Description

Technical Field

[0001] This utility model relates to the field of mine trolley technology, specifically a wirelessly remote-controlled, battery-powered mine trolley device. Background Technology

[0002] There are two modes of transportation in mines: trackless transportation and rail transportation. Rail transportation is more commonly used for vertical shaft hoisting.

[0003] Traditional rail transport combines overhead electric locomotives with manual carts. Mine gate filling is mostly done manually, while roadway transport uses overhead electric locomotives. Manual cart handling is labor-intensive and requires multiple people to work together. Overhead electric locomotives require overhead lines and silicon rectifiers to provide power. In short-distance transport, they have disadvantages such as occupying personnel and high maintenance costs. In addition, the traditional connection structure for mine carts is complex and the docking process is cumbersome, requiring a lot of time and manpower for alignment and fixing, which seriously affects the progress of cart filling. To address this, we propose a wirelessly remote-controlled, battery-powered mine cart device. Utility Model Content

[0060] Working Principle: The wireless remote-controlled, battery-powered mine trolley device is correctly installed according to the diagram. During operation, eight 3-EVE-200 lead-acid maintenance-free batteries 5 serve as the power source, providing stable power to the entire system. The operator holds an F21-E1B wireless industrial remote control and sends a control signal within a 100-meter unobstructed range. The wireless industrial remote control receiver module 6 receives the signal and transmits the command to the Curtis DC series motor speed controller 4. The Curtis DC series motor speed controller 4, as the core control system, precisely regulates the operation of the DC motor 7 (model ZQ-4-442V 3.5KW) according to the command, thereby driving the trolley device body 1. When connecting a mine car, the operator controls the clamping motor 8 to rotate via the remote control. The limiting block 17 in the middle section of the output shaft of the clamping motor 8 cooperates with the axial limiting cavity 12 to ensure stable rotation of the output shaft. Because its output shaft corresponds to the limiting block 1... The two threaded rods on the two shafts rotate in opposite directions. When rotated, they drive the sliders 20 of the two clamping parts 9 to retract into the slide groove 15. Then, the trolley device body 1 is operated so that the frustum-shaped connecting groove 16 on the connecting box 2 aligns with the frustum-shaped plug 23 of the connecting block 3. The frustum structure facilitates alignment, improving the alignment efficiency. After alignment, the clamping motor 8 is controlled to rotate in the opposite direction. The sliders 20 of the two clamping parts 9 move relative to each other under the threaded engagement of the threaded bushing 19 and the output shaft of the clamping motor 8. The arc-shaped opening 21 on the slider 20 engages with the fixing groove 24 on the side wall of the plug 23 of the connecting block 3, firmly fixing the connecting block 3. The sleeve 18 on the clamping part 9 slides with the guide rod 14 to ensure a smooth clamping process and prevent the clamping part 9 from deflecting or shaking. After the connection is completed, the trolley can be filled by wireless remote control. The entire process does not require close contact by the operator, improving the safety and convenience of operation.

[0061] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
