Abstract

The invention discloses a shaft sinking winch steel wire rope overload rope breaking protection system. The system comprises a head sheave, a tension sensor, a steel wire rope, a shaft sinking winch and a brake control system. Loads are connected through the tail end of the steel wire rope. The steel wire rope penetrates through the tension sensor and is wound on a shaft sinking winch roller. The steel wire rope bypasses the head sheave. The head end of the steel wire rope is also fixed to the shaft sinking winch roller. A shaft sinking winch control system is connected with the shaft sinking winch brake system, a shaft sinking winch motor and the steel wire rope tension sensor. According to the protection system, a steel wire rope breaking protection device and an electronic control system and the brake system of a shaft sinking winch hoisting system are organically combined, the structure is simplified, the cost is lowered, the steel wire rope is prevented from being snapped due to overloading, and protection of the steel wire rope is achieved.

Description

technical field [0001] The invention relates to the field of engineering construction safety automatic protection, in particular to an overload protection system for a drilling winch steel wire rope. Background technique [0002] A large number of sinking winches are used in shaft construction. Generally, there are more than a dozen winches for each shaft construction, and the corresponding suspension wire ropes are also more than a dozen. However, there is currently no effective protection for shaft suspension wire ropes. It can be said that there is no protection. The motor of the winch has short-circuit and overload protection. As we all know, the current of the motor at startup is 4-7 times of the working current. If it starts with load, its current will be larger, and the overload protection is an inverse time-delay protection. It can work only after the time is overloaded, and the protection cannot be implemented in a short period of time. The suspension wire rope of ...
