Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic drills, and particularly relates to a roadheader-mounted hydraulic drill. Background Technique

[0002] The roadheader-mounted hydraulic drill usually drills the rock wall of the coal mining roadway to facilitate the installation of support equipment in the later stage, or drills the required ground. When drilling the ground, the drilling depth is usually large. Generally, the initial drill pipe is first drilled. After drilling, the drill pipe and the motor are separated and another drill pipe is connected. Then, the other drill pipe is connected to the motor for drilling. Through the continuous splicing of multiple drill pipes, the deep drilling work of the ground can be carried out. For roadway drilling, thick drill pipes or the same thin drill pipes as those for ground drilling can be used according to needs for the drilling work.

[0003] However, in the traditional roadheader-mounted hydraulic drill, one end of the drill pipe is usually connected to the output shaft of the motor, and then the other end is used for drilling work. There is no limitation on the drill pipe that has not penetrated into the rock. It is easy to cause the drill pipe outside to shake, affecting the service life and the drilling accuracy. At the same time, when the drilling work on the ground is completed and the drilled drill pipe needs to be pulled out, the drill pipe connected to the motor needs to be pulled out, causing several drill pipes inside the drill hole to be pulled up as a whole. After being pulled up to a certain height, the drill pipe connected to the motor is separated and then removed. The motor moves down and is connected to the next drill pipe, and then the work of pulling out and removing the drill pipe is carried out again. Repeating the above operations until the drill pipe is removed. However, there is no limit on the drill pipe during the process. When separating the drill pipe, it is easy for the drill pipe still inside the drill hole to fall due to the loss of the connection relationship between the drill pipe inside the drill hole and the removed drill pipe. Therefore, the present invention proposes a roadheader-mounted hydraulic drill. Summary of the Invention

[0040] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0041] As Figures 1 - 13 shown, a hydraulic drill mounted on a roadheader includes a body part 1. A support plate 2 is fixedly arranged at the top of the body part 1. A movable frame 3 is rotatably connected to the support plate 2, and one end of the movable frame 3 penetrates through the support plate 2 and is fixedly connected to the output shaft of a first motor 4. A storage rack 5 is slidably connected to the movable frame 3. A storage plate 6 is slidably arranged inside the storage rack 5. A second motor 7 is arranged on one side of the storage plate 6. Both ends of the storage rack 5 are respectively fixedly connected to a first fixing frame 8 and a hollow plate 10. A multi-stage electric telescopic rod 9 is arranged inside the first fixing frame 8. One end of the multi-stage electric telescopic rod 9 is fixedly connected to the storage plate 6. A limiting structure 11 is arranged on the top of the hollow plate 10;

[0042] The limiting structure 11 includes three groups of first limiting components. Each first limiting component includes a first fixing plate 14, three first movable rods 15, a first triangular block 16 and a first bottom plate 17. The first fixing plate 14 is fixedly connected to the hollow plate 10. The first fixing plate 14 and the first movable rods 15 are connected through holes. The first triangular block 16 and the first bottom plate 17 are both fixedly connected to the first movable rods 15. A first baffle 18 is fixedly connected to the top of the first triangular block 16. Three clamping sleeves 19 are fixedly arranged on one side of the first bottom plate 17. A ball 20 is arranged inside each clamping sleeve 19. Three first springs 21 are arranged between the first fixing plate 14 and the first triangular block 16.

[0043] The limiting structure 11 and the first limiting components cooperate with each other, can limit according to the size of the drill pipe, and play an auxiliary positioning role for the drill pipe at the same time. It can make the drill pipe stable during the drilling work and avoid large-amplitude shaking. At the same time, the setting of the balls 20 makes the balls 20 not generate large resistance friction to the rotation and up-and-down movement of the drill pipe.

[0044] In this embodiment, the limiting structure 11 further includes three groups of second limiting components. Each second limiting component includes a second fixing plate 22, three second movable rods 23, a second triangular block 24 and a limiting plate 25. The second fixing plate 22 is fixedly connected to the hollow plate 10. The second movable rods 23 and the second fixing plate 22 are connected through holes. The second triangular block 24 and the limiting plate 25 are both fixedly connected to the second movable rods 23. Three second springs 26 are arranged between the second fixing plate 22 and the second triangular block 24.

