Description

Rack component

Technical Field

The invention relates to the field of mechanical structure design. The invention relates specifically to a rack assembly for storing and holding items.

Background

In most strength tests, test tools such as rams are used that have a large mass, a large volume (e.g., a length of about 1 meter or more, a width of about 1.5-2 meters, a height of about 60 centimeters or more, and a mass of several hundred kilograms) and an uneven mass distribution. Such test devices, such as rams, are typically stored in racks of varying forms.

The common placing rack is simple in structure. However, the common rack has limited operating space when faced with articles such as rams which are heavy and require handling by vehicles and the like. This causes great difficulty for the tester to place/remove the article.

For example, chinese patent CN206519929U of heitong logistics equipment limited of eastern guan discloses a heavy mold rack. The rolling bearing device comprises two bearing beams, the two bearing beams are parallel to each other and arranged at intervals, the two ends of the bearing beams are fixedly connected with the corresponding cross beams respectively, and a plurality of rolling shafts are arranged between the two bearing beams. The placing frame disclosed by the invention enables a mould to enter from the inlet side of the placing frame and further slide inwards through the rolling shaft, the bearing beam at the tail end of the rolling shaft is provided with the stop inserting plate to prevent the mould from sliding off, and the placing frame can be matched with a hydraulic pallet truck or a trolley to store, take and transport the mould. Through the design to the concrete structure of rack device, this kind of rack though can be favorable to the access of heavy mould to a certain extent, still need direct action to carry out the access on heavy mould. This is not suitable for items that are not conveniently gripped directly, such as rams. In addition, the rack is difficult to fully utilize the characteristic that the travelling crane can hoist goods from the upper part, and still needs an operation space for articles to horizontally slide out.

For another example, chinese patent CN204675200U by suzhou eiyou electrical limited discloses a shelf. Which comprises an upper layer placing rack and a lower layer placing rack, wherein the upper layer placing rack comprises a plurality of placing rods, two ends of the plurality of placing rods are sleeved with pipe sleeves, and is fixed in the upper layer placing frame through a pipe sleeve, the lower layer placing frame comprises a fixed rod, the fixed rod is arranged between two upright posts, wherein, the fixed rod is articulated with a plurality of telescopic rods, one end of each telescopic rod is fixed with a lifting block which slides between the two support columns, a spacing mechanism is arranged between the lifting block and the support column, the upper layer of goods shelf is used for placing light containers, the lower layer is used for placing heavy containers, the heavy containers are placed on the telescopic rods, one end of each telescopic rod is articulated on the fixed rod, the inclination angle of each telescopic rod can be freely adjusted, the other end of each telescopic rod is fixed with the lifting block, the telescopic rod slides and goes up and down between the two upright posts, and the inclination angle is freely set according to the self requirement, so that the goods can be taken conveniently and adjusted. The goods shelf, particularly the lower-layer placing rack, improves the speed of taking goods out of the goods shelf, saves time and improves production efficiency. However, the patent adopts the structural design of the upright post matched with the telescopic rod and the sliding block, only improves the convenience of goods taking, and still cannot conveniently store the goods. Furthermore, such a pallet is not suitable for a precise actuator cylinder which requires smooth handling. Similarly, such racks are difficult to fully utilize the features of a traveling crane for lifting goods from above, and still require an operating space for articles to slide out horizontally.

For another example, chinese patent CN208514481U of xiangyang aviation science and technology ltd discloses a part placing rack for equipment maintenance of a cabin pressure regulator test bed. It includes the base, be equipped with the mount table on the base, the top of mount table is seted up flutedly, be equipped with the filter screen in the recess, the small opening has been seted up to the bottom of recess, the top of mount table is equipped with the collecting box, the small opening has been seted up to one side of collecting box, the collecting box is linked together through small opening and small opening, the symmetry is equipped with two sets of drawers in the mount table, the symmetry is equipped with hydraulic cylinder in the mount table, the equal fixed connection of rubber pad is on hydraulic cylinder's output, the one end of base is equipped with the link plate, the link plate has fixed to be connected on the base, a lateral symmetry of link plate is equipped with the layer board, the equal fixed connection. The rack of the invention is only suitable for small tools and parts and cannot meet the requirement of placing large articles such as the actuating cylinder.

In particular, in consideration of the storage of the actuating cylinders, a few actuating cylinders adopt a rail type structure similar to a drawer, and the corresponding tray can be drawn out when the actuating cylinders are placed or taken out, so that the operation is convenient. This results in a large waste of space and the stiffness of the rail foot of this construction is difficult to ensure for heavier, larger rams.

In view of the above, this state of the art does not meet the needs of laboratories that require large and frequent access/placement of items such as rams.
