[0003] In order to save energy and efficiently realize the safe operation of the above-mentioned processes, the hydraulic system is applied in the lifting of mine cages. Currently, the single-direction and single-circulation hydraulic system is used to meet the operation of the shaft with a small production volume. When the shaft is large When many or multiple hydraulic systems need to be installed at the same time, the existing devices cannot meet the production needs well

The invention discloses a mine wellhead full hydraulic altitude difference compensation device which comprises an oil pump used for providing power for the mine wellhead full hydraulic altitude difference compensation device and an electromagnetic relief valve connected with the oil pump in parallel, wherein two electromagnetic directional valves are connected in parallel and then are connected with the oil pump in series, and each electromagnetic directional valve is connected with a control oil circuit. Each control oil circuit comprises a hydraulic motor and a safety valve which are connected in parallel, one ends of the hydraulic motor and the safety valve are connected with a speed regulating valve, and the other ends of the hydraulic motor and the safety valve are connected with the electromagnetic directional valves. A pipe is arranged between the electromagnetic directional valves and the oil pump to be directly connected with an oil tank, the oil tank is further connected with the oil pump and the electromagnetic relief valve, an oil filter is arranged between the oil pump and the oil tank, and the compensation device is provided with a heater connected with the oil tank. The mine wellhead full hydraulic altitude difference compensation device controls more than two hydraulic systems to provide power for more than two lifting saddles through one power source, can achieve simultaneous ascending, simultaneous descending or independent ascending and descending of a plurality of saddles, is simple in structure, stable in operation and convenient to maintain, improves production efficiency and reduces cost.
Description
Technical field [0001] The invention relates to a mine pallet lifting auxiliary equipment, in particular to a full hydraulic height difference compensation device for a mine well head. Background technique [0002] The lifting cages in the mines transport ore or waste rock to the wellhead through the minecart. On the one hand, the height difference between the wellhead and the unloading bin is used to make the heavy truck flow to the unloading bin. On the other hand, the empty minecart after unloading must be lifted. To a certain height, the mine cart will flow back to the empty cart side of the wellhead to complete the work cycle. [0003] In order to save energy and efficiently realize the safe operation of the above procedures, the hydraulic system is used in the lifting of the mine cage. The single-direction, single-cycle hydraulic system currently in use can meet the operation of the shaft with a small production volume. When more or more hydraulic systems need to be installe...
