Description

Technical Field

[0001] This invention relates to the field of open-pit mining technology, specifically to a tracking and measuring device for the rotation angle of an electric shovel arm in an open-pit mine. Background Technology

[0002] Open-pit electric shovels are large-scale and highly efficient equipment, and are one of the hallmarks of modern mines. However, open-pit electric shovels are generally large in size, so during operation, they often collide with each other, posing safety hazards to the production process. Therefore, knowing the angle of rotation of the equipment can help avoid collisions caused by the rotating electric shovel. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a tracking and measuring device for the rotation angle of the arm of an open-pit mine electric shovel. This device solves the problem that open-pit mine electric shovels are generally large in size, which often leads to collisions between the shovel and other equipment during operation, posing a safety hazard to the production process.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a tracking and measuring device for the rotation angle of an electric shovel arm in an open-pit mine, comprising a bottom support plate, a connecting rod fixedly connected to one side of the top of the bottom support plate, a first bearing sleeved on the outer wall of the connecting rod, a convex rotating cylinder sleeved on the outer wall of the first bearing, a rubber ring sleeved on the outer wall of the convex rotating cylinder near the top support plate, a first gear sleeved on the outer wall of the convex rotating cylinder near the connecting rod, a fixing post fixedly connected to the bottom of the top support plate away from the connecting rod, a second bearing sleeved on the outer wall of the fixing post, a second gear fixedly connected to the bottom of the outer wall of the second bearing, a mileage measuring instrument fixedly installed on the top of the top support plate away from the connecting rod, and a sensor fixedly connected to the bottom of the top support plate away from the connecting rod, the bottom of the sensor being fixedly connected to the bottom support plate away from the connecting rod.

[0005] Preferably, the outer wall of the second gear meshes with the outer wall of the first gear.

[0006] Preferably, the output terminal of the odometer is connected to the input terminal of the sensor, and the output signal of the sensor is connected to a display.

[0007] Preferably, an L-shaped support plate is slidably connected to the bottom of the bottom support plate, and a limiting sliding rod is sleeved on the side of the L-shaped support plate away from the connecting plate. One end of the limiting sliding rod is fixedly connected to the side of the connecting plate away from the connecting rod, and a limiting plate is fixedly connected to the other end of the limiting sliding rod. A spring is sleeved on the outer wall of the limiting sliding rod.

[0008] Preferably, a slider is fixedly connected to the bottom of the bottom support plate, and a groove is provided on the inner wall of the bottom of the L-shaped support plate. The slider fixedly connected to the bottom of the bottom support plate is placed in the groove provided on the inner wall of the bottom of the L-shaped support plate.

[0009] Preferably, the two ends of the spring are fixedly connected to the side of the L-shaped support plate away from the connecting plate and the side of the connecting plate away from the connecting rod. The end of the limiting sliding rod away from the connecting plate passes through the side of the L-shaped support plate away from the connecting plate and extends to the outside of the L-shaped support plate and is fixedly connected to the limiting plate.

[0010] Beneficial effects This invention provides a tracking and measuring device for the rotation angle of the boom of an electric shovel in an open-pit mine. Compared with the prior art, it has the following advantages: 1. The tracking and measuring device for the rotation angle of the electric shovel arm in this open-pit mine first makes contact with the rotating part of the electric shovel arm through a rubber ring, which then enables the convex rotating drum to rotate. The outer wall of the first gear meshes with the outer wall of the second gear, thereby effectively realizing the rotation of the second bearing. The odometer can then measure the distance the electric shovel arm rotates, making it easy to calculate the angle and effectively preventing the electric shovel from rotating and colliding.

[0011] 2. The tracking and measuring device for the rotation angle of the electric shovel arm in the open-pit mine is fixed by an L-shaped support plate. This allows the sliding groove on the inner wall of the bottom of the L-shaped support plate to limit the slider fixed to the bottom of the support plate. In addition, the spring can effectively compress the connecting plate, thus achieving a tighter contact between the rubber ring and the electric shovel arm. This avoids the problem of poor contact caused by the rubber ring being fixed in one position and wearing out. Attached Figure Description

