Constant-pressure friction driving trolley of hanging type hoisting equipment and method

Abstract

The invention relates to the technical field of hoisting equipment, and discloses a constant-pressure friction driving trolley of hanging type hoisting equipment and a method. The constant-pressure friction driving trolley comprises a hanging type trolley bearing device and a hanging type trolley driving device, wherein the hanging type trolley bearing device hung on a running rail is fixedly connected with the hanging type trolley driving device and is formed by connecting end beams clamped on two sides of the running rail with guide wheel devices and bearing wheel devices which are arranged on the end beams. Friction of running wheels is not related to the hoisting weight, the gravity and the stress, and the friction driving force of the running wheels is only related to pressure of a spring instead of being related to stress of a girder; therefore, the wheels run synchronously, and a phenomenon of rail gnawing is avoided; the service life of a motor is well prolonged; the constant-pressure friction driving trolley is small in size, light in mass, high in bearing capacity and anti-abrasion; and the problem of large noise during running is completely solved; and constant driving force is guaranteed.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a constant-pressure friction-driven operating trolley and a method for suspension-type hoisting equipment. Background technique [0002] At present, with the development and manufacture of multi-pivot cranes, this product of our company is very popular. Moreover, the domestic demand for multi-pivot cranes is increasing. Our company pays more attention to the perfection and improvement of this series of multi-pivot products. There are certain problems in the production, manufacture, sales and use of multi-pivot cranes. In order to make this product better respond to the market and better serve the society, our company continues to innovate and cooperate with us on the basis of this multi-pivot Improvement has finally produced a new type of more competitive new multi-fulcrum driving vehicle. [0003] The structure of the old-fashioned multi-pivot driving trolley is as f...

AI Technical Summary

Problems solved by technology

[0003] The structure of the old-fashioned multi-pivot driving trolley is as follows: figure 1 As shown: the entire trolley is suspended above the lower flange of the trolley running track 14, wherein the running drive reducer 12 and the motor 5 are assembled through the driving wheel 15 of the open gear structure driving part, and the passive wheel 16 and the driving wheel 15 are respectively fixed on the On the active and passive wall panels, the lower parts of the active and passive wall panels are connected together by bolt shafts, the two ends of the bolt shaft are fixed with slotted nuts, the shaft sleeves are fixed on the bolt shafts, and the shaft sleeves are installed on the end beam of the cart. The load is transmitted to the running wheels through the bushings, bolt shafts, and wall panels. Therefore, this structure has caused three defects in the old-fashioned multi-pivot crane: 1. It is not perfect in terms of uniform force on each wheel. In the case of uniformity, it is easy to gnaw the rail, which will cause excessive heat generation of the motor and affect the life of the motor

2. Because the old-fashioned structure is that the end beam is hung under the trolley, the main beam is hung under the end beam, and the hoist is hung under the main beam, the upper limit of the trolley is very large, so that it cannot meet the needs of customers in some occasions

3. Due to the large span of the crane, many wheels and long running distance, the noise during operation is very loud
