Description

Technical Field

[0001] The present application relates to the technical field of water heaters, and in particular to providing a debugging device for a train water heater control box. Background Art

[0002] Providing hot water to train passengers and crew members is an indispensable part of train operations. The water heaters on railway trains are currently generally electric water heaters, and the control box is the core component of the electric water heater, which controls the water inlet, heating and other functions of the electric water heater.

[0003] A Chinese patent with publication number CN212723747U discloses a debugging device suitable for a control box of an electric water heater for trains, comprising a cabinet, a debugging platform and a control box, wherein the control box is arranged on the debugging platform, and a plurality of electric water tanks, solenoid valves and liquid level gauges for debugging are arranged in the cabinet, a first interface and a second interface are arranged on the cabinet, the first interface is connected to the electric water tank, and the second interface is connected to the outlet end of the solenoid valve, a main water inlet pipe is also arranged in the cabinet, the water inlet of the main water inlet pipe is arranged on the cabinet, and the main water inlet pipe is connected to the inlet end of the solenoid valve, the debugging device integrates the water tank, water pipe, wire and other equipment required for debugging into a debugging cabinet with an integrated structure, and reserves an interface for connecting to the control box on the cabinet, and the debugging can be quickly performed by connecting the interface on the debugging device, with a higher degree of intensiveness, saving time and effort in the debugging process, and making the debugging site neater and more standardized.

[0004] However, when the train is running for a long time and a long distance, the electric water heater may malfunction. At this time, it is necessary to use a debugging device to debug and test the control box. However, there are many uncertain factors in the process of train running. For example, when the train is running on an uneven track, or when the train suddenly accelerates or decelerates, the objects in the train car will shake to varying degrees. When the debugging device shakes, the stability of the control box on the debugging device will be reduced. At this time, the control box moves left and right on the debugging platform. In severe cases, the control box may directly fall off the debugging platform and fall to the ground, which is obviously insufficient. Utility Model Content

[0005] In order to improve the stability of the control box on the debugging device, the present application provides a debugging device for the train water heater control box.

[0006] The present application provides a train water heater control box debugging device that adopts the following technical solution:

[0007] A debugging device for a train water heater control box comprises a cabinet and a debugging platform, wherein the debugging platform is arranged above the cabinet, four rollers are arranged under the cabinet, a mounting groove is opened on the debugging platform, a control box is slidably connected in the mounting groove, a clamping assembly is arranged on the debugging platform, the clamping assembly comprises a first screw and a second screw rotatably connected to the debugging platform, the first screw and the second screw are arranged opposite to each other, a first clamping plate and a second clamping plate are slidably connected in the mounting groove, one end of the first clamping plate is threadedly connected to the first screw, and the other end is slidably connected to the second screw, one end of the second clamping plate is threadedly connected to the second screw, and the other end is slidably connected to the first screw, and the opposing surfaces of the first clamping plate and the second clamping plate are both in close contact with the outer surface of the control box.

[0008] By adopting the above technical solution, when debugging is required, the control box to be debugged is placed in the installation groove, and then the first screw is rotated first, and the first screw drives the first clamping plate to approach the control box. When the first clamping plate is in close contact with the outer wall of the control box, the first screw is stopped and the second screw is rotated, and the second screw drives the second clamping plate to approach the control box. When the second clamping plate is also in close contact with the outer wall of the control box, the control box is fixed in the installation groove by the clamping assembly. When the train shakes, the control box cannot be displaced due to the restrictions of the clamping assembly and the installation groove, and the stability of the control box on the debugging device is improved.

[0009] Optionally, grooves are provided at two opposite ends of the bottom surface of the cabinet, a rotating shaft is rotatably connected in each of the grooves, and tripods are provided at both ends of the rotating shaft extending out of the grooves. The tripods are rotatably connected to the outer wall of the cabinet, and the four rollers are respectively arranged at the four ends of the tripods away from the cabinet.

