Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and specifically to an oil pipe cleaning tool, a cleaning device and a cleaning method. Background Art

[0002] In the manufacturing process of engines that use liquid fuel as energy, liquid pipelines are essential structural components. Taking gasoline engines as an example, hard oil pipes are required as connectors in many connecting pipelines such as between the engine and the injector, between the injector and the injection pump, and between the injection pump and the oil hose. The oil circuit is completed by combining hard oil pipes and soft oil pipes.

[0003] One of the steps in the processing of hard oil pipes is to clean the pipes. Only after cleaning can the pipes enter the subsequent production process. If the subsequent processing is carried out directly without cleaning, the pipes will be damaged. For example, when bending or piercing, the surface of the pipes needs to be smooth and free of impurities, otherwise cracking will easily occur, resulting in the scrapping of parts.

[0004] Take the diesel engine high-pressure oil pipe as an example. The size of this kind of oil pipe is usually 1.5-3.6mm inner diameter, 6-8mm outer diameter, and 150mm-900mm in length. Because the oil pipe itself is a hollow tube, both the inside and outside need to be cleaned to remove dust and impurities inside and outside the tube. The general standard for cleaning is to take each oil pipe as a unit. There are less than or equal to 1 particle with the above diameter; The diameter of the particles is controlled to be less than 2; The diameter of the particles is controlled to be less than 10. And the total amount of impurities does not exceed If there are too many impurities, not only may problems occur in the subsequent processing of the oil pipe, but it may even cause particles to enter the engine during use, causing serious damage to the engine.

[0005] Based on the above requirements, the general large-scale mixed washing cleaning equipment cannot meet the cleaning standards of the oil pipe, and the manual hand-held cleaning of a single oil pipe can meet the cleaning requirements, but it takes a long time and is not efficient. Therefore, a cleaning device that can meet the cleaning requirements of such oil pipes is needed. Summary of the invention

[0073] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Embodiment 1:

[0074] See also Figure 1 and Figure 2 , this application provides the following technical solutions:

[0075] A fuel pipe cleaning tool comprises a main positioning part 11 and a secondary positioning part 12, wherein the main positioning part 11 is provided with a plurality of first connection positions. The secondary positioning part 12 forms a surrounding structure around the main positioning part 11, and is provided with a plurality of second connection positions. When the fuel pipe 100 is connected to the cleaning tool, one end of the fuel pipe 100 is connected to the first connection position of the main positioning part 11, and the other end is connected to the second connection position of the secondary positioning part 12. After the connection is completed, the fuel pipe 100 carried by the main positioning part 11 and the secondary positioning part 12 forms a circumferential radial distribution structure centered on the main positioning part 11.

[0076] The main positioning part 11 and the auxiliary positioning part 12 can adopt a separate structural form, and the two are connected by the oil pipe 100. When the oil pipe 100 is carried, the two are combined, and when the oil pipe 100 is not carried, the two are completely separated. The main positioning part 11 and the auxiliary positioning part 12 can also be used in an integrated structural form. It is only necessary to replace the placement position originally reserved for the oil pipe 100 with two fixed rods, or to set a rod body parallel to the oil pipe 100 to connect the main positioning part 11 and the auxiliary positioning part 12. Through this structure, the oil pipe 100 can be effectively isolated so that they will not collide with each other during cleaning, thereby avoiding damage to the body of the oil pipe 100. In addition, by distributing the oil pipe 100 in a radial form, it is convenient to combine the cleaning tool and related cleaning equipment. When the tool is rotating for cleaning, the weight distribution on it is more balanced, and there is a stable tool state during rotation.

[0077] Furthermore, the main positioning part 11 includes a main fixing ring 111, which is a circular ring structure, and a plurality of through holes are provided in a circumferential array on the ring body of the main fixing ring 111, and the through holes are the first connection positions. The secondary positioning part 12 includes a secondary fixing ring 121, which is also a circular ring structure, and the radius of the secondary fixing ring 121 is greater than the radius of the main fixing ring 111. A through hole serving as a second connection position is provided on the ring body of the secondary fixing ring 121, and the second connection position corresponds to the first connection position, and the hole axis of the second connection position coincides with that of the first connection position.

[0078] This solution adopts a design that each cleaning tool can hold eight oil pipes. When in use, each oil pipe 100 passes through the second connection position and the first connection position respectively. An annular gasket can be placed in the through hole of the first connection position and the second connection position. The gasket is made of elastic material and the oil pipe 100 is fixed by the interference fit between the gasket and the oil pipe 100.

