Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and specifically to a transportation device for sandy areas. Background Technology

[0002] Sandy land refers to land covered by sand and largely devoid of vegetation, often referring to deserts. Construction work in deserts and other sandy areas typically involves the transport of construction materials and components to be assembled. To ensure efficient and orderly transport of these items, specific transport tracks are usually installed at the work site. Transport vehicles then carry the necessary items along these tracks for efficient and stable transport, saving manpower and resources while improving efficiency. Because the surface soil of sandy land is often loose and its bearing capacity is limited, tracks cannot be laid directly on the sand. Therefore, when laying construction tracks, it is usually necessary to reinforce the foundation along the track route, such as by digging pits and filling them with stones. In desert areas, crushed stone is scarce and must be transported from elsewhere. This not only results in low construction efficiency but also wastes materials such as crushed stone; especially when long-distance transport is required, it cannot meet the demands of the construction schedule.

[0003] Therefore, there is an urgent need to provide a transportation device for sandy areas that can be assembled quickly, improve construction efficiency, ensure construction schedule requirements, and at the same time guarantee structural reliability and ensure the high-speed and stable operation of the transported goods. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a transportation device for sandy areas that can achieve rapid assembly, improve construction efficiency, ensure construction progress requirements, and at the same time, ensure structural reliability and ensure high-speed and stable operation of the transported goods.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sand transport device, comprising multiple sets of floating pallets spaced apart on a transport path, transport tracks laid on each floating pallet, and a transport vehicle capable of traveling along the length of the transport tracks. The transport tracks include multiple sets of track section assemblies supported on each floating pallet and spliced ​​together. Each floating pallet includes a pallet shallowly buried in the sand, and the bottom of the pallet extends downward to form multiple anti-lateral displacement posts.

[0006] Furthermore, the track section assembly includes two parallel track beams and multiple reinforcing crossbeams fixed between the two track beams and arranged in parallel to each other.

[0007] Furthermore, the transport vehicle includes a transport vehicle body and a plurality of steel wheels correspondingly installed on the transverse sides of the transport vehicle body. The steel wheels are mounted on the upper surface of the corresponding side track beam, and an annular limiting platform is formed along the circumference of the steel wheel on the side of the steel wheel closest to the transport track.

[0008] Furthermore, the two ends of the track beam are respectively supported on two adjacent sets of floating trays, and the two reinforcing crossbeams near the ends of the track beam are detachably connected to the floating trays at the corresponding positions.

[0009] Furthermore, one end of the track beam extends outward along its length to form a locking platform, and the other end of the track beam is provided with a locking hole adapted to the locking platform. When two adjacent sets of track section components are spliced, the locking platform is fitted into the corresponding locking hole.

[0010] Furthermore, both the track beam and the reinforcing crossbeam are hollow steel pipes.

[0011] Furthermore, the floating pallet also includes multiple supporting base plates attached to the pallet plate. The two ends of the track section assembly are respectively pressed onto the corresponding supporting base plates. The middle part of the bottom end of the supporting base plate extends downward to form a limiting post. The pallet plate is provided with a limiting hole adapted to the limiting post. The limiting post is movably sleeved in the limiting hole, and the limiting post extends downward and is exposed outside the pallet plate. The exposed part of the limiting post is the anti-lateral displacement post.

[0012] Furthermore, the lower part of the limiting post has a tapered structure.

[0013] Furthermore, the pallet has a countersunk hole at the position corresponding to the support base plate, the support base plate is placed in the countersunk hole, and the top surface of the support base plate is flush with the upper surface of the pallet.

[0014] Furthermore, the pallet is made of stainless steel plate, and the edges and corners of the pallet are rounded.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] The sand transport device provided by this invention enables rapid assembly, improves construction efficiency, ensures construction progress requirements, and guarantees structural reliability, ensuring high-speed and stable operation of the transported goods. Specifically, since each track section is fixedly installed on a floating pallet, no additional reinforcement of the sand foundation is required, greatly improving the laying efficiency of sand track construction. In the floating pallet, the pallet plate increases the contact area with the sand, effectively ensuring the overall load-bearing capacity of the track. The anti-lateral displacement columns formed on the pallet plate enhance the bonding ability between the pallet plate and the sand, effectively preventing the pallet plate from sliding relative to the sand during operation, thus ensuring the smooth and reliable operation of the transport vehicle on the track. At the same time, the track sections are assembled by mutual splicing, which is highly efficient and facilitates the dismantling of the track sections later. Furthermore, the pallet plate is shallowly buried in the sand, which is equivalent to "floating" installation, requiring no additional fixing, making installation and dismantling convenient and construction efficiency high. In addition, the overall construction cost of this sand transport device is relatively low.

