Description

[Detailed description of the invention] Regarding machines.

11lJ people were standing on the Asno Nord paved road.[-1] In order to carry out the work, we first started by using 1r coal. It is already known that there is a heart change in which the entire surface of the lli-equipped road surface is cut.

For this purpose, only a few asphalt pavement cutting machines have been developed in recent years, and the number of lino-cutting machines with known dimensions is limited to this JPi.
Ji. l/! It is installed in the Spell (/j) and is based on the combination with one or more water bags.
In the state where l+ is stopped J1, the hammer performs a downward movement toward the road surface, then enters a predetermined cutting depth above the road surface, then stops the 31V movement, and periodically moves upward to a position above the road surface. It is designed to be operated by・
- When the crab is in its resting position, the worker operates the boat to move forward to the next cutting work location, where the above cutting work cycle is repeated.

Currently on the market, the ``2-type furnace cutting μy 1 machine'' has the disadvantage that it is hardly functionally complete. II
However, the degree of automation is insufficient, and there is a need to make a decision as to whether or not there is no work for prostitutes, and how this should be done.
However, there is the disadvantage of relying on the ability of the contractor for the 1' work.In addition, the work of cutting these rocks is i, + i' (only for the line IJJ cutting work). To perform a road surface cut that defines an excavation area of a predetermined width, l l;
There is also the inconvenience that the linear LJJ break must be repeated in parallel to the JJ break.

The purpose of the invention is to move from one work place to the next.
The asphalt I/paving system is capable of completely automatically carrying out the entire work cycle, including advancing the vehicle to the r-. ．．
The goal is to realize JJ Daniso.

Another object of the present invention is to. Rather than giving the field + month 1j1, the desired movement (parallel 2, I
The amount of asphalt pavement cutting that can be carried out in the first month of Zψ is determined by the actual J'JI.

Execution of descending movement, 11/1° above the road surface
A task consisting of a movement and de-energization of the vehicle to return it to its resting state, and a forward movement of the vehicle over an adjustable predetermined distance to reach the next work point. It is characterized in that it is configured to automatically carry out repeated expansion of the cycle.

Therefore, in other words, the cutting machine according to the invention is capable of automatically carrying out a series of Q-cuts 1'+ work cycles and automatically moving from one cutting operation to the next similar operation.
It's like being able to do it. For this reason, the only obligation placed on the operator is to maintain the correct driving direction of the self-propelled vehicle, which is clearly a rather simple task, and yet there is no real possibility of error. There are no such cases.

A saw cutter according to an embodiment of the present invention includes at least two machines instead of one in the prior art, one at a predetermined interval that can be adjusted by +/-1. ! II, and the other is installed on the other side! 111
- It is considered a sign. Therefore, according to this cutting machine, it is possible to simultaneously form two parallel cutting lines that define the desired excavation width instead of one cutting line at a time.

Therefore, the operation of the cutting machine is streamlined, the trenching work speed is accelerated, wasted time is further reduced, and the asphalt pavement cutting machine and the excavator following it can be used simultaneously. It becomes a scolding. , history, these aspects of the present invention
According to the new implementation 1+, the two hammers are in contact with their direct contact 1q'J! Sensing means and implementation means are employed which operate so that they are put into operation after K is reached. According to this configuration, even if the road surface is f(;
Even if the two hammers are slanted, high or low, or have depressions, the two hammers will be at the same depth HQ1. (
The cutting of i+-1rrJ, optionally with regulating oil, is carried out to give 1'lJ capability. The effect/advantage C brought about by this [is undoubtedly obvious.

