Abstract
Description
Technical Field
[0001] This utility model relates to the field of building material stacking devices, and in particular to a multi-layer building steel stacking rack. Background Technology
[0002] Construction engineering refers to the physical engineering project formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. In construction engineering, structural steel is a type of strip steel with a specific cross-sectional shape and size, belonging to one of the four major categories of steel. Based on the different cross-sectional shapes, structural steel can be divided into simple cross-sectional steel and complex cross-sectional steel. Simple cross-sectional steel includes square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; complex cross-sectional steel encompasses I-beams, channel steel, steel rails, window frame steel, bent structural steel, etc. The device used to place structural steel is called a structural steel stacking rack.
[0003] However, through exploration, the inventors have discovered that this technical solution still has at least the following drawbacks: Existing stacking racks, in order to maximize space utilization, are typically designed as multi-layered structures, with steel placement generally accomplished through mechanical hoisting. However, this multi-layered stacking rack structure is relatively fixed, and during the handling of steel, interference can easily occur between upper and lower layers, leading to collisions. Furthermore, when lifting steel, the slings are obstructed by the steel in the upper layer, making the steel highly susceptible to collisions at the moment of lifting. This can not only damage the surface of the steel, affecting its quality and subsequent use, but also poses serious safety risks, threatening the lives of construction workers. This situation not only reduces construction efficiency but also increases construction costs and safety hazards, necessitating a more reasonable, safe, and efficient steel stacking rack design to solve these problems. Utility Model Content
[0004] The present invention aims to provide a multi-layer building steel stacking rack to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A multi-layered steel stacking rack includes an upright frame connected to two connecting columns. The two connecting columns are connected to several horizontal bars. The upright frame and the horizontal bars are connected to several sleeves. Each sleeve has a sliding groove. A telescopic rod is slidably connected to the inner wall of the sliding groove. The telescopic rod is connected to a first side baffle and a second side baffle. The first and second side baffles are connected to a support rod. The upright frame is rotatably connected to a rotating shaft. The rotating shaft is connected to several gears. The telescopic rod has a driving groove. The inner wall of the driving groove has a rack portion. The gears mesh with the rack portion. The upright frame and the telescopic rod are slidably connected to a supporting structure.
[0006] Preferably, the support structure includes a rotating rod, the upright has a first support groove, a first slider is slidably connected to the inner wall of the first support groove, the telescopic rod has a second support groove, a second slider is slidably connected to the inner wall of the second support groove, and the two ends of the rotating rod are rotatably connected to the second slider and the first slider, respectively.
[0007] Preferably, the cross-sections of the first support groove and the first slider are mutually matched convex shapes, and the longitudinal cross-sections of the second support groove and the second slider are mutually matched convex shapes.
[0008] Preferably, two adjacent sleeves are connected together by a purlin.
[0009] Preferably, the telescopic rod has a limiting groove, and a limiting plate is slidably connected to the inner wall of the limiting groove. The limiting plate and the inner wall of the sleeve are connected together by a pull rod.
[0010] Preferably, the upright and the connecting column are respectively connected to foot plates, and the foot plates are provided with fixing holes.
[0011] The beneficial effects of this technical solution compared to existing technologies are as follows: (1) This utility model achieves smooth extension and retraction of the telescopic rod by cooperating with the rotating shaft, gear and rack on the telescopic rod, thereby flexibly adjusting the position of the support rod, so as to avoid interference between the upper and lower layers when picking up and placing steel, reduce the risk of collision during the lifting process of the sling, effectively protect the surface quality of the steel, and improve the safety of operation and construction efficiency.
[0012] (2) This utility model achieves coordinated sliding support of the upright and telescopic rod through the support structure, including the rotating rod, the first slider and the second slider, which enhances the stability of the overall structure, prevents the telescopic rod from shaking or accidentally shrinking under load, ensures the safety and reliability of the stacking rack when stacking multiple layers, and reduces construction safety hazards.
