Detailed Description
The present invention will be described in detail by way of embodiments for carrying out the invention which are shown in the accompanying drawings. Here, the up/down direction refers to a direction in which the work vehicle body ascends/descends. The left-right direction refers to the left/right direction (fig. 2 and 4) as viewed in plan. The front/rear direction means an up/down direction as viewed in a plan view.
According to a first embodiment for implementing the present invention shown in fig. 1 to 8, reference numeral 1 denotes a slope work vehicle capable of working on a slope 2 having a slope frame 2a formed thereon, as shown in fig. 3 and 4.
As shown in fig. 1, the slope working vehicle 1 is constituted by: work vehicle body 3, telescoping mechanism 4, tire 6, winch 7, a plurality of supports 9, a plurality of sensors 10, control device 11, drilling device 12, and drop-off prevention roller 14. The telescopic mechanism 4 is provided at the left and right portions of the work vehicle body 3 and is capable of being expanded and contracted according to the width of the bezel 2 a. Tires 6 are provided at front and rear portions of the telescopic mechanism 4, each having a tire hydraulic cylinder 5 therebetween. The tire hydraulic cylinder 5 is capable of extending and contracting in the up/down direction. The winch 7 is mounted on the work vehicle body 3. A plurality of bearings 9 are provided on the bottom surface of the work vehicle body 3, each having a bearing cylinder 8 therebetween. The support hydraulic cylinder 8 can be extended and contracted in the up/down direction. The plurality of support members 9 can support the work vehicle body 3 when the telescopic mechanism 4 is telescopic in the right-left direction. A plurality of sensors 10 (for example, four sensors 10) are provided in the front-rear-left-right direction in the bottom surface portion of the work vehicle body 3. The control device 11 receives a signal from the sensor 10, and causes the operation rod 5a of the tire cylinder 5 provided with the tire 6 to extend and contract based on the signal, thereby making the work vehicle body 3 substantially parallel to the slope 2 or the bezel 2 a. The drilling device 12 is provided on the work vehicle body 3. The anti-drop rollers 14 are respectively installed near the tires 6 with the position adjusting device 13 therebetween.
The expansion mechanism 4 is constituted by a tire mounting portion 16 and a tire cylinder 5. The tire mounting portions 16 are mounted on the left and right portions of the work vehicle body 3 with the telescopic mechanism hydraulic cylinder 15 therebetween. One end of the tire cylinder 5 is attached to the front and rear portions of the tire mounting portion 16, and the other end (the operating lever 5a) is attached to the tire 6. The tire hydraulic cylinder 5 is capable of extending and contracting in the up/down direction. The tire mounting portion 16 can be extended and contracted in the left/right direction by the extension and contraction mechanism hydraulic cylinder 15 based on the width of the bezel 2 a. The sensor 10 is a parallel sensor provided in the front-rear-left-right direction of the work vehicle body 3. According to the present embodiment, a noncontact optical sensor is used. Each sensor 10 outputs a measurement value (distance) between the work vehicle body 3 and the slope 2 or the bezel 2a measured by the optical sensor to the control device 11. As a method of connecting the sensor 10 to the control device 11, a wired or wireless connection may be considered. According to the present embodiment, each sensor 10 is wirelessly connected to the control device 11.
The control device 11 receives signals from the sensor 10. The control device 11 calculates the inclination of the work vehicle body 3 with respect to the slope 2 or the bezel 2a based on the difference between the measurement values transmitted from the sensor 10. The control device 11 performs control so that the work vehicle body 3 becomes substantially parallel to the slope 2 or the bezel 2a by extending and contracting the operating rod 5a of the tire hydraulic cylinder 5 provided with the tire 6 so that the difference is reduced. According to the present embodiment, the control device 11 is not mounted on the work vehicle main body 3. In contrast, the control device 11 is installed in an operation terminal (not shown) through which the operator operates the slope working vehicle 1. The control device 11 receives signals from the sensors 10 wirelessly and automatically calculates the inclination and controls the extension and contraction of the tire hydraulic cylinder 5.