, 2 and 2 are operatively connected via a 6-mark unit on the medium heat side of the upper air-hydraulic subtype, but are not connected to the hydraulically operated components of the same unit or more preferably. The operating components are shown in the hydraulic or L-bend wiring diagram of FIG. 6. From the same figure, each operation (shallow separate) with water pressure or d oil J-,)-7 IJ tank 13 and hammer 9! 1f is connected to the upper air or hydraulic pressure 6141 taste distributors 21 and 22, which are still connected to one of the connecting bonnets 26 and 23 and the discharge part 2.
It will be understood that it is connected to 4. A valve system including an adjustable throttle 25 and a check (or one-way) valve 26 is installed between the hydraulic cylinder 16 and the distributor 21 . As shown, each of the two distributors 21 and 22 can be operated in three operating positions or postures: 111J, a resiliently held center or neutral J position, a right-switched or "feed-out" position, and a left-switched position. Alternatively, it can be switched to the "spitting" position. Switching the distributor 22 to the delivery position or posture is as follows:
The slidable inner lug 18 of the sensing means or sensor 16 engages the microswitch 19 and the signals 28 , 28 emitted by the microswitch 19 , 19 associated with the hydraulic hammer 9 are simultaneously present at the logic gate 27 . It is supposed to be done at some point. The distributor 22 is switched to the discharge position by using microswitches 20, 20 combined with the sensor 16, instead of the above.
occurs only subject to the intervention of a signal 29 emitted by . Regarding the distributor 21, please refer to the microphone "
To the signal from the outside issued by the J switch 65":
is switched to the dispensing position and still receives the signal 29 described above.
It can be switched to the sending position by

For both distributors 21 and 22, switching to the neutral position occurs under the control of 43 and 44 generated by the microswitch 56 when the top end of the slider 7 in the rest position engages the microswitch 56. It has become.

The wiring diagram of FIG. 6 still shows that a piston 62 is mounted on which a cam 64 is fixedly attached to its rod or frame 66, and the cam 64 operates in cooperation with two microswitches 65 and 66, the height of which is adjustable. Also shown is a hydraulic or hydraulic 7-cylinder 61 having a hydraulic pressure. Under the control of the tissue distributor 7, which takes place in conjunction with the action of two check valves 50 and 51, also two
Utilizing the functions of the check valves 68 and 69 and the maximum pressure valve 40, the piston 32 causes the water pressure or hydraulic motor 41 that acts on the drive wheels 46 of the vehicle 1 through the transmission system 42 to operate as required in an appropriate manner. It is designed to supply pressure. Also shown in FIG. 6, the distributor 67 has three operating positions: a center or "neutral" position, a right-switched or a "neutral"position;
The "feed-out" position and the left-hand switch can be switched to the "discharge" position. The distributor 67 is switched to the delivery position when the signal 44 issued by the microswitch 56 is present when the slider 7 is held at the rest position, and the distributor 67 is switched to the discharge position when the cam 64 is activated. This occurs only when there is a signal 60 emitted by the microswitch 65 when engagement begins. Furthermore, switching to the neutral position is adapted to occur in response to a signal 46 emitted by microswitch 66 when cam 34 is engaged. Furthermore, another distributor 47 is provided, which is equipped with a check valve 52 and can be switched from the discharge position to the delivery position by operation of the pump 48, as shown in FIG. As a result of this operation, the hydraulic motor 41 and therefore the driving wheels 43 of the vehicle 1 are operated independently of other operations.

The hydraulic connection configuration and hydraulic or electric control configuration shown in FIG. Alternatively, it is possible to only hold the vehicle in a predetermined running direction. The complete sequence of operations will be described below, with the vehicle at rest and the hydraulic engine in one raised position with respect to the road surface (indicated by reference numeral 49 in Figures 1 and 7). It is assumed that the starting point is at rest, and that the divine distributor of the central open side 1 device is in the neutral position of FIG.

In the state at the start of work as described above, the distributor 21 is moved to its discharge position. Then,
The hydraulic fluid (or other hydraulic fluid) in the chamber below the relative pistons 45 and 65 in the hydraulic or hydraulic cylinders 13 , 13 begins to flow toward the discharge section at a flow rate regulated by the IX sections 25 , 25 . As a result, the sliders 7゜7 of the actuating equipment groups 2, 2 begin to descend due to gravity along the vertical guides 8, 8, causing the hydraulic power units 9, 9 to move toward the ground, and responding accordingly. The slidable inner lug 18.degree. 18 of the sensor 16, which was in firm contact with the ground, is partially retracted within the respective outer lug 17.

