Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of train cleaning equipment, in particular to a car coupler protection device in a car washing state and a car washing system. BACKGROUND

[0002] In the daily maintenance of subways and maglev trains, cleaning the front and rear ends of the train is an important work to ensure the appearance of the train and the safety of the train in operation. At present, when cleaning the end face of the train, the grease on the car coupler becomes a thorny problem. As a key component for connecting the train, the car coupler is coated with grease to ensure good connection performance, but during the cleaning process, the grease is easily attached to the end brush bristles. The end brush bristles contaminated with grease will transfer the grease to the end face of the train during subsequent cleaning of the end face of the train, which seriously affects the appearance cleanliness of the end face of the train and reduces the overall image of the train.

[0003] To solve the problem of grease contamination, the existing cleaning method usually chooses to avoid the car coupler area for the end brush bristles. However, although this approach avoids grease contamination, it results in the area near the car coupler being unable to be thoroughly cleaned. The long-term accumulation of dirt in the area near the car coupler not only affects the appearance, but also can have a potential impact on the performance of the car coupler, such as accelerating the corrosion of the car coupler components, reducing the reliability of the car coupler connection, etc. Therefore, it is urgent to develop a device and method that can effectively solve the problem of grease contamination of the end brush bristles and the end face of the train near the car coupler, while ensuring the cleaning effect of the area near the car coupler.

[0049] Referring to Figure 1 and Figure 2 , the embodiment of the present application proposes a car hook protection device 1000 in a car washing state, the car hook protection device 1000 comprises a protective cover 100 and a displacement driving mechanism 200, the protective cover 100 has a working position and a non-working position, the protective cover 100 can protect the car hook 2100 when in the working position; the displacement driving mechanism 200 is drivingly connected to the protective cover 100, and drives the protective cover 100 to switch between the working position and the non-working position.

[0050] According to the car hook protection device 1000 in the car washing state of the embodiment of the present application, in the car washing scene, the protection cover 100 will be in the working position, at which time it will cover the car hook 2100. The car hook 2100 is usually coated with grease, and during the car washing process, if the grease on the car hook 2100 adheres to the bristles of the end brush of the car washing equipment, the grease may be transferred to the end surface of the train 2000 along with the bristles of the end brush, causing contamination of the end surface of the train 2000. By covering the car hook 2100 with the protection cover 100, this situation can be effectively prevented. At the same time, because the car hook 2100 is protected, the area near the car hook 2100 is not disturbed during car washing and can be thoroughly cleaned. In this way, the overall effect of cleaning the train 2000 is improved, not only ensuring the neatness of the appearance of the train 2000, but also playing a positive role in the safe operation of the train 2000.

[0051] When the train 2000 is not performing a car washing operation, the displacement driving mechanism 200 will drive the protection cover 100 to the non-working position. This is because if the protection cover 100 is still in the working position when the train 2000 is running, it may interfere with other equipment around the running track of the train 2000 or some parts of the train 2000 itself, thereby causing potential risks and affecting the normal operation of the train 2000. Switching the protection cover 100 to the non-working position can avoid these risks and ensure smooth operation of the train 2000.

[0052] Referring to Figure 1 and Figure 2 In some embodiments, the protection cover 100 includes a bottom plate 140, a first protection cover 110, and a second protection cover 120, one end of the first protection cover 110 being rotatably connected to the bottom plate 140, the other end of the first protection cover 110 and one end of the second protection cover 120 being rotatably connected; wherein the protection cover 100 has an unfolded state and a folded state; in the unfolded state, the first protection cover 110 and the second protection cover 120 can be covered outside the car hook 2100; in the folded state, the first protection cover 110 and the second protection cover 120 are folded; a folding driving member 130, the folding driving member 130 being drivingly connected to the second protection cover 120, the folding driving member 130 driving the second protection cover 120 to rotate relative to the first protection cover 110, so that the protection cover 100 is switched between the unfolded state and the folded state.

[0053] With the above arrangement, one end of the first protective cover 110 is rotationally connected with the bottom plate 140, and the first protective cover 110 can rotate about the connection point. The other end of the first protective cover 110 is rotationally connected with one end of the second protective cover 120, so that the first protective cover 110 and the second protective cover 120 can also rotate relative to each other. The protective cover 100 has an unfolded state and a folded state. In the unfolded state, the first protective cover 110 and the second protective cover 120 cooperate with each other and can be arranged outside the coupler 2100, thereby protecting the coupler 2100, preventing the coupler 2100 from being contaminated by the brush bristles during washing, and preventing the bristles contaminated by oil from polluting the front and rear end faces of the train 2000 during cleaning. At the same time, it can also ensure the cleaning effect of the area near the coupler 2100. In the folded state, the first protective cover 110 and the second protective cover 120 are folded, occupying less space, facilitating storage and avoiding interference with the train 2000 operation when not in use.