[0079] Furthermore, the cleaning tool also includes a connecting portion 13, which is located at the lower side of the main positioning portion 11 and connected to the main fixing ring 111, and is used as a docking structure between the cleaning tool and external equipment; the connecting portion 13 is driven to rotate by an external driving mechanism, thereby driving the entire cleaning tool to rotate. A top plate 112 is fixedly arranged on the upper side of the main fixing ring 111, and the top plate 112 is a circular plate coaxial with the main fixing ring 111, and the radius of the top plate 112 is greater than the radius of the main fixing ring 111.

[0080] Furthermore, the cleaning tool also includes a stop assembly 14, which is connected to the ring body of the secondary fixed ring 121; the stop assembly 14 includes a main stopper 141, which is movably sleeved on the ring body of the secondary fixed ring 121, and the outer wall of the main stopper 141 extends to one axial side of the secondary fixed ring 121 to fix a stop block 143. A secondary stopper 142 is arranged on one side of the main stopper 141, and the secondary stopper 142 is fixedly arranged on the ring body of the secondary fixed ring 121. An elastic member 144 is arranged between the main stopper 141 and the secondary stopper 142, and the two sides of the elastic member 144 are respectively fixedly connected to the main stopper 141 and the secondary stopper 142, and the elastic member 144 uses a disc spring.

[0081] Combined with the stop assembly 14, when it is necessary to stop the rotation of the cleaning tool, the corresponding mechanism can be directly used to block the moving path of the stop block 143, so that the entire cleaning tool stops. With the help of the elastic member 144 of the disc spring, the impact force generated instantly when the stop block 143 is blocked can be buffered to a certain extent, and the displacement of the disc spring when subjected to force is small, which does not affect the requirement of instantaneous stop of the cleaning tool. Embodiment 2:

[0082] See also Figures 3 to 6 The present solution also provides an oil pipe cleaning device, using the cleaning tool 1 of Example 1, and the cleaning device includes a cleaning unit 2 and a water supply unit 3. The cleaning unit 2 includes a cleaning pool 21 and a docking portion 22. The cleaning pool 21 includes a pool body 211 for placing the cleaning tool 1; the docking portion 22 is arranged in the middle area of ​​the pool body 211, and the docking portion 22 is used to be combined and connected with the connecting portion 13 of the cleaning tool 1. The docking portion 22 is linked with the driving mechanism, and the driving mechanism drives the cleaning tool 1 to rotate through the docking portion 22.

[0083] A cleaning assembly 23 is arranged in the cleaning pool 21. The cleaning assembly 23 includes a spray pipe 231 and a nozzle arranged on the spray pipe 231. A plurality of nozzles are arranged on the pipe body of each spray pipe 231. The nozzles are arranged in a linear array along the axial direction of the spray pipe 231, and the direction of the nozzles is arranged toward the cleaning tool 1 in the cleaning pool 21. The nozzles can be atomizing nozzles or high-pressure nozzles, or a combination of the two, and the purpose is to spray the cleaning liquid onto the outer wall of the oil pipe 100 through the nozzles. Generally, the cleaning liquid is a mixture of pure water obtained by a water maker and a cleaning liquid, which is filtered and reused again after use.

[0084] The water supply unit 3 includes a water supply part and a water return part. The water supply part is used to supply oil pipe cleaning water to the cleaning component 23. The water supply part includes a new water passage and a circulating water passage. The new water passage is connected to an external water source through a new water pump, and the external water source is introduced as cleaning water. The water return part is connected to the inside of the cleaning tank 21, and is provided with a purification unit 31. The purification unit 31 is used to recover the waste water after cleaning the cleaning tank 21, and transport the waste water to the circulating water passage of the water supply part after purification. A circulating pump is provided on the circulating water passage, and the circulating pump supplies the purified waste water to the cleaning component 23 again as cleaning water.

[0085] A pool cover 212 is provided on the pool body 211 of the cleaning pool 21. One side of the pool cover 212 is hinged to the edge of the pool body 211. A frame 213 corresponding to the pool body 211 is provided on the lower side of the pool cover 212. The pool cover 212 is provided with a corresponding driving unit, and the driving unit drives the pool cover 212 to open or close. When the pool cover 212 is buckled on the pool body 211, the frame 213 is close to the inner wall of the pool body 211, and the frame 213 extends to the inside of the pool body 211, so that the problem of splashing of internal water during cleaning is avoided by the frame 213.

