Problems solved by technology

[0003] For the existing channel, if the working bridge mode is used, the height of the ship will be affected. The oil cylinder generally used at present is limited by the stroke of the oil cylinder, and the opening and closing force is relatively large, and the time and cost of later maintenance are very large, so it is urgently needed. A arc-shaped driving hoist that can make structural parts rotate horizontally, is small in size, can be installed concealedly, and is labor-saving and reliable.

Embodiment Construction

[0016] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0017] like figure 1 As shown, a gear pin type hoist includes a driving device 1, a reduction device 3, a sprocket 5, a fixed support 4 and a track 6, and the reduction device 3 is connected to the fixed support 4, and the driving device 1 is mated and connected to the deceleration device 1, the driving device 1 drives the deceleration device 3, the sprocket 5 is arranged between the fixed support 4 and the track 6, the sprocket 5 is connected with the deceleration device 3, the Chain gear 5 and track 6 transmission connections.

[0018] In addition, the driving device 1 is connected with a reduction gear 3 through a coupl...

Abstract

The invention relates to a dentate hoist which comprises a driving device, a speed reducer, a chain sprocket, a fixed support and a track, wherein the speed reducer is in threaded connection with the fixed support, the driving device is in fit joint with the speed reducer, the chain sprocket is arranged between the fixed support and the track, the chain sprocket is in fit joint with the speed reducer, and the chain sprocket is rotatablely connected with the track. The dentate hoist provided by the invention has the advantages that through reducing the power driving ratio by using a long actuating arm, the horizontal rotation problem existing in triangle gates and large arc structures is solved well; and meanwhile, the dentate hoist is compact in structure, small in volume, concealed in mounting, labor-saving, energy-saving and environmentally-friendly.

Description

technical field [0001] The invention relates to a hoist, in particular to a gear pin type hoist. Background technique [0002] With the continuous improvement of the level of shipping construction, the requirements for water conservancy landscape projects are also constantly increasing. Triangular gates and horizontally rotating structural parts are increasing, miniaturized, and concealed opening and closing large-scale structural devices replace the original working bridge opening and closing mode, which is environmentally friendly and energy-saving, and reduces the need to change the original landform. [0003] For the existing channel, if the working bridge mode is used, the height of the ship will be affected. The oil cylinder generally used at present is limited by the stroke of the oil cylinder, and the opening and closing force is relatively large, and the time and cost of later maintenance are very large, so it is urgently needed. The utility model relates to a arc-...
