Description

Technical Field

[0001] This invention relates to a windshield braking device. Background Technology

[0002] Generator units typically require a damper braking device. Existing damper braking devices are formed by threaded connections of pipes, valves, and solenoid valves. During long-term use, the following problems exist: (1) The solenoid air valves have serious air leakage issues due to long operating times. There are air leaks in the pipe joints and valves of the damper control system, and there are also cross-contamination issues between pipes, which requires repeated air replenishment during the damper reset process, increasing the workload of operators. (2) There are many manual valves in the pipes. If the valve opening and closing positions are incorrect, it can cause the damper to lift up during unit operation in severe cases. (3) The damper control system has low reliability and sensitivity, requiring operators to manually operate the damper. (4) The damper braking device is formed by threaded connections of pipes, valves, and solenoid valves, which is complex in structure, cumbersome in operation, and difficult to maintain and replace parts. Summary of the Invention

[0003] To address the above shortcomings, the purpose of this invention is to provide a convenient and easy-to-operate air brake device.

[0004] The specific technical solution of the present invention to solve the above-mentioned technical problems is as follows: it includes a brake, pipelines and a control system, characterized in that it includes an integrated board, an electromagnetic air valve, a manual valve and a hand-operated valve, wherein the electromagnetic air valve, the manual valve and the hand-operated valve are mounted on the integrated board, the manual valve is connected to the main air source and is connected to the electromagnetic air valve through a pipeline, the electromagnetic air valve is connected to the hand-operated valve through a pipeline, and the hand-operated valve is connected to the brake through a pipeline.

[0005] Furthermore, the electromagnetic air valve includes a brake solenoid valve, which is connected to a first hand-operated valve via a pipeline, and the first hand-operated valve is connected to the brake chamber of the brake.

[0006] Furthermore, the electromagnetic air valve also includes a reset solenoid valve, which is connected to a second hand-operated valve via a pipeline, and the second hand-operated valve is connected to the reset chamber of the brake.

[0007] Furthermore, the brake includes a brake chamber, a piston, and a brake plate, as well as a detection system and a limiting device. The limiting device cooperates with the piston to limit the piston's stroke. The detection system can detect the wear of the brake plate, and the limiting device can adjust the brake plate according to its wear so that it cooperates with the braking components of the generator set.

[0008] Furthermore, the limiting device includes a bolt, which is threadedly connected to the cylinder of the brake. The bottom of the bolt is provided with a buffer part, which cooperates with the piston to limit the movement. The bottom of the bolt is provided with a gear, which is driven by a motor. When the detection system inputs the detected brake plate wear amount to the control system, the control system controls the motor to drive the gear to rotate. After the bolt rotates, it changes the relative position between the buffer part and the piston, so that when the piston and the buffer part cooperate, the brake plate cooperates with the braking assembly of the generator set.

[0009] Furthermore, the cylinder body is provided with a T-shaped pad, and a stop block is provided above the T-shaped pad. The stop block is detachably fixed to the cylinder body. The stop block is provided with a threaded hole that engages with a bolt, and the T-shaped pad and the bolt are sealed together.

[0010] The brake includes a braking chamber and a return chamber, and the limiting device includes a hydraulic damper, which is mounted on the cylinder and its position is adjusted by adjusting the amount of oil in the hydraulic damper.

[0011] Furthermore, a bracket is connected to the brake plate, and a detection device is installed on the bracket, which can detect the wear condition of the brake plate.

[0012] Furthermore, the detection device employs one of the following: a distance sensor, a displacement sensor, an ultrasonic transducer, or a mechanical displacement detection device.

[0013] Furthermore, the mechanical displacement detection device includes a reference component connected to the brake support plate. The reference component moves synchronously with the brake support plate to synchronously react to the stroke of the brake piston. The reference component has a rack, which meshes with a stroke monitoring component. The stroke monitoring component includes a gear and an encoder connected to the gear. The encoder is connected to a control unit. The control unit is used to receive the gear rotation signal, calculate the wear amount at the upper end of the brake, and output a brake status feedback signal.

[0014] Beneficial technical effects of the present invention: The present invention provides a windshield braking device that adopts a plate-type connection form, integrating all control elements and all air pipelines on an integrated plate to achieve pipeline-free connection. The arrangement of each control element is compact and reasonable, with small size, reliable sealing performance, and convenient operation and maintenance. It can automatically or manually apply the brake and release pressure, and realize centralized control.

[0015] In a specific embodiment of the present invention, a limiting device and a brake plate wear detection device are also provided. The two work together. When the detection device detects that the brake plate wear has reached a certain level, the control system controls the limiting device to adjust so that the brake plate and the brake assembly of the generator set can better cooperate for braking.

