Description

Technical Field

[0001] This utility model relates to the field of foam bag technology, specifically to a support frame for foam bags. Background Technology

[0002] Before performing LNG foaming operations, the foaming material needs to be removed from the storage container and its foam density tested to ensure that the quality and performance of the foaming material meet the requirements. In practice, a special foaming bag is used to collect the foaming material. After the foaming bag is filled with foaming material, it will continuously foam and grow for several minutes. In previous bag foaming experiments, researchers typically used a simple fixing method: hanging the foaming bag containing the foaming material directly on the wall with wire. This fixing method has significant drawbacks: as the foaming material continues to foam, its weight gradually increases, and the wire may break under the increased weight. Furthermore, this fixing method is inconvenient for testing emulsification and fiber-drawing times. Utility Model Content

[0003] The purpose of this utility model is to provide a support frame for foam bags to solve the problems of unstable fixing and inconvenient testing of foam bags in the prior art.

[0017] See Figures 1-2 A support frame for foam bags includes a support base 1, with a mounting ring 2 directly above the support base 1. The mounting ring 2 is a hollow cylinder. At least three support rods 3 are vertically arranged on the support base 1, and the support rods 3 are evenly distributed around the mounting ring 2. Each support rod 3 has a mounting seat 4 at its top. The mounting seat 4 is vertically fixed to the support rod 3. The side of the mounting seat 4 closest to the mounting ring 2 matches the shape of the mounting ring 2 and is fixedly connected to the mounting ring 2. A clamping mechanism 5 is fixed on the upper surface of each mounting seat 4. The clamping mechanism 5 has a first state and a second state. In the first state, one end of the clamping mechanism 5 abuts against the outer surface of the mounting ring 2. In the second state, one end of the clamping mechanism 5 is away from the outer surface of the mounting ring 2. In this embodiment, after the foam bag passes through the mounting ring 2, it is fixed and released by switching multiple clamping mechanisms 5, ensuring that the foam bag can be held on the support frame after being fixed. When the clamping mechanism 5 is in the first state, one end of it is tightly abutted against the outer surface of the mounting ring 2, thereby firmly clamping the foam bag between the mounting ring 2 and the clamp. When the clamping mechanism 5 is switched to the second state, one end of it moves away from the mounting ring 2, releasing the foam bag for easy replacement or adjustment. This structure is reasonably designed and easy to operate, which can effectively improve the convenience and stability of using the foam bag.

[0018] As a further embodiment of the present invention, the clamping mechanism 5 includes a fixed base 51 mounted on the mounting base 4. The fixed base 51 is fixed to the end of the mounting base 4 away from the mounting ring 2 by screws. An operating rod 52 is hinged to the end of the fixed base 51 away from the mounting ring 2. The other end of the fixed base 51 is provided with a guide hole. A piston rod 53 is provided in the guide hole. A linkage rod 54 is connected between the piston rod 53 and the operating rod 52. Both ends of the linkage rod 54 are connected to the piston rod 53 and the operating rod 52 respectively by pins. A clamping head 55 is provided at the end of the piston rod 53 away from the operating rod 52. Here, when the operating lever 52 is pushed towards the mounting ring 2, the piston rod 53 moves forward through the linkage rod 54, causing the clamping head 55 to tightly abut against the outer surface of the mounting ring 2. This is the first state of the clamping mechanism 5, which clamps and fixes the foam bag. When the operating lever 52 moves away from the mounting ring 2, the clamping head 55 moves away from the mounting ring 2. This is the second state of the clamping mechanism 5, which releases the foam bag for easy removal. Through the above structure, the clamping mechanism 5 can quickly switch states, achieving convenient fixing and releasing of the foam bag and improving operating efficiency.

[0019] As a further embodiment of this utility model, a connecting rib plate 21 is provided on the outer surface of the lower end of the mounting ring 2. Each mounting seat 4 has a mounting groove on the side near the mounting ring 2. After the connecting rib plate 21 is inserted into the mounting groove, it is fixed by welding, so that the mounting seat 4 and the mounting ring 2 are tightly connected. Here, by setting the connecting rib plate 21, the local strength of the mounting ring 2 can be enhanced, while ensuring the stability of the connection between the mounting seat 4 and the mounting ring 2, preventing the mounting seat 4 from deforming or falling off due to external forces, thereby improving the stability and service life of the overall structure.

