The inspection of general underground main earthed electrode plate, employing be directly propose to check or adopt fixed pulley and with the mode of the cylinder lay winding wire ropes of crank to realize the lifting of main earthing pole, select jack position pin to insert at lifting destination county fixing.In actual applications, find that it has following shortcoming: 1. ground connection pole plate is heavy, when using crank to drive the direct lay winding wire ropes of cylinder to be elevated, compare effort.2. easily there is safety misadventure.When staff uses crank lay winding wire ropes centre to occur being short of physical strength, there will be " magnifying slip " phenomenon, crank is easy to the staff that injures.3. easily there is maloperation, destroy protective grounding system.Non-working person likely privately operating rocker handle promote main earthing pole but do not return to normal operating condition, make main earthing pole there is no normal place in operation.4. cylinder side only has a pin jack, accurately cannot control the hoisting depth of main earthing pole.The shortcomings such as the lifting due to this device is not in place; limit the comprehensive and careful property that main earthing pole checks; cause inspector can not the main earthing pole Problems existing of Timeliness coverage; thus the grounding resistance of underground pro tective earthing system is increased, bury safely hidden danger to personal safety and electrical equipment.
At present, the lifting detecting device of domestic coal master's earthing pole, or adopt aforesaid way.Reliable, perfect technical scheme is not taked to solve above device Problems existing.
Summary of the invention
The object of the invention is the deficiency for existing in current prior art, manufacturing a kind of reliable and secure main ground connection pole plate lifting inspection device.This equipment safety, reliable, easy to operate, the maloperation of field staff can be prevented again, reach and make the safer object easily of the inspection of earthing pole.
For achieving the above object, the technical solution used in the present invention is:
In a kind of coal mine underground sump, main ground connection pole plate checks jacking system, comprise the main ground connection pole plate in shaft sump, it is characterized in that, also comprise pulley jacking system, unidirectional Worm and worm-wheel gearing, crank and permanent seat, described pulley lifting system comprises the pulley base and fixed pulley, steel rope and cable drum that are fixed on shaft sump, described fixed pulley is fixed on pulley base, and cable drum rotating manner is arranged on permanent seat by bearing seat;
Unidirectional Worm and worm-wheel gearing comprises the intermeshing turbine of unidirectional rotation and worm screw, the bearing seat supporting worm screw is established at worm screw two ends, bearing seat is fixed on permanent seat, described crank is removably rotationally connected with the sleeve that worm screw is extended, and turbine drives mode is connected to cable drum and fixes with pin;
Described steel rope lower end connects main ground connection pole plate, and the other end passes fixed pulley, finally around on cable drum.
In described coal mine underground sump, main ground connection pole plate checks jacking system, and it is characterized in that, the worm and gear of described unidirectional Worm and worm-wheel gearing has unidirectional self-lock function.
The invention has the beneficial effects as follows:
Installing and using of main ground connection pole plate lifting inspection device, larger transmitting ratio is realized on the one hand by worm and gear, easily can complete the lifting of main earthing pole, dramatically reduce the labour intensity of inspector and facilitate the examination and maintenance of inspector to main earthing pole; The reverse self-locking function of this device, can make ground connection pole plate locate on the other hand, adds safety when checking ground system and convenience.Guarantee the serviceable condition of main earthing pole, ensure the safety of the perfect of whole colliery ground system and underground power supply system.

Detailed description of the invention
Do into a description below in conjunction with accompanying drawing to the specific embodiment of the present invention:
In a kind of coal mine underground sump, main ground connection pole plate checks jacking system, comprise the main ground connection pole plate 11 in down-hole suction well 12, it is characterized in that, also comprise pulley jacking system, unidirectional Worm and worm-wheel gearing, crank 1 and permanent seat 6, described pulley lifting system comprises and is fixed on pulley base 9 above suction well 12 and fixed pulley 10, steel rope 8 and cable drum 5, described fixed pulley 10 is fixed on pulley base 9, and cable drum 5 rotating manner is arranged on permanent seat 6 by bearing seat;
Unidirectional Worm and worm-wheel gearing comprises the intermeshing turbine 5 of unidirectional rotation and worm screw 3, the bearing seat 1 supporting worm screw is established at worm screw 3 two ends, bearing seat is fixed on permanent seat 6, described crank 1 is removably rotationally connected with the sleeve 14 that worm screw 3 is extended, and turbine 4 type of drive is connected to cable drum 5 and fixes with pin 7;
Described steel rope 8 lower end connects main ground connection pole plate 11, and the other end passes fixed pulley 10, finally around on cable drum 5.
In described coal mine underground sump, main ground connection pole plate checks jacking system, it is characterized in that, worm gear 4 and the worm screw 3 of described unidirectional Worm and worm-wheel gearing have unidirectional self-lock function.
Elevator dynamic structure is the operating station of whole device, by people swagger or motor provide rotary power, turbine 4 and worm screw 3 transmission self-locking main portions.Worm screw 3 is located by bearing seat 2, and cable drum and turbine 4 utilize pin 7 fixedly to become a coaxial swivel.Rotated a circle by worm screw 3, drive worm gear 4 to rotate a gear, and then drive the rotation of cable drum.Steel rope 8 one is fixed and is wrapped on cable drum 5, the rotation lay winding wire ropes of cable drum, and steel wire penetrating is fixed on the fixed pulley 10 of top, is promoted by main ground connection pole plate 11.