[0054] The folding driving member 130 is used to switch the unfolded state and the folded state of the protective cover 100. The folding driving member 130 is drivingly connected with the second protective cover 120, and is used to drive the second protective cover 120 to rotate relative to the first protective cover 110. When the folding driving member 130 works, it drives the second protective cover 120 to rotate, so that the protective cover 100 changes from the unfolded state to the folded state, or from the folded state to the unfolded state. In some embodiments, the folding driving member 130 includes a telescopic support rod, one end of the telescopic support rod is rotationally connected with one end of the second protective cover 120 away from the first protective cover 110, and the other end is rotationally connected with the bottom plate 140. The telescopic support rod is used to drive the second protective cover 120 to rotate by telescoping, thereby switching the state of the protective cover 100.

[0055] Referring to Figure 3 In some embodiments, the first protective cover 110 includes a first protective body 111 and first protective side plates 112 arranged on both sides of the first protective body 111. The first protective body 111 directly protects the coupler 2100, and its shape, size and material are designed to effectively protect the coupler 2100. For example, it is necessary to ensure that it can cover the key parts of the coupler 2100 and block the contact between the end brush bristles during washing and the oil of the coupler 2100. The first protective side plates 112 are arranged on both sides of the first protective body 111. On the one hand, they can further block the end brush bristles from approaching the coupler 2100 from the side, thereby enhancing the protection effect of the protective cover 100 on the coupler 2100 and reducing the risk of the coupler 2100 oil contaminating the end brush bristles. On the other hand, the side plates can prevent water, cleaning liquid and the like from splashing onto the coupler 2100 from the side during washing, thereby avoiding corrosion or other damage to the coupler 2100 and ensuring the normal operation and service life of the coupler 2100.

[0056] Referring to Figure 3In some embodiments, the second protective cover 120 comprises a second protective body 121 and second protective side plates 122 arranged on both sides of the second protective body 121. The second protective side plates 122 improve the protection effect from the side.

[0057] In some embodiments, when the protective cover 100 is in the unfolded state, the first protective cover 110 is horizontally arranged above the vehicle coupler 2100, and the second protective cover 120 is obliquely arranged in front of the vehicle coupler 2100.

[0058] It can be understood that the first protective cover 110 and the second protective cover 120 can be made of high-strength and corrosion-resistant materials and closely fit the shape of the vehicle coupler 2100.

[0059] Referring to Figure 1 and Figure 2 In some embodiments, the folding driving member 130 comprises a telescopic support rod, one end of which is rotatably connected to the end of the second protective cover 120 away from the first protective cover 110, and the other end is rotatably connected to the bottom plate 140.

[0060] Through the above arrangement, the telescopic support rod can exert a driving force on the second protective cover 120 to promote the rotation of the second protective cover 120. The other end is rotatably connected to the bottom plate 140, which provides a stable support point and a movable base for the telescopic support rod, ensuring the stability and reliability of the entire driving structure. When the telescopic support rod is extended or shortened, since its two ends are rotatably connected to the second protective cover 120 and the bottom plate 140 respectively, it will drive the second protective cover 120 to rotate relative to the first protective cover 110 around the rotation connection point with the first protective cover 110. When the telescopic support rod is extended, it will push the second protective cover 120 to rotate, so that the protective cover 100 gradually changes from the folded state to the unfolded state, so that it can be arranged outside the vehicle coupler 2100 to protect the vehicle coupler 2100 when washing the car. When the telescopic support rod is shortened, the second protective cover 120 rotates in the opposite direction, and the protective cover 100 changes from the unfolded state to the folded state, facilitating storage or avoiding affecting the normal operation of the train 2000.

[0061] It can be understood that in some embodiments, the folding driving member 130 can also have a variety of different mechanical mechanisms, such as a crank and connecting rod mechanism or a lead screw and nut mechanism. The crank and connecting rod mechanism includes a crank, a connecting rod, and a slider. The crank is driven by the motor to make a circular motion, which is converted into a linear motion of the slider through the connecting rod. The slider is connected to the second protective cover 120, thereby driving the second protective cover 120 to rotate. The lead screw and nut mechanism includes a lead screw and a nut. The motor drives the lead screw to rotate, and the nut moves linearly on the lead screw. The nut is connected to the second protective cover 120, thereby driving the second protective cover 120 to rotate.

