Description

Technical Field

[0001] This invention relates to the field of valve body cleaning technology, and in particular to an automatic valve body drying device. Background Technology

[0002] Currently, the Type 120 railway freight car air brake control valve (hereinafter referred to as "120 valve") is a core component of freight car braking and is widely used in various railway freight cars. The product quality of the 120 valve directly affects the driving safety of railway freight cars. The 120 valve is mainly composed of a main valve body, an intermediate body, an emergency valve, and a release valve. Among them, the main valve body has a complex internal structure and a very small air passage orifice.

[0003] After cleaning, the main valve body will have a large amount of residual water stains. If these are not thoroughly removed, corrosion or air circuit blockage may occur, affecting the valve's performance and posing a safety hazard to railway freight cars. Currently, the valve body is manually cleaned using an air gun. This method has many drawbacks, including low efficiency, high labor intensity, difficulty in guaranteeing drying quality, and excessive noise. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic valve body drying device to address the above-mentioned problems. By using a special air knife to blow high-pressure hot air onto the valve body, residual water stains on all surfaces and inside the valve body are blown away or evaporated more quickly, thereby improving efficiency.

[0005] This invention is achieved through the following scheme:

[0006] An automatic valve body drying device includes a turntable for placing the valve body, a motor connected to the turntable, an air knife assembly for blowing air onto the valve body, and a blower connected to several air knife assemblies.

[0007] And a contouring mechanism, which supports the reciprocating mechanism and drives the reciprocating mechanism to reciprocate in a direction away from or close to the center point of the turntable base;

[0008] The air knife assembly includes a first air knife assembly, a second air knife assembly, an air nozzle assembly, and a fixed air knife assembly;

[0009] The first air knife assembly is located beside the turntable and moves up and down along the guide rail with the up-and-down reciprocating mechanism, with the air outlet direction facing the side of the valve body to be bleed; the up-and-down reciprocating mechanism is combined with the left-and-right reciprocating mechanism; the second air knife assembly is located above the turntable and moves left and right along the guide rail with the left-and-right reciprocating mechanism, with the air outlet direction facing down and towards the top surface of the valve body to be bleed; the air nozzle assembly is located on one side of the first air knife assembly and moves horizontally to extend into a preset area of ​​the valve body for blowing; the fixed air knife assembly is installed on one side of the turntable.

[0010] Furthermore, the range of movement of the first air knife assembly is not less than the height of the valve body, the range of movement of the second air knife assembly is not less than the length of the valve body, and the length of the air outlet of the first air knife assembly and the air outlet of the second air knife assembly is not less than the width of the valve body.

[0011] Furthermore, a contouring roller is provided at one end of the contouring mechanism near the turntable. The contouring roller contacts the edge of the turntable base, and the contouring roller keeps the distance between the air outlet of the first air knife assembly and the side of the valve body constant.

[0012] Furthermore, the second air knife assembly also includes an extension arm, the front end of which is provided with an air outlet.

[0013] Furthermore, the upper part of the vertical reciprocating mechanism is combined and installed with the horizontal reciprocating mechanism through a connector to form a cross-shaped structure; the connector adjusts the horizontal reciprocating mechanism so that the relative position of the horizontal reciprocating mechanism with respect to the turntable can be changed.

[0014] Furthermore, the left and right reciprocating mechanism includes a reciprocating section and an adjusting section. The reciprocating section provides a reciprocating operating range for the second air knife assembly, and the connecting member moves in the adjusting section to adjust the position of the left and right reciprocating mechanism.

[0015] The present invention also provides a drying method based on the above-mentioned automatic valve body drying device, comprising the following steps:

[0016] Step 1: Set process parameters such as number of cycles, blowing sequence, air pressure and temperature. Move the left and right reciprocating mechanism and the up and down reciprocating mechanism to the initial position and place the valve body on the turntable.

[0017] Step 2: The second air knife assembly blows air onto the top of the valve body;

[0018] Step 3: The turntable rotates or stops under the drive of the motor, and the first air knife assembly blows on the side of the valve body so that the upper cover, lower cover and relief valve mounting surface of the valve body can be blown into place.

[0019] Step 4: Rotate the turntable until the nozzle assembly is aligned with the preset area of ​​the valve body. Then, stop rotating the turntable and insert the nozzle assembly into the preset area to perform a blowing operation. After the blowing operation in the preset area is completed, retract the nozzle.

[0020] Step 5: Remove the valve body, move it to the fixed air knife assembly, and blow air onto the bottom surface of the valve body.

[0021] Furthermore, steps three and four can be performed alternately. When the blowing surface is the upper or lower cover, the first air knife assembly pauses its operation when it reaches the preset area height position, and the air nozzle assembly extends into the preset area to perform the blowing operation. After completing the blowing of the preset area, the air nozzle is retracted. When the blowing surface is the relief valve mounting surface, the first air knife assembly continues its operation when it reaches the preset area height position, and the air nozzle assembly does not operate.

