Description

Technical Field

[0001] This utility model relates to the field of flatbed truck transportation of steel structures, specifically to a prefabricated steel structure flatbed truck with protective functions. Background Technology

[0002] When transporting steel structures on flatbed trucks, the installation of protective posts and the binding process are directly related to transportation safety. First, the protective posts can provide lateral protection for the steel structure pulled on the side of the flatbed truck, and the binding cables can stably bind the steel structure to the upper part of the flatbed truck, ensuring that the flatbed truck can stably transport the steel structure.

[0003] However, the protective pillars used on existing flatbed trucks have relatively simple structures. Furthermore, as a crucial support structure ensuring the lateral stability of goods, these pillars are prone to tilting during actual transport operations. Firstly, during long-term bearing of heavy components, the connection between the pillar and the flatbed truck's load-bearing surface is susceptible to loosening due to repeated stress, leading to deviations in the pillar's verticality. Secondly, when the transported components shift their center of gravity or are subjected to lateral impact, the pillar must withstand significant lateral forces. If its structural strength is insufficient or its fixing method to the flatbed truck is inadequate, tilting is highly likely. Once tilted, the pillar not only loses its effective lateral restraint on the components, failing to limit their lateral displacement during transport, but it may also cause abnormal contact between the tilted portion and the components, leading to surface scratches, deformation, and other quality problems. More seriously, the tilted pillar may disrupt the overall force balance of the flatbed truck, further exacerbating the swaying of components during vehicle turns and sudden braking, and even causing the pillar to break, resulting in components falling and other major safety accidents, severely impacting the safety and reliability of transport operations.

[0004] Meanwhile, when using flatbed trucks for transportation, sleepers, as an important auxiliary device for supporting components, often pose significant hidden dangers due to the lack of effective limiting and protective structures. Specifically, after the sleepers are laid directly on the load-bearing surface of the flatbed truck, they rely solely on the friction between themselves and the load-bearing surface to maintain their position. When the flatbed truck starts, brakes, or passes through bumpy sections, the sleepers are prone to lateral or longitudinal sliding due to the swaying of the components. This not only causes the support position to shift, disrupting the force balance of steel structures and other components, and leading to risks such as component tilting and collisions, but also may cause equipment damage due to the sliding sleepers pressing against the edge parts of the flatbed truck. At the same time, the sliding sleepers may become entangled or rub against the lashing cables, aggravating the wear of the cables and reducing the overall stability of the lashing system, posing a serious threat to transportation safety. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated steel structure transport flatbed truck with protective function, and to solve the following technical problem: how to enable the protective columns of the existing transport flatbed truck to effectively support the transported steel structure and to limit and reinforce the sleepers.

[0006] The purpose of this utility model can be achieved through the following technical solution: a prefabricated steel structure transport flatbed vehicle with protective function, comprising: a transport flatbed, wherein mounting holes are evenly opened on both sides of the upper surface of the transport flatbed, and protective components are evenly installed on the transport flatbed through the mounting holes on the upper surface;

[0007] The protective components include a first protective component, a binding cable, a sleeper, and a second protective component. The two ends of the sleeper are slidably engaged inside the first and second protective components. One end of the binding cable is wound around the top of the second protective component, and the other end of the binding cable is tied to the top of the first protective component. The bottom ends of both the first and second protective components are movably equipped with locking components, and the bottom sides of both the first and second protective components are movably equipped with limiting components.

[0008] The limiting component includes a positioning plate, with first positioning slots symmetrically formed on the outer surface of the positioning plate. A first limiting groove is formed on the side end face of the positioning plate, and a limiting shaft is slidably engaged inside the first limiting groove. A first insertion hole is formed on both end faces of the positioning plate. The engaging component includes an insertion block, with connecting rods fixedly connected to both ends of the insertion block. A handle is fixedly connected to the bottom end of the connecting rod, and a return spring is sleeved on the bottom outer surface of the connecting rod. Both the first and second protective components include protective columns. A winding reel is rotatably mounted on the top of the protective column. A second limiting groove is formed through the outer surfaces on both sides of the bottom end of the protective column. A positioning rod is inserted into the bottom of the protective column and at the upper edge of the second positioning slot. A tension spring is sleeved on the outer surface of the positioning rod. An insertion plate is provided at the bottom edge of the protective column. A second insertion hole is formed on the bottom surface and inside of the insertion plate. A second positioning slot is formed through the outer surface of the insertion plate at the bottom end of the protective column.

[0009] As a preferred embodiment of this utility model: the positioning insert plate is slidably engaged with the second limiting groove through the limiting shaft, and the outer surfaces of the first protective component and the second protective component are provided with wedge-shaped reinforcing ribs.

[0010] As a preferred embodiment of this utility model: the bottom of the positioning rod is inserted into the positioning plate through the first insertion hole, and the outer surfaces of the first protective component and the second protective component are hollow for installing the end of the sleeper.

