Abstract
A brake shoe position following device of a brake comprises a cylinder barrel, a position following rod, position following springs and a fixed shaft, and is characterized in that two rectangular position following springs are placed in an inner cavity of the cylinder barrel, the position following springs are separated by a spring separation seat, and an upper cover of a sleeve is in threaded connection with an opening end port of the cylinder barrel; one end of the position following rod penetrates through the upper cover of the sleeve to be inserted into the inner cavity of the cylinder barrel and is in threaded connection with the spring spacer in the cylinder barrel, and the other end of the position following rod is in threaded connection with the fixed shaft; the cylinder barrel is provided with a mounting hole and is fixed on the brake rack through a bolt, and the fixed shaft is inserted into and fixed on the mounting seat on the brake shoe. The utility model discloses a brake shoe of stopper is along with when position device uses, is in the state of opening the brake when the wheel limit stopper, guarantees through adjusting along with the position pole that two along with the position spring's resultant force equals with brake shoe self resistance to guarantee that brake shoe and walking wheel are in the parallel state, guarantee that the clearance of opening the brake is even, and stop the liner and wear out unusually, it has characteristics such as simple structure, regulation convenience simultaneously.
Description
Technical Field
The utility model relates to a stopper field specifically is a brake shoe of stopper is along with position device.
Background
The hydraulic caliper disc brake and the wheel brake are widely applied to various cranes in ports, and the brake shoe following device on the brake mainly ensures that the brake shoe can not float and cling to a brake disc or a travelling wheel due to self gravity, vibration and the like when the brake is opened. In the prior art, most of the position following devices are connected between the brake shoe and the mounting bracket through a U-shaped spring, and the free rotation of the brake shoe is limited by the elastic force of the U-shaped spring. Because the elasticity of the U-shaped spring is certain, the brake shoe can not be in a proper position in an actual working condition, and the brake shoe and the brake frame are often ineffective due to too large resistance, so that the brake shoe and the traveling wheel are in a splayed shape or an inverted splayed shape when the wheel side brake is opened, and a liner is easily rubbed to the brake disc or the traveling wheel when the brake is opened, thereby causing the abnormal abrasion of the liner.
Disclosure of Invention
The utility model aims at providing a simple structure, regulation convenience can guarantee that the gap of opening the floodgate is even, stop the brake shoe of the stopper of liner unusual wearing and tearing along with the position device.
The utility model discloses a brake shoe position following device of a brake, which comprises a cylinder barrel, a position following rod, a position following spring and a fixed shaft, and is characterized in that two rectangular position following springs are placed in an inner cavity of the cylinder barrel, the position following springs are separated by a spring spacer, and an upper cover of a sleeve is in threaded connection with a port at the opening end of the cylinder barrel; one end of the following rod penetrates through the upper cover of the sleeve to be inserted into the inner cavity of the cylinder barrel and is in threaded connection with the spring spacer in the cylinder barrel, and the other end of the following rod is in threaded connection with the fixed shaft and is tightened and prevented from loosening through a tightening nut; the cylinder barrel is provided with a mounting hole and is fixed on the brake rack through a bolt, and the fixed shaft is inserted into and fixed on the mounting seat on the brake shoe.
The utility model discloses a brake shoe of stopper is along with when position device uses, is in the state of opening the brake when the wheel limit stopper, guarantees through adjusting along with the position pole that two along with the position spring's resultant force equals with brake shoe self resistance to guarantee that brake shoe and walking wheel are in the parallel state, guarantee that the clearance of opening the brake is even, and stop the liner and wear out unusually, it has characteristics such as simple structure, regulation convenience simultaneously.
