Technical Field

[0001] The utility model relates to the technical field of construction equipment, and discloses an adjustable standardized ramp for a construction elevator. Background Art

[0002] According to different situations at the construction site, when some construction elevators are installed at window openings and balcony parts, ramps need to be added for people to enter and exit the elevator and transport materials. The construction elevator equipment is mainly responsible for vertical transportation, transporting personnel and materials from the ground to the high-altitude operation area. The ramp, as an extension of the elevator, solves the problem of the entry and exit of personnel and materials when the elevator cannot directly reach specific positions (such as window openings, balconies, etc.). The two are functionally connected to jointly complete the complete transportation process from the ground to the high-altitude operation area.

[0003] Traditional construction elevator ramps are generally processed from materials such as steel pipes, fasteners, and wooden boards. The processing process of traditional construction elevator ramps is slow and the finished product effect is not good. Moreover, they cannot be recycled after use, increasing the manual demolition cost and the waste wooden boards generated during demolition will also produce construction waste. With the increasing development of construction elevator equipment and its protective accessories towards standardization and customization, it is necessary to carry out technological innovation on traditional construction elevator ramps. Content of the Utility Model

[0004] In order to overcome the deficiencies of the existing construction elevator ramp, such as slow processing and non-reusability, the utility model provides an adjustable standardized ramp for a construction elevator.

[0005] The technical solution of the utility model is as follows:

[0006] An adjustable standardized ramp for a construction elevator, used for the exit of the construction elevator, includes a ramp plate. A plurality of adjustable legs are fixedly connected under the ramp plate. The adjustable legs include a connecting pipe and an adjusting bolt.

One end of the adjusting bolt passes through the threaded hole of the adjusting nut and is inserted into the connecting pipe, and the fixing nut is tightened below the adjusting nut.

[0007] Further, in one embodiment, the thread directions of the adjusting nut and the fixing nut are opposite. When rotating in the same direction, the moving directions of the adjusting nut and the fixing nut are opposite.

[0008] Further, in one embodiment, a square gasket is welded to the bottom end of the adjusting bolt, and fixing holes are arranged on the square gasket. An expansion bolt passes through the fixing holes to fix the adjustable leg to the structural ground.

[0009] Further, in one embodiment, the ramp plate is formed by splicing a plurality of splicing plates. The splicing plate includes a keel and a checkered steel plate covering the keel. The keel is formed by welding galvanized square tubes and has a grid structure.

[0010] Further, in one embodiment, an inclined connecting gasket is welded to the top end of the connecting pipe. The connecting gasket is provided with a connecting hole, and a connecting bolt passes through the connecting hole to fix the adjustable support leg to the keel.

[0011] Further, in one embodiment, there are a plurality of connecting holes on the connecting gasket. At the splicing position of two splicing plates, one connecting bolt passes through the connecting hole on one side to fix the connecting gasket to the keel of the splicing plate on the same side, and the other connecting bolt passes through the connecting hole on the other side to fix the same connecting gasket to the keel of the other splicing plate.

[0012] Further, in one embodiment, a buffer plate is further provided between the splicing plate in contact with the structural ground and the structural ground. The buffer plate is welded to the splicing plate.

[0025] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Such as Figure 1 and Figure 2As shown in the figure, the present application provides an embodiment of an adjustable standardized ramp for a construction elevator. The adjustable standardized ramp for a construction elevator is used at the exit of the construction elevator and includes a ramp plate 100. One end of the ramp plate 100 is flush with the structural beam 1, and one end is inclined and pressed against the structural ground 2. A plurality of adjustable legs are fixedly connected under the ramp plate 100. The adjustable legs include a connecting pipe 210 and an adjusting bolt 220. One end of the connecting pipe 210 is connected to the ramp plate 100, and the other end is welded with an adjusting nut 230. A fixing nut 240 is provided on the adjusting bolt 220. One end of the adjusting bolt 220 passes through the threaded hole of the adjusting nut 230 and is inserted into the connecting pipe 210, and the fixing nut 240 is tightened below the adjusting nut 230. The adjusting bolt 220 can rotate in the adjusting nut 230, so as to adjust the length of the adjusting bolt 220 exposed outside the connecting pipe 210. The fixing nut 240 can be screwed up and down on the adjusting bolt 220. When it is tightened upward below the adjusting nut 230, the fixing nut 240 fixes the exposed length of the adjusting bolt 220 and fixes the height of the adjustable leg. The double-nut structure on the adjusting leg enables the adjustable standardized ramp for a construction elevator to have an adjustable function, and the height of the ramp can be adjusted according to the on-site situation, so as to adapt to different working conditions. It solves the problem that the original construction elevator ramp cannot be reused multiple times and saves construction costs.

[0027] Among them, the connecting pipe 210 is generally a galvanized square pipe of 40*40*2.0. The adjusting bolt 220 can directly use an M20 bolt for the leg. The production and processing are simple, and the materials are easily available and easy to manufacture.

