中止することなく、常時続けることが可能である。。
【0012】
ベルトコンベア3及び囲い部材6は、コントロール手段8によって、自走手段2上で角度15度の範囲内で横に振ることができる。これによって、積出し用のダンプトラックを2台並べておいて、1台がズリで満杯になると、そのままトンネルの外に出て行き、排出して戻ってくるまでの間は、ベルトコンベア3及び囲い部材6を横に振って、もう1台のダンプトラックへズリの積み込み作業を行うことができる。このように、2台のトラックを交互に使用して、ズリの積込み、積出し作業を連続して行うことが可能である。
【0013】
ベルトコンベア3及び囲い部材6の幅を狭くして、トンネル内でサイドダンプローダ18を横付けして、囲い部材6の側部側からズリを積み込めるようにしている。これによって、ダンプローダ18を前進、後進させるだけで積み込み作業を行うことができるので、作業能率を大きく向上させると共に、ショベル等を回転させないで積込み作業ができるので、回りのものにショベル等を衝突させる危険を軽減し、安全性を向上させた。
【0014】
ベルトコンベア3及び囲い部材6の傾斜を変えることができるので、傾斜を少なくしてベルトコンベア3を寝かせて、囲い部材6へのズリの投入量をふやすことができる。また、天井の低い、狭くて小さいトンネル内への出入りや、トンネル内での作業をスムースに行うことができる。
【0015】
次に、本発明の作用について述べる。
サイドダンプローダ18と、自走式ズリ積込装置1と、ダンプトラック17をそれぞれの定位置につける。ベルトコンベア3を作動させ、サイドダンプローダ18を自走式ズリ積込装置1の横につけ、ズリを側部側から囲い部材6に積み込んで行く。自走式ズリ積込装置1に積み込まれたズリは、ベルトコンベア3で搬送搬出され、ダンプトラック17に受け渡される。サイドダンプローダ18は、前進してズリをショベルに積み込み、バックしてきて自走式ズリ積込装置1の横に止め、再び自走式ズリ積込装置1にズリをあけていく。この操作を何回か繰り返して、ベルトコンベア3の作動により、ダンプトラック17に所定のズリが積み込まれていく。
1台のダンプトラック17が満杯になると、排出するため、トンネルの外に出て行く。ベルトコンベア3及び囲い部材6を、コントロール手段8によって、自走手段上で横に振って、並べて置かれているもう1台のダンプトラック17へのズリの積み込み作業を行う。このように、2台のトラックを交互に使用して、ズリの積込み、積出し作業を連続して行う。
また、サイドダンプローダ18は、装置1の側部に横付けして、囲い部材6の側部側からズリを入れるという、前進と、後進をさせるだけの操作で作業が進行していく。
また、作業工程の変更時や作業終了時には、自走式ズリ積込装置1のベルトコンベア3を寝かせて、自走手段によって自由に移動走行させる。
【0016】
【発明の効果】
本発明の自走式ズリ積込装置は、以下のような効果を奏する。
積込側により多くのズリを積み込むことができるように、囲い部材を積込側に行くに従って上方を扇型に広げ、また深くしているので、ベルトコンベアの搬送能力以上のズリを受け積み込むことが可能となり、サイドダンプローダによるズリの積込を、常時継続して行うことができ、搬出能力を大幅に向上させ、積み出し時間を短縮することができる。
また、装置全体の幅を狭くしてサイドダンプローダを自走式ズリ積込装置の積込側に横付けし、ズリを側部側から積み込むことを可能にしたので、サイドダンプローダを前進、後進させる操作だけですみ、作業効率を大きく向上させると共に、回りのものにショベル等を衝突させる危険を軽減するので、安全性を大幅に向上させる。装置全体の幅の狭くしたことにより、狭いトンネル内における通路の確保が容易になり、人員の移動等の際に、危険性が大幅に減少する。
【0017】
また、ベルトコンベア及び囲い部材を自走手段上で横に振ることができるので、2台のダンプトラックを交互に使用して、ズリの積出し作業を継続して行うことができ、トラックの排出時にベルトコンベアの作動を中止していた従来例に比べて、作業効率を大きく向上させる。
さらにベルトコンベアの傾斜を自由に変えることができるので、ズリの積み込み量を増やすことができル。また、自走式ズリ積込装置のトンネル内での移動をスムースに行うことができ、狭いトンネル内での使用を可能としている。

The belt conveyors 31 and 32 and the carry-out belt conveyor unit 35 are operated, and the gap in the gap loading section 34 is transported and loaded into the gap take-out machine. It is intended.
