Description

Technical Field

[0001] This utility model relates to the field of cylinder technology, and more specifically, to a pressure testing device for linear stroke cylinders. Background Technology

[0002] A linear stroke cylinder is a cylinder in which the piston makes a linear reciprocating motion. Its output motion is a linear motion along the cylinder axis. Linear stroke cylinders are used in many places in life, such as gate valves and stop valves.

[0003] Before using a linear stroke cylinder, it is usually necessary to perform a pressure test. During the pressure test, the piston rod will extend and retract. If there is a problem with the quality of the cylinder, the piston rod may even be ejected, which is very dangerous. Utility Model Content

[0004] In summary, to overcome the shortcomings of the prior art, this utility model provides a safer pressure testing device for linear stroke cylinders.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure testing device for a linear stroke cylinder, comprising a support base, a clamping mechanism, and a protective cover. Two clamping mechanisms are provided, each located on one side of the support base in the width direction. Each clamping mechanism includes a first telescopic mechanism and a first push plate. The first telescopic mechanism controls the first push plate to move towards the support base. The protective cover is located on one side of the support base in the length direction, and a protective top cover is provided above the support base.

[0006] With this setup, the cylinder is placed on the support base, with the air inlet and outlet facing upwards. The first telescopic mechanism is then controlled to push the first push plate to clamp and stabilize the cylinder from both sides. After that, an air pipe can be connected to test the cylinder. During the test, the cylinder's piston rod will move inside the protective cover. If there is a quality problem with the cylinder that causes the piston rod to eject, the piston rod will pop out inside the protective cover and hit the inner wall of the cover. The top of the protective cover is also equipped with a protective cover, so even if it rebounds, it will not pop out from above and will not hit the tester, making it safer.

[0007] Furthermore, the clamping mechanism also includes a second telescopic mechanism and a second push plate. The second telescopic mechanism and the second push plate are located on the side of the support seat facing away from the protective cover. The second telescopic mechanism controls the second push plate to move toward the protective cover. A baffle is provided on the top surface of the support seat facing the protective cover.

[0008] With this configuration, the second telescopic mechanism will push the second push plate from the tail of the cylinder to clamp the cylinder against the baffle on the other side, which is more stable and can also position the cylinder so that its telescopic rod is located just below the protective top cover. This eliminates the need to deliberately align the position when placing it, making the operation more convenient.

[0009] Furthermore, there are two baffles, and a gap is provided between the two baffles.

[0010] With this configuration, the two baffles are pressed down by the cylinders from both sides simultaneously, resulting in a larger area and greater stability. Furthermore, the gap between the two baffles provides space for the piston rod to extend and retract, without affecting its extension and retraction test.

[0011] Furthermore, it also includes a third telescopic mechanism, which controls and changes the distance between the first push plate and the top surface of the support base.

[0012] With this configuration, the third telescopic machine can change the relative distance between the first push plate and the support base. This allows the first push plate to press the cylinder of different sizes into the appropriate position to clamp it, making it more stable. A base can be installed under the first telescopic machine to raise its height.

[0013] Furthermore, the output shaft of the third telescopic mechanism is connected to the support base.

[0014] With this configuration, the height of the support base can be changed according to the size of the cylinder, so that it always stays close to the protective top cover while changing position in conjunction with the first push plate, making it safer.

[0015] Furthermore, the top surface of the first push plate is provided with a top plate on one side of the top of the support base.

[0016] With this configuration, the top plate can block the cylinder from the top, preventing the cylinder from vibrating and coming off during testing if there is a quality problem, which is safer. In addition, the top plate is set on the two first push plates, and there is no obstruction in the middle, so the cylinder interface will still be exposed and will not affect the pressure test process.

[0017] Furthermore, the protective cover has a cushioning pad on the side facing the support base.

[0018] With this design, the cushioning pad can be made of soft material, reducing the impact force during a collision and preventing ejection, thus making it safer.

[0019] Furthermore, the protective top cover is provided with several viewing slots.

[0020] With this design, the viewing slot can be used to observe the internal situation and the appearance of the piston rod. At the same time, the viewing slot is small enough that the piston rod cannot pass through it, so it will not affect safety. Using a slotted design instead of a transparent window can prevent the transparent window from being broken by impact, making it safer. Attached Figure Description

[0025] This specific embodiment is merely an explanation of the present embodiment and is not intended to limit the present embodiment. After reading this specification, those skilled in the art can make modifications to the present embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present embodiment.

