Problems solved by technology

[0005] The purpose of the present invention is to design a new valve-controlled liquid-filled coupling in view of the deficiency of the background technology, adopting a double working chamber composed of a turbine and a pump wheel in the coupling housing, and setting a filling and draining control valve , the liquid filling volume of the coupling is controlled by the controller, so that the high-power conveyor can realize the no-load start and soft start of the motor, so as to solve the problems of difficult starting, unbalanced load and overload protection of the high-power conveyor

Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing:

[0026] figure 1 , 2 , 3, 4, 5, and 6 are the overall structure diagram, the position and connection relationship of each part must be correct, and the installation should be firm.

[0027] The left and right boxes can be made of stainless steel, which should have good strength and corrosion resistance.

[0028] This structure has no bearing support, and there is no problem of bearing corrosion.

[0029] The fluid paths of filling and draining should be unimpeded and clean without being blocked.

[0030] Set the temperature and filling volume sensors to effectively grasp the temperature and filling volume information of the working chamber, which is used to control the filling volume of the working chamber and monitor the temperature.

[0031] The left part of the coupler is connected by the conveyor motor shaft extending into the coupler shaft sleeve, and the right part...

Abstract

The invention relates to a valve control liquid-filled coupler of a high-power conveyor. A main structure comprises a left-right box body, a left-right ring flange, a liquid filling valve, a drain valve, a switching valve, a motor input shaft sleeve, a speed reducer connecting sleeve, a turbine, a pump wheel, a temperature sensor, a filling amount sensor and a controller. The design of combining the left-right box body, the turbine and the pump wheel with input output is used, a rotor composed of the pump wheel and the turbine is arranged in the box body to form a double-working chamber structure, filling amount is controlled by the liquid filling valve and the drain valve, the filling amount sensor and the temperature sensor transmits information so as to effectively increase transmission power and perform overload protection, and the high-power conveyor can completely realize no-load start and the slow start of the conveyor. The coupler has advanced and reasonable design, compact structure, safety, stability, reliability, convenient installation and use, high power and small volume, can use water and oil for filling, and is a quite ideal driving device of the high-power conveyor.

Description

technical field [0001] The invention relates to a valve-controlled liquid-filled coupling for a high-power conveyor, which belongs to the technical field of design and manufacture of coal mine transportation equipment parts. Background technique [0002] In coal mines, scraper conveyors and belt conveyors are often used for coal transportation, collectively referred to as conveyors. High-power scraper conveyors and belt conveyors have difficulties in starting, unbalanced operating loads, and lack of effective overload protection. Difficulty in starting. The commonly used starting devices include friction torque limiter, torque limiting hydraulic coupling, frequency conversion speed regulation and controllable planetary differential speed reducer, etc. Frequency conversion speed regulation is rarely used because of its high price, and it is often used in motors and gear reducers. A torque-limiting hydraulic coupling is installed between the torque-limiting hydraulic couplings...
