Description

[Technical Field]

[0001] The present invention relates to a display system for a pile driver, and more particularly, to a display system for a pile driver provided with a function of supporting a part of construction operations. [Background Art]

[0002] Conventionally, at construction sites where steel pipe pile embedding, ground improvement, and the like are performed, the position of a pile core (the central axis of a pile), which is the construction position, is determined in advance by surveying, and during construction, a construction machine such as a pile driver is moved to the pile core position by an operator's driving operation. For this pile core positioning, generally, the position and orientation of the pile driver are adjusted by moving a lower traveling body composed of left and right crawlers, or rotating an upper rotating body relative to the lower traveling body (see, for example, Patent Document 1).

[0003] In recent years, the informatization of construction at construction sites has progressed, and a dedicated system has been developed and put into use also for pile core positioning. By following the visually displayed guidance screen, an operator of a construction machine can perform smooth driving operation while visualizing the relationship between the current position and the target position (see, for example, Patent Document 2). [Prior Art Documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2011-6880 [Patent Document 2] Japanese Unexamined Patent Application Publication No. 2021-110220 (Fig. 12) [Summary of the Invention] [Problem to be Solved by the Invention]

[0005] The construction position guidance system described in Patent Document 2 moves the current position, displayed as an icon, closer to the construction target position. The icons superimposed on a square grid allow for an intuitive understanding of the required amount of operation. However, the operation of aligning the pile center requires a combined operation of traveling and turning. With the current icon display, due to the operating characteristics of the pile driver, simple linear movement along the grid lines does not occur, and it cannot be said that the visual effect of the grid is fully utilized.

[0006] Therefore, the present invention aims to provide a display system for a pile driver that provides a display that takes into consideration the operator's driving operations and facilitates guidance to the pile center position. [Means for solving the problem]

[0007] To achieve the above objective, the display system for a pile driver of the present invention comprises a receiving unit that acquires position information of a pile driver equipped with an upper rotating body on a lower traveling body, a storage unit that stores construction plan information setting the planned pile burial positions at the construction site, and a controller that displays a screen using the position information acquired by the receiving unit and the construction plan information stored by the storage unit, wherein the controller determines the planned pile burial positions and the actual pile center positions determined from the position information of the pile driver. The aforementioned screen In a display system for a pile driver in which icons are added to the display images inside, the display images are divided by vertical lines and horizontal lines. and are formed in a grid pattern The vertical line is characterized by consisting of multiple straight lines, including a straight line passing through the pivot center of the set upper rotating body and a straight line arranged parallel thereto, and the horizontal line is characterized by consisting of multiple arcs arranged as the circumferential portions of multiple circles of different diameters that are concentric with the pivot center.

[0008] Furthermore, the planned burial locations of the piles and the actual pile center locations are added to the display image as circular icons of different sizes, and the distance between adjacent lines and arcs is equal to the radius of the actual pile center location icon.

[0009] Furthermore, the size of the icons for the planned burial position of the pile and the actual pile center position is set to a difference corresponding to the allowable deviation of the position relative to the planned burial position of the pile, the icon for the actual pile center position has a concentric inner circle with a radius corresponding to the difference corresponding to the allowable deviation of the position, the icon for the planned burial position of the pile has a mark that falls inside the inner circle when it is positioned concentrically with the icon for the actual pile center position, and the display image is further divided by two linear inner circle tangents that are parallel to the straight line passing through the pivot center and are tangent to the circumference of the inner circle, and two arc-shaped inner circle tangents that are tangent to the circumference of the inner circle and are located on the circumference of a circle concentric with the pivot center.

