Description

Technical Field

[0001] This utility model belongs to the field of drilling rig speed detection technology, specifically relating to a speed detection device for vertical shaft drilling rigs. Background Technology

[0002] When conducting geological surveys and mining mineral resources, vertical shaft drilling rigs are usually used to obtain core samples from the strata. Different mechanical transmission gears control the rotation speed of the drill rod and drill bit in the vertical shaft drilling rig to adapt to its drilling capacity and core recovery rate in various rock strata.

[0003] However, although the working efficiency of a vertical shaft drilling rig is closely related to its rotational speed, most vertical shaft drilling rigs only monitor the rotational speed through a speed sensor fixed to the lower end face of the rotary head. Moreover, the working environment of the speed sensor is generally relatively harsh. Therefore, after long-term operation, it is easily affected by external factors and provides incorrect speed data. This may further lead to the operator making incorrect gear changes to the vertical shaft drilling rig. In summary, there is an urgent need to provide a speed detection device for vertical shaft drilling rigs that can be easily replaced. Utility Model Content

[0004] The purpose of this invention is to provide a speed detection device for vertical shaft drilling rigs. This device can quickly release the speed sensor by the reverse movement of I-plate 1 and I-plate 2, ensuring timely replacement and maintenance of the speed sensor. Simultaneously, the reverse movement prevents the speed sensor from accidentally becoming loose. This invention effectively improves the problem in existing technologies where speed sensors are difficult to replace promptly after being damaged by external factors.

[0005] The technical solution to achieve the purpose of this utility model is as follows:

[0006] A speed detection device for a vertical shaft drilling rig includes the drilling rig, with mounting chambers located on the lower front side and inside the drilling rig. An I-shaped plate is passed through the top of the front mounting chamber. Rotary plates are rotatably connected to both sides of the bottom end of the I-shaped plate. Baffles are rotatably connected to the bottom ends of both rotating plates. An I-shaped plate is located below the baffles. Horizontal plates are slidably connected to both sides of the lower interior of the front mounting chamber. Irregularly shaped plates are slidably connected to the sides of the horizontal plates that are far apart. Vertical plates are slidably connected to the sides of the irregularly shaped plates that are close together. The top ends of the vertical plates are fixedly connected to the bottom end of the I-shaped plate. A mounting ring abuts against the side of the horizontal plate that is close together. A speed sensor is fixedly connected inside the mounting ring.

[0007] Furthermore, a bracket is fixedly connected to the lower front end of the drilling rig, a motor is fixedly connected to the top of the bracket, the output end of the motor passes through the bracket and is fixedly connected to a threaded rod, a slider is threadedly connected to the outside of the threaded rod, and the front end of the slider is fixedly connected to the middle of the rear end of the front installation chamber.

[0008] Furthermore, guide plates are fixedly connected to both sides of the upper part of the front installation compartment, and the top of the side baffles are slidably connected to the bottom of the guide plates.

[0009] Furthermore, connecting plates are fixedly connected to the bottom of the two side baffles on the side closest to each other, and the bottom of the two connecting plates abut against the top of the I-shaped plate. Springs are fixedly connected to the side of the two side connecting plates on the side furthest from each other, and the side of the springs furthest from each other is fixedly connected to the two sides inside the front installation compartment.

[0010] Furthermore, the front and rear sides of the I-shaped plate are slidably connected to the front and rear ends of the front installation compartment, respectively, and the bottom ends of the two upright plates abut against the bottom end of the front installation compartment.

[0011] Furthermore, a limiting plate is fixedly connected to the top of each of the two horizontal plates on the side furthest from each other, and the limiting plate is slidably connected to the side of the irregular plate furthest from each other on the side closest to each other.

[0012] Furthermore, the bottom ends of the irregular plates on both sides abut against the second limiting plate, and the front and rear ends of the second limiting plate are fixedly connected to the front and rear ends of the front installation compartment.

[0013] Furthermore, an opening is provided at the front of the front installation compartment, which is directly opposite the I-shaped plate.

[0014] Furthermore, the upper and lower ends of the threaded rod are rotatably connected to the upper and lower ends of the bracket, respectively, and the front and rear sides of the slider are slidably connected to the front and rear ends of the bracket, respectively.

[0015] The beneficial technical effects of this utility model are as follows:

[0016] 1. In this utility model, the speed sensor can be initially fixed by the I-shaped plate II, the horizontal plate, the irregular plate, the vertical plate, and the mounting ring, and then locked a second time by the I-shaped plate I, the rotating plate, and the baffle to effectively ensure the stability of the speed sensor during operation. Conversely, the speed sensor can be quickly unfixed by the reverse movement of the I-shaped plate I and the I-shaped plate II in the vertical direction, so that the speed sensor can be replaced and repaired in a timely manner. At the same time, the reverse movement of the I-shaped plate I and the I-shaped plate II can prevent the speed sensor from accidentally coming loose. In addition, the accuracy of the monitoring can be further improved by simultaneously monitoring the rotational speed of the vertical shaft and the main drive shaft.

