Description

TECHNICAL FIELD

[0001] The utility model belongs to movable, expandable building technical field, especially relate to an archaeological mobile expansion platform. BACKGROUND

[0002] With the high-speed development of economic construction and production, urban basic engineering construction (traffic, housing construction, etc.) projects are also advancing. In order to avoid serious damage to underground buried cultural relics caused by engineering construction, in recent years, archaeological investigation, exploration and excavation in conjunction with urban basic construction have gradually become the focus of archaeological work. Unlike proactive field archaeological investigation, exploration and excavation, urban basic construction archaeological projects have the characteristics of many points, wide range, small projects, short time, fast transfer and the like.

[0003] Currently, most of the city basic construction archaeological workers use simple board houses or container houses as offices and rest points for archaeological investigation, exploration and excavation. However, simple board houses and container houses are not convenient to move and transfer, and cannot meet the needs of short archaeological cycles, fast transfer, safe storage of excavated cultural relics, security and the like.

[0004] The invention patent application with the application publication number CN118144660A provides a vehicle-mounted self-loading and unloading self-adaptive leveling automatic expansion shelter, which comprises a main cabin module, two sides of the main cabin module are provided with expansion cabin modules, under the driving of a driving module, the expansion cabin modules can be unfolded or folded, a fixed floor is arranged in the main cabin module, the expansion cabin modules on both sides are hinged with the fixed floor through folding floors, in the unfolded state of the expansion cabin modules, the fixed floor and the folding floor can be flattened to support instruments, personnel and the like in the cabin. The shelter is also provided with a cabin self-loading and unloading vehicle module, the self-loading and unloading vehicle module comprises four supporting legs respectively located at the four corner positions of the main cabin module, the supporting legs can move towards and away from the main cabin module, and when the supporting legs move to the position farthest from the main cabin module, they are extended downward to support the ground to drive the upward movement of the shelter, drive the separation of the bottom of the cabin from the carrying vehicle, and then realize automatic loading and unloading of the vehicle.

[0005] The above-mentioned shelter can meet the requirement of carrying vehicle width limit in the folded state, and the expansion cabin modules can be extended outward to expand the use area when in use. At the same time, since the self-loading and unloading vehicle module is configured, the loading and unloading of the vehicle can be automatically completed in cooperation with the carrying vehicle when transfer and movement are needed, without the need for hoisting equipment, which is convenient and efficient.

[0006] However, if the above shelter is used as an office and rest point for the archaeological staff, considering the needs of safe storage of cultural relics, file arrangement, personnel living and resting, etc., the above shelter still has two main problems: first, the space is not enough. In the above shelter, the two expansion cabin modules are of the same size. In order to meet the width limit requirement, the two expansion cabin modules need to be completely accommodated in the main cabin module in the collapsed state. The shelter of this form can theoretically be enlarged to twice the volume in the expanded mode, which still cannot meet the needs of on-site arrangement of file cabinets, archaeological cultural relic storage boxes, archaeological tools and other equipment; second, in the collapsed state, there are two positions of the folded floor protruding in the main cabin module.

DETAILED DESCRIPTION

[0035] To facilitate the work and rest of urban archaeological staff, the basic technical concept of this utility model is to provide a mobile expansion platform that, while meeting the width restrictions of transport vehicles, can expand to create more space and facilitate the pre-installation of equipment. Specifically, the mobile expansion platform still includes a main cabin and outwardly expandable modules located on both sides of the main cabin. However, the two expansion modules are of different sizes. In the folded state, the smaller expansion module can be partially or entirely located inside the larger expansion module, resulting in an overlap in the width direction. This overlap can be expanded normally, thus increasing the expanded space to more than twice its original size. Simultaneously, a fixed floor is laid within the smaller expansion module, allowing for the pre-installation of relevant equipment on the fixed floor for easy access by staff after the space is expanded. The following detailed description of this utility model, in conjunction with embodiments, further illustrates this utility model.