In the case where the inclination of the slope 2 or the like is fixed, an accelerator sensor or the like may be used as the sensor 10. Control may be performed so that the work vehicle main body 3 is at a fixed angle.
The drilling device 12 is a drilling device that has been used since the past. The drilling device 12 is composed of a support base 19, a support base hydraulic cylinder 20, a swing arm 23, a guide housing 24, and a hydraulic rock drill 25. The support base 19 is rotatably mounted to the mounting base 17 by a pivot pin. The mounting base 17 protrudes from the upper front portion of the work vehicle body 3. The support base hydraulic cylinder 20 rotates the support base 19. Swing arm 23 is mounted to support base 19 with swivel mechanism 22 therebetween. The rotation mechanism 22 uses the support base hydraulic motor 21 and rotates the swing arm 23 in the left-right direction. A guide housing 24 is selectively installed at a front end portion of the swing arm 23, and a rock bolt insertion hole or an earth anchor insertion hole is formed in a bezel 2a formed on the slope 2. A hydraulic rock drill 25 is mounted to the guide housing 24.
Since the drop-off prevention roller 14 is attached to the tip of the position adjustment hydraulic cylinder 26 and the operating rod 26a of the position adjustment hydraulic cylinder 26 is extended and contracted in the up/down direction, each position adjustment device 13 is configured to be able to move the drop-off prevention roller 14 in the up/down direction. The position adjusting hydraulic cylinder 26 is mounted inside the tire hydraulic cylinder 6.
Since the anti-drop rollers 14 are positioned to protrude below the tire 6, each anti-drop roller 14 comes into contact with the side wall of the lower inclined frame 2a of the tire 6 when the slope work vehicle 1 travels on the inclined frame 2 a. As a result, the tire 6 and the drop-off prevention roller 14 are clamped to the bezel 2 a. The tire 6 is always positioned on the bezel 2a, and the tire 6 can be prevented from falling off from the bezel 2 a.
Further, when the distance between the inclined frames 2 is widened and narrowed during traveling of the slope working vehicle 1, the drop-off preventing roller 14 can come into contact with the sidewall of the inclined frame 2a in the lower portion of the tire 6 by the hydraulic cylinder 15 for the telescopic mechanism of the telescopic mechanism 4 which is telescopic in the left-right direction.
When the slope working vehicle 1 runs on the ground (including a slope not provided with the slope frame 2 a), each of the anti-drop rollers 14 is retracted by the position adjusting hydraulic cylinder 26 to be located above the lower portion of the tire 6. Thereby preventing the drop-off prevention roller 14 from obstructing the travel of the slope working vehicle 1.
The diameter of each tire 6 is twice or more the height of the bezel 2 a. Therefore, the tire 6 can easily traverse the inclined frame 2 a.
When work is performed on the slope 2 provided with the slope frame 2a, the slope work vehicle 1 is located at the lower portion of the slope 2. The respective end portions of the wire ropes 27 of the left and right winches 7 are fixed to a main holder 28 on the upper portion of the inclined plane 2. When the wire rope 27 is fixed to the main holder 27, the winch 7 is wound up and the slope working vehicle 1 advances. By the telescopic mechanism 4 being telescopic in the left/right direction so that each of the four tires 6 is placed on the inclined frame 2a, the telescopic mechanism 4 can be adjusted so that the interval in the left/right direction between the tires 6 matches the width of the inclined frame 2 a.
In addition, the operating rod 8a of the support hydraulic cylinder 8 of the support 9 is extended and a state is achieved in which the work vehicle body 3 is supported by the support 9 (the tire 6 is in the air). In this state, one tire mounting portion 16 (e.g., the tire mounting portion 16 on the left side) of the expansion and contraction mechanism 16 is expanded. The operating rod 8a of the support hydraulic cylinder 8 contracts and the tire 6 is grounded. One of the tire mounting portions 16 contracts and the other tire mounting portion 16 (e.g., the tire mounting portion 16 on the right side) extends. In this state, a state in which work vehicle body 3 is supported by support 9 is achieved again (tire 6 is in the air). After the other tire mounting portion 16 is contracted, when the tire 6 is grounded, the work vehicle body 3 itself can be moved in the left-right direction by the stay 9 and the expansion mechanism 4.
