Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crawler-type slope traveling machine which travels on a slope by a crawler-type lower traveling body, and particularly to a construction machine for traveling on a gentle slope to perform construction work or a gentle slope. It is effectively applied to a transport machine that travels on slopes and transports construction materials.

[0002]

2. Description of the Related Art In recent years, as a measure against earthquakes and rainfall such as embankment slopes, the ground is rotated and excavated by a drilling / mixing machine such as an earth auger type while the soil and the solidifying material are mixed and stirred to be solidified, and further the central portion thereof is solidified. The slope strengthening method for constructing the anchor body has been developed and implemented.

When such a slope strengthening method is applied to a gently sloping slope, conventionally, in small-scale construction, materials are manually transported, and work such as drilling and mixing is performed by a backhoe type construction machine arranged on a side road. Was going on.
Further, in a relatively large-scale construction, a temporary gantry for construction machinery was erected, and an earth auger type construction machine was placed on this temporary gantry for drilling and mixing work.

Further, as a method for transporting construction materials such as earth and sand, concrete blocks, pipes and sheet piles on a slope, conventionally, a method of manually transporting, a method of transporting by a belt conveyor, and a temporary transport path on a slope are constructed. The method of doing was adopted.

[0005]

However, in the conventional slope strengthening method on a gentle slope, it is difficult for a person to move freely on the slope and earthwork, and the work efficiency is extremely low, And dangerous work,
This will increase the construction period and increase the cost,
If there is no side road in front of the slope, there is a problem that a backhoe type construction machine cannot be installed.

In addition, when a temporary gantry is installed,
Since there is a problem that the construction period is long and the cost is high because the temporary gantry is erected, if there is no side road in front of the slope, the materials for the temporary gantry must be transported manually. It has the same problem as in the case of human power.

Further, the conventional construction material transporting method also has the following problems.

(1) Method by human power Only small materials can be transported, large and heavy materials cannot be handled, it is difficult for a person to move freely on a slope, and transportation efficiency is extremely poor, and It is a dangerous work, and the transport efficiency is poor, so the construction period is long and the cost is high.

(2) Method by Belt Conveyor Although it is possible to convey earth and sand, it is difficult to convey other materials. It is difficult to install a belt conveyor on a slope.

(3) Method of constructing a temporary transportation route If the transportation route is small, such as a manual transportation route, the transportation efficiency is poor.
Since a temporary gantry is constructed, the construction period and cost increase.

An earth auger type crawler type construction machine is run on the slope to directly implement the slope strengthening method,
Alternatively, it is possible to transport materials, but the crawler track of the current crawler type traveling machine only has a grouser (projection) in a direction orthogonal to the traveling direction, and it is not possible to climb or descend a slope. Although it can be done, it cannot run on the slope in the horizontal direction (direction orthogonal to the slope gradient direction), and the stability during work is poor, so that it cannot be carried out.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to allow free and safe traveling on a slope and to secure stability during work. Also, construction work such as strengthening the slope and transport work of construction materials can be performed efficiently even on the slope, and the conventional manual work is reduced as much as possible, and the temporary construction gantry is unnecessary, shortening the construction period and reducing the construction cost (EN) Provided is a crawler-type slope traveling machine capable of achieving the above-mentioned object and further improving the skid-preventing effect on the slope without damaging the slope protection member and the like laid on the slope.

[0013]

A crawler-type slope traveling machine according to the present invention is a crawler-type slope traveling machine equipped with a crawler belt in which shoe elements are connected endlessly, and is particularly used for a slope strengthening method. It is applied to crawler type construction and construction machines such as crawler type drilling / mixing machines and crawler type transport machines equipped with an upper loading platform, and is used for shoe elements made of hard rubber or shoe elements covered with hard rubber. In addition to the claws (normal grocers) in the direction orthogonal to the running direction on the ground contact surface, a shape that extends parallel or inclined to the running direction (a member that is long in the running direction, such as a plate-shaped protrusion) And a protrusion made of hard rubber or a protrusion covered with hard rubber, or a shape having a short width in the traveling direction and a long length in the vertical direction (for example, a columnar portion). ) In and projections or coated protrusions with hard rubber made of hard rubber, namely providing the hard rubber anti-skid Grosser.