[0011] As a preferred embodiment of this utility model, the positioning plate is slidably inserted into the bottom of the protective column through the second positioning slot.

[0012] As a preferred embodiment of this utility model, the connecting rod is inserted into the bottom of the protective column through the second insertion hole.

[0013] As a preferred embodiment of this utility model, the plug-in block is engaged with the positioning plug plate through a first positioning slot inside the bottom end of the plug-in plate.

[0014] As a preferred embodiment of this utility model, the plug-in plate is plugged into the upper surface of the transport plate through mounting holes.

[0015] As a preferred embodiment of this utility model: the top of the reset spring abuts against the bottom surface of the protective column, the top of the first protective component is provided with a binding shaft, and one end of the binding cable is bound to the first protective component through the binding shaft.

[0016] The beneficial effects of this utility model are:

[0017] (1) This utility model effectively limits and protects the sleepers by using the first protective component and the second protective component, which can significantly improve the stability during transportation and prevent them from sliding laterally or longitudinally when the vehicle starts, brakes or bumps. This not only ensures that the sleepers are always in the preset support position, ensures the force balance of the steel structure and other components, and prevents the components from tilting or colliding due to support offset, but also prevents the sleepers from sliding and causing squeezing damage to the edge parts of the transport flatbed. At the same time, the stable sleepers can reduce the entanglement and friction with the binding wire rope and sling, reduce the risk of wear of the lifting equipment, ensure the overall stability of the binding system, and provide a solid foundation for transportation safety.

[0018] (2) By setting the first protective component and the second protective component on both sides of the transport flatbed, this utility model can maintain vertical stability when transporting steel structures, and can give full play to its role in lateral stability protection of steel structures. By adopting a reinforced connection structure and optimizing the fixing method, the connection between the first protective component and the second protective component and the load-bearing surface of the transport flatbed can be strengthened, effectively avoiding tilting due to long-term load or lateral impact. The stable column can reliably limit the lateral displacement of steel structure and other components during transportation, prevent abnormal contact between components and other objects, thereby reducing quality problems such as surface scratches and deformation of components. In addition, the vertical stability of the first protective component and the second protective component helps to maintain the overall force balance of the transport flatbed. Under conditions such as vehicle turning and emergency braking, it can effectively suppress the shaking amplitude of components, reduce the risk of column breakage and component falling, and greatly improve the safety and reliability of transportation operations.

[0019] (3) By setting protective components on the upper surface of the transport flatbed, this utility model can effectively support the two sides of the steel structure on the upper surface of the transport flatbed, and can limit and reinforce the sleepers to prevent the steel structure from sliding and falling off the upper surface of the transport flatbed.

[0029] 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, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present utility model.

[0030] Please see Figures 1-7As shown, this utility model is a prefabricated steel structure transport flatbed vehicle with protective function, including: transport flatbed 2, the upper surface of transport flatbed 2 is evenly provided with mounting holes on both sides, and protective components 1 are evenly installed on the transport flatbed 2 through the mounting holes on the upper surface.

[0031] The protective component 1 includes a first protective component 13, a binding cable 14, a sleeper 15, and a second protective component 16. The two ends of the sleeper 15 are slidably engaged inside the first protective component 13 and the second protective component 16. One end of the binding cable 14 is wound around the top of the second protective component 16, and the other end of the binding cable 14 is tied to the top of the first protective component 13. The bottom ends of the first protective component 13 and the second protective component 16 are movably equipped with a locking component 12. The bottom sides of the first protective component 13 and the second protective component 16 are movably equipped with a limiting component 11.

[0032] The limiting component 11 includes a positioning insert plate 115. The outer surface of the positioning insert plate 115 is symmetrically provided with first positioning slots 114. A first limiting groove 112 is provided on the side end face of the positioning insert plate 115. A limiting shaft 111 is slidably engaged inside the first limiting groove 112. Both end faces of the positioning insert plate 115 are provided with first insertion holes 113. The engaging component 12 includes an insertion block 124. Connecting rods 123 are fixedly connected to both ends of the insertion block 124. A handle 121 is fixedly connected to the bottom end of the connecting rod 123. A return spring 122 is sleeved on the bottom outer surface of the connecting rod 123. The first protective component 13 and the second protective component... Each of the components 16 includes a protective column 166, a winding reel 167 rotatably mounted on the top of the protective column 166, a second limiting groove 161 penetrating through the outer surface of both sides of the bottom end of the protective column 166, a positioning rod 164 inserted into the bottom of the protective column 166 and at the upper edge of the second positioning slot 163, a tension spring 165 sleeved on the outer surface of the positioning rod 164, a plug-in plate 168 provided at the bottom edge of the protective column 166, a second plug-in hole 162 opened on the bottom surface and inside of the plug-in plate 168, and a second positioning slot 163 penetrating through the outer surface of the plug-in plate 168 at the bottom end of the protective column 166.

