Description

Technical Field

[0001] This utility model relates to the field of indoor and outdoor heavy object transportation technology, and in particular to a simple device for indoor and outdoor heavy object transportation. Background Technology

[0002] Currently, during the landscaping and decoration phases of building construction projects, materials cannot be directly dropped into the room due to the obstruction of the interior ceiling. Therefore, manual material transport is commonly used. When the materials to be transported are heavy and the indoor and outdoor clearance is limited, one approach is to use handcarts or place soft objects under the heavy objects for transport. However, the heavy objects are large, and excessive localized stress on the handcart tires or soft objects can cause friction damage or cracking of the finished tiles. This makes it impossible to transport heavy objects after the floor tiles have been installed, as it can easily damage the finished product. Another approach is to cut the materials into smaller pieces for manual transport, which reduces the weight of the materials being transported. The disadvantages of this approach are: 1. Manually handling materials for fine cutting can cause the materials to shrink in volume, and the uneven cut surfaces can easily cause localized damage to the materials; 2. When disassembled materials are transported and then reassembled, the seams will always have imperfections, damaging the original aesthetic appeal. 3. For slender vertical ornaments, the materials are divided and reassembled, which is difficult to reinforce and may easily collapse, posing a safety hazard and causing injury. The above-mentioned problems present challenges in transporting heavy objects such as ornaments as a whole.

[0003] Chinese utility model patent document CN2797277Y discloses a roller-type heavy object moving device, in which an elastic pad is set on the machine base, a roller is set on the elastic pad, several arc tiles are stretched longitudinally on the upper surface of the roller, and a rod is set inside the arc tiles. A continuous beam is placed on the roller, and the roller rotates inside the arc tiles, driving the continuous beam to move longitudinally along the machine base, thereby realizing the transportation of the continuous beam.

[0004] However, the above-mentioned device has the following disadvantages: (1) The structure of the base and roller is relatively bulky, making it difficult to install from outdoors to indoors, and disassembly is inconvenient; (2) The processing of the arc tile is complicated and cannot be processed on-site. Processing the arc tile will inevitably affect the thickness of the roller, which will lead to transportation difficulties; (3) The height of the roller cannot be adjusted, and its adaptability is poor when different heights are required for transportation; (4) The roller needs to be set longitudinally along the upper surface of the roller, requiring a large number of rollers and high cost. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of existing heavy object moving devices, such as difficulty in installation and disassembly from outdoors to indoors, difficulty in processing, and difficulty in adapting to transportation height, and to provide a simple device for transporting heavy objects indoors and outdoors.

[0006] In a first aspect, this utility model provides a simple device for transporting heavy objects indoors and outdoors, comprising: At least two longitudinal bars, all of which extend longitudinally between the indoor and outdoor areas, with adjacent longitudinal bars spaced laterally. A plurality of uprights are provided at intervals along the longitudinal direction of each of the longitudinal bars. All the uprights are arranged vertically. The lower ends of the uprights are supported on the indoor and outdoor ground. The upper ends of the uprights are detachably connected to the corresponding longitudinal bars. A plurality of crossbars are provided at intervals along the longitudinal direction of the longitudinal bars, and the crossbars are provided in the transverse direction. The crossbars are detachably connected to all the longitudinal bars. Several secondary keels are arranged longitudinally and fully laid on the crossbar; A flat plate, which is fully laid on the secondary keel; A plurality of rollers are arranged longitudinally at intervals, and the rollers are arranged laterally and placed on the flat plate.

[0007] The detachable connection of uprights, horizontal bars, and vertical bars allows for the erection of a longitudinally extending frame between indoor and outdoor areas. Installation and dismantling from outdoors to indoors are convenient, and the support stability is strong. Secondary keels are laid on the longitudinally spaced horizontal bars, with the horizontal bars serving as the main keels for support. A flat plate is fully laid on the secondary keels, providing a surface for the rolling rod to roll. This allows heavy objects to be placed on the rolling rod, and by applying external force, the rolling rod moves the heavy object between indoors and outdoors, completing the entire transport of the heavy object without the need for cutting. The secondary keels prevent heavy objects from falling due to lack of support in the gaps between the horizontal bars. Unlike existing technologies, the flat plate does not require ensuring the rolling rod remains stationary, simplifying its processing. Furthermore, by changing the connection height of the uprights, horizontal bars, and vertical bars, the height of the top of the rolling rod can be altered, making it adaptable to transport at different heights and offering greater versatility.