Such a downward movement continues until the sensors 16 , 16 assume a position in which their inner parts 117 , 17 engage the respective microswitches 19 , 19 , but this position 9°9 cutting blade 12,
12 to correspond to the contact with the work surface or ground, which remains constant regardless of whether the circuit surface or ground is completely horizontal or more or less sloped as shown in Figure 7. It is something. In fact, even if the ground is sloped, there are undulations or undulations on the ground, the necessary compensation is made by sliding the sliders 8, 8 back into the frames 4, 4 at different depths, Regarding the ground
It is clear that the final position of the sensors 9, 9 and therefore the final position of the telescopic sensor 16.16 can also be constant. Therefore, no matter what the shape of the ground, the cutting machines can operate with the same specifications, and the two
・The cutting blades of the machine are now in constant contact with the ground, and in this state, the micro switch 1 mentioned above.
9 and 19, the next cutting operation is started.

When the two sheets of glue shear force 12 , 12 reach a state of contact with the road surface or ground 49 , the telescopic sensor 16 ,
16 realizes engagement of microswitches 19 and 19,
Then, each of the same microswitches emits a signal 28,
When logic gate 27 detects the simultaneous presence of these signals 28, 28, 7=-i, tributor 22 is switched to the delivery position. At this time, the slider 7.7 is still subject to downward movement due to gravity, but at this time the hammer 9,
9 operations are carried out, which perform road cutting operations on both sides of the vehicle.

When a predetermined depth is reached, the cutting operation is completed, and at this time, the 11411 portions 118, 118 of the fl+l movable sensors 16, 16 are engaged with the upper microswitches 20, 20. The mounting position of the suitably adjustable microswitches 20, 20 thus defines the cutting depth that the cutting machine achieves during each working cycle.

A signal 29 is emitted by the engagement of the microswitches 20 and 20 described above, and the operating position or posture of the distributors 22 and 21 is switched by the signal, and the distributors 22 and 21 are discharged.
At lf'i, switches 21 and 21 are again switched to the sending position. Then, the distributors 21, 21 and the check valves 26,
The pumps 23 , 23 are connected to the hydraulic cylinder 13 via 26 .
, 13, the hydraulic fluid is sent below the pistons 45, 65 of the sliders 7, 7, and therefore the cylinders 9, 9 and the outer portions 17, 17 of the sensors 16, 16 to perform an upward movement.

This upward movement causes the slider 7.7 to return to its rest position and the microswitches 53, 53 to switch the distributor 21.21 and the distributor 22,
22 to the neutral position, the process ends. At the same time, the same signal 44 changes the tissue distributor 7 to the sending position, and the screw I/N 62 of the hydraulic cylinder 31 is driven downward, causing the water pressure or hydraulic motor 4
This hydraulic oil drives the Φ wheels 46 through the transmission system 42, and the vehicle 1 is moved forward from the ground or road surface area where cutting work has been completed to the next work area. This forward movement ends when the cam 64 attached to the frame 63 of the piston 32 engages the microphone tip 65, which emits a signal 60, which causes the distributor 67 to reach the discharge position. It controls the switching to IFC and the corresponding upward movement of the piston 32.In this way, the forward movement of the vehicle is regulated by the position of the microswitch 65, and its adjustment or Changes can easily be made.

To replace the distributor 37 described above: the re-piston 62 is brought to the upper limit of its reciprocating stroke, represented by the microswitch 36, which still emits the signal 46, thereby causing the distribution The Taro 7 is switched to its neutral position, and the above-mentioned signal 30 causes the taste distributor 21 to switch back to the dispensing position, thereby starting the next cutting cycle, after which the vehicle is advanced. Furthermore, this operating cycle force (is repeatedly developed).

As described below, according to the illustrated cutting machine according to the present invention,
fully automatically and, as already mentioned, parallel to each other at predetermined intervals that can be adjusted or changed regardless of the slope of the ground or road surface and/or the presence or absence of undulations or depressions in its shape. A pair of 9) breaks can be formed at a predetermined depth below the road surface, which can also be adjusted or changed, and over a length, which can also be adjusted or changed.

Therefore, according to the invention, it is possible to perform completely reliable cutting operations as appropriate for a variety of purposes, and also to simultaneously form a pair of parallel cutting lines. Asphal l-.

Work efficiency can be doubled compared to pavement cutting machines. In addition to these, an uninvented cutting (according to some sources, it is possible to perform two parallel J-cuts that define the excavation width at the same time), an excavator is placed immediately behind this cutting machine, and both road surface cutting and excavation are carried out. It becomes i, iJ ability to complete all tasks in the shortest possible time1
