Description

Technical Field

[0001] This utility model relates to the field of mining equipment, specifically to a three-fold boom and a mine chute dredging device. Background Technology

[0002] As the main transportation channel for ore in mines, the ore pass plays a vital role in the mining process. Once the ore pass becomes blocked for any reason, it will seriously affect the normal operation of mine production. Currently, in the process of clearing ore passes, tools (such as telescopic rods) are generally used to push explosives to the bottom of the blocked ore pass and fix them in place. The explosives are then detonated to clear the ore pass. When clearing ore passes with high blockage areas, the telescopic rod needs to have a long stroke, which increases the length of the telescopic rod and makes it inconvenient to move and operate in confined spaces, thus posing certain limitations. Utility Model Content

[0003] The purpose of this utility model is to provide a three-fold boom and a mine chute dredging device, which solves the problems existing in the current telescopic boom for conveying explosive charges.

[0004] The present invention achieves the above objectives through the following technical solution: a three-fold boom, comprising: a base, a first arm, a second arm and a third arm connected in sequence, wherein the first arm, the second arm and the third arm are folded into a Z shape. The first arm is driven by a first drive member to pitch on the base, the second arm is driven by a second drive member to pitch on the first arm, and the third arm is driven by a rotating assembly to pitch and rotate on the second arm.

[0005] Preferably, the first support arm is hinged to the base, the first driving component is a hydraulic cylinder, and the two ends of the first driving component are respectively hinged to the first support arm and the base.

[0006] Preferably, the second arm is hinged to the end of the first arm, the second driving component is a hydraulic cylinder, and the two ends of the second driving component are respectively hinged to the first arm and the second arm.

[0007] Preferably, the rotating assembly includes a first swing cylinder, a mounting base disposed on the output end of the first swing cylinder, and a second swing cylinder disposed on the mounting base. The first swing cylinder is disposed on a second support arm, and the third support arm is disposed on the output end of the second swing cylinder.

[0008] Preferably, the output axis of the first swing cylinder is perpendicular to the output axis of the second swing cylinder.

[0009] Preferably, the first arm, the second arm, and the third arm are all telescopic arms.

[0010] Preferably, a mine chute dredging device includes: a vehicle body and a three-fold boom as described above, which is rotatably mounted on the vehicle body.

[0011] Preferably, the third arm is provided with a third swing cylinder, and the output end of the third swing cylinder is provided with a gripper.

[0012] The beneficial effects of this utility model are as follows: a three-fold boom is used to replace the traditional telescopic rod for transporting explosive charges. The three-fold boom, through its three-section folding structure design, can reduce its own volume and space occupation when stored, thus facilitating flexible movement and operation in the narrow mine chute working environment, and improving the overall convenience and work efficiency of mine chute dredging.

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0016] Example 1

[0017] Please see Figures 1-3 A three-folding boom includes: a base 1, a first arm 2, a second arm 4 and a third arm 6 connected in sequence, wherein the first arm 2, the second arm 4 and the third arm 6 are folded into a Z shape. The first arm 2 is driven by the first drive member 3 to pitch on the base 1, the second arm 4 is driven by the second drive member 5 to pitch on the first arm 2, and the third arm 6 is driven by the rotating assembly to pitch and rotate on the second arm 4.

[0018] In this embodiment, as a further optimization, please refer to... Figures 1-3 The first arm 2, the second arm 4, and the third arm 6 are all telescopic arms (capable of automatic extension and retraction, such as hydraulic cylinders). By extending the first arm 2, the second arm 4, and the third arm 6, the stroke of the three-stage folding assembly is increased, ensuring that the target object can be transported to the predetermined blasting area. At the same time, the first arm 2, the second arm 4, and the third arm 6 retract, reducing the volume of the three-stage folding assembly and minimizing its space occupation, making it easier for the three-folding boom to move and operate in confined spaces.

[0019] In this embodiment, as a further optimization, please refer to... Figures 1-3 A second driving element 5 (such as a hydraulic cylinder) is hinged between the moving end of the first arm 2 and the fixed end of the second arm 4 to drive the second arm 4 to rotate, so that the second arm 4 moves closer to or away from the first arm 2, thereby changing the pitch angle of the second arm 4.

[0020] In this embodiment, as a further optimization, please refer to... Figures 1-3 The rotating assembly includes a first swing cylinder 7, a mounting base 9 on the output end of the first swing cylinder 7, and a second swing cylinder 8 on the mounting base 9. The first swing cylinder 7 is mounted on the second support arm 4, and the third support arm 6 is mounted on the output end of the second swing cylinder 8. The first swing cylinder 7 drives the mounting base 9 to rotate the second swing cylinder 8 and the third support arm 6. The second swing cylinder 8 drives the third support arm 6 to rotate, so that the third support arm 6 can rotate to a vertical state. The output axis of the first swing cylinder 7 is perpendicular to the output axis of the second swing cylinder 8.

[0021] In this embodiment, as a further optimization, please refer to... Figures 1-3 The fixed end of the first arm 2 is hinged to the top wall of the base 1. A first driving component 3 (such as a hydraulic cylinder) is hinged between the top wall of the base 1 and the fixed end of the first arm 2 to drive the first arm 2 to rotate and change the pitch angle of the first arm 2. The base 1 is used to rotately connect with the equipment carrying the three-fold boom, which can be a mining vehicle.

[0022] Example 2

[0023] As a further optimization of Embodiment 1, a mine chute dredging device includes: a vehicle body, a three-fold boom mounted on the vehicle body, and a base 1 of the three-fold boom rotatably connected to the vehicle body, so that the vehicle body can move the three-fold boom in the mining area.

[0024] In this embodiment, as a further optimization, please refer to... Figures 1-3The third swing cylinder 10 is provided on the moving end of the third support arm 6, and the gripper 11 is provided on the output end of the third swing cylinder 10. The gripper 11 is used to grip the support member 12. The support member 12 is rod-shaped (such as a bamboo pole). An explosive charge 13 is placed on the support member 12. For example, the explosive charge 13 is tied to the outer wall of the support member 12. The gripper 11 is driven to swing by the third swing cylinder 10 to change the angle of the support member 12, so that the support member 12 can change from a state parallel to the third support arm 6 to a state perpendicular to the third support arm 6, so that the support member 12 can be placed horizontally inside the mine chute to fix the support member 12.

[0025] It should be noted that the gripper 11 is equipped with rollers, which are driven by a motor to rotate. The rotation of the rollers allows the support member 12 held by the gripper 11 to move, adjusting its position. By changing the angles of the first arm 2, the second arm 4, and the third arm 6, the support member 12 is transported below the blocked area of ​​the ore chute and placed laterally inside the ore chute, effectively fixing it and allowing the explosive charge 13 to approach the blocked area (see reference...). Figure 4 The flowcharts for the installation of the explosive charge 13 on the three-fold boom are as follows: Part a is a schematic diagram of the third arm 6 and the support 12 rotating to a vertical position below the blocked area of ​​the mine chute; Part b is a schematic diagram of the third swing cylinder 10 placing the support 12 horizontally below the blocked area of ​​the mine chute after the third arm 6 extends to drive the support 12 upward; Part c is a schematic diagram of the grab 11 releasing the support 12 and the third arm 6 retracting. Then, the grab 11 releases the support 12, the first arm 2, the second arm 4 and the third arm 6 retract and fold, and after being removed from the mine chute, the explosive charge is detonated to clear the mine chute.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
