Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of detection devices, in particular to a torque detection device for a large-torque hydraulic brake. Background Art
[0002] The braking torque of large hydraulic brakes is often greater than 3000 Nm. It is difficult to detect the braking torque after assembly. The largest wrench on the market with a capacity of 500 Nm is more than 1 meter long. This method is not only limited but also easily causes the risk of the test bench tipping over. It can be seen that this type of high-torque brake cannot be directly tested with a torque wrench. Another method is to use a loading test bench for testing, but this method has low detection efficiency. The cost of making the corresponding connecting parts after changing the model is high and the test bench itself is also expensive. The overall cost of use is too high. Therefore, we propose a torque detection device for a large-torque hydraulic brake to solve the above problems. Utility Model Content

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 creative efforts are within the scope of protection of the present invention.
[0016] See also Figure 1 A high-torque hydraulic brake torque detection device includes a brake body 1, a transition flange 2 is fixedly connected to the top of the brake body 1 by bolts, a transition connecting shaft 3 is installed in the middle of the brake body 1, the transition connecting shaft 3 is connected to the transition flange 2 by insertion, the transition connecting shaft 3 is removably connected to a planetary torque-increasing support 6, the planetary torque-increasing support 6 is fixedly installed on the transition flange 2 by connecting bolts 7, a planetary torque-increasing part 4 is installed above the planetary torque-increasing support 6, the planetary torque-increasing part 4 is connected to the transition connecting shaft 3 through gear transmission, an input connecting square hole 5 is fixedly installed on the top of the planetary torque-increasing support 6 by bolts, a high-precision torque sensor is arranged inside the input connecting square hole 5 for real-time monitoring of torque changes during braking.
[0017] By connecting the transition flange 2 to the planetary torque-increasing part 4 and transmitting torque through the transition shaft 3, the torque wrench value connected to the input connection standard square hole 5 can be observed. This value multiplied by the speed ratio of the planetary part can be used to obtain the torque value of the brake. In order to adapt to different brakes, this can be achieved by replacing the transition flange 2 and transition shaft 3.
[0018] During the specific implementation process, it is first necessary to ensure that the connection between the transition connection flange 2 and the transition connection shaft 3 is firm and reliable to ensure the stability of torque transmission. At the same time, the material selection of the transition connection flange 2 and the transition connection shaft 3 is also crucial. High-strength and wear-resistant materials should be used to ensure that they are not easily damaged during use. In order to adapt to different brakes, this can be achieved by replacing the transition connection flange 2 and the transition connection shaft 3. This means that users can choose appropriate transition connection flanges 2 and transition connection shafts 3 according to actual needs to achieve the best torque transmission effect. This flexibility makes the design widely applicable to various types of brakes.
[0019] In addition, when the size of the transition connection flange 2 does not meet the requirements, the adaptation can be completed by replacing the planetary torque increase part support 6. This means that even if a special installation situation occurs, the problem can be solved by adjusting the support, thereby ensuring the adaptability and reliability of the entire system.
[0020] In summary, the high-torque hydraulic brake torque detection device reduces the required input torque through the characteristics of the planetary reducer, thereby using a smaller and more convenient torque wrench to read the brake torque value. It can also be adapted to more types of brakes by simply replacing the connecting flange and connecting shaft, and the replacement cost is lower and more convenient.
