BACKGROUND OF THE INVENTION
The present invention relates to a cutting device for a slope pavement that can cut a cutting machine while collecting and transporting the cut pavement waste material on a slope pavement such as a dam constructed using civil engineering technology. It is.
[0002]
[Prior art]
In general, asphalt impermeable methods, such as paving an asphalt impermeable layer on slopes, are popular as methods for impermeable walls such as high dams, reservoirs, and reservoirs. Such an asphalt impermeable method is not only high in water impermeability, but also has a semi-permanent durability integrated with a main body structure such as a dam, so that its reliability is extremely high.
[0003]
However, even though it is highly water-resistant and durable, repair may be necessary due to aging of the sunk body or asphalt water-blocking layer (hereinafter referred to as “asphalt layer”). In addition to removing the asphalt layer where repair is needed to the pavement depth required for repair, it was necessary to pave and repair a new asphalt layer at the removal site.
[0004]
As a means for removing this asphalt layer, conventionally, a method has been used in which an operator operates a pneumatic breaker or the like to remove the asphalt pavement manually, and in this case, the generated asphalt pavement waste material (Hereinafter referred to as pavement waste) was manually collected in a bucket and transported to the top of the slope by a crane, and transported to a predetermined disposal site by a pavement waste transport vehicle such as a dump truck.
[0005]
However, this type of slope paving work by human power is a dangerous work on slopes with poor workability, and is essentially a work accompanied by awkwardness in which dust or the like is generated. In addition, in the case of asphalt pavement in which the existing asphalt layer is composed of multiple layers, it is difficult to accurately lift only a part of the surface layer, etc., but on the other hand, the collection work of pavement waste manually requires a large number of steps. In addition, large construction costs are required.
[0006]
As a method and a machine device for efficiently cutting and removing a road surface of asphalt pavement, for example, there are those described in JP-A-9-21107 and JP-A-9-21108.
[0007]
This method consists of a self-propelled cutting machine that is equipped with a belt conveyor that transports pavement waste material to a transport vehicle such as a dump truck for repairing asphalt road pavement and a self-propelled dump truck. First, cutting is performed by a cutting machine, and then the cut pavement waste is collected to the belt conveyor outlet, and the pavement waste collected at the outlet is collected by the belt conveyor. It is transported sequentially to the transport vehicle.
[0008]
However, if this method is applied to the slope pavement as it is, the cutting machine and the transport vehicle will be self-propelled on the slope, respectively, so that the self-propelled cutting machine and the self-propelled transport vehicle will slip or fall over on the slope. In addition, there is an inconvenience that there is a high risk of cutting, and in addition, when the slope is steep, in the device configuration, there is a risk that both the cutting machine and the transport vehicle slide down the slope, so that the cutting operation is impossible.
[0009]
[Problems to be solved by the invention]
Therefore, the problem to be solved by the present invention is that the cutting machine does not fall on the slope pavement, and it is possible to collect cutting and pavement waste materials by mechanical force even in a particularly steep slope pavement. By this, it is providing the cutting device of the slope pavement which can implement | achieve the improvement of the safety | security of the said work, and cost reduction.
[0010]
That is, the slope pavement cutting device according to the present invention cuts the slope pavement and collects and transports the cut pavement waste material by the pavement waste material collecting and conveying means, while moving along the top of the slope. together and a moving traction means counterweight towing the cutting machine at the string-shaped member is attached, the Himocho of adjusting the length of the string-shaped member to one of said cutter or said moving traction means a cutting apparatus slope paving and a regulating means, the cutting machine, the movement and the Himocho of adjusting means of the cord-like member long follow-up to the upper inclined surface paved in regulating the moving traction means It has follow-up movement means that move freely vertically and horizontally,
The pavement waste material collecting and conveying means includes a pavement waste material hopper for storing the pavement waste material collected by cutting,
The conveyance amount adjustment feeder that quantifies and conveys the pavement waste material stored in this pavement waste material hopper, and conveys the pavement waste material discharged from this conveyance amount adjustment feeder while sucking from the suction port, and the middle part is lifted by the lifting means A suction conveyance hose that is lifted and a decompression device that includes a decompression tank that applies a suction force to the suction conveyance hose by setting the inside to a negative pressure, and the suction port rotates with respect to the conveyance amount adjustment feeder It is connected freely and follows the movement of the cutting machine freely .
