Description

Technical Field

[0001] This invention relates to the field of drilling rig construction technology, and in particular to a multifunctional horizontal directional drilling rig and anchoring device. Background Technology

[0002] With the development of construction technology, the use of machinery has improved the efficiency of construction and the accuracy of construction. Nowadays, vertical drilling rigs and horizontal directional drilling rigs are used in drilling operations. Horizontal directional drilling rigs can operate without excavating the surface, so detailed geological surveys are required before construction.

[0003] Currently, when using horizontal directional drilling rigs, the anchor plate needs to be vertically fixed in advance. Existing equipment involves manually installing the anchor bolts onto the anchoring head. However, during actual operation, the anchor bolts tend to tilt due to the influence of the horizontal fixing posture and the gravity of the anchor bolts, affecting the stability and levelness of the anchoring.

[0004] Based on this, the present invention designs a multifunctional horizontal directional drilling rig and anchoring device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional horizontal directional drilling rig and anchoring device, which aims to solve the technical problems existing in the prior art mentioned in the background.

Alignment mechanism: used to rotate the anchor head one revolution; Downward pressing mechanism: used to drive the anchor head to move vertically; Rotating mechanism: used to drive the anchor head to rotate; Moving mechanism: used to move the anchor head to the central axis of the semi-circular support block; Drive mechanism: Used to drive the semi-circular support block and anchor head to rotate synchronously.

[0007] Furthermore, the alignment mechanism includes a movable rod installed on the anchor plate surface corresponding to the anchor head, a sliding column head fixedly installed on the surface of the movable rod, a spiral groove that mates with the sliding column head on the inner wall of the anchor head, and a connecting ring rotatably installed on the surface of the anchor head, the connecting ring being connected to the pressing mechanism via a compression spring.

[0008] Furthermore, the pressing mechanism includes a pressing slide cylinder coaxially and fixedly connected to the moving rod. The inner wall of the pressing slide cylinder has a groove that cooperates with the anchor head. The end of the compression spring away from the connecting ring is connected to the pressing slide cylinder. The pressing slide cylinder passes through the lead screw slide plate and is rotatably connected to it. The pressing slide cylinder is connected to the output end of the rotating mechanism. The lead screw slide plate and the rotating lead screw form a helical pair transmission. The rotating lead screw is connected to the output end of the pressing motor. The pressing motor is fixedly installed on the L-shaped plate. The lead screw slide plate is slidably connected to the L-shaped plate. The L-shaped plate is fixedly installed on the moving mechanism.

[0009] Furthermore, the rotating mechanism includes a rotating motor fixedly mounted on the lead screw slide plate, and the output end of the rotating motor is connected to the lower pressure slide cylinder.

[0010] Furthermore, the moving mechanism includes a movable rotating cylinder slidably connected to the lower sliding cylinder, the movable rotating cylinder being rotatably connected to the fixed cylinder, an L-shaped plate being fixedly installed on the surface of the fixed cylinder, the fixed cylinder being fixedly installed on the sliding rod, the sliding rod being slidably connected to the driving mechanism, and a fixed arc surface block cooperating with the sliding rod being fixedly installed on the surface of the anchor plate.

[0011] Furthermore, the driving mechanism includes four drive motors fixedly installed on the anchor plate surface. Each drive motor has a gear set fixedly installed at its output end.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 9 and Figure 10 As shown, in one embodiment, a multifunctional horizontal directional drilling rig and anchoring device are proposed, the device comprising: Main plate 1: It is provided with anchor plate surface 101; Positioning mechanism 2: includes four sets of semi-circular support blocks 201 installed on the anchor plate surface 101 for supporting anchor screws, each set including two semi-circular support blocks 201, and also includes an anchor head 202 installed on the anchor plate surface 101 opposite to each set of semi-circular support blocks 201 for cooperating with the anchor screw. Alignment mechanism 3: used to drive the anchor head 202 to rotate one revolution; Pressing mechanism 4: used to drive the anchor head 202 to move vertically; Rotating mechanism 5: used to drive the anchor head 202 to rotate; Moving mechanism 6: used to move the anchor head 202 to the central axis of the semi-circular support block 201; Drive mechanism 7: used to drive the semi-circular support block 201 and anchor head 202 to rotate synchronously.

