Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction tools, and in particular to a material unloading platform for building construction. Background Technology

[0002] During building construction, cantilevered unloading platforms are often fixed in the upper floors to unload goods hoisted by tower cranes to the corresponding floors. A common unloading platform is a device for adjusting the height of the unloading port, as disclosed in patent publication number CN219100765U.

[0003] Currently, some construction sites require a minimum fence height of 1.5 meters, with the lower edge of the unloading opening typically ranging from 0.5 to 0.8 meters. This creates safety hazards for workers moving around the unloading area, necessitating the addition of guardrails after unloading. Existing technologies, such as the protective panels disclosed in the aforementioned patent, offer limited protection, making it easy for materials or tools to spill outwards, resulting in insufficient protection. Furthermore, their assembly and disassembly are cumbersome, especially when unloading long materials. Utility model patent CN222614865U discloses a pull-out unloading platform that uses chains for protection at the unloading opening. While relatively easy to assemble and disassemble, it still suffers from insufficient protection. Therefore, the applicant proposes a construction unloading platform. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a construction unloading platform, comprising a base plate and a fence. The fence has an unloading port, and the platform further includes a protective plate installed at the unloading port. The protective plate includes a lower plate section and an upper plate section that can be folded and installed on the lower plate section. The bottom of the lower plate section is rotatably installed at the bottom of the unloading port. The upper plate section is configured to extend above the lower plate section and fold and store to the side of the lower plate section. The lower plate section can rotate between a vertical protection state and an avoidance state that rotates outward toward the fence.

[0005] Furthermore, the upper plate segment is slidably mounted vertically on the lower plate segment.

[0006] Alternatively, the upper plate segment is hinged to the lower plate segment, and the upper plate segment can be flipped and folded inside the lower plate segment.

[0007] Furthermore, the top of the upper plate section is provided with a foldable locking rod, which is configured to be folded into a storage position on the plate side of the upper plate section and unfolded into an unfolded position on the side of the upper plate section; when the locking rod is in the unfolded position, it can be fixedly connected to the edge of the discharge port.

[0008] Furthermore, the top of the upper plate section is provided with an insertion tube, and one end of the locking rod is slidably installed in the insertion tube; the fence is provided with an insertion cylinder at the edge of the discharge port, and the outer end of the locking rod can be inserted into the insertion cylinder.

[0009] Furthermore, the outer end of the locking rod is provided with a hook, which can be engaged with the insertion tube or the insertion cylinder.

[0010] Furthermore, a handle is provided at the top of the upper plate section.

[0011] Furthermore, when the upper plate segment is slidably installed vertically on the lower plate segment, the unloading platform also includes a pin. The lower end of the upper plate segment is provided with a first insertion hole, and the lower end of the lower plate segment is provided with a second insertion hole. The pin can be inserted into the first insertion hole and the second insertion hole to fix the upper plate segment and the lower plate segment. A connecting rope is provided between the pin and the handle.

[0012] Furthermore, the outer side of the fence is provided with a support base at the lower edge of the discharge port, so that the guard plate can be placed roughly flat on the support base.

[0013] Alternatively, the inner end of the locking rod is hinged to the upper plate section, the outer end of the locking rod is provided with a fixing hole, and the fence is provided with an installation hole at the edge of the unloading port corresponding to the fixing hole; the unloading platform also includes a locking rod, which can pass through the fixing hole and the installation hole.

[0014] The beneficial effect of this utility model is that, through the optimized design of the protective plate, the existing problems are effectively solved. Attached Figure Description

[0024] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0025] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0026] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0028] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0029] In this utility model, such as Figures 1 to 7 As shown, a construction unloading platform is provided, including a base plate 1 and a fence 2. The fence 2 is provided with an unloading port 3. The platform also includes a protective plate installed on the unloading port 3. The protective plate includes a lower plate section 401 and an upper plate section 402 that can be folded and installed on the lower plate section 401. The bottom of the lower plate section 401 is rotatably installed at the bottom position of the unloading port 3. The upper plate section 402 is configured to be able to unfold and extend above the lower plate section 401 and fold and store on the side of the lower plate section. The lower plate section 401 can be rotated to switch between a vertical protection state and an avoidance state that rotates outward toward the fence 2.

