Angle iron bolts tight, steady as a rock

The wooden boxes of X-Bason heavy equipment are all made of high-strength plywood, Angle iron and bolts, the side and end of the box are combined with the box plate of the frame structure, and the chassis is made of wooden boxes made of sliding wood structure. The frame box is a large wooden box, its maximum weight and maximum external size of the contents are determined according to the usual transport conditions. Generally speaking, the outer length of the frame wooden box is below 12m, the outer width is below 3.5m, the outer height is below 3.5m, and the weight of the internal contents is within 500-20000kg. This kind of wooden box is mainly used to pack large mechanical products, and can also be used to pack small goods. The frame wooden box is also composed of base, side, end and top cover. The difference between them in structure is that the box board of the frame wooden box is the vertical plate: the frame wooden box board is outside, and the skeleton is all arranged in the box; When assembling the frame wooden box, first install two sides on the base and two sides, and finally bind the top cover; Both are based on the base to load, but the frame wooden box is more than the slip wooden box on the end and side of the frame structure, it is because of these frame structures, so that the frame wooden box can withstand the load is much larger than the slip wooden box.

The frame wooden box can be divided into class I (internal frame wooden box) according to the structure: the frame member is on the inside of the box board, which is suitable for general contents; Class II (outer frame wooden box) : The frame structure is on the outside of the box board, which is suitable for the whole in the direction of length and has sufficient rigidity of the internal contents. The basic provisions of its design take into account the circulation conditions normally expected for transport, handling and storage.

Example: a machine packing wooden box, box length 6000mm, box width 2500mm, box height 1700mm, so the distance between the columns is 6000mm÷4=1500mm, the column allowable load P=5× 10-3BL =5× 10-3 ×2500×1500=18750N. If the sum of sleeper and slide height is 400mm, the height of the column is 1700-400 =1300mm. According to the above calculation, the column section size should be 60mm×100mm. 4.11.3 The beam can be of the same section size as the column, and the beam support can be of 2/3 of the column section or of the same size as the column section. 4.11.4 Beams are allowed to be spliced, and the interface should be at the intersection of the support and the column. 4.12 Container Board 4.12.1 Thickness of carton plate. 4.12.2 The splicing form of the box board shall be tight according to the characteristics of the product. 4.12.3 The width of the box board shall not be less than 80mm. 4.12.4 The side plate should cover 2/3 of the height of the slide, and the box board should generally be placed vertically. 4.12.5 The color of the boxes used should be basically the same, and the surface should be flat. 4.13 Top of the box 4.13.1 In principle, the top square should be evenly arranged, and according to the inner width of the box, the beam supports can be added between the top square. The width of the beam brace is not small At 50mm, the thickness is not less than 2/3 of the thickness of the top square. 4.13.2 The size of the top square section shall be measured according to the weight of the machine tool and the width of the box. 4.13.3 When the lifting rope just passes through the side upper frame wood, and the box is long, the top of the box shall be strengthened. Machine equipment packing wooden box top reinforcement diagram 4.13.4 It is recommended to adopt a two-storey structure for the top plate. The inner top plate should be made of wood and laid along the direction of the box layer. The outer top plate can be made of plywood. If the plywood is selected, the inner and outer top joints should be staggered, and the joint position should be on the center line of the beam. 4.14 Reinforcement, ventilation and rain protection of wooden cases 4.14.15000kg or more wooden cases, the edges and corners should be equipped with edge iron or Angle iron, lifting rope should be equipped with lifting protection iron or slide protection iron Protective iron diagram 4.14.210000kg wooden cases should be reinforced with U-shaped nails, T-shaped iron or L-shaped iron at the joint of beam, brace and column Diagram of reinforcement measures for wooden cases 4.14.3 For non-moisture-proof wooden cases requiring ventilation, general holes shall be set up above both ends of the boxes, and window screens and rainproof covers shall be provided on the outer walls of the ventilation holes. 4.14.4 Wooden cases must be waterproof. When wood is used as the wall of the box, the inner wall should be lined with a layer of polyethylene low-foam waterproof barrier film or other waterproof materials with good performance; When plywood is used as the wall of the box, waterproof measures should be taken. 4.14.5 As far as possible, the waterproof material should be used in one piece. If it is necessary to splice, it should be bonded or heat-bonded welding. 4.14.6 Waterproof measures must be taken for the top cover of the box, and polyethylene low-foaming waterproof barrier film or other waterproof materials with good performance should be laid 4.15 Laying nails 4.15.1 The distance between the steel nails and the wooden edge should not be less than 20mm, the nails should be staggered, the nail head should not protricate from the outer surface of the box (except for the nails used for bamboo plywood), and the steel nails should not be bent and nailed at the joint of the box frame. 4.15.2 Round steel nails used shall comply with the provisions of GB349.
