Description

Technical Field

[0001] The present invention relates to the technical field of medical liquid preparation tanks, and specifically to a movable and liftable variable-speed high-efficiency medical liquid preparation tank. Background Technique

[0002] A medical liquid preparation tank refers to a liquid hydrogen storage tank, which is a cryogenic container for storing liquid hydrogen. Generally, it consists of an inner tank, an outer shell, a heat insulation structure, mechanical components for connection, measuring instruments, safety facilities, liquid and gas injection and discharge pipes, accessories, etc.

[0003] When the existing medical liquid preparation tanks are transported, they will generate certain vibrations with the bumps of the vehicle. At the same time, there is no good shock-absorbing device at the bottom of the medical liquid preparation tank, resulting in the medical liquid preparation tank at the upper end of the vehicle being shaken and impacted, and it is not very safe to use. For this reason, we provide a movable and liftable variable-speed high-efficiency medical liquid preparation tank to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to make up for the deficiencies of the existing technology, and provide a movable and liftable variable-speed high-efficiency medical liquid preparation tank, which solves the problem that the medical liquid preparation tank is shaken and impacted during transportation, resulting in unsafe use.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a movable and liftable variable-speed high-efficiency medical liquid preparation tank, including a double-layer medical liquid preparation tank, and two symmetrically arranged auxiliary moving mechanisms are arranged below the double-layer medical liquid preparation tank. The auxiliary moving mechanism includes a support frame fixedly connected to the outer surface of the double-layer medical liquid preparation tank; it also includes two symmetrically arranged shock-absorbing and buffering mechanisms. The shock-absorbing and buffering mechanism includes a first damping frame, the inner wall of the first damping frame is slidably connected with a second damping frame, the inner wall of the second damping frame is slidably connected with a first damping block, the upper surface of the first damping block is fixedly connected with a fixing frame, the inner bottom wall of the first damping frame is fixedly connected with four first dampers, and the top ends of the four first dampers are all fixedly connected to the bottom surface of the second damping frame. Two symmetrically arranged second dampers are fixedly connected to the inner wall of the second damping frame, and the mutually approaching ends of the two second dampers are both fixedly connected to the outer surface of the first damping block.

[0006] Furthermore, two symmetrically arranged rotating shafts are rotatably connected to the inner wall of the support frame, support legs are fixedly connected to the outer surfaces of the two rotating shafts, and moving wheels are rotatably connected to the inner walls of the two support legs.

[0007] By adopting the above technical solutions, the moving wheels can be completely retracted into the support frame, and the moving wheels can extend out of the support frame.

[0008] Further, the inner top walls of the support frames are each hinged with a hydraulic rod through a pin shaft, and the bottom ends of the two hydraulic rods are respectively hinged to the outer surfaces of the two support legs through pin shafts.

[0009] By adopting the above technical solution, the four hydraulic rods share the same controller. By extending the hydraulic rods, the bottom ends of the support legs and the moving wheels can be pushed out below the support frames.

[0010] Further, two symmetric second damping blocks are slidably connected to the inner wall of the first damping frame. The upper surfaces of the two second damping blocks are each hinged with a connecting rod through a pin shaft. A hinge seat is fixedly connected to the bottom surface of the second damping frame. One ends of the two connecting rods away from the second damping blocks are each hinged to the inner wall of the hinge seat through a pin shaft.

[0011] By adopting the above technical solution, there is a large damping between the second damping block and the inner wall of the first damping frame, thereby buffering the up and down movement of the second damping frame.

[0012] Further, three reset springs are fixedly connected to the mutually remote side surfaces of the two second damping blocks, and one end of each reset spring away from the second damping block is fixedly connected to the inner wall of the first damping frame.

[0013] By adopting the above technical solution, the reset springs can reset the second damping blocks after the second damping blocks move.

[0014] Further, the fixing frame is adapted to the support frame. A limiting block is slidably connected to the inner wall of the fixing frame, and the limiting block is adapted to the support frame.

[0015] By adopting the above technical solution, a limiting groove adapted to the limiting block is formed on the outer surface of the support frame. By passing the limiting block through the fixing frame and inserting it into the limiting groove of the support frame, the support frame can be fixed in the fixing frame.

The present invention is provided with a double-layer medicine liquid preparation tank, an auxiliary moving mechanism and a shock-absorbing and buffering mechanism. When a vehicle transports the double-layer medicine liquid preparation tank, the shock-absorbing and buffering mechanism can buffer and reduce shocks on the double-layer medicine liquid preparation tank, thereby preventing the double-layer medicine liquid preparation tank from being subjected to large shaking and impacts during bumpy transportation by the vehicle, thereby ensuring the safety of the double-layer medicine liquid preparation tank during transportation and improving the service life of the double-layer medicine liquid preparation tank.

[0023] 2. The present invention is provided with an auxiliary moving mechanism. After the vehicle transports the double-layer medicine liquid preparation tank, the support frame is taken out from the fixed frame and placed on the ground, and the four hydraulic rods are controlled to extend synchronously, thereby pushing the support legs to rotate along the rotating shaft and moving the moving wheels to the bottom of the support frame. At this time, the moving wheels are in contact with the ground, and the double-layer medicine liquid preparation tank can be artificially moved through the moving wheels, which facilitates the double-layer medicine liquid preparation tank to be moved to the desired position.