[0010] In addition, the controller is characterized by changing the display color of the interlinear region when the marker is located within the interlinear region between the two linear inner circle tangents, and changing the display color of the intercircular region when the marker is located within the intercircular region between the two arc-shaped inner circle tangents. [Effects of the Invention]

[0011] According to the display system for pile drivers of the present invention, icons for the planned pile installation position and the actual pile center position are added to the display image for displaying the alignment of the pile center. Furthermore, the vertical lines that demarcate the display image consist of multiple straight lines, including a straight line passing through the pivot center and a straight line arranged parallel to it, and the horizontal lines consist of multiple arcs arranged as the circumferences of multiple circles of different diameters that are concentric with the pivot center. As a result, the amount of operation required for alignment of the pile center can be intuitively grasped from the display of each icon superimposed on the demarcation lines. In particular, the interaction between the icons that move in arcs on the display image in accordance with the rotational movement of the pile driver and the horizontal lines arranged as arcs allows the visual effect of the demarcation lines to be fully realized, thereby contributing to the simplification and high accuracy of pile center alignment.

[Modes for carrying out the invention]

[0013] Figures 1 to 7 show an embodiment of applying the present invention to a small pile driver. As shown in Figure 1, the pile driver 11 is a dual-purpose machine capable of switching between steel pipe pile construction and ground improvement construction, comprising: a base machine 14 configured by a lower traveling body 12 provided with crawlers and an upper revolving structure 13 revolvably provided on the lower traveling body 12; a leader 15 erected at a front portion of the upper revolving structure 13; and a luffing cylinder 16 that supports the leader 15 from the rear. A leader support 17 that supports the leader 15 to be capable of luffing is provided at the front portion of the upper revolving structure 13, a driver's cab 18 is provided at a right side portion of the upper revolving structure 13, and an equipment room 19 housing an engine and a hydraulic unit is provided at a left side portion thereof, respectively.

[0014] The leader 15 is formed by connecting a plurality of leader members each having a square tubular cross-section to each other, and is rotatably attached to a vehicle width-direction support shaft provided on the leader support 17. A top sheave 20 around which a hoisting rope is wound is disposed at an upper end portion of the leader 15, and an openable / closable anti-sway member 22 for preventing swaying of the steel pipe pile 21 is disposed at a lower front portion of the leader 15, respectively. At a center of a front surface of the leader 15, a rack gear 23 as a component of a rack-and-pinion lifting device is provided, and at front end portions of both side surfaces, a pair of left and right guide pipes 24, 24 are provided, each continuously provided over an entire length of the leader 15.

[0015] An auger 25, which is an example of a rotary drive device, is provided with a pair of left and right guide gibs 25a, 25a that are in sliding contact with the guide pipes 24, 24, protruding rearward, and moves up and down along the front surface of the leader 15 by rotationally driving a pair of left and right pinions (not shown) meshing with the rack gear 23 by a hydraulic motor 25b for lifting and lowering the auger.

[0016] When performing steel pipe embedding work, the prepared steel pipe pile 21 is lifted by a rope hanging from a top sheave 20, and then the upper end is connected to a drive rod (rotary drive shaft) 26 via an adapter 27, while the lower end is held by a vibration stopping member 22. The installed steel pipe pile 21 is rotationally driven by a hydraulic motor 25c for driving an auger, and is pressed into the ground by lowering the auger 25.

[0017] In the driver's cab 18, a plurality of devices including a plurality of operation levers, operation pedals, push button switches, a display and the like for performing operations such as traveling, turning, and lifting / lowering and rotational driving of the auger 25 are collectively arranged in the vicinity of the driver's seat in consideration of operability. Furthermore, a control device electrically connected to these devices and mainly composed of a controller (CPU) that performs various arithmetic processes such as data processing and determination is provided.

[0018] The control device constitutes a display system that supports pile core position alignment at a construction site based on vehicle body position information of the pile driver 11, and as shown in Fig. 2, comprises the controller functioning as an actual pile core position calculation unit 28, a construction management device 29 which is a storage unit for storing various data, and a display 30 that provides guidance support for pile core position alignment to an operator through a display screen and allows the operator to check construction results. In addition, signals from various sensors that detect the operating state of the pile driver 11 are input to the actual pile core position calculation unit 28. Examples of the sensors include a main body inclinometer 31 provided on the upper rotating body 13 and a leader inclinometer 32 provided on the leader 15. The detection values of the main body inclinometer 31 and the leader inclinometer 32 are acquired as posture information of the pile driver 11 and used for execution of a control program.

