Description

Technical Field

[0001] The utility model belongs to the technical field of bending and straight pipe sampling detection and measurement. Specifically, it particularly relates to a heat-resistant and wear-resistant bending and straight pipe angle sampling detection and measurement device. Background Technique

[0002] The bending and straight pipe with wear-resistant and heat-resistant characteristics is also called an elbow, also known as a turning connecting piece. Its main function is to connect two parts in different orientations. Normally, after the bending and straight pipe is processed, it needs to be sampled and detected, mainly for sampling and detecting the angle of the bending and straight pipe to ensure product accuracy.

[0003] Among them, Chinese Patent CN202021647552.9 discloses an oil pipe joint elbow angle detection tooling, including an L-shaped base. One side of the upper end surface of the L-shaped base is fixedly installed with a positioning seat and a limiting seat. The upper end surfaces of the positioning seat and the limiting seat are respectively provided with a positioning groove and a limiting groove. Both the front and rear sides of the upper end surface of the L-shaped base and between the positioning seat and the limiting seat are fixedly connected with limiting columns.

[0004] In the actual production of wear-resistant and heat-resistant bending and straight pipes, there is a step of sampling and detecting them, mainly for sampling and detecting the angle of the bending and straight pipes to ensure that the angle of the bending and straight pipes meets the production requirements and ensure the production accuracy of the bending and straight pipe products. In the existing process, the angle sampling and detection structure of the bending and straight pipes generally directly measures the bending angle of the sampled sample with a measuring ruler. However, this measurement method not only requires holding the bending and straight pipe to measure its bending angle, but also requires the inspector to concentrate on observing the angle with the naked eye. If the number of bending and straight pipes sampled by the inspector is large, there will inevitably be certain errors.

[0005] In view of the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0006] In view of the problems in the related technology, the utility model provides a heat-resistant and wear-resistant bending and straight pipe angle sampling detection and measurement device to overcome the above-mentioned technical problems existing in the existing related technology.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model relates to a heat-resistant and wear-resistant bending and straight pipe angle sampling detection device, which comprises a sampling inspection workbench and a bending and straight pipe sample body. An inner part of the front surface of the sampling inspection workbench is provided with a corresponding groove for the bending and straight pipe. The bending and straight pipe sample body is placed inside the corresponding groove for the bending and straight pipe. A scale measuring ruler is connected to the top end of the sampling inspection workbench. The scale measuring ruler is located directly behind the bending and straight pipe sample body. A detection component is arranged on the sampling inspection workbench. The detection component is used for detecting the angle of the bending and straight pipe sample body to ensure the production precision of the bending and straight pipe sample body.

[0009] Further, the detection component comprises two fixing rods, a connecting plate, a limiting detection plate and two contraction springs. The two fixing rods are both arranged inside the sampling inspection workbench. Sliding blocks are slidably connected to the surfaces of the two fixing rods. The connecting plate is arranged between the two sliding blocks. A fixing block is connected to the back surface of the connecting plate. The limiting detection plate is arranged at one end of the fixing block. A handle is connected to the front surface of the connecting plate. The two contraction springs are respectively sleeved on the surfaces of the two fixing rods. Support rods are connected to one ends of the two fixing rods.

[0010] Further, the surfaces of the two sliding blocks are slidably attached to the inner side of the sampling inspection workbench.

[0011] Further, the surface of the limiting detection plate is attached to the surface of the bending and straight pipe sample body.

[0012] Further, one ends of the two support rods are both connected to the front surface of the sampling inspection workbench.

[0013] Further, two ends of the two contraction springs are respectively connected to the inner side of the sampling inspection workbench and the surfaces of the two sliding blocks.

[0014] The utility model has the following beneficial effects:

[0015] 1. If the bending and straight pipe sample body cannot be placed into the corresponding groove for the bending and straight pipe in the utility model, it can be confirmed that the bending and straight pipe sample body does not meet the sampling qualified standard. If the bending and straight pipe sample body can be placed into the corresponding groove for the bending and straight pipe, then the bending and straight pipe sample body meets the preliminary sampling detection standard. The detection component not only facilitates the limiting of the bending and straight pipe sample body to be detected, but also facilitates the confirmation of whether the bending and straight pipe sample body meets the qualified requirements of sampling detection by observing whether the surface of the detection component is attached to the surface of the bending and straight pipe sample body from top to bottom and whether the detection component loosens after contacting the bending and straight pipe sample body.

