Description

Technical Field

[0001] The present invention relates to the technical field of drilling, and specifically to an isolated drilling device based on parallel propulsion and its application in construction. Background Art

[0002] During the construction of projects such as bridges, tunnels, and slopes, it is necessary to drill holes on the side to facilitate the subsequent installation of devices such as signboards. In the above construction projects, there are situations where hole drilling operations need to be carried out in some relatively narrow areas. At this time, if the operator enters this area for operation, the operation difficulty will increase due to limited space. At the same time, in the curved areas of bridges, tunnels, and slopes, the installation of signboards is more important.

[0003] Due to being in a curved area, the road edge protrusions on its side are in a spiral inclined state. In order to improve the installation effect of the signboard, therefore, construction workers need to adjust the angle of the electric drill. The adjusted angles include up-and-down adjustment and left-and-right adjustment. However, due to the construction location problems, construction workers are affected by factors such as limited space, the working surface being a suspended position, and inconvenient power transmission when adjusting, and they cannot quickly adjust the angle of the electric drill, resulting in great operation difficulty and affecting the subsequent installation accuracy and indication effect of the signboard.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, which can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0042] Please refer to Figures 1 to 11 , in the embodiment of the present invention, a parallel propulsion isolation type drilling device includes: a frame structure 1, a pulling assembly, a follower plate 13, a rotating assembly and an adjusting assembly.

[0043] The adjusting assembly is installed on the frame structure 1 and is connected to the pulling assembly and the rotating assembly. The adjusting assembly includes a threaded adjusting structure and an operating rod 6. A locking tongue 601 provided on the operating rod 6 cooperates with two groups of locking grooves 19 provided on the threaded adjusting structure, and can respectively control the actions of the pulling assembly and the rotating assembly.

[0044] The threaded adjusting structure includes two groups of coaxial hollow threaded rods 8 rotatably installed on the frame structure 1. The locking grooves 19 are provided at the opposite ends of the two groups of hollow threaded rods 8. The operating rod 6 passes through the hollow threaded rods 8. Specifically, two groups of inclined surfaces are provided at one end of the locking groove 19 facing its opening, and the inclined surfaces on the opposite sides of the adjacent two groups of locking grooves 19 intersect, that is, the two groups of inclined surfaces form a spiked portion, and one end of the locking tongue 601 facing the locking groove 19 is also provided with a spiked portion, so that when the locking tongue 601 is inserted into the locking groove 19, the inclined surface can guide the locking tongue 601 into the locking groove 19, so that the locking tongue 601 can be inserted into the corresponding locking groove 19 by inserting and pulling the operating rod 6. When the operating rod 6 is rotated, the two groups of hollow threaded rods 8 can be respectively driven to rotate, thereby driving the pulling assembly and the rotating assembly to act, and realizing the step-by-step control of the pulling assembly and the rotating assembly.

[0045] It should be noted that the operating rod 6 and the frame structure 1 can slide and rotate relative to each other, and a damping sleeve is provided at the connection between the operating rod 6 and the frame structure 1 to improve the stability of the operating rod 6 after the operating rod 6 is inserted and pulled out. At the same time, the inner wall diameter of the two hollow threaded rods 8 is larger than the outer wall diameter of the operating rod 6 to prevent the hollow threaded rod 8 from rotating when the tongue 601 is not engaged with the locking groove 19 during the process of controlling the rotation of the operating rod 6 due to the friction between the operating rod 6 and the inner wall of the hollow threaded rod 8.

[0046] The thread adjustment structure further includes a first threaded sleeve 5 and a second threaded sleeve 9 that are threadedly engaged with the two hollow threaded rods 8. The first threaded sleeve 5 is connected to the pulling assembly, and the second threaded sleeve 9 is connected to the rotating assembly. Additionally, in this embodiment, to improve the movement stability of the second threaded sleeve 9, a guiding member can be provided on the frame structure 1. The guiding member maintains the axial stability of the second threaded sleeve 9 by slidingly connecting with the second threaded sleeve 9 to prevent the second threaded sleeve 9 from rotating along with the hollow threaded rod 8.