[0010] By adopting the above technical solution, when the cabinet needs to be moved, the rotating shaft is rotated in the forward direction, and the rotating shaft drives the tripod to rotate. When the tripod is rotated to a vertical position, the roller is in contact with the ground. At this time, the maintenance personnel can easily move the cabinet to the maintenance position. When it is moved to the debugging position, the rotating shaft is rotated in the opposite direction, and the rotating shaft drives the tripod to rotate. The tripod drives the casters to gradually move away from the ground. When the tripod is rotated to a horizontal position, the roller is separated from the ground and is stored on the outer wall of the cabinet, thereby reducing the possibility of the roller driving the cabinet to move as a whole when the car shakes. The stability of the cabinet on the car floor is improved, thereby further improving the stability of the control box on the debugging device.

[0011] Optionally, each of the tripods is provided with a horizontal fixing hole and a vertical fixing hole, and both the horizontal fixing hole and the vertical fixing hole are threaded holes. When the tripod is in a horizontal or vertical state, the tripod is fixed to the cabinet by bolts.

[0012] By adopting the above technical solution, when the cabinet needs to be moved, the tripod is rotated to a vertical state through the rotating shaft, and then the tripod is fixed in the vertical state through the vertical fixing holes and bolts, thereby improving the stability of the cabinet during the movement. When debugging, the tripod is rotated to a horizontal state through the rotating shaft, and the tripod is fixed in the horizontal state through the horizontal fixing holes and bolts, reducing the possibility of the roller contacting the ground again during the debugging process, thereby improving the overall stability of the debugging device.

[0013] Optionally, suction cups corresponding to the rollers are provided on the bottom surface of the cabinet, and the suction surfaces of the suction cups face the floor of the carriage. When the tripod is in a horizontal state, the suction cups are adsorbed on the floor of the carriage.

[0014] By adopting the above technical solution, when the tripod is in a horizontal state, the suction cup generates an adsorption force on the floor of the carriage, thereby increasing the friction between the debugging device and the floor of the carriage, further reducing the possibility of the cabinet sliding when the carriage shakes, and improving the overall stability of the debugging device.

[0015] Optionally, each of the suction cups is provided with an air cylinder, which is arranged on the bottom surface of the cabinet. An air cavity is defined in the air cylinder, a piston block is slidably connected in the air cavity, an outer surface of the piston block is tightly fitted with an inner wall of the air cavity, an adsorption hole connected to the air cavity is defined on the suction cup, and a driving component for driving the piston block to reciprocate along the air cavity is provided on the cabinet.

[0016] By adopting the above technical solution, when it is necessary to fix the cabinet body by means of a suction cup, the driving assembly drives the piston block to move in a direction away from the suction cup, and the air in the air cavity and the adsorption hole is completely extracted by the piston block. Under the action of atmospheric pressure, the suction cup is fastened to the floor of the car. When it is necessary to move the cabinet body, the driving assembly drives the piston block to move in a direction close to the suction cup, so that gas is re-introduced into the air cylinder and the adsorption hole, thereby reducing the pressure difference between the inside and outside of the suction cup, and reducing the adsorption force of the suction cup on the floor of the car, making it convenient for the debugging personnel to easily move the cabinet body later.

[0017] Optionally, the drive assembly includes a worm segment coaxially connected to the rotating shaft, a worm wheel meshingly arranged on the worm segment, the worm wheel rotatably connected to the inside of the groove, a lead screw rotatably connected inside the air cylinder, the worm wheel fixedly connected to one end of the lead screw extending out of the air cylinder, the piston block threadedly connected to the lead screw, and the cross-sections of the piston block and the air cavity are both square.

[0018] By adopting the above technical scheme, in the process of the rotating shaft driving the tripod to rotate from a vertical state to a horizontal state, the rotating shaft simultaneously drives the worm section to rotate, and the worm section drives the worm wheel to rotate, thereby realizing the rotation of the screw, and the screw drives the piston block to move toward the direction of the suction cup. At this time, the suction force of the suction cup on the floor of the car gradually increases. When the rotating shaft drives the tripod to rotate from a horizontal state to a vertical state, the rotating shaft drives the piston block to move away from the suction cup through the worm section and the worm wheel, and the suction force of the suction cup on the floor of the car is reduced, which is convenient for subsequent personnel to move the cabinet. The setting of the drive component realizes the simultaneous extension and retraction of the tripod and the adjustment of the suction force of the suction cup, simplifies the operating steps of the debugging personnel, and improves the convenience and efficiency of work.