[0019] The construction management device 29 is configured to download and store control programs and construction plan data, which are construction plan information, via a communication connection. The construction plan data is pre-entered into a computer in the office based on a construction plan document created after investigating the location and soil conditions of the construction site, and includes various construction target values ​​such as pile numbers, depth, feed speed, rotation speed, and cement grout flow rate, which are associated with the pile numbers. The input of construction plan data is performed by inputting pile position data in comparison with the construction drawings, and specifically, the planned location for burying the piles is specified in two-dimensional coordinates as a relative position (distance) from the origin of the coordinate system.

[0020] The created construction plan data is uploaded to a data server on the network, along with location information of the construction site address, machine number information of the pile driving machine 11 to be used, and vehicle body external shape information including mechanism information, such as information on the turning radius. In addition, construction management programs for the construction methods to be implemented based on the construction plan data, such as ground improvement methods, precast pile methods, or cast-in-place pile methods, as well as data for the setting parameters of said construction management programs, are also created and uploaded to the data server in the same manner.

[0021] Vehicle position information is acquired using well-known GNSS (Global Navigation Satellite System) technology. For example, the pile driver 11 is equipped with a first positioning device 33 having an antenna 35 and a second positioning device 34 having an antenna 36 as receiving units on the upper rotating body 13 of the pile driver 11. While receiving radio waves from GNSS satellites, the position information of the antennas, which changes as the pile driver 11 travels and rotates, is acquired. The actual pile center position calculation unit 28 calculates the position and orientation of the upper rotating body 13 from the positional relationship of the two antennas 35 and 36, which are separated in the front-rear direction. Furthermore, by taking into account the attitude information acquired by the main inclinometer 31 and the leader inclinometer 32, the position of the central axis of the steel pipe pile 21 (various construction members) on the ground, i.e., the actual pile center position C0, is determined (Figure 1).

[0022] The following describes the pile center alignment support function (pile center guidance) provided by the display system. First, when the pile driver 11 is brought to the construction site and its engine is started, the system is activated and the current vehicle position information of the pile driver 11 is acquired by the first positioning device 33 and the second positioning device 34. In addition, construction plan data is automatically downloaded corresponding to the construction site where the pile driver 11 is located, and various information such as the position information of each pile number and the vehicle body shape information is acquired. Furthermore, the actual pile center position calculation unit 28 determines the actual pile center position C. Based on the pile position data and vehicle body position data of the first pile number, the shortest movement path toward the planned pile burial location is set, and a two-dimensional image showing the shortest movement path is displayed on the display 30 as a guidance screen.

[0023] As the pile driver 11 is driven and approaches the planned pile installation location (target pile center position), the guidance screen switches to an approach screen (pile center position guidance screen) that enlarges the surrounding area including the planned pile installation location P and the actual pile center position C, as shown in Figure 3. Here, although details will be described later, the planned pile installation location P and the actual pile center position C are images of a common pile cross-section and are added to the displayed image as circular icon image data of different sizes.

[0024] As shown in Figure 4, the displayed image on the approach screen is formed in a roughly grid-like manner by dividing a rectangular display area 37 with vertical and horizontal lines. As also shown in Figure 5, the vertical lines consist of multiple straight lines, including a straight line 38 passing through the pivot center (rotation axis) PV of the set upper rotating body 13 and the actual pile center position C0, and a straight line 39 arranged parallel to it. On the other hand, the horizontal lines consist of multiple circular arcs 40 arranged as the circumferential portion (part of the circumference) of multiple circles of different diameters that are concentric with the pivot center PV. Furthermore, the distance between adjacent multiple straight lines 38, 39 and multiple circular arcs 40 is set to be equal to the radius of the icon for the actual pile center position C (Figure 4).

