Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and relates to a high-safety assembled unloading platform. Background Art

[0002] An unloading platform is a commonly used facility on construction sites, mainly used for the transfer and temporary stacking of materials. The unloading platform is usually set in the middle and upper floors of a building to facilitate the transportation of building materials (such as cement, sand, gravel, steel bars, etc.) from the ground to the required floors, or for the transfer of materials between floors.

[0003] There are weight limit requirements for the transferred materials on the unloading platform. At present, the weight control of the transferred materials carried on the unloading platforms at the construction site is manually estimated, and the weight of the transferred materials cannot be accurately controlled. Most of the time, the unloading platform is filled until it is full enough before stopping. The unloading platform often overloads, and the non-standard use leads to great risks in the use of the unloading platform, with great potential safety hazards, and the safety of the staff cannot be effectively guaranteed. At the same time, most of the tops of the existing unloading platforms are in an open state, and there is a risk of building materials falling off. Content of the Utility Model

[0004] In view of the technical problems in the prior art, the utility model provides a high-safety assembled unloading platform, which includes a base, two side plates and a bottom plate. One end of the base is fixedly connected to the floor structure surface through two support legs. The two side plates are respectively fixedly connected to both sides of the base through multiple square tubes. A connecting plate is installed at the end of the base far from the floor structure surface. The bottom plate is installed on the top of the base and is located between the two side plates. The unloading platform further includes a protection mechanism, which includes two protection plates, two adjusting rods, two groups of transmission components and multiple load-bearing springs. The two protection plates are respectively hinged to the tops of the two side plates through brackets. The two adjusting rods are respectively slidably connected to the two side plates and are located between the protection plates and the side plates. The bottom of the adjusting rod is fixedly connected to the bottom plate through a transmission component and moves synchronously with the bottom plate. The multiple load-bearing springs are arranged at intervals, and one end of the load-bearing spring is fixedly connected to the bottom plate, and the other end abuts against the bottom plate. The sum of the maximum elastic forces of the multiple load-bearing springs is not greater than the maximum load of the unloading platform. When the multiple load-bearing springs are compressed to the shortest, the top of the adjusting rod retracts into the side plate, and the ends of the two protection plates away from the brackets are attached to each other. On the contrary, the top of the adjusting rod slides out of the side plate and abuts against the protection plate for attachment.

[0005] Further, the transmission component includes an L-shaped connecting rod. A through hole is provided in the middle of the base. One end of the connecting rod passes through the through hole and abuts against the bottom plate, and the other end is fixedly connected to the bottom of the adjusting rod.

[0006] Further, the protection mechanism further includes a plurality of support columns, which are fixedly installed on the base and located inside the load-bearing springs. The height of the support columns is equal to the length of the load-bearing springs when they are compressed to the shortest.

[0007] Further, a slider is fixedly installed at the top of the load-bearing spring. A chute matching the slider is provided at the bottom of the bottom plate, and the slider is slidably connected to the chute.

[0008] Further, an installation groove is formed at one end of the bottom plate close to the floor structural surface. A pull rod is slidably arranged in the installation groove, and a handle is rotatably connected to the end of the pull rod outside the installation groove.

[0009] Further, the protection mechanism further includes two tension springs. One end of each tension spring is hinged to the top of the side plate, and the other end is hinged to the protection plate, and the hinged position is located at the end of the protection plate close to the top.

[0010] Beneficial effects:

[0011] 1. In the present utility model, through the arrangement of two protection plates, two adjusting rods, two sets of transmission components and a plurality of load-bearing springs, when the materials on the unloading platform reach a certain weight, the two protection plates can be controlled to close the top of the unloading platform. On the one hand, it can remind the construction workers to avoid overloading, and on the other hand, it can also prevent the materials from falling off, effectively reducing the use risk of the unloading platform, reducing potential safety hazards, and greatly improving the safety of the staff. The specific process is as follows: when the materials are placed on the bottom plate, the bottom plate will move downward under the weight of the materials, compressing the load-bearing springs. The adjusting rods move synchronously with the bottom plate under the drive of the transmission components. As the adjusting rods move downward, the two protection plates gradually lose the support of the adjusting rods and rotate towards each other around the hinge points. When the weight of the materials reaches the sum of the maximum elastic forces of the plurality of load-bearing springs, the load-bearing springs are compressed to the shortest. At this time, the tops of the adjusting rods retract into the side plates, and the two protection plates completely close the top of the unloading platform. Since the sum of the maximum elastic forces of the plurality of load-bearing springs is not greater than the maximum load of the unloading platform, when the protection plates completely close the top of the unloading platform, the unloading platform is always within the safe load range.