[0024] Other advantages, objectives and features of the present invention will be set forth in part in the following description and, in part, will be apparent to those skilled in the art based on an examination of the following or may be taught from the practice of the present invention.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1-8 , the present invention provides a technical solution: a movable and liftable variable-speed and efficient medical liquid preparation tank, including a double-layer medical liquid preparation tank 1. Two symmetrically arranged auxiliary moving mechanisms 2 are provided below the double-layer medical liquid preparation tank 1. The auxiliary moving mechanism 2 includes a support frame 21 fixedly connected to the outer surface of the double-layer medical liquid preparation tank 1. Two symmetrically arranged rotating shafts 22 are rotatably connected to the inner wall of the support frame 21. Support legs 23 are fixedly connected to the outer surfaces of the two rotating shafts 22. Moving wheels 24 are rotatably connected to the inner walls of the two support legs 23. The moving wheels 24 can be completely retracted into the support frame 21, and the moving wheels 24 can extend out of the support frame 21.

[0029] The inner top walls of the support frame 21 are respectively hinged with hydraulic rods 25 through pins. The bottom ends of the two hydraulic rods 25 are respectively hinged to the outer surfaces of the two support legs 23 through pins. The four hydraulic rods 25 share the same controller. By extending the hydraulic rods 25, the bottom ends of the support legs 23 and the moving wheels 24 can be pushed to extend below the support frame 21.

[0030] It further includes two symmetrical shock absorption and buffering mechanisms 3. The shock absorption and buffering mechanism 3 includes a first damping frame 31. A second damping frame 32 is slidably connected to the inner wall of the first damping frame 31. A first damping block 33 is slidably connected to the inner wall of the second damping frame 32. A fixing frame 34 is fixedly connected to the upper surface of the first damping block 33. Four first dampers 38 are fixedly connected to the inner bottom wall of the first damping frame 31. The tops of the four first dampers 38 are all fixedly connected to the bottom surface of the second damping frame 32. Two symmetrical second dampers 39 are fixedly connected to the inner wall of the second damping frame 32. The ends of the two second dampers 39 close to each other are both fixedly connected to the outer surface of the first damping block 33. The second damper 39 can buffer the horizontal movement of the first damping block 33.

[0031] Two symmetrical second damping blocks 35 are slidably connected to the inner wall of the first damping frame 31. Connecting rods 36 are hinged to the upper surfaces of the two second damping blocks 35 through pins. A hinge seat 37 is fixedly connected to the bottom surface of the second damping frame 32. The ends of the two connecting rods 36 away from the second damping blocks 35 are both hinged to the inner wall of the hinge seat 37 through pins. There is a large damping between the second damping block 35 and the inner wall of the first damping frame 31, so as to buffer the up and down movement of the second damping frame 32.

[0032] Three return springs 310 are fixedly connected to the outer sides of the two second damping blocks 35 away from each other. The ends of each return spring 310 away from the second damping block 35 are all fixedly connected to the inner wall of the first damping frame 31. The return spring 310 can reset the second damping block 35 after the second damping block 35 moves.

[0033] The fixing frame 34 is adapted to the support frame 21. A limiting block 311 is slidably connected to the inner wall of the fixing frame 34. The limiting block 311 is adapted to the support frame 21. A limiting groove adapted to the limiting block 311 is provided on the outer surface of the support frame 21. By passing the limiting block 311 through the fixing frame 34 and inserting it into the limiting groove of the support frame 21, the support frame 21 can be fixed in the fixing frame 34.

[0034] An installation plate 312 is fixedly connected to the outer surface of the limiting block 311. Four installation bolts 313 are threadedly connected to the inner wall of the installation plate 312. The four installation bolts 313 are all adapted to the fixing frame 34. By screwing the installation bolts 313 into the installation plate 312 and the fixing frame 34 at the same time, the installation plate 312 and the limiting block 311 can be fixed.

[0035] The inner wall of the double-layer medical liquid preparation tank 1 is fixedly connected with a plurality of annular partition plates 5 arranged at equal intervals. The outer surface of the double-layer medical liquid preparation tank 1 is fixedly communicated with a liquid hydrogen channel 6. Through the liquid hydrogen channel 6, liquid hydrogen can be added into or drawn out from the inside of the double-layer medical liquid preparation tank 1.

[0036] A fixed bottom plate 4 is arranged above the double-layer medical liquid preparation tank 1. The first damping frame 31 is fixedly connected to the upper surface of the fixed bottom plate 4. A reserved hole is arranged on the fixed bottom plate 4. The fixed bottom plate 4 can be installed in a transport vehicle through the fixed bottom plate 4 and screws.

[0037] Working principle: The fixed bottom plate 4 is installed on a transport vehicle and the support frame 21 is fixed in the fixed frame 34. During vehicle transportation, when the double-layer medical liquid preparation tank 1 is impacted in the horizontal direction, the first damping block 33 moves in the second damping frame 32 and is supported and buffered by two second dampers 39. At the same time, the damping between the first damping block 33 and the second damping frame 32 is relatively large, playing a buffering role. When the double-layer medical liquid preparation tank 1 is impacted in the vertical direction, the first damper 38 supports and buffers the second damping frame 32. At the same time, when moving up and down through the hinge seat 37, it will drive the second damping block 35 to move horizontally through the connecting rod 36. There is relatively large damping between the second damping block 35 and the first damping frame 31. At the same time, the impact in the vertical direction is transmitted as a horizontal impact force through the connecting rod 36, reducing the force received by the first damper 38. At the same time, the return spring 310 will reset the moved second damping block 35. When the vehicle transports the double-layer medical liquid preparation tank 1, the shock absorption and buffering mechanism 3 can buffer and shock-absorb the double-layer medical liquid preparation tank 1, ensuring the safety of the double-layer medical liquid preparation tank 1 during transportation.
