Description

Technical Field

[0001] The utility model relates to the technical field of hoists, and specifically, to a winch hoist. Background Art

[0002] Hoists are used in various large-scale water supply and drainage, water conservancy and hydropower projects. They are used to control the lifting of various large and medium-sized cast iron gates and steel gates to achieve the purpose of opening and closing. They can be divided into hydraulic hoists, winch hoists, gantry cranes, handwheel hoists, electric hand hoists, hand-operated hoists, screw hoists, double-hanging hoists, etc.

[0003] The winch hoist is a hoisting device specifically used to operate fast gates. Fast gates are used to protect the units or steel pipes. Usually, they are suspended above the orifice. When an accident occurs to the generator, water pump or steel pipe, the water flow can be quickly cut off to avoid the expansion of the accident. The closing time of the fast gate should meet the protection requirements for the units and steel pipes. Generally, it is required that the hoist can close the fast gate within 2 minutes. At the same time, to prevent damage to the bottom edge of the gate and the bottom sill due to violent collision, a speed limiting device should be provided for the fast winch hoist to limit the descending speed of the gate when approaching the bottom sill within 5 m / min, but there is no limit requirement for the speed during the descending process as long as it does not damage the components of the hoist.

[0004] However, the commonly used winch hoist can only drive one gate to close by one kind of motor and cannot control multiple gates by one motor, resulting in the need for multiple hoists to complete the operation of multiple gates. In view of this, a winch hoist is developed. Content of the Utility Model

[0005] The utility model provides a winch hoist, which solves the problem that the winch hoist in the prior art can only drive one gate to close by one kind of motor and cannot control multiple gates by one motor, resulting in the need for multiple hoists to complete the operation of multiple gates.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0028] As Figures 1 to 3 shown, this embodiment proposes a hoisting type gate hoist, including

[0029] a fixed top frame 1, and a driving box 2 is arranged on the fixed top frame 1;

[0030] The driving and adjusting component 3 is arranged inside the driving box 2;

[0031] The driving and switching component 4 is arranged inside the driving box 2;

[0032] The driving and adjusting component 3 includes a control box 3-1. A connecting platform 3-2 is arranged on the control box 3-1. An activity hole 3-3 is formed in the connecting platform 3-2. An activity shaft 3-4 is arranged inside the driving box 2. The activity shaft 3-4 is inserted into the activity hole 3-3. A driving port 3-5 is formed at the bottom of the control box 3-1. A driving shaft 3-6 is arranged inside the control box 3-1. A driving gear 3-7 is fixedly sleeved on the driving shaft 3-6. An extension bracket 3-8 is arranged on the lower end surface of the driving box 2. A driven shaft 3-9 is arranged on the extension bracket 3-8. A linkage gear 3-10 is arranged on the driven shaft 3-9. A transmission chain 3-11 is arranged between the linkage gear 3-10 and the driving gear 3-7. The linkage gear 3-10 is meshed with a control winding wheel 3-12.

[0033] In this embodiment, the control box 3-1 can swing inside the driving box 2 through the activity shaft 3-4. After the motor drives the driving shaft 3-6 to rotate, the driving shaft 3-6 drives the driving gear 3-7 to rotate. The transmission chain 3-11 drives the linkage gear 3-10 on the driven shaft 3-9 to rotate. The meshing relationship between the linkage gear 3-10 and the control winding wheel 3-12 drives the control winding wheel 3-12 to rotate.

[0034] Specifically, the driving gear 3-7 and the linkage gear 3-10 have the same specifications, and the transmission ratio between the driving gear 3-7 and the linkage gear 3-10 is 1:1.

[0035] Furthermore, the driving and switching component 4 includes an oil cylinder platform 4-1. A driving oil cylinder 4-2 is arranged on the oil cylinder platform 4-1. A stress plate 4-3 is arranged on the connecting platform 3-2. The output end of the driving oil cylinder 4-2 is pin-connected with the stress plate 4-3. The driving oil cylinder 4-2 is pin-connected with the oil cylinder platform 4-1. An operation port 4-4 is arranged at the lower end of the driving port 3-5. A linkage shaft 4-5 is arranged inside the operation port 4-4. The control winding wheel 3-12 is sleeved on the linkage shaft 4-5. A driven gear 4-6 is sleeved on the linkage shaft 4-5. The driven gear 4-6 is meshed with the linkage gear 3-10.

[0036] In this embodiment, the driving oil cylinder 4-2 on the oil cylinder platform 4-1 can drive the control box 3-1 to swing inside the driving shaft. During the swinging process of the operation box, the linkage gear 3-10 swings accordingly. When the linkage gear 3-10 is meshed with the driven gear 4-6, it can drive the control winding wheel 3-12 to rotate, and the gate is opened and closed through the winding on the control winding wheel 3-12.

[0037] Further, sliding tracks 5 are provided on the opposite inner surfaces of the drive box 2. The drive box 2 is located within the sliding tracks 5. The number of linkage shafts 4-5 is two, and the two linkage shafts 4-5 are located on the opposite sides of the linkage gear 3-10. A positioning disk 6 is provided at the lower end of the extension frame 3-8, and the driven shaft 3-9 is arranged on the positioning disk 6.

[0038] In this embodiment, the sliding tracks 5 can enable the operation box to swing smoothly. According to the different swinging directions of the operation box, one of the two passive gears 4-6 is engaged.

[0039] Further, support stands 7 are provided at the four corners of the upper end surface of the drive box 2. The upper end surfaces of the support stands 7 are connected to the fixed top frame 1. One end of the movable shaft 3-4 is connected to the motor, and the driving shaft 3-6 and the driven shaft 3-9 are movably connected in the drive box 2 through bearings. The transmission ratio between the linkage gear 3-10 and the passive gear 4-6 is 4:3. The extension frame 3-8 is of a triangular structure and is arranged at the lower end of the drive box 2 at the drive port 3-5.

[0040] In this embodiment, the support stands 7 are used to fixedly connect the drive box 2.

[0041] When the gate needs to be opened or closed, the gate can be pulled up by winding the wire, and the wire is wound around the control wire winding wheel 3-12. The driving oil cylinder 4-2 on the oil cylinder platform 4-1 can drive the control box 3-1 to swing within the drive shaft. During the swinging process of the operation box, the linkage gear 3-10 swings accordingly. When the linkage gear 3-10 meshes with the passive gear 4-6, after the motor drives the driving shaft 3-6 to rotate, the driving shaft 3-6 drives the driving gear 3-7 to rotate, and drives the linkage gear 3-10 on the driven shaft 3-9 to rotate through the transmission chain 3-11. The control wire winding wheel 3-12 is driven to rotate through the meshing relationship between the linkage gear 3-10 and the control wire winding wheel 3-12. On the contrary, after the driving oil cylinder 4-2 drives the operation box to swing in the reverse direction, similarly, the other control wire winding wheel 3-12 is driven to rotate, achieving the purpose of paying out or taking up the wire.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
