Description

Technical Field

[0001] This utility model relates to the field of hydraulic pallet truck technology, and specifically to a moving device for a chromatography column. Background Technology

[0002] Current power-assisted manual hydraulic pallet trucks and their control systems are simple to move individually, and their structure, including the frame, lacks protection during operation, resulting in the following problems:

[0003] (1) A standalone manual hydraulic pallet truck consists of a control handle and two pins, which is convenient and quick, but lacks safety protection. It can only transport items that are large in volume and occupy a large area, but it is easy to tip over when transporting tall and thin items.

[0004] (2) The ground roller support point of the standalone manual hydraulic pallet truck is a triangular support, and the amplitude during the turning process is large. It will tip over as the support force changes when turning.

[0005] Because the bottom of the chromatography column is a movable disk of 400×300mm, while the column height is 1800-2500mm, it may tip over during movement, thus damaging the equipment. Utility Model Content

[0006] To overcome the above problems, this utility model provides a moving device for a chromatography column, which can effectively prevent the column from tipping over when it passes over uneven road surfaces during movement, thus saving labor and maintenance costs.

[0007] The present invention adopts the following technical solution:

[0008] A moving device for a chromatography column includes a main outer support frame, an inner movable support frame, and a hydraulic lifter. The inner movable support frame is nested inside the main outer support frame. A guide sleeve is provided on the inner side of the main outer support frame, and the inner vertical support of the inner movable support frame passes through the guide sleeve. The hydraulic lifter is fixed to the main outer support frame, and its upper end is connected to the top horizontal support of the inner movable support frame for driving the inner movable support frame to move up and down along the guide sleeve. A foot assembly is provided at the lower part of the inner movable support frame. In the length direction of the foot assembly, a support beam located on the same side of the main outer support frame and the inner movable support frame is an openable movable guardrail support. The bottom end of the main outer support frame is provided with casters.

[0009] Preferably, the movable guardrail support includes an inner movable guardrail support and an outer movable guardrail support. The inner movable guardrail support is located on the upper part of the inner vertical support on one side of the inner support movable frame, and the outer movable guardrail support is located on the upper and / or lower part of the outer vertical support on one side of the main body outer support structure frame.

[0010] Preferably, two hydraulic lifters are provided, which are respectively located at the middle of opposite sides of the main body external support structure frame, and the pin assembly is located between the two hydraulic lifters.

[0011] Preferably, the inner support movable frame includes four inner vertical supports, each of which is respectively disposed through the guide sleeve on the inner side of the main body outer support structure frame.

[0012] Preferably, the movable caster is a lockable swivel caster that can rotate 180°.

[0013] The technical solution of this utility model has the following advantages:

[0014] This utility model is equipped with casters, a hydraulic lifter, and a movable guardrail support on the main external support frame and the internal movable support frame. After opening one end of the movable guardrail support, the chromatography column can be placed on the insert assembly. Then, the movable guardrail support is closed, and the hydraulic lifter is operated to raise and lower the chromatography column to the corresponding height.

[0031] like Figure 1As shown, this utility model provides a moving device for a chromatography column, including a main outer support frame 1, an inner support movable frame 2, and a hydraulic lifter 3. The inner support movable frame 2 is nested inside the main outer support frame 1. A guide sleeve 4, which is a steel pipe structure, is provided on the inner side of the main outer support frame 1 and is fixedly connected to the lower outer crossbeam 12 of the main outer support frame 1. The inner vertical support 21 of the inner support movable frame 2 passes through the guide sleeve 4. The hydraulic lifter 3 is fixed to the main outer support frame 1. The lower end of the hydraulic lifter 3 is fixed to the lower outer crossbeam 12, and the upper end of the hydraulic lifter 3 is connected to the top horizontal support 22 of the inner support movable frame 2, which is used to drive the inner support movable frame 2 to move up and down along the guide sleeve 4. The lower part of the inner support movable frame 2 is provided with a pin assembly 5, which is fixed together with the inner support movable frame 2 and moves up and down synchronously with the inner support movable frame 2. Along the length of the insert assembly 5, the supporting beam located on the same side as the main outer support structure 1 and the inner movable support frame 2 is an openable movable guardrail support 6. The bottom end of the main outer support structure 1 is equipped with casters 7, which can be moved manually. The casters 7 used are lockable swivel casters that can rotate 180°, and one caster 7 is installed at each of the four corners of the main outer support structure 1.

[0032] This utility model combines the movable guardrail support 6 with the main external support structure frame 1 and the internal movable support frame 2, which not only provides frame support but also achieves safety protection. It is improved according to the on-site working conditions to prevent the chromatography column from tipping over during transfer, ensuring that it avoids tipping over when passing through uneven road surfaces during the movement, and saving labor and maintenance costs.

[0033] The movable guardrail support 6 used in this utility model includes an inner movable guardrail support 61 and an outer movable guardrail support 62. The inner movable guardrail support 61 is located on the upper part of the inner vertical support 21 on one side of the inner support movable frame 2, and the outer movable guardrail support 62 is located on the upper and / or lower part of the outer vertical support 11 on one side of the main outer support structure frame 1. This utility model uses two quick-detachable inner movable guardrail supports 61 and outer movable guardrail supports 62, which facilitates maintenance and replacement of parts.

[0034] The two ends of the inner movable guardrail support 61 and the two ends of the outer movable guardrail support 62 are respectively connected to the corresponding inner vertical support 21 and outer vertical support 11 through plug-in connections. These connections can be made using fixing pins or snap-fit ​​structures. For example, one end of the inner movable guardrail support can be connected to the inner vertical support 21 via a pivot, allowing the inner movable guardrail support to rotate around the pivot. The other end of the inner movable guardrail support is plugged into another inner vertical support via a fixing pin. Of course, other connection methods can also be used between the inner and outer movable guardrail supports, which will not be elaborated here. When the inner and outer movable guardrail supports fully open the same end of the main outer support structure and the inner movable support frame, the chromatography column can be moved onto the plug assembly, and then the two layers of movable guardrail supports can be installed.

[0035] This invention features a hydraulic lifter 3 symmetrically positioned on both sides of the main external support frame 1, located at the midpoint of opposite sides. A foot assembly 5 is positioned between the two hydraulic lifters 3. Raising or lowering the foot assembly 5 requires two people to simultaneously operate the hydraulic lifters 3, causing the inner vertical supports 21 of the inner support movable frame 2 to move synchronously along the guide sleeve 4. The inner support movable frame 2 includes four inner vertical supports 21, each of which passes through the guide sleeve 4 located on the inner side of the main external support frame 1.

[0036] First, fully open both layers of movable guardrail supports. After the chromatography column is inserted into the insertion assembly, lower the anti-movement guardrail supports and insert the fixing pins. Then, two people simultaneously start operating the hydraulic lift. Once it reaches a certain height, release the hydraulic lift and unlock the locking device of the lower caster wheels. The column can be locked after reaching a certain height to prevent sudden raising or lowering during movement. The two layers of movable guardrail supports provide protection for the chromatography column during movement.

[0037] Any aspects not mentioned in this utility model are applicable to the prior art.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
