AI Technical Summary
The existing inclined shaft transport trolley cannot lock onto the track in time in case of malfunction, posing a risk of falling and overturning.
A fall protection device was designed, including an anti-overturning bracket, a spacer rod, a wedge plate, a fall protection bracket, a pulley assembly, and a tension spring. The mechanical structure automatically triggers the wedge plate to lock the track when the wire rope breaks, and the anti-overturning bracket provides lateral stability to ensure the safety of the trolley.
It achieves automatic rail locking the moment the wire rope breaks, preventing the trolley from falling and preventing overturning during braking, providing dual safety protection without manual operation and reducing emergency response pressure.

Abstract
Claims
1. A fall protection device for an inclined shaft transport car, the transport car being connected to a double drum winch by a wire rope, characterized in that The transport trolley is held tightly to the track by an anti-fall device, which includes an anti-overturning bracket, a spacer rod, a wedge plate, an anti-falling bracket, a pulley assembly, a first tension spring, and a second tension spring. The anti-overturning bracket is disposed at both ends of the spacer rod and is connected to the anti-falling bracket. Both the anti-overturning bracket and the anti-falling bracket are fixedly connected to the transport trolley. The pulley assembly is mounted on the anti-fall bracket. The first tension spring is mounted on the wire rope of the double-drum winch. The wire rope is mounted on the pulley assembly and connected to the wedge plate. The two ends of the second tension spring are respectively connected to the wedge plate and the anti-overturning bracket. When the wire rope breaks, the first tension spring resets, the second tension spring resets and pulls the wedge plate to lock the track.
2. The anti-falling device for the inclined shaft transport trolley according to claim 1, characterized in that, The fall arrestor is connected to the transport trolley via a first positioning member. One end of the first positioning member is welded to the transport trolley, and the other end is detachably connected to the fall arrestor via a first fastener.
3. The anti-falling device for the inclined shaft transport trolley according to claim 2, characterized in that, The first positioning element is welded to the transport trolley.
4. The anti-falling device for the inclined shaft transport trolley according to claim 1, characterized in that, The anti-overturning bracket is connected to the transport trolley via a second positioning member. One end of the second positioning member is welded to the transport trolley, and the other end is detachably connected to the anti-overturning bracket via a second fastener.
5. The anti-falling device for the inclined shaft transport trolley according to claim 4, characterized in that, The second positioning element is welded to the transport trolley.
6. The anti-falling device for the inclined shaft transport trolley according to claim 1, characterized in that, The anti-overturning bracket is detachably connected to the fall arrestor bracket via a third fastener.
7. The anti-falling device for the inclined shaft transport trolley according to claim 1, characterized in that, The anti-overturning bracket is connected to the spacer rod by a fourth fastener.
8. The anti-falling device for the inclined shaft transport trolley according to claim 1, characterized in that, The pulley assembly is configured in two sets, which are respectively located in the top and side areas of the fall arrestor; the pulley assembly is connected to the fall arrestor via a fifth fastener.
9. A trolley for transporting goods in an inclined shaft, characterized in that, The transport vehicle is equipped with a fall prevention device as described in any one of claims 1 to 8.
10. An inclined shaft transportation system, characterized in that, The device includes a track, a double-drum winch, a transport trolley, and a fall arrestor as described in any one of claims 1 to 8, wherein the fall arrestor is mounted on the transport trolley, which is used to move on the track; and the fall arrestor is connected to the wire rope of the double-drum winch.
