Abstract
The utility model relates to a flat car brake device, which belongs to the technical field of special equipment for highway and railway tunnel buildings. The flat car brake device is characterized in that a brake sheet and a regulation screw are arranged on a brake shoe, and a cam is arranged on a motive power shaft and is in rolling contact matching with the brake shoe. The flat car brake device has the advantages that the material selection is easy, the manufacture is simple, and serious dangerous sources such as electric locomotive rolling and the like are fundamentally eliminated through the arrangement of the flat car brake device, so an electric locomotive is in a controlled state, the construction safety is ensured, and the cost is also saved.
Description
Technical field
The utility model belongs to highway, railway tunnel building specialized equipment technical field.
Background technology
At present, in the tunnel of highway, railway construction process, flat truck is little at the plane curve radius, the gradient is big, in the constructing tunnel of continuous length of grade down, about 18 tons of the horizontal trasportation equipment flat truck bowheaviness in the site operation equipment, flat truck weighs more than 60 ton for contained cubic metre of earth, depend merely on the head brake operation of uncontrollable flat truck at all, in case occur out of control, slip situation such as car, will cause great harm to workman in the hole and equipment, have the possibility of car crash.
Summary of the invention
The purpose of this utility model is: a kind of flat truck brake gear is provided, and it can carry out effective failure-free braking to flat truck.
The technical solution of the utility model is: be fixed with brake facing and plus-minus screw on brake shoe, cam is installed on dynamical axis, cam cooperates with the brake shoe rolling touch.
The beneficial effects of the utility model are: be easy to selection, make simple, by the flat truck braking device is installed, slip major hazard sources such as car from eliminated electric locomotive at all, make it be in controllable state.Both ensure construction safety, saved cost again.
Description of drawings
Fig. 1 is the utility model constructional drawing;
Fig. 2 is the utility model brake shoe constructional drawing.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, the 1st, brake facing, the 2nd, plus-minus screw, the 3rd, brake shoe, the 4th, bearing, the 5th, dynamical axis, the 6th, cam, the 7th, fixing brake shoe device.
Because it is heavier that flat truck delivers native case, the flat truck braking device is installed on the native case flat truck, and 8 tons of brake system of 4 covers are installed altogether, and power adopts electric locomotive to carry the Air compressor air feed, and wheel cylinder promotes the brake facing braking through dowel bar.Plus-minus screw 2 is used for adjusting brake facing 1 and wheel gap.
Claims (1)
1. flat truck brake gear, it is characterized in that: be fixed with brake facing and plus-minus screw on brake shoe, cam is installed on dynamical axis, cam cooperates with the brake shoe rolling touch.
