Description

Technical Field

[0001] The present application relates to secondary water supply equipment, and in particular to a detection device for a flood-proof pump barrel. Background Art

[0002] Secondary water supply equipment is often found in medium and high-rise buildings in cities. It is used to boost the municipal water supply to meet the water needs of users on high floors. The water pump is one of the core components of the secondary water supply equipment. It is used to transfer the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. CN209925232U provides a vertical submersible pump, which is composed of two sections of pump barrels. The pump barrel includes a circular tube shell and flanges located at both ends of the circular tube shell. Therefore, this type of pump barrel often needs to be fully welded during the actual processing and manufacturing process so that the flange is sealed and fixed to the end of the circular tube shell. Due to the thermal deformation problem in the welding process, it is easy to cause the two ends of the same section of the pump barrel to be eccentric or deformed and twisted, or it may cause the upper and lower sections of the pump barrel to be unable to dock smoothly when connected. Utility Model Content

[0003] In order to solve the technical problems of thermal deformation, distortion or concentricity deviation of pump barrels caused by welding in the prior art, the present application provides a detection device for anti-flooding pump barrels, which has at least the advantages of convenient detection and high measurement accuracy.

[0004] The present application provides a detection device for a flood-proof pump barrel, comprising: a workbench, the workbench comprising a work surface, a slide rail mechanism disposed on both sides of the work surface, and a pump barrel bracket fixed at the middle of the work surface and located between the two slide rail mechanisms; detection fixtures are disposed on both sides of the pump barrel bracket, and the detection fixtures are slidably connected to the slide rail mechanism; the detection fixture comprises a vertically arranged fixing part, a circular ring part disposed on the fixing part and facing the pump barrel bracket, and a go / no-go gauge disposed on the fixing part and distributed on the outer circumference of the circular ring part; the outer wall of the circular ring part is adapted to the inner wall of the flange at the end of the pump barrel, and the height of the circular ring part is adapted to the depth of the flange; the go / no-go gauge is adapted to the threaded hole of the flange.

[0005] Specifically, one of the concepts of the present application is to detect the welding distortion of the flanges at both ends of the pump barrel by setting up detection tools at both ends of the pump barrel bracket, and to synchronously detect the threaded holes of each flange, thereby improving the detection efficiency and detection accuracy.

[0006] Furthermore, the detection device for flood prevention pump barrel includes: a grating micrometer; the grating micrometer is connected to the fixing part.

[0007] Specifically, another concept of the present application is to synchronously detect the concentricity of the pump barrel through the grating micrometer, so as to achieve higher detection accuracy and better detection timeliness.

[0008] Furthermore, the grating micrometer has the freedom to move along the direction of the pump barrel bracket and along the direction in which the pump barrel is placed.

[0009] Specifically, by adjusting the grating micrometer, the grating micrometer can measure the multi-point concentricity of the flange and the multi-point concentricity of the circular tube shell.

[0010] Furthermore, the grating micrometer is preset with concentricity judgment parameters and includes an alarm.

[0011] Specifically, the concentricity of the pump barrel is directly judged according to the concentricity judgment parameters. When the concentricity of the pump barrel does not meet the concentricity judgment parameters, it is judged as a defective product, and an alarm is used to improve the intelligence level of detection.

[0012] In some embodiments, the work surface is a square frame constructed of tool steel, and the frame structure is used to reduce the manufacturing cost of the workbench.

[0013] Furthermore, the pump barrel bracket includes at least two groups of support seats; the support seat includes two V-shaped support plates and two rolling wheels sandwiched between the two V-shaped support plates and symmetrical along the central axis of the V-shaped support plates.

[0014] Specifically, the rolling wheel with rolling freedom can avoid scratching the outer surface of the pump barrel and has good positioning accuracy.

[0015] Furthermore, the slide rail mechanism includes a rail and a slider that cooperates with the slide rail.

[0016] Furthermore, the slide rail mechanism includes a driving block for driving the sliding block.

[0017] Furthermore, the slide rail mechanism includes a force feedback device and an alarm connected to the force feedback device.

[0018] Specifically, after the detection tooling enters the flange, or when the flange is abnormally deformed, the force feedback device can control the slider to stop in time to avoid collision between the two and cause losses.

[0019] In some embodiments, the fixing member includes an isosceles triangle plate and a circular ring plate which is overlapped and connected with the isosceles triangle plate and has a diameter greater than the waist height of the isosceles triangle plate; the inner diameter of the circular ring plate is adapted to the outer diameter of the circular ring member; the isosceles triangle plate is connected to the slider via two isosceles angles respectively.

[0020] Specifically, the use of the isosceles triangle plate in conjunction with the annular plate can effectively improve the connection stability of the detection tooling and reduce its own weight.

[0021] In summary, the present application provides a detection device for a flood prevention pump barrel, which has at least the following advantages:

[0022] 1. Through the detection fixtures arranged at both ends of the pump barrel bracket, the welding distortion of the flanges at both ends of the pump barrel is detected, and the threaded holes of each flange are synchronously detected at the same time, thereby improving the detection efficiency and detection accuracy;

[0023] 2. The concentricity of the pump barrel is synchronously detected by the grating micrometer, so that the detection accuracy is higher and the detection timeliness is better;

[0024] 3. The concentricity of the pump barrel is directly judged according to the concentricity judgment parameters. When the concentricity of the pump barrel does not meet the concentricity judgment parameters, it is judged as a defective product and an alarm is used to improve the intelligent level of detection;

[0025] 4. Through the frame structure and structural design, the overall weight of the device is reduced, making the cost of the device lower. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figure 1 and2 , a detailed description of this application is given.