[0025] The straight line 38 passing through the pivot center PV is set as a bisecting line that divides the display area 37 into two equal parts left and right, and of the multiple circular arcs 40, one of them is set as the pivot trajectory S. The pivot trajectory S is a circular arc corresponding to the pivot radius R (Figure 1), which is the horizontal distance between the pivot center PV of the upper pivot body 13 and the actual pile center position C, and is fixed in the center of the display area 37 together with the actual pile center position C. Then, with the icon center of the actual pile center position C coincided with the intersection of the straight line 38 and the pivot trajectory S, the display area 37 is divided into sections with a pitch that matches the icon size (circle diameter and radius) of the actual pile center position C.

[0026] Here, when the lower traveling body 12 is operated or the upper rotating body 13 is operated, the icon for the actual pile center position C is the image on the side that is fixed together with the lane markings, so the image on the side that is moved, that is, the image that appears to be moving, becomes the icon for the planned pile burial position P. For example, when the system is operated to rotate in either the left or right direction (arrow direction in Figure 5), the direction of movement of the actual pile center position C corresponds to the direction along the rotation trajectory S (arrow direction in Figure 4), but in terms of appearance, only the planned pile burial position P moves relative to the actual pile center position C.

[0027] As a result, the operator of the pile driver 11 can focus on the actual pile center position C on the screen to obtain the visual effect of demarcation lines consisting of vertical and horizontal lines, and can identify the relative positional relationship between the actual pile center position C and the planned pile embedding position P during each travel and rotation operation. In particular, during rotation operations, the destination of the planned pile embedding position P, that is, the destination of the arc-shaped movement along the rotation direction, can be estimated in accordance with the actual operation of the machine.

[0028] In the following sections, the specific shapes of the icons for the planned pile installation location P and the actual pile center location C, as well as the corresponding shapes of the lane markings, will be explained with reference to Figures 6 and 7.

[0029] As shown in Figure 6, the planned pile burial position P and the actual pile center position C have different display colors that make them easily distinguishable from each other. The size of each icon is set to differ according to the allowable deviation value relative to the planned pile burial position P, i.e., according to the set management standard. As shown in Figure 6(a), as an example, if the pile diameter is set to D and the allowable value to be D / 8, the icon for the actual pile center position C is displayed with a diameter of 5D / 4 (D+D / 8+D / 8), which is the pile diameter plus a deviation of 1 / 8 in each direction (up, down, left, and right). Furthermore, the icon for the actual pile center position C has a concentric inner circle with a radius equal to the difference according to the allowable value, i.e., an inner circle with a radius of D / 8 and a diameter of D / 4 (D / 8+D / 8), and is displayed as a double circle paired with an outer circle with a diameter of 5D / 4.

[0030] On the other hand, the icon for the planned pile burial location P is displayed in a size corresponding to the pile diameter D, as shown in Figure 6(b), and as a marker indicating the center (pile core), two intersecting line segments extending diagonally across the section, i.e., a roughly X shape, are displayed. The display color for the planned pile burial location P is, for example, a highly visible red, and the inside of the circle is lightly filled. Also, since the icon for the planned pile burial location P is sized according to the pile diameter D, it will be set to be smaller than the icon for the actual pile core location C by a difference (D / 8) according to the allowable value. Furthermore, as shown in Figure 6(c), when each icon is positioned concentrically with the others, the marker (X shape) for the planned pile burial location P is placed inside the inner circle (radius D / 8) of the actual pile core location C, and the lines representing the shapes of each icon do not overlap, so the display does not disappear.

[0031] Based on the specific shape of each icon, the display area 37 is further divided, as shown in Figure 7, by two linear inner circle tangents 41, 41 that are parallel to the straight line 38 passing through the pivot center PV and tangent to the circumference of the inner circle, and by two arc-shaped inner circle tangents 42, 42 that are tangent to the circumference of the inner circle and are located on the circumferential portion (part of the circumference) of a circle concentric with the pivot center PV. When the marker (× shape) for the planned pile burial position P is placed within the linear region 43 between the two linear inner circle tangents 41, 41, the display color of the linear region 43 is changed to a color different from the background color (e.g., white) and the display color of the planned pile burial position P (e.g., light red) (e.g., blue), as shown in Figure 7(a). On the other hand, when the marker is placed within the arc region 44 between the two arc-shaped inner circle tangents 42, 42, the display color of the arc region 44 is changed in the same manner, as shown in Figure 7(b).

