Description

  The present invention relates to an improvement of a multi-axis continuous wall groove excavator of an all-hydraulic drive system, and a wall having a predetermined size is controlled by controlling the excavation posture and penetration direction of the excavator body using a single inclination angle meter. The present invention relates to a multi-axis continuous wall groove excavator capable of drilling grooves with high accuracy and efficiency.

  In general, when constructing foundation piles or continuous walls in the ground, first use a drilling machine to puncture a hole or wall groove of a predetermined shape in the ground, and then excavate the hole or groove into the cement material. A pile body or wall body of a predetermined size is formed by stirring, pouring, or injecting a steel material for a strut and cement milk into the inside after excavation of a hole or a groove. Therefore, in order to construct a foundation pile or continuous wall as designed, it is inevitably necessary to drill excavation holes and excavation grooves having highly accurate shape dimensions.

  Therefore, for example, in a vertical excavator (Japanese Patent Laid-Open No. 2010-77598) in which the casing 30 and the excavating rod 31 are press-fitted into the ground as shown in FIGS. An inclinometer 32 is attached to the mast 33, and an inclination angle between the casing 30 suspended and supported on the mast 33 via a guide rail 34 and a vertical line is detected, and the casing 30 and the excavation head are detected according to the detected inclination angle. The traveling direction of the excavation head 35 is adjusted by appropriately operating a hydraulic cylinder 36 disposed between the two through a universal joint. 7 and 8, 38 is a base machine, 39 is a top support bracket, 50 is a wire rope, 51 is a rotary drive device, 52 is a guide plate, 53 is a cutting blade, and 54 is a drilling hole.

  Similarly, FIG. 9, FIG. 10 and FIG. 11 show an example of a so-called horizontal multi-axis type continuous wall groove excavator. The excavator main body 43 is suspended from a boom 41 of a base machine 40 via a rope 42. The groove hole 46 is excavated by the cutter drum 45 that is supported by being lowered and arranged in parallel at the tip of the excavator main body 43. That is, the excavator main body 43 includes a square columnar support base 44, two cutter drums 45 provided below the support base 44, and the cutter drum 45 supported on the support base 44 in a swingable manner via a hydraulic jack 45a. The slot 46 is excavated by rotating the cutter drum 45 by a hydraulic motor (not shown).

  Further, as shown in FIG. 11, an adjustment flap 49 and a hydraulic jack (not shown) are provided at the four corners of the outer peripheral surface of the support frame 44 that supports the cutter drum 45 at predetermined intervals in the vertical direction. A total of eight direction correcting devices 47 provided are provided, and an inclination angle meter 48 attached to the support base 46 is used to adjust the inclination angle between the support base 46 suspended and supported by the boom 42 and the vertical line. To detect. Then, the operator operates the hydraulic jack of the direction correcting device 47 according to the detected inclination angle to adjust the protruding amount of the adjustment guide flap 49, and the upper and lower of both cutter drums 45 by the hydraulic jack 45a of the coupling mechanism. By finely adjusting the direction position, the descending direction of the support gantry 46 is controlled, and the traveling direction of the support gantry 46 is corrected in the direction in which the inclination angle becomes small.

Each of the conventional excavators corrects the traveling direction of the excavation head 35 and the descending direction of the support base 46 based on the inclination angle measured by the inclination angle meter. Therefore, a straight groove having a predetermined cross-sectional shape at a preset position can be efficiently excavated, and excellent practical utility can be achieved.
However, since the tilt angle meter used is configured to measure the tilt angle with respect to only one of the X, Y, or Z axes, in order to drill a more precise slot Has a problem that a large number of tilt angle meters must be installed. That is, in order to adjust the tilt angle with respect to the two axes in the X-axis direction and the Y-axis direction, at least two tilt angle meters are required, and to adjust the tilt angle with respect to the three axes of the X, Y, and Z axes. Requires at least three tilt angle meters.

  Further, in order to increase the measurement accuracy of the tilt angle and accurately drill the slot closer to the design dimension, the tilt angle meter is provided in a plurality of stages at predetermined intervals in the vertical direction on the casing 30 and the support frame 46. Is desirable. For example, when a tilt angle meter for one axis is provided on the support base 46 at intervals of 10 meters and the traveling direction of the support base is adjusted along the X, Y, and Z axis directions, the support base 44 having a height of 20 meters is provided. Or, in the case of the casing 30, an inclination angle meter of at least 2 stages × 3 units = 6 units (2 stages × 2 units = 4 units in the case of control only in the directions of the two axes X and Y) is necessary. Become.