[0022] Furthermore, steps two and three are performed simultaneously, and steps two through four are repeated cyclically. This forms a complete blowing structure and method encompassing the second air knife assembly, the first air knife assembly, the fixed air knife assembly, and the nozzle assembly.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] Compared to current manual drying methods, this invention can establish a standardized operating procedure. Various process parameters, such as the number of cycles, blowing sequence, air pressure, and temperature, can be adjusted, thereby enabling the exploration of the optimal drying process and ensuring stable drying quality.

[0025] Compared to the current manual drying method, this invention can automatically complete the drying of all surfaces of the valve body and the inside of the valve sleeve. With the help of loading and unloading robots, the entire process can be automated.

[0026] Compared to the current manual cleaning method, the air knife of this invention has a wider blowing area. A single parallel movement relative to the valve surface can complete the drying process of the entire valve surface. Multiple air knife components can operate simultaneously, and the high-pressure hot air temperature can reach 50°C, which accelerates the evaporation of liquid and greatly improves the work efficiency.

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings.

[0036] The technical solution provided in this embodiment relates to an automatic valve body drying device, such as... Figures 1-2 As shown, it includes a turntable 1 for placing the valve body 8, a motor 9 connected to the turntable 1, an air knife assembly for blowing air onto the valve body 8, a blower 7 connected to several air knife assemblies, and a contouring mechanism 5, which supports the up-and-down reciprocating mechanism 2 and drives the up-and-down reciprocating mechanism 2 to reciprocate in a direction away from or close to the center point of the turntable base 101.

[0037] In some embodiments, the air knife assembly includes a first air knife assembly 201, a second air knife assembly 301, an air nozzle assembly 4, and a fixed air knife assembly 6. Specifically, the air outlets of the first air knife assembly 201 and the second air knife assembly 301 are flat nozzles.

[0038] In some embodiments, the first air knife assembly 201 is disposed beside the turntable 1 and can move up and down along the guide rail with the up-and-down reciprocating mechanism 2, with the air outlet direction facing the side of the valve body 8 to be bleed; the up-and-down reciprocating mechanism 2 and the left-and-right reciprocating mechanism 3 are assembled together; the second air knife assembly 301 is disposed above the turntable 1 and can move left and right along the guide rail with the left-and-right reciprocating mechanism 3, with the air outlet direction facing down and towards the top surface of the valve body 8 to be bleed; the air nozzle assembly 4 is disposed on one side of the first air knife assembly 201, specifically, as shown in... Figure 2 As shown, the air nozzle assembly 4 is mounted on the first air knife assembly 201 and moves with it, extending and retracting in the horizontal direction to enter the preset area of ​​the valve body 8 for blowing. Specifically, the preset area is the through hole of the sliding valve sleeve of the valve body 8. The position height of the air nozzle assembly 4 corresponds to the position height of the through hole of the sliding valve sleeve when the valve body 8 is placed on the turntable 1, and it can enter the through hole of the sliding valve sleeve to blow the various orifices inside the valve body. The fixed air knife assembly 6 is installed on one side of the turntable 1, with its lower end connected to the base 101 and its upper air outlet a certain distance away from the table surface of the turntable 1.

[0039] In some embodiments, the range of movement of the first air knife assembly 201 is not less than the height of the valve body 8, the range of movement of the second air knife assembly 301 is not less than the length of the valve body 8, and the length of the air outlet of the first air knife assembly 201 and the air outlet of the second air knife assembly 301 is not less than the width of the valve body 8, so that each surface of the entire valve body 8 to be blown can be covered.

[0040] In some embodiments, the air nozzle assembly 4 is disposed on one side of the first air knife assembly 201, that is, the air nozzle assembly 4 is independently disposed near the first air knife assembly.

[0041] In some embodiments, the second air knife assembly 301 further includes an extension arm 302, with an air outlet at the front end of the extension arm 302.

[0042] In some embodiments, such as Figure 2 As shown, the upper part of the vertical reciprocating mechanism 2 is combined and installed with the horizontal reciprocating mechanism 3 through a connector to form a cross-shaped structure; the connector adjusts the horizontal reciprocating mechanism 3 so that the relative position of the horizontal reciprocating mechanism 3 with the turntable 1 can be changed.

[0043] In some embodiments, the left and right reciprocating mechanism 3 includes a reciprocating section 303 and an adjusting section 304. The reciprocating section 303 provides a reciprocating operating range for the second air knife assembly 301. The connecting member moves in the adjusting section 304 to adjust the position of the left and right reciprocating mechanism 3, thereby adjusting the height of the left and right reciprocating mechanism 3 so that the second air knife assembly 301 is directly above the valve body 8, and the blowing range of the air outlet of the second air knife assembly 301 can cover the top surface of the valve body 8.

[0044] In some embodiments, a drying method for an automatic valve body drying device includes the following steps:

[0045] Step 1: Set process parameters such as number of cycles, blowing sequence, air pressure and temperature. Move the left and right reciprocating mechanism 3 and the up and down reciprocating mechanism 2 to their initial positions and place the valve body 8 on the turntable 1.

[0046] Step 2: The second air knife assembly 301 blows air onto the top of the valve body 8;

[0047] Step 3: The turntable 1 rotates or stops under the drive of the stepper motor 9, and the first air knife assembly 201 blows the side of the valve body 8 so that all three surfaces of the valve body 8 to be blown can be blown into place.

