Description

Technical Field

[0001] This utility model relates to the field of construction unloading platform technology, specifically to an externally cantilevered temporary unloading steel platform. Background Technology

[0002] A material unloading platform is a temporary operating platform (frame) erected on a construction site for material handling. It can generally be categorized into mobile unloading platforms, cantilevered unloading platforms, and ground-mounted unloading platforms. Among these, the cantilevered unloading platform is currently the most common and frequently used unloading platform in engineering construction. Unloading platforms are used to lift materials from the ground to higher ground or move construction waste generated at higher locations to the ground, thereby reducing the labor intensity of workers and improving work efficiency.

[0003] Existing unloading platforms have some shortcomings in use. Since most existing unloading platforms use prefabricated structures, due to different construction locations, there may be a certain distance between the bottom surface of the unloading platform and the floor slab during installation, requiring the welding of steel plates. However, the welding process is time-consuming, and there is also a certain height difference between the steel plates and the floor, which causes inconvenience when loading and unloading materials and affects construction efficiency. Therefore, a device is needed to solve the above problems. Utility Model Content

A fixing nut is threaded to one end of the U-shaped frame through which the clamping block passes, and the fixing nut is in contact with the lower surface of the clamping block.

[0011] Optionally, one side of the clamping block is provided with a protruding ridge to improve stability during fixing.

[0012] Optionally, both the base plate and the extension plate are provided with a transfer mechanism. The transfer mechanism includes a slide rail, a transfer plate, and a sliding groove arranged along the extension direction of the support rod. The slide rail is fixedly connected to the upper surface of the base plate and the extension plate.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: an externally cantilevered temporary unloading steel platform, including a support rod 1 and an extension mechanism. One end of the support rod 1 is provided with a fixing frame 2. The support rod 1 is connected to the floor slab through the fixing frame 2. A base plate 3 is fixedly connected to the upper surface of the support rod 1.

[0023] The expansion mechanism includes an expansion plate 4 and a positioning mechanism. There are multiple expansion plates 4. The expansion plates 4 are detachably connected to one side of the base plate 3. The expansion plates 4 are spliced ​​together by the positioning mechanism.

[0024] One end of the extension plate 4 is connected to the end plate 15 via a positioning mechanism. One end of the end plate 15 is connected to the flip plate 16 via a pivot. The side of the flip plate 16 away from the pivot is supported on the edge of the floor slab, so that the flip plate 16 forms an inclined transition between the end plate 15 and the floor slab.

[0025] Support rod 1 supports the base plate 3 above. Support rod 1 is fixed to the floor slab by fixing frame 2. Extension plate 4 can be spliced ​​on the base plate 3 in sequence and positioned by positioning mechanism to shorten the time required to install extension plate 4 and improve installation efficiency. End plate 15 can be installed on one side of extension plate 4. At the same time, a flip-up flap 16 is installed on one side of the installation plate. The flap 16 can be set at an angle on one side of end plate 15 so that end plate 15 and floor slab form an angle, which facilitates the transfer of materials from floor slab to base plate 3 and reduces the impact of height difference.

[0026] In this embodiment, as a preferred option, the positioning mechanism includes a positioning pin 8 and a positioning hole 9. The positioning hole 9 is formed on the surface of the expansion plate 4 and the base plate 3. The positioning pin 8 is inserted into the positioning hole 9 to fix the expansion plate 4 and the base plate 3.

[0027] After installing the expansion plate 4 onto the base plate 3, align the mounting plate with the positioning holes 9 on the base plate 3. Insert the positioning pin 8 into the positioning holes 9 to fix the expansion plate 4 and the base plate 3 together. When disassembling, simply pull out the positioning pin 8 to separate the expansion plate 4 from the base plate 3, thus improving the efficiency of disassembly and installation.

