Description

Technical Field

[0001] This utility model relates to the technical field of steel section placement racks, specifically a multifunctional steel section placement rack. Background Technology

[0002] Storage racks are core storage equipment used in industries such as machinery manufacturing, construction, and steel structure processing to store various types of steel, including steel pipes, reinforcing bars, angle steel, and channel steel. Their core function is to achieve orderly storage and convenient access to steel, while protecting the surface of the steel from damage and preventing safety hazards such as rolling and slipping. Ultimately, they improve material management efficiency, reduce loss rates, and are suitable for steel storage needs in various scenarios such as workshop storage and temporary storage on construction sites.

[0003] Most current mainstream steel storage racks are fixed welded structures, with the base length, column height, layer spacing, or cantilever length generally not adjustable. This means they can only accommodate steel of a single specification. When faced with mixed storage scenarios with multiple lengths and cross-sectional dimensions, they either cannot meet storage requirements, or the racks are prone to tilting when encountering uneven ground, causing materials to be placed unstably. Therefore, we propose a multi-functional steel storage rack. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a multi-functional steel placement rack, comprising: a first base frame 1, a second base frame 2 nested within the first base frame 1, and adjustment components 3 on the first base frame 1 and the second base frame 2. The adjustment components 3 adjust the size of the placement space of the rack. An adaptive component 4 is fixedly connected to the bottom of the first base frame 1, and the adaptive component 4 provides adaptive stability adjustment for the rack. The second base frame 2 is made of Q355B rectangular tubing and is clearance-fitted with the first base frame 1. The clearance is achieved through a sliding structure to allow for lateral expansion and contraction. The adjustment components 3, through lateral drive and vertical positioning structures, provide multi-dimensional size adjustment for the lateral length and vertical layer spacing of the rack. The adaptive component 4, through buffering, shock absorption, and grounding stability adjustment, can provide adaptive stability support on uneven ground with flatness deviations or under heavy impact, reducing the vibration amplitude of the rack.

[0022] The adjustment assembly 3 includes a slide rail 31 fixedly connected to the bottom of the first base frame 1, a slider 32 slidably connected inside the slide rail 31, the slider 32 being fixedly connected to the second base frame 2, a screw 33 passing through the slide rail 31, the screw 33 passing through the slider 32 and rotatably connected to the inner wall of the slide rail 31, one end of the screw 33 being away from the slider 32 and extending out of the slide rail 31; it also includes a column 34, the column 34 being fixedly connected to the first base frame 1 and the second base frame 2, a slide groove 35 being provided on the column 34, an adjustment hole 36 being provided inside the slide groove 35, a positioning block 37 slidably connected to the slide groove 35, a partition plate 38 being fixedly connected to the side of the positioning block 37 away from the slide groove 35, a positioning hole 39 being provided on the positioning block 37, the positioning hole 39 matching the adjustment hole 36, and a positioning pin 310 passing through the positioning hole 39 and the adjustment hole 36. The slider 32 is made of nylon and is fixed to the bottom of the second base frame 2 by bolts. The screw 33 is made of 45 steel and is heat-treated. The screw 33 passes through the slider 32 and is threadedly engaged with the slider 32. Both ends of the screw 33 are rotatably connected to the inner wall of the slide rail 31 through deep groove ball bearings. The screw 33 extends out of the slide rail 31 and is driven to achieve stepless adjustment of the lateral length. Four symmetrically arranged columns 34 are fixed to the base frame by bolts. The columns 34 have vertical grooves 35 on their upper edges. The grooves 35 have adjustment holes 36 in the height direction. The positioning block 37 is made of thick steel plate and is clearance-fitted with the grooves 35. The partition plate 38 is made of cold-rolled steel plate and is welded to the positioning block 37. Its length matches the base frame. The positioning hole 39 and the adjustment hole 36 are coaxially matched. After alignment, the positioning hole 39 and the adjustment hole 36 are connected by a positioning pin 310 to lock the height of the partition plate 38. The partition plate 38 can divide the placement space, avoid the collision of mixed steel sections, and reduce the surface damage rate.

[0023] In use, when horizontal adjustment is required, rotating the screw 33 causes it to rotate within the slide rail 31. Since the screw 33 and the slider 32 are threaded together and the slider 32 is limited by the slide rail 31, the slider 32 slides linearly along the slide rail 31 as the screw 33 rotates, thereby driving the second base frame 2 to extend and retract relative to the first base frame 1, realizing stepless adjustment of the horizontal length of the placement rack. When adjusting vertically, the positioning block 37 slides along the slide groove 35 of the column 34 to drive the partition plate 38 to adjust its height. When the positioning hole 39 on the positioning block 37 is aligned with the adjustment hole 36 in the slide groove 35, the positioning pin 310 can be inserted to lock the position of the partition plate 38. The vertical layer spacing is progressively adjusted through multiple sets of evenly arranged adjustment holes 36, ultimately adapting to the storage needs of different specifications of steel.

