The drill bits 26A-26C have drill teeth 28A-2 8C, which protrude from the drill bits 26A-26C and expand the diameter of the drill bits 26A-26C. As shown in Figure 2, the drill teeth 28A-28C slide on the guide grooves 30A-30C. The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) ------------ ---------- Order ------- (Please read the notes on the back before filling this page) 480312 A7 B7 V. Description of the invention (9) (Please read the note on the back? Please fill in this page again), the guide grooves 30A-30C are formed at the front ends of the drill bits 26A-26C, respectively. The guide grooves 30A-30C are formed radially from the center portion of the hammer case 18, and each has an inclined angle with respect to the hammer case 18. Each of the guide grooves 30A-30C and the drill teeth 28A-28C has a tapered cross-section, thereby preventing the drill teeth 28A-28C from slipping off the guide grooves 30A-30C. Stop bits (not shown) are fixed to the bit teeth 28A-28C to adjust their range of movement. And the stopper tip fits with a stopper groove (not shown) on the guide grooves 30A-30C. The stop groove is formed in the guide groove 30A-30C with a predetermined length. Therefore, by moving the stop tip into contact with the front end of the stop groove, the movement of the drill teeth 28A-28C in the front direction can be adjusted. By bringing the back ends 28a-28c of the drill teeth 28A-28C into contact with the back end faces 30a-30c of the guide grooves 30A-30C, the movement of the drill teeth 28A-28C in the rear end direction can be adjusted. When the front end hammer 10 is moved in the rearward direction (right-hand direction in FIG. 2), the drill teeth 28A-28C having the above structure protrude from the outer periphery of the drill bits 26A-26C, thereby expanding the outer diameter of the drill bits 26A-26C.

The gas supply pipes 3A, 3B and 3C are hollow and have the same length as the main pipe 2. The three gas supply pipes 3A, 3B, and 3C are parallel to the main pipe 2 and spaced a predetermined distance apart from each other to form a circle concentric with the main pipe 2. The gas supply pipes 3A, 3B, and 3C are integrally fixed to the peripheral surface of the main pipe 2 by fixing parts 3a, 3b, and 3c. The water supply pipe 4 is hollow and has the same length as the main pipe 2.

Description of Invention (12) Rotation angle of the actuator 6 8. As shown in FIG. 1, the propulsion device 40 has a rotation device 70, and the rotation device 70 has two independent passages. The compressor 72, which is placed on the ground, supplies air to the air supply pipes 3A, 3B, and 3C via a rotary device 70. The air supplied to the air supply pipes 3A '3B and 3C is further supplied to the air hammers 16A-16 of the front end hammer 10, and the air hammers 16A-16C are actuated. By controlling the opening and closing amount of the valves 73X-73Z of the air hammer 16A-16C, the air supply amount of each air supply pipe 3A, 3B and 3C can be adjusted. With this separate control method, the impact force of each air hammer 16A_16C can be adjusted separately, and the stop operation can be implemented separately. The valve 73X-73Z can be opened and closed by remote operation panel 104 or manual operation. The reference numeral 106 in Fig. 1 represents a laser theodolite, which is used to measure the amount of tilt of the front end hammer 10. The detailed measurement method will be described below. The laser theodolite 106 emits a laser to the target 63 on the shell rod 60. If the front end hammer 10 is excavated according to a predetermined plan, the laser beam will hit the center of the target 63. Therefore, by measuring the offset between the irradiation point and the center of the target 63, the offset of the front end hammer 10 relative to the predetermined route can be determined. If the laser beam deviates upward from the center point of the target device 63, it indicates that the front end hammer 10 deviates from a predetermined route downward. The state of the target device 63 measured by the positioning sensor is transmitted via a cable or radio wave, and its image is displayed on the screen of the operation panel 104. Operate the operation panel 104 while operating the circle, while watching the image on the screen, and make appropriate corrections. Reference numeral 108 in FIG. 1 represents a soil discharge device which discharges the soil collected by the soil discharge box 50 to the ground.