[0016] 2. In the present utility model, the scale measuring ruler is located directly behind the bent straight pipe sample body. Then, when needed, the upward length of the bent straight pipe sample body can also be compared, and the operation is simple. In this way, through double verification, not only the detection accuracy of sampling inspection is improved, but also the operator does not need to always hold the bent straight pipe sample body to visually confirm it with the naked eye, reducing the fatigue of sampling inspectors in continuously maintaining attention and improving the accuracy of sampling inspection. Similarly, for the next bent straight pipe sample body that needs to be sampled for angle detection, the same operation can be carried out for detection.

[0017] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0030] Please refer to Figures 1-7 As shown, the present utility model is a heat-resistant and wear-resistant bending straight pipe angle sampling inspection and measurement device, including a sampling inspection workbench 1 and a bending straight pipe sample body 5. A bending straight pipe corresponding groove 4 is opened inside the front surface of the sampling inspection workbench 1, and the bending straight pipe sample body 5 is placed inside the bending straight pipe corresponding groove 4. A scale measuring ruler 3 is connected to the top of the sampling inspection workbench 1, and the scale measuring ruler 3 is located directly behind the bending straight pipe sample body 5. A detection component 2 is provided on the sampling inspection workbench 1, and the detection component 2 is used to perform angle detection on the bending straight pipe sample body 5 to ensure the production accuracy of the bending straight pipe sample body 5.

[0031] First, when it is necessary to sample and detect the random bent straight pipe sample body 5, the operator pulls the detection component 2 outwards so that the detection component 2 is separated from the sampling workbench 1. Then, the bent straight pipe sample body 5 is placed into the sampling workbench 1 through the corresponding slot 4 for the bent straight pipe. Note that if the angle of the bent straight pipe sample body 5 initially meets the qualified standard for sampling inspection, then the bent straight pipe sample body 5 can be placed into the corresponding slot 4 for the bent straight pipe. Then, release the detection component 2. Under the action of elastic contraction, the detection component 2 will fit with the surface bending angle of the bent straight pipe sample body 5. Similarly, if there is no gap when observing from top to bottom that the surface of the detection component 2 fits with the surface of the bent straight pipe sample body 5, then it can be confirmed that the bent straight pipe sample body 5 meets the qualified standard for sampling inspection. Similarly, for the next bent straight pipe sample body 5 that needs to be sampled and detected for the angle, the same operation can be performed for detection. After the detection is completed, pull out the detection component 2 outwards as above so that the detection component 2 is separated from the surface of the bent straight pipe sample body 5 to replace the bent straight pipe sample body 5. At the same time, the scale measuring ruler 3 is located directly behind the bent straight pipe sample body 5. Then, the upward length of the bent straight pipe sample body 5 can also be compared when needed. The operation is simple. In this way, through double verification, not only the detection accuracy of sampling inspection is improved, but also the operator does not need to always hold the bent straight pipe sample body 5 to visually confirm the bent straight pipe sample body 5, reducing the fatigue of the sampling inspection personnel in continuously maintaining attention and improving the accuracy of sampling inspection. Similarly, for the next bent straight pipe sample body 5 that needs to be sampled and detected for the angle, the same operation can be performed for detection.

[0032] If the bent straight pipe sample body 5 cannot be placed into the corresponding slot 4 for the bent straight pipe, then it can be confirmed that the bent straight pipe sample body 5 does not meet the qualified standard for sampling inspection. If the bent straight pipe sample body 5 can be placed into the corresponding slot 4 for the bent straight pipe, then the bent straight pipe sample body 5 meets the preliminary sampling inspection standard. The detection component 2 not only facilitates the positioning of the bent straight pipe sample body 5 to be detected, but also conveniently observes whether the surface of the detection component 2 fits with the surface of the bent straight pipe sample body 5 from top to bottom and whether there is looseness after the detection component 2 contacts the bent straight pipe sample body 5 to facilitate the confirmation of whether the bent straight pipe sample body 5 meets the qualified requirements for sampling inspection. At the same time, the scale measuring ruler 3 is located directly behind the bent straight pipe sample body 5. Then, the upward length of the bent straight pipe sample body 5 can also be compared when needed. The operation is simple. In this way, through double verification, not only the detection accuracy of sampling inspection is improved, but also the operator does not need to always hold the bent straight pipe sample body 5 to visually confirm the bent straight pipe sample body 5, reducing the fatigue of the sampling inspection personnel in continuously maintaining attention and improving the accuracy of sampling inspection. Similarly, for the next bent straight pipe sample body 5 that needs to be sampled and detected for the angle, the same operation can be performed for detection.