Japanese Patent Laid-Open No. 2110-77598 JP-A-8-27834 JP-A-8-270006

  The present invention has the above-mentioned problem in the conventional continuous wall groove excavator of this type, that is, the casing for excavation and the support frame that penetrates into the ground are long, and the tilt angle meter to be used is uniaxial. In order to control the penetration direction of the support frame with high accuracy and accuracy, a large number of tilt angle meters are attached to the support frame etc. It is necessary to measure the angle of inclination of each axis of Z and solve the problem that it is difficult to reduce the cost of equipment and maintenance. Reduce the total number of inclinometers required. In addition, the main object of the invention is to provide a continuous wall groove excavator capable of greatly reducing the equipment cost and failure frequency of the tilt angle meter by making the installation location more favorable. is there.

Thus, in recent years, a so-called three-axis tilt angle meter has been developed which can measure the tilt angles of the X and / or Y axes or the X, Y and Z axes with a single tilt angle meter.
However, since this type of tilt angle meter is a precision electronic device, it is as severe as that near the lower end portion of the casing 30 and the lower end portion of the support frame 44, like the tilt angle meter in a conventional excavator. It cannot be installed at various working conditions. As a result, in the area of wall groove excavators for underground continuous walls, this type of three-axis tilt angle meter that detects the tilt angles with respect to the X, Y, and Z axes, respectively, has not been used at all. Not shown.

  On the other hand, in the field of wall groove excavators for underground continuous walls, the development of so-called low-empty wall groove excavators, which can excavate in narrow spaces such as under guards and underpasses with high efficiency in recent years, has been strong. It is requested. Specifically, the excavator has a total height of 6 m or less and a working width of 5 m or less, and can perform not only vertical excavation but also oblique excavation, and it has a thickness of 300 to 1000 mm, a length of 2000 to 3000 mm, and a depth of 50 to There is a strong demand for materials capable of excavating about 80m of wall grooves.

By the way, in the continuous wall groove excavator having the specifications as described above, the external dimensions of the excavator main body composed of the square support frame and the rotary excavating blade are inevitably suppressed to about 3 m × 3 m × 1 m or less. As a result, the number of inclinometers that can be mounted is greatly limited.
However, due to the short height of the support frame, there is a large difference between the measured values of the tilt angle at both positions, even if the tilt angle meter is installed near the upper end of the support frame, not near the lower end. There will be no.
That is, even if an inclination angle meter is installed at a location with a relatively good working environment condition at the upper end of the support frame, the inclination angle of the support frame with respect to the vertical line can be measured relatively accurately. Therefore, it is possible to detect the tilt angle of the support frame with respect to the directions of the X, Y, and Z axes with high accuracy by installing one tilt angle meter that can detect the tilt angles with respect to the X, Y, and Z axes. I was inspired by that.

The present invention was created based on the above-described idea, and the invention of claim 1

The basic configuration of the invention is to operate the hydraulic jack to control the penetration direction and the penetration posture of the excavator body into the ground.

  According to a second aspect of the present invention, in the first aspect of the invention, the five vertical digging blades are provided in parallel, and the tilt angle meter is a tilt angle meter that detects tilt angles with respect to the X axis, the Y axis, and the Z axis. In addition, an adjustment guide plate is disposed on one or both of the upper and lower sides of the support frame so as to be extrudable by a hydraulic jack.

  According to a third aspect of the present invention, in the first aspect of the present invention, the tilt angle meter is horizontally disposed and fixed inside the storage box through an anti-vibration rubber having a semicircular cross section. .

  In the present invention, a tilt angle with respect to each desired axial direction is measured with a single tilt angle meter. Therefore, it is possible to accurately control the advancing direction and excavation posture of the operating excavator body with a single tilt angle meter without using a large number of tilt angle meters as before. It is possible to reduce the total equipment costs and repair costs.

  In addition, when adjustment guide plates are provided on the front, back, and both sides of the support platform that forms the excavator body, a more accurate wall groove is drilled with a single tilt angle meter. It becomes possible to do. There are few occurrences of breakdowns and maintenance-free operation is possible.

  Furthermore, since an airtight storage box storing the tilt angle meter is installed on the upper surface of the support frame, the tilt angle meter is relatively less likely to be damaged during the operation of the excavator body 1. Troubles related to metering are greatly reduced.

  The fixing guide plate and the adjustment guide plate are in sliding contact with the inner wall surface of the wall groove during excavation while the excavator body 1 penetrates into the ground, and the excavator is operated by operating the hydraulic jack 23 of the adjustment guide plate. The traveling direction and the traveling posture of the main body 1 are controlled.

  These controls are performed automatically or manually by adjusting the operation of the hydraulic jack of each adjustment guide plate using an angle detection signal of an inclination angle meter (described later) attached to the upper wall surface of the support frame. When high-precision drilling is required depending on the ground where the wall groove is drilled and other work conditions, angle control in the X, Y, and Z-axis directions is also possible. The angle control is performed in the X and Y axis directions, or only in the Y axis direction, or only in the X axis direction.

