Description

Technical Field

[0002] To date, more than 90% of the coal mine water tank excavation in the country still remains in the most traditional and backward manual excavation and mud transportation by mine trucks. This excavation method has the characteristics of high labor intensity, large number of personnel, long excavation period, slow clearance speed, low efficiency, slow speed, incomplete clearance, pollution of tunnel environment, and restricting production development. The maximum clearance speed does not exceed 30m3 / h, which is far from meeting the clearance needs of modern large-scale coal mines with tens of millions of tons. In modern large-scale coal mines, the higher the coal output, the greater the amount of coal powder, the greater the industrial water consumption, the greater the siltation of the water tank, the smaller the water volume of the water tank, and the shorter the service life. It is impossible to clean the water tank in time and effectively, which affects the safe operation and empty tank capacity of the drainage system, resulting in a decrease in the water tank's ability to prevent water inrush, which brings major hidden dangers to the safe production and operation of the mine. Therefore, the excavation of coal mine water tanks is a bottleneck restricting the safe production of mines. In serious cases, it directly endangers the lives of mines. Therefore, water tank cleaning is both a difficulty and a pain point for coal mines. Summary of the invention

[0025] The hydraulic pumping mechanism is equipped with a hydraulic piston booster pump 9. The pump is driven by an electric motor through an elastic coupling to drive an axial series pump (referred to as an oil pump). The oil pump sucks low-pressure oil from the oil tank and then discharges high-pressure oil.

Hydraulic pumping mechanism, rigid crawler high torque hydraulic walking device 11, and equipped with 200m 3 / h emergency rescue hydraulic pump and other parts.

[0027] 1) The turbine worm gear slewing support 1 is mainly responsible for the left and right rotation of the entire collecting hopper 2 to collect the coal sludge on both sides of the water silo tunnel.

[0028] 2) Collecting hopper 2, which is mainly responsible for collecting and storing the coal slurry required by the hydraulic pumping mechanism.

[0029] 3) Two groups of mixing and collecting devices 3 are mainly responsible for transferring the coal slurry brought by the rapid excavation and shoveling equipment to the middle hopper at the rear through the rotation of the left and right hydraulic motors, and then connecting the collecting hopper 2 and the pumping equipment as a whole through an 8-inch steel telescopic flexible connecting pipe. The purpose of using the steel telescopic flexible connecting pipe is to facilitate the left and right swing of the collecting hopper 2 to collect the coal slurry in the roadway, and then transport it to the high-efficiency cyclone centrifugal dehydration place through the lifting and collecting remote transportation equipment through a kilometer-long closed pipeline for subsequent continuous dehydration of the coal slurry.

[0030] 4) Two groups of mixing and gathering screws are independently driven by their own hydraulic motors, and the speed can be adjusted and set through the control system to ensure the amount of coal slime collected and supplied to the pumping mechanism in time.

[0031] 5) Aggregate protection and magnetic iron removal device 5. According to the characteristics of many debris on the underground water tank of the coal mine, two protective devices are specially added in front of the aggregate hopper 2. The first one is mainly to prevent debris and large pieces of coal gangue from entering the aggregate hopper 2 to prevent clogging the conveying pipeline. The second one adds a magnetic iron removal device 5, which is mainly to protect the safe operation of the pumping mechanism and subsequent dehydration equipment.

[0032] 6) The aggregate hopper lifting cylinder 6 is mainly responsible for the lifting, lowering and bottom cleaning of the entire hopper. It can be used for cleaning work on complex ground, especially when clearing and passing through low bends in water tanks. It has good passing performance and cleans the bottom thoroughly.

