Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary devices for bioreactor equipment, and specifically relates to a lifting platform for disassembling and assembling a reactor. Background Technology

[0002] A bioreactor is a device used in biological processes, primarily for culturing microorganisms or cells, or for conducting biochemical reactions to produce biological products such as drugs and vaccines. A bioreactor generally consists of a tank, a stirring paddle, a motor, and a gearbox. The gearbox adjusts the motor's output speed to a range suitable for the stirring paddle's operation. It not only reduces the motor's speed but also increases torque, ensuring the stirring paddle effectively mixes the liquid within the reactor. Prolonged use of a bioreactor can lead to wear, aging, or damage to its components. Disassembly and reassembly allow for inspection of critical components (such as seals) and timely replacement of damaged parts.

[0003] In existing technologies, disassembling the gearbox and motor typically involves using screws and adjusting with objects of varying heights, requiring 3-4 people to remove the motor and dual mechanical parts. Reassembly is even more time-consuming and labor-intensive. Sometimes, disassembly and reassembly can also cause injury to equipment and personnel. Utility Model Content

The threaded rod passes through the middle of the upper ends of the two outriggers and is threadedly connected to the fixed tube on one outrigger, while it is circumferentially connected to the middle of the other outrigger.

[0010] The support includes a circular support and a concave support, which can be detachably connected to the worktable.

[0026] To make the various technical features, advantages, or effects of the present invention more apparent and understandable, detailed descriptions are provided below through embodiments.

[0027] This embodiment specifically provides a lifting platform for disassembling and assembling a reactor, the structure of which is as follows: Figure 1 and Figure 2 As shown, it includes casters 1, base 2, lifting mechanism 3, and bracket 4.

[0028] There are several casters 1, for example, four, which are installed on the bottom of the base 2, such as on the four feet of the base, to enable the lifting platform to move on the horizontal plane.

[0029] The base 2 supports the lifting mechanism 3 and provides sufficient foundation height for the lifting platform to ensure the necessary ground clearance when carrying the bioreactor. For example, the height of the base 2 can be set to 14-20cm. Roller tracks 21 are provided on both sides of the upper surface of the base 2 for sliding connection with the lifting mechanism 3.

[0030] The lifting mechanism 3 is located above the base 2 and is used to drive the support 4 to rise and fall. The lifting mechanism 3 includes rollers 31, a scissor mechanism 32, hinges 33, a connecting shaft 34, a worktable 35, a threaded rod 36, and a fixed tube 37. The rollers 31 are respectively installed on both sides of the lower end of the scissor mechanism 32, located in the roller track 21 of the base 2, and slide in cooperation with the track. The scissor mechanism 32 consists of two arms, each of which is a rectangular frame structure. The intersection of the two arms is connected by two hinges 33, and a connecting shaft 34 is provided between the intersections to connect the two hinges 33 and achieve coaxial rotation.

[0031] A worktable 35 is positioned above the scissor lift mechanism 32. Slide rails are located on both sides of the bottom of the worktable. The upper ends of two arms are respectively placed within the slide rails. The upper end of one arm is fixedly connected to the slide rail via a fixing tube 37, while the upper end of the other arm can slide along the slide rail. A threaded rod 36 passes through the middle of the upper ends of both arms. One end of the threaded rod passes through the threaded hole of the fixing tube 37 and engages with it threadedly. The other end passes through the middle section of the other arm and can rotate circumferentially relative to this section but cannot move axially. By rotating the threaded rod 36, a helical action is generated between its threaded end and the fixing tube 37, thereby driving the two arms to open and close in a scissor-like manner, completing the lifting action. A rotating handle 38 is provided at the other end of the threaded rod 36 for manually driving the threaded rod 36 to rotate.

[0032] The support 4 includes a circular support 41, a concave support 42, a wing bolt 43, and fastening straps 44. Two fastening straps 44 are provided, fixed to the worktable 35 by the wing bolts 43. Each fastening strap 44 has a circular protrusion with a threaded hole at its center, used for threaded connection with the threaded supports at the bottom of the circular support 41 and the concave support 42, respectively. The function of the support 4 is to fix the gearbox shaft and the motor flange in the bioreactor.

[0033] Working principle and usage procedure of the lifting platform:

[0034] The lifting platform moves horizontally by rolling on the ground using four casters 1 at its bottom. Once the lifting platform is below the bottom of the bioreactor 5, the operator rotates the rotary handle 38 to rotate the threaded rod 36. The rotation of the threaded rod 36 acts on its threaded connection to the fixed pipe 37, causing the fixed pipe 37 to move forward axially. This forward movement of the fixed pipe 37 causes the rollers 31 at the lower end of the scissor mechanism 32 to slide along the roller track 21, thereby driving the retracted scissor mechanism 32 to gradually open, lifting the worktable 35 located above it.

[0035] During the lifting of the workbench 35, the operator adjusts the position of the fastening belt 44 as needed, so that the circular bracket 41 aligns with and supports the shaft 52 of the gearbox 51, and the concave bracket 42 aligns with and supports the flange 54 of the motor 53. Figure 3 As shown. After positioning is completed, the bracket 4 is reliably fixed to the worktable 35 by tightening the wing bolts 43.

[0036] Subsequently, the operator can rotate handle 38 in the opposite direction, causing threaded rod 36 to move fixed tube 37 backward, which in turn causes scissor mechanism 32 to retract, thus lowering worktable 35. After lowering, the entire lifting platform can be moved to the target position to complete the auxiliary operation for disassembling and assembling the reactor.

[0037] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any appropriate modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention should be covered within the protection scope of the present invention, which is defined by the claims.
