Description

Technical Field

[0001] The utility model relates to the technical field of mine dredging, in particular to a vehicle-mounted secondary telescopic arm for mine dredging. 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 for some reason, it will seriously affect the normal production of the mine.

[0003] At present, the main methods for dealing with blockage in chute include mechanical prying, drilling and blasting, bamboo pole suspended charge blasting, hydrogen balloon suspended charge blasting and mining rockets. Although these methods can effectively deal with chute blockage to a certain extent, they still have great safety risks and limitations. For example, in the process of unblocking chute by bamboo pole suspended charge blasting and hydrogen balloon suspended charge blasting, bamboo poles and hydrogen balloons are needed to help the explosives approach the bottom of the ore blocking the chute. However, this method cannot accurately control the installation position of the explosives (the hydrogen balloon moves with the explosives, and the explosives are not fixed, so they are easy to move; the bamboo pole suspension method is limited by the bamboo pole's inability to change shape, which will cause the bamboo pole suspended explosive position to be fixed, and the bamboo pole needs to be manually held, which poses a safety hazard). It will be difficult to install the explosives in the best position, affecting the effect of blasting and unblocking. Utility Model Content

[0004] The utility model aims to provide a vehicle-mounted two-stage telescopic arm for dredging a mine chute, so as to solve the problem that the method proposed in the above-mentioned background technology cannot accurately control the installation position of the explosives, which makes it difficult to install the explosives in the best position, thus affecting the blasting and dredging effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vehicle-mounted two-stage telescopic arm for dredging a mine chute, comprising: a vehicle body;

[0006] A transverse telescopic member is hinged on the vehicle body, a second telescopic member is hinged between the vehicle body and the transverse telescopic member, a longitudinal telescopic member is hinged on the movable end of the transverse telescopic member, and a first telescopic member is hinged between the movable end side wall of the transverse telescopic member and the fixed end side wall of the longitudinal telescopic member;

[0007] A gripper for grabbing explosives is provided on the moving end of the longitudinal telescopic member.

[0008] Preferably, a rotating assembly is provided on the top of the vehicle body, and the transverse telescopic member and the second telescopic member are both mounted on the rotating assembly.

[0009] Preferably, the rotating assembly comprises a turntable rotatably mounted on the top of the vehicle body and a driving member for driving the turntable to rotate, and the transverse telescopic member and the second telescopic member are both mounted on the turntable.

[0010] Preferably, the gripper is detachably mounted on the movable end of the longitudinal telescopic member.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: in the present application, the vehicle body is used to support the secondary telescopic arm during operation, and the first telescopic part and the lateral telescopic part are extended and retracted to accurately adjust the position of the gripper, so that the explosives can be more accurately installed at the blocked position of the chute, thereby improving the accuracy of blasting and greatly improving the success rate of clearing the blockage.

[0015] 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.

[0016] Example 1

[0017] See also Figure 1 A vehicle-mounted two-stage telescopic arm for dredging a mine chute comprises: a body 1 and a transverse telescopic member 3; the top of the body 1 is hinged to the fixed end of the transverse telescopic member 3, a second telescopic member 7 is hinged between the top of the body 1 and the fixed end side wall of the transverse telescopic member 3 (the body 1 and the second telescopic member 7 are hinged, and the transverse telescopic member 3 and the second telescopic member 7 are also hinged), a longitudinal telescopic member 4 is hinged on the moving end of the transverse telescopic member 3, a first telescopic member 6 is hinged between the moving end side wall of the transverse telescopic member 3 and the fixed end side wall of the longitudinal telescopic member 4; a gripper 5 is provided on the moving end of the longitudinal telescopic member 4 (the transverse telescopic member 3, the longitudinal telescopic member 4, the gripper 5 and the first telescopic member 6 constitute a two-stage telescopic arm).

[0018] It should be noted that the first telescopic member 6 and the second telescopic member 7 can be cylinders, hydraulic cylinders or electric masts; and the transverse telescopic member 3 and the longitudinal telescopic member 4 can also be cylinders, hydraulic cylinders or electric masts; the second telescopic member 7 can change the pitch angle of the transverse telescopic member 3 by telescoping.