[0019] Optionally, a protective plate is provided on both the first clamping plate and the second clamping plate, the length direction of the protective plate is perpendicular to the length direction of the mounting groove, and the protective plate is in close contact with the outer side wall of the control box.

[0020] By adopting the above technical solution, when the first clamping plate and the second clamping plate clamp the control box, the protective plate is in close contact with the outer surface of the control box, thereby further improving the stability of the control box on the protective device.

[0021] Optionally, the surfaces opposite to each other of the first clamping plate and the second clamping plate are provided with rubber pads, and the rubber pads are in close contact with the outer surface of the control box.

[0022] By adopting the above technical solution, the rubber pad can reduce the clamping force on the control box when it is clamped, reducing the possibility of the control box being deformed by clamping. At the same time, the rubber pad, as an elastic material, can fill the gap between the outer wall of the control box and the first clamping plate and the second clamping plate, thereby further reducing the possibility of the control box shaking on the debugging platform and improving the stability of the control box on the debugging device.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The present application provides a clamping assembly, a mounting groove and a protective plate to fix the control box in all directions, thereby improving the stability of the control box during the debugging process and preventing the control box from moving left and right on the debugging platform. In serious cases, the control box directly falls off the debugging platform and onto the ground, thereby improving the safety of the control box during the debugging process;

[0025] 2. This application sets a rotating shaft, a tripod, a suction cup, an air cylinder and a driving assembly. The rotating shaft and the driving assembly are set to achieve the extension and retraction of the tripod while adjusting the suction force of the suction cup. This integrated operation method greatly simplifies the operation steps of the commissioning personnel and improves the convenience and efficiency of the work. At the same time, it also ensures that the commissioning device can maintain excellent stability in various environments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] An embodiment of the present application discloses a debugging device for a train water heater control box.

[0033] Reference Figure 1 A train water heater control box debugging device comprises a cabinet 1 and a debugging platform 2. The debugging platform 2 is fixedly mounted on the top surface of the cabinet 1. A mounting groove 21 is provided on the debugging platform 2. The length direction of the mounting groove 21 is parallel to the length direction of the debugging platform 2. A control box 3 is placed in the mounting groove 21. The control box 3 is slidably connected in the mounting groove 21. A clamping assembly 4 for clamping the control box 3 is provided on the debugging platform 2. Four rollers 5 are arranged under the bottom surface of the cabinet 1. The four rollers 5 are respectively arranged at the four corners of the cabinet 1.

[0034] When debugging is required, the debugging personnel pushes the roller 5 to move the cabinet 1 to the debugging position, then places the control box 3 in the installation groove 21, and secures the control box 3 in the installation groove 21 through the clamping assembly 4, then connects the control box 3 with the pipeline of the water heater in the cabinet 1, and starts the debugging operation.

[0035] Reference Figure 1 and Figure 2 The clamping assembly 4 includes a first screw 41 and a second screw 42 rotatably connected to the debugging platform 2. The length directions of the first screw 41 and the second screw 42 are parallel to the mounting groove 21. The first screw 41 and the second screw 42 are respectively arranged at opposite ends of the debugging platform 2. A first clamping plate 43 and a second clamping plate 44 are slidably connected in the mounting groove 21. One end of the first clamping plate 43 is threadedly connected to the first screw 41, and the other end is slidably connected to the second screw 42. One end of the second clamping plate 44 is threadedly connected to the second screw 42, and the other end is slidably connected to the second screw 42. Connected to the first screw rod 41, rubber pads 6 are installed on the opposite end surfaces of the first clamping plate 43 and the second clamping plate 44, and the two rubber pads 6 are tightly attached to the outer surface of the control box 3. The first clamping plate 43 and the second clamping plate 44 are fixedly connected to the end surfaces away from the first screw rod 41 with protective plates 7, and the length direction of the protective plate 7 is perpendicular to the length direction of the mounting groove 21. The protective plate 7 is tightly attached to the outer wall of the control box 3. The same end of the first screw rod 41 and the second screw rod 42 is fixedly connected with a hand wheel (not shown in the figure), and the hand wheel is rotatably connected to the outer wall of the debugging platform 2.