The shape of the protrusions extending parallel to or inclined with respect to the traveling direction is a plate-like one long in the traveling direction or a rod-like one long in the traveling direction to prevent the skid of the traveling machine. Any shape can be used as long as it can be obtained,
It is preferable to use a plate material in terms of good penetration into the ground and ease of manufacturing. Further, the respective protrusions may be arranged so as to be continuous in the traveling direction, or may be discontinuous without being continuous, and a gap may be provided between the protrusions. Further, each protrusion may be inclined with respect to the traveling direction.

In the case where a large disturbance on the slope that occurs when the traveling machine changes its direction is disliked, or when a concrete frame (lattice frame) for slope protection is laid on the slope, etc., the width of the slope should be short. It is preferable to use protrusions that are long in the vertical direction. Such protrusions include columnar protrusions such as rod-shaped protrusions, cylindrical (box-shaped) protrusions, deformed plate-shaped protrusions, conical protrusions, and truncated cone protrusions. Independently, or a plurality of them are arranged at intervals in the traveling direction.

In the case of both a plate-shaped protrusion that is long in the running direction and a protrusion that is short in the running direction and long in the up-down direction, the height of the protrusion is the claw that is orthogonal to the running direction of the crawler track. The effect of preventing skidding is greater when the height is larger than that of a normal grouser.

Although it is better to provide these protrusions on the crawler belts on both the mountain side and the valley side, it is effective to provide them only on the crawler belts on the sloped valley side (both sides of the crawler belt or only one side on the valley side). Is.

[0018]

With the above construction, the traveling machine main body is caused to travel in the horizontal direction of the inclined surface and stopped at a predetermined position to perform work such as drilling / mixing and discharge of construction materials.

The shoe element constituting the crawler belt is provided with a plate-shaped or columnar-shaped projection, that is, a skid prevention grouser, in addition to the claw (normal grocer) in the direction orthogonal to the traveling direction, so that skid during traveling can be prevented. Greatly eliminated, safe and stable driving enables efficient slope strengthening and transportation work. In addition, stability is ensured by the skid-proof grouser even with respect to work load, and work such as drilling and mixing can be performed safely.

Since the crawler belt is made of hard rubber, it is possible to travel without breaking the existing concrete method frame or the like on the slope. Further, hard rubber has a larger ground resistance than metal, and can travel on a slope without slipping. Moreover, even if the rainwater guide projecting portion of the concrete method frame is sandwiched by a pair of plate-like projections that are arranged in front and rear in the traveling direction, since it is made of hard rubber, shear failure of the rainwater guide projecting portion can be eliminated.

In addition, if the columnar projections are arranged in a scattered manner, when the slope traveling machine is turned, the sediment on the slope surface will not be disturbed significantly, and the rainwater guide projection portion of the concrete frame will not be disturbed. There is no risk of shearing by pinching.

The height of the skid preventive grouser is greater as the skid preventive effect is higher, and it is preferable that the height is higher than that of the claws orthogonal to the traveling direction of the crawler belt. If the height of the skid prevention grouser is made too high, the turning performance of the main body of the traveling machine deteriorates and the slope is damaged (disturbed), so the upper limit is determined in consideration of this. Further, the skid-preventing grouser on the valley side surface of the crawler belt on the trough side has a great skid-preventing effect.

As shown in FIG. 4, the shoe element 18 is, for example, a curved portion 1 which is curved inward at the tip in the traveling direction.
8a, a unit member in which a plurality of claws (grocers) 19 extending in a direction orthogonal to the traveling direction are provided on the surface, and a bracket 20 provided on the lower surface is provided with a bracket 21 and an endless chain link 22. It is connected by being attached to. The shape and structure of the shoe element 18 are not limited to those illustrated.