[0033] In one embodiment, for the above-mentioned detection component 2, the detection component 2 includes two fixed rods 201, a connecting plate 203, a limit detection plate 205 and two contraction springs 207, the two fixed rods 201 are both arranged on the inner side of the sampling workbench 1, the surfaces of the two fixed rods 201 are slidably connected with sliders 202, the connecting plate 203 is arranged between the two sliders 202, the back of the connecting plate 203 is connected with a fixed block 204, the limit detection plate 205 is arranged at one end of the fixed block 204, the front of the connecting plate 203 is connected with a handle 206, the two contraction springs 207 are respectively sleeved on the surfaces of the two fixed rods 201, and one end of the two fixed rods 201 is connected with a support rod 208.

[0034] First, when it is necessary to sample and test the random bent and straight tube sample bodies 5, the operator pulls the handle 206 outward, and then the slider 202, the connecting plate 203, the fixing block 204 and the limit detection plate 205 are moved outward as a whole under the elastic action of the contraction spring 207, until the limit detection plate 205 is pulled out of the sampling inspection workbench 1, and then the bent and straight tube sample bodies 5 are placed into the corresponding grooves 4 of the bent and straight tubes through the gap. Note that if the angle or side is skewed here, the bent and straight tube sample bodies 5 cannot be stuck into the bent and straight tubes. If the angle of the bent straight tube sample body 5 initially meets the qualified standard for random inspection, the bent straight tube sample body 5 can be placed in the bent straight tube corresponding groove 4 and continue the following operations, then release the handle 206. Under the elastic contraction of the two contraction springs 207, the slider 202, the connecting plate 203 and the fixing block 204 will drive the limit detection plate 205 to fit the surface bending angle of the bent straight tube sample body 5. If the limit detection plate 20 If the surface of the limit detection plate 205 fits with the surface of the bent straight tube sample body 5 and there is no gap when observed from top to bottom, then it can be confirmed that the bent straight tube sample body 5 meets the qualified standard of the random inspection. However, if the limit detection plate 205 cannot be completely fitted with the bent straight tube sample body 5, that is, the bending angle of the bent straight tube sample body 5 deviates, then it does not meet the qualified standard of the random inspection. After the inspection is completed, the limit detection plate 205 is pulled outward as above so that the limit detection plate 205 is separated from the surface of the bent straight tube sample body 5, and the bent straight tube sample body 5 can be replaced. At the same time, the scale measuring ruler 3 is located directly behind the curved and straight tube sample body 5, so the upward length of the curved and straight tube sample body 5 can also be compared when needed, and the operation is simple. In this way, the double verification not only improves the detection accuracy of the random inspection, but also does not require the operator to always hold the curved and straight tube sample body 5 to confirm the curved and straight tube sample body 5 with the naked eye, thereby reducing the fatigue of the inspection personnel who need to maintain continuous attention and improving the accuracy of the random inspection. Similarly, the next curved and straight tube sample body 5 that needs to be sampled for angle detection can be inspected by the same operation as above.

[0035] If the bent straight pipe sample body 5 cannot be placed into the corresponding slot 4 of the bent straight pipe, it can be confirmed that the bent straight pipe sample body 5 does not meet the sampling qualification standard. If the bent straight pipe sample body 5 can be placed into the corresponding slot 4 of the bent straight pipe, then the bent straight pipe sample body 5 meets the preliminary sampling detection standard. Through the elastic contraction of the contraction spring 207, it is not only convenient to drive the limit detection plate 205 to limit the bent straight pipe sample body 5 to be detected, but also convenient to observe whether the surface of the limit detection plate 205 fits the surface of the bent straight pipe sample body 5 from top to bottom, and whether the limit detection plate 205 loosens after contacting the bent straight pipe sample body 5, so as to confirm whether the bent straight pipe sample body 5 further meets the qualification requirements of sampling detection. In this way, through double verification, not only the detection accuracy of sampling inspection is improved, but also the operator does not need to always hold the bent straight pipe sample body 5 to visually confirm it with the naked eye, reducing the fatigue of the sampling personnel in maintaining concentration all the time and improving the accuracy of sampling inspection. Similarly, the same operation can be carried out for the next bent straight pipe sample body 5 that needs to be sampled and detected for the angle.

[0036] In one embodiment, for the above-mentioned slider 202, the surfaces of both of the two sliders 202 are slidably attached to the inner side of the sampling inspection workbench 1, so as to conveniently improve the stability of the slider 202 during movement, and further prevent the situation that the slider 202 shakes under the pulling action of the contraction spring 207 and affects the detection accuracy.

[0037] In one embodiment, for the above-mentioned limit detection plate 205, the surface of the limit detection plate 205 fits the surface of the bent straight pipe sample body 5, so as to detect whether the accuracy of the bent straight pipe sample body 5 meets the qualification standard by whether the limit detection plate 205 corresponds to the surface of the bent straight pipe sample body 5.