[0030] The unloading platform of this utility model, when the unloading port 3 is not needed, such as Figures 1 to 3 As shown, the lower plate section 401 is rotated to a vertical position, and the upper plate section 402 is unfolded to a roughly vertical position to form protection for the working space inside the fence 2. By combining the upper plate section 402 and the lower plate section 401 to form a protective plate, compared with the existing chain-like protective structure and rod-like protective structure, this utility model can provide a larger protective area, further prevent materials and tools inside the fence 2 from falling, and also provide better safety protection for workers.

[0031] When the discharge port 3 is needed, the operator can fold the upper plate section 402 and store it behind the lower plate section 401, such as... Figure 3 As shown, the guard plate is opened outward by rotating it outward. When the guard plate is needed to protect the unloading port 3, the lower plate section 401 is rotated inward to the fence 2. This utility model folds the upper plate section 402 and the lower plate section 401, so that the center of gravity of the guard plate after folding the upper plate section 402 and the lower plate section 401 is closer to its rotation axis. This reduces the rotational torque generated by overcoming the weight of the guard plate during the rotation and lowering of the guard plate (calculated based on the guard plate unfolded height of 1 meter, folded height of 0.6 meters, and lateral dimension of 1 meter, it can save about 40% of the effort), thereby reducing the difficulty of operation for operators. Moreover, the folded guard plate is smaller in size and less likely to interfere with the protective netting on the outside of the fence 2. In addition, the folded guard plate has a smaller area, and the weight of the guard plate is concentrated when in the avoidance state, making it less likely to be shaken by wind, thereby further maintaining the stability of the guard plate in use.

[0032] It should be noted that the embodiment shown in the figure is illustrated with respect to the V-shaped discharge port 3. The upper plate section 402 and the lower plate section 401 are set as rectangles. When the guard plate is in the vertical protection state, there is a gap between it and the side wall of the discharge port 3. This gap is small and has little impact on the protection of materials, tools and personnel inside the fence 2. In an optional embodiment, the width of the guard plate can also be set to be greater than the width of the discharge port 3.

[0033] In the illustrated embodiment, more specifically, regarding the structure of this utility model, the upper plate segment 402 is slidably mounted vertically on the lower plate segment 401.

[0034] For example Figures 1 to 4 As shown, the upper plate segment 402 is sleeved on the outside of the lower plate segment 401, thereby enabling the upper plate segment 402 to be slidably installed vertically on the lower plate segment 401. This allows the upper plate segment 402 to be lifted upwards and unfolded after the lower plate segment 401 rotates from the avoidance state to the protection state, reducing the difficulty of unfolding the protective plate.

[0035] The vertically slidable arrangement of the upper plate segment 402 and the lower plate segment 401 is not limited to the arrangement shown in the figure where the upper plate segment 402 is sleeved on the outside of the lower plate segment 401. In optional embodiments, other forms may also be adopted, such as the lower plate segment 401 being sleeved on the outside of the upper plate segment 402.

[0036] In alternative embodiments, such as Figure 5 As shown, a further optimization of the folding arrangement between the upper plate segment 402 and the lower plate segment 401 is that the upper plate segment 402 is hinged to the lower plate segment 401, and the upper plate segment 402 can be flipped and folded inside the lower plate segment 401.

[0037] In the illustrated embodiment, a further optimization of the structure of this utility model is that the top of the upper plate segment 402 is provided with a foldable locking rod 5. The locking rod 5 is configured to be folded into a storage position on the plate surface side of the upper plate segment 402 and unfolded into an unfolded position on the side of the upper plate segment 402; the locking rod 5 can be fixedly connected to the edge of the discharge port 3 when in the unfolded position. Figures 1 to 6 As shown, by setting the locking rod 5, when the guard plate is protecting the unloading port 3, the guard plate can be fixed at the top of the upper plate section 402 by using the locking rod 5, so that the upper and lower ends of the entire guard plate are fixed, thereby further improving the stability of the guard plate during protection.

