Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining machinery, specifically to a double-section boom and a mine chute clearing device. Background Technology
[0002] A mine chute is a tunnel through which ore flows downwards under its own weight. Blockages in mine chutes can severely impact mine operations. Current methods for dealing with mine chute blockages include mechanical prying, drilling and blasting, using bamboo poles to suspend explosive charges for blasting, using hydrogen balloons to suspend explosive charges for blasting, and mining rockets.
[0003] For the bamboo pole suspended explosive charge blasting method, an unmanned transport vehicle with a mechanical gripper mechanism is often used to transport the explosive to a suitable blasting location. For example, in the safety unblocking mobile device for mine chute disclosed in application number 202510866337.9, after the unmanned transport vehicle arrives at the location, it uses a gripper mechanism to clamp the telescopic rod and fix the explosive at the top of the telescopic rod, thereby moving the explosive to the blasting location for blasting. The gripper mechanism of the above-mentioned unblocking device lacks a flexible multi-angle mechanical arm, making it difficult to adapt to complex throwing angles when throwing explosives. Utility Model Content
[0004] The purpose of this utility model is to provide a double-section boom and a mine chute dredging device, which solves the problem that existing dredging devices lack multi-angle flexible robotic arms.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] A double-section boom includes a boom assembly, a forearm assembly, and a gripper mechanism. The forearm assembly is located at the end of the boom assembly, and both the boom assembly and the forearm assembly are provided with a pitch adjustment structure that rotates along a horizontal axis and a slewing adjustment structure that rotates along a vertical axis.
[0007] The pitch adjustment structure of the forearm assembly includes a first tilting platform mounted on the boom assembly, and the rotation adjustment structure of the forearm assembly includes a second rotation platform mounted on the first tilting platform. The forearm assembly is mounted on the second rotation platform. This solution controls the pitch and rotation adjustment of the forearm assembly by setting the first tilting platform and the second rotation platform. The second rotation platform allows the forearm assembly to rotate above the boom assembly when not in use, which helps to reduce the space occupied in the length direction.
[0008] As a preferred embodiment of this utility model, the slewing adjustment structure of the boom assembly includes a first slewing platform, and the pitch adjustment structure includes a hydraulic cylinder. One end of the boom assembly is hinged to the first slewing platform, one end of the hydraulic cylinder is hinged to the first slewing platform, and the other end is hinged to the boom assembly. This embodiment drives the boom assembly to perform slewing and pitch adjustments by setting the first slewing platform and the hydraulic cylinder.
[0009] As a preferred embodiment of this utility model, the rotation angle of the first rotary platform is 0-360°.
[0010] As a preferred embodiment of the present invention, the non-hinged end of the boom assembly is provided with an extension arm, and the first flipping platform is provided on the extension arm. This embodiment further provides an extension arm on the boom assembly, which is used to extend the length of the boom assembly. It can be telescopically set, and the end of the extension arm is used to install the forearm assembly.
[0011] As a preferred embodiment of this utility model, the flipping angle of the first flipping platform is 0-180°, and the rotation angle of the second rotating platform is 0-90°.
[0012] As a preferred embodiment of this utility model, the forearm assembly is a telescopic arm, and a second flipping platform is provided on its end arm segment. This embodiment makes the gripper mechanism more flexible by setting the forearm assembly as a telescopic arm and providing a second flipping platform at its end.
[0013] As a preferred embodiment of this utility model, the flipping angle of the second flipping platform is 0-90°.
[0014] In order to apply the above-mentioned double-section boom for dredging mine chutes, this utility model also proposes a mine chutes dredging device, including a transport vehicle, on which a double-section boom as described above is provided, and a gripper mechanism is provided at the end of the boom assembly of the double-section boom.
[0015] The beneficial effects of this utility model are as follows: By setting up a boom assembly and a forearm assembly with rotation and pitch functions, this utility model enables the boom to have sufficient length and flexible directional adjustment capabilities. The two-dimensional pitch adjustment function allows the boom and forearm to be combined to form a suitable angle to avoid obstacles, and the two-directional rotation allows the boom and forearm to be folded by rotation, which facilitates the movement of the transport vehicle.

[0021] 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.
[0022] Example
[0023] like Figure 1-4 As shown, a double-section boom includes a boom assembly 2, a forearm assembly 6, and a gripper mechanism 8. The forearm assembly 6 is located at the end of the boom assembly 2, and both the boom assembly 2 and the forearm assembly 6 are provided with a pitch adjustment structure that rotates along a horizontal axis and a slewing adjustment structure that rotates along a vertical axis.
