Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical technology, and more specifically to a testing device for pressure vessels. Background Technology
[0002] A pressure vessel is a closed device used to store gases or liquids and operate under certain pressure; it is typically cylindrical. Pressure vessels are widely used in many industries such as chemical, petroleum, power, and food processing. Because they usually contain high-pressure media, they have extremely high requirements for safety and reliability.
[0003] Pressure vessels need to be inspected before leaving the factory. The main inspection items include visual inspection, thickness measurement, and non-destructive testing.
[0004] Visual inspection primarily involves inspectors checking the exterior of the container for obvious damage, corrosion, cracks, or other abnormalities. Additionally, it's crucial to confirm that all connections on the pressure vessel (such as flanges and bolts) are securely tightened.
[0005] Thickness measurement involves using an ultrasonic thickness gauge to measure the wall thickness of a pressure vessel and assess whether there is wall thinning due to corrosion or wear.
[0006] Non-destructive testing mainly involves ultrasonic testing, which detects internal defects in pressure vessels by emitting and receiving ultrasonic waves. This testing method is particularly suitable for inspecting weld quality.
[0007] As can be seen, the aforementioned multiple inspection procedures require inspection of various parts of the pressure vessel. Current inspection methods typically involve workers moving around the circumference of the pressure vessel, which is fixed in place, and are labor-intensive and prone to missing parts. Utility Model Content
[0008] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a pressure vessel testing device that offers high stability and low labor intensity during testing operations.
[0009] To achieve the above objectives, this utility model can be implemented through the following technical solutions:
[0010] A testing device for pressure vessels includes a frame, characterized in that it further includes a support base, a drive component, and a rotating assembly. The support base is fixedly connected to the frame, the rotating assembly is movably connected to the support base, the drive component is fixedly connected to the frame and connected to the rotating assembly, and the support base, drive component, and rotating assembly form a support unit. The number of support units is two, and the two support units are symmetrically arranged at both ends of the frame. When a pressure vessel is laid horizontally, its two sides can respectively abut against the rotating assembly of the corresponding support unit.
[0011] In the aforementioned testing device for pressure vessels, the rotating assembly includes an upper roller shaft and a lower roller shaft. The upper roller shaft is axially fixed at the upper part of the support base and can rotate relative to the support base. The lower roller shaft is axially fixed at the lower part of the support base and can rotate relative to the support base.
[0012] In the aforementioned testing device for pressure vessels, the support base is an isosceles right triangle, with one side of the support base in contact with and fixed to the frame surface, and the upper roller shaft and the lower roller shaft axially fixed at the two base corners of the support base, respectively.
[0013] In the aforementioned testing device for pressure vessels, the support base has an arc-shaped recessed clearance at its bottom edge.
[0014] In the aforementioned testing device for pressure vessels, the upper roller shaft extends out of the support seat.
[0015] In the aforementioned testing device for pressure vessels, the lower roller shaft extends out of the support seat.
[0016] In the aforementioned testing device for pressure vessels, the driving components are a motor and a gearbox, both of which are fixedly connected to the frame. The motor's shaft is connected to the gearbox, and the gearbox is connected to the upper and lower roller shafts.
[0017] In the aforementioned testing device for pressure vessels, a transmission gear set is connected to the support base. The transmission gear set has one input end and two output ends. The input end of the transmission gear set is connected to a reduction gearbox, and the two output ends of the transmission gear set are respectively connected to the upper roller shaft and the lower roller shaft.
[0018] In the aforementioned testing device for pressure vessels, the motor and gearbox are located on one side of the frame, and the aforementioned transmission gear set is located on the other side of the frame.
[0019] In the aforementioned testing device for pressure vessels, both the upper and lower rollers are made of flexible materials.
[0020] Compared with the prior art, this pressure vessel testing device has two support units respectively set at both ends of the frame. When the cylindrical pressure vessel is lying horizontally, it can be stably placed at the device, that is, the two support units are respectively abutting against the two sides of the pressure vessel.
[0021] Because the drive unit can rotate the rotating assembly at the support base, and the pressure vessel is connected to the rotating assembly on its outer side, the pressure vessel is not connected to the frame or the support base; instead, the side of the pressure vessel rests against the corresponding rotating assembly. When the drive unit rotates the rotating assembly, the pressure vessel located on it rotates accordingly.
[0022] As can be seen, once the pressure vessel is placed on this device, the rotating component allows the pressure vessel to swing at a set angle, thus facilitating various inspection operations performed by operators. These inspections include, but are not limited to, visual inspection, thickness inspection, and non-destructive testing. In other words, this inspection device is used to conveniently rotate the pressure vessel, thereby facilitating its inspection by operators. The specific inspection method used is not a technical problem that this invention aims to solve. Attached Figure Description

[0027] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.
[0028] like Figure 1 and Figure 2 As shown, the pressure vessel testing device includes a frame 1, a support base 2, a drive component 3, and a rotating assembly. The support base 2 is fixedly connected to the frame 1, the rotating assembly is movably connected to the support base 2, and the drive component 3 is fixedly connected to the frame 1 and connected to the rotating assembly. The support base 2, the drive component 3, and the rotating assembly form a support unit. There are two support units, which are symmetrically arranged at both ends of the frame 1. When a pressure vessel is laid horizontally, its two sides can respectively abut against the rotating assembly of the corresponding support unit.
