Description

Technical Field

[0001] The invention relates to the technical field of floor-standing unloading platforms, in particular to a floor-standing unloading platform dedicated to factory buildings. Background Art

[0002] The unloading platform used in construction engineering is a variety of temporary operating tables and operating frames often set up at the construction site. It is generally used for the turnover of materials and is divided into mobile unloading platforms, floor-standing unloading platforms, and cantilevered unloading platforms. In factory building construction, due to the low floors, floor-standing unloading platforms are generally used. In the actual operation process, workers lift the materials by crane and drop them onto the unloading platform on the high floor. At this time, the unloading platform will carry the materials and transport the materials from the outside of the building to the inside of the stairs, so that the materials can be transported to the construction site. The function of the unloading platform is to immediately complete the material acceptance work outside the building and the unloading work of the materials inside the building.

[0003] At present, floor-standing unloading platforms are set up in factory buildings to facilitate the transportation of external materials to high floors. During the unloading process through the unloading platform, since the floor-standing unloading platform is located outside the building and the bottom is only supported by a steel pipe bracket, when workers enter the unloading platform to take the workpieces, if the unloading platform collapses or objects fall from a high altitude, it will greatly endanger the personal safety of the workers.

[0004] On the other hand, the patent with the search announcement number CN115434522B discloses a retractable cantilevered unloading platform. When the unloading platform is pushed to the appropriate position, the limit switch is turned to make the limiter and the limit block engage and lock, thereby completely fixing the unloading platform on the I-beam. However, it is difficult for the current unloading platform to carry out unloading work continuously. After the unloading platform transports the material to the unloading station, if the workers do not clean up the material on the unloading area in time, the material will not be able to be unloaded the next time the unloading platform transports the material, resulting in the unloading platform being unable to carry out multiple unloading operations, which reduces the unloading work efficiency. To this end, we provide a floor-standing unloading platform dedicated to factory buildings to solve the above problems. Summary of the invention

The top ends of the four telescopic springs 1 are respectively fixed to the four L-shaped plates, and the four telescopic springs 1 are respectively sleeved on the outer surfaces of the four sliding bars 1. When the top plate no longer squeezes the pressure bar, the pressure bar will be reset by the spring tension of the telescopic spring 1, so that the two box doors are close together and closed, and then the electric rail is controlled to move the empty loading and unloading box to the external base, waiting for loading of building materials.

[0016] Compared with the existing technology, the floor-standing unloading platform for plant buildings has the following beneficial effects: 1. The present invention is provided with a conveying mechanism and a rotation mechanism. After the loading and unloading box unloads the building materials onto the turnover box on one side, the connecting frame will lift the loading and unloading box through the unloading mechanisms on both sides. While the connecting frame drives the top pressure column to rise, the top pressure column will rotate 180 degrees through the oblique groove top pressure rotating column, so that the turnover box on this side is rotated to the ramp platform, and the workers can pick up the building materials, and the turnover box on the other side will rotate to the bottom of the loading and unloading box, so that the connecting frame descends to drive the loading and unloading box to fall and reset, and move the empty loading and unloading box to the external base to wait for loading of building materials. The device separates the working area for workers to pick up materials and the area for loading building materials without affecting each other, so that the loading operation and the picking operation can be carried out simultaneously. Through this rotation method, multiple unloading operations can be carried out continuously, thereby improving the unloading efficiency of the device.

[0017] 2. The present invention is provided with a conveying mechanism and a loading mechanism. Since the cylindrical base is installed inside the floor, when the building materials are unloaded into the loading and unloading box and moved to the turnover box, the top plates on both sides are controlled to press the two pressure rods respectively, so that the movable plate presses the two hinged rods to make the two box doors move away from each other, so that the building materials in the loading and unloading box are dumped into the turnover box, and then the turnover box is rotated to the ramp platform, and the workers can pick up the building materials inside the floor, thereby improving the safety of the workers when picking up and unloading, and reducing safety hazards.

