The telescopic wheel set can adapt to the stairs with different heights, if the stairs are high, an extending length of the ladder climbing wheel is increased, and when the ladder climbing wheel with the lowest vertical height is located on the first step, the ladder climbing wheel with the higher vertical height can make contact with the higher step; and if the height of the stairs is lower, the ladder climbing wheel retracts, and at the moment, a path of each turn ofthe ladder climbing wheel is shortened so that the ladder climbing wheel can adapt to a low-step environment.

Electric hydraulic controlled caving coal method and it hydraulic supporter
ActiveCN100593628CAdd controlAdapt to process requirementsMine roof supportsProps/chocksControl systemElectro hydraulic
The invention relates to coal mine synthesizing exploiting caving top coal technique. Electro-hydraulic control caving top coal method is adopted hydraulic support to finish support caving top coal each procedure. The hydraulic support is made up of low order caving top coal hydraulic support and electro-hydraulic control system. In the electro-hydraulic control system, top beam incline sensor isadded. The flash board jack is adopted travel sensor. The length of the flash board is increased, and the size of the coal discharging is adjusted in order to keep top beam horizontal and increase supporting stability. The coal discharging method includes the following steps: top coal sufficient crashing: adopting single sequence sublevel discharging; top coal middling crashing: adopting the same;top coal difficult crashing: adopting double sequence sublevel discharging. The invention can increase coal discharging control type, improve caving top coal technique adaptability, and realize highyield and high efficiency.

Thin coal seam N00 construction method mining, cutting and anchoring system
PendingCN114810058AIncrease cutting lengthGuaranteed stabilityUnderground miningSurface miningMining engineeringMachine
The thin coal seam N00 construction method mining, cutting and anchoring system comprises a walking mechanism and a cutting mechanism, a shovel plate mechanism, a supporting mechanism, an anchor rod mechanism and a joint cutting mechanism which are arranged on the walking mechanism, and is characterized in that the walking mechanism is composed of a lower base and two walking tracks fixed to the two sides of the lower base; an upper base capable of moving front and back in the length direction of the walking crawler belt is arranged on the lower base, guide columns, first telescopic oil cylinders and positioning blocks are arranged on the two sides of the upper base, the positioning blocks are fixed to the lower base, the guide columns can be inserted into the positioning blocks in a front-back moving mode, and the cutting mechanism and the shovel plate mechanism are fixed to the front end of the upper base. According to the thin coal seam N00 construction method mining, cutting and anchoring system, the upper base is driven by the first telescopic oil cylinder to move forwards on the lower base, the cutting length of the cutting mechanism to a coal seam roadway can be extended under the condition that the whole machine is not moved, and the phenomenon that dead corners which cannot be cut exist on the two sides of the roadway when a cutting head can only rotate is avoided.