[0032] During the pile center alignment stage, the operator of the pile driver 11 appropriately controls the movement of the lower traveling body 12 and the rotation of the upper rotating body 13 while checking the icon display, bringing the inner circle of the actual pile center position C closer to the mark (X shape) of the planned pile burial position P, as shown in Figure 3. At this time, in the space provided outside the display area 37 of the display image, for example, the magnitude of the deviation in the front-to-back direction (X direction) and the left-to-right direction (Y direction) is displayed numerically, and the necessary driving operations (travel and rotation) are indicated by arrows.

[0033] When the operation is performed from this state and the amount of deviation falls within the management standard of D / 8, the icon for the planned pile burial position P changes its display color from red to blue, indicating that the allowable value for positional deviation has been satisfied. At this time, although not shown in the illustration, the marker (X shape) is in a state where its center coordinates are located within the inner circle (radius D / 8). Thus, when the display color of the icon for the planned pile burial position P changes, the operator of the pile driver 11 determines that the management standard has been met and completes the operation for aligning the pile center position.

[0034] Here, the operation of aligning the pile center requires driving, turning, or simultaneous operation of both, and in situations where visibility is poor, such as at night or in rainy weather, it is necessary to concentrate even more on the driving operation. For example, as shown in Figure 7(a), when the display color of the straight-line area 43 changes, it can usually be determined that the remaining process only requires driving operation. However, the turning angle of the upper turning body 13 relative to the lower driving body 12 of the pile driver 11 is not always in a state of alignment (state in Figure 1), and furthermore, it is susceptible to the effects of the difference in driving force between the left and right crawlers. If a positional deviation occurs due to these factors, the machine may deviate from the route toward the pile center position and the display color may return to its original state. In this case, the operator can immediately know that a positional deviation has occurred by the visual effect of the display area 37, that is, by looking at the change in the display color.

[0035] On the other hand, as shown in Figure 7(b), when the display color of the arc-interval region 44 changes, it can be determined that the remaining process only requires a rotation operation. Since the rotation operation is a simple movement around the rotation center, it has the advantage of not causing the positional displacement that was a problem in the driving operation. Furthermore, the operator can eliminate concerns about positional displacement by seeing the visual effect of the display region 37, that is, by seeing the change in the display color, and can then perform the subsequent pile center alignment operation with a stable rotation operation.

[0036] Construction for the first pile number is performed automatically by the construction management program, acquiring construction data as it runs. Once construction is complete, an operator performs a predetermined switching operation. This switching operation is performed, for example, by pressing the "Guidance Complete" button on the touch panel screen, which switches the screen to guide the next pile number.

[0037] As a result, the control device sets a movement path to the planned burial location of the next pile based on the pile position data and vehicle position data for the next pile number. Then, following the pile center guidance described above, the pile center alignment of the next pile is performed using the same procedure, and the same procedure is performed for the planned burial locations of subsequent piles. In this way, pile center alignment and construction are repeated according to the planned pile burial order. The pile center alignment information obtained at this time (information such as pass / fail judgment) is recorded as part of the construction management information.

[0038] As described above, the display system for the pile driver 11 of the present invention adds icons for the planned pile burial position P and the actual pile center position C to the display image (display area 37) as a display for pile center alignment. The vertical lines that demarcate the display image consist of multiple straight lines 38, 39, including a straight line 38 passing through the pivot center PV and a straight line 39 arranged parallel to it, and the horizontal lines consist of multiple arcs 40 arranged as the circumferences of multiple circles of different diameters that are concentric with the pivot center PV. Therefore, the amount of operation required for pile center alignment can be intuitively grasped from the display of each icon superimposed on the demarcation lines. In particular, as the pile driver 11 rotates, the interaction between the icon for the planned pile burial position P, which moves in an arc on the display image, and the horizontal lines arranged as arcs 40 allows the visual effect of the demarcation lines to be fully realized, thus contributing to the simplification and high accuracy of pile center alignment.