[0062] Referring to Figure 1 andFigure 2 In some embodiments, the displacement driving mechanism 200 comprises a pneumatic cylinder, the output end of the pneumatic cylinder is connected with the bottom plate 140, and the pneumatic cylinder drives the protective cover 100 to switch between the working position and the non-working position. Through the above arrangement, when it is needed to protect the coupler 2100 for car washing operation, compressed air is supplied into the pneumatic cylinder, and the output end of the pneumatic cylinder is extended. Since the output end is connected with the bottom plate 140, in the process of extension, the bottom plate 140 and the entire protective cover 100 connected therewith are pushed to move towards the coupler 2100 until the protective cover 100 reaches the working position, at which time the protective cover 100 is unfolded and covers the coupler 2100, so as to avoid the grease of the coupler 2100 from staining the brush bristles of the end brush and to ensure the cleaning effect. When the car washing is completed and the protective cover 100 is not needed to work, the compressed air in the pneumatic cylinder is discharged, the output end of the pneumatic cylinder is retracted, and the protective cover 100 is driven to return from the working position to the non-working position, such as being stored in the pit 300, so as to prevent the protective cover 100 from causing interference when the train 2000 is running and to ensure the smooth running of the train 2000.

[0063] It can be understood that in some embodiments, the displacement driving mechanism 200 can also have a plurality of other mechanical mechanisms, such as an electric push rod, a hydraulic cylinder or a chain transmission mechanism, which can drive the protective cover 100 to switch between the working position and the non-working position. The electric push rod mainly comprises a driving motor, a speed reduction gear, a screw rod, a nut, a guide sleeve, a push rod and a sliding seat. The motor drives the speed reduction gear to rotate, the speed reduction gear drives the screw rod to rotate, the nut on the screw rod moves linearly along the screw rod, and in turn the push rod connected with the nut moves linearly, so as to realize the switching of the position of the protective cover 100 through the connection of the push rod with the bottom plate 140 of the protective cover 100. The hydraulic cylinder is composed of a cylinder barrel, a piston, a piston rod and a sealing element. The hydraulic oil is delivered to different chambers of the oil cylinder by a hydraulic pump, the piston is pushed to move linearly in the cylinder barrel by the pressure of the hydraulic oil, the piston rod is connected with the piston and extends out of the cylinder barrel, thereby driving the bottom plate 140 of the protective cover 100 connected with the piston rod to move and realizing the switching of the position of the protective cover 100. The chain transmission mechanism mainly comprises a motor, a chain wheel and a chain. The motor drives the chain wheel to rotate, the chain wheel drives the chain to move in a cycle, the chain is connected with the bottom plate 140 of the protective cover 100, and the movement of the chain drives the protective cover 100 to move between the working position and the non-working position.

[0064] Referring to Figure 1 and Figure 2 In some embodiments, a pit 300 is dug in the middle ground of the track corresponding to the coupler 2100, and the protective cover 100 is stored in the pit 300 when the protective cover 100 is in the folded state. The pit 300 is used to store the protective cover 100 in the folded state, so as to optimize the space layout of the train 2000 running and car washing operation and to improve the safety and functionality of the overall system.

[0065] Specifically, a pit 300 is dug in the middle of the track corresponding to the coupler 2100 to provide a specific accommodation space for the protective cover 100. When the protective cover 100 is in the folded state, it is accommodated in the pit 300, effectively utilizing the space below the middle of the track, avoiding the occupation of additional space above the middle of the track by the protective cover 100. This is crucial for the space layout of the train 2000 operation area, which can prevent the protective cover 100 from interfering with the normal running of the train 2000 in the non-working state, ensuring smooth running of the train 2000. For example, when the train 2000 runs on the track, there is no risk of collision due to the protruding protective cover 100 in the middle of the track.

[0066] In the car washing operation scenario, when washing the car, the protective cover 100 is unfolded to protect the coupler 2100, and after the car washing is completed, the protective cover 100 is folded and accommodated in the pit 300, which does not affect the normal operation of the car washing equipment. When the car washing equipment is performing cleaning operations on the train 2000, there is no cleaning blind area or collision problem due to the presence of the protective cover 100, ensuring efficient and safe car washing operations.