[0086] Two spray pipes 231 are respectively arranged on the inner side of the pool cover 212 and the pool body 211; and the spray pipes 231 are arranged in parallel. When the pool cover 212 and the pool body 211 are buckled, the spray pipes 231 in the pool cover 212 and the pool body 211 are respectively located at the upper and lower sides of the cleaning tool 1. By spraying the cleaning liquid with the spray pipe 231 and the nozzle, the outer wall of the oil pipe 100 can be cleaned.

[0087] A drain port is provided at the bottom of the tank body 211, and the bottom of the tank body 211 is a concave structure, and the drain port is provided at a low level of the concave structure. The cleaning wastewater enters the wastewater pool at the bottom of the cleaning tank 21 through the drain port, and then is recycled through the purification unit 31.

[0088] The purification unit 31 includes a clean water pump 311 and a filter element group 312 connected to the clean water pump 311. The water inlet end of the clean water pump 311 is connected to the wastewater drainage pipeline of the tank body 211, and the water outlet end of the clean water pump 311 is connected to the water inlet end of the filter element group 312. The filter element group 312 is composed of a plurality of filter elements connected in series through a pipeline, and the water outlet end of the filter element group 312 is connected to the water supply part to form a circulating water passage of the water supply part. Through the filtration of the filter element group 312, the cleaning wastewater is purified for recycling and reuse. Embodiment three:

[0089] On the basis of Example 2, the cleaning unit 2 of this solution further includes a centrifugal part 24, which includes a centrifugal tube and a flow guide hood 241. The centrifugal tube is connected to the water supply part and is located in the docking part 22, and the water outlet of the centrifugal tube is arranged toward the middle of the lower side of the cleaning tool 1. Because the end of the oil pipe 100 extends to the inner side of the main fixing ring 111, the water outlet is actually arranged toward the inner area of ​​the main fixing ring 111. The centrifugal tube uses a separate pipeline for water supply, forming a water flow from bottom to top toward the middle of the cleaning tool 1.

[0090] The docking part 22 includes a driving shaft, one end of which is linked to the motor shaft of the motor, and the motor drives the driving shaft to rotate. A water outlet of a centrifuge tube is symmetrically arranged on both sides of the driving shaft. The water outlet of the centrifuge tube is connected to the pool body 211, and has no connection relationship with the driving shaft.

[0091] The middle part of the pool body 211 is slightly raised, and the horizontal position is higher than the position of the drain. A circular hole is opened in the middle part of the pool body 211 corresponding to the docking part 22, and a filter screen is fixedly arranged at the circular hole. The drive shaft is rotatably connected to the filter screen and extends to the upper side of the filter screen. A cylindrical cavity is arranged on the lower side of the filter screen, and the water outlet of the centrifuge tube is located in the cavity. A drain port is arranged on the cavity wall of the cavity, and the drain port is connected to the wastewater tank through a pipeline. The lower end of the drive shaft passes through the bottom of the cavity, and the lower end of the drive shaft is linked to the motor of the drive mechanism. The linkage method can be directly connected to the motor shaft, or linked through a gear mechanism, a sprocket mechanism, a pulley mechanism, etc.

[0092] A limiting ring 214 is provided on the upper side of the circular hole in the middle of the pool body 211, and the limiting ring 214 is rotatably connected to the lower end of the flow guide cover 241. The flow guide cover 241 is buckled on the outer side of the upper part of the driving shaft of the docking part 22, and the upper end of the flow guide cover 241 is connected to the lower side of the middle part of the cleaning tool 1. A flow guide blade is provided inside it, and the water in the centrifuge tube is guided to the middle part of the cleaning tool 1 through the flow guide cover 241, forming a water path connected to the internal cavity of the oil pipe 100.