[0036] When clamping is required, the debugging personnel rotate the first screw 41 through the hand wheel, and the first screw 41 drives the first clamping plate 43 to approach the control box 3. When the rubber pad 6 on the first clamping plate 43 is in close contact with the outer wall of the control box 3, the first screw 41 is stopped and the second screw 42 is rotated. The second screw 42 drives the second clamping plate 44 to approach the control box 3. When the rubber pad 6 on the second clamping plate 44 is also in close contact with the outer wall of the control box 3, the control box 3 is fixed between the first clamping plate 43, the second clamping plate 44 and the protective plate 7. When the train shakes, the control box 3 cannot be displaced due to the restrictions of the clamping assembly 4 and the mounting groove 21, and the stability of the control box 3 on the debugging device is improved.

[0037] Reference Figure 2 and Figure 3 Two grooves 8 are provided on the ground of the cabinet 1 close to the floor of the carriage, and the two grooves 8 are respectively arranged at both ends of the cabinet 1. A rotating shaft 9 is rotatably connected in each groove 8. Both ends of the rotating shaft 9 extending out of the groove 8 are fixedly connected with a tripod 10. The tripod 10 rotates on the outer wall of the cabinet 1, and the roller 5 is fixedly connected to the end of the tripod 10 away from the cabinet 1.

[0038] When it is necessary to move the cabinet 1, the debugging personnel rotate the rotating shaft 9 in the forward direction, and the rotating shaft 9 drives the tripod 10 to rotate. When the tripod 10 rotates to a vertical position, the roller 5 contacts the ground. At this time, the maintenance personnel can easily move the cabinet 1 to the maintenance position. After moving to the debugging position, the debugging personnel rotate the rotating shaft 9 in the opposite direction, and the rotating shaft 9 drives the tripod 10 to rotate. The tripod 10 drives the caster to gradually move away from the ground. When the tripod 10 rotates to a horizontal position, the roller 5 is separated from the ground and is stored on the outer wall of the cabinet 1, thereby reducing the possibility that the roller 5 drives the cabinet 1 to move as a whole when the car shakes. The stability of the cabinet 1 on the car floor is improved, thereby further improving the stability of the control box 3 on the debugging device.

[0039] Reference Figure 2 and Figure 3 In order to further improve the stability of the tripod 10 in the horizontal or vertical state, each tripod 10 is provided with a horizontal fixing hole 101 and a vertical fixing hole 102, both of which are threaded holes. When the tripod 10 is rotated to the horizontal or vertical state by the rotating shaft 9, the maintenance personnel fix the tripod 10 to the outer wall of the cabinet 1 by the bolts 11, thereby ensuring that no accidental movement or shaking occurs during use.

[0040] Reference Figure 3 and Figure 4 Suction cups 12 corresponding to the rollers 5 are arranged on the bottom surface of the cabinet 1, and four suction cups 12 are respectively arranged at the four corners of the cabinet 1, and the adsorption surfaces of the suction cups 12 are arranged toward the bottom surface of the carriage. When the cabinet 1 is moved to the debugging position, the suction cups 12 are tightly adsorbed on the carriage floor. The adsorption force of the suction cups 12 on the carriage floor increases the friction between the cabinet 1 and the carriage floor, thereby further increasing the stability of the debugging device. The setting of the suction cups 12 enables the debugging device to remain stable in various carriage environments, providing a strong guarantee for the debugging work of the control box 3.

[0041] Reference Figure 3 and Figure 4 Each suction cup 12 is fixedly connected to an air cylinder 13, and one end of the air cylinder 13 away from the suction cup 12 is fixedly connected to the bottom surface of the cabinet 1, and an air cavity 131 is provided inside the air cylinder 13, and the air cavity 131 extends along the length direction of the air cylinder 13, and a piston block 132 is slidably connected inside the air cavity 131, and the outer surface of the piston block 132 is tightly fitted with the inner surface of the air cavity 131 to ensure good sealing inside the air cavity 131, and a suction hole 121 connected to the air cavity 131 is provided on the suction cup 12, and a driving component 14 for driving the piston block 132 to reciprocate along the length direction of the air cylinder 13 is provided on the cabinet 1.

