Description

Technical Field

[0001] The utility model relates to the technical field of mine chute dredging, in particular to a secondary telescopic arm for mine chute 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 and even cause production to stop.

[0003] At present, the main methods for dealing with blockage in chute mines include mechanical prying method, drilling blasting method, bamboo pole cantilevered charge blasting method, hydrogen balloon suspended charge blasting method and mining rockets, etc. Among them, in the process of unblocking chute mines by using bamboo pole cantilevered charge blasting method and hydrogen balloon suspended charge blasting method, bamboo poles and hydrogen balloons are needed to help explosives approach the bottom of the ore blocking the chute mines, but this method cannot accurately control the position (the hydrogen balloon carries the explosives in an unfixed position and is easy to move; the bamboo pole cantilevered method is limited by the bamboo pole's inability to change shape and the bamboo pole's fixed entry method, which will cause the bamboo pole suspended explosives to be fixed in position), making it 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 two-stage telescopic arm for dredging a mine chute, so as to solve the problem that the method proposed in the above background technology cannot accurately control the position, making it difficult to install the explosives in the best position, thus affecting the blasting and dredging effect.

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

[0008] Preferably, the transverse telescopic member includes a first telescopic cylinder and a second telescopic member arranged in the first telescopic cylinder, and two ends of the second telescopic member are respectively connected to the fixed end and the movable end of the first telescopic cylinder.

DETAILED DESCRIPTION

[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 two-stage telescopic arm for dredging a mine chute comprises: a transverse telescopic member 1, a longitudinal telescopic member 2 and a first telescopic member 4; the fixed end of the transverse telescopic member 1 is connected to the fixed end of the longitudinal telescopic member 2 through a second hinge 6; one end of the first telescopic member 4 is connected to the fixed end side wall of the transverse telescopic member 1 through a first hinge 5, and the other end of the first telescopic member 4 is connected to the fixed end side wall of the longitudinal telescopic member 2 through a first hinge 5 (that is, the fixed end and the movable end of the first telescopic member 4 are respectively connected to the fixed ends of the transverse telescopic member 1 and the longitudinal telescopic member 2), and the first telescopic member 4 can be a cylinder, a hydraulic cylinder or an electric mast or other components; a gripper 3 is installed on the movable end of the longitudinal telescopic member 2.

[0019] See also Figure 2, the steps for dredging the chute are as follows:

[0020] 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);

[0021] The second step is to first pull out the baffle plate at the chute outlet during operation, clamp the explosive with the gripper 3, and fix the transverse telescopic member 1 at the chute outlet slot;

[0022] Step 3: The first telescopic member 4 is extended to rotate the longitudinal telescopic member 2 to change its angle, so that the longitudinal telescopic member 2 gradually tends to a horizontal state (gradually laying down the longitudinal telescopic member 2); then the transverse telescopic member 1 is extended to move the longitudinal telescopic member 2, so that the longitudinal telescopic member 2 passes through the lintel and enters the interior of the chute;

[0023] Step 4: The first telescopic member 4 is extended and retracted, so that the longitudinal telescopic member 2 rotates with the gripper 3, and the corresponding position of the gripper 3 is changed (so that the gripper 3 is aligned with the position where the bottom of the ore blocking the chute needs to be blasted). After completion, the first telescopic member 4 stops working;

[0024] It should be noted that in the fourth step, when the first telescopic member 4 is extended and retracted to change the angle of the gripper 3, the transverse telescopic member 1 can be extended and retracted to assist the gripper 3 in adjusting its position;

[0025] Step 5: The longitudinal telescopic member 2 is extended so that the explosive on the gripper 3 reaches the blocking position, and then the explosive can be adhered to the blocking ore;

[0026] Step 6: After the explosive is fixed, the gripper 3 releases the explosive, the longitudinal telescopic member 2 is shortened, and the first telescopic member 4 is extended, so that the longitudinal telescopic member 2 is rotated and laid flat; the transverse telescopic member 1 is contracted, so that the longitudinal telescopic member 2 is moved out of the ore chute;

[0027] Step 7: Detonate the explosives to resolve the blockage.

[0028] It should be noted that an adhesive layer is installed on the explosives to fix the explosives at the bottom of the ore blocking the chute, so that the secondary telescopic arm can be removed after the installation of the explosives is completed.

[0029] In this embodiment, as a further optimized solution, please refer to Figure 1The transverse telescopic member 1 includes a first telescopic cylinder 101 and a second telescopic member 102 arranged in the first telescopic cylinder 101, and the two ends of the second telescopic member 102 are respectively connected to the fixed end and the movable end of the first telescopic cylinder 101 (connected by a pin); the longitudinal telescopic member 2 includes a second telescopic cylinder 21 and a third telescopic member 22 arranged in the second telescopic cylinder 21, and the two ends of the third telescopic member 22 are respectively connected to the fixed end and the movable end of the second telescopic cylinder 21 (connected by a pin); wherein the second telescopic member 102 and the third telescopic member 22 can be components such as cylinders, hydraulic cylinders or electric masts.

[0030] In this embodiment, as a further optimized solution, please refer to Figure 1 The first telescopic cylinder 101 and the second telescopic cylinder 21 are both multi-stage telescopic cylinders.

[0031] In this embodiment, as a further optimized solution, please refer to Figure 1 The gripper 3 is detachably mounted on the moving end of the longitudinal telescopic member 2 (the gripper 3 can be connected to the moving end of the longitudinal telescopic member 2 by a threaded connector); the gripper 3 can be removed from the longitudinal telescopic member 2 and replaced.