[0017] 2. In this utility model, the speed sensor and related accessories can be transferred as a whole through the bracket, motor, threaded rod, and slider to ensure that the speed sensor can always effectively monitor the speed when the vertical shaft is rotating and moving downward, thereby increasing the working range of the vertical shaft and the speed sensor.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0029] Example 1

[0030] like Figure 1-2 , Figure 4-9As shown, this utility model provides a speed detection device for a vertical shaft drilling rig, including a drilling rig 1. An installation chamber 2 is provided on the lower front side and inside the drilling rig 1. An I-shaped plate 3 passes through the top of the front installation chamber 2. Rotary plates 4 are rotatably connected to both sides of the bottom end of the I-shaped plate 3. Baffles 5 are rotatably connected to the bottom ends of both rotating plates 4. An I-shaped plate 6 is provided below the baffles 5. Horizontal plates 7 are slidably connected to both sides of the lower part inside the front installation chamber 2. Irregularly shaped plates 8 are slidably connected to the opposite sides of the horizontal plates 7. Vertical plates 9 are slidably connected to the adjacent sides of the irregularly shaped plates 8. The tops of both vertical plates 9 are fixedly connected to the bottom end of the I-shaped plate 6. An installation ring 10 abuts against the adjacent side of the horizontal plates 7. A speed sensor 11 is fixedly connected inside the installation ring 10. Guide plates 12 are fixedly connected to both sides of the upper part inside the front installation chamber 2. The tops of both baffles 5 are slidably connected to the guide plates 12. At the bottom of plate 12, a connecting plate 13 is fixedly connected to the bottom of the two side baffles 5 on the side close to each other. The bottom of the two side connecting plates 13 abuts against the top of the I-shaped plate 6. A spring 14 is fixedly connected to the side of the two side connecting plates 13 away from each other. The side of the spring 14 away from each other is fixedly connected to the two sides inside the front installation chamber 2. The front and rear sides of the I-shaped plate 6 are slidably connected to the front and rear ends inside the front installation chamber 2. The bottom of the two side upright plates 9 abuts against the bottom of the front installation chamber 2. The top of the two side horizontal plates 7 is fixedly connected to the side away from each other. The side of the limit plate 15 close to each other is slidably connected to the side away from the irregular plate 8. The bottom of the two side irregular plates 8 abuts against the limit plate 16. The front and rear ends of the limit plate 16 are fixedly connected to the front and rear ends inside the front installation chamber 2. The front installation chamber 2 has an opening 17 at the front, which faces the I-shaped plate 6.

[0031] Specifically, when the speed sensor 11 needs to be replaced, pressing down on the I-shaped plate 3 with a finger will cause the rotating plate 4, which has a fixed length, to rotate. Then, under the guidance of the guide plate 12, the baffles 5 on both sides can be moved in opposite directions at the same time, and the connecting plate 13 connected to the baffles 5 will also move accordingly. After the baffles 5 and the connecting plate 13 have moved a certain distance, they will no longer block the I-shaped plate 6, thus releasing the restriction on the I-shaped plate 6.

[0032] At this time, another finger can be inserted into the installation chamber 2 through the opening 17, and the I-shaped plate 6 will move away from the baffle 5 and the connecting plate 13, leaving a notch to move upward along the installation chamber 2. As the I-shaped plate 6 moves upward, the vertical plate 9 can also move synchronously and separate from the installation chamber 2. During the upward movement along the horizontal plate 7, the T-shaped protrusion on the surface of the vertical plate 9 can slide along the matching T-shaped groove on the surface of the irregular plate 8 until the vertical plate 9 is completely separated from the horizontal plate 7. At this time, the T-shaped protrusion on the surface of the vertical plate 9 will also move to the uppermost part of the T-shaped groove on the surface of the irregular plate 8. At this time, as the I-shaped plate 6 continues to move the vertical plate 9... As the vertical plate 9 moves upward, the irregular plate 8 can also be moved upward along the horizontal plate 7 via the T-shaped protrusions on its surface. Simultaneously, since the irregular plate 8 and the horizontal plate 7 are in contact via an inclined surface, during the upward movement of the irregular plate 8, it can exert a horizontal thrust along the mounting chamber 2 on the horizontal plate 7 via the inclined surface. This allows the horizontal plates 7 to move away from each other through the space left by the vertical plate 9, thereby allowing the square protrusions on the surface of the horizontal plate 7 to leave the corresponding square cavity on the surface of the mounting ring 10. This achieves the purpose of eliminating the need for fixing the mounting ring 10 and the speed sensor 11, thus enabling timely replacement of the speed sensor 11. The internal mounting chamber 2 and the front mounting chamber 2 have the same internal components and structure. The internal mounting chamber 2 and the front mounting chamber 2 are used to monitor the rotational speeds of the main drive shaft and the vertical shaft, respectively, thus ensuring effective rotational speed monitoring of both the main drive shaft and the vertical shaft of the drilling rig 1.

