Here, A is a river, B is an upstream sewer, C is an upstream pit, D is an overpass, E is a downstream pit, and F is a downstream sewer. In addition, H is a manhole cover for closing the opening of the hole, and I, and I is a work step in the hole and ho (which serves as a scaffold for the worker). In the sewer section of the sewer, sludge and sediment accumulate over the years in the manhole and the bottom of the pipe (the tons, chi and li indicate the accumulated sludge and sand). The cross section is reduced and the roughness is increased, resulting in a situation where the flow of sewage is hindered.
In order to drown the earth and sand at the bottom of the manhole, conventionally, 1) Bypass was set up in the sewer near the overpass, and the flow of the sewer in the overpass was cut off (ie, dried up) Top), the method of roughening the earth and sand in the manhole, or 2) the method of dredging the earth and sand in the bottom of the manhole by a diver without stopping the flow of the sewer.
However, depending on the above method 1), the work for blocking the sewer flow near the overpass and providing a bypass is large and time-consuming, and the construction cost becomes enormous. Depending on the method of 2) above, there are various problems in both 1) and 2) such as being inefficient and dangerous because of the manual work of divers.
For this reason, a dredging method using a mechanical force using a grab bucket or the like is conceivable. However, according to the peculiarity of the underpass manhole, there are various problems depending on the general-purpose dredging method.
That is, 1) the overturning human hole has a large depth, 2) the opening is closed by a small-diameter manhole cover (which is opened and closed by human power, so that it can be made as small as possible), and the lower part is expanded in diameter. It has a special feature such as the bottom of a large cross-section, and 3) the bottom of a manhole has a large gravel and a solid sediment layer.
For this reason, depending on the normal scissor method, 1) it is difficult to insert and remove the grab bucket in the narrow opening, and 2) even if it can be inserted through the narrow opening, It is difficult to reach the grab bucket and dredge the soil all over the bottom of the expanded manhole (especially the work step in the manhole is an obstacle), and 3 ) There are technical problems such as it is difficult to excavate dredged sediment layer.

From this point of view, the present applicants previously proposed the following earth and sand machine for human holes in Japanese Patent Application Laid-Open No. 61-246433 (hereinafter referred to as “prior art”).

The mounting part is pinned to the upper end of the upper post. The second-stage hydraulic cylinder is interposed between the intermediate post and the lower post, and the cylinder side mounting part is pinned to the upper end of the intermediate post. The side mounting portion is pin-fixed to the lower end of the lower post, and the lifting hydraulic cylinder is connected to the post support frame on the cylinder side, and the piston rod side is connected to the upper post of the lifting post.

It can be accurately lowered into the hole, and is suitable for soil dredging for an underpass manhole.
In addition, a large pressing force can be applied to the anchor attachment attached to the lower end of the lifting post as appropriate by driving the lifting hydraulic cylinder, so that the earth and sand anchor that is firmly consolidated to the bottom of the overturning manhole can be realized.
Furthermore, the lifting cylinder can be moved up and down by the lifting hydraulic cylinder, so that the attachment and removal work for the dredging attachment or the sediment discharge work to the dump truck can be easily performed, and the lifting post can be moved horizontally. This machine can be stably mounted on a vehicle and can be mounted on a small vehicle.
However, depending on this prior art,
1) The cross section of the lifting post is forced to increase with the depth of the human hole, making it difficult to insert it into the opening of the human hole.
2) The length of the lifting post increases with the depth of the human hole, so the ground height is large and it is difficult to work in a narrow space.
3) It takes time to change the attachment attached to the lifting post.
There are problems such as.
Furthermore, although the prior art uses hydraulic cylinders, the hydraulic power source of these hydraulic cylinders, that is, the hydraulic power unit, is arranged on the vehicle unit on the ground. There is a problem that the distance to the hydraulic cylinder, that is, the hydraulic actuator increases, and the operability deteriorates.
This problem is an inevitable technical problem as the depth of the human hole increases.
From this point of view, the techniques described in JP-A-10-159171 and JP-A-2000-54424 separately proposed by the present applicant have similar problems, and improvement in hydraulic operability is a major development theme. It has become.
Furthermore, in any of the above-mentioned known techniques, the dredging becomes a work in the sludge in the manhole in addition to the great depth, and it is difficult to grasp the position, posture and operating status of the bucket, It is a difficult task requiring skill.

