Description

Technical Field

[0001] The invention relates to the field of electric hydraulic brakes, and in particular to an electric hydraulic brake with adjustable torque. Background Art

[0002] The existing electric hydraulic brakes are sometimes unable to meet the working requirements due to the influence of seasonal temperature and other factors, and are prone to safety accidents. The replacement of electric hydraulic brakes is cumbersome, and increases the burden of manpower, material and financial resources. The torque-adjustable electric hydraulic brake adjusts the braking torque by adjusting the length of the threaded rod to make it hinged with different torque adjustment holes. While effectively increasing the braking torque, the braking force of the spring assembly can still meet the working needs. This device is relatively easy to operate, greatly saves costs, and can meet the working needs of different working conditions. Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention provides an electric hydraulic brake with adjustable torque, which is mainly used to meet the working requirements of the electric hydraulic brake under different working conditions and reduce energy consumption.

[0004] The invention provides an electric hydraulic brake with adjustable torque, which comprises a left base, a supporting bolt, a nut, a brake drum, a left brake arm, a threaded rod, a right brake arm, a torque adjustment plate, a hydraulic pusher, a spring assembly and a right base, and is characterized in that: a torque transmission hole, a brake hole, a push hole and a plurality of torque adjustment holes are provided on the torque adjustment plate, a left thread, an adjustment component and a right thread are provided on the threaded rod, a left brake arm connecting hole is provided on the left side of the threaded rod, a torque adjustment plate connecting hole is provided on the right side of the threaded rod, a threaded rod hole, a left brake drum hole and a base hole are provided on the left brake arm, a torque adjustment plate hole, a right brake drum hole and a base hole are provided on the right brake arm, a heavy tension spring is provided inside the spring sleeve of the spring assembly, and the initial state of the heavy tension spring is a tension state, a spring pull rod is provided with a pull rod hole, a base hole is provided at the bottom of the spring assembly, a hydraulic push hole is provided on the push rod of the hydraulic pusher, a base hole is provided at the bottom end of the hydraulic pusher, a left brake arm hole and a right brake arm hole are provided on the left base, and a spring assembly hole and a hydraulic pusher hole are provided on the right base.

[0005] The threaded rod torque adjustment plate connecting hole is hinged to the right brake arm torque adjustment plate hole, the threaded rod left brake arm connecting hole is hinged to the left brake arm threaded rod hole, the left brake arm base hole is hinged to the left base left brake arm hole, the right brake arm base hole is hinged to the left base right brake arm hole, the torque adjustment plate brake hole is hinged to the spring assembly pull rod hole, the spring assembly base hole is hinged to the right base spring assembly hole, the torque adjustment plate pushing hole is hinged to the hydraulic pusher hydraulic pushing hole, and the hydraulic pusher base hole is hinged to the right base hydraulic pusher hole.

[0006] When the threaded rod is hinged to a plurality of different torque adjustment holes on the torque adjustment plate respectively, the braking torque is different. By changing the braking torque, a suitable braking torque is selected under different working conditions. When the spring assembly is braking, the braking force provided is guaranteed to complete the work needs. When the braking torque is increased, the hydraulic pusher requires less energy when releasing the brake, thereby saving energy.

[0007] When the threaded rod is hinged to multiple different torque adjustment holes on the torque adjustment plate respectively, the threaded rod needs to have different lengths, the left thread of the threaded rod is left-handed, and the right thread is right-handed. There is an internal thread inside the adjustment component, and the length of the threaded rod can be adjusted by rotating the adjustment component.

