Description

Technical Field

[0001] This utility model relates to the field of winch-type gate opener technology, and in particular to a novel winch-type gate opener. Background Technology

[0002] A winch-type gate hoist is a specialized opening and closing device for operating fast-acting gates. Fast-acting gates are used to protect generator units or steel pipes. Normally suspended above the orifice, they can quickly cut off water flow in the event of a generator, pump, or pipe malfunction, preventing the accident from escalating. The closing time of the fast-acting gate should meet the protection requirements for the generator unit and steel pipe; generally, the hoist should be able to close the gate within 2 minutes. To prevent damage to the gate's bottom edge and sill from violent impacts, the fast-acting winch-type gate hoist should be equipped with a speed limiting device, restricting the gate's descent speed near the sill to within 5 m / min. However, there are no speed restrictions during the descent process, as long as it does not damage the hoist's components.

[0003] The steel ropes on winch gate openers need to be oiled regularly. Working in harsh environments, rust and wear can severely impact the service life of steel ropes. Therefore, oiling is essential. Oiling prevents rust and wear, extending the service life of the steel ropes.

[0004] However, in the existing technology, oil is usually applied manually to the rope drum of the winch. This not only poses certain safety hazards, but also makes it difficult to evenly coat the steel rope surface with lubricating grease. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of winch-type gate opener, which solves the problem that manual lubrication cannot be evenly applied to the surface of the steel rope during maintenance of conventional new winch-type gate openers.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model provides a novel winch-type gate opener, including a winch body, a steel rope for lifting the gate, and an oiling mechanism disposed at the bottom of the winch body for brushing oil onto the steel rope.

[0008] The oiling mechanism includes a support plate disposed at the bottom of the winch body, an oiling drum disposed on the support plate, a motor disposed on the support plate and driving the oiling drum to rotate, and a peristaltic pump and an oil injection pipe for providing lubricating oil to the oiling drum; wherein an oil storage tank for providing lubricating oil is also disposed on the support plate; wherein the steel rope passes through the oiling drum and extends to the bottom of the support plate, and an oiling brush is disposed inside the oiling drum.

[0009] In this embodiment, symmetrical limiting grooves are provided on the support plate, and a slider is slidably provided in the limiting groove. The oiling drum is provided on the slider through a bearing. This facilitates the use of a motor to drive the oiling drum to rotate, thereby achieving uniform application of lubricating grease to the surface of the steel rope during the rotation process.

[0010] Furthermore in this embodiment, the lower end of the oiling drum extends through the bottom of the limiting slide groove, and its upper end is provided with a rotating outer drive wheel or sprocket; thereby facilitating transmission with the motor.

[0011] Furthermore in this embodiment, the inner diameter of the oiled drum is larger than the outer diameter of the steel rope, which facilitates the passage of the steel rope and the change of the position of the steel rope on the drum.

[0012] Furthermore in this embodiment, a drive wheel or sprocket is provided on the power output shaft of the motor.

[0013] Furthermore, in this embodiment, a telescopic cylinder is also provided on the support plate, and a support is provided at the telescopic end of the telescopic cylinder. A tension wheel or sprocket is provided on the support via a bearing.

[0014] In this embodiment, the tensioning wheel, the outer drive wheel, and the driving wheel are driven by a transmission belt. Alternatively, they can be connected by a sprocket and a chain.

[0015] Furthermore in this embodiment, the oil injection pipe is connected to the oil storage tank through the oil delivery pipe, and a peristaltic pump is installed on the oil delivery pipe. The oil injection pipe is installed above the oiling drum through a bracket.

[0016] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0017] In this invention, the winch body drives the steel rope to rise and fall during the winding of the rope drum, thereby using an oiling mechanism to apply oil to the surface of the steel rope as it passes through, thus achieving regular maintenance and upkeep of the steel rope. Additionally, a telescopic cylinder is installed on the support plate, and a support is mounted on the telescopic end of the cylinder. A tension wheel is mounted on the support via a bearing, and the tension wheel effectively drives the oiling drum. Attached Figure Description