[0021] In practical applications, when anchoring screws are required for fixing, an external gripping device drives the anchor plate 101 to adhere to the wall being anchored in a vertical position. Figure 5 As shown, the anchoring screw is placed on the two semi-circular support blocks 201, so that the anchoring screw passes through the circular hole formed by the two semi-circular support blocks 201 and is in a vertically downward position, as shown. Figure 3 As shown, at this time, the drive mechanism 7 starts to operate. The operation of the drive mechanism 7 drives the semi-circular support block 201 and the anchor head 202 to revolve, rotating from a vertical state to a horizontal state. During the revolution, as... Figure 2 and Figure 4 As shown, at this time, the moving mechanism 6 drives the pressing mechanism 4 to move towards the central axis of the semicircular support block 201, which in turn drives the anchor head 202 to move closer to the central axis of the semicircular support block 201. When the semicircular support block 201 and the anchor head 202 are on the same central axis, the pressing mechanism 4 drives the anchor head 202 to move closer to the anchor head 202 position. After the anchor head 202 is attached to the anchor screw, the reaction force drives the anchor head 202 to rotate one revolution and engage with the anchor screw, thereby achieving the purpose of automatically and stably positioning the anchor screw. After the anchor head 202 and the anchor screw are engaged, the driving mechanism 7 drives the anchor screw to move to a horizontal state. Then, through the synchronous action of the rotating mechanism 5 and the pressing mechanism 4, the anchor screw is driven to rotate and feed into the wall, achieving the purpose of automatically fixing the anchor screw.

[0022] like Figure 8 As shown, in a preferred embodiment of the present invention, the alignment mechanism 3 includes a movable rod 301 mounted on the anchor plate surface 101 and corresponding to the anchor head 202. A sliding groove column head 302 is fixedly mounted on the surface of the movable rod 301. A spiral groove 303 that cooperates with the sliding groove column head 302 is opened on the inner wall of the anchor head 202. A connecting ring 304 is rotatably mounted on the surface of the anchor head 202. The connecting ring 304 is connected to the pressing mechanism 4 through a compression spring 305.

[0023] In practical applications, when the anchor head 202 contacts the anchor screw, as in the embodiments of the present invention... Figure 8As shown, under the action of the reaction force, the compression spring 305 is compressed, and the anchor head 202 is driven to rotate one revolution through the cooperation of the sliding column head 302 and the spiral groove 303. Under the action of the elastic potential energy of the compression spring 305, the anchor head 202 and the anchor screw are connected to each other, thereby achieving the purpose of automatic connection.

[0024] like Figure 4 , Figure 6 and Figure 7 As shown, in another preferred embodiment of the present invention, the pressing mechanism 4 includes a pressing slide cylinder 401 coaxially and fixedly connected to the moving rod 301. The inner wall of the pressing slide cylinder 401 is provided with a sliding groove that cooperates with the anchor head 202. The end of the compression spring 305 away from the connecting ring 304 is connected to the pressing slide cylinder 401. The pressing slide cylinder 401 passes through the lead screw slide plate 402 and is rotatably connected to it. The pressing slide cylinder 401 is connected to the output end of the rotating mechanism 5. The lead screw slide plate 402 and the rotating lead screw 403 form a helical pair transmission. The rotating lead screw 403 is connected to the output end of the pressing motor 404. The pressing motor 404 is fixedly installed on the L-shaped plate 405. The lead screw slide plate 402 is slidably connected to the L-shaped plate 405. The L-shaped plate 405 is fixedly installed on the moving mechanism 6.

[0025] In practical applications, when the anchor head 202 moves to the same central axis as the semi-circular support block 201, as in the embodiments of the present invention... Figure 4 As shown, the pressing motor 404 starts running at this time. The operation of the pressing motor 404 drives the lead screw slide plate 402 to move towards the semi-circular support block 201 through the screw pair transmission. This, in turn, drives the pressing slide cylinder 401 to move towards the semi-circular support block 201. This, in turn, drives the alignment mechanism 3 to approach the semi-circular support block 201 to complete the engagement between the anchor head 202 and the anchor screw. After the engagement is completed, the anchor screw moves to a horizontal state. At this time, through the synchronous operation of the pressing mechanism 4 and the rotating mechanism 5, the anchor screw is rotated and fed, thereby achieving the purpose of automatically fixing the anchor screw.

[0026] like Figure 4 As shown, in another preferred embodiment of the present invention, the rotating mechanism 5 includes a rotating motor 501 fixedly mounted on the lead screw slide plate 402, and the output end of the rotating motor 501 is connected to the pressing slide cylinder 401.

[0027] In practical application, after the anchor head 202 and the anchor screw are properly engaged, the continued movement of the pressing mechanism 4 causes the semi-circular support block 201 and the pressing slide cylinder 401 to further engage. At this time, the driving mechanism 7 drives the anchor screw to a horizontal position. Figure 4As shown, at this time, the rotating motor 501 starts to run. The operation of the rotating motor 501 drives the downward sliding cylinder 401 to rotate, which in turn drives the anchor head 202 to rotate. The rotation of the anchor head 202 drives the anchor screw to rotate synchronously. At the same time, in conjunction with the operation of the downward pressing mechanism 4, the anchor screw is fed and fixed.