[0067] Referring to Figure 4 In some embodiments, the coupler protection device 1000 further comprises a trajectory guiding mechanism 500 connected with the protective cover 100, which guides the trajectory of the protective cover 100 during switching between the working position and the non-working position.

[0068] Through the above arrangement, the trajectory guiding mechanism 500 in the coupler protection device 1000 ensures that the protective cover 100 can move along a specific path when switching between the working position and the non-working position. In actual operation, if the movement trajectory of the protective cover 100 is not controlled, problems such as deviation, jamming, and even collision may occur, which not only affects the normal use of the protective cover 100, but also may cause damage to the coupler 2100, the end face of the train 2000, or other equipment. Therefore, the trajectory guiding mechanism 500 is crucial for ensuring the reliable operation of the protective cover 100. The trajectory guiding mechanism 500 is connected with the protective cover 100, and this connection enables the guiding mechanism to effectively control the movement of the protective cover 100. When the protective cover 100 switches positions, the two work together, and the guiding mechanism provides guiding force to the protective cover 100 to ensure the accuracy of its movement trajectory.

[0069] During switching, the trajectory guiding mechanism 500 plays a guiding role. When the protective cover 100 moves from the working position to the non-working position, or from the non-working position to the working position, the trajectory guiding mechanism 500 plans and limits the movement route.

[0070] In some embodiments, the trajectory guiding mechanism 500 comprises a guiding slide 510 and a guiding roller 520. The guiding slide 510 is arranged along a straight line and points from the working position to the non-working position. The guiding roller 520 is capable of sliding in the guiding slide 510 and is mounted on the protective cover 100. Through the above arrangement, the guiding slide 510 defines the path of the movement of the protective cover 100. The guiding roller 520 is mounted on the protective cover 100 and forms an integral whole with the protective cover 100 and moves together with the protective cover 100. The guiding roller 520 is mounted on the protective cover 100 and is capable of sliding in the guiding slide 510. When the protective cover 100 needs to switch between the working position and the non-working position, the displacement driving mechanism 200 such as a pneumatic cylinder drives the movement of the protective cover 100, and the guiding roller 520 mounted on the protective cover 100 rolls and slides in the guiding slide 510 along the direction of the slide. The cooperation between the guiding roller 520 and the guiding slide 510, on the one hand, limits the movement direction of the protective cover 100, so that it can only move along the straight line trajectory defined by the guiding slide 510; on the other hand, the rolling of the roller can reduce the friction when the protective cover 100 moves, so that the movement of the protective cover 100 is smoother, the energy consumption is reduced, and the wear of the protective cover 100 and the guiding slide 510 is reduced, the service life and reliability of the whole device are improved.

[0071] At least one embodiment of the present application provides a car washing system, which comprises a car washing mechanism and the car hook protection device 1000 in any of the above embodiments in the car washing state. The car washing system integrates the car washing mechanism and the car hook protection device 1000, aiming to improve the overall effect and safety of the train 2000 car washing. The car washing mechanism is responsible for cleaning the end face of the train 2000, removing dirt on the end face of the train 2000 through various cleaning methods, and ensuring the neat appearance of the train 2000. The car hook protection device 1000 is specially designed to solve the problem of grease pollution of the car hook 2100 during car washing, which can avoid the contamination of the end brush bristles by the grease of the car hook 2100 and prevent the grease from polluting the front and rear end faces of the train 2000.

[0072] The car hook protection device 1000 protects the car hook 2100 during car washing, so that the area near the car hook 2100 can be thoroughly cleaned, making up for the possible cleaning dead angle problem of conventional car washing. At the same time, it avoids the pollution of the end brush bristles of the car washing mechanism and the front and rear end faces of the train 2000 by the grease of the car hook 2100, ensuring the normal operation of the car washing mechanism and the appearance quality of the train 2000. When not washing the car, the protective cover 100 of the car hook protection device 1000 can be switched to the non-working position, without affecting the normal operation of the train 2000. This combined design improves the overall effect of train 2000 cleaning, guarantees the neat appearance and safe operation of the train 2000. Not only improves the work efficiency of the car washing system, but also reduces the maintenance cost and safety risk caused by the grease pollution of the car hook 2100.

[0073] Referring to Figure 1 In some embodiments, the car washing system further comprises a detector 600 arranged on the protective cover 100 for determining whether the protective cover 100 reaches the working position, and a controller in communication with the car washing mechanism for receiving the car washing signal and starting the car washing mechanism according to the car washing signal.

[0074] Through the above arrangement, the detector 600 and the controller in the car washing system cooperate with each other to realize automatic car washing operation and ensure the safety and efficiency of the car washing process.