[0036] Specific embodiments of the archaeological mobile expansion platform provided by this utility model:

[0037] As a most basic implementation example, such as Figures 1-5 As shown, the archaeological mobile expansion platform in this embodiment includes a main cabin 1 and expansion modules that can move outward relative to the main cabin 1 from opposite sides, namely, a first expansion module 4 and a second expansion module 2. When the first expansion module 4 and the second expansion module 2 move outward, they move away from each other, thus creating a larger space. When the first expansion module 4 and the second expansion module 2 move inward, they move closer to each other and can be retracted back into the main cabin 1, thus meeting the width requirements of transport vehicles during relocation. In the retracted state of the first expansion module 4 and the second expansion module 2, as... Figure 1 As shown, the archaeological mobile expansion platform in this embodiment still has a cuboid structure. Of course, to ensure that the first expansion module 4 and the second expansion module 2 can achieve the effect of expanding space (one room becomes three rooms) after moving outward, the inward-facing side of the first expansion module 4 and the second expansion module 2 should be an open structure.

[0038] like Figures 6-11 As shown, the first expansion module 4 and the second expansion module 2 are not the same size. The outer dimension (outer contour dimension) of the first expansion module 4 facing the second expansion module 2 (inward) is smaller than the inner dimension (inner contour dimension) of the second expansion module 2 facing the first expansion module 4 (inward). In the folded state, see [reference needed]. Figure 6 The first expansion module 4 is partially located inside the second expansion module 2, that is, in the width direction ( Figure 6In the left-right direction, the first expansion module 4 and the second expansion module 2 are partially overlapped, and the overlapped part can still be utilized after the first expansion module 4 and the second expansion module 2 are expanded, so that the expanded space can be more than doubled, thereby providing more working and resting space for the archaeological staff. It should be noted that the figure exemplarily shows a case where the first expansion module 4 is only partially located inside the second expansion module 2 in the folded state, but in other embodiments, the first expansion module 4 can be entirely located inside the second expansion module 2 in the folded state.

[0039] Meanwhile, the first expansion module 4 is paved with a fixed floor 6, and the fixed floor 6 is connected to the second expansion module 2 through a folding floor 7, both ends (width direction) of the folding floor 7 are hinged to the fixed floor 6 and the second expansion module 2, respectively, wherein the folding floor 7 includes two hinged plates, and as the first expansion module 4 and the second expansion module 2 approach each other, the plates in the folding floor 7 can be folded (see Figure 6 ), and as the first expansion module 4 and the second expansion module 2 move away from each other, the plates in the folding floor 7 can be folded with the fixed floor 6 (see Figure 11 ), and the specific material of the plates is not limited here, which can be wood, composite polymer material, metal, etc.

[0040] In the folded state, the internal space of the first expansion module 4 can be effectively utilized, and the fixed floor 6 can be pre-installed with the required related equipment, which can be directly utilized without secondary installation in the case of outward expansion of the first expansion module 4, which is convenient and efficient. For example, in some embodiments, as shown in Figure 8 、 Figure 9 and Figure 13 , the pre-installed equipment includes a bathroom 12, which includes a sink 13 and a toilet 14, for the convenience of the archaeological staff. Of course, the pre-installed equipment can also include equipment required for archaeological work, such as a cultural relic constant-humidity storage cabinet 15, a data cabinet 16, an equipment storage cabinet 17, etc., and an archaeological folding equipment 18 (such as a gas rib membrane archaeological tent) used during archaeological work. Of course, some related equipment arranged in the main cabin 1 or the second expansion module 2 during use, such as a nitrogen making and humidifying machine 19 and a nitrogen-filled cultural relic protection box 20, can be placed on the fixed floor 6, and can be flexibly moved to the corresponding position during use.

