Abstract
The utility model relates to a special sand-block brake shoe for railway vehicles used for repairing the scratching surfaces of train wheels, which belongs to the technical field of the manufacture of railway vehicle wheel repairing tools. The utility model is mainly composed of a shoe back and a sand block, wherein the sand block and the shoe back are connected into a whole by adhesive. The utility model has the advantages that when a carriage with the scratched vehicle wheels can not be repaired by bogies and changing wheel pair, the utility model is arranged in the position of the original vehicle wheel brake shoe, the scratched surfaces of vehicle wheels can be repaired through braking and grinding in a section, the time and the labor can be saved, and the utility model is convenient for meeting an emergency.
Description
The utility model relates to a kind of sand lump brake shoe that is specifically designed to repairing train wheel scratch tread.Belong to rolling stock fix tool manufacturing technology field.
Rolling stock because of a variety of causes, needs the emergency braking brake in the operation way; But often, cause brake shoe and wheel lockup, thereby make wheel tread flat because braking force is big or trainload is bigger.When scar degree of depth overgage, the stationarity of train operation is just poor, promptly produces bigger vibration or impact, even causes wheel to cut an accident etc.This situation not only can influence other parts of vehicle and railway track operation life, can make also that cargo-carring various goods collision impacts are damaged on the vehicle.In the prior art, result of the above problems is that the compartment is thrown to special salvage shop, and change of wheels is repaired.And uncouple, the reparation way link of change of wheels is many, the cycle is long, work capacity is big, costs dearly, and is very difficult, often influences the normal use of vehicle, brings great inconvenience and difficulty for railway operation department.
Goal of the invention of the present utility model is to provide a kind of Emergency Tool of field repair railroad train wheel flat---rolling stock sand lump brake shoe, need not uncouple, and change wheel.
Goal of the invention of the present utility model can be achieved by following technical measures: promptly by a watt back of the body 1, the rolling stock sand lump brake shoe formed of sand lump 2, sand lump 2 is to be one by adhesives 3 with watt carrying on the back 1 leak-tight joint.Sand lump 2 adopts industrial emery wheel, and is circular arc.
The utility model has the advantages that conspicuous.When not uncoupling in the wheel compartment that is scratched, when changing the wheel reparation, as long as the sand lump brake shoe is contained in the wheel flat position, through certain interval drag friction grinding (also can use hand braking fastening friction), destroy the vertex of scratch tread, reach the flat sliding effect of repairing.Time saving and energy saving, convenient emergent, very suitable.
Accompanying drawing and drawing explanation:
Fig. 1 is a main TV structure scheme drawing of the present utility model;
Fig. 2 is a left TV structure scheme drawing of the present utility model;
Wherein: 1-watt of back of the body 2-sand lump 3-adhesives
This specification sheets the 5th part and in conjunction with the accompanying drawings 1-2 full implementation example of the utility model has clearly been described, no longer repeat here.It is a kind of effective emergent reclamation activities that sand lump brake shoe grinding wheel flat tread is used in evidence.The wheel tread that the general scratch degree of depth exceeds standard is loaded onto the utility model, the brake twice of stopping, and through interval braking grinding, can be with within the vehicle tread projection grinding to gauge scope.When the utility model uses, lay down the original brake shoe of wheel of vehicle earlier, it is installed on the car brakeing beam brake head, be regardless of closely connected with brake head anyway; Get final product by brake shoe nostril brake shoe thousand of string downwards from brake head top.
Claims (2)
1, a kind of rolling stock sand lump brake shoe in order to the repairing train wheel tread is characterized in that: be made up of a watt back of the body (1), sand lump (2), sand lump (2) is closely as one by an adhesives (3) and a watt back of the body (1).
2, rolling stock sand lump brake shoe according to claim 1, it is characterized in that: sand lump (2) adopts industrial emery wheel, and is circular arc.