[0028] In this embodiment, as a preferred option, the support rod 1 is further provided with a clamping mechanism to assist in fixing the support rod 1. The clamping mechanism includes a clamping block 10, a U-shaped frame 11 and a positioning groove 12. The positioning groove 12 is opened on the upper surface of the support rod 1. The U-shaped frame 11 is located inside the positioning groove 12 and the bottom of the U-shaped frame 11 passes through the clamping block 10. A fixing nut 13 is threaded to one end of the U-shaped frame 11 through which the clamping block 10 passes. The fixing nut 13 fits against the lower surface of the clamping block 10. A protruding ridge 14 is provided on one side of the clamping block 10 to improve the stability during fixing.

[0029] The clamping block 10 is triangular. After the support rod 1 is fixed to the floor slab, the clamping block 10 can press against the side of the floor slab, forming a triangle with the support rod 1, which improves the overall strength of the support rod 1 and reduces the possibility of deformation. The U-shaped frame 11 can be inserted into the positioning groove 12 from top to bottom. The U-shaped frame 11, together with the fixing nut 13, can fix the position of the clamping block 10. The protruding ridge 14 can press against the side wall of the floor slab, increasing the friction between it and the floor slab, thereby improving the strength.

[0030] In this embodiment, as a preferred option, both the base plate 3 and the extension plate 4 are provided with a transfer mechanism. The transfer mechanism includes a slide rail 5, a transfer plate 6 and a sliding groove 7 arranged along the extension direction of the support rod 1. The slide rail 5 is fixedly connected to the upper surface of the base plate 3 and the extension plate 4. The sliding groove 7 is opened on the lower surface of the transfer plate 6 and is slidably connected to the slide rail 5 so that the transfer plate 6 slides along the direction of the slide rail 5.

[0031] The transfer plate 6 can slide on the slide rail 5. After the material is hoisted onto the transfer plate 6, the transfer plate 6 can be pulled directly off the base plate 3, reducing the time workers spend on the base plate 3 and improving the safety of the unloading process. When loading materials, the sliding groove 7 at the bottom of the transfer plate 6 is aligned with the slide rail 5, and the transfer plate 6 is moved to the base plate 3 for the next material hoisting.

[0032] In this embodiment, as a preferred option, there are multiple flaps 16 that can be flipped individually to avoid the support rod 1.

[0033] There are multiple flaps 16, and the number of flaps 16 that flip down can be adjusted according to the spacing between the support rods 1 in order to avoid the support rods 1.

[0034] In this embodiment, as a preferred option, a vertical rod 17 is fixedly connected to the outside of the upper surface of the base plate 3, and a baffle 18 is fixedly connected to the outside of the vertical rod 17. A drainage hole 19 is provided at the bottom of the baffle 18.

[0035] The upright 17 is fixed to the support rod 1, and the baffle 18 is fixed to the outside of the upright 17, enclosing the outside of the base plate 3 to improve the safety of the construction process. The drainage hole 19 at the bottom can drain the rainwater and other liquids remaining on the surface of the base plate 3, reducing the liquid residue on the surface of the base plate 3 to prevent slippage and improve safety.

[0036] In this invention, the working steps of the device are as follows:

[0037] 1. Install the U-shaped frame 11 in the positioning groove 12, use nuts to fix the clamping block 10 to the bottom of the support rod 1, adjust the position of the support rod 1 so that the clamping block 10 fits against the side of the floor slab, and use the fixing bracket 2 to fix the position of the support rod 1 at one end;

[0038] 2. Install the extension plate 4 on one side of the base plate 3, ensuring that the gap between the base plate 3 and the floor slab is covered. Then install the end plate 15 on the last extension plate 4 and use the positioning pin 8 to fix the base plate 3 and the extension plate 4, and the extension plate 4 and the end plate 15.

[0039] 3. Hoist the materials onto the transfer plate 6, and have the workers drag the transfer plate 6 directly off the base plate 3 and onto the floor slab before unloading. After unloading, slide the transfer plate 6 back onto the base plate 3.

[0040] 4. When disassembling, pull the positioning pin 8 out of the positioning hole 9, then remove the end plate 15 and the extension plate 4. After removing the fixing bracket 2, the support rod 1 can be moved away.

[0041] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