[0045] The cooperation between the second limiting components and the limiting structure 11 is beneficial to the work of increasing or decreasing the number of drill pipes during deep drilling of the ground. It can ensure that the drill pipes still in the drill hole are clamped and fixed after the drill pipes connected to the second motor 7 are removed, and avoid the drill pipes in the drill hole falling due to the loss of the connection relationship, enhancing the work safety.

[0046] In this embodiment, the limiting structure 11 further includes a first transmission assembly. The first transmission assembly includes a second fixing frame 27. The second fixing frame 27 is fixedly connected to the hollow plate 10. An electric push rod 28 is arranged inside the second fixing frame 27. One end of the electric push rod 28 is fixedly connected to a first fixing frame 29. Three fixing rods 30 are fixedly arranged inside the first fixing frame 29.

[0047] The first transmission assembly cooperates with the limiting structure 11 to enable the first limiting assembly to reduce its range, and then the ball 20 can be brought into contact with the drill rod, ensuring that the first limiting assembly can stably support the drill rod and prevent large-amplitude shaking. The setting of the first spring 21 can cause the ball 20 to return to its initial position by rebounding when the first transmission assembly does not act on the first limiting assembly, releasing the limiting effect on the drill rod.

[0048] In this embodiment, the limiting structure 11 further includes a second transmission assembly. The second transmission assembly includes a first fixing block 31. The first fixing block 31 is fixedly connected to the hollow plate 10. An electric push rod 32 is arranged on the top of the first fixing block 31. One end of the electric push rod 32 is fixedly connected to a connecting plate 33. The connecting plate 33 is fixedly connected to a second fixing frame 34. Three third fixing frames 35 are fixedly arranged at the bottom of the second fixing frame 34. An activity roller 36 is rotatably arranged inside the third fixing frame 35.

[0049] The second transmission assembly cooperates with the limiting structure 11 to enable the second limiting assembly to stably clamp the drill rod and prevent the drill rod from falling. At the same time, when the transmission assembly does not act on the second limiting assembly, the second spring 26 can rebound the limiting plate 25 to its initial position to release the clamping restriction on the drill rod.

[0050] In this embodiment, a second bottom plate 37 is fixedly connected to the outside of the movable frame 3. Two multi-stage electric telescopic rods 38 are arranged on the top of the second bottom plate 37. A second baffle 39 is fixedly connected to the outside of the storage rack 5. One end of the multi-stage electric telescopic rod 38 is fixedly connected to the second baffle 39.

[0051] The multi-stage electric telescopic rod 38 cooperates with the storage rack 5 through the second baffle 39 to enable the storage rack 5 to slide inside the movable frame 3, which is beneficial to adjusting the position of the storage rack 5.

[0052] In this embodiment, the positions of the fixing rods 30 and the first triangular block 16 are adaptively matched. The first spring 21 is located around the corresponding first movable rod 15. The positions of the activity rollers 36 and the second triangular block 24 are adaptively matched. The second spring 26 is located around the corresponding second movable rod 23.

[0053] The first spring 21 and the second spring 26 respectively play an elastic support role for the ball 20 and the limiting plate 25.

[0054] In this embodiment, a support adjustment structure 12 is arranged outside the storage rack 5. The support adjustment structure 12 includes two chute plates 40. A slider 41 is slidably arranged outside the chute plate 40. A fixed frame three 42 is fixedly arranged on one side of the slider 41. A motor three 43 is arranged between the fixed frame three 42 and the slider 41. The output shaft of the motor three 43 penetrates through the fixed frame three 42 and is fixedly connected with a fixed sleeve 44. A multi-stage electric telescopic rod three 45 is fixedly arranged inside the fixed sleeve 44.

[0055] The support adjustment structure 12 cooperates with the storage rack 5, which is beneficial to adjust the multi-stage electric telescopic rod three 45 at multiple angles, facilitating the auxiliary support for the storage rack 5 at one end with the hollow plate 10. It can solve the defect that the storage rack 5 lacks support away from the movable rack 3. At the same time, cooperating with the limiting structure 11 can better provide stable working conditions for the drilling of the drill pipe and prevent the storage rack 5 from shaking greatly during the drilling of the drill pipe, which affects the accuracy.

