[0027] Example 1

[0028] The preferred embodiment of the metal pipe hydraulic press protection device provided by the utility model is as follows Figures 1 to 6 As shown: a metal pipe hydraulic press protective device, including a base 1, a water pool 2 is fixedly connected to the top of the base 1, both ends of the water pool 2 are provided with assembly plates 3 fixedly connected to the base 1, and the insides of the two sets of assembly plates 3 are provided with card slots 4, a hydraulic press body 9 fixedly connected to the base 1 is provided on one side of the water pool 2, a first hydraulic push rod 5 is fixedly connected to the left side of the hydraulic press body 9, and the output end of the first hydraulic push rod 5 is fixedly connected to a card plate 6 embedded in the card slot 4, a protective plate 7 is slidably connected to the inside of the assembly plate 3, and a sticking film 8 is pasted on the surface of the protective plate 7, and a metal pipe is connected to the right side of the hydraulic press body 9. The base 10 has two sets of second hydraulic push rods 11 fixedly connected to the top, the output ends of the two sets of second hydraulic push rods 11 are fixedly connected to mounting plates 12, one ends of the two sets of mounting plates 12 are rotatably connected to connecting shafts 13, the tops of the two sets of connecting shafts 13 are fixedly connected to transmission plates 14, both sides of the two sets of transmission plates 14 are fixedly connected to first springs 15, the tails of the two sets of connecting shafts 13 are fixedly connected to connecting plates 16, one side of the two sets of connecting plates 16 are fixedly connected to third electric push rods 17, and the output ends of the two sets of third electric push rods 17 are fixedly connected to clamp rings 18 that fit tightly with the metal tube body 10.

[0029] In this embodiment, the assembly plate 3 is a "U"-shaped structure, and the protective plate 7 is in close contact with the inner wall of the assembly plate 3, which can avoid a gap between the protective plate 7 and the assembly plate 3 and cause the assembly plate 3 to loosen.

[0030] In this embodiment, the left side of the protective plate 7 is in contact with the clamping plate 6, and the protective plate 7 is fixed inside the assembly plate 3 through the clamping plate 6. When replacing the protective plate 7, the clamping plate 6 is pulled upward by the first hydraulic push rod 5, and finally the protective plate 7 is pulled out from the inside of the assembly plate 3.

[0031] In this embodiment, the connecting plate 16 is disposed at the center of the connecting shaft 13, and the third electric push rod 17 drives the clamping ring 18 to form a clamping structure, which can prevent the metal pipe body 10 from being loosened from the hydraulic press body 9 during inspection.

[0032] Example 2

[0033] Based on Example 1, a preferred embodiment of a metal pipe hydraulic press protection device provided by the utility model is as follows: Figures 1 to 6As shown: a support plate 24 is fixedly connected to the top of the hydraulic press body 9, a motor 19 is fixedly connected to the top of the support plate 24, a rotating plate 20 is fixedly connected to the output end of the motor 19, a push plate 21 slidably connected to the support plate 24 is provided on one side of the rotating plate 20, a second spring 22 located at one end of the transmission plate 14 is fixedly connected to one side of the push plate 21, and a fan 23 is fixedly connected to the inner wall of the support plate 24.

[0034] In this embodiment, the push plate 21 is located on the rotation trajectory of the rotating plate 20. The push plate 21 forms a sliding structure along the top of the support plate 24 through the rotating plate 20. The motor 19 is turned on to control the rotation of the rotating plate 20. When the rotating plate 20 rotates, it pushes the push plate 21, causing the push plate 21 to move toward the transmission plate 14.

[0035] In this embodiment, the transmission plate 14 is located on the sliding track of the push plate 21. The transmission plate 14 forms a rotating structure through the push plate 21. When the push plate 21 continues to move, it will apply thrust to the transmission plate 14, so that the transmission plate 14 drives the connecting shaft 13 to rotate clockwise around the connection with the mounting plate 12.

[0036] In this embodiment, the air outlet of the fan 23 is set at a 45° tilt, and the metal tube body 10 will rotate to a tilted state and correspond to the fan 23. At this time, the fan 23 will blow out wind to make the water stains inside the metal tube body 10 flow out along the inclined surface of the inner wall of the metal tube body 10, thereby preventing the water stains from causing rust inside the metal tube body 10.

[0037] The working principle and use process of the utility model are as follows: first, the metal pipe body 10 to be inspected is placed between the two groups of clamp rings 18, and the clamp ring 18 is pushed by the third electric push rod 17 to clamp and fix the metal pipe body 10, then, the second hydraulic push rod 11 is opened to control the mounting plate 12 to approach the hydraulic press body 9, at which time the metal pipe body 10 will be embedded into the interior of the hydraulic press body 9, and then the metal pipe body 10 can be inspected by the hydraulic press body 9. During the inspection process, in order to prevent the high-speed pipe segments from splashing and scratching others after the metal pipe body 10 bursts, the splashing fragments can be effectively blocked under the action of the protective plate 7, and the surface of the protective plate 7 is pasted with an adhesive film 8, so even if the protective plate 7 is broken by debris, under the action of the adhesive film 8, the debris of the protective plate 7 will not splash, and the protective plate 7 is fixed to the assembly plate 3 through the card plate 6. When replacing the protective plate 7, the card plate 6 is pulled upward by the first hydraulic push rod 5, and finally the protective plate 7 can be pulled out from the inside of the assembly plate 3;

[0038] After the metal pipe body 10 is inspected, in order to avoid rust caused by water stains inside, the metal pipe body 10 can be pulled out from the hydraulic press body 9 by the second hydraulic push rod 11, and the motor 19 is turned on to control the rotating plate 20 to rotate. When the rotating plate 20 rotates, it pushes the push plate 21, so that the push plate 21 moves toward the transmission plate 14. When the push plate 21 keeps moving, it applies thrust to the transmission plate 14, so that the transmission plate 14 drives the connecting shaft 13 to rotate clockwise around the connection with the mounting plate 12, and the connecting plate 1 Then, the clamp ring 18 is driven to rotate by the third electric push rod 17, and the metal tube body 10 clamped by the clamp ring 18 is controlled to rotate. At this time, the metal tube body 10 rotates to an inclined state and corresponds to the fan 23. At this time, the fan 23 blows out wind to make the water stains inside the metal tube body 10 flow out along the inclined surface of the inner wall of the metal tube body 10 to prevent the water stains from causing rust inside the metal tube body 10. When the push plate 21 no longer pushes the transmission plate 14, the transmission plate 14 is adjusted to a vertical state under the action of the first spring 15.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