Specifically, the post operation lever button 160 causes the insertion post portion 1 to undulate and turn left and right by operating the lever. That is, the forward “rise” raises the insertion post portion 1, and the rearward “bush” causes the insertion post portion 1 to fall. To the right (in the direction B), the insertion post portion 1 is turned to the right through the swivel 21, and to the left (in the direction B), the insertion post 1 is turned to the left through the turntable 21.
With the lever operation, the arm operation lever button 170 moves the link arm unit 4 up and down and turns left and right. In other words, forward insertion (C direction) raises the insertion post portion 1 by winding the wire 15, and backward movement (D direction) lowers the insertion post portion 1 by rewinding the wire 15. Inclining to the right (in the direction of E) turns the link arm unit 4 to the right, and inclining to the left (in the direction of F) causes the link arm unit 4 to rotate to the left.
The bucket operation lever button 180 raises / lowers the bucket unit 5 and opens / closes it by operating the lever. That is, the forward “swing” (G direction) swings up the link arm 4, and the backward “swing” (h direction) swings down the link arm 4.

If it is in the “automatic” mode, the process proceeds to step S26, “operation” (“start”) is turned on on the “automatic operation” screen, and the process further proceeds to step S27. In step S27, it is determined whether or not the automatic driving condition is satisfied. The automatic operation conditions are the following three conditions: 1) the initial teaching has been set, 2) no emergency stop, and 3) the arm is on the ground. If the automatic operation condition is not satisfied, the process returns to step S26, and after performing an operation that satisfies the automatic operation condition, “operation” is turned ON. If the automatic driving condition is satisfied, the “RUN” button is turned on in step S28, and the process proceeds to step S29.
Referring to FIG. 25, it is determined whether or not the angle of link arm 4 is 0 ° (vertical) in step S29. If it is not 0 °, link arm 4 is swung down (lowered) in step S30 to 0 °. And If the angle of the link arm unit 4 is 0 °, the process proceeds to step S31, and it is determined whether or not the turning angle of the link arm unit 4 is the approach angle β. As described above, the approach angle β is a set angle that is inserted while avoiding an obstacle when inserted into the human hole P, and may be 0 ° or unlimited. If it is the approach angle β, the process proceeds to step S33, and it is determined whether the bucket unit 5 is closed. If the bucket part 5 is not closed, it moves to step S34 and the bucket part 5 is closed. If the bucket part 5 is closed, it will move to step S35.
Referring to FIG. 26, insertion post portion 1 is lowered in step S35, and it is determined in step S36 whether the depth of insertion post portion 1 is the arm movable position. The arm movable position is set so that the bucket 5 is 3 m deeper than the opening O of the human hole P as a guide. If it is not the arm movable position, the process returns to step S34, and the lowering of the insertion post portion 1 is continued. If the depth of the insertion post portion 1 is the arm movable position, the process proceeds to step S37, and it is determined whether or not the arm turning angle is at the scraping position. The calculation of the angle position of the arm turning angle is performed on the basis of the angle obtained by folding α from the origin position, that is, the manhole direction. If it is not a scraping position, it moves to step S38 and the link arm part 4 is turned to a scraping position. If the link arm unit 4 is in the scraping position, the process moves to step S39, and it is determined whether or not the angle of the link arm unit 4 is in the scraping position. If it is not a scraping position, it will move to step S40 and the link arm part 4 will be raised to a scraping position. If the link arm part 4 is a scraping position, it will move to step S41.