[0011]
According to this invention, since the cutting machine can freely travel on the slope pavement in a state where the cutting machine is pulled through the wire from the highly stable moving traction means, there is no risk of the cutter being slid and falling, and is safe. In addition to ensuring the property, it is possible to cut the slope pavement even if the slope portion has a steep slope.
In addition, it is equipped with a transport amount adjustment feeder, and the cut pavement material is sucked and transported with a suction transport hose so that it can be collected quantitatively and stably, and the dust of the pavement material will be scattered around the transport process. Can be prevented.
Further, by lifting the midway portion of the suction conveyance hose with the lifting means, it is possible to avoid a situation in which the cutting operation of the cutting machine is hindered by dragging the suction conveyance hose.
Further, by attaching a counterweight to the moving traction means that moves along the top of the slope, it is possible to prevent the movement traction means from becoming unstable.
Moreover, since the suction conveyance hose is rotatably connected to the conveyance amount adjustment feeder, the suction conveyance hose can freely follow the movement of the cutting machine.

[0027]
Next, in this embodiment, the operation of the slope pavement cutting apparatus when performing a cutting operation will be described with reference to FIGS. 1 to 3. For convenience of explanation, first, the operation of the device configuration of the winch porter 2 and the cutting machine 1 will be described, and then, in addition to these device configurations, the case where the vacuum wheel 14 and the crane 6 are connected will be described. .
[0028]
(A) Operation of winch porter 2 and cutting machine 1 First, the operation when only the winch porter 2 and the cutting machine 1 are connected will be described.
[0029]
Prior to the cutting operation, as shown in FIGS. 1 and 2, counterweights 24 and 25 are attached to the winch porter 2 before and after the vehicle body 22 in the traveling direction. Then, in addition to the weight of the winch porter 2, a load is applied, and the instability of the winch porter 2 due to the towing of the cutting machine 1 can be prevented.
[0030]
In this embodiment, since the counterweights 24 and 25 are detachable as described above, the model (weight) of the cutting machine 1 can be changed by replacing the counterweights 24 and 25 with other weights. Even if it is changed, it is possible to easily cope with it and it is efficient.
[0031]
First, when the winch 4 is operated and rotated in a forward or reverse direction at a substantially constant speed, the length 3 of the wire 3 varies as the wire 3 is wound or sent out ( As a result, the cutting machine 1 travels on the slope S in either the front-rear direction (the direction of arrow C in FIG. 1) while maintaining a substantially constant speed.
[0032]
For example, when the wire 3 is wound and the length L is shortened, the cutting machine 1 is secured at the tip portion of the wire 3, so that the cutting machine 1 counters its own weight while facing the winch porter 2, that is, It is wound up in the direction of the top end of the slope S.
[0033]
On the other hand, when the wire 3 is fed out and the length L is lengthened, the cutting machine 1 is unwound from the winch porter 2 via the wire 3, and the cutting machine 1 is gradually pulled while being pulled by the winch porter 2 with its own weight. The vehicle runs on the slope S in the downward direction.
[0034]
On the other hand, the length L of the wire 3 fed out by operating the winch 4 is increased, and the cutting machine 1 is moved downward on the slope S. Thereafter, the winch porter 2 is caused to travel along the top end T in the left-right direction. Thereafter, the winch 4 is operated to wind the wire 3 and the steering of the cutting machine 1 is operated, whereby the cutting machine 1 travels obliquely on the slope pavement. As a result, the cutting machine 1 You can change the cutting lane.
[0035]
Therefore, according to the slope pavement cutting apparatus according to the present embodiment, the cutting machine 1 can freely travel on the slope pavement while being pulled from the highly stable winch porter 2 via the wire 3. In addition to ensuring the safety of the cutting machine 1 without slipping and falling, the cutting machine 1 enables cutting of the slope pavement even on a particularly steep slope part.
[0036]
(B) Operation of the winch porter 2, the cutting machine 1, the vacuum wheel 14 and the crane 6 Next, the device structure for connecting the winch porter 2 and the cutting machine 1 is used, and in addition to the device structure, the vacuum wheel 14 and the crane. The operation when 6 is further connected will be described.
[0037]
First, by operating either one of the winch porter 2 and the winch 4 or a combination thereof, the cutting machine 1 is moved until it comes to the top end T side of a predetermined cutting lane to be cut.
