Abstract
The utility model discloses an inner belt type brake, which comprises a cross-shape joint, tensioning bolts, a lever, a shaft, a slide bar, a screw, a spring, rollers, a steel belt and a brake wheel, wherein one end of the steel belt is fixed on the slide bar through a pin; the pin and the slide bar are connected through the screw; the other end of the steel belt expands outward through the two tensioning bolts; the other end of each tensioning bolt is fixed with the lever through the shaft; the other end of the slide bar and the other end of the lever are respectively fixed at the same end of the cross shape joint through the shaft; one end of the spring is fixed on the lever; the other end of the spring is fixed at one end of the cross-shape joint through the shaft; and the rollers are installed on the heads of three joints of the cross-shape joint. The inner belt type brake provided by the utility model has the advantages of great braking torque, safety, reliability and compact structure, thereby being suitable for braking of multiple mechanical equipment and multiple vehicles.
Description
Technical field
The utility model relates to a kind of break, relates in particular to a kind of interior band brake.
Background technique
When the installation, maintenance rotating machinery, need a kind of break that transmission part is stopped operating in position accurately usually, with the convenient operation of installing or repairing, for example, aluminium oxide is produced installation and maintenance operation with inner liner of rotary kiln, be like this.In the past, when the installation of inner liner of rotary kiln and maintenance operation, do not have special braking device, used manual work adjustment merely, and when needs carry out operation in certain position, often just can stop in place several times repeatedly, time-consuming taking a lot of work, efficient is very low.
Band formula break beyond the band brake commonly used; In use there are a series of shortcomings in this break; It is little to lose braking moment, and outer-enwraped type band brake circumference wrap angle generally accomplishes which greater than 207 °, and braking moment is the exponential function of wrap angle; Because wrap angle can't be accomplished fully big, thereby the size of big limitations braking moment; It two is the steel band pulling force of originally experiencing, and is easily broken, promptly influences working life, influences safety again; It three is that structure and shape is bigger, and it is many to take up space.Because various shortcoming has limited this break using scope.
Summary of the invention
A kind of braking moment is big, safe and reliable with regard to being to provide in order to address the above problem for the purpose of the utility model, compact structure and the high interior band brake of efficient.
The utility model is realized above-mentioned purpose through following technological scheme:
The utility model comprises cross shaped joint, tensioning bolt, lever, axle, slide bar, screw, spring, roller, steel band and Brake drum; One end of said steel band is fixed on the said slide bar with pin; Said pin is connected with said screw with said slide bar; The other end of said steel band is through 2 outside distendings of said tensioning bolt, and the other end of said tensioning bolt is fixed with said lever through said axle, and the other end of said slide bar and the other end of said lever are separately fixed at the same end of said cross shaped joint through said axle; Said spring one end is fixed on the said lever; The other end of said spring is through a said end that is fixed on said cross shaped joint, and three joint heads of said cross shaped joint all are equipped with said roller, and said roller supports said steel band respectively.
Further, said spring is that elastic force is the spring of 600N.
Further, the internal surface of said Brake drum is the elastic metal strip that studs with friction material.
The beneficial effect of the utility model is:
The utility model is adjacent to the inner periphery of Brake drum through the outside distending of tensioning bolt, utilizes the frictional force between the inner periphery of steel band and Brake drum to realize braking, and braking moment is big, and is safe and reliable, compact structure and efficient height.
Description of drawings
Fig. 1 is that one of figure cuts open in the axial office of the utility model.
Among the figure: 1-cross shaped joint, 2-tensioning bolt, 3-lever, 4-tensioning bolt, 5-axle, 6-slide bar, 7-screw, 8-spring, 9-roller, 10-Brake drum, steel band-11.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1; The utility model comprises cross shaped joint 1, tensioning bolt 2, lever 3, axle 5, slide bar 6, screw 7, spring 8, roller 9, steel band 11 and Brake drum 10; One end of steel band 11 is fixed on the slide bar with the pin (not shown), and the pin (not shown) is connected with slide bar 6 usefulness screws 7, and the other end of steel band 11 is through tensioning bolt 2 and tensioning bolt 4 outside distendings; 2 the other ends of tensioning bolt are fixing with lever 3 through axle 5; The other end of the other end of slide bar 6 and lever 3 is separately fixed at the same end of cross shaped joint 1 through axle 5, and spring 8 one ends are fixed on the lever 3, and the other end of spring 8 is fixed on an end of cross shaped joint 1 through axle 5; Three joint heads of cross shaped joint 1 all are equipped with roller 9, and roller 9 props up steel band 11 respectively.
As shown in Figure 1, after the reinforcing, lever 3 rotates around axle 5; One end of steel band 11 is fixed on an end of cross shaped joint 1 with the pin (not shown); The other end of steel band 11 is adjacent to the inner side surface of driving wheel 10, thereby realizes braking through tensioning bolt 2 and tensioning bolt 4 fixing outside distendings.
The process that the utility model is braked is following:
1, an end of steel band 11 is fixed on an end of cross shaped joint 1 with pin, and the other end of steel band 11 is through tensioning bolt 2 and tensioning bolt 4 fixing outside distendings;
2, cross shaped joint 1 and roller 9 prop up steel band;
3, regulate the size of braking force with screw 7 and slide bar 6;
4, after the reinforcing, lever 3 rotates around axle 5, makes steel band 11 be adjacent to the inner cylindrical surface of Brake drum 10, realizes braking;
5, spring 8 resets lever 3.