[0093] See also Figure 2 , Figures 7 to 10 The connecting portion 13 of the cleaning tool 1 includes a plug plate 131, a plug rod is arranged at the lower side of the plug plate 131, and a plug hole is arranged on the air guide cover 241 corresponding to the plug rod, and the cleaning tool 1 is plugged into the air guide cover 241 through the plug plate 131;

[0094] Both ends of the guide cover 241 are open ends. The cavity inside the guide cover 241 is in the shape of a truncated cone. The small radius end of the cavity is connected to the lower side of the cleaning tool 1, and the large radius end is buckled on the outside of the docking portion 22; the guide blades inside the guide cover 241 are axial flow blade structures. Through the guide cover 241 of this structure, after the cleaning tool 1 is plugged into the guide cover 241, the guide cover 241 also rotates synchronously with the rotation of the cleaning tool 1. During the rotation process, the guide blades inside it form a force to guide the upper side of the guide cover 241. When the water outlet of the centrifuge tube passes through the filter, the water flow will be relatively dispersed due to the filter. After the flow is guided by the guide cover 241, on the one hand, the water flow is further guided to the upper end of the guide cover 241, that is, the small radius outlet, and the pressure of the water flow when entering the middle area of ​​the cleaning tool 1 is increased by the power of the guide blades and the change of the inner diameter of the cavity; on the other hand, the guide blades provide the water flow with an initial rotation force, which facilitates the subsequent centrifugal entry of the water flow into the oil pipe 100. Through the guide cover 241 and the centrifugal tube structure, water is introduced into the oil pipe 100 by centrifugal force, and then thrown out from the other end of the oil pipe 100, which plays a role in cleaning the inner wall of the oil pipe. Embodiment 4:

[0095] On the basis of Example 3, the cleaning unit 2 also includes a stop portion 25, which is used to instantly stop the rotating cleaning tool 1. The stop portion 25 includes a stop ring 251 and a stop drive unit 253. The stop ring 251 surrounds the outside of the cleaning tool 1 and is composed of a number of arc-shaped parts assembled into a circular ring. In this embodiment, two arc-shaped parts are provided, that is, the arc-shaped parts are semi-circular. A cushion layer 252 is provided on the side of the arc-shaped part facing the cleaning tool 1. The cushion layer 252 is used to seal the end of the oil pipe 100 and is made of elastic material. The stop drive unit 253 is connected to the arc-shaped part of the stop ring 251 to drive the arc-shaped part to move closer to or away from the cleaning tool 1. The stop drive unit 253 includes two cylinders, the fixed end of the cylinder is fixedly connected to the pool wall of the pool body 211, and the movable end is connected to the outer wall of the arc-shaped part. The cylinder pushes the arc-shaped member closer to or away from the cleaning assembly. When the arc-shaped member is assembled, the cushion layer 252 abuts against the end of the oil pipe 100 of the cleaning tool 1 and seals the end. Because the cylinder moves faster and the sealing requirements of this solution are not high, it is the best solution to use the cylinder as the driving element of the arc-shaped member.

[0096] The stop drive unit 253 and the motor in the drive mechanism are electrically connected to the controller to form a control loop. When the cylinder of the stop drive unit 253 performs the ejection action, the motor stops rotating to prevent the motor from driving the cleaning tool 1 to cause excessive friction with the cushion layer 252. In order to achieve this function, a speed sensor can be set on the motor shaft, and the speed sensor is electrically connected to the controller to form a feedback loop. A preset speed relative to the motor shaft is set. When the speed meets the preset speed, the rotation of the cleaning tool 1 can smoothly centrifuge the cleaning liquid transported by the deflector 241 to the outside of the oil pipe 100, and the flow rate is sufficient. It is best to keep the cleaning liquid filling the inside of the oil pipe 100 during the flow process. With the help of the stop part 25, when the rotation speed of the cleaning tool 1 reaches the speed corresponding to the preset rotation speed of the motor shaft, the motor stops working, and the stop drive unit 253 instantly presses the stop ring 251 against the outside of the cleaning tool 1, stopping the rotation of the cleaning tool 1 and closing the outer end of the oil pipe 100. Because the end of the oil pipe 100 is suddenly closed, the water inside it forms a water hammer effect, vibrating the inner wall of the oil pipe 100. At the same time, because the cleaning tool 1 suddenly stops, the oil pipe 100 itself also vibrates due to inertia. Under the effect of the two internal and external vibration forces, impurities attached to the outer and inner walls are more likely to fall off. Embodiment five:

[0097] On the basis of Example 4, the stop portion 25 further includes a stopper 254. When the cushion layer 252 of the stopper ring 251 abuts against the end of the oil pipe 100 on the cleaning tool 1, one end of the stopper 254 is located on the moving path of the stopper 143. That is to say, as the stopper ring 251 moves toward the cleaning tool 1, the end edge of the stopper 254 first enters the moving path of the stopper 143. When the stopper ring 251 abuts against the end of the oil pipe 100, the end and middle part of the stopper 254 are completely blocked on the moving path of the stopper 143. Therefore, in the process of the stopper ring 251 moving toward the cleaning tool 1, the end edge of the stopper 254 may have collided with the stopper 143, thereby stopping the rotation of the cleaning tool 1. By changing the length of the stopper 254, the time difference from the collision with the stopper 143 to the abutment of the cushion layer 252 and the end of the oil pipe 100 can be changed. In this embodiment, a stopper 254 is provided on each arc-shaped member. In the implementation of this solution, the number of the stoppers 254 may be increased to increase the probability that the stopper 254 collides with the stopper 143 first when stopping.

