Description

Technical Field

[0001] The utility model relates to the technical field of TBM belt stacking, in particular to an automatic stacking device for a TBM continuous belt conveyor before vulcanization. Background Art

[0002] With the widespread application of TBM in tunnel construction, its efficient, continuous and economical slag discharge characteristics are widely used in various transportation systems. In TBM construction, continuous belts are mainly steel wire core conveyor belts. Its long transportation distance, economical, fast and efficient slag discharge capacity have absolute advantages for TBM excavation to achieve fast and continuous construction. However, the existing belt extension technology mostly adopts the belt heating and pressurization vulcanization process, but due to the belt length limitation, the belt extension vulcanization process must be stopped every half of the same length of excavation, and each vulcanization only consumes at least 12 hours, which has a great impact on TBM excavation construction. At present, most belt manufacturers use 450 to 600 meters as a roll, with a total weight of about 13 to 20 tons. For easy transportation, it is generally wound into two rolls. When the continuous belt needs to be vulcanized, it needs to be stacked neatly in advance and transported to the vulcanization platform for double-head vulcanization. In the past, the belt was stacked manually with lifting equipment such as truck cranes and gantry cranes. This method has the disadvantages of slow stacking speed, large labor input, low efficiency and high risk factor.

[0003] In summary, the present application now proposes a TBM continuous belt conveyor automatic stacking device before vulcanization to solve the above-mentioned problems. Utility Model Content