[0047] By inserting and pulling out the operating rod 6, the tongue 601 can be inserted into the corresponding locking groove 19, so that when the operating rod 6 is rotated, the two hollow threaded rods 8 can rotate respectively. When one of the hollow threaded rods 8 rotates, the first threaded sleeve 5 that is threadedly engaged with it can move along the length direction of the hollow threaded rod 8, thereby driving the pulling assembly to act, and realizing the adjustment of the pitching angle of the receiving plate 2. When the other hollow threaded rod 8 rotates, the second threaded sleeve 9 that is threadedly engaged with it can move along the length direction of the hollow threaded rod 8, thereby driving the rotating assembly to act, and changing the deflection angle of the follower plate 13. Based on the above settings, during the process of inserting and pulling out the operating rod 6 and rotating the operating rod 6, the two hollow threaded rods 8 can be respectively driven to rotate, so as to separately control the pulling assembly and the rotating assembly. Moreover, the hollow threaded rod 8 and the first threaded sleeve 5 and the second threaded sleeve 9 are connected by threads, and the threaded connection has self-locking property, so that when the tongue 601 is separated from one of the hollow threaded rods 8, the first threaded sleeve 5 or the second threaded sleeve 9 connected to it can maintain the locked state, thereby enabling the pitching angle of the receiving plate 2 and the deflection angle of the follower plate 13 to have better stability after the adjustment is completed, and improving the drilling quality.

[0048] Please refer to Figures 5 to 6 , a receiving plate 2 is rotatably installed on the frame structure 1. Among them, the frame structure 1 is composed of two parallel plates and a connecting plate perpendicular to the parallel plates. One end of the connecting plate far from the parallel plates is rotatably connected to the receiving plate 2;

[0049] Furthermore, two sets of connecting plates are provided at one end of the parallel plate away from the connecting plate. A U-shaped structure is formed between the two sets of connecting plates and the parallel plate. A plurality of roller wheels are rotatably installed inside the U-shaped structure. During use, the U-shaped structure is clamped on the edge protrusions of bridges, tunnels, and slopes, so that the roller wheels are in contact with the edge protrusions, thereby improving the stability of the frame structure 1 during the drilling state. At the same time, after the drilling is completed, the frame structure 1 can be pulled to move along the length direction of the edge protrusion, thereby reducing the difficulty of moving the frame structure 1.

[0050] It should be noted that considering the different inner angles and widths of the edge protrusions of bridges, tunnels, and slopes, the connecting plate away from the connecting plate can also be set to be detachably connected to the parallel plate, so as to match different types of bridges, tunnels, or slopes.

[0051] The pulling component is slidably arranged on the frame structure 1. When the pulling component moves along the length direction of the frame structure 1, the pitching angle of the receiving plate 2 can be changed;

[0052] The pulling component includes a sliding connector 4 slidably installed on the frame structure 1 and connected to the first threaded sleeve 5. An elevating rod 3 capable of moving in the vertical direction is slidably installed on the sliding connector 4. Among them, the sliding connector 4 can slide along the length direction of the parallel plate, and the elevating rod 3 can slide perpendicular to the parallel plate relative to the sliding connector 4, that is, the elevating rod 3 can vertically lift relative to the parallel plate.

[0053] A fitting shaft 302 is rotatably installed on the elevating rod 3, and the fitting shaft 302 is in rolling connection with a fitting groove 202 provided on the side of the receiving plate 2.

[0054] In the initial state, the fitting shaft 302 is located in the middle of the fitting groove 202. At this time, the receiving plate 2 is in a state parallel to the parallel plate. When the sliding connector 4 slides and the elevating rod 3 lifts relative to the parallel plate, the elevating rod 3 can perform horizontal translation and vertical movement. During this process, the fitting shaft 302 can move toward both ends along the length direction of the fitting groove 202. At the same time, the cooperation between the fitting shaft 302 and the fitting groove 202 can pull the receiving plate 2 to move when the elevating rod 3 moves vertically, so that the receiving plate 2 can deflect around its rotation center, thereby changing the pitching angle of the receiving plate 2. Among them, the pitching angle range of the receiving plate 2 is -10° to 10°.