  In the present invention, a mounting portion B of the tilt angle meter is provided on the upper wall surface of the support base 9, and inside the steel storage box 4 formed airtight as shown in FIGS. 5 and 6, An inclination angle meter 24 is supported and fixed in a horizontal manner via a vibration isolating rubber 25. In FIGS. 5 and 6, 26 is a support plate, 24a is an upper lid, 24b is a cable outlet, and the anti-vibration rubber 25 is formed in a form in which a ring body of a rubber pipe is halved on a horizontal plane. ing.

  The tilt angle meter 24 detects so-called triaxial angular velocities and accelerations, and based on the detected values (X-axis output value, Y-axis output value and Z-axis output value) of these three-axis angular velocities and accelerations, The tilt angle Φx (roll angle) in the direction, the tilt angle Φy (pitch angle) in the Y-axis direction, and the tilt angle Φz (yaw angle) in the Z-axis direction are calculated by the processor and output as digital and / or analog signals. This is an electronic tilt angle meter. In this embodiment, an AMU-Lite tilt angle meter (manufactured by Sumitomo Precision Industries, Ltd.) is used.

  The tilt angle meter 27 is formed in a box shape having outer dimensions of a lateral width of 53 mm, a vertical width of 32 mm, and a height of 29 mm, and is housed in the storage box 24.

  When building an underground continuous wall or the like using the multi-axis continuous wall groove excavator according to the present invention, as shown in FIG. 1, the excavator main body 1 suspended from the center of the upper surface of the support base 9 is supported. 1, the excavation is rotated in the direction of the arrow in FIG. 1 by driving the hydraulic motors 10 a and 10 b, and the excavator body 1 is inserted into the ground by its own weight. In addition, since each construction method, such as discharge | excavation soil and muddy water discharge, the stabilization of the ground of an excavation location, and the formation of a wall body in a wall groove, is well-known, the description is abbreviate | omitted here.

  The excavator main body 1 penetrating into the ground advances into the ground in a vertical posture by sliding while the fixed guide plates and the adjusting guide plates are in contact with the inner wall surface of the excavated wall groove. Further, the tilt angle meter 27 determines the attitude of the excavator main body 1 that moves forward, the tilt angle Φx (roll angle) in the X-axis direction, the tilt angle Φy (pitch angle) in the Y-axis direction, and the tilt angle Φz (yaw in the Z-axis direction). The angle is measured and output to the controller side continuously or at regular time intervals.

  The advancing direction of the excavator main body 1 and the attitude at the time of advancing vary depending on the excavation status of each excavating blade and the ground condition. The advancing direction of the excavator body 1 and the attitude at the time of advancing are recognized as changes in the inclination angle, and when the inclination angle signal from the inclination angle meter 27 exceeds a preset set value, An appropriate hydraulic jack 23 is activated, and the changed inclination angle of the excavator body 1 is returned to the set angle.

  For example, when the axial direction of the tilt angle meter 7 is determined as shown in FIG. 12, the tilt angle Φy in the Y-axis direction and / or the tilt angle Φz in the Z-axis direction of the excavator body 1 exceeds the set value. When changed, the amount of expansion / contraction of the upper adjustment guide plates 18a and 18b and the lower adjustment guide plates 19a and 19b on the front side and the back side of the support base 9 is adjusted, and these are pulled back below the set angle. When the tilt angle Φz in the X-axis direction exceeds the set angle, the expansion / contraction amount of the side upper adjustment guide plates 21a and 21b or the side lower adjustment guide plates 22a and 22b provided on both side surfaces of the support base 9 is adjusted. These are pulled back below the set angle.

  As described above, by adjusting the pressing force (reaction force from the inner wall surface of the wall groove) applied to each part of the support base 9 by operating the adjustment guide plate at an appropriate position by the angle detection signal from the tilt angle meter 27. Thus, the support frame 9 can be moved straight in the vertical direction or in a preset inclination direction. Further, it is possible to advance the instruction stand 9 along a curve having a preset curvature.

  In addition, since the mounting portion B of the tilt angle meter 27 is provided on the upper wall surface of the indicating stand 9, the environmental conditions are better than when the tilt angle meter 27 is provided below the indicating stand 9, and the tilt angle meter is less damaged. In addition, since the height of the support base 9 is relatively short, there is almost no difference in measurement error or measurement sensitivity of the tilt angle meter 27 depending on the mounting position of the mounting portion B in the height direction.

  The present invention can be applied not only to excavation of wall grooves for continuous underground walls, but also to drilling of underground wall grooves for all uses.