[0098] The stopper 254 is mainly set up to take into account that if the cleaning tool 1 is simply stopped by the cushion layer 252 against the end of the oil pipe 100 and blocked, the oil pipe 100 and the cushion layer 252 may slip, and the cleaning tool 1 will not stop immediately. Therefore, the stopper 254 is added to reduce the time that the cleaning tool 1 may continue to rotate under the action of inertia due to the slip problem. In order to increase the vibration intensity caused by the sudden blockage of the water flow in the oil pipe 100, thereby improving the cleaning effect of the inside of the oil pipe 100. Embodiment six:

[0099] On the basis of Example 5, the connecting part 13 includes a fixed driven shaft 132, and the driven shaft 132 is fixedly connected to the main fixed ring 111, or fixedly connected to the top plate 112. The connection requirement between the two can be achieved as long as the driven shaft 132 can drive the main fixed part 11 to rotate. The driven shaft 132 is made of a material that can be magnetically adsorbed, or an adsorption part is set at the lower part of the driven shaft 132, and the adsorption part is made of a material that can be magnetically adsorbed.

[0100] The driven shaft 132 can be made into a telescopic structure, which is composed of a sleeved telescopic rod body, the rod body is a prismatic rod body, a hexagonal or octagonal rod, and the adsorption part is the lower rod body of the driven shaft 132. After the cleaning tool 1 is installed in place, the adsorption part of the driven shaft 132 is attached to the upper end of the driving shaft.

[0101] The lower part of the driving shaft of the docking part 22 is linked with the motor shaft of the motor, and an electromagnet is fixedly arranged on the upper part; the driving shaft and the driven shaft 132 are coaxial. The electromagnet is electrically connected to the controller to form a control loop.

[0102] The driven shaft 132 is combined with the electromagnet to form a clutch mechanism. When cleaning, the motor and the electromagnet are both started, and the electromagnet adsorbs the driven shaft 132 to the end of the driving shaft, and the driving shaft drives the driven shaft 132 to rotate. When the speed reaches a preset value, the motor and the electromagnet stop working, and the driven shaft 132 is no longer adsorbed by the electromagnet and can rotate relative to the driving shaft.

[0103] Because this solution has a working link of stopping the cleaning tool 1 instantly, if the cleaning tool 1 and the drive shaft remain connected, even if the cleaning tool 1 is stopped after the motor stops working, the components of the motor itself also need to bear the impact of the sudden stop of rotation, which will affect the service life of the motor. Therefore, a clutch mechanism of a driven shaft 132 and an electromagnet is added. When the motor stops working, the driven shaft 132 and the drive shaft are no longer rigidly connected together. Even if the driven shaft 132 stops rotating first because of the stillness of the cleaning tool 1, the drive shaft can also stop naturally in the subsequent process. Thereby reducing the loss of the motor during the working process. When it is running again, it is only necessary for the electromagnet to adsorb the driven shaft 132 and the drive shaft together again. Embodiment seven:

[0105] S1, arranging the oil pipes 100 to be cleaned into a circumferential radial structure by using a cleaning tool 1;

[0108] S4, draining the cleaning liquid to the middle of the cleaning tool 1, and swinging the cleaning liquid from one end of the oil pipe 100 close to the central axis of the cleaning tool 1 to the other end by means of the centrifugal force generated by the cleaning tool 1;

[0109] S5, during the rotation of the cleaning tool 1, the cleaning tool 1 is made to be stationary within a time period of less than 1 second, and during the stationary period, the end of the oil pipe 100 facing the outside of the cleaning tool 1 is closed;

[0110] S6. After repeating steps S3-S5 for several times, the supply of cleaning liquid is stopped, and the cleaning tool 1 is kept rotating for a certain period of time to throw out the cleaning liquid in the oil pipe 100 to complete the cleaning work.
