Problems solved by technology

[0003] Nowadays, hoist hoist and hydraulic hoist are widely used in gate hoist. Among them, hoist hoist has large size and heavy weight. The steel wire rope is easy to rust when immersed in water, and the accuracy is not enough. The closing stability is poor, and it is troublesome to install when there are many pulleys and wire ropes; the hydraulic hoist has high requirements for the working environment, and the hoist room must be kept clean and dry to prevent oil pollution. The processing cost is high, and when the sealing quality is poor, the hydraulic oil is easy to leak
[0004] At present, there is no hoist that uses gear meshing to drive the kinematic pair to directly open and close the gate.

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0024] Such as Figure 1 to Figure 3 As shown, a gear meshing drive hoist, including a mechanical system and a drive system. The mechanical system includes a pier column 1, a load bar 2, a connecting frame 3, a box body 4, a hydraulic motor 5, a driving gear 6, a driven gear or a rack 7, a driving bracket 8, a guide wheel 9 and a roller 10. The bearing rod 2 is connected with the pier column 1 by a moving pair, that is, the bearing rod 2 can move left and right in the groove of the pier column 1; the connecting frame 3 and the bearing rod 2 are connected by a rotating pair The connecting frame 3 is fixed on one end of the box body 4; the hydraulic motor 5 is located inside the box body 4, and ...

Abstract

The invention provides a gear engagement driving hoist which comprises a mechanical system and a driving system. The mechanical system comprises a pier stud, a bearing rod, a connection frame, a box body, hydraulic motors, driving gears, a driven gear or rack, a driving support, guide wheels and a rolling wheel. The bearing rod is connected with the pier stud in a sliding pair mode. The connection frame is connected with the bearing rod in a rotary pair mode. The driving gears are located at the bottom of the box body and engaged with the driven gear. The driven gear or rack is fixed to the top of a gate. The guide wheels are located below the driving gears and on the two sides of the driven gear or rack. The invention further provides a control method of the gear engagement driving hoist. According to the driving system, the hydraulic motors are adopted for driving a gear engagement movement pair to achieve gate hoisting, precise gate hoisting control can be achieved, the hoist mechanism is effectively simplified, the occupied space is reduced, the structure weight is reduced, different degrees of hoisting capacity and stroke can be achieved, and therefore gate hoisting application in various projects at present is achieved.

Description

technical field [0001] The invention relates to a gear meshing drive hoist and a control method thereof, belonging to the technical field of hoist. Background technique [0002] In recent years, with the expansion of the construction scale of water conservancy and hydropower projects, the hoists of water conservancy projects are developing towards large-scale and special hoists. Technology is facing more and more challenges, so how to effectively reduce the self-weight of the hoist, improve the service life and reduce the consumption of raw materials needs to be solved urgently. [0003] Nowadays, hoist hoist and hydraulic hoist are widely used in gate hoist. Among them, hoist hoist has large size and heavy weight. The steel wire rope is easy to rust when immersed in water, and the accuracy is not enough. The closing stability is poor, and it is troublesome to install when there are many pulleys and wire ropes; the hydraulic hoist has high requirements for the working envir...
