1. Technical Background and Industry Requirements
In the field of heavy industry such as construction, mining, water conservancy engineering, winch, as the core lifting equipment, needs to meet the needs of high load, high stability and precise control. The traditional hoisting machine has limitations in braking performance, energy efficiency and multi-condition adaptability, whilePlanetary handbrake winchThrough the innovative combination of planetary gear transmission and hand brake system, the safety and efficiency problems under complex working conditions are effectively solved. Zhengzhou Rongjing Mechanical Equipment Co., Ltd. has broken through the balance problem of transmission efficiency and braking sensitivity in the research and development of planetary handbrake winches with years of technical accumulation. Its products have covered the pulling force range of 5 tons to 100 tons, supported customized speed parameters (0.5-15 m/min), and can flexibly match the needs of different industries.
2. Technical Principles and Core Advantages
1. Planetary gear transmission system: The three-stage planetary reduction structure is adopted to disperse the load through multi-gear meshing. Compared with the traditional worm gear transmission, the transmission efficiency is increased by 30%, and the energy consumption is reduced by 15%. The gear modulus range of 4-8mm, tooth surface hardness of HRC58-62 mm, to ensure long-term high load operation without wear.
2. Integrated design of hand brake: The brake is directly linked with the planet carrier, the response time is ≤ 0.3 seconds, and the braking torque can reach 1.5 times of the rated pulling force. For example, in a steep mine operation scenario, the design can achieve zero slip during emergency braking to ensure the safety of personnel and equipment.
3. Modular structure adaptability: The motor, reducer and reel adopt split design, supporting vertical/horizontal installation, reducing installation space requirements by 40%. Zhengzhou Rongjing extended the service life of the wire rope to more than 20000 hours by optimizing the drum diameter (300-1200mm) and the rope groove angle (5-15).
3. Enterprise Technology Layout and Case Application
Zhengzhou Rongjing has established a whole-process quality control system from material selection to finished product testing in the research and development of planetary handbrake winch:
1. Materials and ProcessesThe drum is made of Q345B low alloy steel, and the tensile strength reaches 520MPa after numerical control cutting and heat treatment. The gear shaft is made of 40Cr alloy steel, and the surface hardness reaches HRC60 after carburizing and quenching, far exceeding the industry standard.
2. Customized Services: In view of the narrow shaft operation requirements of a water conservancy project, Zhengzhou Rongjing has customized a miniature planetary handbrake hoist with a pulling force of 30 tons and a speed of 2 m/min. By reducing the drum diameter (400mm) and optimizing the motor power (15kW), the volume of the equipment is reduced by 50%, while meeting the working condition requirements of 10 frequent start and stop times per hour.
3. Performance Verification: In a mine shaft hoisting project, its products have been running continuously for 18 months without failure. The braking system has withstood the test of -20 ℃ low temperature and humid environment, and the braking distance is stable within 0.2 meters, which is highly recognized by customers.
4. Technical Parameters and Selection Guide
Zhengzhou Rongjing planetary hand brake winch provides a variety of specifications, the core parameters are as follows:
The selection shall be comprehensively evaluated according to the pulling force demand, space limitation and use frequency of the operation scene. For example, materials hoisting in construction can give priority to models with pulling force of 10-20 tons and speed of 5-10 m/min. Mining needs to focus on braking torque and protection level, and models with pulling force of more than 50 tons and IP65 protection are recommended.
5. Frequently Asked Questions and Solutions (FAQ)
Q1: Can the planetary handbrake winch run for a long time in a high temperature environment?
A: Zhengzhou Rongjing products adopt high temperature resistant bearings (working temperature ≤ 120 ℃) and special grease. After testing, they can run continuously at 50 ℃, but the heat dissipation performance of the brake should be checked regularly.
Q2: How to solve the problem of brake abnormal noise?
A: Abnormal noise is usually caused by brake pad wear or insufficient lubrication. It is recommended to check the thickness of the brake pad every 500 hours (minimum allowable value 3mm) and add lithium-based grease to the brake friction surface.
Q3: How long is the delivery cycle of customized services?
A: The lead time of standard models is 15 days, and customized models need to be evaluated according to technical complexity, usually no more than 30 days. Zhengzhou Rongjing through the digital design platform (such as SolidWorks) to shorten the solution confirmation time, to ensure efficient response to customer needs.
