Description

Technical Field

[0001] The invention relates to the technical field of drilling, and in particular to a horizontal directional drilling device for dark excavation of an electric power tunnel. Background Art

[0002] The horizontal directional drilling device for electric power tunnel is a device used for underground construction, especially suitable for cable laying, pipeline installation and other projects in cities or under complex geological conditions. This device can reduce the impact on ground traffic and the environment while ensuring the safety and efficiency of construction.

[0003] The existing horizontal directional drilling device for electric power tunnel excavation is to hoist the drill rod with the drill bit between the propulsion frame and the limit frame, and then push the drill rod through the limit frame to the ground to drill a hole by the propulsion frame, and then splice multiple sections of drill rod to continue drilling, so as to complete the drilling work. However, when the drill rod is drilled into the ground and waits for splicing, it is easy to fall off the limit frame due to soil pressure, which affects the safety and efficiency of construction.

[0004] Therefore, a horizontal directional drilling device for electric power tunneling has been developed that can limit and lock the drill rods to be spliced ​​to prevent the drill rods from falling off the limit frame due to soil pressure, thereby improving construction safety and efficiency. Summary of the invention

[0005] In order to overcome the disadvantage of the existing horizontal directional drilling device for electric tunnel digging, that when the drill rod is drilled into the ground waiting for splicing, it is easy to fall off from the limit frame due to soil pressure, thereby affecting the safety and efficiency of construction, the present invention provides a horizontal directional drilling device for electric tunnel digging that can limit and lock the drill rod to be spliced, thereby preventing the drill rod from falling off from the limit frame due to soil pressure, thereby improving the safety and efficiency of construction.

[0006] The technical implementation scheme of the present invention is: a horizontal directional drilling device for dark excavation of a power tunnel, comprising a mounting frame, moving wheels, a drilling mechanism and a locking mechanism, wherein a plurality of moving wheels are rotatably connected to the lower side of the mounting frame, a drilling mechanism capable of horizontal directional drilling is provided on the mounting frame, and a locking mechanism is provided on the drilling mechanism.

[0007] Furthermore, the drilling mechanism includes a guide frame, a propulsion frame, a limit frame, a drill rod and a drill bit. The guide frame is slidably provided on the upper side of the mounting frame, the propulsion frame is slidably provided on the upper left side of the guide frame, and the limit frame is slidably provided on the upper right side of the guide frame. The drill rod is clamped on the propulsion frame, the drill rod passes through the limit frame, and the drill bit is connected to the right side of the drill rod. The drill rod is hoisted between the propulsion frame and the limit frame, and then the propulsion frame is moved to the right on the guide frame, so that the propulsion frame pushes the drill rod to move to the right and rotate, so that the drill bit drills into the ground, the limit frame limits the drill rod, and then the propulsion frame is reset, and then the next section of the drill rod is hoisted on the propulsion frame, so that the drill rod is spliced ​​to continue drilling into the ground until the drilling is completed.

[0008] Furthermore, the locking mechanism includes a push rod, a support frame, a first telescopic rod, a first pressure spring, a push frame, a friction wheel, a torsion spring, a second telescopic rod, a second pressure spring and a limit block. The right sides of the front and rear parts of the propulsion frame are connected to the push rod, the front and rear sides of the upper part of the limit frame are connected to the support frame, the lower part of the support frame is connected to the first telescopic rod, the telescopic end of the first telescopic rod is connected to the push frame, the push rod is squeezed and matched with the adjacent top frame, the top frame is connected to the first pressure spring between the connected first telescopic rod, the top frame is rotatably connected to the friction wheel, and multiple torsion springs are connected between the friction wheel and the connected top frame, the right side of the lower part of the support frame is connected to the second telescopic rod, the telescopic end of the second telescopic rod is connected to the limit block, the top frame is squeezed and matched with the limit block, and the second telescopic rod is connected to the limit block. When the top frame moves close to each other, the limit block is squeezed, and then the limit block is engaged with the top frame through the force of the second pressure spring. When the drill rod slides to the right, the drill rod pushes the friction wheel to rotate. At this time, the top frame cannot move, and the drill rod cannot push the friction wheel to rotate. When the drill rod continues to slide to the right and pushes the friction wheel to rotate, the friction wheel presses the drill rod, and the torsion spring deforms. After the next section of the drill rod is spliced, the limit block is pulled to the right and separated from the top frame, causing the first pressure spring to rebound and the first telescopic rod to recover, thereby causing the friction wheel to separate from the drill rod, and the torsion spring recovers, driving the friction wheel to reset.