Next, the rod member 1 transmits the excavated soil along with the discharged air to the soil discharge box 50, and is discharged to the ground by the soil discharge device 108. Since the rod member 1 has the auger wing 5, no matter how long the excavation distance is, the excavated soil can be effectively discharged to the ground. Reference numeral 110 in Fig. 1 represents a hydraulic unit for driving the propulsion cylinder 48, and reference numeral 81 represents an inlet packer 81, which is used to inject sliding additives and prevent air from leaking out. The operation of the multi-air hammer device is described below. First, the drill bit 26 A-26C at the front end of the front hammer 10 is in contact with the working surface and drives the driving cylinder 48 of the propulsion device 40 to advance the front hammer 10 and the housing 12 °. When the driving cylinder 48 is driven, the rod rotation driver 68 is operated To turn the lever 1. Thereby, the rotation of the rod 1 is transmitted to the front end hammer 10, and the front end hammer 10 is rotated. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Further, when the rod member rotates the driver 68, it also drives the compressor 72 to open the valves 73X-73Z.

The air is then fed to the front hammer 10 to actuate the air hammers 16A-16C. More specifically, the hammer pistons 22A-22C of the air hammers 16A-16C are actuated and impact the drill bits 26A-26C; thereby, the drill bits 26A-26C repeatedly impact the working surface and crush the working surface. At this time, after contacting the working surface, the drill teeth 2 8A-28C on the drill 26A-26C are retracted from the front surface and expanded.

Description of the invention (14) 'Can dig diameter larger than the casing 1 2 of the digging hole 11 2. (Please read the precautions on the back before filling this page.) The soil excavated by the drill bits 26A-26C is discharged to the casing 12 through the space between the casing 12 and the hammer casing 18 by the exhaust effect. The excavated dirt discharged to the casing 12 is rotated by the rod 1 and transmitted to the dirt discharge box 50 with the discharged air, and then collected from the dirt discharge box 50 to the dirt discharge device 108. Under normal digging operations, the front end hammer 10 rotates in one direction, and each of the air hammers 16A-16C is actuated evenly for digging. (Refer to Figure (9)) The following describes the method for correcting the excavation direction when the front end hammer 10 deviates from the planned route. With the screen on the operation panel 104, you can confirm whether the front-end hammer 10 deviates from the planned route. Now suppose that the front end hammer 10 deviates from the planned route. First, temporarily stop the digging operation and use the screen to confirm the correct direction. Then, only the air hammer of the drill bit corresponding to the correct direction is actuated to impact the specific drill bit. In the example of Fig. 9 (b), only the air hammer 16A is actuated to hit the drill bit 26A. At this time, the driving lever rotates the driver 68 to rotate the front end hammer 10 back and forth within a predetermined angle range. As a result, as shown in FIG. 9 (b), only the ground surface located in the correct direction was hit by the drill bit 26A. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. When the above method is used to excavate the surface in the correct direction by a predetermined amount, all the air hammers 16A-16C are activated to impact the drill bits 26A-26C. At the same time, the rod rotation driver 68 rotates the front end hammer 10 in one direction, thereby using the drill bits 26A-26C to control the entire working surface. When the drill bits 26A-26C are actuated to excavate the surface by a predetermined amount, only the drill bit in the correct direction is actuated again, and the surface is excavated in the correct direction. And only the paper size of the drill bit corresponding to the correct direction is applied to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 480312 A7 B7 V. Invention Description (15) The air hammer rotates the front end hammer 10 back and forth within a predetermined angle range. As shown in Fig. 9 (c), by repeatedly performing partial digging and full digging in the correct direction, the direction of the front end hammer 10 is gradually corrected and the direction of the digging is corrected. At this time, because the impact surface of the drill bit is inclined, when the drill bit in the correct direction is actuated to impact the surface, a component force in the correct direction is generated, thereby improving the correction effect. By confirming the correction amount on the screen of the operation panel 104, it is possible to confirm the implementation of the control correction, and thereby complete the desired excavation work. After that, it returns to normal operation mode. As described above, the multi-air hammer device of this embodiment has high energy efficiency, and the driving direction can be easily corrected by driving and controlling the air hammers 16A-1 6C respectively. Can modify the digging direction 360 degrees. The multi-air hammer device of the present invention has retractable drill teeth 28A-28C. Therefore, by retracting the drill teeth 28A-28C, the front end hammer 10 can be pulled out into the vertical axis on the starting side, so what is the size of the vertical axis? Excavation can be implemented. Further, since the housing 12 is not required to be rotated during the excavation, there is no need to install a rotary driving device in the device, so that the device can obtain a smaller size. Even in the stable environment of the rock bed (where the casing 12 is unnecessary), the device can correct the excavation direction. In this embodiment, when the digging direction is corrected, the drill bit is rotated back and forth with respect to the hammer case 18 to dig the ground in the correct direction; however, digging can also be performed without rotation.

