The connecting piece first uses an L-shaped limiting groove to cooperate with the positioning rod on the anchor rod to achieve movable clamping of the two, and then uses a positioning threaded rod to cooperate with a pressing plate to achieve clamping and positioning of the anchor rod. Due to the poor reliability of the above connection, the phenomenon of rod detachment is likely to occur when the anchor rod is pulled out after pile driving, which affects the stability of the construction of the anchoring device.

Detailed implementation manner

[0038] The technical solution in the embodiment of the present application aims to solve the problem of poor stability during the construction of the anchoring device in the above solution. The general idea is as follows:

[0039] Embodiment:

[0040] Please refer to Figure 1 - Figure 2 , a horizontal directional drilling machine anchoring device, including a mounting frame 1, a first mounting plate 2 and an anchoring rod 3. A first mounting plate 2 is provided on one side of the mounting frame 1, and the mounting frame 1 is slidably connected with the anchoring rod 3. It also includes a pile driving mechanism 4, a rope winding mechanism 5 and a lifting mechanism 6. Among them, the upper side of the left part of the mounting frame 1 is connected with a first mounting plate 2 for installing the horizontal directional drilling machine. The mounting frame 1 is slidably connected with the anchoring rod 3 for making contact with the ground for clamping. The bottom of the anchoring rod 3 is designed in a conical shape, and a through hole for the anchoring rod 3 to slide is opened on the mounting frame 1 to facilitate insertion into the ground. A pile driving mechanism 4 for driving the anchoring rod 3 is provided on the mounting frame 1, and a rope winding mechanism 5 for pulling the pile driving mechanism 4 is provided on the right part of the mounting frame 1. The lifting mechanism 6 is used to make it more stable when pulling out the anchoring rod 3 and prevent it from falling off, that is, the stability of the anchoring device during construction is improved.

[0041] Please refer to Figure 1 - Figure 6, the pile driving mechanism 4 is arranged on the upper surface of the mounting frame 1 and can drive the anchoring rod 3 to move longitudinally. The pile driving mechanism 4 includes a guide frame 41, guide wheels 42, a pulling rope 43, a falling block 44, a second mounting plate 45, a clamping block 46 and a first spring 47. The guide frame 41 is installed on the top of the mounting frame 1, and a pair of guide wheels 42 are provided at its top, and a pulling rope 43 is wound around the guide wheels 42. One end of the pulling rope 43 is connected to a second mounting plate 45. Clamping blocks 46 are symmetrically slidably connected to both sides of the second mounting plate 45. First springs 47 are connected between the clamping blocks 46 and the second mounting plate 45, and a falling block 44 is jointly clamped between the two clamping blocks 46. Chamfers are provided on the opposite sides of the upper ends of the two clamping blocks 46, and auxiliary blocks that are extrusion-fitted with the chamfered parts of the clamping blocks 46 are provided on both sides of the inner top end of the guide frame 41.

[0042] The rope winding mechanism 5 is arranged on the other side of the mounting frame 1 and can be used to pull the pile driving mechanism 4. The rope winding mechanism 5 includes a wire reel 51, a motor 52, a fixed frame 53 and a transmission belt 54. The fixed frame 53 is installed on the other side of the mounting frame 1, and a wire reel 51 is rotatably connected to the upper part thereof and a motor 52 is fixedly installed. Pulley wheels are connected to the output end of the motor 52 and one end of the wire reel 51, and a transmission belt 54 is wound around the two pulley wheels. The other end of the pulling rope 43 is wound around the wire reel 51.