[0017] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0024] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only for illustrating the basic concept of the present invention; in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0025] Please see Figure 1-5A sand transport device includes multiple sets of floating pallets 1 spaced apart on a transport path, transport tracks laid on each floating pallet 1, and a transport vehicle 4 capable of traveling along the length of the transport tracks. The transport tracks include multiple sets of track section assemblies 2 supported on each floating pallet 1 and spliced ​​together. Each floating pallet 1 includes a pallet 101 shallowly buried in the sand 3. "Shallowly buried" means that at least a portion of the pallet 1 is submerged in the surface layer of the sand 3; alternatively, the pallet 1 can be completely submerged, but not too deeply, to prevent sand from shifting at the bottom of the pallet 1 due to wind, ensuring installation reliability. The bottom of the pallet 101 extends downwards to form multiple anti-lateral shift posts 101a. The anti-lateral shift posts 101 and the pallet 1 can be integral or detachably connected. It is understood that the anti-lateral shift posts 101 are also inserted into the sand. Multiple anti-lateral shift posts 101a are designed to prevent sand from shifting due to wind. The lateral shift column 101a enhances the bonding ability between the pallet 101 and the sand 3, effectively preventing the pallet 101 from sliding relative to the sand 3 during operation, ensuring the installation stability of the pallet 101, and thus ensuring the installation stability of the track section assembly 2. Furthermore, it is understood that the assembled track section assemblies 2 can form a trolley track for the transport trolley. Each track section assembly 2 can be pressed onto the floating pallet 1 by its own weight. Alternatively, it can be fixed to the floating pallet 1 by screws, clips, or other methods as needed, thereby enhancing the installation reliability of the track section assembly 2 and the floating pallet 1. Additionally, it is understood that the transport vehicle 4 can be an electrically driven or fuel-powered vehicle. The transport vehicle 4 can be designed with a load-bearing position matching the actual transported object 5, based on its structural form.

[0026] In the above structural design, since each track section component 2 is fixedly installed on the floating pallet 1, no additional reinforcement treatment is required for the foundation of the sandy ground 3, which greatly improves the laying efficiency of the sandy track construction. In the floating pallet 1, the pallet 101 increases the contact area with the sandy ground 3, effectively ensuring the overall load-bearing capacity of the track. The anti-lateral displacement column 101a formed on the pallet 101 enhances the bonding ability between the pallet 101 and the sandy ground 3, which can effectively prevent the pallet 101 from sliding relative to the sandy ground during the operation, thereby ensuring the stable and reliable operation of the transport vehicle 4 on the track. At the same time, each track section is assembled by mutual splicing, which has high assembly efficiency and is also conducive to the dismantling of the track sections later. In addition, the pallet is shallowly buried in the sand, which is equivalent to "floating" installation, which does not require additional fixing, making installation and dismantling convenient and construction efficiency high. Furthermore, the overall construction cost of this sandy transport device is relatively low, and it can be recycled as a whole as the work site changes.

[0027] In this embodiment, the track section assembly 2 includes two parallel track beams 201 and multiple reinforcing crossbeams 202 fixed between the two track beams 201 and arranged in parallel with each other. Here, they are welded together. In this structural design, the two track beams 201 can be used for vehicle operation. By designing multiple reinforcing crossbeams 202, specifically two in this case, the number of reinforcing crossbeams 202 can be appropriately increased according to the length of the track beams 201, forming an integral frame structure. This structure has good integrity and structural strength, and the overall installation is conducive to further improving the track laying efficiency.

[0028] In this embodiment, the transport vehicle 4 includes a transport vehicle body 401 and multiple steel wheels 402 correspondingly installed on both sides of the transport vehicle body 401. The installation of the steel wheels 402 and the transport vehicle body 401 can be designed with reference to the existing conventional vehicle body structure. Usually, the rear wheels are designed as drive wheels, which will not be described in detail here. The steel wheels 402 are mounted on the upper surface of the corresponding side track beam 201, and an annular limiting platform 402a is formed along the circumference of the steel wheel 402 on the inner side of the transport track. The annular limiting platform 402a is designed to protrude outward in the radial direction. The wheels are made of steel to ensure the fit strength between the wheels and the track beam 201. The annular limiting platform 402a designed on the steel wheels is beneficial to the driving stability of the transport vehicle during the driving process and prevents the transport vehicle 4 from derailing. The overall structure is simple and the operation is reliable.

