Description

Technical Field

[0001] The utility model relates to the field of spraying tools, in particular to a lubricating oil spraying device for a crane wire rope. Background Art

[0002] Overhead crane is an important tool in the production process. With the help of steel wire rope, various heavy objects are moved and adjusted in position during the production process. In frequent production work, it is necessary to spray lubricating oil on the steel wire rope. Because the lubricating oil has a certain viscosity, and the steel wire rope of the overhead crane is large in size and needs to be coated with a large area, it is difficult to complete the spraying work with a general spray pot. Often, the staff manually applies the lubricating oil to the steel wire rope. During the coating process, the overhead crane workers apply the lubricating oil unevenly, the lubricating oil is thick, and the grease has high viscosity. After the steel wire rope has been running for a period of time, the grease falls down in a ball, which not only wastes the lubricating oil but also pollutes the ground. At the same time, the hands of the overhead crane workers are easily squeezed when lubricating the steel wire rope, which poses a certain safety risk. Therefore, a lubricating oil spraying device is needed, which can effectively replace manual work to complete the spraying work, and at the same time, the structure is simple and easy to manufacture. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a crane wire rope lubricating oil spraying device, which can effectively spray the wire rope, reduce labor and reduce the risk of pinching hands, and ensure that a thin oil film is sprayed and all adheres to the wire rope, and no oil will fall down to pollute the ground environment.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a crane wire rope lubricating oil spraying device, including a spraying pipe, the rear end of the spraying pipe is connected to an oil storage barrel containing lubricating oil, a ventilation hole is opened on the spraying pipe, a blowing pipe mounting sleeve is provided on the outer side of the spraying pipe, an inclined through hole is provided on the wall of the blowing pipe mounting sleeve, the through hole is connected to the ventilation hole, a blowing pipe is provided in the through hole, and a compressed air storage tank is provided at the rear end of the blowing pipe.

[0005] A further improvement of the technical solution of the utility model is that an internal thread is arranged in the through hole, an external thread matching the internal thread is arranged on the outside of the blowing pipe, and the blowing pipe can be fixed in the through hole by the mutual engagement of the internal and external threads.

[0006] A further improvement of the technical solution of the utility model is that rubber sealing rings which are closely fitted with the spraying pipe are arranged at both ends of the blowing pipe installation sleeve.

[0007] A further improvement of the technical solution of the utility model is that: a blowing pipe clamp is sleeved on the blowing pipe, a spraying pipe clamp is sleeved on the spraying pipe, and a connecting chain is arranged between the blowing pipe clamp and the spraying pipe clamp.

[0008] A further improvement of the technical solution of the utility model is that a screen is provided at the tail end of the spray pipe to block foreign matter in the lubricating oil.

[0009] The further improvement of the technical solution of the utility model is that the outer diameter of the spray pipe is 25 mm, the inner diameter is 20 mm, and the ventilation hole is 10 cm away from the nozzle of the spray pipe.

[0010] Due to the adoption of the above technical scheme, the technical progress achieved by the utility model is: by obliquely inserting a blow pipe connected to a compressed air storage tank into the spray pipe, high-pressure air can be introduced into the nozzle of the spray pipe. Due to the Bernoulli fluid principle, the flow rate is large and the pressure is small, and the negative pressure caused will suck up the lubricating oil at the end of the spray pipe. The sucked up lubricating oil will be dispersed into mist when it encounters high-pressure air and sprayed out from the nozzle with the wind, forming an oil film attached to the wire rope. By setting a blow pipe installation sleeve, the installation of the spray pipe and the blow pipe can be made more convenient, and it is also convenient to disassemble and store. At the same time, it is more convenient to replace the spray pipe during a long spraying process. By setting a pipe clamp with a connecting chain, the disassembled spray pipe and the blow pipe can be connected and stored, which is not easy to be lost in a messy production site, and it will not be difficult to spray due to missing parts during assembly.

[0014] The present invention is further described in detail below in conjunction with the embodiments:

[0015] like Figure 1The figure shows a schematic diagram of the structure of a crane wire rope lubricant spraying device, including a main spray pipe 1, the spray pipe 1 has an outer diameter of 25 mm, an inner diameter of 20 mm, and is about two meters long. The tail end of the spray pipe 1 is passed into the oil storage barrel 7, and the oil storage barrel 7 is filled with No. 320 lubricant. A screen 12 for blocking foreign matter in the lubricant is provided at the tail end of the spray pipe 1 to filter the lubricant preliminarily. A ventilation hole 21 is provided 10 cm from the mouth of the spray pipe 1. A blow pipe installation sleeve 2 is provided near the ventilation hole 21 outside the spray pipe 1. Wedge-shaped rubber sealing rings that fit tightly with the spray pipe 1 are provided at both ends of the blow pipe installation sleeve 2, which ensure the air tightness in the installation sleeve on the one hand, and the stability of the installation on the other hand. The wall of the blow pipe installation sleeve 2 is solid, and a through hole 3 is provided on the wall of the pipe, which is inclined downward from the outside to the inside. The position of the through hole 3 is opposite to the ventilation hole 21, that is, the through hole 3 is connected to the ventilation hole 21. A blow pipe 4 is provided in the through hole 3, and the outer diameter of the blow pipe 4 is 10 mm. The tail end of the blow pipe 4 is connected to a compressed air storage tank 6. When the compressed air storage tank 6 is opened, high-pressure air can be blown into the ventilation hole 21 through the blow pipe 4 and enter the spray pipe 1. The specific connection method in this embodiment is that an internal thread is provided in the through hole 3, and an external thread is provided on the outside of the blow pipe 4. The internal and external threads are adapted to each other, and the blow pipe 4 is fixed by screwing into the through hole 3 with the help of the internal and external threads meshing with each other.

[0016] A blowing pipe clamp 41 is provided on the blowing pipe 4, a spray pipe clamp 11 is provided on the spray pipe 1, and a connecting chain 5 is provided between the blowing pipe clamp 41 and the spray pipe clamp 11. When spraying is not needed, the device can be disassembled for storage. The connecting chain can ensure that the spray pipe and the blowing pipe are always together and will not be lost in a messy production site, thereby ensuring the completeness of the device.

[0017] When in use, open the switch valve of the compressed air storage tank 6, the high-pressure air is released, enters the ventilation hole 21 through the blowing pipe 4 and then enters the inside of the spray pipe 1. Because of the Bernoulli principle, the high-pressure air will cause the flow rate of the fluid inside the spray pipe 1 to accelerate, and then the pressure becomes smaller, causing negative pressure. The external air pressure in the oil barrel will press the lubricating oil into the spray pipe 1. When the lubricating oil hits the high-pressure air, it will be dispersed into mist, and sprayed out from the pipe mouth with the high-pressure wind, forming an oil film attached to the wire rope, completing the spraying of the lubricating oil on the crane wire rope. On the one hand, the utility model has a simple structure and low cost. The spray pipe and the blowing pipe used can be directly used on site and are easy to make. On the other hand, the spraying method can effectively replace manual application, that is, it changes the laborious working method of the crane worker, saves about 50% of lubricating oil, and the wire rope is sprayed evenly, with good lubrication effect. A thin oil film is sprayed, all attached to the wire rope, and no oil will fall down to pollute the ground environment. Since a certain safe distance is maintained from the drum when the oil is sprayed, the safety factor is improved to a certain extent when lubricating all wire ropes.

[0018] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
