Description
Technical Field
[0001] The invention relates to the technical field of light rail track clamping, in particular to a track clamping device for a mine light rail. Background Art
[0002] The tracks of underground mine transport lanes need daily maintenance to prevent and reduce the derailment of transport vehicles. However, during long-term transportation, the tracks fixed with sleepers and spikes cannot ensure that the rail dimensions are always within the standard range. In the past, welding was mainly used to ensure the rail dimensions. In production activities, underground welding operations belong to the first-level hot work category, and the operation method is cumbersome and inefficient.
[0003] Underground tracks are usually fixed with sleepers and spikes, but during long-term high-frequency transportation, due to factors such as vibration and load pressure, the rail dimensions often deviate and are difficult to always maintain within the standard range. This deviation may cause unstable vehicle operation or even derailment accidents.
[0004] In order to ensure the stability of the rail dimensions, welding is currently used for maintenance. This method strengthens the connection between the rail and the fixed structure through welding, temporarily solving the problem of loose rails, but it needs to be strictly implemented in accordance with the hot work process. Hot work approval is complicated, construction preparation time is long, maintenance efficiency is reduced, and welding is prone to fire and explosion hazards. In addition, the transportation and installation of welding equipment are also limited by underground space.
