Description

Technical Field

[0001] The utility model relates to the technical field of mine dredging tools, in particular to a mine dredging mechanical arm. Background Art

[0002] As the main transportation channel for mine ore, the chute plays a very important role in the mining process. Once the chute is blocked, it will seriously affect the normal production of the mine.

[0003] At present, the main methods for dealing with blockage in chute mines include mechanical prying, drilling and blasting, bamboo pole suspended charge blasting, hydrogen balloon suspended charge blasting and mining rockets. Among them, when using bamboo pole suspended charge blasting to dredge a blocked chute mine, the bamboo pole is used to carry explosives close to the blasting area. However, the bamboo pole itself cannot change its shape, and one end of the bamboo pole is extended into the chute mine from a fixed position, which makes it difficult to adjust the angle of the explosives installed on the bamboo pole, resulting in the problem that the explosives cannot be installed in the best blasting area, affecting the effect of blasting and dredging. Utility Model Content

[0004] The purpose of the utility model is to provide a mine chute dredging robot arm to solve the problem raised in the above-mentioned background technology that the bamboo pole itself cannot change its shape, and one end of the bamboo pole is extended into the mine chute from a fixed position, which makes it difficult to adjust the angle of the explosives installed on the bamboo pole, resulting in the problem that the explosives cannot be installed in the best blasting area, thus affecting the blasting and dredging effect.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mine dredging mechanical arm, comprising: a mounting seat;

[0006] A support arm is hinged on the mounting seat, a first telescopic member for adjusting the angle of the support arm is hinged between the support arm and the mounting seat, and a gripper for grabbing explosives is arranged on the end of the support arm.

[0007] Preferably, the support arm comprises a telescopic assembly hinged on a mounting seat and a reducer connected to the telescopic assembly.

[0008] Preferably, the telescopic assembly comprises a telescopic tube and a second telescopic member arranged in the telescopic tube.

[0009] Preferably, the mounting seat is connected to the fixed end of the telescopic tube via a first hinge.

[0010] Preferably, two ends of the first telescopic member are respectively connected to the mounting seat and the fixed end of the telescopic tube through a second hinge.

[0011] Preferably, the first telescopic member and the second telescopic member are one of an electric mast, a hydraulic telescopic rod or a pneumatic telescopic rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are: in the present application, the angle of the support arm is changed by telescoping the first telescopic member, so that the angle of the explosive on the gripper can be easily adjusted to ensure that the explosive is accurately installed in the blasting area, thereby improving the efficiency and quality of dredging the mine chute.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] See also Figure 1 A mine dredging mechanical arm comprises: a mounting base 1; a support arm 2 is hinged on the mounting base 1, a first telescopic member 3 (electric mast, hydraulic telescopic rod or pneumatic telescopic rod) is hinged between the support arm 2 and the mounting base 1, and a gripper 4 is provided on one end of the support arm 2 away from the mounting base 1.

[0019] Working principle: Fix the explosive to the gripper 4, then extend the mechanical arm into the ore chute, and through the extension of the first telescopic member 3, the arm 2 is rotated and changed in angle until the explosive on the gripper 4 contacts the blasting area, thereby fixing the explosive in the blasting area; then the gripper 4 releases the explosive and moves the mechanical arm out of the ore chute.

[0020] It should be noted that before installing the explosives, the internal situation of the chute is observed through a long-distance camera and a long-distance rangefinder to confirm the blockage position and height; and the mounting base 1 can be connected to a mobile device (such as a prying machine or other mobile device) to install the robotic arm on the mobile device for use, and the robotic arm can also be installed on a non-mobile device (that is, it can be installed in a fixed area for use).

[0021] It should also be noted that when the first telescopic member 3 rotates with the support arm 2 to change the angle, the support arm 2 can also be laid down to lower the height of the support arm 2 and the gripper 4 so that the robotic arm can enter and exit the chute; and the surface of the explosive is coated with adhesive to fix the explosive to the blasting area, so that during the blasting process, the robotic arm can be removed from the chute, so that the robotic arm can be reused to reduce costs; and the explosive is fixed in the blasting area, and no operator is required to support it, thereby increasing safety during the dredging of the chute.

[0022] In this embodiment, as a further optimized solution, please refer to Figure 2 The arm 2 includes a telescopic component 21 hinged on the mounting seat 1 and a reducer 22 connected to the telescopic component 21. The first telescopic member 3 is hinged to the mounting seat 1 and the fixed end of the telescopic component 21 respectively. When the blockage in the chute is high (after the arm 2 is in a vertical state, the explosives on the gripper 4 cannot contact the blasting area), the telescopic component 21 is extended to move the gripper 4 upward and install the explosives in the blasting area.

[0023] In this embodiment, as a further optimized solution, please refer to Figure 2 The telescopic assembly 21 includes a telescopic tube 212 and a second telescopic member 211 (electric mast, hydraulic telescopic rod or pneumatic telescopic rod) arranged in the telescopic tube 212. The two ends of the second telescopic member 211 are respectively connected to the fixed end and the movable end of the telescopic tube 212. The second telescopic member 211 is extended and retracted to change the length of the telescopic tube 212; one end of the first telescopic member 3 is connected to the mounting seat 1 through the second hinge 6, and the other end of the first telescopic member 3 is connected to the fixed end of the telescopic tube 212 through the second hinge 6, and the fixed end of the telescopic tube 212 is connected to the mounting seat 1 through the first hinge 5.

[0024] It should be noted that the first hinge 5 and the second hinge 6 are both composed of two connecting blocks, and the two connecting blocks are connected by a rotating shaft.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