[0042] Reference Figure 3 and Figure 4The driving assembly 14 includes a worm section 141 coaxially connected to the rotating shaft 9, a worm wheel 142 is meshed on the worm section 141, the worm wheel 142 is rotatably connected in the groove 8, a screw rod 143 is rotatably connected inside the air cylinder 13, one end of the screw rod 143 away from the suction cup 12 extends into the accommodating groove and is fixedly connected to the worm wheel 142, a piston block 132 is threadedly connected to the screw rod 143, and the cross-sections of the piston block 132 and the air cavity 131 are both square to ensure that the piston block 132 can move smoothly inside the air cavity 131.

[0043] In the process of driving the casters to be stored, the rotating shaft 9 drives the tripod 10 to rotate from a vertical state to a horizontal state, and at the same time the worm segment 141 rotates, and the worm segment 141 drives the worm wheel 142 to rotate, thereby realizing the rotation of the screw rod 143, and the screw rod 143 drives the piston block 132 to move toward the suction cup 12, and the air in the air cavity 131 and the adsorption hole 121 will be gradually drawn out by the piston block 132. Under the action of atmospheric pressure, the adsorption force of the suction cup 12 on the car floor gradually increases, and finally the suction cup 12 will be tightly fixed on the car floor, thereby significantly enhancing the overall stability of the debugging device.

[0044] On the contrary, when the casters are needed, the rotating shaft 9 drives the tripod 10 to rotate from the horizontal to the vertical state. In this process, the rotating shaft 9 will drive the piston block 132 to move away from the suction cup 12 through the worm section 141 and the worm wheel 142. As the piston block 132 moves, gas will be re-introduced into the air cylinder 13 and the adsorption hole 121, thereby reducing the pressure difference between the inside and outside of the suction cup 12. The adsorption force of the suction cup 12 on the floor of the carriage will also gradually decrease, allowing the debugging personnel to easily move the cabinet 1 to the debugging position. The setting of the rotating shaft 9 and the driving component 14 can achieve the extension and retraction of the tripod 10 while adjusting the suction force of the suction cup 12 simultaneously. This integrated operation method greatly simplifies the operation steps of the debugging personnel and improves the convenience and efficiency of the work. At the same time, it also ensures that the debugging device can maintain excellent stability in various environments.

[0045] The implementation principle of a debugging device for a train water heater control box 3 in an embodiment of the present application is as follows: when debugging is required, the debugging personnel rotate the rotating shaft 9, and the rotating shaft 9 drives the tripod 10 to rotate to a vertical state. The roller 5 contacts the ground and pushes the cabinet 1 to move the cabinet 1 to the debugging position. Then, the rotating shaft 9 is rotated in the opposite direction. During the process of the rotating shaft 9 driving the tripod 10 to rotate to a horizontal state, the rotating shaft 9 drives the driving component 14, and the driving component 14 drives the piston block 132 to move in a direction away from the suction cup 12. When the caster is completely off the ground, the cabinet 1 is fixed to the floor of the carriage by the suction cup 12.

[0046] Then the debugging personnel place the control box 3 in the installation groove 21 and rotate the first screw 41. The first screw 41 drives the first clamping plate 43 to approach the control box 3. When the rubber pad 6 on the first clamping plate 43 is in close contact with the outer wall of the control box 3, the first screw 41 is stopped and the second screw 42 is rotated. The second screw 42 drives the second clamping plate 44 to approach the control box 3. When the rubber pad 6 on the second clamping plate 44 is also in close contact with the outer wall of the control box 3, the control box 3 is fixed between the first clamping plate 43, the second clamping plate 44 and the protective plate 7. Finally, the control box 3 is connected to the pipeline of the water heater in the cabinet 1, and the debugging operation is started.

[0047] When the train shakes, the control box 3 cannot be displaced due to the restrictions of the clamping assembly 4 and the mounting groove 21, and the stability of the control box 3 on the debugging device is improved.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
