Description

Technical Field

[0001] This utility model relates to test chamber equipment, and in particular to a large test chamber support base plate. Background Technology

[0002] In the use of various large-scale test chambers, such as material test chambers and environmental simulation test chambers, the base plate is a key component that supports the entire test chamber and the test objects inside. During test chamber testing, some products are very large, weighing over 15 tons. In such cases, a product transfer vehicle is needed to carry the product and move it into the test chamber for testing.

[0003] Traditional load-bearing base plates often lack the structural strength required for large test chambers under high-load testing conditions. In some tests with extremely high load-bearing capacity requirements, the base plate may deform or even be damaged due to excessive force. Utility Model Content

[0004] This utility model provides a large test chamber bearing base plate, which aims to solve the problem that the structural strength of traditional bearing base plates is often insufficient to meet the requirements of large test chambers under high load test conditions. In some tests with extremely high load-bearing capacity requirements, the base plate may deform or even be damaged due to excessive force.

[0005] This utility model is implemented as follows: a large test chamber bearing base plate includes a base plate, on which two sets of reinforcing structures are symmetrically arranged. The reinforcing structures include: reinforcing ribs, with an H-shaped steel symmetrically arranged at both ends of the reinforcing ribs, an upper reinforcing steel plate fixedly connected to the top of the reinforcing ribs, and a lower reinforcing steel plate fixedly connected to the bottom of the reinforcing ribs.

[0006] Preferably, the reinforcing ribs are fixed to the H-beams at both ends, as well as the upper and lower reinforcing steel plates, by welding, with a welding point spacing of 300-400mm.

[0007] The advantages of adopting the above-mentioned further solutions are: ensuring structural stability, intermittent welding, ensuring connection strength, reducing deformation, and avoiding stress concentration.

[0008] Preferably, the upper reinforcing steel plate is welded to the top of the H-beams at both ends, and the distance between the welding points is no more than 200mm.

[0009] The advantages of adopting the above-mentioned further solutions are: ensuring structural stability, intermittent welding, ensuring connection strength, reducing deformation, and avoiding stress concentration.

[0010] Preferably, the lower reinforcing steel plate is welded to the bottom of the H-beams at both ends, and the distance between the welding points is no more than 500mm.

[0011] The advantages of adopting the above-mentioned further solutions are: ensuring structural stability, intermittent welding, ensuring connection strength, reducing deformation, and avoiding stress concentration.

[0012] Preferably, an epoxy fiberglass board is provided on the top of the H-beam and the upper reinforcing steel plate, and the epoxy fiberglass board has a thickness of 20mm.

[0013] The beneficial effects of adopting the above-mentioned further solutions are: improving the thermal stability of the reinforced structure 2, reducing the thermal stress deformation of the metal base plate, achieving the effect of heat insulation, and improving its insulation performance, thereby blocking the current conduction between the base plate and the equipment inside the test chamber.

[0014] Preferably, the epoxy fiberglass board is provided with an anti-slip plate, and the anti-slip plate is made of 3mm thick stainless steel patterned plate.

[0015] The beneficial effects of adopting the above-mentioned further solution are: improving the wear resistance and anti-slip performance of the reinforced structure 2, reducing the wear caused by the transport vehicle traveling on the reinforced structure 2, and preventing the transport vehicle from slipping and moving during the test, thus preventing damage to the internal structure of the test chamber.

[0016] Preferably, the spacing between the center lines of the two sets of reinforcing structures corresponds to the wheel track of the external transport vehicle.

