Description

Technical Field

[0001] The utility model belongs to the technical field of winch type door openers, and in particular relates to a double-brake winch type door opener. Background Art

[0002] The forebay gate in a hydropower station is an important part of the construction of a hydropower station. Its function is to brake and hold the gate so that it can be reliably suspended in the air. It is the first line of defense for the penstock of a hydropower station, and also the last line of defense after a failure of the turbine generator set governor and the water inlet gate. It can ensure that the water source is cut off in time when an accident occurs, and minimize the possibility of secondary accidents. The brake is an important component in the winch hoist to ensure safe operation. Short-stroke electromagnetic shoe brakes are widely used in winch hoists.

[0003] The existing double-brake winch type gate hoist still has some defects. Most of them are not accurate enough and cannot accurately control the height of the gate lifting. They are inconvenient to use and reduce the service life of the device. For this reason, we propose a double-brake winch type gate hoist. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. Through the limit plate, infrared transmitter, infrared receiver, gravity sensor and alarm, the infrared receiver can receive the signal emitted by the infrared transmitter. Each time it receives the signal, it means that the winch drum rotates one circle, so that the number of circles of the winch drum can be accurately controlled, and then the lifting height of the gate can be controlled, which is more convenient to use.

[0013] 2. The box, turbine, motor and worm are used to provide power for the rotation of the winch drum. The motor is started to drive the worm to rotate, thereby driving the turbine to rotate, and then driving the winch drum to rotate, so as to achieve the winding of the chain.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3The utility model provides a technical solution: a double-brake winch type gate hoist, comprising a fixed frame 1 and a winch drum 2, a winch drum 2 is provided on the inner side of the fixed frame 1, the winch drum 2 and the fixed frame 1 are rotatably connected, a limit plate 3 is provided at one end of the winch drum 2, the limit plate 3 and the winch drum 2 are fixedly connected, an infrared transmitter 4 is provided on one side of the limit plate 3, the infrared transmitter 4 and the limit plate 3 are fixed by screws, an infrared receiver 5 is provided on the inner side of the fixed frame 1, the infrared receiver 5 and the infrared transmitter 4 are electrically connected, a gravity sensor 6 is embedded on the surface of the winch drum 2, an alarm 7 is provided on one side of the fixed frame 1, and the alarm 7 and the fixed frame 1 are fixed by screws.

[0020] In this embodiment, when the double-brake winch type gate opener is used, the winch drum 2 rotates to collect the chain, thereby lifting the valve. When the winch drum 2 rotates, it drives the limit plate 3 to rotate, thereby driving the infrared transmitter 4 to rotate. The infrared receiver 5 can receive the signal emitted by the infrared transmitter 4. Each time it is received, it means that the winch drum 2 rotates one circle, so that the number of circles of rotation of the winch drum 2 can be accurately controlled, and then the lifting height of the gate can be controlled, which is more convenient to use. Through the gravity sensor 6, when the device fails and the chain breaks, the data of the gravity sensor 6 changes. At this time, the alarm 7 will start to alarm, reminding the staff to deal with it in time, which is safer to use.
