Description

Climbing assembly

Technical Field

The utility model relates to the technical field of storage shelves, in particular to a climbing assembly comprising an objective table and a shelf.

Background

In a warehouse rack system, for a cargo space located at a high level, a hoist (or called an elevator) is often used to hoist a cargo or a shuttle to a cargo space or a rail of a predetermined height. For example, CN205441638U discloses a three-dimensional warehouse, in which the lifting mechanism 12 drives the cargo platform 13 to lift. Two lifting wheels 20 are respectively arranged on two sides of the cargo carrying platform 13, and lifting rails 19 matched with the lifting wheels 20 are arranged on the upright posts 10 on two sides of the cargo carrying platform 13. Two lifting wheels 20 sandwich the lifting rail 19 on both sides for guiding a smooth lifting or lowering of the cargo bed 13.

The cooperation of the lifting wheels 20 with the lifting rail 19 belongs to a common guiding structure in a lifter. However, in specific use, this structure has a problem in that the fit clearance between the lifting wheel 20 and the lifting rail 19 becomes large after multiple uses, which causes a shaking problem. And, because the upright post structure is built in advance, the cargo carrying platform structure can only correspondingly match the lifting rail 19 in the upright post structure with the determined structural size, so that the cargo carrying platform cannot be elastically adapted to the lifting rails 19 with different sizes.

Therefore, a new technical solution is needed to solve the above technical problems.

Detailed Description

Referring to fig. 1 and 2, the utility model discloses a climbing assembly, which comprises a column guide rail 1 and a stage 2 lifting on the column guide rail 1. The objective table 2 is provided with a guide wheel assembly 3 which is matched with the upright guide rail 1. In the objective table 2, four guide wheel assemblies 3 are arranged, the four guide wheel assemblies 3 are divided into two groups, two guide wheel assemblies 3 in one group are positioned at one end of the upright guide rail 1 in the transverse direction and are arranged up and down, and two guide wheel assemblies 3 in the other group are positioned at the other end of the upright guide rail in the transverse direction and are arranged up and down, so that the four guide wheel assemblies 3 form a structure integrally clamped on the upright guide rail 1 to improve the lifting stability of the objective table 2. This arrangement of four idler assemblies 3 is a preferred manner of this embodiment, and the number of sets of engagement between idler assemblies 3 and column rails 1 provided in this embodiment may be set to the corresponding number of idler assemblies 3 by different column rail 1 types and requirements.

As shown in fig. 3 and 4, the stage 2 is provided with a plate-shaped bracket 31, the plate-shaped bracket 31 is located outside the column guide rail 1, and the guide wheel assembly 3 is mounted on the bracket 31. The idler assembly 3 includes two adjustment shafts 32 mounted on brackets 31. Each adjusting shaft 32 is provided with a roller 33, and the two rollers 33 respectively abut against two opposite side surfaces of the upright guide rail 1. The bracket 31 is provided with two through holes (penetrated by the adjusting shaft 32 and not numbered). The two through holes are arranged side by side and are axially parallel. The adjusting shaft 32 includes a first shaft body 321 disposed in the through hole, a second shaft body 322 extending from one end of the first shaft body 321 to form the through hole, and a third shaft body 323 extending from the other end of the first shaft body 321 to form the through hole. The first shaft 321 and the third shaft 323 are coaxially disposed. The axis of the first shaft 321 is eccentric to the axis of the second shaft 323. The roller 33 is mounted on the second shaft 322, and the third shaft 323 is fixed with an adjusting nut 324 and a circular dial 325. The dial 325 is located between the column guide 1 and the adjustment nut 324. Due to the design of the eccentric shaft, when the first shaft body 321 is rotated in one direction, the roller 33 is driven by the second shaft body 322 to approach the upright guide rail 1, and when the first shaft body 321 is rotated in the opposite direction, the roller 33 is far away from the upright guide rail 1. Therefore, in use, if a gap is generated between the roller 33 and the upright guide rail 1 during use, the fit between the roller 33 and the upright guide rail 1 can be directly adjusted without disassembling the stage 2 and the upright guide rail 1, so as to solve the hidden trouble of shaking caused by the enlarged fit gap. Meanwhile, the distance between the two rollers 33 can be increased or decreased by adjusting the eccentric shafts so as to adapt to the upright post guide rails with different width sizes, and the universality of the object stage 2 applied to the upright post guide rails with different sizes is improved. The dial 325 may record the angle of rotation of each adjustment nut 324 to facilitate adjusting the angular consistency of rotation of each adjustment nut 324.

A pair of guide wheel assemblies extending up and down are further arranged in the middle of the support 31, guide wheels 34 are mounted on the guide wheel assemblies, and wheel shafts of the guide wheels 34 are perpendicular to wheel shafts of the rollers 33. The guide wheel 34 is abutted against the end face of the upright guide rail 1, and the guide wheel 34 and the two roller assemblies semi-surround the upright guide rail to improve positioning accuracy, so that the object stage 2 is more stable when moving up and down along the upright guide rail 1. Two guide wheels 34 are arranged, one guide wheel 34 is positioned above the upright guide rail 1, and the other guide wheel is positioned below the upright guide rail 1 to balance moment during lifting.

There are many ways in which the utility model may be embodied, and the above description is only of a preferred embodiment of the utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be comprehended within the scope of the present utility model. The components not explicitly described in this embodiment can be implemented by using the prior art.