In such shoe element 18, according to the present invention, as shown in FIG. 1, wide plate-shaped projections (anti-skid grousers) 23 are provided on both sides of the ground surface of the shoe element 18 along the traveling direction. , The shoe element 18 itself and the protrusion 23 itself are made of hard rubber R
Or the metal shoe element 18 and the metal projection 23 are covered with a hard rubber R having a predetermined thickness.

Further, although not shown, a hard rubber protrusion 23 may be integrally attached to the hard rubber covered shoe element 18, or the hard rubber shoe element 18 may be covered with a hard rubber. The protrusion 23 may be attached integrally. The bracket 20
When the shoe element 18 is made of hard rubber, the shoe element 18 is integrated by embedding the base portion in the hard rubber, and when made of metal, the shoe element 18 is integrally attached to the shoe element 18.

Here, as the hard rubber, those used for tires and the like can be used. Further, the projection 23 has substantially the same length as the effective length of the shoe element 18 so that a continuous plate-shaped stabilizer is formed in the straight line portion. In this case, the plate-like protrusions 23 are continuous with almost no gap, but may be intermittent with a gap.

Height H from the surface of the shoe element 18
Is larger than the height h of the claw 19. Reinforcing ribs 24 may be provided inside the protrusions 23 as needed to improve the strength. When the shoe element 18 and the protrusion 23 are made of metal, the shoe element is usually cut and produced from a long molding material. Therefore, the protrusion 23 is manufactured separately from the shoe element 18, and is welded or bolted. And so on. It is also possible to manufacture it integrally with the shoe element 18.

The positions of the protrusions 23 are not limited to the widthwise side portions of the crawler belt 12, but the shoe elements 18
It is also possible to dispose one or a plurality of them in the middle portion in the width direction. Further, although the plate-like protrusions 23 are arranged parallel to the traveling direction, they may be inclined with respect to the traveling direction.

Further, the projection 23 is not limited to a plate-like or rod-like shape elongated in the traveling direction, but may be a plurality of independent columnar projections 23 'elongated in the vertical direction as shown in FIG. Also in this case, the shoe element 18 is made of hard rubber R, or the shoe element 18 made of metal is coated with the hard rubber R, and the columnar protrusions 23 'are made of hard rubber R, or The shoe element 18 made of rubber is coated with hard rubber R.

The planar arrangement of the columnar projections 23 'includes the same row arrangement, the staggered arrangement, and the random arrangement. The shape is not limited to the cylinder or prism shown in FIG. 2, but may be a cylindrical (box-shaped) projection, a deformed plate-shaped projection, a conical projection, a truncated cone projection, or the like as shown in FIG.

As shown in FIG. 5, the crawler type drilling / mixing machine 1 having the above-described structure is arranged on a gentle slope, and is run in the horizontal direction of the slope to swing the upper swing body 4 at a predetermined position. Then, the front attachment 5 is tilted / rotated / slipped to perform rotary excavation / mixing / stirring of the solidifying material / fixing of the anchor material in any working posture.

When traveling in the horizontal direction, the projections 23 provided on the crawler belt 12 function as plate-shaped stabilizers, and the sliding of the inclined surface in the vertical direction can be greatly reduced.

As a result, stable running and efficient work can be performed, and skidding can be prevented even with respect to the load during work, and work can be performed safely.

Here, when the protrusions 23 are made of metal, and in the case where only the earth and sand are not coated on the slope, the skid prevention effect is large and very effective. However, when a concrete frame (lattice frame) or the like for slope protection is laid on the slope, the concrete frame or the like may be destroyed. On the other hand, according to the present invention, since the crawler belt 12 is made of hard rubber, it is possible to travel without breaking the concrete frame or the like. Further, hard rubber has a larger ground resistance than metal and has the advantage that it can run on a slope without slipping.

If there is no gap between the pair of metal plate-like projections moving forward and backward in the running direction, the pair of plates moving forward and backward in the running direction of the rainwater guide projecting portion of the concrete grid frame. It may be sandwiched between the protrusions and sheared, but if it is made of hard rubber, such sheared fracture can be eliminated.