[0033] After the speed sensor 11 is transferred through the cover at the bottom of the installation compartment 2, as the I-shaped plate 2 6 is released, gravity can be used to make the vertical plate 9 and the irregular plate 8 apply the fixing ring 10 and the speed sensor 11 to the horizontal plate 7 again, thereby actively completing the fixation. Furthermore, as the I-shaped plate 1 3 is released, the connecting plate 13, the baffle 5 and the rotating plate 4 can be restored to their initial positions by the spring 14. Thus, the connecting plate 13 and the installation compartment 2 limit the I-shaped plate 2 6 and the vertical plate 9, preventing the horizontal plate 7 from having space to move horizontally. In summary, the reverse movement of the I-shaped plate 1 3 and the I-shaped plate 2 6 in the vertical direction and the cooperation of related components can prevent the speed sensor 11 and the mounting ring 10 from accidentally coming loose, and the replacement of the speed sensor 11 is also relatively convenient.

[0034] Furthermore, when the irregular plate 8 moves upward with the vertical plate 9 and separates from the horizontal plate 7, its lower half can contact the limiting plate 15. The limiting plate 15 prevents the horizontal plate 7 from returning on its own, thus preventing the irregular plate 8 from being unable to re-enter the middle cavity of the horizontal plate 7 when it returns later. The limiting plate 2 16 can prevent the irregular plate 8 from moving downward excessively and can support the irregular plate 8, preventing the T-shaped protrusion at the connection between the irregular plate 8 and the vertical plate 9 from being subjected to excessive force. At the same time, the speed sensor 11 in the two mounting chambers 2 is in the same vertical plane as its corresponding main drive shaft and vertical shaft.

[0035] Example 2

[0036] like Figure 1 , Figure 3 As shown, a bracket 18 is fixedly connected to the lower front end of the drilling rig 1, and a motor 19 is fixedly connected to the top of the bracket 18. The output end of the motor 19 passes through the bracket 18 and is fixedly connected to a threaded rod 20. A slider 21 is threadedly connected to the outside of the threaded rod 20. The front end of the slider 21 is fixedly connected to the middle of the rear end of the front mounting chamber 2. The upper and lower ends of the threaded rod 20 are rotatably connected to the upper and lower ends inside the bracket 18, respectively. The front and rear sides of the slider 21 are slidably connected to the front and rear ends inside the bracket 18, respectively.

[0037] Specifically, the bracket 18 provides stable support for the motor 19, which in turn allows the threaded rod 20 to rotate inside the bracket 18. This, in conjunction with the guide groove on the surface of the bracket 18, enables the slider 21 to drive the mounting chamber 2, speed sensor 11, and other components to move up and down. This ensures that when the vertical shaft of the drilling rig 1 is working, the speed sensor 11 can move down appropriately with the vertical shaft under the drive of the slider 21, mounting chamber 2, and other related components, preventing the speed sensor 11 from detaching from the plane of the vertical shaft and thus failing to continue monitoring the rotational speed of the vertical shaft.

[0038] Working principle: In actual use, the downward pressing of I-shaped plate 3, in conjunction with rotating plate 4, baffle 5, and connecting plate 13, removes the restriction on the vertical displacement of I-shaped plate 6. Then, the upward movement of I-shaped plate 6 allows vertical plate 9 to detach from horizontal plate 7, thereby driving irregular plate 8 to move upward. At the same time, the inclined surface between irregular plate 8 and horizontal plate 7 allows the space left by horizontal plate 7 after vertical plate 9 moves away from mounting ring 10 and speed sensor 11, so that speed sensor 11 can be replaced in time if it is damaged due to harsh working environment. Since the replacement of speed sensor 11 requires I-shaped plate 3 and I-shaped plate 6 to move in opposite directions, it can prevent speed sensor 11 from accidentally falling off due to external factors, ensuring that speed sensor 11 can reliably monitor the speed of the main drive shaft and vertical shaft of drilling rig 1. In addition, through threaded rod 20, slider 21, and related components, speed sensor 11 can move downward with vertical shaft, preventing vertical shaft from falling out of the monitoring range of speed sensor 11 after being moved downward by the hydraulic system of drilling rig 1.

[0039] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. All contents not described in detail in the present invention can be derived from existing technology.