After all four tires 6 are placed on the bezel 2a, the position adjusting cylinder 26 is extended and the drop-off preventive roller 14 is brought into contact with the side wall of the lower bezel 2a of the tire 6. At this time, the lateral position of the drop-off preventing roller 14 can be finely adjusted by extending and contracting the extending and contracting mechanism 4 in the left-right direction.
In a state where the support cylinder 9 provided with the support member 9 is extended, the telescopic mechanism 4 is extended and contracted in the left-right direction, the sloping work vehicle 1 can also be moved left and right on the sloping frame 2a, and the support member 9 is grounded on the sloping frame 2 or the sloping frame 2a and supports the work vehicle main body 3.
When the slope working vehicle 1 reaches the working position, the support base hydraulic cylinder 20 and the rotation mechanism 22 of the drilling device 12 are operated. The swing arm 23 is rotated and set at a position where a rock bolt insertion hole or an earth anchor insertion hole can be formed. The hydraulic rock drill 25 is driven and a rock bolt insertion hole or an earth anchor insertion hole is formed.
[ other embodiments for carrying out the invention ]
Next, another embodiment for carrying out the present invention shown in fig. 9 to 12 will be described. In the description of the other embodiments for carrying out the invention, the same components as those used for carrying out the first embodiment of the invention are given the same reference numerals. Redundant description is omitted.
According to the second embodiment for carrying out the present invention shown in fig. 9 to 12, the main difference from the first embodiment for carrying out the present invention is that a plurality of tires capable of supporting the work vehicle body 3 when the telescopic mechanism 4 is telescopic in the right-left direction are used as the support 9A. The slope working vehicle 1A can also achieve the same operational effects as those of the first embodiment of the present invention.
In addition, the slope working vehicle 1A according to the present embodiment has eight tires. That is, the slope working vehicle 1A has tires 6 provided in the front and rear portions of the telescopic mechanism 4 with the tire hydraulic cylinders 5 therebetween. The tire hydraulic cylinder 5 can be extended in the up/down direction. The slope working vehicle 1A also has tires that are respectively provided in the working vehicle main bodies 3 near the tires 6 and that serve as supports 9A.
The tyre cylinder 5 of the tyre 6 and the nearby support cylinder 8 can be connected. When the tire hydraulic cylinder 5 is extended, the nearby support hydraulic cylinder 8 can be contracted. In this way, the tire hydraulic cylinder 5 and the nearby shoe hydraulic cylinder 8 are connected by the hose 29, and the slope working vehicle 1 can smoothly travel while crossing the slope frame 2 a.
According to the embodiment of the present invention, the slope working vehicle 1 using the tire having the diameter twice or more the height of the bezel 2a is described. However, the present invention is not limited thereto. Smaller diameter tires may be used.
In addition, according to the embodiment of the present invention, the sloping work vehicle 1 using the drop-off preventive roller that contacts the sloping frame 2a by being extended and retracted in the up-down direction by the cylindrical body is described. However, the present invention is not limited thereto. The anti-drop roller can contact the bezel due to the rotation of the shaft on which the anti-drop roller is mounted.
Further, according to the embodiment of the present invention, there is described the control device which measures the inclination with respect to the inclined surface or the like by using the sensor and automatically performs the control so that the work vehicle main body is substantially parallel to the inclined surface or the like. However, the operator may visually confirm the inclination between the work vehicle body and the inclined surface and perform control by operating the tire hydraulic cylinder so that the work vehicle body is substantially parallel to the inclined surface. Alternatively, a slope working vehicle without using sensors and control devices is also possible.
INDUSTRIAL APPLICABILITY
The present invention is applicable to an industry of manufacturing a slope working vehicle for a case where the slope working vehicle is suspended by a wire rope of a winch and various works are performed on an inclined ground such as a slope.