[0028] like Figure 2 and Figure 4 As shown, in another preferred embodiment of the present invention, the moving mechanism 6 includes a movable rotating cylinder 601 slidably connected to the lowering sliding cylinder 401, the movable rotating cylinder 601 being rotatably connected to the fixed cylinder 602, an L-shaped plate 405 being fixedly installed on the surface of the fixed cylinder 602, the fixed cylinder 602 being fixedly installed on the sliding rod 603, the sliding rod 603 being slidably connected to the driving mechanism 7, and a fixed arc surface block 604 cooperating with the sliding rod 603 being fixedly installed on the anchor plate surface 101.

[0029] In practical applications, when the semi-circular support block 201 and anchor head 202 are driven to revolve by the driving mechanism 7, as... Figure 2 and Figure 4 As shown, at this time, the sliding rod 603 and the fixed arc block 604 work together to drive the fixed cylinder 602 to move towards the central axis of the semicircular support block 201, which in turn drives the pressing mechanism 4 to move towards the central axis of the semicircular support block 201. The movement of the pressing mechanism 4 drives the anchor head 202 to move towards the central axis of the semicircular support block 201. When the semicircular support block 201 and the anchor head 202 are on the same central axis, the sliding rod 603 slides stably on the trajectory of the fixed arc block 604, so that the anchor head 202 and the semicircular support block 201 are always on the same central axis. The movement of the moving mechanism 6 makes the anchor head 202 and the semicircular support block 201 on the same central axis to facilitate the early feeding of anchor screws, so that anchor screws of different lengths can be fed quickly.

[0030] like Figure 3 As shown, in another preferred embodiment of the present invention, the driving mechanism 7 includes four driving motors 701 fixedly installed on the anchor plate surface 101. Each driving motor 701 has a gear rod assembly 702 fixedly installed at its output end. The gear rod assembly 702 meshes with two rotating gears 703 respectively. Each rotating gear 703 is rotatably connected to the anchor plate surface 101. A connecting frame 704 is fixedly installed on the surface of the rotating gear 703. A connecting block 705 is also fixedly installed on the surface of the rotating gear 703. A guide cylinder 706 is fixedly installed on the surface of the connecting block 705. The sliding rod 603 is slidably connected to the guide cylinder 706, and the fixed cylinder 602 is connected to the guide cylinder 706 by a spring.

[0031] In practical applications, after the anchor screws are loaded, as in the embodiments of the present invention... Figure 3 As shown, at this time, the drive motor 701 starts to run. The movement of the drive motor 701 drives the rotating gear 703 to rotate through the meshing action of the gear rod group 702 and the rotating gear 703. The rotation of the rotating gear 703 drives the semi-circular support block 201 and the anchor head 202 to revolve synchronously through the connecting frame 704 and the guide cylinder 706, thereby achieving the purpose of automatically moving to the anchoring position.

[0032] like Figure 11 As shown, in another preferred embodiment of the present invention, the device further includes a separation mechanism 8. The separation mechanism 8 includes an arc-shaped plate 805 fixedly mounted on a rotating gear 703. A movable slider 803 is slidably mounted on the surface of the arc-shaped plate 805. The movable slider 803 is connected to the arc-shaped plate 805 through a tension spring 804. A column head rod 802 is slidably mounted on the inner wall of the movable slider 803. A separation rod 801 is fixedly mounted on the surface of the column head rod 802. A semi-circular support block 201 is fixedly mounted on the surface of the separation rod 801. The column head rod 802 and the movable slider 803 are connected through a return spring. A ramp block 806 that cooperates with the column head rod 802 is fixedly mounted on the surface of the arc-shaped plate 805.

[0033] In practical application, when the anchoring screw is rotated and fed by the movement of the pressing mechanism 4 and the rotating mechanism 5, the anchoring screw compresses the two semi-circular support blocks 201 and moves synchronously. It should be noted that the elastic potential energy of the tension spring 804 is greater than that of the compression spring 305. Therefore, when the anchoring head 202 contacts the anchoring screw, the compression spring 305 will be compressed first. The movement of the semi-circular support blocks 201 drives the column head rod 802 to move synchronously through the separating rod 801. At this time, the moving slider 803 slides on the arc plate 805. Figure 11 As shown, when the column head rod 802 moves to the ramp block 806 and engages with the ramp block 806, the trajectory of the ramp block 806 drives the two semi-circular support blocks 201 to move in the opposite direction. This ensures that the anchoring screw is not interfered with by the semi-circular support blocks 201 and is fully inserted into the wall to complete the fixing of the anchoring screw. It should be noted that the reverse movement of 201 occurs after the anchoring screw has partially entered the wall, thus preventing the screw from falling off.

[0034] like Figure 4 and Figure 8 As shown, in another preferred embodiment of the present invention, the mating end of the chute head 302 and the spiral groove 303 is provided with a rotating ball, and the mating end of the sliding rod 603 and the fixed arc surface block 604 is also provided with a rotating ball.

[0035] In practical applications, the present invention converts sliding friction into rolling friction by setting a rotating ball, thereby improving motion stability and increasing the service life of parts.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