[0055] The pulling component further includes a guiding structure disposed on the lifting rod 3 and the frame structure 1. The guiding structure can drive the lifting rod 3 to change its height relative to the frame structure 1. The guiding structure includes a convex shaft 301 rotatably mounted on the lifting rod 3 and a side plate 7 fixedly mounted on the frame structure 1. An inclined groove 701 is provided on the side plate 7, and the convex shaft 301 can roll within the side plate 7;

[0056] The follower plate 13 is parallel to the receiving plate 2, and a drill 16 capable of moving along its length direction is provided on the follower plate 13.

[0057] Specifically, when the first threaded sleeve 5 drives the sliding connector 4 to move, the sliding connector 4 can drive the lifting rod 3 to move perpendicular to the parallel plate. In the initial state, the convex shaft 301 is located at the middle position of the inclined groove 701. When the lifting rod 3 moves along the length direction of the parallel plate, the convex shaft 301 can move along the inclined groove 701. At this time, the lifting rod 3 can move along the direction perpendicular to the length direction of the parallel plate while moving along the length direction of the parallel plate. Through the cooperation of the fitting shaft 302 and the fitting groove 202, the lifting and lowering of the receiving plate 2 are realized to change the pitching angle of the receiving plate 2. Since the follower plate 13 is parallel to the receiving plate 2, the pitching angle of the drill 16 connected to the follower plate 13 will also change accordingly, so as to change the pitching angle of the drill 16. When constructing on the curb protrusions in the curved areas of bridges, tunnels, and slopes, the construction angle of the drill 16 is ensured, and it is ensured that after drilling, the corresponding equipment is easier to install.

[0058] Please refer to Figure 3 、 Figures 7 to 9 The rotating component is disposed on the frame structure 1 and connected to the follower plate 13. The rotating component can change the deflection angle of the follower plate 13;

[0059] The rotating assembly includes a rotating rod 12 rotatably connected to the frame structure 1. The lower end of the rotating rod 12 is connected to the follower plate 13. Wherein, when the projection of the length direction of the follower plate 13 on the horizontal plane is parallel to the projection of the length direction of the parallel plate on the horizontal plane, the rotation axis of the follower plate 13 is coaxial with the rotation axis of the receiving plate 2. At this time, when the rotating rod 12 rotates to change the pitching angle, the follower plate 13 can rotate synchronously without interference. It should be emphasized that when adjusting the pitching angle of the receiving plate 2 and the deflection angle of the follower plate 13, the pitching angle of the receiving plate 2 should be adjusted first and then the deflection angle of the follower plate 13. And in the initial state, the follower plate 13 is parallel to the length direction of the parallel plate. At this time, the rotation axis of the follower plate 13 is coaxial with the rotation axis of the receiving plate 2, so that when the pitching angle of the receiving plate 2 changes, the pitching angle of the follower plate 13 changes. Then, the deflection angle of the follower plate 13 is adjusted to prevent the adjustment of the pitching angle of the receiving plate 2 from being blocked due to the non-coaxial rotation axes of the follower plate 13 and the receiving plate 2 after the deflection angle of the follower plate 13 changes.

[0060] A lifting sleeve 11 is slidably sleeved on the rotating rod 12. A hinge rod 10 is rotatably installed on the lifting sleeve 11. One end of the hinge rod 10 away from the lifting sleeve 11 is connected to the second threaded sleeve 9. It should also be noted that by providing a guiding member, the second threaded sleeve 9 can be prevented from rotating with the hollow threaded rod 8, resulting in the hinge rod 10 bearing torque. However, when the lifting sleeve 11 moves and tends to rotate the rotating rod 12, the lifting sleeve 11 will also have a tendency to rotate. Therefore, a guiding member can be provided on the frame structure 1 to limit the rotation of the lifting sleeve 11 by slidably connecting the guiding member to the lifting sleeve 11. On the one hand, the correlation between the lifting distance of the lifting sleeve 11 and the rotation angle of the rotating rod 12 can be improved, and on the other hand, the control accuracy can be improved.

