Description

Technical Field

[0001] This utility model relates to the field of pressure resistance testing technology, specifically a pressure resistance testing device for mechanical and electrical equipment. Background Technology

[0002] Electrical equipment is a general term for equipment such as generators, transformers, power lines, and circuit breakers in a power system. The compressive strength of the electrical equipment casing plays a crucial role in ensuring the safe and stable operation of the equipment and extending its service life. Therefore, it is necessary to conduct compressive strength testing on the casing to prevent equipment failure caused by deformation or damage of the casing due to external forces, thereby reducing the service life of the equipment.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN219870771U) discloses a pressure resistance testing device for mechanical and electrical equipment. The device includes a support base, a cylinder, a pressure block, an electric push rod, a push plate, and a collection box. The cylinder is mounted on the top of the support base, and the bottom end of the cylinder's telescopic rod is connected to the pressure block via a coupling. An electric push rod is mounted on the rear side of the support base, and a push plate is fixedly connected to the front end of the electric push rod's output shaft. The push plate is located inside the support base, and a collection box is slidably mounted on the bottom of the support base. By installing a protective plate, the device can prevent fragments of crushed electrical equipment from being ejected. Activating the electric push rod moves the push plate forward, pushing the mechanical parts on the support base into the collection box in one go, thus facilitating the collection of the mechanical parts.

[0004] While the aforementioned patent can collect fragments through a collection box, it has limitations in the pressure resistance testing of electrical equipment housings. It can only perform pressure resistance testing in a single direction. If pressure resistance testing is performed on different sides of the electrical equipment housing, it is necessary to manually adjust it continuously. This increases the number of operation steps and causes the device to repeatedly perform clamping, positioning, pressure testing, and loosening unloading, thereby increasing the overall time of pressure resistance testing of electrical equipment housings and reducing the working efficiency of the equipment.

[0005] Therefore, this utility model provides a pressure testing device for mechanical and electrical equipment to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-5As shown, this utility model provides a pressure testing device for mechanical and electrical equipment, including a support leg 1, a workbench 11 fixedly connected to the top of the support leg 1, a column 12 fixedly connected to the lower surface of the workbench 11, and a bearing plate 13 fixedly connected to the lower surface of the column 12; a lifting assembly 2, which is disposed above the bearing plate 13 and is used for lifting and supporting the electrical equipment; and a support frame 3, which is fixedly connected to the upper surface of the workbench 11, and a set of clamping assemblies 4 are provided on all four sides of the support frame 3. The symmetrical clamping assemblies 4 are used for clamping, positioning, and angle rotation adjustment of the electrical equipment. Through this structure, when the device performs pressure testing on the housing of the electrical equipment, the rotation adjustment of the housing of the electrical equipment can be achieved by clamping and rotating the clamping assemblies 4, thus eliminating the need for manual adjustment and realizing pressure testing of the housing of the electrical equipment in different positions, greatly improving the efficiency of the device.

[0019] Furthermore, both the workbench 11 and the support frame 3 have a circular hole at their center. The lifting assembly 2 includes a first cylinder 21, which is fixedly connected to the upper surface of the bearing plate 13. The lifting end of the first cylinder 21 is fixedly connected to a support plate 22, which is located inside the circular hole. The support plate 22 is used to place electrical equipment. By controlling the lifting of the first cylinder 21, the support plate 22 can be adjusted up and down to place the electrical equipment housing. At the same time, by adjusting the support height of the electrical equipment housing, it is ensured that the sides of electrical equipment housings of different sizes are precisely aligned with the clamping plate 45, and that the clamping plate 45 clamps the sides of the equipment in a centered manner.

[0020] Furthermore, a guide plate 14 is fixedly connected to the outer wall of the column 12, and four guide shafts 23 are circumferentially distributed on the lower surface of the support plate 22. The guide shafts 23 slide through to the bottom of the guide plate 14. Through the sliding connection between the guide shafts 23 and the guide plate 14, the support plate 22 is assisted in guiding, ensuring the stability of the vertical displacement of the support plate 22.

[0021] Furthermore, two sets of support rods 5 are symmetrically distributed on the upper surface of the workbench 11. A crossbar 51 is fixedly connected between the two sets of support rods 5, and a third cylinder 52 is fixedly connected to the upper surface of the crossbar 51. The lifting end of the third cylinder 52 extends through to the bottom of the crossbar 51 and is connected to a pressure plate. The pressure plate and the bearing plate 13 are coaxially distributed. By driving the pressure plate down through the third cylinder 52, the pressure resistance test of the electrical equipment housing can be realized. By applying different forces, it can be observed whether the shape of the electrical equipment housing changes.

[0022] Furthermore, each side of the support frame 3 is integrally formed with a bearing sleeve 31 and a motor frame 32. The bearing sleeve 31 and the motor frame 32 are vertically distributed and located at the center line of each side of the support frame 3. The clamping assembly 4 includes a servo motor 41, which is fixedly connected to the outer wall of the motor frame 32. A gear 42 is fixedly connected to the output end of the servo motor 41. A gear ring 43 meshes with the outside of the gear 42. A second cylinder 44 is fixedly connected to the center of the gear ring 43, and one end of the second cylinder 44 is rotatably connected to the inside of the bearing sleeve 31. A clamping plate 45 is fixedly connected to the lifting end of the second cylinder 44. The lifting of the second cylinder 44 drives the clamping assembly 45. The clamping plate 45 can be displaced to clamp the side of the electrical equipment housing. The left and right clamping components 4 form one group, and the front and rear clamping components 4 form another group, which can realize the rotation adjustment of the electrical equipment housing in different positions. When each group of clamping components 4 is rotated, the other group of clamping components 4 and the lifting component 2 release the clamping and support of the electrical equipment housing to avoid restricting its rotation adjustment. Driven by the servo motor 41, the gear 42 is driven to rotate. The meshing of the gear ring 43 and the gear 42 drives the second cylinder 44 to rotate. The clamping and positioning of the electrical equipment housing by the clamping plate 45 can realize the angle rotation adjustment.

[0023] Working principle: First, the electrical equipment housing is placed on top of the support plate 22. The support height is then adjusted according to its dimensions to align the center of its side with the clamping plate 45. The second cylinder 44 pushes the clamping plate 45 to clamp and position the side of the electrical equipment housing. The third cylinder 52 then drives the pressure plate downwards, achieving pressure testing of the electrical equipment housing. Simultaneously, the individual operation of each clamping assembly 4 allows for angle adjustment of the electrical equipment housing. When the second cylinders 44 on both sides rotate, the front and rear clamping assemblies 4 release their clamps. The left and right servo motors 41 drive the gears 42 to rotate. With the gear ring 43 meshing with the gear 42, the gear ring 43 drives the second cylinder 44 to rotate, thus achieving rotation adjustment of the electrical equipment housing. After adjustment, the support plate 22 is raised and lowered to support the bottom of the electrical equipment housing, allowing for another pressure test.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