[0043] In this application, the driving mechanism 4 and the rope winding mechanism 5 are used in cooperation to drive the construction of the anchor rod 3. During specific use, the worker fixes the horizontal directional drill on the first mounting plate 2 through bolts, and then starts the motor 52. The output shaft of the motor 52 drives the movement of the transmission belt 54, so that the wire wheel 51 rotates. The rotation of the wire wheel 51 winds up the pulling rope 43, so that the second mounting plate 45 moves upward. The second mounting plate 45 drives the clamping blocks 46 to move upward. The clamping blocks 46 drive the falling block 44 to move upward. The falling block 44 drives the anchor rod 3 to move upward. When the clamping blocks 46 touch the guide frame 41, the guide frame 41 will push the clamping blocks 46 away from each other, so that the first springs 47 are compressed. At this time, the clamping blocks 46 are no longer clamped with the falling block 44. Under the action of the self-gravity of the falling block 44 and the anchor rod 3, the falling block 44 drives the anchor rod 3 to fall downward and hammer into the ground. Then the motor 52 is turned off, so that the horizontal directional drill can be more stable during operation. When it is necessary to pull out the anchor rod 3 from the ground, the motor 52 is controlled to make the output shaft of the motor 52 rotate in the reverse direction, so that the wire wheel 51 releases the pulling rope 43. Under the action of the gravity of the second mounting plate 45, the second mounting plate 45 drives the clamping blocks 46 to move downward. At this time, the clamping blocks 46 are disengaged from the guide frame 41. Under the action of the first spring 47, the clamping blocks 46 slide back to the side close to each other. When the bottom of the clamping block 46 touches the top of the falling block 44, the motor 52 is turned off. The worker needs to press down the second mounting plate 45 to make the clamping blocks 46 be clamped with the falling block 44 again. During this process, the bottom of the clamping blocks 46 is squeezed by the falling block 44 and starts to slide away from each other. The first springs 47 are deformed. When the falling block 44 no longer squeezes the clamping blocks 46, under the action of the first spring 47, the clamping blocks 46 are clamped with the falling block 44 again. Then the motor 52 is controlled to make the output shaft of the motor 52 rotate, so that the wire wheel 51 rotates to wind up the pulling rope 43. The second mounting plate 45 moves upward. The second mounting plate 45 drives the clamping blocks 46 to move upward. The clamping blocks 46 drive the falling block 44 to move upward. The falling block 44 drives the anchor rod 3 to move upward, so that the anchor rod 3 is separated from the ground. After the separation, the motor 52 is turned off. In summary, the motor 52 drives the wire wheel 51 to wind up the pulling rope 43, so that the falling block 44 drives the anchor rod 3 to move upward. Finally, under the action of the gravity of the anchor rod 3 and the falling block 44, the anchor rod 3 can hammer into the ground through gravitational potential energy, thus completing the fixation and ensuring the stability of the horizontal directional drill during operation.

[0044] Please refer to Figure 1 、 Figure 6 - Figure 8, a lifting mechanism 6 is provided on the mounting frame 1 and is used to separate the anchoring rod 3 from the pile driving mechanism 4. The lifting mechanism 6 includes two pull rods 61, a sliding sleeve 62, a wedge ring 63, a mounting block 64, a clamping rod 65, a second spring 66, a clamping rod 67 and a third spring 68. The two pull rods 61 are respectively connected to both sides of the mounting frame 1. Sliding sleeves 62 capable of sliding on the corresponding guide frames 41 are connected to both sides of the falling block 44. A wedge ring 63 is slidably connected between the sliding sleeves 62. Mounting blocks 64 are connected to the outside of the sliding sleeves 62. Clamping rods 65 are slidably connected to the mounting blocks 64. Second springs 66 are connected between the clamping rods 65 and the mounting blocks 64. The second springs 66 are all wound around the clamping rods 65. Sliding cavities are provided on both sides of the inner wall of the falling block 44, and clamping rods 67 are slidably connected in the sliding cavities. Third springs 68 are connected between the clamping rods 67 and the falling block 44. The third springs 68 are all wound around the clamping rods 67. Claw slots 69 for inserting the clamping rods 67 are provided on both the wedge ring 63 and the anchoring rod 3. Among them, as the falling block 44 and the anchoring rod 3 fall, during the falling process, the falling block 44 will drive the clamping rods 67 to fall. When the clamping rods 67 all contact the wedge ring 63, under the extrusion of the wedge ring 63, the clamping rods 67 all slide towards the side close to each other, and the third springs 68 are all compressed. Then the clamping rods 67 will all be clamped with the claw slots 69, and the third springs 68 are slightly reset. At the same time, the falling block 44 will squeeze the clamping rods 65, so that the clamping rods 65 all slide towards the side away from each other, and the second springs 66 are all compressed. When the worker needs to pull out the anchoring rod 3, as the falling block 44 drives the anchoring rod 3 to move upward, at this time, under the action of the clamping rod 67, the falling block 44 and the anchoring rod 3 are clamped more firmly. At the same time, the wedge ring 63 will also slide upward under the drive of the clamping rod 67, so that the mounting blocks 64 all slide upward. The mounting blocks 64 drive the clamping rods 65 to slide upward. When the clamping rods 65 all contact the pull rods 61, the mounting blocks 64 can no longer slide upward, so that the sliding sleeves 62 can no longer slide upward, so that the wedge ring 63 stops moving. At this time, the falling block 44 continues to move upward and reset, so that the clamping rod 67 is disengaged from the wedge ring 63. As the clamping rod 67 is completely disengaged from the wedge ring 63, under the action of the third spring 68, the clamping rods 67 all slide towards the side away from each other and are disengaged from the anchoring rod 3. As the falling block 44 moves upward and resets, the falling block 44 no longer squeezes the clamping rods 65. Under the action of the second spring 66, the clamping rods 65 all slide towards the side close to each other and reset. In summary, through the extrusion of the wedge ring 63 on the clamping rod 67, the clamping between the falling block 44 and the anchoring rod 3 is made more firm, so that when pulling out the anchoring rod 3, it can be more stable and will not fall off.