[0024] The pitch adjustment structure of the forearm assembly 6 includes a first tilting platform 4 mounted on the boom assembly 2, and the slewing adjustment structure of the forearm assembly 6 includes a second slewing platform 5 mounted on the first tilting platform 4. The forearm assembly 6 is mounted on the second slewing platform 5. This solution controls the pitch and slewing adjustment of the forearm assembly 6 by setting the first tilting platform 4 and the second slewing platform 5. The second slewing platform 5 allows the forearm assembly 6 to rotate above the boom assembly 2 when not in use, which helps to reduce the space occupied in the length direction.
[0025] This solution incorporates a boom assembly 2 with slewing and pitching functions, and a forearm assembly 6, which provide the boom with sufficient length and flexible directional adjustment capabilities. The two-dimensional pitching adjustment allows the boom and forearm to be combined at a suitable angle to avoid obstacles, while the two-directional slewing allows the boom and forearm to be folded for easy movement by the transport vehicle.
[0026] Preferably, the slewing adjustment structure of the boom assembly 2 includes a first slewing platform 1, and the pitch adjustment structure includes a hydraulic cylinder 9. One end of the boom assembly 2 is hinged to the first slewing platform 1, and one end of the hydraulic cylinder 9 is hinged to the first slewing platform 1, while the other end is hinged to the boom assembly 2. This solution drives the boom assembly 2 to perform slewing and pitch adjustments by setting the first slewing platform 1 and the hydraulic cylinder 9.
[0027] Please see Figure 2In use, the first slewing platform 1 orients the boom assembly 2 at a suitable angle, the hydraulic cylinder 9 operates to adjust the pitch angle of the boom assembly 2, and then the second slewing platform 5 rotates along its axis, causing the forearm assembly 6 to rotate to a direction away from the gripper mechanism 8 from the first slewing platform 1, so as to strengthen the overall length of the boom.
[0028] Preferably, the non-hinged end of the boom assembly 2 is provided with an extension arm 3, and the first tilting platform 4 is provided on the extension arm 3. This solution further provides an extension arm 3 on the boom assembly 2. The extension arm 3 is used to extend the length of the boom assembly 2. It can be telescopically set, and the end of the extension arm 3 is used to install the forearm assembly 6.
[0029] Preferably, the forearm assembly 6 is a telescopic arm, and a second flipping platform 7 is provided on its end arm segment. This solution makes the gripper mechanism 8 more flexible by setting the forearm assembly 6 as a telescopic arm and providing a second flipping platform 7 at its end.
[0030] Please see Figure 2-4 Optionally, the rotation angle of the first rotating platform 1 is 0-360°, and it can rotate to any angle along the vertical axis; the tilting angle of the first tilting platform 4 is 0-180°, and the first tilting platform 4 can rotate from vertically downward (i.e., Figure 2 The orientation in the viewpoint is flipped to vertical downwards; the rotation angle of the second rotating platform 5 is 0-90°. Figure 2 The forearm assembly 6 and the upper arm assembly 2 are parallel. The rotation angle allows the forearm assembly 6 to rotate 45° to the left and right relative to the upper arm assembly 2. The second flipping platform 7 has a flipping angle of 0-90° and is used to adjust the orientation of the gripper mechanism 8. It can be selected to adjust the pitch angle up and down by 45° relative to the forearm assembly 6.
[0031] In order to apply the above-mentioned double-section boom for dredging mine chutes, this utility model also proposes a mine chutes dredging device, including a transport vehicle, on which a double-section boom as described above is provided, and a gripper mechanism 8 is provided at the end of the boom assembly 6 of the double-section boom.
[0032] The explosive is fixed to the top of the telescopic boom, and then the telescopic boom is secured using the gripper mechanism 8. The double-section boom is... Figure 2 The folded state shown indicates that the vehicle moves towards the blasting position. When the transport vehicle reaches the appropriate position, it is parked and fixed. If necessary, reinforcement and support are provided. Then, the angle and orientation of the boom assembly 2 are adjusted first through the first rotating platform 1 and the hydraulic cylinder 9. Then, the angle and orientation of the forearm assembly 6 are adjusted through the first tilting platform 4 and the second rotating platform 5. Then, the forearm assembly 6 extends. The angle of the grab mechanism 8 is controlled by the second tilting platform 7, so that the top of the telescopic rod reaches the appropriate blasting position after it extends.
[0033] 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.