Description of the invention (16) (Please read the precautions on the back before filling out this page) When digging the direction, only the bit in the correct direction is activated; however, in this digging process, different impact forces are set on different bits, so each bit is used. More specifically, the impact force of the drill in the correct direction is greater than the impact force of the drill in other directions (that is, the actuation pressure of the gas hammer in the correct direction is higher than others), and the excavation caused by the different actuation pressure Differences to correct the digging direction. Further, in this embodiment, when the excavation direction is modified, only one drill bit is activated to perform the excavation; however, when needed, multiple drill bits may be used simultaneously. Next, an air hammer device according to a second embodiment of the present invention will be described below. As shown in FIG. 10, the rotating device 70 includes a rotating device body 76 and a rotating and rotating device 78. The rotating device body 76 mainly includes a casing 80 and a rotating body 84.

At this time, if the actuating air is supplied to only one air supply chamber 90A, the actuating air is supplied to the air hammer 16A only through the air supply passage 92A and the air supply pipe 3A, so only the air hammer 16A is activated. When the digging is controlled, the rod 1 rotates. When the lever member 1 is rotated, the rotating body 84 is also rotated, and at the same time, the air supply chambers 90A, 90B, and 90C are rotated. Here, the air is supplied to each of the air supply chambers 90A, 90B, and 90C only when each of the air supply chambers communicates with each of the air supply channels 86X, 86Y, and 86Z.

Now, suppose that the front end hammer 10 just shifts downward, as shown in Fig. 14 (a). At this time, one of the air supply channels 86X, 86Y '8 6Z is positioned in the correct direction. For example, turn the air supply channels 86X, 86Y ′ 86Z to the positions just facing up, as shown in Fig. 13 (a). If the supply channel 86X is in the correct direction, no operation is required. Next, 'the actuated air pressure Px supplied to the air supply channel 86X in the correct direction is higher than the air pressures Py, Pz supplied to the air supply channels 86Y and 86Z, and the applied air should be used for control and digging. When the high-pressure controlled digging air is supplied to the air supply channel 86X only in the manner described above, only the air hammer of the air supply chamber communicating with the air supply channel 86X is used to dig the ground. As the air hammer 16A_16C rotates, one of the air supply chambers 90A-90C communicating with the air supply passage 86X is continuously changed. With this, an air hammer 16A-16C that excavates the ground with a high impact force is switched, and the air hammer that just faces upwards controls the excavation with a high impact force. More specifically, mining is performed in the following manner. When the air supply chamber 90A communicates with the air supply channel 86X, as shown in FIG. 13 (a), the high-pressure actuating air is only supplied to 90A, and the air hammer 16A communicating with the air supply chamber 90A is higher than the air hammer 16B and The impact force of 16C impacts the drill bit 26A. As a result, the surface above was excavated with high impact. Since each air supply chamber 90A, 90B, 90C has a predetermined width, when the air supply chamber 90A communicates with the air supply channels 86X, 86Y, 86Z, even if the front end hammer 10 rotates, the high-pressure actuating air is only supplied to the air supply chamber. 90A, as shown in the figure.