[0024] The adaptive component 4 includes a support leg 41 fixedly connected to the side of the first base frame 1 and the second base frame 2 away from the column 34. A rubber sleeve 42 is fixedly connected to the side of the support leg 41 away from the first base frame 1. A buffer spring 43 is provided inside the rubber sleeve 42. A telescopic rod 44 is provided inside the buffer spring 43. One end of the telescopic rod 44 is fixedly connected to the support leg 41, and the other end of the telescopic rod 44 is fixedly connected to a stabilizing seat 45. The outrigger 41 is bolted to a nitrile rubber sleeve 42 on the side away from the first base frame 1. The spring is a buffer spring 43 made of 65Mn steel. A telescopic rod 44 made of solid steel is coaxially installed inside the buffer spring 43. One end of the telescopic rod 44 is welded and fixed to the bottom of the outrigger 41. The stabilizing seat 45 is made of thick steel plate with diamond-shaped anti-slip texture on the bottom to increase friction with the ground. The buffer spring 43 and the rubber sleeve 42 form a double shock absorption, which can absorb vertical impact. The telescopic rod 44 limits the radial displacement of the spring. The stabilizing seat 45 increases the coefficient of friction through anti-slip texture, preventing the frame from sliding on various surfaces such as cement and tiles. It can also adaptively compensate for level deviation under uneven ground conditions, improving the overall adaptability of the equipment. When the placement frame is subjected to load-bearing steel or vertical impact, the force is transmitted through the support leg 41 to the rubber sleeve 42 and the internal buffer spring 43. The elastic deformation of the rubber sleeve 42 and the compression of the buffer spring 43 together absorb the impact energy and reduce the vibration of the frame. In addition, the four sets of components correspond to the four corners of the base frame, and can compensate for the ground flatness deviation through their respective elastic deformation, so as to achieve stable support of the placement frame under heavy load, vibration or uneven ground conditions.

[0025] Multiple sets of adjustment holes 36 are provided, and the multiple sets of adjustment holes 36 are arranged linearly and evenly, and the hole diameter of the adjustment holes 36 is the same. The uniform hole spacing of the multiple sets of adjustment holes 36 ensures the regular adjustment of the layer spacing, which can be adapted to the precise layering of steel sections of different heights. The hole edges are chamfered, and the chamfer design reduces the insertion resistance of the positioning pin 310, improving the ease of operation.

[0026] The first base frame 1 and the second base frame 2 are provided in two sets, and the other set of the first base frame 1 and the second base frame 2 are fixedly connected to the end of the column 34 away from the bottom, forming a frame structure as a whole. The two sets of base frames and the four columns 34 enclose a rectangular frame structure, which enhances the overall anti-overturning moment and significantly improves rigidity.

[0027] The adaptive component 4 has four sets, corresponding to the four corners of the first base frame 1 and the second base frame 2 respectively. The initial height of the legs 41 of the four sets of adaptive components 4 is the same. The four-point balanced support makes the verticality deviation of the frame small, avoiding tilting caused by uneven load. The multi-set design can also improve the stability under heavy load, keep the vertical deflection within a very small range, and at the same time disperse the local load on the ground, avoiding the tilting of the device caused by uneven ground bearing capacity.

[0028] In overall use, the size is adapted by adjusting component 3, lateral adjustment is achieved by rotating screw 33, the height of partition plate 38 is adjusted by sliding positioning block 37 along slide groove 35, and vertical adjustment is achieved by aligning positioning hole 39 with adjustment hole 36 and inserting positioning pin 310 to lock, thus preventing collisions between mixed steel sections. Simultaneously, adaptive component 4 transmits load through support leg 41, and rubber sleeve 42 and buffer spring 43 absorb heavy-load impacts, and can compensate for ground flatness deviations through elastic deformation. Ultimately, the frame structure and all components work together to achieve precise adaptation, stable support, and safety protection for steel sections of different specifications.

[0029] Example 2

[0030] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that a rotating handle 5 is fixedly connected to one end of the screw 33 that extends out of the slide rail 31. The rotating handle 5 provides a gripping space, and a rubber sleeve 42 can be installed on it to increase gripping friction, so that a single person can drive the screw 33 to rotate, thereby improving adjustment efficiency.
