Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sealing ring detection, in particular to a measuring tool for quickly testing O-shaped rubber rings. BACKGROUND

[0002] With the need of oil field construction, each measurement station and oil and gas transfer station needs to transport crude oil and oil-containing injection water through large-diameter non-metal pipelines. The use of large-diameter deep-drawn T-shaped thread glass steel pipelines is large, and the current oil field requires large-diameter glass steel pipelines to be designed with double sealing to ensure the sealing safety performance of the pipeline. The amount of O-shaped rubber sealing rings required here is twice that of the original amount. The size of the O-shaped rubber sealing ring directly affects the installation effect and subsequent sealing performance of the pipeline during use. Therefore, the demand for root inspection of the O-shaped rubber sealing ring is increasingly prominent.

[0003] The thickness of the pipeline sealing ring is 7.2±0.1mm, and the inner diameter size is 311.2-311.8mm. After the sealing ring is opened, it will be vulcanized by heating, and its thickness will remain relatively unchanged within the error range due to thermal expansion and contraction. However, due to the large base of the inner and outer diameter sizes, the inner and outer diameter sizes may exceed the error range, so the inner and outer diameter sizes of the sealing ring need to be accurately detected. At present, the only way to measure the inner diameter size of the O-shaped rubber sealing ring with a diameter of 250mm or more is to use a π ruler to detect the inner and outer diameters of the O-shaped rubber sealing ring and a caliper to detect the linear diameter of the O-shaped rubber sealing ring. This method is not only slow, but also the tightness of the π ruler will affect the size of the value due to the elasticity of the rubber material, thereby affecting the accuracy of the size value and causing inconvenience to the inspection work. When facing the inspection of thousands of O-shaped rubber sealing rings, it is impossible to detect them one by one.

[0004] To this end, the Chinese patent with publication number CN220625194U discloses a sealing ring measuring jig and detection equipment. The sealing ring measuring jig comprises a main body, a first through slot, a second through slot and an annular groove formed on the main body, wherein the two ends of the first through slot and the two ends of the second through slot respectively penetrate the side surface of the main body to form an observation port on the side surface of the main body, and the first through slot and the second through slot are arranged vertically. The first through slot and the second through slot respectively penetrate the groove wall of the annular groove, and the annular groove is used to place the sealing ring. The annular groove is used to place the sealing ring, so that the detection mechanism can shoot and detect the sealing ring from top to bottom, and the inner diameter and outer diameter of the sealing ring can be detected. The first through slot and the second through slot respectively penetrate the groove wall of the annular groove, and the side surface of the sealing ring can be observed through the observation port. Therefore, the detection mechanism can shoot and detect the side surface of the sealing ring in the horizontal direction through the observation port to detect the thickness of the sealing ring. The measuring jig can place the sealing ring through the annular groove, and detect the inner diameter and outer diameter of the sealing ring by shooting the sealing ring from top to bottom through the detection mechanism. Although this detection method can achieve detection, the detection efficiency for a large number of sealing rings is not high. The sealing ring is placed in the annular groove by manual operation, and then taken out after shooting and detection. The efficiency is too low, and other equipment needs to be set up to store qualified sealing rings during the detection process.

[0005] The Chinese patent with publication number CN213422040U discloses a sealing ring size detection device. The sealing ring to be detected is placed around the containing hole on the support plate. The air blowing and sucking pump is opened. The air blowing and sucking pump pumps external gas into the first air hole. The external gas enters the second air hole through the first air hole. The gas enters the space at the top of the detection cone sleeve and the support sleeve through the second air hole. The air pressure increases, pushing the detection cone sleeve to move upward along the outer wall of the fixed sleeve. During the upward movement of the detection cone sleeve, the sealing ring to be detected is sleeved on the detection cone sleeve. The height of the sealing ring to be detected on the detection cone sleeve is identified. The sealing ring to be detected within the qualified line is a qualified sealing ring, thereby achieving the purpose of detecting the inner diameter size of the sealing ring. The air blowing and sucking pump is adjusted to extract the gas in the space at the top of the detection cone sleeve and the support sleeve. The detection cone sleeve moves downward along the outer wall of the fixed sleeve. During the downward movement of the detection cone sleeve, the sealing ring to be detected is blocked by the support plate. The sealing ring and the detection cone are separated. The sealing ring falls on the support plate. The sealing ring to be detected is simple to put and take. The sealing ring can be directly placed on the support plate and taken off from the support plate. The detection device can only measure the inner diameter of the sealing ring. The measurement process needs to go through the air blowing and sucking of the air pump and the lifting of the detection cone sleeve. The qualified products need to be manually taken out and stored separately. The process is complex and inefficient. It cannot handle batch detection. Other equipment needs to be set up to store qualified sealing rings during the detection process.