[0004]
In this prior art, since the slack loading part 34 makes the belt conveyors 31 and 32 sideways with respect to the traveling direction and covers the width of the excavation site, the discharge end of the excavating machine is displaced from the slack loading part 34. It is possible to collect all the gaps on the central conveyor belt 35 for unloading, and because of the self-propelled type, the dump truck can remain in one place and receive the piled load. There is an effect.
However, since the capacity of the slip loading section 34 is limited, when the slip is loaded and it becomes full, it moves by itself, operates the carry-out belt conveyor section 35, and loads and loads it on the slipping machine. There was a problem that the loading to the slip loading unit 34 during that time had to be stopped.
Moreover, since the width of the tunnel is narrow and the gap loading part 34 covers the width of the excavation site, the passage of the passage is restricted, which may be dangerous when moving as necessary for work. It was accompanied by.
[0005]
The present invention has been made in view of the above-described problems of the prior art, and the purpose of the present invention is to ensure that the excavator and loader such as a dump loader does not interrupt the operation in the tunnel, and without interruption. The object of the present invention is to provide a safe self-propelled slip loading device capable of loading and unloading slip.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a self-propelled means and an upper portion of the self-propelled means, which is provided with a slant so that the loading side of the sled is low and the carry-out side is high. A belt conveyor and a surrounding member provided around the peripheral side surface of the belt conveyor. The enclosure member becomes deeper as it goes to the loading side, and the area above the enclosure member becomes wider in a fan shape as it goes to the loading side. In addition, by making it possible to change the inclination angle of the belt conveyor and the enclosing member with respect to the horizontal direction, the amount of slippage into the enclosing member can be increased or decreased .
[0007]
Further, the belt conveyor and the enclosure member, characterized by comprising can thus receive the shake on self-propelled unit.
[0008]
Further, the belt conveyor and the enclosure member are formed to be narrow so that a side dump loader or the like can be laid sideways in the tunnel and a gap can be loaded from the side of the enclosure member.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
1 is a plan view showing the first embodiment of the present invention, FIG. 2 is a side view showing the same first embodiment, FIG. 3 is a front view showing the same first embodiment, and FIG. FIG. 5 is a side view showing an example of the usage state in the tunnel, and FIG. 5 is a plan view of the usage state in the tunnel of the same embodiment 1.
[0010]
The self-propelled slip loading device 1 includes a single belt conveyor 3 provided on an upper part of a self-propelled means 2 having an endless track, and an enclosure member for preventing the slip accumulated on the belt conveyor 3 from overflowing. It consists of six.
The surrounding member 6 becomes deeper as it goes to the loading side 4. Furthermore, as it goes to the loading side 4, the upper side spreads out in a fan shape. For this reason, a large amount of misalignment can be loaded, and it also serves as a hopper.
The belt conveyor 3 and the surrounding member 6 form a slip loading and conveying section 7.
Sliding loading and unloading section 7 can be freely controlled by control means 8 so that its inclination angle (unloading side 5 is high and loading side 4 is low) is within the range of 19 degrees from the horizontal, and the lateral angle is within the range of 15 degrees. It is formed so that it can be changed.
The screw jack 9 is adjusted to correspond to the inclination angle, and supports the gap loading and conveying portion 7 at the lower end thereof based on the ground.
The overall width of the device is 1.4 meters (preferably about 1 meter to 2 meters), the lateral width of the sludge loading and conveying section 7 is 1.25 meters, and the total length (the length of the slack loading and conveying section 7) is 7.61 meters ( 6 to 10 meters are good).