[0012] 2. In the present utility model, through the arrangement of the L-shaped connecting rod, the synchronous movement of the bottom plate and the adjusting rod can be simply and conveniently realized.

[0013] 3. In the present utility model, through the arrangement of the support columns and their height limits, the linear movement of the load-bearing springs can be ensured, and at the same time, the movement displacement of the bottom plate can be limited, improving the service life of the load-bearing springs.

[0014] 4. In the present utility model, through the arrangement of the slider and the chute, the sliding of the bottom plate and the base can be facilitated, enabling the bottom plate part to disengage from the base and enter the floor structure surface during unloading, so that construction workers do not need to enter the unloading platform, further improving the safety of the staff; through the arrangement of the installation groove, the pull rod and the handle, the movement of the bottom plate can be facilitated, and at the same time, the handle and the pull rod can be conveniently retracted to avoid occupying space. Combined with the rotatable connection of the handle, the bottom plate can be supported when it moves to the floor structure surface, facilitating unloading.

[0015] 5. In the present utility model, through the arrangement of the tension spring, the opening angle of the protection plate can be restricted, preventing the two protection plates from rotating towards the mutually separated sides. At the same time, the closing speed of the protection plate can be increased, and certain buffering force can also be provided during the closing process to avoid the direct collision of the protection plate with the top of the side plate and reduce noise.

[0031] The present utility model provides a high - safety prefabricated unloading platform, such as Figures 1 to 5As shown in the figure, it includes a base 1, two side plates 2 and a bottom plate 3. One end of the base 1 is fixedly connected to the floor structural surface through two legs 4. The base 1 is formed by splicing two vertical I-beams and multiple horizontal I-beams, and is fixed by bolts and steel plates. The vertical I-beams are 16#, and the horizontal I-beams are 14#. Among them, the vertical I-beams can be integrally arranged with the legs 4 or separately arranged. The two side plates 2 are respectively fixedly connected to both sides of the base 1 through multiple square tubes 5. The cross-sectional size of the square tube 5 is 5cm * 5cm, and the length is customized according to construction needs, and is spliced and fixed to the vertical I-beam through bolts and steel plates. A connecting plate 6 is installed at one end of the base 1 away from the floor structural surface. The bottom plate 3 is installed on the top of the base 1 and is located between the two side plates 2. It also includes a protection mechanism. The protection mechanism includes two protection plates 7, two adjusting rods 8, two groups of transmission components 9 and multiple load-bearing springs 10. The two protection plates 7 are respectively hinged to the tops of the two side plates 2 through brackets 11. The two adjusting rods 8 are respectively slidably connected to the two side plates 2 and are located between the protection plate 7 and the side plate 2. To improve the stability of the protection plate 7, the adjusting rod 8 is installed in the middle of the side plate 2. When the adjusting rod 8 slides, to ensure that the protection plate 7 can rotate freely, the protection plate 7 always inclines towards the side of the adjusting rod 8. The bottom of the adjusting rod 8 is fixedly connected to the bottom plate 3 through the transmission component 9 and moves synchronously with the bottom plate 3. The multiple load-bearing springs 10 are arranged at intervals, and one end of the load-bearing spring 10 is fixedly connected to the bottom plate 3, and the other end abuts against the bottom plate 3. The sum of the maximum elastic forces of the multiple load-bearing springs 10 is not greater than the maximum load of the unloading platform. Preferably, the sum of the maximum elastic forces is slightly less than the maximum load. When the multiple load-bearing springs 10 are compressed to the shortest, the top of the adjusting rod 8 disengages from the protection plate 7 and retracts into the side plate 2. The ends of the two protection plates 7 away from the brackets 11 are fitted together. At this time, the two protection plates 7 completely enclose the top space of the unloading platform. On the contrary, the top of the adjusting rod 8 slides out of the side plate 2 and abuts against and fits with the protection plate 7. At this time, the protection plate 7 will completely open the top space of the unloading platform under the limiting and supporting action of the adjusting rod 8, facilitating loading and unloading.

[0032] In this embodiment, through the arrangement of two protective plates 7, two adjusting rods 8, two sets of transmission components 9 and multiple bearing springs 10, it is possible to control the two protective plates 7 to close the top of the unloading platform after the materials on the unloading platform reach a certain weight. On the one hand, it reminds the construction personnel to avoid overloading, and on the other hand, it can also prevent the materials from falling off, effectively reducing the use risk of the unloading platform, reducing potential safety hazards, and greatly improving the safety of the staff. The specific process is that when the materials are placed on the bottom plate 3, the bottom plate 3 will move downward under the weight of the materials, compressing the bearing springs 10. The adjusting rods 8 move synchronously with the bottom plate 3 driven by the transmission components 9. As the adjusting rods 8 move downward, the two protective plates 7 gradually lose the support of the adjusting rods 8 and rotate towards each other around the hinge points. When the weight of the materials reaches the sum of the maximum elastic forces of the multiple bearing springs 10, the bearing springs 10 are compressed to the shortest. At this time, the top of the adjusting rods 8 disengages from the protective plates 7 and retracts into the side plates 2, and the two protective plates 7 completely close the top of the unloading platform. Since the sum of the maximum elastic forces of the multiple bearing springs 10 is not greater than the maximum load-bearing capacity of the unloading platform, when the protective plates 7 completely close the top of the unloading platform, the unloading platform is always within the safe load-bearing range.

