Technical Field

The invention relates to the field of chromatography, in particular to a chromatographic column head lifting device.

Background

Chromatography is a gel separation method, typically silica gel chromatography; separating fluid from gel in chromatographic column through molecular sieve, ion exchange and other reaction; the chromatographic column is a main body in the gel chromatography technology, generally a glass tube or an organic glass tube is used, gel is filled in the chromatographic column, when the homogenate is poured into a chromatographic column cylinder in the filling process of a manual chromatographic column, an operator needs to completely screw a column head out of the top end of an upright column, after the adding operation is finished, because the self weight of the chromatographic column head is heavier and is generally dozens of kilograms, a horizontal beam can cause a phenomenon that one end falls down due to the action of gravity when the horizontal beam is screwed out of the upright column, and at the moment, the falling end of the beam can be lifted to be placed at the fixed position of the top end of the upright column by the combined force of two persons; the operation mode increases the labor intensity of operators on one hand, reduces the working efficiency on the other hand, and has potential safety hazards.

Disclosure of Invention

The invention provides a chromatographic column head lifting device which comprises a cross beam, a support column bushing, a protective bushing, a lifting block and an upright column, wherein the support column is arranged on the cross beam, the lifting block is fixed at the upper end of the upright column, and the column head and the cross beam can be easily moved to the fixed position of the top end of the upright column by pushing the cross beam, so that the device is time-saving, labor-saving, safe and reliable.

In order to solve the technical problems, the invention adopts the technical scheme that: the utility model provides a chromatography column cap hoisting device which characterized in that: the lifting device comprises a cross beam, supporting columns, lifting blocks and upright columns, wherein the supporting columns are arranged on the cross beam; the lifting block is fixed at the upper end of the upright post.

The further technical scheme is as follows: in order to facilitate the assembly and disassembly when the supporting column is connected with the cross beam, the supporting column is connected to the cross beam through threads.

The further technical scheme is as follows: the support column lower extreme is equipped with the support column bush, because support column and promotion piece all are the metal material, frictional force is big during both contacts, can cause serious equipment wearing and tearing, and the effectual frictional force that reduces of installation of support column bush, convenient operation to play fine guard action to equipment.

The further technical scheme is as follows: be equipped with the hole on the promotion piece, be convenient for promote the piece and pass the stand, fix in the upper end of stand, through the size of adjusting the hole, can make things convenient for the promotion piece to use on other not unidimensional chromatography columns moreover.

The further technical scheme is as follows: the fixed position of the lifting block can be adjusted up and down.

The further technical scheme is as follows: in order to protect the upright and the lifting block, a protective bushing is arranged between the lifting block and the upright.

Adopt the produced beneficial effect of above-mentioned technical scheme to lie in: simple structure, the operation of being convenient for has improved work efficiency, has reduced intensity of labour, has avoided the potential safety hazard.

Detailed Description

The technical scheme of the invention is further explained below by combining the attached drawings of the invention.

As shown in fig. 1 and 2, a chromatography column head lifting device comprises a beam 1, a support column 2, a support column bushing 3, a protective bushing 4, a lifting block 5 and a column 6, wherein the support column 2 is mounted on the beam 1, and the lifting block 5 is fixed at the upper end of the column 6; by pushing the cross beam 1, the supporting column 2 passes through the inclined plane of the lifting block 5 to reach the fixed position at the top end of the upright post 6, and the difficulty of vertically lifting heavy objects is overcome by utilizing the inclined plane of the lifting block 5.
