Described pin rail one end top is provided with mechanical brake device.
Described mechanical brake device comprises brake block and fixed axis, and brake block one end perforate is installed in through fixed axis on the housing of cut part; The movable overlap joint of one end is on the bearing pin of pin rail, and overlap joint rotates under the promotion of pin rail at the end on the bearing pin, when not reaching bearing pin; Brake block just automatically resets, like this perseveration, and outage back coal-winning machine is out of service and when oppositely sliding; The brake block backward rotation will be stuck by bearing pin, and coal-winning machine then stops to slide; In the time need not braking in the coal-winning machine running, can brake block be started, get final product with positioning bolt is fixing.
Described pin rail is supported on chute top one side through the pin rail chair.
Described traction element is equipped with electro-magnetic braking device.
Described electro-magnetic braking device comprises electromagnetism electricity loss brake and explosion-proof casing, and the electromagnetism electricity loss brake is installed in the motor output shaft place, and the outside is with explosion-proof casing.When unexpected power failure, the electromagnetism electricity loss brake can make motor output shaft braked, and coal-winning machine stops to slide.
Described gear is installed on the power transmission shaft of traction element, and front and back are provided with 2 altogether.
Described piston shoes are fixed on the shell of traction element, and the groove of piston shoes is fastened on the pin rail outside, and piston shoes slide along the pin rail, guarantee the location of coal-winning machine.
Compared with prior art, the beneficial effect that had of the no chain alternating current traction coal-winning machine of the utility model is:
1, design gear pin rail transmission, the chainless haulage of realization low seam mining machinery, transmission is more steady; Speed is more even: a side mount pin rail and a gear above the coal-winning machine chute, and volume is littler, can be used for low seam mining machinery; Substitute the anchor chain chain gear transmission in the former coal-winning machine; Realize the chainless haulage of low seam mining machinery, make the low seam mining machinery transmission more steady, speed is more even;
2, design and installation mechanical brake device, electro-magnetic braking device; Make course of work safety and reliability: above pin rail one end, be provided with mechanical brake device; Electric control box partly is equipped with electro-magnetic braking device; Make the very first time realization equipment braking of coal-winning machine, prevent security incident, make equipment more safe and reliable in outage.
