As further improvement of the utility model, two cambered surface brake shoe are hinged respectively at the middle part of left and right brake arm.
The utlity model has following advantage:
1. simple in structure, easy to use, cost is lower.When the push rod rise was braked, relative slight counterclockwise rotation took place with the left end of connecting lever in the flex point of connecting lever, thereby spurs and make simultaneously right brake arm top to be moved to the left to the right on pull bar.Top with left brake arm when pull bar moves right spurs to the right, thereby the top of left and right sides brake arm is moved inward simultaneously, and promotes two brake shoe and hold Brake drum tightly and realize braking.Left and right sides brake arm is in transmission connection by pull bar, connecting lever and left and right connecting plate simultaneously, between connecting lever, pull bar, left and right sides brake arm and left and right sides connecting plate, formed an irregular quadrilateral that holds Brake drum that is in transmission connection mutually, therefore can make and realize left and right sides brake arm synchronous braking preferably, avoid occurring stopping partially or brake shoe and the floating phenomenon of pasting of Brake drum, prolong the working life of friction plate and Brake drum, reduce maintenance and user cost.Because the flex point of connecting lever is extended left and is provided with manual control lever, can when needs are manually controlled, pull down and start controlling rod, brake easy to operate ground of realization function thereby drive arrestment mechanism.
2. because the left end of manual control lever is provided with tow rope, therefore can realize the function of remote manual braking.
3. owing on two brake shoe, be respectively equipped with the adjustment bolt, the end that the adjustment bolt is positioned at the brake shoe intrados cooperates with the friction plate roof pressure, therefore just can regulate matching gap between friction plate and the Brake drum by adjusting two adjustment bolts, in use keep the best fit gap between friction plate and Brake drum always, and make friction plate circular arc and Brake drum concentric, thereby make the utility model keep best working state always.
Since being in transmission connection between pusher and connecting lever be in transmission connection for open type, be that pusher is braked Brake drum by the driving mechanism that comprises connecting lever when powering up, therefore when not braking, need not power up by pusher, so just reduced the energy consumption of pusher, realize the function of economize on electricity.
5. two cambered surface brake shoe are hinged respectively at the middle part of left and right brake arm, and are simple in structure, help left and right brake arm synchronous braking, can reduce the length of left and right brake arm simultaneously, saved manufacture cost.
