[0026] In order to keep the following description of the embodiments of the present invention clear and concise, the detailed description of known functions and known components is omitted in the present invention.

[0027] Embodiment 1

[0028] Please refer to Figures 1-4 , the anti-reversal device for inclined roadway monkey cars, which is applied in the field of inclined roadway monkey cars and includes:

[0029] A bracket 1, the bracket 1 serves as the basic support structure of the entire device, on one side of which a supporting wheel 3 is rotatably installed, a steel wire rope 4 passes through the wheel rail of the supporting wheel 3, and a connecting rod 5 of the personnel riding frame is slidably connected to the steel wire rope 4 for connecting the monkey car to carry and transport personnel. A through hole 6 is also provided on the bracket 1 for installing the anti-reversal component;

[0030] In order to enhance the installation stability of the bracket 1, a ceiling mounting bracket 2 is fixedly provided on the top of the bracket 1, and reserved mounting holes are provided at the four corners of the ceiling mounting bracket 2 to facilitate its firm installation on the top of the mine roadway or other suitable positions through fasteners such as bolts;

[0031] The anti-reversal component is installed on the bracket 1 and is used to prevent casualties caused by the reverse movement of the connecting rod 5 of the personnel riding frame. The anti-reversal component includes a screw rod 7 passing through the through hole 6. One end of the screw rod 7 is fixedly provided with a round rod 9. The round rod 9 serves as a support and a rotation center to ensure that the sleeve 8 can freely rotate around it. The other end of the screw rod 7 is tightened with a nut 10 to fix the entire anti-reversal component. A sleeve 8 is rotatably installed on the round rod 9. The bottom of the outer wall of the sleeve 8 is fixedly provided with an L-shaped flap 12. The design of the L-shaped flap 12 enables the corner of it to catch the side wall of the bracket 1, so that the L-shaped flap 12 can be flipped upward and cannot be flipped downward;

[0032] A blocking member 13 is fixedly provided at the edge of the bottom of the L-shaped flap 12. When the connecting rod 5 of the personnel riding frame moves upward, it can smoothly pass over the blocking member 13. When moving downward, the connecting rod 5 of the personnel riding frame is blocked by the blocking member 13, so as to prevent its continuous movement by physical blocking, thus avoiding accidents.

[0033] Embodiment 2

[0034] Based on Embodiment 1, the improvement is as follows:

[0035] Please refer to Figures 3-4 , in order to improve the fixing effect, an anti-slip pad 11 is sleeved between the nut 10 and the bracket 1 to prevent potential safety hazards caused by vibration or loosening. In addition, the integral workpiece formed by the sleeve 8, the L-shaped flap 12 and the blocking member 13 is quenched to enhance the hardness, which not only enhances the wear resistance and impact resistance of these components, but also improves the service life and reliability of the entire anti-reversal component.

[0036] The working principle and usage process of this technical solution are as follows:

[0037] During normal transportation, the connecting rod 5 of the personnel riding frame slides on the wheel rail of the supporting wheel 3 through the steel wire rope 4, driving the riding frame to move upward along the inclined lane. At this time, the anti-reversal component is in a non-working state, and the L-shaped flap 12 and the blocking member 13 thereon will flip upward and will not obstruct the connecting rod 5 of the riding frame. When the connecting rod 5 of the personnel riding frame shows a reverse trend due to faults, operation errors or other reasons, the anti-reversal component responds quickly. When the connecting rod 5 of the riding frame attempts to reverse, it will contact the blocking member 13 at the bottom of the L-shaped flap 12. Due to the design and position of the blocking member 13, it can effectively block the further reverse movement of the connecting rod 5 of the riding frame. At the same time, since the corner of the L-shaped flap 12 catches the side wall of the bracket 1, the L-shaped flap 12 will not flip downward when subjected to resistance, thus enhancing the stability of anti-reversal.

[0038] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model; without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
