Description

Technical Field

[0001] The utility model relates to the field of pressure vessels, and more particularly to a device for detecting the size of a container. Background Art

[0002] The internal size of a pressure vessel, especially the maximum inner diameter difference of the pressure vessel, that is, the difference between its maximum diameter and minimum diameter, has an important impact on the quality and safety performance of the pressure vessel, and is an important parameter that needs to be key-inspected and measured in the manufacture and regular inspection of pressure vessels. If the maximum inner diameter difference exceeds a certain limit, it will affect the balance of the force distribution of the cylinder body and its load-bearing capacity, may cause stress concentration and local damage, and may even cause deformation of the cylinder body of the container and lead to safety accidents in severe cases.

[0003] Therefore, it is very crucial to regularly detect the size of the container. Most of the existing pressure vessel detection devices can only be used for the centering detection of a single container opening. For different pressure vessels, it is impossible to effectively adjust the centering synchronously according to the size of the container diameter, resulting in a low application range of the detection device. Therefore, we make improvements and propose a device for detecting the size of a container. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a device for detecting the size of a container, which solves the problem that the existing device for detecting the size of a container cannot adaptively perform center positioning during use according to different container diameters.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] A device for detecting the size of a container includes a bearing seat and a guiding tube rotatably arranged at the center of the bearing seat through a bearing. A detection mechanism is inserted into the guiding tube. Positioning mechanisms are arranged at the edges of the top and bottom walls of the bearing seat. A transmission mechanism is commonly provided between the positioning mechanism and the guiding tube.

[0007] The positioning mechanism includes a swing arm automatically arranged on the surface of the bearing seat through a bearing and a gear connected to the end of the swing arm.

[0008] Wherein, the front end of the swing arm extends outward to form a positioning arm and is fixed with a positioning convex ball.

[0009] As a preferred technical solution of the present application, the transmission mechanism includes a toothed disc sleeved on the surface of the guiding tube and arranged in contact with the surface of the bearing seat. A guiding strip is wrapped outside the toothed disc for fixing to the bearing seat.

[0010] As a preferred technical solution of the present application, there are multiple guiding strips, and there are gaps between the multiple guiding strips.

[0011] The gear meshes with the corresponding toothed disc through a clearance.

[0012] As a preferred technical solution of the present application, a transmission arm is fixed on the surface of the gear located above, and a positioning platform is formed at one end of the transmission arm extending on the guiding strip.

[0013] As a preferred technical solution of the present application, a positioning bolt is threadedly inserted through the surface of the positioning platform, and a positioning hole adapted to the positioning bolt is provided on the surface of the guiding strip.

[0014] As a preferred technical solution of the present application, the detection mechanism includes an adjusting rod slidably inserted into the guiding tube and an infrared detection end connected to the end of the adjusting rod.

[0015] As a preferred technical solution of the present application, an adjusting handle is fixed to the top end of the adjusting rod.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] In the solution of the present application:

[0018] Through the provided positioning mechanism, when the transmission arm is rotated to drive the toothed disc to rotate, under the action of the guiding tube, the upper and lower toothed discs will rotate synchronously and mesh with the gears on their outer sides. When the gears rotate, they will synchronously drive the positioning arms and convex balls thereon through the swing arms to abut against the inner wall of the port of the pressure vessel. Thus, when performing inspections under different pressure vessels, adaptive central positioning can be achieved to increase the applicable range, and at the same time, the detection mechanism can be supported and positioned to meet its detection requirements.

[0035] Such as Figures 1 - 5As shown in the figure, this embodiment proposes a container size detection device, which includes a bearing seat 1 and a guiding tube 11 rotatably arranged at the center of the bearing seat 1 through a bearing. A detection mechanism 2 is inserted into the guiding tube 11. Positioning mechanisms 3 are provided at the edges of the top and bottom walls of the bearing seat 1. A transmission mechanism 4 is jointly provided between the positioning mechanism 3 and the guiding tube 11;

[0036] The positioning mechanism 3 includes a swing arm 31 automatically arranged on the surface of the bearing seat 1 through a bearing and a gear 32 connected to the end of the swing arm 31. Among them, a positioning arm 33 extends outward from the front end of the swing arm 31 and a positioning convex ball 39 is fixed;

[0037] The transmission mechanism 4 includes a toothed disc 41 sleeved on the surface of the guiding tube 11 and arranged in contact with the surface of the bearing seat 1. A guiding strip 42 is wrapped outside the toothed disc 41 for fixing with the bearing seat 1;

[0038] There are multiple guiding strips 42, and there is a gap 43 between the multiple guiding strips 42;

[0039] The gear 32 meshes with the corresponding toothed disc 41 through the gap 43;

[0040] A transmission arm 34 is fixed on the surface of the gear 32 located above. One end of the transmission arm 34 extends onto the guiding strip 42 to form a positioning platform 35;

[0041] A positioning bolt 36 is threadedly inserted through the surface of the positioning platform 35, and a positioning hole 37 adapted to the positioning bolt 36 is opened on the surface of the guiding strip 42;

[0042] When actually detecting a pressure vessel, after passing the detection mechanism 2 through the inside of the pressure vessel, rotate the transmission arm 34 to drive the toothed disc 41 to rotate. Since the two toothed discs 41 are connected by the guiding tube 11, the two synchronously rotating toothed discs 41 will respectively drive the gears 32 meshing with their outsides to rotate. After being subjected to the meshing force, the gears 32 will drive the swing arms 31 thereon and the positioning convex balls 39 thereon to expand outward synchronously. Due to the uniform and synchronous expansion operations of the upper and lower positioning arms 33, the detection mechanism 2 can be positioned at the center. When the transmission arm 34 rotates in place, rotate the positioning bolt 36 so that one end of it is inserted into the corresponding positioning hole 37 to form a positioning effect;

[0043] And after the positioning detection is completed, the positioning bolt 36 can be taken out and the transmission arm 34 can be vibrated in the reverse direction to drive the multiple positioning arms 33 to reset and be received outside the bearing seat 1 to form a state as Figure 2 shown in the figure;

[0044] The detection mechanism 2 includes an adjusting rod 21 slidably inserted into the guiding tube 11 and an infrared detection end 22 connected to the end of the adjusting rod 21. An adjusting handle 23 is fixed to the top of the adjusting rod 21. After the detection mechanism 2 is centered and positioned in the corresponding pressure vessel through the positioning mechanism 3, the depth of the adjusting rod 21 can be slidably adjusted on the surface of the guiding tube 11 to adjust the position of the infrared detection end 22 thereon. Similarly, the adjusting rod 21 can be rotated on the surface of the guiding tube 11, so as to axially adjust the horizontal detection angle of the infrared detection end 22 through the rotating adjusting rod 21, so as to realize the dimensional detection of the inner wall of the pressure vessel;

[0045] The principle of the infrared detection end 22 in this embodiment is to form a distance detection from the inner wall of the pressure vessel through the ranging infrared rays emitted by the infrared detection end 22, and the ranging principle is an existing technology that is mature and perfect.

[0046] The above embodiments are only used to illustrate the present invention rather than limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific embodiments. Therefore, any modification or equivalent replacement to the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