[0039] Furthermore, the planned pile installation location P and the actual pile center location C are added to the displayed image as circular icons. Since the distance between adjacent straight lines 38 and 39, and between adjacent circular arcs 40, is equal to the radius of the icon for the actual pile center location C, it is possible to create sections with a pitch that matches the icon size (circle diameter and radius) of the actual pile center location C. Moreover, because each icon is of a different size, even when icons are close to each other, the area where one icon is not displayed due to overlap is reduced, improving the visibility of the icons themselves and assisting in the operation of aligning the pile center location.

[0040] Furthermore, by creating a difference in size between the icon for the planned pile installation location P and the icon for the actual pile center location C, corresponding to the allowable deviation value relative to the planned pile installation location P, it becomes possible to visually display the allowable error value, making it easy to determine whether the management standards have been met. Moreover, the icon for the actual pile center location C has a concentric inner circle with a radius corresponding to the difference in deviation value, and the icon for the planned pile installation location P has a marker that falls within the inner circle when it is concentric with the icon for the actual pile center location C. Therefore, the operator only needs to focus on the positional relationship between the inner circle and the marker when performing the operation, so even if strict standards are set, pile center alignment can be performed quickly and accurately.

[0041] In particular, since the displayed image is further subdivided by two linear inner circle tangents 41, 41 that are parallel to the straight line 38 passing through the pivot center PV and tangent to the circumference of the inner circle, and by two arc-shaped inner circle tangents 42, 42 that are tangent to the circumference of the inner circle and are concentric with the pivot center PV, the visual effect of the subdivision lines can be made even more fully realized. That is, it becomes possible to grasp the positional relationship between the inner circle and the markers even when they are separated from each other (Figure 7), greatly improving the predictability of pile center alignment for the operator.

[0042] In addition, as part of the image processing performed by the controller, when a marker enters the inter-line region 43 between two linear inner circle tangents 41, 41, the display color of the inter-line region 43 changes, and when a marker enters the inter-arc region 44 between two arc-shaped inner circle tangents 42, 42, the display color of the inter-arc region 44 changes. Combined with improved predictability, this makes it easier to intuitively grasp the changes (progress) in the pile center alignment status.

[0043] Furthermore, in conjunction with the change in display color of the straight-line region 43 and the arc-shaped region 44, the display color of the icon also changes when the tolerance value for positional deviation is satisfied, making it immediately clear that the control standards have been met. Moreover, since the magnitude of the deviation is displayed numerically, it becomes possible to aim for even higher precision (for example, precision on the order of a few centimeters) from the point when the control standards are cleared.

[0044] Furthermore, at construction sites where the planned locations for burying multiple piles are concentrated in a continuous area, routine work has traditionally been performed that involves repeatedly aligning the pile centers. There is a need to shorten this process even further, even by a small amount of time. The present invention can meet the need to reduce man-hours at construction sites where such pile driving machines 11 are used.

[0045] Furthermore, the present invention is not limited to the above-described embodiments, and the display system may be used independently, in addition to being added to an existing construction management system. Also, the screen configuration is merely an example, and the division of the display area and the size and shape of the various icons are arbitrary. When displaying numerical data and other information together, the display area can be divided or combined into a single area.

[0046] Furthermore, the area and icon displays are designed with visibility in mind, and their size can be adjusted as needed according to management standards. The line type and thickness of the area lines, as well as the display colors of various images, can also be set as appropriate. In addition, although a small pile driver was used as an example in the embodiment, the system is not limited to this and can be applied to large pile drivers such as three-point pile drivers, and to ground improvement machines that perform work similar to steel pipe burial.
