Problems solved by technology

[0003] In the traditional winch structure, the output shaft of the motor is directly connected to one end of the reel, and the stress point of the output shaft is the connection between the end of the output shaft and the reel, and the weld seam is easy to break when the load is heavy
Since the winch is the main lifting equipment in small and medium-sized mines, once an accident occurs, it will affect the production of the whole mine, and even cause the shutdown of the whole mine and casualties

Embodiment 1

[0025] Such as figure 1 As shown, the drawworks for drilling includes a driving motor 1, an output shaft 2, a connecting arm 3, a reel 4, an inner rotating shaft 5 and a steel cable 8, one end of the output shaft 2 is connected to the power output end of the driving motor 1, and the inner rotating shaft 5 Sleeved on the output shaft 2, the connecting arm 3 evenly and vertically passes through the axis of the inner rotating shaft 5, the inner wall of the sleeve 4 is connected with the connecting arm 3, and the steel cable 8 is fixed on the reel 4. The driving motor 1 drives the reel 4 to rotate through rotation, and the reel 4 releases or recovers the steel cable 8, thereby realizing the hoisting effect of the winch.

Embodiment 2

[0027] Such as figure 1 As shown, the above-mentioned connecting arms 3 are multiple and all pass through the axis of the inner rotating shaft 5, and are connected to the inner wall of the reel. Setting a plurality of connecting arms 3 can share the force applied to the reel 4 as much as possible. With a small force, the winch is not easy to break between the motor and the reel under heavy load, which improves the service life of the winch and saves costs.

Embodiment 3

[0029] Such as figure 1 with figure 2 As shown, on the basis of Embodiment 1, this embodiment also includes a base 6 and two fixing seats 7, the drive motor 1 is fixed on the base 6, and the two fixing seats 7 are relatively arranged on the base 6, and the Both ends of the reel 4 are rotatably fixed on the fixed seat 7 , and there is a gap between the reel 4 and the base 6 . The reel 4 rotates on the fixed seat 6 .

Abstract

The invention discloses a drilling winch comprising a motor, an output shaft, a plurality of connecting arms, a reel, and an inner rotary shaft. One end of the output shaft is connected with the power output end of a drive motor. The output shaft is sleeved with the inner rotary shaft. The connecting arms evenly and vertically pass the axial center of the inner rotary shaft. The inner wall of a sleeve is connected with the connecting arms. One end of a cable is connected to the reel. The reel is hollow, the connecting arms are connected to the inner rotary shaft and also connected with the inner wall of the reel, and accordingly a motor output shaft is stressed evenly and the risk of breakage of the end part of the output shaft, in contact with the reel, is reduced. The force applied to the reel is dispersed by the connecting arm; the force applied to the reel is even decomposed into micro parts by the connecting arms; accordingly, the motor and the reel rarely break from each other when the winch operates under high load, the service life of the winch is prolonged, and the cost is saved.

Description

technical field [0001] The invention relates to a winch for drilling, in particular to a winch for drilling with balanced force. technical background [0002] Winch, a light and small lifting device that uses a reel to wind a wire rope or chain to lift or pull heavy objects, also known as a hoist, can be used alone or as a component in machinery such as lifting, road construction and mine lifting, because it is easy to operate , large amount of rope winding, convenient displacement and wide application. [0003] In the traditional winch structure, the output shaft of the motor is directly connected to one end of the reel, and the stress point of the output shaft is the connection between the end of the output shaft and the reel, and the weld seam is easily broken when the load is heavy. Since the winch is the main lifting equipment in small and medium-sized mines, once an accident occurs, it will affect the production of the whole mine, and even cause the shutdown of the wh...