Description of the invention (22) 13 (b). As a result, only the air hammer 16A-16C excavated the upper surface with a high impact force. (Please read the note on the back? Matters before filling out this page) Then, the front end hammer 10 rotates, and the air supply channel 86X is sealed by the outer periphery of the rotating body 84, as shown in FIG. 13 (c), so actuate The air supply will not be supplied to the air supply chambers 90A, 90B, 90C, and the operation of the air hammers 16A-16C will be stopped. The front hammer 10 is further rotated and the air supply chamber 90B is communicated with the air supply passage 86X, as shown in FIG. 13 (d), so the high-pressure actuating air is only supplied to the air supply chamber 90B. With this, only the air hammer 16B excavates the ground surface with a high impact force. At this time, the air hammer 16B is just in the upward direction, and the ground surface above is excavated only with a high impact force. As described above, when the upper surface is excavated only with a high impact force, the excavation of the front end hammer 10 is gradually corrected upward. The directions are as shown in Figs. 14 (a)-(d), and at least the center of the front end hammer 10 is positioned on the planning line, as shown in Fig. 14 (e). It is determined by the theodolite that P0 of the target 63 corresponds to the center point of the planned route, and it can be confirmed whether the center of the front end hammer 10 is located on the planned route. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs As mentioned above, when the center of the front-end hammer 10 is confirmed to be on the planned route, the correction operation is completed. In other words, as shown in FIG. 13 (e), the actuating air pressure supplied to each of the air supply channels 86X, 86Y, 86Z is made uniform (that is, Px = Py = Pz), and with a uniform impact force Actuating air is supplied to each of the air supply channels 86X, 86Y, 86Z for excavation. As described above, by simply supplying the actuating air, the plurality of air hammer devices in this embodiment can correct the digging direction, and the correction operation can be continuously performed. Therefore, the excavation direction can be effectively corrected. The paper size of the multi-air hammer device of this embodiment is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 480312 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention (23) The special double tube structure can reduce the size of the entire device. In this embodiment, an example has been described in which the excavation direction is corrected upward. If the excavation direction is corrected to the left of the theodolite, the air supply channel 86X opens to the left. At this time, the motor 94 of the rotary device 78 is driven to rotate the housing 80 of the rotary device body 76 so that the air supply passage 86X is turned to the left. Next, the air pressure Px of the actuated air supplied to the air supply passage 86X is made higher than the air pressures Py, Pz of the actuated air supply passages 86Y, 86Z, and the actuated air is supplied to the air supply passages 86X, 86Y, 86Z. Thereby, the ground surface on the left side is hit with a high impact force, so that the digging direction of the front end hammer 10 is corrected to the left side. Similarly, if the excavation direction is corrected to the right of the theodolite, the air supply channel 86X turns to the right, and the air pressure Px supplied to the air supply channel 86X is higher than the air pressures Py, Pz supplied to the air supply channels 86Y, 86Z, and Actuating air is supplied to the air supply channels 86X, 86Y, 86Z, respectively. As described above, by turning one of the air passages in the correction direction and making the air pressure supplied to one air passage higher than the air pressure supplied to the other air supply passages, the air pressure can be corrected 360 degrees in either direction. . Further, the intermediate point of the two air supply channels can be turned to the corrected direction, and the actuating pressure supplied to the two air channels can be set higher. For example, the intermediate points of the air supply channels 86X and 86Y are turned to the correct direction, and the actuation pressure supplied to the air supply channels 86X and 86Y is set higher than the actuation pressure supplied to the air channel 86Z. Next, the actuating air pressure is supplied to the individual air supply channels 86X, 86Y, 86Z. As a result, the two air hammers connected to the gas supply channels 86X and 86Y control the surface of the excavation in a corrected direction with a higher impact force, and modify the excavation direction.