When the top pressure column 504 falls along the vertical groove 512, the upper surface of the blocking block A518 is an inclined surface, and the top pressure column 504 will pass through the inclined surface of the blocking block A518 and squeeze the blocking block A518, so that the blocking block A518 does not block the falling trajectory of the top pressure column 504. After being compressed, the blocking block A518 will be reset by the spring tension of the telescopic spring three 519.

A telescopic spring 2 516 is arranged inside the sleeve 514. The two ends of the telescopic spring 2 516 are respectively fixed to the sleeve 514 and the blocking block B515. When the top pressure column 504 falls from the top, it will be blocked by the two blocking blocks B515 to prevent the top pressure column 504 from falling from the top along the oblique groove 513, so that the top pressure column 504 passes through the vertical groove 512 every time it falls from the top, and when the top pressure column 504 rises along the oblique groove 513, the two blocking blocks B515 do not block the rising trajectory of the top pressure column 504.

[0033] Working principle: When in use, the electric track 203 is controlled to drive the fixed frame 313 to move, so that the loading and unloading box 301 moves to the top of the external base 201, such as Figure 3 As shown, the external building materials are loaded into the loading and unloading box 301 by a crane. After the loading is completed, the electric track 203 is controlled to move the loading and unloading box 301 to the far right, so that the loading and unloading box 301 is located directly above the turnover box 206.

[0034] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the second motor 507 is controlled to drive the second threaded tube 508 to rotate, so that the second threaded rod 505 drives the connecting frame 502 to move downward through the second fixed plate 503. The connecting frame 502 moves downward so that the two unloading mechanisms 4 are respectively located on both sides of the loading and unloading box 301. The electric telescopic rod 415 is controlled to drive the mobile frame 401 to approach the loading and unloading box 301, so that the docking block 402 on the mobile frame 401 is plugged with the two limit pins 312, and the loading and unloading box 301 is limited and fixed. Then the motor 1 412 is controlled to drive the rotating tube 411 to rotate, and the rotating tube 411 rotates. The two slide bars 414 drive the rotating shaft 413 to rotate, and the rotation of the rotating shaft 413 drives the threaded tube 1 405 to rotate through the meshing of the bevel gear 2 409 and the bevel gear 1 408, so that the threaded rod 1 404 drives the top plate 403 to move downward, and the downward movement of the top plate 403 will press the pressure rod 306. The pressure rods 306 on both sides descend at the same time, which will drive the two movable plates 308 to descend. When the movable plates 308 descend, the two box doors 310 are driven away from each other through the two hinged rods 309, so that the building materials in the loading and unloading box 301 are dumped into the turnover box 206.

[0035] After the unloading of the building materials in the loading and unloading box 301 is completed, the control motor 2 507 is started to make the threaded rod 2 505 drive the connecting frame 502 to move upward. Since the docking blocks 402 on both sides limit the loading and unloading box 301 at this time, the upward movement of the connecting frame 502 will drive the loading and unloading box 301 away from the rotating disk 204. When the connecting frame 502 rises, it also drives the top pressure column 504 to rise. The top pressure column 504 will press the rotating column 510 through the oblique groove 513 to rotate 180 degrees, so that the turnover box 206 close to the side of the external base 201 is rotated to the ramp platform 205, so that the workers can pick up the building materials, and the turnover box 206 originally close to the side of the ramp platform 205 will rotate to the bottom of the loading and unloading box 301, and the motor 2 is controlled again. 507 causes the connecting frame 502 to descend, driving the loading and unloading box 301 to fall and reset, and controls the motor 412 to drive the rotating tube 411 to rotate in the opposite direction, so that the top plate 403 no longer squeezes the pressure rod 306, and the pressure rod 306 will be reset by the spring tension of the telescopic spring 307, so that the two box doors 310 are closed, and then the electric track 203 is controlled to move the empty loading and unloading box 301 to the external base 201 to wait for loading of building materials. The device separates the working area for workers to pick up materials and the area for loading building materials without affecting each other, so that the loading operation and the picking operation can be carried out at the same time, and the above operation process is repeated. Through this rotation method, multiple unloading operations can be carried out continuously, thereby improving the unloading efficiency of the device.
