Description

Technical Field

[0001] This utility model relates to the field of modular shelters, specifically to a modular shelter sealing test device. Background Technology

[0002] Containerized shelters are commonly used in the transportation of large cargo. For cargo with excessively long axial distances, containerized shelters are usually constructed by splicing sections together, with the cargo running through each section. Each section of the container has an open end, and a sealing ring needs to be installed between the open end and the cargo to ensure good sealing of the cargo within that section of the container, maintaining a constant temperature. The sealing ring also acts as a buffer, as the cargo compresses against the sealing ring during transportation, preventing the cargo from colliding with the shelter walls when the vehicle is bumpy.

[0003] The open end of the open container needs to undergo rigorous simulation tests. The existing technology is to seal the open end with a simulated part that is similar in shape to the cargo and then conduct high and low temperature tests. However, the simulated part itself does not have power and cannot be adjusted. It is simply placed inside the container and cannot control the direction and force of the compression on the sealing ring. Therefore, it is impossible to test the sealing and buffering effect of the sealing ring. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the existing technology and to propose a container sealing test device.

[0005] The solution is a container sealing test device, characterized in that it includes a sealing plate, a base frame, a horizontal adjustment mechanism, and a vertical adjustment mechanism.

[0028] 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.

[0029] Before leaving the factory, the modular container undergoes rigorous performance testing to ensure product quality. To guarantee the thermal insulation and sealing performance of the open modular container, a modular container sealing test device is designed during the container testing phase, which is fixed to the test platform along with the modular container during the sealing test. The device simulates the cargo loading state of the modular container by autonomously adjusting the compression of the sealing ring by the sealing disc.

[0030] like Figures 1 to 7 As shown, a container sealing test device includes a sealing disc 10, a base frame 40, a horizontal adjustment mechanism 20, and a vertical adjustment mechanism 30. The sealing disc 10 simulates the shape of an object loaded in a container, and a wing plate 11 is fixedly mounted on one side of the sealing disc 10. The base frame 40 is fixedly mounted on a test platform. The horizontal adjustment mechanism 20 clamps the wing plate 11 and is configured to drive the sealing disc 10 to move horizontally. The clamping mechanism between the sealing disc 10 and the horizontal adjustment mechanism 20 is detachable for easy replacement of the sealing disc 10. The horizontal adjustment mechanism 20 is mounted on the vertical adjustment mechanism 30, which is mounted on the base frame 40. The vertical adjustment mechanism 30 is configured to drive both the horizontal adjustment mechanism 20 and the wing plate 11 to move vertically simultaneously. The horizontal adjustment mechanism 20 and the vertical adjustment mechanism 30 work together to achieve multi-angle compression requirements.

[0031] The sealing disc 10 has a similar shape to the open end of the cabin 5; the sealing disc 10 is filled with insulation material and has a welded outer skin. The shape of the sealing disc 10 is consistent with the cross-sectional shape of the cargo at the open end of the cabin 5, and the sealing ring 6 is installed inside the open port of the cabin 1; the insulation material is preferably rock wool or polyurethane foam board. After the sealing disc 10 is placed in the port of the cabin 5, the insulation material and the outer skin effectively maintain a constant internal temperature of the cabin 5, ensuring accurate high and low temperature test results.

[0032] The horizontal adjustment mechanism 20 includes a track platform 27, with a sliding platform 25 slidably connected above the track platform 27. A threaded through hole 26 is formed inside the sliding platform 25, and the threaded through hole 26 is in the same direction as the sliding platform 25. A first screw 22 is threadedly connected to the threaded through hole 26, with one end of the first screw 22 extending out of the threaded through hole 26 and rotatably connected to the track platform 27. Because the sliding platform 25 is slidably connected to the track platform 27, during the rotation of the first screw 22, the sliding platform 25 is restricted to horizontal movement by the track platform 27, while the first screw 22 can only rotate under the restriction of the track platform 27. This achieves the function of controlling the left and right displacement of the sliding platform 25 by rotating the first screw 22.

[0033] Two first fixed seats 8 are symmetrically arranged on the sliding platform 25. The first fixed seats 8 are threaded with horizontally arranged fixing bolts 7, and the two fixing bolts 7 are arranged opposite each other. There are two wing plates 11, which are symmetrically arranged between the two first fixed seats 8. The two wing plates 11 are provided with through holes. The fixing bolts 7 pass through the through holes of adjacent wing plates 11 and are threaded with nuts 9. The two nuts serve to clamp the wing plates 11. By adjusting the position of the nuts 9, the horizontal position of the sealing disc 10 can be finely adjusted, thereby enabling the sealing ring 6 on the compressed side to achieve the target compression amount.