[0009] Furthermore, wedge blocks are provided on the upper sides of the top frames.

[0010] Furthermore, the friction wheels are all eccentric wheels.

[0011] Furthermore, it also includes a clamping mechanism, which includes a motor, a bidirectional screw, a movable frame and a first rotating wheel. The motor is connected to the front side of the lower right part of the limit frame, and the bidirectional screw is connected to the motor output shaft. The bidirectional screw is rotatably connected to the limit frame, and the front and rear parts of the bidirectional screw are both threadedly connected to the movable frame. The movable frame is slidably connected to the limit frame, and the first rotating wheel is rotatably connected to the side where the upper and lower parts of the movable frame are close to each other. When the drill rod is drilling, the motor is started to drive the bidirectional screw to rotate, so that the movable frames are close to each other until the first rotating wheel contacts the drill rod.

[0012] Furthermore, an auxiliary mechanism is also included, which includes a third telescopic rod, a pressure-bearing frame, a second rotating wheel and a third pressure spring. Two third telescopic rods are connected to the right side of the guide frame, and the pressure-bearing frame is connected between the telescopic ends of the third telescopic rod. The front and rear parts of the pressure-bearing frame are rotatably connected to the second rotating wheels, and the second rotating wheels are in contact with the drill rod. A third pressure spring is connected between the third telescopic rod and the pressure-bearing frame. After the drill rod passes through the limit frame, it contacts the second rotating wheel on the pressure frame, and the third pressure spring applies an upward force to the pressure frame, so that the second rotating wheel supports the drill rod.

[0013] Furthermore, the pressure-bearing frame is arc-shaped.

[0014] Furthermore, it also includes an adjusting mechanism, which includes a first connecting block, a cylinder, a fixed frame, a rotating telescopic plate and a second connecting block. The guide frame is connected to two left and right first connecting blocks on the front and rear sides, the first connecting blocks are rotatably connected to the cylinder, the telescopic end of the cylinder is rotatably connected to the fixed frame, the fixed frame is rotatably connected to the rotating telescopic plate, the upper part of the rotating telescopic plate is rotatably connected to the second connecting block, and the second connecting blocks are connected to the guide frame. After the guide frame moves to the specified position, the cylinder on the first connecting block is started to place the fixed frame on the ground, and the rotating telescopic plate is rotated so that the guide frame is tilted to a certain angle.

[0015] Furthermore, it also includes a connecting mechanism, which includes a support block and a hook ring. The left and right parts of the guide frame are connected to the front and rear support blocks, and the support blocks are connected to the hook ring. When the left part of the guide frame is placed on a mobile vehicle, it is connected to the mobile vehicle through the hook ring on the left, so that the guide frame is fixed on the mobile vehicle. When the position of the guide frame needs to be moved, the guide frame can be pulled to move by the hook ring on the right.

[0016] The present invention has the following advantages: 1. When the drill rod slides to the right, the drill rod pushes the friction wheel to rotate. At this time, the top frame cannot move, and the drill rod cannot push the friction wheel to rotate, thereby achieving the effect of limiting and locking the drill rods to be spliced, preventing the drill rods from falling off the limit frame due to soil pressure, and improving construction safety and efficiency.

[0017] 2. When drilling with a drill rod, the present invention starts the motor to drive the bidirectional screw rod to rotate, so that the movable frames are close to each other until the first rotating wheel contacts the drill rod, thereby achieving the effect of limiting the drill rod and facilitating the advancement of the drill rod.

[0018] 3. After the drill rod of the present invention passes through the limit frame, it contacts the second rotating wheel on the pressure frame. The third pressure spring applies an upward force to the pressure frame, so that the second rotating wheel supports the drill rod, thereby achieving the effect of improving the stability of the drill rod during drilling and avoiding damage to the drill rod.

[0019] 4. After the guide frame is moved to the specified position, the cylinder on the first connecting block is started to place the fixed frame on the ground, and the telescopic plate is rotated to tilt the guide frame to a certain angle, thereby achieving the effect of being able to adjust the angle of the guide frame to facilitate controlling the drilling angle of the drill rod.

[0020] 5. When the left part of the guide frame is placed on a mobile vehicle, the present invention connects the guide frame to the mobile vehicle through the hook ring on the left side, so that the guide frame is fixed on the mobile vehicle. When the position of the guide frame needs to be moved, the guide frame is pulled to move through the hook ring on the right side, thereby achieving the effect of being able to conveniently move and fix the guide frame and improve construction efficiency.

