Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for transporting steel components, specifically an auxiliary pad structure for loading irregularly shaped steel components. Background Technology

[0002] In the transportation of irregularly shaped steel components, the stability and efficiency of the loading process directly affect the overall logistics turnover efficiency and transportation safety. Traditionally, to achieve balanced support of the components on the flatbed truck during loading, a lattice frame made of timber is commonly used as an auxiliary support structure. While this method can meet the basic support requirements to a certain extent, long-term practical application has revealed many problems that urgently need to be solved, as follows:

[0003] Low operational efficiency: The erection of timber scaffolding requires repeated manual adjustment and splicing of timber, which is cumbersome and time-consuming. When returning empty, the timber scaffolding is prone to collapse due to the lack of a stable connection structure and the influence of external forces such as road bumps and vehicle turning. When loading again, it needs to be dismantled, cleaned and re-erected, which increases the amount of repetitive work, seriously restricts loading efficiency, and is difficult to meet the needs of efficient transportation of batches of irregular steel components.

[0004] Significant safety hazards exist: the support performance of wooden scaffolding depends on the strength and dryness of the timber, as well as the erection process. Long-term exposure to the outdoors makes the timber susceptible to moisture, corrosion, and insect infestation, leading to a decrease in strength. When bearing heavy components, it may break or deform, causing the components to tilt or slip. Furthermore, the timber is simply stacked and spliced ​​together without a fixed locking structure, making it prone to displacement and disintegration during transportation due to vibration and impact. This could damage components and pose a threat to the safety of transport vehicles, road infrastructure, and nearby personnel. Therefore, we propose an auxiliary support structure for loading irregularly shaped steel components to address the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary pad structure for loading irregularly shaped steel components, so as to solve the problems mentioned in the background art, such as the cumbersome operation of splicing timber, the easy collapse of the grid frame due to lack of stable connection when the empty truck returns, the need for repeated dismantling, cleaning and re-erection when loading again, which restricts the efficiency of batch transportation, and the easy decrease in the strength of timber due to the outdoor environment, which leads to breakage and deformation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An auxiliary pad structure for loading irregularly shaped steel components includes a transport vehicle and an auxiliary pad used in conjunction with the transport vehicle to transport the steel components. The auxiliary pad is arranged along the width direction of the transport vehicle. The auxiliary pad consists of two sets of rectangular tubes symmetrically distributed vertically, limiting members at both ends of the rectangular tubes, and an auxiliary height-adjusting square tube placed on top of the rectangular tubes. The two sets of rectangular tubes are vertically connected by welding a first connecting square tube and horizontally reinforced by welding a second connecting square tube. The top of the rectangular tubes has a insertion groove along the vertical direction of the first connecting square tube, and the insertion groove is rectangular in structure.

[0008] Preferably, the limiting member includes a limiting plate, which is connected to the outer wall of each end of the rectangular tube; the top of the limiting plate is coplanar with the top of the connected rectangular tube, and the bottom extends to below the bottom of the connected rectangular tube; the inner wall of the limiting plate abuts against the outer wall of the transport vehicle, and each limiting plate has a limiting hole near its bottom.

[0009] Preferably, the bottom of each auxiliary height adjusting square tube is connected to a plug block corresponding to the position of the plug slot. The plug block is movably inserted into the plug slot, and a 2-5mm gap is reserved between the outer wall and the plug slot.

[0010] Preferably, the outer walls on both sides near the center of the transport vehicle are evenly provided with through holes that are adapted to the limiting holes and used for bolt limiting.

[0011] Preferably, an anti-slip mat is attached to the bottom of the rectangular tube. The anti-slip mat is made of rubber and is used to enhance the friction between the auxiliary pad and the contact surface of the transport vehicle.

[0012] Preferably, the rectangular tube is made of Q355 material, and the outer wall of the auxiliary pad is coated with an anti-corrosion layer, which is an epoxy resin anti-corrosion layer, used to improve the corrosion resistance of the auxiliary pad.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The transport auxiliary bench of this application has a simple structure, is compatible with the width of the transport vehicle, has a stable structure, high practicality, and a modular overall structure. It does not require repeated manual adjustment and splicing, and is simple and efficient to operate. Compared with the cumbersome erection process of traditional wooden grid frames, it significantly reduces the labor intensity of operators and improves the convenience of loading operations.