[0056] In this embodiment, a transmission component three is arranged outside the fixed frame three 42. The transmission component three includes a convex block 46. The convex block 46 is fixedly connected with the fixed frame three 42. A motor four 47 is arranged on one side of the convex block 46. The output shaft of the motor four 47 penetrates through one side of the convex block 46 and is fixedly connected with a gear roller 48. The gear roller 48 is meshed with a sawtooth plate 49. The sawtooth plate 49 is fixedly connected with the storage rack 5.

[0057] The transmission component three cooperating with the support adjustment structure 12 is beneficial to adjust the position of the multi-stage electric telescopic rod three 45. The position of the multi-stage electric telescopic rod three 45 outside the storage rack 5 can be adjusted according to needs, and the storage rack 5 can be better supported according to needs.

[0058] In this embodiment, two groups of auxiliary structures 13 are arranged on the top of the machine body part 1. The auxiliary structures 13 include a limit groove plate 50 and a fixed block two 51. Both the limit groove plate 50 and the fixed block two 51 are fixedly connected with the machine body part 1. The fixed block two 51 is threadedly connected with a threaded rod 52. One end of the threaded rod 52 is rotatably connected with a clamping block 53.

[0059] The auxiliary structure 13 cooperating with the support adjustment structure 12 is beneficial to the storage after the hydraulic drill works, fixes one end of the multi-stage electric telescopic rod three 45 on the top of the machine body part 1, and supports the storage rack 5 through the multi-stage electric telescopic rod three 45, which can ensure stability.

[0060] In this embodiment, one end of the multi-stage electric telescopic rod three 45 is adaptively matched with the limit groove of the limit groove plate 50.

[0061] One end of the multi-stage electric telescopic rod three 45 is clamped into the limit groove of the limit groove plate 50.

[0062] It should be noted that the present invention is an on - vehicle hydraulic drill for a tunneling machine. Before use, place the hydraulic drill in the required location to make it meet the operating conditions. According to the usage requirements, the hydraulic drill can be used in two usage scenarios. In addition, Figure 1 、 Figure 12 and Figure 13 are the initial state diagrams for the first usage scenario to drill the ground;

[0063] Usage Scenario One: When it is necessary to drill deeply into the ground, in the Figure 1 initial state, fix one end of the initial drill pipe to the output shaft of the second motor 7 and then start the second motor 7 to make the initial drill pipe rotate. Start the multi - stage electric telescopic rod one 9 to make the placement plate 6 slide towards the ground inside the placement rack 5. During this process, one end of the initial drill pipe passes through the hollow plate 10 and drills into the ground for drilling work. Start the electric push rod one 28 to act on the first fixed frame 29 to drive the three fixed rods 30 to move in the opposite direction of the ground. While the fixed rods 30 move upward, they act on the first triangular block 16 to move towards the first fixing plate 14. The first triangular block 16 acts on the bushing 19 and the ball 20 to move synchronously through the first movable rod 15 until the ball 20 touches the surface of the initial drill pipe and then stops. At this time, several balls 20 play a role in limiting and supporting the drill pipe, preventing the drill pipe from shaking significantly and affecting the accuracy;

[0064] When the placement plate 6 moves down to the predetermined position, most of the initial drill pipe has drilled into the ground. At this time, stop the operation of the second motor 7. Start the electric push rod two 32 to act on the connecting plate 33 to drive the second fixed frame 34 to move towards the ground. The second fixed frame 34 acts on the third fixed frame 35 and the movable roller 36 to move synchronously. The movable roller 36 acts on the second triangular block 24 to move towards the second fixing plate 22. The second triangular block 24 acts on the limiting plate 25 to move synchronously through the second movable rod 23 until the limiting plate 25 touches the surface of the initial drill pipe and then stops. At this time, the limiting plate 25 clamps and fixes the initial drill pipe. Then separate the initial drill pipe from the output shaft of the second motor 7. Start the multi - stage electric telescopic rod one 9 to make the second motor 7 and the placement plate 6 return to the initial position. Connect the two ends of the next drill pipe to the output shaft of the second motor 7 and one end of the initial drill pipe respectively. Then, through the electric push rod two 32, make the movable roller 36 return to the initial position. Under the action of the second spring 26, the limiting plate 25 rebounds to the initial position to release the clamping restriction on the initial drill pipe. Start the second motor 7 and the multi - stage electric telescopic rod one 9 to continue the drilling work on the initial drill pipe and the just - connected next drill pipe. According to the need of the drilling depth, repeat the above operation to increase the number of drill pipes;