[0038] In one embodiment, for the above-mentioned support rod 208, one ends of both of the two support rods 208 are connected to the front surface of the sampling inspection workbench 1, so as to improve the stability of the fixed rod 201.

[0039] In one embodiment, for the above-mentioned contraction spring 207, both ends of the two contraction springs 207 are respectively connected to the inner side of the sampling inspection workbench 1 and the surfaces of the two sliders 202, so as to play a contraction role in driving the sliders 202, and then conveniently drive the limit detection plate 205 to fit with the bent straight pipe sample body 5 through the sliders 202 for detection.

[0040] In summary, by means of the above technical solution of the present utility model, when it is necessary to sample and detect the random curved straight pipe sample body 5, the operator pulls the handle 206 outwards. Then, under the elastic action of the contraction spring 207, the slider 202, the connecting plate 203, the fixed block 204 and the limit detection plate 205 are driven to move outwards as a whole until the limit detection plate 205 is pulled out of the inside of the sampling workbench 1. Then, the curved straight pipe sample body 5 is placed into the curved straight pipe corresponding groove 4 through the gap. Note that if there is an inclination in the angle or the side at this place, the curved straight pipe sample body 5 cannot be clamped into the curved straight pipe corresponding groove 4, and it can be confirmed that this curved straight pipe sample body 5 does not meet the qualified standard for sampling detection. If the angle of the curved straight pipe sample body 5 initially meets the qualified standard for sampling inspection, that is, the curved straight pipe sample body 5 can be placed into the curved straight pipe corresponding groove 4 and continue the following operations. Then, release the handle 206. Under the elastic contraction action of the two contraction springs 207, the slider 202, the connecting plate 203 and the fixed block 204 will drive the limit detection plate 205 to fit with the surface bending angle of the curved straight pipe sample body 5. If there is no gap when observing from top to bottom that the surface of the limit detection plate 205 fits with the surface of the curved straight pipe sample body 5, then it can be confirmed that the curved straight pipe sample body 5 meets the qualified standard for sampling inspection. However, if the limit detection plate 205 cannot completely fit with the curved straight pipe sample body 5, that is, if there is a deviation in the bending angle of the curved straight pipe sample body 5, then it does not meet the qualified standard for sampling inspection. After the detection is completed, pull out the limit detection plate 205 outwards as above so that the limit detection plate 205 is separated from the surface of the curved straight pipe sample body 5, and the curved straight pipe sample body 5 can be replaced. At the same time, the scale measuring ruler 3 is located directly behind the curved straight pipe sample body 5, so the upward length of the curved straight pipe sample body 5 can also be compared when needed. The operation is simple. In this way, through double verification, not only the detection accuracy of sampling inspection is improved, but also the operator does not need to always hold the curved straight pipe sample body 5 to visually confirm the curved straight pipe sample body 5, reducing the fatigue of the sampling personnel in continuously maintaining attention and improving the accuracy of sampling inspection. Similarly, the same operation can be performed on the next curved straight pipe sample body 5 that needs to be sampled and detected for the angle.

[0041] Through the above technical solution, first, if the bent straight pipe sample body 5 cannot be placed into the corresponding groove 4 of the bent straight pipe, it can be confirmed that the bent straight pipe sample body 5 does not meet the sampling qualification standard. If the bent straight pipe sample body 5 can be placed into the corresponding groove 4 of the bent straight pipe, then the bent straight pipe sample body 5 meets the preliminary sampling detection standard. Through the elastic contraction of the contraction spring 207, it is not only convenient to drive the limit detection plate 205 to limit the bent straight pipe sample body 5 to be detected, but also convenient to observe whether the surface of the limit detection plate 205 fits with the bent straight pipe sample body 5 from top to bottom and whether the limit detection plate 205 loosens after contacting the bent straight pipe sample body 5, so as to confirm whether the bent straight pipe sample body 5 further meets the qualified requirements of sampling detection. At the same time, the scale measuring ruler 3 is located directly behind the bent straight pipe sample body 5, so the upward length of the bent straight pipe sample body 5 can also be compared when needed. The operation is simple. In this way, through double verification, not only the detection accuracy of sampling inspection is improved, but also the operator does not need to always hold the bent straight pipe sample body 5 to visually confirm the bent straight pipe sample body 5, reducing the fatigue of the sampling inspection personnel in continuously maintaining attention and improving the accuracy of sampling inspection. Similarly, the same operation can be performed on the next bent straight pipe sample body 5 that needs to be sampled for angle detection.
