Claims (5)

35 claims 1. A trolley comprising a body mounted on a frame with an opening bottom, consisting of two wings, each of which is mounted on a cantilever 40 axes with the possibility of rotation in the vertical plane, and devices for opening and closing the shutters, each of which is formed by a lever pivotally attached to the frame with a roller at the end for interaction with a stop mounted on the path, characterized in that, in order to increase operational reliability , each of the indicated axes is rigidly connected to the sash and mounted with the possibility of lateral movement; at the ends of the axes, cams are rigidly fixed for interaction with straight and curved sections of the guides which are rigidly fixed on the longitudinal 55 beam of the frame, and on the transverse beams in the middle part are rigidly fixed supports for interacting with the free ends of the wings in the closed position. 2. The trolley according to claim 1, on the basis of which, in order to increase the reliability of The invention relates to a mine rail transport and relates to trolleys with bottom discharge. A trolley is known comprising a body mounted on a frame with an opening 5 m bottom, consisting of two leaves, each of which is cantilevered mounted on an axis with the possibility of rotation in the vertical plane, and devices for opening and closing the wings, including 10 hinged lever attached to the body with a roller at the end for interaction with a stop mounted on the track A disadvantage of the known device is the complexity of the design. The purpose of the invention is to increase reliability in operation. This goal is achieved by the fact that each of the axes is rigidly connected to the leaf 20 and mounted with the possibility of lateral movement, cams for interaction are rigidly fixed at the ends of the axes. actions with straight and curved sections of the guides, which 25 are rigidly fixed on the longitudinal beams of the frame, and on the transverse beams c. the middle part is rigidly fixed support for interaction with the free ends of the valves in the closed position. thirty To fix the flaps, a straight section of the guide is made with a slope to the longitudinal axis of the trolley. Figure 1 shows the trolley; in Fig.2 - node 1 in Fig.1: in Fig.Z - view A in 35 of Fig.1; figure 4 is a section bB in figure 1. The trolley comprises a body 1 mounted on a frame, to the longitudinal beams 2 of which brackets are attached 3. Sashes 4 with rigidly connected axles 40 are cantilever mounted in brackets 3 with the possibility of rotation in a vertical plane. Supports 6 are rigidly attached to the transverse beams 5 of the frame in the middle part, and cams 7 are rigidly fixed 45 at the ends of the axes of the wings 4, interacting with guides 8, rigidly fixed to the brackets 3 of the longitudinal beams 2 of the frame. The devices for opening and closing the shutters include a lever 9 pivotally attached to the longitudinal beams 2 of the frame 9 with a roller 10 at the end pivotally connected by a rod 11 to the shutters 4. The cam 7 interacts with curved 12 and rectilinear 13 sections of guides 8 that provides lateral movement of the wings 4; The rectilinear section 13 of the guide is made with a slope to the longitudinal axis of the trolley. Stripes are attached to the free edges of the leaves 4 5 1735098 6 to fix the flaps in the closed position, made with a slope to the longitudinal axis of the line, a straight section of the guide-trolley.