[0034] like Figure 6 As shown, a second fixed seat 21 protrudes upward from one end of the track platform 27. A groove is formed on the second fixed seat 21, with the upper end of the groove open. A limiting ring 24 is fixedly fitted onto one end of the first screw 22 extending from the sliding platform 25. The limiting ring 24 is slidably connected to the groove. The first screw 22 extends out of the second fixed seat 21 and is fixedly connected to the horizontal adjustment knob 23. The groove restricts the axial movement of the limiting ring 24, thus restricting the axial movement of the first screw 22, so that the first screw 22 can only rotate when the horizontal adjustment knob 23 is rotated. During installation, first, the first screw 22 is placed into the groove of the second fixed seat 21, then the sliding platform 25 is slidably connected to the track platform 27. Rotating the horizontal adjustment knob 23 causes the first screw 22 to screw into the threaded through hole 26, completing the installation of the horizontal adjustment mechanism 20.

[0035] The vertical adjustment mechanism 30 includes guide sleeves 31 fixed at both ends below the track platform 27. Guide sleeves 31 are slidably connected to guide posts 32, and the lower ends of guide posts 32 are fixed to the base frame 40. The vertical adjustment mechanism 30 also includes a nut post 33 fixed directly below the track platform 27. The nut post 33 is threadedly connected to a second screw 34, and the lower end of the second screw 34 is rotatably connected to a third fixed seat 35, which is fixedly connected to the base frame 40. Due to the constraints of the two guide posts 32 and the guide sleeves 31, rotating the second screw 34 can drive the nut post 33 to move up and down.

[0036] like Figure 7 As shown, the second screw 34 extends into the third fixed seat 35. The lower end of the second screw 34 is also provided with a shoulder, and a threaded cover 36 is fitted above the shoulder. The threaded cover 36 is threadedly connected to the third fixed seat 35, pressing the shoulder into the threaded cover 36. A vertical adjustment knob 37 is provided on the second screw 34, located above the threaded cover 36. The second screw 34 rotates within the third fixed seat 35. The threaded cover 36 prevents the second screw 34 from dislodging from the third fixed seat 35. When installing the vertical adjustment mechanism 30, first, the threaded cover 36 is fitted onto the second screw 34, then the second screw 34 is screwed into the nut post 33, the two guide sleeves 31 are fitted onto the guide post 32, and finally, the threaded cover 36 is tightened onto the third fixed seat 35.

[0037] The track platform 27 has a horizontal scale 28, and the wing plate 11 has a slot that is engaged with the sliding platform 25; the guide column 32 has a vertical scale 38. The scale lines help the operator control the degree of compression of the sealing ring and also facilitate reset after the test; when the two wing plates 11 are symmetrical about the horizontal scale 28, the sealing disc 10 is in a horizontally centered position.

[0038] The base frame 40 includes fixed beams 41, vertical beams 42, diagonal beams 43, and a first horizontal beam 44. There are two fixed beams 41 spaced apart, each with connecting holes for fixed installation on the test platform. Depending on the test environment and the specific structure of the container, the container may be placed directly on the platform or fixed to a bracket during testing. Therefore, the connecting holes of the fixed beams 41 can be located on the side or top to accommodate different test methods. The vertical beams 42 are perpendicularly connected to the fixed beams 41. The diagonal beams 43 are diagonally connected between the fixed beams 41 and the vertical beams 42 to strengthen the base frame 40. The first horizontal beam 44 is fixed between the two vertical beams 42. A guide column 32 is fixed to either the vertical beam 42 or the first horizontal beam 44, and a third fixing seat 35 is fixed to the first horizontal beam 44. To enhance the stability of the base frame 40, it is not limited to adding connecting beams between the two fixed beams 41.

[0039] When using this test apparatus, the container 1 is hoisted and placed on the test platform. First, the wing plate 11 of the sealing disc 10 is fixed on the horizontal adjustment mechanism 20 so that the sealing disc 10 is located at the center of the open end of the container 1. Then, the fixed base frame 40 is fixed on the test platform. The position of the sealing disc 10 is adjusted by the vertical adjustment mechanism 30 and the horizontal adjustment mechanism 20 so that the sealing disc 10 squeezes the sealing ring 6 to verify the sealing, heat preservation, and buffering performance of the container 1. After the current product test is completed, the position of the sealing disc 10 is centered and adjusted by the vertical adjustment mechanism 30 and the horizontal adjustment mechanism 20. Then, the next identical product is hoisted and placed in the same position for another test.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