[0033] In the present utility model, preferably, as Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the transmission component 9 includes an L-shaped connecting rod. A through hole is provided in the middle of the base 1. One end of the connecting rod passes through the through hole and abuts against the bottom plate 3, and the other end is fixedly connected to the bottom of the adjusting rod 8. Specifically, the end of the short side of the connecting rod abuts against the bottom plate 3, and the end of the long side is fixedly connected to the top of the adjusting rod 8.

[0034] In this embodiment, through the arrangement of the L-shaped connecting rod, it is possible to simply and conveniently achieve the synchronous movement of the bottom plate 3 and the adjusting rod 8. In addition, the overall structure is simple, and the operation and maintenance are convenient.

[0035] In the present utility model, preferably, as Figure 3 and Figure 4 shown, the protection mechanism further includes multiple support columns 12. The support columns 12 are fixedly installed on the base 1 and are located inside the bearing springs 10. The height of the support columns 12 is equal to the length when the bearing springs 10 are compressed to the shortest.

[0036] In this embodiment, through the arrangement of the support columns 12 and the limitation of their height, it is possible to ensure the linear movement of the bearing springs 10, and at the same time, it can limit the displacement of the bottom plate 3, improving the service life of the bearing springs 10.

[0037] In the present utility model, preferably, as Figure 2 , Figure 3 , Figure 4 andFigure 5 As shown, a slider 13 is fixedly installed at the top of the bearing spring 10. A chute 14 matching the slider 13 is provided at the bottom of the bottom plate 3. The slider 13 is slidably connected to the chute 14. To reduce the number of slots of the chute 14 and improve the structural strength of the bottom plate 3, specifically, two chutes 14 can be provided. The multiple sliders 13 are divided into two groups, and the multiple sliders 13 in each group are on the same straight line. Each group of sliders 13 is slidably connected to the chute 14. Additionally, to make the multiple bearing springs 10 bear force evenly, the multiple sliders 13 in each group can be connected into one body.

[0038] In this embodiment, through the arrangement of the slider 13 and the chute 14, it is convenient for the bottom plate 3 to slide relative to the base 1. When unloading, a part of the bottom plate 3 can be separated from the base 1 and enter the floor structural surface, so that construction workers do not need to enter the unloading platform, further improving the safety of the staff.

[0039] In the present utility model, preferably, as Figure 1 、 Figure 2 and Figure 6 shown, an installation groove 15 is formed at one end of the bottom plate 3 close to the floor structural surface. A pull rod 16 is slidably arranged in the installation groove 15. One end of the pull rod 16 outside the installation groove 15 is rotatably connected to a handle 17.

[0040] In this embodiment, through the arrangement of the installation groove 15, the pull rod 16 and the handle 17, it is convenient to move the bottom plate 3. At the same time, it is convenient to retract the handle 17 and the pull rod 16 to avoid occupying space. Combining with the rotatable connection of the handle 17, it can support the bottom plate 3 when it moves to the floor structural surface, facilitating unloading. Specifically, when it is necessary to pull the bottom plate 3, the pull rod 16 can be pulled out by an appropriate length according to the actual situation, and then the bottom plate 3 can be pulled towards the floor structural surface by holding the handle 17. When the bottom plate 3 reaches the predetermined position, the handle 17 is rotated downward by 90°, so that the end of the handle 17 abuts against the floor structural surface.

[0041] In the present utility model, preferably, as Figure 1 and Figure 3 shown, the protection mechanism further includes two tension springs 18. One end of each tension spring 18 is hinged to the top of the side plate 2, and the other end is hinged to the protection plate 7, and the hinged position is at one end of the protection plate 7 close to the top.

[0042] In this embodiment, through the arrangement of the tension springs 18, the angle when the protection plate 7 is opened can be limited, preventing the two protection plates 7 from rotating towards the mutually separated sides. At the same time, it can improve the closing speed of the protection plate 7. Additionally, it can also provide a certain buffering force during the closing process to prevent the protection plate 7 from directly colliding with the top of the side plate 2 and reducing noise.

[0043] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0044] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
