The invention relates to the field of power construction technology, and particularly to a floor type handcart switchgear integrated track. The floor type handcart switchgear integrated track comprises a left-handed screw, a right-handed screw and a screw combined operating rod. The left-handed screw and the right-handed screw are fixedly connected with two ends of the screw combined operating rod. The left-handed screw and the right-handed screw are in threaded connection with an integrated track. The integrated track comprises a fixed track base, a fixed track, a spacing bent trough and an auxiliary track. The auxiliary track comprises a base plate, a spacing bent plate, and a pair of side tracks which are parallelly arranged on the base plate. A guiding trough is formed between the twoside tracks. The side track at the side which is far from the spacing bent plate is provided with a bell mouth guiding trough which is outwards opened. The base plate at the bell mouth guiding troughis an oblique surface which inclines downwards. The floor type handcart switchgear integrated track realizes a fact that a switchgear handcart can be more safely, stably, conveniently and accurately pushed into the switchgear. Furthermore the floor type handcart switchgear integrated track has advantages of simple structure, convenient operation and effective efficiency improvement and safety improvement of personnel.
