Abstract
The utility model relates to a stopper is prevented running by improved generation, including the stopper body, install control mechanism and actuating mechanism on the stopper body, actuating mechanism passes through link mechanism and connects the braking skate, just the braking skate wholly is trapezoidal form, the lower surface of braking skate is followed its length direction and is provided with a plurality of antiskid tooth, and the distance between the adjacent anti -skidding tooth is equal, all is provided with the non slipping spur in the both sides of braking skate, and non slipping spur adoption elastic material makes. The utility model has the advantages of simple structure and reasonable design, through being provided with anti -skidding tooth and non slipping spur, can prevent to brake the skate phenomenon of skidding appears on the one hand, influences it and uses, and on the other hand can prevent to brake the rigid friction between skate and the rail effectively.
Description
Technical field
The utility model relates to a kind of safety guard of locomotive crane tool, particularly relates to a kind of improved type Travelling-preventing brake.
Background technology
The elevator machinery orbited, span winch, crane, bridge crane etc. that harbour uses, except the safety system of self, must be equipped with prevention natural wind, to the emergent safety guard plate that rail mounted elevator machinery may work the mischief.In recent years, locomotive crane tool, due to not anti-race device safely and effectively, and causes the serious accident of fatal crass to happen occasionally.The harm that the wind-force of the Nature causes rail mounted elevator machinery, two kinds of phenomenons can be divided into: a kind of is having the high wind occurred in weather forecast situation, although its wind intensity is very large, but operating personal can according to weather forecast, predetermine stopping production, before high wind arrives, take multiple countrmeasure, such as: reinforcing grappling, add Windproof inhaul cable etc., is all highly effective method.Another kind does not obtain weather forecast, crane is in normal loading and unloading operation process, suddenly powerful fitful wind is run into, crane operator concentrates one's energy to note loading and unloading operation, is not easy to discover, after crane is by wind blows, due to anti-race brake equipment not emergent on crane, often make operating personal be caught unprepared, the crane that operating personnel cannot stop by wind to blow away in time, and cause serious consequence.In order to make crane operator in operator's compartment, can take emergency measures at any time, prevent crane from running in time, avoid having an accident, therefore occurred Travelling-preventing brake, Travelling-preventing brake can guarantee safety effectively, for trouble and worry is eliminated in the use of locomotive crane tool.
According to the Travelling-preventing brake that Chinese Patent Application No. is 02258338.6 announcement, the brake shoe of this Travelling-preventing brake is not provided with anti-skid device, easily occur skidding between brake shoe and rail in use procedure, be rigid friction between brake shoe lower surface and rail on the other hand, all damage is caused to brake shoe and rail.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of improved type Travelling-preventing brake.
The utility model is achieved through the following technical solutions:
A kind of improved type Travelling-preventing brake, comprise drg body, drg body is provided with control mechanism and driver train, described driver train connects brake shoe by connecting rod mechanism, and described brake shoe entirety is in echelon form, the lower surface of described brake shoe is provided with several anti-slop serrations along its length, and distance between adjacent anti-slop serrations is equal, be provided with nonslipping spur in the both sides of brake shoe, and nonslipping spur adopts elastomeric material to make.
As optimal technical scheme of the present utility model, the cross section of described anti-slop serrations is isosceles trapezoid, and the lower end length of anti-slop serrations is greater than upper end length.
As optimal technical scheme of the present utility model, described connecting rod mechanism is flexibly connected by bearing pin with between brake shoe.
As optimal technical scheme of the present utility model, described nonslipping spur is that polyurethane material is made.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, by being provided with anti-slop serrations and nonslipping spur, can prevent brake shoe from occurring skidding on the one hand, affect it to use, effectively can prevent the rigid friction between brake shoe and rail on the other hand.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-drg body; 2-control mechanism; 3-driver train; 4-connecting rod mechanism; 5-brake shoe; 6-bearing pin; 7-anti-slop serrations; 8-nonslipping spur.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of improved type Travelling-preventing brake, comprise drg body 1, drg body 1 is provided with control mechanism 2 and driver train 3, described driver train 3 connects brake shoe 5 by connecting rod mechanism 4, described connecting rod mechanism 4 is flexibly connected by bearing pin 6 with between brake shoe 5, and described brake shoe 5 entirety is in echelon form, the lower surface of described brake shoe 5 is provided with several anti-slop serrations 7 along its length, and distance between adjacent anti-slop serrations 7 is equal, the cross section of described anti-slop serrations 7 is isosceles trapezoid, and the lower end length of anti-slop serrations 7 is greater than upper end length.
Be provided with nonslipping spur 8 in the both sides of brake shoe 5, and nonslipping spur 8 adopts elastomeric material to make, preferably, described nonslipping spur 8 is made for polyurethane material.By being provided with anti-slop serrations and nonslipping spur, can prevent brake shoe from occurring skidding on the one hand, affecting it and using, effectively can prevent the rigid friction between brake shoe and rail on the other hand.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