[0015] 2. The auxiliary bench uses Q355 rectangular tubing as the main frame. It is reinforced by welding the first and second connecting square tubing in the vertical and horizontal directions, respectively, forming a symmetrical and stable overall structure. Compared with the traditional wooden grid frame, it avoids the problem of empty trucks collapsing due to the lack of fixed connections. It eliminates the need for repeated dismantling and erection, greatly reducing repetitive work and effectively improving the efficiency of bulk loading of irregular steel components, meeting the needs of efficient transportation.

[0016] 3. The auxiliary support stool is equipped with an auxiliary height-adjustable square tube at the top. Its bottom plug can be movably inserted into the rectangular plug slot of the rectangular tube, with a 2-5mm fitting gap reserved. It can be assembled and used according to the balance support requirements of irregular steel components. When not in use, the auxiliary height-adjustable square tube can be removed and placed in the gap inside the two symmetrically distributed rectangular tubes, without occupying vehicle space. At the same time, it is used with anti-slip mats to enhance the friction of the contact surface, ensuring stable support for irregular steel components of different specifications when loading the vehicle. This solves the problems of inconvenient height adjustment and poor adaptability of traditional wooden support.

[0017] 4. Transportation safety is significantly improved. On the one hand, the inner walls of the limiting plates at both ends of the rectangular tube abut against the outer wall of the transport vehicle, and the limiting holes cooperate with the through-hole bolts of the transport vehicle to achieve precise positioning and fixation of the auxiliary pad on the transport vehicle, preventing the pad from shifting during transportation. On the other hand, the epoxy resin anti-corrosion layer sprayed on the outer wall of the auxiliary pad can effectively resist the effects of outdoor moisture and corrosion, extending the service life of the structure. At the same time, the strength of the Q355 rectangular tube is much higher than that of traditional timber, which can avoid the risk of breakage and deformation when bearing heavy components, greatly reducing the probability of component slippage and damage, and ensuring the safety of transport vehicles, road facilities and surrounding personnel.

[0023] 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.

[0024] Please see Figure 1 and Figure 2 As shown, an auxiliary platform structure for loading irregularly shaped steel components includes a transport vehicle 1 and an auxiliary platform 2 used in conjunction with the transport vehicle 1 to transport the steel components. The auxiliary platform 2 is arranged along the width of the transport vehicle 1 and consists of two sets of rectangular tubes 21 symmetrically distributed vertically, limiting members 22 at both ends of the rectangular tubes 21, and an auxiliary height-adjusting square tube 23 placed on top of the rectangular tubes 21. The upper and lower sets of rectangular tubes 21 are welded together vertically through a first connecting square tube 211 and horizontally reinforced by a second connecting square tube 212, forming a stable symmetrical frame structure. A rectangular insertion slot 213 is provided on the top of the rectangular tube 21 along the vertical direction of the first connecting square tube 211, providing an installation base for height adjustment. The rectangular tubes 21, the second connecting square tube 212, and the first connecting square tube 211 are all made of Q355 material, and their outer walls are coated with an anti-corrosion layer, which is an epoxy resin anti-corrosion layer, to improve the corrosion resistance of the auxiliary platform 2.

[0025] The limiting component 22 includes a limiting plate 221, which is connected to the outer wall of the end of each rectangular tube 21. The top of the limiting plate 221 is coplanar with the top of the connected rectangular tube 21, and the bottom extends to the bottom of the connected rectangular tube 21. The inner wall of the limiting plate 221 abuts against the outer wall of the transport vehicle 1, and each limiting plate 221 has a limiting hole 222 near its bottom. At the same time, the outer walls of the two sides near the middle of the transport vehicle 1 are evenly provided with through holes 11 that are adapted to the limiting holes 222 and used for bolt limiting. The auxiliary pad 2 is fixed on the transport vehicle 1 by bolts passing through the limiting holes 222 and the through holes 11. An anti-slip pad 214 is attached to the bottom of the rectangular tube 21. The anti-slip pad 214 is made of rubber material to enhance the friction between the auxiliary pad 2 and the contact surface of the transport vehicle 1.

[0026] Please see Figure 1 , Figure 3 and Figure 4As shown, the bottom of the auxiliary height adjustment square tube 23 is connected to a plug block 231 corresponding to the position of the plug slot 213. The plug block 231 is movably inserted into the plug slot 213, and the outer wall is reserved with a gap of 2 to 5 mm between the plug slot 213 and the auxiliary height adjustment square tube 23. The height of the entire symmetrically distributed rectangular tube 21 can be adjusted by adjusting the auxiliary height adjustment square tube 23.

