Description

Technical Field

[0001] This utility model belongs to the field of mobile shelving technology, and more specifically, it relates to a track installation structure for mobile shelving. Background Technology

[0002] Mobile shelving is easy to control and safe and reliable. Each row of shelves is driven by a motor and moves along tracks laid on the ground via rollers mounted under the shelf. Its outstanding advantage is improved space utilization; a set of shelves only requires one aisle, while a fixed pallet rack only has one aisle serving two rows of shelves on either side of the aisle. Therefore, in the same space, mobile shelving has a much higher storage capacity than conventional fixed shelving.

[0003] Based on the above, the inventors have discovered the following problems: Currently widely used track systems mostly employ a segmented splicing installation method. Under long-term load and the thermal expansion and contraction effects caused by changes in ambient temperature, problems such as widening gaps and misalignment of adjacent track surfaces easily occur at track joints. These defects not only cause significant noise and noticeable bumps when equipment (such as racks and handling devices) passes through the joints, but also significantly affect the stability and positioning accuracy of the system, reducing the overall structural stability and durability.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a track installation structure for mobile shelves in order to achieve a more practical purpose. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a track installation structure for mobile shelves, which solves the problem that under long-term load and thermal expansion and contraction caused by changes in ambient temperature, the track joints are prone to widening gaps and misalignment of adjacent track surfaces.

[0006] The purpose and effect of this utility model's track mounting structure for mobile shelves are achieved through the following specific technical means:

[0007] A track mounting structure for a mobile shelving unit includes a base, a first track, and a second track. An installation groove is provided at the lower part of the connection between the first track and the second track. A connecting seat is installed inside the installation groove. Positioning blocks are installed at both ends of the upper part of the connecting seat. A buffer seat is installed between the two positioning blocks on the upper part of the connecting seat. The buffer seat has multiple buffer compression grooves.

[0008] Furthermore, the buffer seat is made of high-strength nylon, and the upper surface of the buffer seat is flush with the upper surfaces of the first and second tracks, and both ends of the buffer seat are in contact with the end faces of the first and second tracks.

[0009] Furthermore, the surface of the top positioning block is an outer inclined surface, and the inner side of the mounting groove is provided with an inner inclined surface that matches the outer inclined surface. A support top block is installed on the base at the lower position of the connecting seat, and the connecting seat is located on the support top block.

[0010] Furthermore, extension plates are bolted to both sides of the base, and columns are mounted on the extension plates. Support frames are provided on the columns, and the first and second tracks are located on the support frames.

[0011] Furthermore, the column is threaded, the two ends of the support frame are located at the threads on the column, and the column is provided with a first nut and a second nut at the upper and lower parts of the support frame through the threads.

[0012] Furthermore, the base is also evenly provided with a plurality of fixed support seats, which are staggered with the support frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the connecting seat is quickly positioned and fixed by means of inclined surfaces. A buffer seat is installed on the upper part of the connecting seat between two positioning blocks. The buffer seat is made of high-strength nylon, which has good wear resistance and buffering performance. At the same time, under the long-term load and the thermal expansion and contraction effect caused by changes in ambient temperature, the positioning blocks at both ends of the connecting seat can prevent the two rails from being misaligned to the left and right, thereby improving the overall stability and durability.

[0015] In this invention, the height of the support frame can be finely adjusted by adjusting the position of the nut, ensuring that the track mounting surface is flat. The buffer seat fills the gap between the tracks and provides elastic cushioning through the buffer compression groove. When the shelf moves, the wheel set passes through the connection point and is smoothly transitioned by the buffer seat, effectively reducing impact and wear. Attached Figure Description