Referring to FIG. 27, bucket portion 5 is opened in step S41, then insertion post portion 1 is lowered in step S42, and the process proceeds to step S43. In step S43, it is determined whether or not the tension limit switch (LS) is ON. If it is not ON, the process proceeds to step S44, and it is further determined whether or not the scraping method is “distance measurement”. If the scraping method is not “distance measurement”, the process returns to step S43. If the scraping method is “distance measurement”, the process proceeds to step S45, where it is determined whether the depth is the scraping depth. If the depth is not the scraping depth, the process returns to step S43. The scraping depth is the current depth plus the scraping depth (scraping depth = current depth + scraping depth). If the depth is the scraping depth, the process proceeds to step S46 along with the determination that step S43 is ON. Thereby, scraping by the bucket part 5 is performed.
Referring to FIG. 28, the lowering of insertion post portion 1 is stopped in step S46, and then insertion post portion 1 is raised in step S47. Furthermore, it moves to step S48 and it is determined whether the depth is the arm movable position. If it is not the arm movable position, the process returns to step S47. If it is the arm movable position, the raising of the insertion post portion 1 is stopped in step S49.
Referring to FIG. 29, it is then determined in step S50 whether or not the angle of link arm portion 4 is 0 °. If it is not 0 °, the flow proceeds to step S51, and link arm portion 4 is lowered. If it is 0 °, the process proceeds to step S52, where it is determined whether or not the turning angle of the link arm part 4 is the approach angle β. If not, the process proceeds to step S53 and the link arm part 4 is turned to the approach angle β. Return to S52. If the link arm portion 4 has the approach angle β, the insertion post portion 1 is raised in step S54, and then it is determined in step S55 whether the ascending end limit switch LS is ON. If the rising end limit switch LS is not ON, the process returns to step S54 and the insertion post portion 1 is further lifted. If the rising end limit switch LS is ON, the process proceeds to step S56. Thereby, the bucket part 5 goes out to the ground part.
Referring to FIG. 30, it is determined in step S56 whether or not the turning angle of the link arm unit 4 is “intermediate position”. If the turning angle of the link arm unit 4 is not “intermediate position”, the process proceeds to step S57. Part 4 is turned. If the turning angle of the link arm unit 4 is “intermediate position”, the process proceeds to step S58 to determine whether or not the angle of the link arm unit 4 is “intermediate position”, and the angle of the link arm unit 4 must be “intermediate position”. In step S59, the link arm unit 4 is raised. If the angle of the link arm unit 4 is “intermediate position”, the process proceeds to step S60, where it is determined whether or not the turning angle of the link arm unit 4 is “payout position”. If not, the process proceeds to step S61, and the link arm unit 4 is turned. If the turning angle of the link arm unit 4 is the “dispensing position”, the process proceeds to step S62.
Referring to FIG. 31, it is determined in step S62 whether or not the angle of link arm portion 4 is the “payout position”. Is made. If the angle of the link arm part 4 is the “payout position”, the process proceeds to step S64 and the bucket part 5 is opened. As a result, dredged soil is discharged to the dump truck. In step S65, the bucket unit 5 is kept open for 3 seconds. In step S66, the bucket unit 5 is closed, and the process proceeds to step S67.
Referring to FIG. 32, in step S67, it is determined whether or not the angle of link arm unit 4 is “intermediate position”. If it is not “intermediate position”, the process proceeds to step S68, and link arm unit 4 moves up. If it is “intermediate position”, the process proceeds to step S69, and it is determined whether or not the turning angle of the link arm unit 4 is “intermediate position”. If it is not the “intermediate position”, the process proceeds to step S70, the link arm unit 4 is turned to the intermediate position, and the process proceeds to step S69. If it is “intermediate position”, the process proceeds to step S71, and it is determined whether or not the angle of the link arm portion 4 is 0 °. If it is not 0 °, the process moves to step S72, and the link arm unit 4 is lowered. If it is 0 °, the process proceeds to step S73.
Referring to FIG. 33, it is determined in step S73 whether the cycle is stopped. If not stopped, the process returns to step S31 (see FIG. 25), and the entry into the human hole P is made again. If it is stopped, the “run” button is turned off in step S74, and this cycle is ended. This cycle stop is made based on an instruction from the “stop” button 314 on the operation screen 300.

(Operation of the main machine S)
