This utility model discloses an inclined shaft operation trolley, including a trolley body. The trolley body has multiple platforms spaced apart along its direction of travel. When the trolley body is located in the inclined shaft, the platforms are horizontally arranged. At least one platform has a telescopic top support on its upper surface and a telescopic bottom support on its lower surface. The telescopic top support can extend relative to the top wall of the trolley body facing the inclined shaft to partially embed itself in the top of the inclined shaft, and the telescopic bottom support can extend relative to the bottom wall of the trolley body facing the inclined shaft to partially embed itself in the bottom of the inclined shaft. All telescopic top and bottom supports are distributed on at least two platforms. This utility model ensures stable support for the mechanically integrated mobile platform trolley during static operation, ensuring that the mobile platform trolley can establish a sufficiently rigid connection structure and static friction with the tunnel face during operation, reducing the load on the wire rope, absorbing vibrations and impacts generated during operation, and bearing part of the weight.

Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically to an inclined shaft operation trolley. Background Technology

[0002] Currently, during the construction of steep inclined shaft tunnels, due to the large tunnel gradient, personnel cannot work directly within the inclined shaft. Mobile platform vehicles are mostly used for transportation, operations, and auxiliary tools. These mobile platform vehicles are steel structures with wheels underneath for support, and are powered by winches outside the shaft and pulled by steel cables. The mobile platform vehicles currently used in inclined shaft tunnels mostly weigh between several tons and tens of tons. The platforms are lightweight and have a small load capacity; in a static state, they can usually maintain stability within the tunnel solely through the tension provided by the steel cables.

[0003] However, with the increasing mechanization of construction technology, mechanized mobile platform vehicles have begun to appear on steep inclined shaft construction sites. These mechanized mobile platform vehicles are heavier than traditional ones, and the loads and impacts from their various working mechanisms during operation are significant. If, during static operation, only the holding tension of the winch wire rope is considered to ensure the stability of the entire equipment, the overall safety of the vehicle will be reduced. The vehicle requires more robust safety measures. Utility Model Content

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] This utility model relates to an inclined shaft operation trolley. By arranging multiple platforms at intervals along the trolley's direction of travel, it not only accommodates the equipment required for drilling and maintenance but also serves as a mounting carrier for support legs. By installing telescopic top supports and telescopic bottom supports on at least one platform, and distributing these supports across at least two platforms, the integrated mechanical mobile platform trolley achieves stable support during static operations. This ensures a sufficiently rigid connection and reduce static friction between the mobile platform trolley and the tunnel face during operation, minimizing the load on the wire ropes, absorbing vibrations and impacts generated during operation, and bearing a portion of the weight. The top-embedded telescopic top supports, the bottom-embedded telescopic bottom supports, and the winch system provide triple protection for the entire operating platform, ensuring that the mobile platform trolley will not lose control and fall even if any safety device fails during operation.