[0061] The rotating assembly further includes a keyway kit disposed between the lifting sleeve 11 and the rotating rod 12. The keyway kit can drive the rotating rod 12 to rotate when the lifting sleeve 11 performs a lifting action. The keyway kit includes a guiding shaft 1101 disposed on the inner wall of the lifting sleeve 11 and a spiral groove 1201 disposed on the circumferential side wall of the rotating rod 12. The guiding shaft 1101 is slidably engaged with the spiral groove 1201.

[0062] In the initial state, the guiding shaft 1101 is at the middle position of the spiral groove 1201. When the second threaded sleeve 9 moves along the length direction of the hollow threaded rod 8 when the hollow threaded rod 8 it is threadedly connected to rotates, the second threaded sleeve 9 can drive the lifting sleeve 11 to move along the length direction of the rotating rod 12 through the hinge rod 10, and drive the rotating rod 12 to rotate by using the cooperation between the guiding shaft 1101 and the spiral groove 1201. At this time, the rotating rod 12 can drive the follower plate 13 to deflect, thereby changing the deflection angle of the electric drill 16. In this state, since both the pitching angle and the deflection angle of the electric drill 16 are controlled, the position accuracy during drilling is improved.

[0063] Through the above settings, the pitching angle and the tilting angle of the electric drill 16 can be adjusted separately, and at the same time, the stability of the tilting angle is ensured when adjusting the pitching angle of the electric drill 16, and the stability of the pitching angle is ensured when adjusting the tilting angle of the electric drill 16, so that the orientation of the electric drill 16 has stability in a controllable state. On the one hand, the adjustment difficulty can be reduced, on the other hand, the drilling accuracy can be improved, and the complexity during the subsequent equipment installation can be reduced.

[0064] Please refer to Figure 1 、 Figure 6 、 Figure 8 、 Figure 11 . Two sets of grooved pulleys 14 are rotatably installed on the follower plate 13, and the grooved pulleys 14 can roll in the arc-shaped grooves 201 provided on the receiving plate 2. Among them, taking the length direction of the receiving plate 2 as the reference plane, the included angle of both ends of the arc-shaped groove 201 relative to this reference plane is -8° to 8°, that is, the adjustable range of the deflection angle of the follower plate 13 is -8° to 8°.

[0065] During use, the grooved pulleys 14 can roll in the arc-shaped grooves 201, so that with the cooperation between the grooved pulleys 14 and the arc-shaped grooves 201, the receiving plate 2 has a pulling effect on the follower plate 13, thereby ensuring the stable parallel state of the follower plate 13 and the receiving plate 2, and improving the stability of the electric drill 16 when moving relative to the follower plate 13.

[0066] A sliding groove 1301 is further provided on the follower plate 13 along its length direction. A slider 1501 is slidably installed in the sliding groove 1301, and a moving frame 15 connected to the slider 1501 is connected to the electric drill 16;

[0067] A pulling frame 18 is slidably installed on the frame structure 1. Specifically, the pulling frame 18 is slidably arranged through the frame structure 1. A connecting groove 1801 is provided on the pulling frame 18, and the connecting groove 1801 cooperates with a connecting shaft 17 rotatably installed on the follower plate 13, and can drive the electric drill 16 to move when the pulling frame 18 acts.

[0068] It should also be noted that the width of the connecting groove 1801 is greater than the diameter of the connecting shaft 17. The purpose is that if the width of the connecting groove 1801 is equivalent to the diameter of the connecting shaft 17, interference will occur between the connecting groove 1801 and the connecting shaft 17 when the connecting shaft 17 follows the pitch angle and deflection angle changes of the follower plate 13.

[0069] In this embodiment, when the pitch angle and deflection angle of the electric drill 16 are adjusted, by pulling the pulling frame 18, when the connecting shaft 17 abuts against one side wall of the connecting groove 1801, the moving frame 15 can be driven to move along the length direction of the follower plate 13, so as to perform the drilling operation. This enables construction workers to stand on the bridge, tunnel, or slope for construction when drilling holes in the curb protrusions in the curved areas of the bridge, tunnel, or slope, without the need to enter the outside of the bridge, tunnel, or slope, avoiding the difficulties in operation caused by narrow space and the risk of working at heights.
