Detailed ways

As shown in Figures 1 and 2, a light and small electric wire rope hoist arranged on the guide rail 1 of a crane includes an electric trolley 2 and a lifting mechanism 3. The guide rail 1 can be a box-shaped guide rail 1 or an I-shaped guide rail 1 . Lifting mechanism 3 comprises suspension hook 33, the reel 32 that lifts suspension hook 33 by winding or output wire rope 35, is used to drive the lifting power mechanism 34 of reel 32, and lifting power mechanism 34 can be directly motor, also Can be combined with reducer etc.

The electric trolley 2 includes a trolley frame 21 whose length extends along the front-to-rear direction and is located directly below the guide rail 1, driving wheel sets 22 and driven wheel sets 23 arranged on the front and rear sides of the trolley frame 21, for driving the driving wheels The trolley power mechanism 24 of group 22, the driving wheel group 22 and the driven wheel group 23 are hung on the guide rail 1. Similarly, the trolley power mechanism 24 can be directly a motor, or can be combined with a reducer.

The driving wheel group 22 includes a driving group driving wheel and a driving group driven wheel that are hung on the left and right sides of the guide rail 1, and the driven wheel group 23 includes two driven wheels that are respectively hung on the left and right sides of the guide rail 1. The trolley power mechanism 24 outputs and drives the driving wheel of the active group.

The trolley frame 21 is fixed with a reel stand 31, and the reel 32 is fixed on the reel stand 31 and is located directly below the guide rail 1, and the hook 33 is located directly below the reel 32, which avoids the problem of weight imbalance and does not require Using counterweights reduces the weight deceleration by half. The wire rope 35 output by the reel 32 is directly exported downwards and bypasses the pulley above the suspension hook 33 , and its end is fixedly connected with the reel frame 31 . The fixed pulley is omitted, so that the lifting speed is twice as fast as that after passing through the fixed pulley.

The lifting power mechanism 34 is fixed on the roll stand 31 and is located on one side of the vertical plane where the guide rail 1 is located. The light and small wire rope electric hoist also includes a control mechanism 4 fixed on the winding frame, and the control mechanism 4 is located on the other side of the vertical plane where the guide rail 1 is located.

In the present embodiment, the guide rail 1 is a traveling I-beam. That is, the I-shaped guide rail 1 further reduces the volume of the light and small wire rope electric hoist.

Lifting operation: when the lifting operation command is pressed, the control mechanism 4 controls the lifting power mechanism 34 of the lifting mechanism 3 to run, and the output torque of the motor is decelerated by the reducer to increase the torque, driving the reel 32 to rotate, so that the hoisting The weight on the hook 33 lifts vertically and moves.

Horizontal running: when the horizontal motion command is pressed, the control mechanism 4 controls the trolley power mechanism 24 to run, and the driving wheel set 22 and the driven wheel set 23 move on the guide rail 1, so that the hoisting weight moves in the front and rear length direction of the guide rail 1.

As mentioned above, we have fully described according to the purpose of the utility model, but the utility model is not limited to the above-mentioned embodiment and implementation method. Practitioners in the relevant technical fields can make different changes and implementations within the scope permitted by the technical ideas of the present utility model.