[0038] The fixing method for the upper plate segment 402 and the lower plate segment 401 when they are unfolded to the protective state is not limited to the form shown in the figure, which is connected to the fence 2 by the locking rod 5. In an optional embodiment, a pin 10 structure can also be provided between the upper plate segment 402 and the lower plate segment 401 to be fixed by inserting the pin 10 structure after the upper plate segment 402 and the lower plate segment 401 are unfolded.

[0039] exist Figure 1 In the embodiment shown, more specifically regarding the setting of the locking rod 5, the top of the upper plate section 402 is provided with a tube 6, and one end of the locking rod 5 is slidably installed on the tube 6; the fence 2 is provided with a tube 7 at the edge of the discharge port 3, and the outer end of the locking rod 5 can be inserted into the tube 7.

[0040] like Figure 2 As shown, this allows the upper plate section 402 to be lifted upwards to the same height as the locking rod 5 and the insert 7, and the locking rod 5 can be slid to fix the locking rod 5 into the insert 7.

[0041] In the illustrated embodiment, in order to improve the connection and fixing effect between the locking rod 5 and the insert 7, a further optimization is provided in that the outer end of the locking rod 5 is provided with a hook 8, which can be engaged with the insert 6 or the insert 7.

[0042] like Figure 2 As shown, the hook 8 is welded to the outer end of the locking rod 5. The hook 8 can pass through the insert 7 and engage with the wall of the insert 7 to prevent the locking rod 5 from falling off. When the locking rod 5 is folded and retracted to the upper plate section 402 position, the hook 8 of the locking rod 5 can engage and fix it to the wall of the insert tube 6.

[0043] In the illustrated embodiment, for further ease of operation, the present invention is further optimized in that a handle 9 is provided at the top of the upper plate segment 402.

[0044] In the illustrated embodiment, a further optimization of this utility model is that, when the upper plate segment 402 is slidably mounted vertically on the lower plate segment 401, the unloading platform further includes a pin 10. The lower end of the upper plate segment 402 is provided with a first insertion hole 12, and the lower end of the lower plate segment 401 is provided with a second insertion hole 13. The pin 10 can be inserted into the first insertion hole 12 and the second insertion hole 13 to fix the upper plate segment 402 and the lower plate segment 401. A connecting rope 11 is provided between the pin 10 and the handle 9.

[0045] As shown in the figure, a pin 10 is provided so that when the upper plate section 402 and the lower plate section 401 are folded, the pin 10 can be inserted into the first insertion hole 12 and the second insertion hole 13 to prevent the upper plate section 402 and the lower plate section 401 from moving freely. A connecting rope 11 is provided to prevent the pin 10 from being lost, and also allows the operator to easily rotate the guard plate by pulling the connecting rope 11 when it needs to be rotated from the avoidance position to the protective position.

[0046] In the illustrated embodiment, specifically regarding the structure of this utility model, a support base 14 is provided on the outer side of the fence 2 at the lower edge of the discharge port 3, so that the guard plate can be placed approximately flat on the support base 14. Figure 3 As shown, the support base 14 is roughly triangular in shape. When the guard plate is in the avoidance state, it can be placed roughly horizontally on the support base 14 (the guard plate is allowed to have an angle of ±10° with the horizontal plane, which can be achieved by installing sleepers on the top of the support base 14 to support the guard plate). In this way, when the guard plate is in the avoidance state, it can receive materials and tools that leak from the discharge port 3 to the outside of the fence 2, and can also protect the internal workers. It also reduces the difficulty of rotating the guard plate to a vertical state.

[0047] In an alternative embodiment, the connection between the locking rod 5 and the upper plate segment 402 can also be configured such that the inner end of the locking rod 5 is hinged to the upper plate segment 402, the outer end of the locking rod 5 is provided with a fixing hole 15, and the fence 2 is provided with an installation hole 16 at the edge of the unloading port 3 corresponding to the fixing hole 15; the unloading platform also includes the locking rod 5, which can pass through the fixing hole 15 and the installation hole 16.

[0048] like Figure 6 As shown, the left locking rod 5 is located on the side of the upper plate section 402, and the right locking rod 5 is rotated to the side of the fence 2 and then fixed by the locking rod 5 insertion. The locking rod 5 can be made of steel bars.

[0049] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0050] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
