Detailed Description

In order to make the technical solution of the present utility model better understood by those skilled in the art, the technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.

Embodiment one:

as shown in fig. 1, the shock-resistant goods shelf adopting the sigma-shaped cross beam comprises a stand column 1 and a cross beam 2, wherein two ends of the cross beam 2 are connected with the corresponding stand column 1 through bolts, a plurality of round holes 5 are uniformly formed in the stand column 1 along the vertical direction, so that bolts can conveniently pass through the round holes, and the cross beam and the stand column are connected. A stay bar 3 is arranged between the two corresponding cross beams 2, and the end part of the stay bar 3 is connected with the corresponding cross beam 2. The cross beams are connected with the upright posts by bolts, the two back-to-back cross beams are connected by the grid stay bars, the sigma cross beams can be assembled on the ground by adopting a bolt connection mode, and then are integrally hoisted, and the installation mode has absolute installation cost advantage for the goods shelves above 20 m. Through the rigid fixing mode of bolt connection, the rigidity stability of the goods shelf is improved, and the shaking deformation of the goods shelf is reduced. A stay bar 3 is arranged between the two corresponding cross beams 2, so that the shock resistance of the cross beams 2 is improved, and the cross beams 2 are prevented from being deformed by impact. The number of the stay bars 3 may be one or plural, and the present application is not limited thereto. The cross-sectional shape of the stay 3 may be C-shaped, U-shaped, rectangular or square, but may be other shapes, which are not limited in this application.

Compared with the prior art, the method for fastening the cable is low in construction cost and high in installation efficiency by adopting a bolt connection mode: the installation mode of the whole modularized hoisting can be realized, the ground assembly and the installation are convenient, the time and the labor are saved, the modularized hoisting efficiency is high, and the construction period is saved. Most of the automatic stereoscopic warehouses in the industry are usually about 24m in height, and in recent years, some newly built ultrahigh warehouses reach 40m in height, a plurality of cross beams are required to be installed at high altitude, and the materials except upright post sheets are almost conveyed to high-altitude installers from the ground through manually pulling fixed pulleys or winches, so that the traditional material conveying is limited for the ultrahigh vertical warehouse with the height of 30-50 m except the installation efficiency, or the higher the vertical warehouse is, the lower the material conveying efficiency is; and the material conveying process is accompanied with safety risks of high-altitude falling objects.

And most of goods shelf part installation work performed at high altitude is moved to the ground for modularized assembly, so that the high-altitude workload of personnel is reduced. Modularized hoisting, carrying out overhead working crane, crank arm vehicle and lifting vehicle by means of more engineering equipment, reducing overhead working personnel and avoiding construction risks. The ground installation mode reduces the overhead work, and the operation is lighter, and the operating efficiency is high.

The shelf stability is high: the clasping beam/integral beam commonly used in the industry is spliced with the upright posts by adopting a column clamp, the joint of the upright post of the goods shelf and the cross beam belongs to semi-steel semi-hinge, and is not purely rigid and fixedly connected, the cross beam in the form is not suitable for the integral hoisting of the goods shelf during installation, the goods shelves can only be installed in the form of high-altitude parts or components, namely, after the upright post sheets are installed, the cross beams are installed at high altitude, so that the high-altitude operation amount is large, and the installation is time-consuming and labor-consuming; the sigma beam and the upright post are fixed by adopting a round hole penetrating bolt, firstly, the installation precision is high, secondly, the fixing mode is a rigid fixing joint, so that the rigidity stability of the goods shelf is improved, the shaking deformation of the goods shelf is reduced, and the use safety, reliability and durability of the goods shelf are improved.

As shown in fig. 2 and 3, the cross-sectional shape of the cross-beam 2 is a Σ shape, for example, the Σ -shaped cross-sectional shape of the cross-beam 2 is constituted by 9 folded surfaces of at least 8 folds. Compared with the prior art schemes in fig. 14-16, the cost of one sigma beam is saved by more than 10% compared with the beam in the prior art on the premise of meeting the same mechanical property.

Fig. 14 shows a conventional clasp beam in the industry, which is structurally formed by 2C-shaped rolled sections and performing clasp engagement twice to form a cross beam with a rectangular cross section, wherein in order to meet the requirement of double-C engagement, the upper and lower parts of the cross beam have to be overlapped, the steel consumption of the overlapped surface is increased without obviously improving the vertical bearing capacity of the cross beam, so that the cross beam has large steel consumption and high material cost. The beam clasp beam has high processing cost and high material cost. The conventional process for manufacturing the clasping beam in the industry comprises profile rolling, welding column clamping and surface spraying, and the complicated process leads to high processing cost. The clasping beam or the integral beam needs to be additionally welded with a column clamp, and after welding, pretreatment such as acid washing, phosphating, removing oil stains and the like on the surface is needed, and then the surface plastic spraying process is completed through electrostatic spraying and baking, so that the whole surface plastic spraying process has a certain influence on ambient air and water.

The sigma beam uses high-strength carbon steel or galvanized carbon steel, and the steel coil is rolled into a finished product on line at one time in an automatic high-precision rolling line without any manual participation in secondary processing, so that the precision of the sigma beam is higher than the manufacturing precision of a section bar of a clasp beam/integral beam which is commonly used in the industry and needs secondary processing and a welding post card. The modular installation is adopted in the installation link, the modular installation operation is carried out on the ground by utilizing the tool, the installation accuracy can be improved by means of the tool exploring die which is prefabricated in advance, and the quality inspection on the ground is sufficient for the goods shelf module, so that the ground quality inspection is more accurate than the high-altitude quality inspection.

As shown in fig. 1, mounting plates 4 are arranged at two ends of the supporting rod 3. The mounting plate 4 is connected with the cross beam 2 through at least one bolt, for example, four corners of the mounting plate 4 and the cross beam 2 can be connected through four bolts, and the connection is firm and shelf-stable.

A cross brace 8 and an inclined brace 9 are arranged between the opposite upright posts 1.

Embodiment two:

as shown in fig. 6-9, the outer side surface of the beam 2 is provided with an inner bushing 7, the inner bushing 7 is tightly matched with the side surface of the beam 2, the inner bushing 7 is fixed on the beam 2 through bolts, and the inner bushing plays a role in strengthening so as to prevent the beam from being deformed by impact. As shown in fig. 6, the inner bush 7 may be fixed to the cross member 2 by 4 bolts to stabilize the connection, and of course, as shown in fig. 11 to 13, the inner bush 7 may be fixed to the cross member 2 by only three bolts on the side, which is not limited in this regard.

The rest of the structure is the same as that of the first embodiment.

Embodiment III:

as shown in fig. 4 and 5, diamond hanging holes 6 and round holes 5 are formed in the upright posts 1 at intervals, and the upright posts can be matched with the clasping beams.