[0065] After the ground drilling is completed, stop the rotation of the second motor 7. Pull back the second motor 7 to its initial position through the multi-stage electric telescopic rod 9. At this time, several drill pipes drilled into the ground are all pulled up. Use the electric push rod 32 to make the limit plate 25 clamp and fix the corresponding drill pipe. Remove the drill pipe connected to the second motor 7. Then, move the second motor 7 downward to the next drill pipe through the multi-stage electric telescopic rod 9 and connect it. Move the fixing frame 34 to its initial position through the electric push rod 32. Under the action of the second spring 26, the limit plate 25 releases the restriction on the drill pipe. Then, pull back the second motor 7 to its initial position through the multi-stage electric telescopic rod 9. Then, use the electric push rod 32 to make the limit plate 25 clamp the drill pipe. Then, remove the drill pipe connected to the second motor 7. Repeat the above operations to remove the drill pipe;

[0066] When the drilling work is completed and the drill pipes are removed, rotate the threaded rod 52 to make the clamping block 53 move towards the second fixed block 51 until the clamping block 53 releases the restriction above the limit groove plate 50 and then stop. Start the first motor 4 to make the movable frame 3 drive the storage rack 5 to rotate 90 degrees in the opposite direction of the ground and then stop. At this time, the storage rack 5 is parallel to the ground. Start the multi-stage electric telescopic rod 38 to act on the second baffle 39. The second baffle 39 drives the storage rack 5 to move in the opposite direction of the support plate 2 to a predetermined position and then stop. Start the third motor 43 to make the fixed sleeve 44 drive the multi-stage electric telescopic rod 45 to rotate 90 degrees in the direction of the ground and then stop. Start the multi-stage electric telescopic rod 45 to make one end of it move towards the top of the machine body 1 until it contacts the top of the machine body 1 and then stop. Then, start the fourth motor 47 to act on the gear roller 48 to rotate. The gear roller 48 meshes with the serrated plate 49 to make the slider 41 slide outside the chute plate 40 in the direction of the second motor 7 until one end of the multi-stage electric telescopic rod 45 is clamped into the limit groove plate 50 and then stop. Rotate the threaded rod 52 to make the clamping block 53 move to limit one end of the multi-stage electric telescopic rod 45 and then stop. At this time, the multi-stage electric telescopic rod 45 cooperates with the support plate 2 to support the storage rack 5 and share the pressure on the support plate 2;

[0067] Usage Scenario 2: When it is necessary to drill the rock wall of the roadway, at Figure 1In the initial state, start motor 1 - 4 so that the movable frame 3 drives the storage rack 5 to rotate 90 degrees in the direction opposite to the ground and then stop. At this time, the storage rack 5 is parallel to the ground. Start motor 3 - 43 so that the fixed sleeve 44 drives the multi - stage electric telescopic rod 3 - 45 to rotate 90 degrees in the direction of the ground and then stop. Start the multi - stage electric telescopic rod 3 - 45 to move one end towards the ground until it touches the ground and then stop. At this time, the two ends of the storage rack 5 are supported by the multi - stage electric telescopic rod 3 - 45 and the support plate 2 respectively, avoiding the lack of support force at the end of the storage rack 5 with the hollow plate 10, which may cause large - amplitude shaking during drilling and affect the accuracy. At this time, install the drill pipe on the output shaft of motor 2 - 7 and drill the rock wall using the same operation principle as in Scenario 1. The removal of the drill pipe after drilling and the storage of the storage rack 5 are the same as the operation principle in Scenario 1;

[0068] In addition, drill pipes of different thicknesses can be installed according to needs for drilling work. At the same time, the movable frame 3 and the fixed sleeve 44 are not limited to rotating 90 degrees. The movable frame 3 and the fixed sleeve 44 can be adjusted by motor 1 - 4 and motor 3 - 43 respectively according to the drilling angle.