[0017] The beneficial effects of adopting the above-mentioned further solution are: it facilitates the movement of the transfer vehicle wheels between the two reinforced structures. Since the transfer vehicle moves straight in and out of the test chamber, reinforcement is only needed at the corresponding wheel track positions to meet the requirements, thus saving materials.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: The large test chamber bearing base plate of this utility model has two sets of reinforcing structures symmetrically arranged on the base plate for the transport vehicle to bear and move on the base plate. By adopting the reinforcing structure and the reasonable reinforcement design of the base plate, the bearing strength of the base plate is improved, which meets the requirements of the large test chamber under various high-load test conditions and ensures the safety and reliability of the test. By setting epoxy fiberglass board, the thermal stability of the reinforcing structure is improved, the thermal stress deformation of the metal base plate is reduced, and the thermal insulation effect is achieved.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Please see Figure 1-2 This utility model provides a technical solution for a large test chamber bearing base plate: a large test chamber bearing base plate includes a base plate 1, on which two sets of reinforcing structures 2 are symmetrically arranged. The reinforcing structure 2 includes: reinforcing ribs 21, with an H-beam 22 symmetrically arranged at both ends of the reinforcing ribs 21, an upper reinforcing steel plate 23 fixedly connected to the top of the reinforcing ribs 21, and a lower reinforcing steel plate 24 fixedly connected to the bottom of the reinforcing ribs 21.

[0024] In this embodiment, two sets of reinforcing structures 2 are symmetrically arranged on the base plate 1 for the transport vehicle to bear load and move on the base plate. By adopting the reinforcing structure 2 and the reasonable reinforcement design of the base plate 1, the load-bearing strength of the base plate 1 is improved, which meets the requirements of the large test chamber under various high-load test conditions and ensures the safety and reliability of the test.

[0025] Furthermore, the reinforcing rib plate 21 is fixed to the H-beams 22 at both ends, as well as the upper reinforcing steel plate 23 and the lower reinforcing steel plate 24 by welding, with the welding point spacing being 300-400mm.

[0026] In this embodiment, the reinforcing rib plate 21 is fixed to the H-beams 22 at both ends, as well as the upper reinforcing steel plate 23 and the lower reinforcing steel plate 24 by welding to ensure its structural stability. The spacing between the welding points is 300-400mm to ensure connection strength, reduce deformation, and avoid stress concentration.

[0027] Typically, the upper reinforcing steel plate 23 is welded to the top of the H-beams 22 at both ends, with the welding point spacing not exceeding 200mm.

[0028] In this embodiment, the upper reinforcing steel plate 23 is welded to the top of the H-beams 22 at both ends to ensure structural stability. Intermittent welding ensures connection strength, reduces deformation, and avoids stress concentration.

[0029] Specifically, the bottom reinforcing steel plate 24 is welded and fixed to the bottom of the H-beams 22 at both ends, with the welding point spacing not exceeding 500mm.

[0030] In this embodiment, the bottom of the lower reinforcing steel plate 24 is welded and fixed to the bottom of the H-beams 22 at both ends to ensure structural stability. Intermittent welding ensures connection strength, reduces deformation, and avoids stress concentration.

[0031] In addition, an epoxy fiberglass board 25 with a thickness of 20mm is provided on the top of the H-beam 22 and the upper reinforcing steel plate 23.

[0032] In this embodiment, by setting an epoxy fiberglass board 25 with a thickness of 20mm, the thermal stability of the reinforcing structure 2 is improved, the thermal stress deformation of the metal base plate is reduced, and the thermal insulation effect is achieved. At the same time, its insulation performance is improved, and the current conduction between the base plate and the equipment in the test chamber is blocked.

[0033] In addition, the epoxy fiberglass board 25 is equipped with an anti-slip plate 26, which is made of 3mm thick stainless steel patterned plate.

[0034] In this embodiment, by providing an anti-slip plate 26 made of 3mm thick stainless steel patterned plate, the wear resistance and anti-slip performance of the reinforced structure 2 are improved, the wear caused by the transport vehicle traveling on the reinforced structure 2 is reduced, and the transport vehicle is prevented from slipping and moving during the test, thus preventing damage to the internal structure of the test chamber.

[0035] It should be noted that the spacing between the centerlines of the two sets of reinforcing structures 2 corresponds to the wheelbase of the external transport vehicle.

[0036] In this embodiment, the two sets of reinforcing structures 2 are spaced apart and adapted to the transfer vehicle, which facilitates the movement of the transfer vehicle wheels between the two reinforcing structures 2. The transfer vehicle moves straight in and out of the test chamber, so only the corresponding wheel track positions need to be reinforced to meet the requirements, thus saving materials.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
