Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a material unloading platform and unloading method for public building construction. Background Technology

[0002] School building construction is a critical area involving the construction and maintenance of various structures in the city, such as buildings, bridges, and public facilities. On construction sites, it is usually necessary to unload various building materials. The unloading process is a key link in the construction project, which has a direct impact on the speed and safety of the project. Tower cranes are mostly used to transport materials such as formwork and scaffolding to the construction floors.

[0003] However, tower cranes cannot directly extend into the building. In order to facilitate the transportation of materials such as formwork and scaffolding, an extended unloading platform is usually set up on the building. The materials are transferred through the unloading platform, which saves time and effort and is highly efficient. This makes the unloading platform a common temporary construction facility on construction sites.

[0004] In the existing technology, the unloading platforms used in the construction of public buildings are usually operated manually. This requires construction workers to go up to the unloading platform or cantilever to operate, which means that construction workers have to work at heights and are vulnerable to accidental injury. Manual unloading is usually not efficient enough, which may lead to slow construction progress and waste of labor costs. Summary of the Invention

[0005] The present invention addresses the problems mentioned above by designing a material unloading platform and method for public building construction, enabling mechanized unloading of building materials on the platform.

[0006] To achieve the above objectives, the present invention provides a material unloading platform for public building construction, comprising an unloading plate and a push plate. The unloading plate is fixedly connected to a fixing plate, which is installed on the foundation building by multiple sets of fastening bolts. The unloading plate is symmetrically provided with a first sliding groove and a second sliding groove. A transmission mechanism is provided in the first sliding groove. A guide plate is fixedly connected to one side of the push plate, and the guide plate is slidably inserted into the second sliding groove. The other side of the push plate is movably connected to the unloading plate through the transmission mechanism.

[0007] Furthermore, the unloading plate is also fixedly connected to a reinforcing plate, which is fixedly connected to the foundation structure by multiple sets of fastening bolts.

[0008] Furthermore, the transmission mechanism includes a drive motor, a lead screw, and a nut seat. The outer casing of the drive motor is fixedly connected to the unloading plate via a retaining ring, and the output shaft is driven to the lead screw via a gear set. The lead screw is rotatably connected to the unloading plate via a bearing seat, and the nut seat cooperates with the lead screw for transmission.

[0009] Furthermore, the gear set includes a driving gear and a driven gear, the output shaft of the drive motor is connected to the driving gear, the driven gear is sleeved on the lead screw, and the driving gear meshes with the driven gear for transmission.

[0010] Furthermore, the unloading terminal of the unloading plate is provided with a placement groove, and an auxiliary plate is hinged in the placement groove. The other side of the auxiliary plate is movably abutted against the unloading plate by a positioning plate.

[0011] Furthermore, the auxiliary plate has a storage slot adapted to the positioning plate, and a first damping bearing is provided in the storage slot. The positioning plate is rotatably connected to the first damping bearing through a limiting pin.

[0012] Furthermore, the positioning plate has a slot that is compatible with the unloading plate.

[0013] Furthermore, a second damping bearing is provided on the side of the nut seat, and a sleeve column is fixedly connected to the push plate. The sleeve column includes a movably inserted cylinder and a column. The column is rotatably connected to the second damping bearing through a support rod, and the cylinder is movably connected to the traction assembly through a vertical rod.

[0014] Furthermore, the traction assembly includes a traction rod rotatably connected to the upright, an mounting plate is fixedly installed on the unloading plate, the mounting plate has a threaded hole and a smooth hole, a limit rod is movably inserted into the smooth hole, one end of the limit rod is fixedly connected to the upright plate and the other end is movably inserted into a fixing block, the fixing block is fixedly connected to the traction rod; a fixing bolt is screwed into the upright plate, the other end of the fixing bolt is threaded to the threaded hole, a compression spring is sleeved on the surface of the limit rod, and the two ends of the compression spring are respectively fixedly connected to the mounting plate and the upright plate.