[0041] It should be noted here that the folding floor 7 is exemplarily shown to include only two floor panels, so that the folding floor 7 after being laid flat has fewer breakpoints (hinge points) of the floor structure, and the structure is stronger. Meanwhile, the space occupied by the floor panels in the width direction is also smaller, facilitating the arrangement of equipment. However, in other embodiments, it is not excluded that the folding floor 7 includes three or more floor panels.

[0042] To further utilize the space in the vertical direction, in a preferred embodiment, as shown in Figure 4 、 Figure 5 、 Figure 11 and Figure 13 , the top ends of the first and second extension modules 4 and 2 are open, and the main cabin body 1 is provided with first and second side plates 102 and 101 for the first and second extension modules 4 and 2 to pass outwards, respectively. The first and second side plates 102 and 101 are hinged to the main cabin body 1 and can swing up and down relative to the main cabin body 1. The main cabin body 1 is provided with a pitch driving device for driving the first and second side plates 102 and 101 to swing up and down, for example, a hydraulic cylinder, i.e., a pitch cylinder 5, can be used to drive the first and second side plates 102 and 101 to swing up and down, but in other embodiments, it is not excluded that a pneumatic cylinder, an electric push rod, or the like is used as the pitch driving device. When the first and second extension modules 4 and 2 are in the extended state, respectively, the first and second side plates 102 and 101 are correspondingly swung to tightly abut the open position of the top end of the first and second extension modules 4 and 2, respectively, and form the roof of the first and second extension modules 4 and 2, respectively, to prevent wind and rain. When the first and second extension modules 4 and 2 are in the folded state, the first and second side plates 102 and 101 are swung downward to tightly abut the main cabin body 1, which also has a protective effect. In this preferred embodiment, the first and second extension modules 4 and 2 do not need to be provided with a top plate, and the vertical space can be maximized.

[0043] On the basis of the above embodiments, in a further preferred embodiment, the position where the first side plate 102 and the first extension module 4 top opening are closely fitted, and the position where the second side plate 101 and the second extension module 2 top opening are closely fitted are provided with sealing structures. Specifically, the sealing structure can be provided on the side plate, or on the extension module, or both the side plate and the extension module. That is, at least one of the position of the first side plate 102 for fitting with the first extension module 4 and the position of the first extension module 4 for fitting with the first side plate 102 is provided with a sealing structure; at least one of the position of the second side plate 101 for fitting with the second extension module 2 and the position of the second extension module 2 for fitting with the second side plate 101 is provided with a sealing structure, wherein the sealing structure can be a rubber sealing ring. In the preferred embodiment, the sealing structure can make the side plate play a better protective effect.

[0044] In order to further optimize the use of vertical space, as a preferred embodiment, as shown in Figure 11 and Figure 12 , the first extension module 4 and the second extension module 2 can be directly guided and installed on the main cabin body 1. Specifically, the first extension module 4 is installed on the main cabin body 1 through the first guide structure at its lower end, and the first driving device for driving the first extension module 4 to move is located at the lower end of the first extension module 4. The second extension module 2 is installed on the main cabin body 1 through the second guide structure at its lower end, and the second driving device for driving the second extension module 2 to move is also located at the lower end of the second extension module 2. The guide structure can be the cooperation of slide rails and slide tracks (which can refer to the commonly used slide rails and slide tracks of furniture), specifically, the first guide structure includes a first slide track 22 and a first slide rail 23, and the second guide structure includes a second slide track 24 and a second slide rail 25. The number of slide rails and slide tracks can be flexibly set according to the carrying capacity. The driving device can adopt a hydraulic oil cylinder, that is, the first driving device is a first driving oil cylinder 28, and the second driving device is a second driving oil cylinder 27. Of course, in other embodiments, the use of an electric push rod is also not excluded. In this case, the second extension module 2 cannot interfere with the normal connection and movement of the first guide structure, therefore, the second extension module 2 is also provided with an avoidance channel for avoiding the first driving device of the first guide structure. Specifically, the avoidance channel can be an opening or a slot provided on the bottom plate of the second extension module 2. In the expanded state, the avoidance channel can be normally covered after the folding floor 7 is laid flat.