[0045] Please refer to Figure 1 , Figure 9 and Figure 10, the horizontal directional drill anchoring device further includes a fixing mechanism 7 for strengthening the fixation of the anchor rod 3. The fixing mechanism 7 includes a sliding rod 71, a first connecting rod 72, a fourth spring 73, a fixing rod 74, a fifth spring 75 and a conical block 76. The inside of the anchor rod 3 is hollow-designed, and a sliding rod 71 is slidably connected to the upper part thereof. The bottom of the sliding rod 71 is connected to a first connecting rod 72. A fourth spring 73 is connected between the first connecting rod 72 and the anchor rod 3, and the fourth spring 73 is wound around the first connecting rod 72. Five fixing rods 74 are slidably connected to the lower part of the anchor rod 3. Fifth springs 75 are connected between the fixing rods 74 and the anchor rod 3 respectively, and the fifth springs 75 are wound around the fixing rods 74 respectively. The bottom of the first connecting rod 72 is connected to a conical block 76. Among them, as the anchor rod 3 drops and hits the ground, when the sliding rod 71 touches the top of the mounting frame 1, the mounting frame 1 will push the sliding rod 71, so that the sliding rod 71 slides upward. The sliding rod 71 drives the first connecting rod 72 to slide upward, so that the fourth spring 73 is compressed by force. At the same time, it drives the conical block 76 to move upward. The conical block 76 moves upward and squeezes the five fixing rods 74, so that the fixing rods 74 all slide to the side away from each other, and the fifth springs 75 are all compressed by force. Furthermore, the fixing rods 74 contact the ground, enhancing the stability of the connection between the anchor rod 3 and the ground. As the anchor rod 3 slides upward and resets, at this time the mounting frame 1 no longer pushes the sliding rod 71. Under the action of the fourth spring 73, the sliding rod 71 slides downward and resets, driving the first connecting rod 72 to slide downward and reset. The first connecting rod 72 drives the conical block 76 to move downward and reset, so that the fixing rods 74 are no longer squeezed. Under the action of the fifth spring 75, the fixing rods 74 all slide to the side close to each other and reset and disengage from the ground connection. In summary, by the conical block 76 squeezing the fixing rods 74, the fixing rods 74 all slide to the side away from each other and are connected to the ground, further enhancing the stability of the anchor rod 3.

[0046] Please refer to Figure 1 and Figure 11 , the horizontal directional drill anchoring device further includes a mud scraping mechanism 8 for cleaning the anchor rod 3. The mud scraping mechanism 8 includes a fixing block 81, a second connecting rod 82 and a scraping plate 83. Six fixing blocks 81 are connected to the upper part of the mounting frame 1. Second connecting rods 82 are connected to the sides of the fixing blocks 81 close to each other. A scraping plate 83 is connected between the sides of the second connecting rods 82 close to each other. The scraping plate 83 is slidably sleeved outside the anchor rod 3. Among them, as the anchor rod 3 moves upward and resets, the part of the anchor rod 3 connected to the ground will stick to mud. When the mud moves upward with the anchor rod 3, it will contact the scraping plate 83. Under the action of the scraping plate 83, the mud on the surface of the anchor rod 3 will be scraped off, thus achieving the effect of cleaning the anchor rod 3 and reducing the work of workers cleaning the anchor rod 3.

[0047] Please refer to Figure 1 , Figure 12 andFigure 13 , the horizontal directional drill anchoring device further includes a clamping mechanism 9 for installing the horizontal directional drill. The clamping mechanism 9 includes a first connecting block 91, a second connecting block 92 and a bolt 93. The first connecting block 91 is connected to the first mounting plate 2 by bolts. The second connecting block 92 is clamped on the left side of the first connecting block 91. A bolt 93 is slidably connected between the first connecting block 91 and the second connecting block 92. Among them, in order to facilitate the workers to install the horizontal directional drill, before installing the horizontal directional drill, the bolt 93 needs to be pulled forward, and then the second connecting block 92 is pulled to the left to disengage the second connecting block 92 from the first connecting block 91. Then, the second connecting block 92 and the horizontal directional drill are fixed by bolts. Then, the second connecting block 92 is clamped with the first connecting block 91. Finally, the bolt 93 is inserted between the first connecting block 91 and the second connecting block 92 to complete the fixation. In summary, by connecting the second connecting block 92 with the horizontal directional drill, then clamping the second connecting block 92 with the first connecting block 91, and finally fixing it with the bolt 93, it saves the time for workers to fix the horizontal directional drill with bolts every time.

