DETAILED DESCRIPTION

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] The embodiments of the present application provide brakes for the main motor and the rolling input shaft of the rolling mill, thereby solving the problem that the existing brakes for the main motor and the rolling input shaft of the rolling mill mainly use pneumatic tire clutch brakes, which are not conducive to the compact layout of the equipment, have low mechanical efficiency, are prone to slippage, and affect the stable operation of the rolling mill.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] The utility model discloses a brake for the main motor and the rolling input shaft of the rolling mill. Figure 1-4 As shown, it includes a brake base 1 and a brake housing 5 arranged on the brake base 1;

[0027] The brake base 1 is provided with a plurality of fixing holes, and the plurality of fixing holes facilitate the use of bolts to fix the brake base 1 at a target position, thereby ensuring good stability of the entire device.

[0028] A clutch 2 is provided on the brake base 1, a power output shaft 3 and an input shaft body 4 are provided on the clutch 2, a brake disc 41 is provided on the input shaft body 4, and the brake disc 41 is provided inside the brake housing 5;

[0029] Hydraulic cylinders 51 are provided on both sides of the brake housing 5. A piston rod 511 is provided inside the hydraulic cylinder 51. The end of the piston rod 511 passes through the brake housing 5 and is connected to a brake clamp 52. The brake disc 41 is located between the two sets of brake clamps 52.

[0030] A cover plate 53 is movably engaged with the brake housing 5 , and a locking assembly 6 for locking the position of the brake housing 5 is provided on the cover plate 53 .

[0031] The brake used for the main motor and the rolling input shaft of the rolling mill is an improvement on the original pneumatic clutch brake. The original brake occupies a large space, has low mechanical efficiency, and is prone to slipping when the compressed air pressure is unstable. Now the clutch 2 and the brake housing 5 are connected in series as one. The clutch 2 facilitates the control of the connection status of the power output shaft 3 and the input shaft body 4 to achieve power transmission or interruption. The brake housing 5 facilitates the braking of the input shaft body 4, and under the action of hydraulic pressure, a good braking effect is guaranteed.

[0032] The present invention integrates a clutch 2 and a brake housing 5 in series between the power output shaft 3 and the input shaft body 4 of the rolling mill motor. This design has the following advantages:

[0033] When the mill needs to be started or the rolling speed needs to be adjusted, clutch 2 connects the main motor power output shaft 3 to the rolling input shaft body 4, transmitting torque. Due to the high efficiency and stability of hydraulic transmission, clutch 2 can complete the connection quickly and accurately, ensuring the normal operation of the mill.

[0034] When the mill needs to be stopped or emergency braking is required, the brake housing 5 uses hydraulic pressure to brake the rolling input shaft body 4. The brake housing 5 can quickly respond and generate sufficient braking torque to quickly stop the mill and ensure the safety of equipment and personnel.

[0035] The clutch 2 and the brake housing 5 are connected in series as one, and can easily realize the switching between clutch and brake. During the rolling mill operation, the clutch 2 and the brake housing 5 internal states can be adjusted as needed at any time to meet different process requirements.

[0036] A positioning column 54 is provided on the brake housing 5, and the locking assembly 6 includes a hollow seat 61 fixedly connected to the cover plate 53. The positioning column 54 is movably clamped in the interior of the hollow seat 61. A locking hole 541 is opened on the positioning column 54, and a locking rod 63 is provided in the interior of the hollow seat 61. The locking rod 63 is movably inserted into the locking hole 541; the interior of the hollow seat 61 is slidably connected to a slider 62 for supporting and limiting the locking rod 63, and a spring 64 is fixedly connected between the two groups of sliders 62.

[0037] The device facilitates the assembly and disassembly of the cover plate 53 and the locking assembly 6, thereby facilitating the maintenance of the internal brake clamp 52 and ensuring stable braking of the input shaft body 4.

[0038] When installing the cover 53, first pull the slider 62 so that the slider 62 drives the locking rod 63 to move and squeezes the spring 64. At this time, dock the cover 53 with the brake housing 5, and at the same time, engage the hollow seat 61 with the positioning column 54. After it is fully engaged, release the slider 62. The spring 64 resets and pushes the slider 62 and the locking rod 63 to move, so that the locking rod 63 is inserted into the locking hole 541, thereby locking the cover 53. When it is necessary to disassemble the cover 53 and the brake clamp 52, the operation can be reversed to the above installation process.

[0039] The hydraulic cylinder 51 is connected to a hydraulic pipe 512 , which is used to connect the hydraulic cylinder 51 with an external hydraulic system to provide hydraulic power.

[0040] A docking block 513 is fixedly connected to the piston rod 511, and a slot 521 is provided on the brake clamp 52. The docking block 513 is clamped in the slot 521. The brake clamp 52 and the docking block 513 are clamped and fixed with bolts. Therefore, the brake clamp 52 is easy to disassemble and assemble at the end of the piston rod 511 and easy to maintain.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