[0032] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] A horizontal directional drilling device for electric power tunneling, such as Figure 1-Figure 10 As shown, it includes a mounting frame 1, moving wheels 2, a drilling mechanism 3 and a locking mechanism 4. Four moving wheels 2 are rotatably connected to the lower side of the mounting frame 1. The mounting frame 1 is provided with a drilling mechanism 3, and the drilling mechanism 3 is provided with a locking mechanism 4.

[0034] like Figure 1-Figure 3 As shown, the drilling mechanism 3 includes a guide frame 31, a propulsion frame 32, a limit frame 33, a drill rod 34 and a drill bit 35. The guide frame 31 is slidably provided on the upper side of the mounting frame 1, the propulsion frame 32 is slidably provided on the upper left side of the guide frame 31, and the limit frame 33 is slidably provided on the upper right side of the guide frame 31. The drill rod 34 is clamped on the propulsion frame 32, the drill rod 34 passes through the limit frame 33, and the drill bit 35 is connected to the right side of the drill rod 34.

[0035] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the locking mechanism 4 includes a push rod 41, a support frame 42, a first telescopic rod 43, a first pressure spring 44, a push frame 45, a friction wheel 46, a torsion spring 47, a second telescopic rod 48, a second pressure spring 49 and a limit block 410. The push frame 32 is connected to the push rod 41 on both the front and rear right sides, the limit frame 33 is connected to the support frame 42 on both the front and rear sides, the support frame 42 is connected to the first telescopic rod 43 at the bottom, and the telescopic end of the first telescopic rod 43 is connected to the push frame 45. The top side of the push frame 45 is provided with a wedge block for extrusion and cooperation with the push rod 41. The push rod 41 is connected to the adjacent The top frame 45 is squeezed and fitted, and a first pressure spring 44 is connected between the top frame 45 and the first telescopic rod 43 connected thereto. A friction wheel 46 is rotatably connected to the top frame 45, and the friction wheel 46 is an eccentric wheel for clamping the drill rod 34. Two torsion springs 47 are connected between the friction wheel 46 and the top frame 45 connected thereto. A second telescopic rod 48 is connected to the right side of the lower part of the support frame 42, and a limit block 410 is connected between the telescopic ends of the second telescopic rod 48. The top frame 45 is squeezed and fitted with the limit block 410, and a second pressure spring 49 is connected between the second telescopic rod 48 and the limit block 410.

[0036] When using the present invention, first place the left part of the guide frame 31 on the mobile vehicle, then move the mounting frame 1 to the right part of the guide frame 31, so that the moving wheel 2 contacts the ground 0, and move the guide frame 31 to the designated drilling position by the mobile vehicle and the moving wheel 2. After the guide frame 31 moves to the designated position, the guide frame 31 is separated from the mobile vehicle, and then the drill rod 34 is hoisted between the propulsion frame 32 and the limiting frame 33, and then the propulsion frame 32 is moved to the right on the guide frame 31, so that the propulsion frame 32 pushes the drill rod 34 to move to the right and rotate, so that the drill bit 35 drills into the ground, the limiting frame 33 limits the drill rod 34, and then the propulsion frame 32 is reset, and then the next section of the drill rod 34 is hoisted on the propulsion frame 32, so that the drill rod 34 is spliced ​​to continue drilling into the ground until the drilling is completed. When the push frame 32 moves to the right, it drives the push rod 41 to move to the right. When the push rod 41 moves to the limit frame 33, the push frame 45 is squeezed to move closer to each other, and the first telescopic rod 43 and the first pressure spring 44 are stretched, so that the friction wheels 46 are close to each other and contact the drill rod 34. When the push frame 45 moves closer to each other, it squeezes the limit block 410, and then the limit block 410 and the push frame 45 are engaged with each other through the force of the second pressure spring 49. When the drill rod 34 slides to the right, the drill rod 34 pushes the friction wheel 46 to rotate. At this time, the push frame 45 cannot move, and the drill rod 34 cannot push the friction wheel 46 to rotate. The drill rod 34 is rotated, thereby limiting and locking the drill rod 34 to be spliced, preventing the drill rod 34 from falling off from the limit frame 33 due to soil pressure, thereby improving the safety and efficiency of construction. When the drill rod 34 continues to slide to the right and pushes the friction wheel 46 to rotate, the friction wheel 46 presses the drill rod 34, and the torsion spring 47 is deformed. After the next section of the drill rod 34 is spliced, the limit block 410 is pulled to the right and separated from the top frame 45, so that the first pressure spring 44 rebounds and the first telescopic rod 43 recovers, thereby causing the friction wheel 46 to separate from the drill rod 34, and the torsion spring 47 recovers, driving the friction wheel 46 to reset.