[0008] The heavy tension spring inside the spring assembly is initially in a stretched state. The heavy tension spring pulls the torque adjustment plate downward through the spring pull rod, and the braking torque is transmitted through the torque adjustment plate and the threaded rod. The left brake arm and the right brake arm move toward the middle, causing the brake drum to brake. When the hydraulic pusher works, the hydraulic push rod moves upward, thereby releasing the brake.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] By adjusting the length of the threaded rod, the threaded rod is hinged with different torque adjustment holes on the torque adjustment plate, thereby changing the braking torque of the electric hydraulic brake. When the working conditions change, the existing hydraulic brake sometimes has insufficient braking force, which cannot meet the work needs, and it is cumbersome to replace the hydraulic brake. The present invention can meet the work needs under different working conditions by changing the braking torque, so that the original braking force can still meet the work needs, and the operation is relatively simple, which greatly saves manpower, material and financial resources. Selecting the appropriate braking torque under different working conditions can reduce safety hazards during work and reduce energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to fully describe the technical content, structural features, objectives and effects of the present invention, the following will be described in detail with reference to the accompanying drawings.

[0021] A torque-adjustable electrohydraulic brake, such as Figure 1 , which includes 1. a left base, 2. a support bolt, 3. a nut, 4. a brake drum, 5. a left brake arm, 6. a threaded rod, 7. a right brake arm, 8. a torque adjustment plate, 9. an electric hydraulic pusher, 10. a spring assembly, and 11. a right base. The present invention solves the problem of cumbersome replacement of hydraulic brakes by opening a plurality of torque adjustment holes on the torque adjustment plate 8, thereby changing the braking torque and reducing energy consumption.

[0022] like Figure 2 and Figure 4 As shown, the torque adjustment plate 8 is provided with a torque transmission hole 8004, a brake hole 8005, a push hole 8006, a torque adjustment hole 8001, a torque adjustment hole 8002 and a torque adjustment hole 8003. The torque adjustment plate connecting hole 6002 of the threaded rod 6 can be hinged with the torque adjustment hole 8001, the torque adjustment hole 8002 and the torque adjustment hole 8003 on the torque adjustment plate 8. When hinged with different torque adjustment holes, the braking torque is different, and the appropriate braking torque can be selected according to different working conditions.

[0023] like Figure 5 and Figure 6 As shown, a heavy tension spring 1005 is provided inside the spring assembly 10. The heavy tension spring 1005 is initially in a stretched state, thereby generating a braking force. When the hydraulic pusher 9 is working, the hydraulic push rod 901 provides an upward push force, thereby releasing the brake.

[0024] The working principle of the torque-adjustable electric hydraulic pusher of the present invention is as follows: the heavy tension spring inside the spring assembly provides downward braking force, and the braking torque is transmitted to the left brake arm and the right brake arm through the torque adjustment plate and the threaded rod. The braking torque is changed by hinged connection of the threaded rod and different torque adjustment holes on the torque adjustment plate, so that the braking force provided by the spring assembly can meet the working requirements under different working conditions, and the hydraulic pusher can reduce energy consumption when releasing the brake.

[0025] The torque-adjustable electric hydraulic actuator of the present invention is mainly used in the sluice clamping system. Taking the sluice clamping system as an example, the sluice clamping system is greatly affected by factors such as seasonal temperature, and sometimes there will be insufficient braking force and other phenomena, which are prone to safety accidents. Replacing the electric hydraulic brake is relatively cumbersome. The present invention, by hingedly connecting the threaded rod with different torque adjustment holes, changes the braking torque, and solves the cumbersome problem of replacing the hydraulic brake. The operation is simpler and energy consumption can be reduced.

[0026] The present invention is an electric hydraulic pusher with adjustable torque. The heavy tension spring 1005 in the spring assembly 10 generates a downward braking force, and transmits the braking torque to the left brake arm 5 and the right brake arm 7 through the torque adjustment plate 8 and the threaded rod 6, so that the brake drum 4 moves toward the middle to generate braking. The threaded rod 6 is hinged with different torque adjustment holes to change the braking torque. The hydraulic pusher 9 hydraulic push rod 901 provides an upward push force to release the brake.

[0027] The present invention is a torque-adjustable electric hydraulic pusher. Since a plurality of torque adjustment holes are provided on the torque adjustment plate, the threaded rod can be hinged with different torque adjustment holes, so it is relatively easy to change the braking torque. Compared with the traditional hydraulic brake, this invention realizes torque adjustment, solves the cumbersome problem of replacing the hydraulic brake, and can reduce energy consumption.

[0028] The embodiments described above are only descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