[0045] Compared with the other embodiments in which the first extension module 4 is guided and installed on the second extension module 2 (big in small), in this way, one floor space can be saved in the vertical direction, thereby providing more space for the archaeological staff.

[0046] Further, the first driving device (the first driving oil cylinder 28) and the second driving device (the second driving oil cylinder 27) are located at the middle position of the main cabin body 1 in the length direction. In this way, when the expansion module moves, the two sides in the length direction can be more balanced.

[0047] In order to facilitate the transition, the archaeological mobile expansion platform in the embodiment is also actually provided with telescopic legs 3 that can be self-loaded and unloaded. Specifically, the telescopic legs 3 can be translated along the width direction of the main cabin body 1 to be close to and away from the main cabin body 1. Specifically, as shown in Figure 10 , the driving device for driving the telescopic legs 3 to translate can be a translation oil cylinder 301. The telescopic legs 3 can be hydraulic legs. The telescopic legs 3 can be extended to lift the main cabin body 1 as a whole, and a vehicle can be moved below the main cabin body 1 to carry the archaeological mobile expansion platform. In the telescopic legs 3 are in the state of being translated and retracted, the width limit requirement of the vehicle can still be met.

[0048] In addition, in some preferred embodiments, as shown in Figures 7-9 and Figure 13 , the length of the main cabin body 1 is greater than the length of the second expansion module 2, so that in the length direction, a device placement space can be formed inside the main cabin body 1 for placing devices. If the second expansion module 2 is located at the middle position of the length direction of the main cabin body 1, device placement spaces can be formed on both sides of the second expansion module 2 in the length direction. If the second expansion module 2 is arranged close to one side of the length direction of the main cabin body 1, a device placement space can be formed on one side of the second expansion module 2 in the length direction. The power source of the whole archaeological mobile expansion platform is arranged in the device placement space. In the figure, a case in which each movable part is driven by a hydraulic oil cylinder is shown. The power source here refers to a hydraulic pump station 10. If each movable part adopts an electric driving scheme, the power source can be a power battery, such as a lithium battery. In the embodiment, the devices in the device placement space will not move with the first expansion module 4 and the second expansion module 2, and are relatively stable.

[0049] In addition to placing the power source, the device placement space can also be used to arrange a cultural relic storage rack 11 to safely store cultural relics. At the same time, in order to facilitate office work, the device placement space can also be used to arrange a visual conference device 8, such as a flat-screen television, a projection cloth, a smart screen, etc., and the archaeological staff can conduct a remote conference (such as Tencent conference). The space in the main cabin body 1 can also be used to place an office table 26, a chair, etc. In order to facilitate the rest of the archaeological staff, a bed, such as a folding bed 29, can be placed in the space inside the second expansion module 2.

[0050] In the case where the device placement space is located on both sides of the length direction of the second expansion module 2, as shown in Figure 7 and Figure 13 , a cabin door 201 for entering and exiting the platform can be arranged on the second expansion module 2.

[0051] Due to the high value of the unearthed cultural relics, considering the security needs, as shown in Figure 11 and Figure 13 The archaeological mobile expansion platform also includes a monitoring system, which includes a monitoring cabinet 9 and a camera 21, and the monitoring cabinet 9 is in communication connection with the camera 21. The connection mode and the camera 21 are prior art, and wireless connection can be used. The monitoring cabinet 9 can also be placed in the equipment placement space on one side of the second expansion module 2. The monitoring should be done inside and outside, so the camera 21 should be at least two, at least one of which is used to install inside the archaeological mobile expansion platform in the state of the two expansion modules expanding outward, and at least one of which is used to install outside the archaeological mobile expansion platform in the state of the two expansion modules expanding outward.

[0052] Finally, it should be noted that the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still be modified without the need to pay creative labor for the technical solutions recorded in the foregoing embodiments, or equivalent replacement for part of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