[0027] Please refer to the appendix for further details. Figure 1 In the middle, the height of the vertically symmetrically distributed rectangular tubes 21 is parallel to the height of the front platform of the transport vehicle 1. The height of the entire vertically symmetrically distributed rectangular tubes 21 is adjusted by the auxiliary height adjustment square tube 23. At this time, the height of the top of the vertically symmetrically distributed rectangular tubes 21 is higher than the front of the transport vehicle 1 and parallel. The front upright plate of the transport vehicle 1 can abut against the transported steel components to prevent the steel components from falling off the rear side after loading and transportation.

[0028] Usage procedure: Place the auxiliary pad 2 stably in the designated support area of ​​the transport vehicle 1 along the width direction of the transport vehicle 1, ensuring that the anti-slip pad 214 at the bottom of the rectangular tube 21 is completely in contact with the contact surface of the transport vehicle 1; at the same time, make the inner wall of the limiting plate 221 tightly abut against the outer wall of the transport vehicle 1 to initially achieve the lateral positioning of the auxiliary pad 2 and prevent left and right displacement; when the limiting hole 222 on the limiting plate 221 is aligned with the through hole 11 of the transport vehicle 1, pass the bolt through the limiting hole 222 and the through hole 11, and tighten the bolt to firmly fix the auxiliary pad 2 on the transport vehicle 1, so as to avoid the pad shifting during subsequent operations and transportation. Based on the balance support requirements of the irregular steel components to be loaded, adjust the auxiliary height adjustment square tube 23. Align the insertion block 231 at the bottom of the auxiliary height adjustment square tube 23 with the rectangular insertion slot 213 vertically opened along the first connecting square tube 211 at the top of the rectangular tube 21. Since there is a 2-5mm gap between the insertion block 231 and the insertion slot 213, the insertion block 231 can be easily inserted into the appropriate position in the slot. This ensures that the top height of the symmetrically distributed rectangular tubes 21 is higher than the height of the front platform of the transport vehicle 1, ensuring that the front upright of the transport vehicle 1 can abut against the steel components after the irregular steel components are loaded, preventing the steel components from falling from the rear. Use hoisting equipment to lift the irregular steel components smoothly and move them slowly above the transport vehicle 1, aligning the bottom of the components with the top of the rectangular tube 21 and the top of the auxiliary height adjustment square tube 23 of the auxiliary pad 2, ensuring that the center of gravity of the components falls within the support range of the auxiliary pad 2.

[0029] This application uses Q355 material rectangular tube 21 as the main body, and reinforces it by double welding in the vertical and horizontal directions through the first connecting square tube 211 and the second connecting square tube 212 to form a symmetrical and stable frame structure. Compared with the traditional wooden grid frame, it completely avoids the problems of collapse when returning empty and repeated erection. It does not require repeated manual dismantling and splicing, greatly reducing the amount of repetitive work, adapting to the efficient transportation needs of batch irregular steel components, and significantly improving loading efficiency.

[0030] The inner wall of the limiting plate 221 abuts against the outer wall of the transport vehicle 1, which can initially position the auxiliary pad 2 laterally and prevent the pad from shifting left and right on the transport vehicle 1. With the fixing method of the limiting hole 222, through hole 11 and bolt, the auxiliary pad 2 can be firmly locked on the transport vehicle 1, avoiding the pad from shifting due to road bumps and vehicle turning during transportation, thereby preventing the irregular steel components from tilting and slipping, and ensuring the safety of components, transport vehicles and people around the road.

[0031] The auxiliary height-adjustable square tube 23 is movably engaged with the insertion block 231 and the insertion slot 213, which can flexibly adjust the height according to the size and center of gravity distribution of the irregular steel components. The reserved gap of 2-5mm ensures the stability of the insertion and avoids installation jamming caused by dimensional errors. Compared with the cumbersome method of adjusting the height of traditional wooden squares by stacking layers, this structure is more convenient to operate and can quickly adapt to the balance support requirements of irregular steel components of different specifications, thus improving the versatility of the equipment.

[0032] The rubber anti-slip mat 214 can increase the friction between the auxiliary pad 2 and the transport vehicle 1, further preventing the pad from sliding during transportation or loading, and enhancing the support stability; the rubber material also has a certain cushioning property, which can reduce the hard collision between the component and the pad during loading and protect the surface of the component.

[0033] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