[0028] In one embodiment, the thread directions in the adjusting nut 230 and the fixing nut 240 are opposite. When rotating in the same direction, the moving directions of the adjusting nut 230 and the fixing nut 240 are opposite. The reverse double-nut design makes it difficult for the adjusting bolt 220 to rotate under the synergistic action of the adjusting nut 230 and the fixing nut 240 when installing the adjustable leg, ensuring the stability of the height of the adjustable leg, that is, ensuring the stability of the adjustable standardized ramp for a construction elevator.

[0029] In one embodiment, a square gasket 260 is welded to the bottom end of the adjusting bolt 220. A fixing hole is provided on the square gasket 260, and an expansion bolt passes through the fixing hole to fix the adjustable leg to the structural ground 2. The square gasket 260 increases the contact area between the adjustable leg 200 and the structural ground 2, ensuring the stability of the ramp

[0030] Such as Figure 3As shown, in one embodiment, the ramp plate 100 is formed by splicing a plurality of splicing plates 110. The splicing plate 110 includes a keel 1101 and a diamond plate 1102 covering the keel 1101. The thickness of the diamond plate 1102 is 1.5 mm. The keel 1101 is formed by welding galvanized square tubes, and the specification of the galvanized square tube is also 40*40*2.0, presenting a grid structure. To prevent goods or personnel from tripping, on the splicing plate 110, the edge of the diamond plate 1102 is flush with the edge of the keel 1101 or slightly protrudes from the edge of the keel 1101. The width of the splicing plate 110 is the same as the width of the construction elevator, and the length of the splicing plate 110 is 1.5 m. Generally, the exit width of the construction elevator is also 1.5 m. In this embodiment, the splicing plate 110 is a precast plate with a length of 1.5 m and a width of 1.5 m, a standardized ramp component. By adopting standardization and improving the erection method of the construction elevator ramp, quick installation and disassembly can be realized, achieving the purpose of shortening the construction period and saving labor.

[0031] As Figure 1 and Figure 2 shown, in one embodiment, an inclined connecting gasket 250 is welded to the top end of the connecting pipe 210. The connecting gasket 250 is provided with a connecting hole, and a connecting bolt passes through the connecting hole to fix the adjustable support leg 200 to the keel 1101.

[0032] As Figure 3 shown, in one embodiment, there are eight adjustable support legs 200, which are respectively fixed at the edges of the splicing plate 110 and the center positions of the grid. There are multiple connecting holes on the connecting gasket 250. At the splicing position of two splicing plates 110, one connecting bolt passes through the connecting hole on one side to fix the connecting gasket 250 to the keel 1101 of the splicing plate 110 on the same side, and the other connecting bolt passes through the connecting hole on the other side to fix the same connecting gasket 250 to the keel 1101 of the other splicing plate 110. While realizing the splicing and fixing of two splicing plates 110 through the connecting gasket 250, the number of adjustable support legs 200 used can be reduced, the installation time of the adjustable support legs 200 can be reduced, and it is also helpful to improve the inclined flatness of the surface of the ramp plate 100.

[0033] As Figure 3 shown, in one embodiment, a buffer plate is further provided between the splicing plate 110 in contact with the structural ground 2 and the structural ground 2. The buffer plate is welded to the splicing plate 110. The width of the buffer plate remains the same as the width of the splicing plate 110, both being 1.5 m, and its length needs to be selected according to the actual working conditions.

[0034] As described above, the adjustable stereotyped ramp of the construction elevator is on the higher side, and the adjustable legs have 250mm high adjustment bolts. In order to ensure the stability of the ramp, the height of the adjustable legs on the left and right sides of the ramp plate must be strictly controlled and consistent. After the processing is completed, it is necessary to test whether the ramp has inconsistent heights on the left and right sides. If so, the height of the legs is fine-tuned until it is flat. When in use, after the processed finished product is transported to the working surface, use electric screwdrivers, wrenches and other tools to assemble the two splicing plates, eight adjustable legs, and buffer plates. Adjust the leg bolts according to the height of the structural beam on the windowsill of the working surface so that the ramp plate and the structural beam are at the same height. Finally, after checking whether the ramp is installed firmly, use expansion bolts to connect and fix the adjustable legs to the structural ground to ensure that the ramp is stable and does not slip as a whole. After the installation is completed, warning tapes can be set on both sides of the ramp to serve as a safety warning.

[0035] The utility model adopts bolt connection, which is quick to install and dismantle and easy to turn around. And it is a loose assembly process, which is convenient for transportation. Through the technical innovation of the traditional construction elevator ramp, the standardization is adopted to achieve quick installation and dismantling, so as to achieve the purpose of shortening the construction period and saving labor. The utility model construction elevator adjustable standard ramp realizes the standardization of the ramp, which is more convenient in installation and dismantling, and reduces the generation of secondary costs in the construction process. At the same time, the standard ramp has an adjustable function, and the height of the legs can be adjusted according to the on-site conditions, so as to adapt to different working conditions, and has the advantage of a wider range of applications. The standard ramp can be used for multiple turnovers to achieve the effect of environmental protection and cost saving.

[0036] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0037] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