It should be noted that the pillar-shaped protrusions 2 are arranged in a scattered manner and are independent of each other.
If it is 3 ', when changing the direction of the slope traveling machine 1,
Unlike plate-like projections 23, it is possible to reduce large disturbance of the sand on the slope surface, and there is no possibility of shear failure due to sandwiching the rainwater guide projecting portion with continuous plate-like projections.

The above is an example of application to a drilling / mixing machine for slope reinforcement, but it goes without saying that the present invention can also be applied to a crawler type construction machine or the like that runs on a slope and performs other constructions. Nor. For example, a bucket may be attached to the upper swing body to serve as a backhoe, or a bulldozer earthwork plate, a crane, or the like may be attached.

Further, it goes without saying that the invention can also be applied to a crawler type slope carrier for transporting construction materials. FIG. 6 shows an example of this crawler type slope carrier, which is mainly composed of a horizontal upper loading platform 102 on which construction materials are placed and a crawler type lower traveling body 103.

The upper loading platform 102 is a loading platform having an open upper portion on which a long object such as earth and sand or a concrete block, or a pipe or sheet pile can be placed.
It is mounted so that it can tilt in a direction orthogonal to the traveling direction. That is, the mounting table 120 is provided on the base frame 104 of the lower traveling body 103, and the lower surface of the upper loading platform 102 is attached to the mountain side of the mounting platform 120 via the pin shaft attachment mechanism 121. Between them, a pair of hydraulic cylinders 122 are arranged in the traveling direction.

In this hydraulic cylinder 122, the cylinder base is pinned to the base frame 104, and the tip of the piston rod is pinned to the lower surface of the upper cargo bed 102. The hydraulic unit that operates the hydraulic cylinder 122 is the lower traveling body 103.
It is housed in the lower traveling body 103 together with the driving mechanism of (1) to lower the center of gravity. It is preferable that the hydraulic cylinder 122 can also be housed in the lower traveling body 103 at the lowest stroke position, and that the upper platform 102 is horizontally mounted on the platform 120 on a level ground.

By expanding and contracting the piston rod of the hydraulic cylinder 122, the inclination angle of the upper loading platform 102 can be adjusted so that the upper loading platform 102 can always be kept horizontal with respect to various slopes of the inclined plane during horizontal traveling on the inclined plane. It is possible, and by increasing the tilt angle from this state, the upper loading platform 1
It is possible to incline 02 toward the mountain side and discharge the earth and sand.
In addition, the side plate on the mountain side of the upper loading platform 102 is the opening / closing door 102a.
In addition, it is possible to easily discharge earth and sand.

The center of gravity of the upper carrier 102 in the direction orthogonal to the traveling direction is eccentric to the mountain side of the position of the center of gravity of the lower traveling body 103, and a moment opposite to the overturning moment is generated when the inclined traveling is horizontal. It acts on 103 to reduce the overturning moment. In addition,
An operation box is provided on the lower traveling body 103 so that an operator can drive and operate the platform. Further, a driver's seat may be provided on the lower traveling body 103.

Also in the crawler type slope carrier having the above-mentioned structure, the shoe element 1 made of the hard rubber described above is used.
By providing the hard rubber projections 23 or 23 ′ on 8, the same effect as the crawler type construction machine described above can be obtained. It should be noted that the upper platform 102 can be held horizontally by the hydraulic cylinder 122 and can always be kept horizontal with respect to various slopes, so that earth and sand will not be spilled during traveling, and construction materials can be safely used. Can be transported. Furthermore, by increasing the tilting angle, it is possible to safely and automatically discharge earth and sand to the mountain side. Further, since the center of gravity of the upper loading platform is eccentric to the mountain side, the overturning moment can be reduced, and safer traveling is possible.

A crane may be attached to the above-mentioned slope transporter 101 to load and unload materials such as concrete blocks.
