Description

Technical Field

[0001] The present invention relates to the field of mining machinery, and in particular to a mobile device for safely unblocking a mine chute. Background Art

[0002] Once a chute is blocked for some reason, it will seriously affect the normal operation of the mine and even cause production to stop. The current methods for dealing with chute blockage include mechanical prying, drilling and blasting, bamboo pole cantilevered explosive blasting, hydrogen balloon suspended explosive blasting, and mining rockets. These methods can effectively deal with chute blockage to a certain extent, but they still have significant safety risks and limitations.

[0003] In order to overcome the limitations of traditional dredging methods, a telescopic rod is generally used to push the explosives to the bottom of the ore blocking the chute, so that the explosives are close to the ore and then detonated; in the process of driving the telescopic rod to extend, the motor drives the reel to rotate, and the wire rope is reeled to pull the telescopic rod to extend (for example, the public document of a chute dredging jacking device with a locking function with the announcement number CN222795082U discloses such a device for driving the telescopic rod to extend); however, this device has certain limitations during use, and the motor is separated from the reel by the action of the clamping device, and there is a lack of automatic separation measures.

It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0038] Example 1

[0040] Working principle: Place the explosives on the explosives installation assembly. After the mobile device 1 moves to the predetermined area with the explosives, the second drive assembly drives the spline shaft 503 to rotate, causing the winding wheel 8 to rotate for winding the flexible connector 7, pulling the movable end of the telescopic rod 4 upward, lifting the telescopic rod 4, and after the top of the telescopic rod 4 contacts the blocked position, the first drive component drives the spline shaft 503 to move toward the inside of the rope reel body 501, so that the spline shaft 503 retracts and separates from the winding wheel 8; the mobile device 1 puts down the telescopic rod 4, and then the mobile device 1 withdraws from the working surface. After everyone reaches a safe position, the explosives are detonated to clear the remaining mine.

[0041] It should be noted that the second drive component can be a motor (the output shaft of the motor is directly slidably connected to the spline shaft 503, the spline shaft 503 can slide on the output shaft of the motor, and the motor can rotate with the spline shaft 503), or it can be composed of a motor and a gear set; the first drive component can be a telescopic drive member (such as a cylinder), or it can be composed of a telescopic drive member and a push plate.

A spring is installed between the block and the telescopic rod 4, and the end of the block extends between the teeth of the ratchet gear, restricting the ratchet gear so that the ratchet gear and the winding wheel 8 can only rotate in one direction, ensuring that the winding wheel 8 will not rotate in the opposite direction after the rope reel 5 is separated from the winding wheel 8; the telescopic rod 4 can be a two-stage telescopic rod or a multi-stage telescopic rod. Taking the two-stage telescopic rod as an example, the two-stage telescopic rod includes a fixed end and a movable end, and the movable end is slidably inserted in the fixed end. A guide member (such as a pulley) is provided on the top side wall of the movable end, and the end of the flexible connecting member 7 away from the winding wheel 8 bypasses the guide member and is connected to the bottom end of the movable end.

There is a protrusion on the side wall of the spline shaft 503, and the protrusion is located on the inner side of the fork 508.

[0047] It should be noted that the specific working method of the rope reel 5 is that the second motor 504 works to drive the driving gear 506 to rotate, which will drive the driven gear 507 to rotate together with the spline shaft 503, so that the winding wheel 8 rotates to wind the wire rope, pull the movable end of the telescopic rod 4 upward, lift the telescopic rod 4, and after the top of the telescopic rod 4 contacts the blocking position, the second motor 504 stops working; the driving member 505 works and extends, causing the fork 508 to rotate, and one end of the fork 508 presses on the raised part of the spline shaft 503, pushing the spline shaft 503 toward the inside of the rope reel body 501, so that the spline shaft 503 is retracted and separated from the winding wheel 8.