[0026] Referring to the accompanying drawings, this utility model provides the following technical solution: a pressure testing device for a linear stroke cylinder, comprising a support base 1, a clamping mechanism 2, and a protective cover 3. Two clamping mechanisms 2 are provided, respectively located on both sides of the support base 1 in the width direction. Each clamping mechanism 2 includes a first telescopic mechanism 201 and a first push plate 202. The first telescopic mechanism 201 controls the first push plate 202 to move towards the support base 1. The protective cover 3 is located on one side of the support base 1 in the length direction. A protective top cover 301 is provided on the protective cover 3 above the support base 1. The telescopic mechanism can use cylinders, hydraulic cylinders, electric push rods, etc. Other telescopic mechanisms described herein are similar. The above configuration is not limiting; the device of this application can also be placed vertically.

[0027] With this setup, the cylinder is placed on the support base 1, with the air inlet and outlet facing upwards. Then, the first telescopic mechanism 201 is controlled to push the first push plate 202 to clamp and stabilize the cylinder from both sides. After that, the air pipe can be connected to test the cylinder. During the test, the piston rod of the cylinder will move inside the protective cover 3. If there is a quality problem with the cylinder that causes the piston rod to eject, the piston rod will pop out inside the protective cover 3 and hit the inner wall of the protective cover 3. The top of the protective cover 3 is also equipped with a protective top cover 301, so even if it rebounds, it will not pop out from the top and will not hit the tester, making it safer.

[0028] In a preferred embodiment, the clamping mechanism 2 further includes a second telescopic mechanism 203 and a second push plate 204. The second telescopic mechanism 203 and the second push plate 204 are located on the side of the support base 1 facing away from the protective cover 3. The second telescopic mechanism 203 controls the second push plate 204 to move toward the protective cover 3. A baffle 101 is provided on the top surface of the support base 1 facing the protective cover 3.

[0029] With this configuration, the second telescopic mechanism 203 will push the second push plate 204 to clamp the cylinder against the baffle 101 on the other side from the tail of the cylinder, which is more stable and can also position the cylinder so that the telescopic rod is located just below the protective top cover 301. This eliminates the need to deliberately align the position when placing the cylinder, making operation more convenient.

[0030] In this preferred embodiment, there are two baffles 101, and a gap is provided between the two baffles 101.

[0031] With this configuration, the two baffles 101 are pressed down by the cylinders from both sides, resulting in a larger area and greater stability. Furthermore, the gap between the two baffles provides space for the piston rod to extend and retract, without affecting its extension and retraction test.

[0032] In a preferred embodiment, a third telescopic mechanism 4 is also included, which controls and changes the distance between the first push plate 202 and the top surface of the support base 1.

[0033] With this configuration, the third telescopic machine 4 can change the relative distance between the first push plate 202 and the support base 1. This allows the first push plate 202 to press the cylinder of the corresponding size into the appropriate position to clamp it, making it more stable. A base can be installed under the first telescopic machine 201 to raise its height.

[0034] In this preferred embodiment, the output shaft of the third telescopic machine 4 is connected to the support base 1.

[0035] With this configuration, the height of the support base 1 can be changed according to the size of the cylinder, so that while it changes position in conjunction with the first push plate 202, it always stays close to the protective top cover 301, making it safer.

[0036] In a preferred embodiment, the top surface of the first push plate 202 is provided with a top plate 2021 on one side of the top of the support base 1.

[0037] With this configuration, the top plate 2021 can block the cylinder from the top, preventing the cylinder from vibrating and coming off from above during testing if there is a quality problem, which is safer. In addition, the top plate 2021 is set on the two first push plates 202, and there is no obstruction in the middle, so the cylinder interface will still be exposed and will not affect the pressure test process.

[0038] In this preferred embodiment, the protective cover 3 is provided with a buffer pad 302 on the side facing the support base 1.

[0039] With this design, the cushioning pad 302 can be made of soft material, reducing the impact force during a collision and preventing ejection, thus making it safer.

[0040] In this preferred embodiment, the protective top cover 301 is provided with a plurality of viewing slots 3011.

[0041] With this design, the viewing slot 3011 can be used to observe the internal situation and the appearance of the piston rod. At the same time, the viewing slot 3011 is small in size and will not allow the piston rod to pass through, so it will not affect safety. Using a slotted form instead of a transparent window can prevent the transparent window from being broken by impact, making it safer.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be included within the scope of protection of the present invention.