[0015] The present invention also includes a method for unloading materials from a material unloading platform used in public building construction, comprising the following steps: 1) The unloading plate is fixedly installed outside the foundation building using fixing plates and fastening bolts, and the construction materials are placed on top of the unloading plate; 2) Before unloading, the auxiliary plate in the placement slot is rotated out by the hinge, and then the positioning plate in the storage slot is rotated out. The positioning plate is used to abut against the unloading plate to fix the rotation angle of the auxiliary plate. 3) During unloading, the drive motor is started, and the output shaft transmits power to the lead screw through the gear set, driving the lead screw to rotate. The nut seat that cooperates with the lead screw moves linearly based on the lead screw, and with the cooperation of the guide plate and the slide groove two, the push plate feeds linearly with the nut seat, thereby pushing the construction material above the unloading plate. When the push plate approaches the unloading end of the unloading plate, the construction material slides down along the inclined auxiliary plate. 4) After unloading, the nut seat is moved to the opening end of the slide 1 by the transmission mechanism. At this time, the push plate is aligned with the side end face of the unloading plate. The fixing bolt is rotated to disengage the fixing bolt from the threaded hole, thereby releasing the relative fixed state between the mounting plate and the vertical plate. The vertical plate is displaced away from the mounting plate by the reverse elastic force of the compression spring. During the movement of the vertical plate, the limit rod and the fixing block are pulled, which in turn causes the vertical rod and the traction rod fixedly connected to the fixing block to rotate relative to each other. The cylinder, in conjunction with the pulling of the traction rod, causes the column to rotate based on the first damping bearing. At the same time, the column is stretched based on the cylinder. When the stretching limit of the sleeve column is reached, the worker loosens the fit between the guide plate and the slide 2. The column drives the push plate to rotate around the first damping bearing, and finally removes the push plate from the unloading plate.

[0016] In summary, the present invention has the following advantages and beneficial technical effects: 1. In use, this invention first secures the unloading plate by using a fixing plate and a reinforcing plate, allowing construction materials to be placed on the unloading plate. During unloading, the drive motor is started, and the gear set drives the nut seat to feed linearly based on the lead screw. This feeding causes the push plate to move on the unloading plate, and the displacement of the push plate pushes the construction materials off the unloading plate. This mechanical unloading method solves the problem of workers manually unloading materials while standing on the unloading plate, reducing construction risks.

[0017] 2. In this invention, the first groove is used to limit the nut seat, preventing the nut seat from rotating when the lead screw rotates. The cooperation between the guide plate and the second groove provides guidance for the push plate, increases the stress points of the push plate and the unloading plate, disperses the compressive stress applied by the push plate, and thus increases the accuracy and stability of the push plate during unloading.

[0018] 3. In this invention, the auxiliary plate extends the material feeding path, reducing the vertical impact force on the material and thus providing cushioning protection. The positioning plate can be stored in the storage groove via the first damping bearing, simultaneously filling the storage groove. Releasing the positioning plate from the unloading plate allows the auxiliary plate to rotate around the hinge and be stored in the placement groove. Attached Figure Description

The embodiments of this invention will be described in detail below with reference to the accompanying drawings: The following is in conjunction with the appendix Figures 1-10 The present invention will be further described in detail below: Example 1 like Figures 1-2As shown, this embodiment discloses a material unloading platform for public building construction, including an unloading plate 1 and a push plate 11. A fixing plate 2 and a reinforcing plate 3 are welded to the bottom of the unloading plate 1. The fixing plate 2 and the reinforcing plate 3 are fixed to the outer wall of the foundation building by multiple sets of fastening bolts. Along the moving direction of the push plate 11, the unloading plate 1 is symmetrically provided with a sliding groove 4 and a sliding groove 28 that are not completely penetrated. A transmission mechanism is provided in the sliding groove 4. A guide plate 29 is welded to one side of the push plate 11. The guide plate 29 slides into the sliding groove 28. The other side of the push plate 11 is movably connected to the unloading plate 1 through the transmission mechanism.

[0022] like Figures 5-6 As shown, the transmission mechanism includes a drive motor 6, a lead screw 5, and a nut seat 7. The outer casing of the drive motor 6 is fixedly connected to the unloading plate 1 via a retaining ring 16. The output shaft indirectly drives the lead screw 5 via a gear set. A bearing seat 18 is fixedly installed on the inner end face of the slide groove 4. The lead screw 5 is rotatably connected to the unloading plate 1 via the bearing seat 18. The nut seat 7 cooperates with the lead screw 5 for transmission. The gear set includes a driving gear 17 and a driven gear 19. The output shaft of the drive motor 6 directly drives the driving gear 17. The driven gear 19 is sleeved on the lead screw 5, and the driving gear 17 and the driven gear 19 mesh for transmission.