[0019] In this implementation, as a further optimization solution, please refer to Figure 1 The gripper 5 can be detachably mounted on the moving end of the longitudinal telescopic member 4; (the gripper 5 can be connected to the moving end of the longitudinal telescopic member 4 by a threaded connector); the gripper 5 can be removed from the longitudinal telescopic member 4 and replaced.

[0020] See also Figure 2 , a method for dredging a mine chute comprises the following steps:

[0021] The first step is to observe the internal situation through the camera and rangefinder (to determine the blockage inside the chute), and select the appropriate telescopic arm (that is, select the secondary telescopic arm);

[0022] Step 2: When working, first move the vehicle body 1 to the exit of the chute, and use the gripper 5 to clamp the explosives;

[0023] Step 3: The second telescopic member 7 is extended to gradually level the transverse telescopic member 3, and at the same time, the first telescopic member 6 is extended to rotate the longitudinal telescopic member 4 to change the angle, so that the longitudinal telescopic member 4 gradually tends to a horizontal state (gradually laying down the longitudinal telescopic member 4); then the transverse telescopic member 3 is extended to move the longitudinal telescopic member 4 and enter the interior of the chute through the lintel;

[0024] Step 4: The first telescopic member 6 is extended and retracted, so that the longitudinal telescopic member 4 rotates with the gripper 5, and the corresponding position of the gripper 5 is changed (so that the gripper 5 faces the position at the bottom of the ore blocking the chute that needs to be blasted). After completion, the first telescopic member 6 stops working;

[0025] It should be noted that in the fourth step, when the first telescopic member 6 is extended and retracted to change the angle of the gripper 5, the transverse telescopic member 3 can be extended and retracted to assist the gripper 5 in adjusting its position;

[0026] Step 5: The longitudinal telescopic member 4 is extended to move the gripper 5 upward, bringing the explosive to the blocking position, and then the explosive can be adhered to the bottom of the blocking ore;

[0027] Step 6: After the explosive is fixed, the gripper 5 releases the explosive, the longitudinal telescopic member 4 shortens, and the first telescopic member 6 lengthens, so that the longitudinal telescopic member 4 rotates and lies flat; the transverse telescopic member 3 contracts, so that the longitudinal telescopic member 4 moves out of the ore chute;

[0028] Step 7: After moving the vehicle body 1 out of the ore chute exit, detonate the explosives to resolve the blockage.

[0029] It should be noted that an adhesive layer is installed on the explosives to fix the explosives to the bottom of the ore blocking the chute, so that the vehicle-mounted secondary telescopic arm can be removed after the installation of the explosives is completed; and the adhesive layer can also be replaced with other fixings to fix the explosives to the bottom of the ore.

[0030] In this embodiment, as a further optimized solution, please refer to Figure 1 , a rotating assembly 2 is provided on the top of the vehicle body 1;

[0031] Among them, see Figure 1 The rotating assembly 2 includes a turntable 21 and a driving member 22. The turntable 21 is rotatably mounted on the top of the vehicle body 1. The driving member 22 is mounted on the top of the vehicle body 1 and is used to drive the turntable 21 to rotate. The transverse telescopic member 3 and the second telescopic member 7 are both mounted on the turntable 21. The driving member 22 drives the turntable 21 to rotate, which can drive the transverse telescopic member 3 and the second telescopic member 7 to rotate to adjust their positions.

[0032] It should be noted that the connection between the transverse telescopic member 3, the second telescopic member 7 and the turntable 21 can be disconnected, so that the transverse telescopic member 3 and the longitudinal telescopic member 4 and other components can be better.

[0033] In this embodiment, as a further optimized solution, please refer to Figure 1 The transverse telescopic member 3 and the longitudinal telescopic member 4 both include a telescopic cylinder and a telescopic assembly arranged in the telescopic cylinder, and the two ends of the telescopic assembly are respectively connected to the fixed end and the movable end of the telescopic cylinder (connected by a pin shaft); the telescopic cylinder is a multi-stage telescopic cylinder; wherein the telescopic assembly is one of a cylinder, a hydraulic cylinder or an electric mast.