[0031] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] It is worth noting that the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, a conflicting connection, or an integral connection; wherein, "connection" can also be a direct connection or an indirect connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. For example, the detection fixture 14 is slidably connected to the slide rail mechanism 12, and combined with the context, it is understood that the detection fixture 14 can slide back and forth on the slide rail mechanism 12.

[0033] See also Figure 1 Shown is a schematic structural diagram of a detection device for a flood prevention pump barrel 2 provided in an embodiment of the present application.

[0034] Specifically, the workbench 1 is a frame body constructed of tool steel, and the working surface 11 is a square frame constructed of tool steel. The slide rail mechanism 12 is placed on the tool steel on both sides of the working surface 11, and is used to realize the sliding of the detection fixture 14 slidably connected to the slide rail mechanism 12. The pump barrel bracket 13 is placed between the two detection fixtures 14, and the fixing part 141 of the detection fixture 14 is vertically arranged on the slide rail mechanism 12, and faces the pump barrel bracket 13 through the circular ring 142 and the go / no-go gauge 143 connected to the fixing part 141. The pump barrel 2 is placed between the pump barrels 2, so that the flanges 22 at both ends of the pump barrel 2 face the detection fixture 14 facing them respectively. The outer wall of the circular ring 142 is adapted to the inner wall of the flange 22, and the height of the circular ring 142 is adapted to the depth of the flange 22; the go / no-go gauge 143 is adapted to the threaded hole of the flange 22. It is worth explaining that adaptation means mutual cooperation. For example, the outer wall of the circular ring 142 is adapted to the inner wall of the flange 22, which specifically means that the two are clearance-fitted and have matching accuracy. The go / no-go gauge 143 is adapted to the threaded hole of the flange 22, which also means that the two are clearance-fitted. The go / no-go gauge 143 is a standard part used to detect whether the threaded hole meets the specified requirements.

[0035] Therefore, the working principle of the present application is: place the pump barrel 2 on the pump barrel bracket 13, and then push the detection fixture 14 at both ends, and under the action of the slide rail mechanism 12, move toward the flange 22 of the pump barrel 2, and engage with the flange 22 and its threaded hole through the circular ring 142 and the go / no-go gauge 143 of the detection fixture 14. When the inspection tool 14 on one side can be engaged with the flange 22, but the inspection tool 14 on the other side cannot be engaged, it means that the pump barrel 2 has bent and deformed after the welding of the flanges 22 on both sides is completed; when the circular ring 142 cannot be engaged with the flange 22, the concentricity of the flange 22 does not meet the use requirements, or when the circular ring 142 cannot be completely engaged with the flange 22, the installation depth of the flange 22 cannot meet the use requirements; when the go / no-go gauge 143 cannot be engaged with the threaded hole, the threaded hole cannot meet the use requirements; only when the inspection tool 14 on both sides can be completely engaged with the flange 22, and the go / no-go gauge 143 is engaged with the threaded hole, the pump barrel 2 is qualified and can flow into the next process for use.

[0036] Furthermore, the grating micrometer 15 is connected to the fixing part 141 and faces the pump barrel bracket 13. When the detection fixtures 14 at both ends are fully engaged with the flange 22, the grating micrometer 15 is adjusted along the direction in which the pump barrel 2 is placed and along the direction of the pump barrel bracket 13, and the concentricity of multiple points on the inner wall of the flange 22 and the concentricity of multiple points on the inner wall of the circular tube shell 21 are detected respectively, thereby completing the measurement of the concentricity of the pump barrel 2, and further providing the detection accuracy and reliability of the concentricity of the pump barrel 2.

[0037] Furthermore, the grating micrometer 15 is preset with concentricity judgment parameters and includes an alarm. When the concentricity of the pump barrel 2 does not meet the concentricity judgment parameters, it is judged as a defective product and an alarm is used to improve the intelligent level of detection.

[0038] Furthermore, the slide rail mechanism 12 includes a rail 121 and a slider 122 that cooperates with the slide rail.

[0039] Furthermore, the slide rail mechanism 12 includes a driving block for driving the slider 122 .

[0040] Furthermore, the slide rail mechanism 12 includes a force feedback device and an alarm connected to the force feedback device.

[0041] Specifically, after the detection tool 14 enters the flange 22, or when the flange 22 is abnormally deformed, the force feedback device can control the slider 122 to stop in time to avoid losses.

[0042] In some embodiments, the fixing member 141 includes an isosceles triangle plate 1411 and a circular ring plate 1412 which is overlapped and connected with the isosceles triangle plate 1411 and has a diameter greater than the waist height of the isosceles triangle plate 1411; the inner diameter of the circular ring plate 1412 is adapted to the outer diameter of the circular ring member 142; the isosceles triangle plate 1411 is connected to the slider 122 through two isosceles angles. The use of the isosceles triangle plate 1411 in conjunction with the circular ring plate 1412 can effectively improve the connection stability of the detection tooling 14 and reduce its own weight.

[0043] See also Figure 2 Shown is a schematic structural diagram of the support base 131 provided in an embodiment of the present application.

[0044] Specifically, the support seat 131 includes two V-shaped support plates 1311 and two rolling wheels 1312 clamped between the two V-shaped support plates 1311 and symmetrical along the central axis of the V-shaped support plates 1311. When the pump barrel 2 is placed between the two rolling wheels 1312, it can roll under the action of the rolling wheels 1312 to inspect the appearance of its outer surface.

[0045] The present application is described in detail above. Specific examples are used in the present application to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the present application and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