[0023] like Figures 3-4 As shown, the unloading terminal of the unloading plate 1 has a placement groove 20. An auxiliary plate 22 is hinged to the placement groove 20 via a hinge 21. The other side of the auxiliary plate 22 is movably abutted against the unloading plate 1 via a positioning plate 26. In this embodiment, there are two sets of positioning plates 26, which are symmetrically distributed about the auxiliary plate 22. The auxiliary plate 22 has a storage groove 23 adapted to the positioning plate 26. A first damping bearing 24 is fixedly installed in the storage groove 23. The positioning plate 26 is rotatably connected to the first damping bearing 24 via a limiting pin 25. The positioning plate 26 has a slot 27 adapted to the unloading plate 1.

[0024] like Figures 7-8 As shown, a second damping bearing 8 is fixedly installed on the side of the nut seat 7, and a sleeve column 10 is provided below the push plate 11. The sleeve column 10 includes a cylinder and a column that are movably inserted. The cylinder is fixedly connected to a limit edge, and the column is fixedly connected to a stop block. The limit edge can stop the stop block. The upper end face of the column is fixedly connected to the push plate 11, and the side end face is rotatably connected to the second damping bearing 8 through the support rod 9. The cylinder is movably connected to the traction assembly through the upright rod 12.

[0025] like Figure 6 as well as Figures 9-10As shown, the traction assembly includes a traction rod 13 that is rotatably connected to the upright rod 12. A T-shaped mounting plate 30 is welded to the outside of the chute 4 in the unloading plate 1. The mounting plate 30 has a threaded hole 31 and a smooth hole. A limit rod 15 is movably inserted into the smooth hole. One end of the limit rod 15 passes through the smooth hole and is fixedly connected to an upright plate 32, preferably welded. The upright plate 32 is elongated. A fixing block 14 is movably inserted into the other end of the limit rod 15. The traction rod 13 is welded to the side end face of the fixing block 14. A fixing bolt 33 is screwed into the upright plate 32. The fixing bolt 33 sequentially connects the threaded hole 31 of the upright plate 32 and the mounting plate 30. A compression spring 34 is sleeved on the surface of the limit rod 15. The two ends of the compression spring 34 are welded to the mounting plate 30 and the upright plate 32 respectively.

[0026] Example 2 The unloading method of a material unloading platform for public building construction according to the present invention is as follows: Step 1: By using the cooperation of fixing plate 2 and reinforcing plate 3, the unloading plate 1 is fixed to the outer wall of the foundation building, and the construction materials are placed on top of the unloading plate 1; Step 2: Before unloading, the auxiliary plate 22 stored in the placement slot 20 is rotated out by the hinge 21. After rotating to a suitable angle, the positioning plate 26 is rotated out from the storage slot 23 by the setting of the first damping bearing 24, and the slot 27 at the free end of the positioning plate 26 abuts against the side of the unloading plate 1, thereby fixing the rotation angle of the auxiliary plate 22. Step 3: During unloading, start the drive motor 6. The output shaft transmits power to the lead screw 5 through the meshing of the drive gear 17 and the driven gear 19, driving the lead screw 5 to rotate. The nut seat 7, which cooperates with the lead screw 5, moves linearly based on the lead screw 5. With the cooperation of the guide plate 29 and the slide groove 28, the push plate 11 feeds linearly with the nut seat 7, thereby pushing the construction material above the unloading plate 1. When the push plate 11 approaches the unloading end of the unloading plate 1, the construction material slides down along the inclined auxiliary plate 22 to reduce the impact of the material. Step 4: After unloading, start the transmission mechanism to move the nut seat 7 to the opening end of the slide groove 4 until the push plate 11 is aligned with the side end face of the unloading plate 1. Rotate the fixing bolt 33 to disengage it from the threaded hole 31 of the mounting plate 30, thereby releasing the relative fixed state between the mounting plate 30 and the vertical plate 32. The vertical plate 32 moves away from the mounting plate 30 under the reverse elastic force of the compression spring 34. During the displacement of the vertical plate 32, it pulls the limit rod 15 and the fixing block 14. Continue to pull the limit rod 15 until... The upright 12, which is welded and fixed to the fixed block 14, rotates relative to the traction rod 13. The cylinder, in conjunction with the pulling of the traction rod 13, causes the column to rotate based on the first damping bearing 24. At the same time, the column is stretched based on the cylinder. When the stretching limit of the sleeve column 10 is reached, the worker loosens the engagement between the guide plate 29 and the slide groove 28. There is a height difference between the push plate 11 and the top surface of the unloading plate 1, which makes it convenient for the column to drive the push plate 11 to rotate around the first damping bearing 24. Finally, the push plate 11 is removed from the unloading plate 1, thus facilitating the transfer of the unloading platform.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