[0037] like Figure 1 , Figure 2 and Figure 7 As shown, it also includes a clamping mechanism 5, which includes a motor 51, a bidirectional screw rod 52, a movable frame 53 and a first rotating wheel 54. The motor 51 is connected to the front side of the lower right part of the limiting frame 33, and the bidirectional screw rod 52 is connected to the output shaft of the motor 51. The bidirectional screw rod 52 is rotatably connected to the limiting frame 33. The front and rear parts of the bidirectional screw rod 52 are both threadedly connected to the movable frame 53. The movable frame 53 is slidably connected to the limiting frame 33, and the first rotating wheel 54 is rotatably connected to the upper and lower sides of the movable frame 53 that are close to each other.

[0038] The clamping mechanism 5 of the device can be used to clamp the drill rod 34. When the drill rod 34 is drilling, the motor 51 is started to drive the bidirectional screw rod 52 to rotate, so that the movable frames 53 are close to each other until the first rotating wheel 54 contacts the drill rod 34, thereby limiting the drill rod 34 and facilitating the advancement of the drill rod 34.

[0039] like Figure 1 , Figure 2 and Figure 8 As shown, an auxiliary mechanism 6 is also included, and the auxiliary mechanism 6 includes a third telescopic rod 61, a pressure frame 62, a second rotating wheel 63 and a third pressure spring 64. The right side of the guide frame 31 is connected to the front and rear third telescopic rods 61, and the pressure frame 62 is connected between the telescopic ends of the third telescopic rod 61. The pressure frame 62 is arc-shaped, which is convenient for receiving the drill rod 34. The front and rear parts of the pressure frame 62 are both rotatably connected to the second rotating wheel 63, and the second rotating wheel 63 is in contact with the drill rod 34. The third telescopic rod 61 is connected to the pressure frame 62 with a third pressure spring 64.

[0040] By using the auxiliary mechanism 6 of the device, the drill rod 34 can be supported. After passing through the limit frame 33, the drill rod 34 contacts the second rotating wheel 63 on the pressure frame 62. The third pressure spring 64 applies an upward force to the pressure frame 62, so that the second rotating wheel 63 supports the drill rod 34, thereby improving the stability of the drill rod 34 during drilling and avoiding damage to the drill rod 34.

[0041] like Figure 1 , Figure 2 and Fig. 9 As shown, it also includes an adjustment mechanism 7, which includes a first connecting block 71, a cylinder 72, a fixed frame 73, a rotating telescopic plate 74 and a second connecting block 75. The front and rear sides of the guide frame 31 are connected to the left and right first connecting blocks 71, the first connecting blocks 71 are rotatably connected to the cylinder 72, the telescopic ends of the cylinder 72 are rotatably connected to the fixed frames 73, the fixed frames 73 are rotatably connected to the rotating telescopic plates 74, the upper parts of the rotating telescopic plates 74 are rotatably connected to the second connecting blocks 75, and the second connecting blocks 75 are connected to the guide frame 31.

[0042] By using the adjustment mechanism 7 of the device, the angle of the guide frame 31 can be adjusted. After the guide frame 31 moves to the specified position, the cylinder 72 on the first connecting block 71 is started to place the fixed frame 73 on the ground 0, and the telescopic plate 74 is rotated to make the guide frame 31 tilted to a certain angle, thereby playing a role in being able to adjust the angle of the guide frame 31 to facilitate controlling the drilling angle of the drill rod 34.

[0043] like Figure 1 , Figure 2 and Fig.10As shown, a connecting mechanism 8 is also included, and the connecting mechanism 8 includes a support block 81 and a hook ring 82. The left and right parts of the guide frame 31 are both connected to the front and rear support blocks 81, and the support blocks 81 are both connected to the hook ring 82.

[0044] By using the connecting mechanism 8 of the device, the guide frame 31 can be conveniently moved and fixed. When the left part of the guide frame 31 is placed on a moving vehicle, it is connected to the moving vehicle through the hook ring 82 on the left side, so that the guide frame 31 is fixed on the moving vehicle. When the position of the guide frame 31 needs to be moved, the guide frame 31 can be pulled to move by the hook ring 82 on the right side, thereby facilitating the movement and fixation of the guide frame 31 and improving the construction efficiency.

[0045] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