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figure 1 , Figure 2 , Figure 3 This invention provides a technical solution: a tracking and measuring device for the rotation angle of an electric shovel arm in an open-pit mine, comprising a bottom support plate 1, a connecting rod 2 fixedly connected to one side of the top of the bottom support plate 1, a first bearing 7 sleeved on the outer wall of the connecting rod 2, a convex rotating cylinder 4 sleeved on the outer wall of the first bearing 7, a rubber ring 5 sleeved on the outer wall of the convex rotating cylinder 4 near the top support plate 3, a first gear 6 sleeved on the outer wall of the convex rotating cylinder 4 near the connecting rod 2, a fixing post 8 fixedly connected to the bottom of the top support plate 3 away from the connecting rod 2, a second bearing 9 sleeved on the outer wall of the fixing post 8, a second gear 10 fixedly connected to the bottom of the outer wall of the second bearing 9, a mileage measuring instrument 11 fixedly installed on the top of the top support plate 3 away from the connecting rod 2, and a sensor 12 fixedly connected to the bottom of the top support plate 3 away from the connecting rod 2, the bottom of the sensor 12 being fixedly connected to the bottom support plate 1 away from the connecting rod 2.

[0016] The outer wall of the second gear 10 meshes with the outer wall of the first gear 6. The output end of the odometer 11 is connected to the input end of the sensor 12, and the output signal of the sensor 12 is connected to a display.

[0017] Please see Figure 1 , Figure 2 The bottom of the bottom support plate 1 is slidably connected to an L-shaped support plate 14. A limiting sliding rod 15 is sleeved on the side of the L-shaped support plate 14 away from the connecting plate 13. One end of the limiting sliding rod 15 is fixedly connected to the side of the connecting plate 13 away from the connecting rod 2. The other end of the limiting sliding rod 15 is fixedly connected to a limiting plate 17. A spring 16 is sleeved on the outer wall of the limiting sliding rod 15.

[0018] A slider is fixedly connected to the bottom of the bottom support plate 1. A groove is provided on the inner wall of the bottom of the L-shaped support plate 14. The slider fixedly connected to the bottom of the bottom support plate 1 is placed in the groove provided on the inner wall of the bottom of the L-shaped support plate 14. The two ends of the spring 16 are fixedly connected to the side of the L-shaped support plate 14 away from the connecting plate 13 and the side of the connecting plate 13 away from the connecting rod 2. The end of the limiting sliding rod 15 away from the connecting plate 13 passes through the side of the L-shaped support plate 14 away from the connecting plate 13 and extends to the outside of the L-shaped support plate 14 and is fixedly connected to the limiting plate 17.

[0019] In use, the bottom support plate 1 is first installed on the electric shovel arm, and the rubber ring 5 is in contact with the rotating part of the electric shovel arm. Because the bottom support plate 1 and the top support plate 3 can support the connecting rod 2, and the first bearing 7 sleeved on the outer wall of the connecting rod 2 can facilitate the rotation of the convex rotating cylinder 4. When the electric shovel arm rotates, the friction of the rubber ring 5 can drive the convex rotating cylinder 4 to rotate, which in turn enables the convex rotating cylinder 4 to drive the first gear 6 to rotate. Because the outer wall of the first gear 6 meshes with the outer wall of the second gear 10, the rotation of the first gear 6 can effectively drive the rotation of the second gear 10. Because the second bearing 9 is supported by the fixed post 8, the second bearing 9 can rotate. The odometer 11 can calculate the number of rotations of the second bearing 9 and record the number of kilometers rotated. The information can be transmitted to the sensor 12, and the sensor 12 can transmit the information to the display, thus effectively enabling the measurement of the rotation angle of the electric shovel arm. The bottom of the bottom support plate 1 is slidably connected to the bottom inner wall of the L-shaped support plate 14, and the slider fixed at the bottom of the bottom of the bottom support plate 1 is placed in the groove opened at the bottom inner wall of the L-shaped support plate 14. This effectively limits the slider fixed at the bottom of the bottom of the bottom support plate 14 by the groove opened at the bottom of the L-shaped support plate 14. The limiting sliding rod 15 can also support and limit the connecting plate 13. By installing the L-shaped support plate 14 on the electric shovel arm, the connecting plate 13 can be effectively squeezed by the tension of the spring 16. Therefore, the connecting plate 13 can drive the bottom support plate 1 and the top support plate 3 to squeeze the connecting rod 2, thereby effectively making the rubber ring 5 more firmly in contact with the rotating part of the electric shovel arm and avoiding the problem of the rubber ring 5 not rotating.