[0013] (3) This utility model limits the range of movement of the telescopic rod by the cooperation of the limiting groove and the tie rod, preventing the telescopic rod from coming out of the sleeve. At the same time, it connects the adjacent sleeves with the purlin, further strengthening the overall integrity of the frame, improving the durability and service life of the equipment, and reducing maintenance needs.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments: like Figures 1 to 4 The multi-layer steel stacking rack shown includes an upright frame 1. The following describes the scheme in detail, taking the installation of three layers of horizontal bars 5 as an example. Figure 1 As shown, the upright frame 1 is connected to two connecting columns 2 on each of its left and right sides. The two connecting columns 2 together connect to three horizontal bars 5. The upright frame 1 and the horizontal bars 5 are connected to sleeves 6. The number of sleeves 6 in the same layer is greater than or equal to two. Figure 4 As shown, the sleeve 6 has a sliding groove 9, and a telescopic rod 7 is slidably connected to the inner wall of the sliding groove 9. A first side baffle 8 is connected to the left side of the telescopic rod 7, and a second side baffle 11 is connected to the top of the telescopic rod 7. The first side baffle 8 and the second side baffle 11 are jointly connected to a support rod 10. Figure 1 As shown, the support frame 1 is rotatably connected to a rotating shaft 12, and the rotating shaft 12 is connected to a gear 14. Figure 4 As shown, the bottom of the telescopic rod 7 is provided with a drive groove 20, and the inner wall of the drive groove 20 is provided with a rack part 21. The gear 14 meshes with the rack part 21. By rotating the rotating shaft 12, all gears 14 on the same side of the same layer can be driven to rotate synchronously. Through the meshing action with the rack part 21, all telescopic rods 7 are driven to move synchronously in and out of the sleeve 6, thereby realizing the extension and retraction function of the support rod 10. When picking up and putting down the steel, the support rod 10 can be extended outward to provide sufficient space for hoisting operations and effectively avoid collision with the upper layer of steel. After the steel is put in, it can be retracted to maintain a compact structure.
[0016] like Figure 1 As shown, the upright frame 1 and the telescopic rod 7 are slidably connected by a support structure, such as... Figure 2 As shown, the support structure includes a rotating rod 17, and a first support groove 15 is provided on the side wall of the upright 1. A first slider 16 is slidably connected to the inner wall of the first support groove 15. Figure 3As shown, the telescopic rod 7 has a second support groove 18 on its side wall, and a second slider 19 is slidably connected to the inner wall of the second support groove 18. The two ends of the rotating rod 17 are rotatably connected to the second slider 19 and the first slider 16, respectively. The cross-sections of the first support groove 15 and the first slider 16 are mutually matching convex shapes, and the longitudinal sections of the second support groove 18 and the second slider 19 are mutually matching convex shapes. When the telescopic rod 7 extends or retracts, the rotating rod 17 slides in the groove through the sliders at both ends and changes angle, forming a stable variable triangular support, which greatly enhances the bending stiffness and overall stability of the telescopic rod 7 under load, preventing it from sinking or swaying due to the load-bearing steel.
[0017] like Figure 1 As shown, several purlins 13 are connected between two adjacent sleeves 6, which effectively enhances the structural connection between sleeves 6 in the same layer and improves the integrity and rigidity of the frame.
[0018] like Figure 4 As shown, the telescopic rod 7 has a limiting groove 22, and a limiting plate 24 is slidably connected to the inner wall of the limiting groove 22. The limiting plate 24 and the inner wall of the sleeve 6 are connected together with a pull rod 23. The cooperation between the limiting groove 22 and the limiting plate 24 limits the extension and retraction stroke of the telescopic rod 7, preventing it from overextending and accidentally coming out of the sleeve 6, thus ensuring the safety of equipment operation.
[0019] like Figure 1 As shown, the bottom of the upright frame 1 and the connecting column 2 are respectively connected to the foot plate 3. The foot plate 3 has a fixing hole 4. The entire stacking rack can be firmly fixed to the ground by using anchor bolts and other components through the fixing hole 4, ensuring the stability and safety of the stacking rack during use.
[0020] The specific implementation process is as follows: The entire stacking rack is securely installed on the ground using anchor bolts through the fixing holes 4 on the foot plates 3 at the bottom of the upright frame 1 and connecting column 2. During hoisting operations, the worker can rotate the shaft 12, which, through the meshing transmission of the gear 14 and rack 21, drives all the telescopic rods 7 to extend outward synchronously along the sliding grooves 9 of the sleeve 6, thereby moving the support rod 10 to the outside of the frame, providing unobstructed operating space for the hoisting machinery and effectively preventing collisions between the slings and the upper steel sections. At this time, the rotating rod 17 in the support structure unfolds with the movement of the telescopic rods 7, forming a stable triangular support, ensuring that the support rod 10 does not sag or sway under load. After the steel section is stably hoisted onto the support rod 10, the shaft 12 can be rotated in the opposite direction to retract the support rod 10 to its original position. The limiting groove 22 and the limiting plate 24 cooperate to prevent the telescopic rods 7 from coming off. The entire operation process not only ensures the surface quality of the steel section but also significantly improves operational safety and work efficiency.
[0021] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