[0033] 7) Design of lifting aggregate remote conveying equipment, equipped with hydraulic piston booster pump 9, with large feed suction, strong self-priming ability, and self-priming function of more than 5 meters; wear resistance, service life increased by more than 10 times, and significant effect on sand and stone solid particles; high concentration, can convey solid-liquid mixture with a water content of more than 80%; high efficiency, operating efficiency of more than 95%; fast clearance speed, pumping capacity up to 100m 3 / h, the conveying pipeline is fully closed, the conveying distance is 2000 meters horizontally and 200m vertically, the energy-saving pump feed pressure is up to 20 kg and the pressure is adjustable, which is more than 30% higher than the existing slurry pump feed speed, greatly improving the work efficiency; the lifting aggregate remote conveying equipment collects the coal slurry through the aggregate hopper, and there are two large-capacity hydraulic plunger pumps in the self-priming pump cavity, one sucking and one discharging, reciprocating, working back and forth, with a pumping mechanism, the coal slurry is transported to two high-efficiency continuous coal slurry dehydration equipment a kilometer away by pipeline for subsequent coal slurry dehydration treatment.

[0034] 8) Rigid crawler high torque hydraulic travel device 11. It adopts low-speed, large-displacement, high-torque, hydraulic motor-driven crawler travel mode, with strong driving force, good passing performance and strong climbing ability.

[0035] 9) The remote control device can realize all the operating functions of the whole machine including starting and stopping, working switch, gathering and conveying, forward and reverse pumping, walking, hopper raising, lowering and rotating.

[0036] When clearing the silo, first use the lifting aggregate kilometer conveying equipment to open the water inlet for rapid excavation. When the silo mouth has been cleared and excavated down to pass the low bend about 15 meters, and there is a certain amount of equipment storage space that can meet the simultaneous operation of two devices, the lifting aggregate kilometer conveying equipment temporarily withdraws from the silo, and the rapid excavation and shoveling equipment enters the silo first, and then the lifting aggregate kilometer conveying equipment enters the silo. When both equipment reach the appropriate front and rear positions, the rapid excavation and shoveling equipment is remotely or manually operated to stir the coal slime that has settled in the silo for the lifting aggregate conveying equipment, and continuously stir and shovel the coal slime slurry.

[0037] The rapid clearing and shoveling equipment, according to the working needs of the lifting aggregate conveying equipment, stirs and shovels the coal slurry back and forth between the water bin and the lifting aggregate conveying equipment. When moving towards the water bin mouth, the bucket of the rapid clearing and shoveling equipment is lowered, and the coal slurry water is shoveled to the lifting aggregate kilometer pumping equipment while stirring, which is convenient for the collection and pumping of the lifting aggregate conveying equipment. After arriving at the lifting aggregate conveying equipment, the bucket of the rapid clearing and shoveling equipment is lifted up, and quickly retreated to the thick coal slurry in the water bin, and the bucket of the rapid clearing and shoveling equipment is lowered. The mixer in the bucket of the rapid clearing and shoveling equipment can also rotate in forward and reverse directions. This cycle is repeated to continuously provide coal slurry to the lifting aggregate conveying equipment.

[0038] The lifting aggregate conveying equipment works in a fixed position or moves in a small range at the low bay of the water tank. The coal sludge shoveled by the quick excavation and shoveling equipment is mixed and aggregated and transported to the rear hopper. In order to prevent debris in the water tank from entering the aggregate hopper 2, two protective nets are designed. The first one is used to prevent large particles and debris, and the second one is a magnetic strip protection net. It is equipped with two sets of mixing aggregate devices 3, two-stage aggregate protection devices 4, and aggregate hopper lifting cylinders 6, so as to realize multiple functions such as rotation, lifting, stirring, and iron removal, which can maximize the efficiency of aggregate collection of coal sludge, and at the same time prevent the equipment from damaging the mixer hydraulic motor during the excavation process. The rotating three-dimensional support arm at the rear of the aggregate hopper 2 further strengthens the longitude and latitude torsional strength and bearing capacity of the aggregate hopper 2 and the three-dimensional support arm, and relieves and releases the torsional stress caused by the rotation with load.

[0039] One-button start electrical operation platform, motor, electric control box, hydraulic oil tank, high-rise design, one-button start lifting, equipped with emergency rescue hydraulic pump, 200m 3 / h to cope with the adverse factors such as water leakage or "storage run" during dredging, and the safety production operation coefficient is greatly guaranteed.