Description of Invention (24) Now, other methods of correcting the direction of excavation will be described. First, turn one of the air supply channels 86X, 86Y, and 86Z to the correction direction (such as the upward direction). At this time, as shown in Fig. 13 (a), the air supply passage 86X is placed in an upward direction. Then, only the actuating air is supplied to the air supply passage 86X which has been corrected to the correct direction. At this time, the propelling cylinder 48 and the rod rotation driver 68 are driven to rotate the front end hammer 10. At this time, since the actuating air is only supplied to the air supply passage 86X, the actuating air is only supplied to the air supply chambers 90A, 90B, and 90C communicating with the air supply passage 86X. Further, as shown in FIG. 13 (a), when the air supply channel 86X communicates with the air supply chamber 90A, the actuating air is only supplied to the air supply chamber 90A; as a result, only the air hammer 16A is activated, and only the drill bit is used. 26A digs the ground directly above. Because the air supply chambers 90A, 90B, 90C have a predetermined width, even if the front end hammer 10 rotates, when the air supply chamber 90A communicates with the air supply passage 86X, the actuating air is only supplied to the air supply chamber 90A, as shown in FIG. 13 (b). Shown, so only the air hammer 16A is activated. Next, the front hammer 10 rotates, and the air supply passage 86X is sealed by the outer periphery of the rotating body 84, as shown in FIG. 13 (c), so the actuating air will not be supplied to the air supply chambers 90A, 90B, 90C. As a result, All air hammers 16A-16C are stopped. Thereafter, the front end hammer 10 is further rotated, and the air supply passage 86X communicates with the air supply chamber 90B, as shown in Fig. 13 (d). At this time, the actuating air is supplied only to the air supply chamber 90B, and only the air hammer 16B is actuated. At this moment, the air hammer 16B is just in the upward direction, and only the drill head 26B is used to dig the ground upward. -27 ^ (Please read the precautions on the back before filling in this page) ·· --- Order ---- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) 480312 A7 B7 V. Description of the Invention (25) (Please read the precautions on the back before filling in this page) As mentioned above, because the air supply chambers 90A, 90B, 90C have a predetermined width, even if the front end hammer 10 rotates, when the air supply chamber 90B communicates with the air supply In the passage 86X, the actuating air is only supplied to the air supply chamber 90B, as shown in FIG. 13 (e), so only the air hammer 16B is actuated. As described above, when only the air is supplied to the upward air supply passage 86X, even if the front hammer 10 is rotated, only the upward air hammer is actuated, and therefore only the upward surface is dug. In the correction direction, after digging the surface by a predetermined amount, all the air hammers 16A-16C are actuated to dig the surface with all the bits 26A-26C. At this time, since the ground surface in the correct direction is excavated in advance, the front end hammer 10 is gradually advanced toward the correction direction, so that the excavation direction can be corrected. If the correction operation cannot be used to achieve the desired correction, the above-mentioned operation is performed quickly. After obtaining the correct amount of correction, it returns to the normal digging operation. After the excavation direction is corrected in the manner described above, the device of this embodiment can be easily corrected by simply changing the amount of air. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs In the present invention, three kinds of gas supply channels 86X, 86Y, 86Z are formed in the casing 80 of the rotating device body 76, however, the number of gas supply channels is not limited to three. For example, it is possible to form four air supply channels that are 90 degrees apart, or six air supply channels that are 60 degrees apart. Further, in this embodiment, the rotating device of the present invention can be applied to other excavation equipment that does not use an air hammer. The excavating equipment of the present invention can also be applied to other equipment using fluid instead of air.
