The specific embodiment is as follows:

in order to clearly illustrate the technical features of the present solution, the present utility model will be described in detail below with reference to the following detailed description and the accompanying drawings.

As shown in fig. 1, the fixed hoist of weight box comprises a gate pier 1, a gate 2 arranged in the gate pier 1 and a frame bridge 3 arranged above the gate pier 1, wherein a power winding drum 4 is arranged on the frame bridge 3, the power winding drum 4 can be fixedly arranged on the frame bridge 3 through a bracket, a first steel wire rope 5 and a second steel wire rope 6 are positioned on the power winding drum 4 and reversely wound, the first steel wire rope 5 and the second steel wire rope 6 can be one steel wire rope or two steel wire ropes, the middle position of the power winding drum 4 is fixed, the two sides of the power winding drum 4 are reversely wound, the free end of the first steel wire rope 5 is fixedly connected with the gate 2, the free end of the second steel wire rope 6 is fixedly connected with a fixed pulley block 9 arranged on the frame bridge 3 after bypassing a movable pulley block 8 of a lifting head 7 in the water surface direction of the gate 2, and the weight box 10 is connected below the lifting head 7.

The weight box 10 is a sealed box, and sand materials are arranged in the sealed box to increase the gravity.

The top of the weight box 10 is provided with a lifting basket 11, the top of the lifting basket 11 is provided with a lifting lug 12, and the lifting lug 12 is connected with a hook at the bottom of the hanging head 7 through a rotating shaft 13.

The side of the weight box 10 is provided with rollers 14, the gate pier 1 is vertically provided with guide rails 15 matched with the rollers 14, and the rollers 14 can move up and down along the guide rails 15 to keep the stability of up and down movement.