[0029] In this embodiment, the two ends of the track beam 201 are respectively supported on two adjacent sets of floating pallets 1, which means that each set of track section components 2 has at least two sets of floating pallets 1 to support the track beam 201, further ensuring the overall load-bearing capacity of the track structure, thereby ensuring the smooth operation of the transport trolley on the track. The two reinforcing crossbeams 202 near the two ends of the track beam 201 are detachably connected to the corresponding floating pallets 1. Specifically, the reinforcing crossbeams 202 are detachably connected to the pallet 101 by bolts. By connecting the reinforcing crossbeams 202 to the floating pallets 1, the installation reliability of the track section components 2 is further improved, the overall integrity is good, and track deviation is avoided. Moreover, by designing the connection point on the reinforcing crossbeams 202, the structure is compact and does not affect the operation of the track beam 201.

[0030] In this embodiment, one end of the track beam 201 extends outward along its length to form a locking platform 201a, preferably a square column. The other end of the track beam 201 is provided with a locking hole 201b that matches the locking platform 201a. When two adjacent sets of track section components 2 are spliced, the locking platform 201a is fitted into the corresponding locking hole 201b. That is, in the two sets of track section components 2 spliced ​​together, the locking platform 201a on the track beam 201 of one set of track section components 2 is locked into the locking hole 201b on the track beam 201 of the other set of track section components 2. This locking splicing structure is easy to install, simple and reliable. The two track beams 201 at the splicing point are conducive to forming a seamless connection, which helps to ensure the smooth operation of the transport vehicle.

[0031] In this embodiment, both the track beam 201 and the reinforcing crossbeam 202 are hollow steel pipes, which have good structural strength, low material cost, and are conducive to lightweight design, easy handling and construction, and further improve construction efficiency.

[0032] In this embodiment, the floating pallet 1 further includes multiple supporting base plates 102 attached to the pallet 1. The two ends of the track section assembly 2 are respectively pressed onto the corresponding supporting base plates 102. A limiting post 102a extends downward from the center of the bottom end of each supporting base plate 102, forming a limiting post 102a. Here, the limiting post 102a and the supporting base plate 102 are welded together as a whole. The pallet 101 is provided with limiting holes adapted to the limiting post 102a. The limiting post 102a is movably fitted into the limiting hole, meaning that the supporting base plate 102 and the limiting post 102a can be pulled out separately, and the limiting post... The 102a is set downward through and exposed on the pallet 101. The exposed part of the limiting post 102a is the anti-lateral displacement post 101a, that is, the exposed part of the limiting post 102a serves as the anti-lateral displacement post 101a. In this structural design, during transportation, the supporting base plate 102 and the pallet 1 can be transported separately. Since there is no anti-lateral displacement post 101a on each pallet 1, it is convenient to stack and transport the pallets 1, thereby further improving construction efficiency. At the same time, the gravity of the track section assembly 2 can be used to ensure that the supporting base plate 102 is stably attached to the pallet 1. The structure is simple and easy to install.

[0033] In this embodiment, the lower part of the limiting post 102a has a conical structure; the conical structure facilitates the insertion of the limiting post 102a into the sand and also facilitates the dismantling and construction of the floating tray 1.

[0034] In this embodiment, the support plate 101 is provided with a countersunk hole 101b at a position corresponding to the support base plate 102, which is adapted to the support base plate 102. The support base plate 102 is placed in the countersunk hole 101b, and the top surface of the support base plate 102 is flush with the upper surface of the support plate 101. By setting the top surface of the support base plate 102 flush with the upper surface of the support plate 101, it is beneficial to the stable installation of the track section assembly 2. For example, the reinforcing crossbeam 202 of the track section assembly 2 can be supported on both the support plate 101 and the support base plate 102 at the same time, without obstructing the assembly of each track section assembly 2, which helps to improve the assembly efficiency of the track.

[0035] In this embodiment, the pallet 101 is made of stainless steel plate, and the edges and corners of the pallet 101 are rounded. Stainless steel plate has good structural strength, good load-bearing capacity, is not easily deformed, and has good rust resistance. The rounded edges and corners can prevent scratches to users during installation and transportation, thus improving safety.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