[0006] Chinese patent publication No. 102072690A discloses a sealing ring detection tool; including a sealing ring detection block 2, a sealing ring detection hole 3 is arranged in the sealing ring detection block 2 and matched with the sealing ring, one end of the sealing ring detection hole 3 has an inclined angle, the open sealing ring to be detected is put into the sealing ring detection hole 3, and the opening size of the open sealing ring is measured to quickly distinguish the qualified product and the unqualified product.

DETAILED DESCRIPTION

[0023] The principles and features of the invention are described below, and the examples are only used to explain the invention and not to limit the scope of the invention.

[0024] Example 1 As Figures 1-5 A measuring tool for quickly checking O-shaped rubber rings, comprising: A storage cylinder 1, which is an up-down through opening structure, and has a plurality of hanging rods 2 distributed circumferentially on the inner side, one end of each hanging rod 2 is fixedly connected to the storage cylinder 1, and the other end is inclined upward; An outer ring 3, which is coaxially connected to the upper opening of the storage cylinder 1, and the inner side is an outer detection surface 31 for detecting the outer diameter of the sealing ring; An inner disc 4, which is concentrically arranged on the inner side of the outer ring 3, and the outer side is an inner detection surface 41 for detecting the inner diameter of the sealing ring, and the outer detection surface 31 and the inner detection surface 41 form a passage for the sealing ring to pass through; A guide 5, the upper end of which is coaxially fixedly connected to the lower side of the inner disc 4, and the lower end is detachably connected to the other end of any hanging rod 2.

[0025] The beneficial effect of the embodiment is that during the detection process, the artificial directly places the to-be-detected sealing ring between the outer ring 3 and the inner disc 4. Because the thickness formed by the opening of the sealing ring is always consistent, only the size of the inner diameter and the outer diameter will change. Therefore, when the to-be-detected sealing ring is placed in the passage between the outer ring 3 and the inner disc 4, if the sealing ring can pass through the passage, it is qualified; if it cannot pass through the passage, it is unqualified. When it is qualified, the sealing ring passes through the passage and falls into the storage cylinder 1, and under the guidance of the guide piece 5 and the hanging rod 2, it slides along the guide piece 5 and hangs on the hanging rod 2, so as to store the qualified sealing ring while detecting, without the need to pick out and take away the sealing ring in the annular groove in the prior art, and the next sealing ring can be directly detected, reducing the detection steps and improving the efficiency.

[0026] When it is unqualified, the sealing ring cannot pass through the passage and is retained on the outer ring 3 and / or the inner disc 4, and can be directly taken away, without the need to pick out the sealing ring from the annular groove in the prior art. By adopting this detection method, the storage cylinder 1 supports the outer ring 3 and the inner disc 4 while storing the qualified sealing ring after long-time detection, without the need to use other tools for storage, reducing the required working space, and enabling batch storage and processing of the qualified sealing ring, thereby improving the working efficiency.

[0027] In addition, after a hanging rod 2 is hung with full sealing rings, the inner disc 4 can be connected to the outer ring 3, and then a force is applied to the outer ring 3 to drive the inner disc 4 and the guide piece 5 to rotate synchronously, so that the guide piece 5 is connected to the other end of the adjacent other hanging rod 2, and after ensuring that the adjacent other hanging rod 2 stably supports the guide piece 5, the connection between the inner disc 4 and the outer ring 3 is released, and the next stage of sealing ring detection operation is performed. In this way, the inner wall of the storage cylinder 1 can be hung with qualified sealing rings in a circumferential direction. Compared with the direct stacking storage method of the prior art, this storage method has higher space utilization and storage efficiency.