[0075] Specifically, the detector 600 is installed on the protective cover 100 to monitor the position state of the protective cover 100 in real time. During the preparation stage of the car washing system, the protective cover 100 moves to the working position under the action of the displacement driving mechanism 200. During this process, the detector 600 continuously detects the position information of the protective cover 100. When the protective cover 100 accurately reaches the working position capable of effectively protecting the car hook 2100, the detector 600 quickly makes a judgment and triggers the car washing signal. The issuance of this signal is a key precondition for the start of the entire car washing process, which ensures that the car washing operation will only be started when the protective cover 100 is completely in place and the car hook 2100 is properly protected, avoiding problems such as grease pollution of the train end surface caused by the car hook 2100 due to the protective cover 100 not being in place.

[0076] The controller is in communication with the car washing mechanism. After the controller receives the car washing signal from the detector 600, it will analyze and process according to the preset program logic. After confirming that the signal is correct, the controller sends a start instruction to the car washing mechanism. In this way, the controller converts the detection result of the detector 600 into actual car washing action, realizes the automatic control of the car washing system, and makes each component work in an orderly and coordinated manner, improving the overall operation efficiency and reliability of the car washing system.

[0077] The cooperation between the detector 600 and the controller greatly improves the intelligence and safety of the car washing system. On the one hand, it avoids the mistakes that may occur in manual judgment of the position of the protective cover 100, ensures that the protective cover 100 can be accurately positioned before each car washing operation, and reduces the risk of grease pollution of the car hook 2100; on the other hand, the automatic start process improves the car washing efficiency, eliminates the need for manual start of the car washing mechanism, saves labor costs, and makes the car washing process more standardized and standardized, ensuring that the train 2000 car washing work can be carried out stably and efficiently.

[0078] In some embodiments, the sensor for determining whether the protective cover 100 reaches the working position can have various types, such as mechanical limit switch, proximity switch, photoelectric sensor or magnetic sensor. Among them, the mechanical limit switch is a common position detection device. When the protective cover 100 moves to the working position, it will touch the operating head of the limit switch, and the action of the operating head will trigger the closing or opening of the contact system, thereby generating an electrical signal, which can be used as a car washing signal received by the controller. It has simple structure, low cost and high reliability, and can work stably in harsh environment, and has certain resistance to dust, oil and other factors.

[0079] The proximity switch is a non-contact detection device that uses electromagnetic induction, capacitance induction and other principles to detect the approach of objects. When the protective cover 100 approaches the working position, the proximity switch can detect the change of magnetic field or capacitance caused by the metal parts or special material parts of the protective cover 100, and convert it into an electrical signal output. It does not need to be in direct contact with the protective cover 100, avoiding mechanical wear and tear, with long service life, fast response speed and high detection accuracy and reliability, and can be used in humid and dusty environments.

[0080] The photoelectric sensor determines the position of the object by emitting light and detecting the reflection or blocking of the light. There are two common types: reflective and reflective. The reflective photoelectric sensor is composed of a transmitter and a receiver. When the protective cover 100 moves to the working position, it will block the light emitted by the transmitter, and the receiver will not receive the light signal, thereby outputting the corresponding electrical signal; the reflective photoelectric sensor is that the transmitter and receiver are on the same side. When the protective cover 100 approaches the working position, the light is reflected back by the protective cover 100 and received by the receiver, thereby triggering the signal output. It has high detection accuracy, fast response speed and can realize non-contact detection, with less restriction on the material of the detected object. Moreover, the detection distance can be adjusted according to actual needs, suitable for different application scenarios.

[0081] The magnetic sensor determines the position of the object by detecting the change of magnetic field. A magnet is installed near the protective cover 100 or the working position. When the protective cover 100 moves to the working position, the magnetic sensor can detect the change of magnetic field and convert it into an electrical signal. It has high sensitivity and reliability, and can work in harsh environmental conditions, and is not sensitive to dust, humidity and other factors. Moreover, the non-contact detection method avoids mechanical wear and tear, with long service life.

[0082] According to the car washing system provided in the embodiment of the present application, the car hook 2100 is covered by the protective cover 100, so that the grease of the car hook 2100 is effectively prevented from adhering to the brush hair of the end brush, thereby preventing the grease from polluting the end face of the train, ensuring that the area near the car hook 2100 can be thoroughly cleaned, improving the overall effect of the train 2000 cleaning, and guaranteeing the appearance neatness and operation safety of the train 2000.