[0008] Preferably, only two longitudinal bars are provided, and the upright is connected to the back side of the two longitudinal bars. The top of the upright is higher than the top side of the longitudinal bars, and the two ends of the rolling rod extend beyond the upright outside the two longitudinal bars. When pushing the heavy object, the rolling rod will deviate at an angle during the rolling process. Under the limit of the upright, the rolling rod will not completely deviate from the movement trajectory, thus avoiding construction hazards.

[0009] Preferably, the flat plate has a downward slope from the outdoor area to the indoor area, with the slope being 1%-2%. This slope is appropriately placed towards the location where heavy materials are transported, allowing for the use of gravity to transport the heavy materials, making the transport more labor-saving. Furthermore, the slope is no greater than 2% to avoid instability during transport when the slope is too large.

[0010] Preferably, the spacing between two adjacent rollers in the longitudinal direction is 20cm-30cm, and the length covered by the rollers laid in the longitudinal direction is 1.2-1.5 times the longitudinal dimension of the heavy object. It is not necessary to lay rollers along the entire longitudinal direction of transportation, and the rollers that pass behind the heavy object can be transferred to the front for use, so that fewer rollers are required and the cost is lower.

[0011] Preferably, the secondary keel is made of wood, which provides good support stability and can also reduce vibration and buffer, thus minimizing the impact on indoor and outdoor ground.

[0012] Preferably, the timbers are spaced apart in both the horizontal and vertical directions, with gaps between longitudinally adjacent timbers, and the longitudinal gaps between two adjacent horizontal rows of timbers are staggered to prevent weak points in the vertical direction from being connected in the horizontal direction, thereby improving stability.

[0013] Preferably, some of the uprights are installed on the indoor high-span ground, and some of the uprights are installed on the outdoor low-span ground, which enables the transportation of heavy objects between the outdoor low-span ground and the indoor high-span ground.

[0014] Preferably, the longitudinal rods, uprights, crossbars, and rolling rods are all made of steel pipes, and the connections between the longitudinal rods, uprights, and crossbars are made of fasteners, which can enable quick installation and disassembly and ensure the stability of the system.

[0015] Preferably, the horizontal bar and the vertical bar are spaced at the same distance along the longitudinal direction of the vertical bar, and the horizontal bar, the vertical bar and the vertical bar are connected together by fasteners, which results in higher stability after connection.

[0016] Preferably, the spacing between two adjacent vertical poles is 50cm-100cm, which provides strong support.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a simple device for transporting heavy objects indoors and outdoors. Through the detachable connection of uprights, horizontal bars, and vertical bars, a frame extending longitudinally between indoors and outdoors can be erected. Installation and disassembly from outdoors to indoors are convenient, and the device offers strong support stability. Secondary keels are laid on the longitudinally spaced horizontal bars, with the horizontal bars serving as the main keels for support. A flat plate is fully covered on the secondary keels, providing a surface for the rolling rod to roll. Heavy objects can be placed on the rolling rod, and by applying external force to the heavy object, the rolling rod moves the heavy object between indoors and outdoors, completing the entire transport without the need for cutting the heavy object. The secondary keels prevent heavy objects from falling due to lack of support in the gaps between the horizontal bars. Unlike existing technologies, the flat plate does not require ensuring the rolling rod remains stationary, making its processing simpler. Furthermore, by changing the connection height of the uprights, horizontal bars, and vertical bars, the height of the top of the rolling rod can be changed, making it adaptable to transport at different heights and offering greater versatility.