[0029] The cylindrical pressure vessel to be tested is placed horizontally at this testing device.
[0030] Specifically, the two sides of the pressure vessel abut against the corresponding support units, which provide stable support for the horizontally lying pressure vessel.
[0031] Since the rotating component in the support unit is in contact with the outside of the pressure vessel, when the drive unit drives the rotating component to rotate, the pressure vessel can rotate along with it. During the rotation of the pressure vessel, it is convenient for operators to perform corresponding inspections on various parts of the pressure vessel.
[0032] In other words, this device can be understood more intuitively as a fixture used in the testing process.
[0033] The rotating assembly includes an upper roller shaft 4 and a lower roller shaft 5. The upper roller shaft 4 is axially fixed at the upper part of the support base 2 and can rotate relative to the support base 2. The lower roller shaft 5 is axially fixed at the lower part of the support base 2 and can rotate relative to the support base 2.
[0034] Both the upper roller 4 and the lower roller 5 abut against the side of the pressure vessel. The rotatable upper roller 4 and lower roller 5 not only reduce the contact area with the pressure vessel, but also drive the pressure vessel to rotate stably within the device. Of course, this rotation is slow and intermittent, mainly to accommodate operators performing various tests on the pressure vessel.
[0035] The applicant needs to reiterate that the testing device is not directly used to test pressure vessels; it is only used to facilitate the rotation of pressure vessels. The specific type of testing is not a technical problem that this patent application aims to solve.
[0036] The support base 2 is an isosceles right triangle, with one side of the support base 2 in contact with and fixed to the surface of the frame 1. The upper roller shaft 4 and the lower roller shaft 5 are respectively axially fixed at the two base corners of the support base 2.
[0037] The support base 2 has an arc-shaped recessed clearance notch 2a at its bottom edge.
[0038] The clearance notch 2a can effectively avoid the side of the pressure vessel and prevent the side of the pressure vessel from contacting the support 2.
[0039] The upper roller 4 extends out of the support seat 2 from its side.
[0040] The lower roller 5 extends out of the support seat 2 from its side.
[0041] Clearly, this structure not only ensures stable contact between the upper roller shaft 4, the lower roller shaft 5 and the pressure vessel, but also prevents the pressure vessel from contacting the support base 2.
[0042] The driving components 3 are a motor 6 and a gearbox 7. Both the motor 6 and the gearbox 7 are fixedly connected to the frame 1. The rotating shaft of the motor 6 is connected to the gearbox 7, and the gearbox 7 is connected to the upper roller shaft 4 and the lower roller shaft 5.
[0043] The gearbox is a prior art technology capable of outputting a set speed. It is a commercially available component, therefore, the specific structural and technical features of the gearbox will not be described in detail in the embodiments.
[0044] A transmission gear set 8 is connected to the support base 2. The transmission gear set 8 has one input end and two output ends. The input end of the transmission gear set 8 is connected to the reduction gearbox 7, and the two output ends of the transmission gear set 8 are connected to the upper roller shaft 4 and the lower roller shaft 5, respectively.
[0045] The motor 6 and the gearbox 7 are located on one side of the frame 1, and the transmission gear set 8 is located on the other side of the frame 1.
[0046] The transmission gear set 8 is a commercially sourced component; therefore, its specific gear composition will not be described in detail in the embodiments.
[0047] The transmission gear set 8 and the drive component 3 are located on both sides of the frame 1, which effectively improves the structural compactness of the entire device.
[0048] Both the upper roller 4 and the lower roller 5 are made of flexible materials.
[0049] In this embodiment, both the upper roller shaft 4 and the lower roller shaft 5 are made of rubber, which can increase the frictional resistance between the upper roller shaft, the lower roller shaft and the pressure vessel, and facilitate the upper roller shaft and the lower roller shaft to stably drive the pressure vessel to rotate.
[0050] This pressure vessel testing device has two support units located at both ends of the frame. When a cylindrical pressure vessel is laid horizontally, it can be stably placed on the device, with the two support units abutting against the two sides of the pressure vessel.
[0051] Because the drive unit can rotate the rotating assembly at the support base, and the pressure vessel is connected to the rotating assembly on its outer side, the pressure vessel is not connected to the frame or the support base; instead, the side of the pressure vessel rests against the corresponding rotating assembly. When the drive unit rotates the rotating assembly, the pressure vessel located on it rotates accordingly.
[0052] As can be seen, once the pressure vessel is placed on this device, the rotating component allows the pressure vessel to swing at a set angle, thus facilitating various inspection operations performed by operators. These inspections include, but are not limited to, visual inspection, thickness inspection, and non-destructive testing. In other words, this inspection device is used to conveniently rotate the pressure vessel, thereby facilitating its inspection by operators. The specific inspection method used is not a technical problem that this invention aims to solve.
[0053] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
[0054] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
