A through-hole Ⅳ is arranged on the fire door. A stud Ⅱ is passed through the through-hole Ⅳ and the hanging shaft connecting through-holes of the two connecting plates. A fire door connecting nut is arranged at the protruding end of the stud Ⅱ.

[0010] To further implement the present utility model, the stabilizing mechanism further includes a steel pipe and an insulating pipe sequentially sleeved outside the stud Ⅰ from inside to outside.

[0011] To further implement the present utility model, flat washers and spring washers are sequentially arranged between the traveling wheel nut and the stabilizing nut and the traveling wheel seat from inside to outside. A flat washer is arranged between the spring washer and the nut to prevent the spring from accidentally falling off from one side of the nut.

[0012] To further implement the present utility model, pads are symmetrically arranged at both ends of the horizontal shaft rod of the hanging shaft, and the pads are attached to the inner side walls of the traveling wheel seats.

[0013] To further implement the present utility model, the bearing includes a deep groove ball bearing and a bearing gland, and the deep groove ball bearing and the bearing gland are fixedly connected by screws.

[0014] To further implement the present utility model, a spacer sleeve is sleeved between the traveling wheel and the traveling wheel shaft.

[0015] To further implement the present utility model, grooves are symmetrically arranged on the top surface of the fire door. The through-hole Ⅳ is arranged below the grooves, and the center of the through-hole Ⅳ is arranged on the central axis of the grooves.

[0018] The beneficial effects of the present utility model compared with the prior art are:

[0019] The utility model uses two walking wheels on both sides of a single guide rail, thus ensuring the reliability of the walking wheels on the single guide rail and solving the problem of derailment of the fire door of the double-guide rail trolley in the high-purity silicon submerged arc furnace; the double-headed stud I of the stabilizing mechanism and the horizontal shaft rod of the hanging shaft are used to connect two walking wheel seats, and the double-headed stud I and the horizontal shaft rod of the hanging shaft work together to stably clamp the walking wheels on the single guide rail. The vertical shaft rod of the hanging shaft is used to connect the fire door connection mechanism, and the arrangement of the stabilizing mechanism and the hanging shaft also facilitates flexible disassembly and replacement.

[0020] In the prior art, when the track is deformed by heat or the gauge of the double tracks changes, the fire door trolley derails or jams. However, in the utility model, a single guide rail is arranged between two walking wheels, and there is no change in the spacing of the single guide rail, thus preventing jamming or derailment during walking.

[0021] The utility model clamps an H-shaped steel rail between two walking wheels, and keeps the stability of the walking wheel seat through the double-headed stud I and the steel pipe and insulating pipe sleeved outside it, solving the problems that the fire door jams or derails due to the heat deformation of the double guide rails, affecting the tapping of the submerged arc furnace; and solving the problem that the fire door of the double-guide rail trolley is large in size and difficult to disassemble and repair.