[0038]
At this time, the vacuum wheel 14 and the crane 6 are moved following the traveling operation of the winch porter 2, the boom 6 a of the crane 6 lifts the suspended portion B of the suction hose 13, and further the vacuum wheel 14 and the cutting machine 1. Since the position of the suction hose 13 can be freely adjusted while being lifted by turning the boom in conjunction with traveling, the situation in which the cutting operation of the cutting machine 1 is hindered by dragging the suction hose 13 is avoided. And a smooth cutting operation of the cutting machine 1 can be realized.
[0039]
Prior to the cutting of the asphalt layer A, the entire unit of the cutting drum 33 is moved up and down by hydraulic operation while rotating the cutting drum 33 at a high speed in the rotation direction (arrow C direction in FIG. 3). The cutting depth is adjusted by adjusting the depth of penetration of the slope S of 33a into the pavement surface. At this time, since the cutting depth can be freely set and only the pavement thickness necessary for the repair can be cut and removed, a rational repair work can be realized.
[0040]
And while starting the operation | movement of the drawer bellcon 34 and the conveyance amount adjustment feeder 12, the operation | movement of the vacuum wheel 14 is also started, the attraction | suction force with respect to the suction hose 13 is provided, and the operation | movement which sucks and conveys the cut pavement waste material at any time Prepare for the transition.
[0041]
Next, when the wire 3 is unwound and the length L is increased, the cutting machine 1 starts to move on the slope S from the top end T side to the bottom end side of the cutting lane.
[0042]
Then, when the cutting drum 33 is rotated at a high speed in the rotation direction C while moving the cutting machine 1, the cutter bit 33 a implanted in the cutting drum 33 is spread over the entire length of the cutting drum 33 in the asphalt layer A. Will be cut sequentially.
[0043]
Then, the asphalt piece cut by the cutting drum 33, that is, the pavement waste material, is placed on the drawer bell-con 25 by the rotational force of the cutting drum 33 and the shape of the frame space 32, and is transported. After being received, it is dropped by a certain amount into the suction port 35 by the transport amount adjusting feeder 12 and immediately sucked into the suction hose 13 together with the surrounding air.
[0044]
At this time, the suction amount can be adjusted by the air damper 36 in accordance with the length of the suction hose 13, that is, the transport distance by suction of the pavement waste material, so that good suction transport is possible.
[0045]
Therefore, according to the slope pavement cutting device according to the present embodiment, while effectively avoiding the diffusion of the pavement waste material cut by the frame space 32, the cut pavement waste material is temporarily stored in the pavement waste material hopper 11, The stored pavement waste material is quantified by the conveyance amount adjusting feeder 12 and the pavement waste material is sucked by a vacuum vehicle 14 having a function as a collection and conveyance means, and the suction hose 13 also has a function as a conveyance vehicle. Since it is transported to the vacuum vehicle 14, it is possible to stably and efficiently collect the cut paving waste material, and to prevent the dust of the paving waste material from being scattered around in the process of cutting and transporting. This eliminates the need to clean and remove the scattered pavement waste material and improve the surrounding working environment.
[0046]
Further, according to the vacuum vehicle 14 according to the present embodiment, when the decompression tank 14a is filled with the pavement waste material, the decompression tank 14a may be transported as it is to a predetermined disposal site. Since it is not necessary to take measures for preventing the scattering of pavement waste, which was necessary in the case of transportation by truck, the pavement waste treatment as a whole can be carried out very easily and efficiently. Moreover, since it is not necessary for the pavement waste material transport vehicle to travel on the slope pavement, safety can be further improved.
[0047]
【The invention's effect】
Since the slope pavement cutting apparatus according to the present invention is configured as described above, it is possible to cut a paved road surface on a steep slope portion that has been impossible in the past.
[0048]
According to this cutting method, it is not necessary to manually remove the entire layer of asphalt pavement at the repair location, and it is possible to cut and remove to the pavement depth that requires repair. Can be realized.
[0049]
Further, according to the slope pavement cutting device of the present invention, on the slope pavement, it is possible to prevent the cutting machine from overturning, the pavement waste material does not scatter to the periphery, and it is easy to collect the cut pavement waste material. By using a waste material hopper and a conveyance amount adjustment feeder, the cut pavement waste material can be conveyed stably and efficiently in a certain amount, which can improve the safety and cost of the work. It is possible to realize a simple slope pavement cutting method.