[0020] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0021] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are set as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," "parallel," or "coaxial" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0023] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0024] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0025] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0026] Example 1 like Figures 1-6 As shown, a simple device for transporting heavy objects indoors and outdoors includes: at least two vertical rods 4, several uprights 3, several horizontal rods 5, several secondary keels 7, a flat plate 8, and several rolling rods 9; The detachable connection of uprights 3, horizontal bars 5, and vertical bars 4 allows for the erection of scaffolding that extends longitudinally between indoor and outdoor areas, such as... Figure 2 As shown, all the longitudinal bars 4 extend longitudinally between the indoor and outdoor areas, i.e., the longitudinal bars 4 are continuously installed between the indoor and outdoor areas. Adjacent longitudinal bars 4 are spaced apart laterally; several uprights 3 are spaced apart longitudinally along each longitudinal bar 4, and all uprights 3 are vertically installed. The lower ends of the uprights 3 are supported by the indoor and outdoor ground. Even if the indoor ground is tiled, the uprights 3 are statically loaded with the indoor ground and will not rub against the tiles, thus avoiding friction damage to the tiles. The upper ends of the uprights 3 are detachably connected to the corresponding longitudinal bars 4; several horizontal bars 5 are spaced apart longitudinally along the longitudinal bars 4, and the horizontal bars 5 are arranged laterally. The horizontal bars 5 are detachably connected to all the longitudinal bars 4. In an optional implementation, the longitudinal rod 4, the upright rod 3, and the horizontal rod 5 are all steel pipes. The connections between the longitudinal rod 4, the upright rod 3, and the horizontal rod 5 are made using fasteners 6, allowing for quick installation and disassembly while ensuring the system's stability. This enables rapid installation on indoor and outdoor ground surfaces. Figure 2 As shown. Furthermore, the horizontal bars 5 and the vertical bars 3 are spaced equidistantly along the longitudinal direction of the vertical bar 4, and the horizontal bars 5, vertical bars 3, and vertical bars 4 are connected at one point by fasteners 6, resulting in higher stability after connection. Furthermore, the spacing between two adjacent vertical bars 3 is 50cm-100cm, providing stronger support.

[0027] The secondary keel 7 is arranged longitudinally, and the secondary keel 7 fully covers the crossbar 5, such as Figure 3 As shown; the flat plate 8 is fully laid on the secondary keel 7, as... Figure 4 As shown; a plurality of the aforementioned rolling rods 9 are arranged longitudinally at intervals, and the rolling rods 9 are arranged transversely. The rolling rods 9 are placed on the flat plate 8, as shown. Figure 1 As shown.

[0028] Optional implementation methods, such as Figure 3 As shown, the secondary keel 7 is made of timber, providing good support stability and vibration damping, reducing the impact on indoor and outdoor floors. Furthermore, the timber is spaced apart both horizontally and vertically, with a gap 71 between longitudinally adjacent timbers, and the longitudinal gaps 71 between two adjacent horizontally adjacent timber rows are staggered, as shown... Figure 3 As shown, this avoids the vertical weaknesses from being extended horizontally, thus improving stability.

[0029] In an optional implementation, the flat panel 8 can be made of multiple pieces pieced together, such as... Figure 4 As shown, four sub-boards are assembled to form a flat panel 8. The flat panel 8 can be made of steel plate or template.

[0030] In an optional implementation, the flat plate 8 is in a horizontal state under the support of the secondary keel 7.

[0031] In an optional implementation, the flat plate 8 has a downward slope from the outdoor to the indoor, the slope being 1%-2%. The slope is appropriately laid towards the material and heavy object transport position, and the material and heavy object are transported by gravity, making the transport more labor-saving. The slope is not greater than 2% to avoid the rolling rod rolling too fast due to an excessively large slope, which could lead to transportation instability.

[0032] In an alternative implementation, the rolling rod can be made of rolling steel pipe, which has strong support capacity and can reduce rolling inertia while increasing the rolling radius, making it more stable when transporting heavy objects.

[0033] Optional implementation methods, such as Figures 1-6 As shown, the rolling rods 9 are laid longitudinally on the flat plate 8. The distance between two adjacent rolling rods 9 in the longitudinal direction is 20cm-30cm, which can stably support the heavy objects and avoid excessive stress on the heavy objects, thus preventing damage.

[0034] Optional implementation methods, such as Figures 7-8 As shown, the spacing between two adjacent rollers 9 in the longitudinal direction is 20cm-30cm. The length covered by the rollers 9 laid in the longitudinal direction is 1.2 to 1.5 times the longitudinal dimension of the weight 10. It is not necessary to lay rollers 9 along the entire longitudinal direction of transportation. The rollers 9 that pass behind the weight can be transferred to the front for use, which reduces the number of rollers 9 required and lowers the cost.

