Embodiment 1

[0023] as attached figure 1 , 2 As shown, a large and medium-sized surface hole arc door fixed winch hoist includes a frame 3, a double-duplex reel 4 installed on the frame 3, a power device 8, a large speed ratio reduction device 9, and a reduction device 9 Link to each other with the pinion gear 10 of the transmission device, the pinion gear 10 meshes with the bull gear 5 , and the double-duplex reel 4 is hinged with the bull gear 5 . The double-duplex reel 4 has two double-gang groups, and each double-gang group is equipped with a steel wire rope, and two double-gang groups need to be equipped with two steel wire ropes. Two pulleys are set on the spreader 1, and a wire rope 2 is respectively bypassed on each pulley, and the two ends of the wire rope 2 are respectively fixed on the two ends of each double group of the double-duplex reel 4 after bypassing the pulley. The spreader 1 is connected with the lifting lug of the arc door.

[0024] as attached image 3 As shown, ...

Embodiment 2

[0029] as attached Figure 4 , 5 As shown, removing the coupling (6) and the intermediate shaft (7) of Embodiment 1, it can be used as a fixed winch hoist for a large surface hole arc door with a single lifting point.

[0030] Other parts of this embodiment are basically the same as those of Embodiment 1, and will not be repeated here.

Embodiment 3

[0032] as attached Figure 6 As shown, the reduction device is a small speed ratio reduction device (12), and an open gear reduction device (13) is added, and a height sensor is arranged at the pinion shaft end.

[0033] Other parts of this embodiment are basically the same as those of Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a medium- and large-sized fixed winch hoist for spillway radial gates, and provides the medium- and large-sized fixed winch hoist for spillway radial gates in order to overcome the shortages of the prior art, which is simple in structure, small in occupied machine room space, light in weight, compact in distribution, high in applicability and high in safety. According to the technical scheme, the medium- and large-sized fixed winch hoist for spillway radial gates comprises a frame, a power device, a reduction device and a transmission device, at least one duplex drum or a plurality of duplex drums are mounted on the frame, each duplex drum is provided with a steel wire rope, each steel wire rope passes around a pulley on a corresponding hanger, and then two ends of the steel wire rope are fixed to two ends of each duplex drum. The medium- and large-sized fixed winch hoist for spillway radial gates has the advantages of simple structure, small occupied machine room space, light weight, compactness in distribution, and high safety.

Description

technical field [0001] The invention relates to a fixed winch hoist for an arc door, in particular to a fixed hoist hoist for a medium and large surface hole arc door. Background technique [0002] The fixed winch hoist is mainly used for opening and closing gates, and has been widely used in water conservancy and hydropower projects. The fixed hoist hoist that is used for the opening and closing of the surface hole arc door at present mainly consists of a frame, a reel fixed on the frame, a speed reduction device, a wire rope and the like. [0003] The shortcomings of the traditional single-rope design are mainly manifested as follows: [0004] 1. Due to the use of single-connected drums, one section of the steel wire rope is fixed to the drum, and the other section is directly connected to the lifting lug of the gate. In terms of door opening capacity), the diameter of the steel wire rope and the diameter of the drum are relatively large, which takes up a lot of space in...
