Description

Technical Field

[0001] The utility model relates to the technical field of transfer appliances, and particularly relates to a detachable heavy-duty tray. Background Art

[0002] Heavy-duty trays are mainly used for storing and transporting goods. They can not only ensure that the goods are not scratched by foreign objects on the ground when placed, but also facilitate the combined operation of various equipment such as forklift lifting and hoisting during the transfer of goods. At present, the trays used in the market are mainly made of steel, and the tray columns are usually made of solid thickened steel. The steel trays are formed by welding technology, and the trays are welded into a whole. The surface of the steel trays will be treated with anti-corrosion to reduce the corrosion of the trays by the environment and improve the service life of the trays. The columns made of thickened steel increase the weight of the trays, making them inconvenient to carry and drill for installation. At the same time, other parts are welded to the steel trays, and the trays are a whole after being manufactured. If local parts are damaged, they cannot be replaced and can only be scrapped. During the process of warehousing and transportation, the steel trays may be accompanied by complex environments such as highways, railways, and sea transportation. They are also in contact with heavy objects for a long time or are bumped, and the surface anti-oxidation layer is easily peeled off, causing the steel trays to rust, reducing the service life of the trays, and increasing the warehousing and logistics costs.

[0065] The large angle member 7 is an L-shaped structure, including a first side and a second side.

[0066] The first outer plate 13 or the second outer plate 14 of the side upright column 9 is connected to the tray frame through a fixing plate 6. The lower part of the fixing plate 6 is connected to the first outer plate 13 or the second outer plate 14, and the upper part of the fixing plate 6 is connected to the tray frame. When the first outer plate 13 of the side upright column 9 is connected to the tray frame through the fixing plate 6, a set of large corner fittings 7 are provided on both the second inner plate 12 and the second outer plate 14 of the side upright column 9. The two sets of large corner fittings 7 are arranged oppositely, enabling the connection of the two sets of large corner fittings 7, the second inner plate 12, and the second outer plate 14 with only one set of bolts. The first side of the large corner fitting 7 is screwed to the side upright column 9, and the second side is riveted to the tray frame.

The two sets of large corner fittings 7 are arranged oppositely. The first side of the large corner fitting 7 is screwed to the side upright column 9, and the second side is riveted to the tray frame.

[0068] As a preferred technical solution of the present utility model, a support plate 3 is further included.

[0069] The support plate 3 is screwed to the bottom surface of the panel 5. The length direction of the support plate 3 is perpendicular to the length direction of the panel 5. The position where the support plate 3 is connected to the panel 5 is located in the middle of the panel 5. The support plate 3 is used to support the panel 5, further improving the load-carrying capacity of the tray.

[0070] As a supplement to the above technical solution, several groups of upright columns are provided at the lower bottom of the tray frame. One group of upright columns is arranged at the central position in the length direction of the support plate 3. The upright column located at the central position in the length direction of the support plate 3 is the central upright column 10.

[0072] With the large corner pieces 7, small corner pieces 8 and fixed plates 6 in the above embodiments, the disassembly of the corner columns 1, side columns 9, center columns 10 and trays is made more convenient, and the replacement of components is made easier. To reduce weight while ensuring strength, the lower surface of the side beam is two flat surfaces, and the hole pitch cannot be unified according to different installation directions. Therefore, two different sizes of corner pieces with different hole pitches are designed to meet the installation requirements. Figure 6 In Figure 9 When connecting along the length direction of the profile, the large corner piece 7 is used, and when connecting perpendicular to the length direction of the profile, the small corner piece 8 is used. For aesthetics and use safety, both the corner column 1 and the side column 9 adopt straight fixed plates on the outside and are connected with large and small corner pieces on the inside. At the same time, during installation, the nut head is on the outside and the screw is on the inside to prevent personnel from being scratched.

[0073] As a supplement to the technical solution of the present utility model, the column further includes a sealing plate 20. The reinforcing ribs include a semi-circular bridge 15 and a reinforcing plate 16.