[0028] During the detection, the lower end of the guide piece 5 is detachably connected to the other end of any hanging rod 2, and the hanging rod 2 and the guide piece 5 form support for the inner disc 4, so as to ensure the stable installation of the inner disc 4.

[0029] Each hanging rod 2 is arranged on the same circumference, and one end of the hanging rod 2 is fixedly connected to the inner wall of the storage cylinder 1.

[0030] Embodiment 2 As Figures 2-4 On the basis of embodiment 1, the other end of each hanging rod 2 is provided with a bayonet 21, and the lower end of the guide piece 5 is fixedly connected with a clamping block 521 adapted to be clamped in the bayonet 21.

[0031] The beneficial effect of the preferred solution in the above embodiment is that by precisely clamping the clamping block 521 into the clamping opening 21 at the end of the hanging rod 2, a reliable plug-in locking structure is formed, which not only realizes the quick assembly and accurate positioning between the hanging rod 2 and the guide 5, but also significantly enhances the connection stability of the two under stress.

[0032] The load borne by the guide 5 is effectively transmitted and dispersed, so that the hanging rod 2 can provide uniform and firm support for the guide 5, thereby avoiding shaking or displacement in the overall structure and improving the rigidity and durability of the system.

[0033] On the basis of the above embodiment, a slope is formed on the side of the clamping opening 21 and / or the clamping block 521. The clamping block 521 rotating smoothly enters the clamping opening 21.

[0034] Embodiment 3 As Figure 4 On the basis of embodiments 1 and 2, the inner wall of each clamping opening 21 is fixedly connected with a plurality of elastic balls 211, and the clamping block 521 is provided with a clamping groove 522 adapted to the elastic balls 211 and allowing the elastic balls 211 to deform and enter.

[0035] The beneficial effect of the preferred solution in the above embodiment is that when the clamping block 521 is precisely clamped into the clamping opening 21 at the end of the hanging rod 2, the elastic balls 211 restore and enter the clamping groove 522, forming a limit to the clamping block 521 to prevent the clamping block 521 from disengaging the clamping opening.

[0036] It should be noted that on the basis of the above embodiment, the slope on the movable clamping block 521 can exert pressure on the elastic balls 211, causing the elastic balls 211 to deform, to ensure that the clamping block 521 is smoothly installed in place.

[0037] As one of the parallel solutions, the elastic ball 211 is a hollow spherical structure that can deform and be compressed under stress to ensure smooth passage of the clamping block 521.

[0038] As the second parallel solution, the inner wall of the clamping opening 21 is provided with an elastic groove, a spring is arranged in the elastic groove, and the elastic ball 211 is fixed to the end of the spring to push the elastic ball 211 out of the elastic groove by the spring, forming a limit to the clamping block 521. Under natural conditions, the volume of the elastic ball 211 pushed out of the elastic groove by the natural spring does not exceed two-thirds of the volume of the ball, so that the stressed elastic ball 211 can form a positive extrusion on the spring.

[0039] Embodiment 4 As Figures 2-4On the basis of the embodiments 1-3, the guide 5 comprises a fixed rod 51 vertically arranged coaxially with the inner disc 4 and a guide plate 52 arranged obliquely, the upper end of the fixed rod 51 is fixedly connected coaxially with the inner disc 4, the upper end of the guide plate 52 is fixedly connected with the lower end of the fixed rod 51, and the lower end of the guide plate 52 is detachably connected with the other end of any hanging rod 2.

[0040] The beneficial effect of the preferred solution in the above embodiments is that, in the detection process, the guide plate 52 forms a transition between the fixed rod 51 and the hanging rod 2 to receive and guide the falling and qualified sealing ring, and the qualified sealing ring slides along the guide plate 52 and is hung on the hanging rod 2, so that the qualified sealing ring is received while being detected, and the sealing ring in the annular groove in the prior art does not need to be pried out and taken away, and the next sealing ring can be directly detected, reducing the detection steps and improving the efficiency. At the same time, the guide 5 connected with the hanging rod 2 further forms a stable support for the inner disc 4.