[0020] As a further embodiment of this utility model, there are three support rods 3. The support base 1 is an equilateral triangular ring composed of three connecting plates. The three support rods 3 are respectively installed on the three corners of the support base 1. The foam bag achieves uniform force through three-point support, ensuring the stability of the foam bag on the support frame and avoiding tilting or falling off due to uneven force. At the same time, the three-point support structure can effectively distribute the weight of the foam bag, reduce the load of a single support point, and improve the load-bearing capacity of the foam bag.

[0021] As a further embodiment of this utility model, the support rod 3 includes a sleeve 31 and an inner rod 32. The sleeve 31 is vertically fixed on the support base 1. The inner rod 32 is installed on the top of the sleeve 31 and can move vertically within the sleeve 31. The top of the sleeve 31 is provided with several positioning holes 33 along the vertical direction. The inner rod 32 is provided with a positioning shaft 34, which can be engaged in the positioning holes 33. By adjusting the height of the inner rod 32 within the sleeve 31, the support requirements of foam bags of different sizes can be adapted, improving the versatility and flexibility of the device. When the positioning shaft 34 is engaged in the positioning holes 33 at different heights, the height of the support rod 3 can be quickly adjusted and locked, ensuring that the foam bag remains stable on the support frame. Here, by manually adjusting the height of the inner rod 32 within the sleeve 31 and using the positioning shaft 34 to engage in the positioning holes 33 at different heights, the height of the support rod 3 can be quickly adjusted and locked, ensuring that the foam bag remains stable on the support frame. At the same time, the foam bag can be adjusted to a suitable height position for testing and observation of the foam material.

[0022] As a further embodiment of this utility model, a distance sensor 6 is provided on the support base 1, and a position sensor 7 is provided on one of the sleeves 31 of the support rod 3. The distance sensor 6 is used to locate the bottom height of the foam bag, and the position sensor 7 is used to detect the foaming status inside the foam bag. After the foam bag is fixed on the mounting ring 2, the distance sensor 6 detects the distance between the bottom of the foam bag and the support base 1. When the bottom of the foam bag is not within the set range of the distance sensor 6, the distance sensor 6 will send a signal. At this time, the support rod 3 is adjusted to bring the bottom of the foam bag into the set range. When the bottom of the foam bag is within the set range, the distance sensor 6 sends a signal to the position sensor 7. The position sensor 7 monitors the foaming status inside the foam bag in real time. When the foaming height reaches the monitoring position of the position sensor 7, the position sensor 7 stops working and records the monitoring time.

[0023] As a further embodiment of this utility model, the support rod 3 is provided with scale lines 35, through which the expansion of the foaming material during the foaming process can be observed intuitively.

[0024] As a further embodiment of this utility model, a rubber ring is covered at the top of the mounting ring 2, and the rubber ring is sleeved and covers the mounting ring 2. The clamping head 55 is made of rubber, and the clamping mechanism 5 in the first state has the clamping head 55 abutting against the rubber ring. Here, the rubber ring can prevent the edge of the mounting ring 2 from tearing the foam bag. At the same time, the rubber clamping head 55 has a certain cushioning effect when clamping the foam bag, avoiding damage to the foam bag due to excessive clamping force. In addition, the cooperation between the rubber clamping head 55 and the rubber ring makes the clamping more stable.

[0025] The working principle of this utility model is as follows: The foam bag is a transparent cylindrical bag. When it is necessary to test the foam material, an appropriate amount of foam material is put into the foam bag, and then the foam bag is immediately placed in the support frame and installed in the ring. The top of the foam bag is turned outward. Then, the foam bag is fixed on the mounting ring 2 by the clamping mechanism 5. The height of the foam bag is adjusted by adjusting the height of the support rod 3. When the distance sensing device on the mounting base 4 detects that the bottom of the foam bag is within the set range, it sends a signal to the position sensor 7. The position sensor 7 starts to work and monitors the foaming inside the foam bag in real time. When the foam material expands to the set position of the position sensor 7, the position sensor 7 stops working and records the monitoring time.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