[0033] The positioning insert 115 is slidably engaged with the second limiting groove 161 via the limiting shaft 111, ensuring that the positioning insert 115 is always slidably connected to the bottom of the protective column 166 via the limiting shaft 111. The outer surfaces of the first protective component 13 and the second protective component 16 are provided with wedge-shaped reinforcing ribs, which can improve the support effect of the first protective component 13 and the second protective component 16. The bottom of the positioning rod 164 is inserted into the positioning insert 115 via the first insertion hole 113, which can position the positioning insert 115 on the bottom outer surface of the protective column 166 when the first protective component 13 and the second protective component 16 are not in use. The outer surfaces of the first protective component 13 and the second protective component 16 are hollow, which is used to install the ends of the sleepers 15, thereby limiting the slippage of the sleepers 15 during transportation and improving the protection effect on the operation of the steel structure.

[0034] The positioning insert plate 115 is slidably inserted into the bottom of the protective column 166 through the second positioning slot 163, and the connecting rod 123 is inserted into the bottom of the protective column 166 through the second insertion hole 162, which facilitates the control of the lifting and lowering of the insertion block 124. The insertion block 124 is engaged with the positioning insert plate 115 through the first positioning slot 114 inside the bottom end of the insertion plate 168, which can lock one end of the positioning insert plate 115 at the bottom of the insertion plate 168.

[0035] The plug plate 168 is plugged into the upper surface of the transport plate 2 through the mounting hole. The top of the return spring 122 abuts against the bottom surface of the protective column 166. The top of the first protective component 13 is provided with a binding shaft. One end of the binding cable 14 is bound to the first protective component 13 through the binding shaft, thereby providing a limiting protection for the top of the steel structure.

[0036] The working principle of this utility model is as follows: When transporting steel structures using the transport flatbed 2, the protective components 1 must first be evenly installed on the upper surface of the transport flatbed 2. First, align and insert the insertion plate 168 at the bottom of the protective column 166 with the mounting holes on both sides of the upper surface of the transport flatbed 2. Then, pull the positioning rod 164 upwards to compress the tension spring 165, thereby separating the bottom of the positioning rod 164 from the first insertion hole 113. Next, pull the positioning plate 115 to rotate 90 degrees. At this time, the positioning plate 115 will drive the limiting shaft 111 to slide up and down within the second limiting groove 161. It is necessary to ensure that one end of the positioning plate 115 is aligned with the second positioning slot 163 at the bottom of the protective column 166. Simultaneously, pressing down on the bottom of the grip 121 causes the connecting rod 123 to lift the insertion block 124, compressing the return spring 122. Then, the positioning plate 115 is pushed to engage with the second positioning slot 163 until one end of the positioning plate 115 engages with the insertion plate 168. During this process, the external force on the bottom of the grip 121 is released, the return spring 122 squeezes the grip 121, and the connecting rod 123 causes the insertion block 124 to descend. At the same time, the insertion block 124 engages with the first positioning slot 114 on the outer surface of the positioning plate 115, thereby restricting one end of the positioning plate 115 to the side of the insertion plate 168. This completes the installation of the first protective component 13 and the second protective component 16.

[0037] When the bottom of the second protective component 16 is inserted into the upper surface of the transport plate 2, the insertion plate 168 will be inserted into the mounting hole, so the limiting component 11 will be located on the outer side of the transport plate 2; in addition, the positioning plate 115 is inserted into the insertion plate 168, which can form a closed loop at the edge of the upper surface of the transport plate 2, thereby positioning the first protective component 13 and the second protective component 16 on both sides of the upper surface of the transport plate 2, effectively ensuring the stability of the installation of the first protective component 13 and the second protective component 16; in addition, the outer surface of the second protective component 16 is provided with wedge-shaped reinforcing ribs, which can further improve its support and protection capabilities for the steel structure;

[0038] When hoisting the steel structure, firstly, insert both ends of the sleeper 15 into the interior of the first protective component 13 and the second protective component 16 respectively, and then hoist the steel structure onto the upper surface of the transport flatbed 2, so that the sleeper 15 is placed between the steel structure and the transport flatbed 2. After the first layer of steel structure is stacked, continue to install sleepers 15 on top of it, and then continue to stack the steel structure until all the steel structure is stacked. Finally, pull the binding cable 14 through the top of the steel structure and bind it tightly to the binding shaft at the top of the first protective component 13. By inserting both ends of the sleeper 15 into the first protective component 13 and the second protective component 16, the sleeper 15 can be prevented from sliding during travel and bumps, thereby reinforcing and protecting the steel structure. Therefore, setting the protective component 1 on the upper surface of the transport flatbed 2 can not only effectively support the two sides of the steel structure on the upper surface of the transport flatbed 2, but also limit and reinforce the sleeper, preventing the steel structure from sliding and falling off the upper surface of the transport flatbed 2.

[0039] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
