review

The DLBZ electronic mechanical wheel edge brake consists of a micro motor, a reduction transmission device, an electromagnetic retainer with one-way check and separation functions, a ball screw amplitude, a cam force increasing mechanism, a spring brake cylinder, a brake caliper, and an electronic control system.

The micro motor drives the ball screw amplitude compression spring to release the brake, and the electromagnetic retainer maintains an open state. By controlling the electromagnetic retainer to release the compression spring, the brake caliper is closed.

During operation, the deceleration transmission device is driven by a micro motor to output thrust from the ball screw, and the braking spring force is eliminated through a cam force increasing mechanism to open the brake caliper.

After opening, the motor stops working and is reversed by the electromagnetic retainer reverse deceleration transmission device to maintain the open state.

When braking, the electromagnetic retainer is energized to engage and disengage the retainer, causing the deceleration transmission device to reverse. The compressed brake spring force causes the brake caliper to brake, producing a braking effect.

The windproof device adopts an electronic mechanical drive mechanism, which can easily meet various windproof requirements of the equipment through automated control, and has excellent windproof effect.

main features

• Small size, compact structure, easy installation, high protection level, long service life;
• The structure of using a micro motor to drive the ball screw amplitude as the driving device has a large braking force and accurate and rapid action. And there are no signs of aging of oil pipes, seals, or wear of hydraulic components; No oil leakage (beneficial for environmental protection), weakness, jamming or other malfunctions;
• When releasing the brake, the micro motor has a short working time and low power; Electromagnetic retainers can achieve one-way reverse and separation functions, and the brake does not require energy consumption when releasing the brake for a long time, with low energy consumption during braking and significant energy savings;
• Through the automation control system with Siemens logo as the core, it can achieve functions such as long-term release of braking, frequent starting of braking, automatic delayed braking of parking electronics, emergency windproof braking, paired release of automatic windproof braking at each point, and delayed braking in case of power failure. It can be applied to various windproof working conditions of large lifting equipment.
• The wheel edge brake uses high-performance semi metallic friction pads to form a friction pair with the side of the wheel rim. The material has good environmental adaptability, stable friction coefficient, and very stable friction performance and windproof braking effect;
• Multiple wheel brakes can be installed on a single device to provide the entire machine with high wind resistance;
• It can achieve the function of dynamic emergency braking in emergency situations that cannot be achieved by track action windproof devices such as electric anti climbing devices and rail clamps. And it has a point-to-point paired release function to reduce the impact on the equipment during emergency braking.
• Various self-locking protection functions can be achieved through electronic control. Functions such as automatic braking, manual braking, system online interlocking and centralized control controlled by devices such as anemometers and speed sensors;
• It has single manual opening and manual braking functions, and is easy to operate;
• Each wheel brake is individually controlled by the system for easy monitoring and troubleshooting.

Note:

• Point by point paired release: refers to multiple wheel side brakes on the same device being able to brake in batches according to the set braking point position and delay time sequence. Generally, it can be switched on in two to three batches, with a delay time of 2-10 seconds.
• Power outage delay braking: refers to the ability to release in pairs point by point through the backup power supply carried by the control system itself when the power supply is cut off. And it will not cause significant impact on the equipment by simultaneously applying all wheel brakes during a power outage.
• When operating a large crane, keeping the wheel brakes in a released state for a long time is beneficial for releasing the dynamic load stress on the crane wheels. The interlocking of the wheel brake control signal with the anemometer signal and emergency stop signal can improve the automatic windproof capability of the equipment.