[0035] Optional implementation methods, such as Figures 1-6As shown, only two vertical rods 4 are provided, and the upright rod 3 is connected to the back side of the two vertical rods 4. The top of the upright rod 3 is higher than the top side of the vertical rod 4. The two ends of the rolling rod 9 extend beyond the upright rod 3 on both sides of the vertical rod 4. When pushing a heavy object, the rolling rod 9 will deviate at an angle during the rolling process. Under the limit of the part of the upright rod 3 that is higher than the rolling rod 9, the rolling rod 9 will not completely deviate from the movement trajectory, thus avoiding construction hazards.

[0036] Optional implementation methods, such as Figures 1-8 As shown, some of the uprights 3 are installed on the indoor high ground 2, and some of the uprights 3 are installed on the outdoor low ground 1. The indoor high ground 2 is higher than the outdoor low ground 1, making it difficult to transport heavy materials from the outdoor low ground 1 to the indoor high ground 2. By using a simple device for transporting heavy objects indoors and outdoors, it is possible to transport heavy objects between the outdoor low ground 1 and the indoor high ground 2.

[0037] The simple indoor / outdoor heavy object transport device described in this embodiment uses detachable connections of uprights 3, horizontal bars 5, and longitudinal bars 4 to erect a frame extending longitudinally between indoors and outdoors. It is easy to install and dismantle from outdoors to indoors and provides strong support stability. Secondary joists 7 are laid on the longitudinally spaced horizontal bars 5, with the horizontal bars 5 acting as main joists to support the secondary joists 7. A flat plate 8 is fully covered on the secondary joists 7, providing support for the flat plate 8. The flat plate 8 provides a surface for the rolling rod 9 to roll easily, allowing heavy objects to be placed on... On the rolling rod 9, by applying external force to the heavy object, the rolling rod 9 rolls on the flat plate 8, enabling the heavy object to move between indoors and outdoors, completing the entire transportation of the heavy object without the need to cut it. The secondary keel 7 prevents the heavy object from falling due to lack of support in the gaps between the crossbars. The flat plate 8 does not need to ensure that the rolling rod 9 does not move as in existing technologies, making its processing simpler. Furthermore, by changing the connection height of the uprights 3, crossbars 5, and longitudinal bars 4, the height of the top of the rolling rod 9 can be changed, making it adaptable to transportation at different heights and thus more versatile. It also eliminates the need to lay the rolling rod 9 along the entire longitudinal length of the transportation path, allowing the rolling rod 9 that was previously used behind the heavy object to be moved to the front, resulting in fewer rolling rods 9 required and lower costs. With the portion of the upright 3 above the rolling rod 9 providing a limit, the rolling rod 9 will not completely deviate from its trajectory, avoiding construction hazards.

[0038] The method for setting up a simple device for transporting heavy objects indoors and outdoors is as follows: Step 1: From the point where material weight 10 is unloaded at the outdoor low-span ground level 1 to the point where material weight 10 is placed at the indoor high-span ground level 2, erect the uprights 3, longitudinal bars 4, and transverse bars 5. Figure 2 As shown, fasteners 6 are used to overlap the accessories. The materials of the uprights 3, longitudinal bars 4 and transverse bars 5 can be quick-release steel pipes. The spacing of the uprights 3 can be adjusted appropriately according to the materials being transported. Step 2, as follows Figure 3 As shown, wooden beams are used to fully cover the area above the crossbar 5, and the wooden beams serve as secondary keels for support. Step 3, as follows Figure 4 As shown, a flat board 8 is fully laid on top of the timber, and the slope can be appropriately laid towards the material handling position to facilitate the handling of materials; Step 4, as follows Figure 1 As shown, a circular rolling steel pipe is placed above the flat plate 8 as a rolling rod, with both ends of the rolling steel pipe extending outward from the outside of the upright 3. Step 5, as follows Figures 5-8 As shown, a heavy object 10 is placed above the rolling steel pipe. By manually pushing and pulling the heavy object 10, the rolling steel pipe can rotate accordingly, thus enabling the transport of heavy materials between indoors and outdoors. This solves the technical problem of preventing the hoisting of heavy materials indoors due to obstruction by the indoor ceiling 21. Figures 5-6 As shown, it can directly transport heavy materials from outdoors to indoors without the need for cutting and reassembling the materials.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