[0041] On the basis of the above embodiments, the clamping block 521 is fixed to the lower end of the guide plate 52.

[0042] Embodiment 5 As Figures 2-4 On the basis of the embodiments 1-4, the inclination angle of the guide plate 52 is the same as the inclination angle of the hanging rod 2, and the upper side of the guide plate 52 and the hanging rod 2 are located on the same curved surface.

[0043] The beneficial effect of the preferred solution in the above embodiments is that the sealing ring is smoothly slid into the hanging rod 2 through the guidance of the guide plate 52.

[0044] Embodiment 6 As Figure 2 And Figure 3 On the basis of the embodiments 1-5, the outer ring 3 is transversely provided with a plug hole 32, and a plug rod 33 is inserted into the plug hole 32; the side wall of the inner disc 4 is provided with an inner threaded hole 42 opening towards the plug hole 32, and the plug rod 33 is threadedly connected to the inner threaded hole 42.

[0045] The beneficial effect of the preferred solution in the above embodiments is that when it is necessary to rotate and connect the guide 5 with different hanging rods 2, the inner disc 4 can be stably installed by inserting the plug rod 33 into the plug hole 32 and threadedly connecting it to the inner threaded hole 42, until the guide 5 is rotated to the position and connected with the predetermined hanging rod 2, and then the plug rod 33 is taken out, so that the next round of sealing ring detection operation can be performed.

[0046] The opening of the plug hole 32 is chamfered to form a guide surface, and the end of the plug rod 33 is chamfered to form a conical structure to guide the smooth insertion of the plug rod 33.

[0047] Embodiment 7 As Figure 1 And Figure 2 On the basis of Embodiments 1-6, the outer circular ring 3 is fixedly connected with at least two overlapping arms 34, the end of each overlapping arm 34 is fixedly connected with an overlapping block 341, and the upper end of the storage cylinder 1 is provided with a ring groove 11, and the overlapping block 341 is adapted and slidingly connected to the ring groove 11.

[0048] The beneficial effect of the preferred scheme in the above embodiments is that the outer circular ring 3 is stably supported at the upper opening of the storage cylinder 1 by the overlapping arms 34, ensuring the smooth progress of the detection work.

[0049] And the overlapping block 341 is adapted and slidingly connected to the ring groove 11, so that the outer circular ring 3 can be rotated by applying force to it. On the basis of the above embodiments, rotating the outer circular ring 3 can make the guide 5 connect with different hanging rods 2.

[0050] Among them, the ring groove 11 is a "U" shaped opening structure. Specifically, the ring groove 11 can be a stepped groove or a dovetail groove to prevent the overlapping block 341 from coming off the ring groove 11 and ensure the stable installation of the outer circular ring 3.

[0051] Embodiment 8 As Figure 1 And Figure 2 On the basis of Embodiments 1-7, one of the overlapping arms 34 is fixedly connected with a hanging rod 342, the hanging rod 342 is fixedly connected with an obliquely extending clamping plate 343, and the clamping plate 343 can be rotated to be directly above any hanging rod 2.

[0052] The beneficial effect of the preferred scheme in the above embodiments is that the possibility of overlapping of the sealing rings on the hanging rod 2 is reduced by the clamping of the clamping plate 343.

[0053] Specifically, a space for hanging the sealing ring is formed between the clamping plate 343 and the hanging rod 2 directly below it, and when the thickness of the space does not exceed twice the thickness of the sealing ring, the sealing ring will not be able to overlap in the space.

[0054] On the basis of the above embodiments, the inner wall of the storage cylinder 1 is fixedly connected with a plurality of support rods 12, each of which is obliquely arranged and fixedly connected at the lower end to the storage cylinder 1 and at the upper end to the lower side of each hanging rod 2.

[0058] The beneficial effect of the preferred solution in the above embodiments is that the sealing ring guided downward by the outer guide surface 311 and the inner guide surface 411 can quickly enter the channel formed between the outer detection surface 31 and the inner detection surface 41 for the sealing ring to pass through, and the detection is quickly completed.