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] Reference Figures 1 to 5As shown, a windshield braking device of the present invention includes a brake 1, pipelines, and a control system. The control system includes an integrated plate 2, an electromagnetic air valve 3, a manual valve 4, and a hand-operated valve. The electromagnetic air valve 3, manual valve 4, and hand-operated valve are mounted on the integrated plate 2. The manual valve 4 is connected to the main air source and is connected to the electromagnetic air valve 3 through a pipeline. The electromagnetic air valve 3 is connected to the hand-operated valve through a pipeline, and the hand-operated valve is connected to the brake 1 through a pipeline. In this embodiment, the electromagnetic air valve 3 includes a brake solenoid valve, which is connected to a first hand-operated valve 5 through a pipeline. The first hand-operated valve 5 is connected to the brake chamber 8 of the brake 1. The electromagnetic air valve 3 also includes a reset solenoid valve, which is connected to a second hand-operated valve 6 through a pipeline. The second hand-operated valve 6 is connected to the reset chamber 9 of the brake 1. The device can be controlled manually or automatically. During braking, air from the main air source enters the pipeline and passes through the electromagnetic air valve 3 and the first hand-operated valve 5 into the brake chamber 8, pushing the piston 7 to move. The support plate above the piston 7 causes the brake plate to contact the braking components of the generator set, achieving rapid braking. After the generator rotor comes to a complete stop, the brake chamber 8 is vented, and compressed air enters the return chamber 9 to push the piston 7 back to its original position. This embodiment replaces the threaded connections of pipelines, valves, and solenoid valves with plate-type connections, integrating all control components and all air pipelines onto the integrated plate 2, achieving pipeline-free connections. The dynamic seal adopts an automatic compensation structure. The arrangement of each control component is compact and reasonable, with small size, reliable sealing performance, and convenient operation and maintenance. Automatic or manual braking and pressure release can be implemented, achieving centralized control.

[0020] In the above embodiments, reference is made to Figures 2 to 4As shown, the brake 1 includes a brake chamber 8, a piston 7, a brake plate 18, and a limiting device 10. The limiting device 10 cooperates with the piston 7 to limit the stroke of the piston 7 and prevent the piston 7 from having an excessive stroke under high pressure. In actual operation, to avoid wear on the unit's braking components, the brake plate 18 is often made of a material with lower hardness. Therefore, the brake plate 18 will wear during braking. After significant wear, the stroke of the piston 7 is limited by the limiting device 10, resulting in insufficient contact pressure between the brake plate 18 and the unit's braking components, which affects the braking effect. This embodiment includes a detection system that can detect the wear condition of the brake plate. The limiting device 10 can adjust according to the wear condition of the brake plate 18 to ensure better cooperation between the brake plate 18 and the generator set's braking components. In Embodiment 1, the limiting device 10 includes a bolt 11, which is threadedly connected to the cylinder of the brake 1. A buffer portion is provided at the bottom of the bolt 11, which cooperates with the piston 7 for limiting. A gear 12 is provided at the bottom of the bolt 11, driven by a motor. When the detection system inputs the detected wear amount of the brake plate 18 to the control system, the control system controls the motor to drive the gear 12 to rotate a predetermined amount. After the bolt 11 rotates, the relative position of the buffer portion and the piston 7 changes, that is, the position of the buffer portion is adjusted upwards by a certain length, so that when the piston 7 cooperates with the buffer portion, the brake plate and the braking assembly of the generator set can also achieve better cooperation. Although a threaded seal can be formed between the bolt 11 and the cylinder, the impact between the piston 7 and the buffer portion will still have some impact. In one modified embodiment, a T-shaped pad 13 is provided in the cylinder body, and a stop block 14 is provided above the T-shaped pad 13. The stop block 14 is detachably fixed to the cylinder body. The stop block 14 and the cylinder body can be fixed by bolts 11 or by threads. The stop block 14 has a threaded hole to mate with the bolt 11. There is no thread between the bolt 11 and the T-shaped pad. A dynamic seal is formed between the T-shaped pad 13 and the bolt 11, and a sealing ring can be provided on the sealing surface between them. (See reference...) Figure 5 As shown in Embodiment 2, the brake 1 includes a braking chamber 8 and a return chamber 9, and the limiting device 10 includes a hydraulic buffer. The hydraulic buffer is mounted on the cylinder body, and its position is adjusted by adjusting the amount of oil in the hydraulic buffer.

[0021] In the above embodiment, the brake 1 is equipped with a detection device 15, which can detect the wear condition of the brake plate. (Refer to...) Figure 1As shown, a mechanical displacement detection device includes a reference assembly connected to the support plate 19 of the brake 1. The reference assembly moves synchronously with the support plate of the brake 1 to synchronously react to the stroke of the piston 7 of the brake 1. The reference assembly has a rack 16, which meshes with a stroke monitoring assembly. The stroke monitoring assembly includes a gear and an encoder connected to the gear. The encoder is connected to a control unit, which receives the gear rotation signal, calculates the wear amount at the upper end of the brake, and outputs a brake status feedback signal. The reference assembly includes a limiting base, which is clamped around the bottom periphery of the brake 1 to fix the position of the limiting base. The limiting base can also be fixed to the base of the brake 1 by bolts. The two structures are selected according to the actual installation situation. The limiting base has a limiting cavity, in which a telescopic reference plate is limited and connected. The upper end of the telescopic reference plate is connected to the support plate of the brake 1 by bolts 11. The telescopic reference plate includes a first reference plate with a vertical slot. A second reference plate is slidably connected to the vertical slot. The bottom of the second reference plate is limited within the limiting cavity. The rack 16 is distributed on the first reference plate. The ranging sensor is embedded in the center hole at the top of the second reference plate. The sensor's transmitting end faces vertically towards the inner top wall of the vertical slot in the first reference plate. The receiver is a reflective reflector, attached to the inner top wall of the vertical slot in the first reference plate and coaxially arranged with the laser ranging sensor. It is used to reflect the laser signal to achieve the sliding measurement of the first reference plate relative to the second reference plate. The aforementioned detection device 15 can also be one of a distance sensor, a displacement sensor, or an ultrasonic transducer. A bracket is connected to the support plate, and the detection device is mounted on the bracket.
