Description

Technical Field

[0001] The utility model relates to the technical field of disc brakes, in particular to a disc brake which is easy to assemble and disassemble. Background Art

[0002] At present, the brake is a device with the function of slowing down, stopping or keeping the moving parts (or moving machinery) in a stopped state. It is a mechanical part that stops or slows down the moving parts in the machinery. It is commonly known as brakes and gates. The brake is mainly composed of a frame, brake parts and operating devices. Some brakes are also equipped with automatic adjustment devices for the clearance of brake parts. In order to reduce the braking torque and structural size, the brake is usually installed on the high-speed shaft of the equipment, but large equipment with higher safety requirements (such as mine hoists, elevators, etc.) should be installed on the low-speed shaft close to the working part of the equipment.

[0003] Among them, when the disc brake is repaired or replaced, it is necessary to dismantle the entire brake, such as the spring, friction plate, brake oil pump, etc., and then install the new brake disc so that the disc brake can be used normally.

[0004] Then, when carrying out maintenance, the disassembly process becomes extremely cumbersome, which greatly increases the workload and increases the risk of installation errors. For this reason, a new technical solution needs to be designed to solve the problem. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disc brake that is easy to disassemble and assemble, comprising a brake caliper body, a frame is fixedly mounted on one side of the bottom of the brake caliper body, a brake disc is rotatably mounted on the other end of the frame, a mounting groove is opened in the middle of the top of the brake caliper body, and a quick disassembly mechanism is installed in the mounting groove;

[0007] The quick-disassembly mechanism includes a spreader plate inserted on both sides of the installation groove, a cover detachably installed on the top of the installation groove, a limit slide groove opened in the middle of both sides of the cover, a limit slider slidingly installed in the two groups of the limit slide grooves, a first spring fixedly installed on one side of the two groups of limit sliders, a second docking groove opened in the middle of the two groups of limit sliders, and bolts threadedly installed at the four corners of the cover, and the four groups of bolts are respectively threadedly installed on the top of the brake caliper body.

[0008] As an optional solution of the technical solution of the present application, the two groups of the second docking grooves respectively fit together with the tops of the two groups of brake discs, and the other sides of the two groups of the first springs are respectively fixedly installed on the inner walls of the two groups of limiting slide grooves, which can support the limiting slide blocks.

[0009] As an optional solution to the technical solution of the present application, an oil inlet is connected and installed in the middle of one side of the brake caliper body, and pistons are movably installed on both sides of the bottom of the brake caliper body. The two groups of pistons correspond to the two groups of brake discs respectively, and the brake discs can be squeezed.

[0010] As an optional solution of the technical solution of the present application, piston cylinders are fixedly installed on both sides of the bottom of the brake caliper body, and positioning mechanisms are installed in the two groups of piston cylinders.

[0011] As an optional solution of the technical solution of the present application, the positioning mechanism includes a piston plate movably installed in the piston cylinder, a first docking groove opened on one side of the piston plate, a second spring fixedly installed on one side of the outer wall of the piston plate, and docking blocks fixedly installed on both sides of the brake plate, which can position the bottom of the brake disc.

When the cover is closed on the top of the installation groove, the top of the brake disc is synchronously aligned with the upper limit slider of the cover, so that when the operator controls the hydraulic oil, the pistons on both sides of the bottom of the brake caliper body will continuously squeeze the brake disc to clamp the brake disc and achieve the braking effect. Not only can the brake disc be limited to ensure that the brake disc moves left and right as a whole when it is squeezed, but the brake disc can also be quickly disassembled and assembled by disassembling and assembling the cover.

[0015] 2. The technical solution of the present application has piston cylinders fixedly installed on both sides of the bottom of the brake caliper body, and positioning mechanisms are installed in the two groups of piston cylinders. When the brake disc is being installed, the docking block at the bottom of the brake disc fits with the first docking groove on the piston plate, which not only can position the bottom of the brake disc, but also when the two sides of the bottom of the brake caliper body squeeze the brake disc, the docking blocks on both sides of the brake disc respectively fit in the first docking groove and the second docking groove, ensuring that the brake disc as a whole moves left and right synchronously, so that the side wall of the brake disc is completely in contact with the brake disc, achieving a good braking effect.