[0048] The working principle of this application is as follows:

[0049] It is connected to the horizontal directional drill through the second connecting block 92. Then, the second connecting block 92 is clamped with the first connecting block 91. Finally, it is fixed by the pin 93, saving the time for workers to fix the horizontal directional drill with bolts every time. Then, the motor 52 is started. The output shaft of the motor 52 drives the conveyor belt 54 to move, so that the wire wheel 51 rotates. The rotation of the wire wheel 51 winds up the pulling rope 43, so that the second mounting plate 45 moves upward. The second mounting plate 45 drives the clamping blocks 46 to move upward. The clamping blocks 46 drive the falling block 44 to move upward. The falling block 44 drives the anchoring rod 3 to move upward. When the clamping blocks 46 all touch the guide frame 41, the guide frame 41 will push the clamping blocks 46 to the side away from each other, so that the first springs 47 are all compressed under force. At this time, the clamping blocks 46 are no longer clamped with the falling block 44. Under the action of the self-gravity of the falling block 44 and the anchoring rod 3, the falling block 44 drives the anchoring rod 3 to fall downward and hammer into the ground. Then, the motor 52 is turned off, so that the horizontal directional drill can be more stable during operation. When it is necessary to pull out the anchoring rod 3 from the ground, the motor 52 is controlled to make the output shaft of the motor 52 rotate in the reverse direction, so that the wire wheel 51 releases the pulling rope 43. Under the action of the gravity of the second mounting plate 45, the second mounting plate 45 drives the clamping blocks 46 to move downward. At this time, the clamping blocks 46 are all separated from the guide frame 41. Under the action of the first springs 47, the clamping blocks 46 slide back to the side close to each other. When the bottom of the clamping blocks 46 touches the top of the falling block 44, the motor 52 is turned off. Workers need to press down the second mounting plate 45 to make the clamping blocks 46 be clamped with the falling block 44 again. During this process, the bottoms of the clamping blocks 46 are all squeezed by the falling block 44 and start to slide to the side away from each other. The first springs 47 are deformed under force. When the falling block 44 no longer squeezes the clamping blocks 46, under the action of the first springs 47, the clamping blocks 46 are clamped with the falling block 44 again. Through repeated movements, stable anchoring operation is achieved;

[0050] During the operation process, as the falling block 44 and the anchoring rod 3 drop, during the dropping process, the falling block 44 will drive the clamping rod 67 to drop. When the clamping rods 67 all come into contact with the wedge-shaped ring 63, under the extrusion of the wedge-shaped ring 63, the clamping rods 67 all slide towards the side close to each other, and the third springs 68 are all compressed. After that, the clamping rods 67 will all be clamped with the clamping grooves 69, and the third springs 68 are slightly reset. At the same time, the falling block 44 will extrude the clamping rods 65, so that the clamping rods 65 all slide towards the side away from each other, and the second springs 66 are all compressed. When the worker needs to pull out the anchoring rod 3, as the falling block 44 drives the anchoring rod 3 to move upward, at this time, under the action of the clamping rod 67, the falling block 44 is more firmly clamped with the anchoring rod 3. At the same time, the wedge-shaped ring 63 will also slide upward under the drive of the clamping rod 67, so that the mounting blocks 64 all slide upward. The mounting blocks 64 drive the clamping rods 65 to slide upward. When the clamping rods 65 all come into contact with the pull rod 61, the mounting blocks 64 can no longer slide upward, so that the sliding sleeves 62 can no longer slide upward, so that the wedge-shaped ring 63 stops moving. At this time, the falling block 44 continues to move upward and reset, so that the clamping rod 67 is disengaged from the wedge-shaped ring 63. As the clamping rod 67 is completely disengaged from the wedge-shaped ring 63, under the action of the third spring 68, the clamping rods 67 all slide towards the side away from each other and reset and are disengaged from the anchoring rod 3. As the falling block 44 moves upward and resets, the falling block 44 no longer extrudes the clamping rod 65. Under the action of the second spring 66, the clamping rods 65 all slide towards the side close to each other and reset, that is, through the extrusion of the wedge-shaped ring 63 on the clamping rod 67, the clamping between the falling block 44 and the anchoring rod 3 is more firm, so that when the anchoring rod 3 is pulled out, it can be more stable and will not fall off.

[0051] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present application, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present application.