[0048] Step 4: Rotate the turntable 1 until the air nozzle assembly 4 is aligned with the through hole of the valve sleeve of the valve body 8 and then stop rotating. The air nozzle assembly 4 extends into the through hole of the valve sleeve and blows through each orifice in the valve body. After blowing is completed, the air nozzle is retracted.

[0049] Step 5: Take out the valve body 8, move it parallel to the fixed air knife assembly 6, and blow the bottom surface of the valve body 8.

[0050] In some embodiments, steps three and four can be performed alternately. When the blowing surface is the upper cover surface 801 or the lower cover surface 802, the first air knife assembly 201 pauses its operation when it reaches the preset area height position, and the air nozzle assembly 4 extends into the preset area to perform the blowing operation. After the blowing of the preset area is completed, the air nozzle is retracted. When the blowing surface is the relief valve mounting surface 803, the first air knife assembly 201 continues to operate when it reaches the preset area height position, and the air nozzle assembly 4 does not operate.

[0051] In some embodiments, steps two and three are performed simultaneously, and steps two through four are performed cyclically.

[0052] In some embodiments, such as Figures 1-2As shown, the valve body 8 is placed on the turntable 1. Specifically, the turntable 1 has a hollow design to facilitate liquid drainage during the drying process. The turntable 1 can rotate 360 ​​degrees, and its power source is a stepper motor 9. Above the turntable 1 is a second air knife assembly 301 that can reciprocate left and right, and in front of the turntable 1 is a first air knife assembly 201 that can reciprocate up and down. The reciprocating motion can be uniform, and the movement speed and the flow rate of high-pressure hot air are controlled by a damping speed equalizer and a throttle valve. A fixed air knife assembly 6 is set on the base 101 below the turntable 1. The first air knife assembly 201, the second air knife assembly 301, and the fixed air knife assembly 6 all ensure that the blowing surface covers the entire valve body 8. In addition, there is an air nozzle assembly 4, which includes an air nozzle and an insertion mechanism. As a dedicated insertion drying mechanism for the valve body 8, it can extend into the through hole of the valve sleeve of the valve body 8 to further blow the orifice inside the valve body. The working components that blow air onto the top surface of the valve body 8 are the left-right reciprocating mechanism 3 and the second air knife assembly 301 on the left-right reciprocating mechanism 3. The working components that blow air onto the side surface of the valve body 8 are the up-down reciprocating mechanism 2 and the first air knife assembly 201 on the up-down reciprocating mechanism 2. The lower part of the up-down reciprocating mechanism 2 is connected to the contouring mechanism 5. The contouring mechanism is provided with a contouring roller at one end near the base of the turntable 1. The contouring roller 501 contacts the base of the turntable 1. The first air knife assembly 201, the second air knife assembly 301, the air nozzle assembly 4 and the contouring mechanism 5 are all provided with cylinders and the cylinders are speed adjustable. The air outlets of the first air knife assembly 201 and the second air knife assembly 301 are both facing the valve body 8.

[0053] In some embodiments, when the turntable 1 rotates, the contouring roller 501 contacts the base of the turntable 1, and the contouring mechanism 5 drives the up-and-down reciprocating mechanism 2 to perform contouring motion, ensuring that the first air knife assembly 201 maintains the same distance from the three surfaces to be blown on the side of the valve body 8; Figure 3 As shown, specifically, the valve body 8 includes an upper cover surface 801, a lower cover surface 802, a relief valve mounting surface 803, a front cover surface 804, an intermediate body mounting surface 805, and a marking surface 806. The three surfaces to be blown are the upper cover surface 801, the lower cover surface 802, and the relief valve mounting surface 803.

[0054] In some embodiments, the drying device is provided with a soundproof cover, which has an automatic door to form a drying chamber. Compared with the current manual drying method, the soundproof cover can reduce the noise when the high-pressure air is blown out. The stepper motor 9 and the blower 7 are both located outside the drying chamber, and the driving device inside the drying chamber is a cylinder, which avoids the use of electrical equipment in a humid and confined environment and reduces safety risks.

[0055] In some embodiments, a drying method based on an automatic valve body drying device includes the following steps: Before the drying operation, the blower 7 is started to preheat and the automatic door of the soundproof cover is opened. The valve body 8 to be dried is placed on the turntable 1 with the front cover 804 facing up. After placement, the automatic door of the soundproof cover is closed. The turntable rotates and the automatic drying begins. The second air knife assembly 301 at the top moves back and forth to blow on the front cover 804 of the valve body 8. The first air knife assembly 201 on the side moves back and forth to blow on the upper cover 801, lower cover 802 and relief valve mounting surface 803 of the valve body 8. Then the turntable rotates at a certain angle so that the air nozzle assembly 4 is aligned with the sliding valve sleeve and inserted into the sliding valve sleeve to blow. The above operation is repeated. Finally, when the valve body 8 is taken out, the fixed air knife assembly 6 blows on the bottom surface, i.e., the intermediate body mounting surface 805, for a certain period of time, thus completing the entire drying operation.

[0056] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