[0011]
The enclosure member 6 is deep on the loading side and widened in a fan shape to serve as a hopper. Therefore, even when the belt conveyor 3 is in operation, the loading operation of the side dump loader 18 can be continued without interruption. is there. .
[0012]
The belt conveyor 3 and the surrounding member 6 can be swung sideways within a range of 15 degrees on the self-running means 2 by the control means 8. As a result, when two dump trucks for loading are arranged side by side and one of them is full, the belt conveyor 3 and the enclosing member go out of the tunnel as they are, and until they are discharged and returned. 6 can be swung side by side and loaded into another dump truck. In this way, it is possible to carry out the loading and unloading operations continuously by alternately using two tracks.
[0013]
The width of the belt conveyor 3 and the enclosing member 6 is narrowed, and the side dump loader 18 is placed sideways in the tunnel so that a gap can be loaded from the side of the enclosing member 6. As a result, the loading operation can be performed simply by moving the dump loader 18 forward and backward, so that the work efficiency can be greatly improved, and the loading operation can be performed without rotating the shovel or the like. Reduced danger and improved safety.
[0014]
Since the inclination of the belt conveyor 3 and the surrounding member 6 can be changed, the amount of slippage into the surrounding member 6 can be reduced by reducing the inclination and allowing the belt conveyor 3 to lie down. In addition, it is possible to smoothly go in and out of a narrow and small tunnel with a low ceiling and work in the tunnel.
[0015]
Next, the operation of the present invention will be described.
The side dump loader 18, the self-propelled slip loading device 1, and the dump truck 17 are attached to the respective fixed positions. The belt conveyor 3 is operated, the side dump loader 18 is placed on the side of the self-propelled slip loading device 1, and the slip is loaded on the surrounding member 6 from the side portion side. The slip loaded on the self-propelled slip loading device 1 is conveyed and carried out by the belt conveyor 3 and delivered to the dump truck 17. The side dump loader 18 moves forward to load the slip on the shovel, backs up and stops next to the self-propelled slip loading device 1, and opens the slip on the self-propelled slip loading device 1 again. This operation is repeated several times, and a predetermined gap is loaded on the dump truck 17 by the operation of the belt conveyor 3.
When one dump truck 17 is full, it goes out of the tunnel for discharge. The belt conveyor 3 and the enclosing member 6 are swung sideways on the self-propelled means by the control means 8 to carry out the loading operation of the other dump truck 17 placed side by side. As described above, the loading and unloading operations are continuously performed by alternately using two tracks.
Further, the side dump loader 18 is laid on the side portion of the apparatus 1 and the operation proceeds only by the forward and backward operations of inserting the gap from the side portion side of the enclosing member 6.
Further, when the work process is changed or when the work is finished, the belt conveyor 3 of the self-propelled slip loading device 1 is laid down and freely moved by the self-propelled means.
[0016]
【The invention's effect】
The self-propelled slip loading device of the present invention has the following effects.
The upper part of the enclosure is fanned out and deepened as it goes to the loading side so that more gaps can be loaded on the loading side. This makes it possible to continuously load the gap by the side dump loader, greatly improving the carrying capacity and shortening the loading time.
In addition, since the width of the entire device is reduced and the side dump loader is placed on the loading side of the self-propelled slip loading device, it is possible to load the slip from the side. The operation efficiency is greatly improved, and the danger of colliding an excavator or the like with surrounding objects is greatly reduced, thus greatly improving safety. By reducing the width of the entire apparatus, it becomes easy to secure a passage in a narrow tunnel, and the danger is greatly reduced when personnel move.
[0017]
In addition, since the belt conveyor and the enclosure member can be swung sideways on the self-propelled means, the dumping work can be continued by using two dump trucks alternately, and when the truck is discharged Compared to the conventional example in which the operation of the belt conveyor is stopped, the working efficiency is greatly improved.
In addition, the inclination of the belt conveyor can be changed freely, so the amount of loading can be increased. In addition, the self-propelled slip loading device can be smoothly moved in the tunnel, and can be used in a narrow tunnel.
