Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a public building construction unloading platform and unloading method. BACKGROUND

[0002] School building construction is a key field involving the construction and maintenance of various structures in urban areas, such as buildings, bridges, public facilities, etc. On the construction site, it is often necessary to unload various building materials, and the unloading process is a key link in building engineering, which has a direct impact on the speed and safety of engineering progress. Tower cranes are usually used to transport materials such as formwork and pipe racks to the construction floor.

[0003] However, the tower crane cannot directly extend into the building. In order to facilitate the transportation of materials such as formwork and pipe racks, an external unloading platform is generally set up on the building, which transfers materials through the unloading platform, saving time and effort, and is efficient, making the unloading platform a common temporary construction facility in building construction sites.

[0004] In the prior art, the existing public building construction unloading platform is usually operated by traditional manual methods, which requires construction personnel to operate on the unloading platform or cantilever plate, so that the construction personnel must work at a high place, which is prone to accidental injury. Manual unloading is usually not efficient enough, which may cause slow construction progress and waste labor costs. SUMMARY

[0005] The present application is designed to address the above-mentioned problems, and a public building construction unloading platform and unloading method are designed to achieve mechanized unloading of building materials on the platform.

[0006] To achieve the above-mentioned purpose, the present application provides a public building construction unloading platform, which comprises an unloading plate and a push plate, the unloading plate is fixedly connected with a fixed plate, the fixed plate is installed on the foundation building through a plurality of fastening bolts, the unloading plate is symmetrically provided with a sliding groove one and a sliding groove two, the sliding groove one is provided with a transmission mechanism, the push plate is fixedly connected with a guide plate on one side, the guide plate is slidingly inserted into the sliding groove two, and the push plate is movably connected with the unloading plate through a transmission mechanism on the other side.

[0007] Further, the unloading plate is further fixedly connected with a reinforcing plate, and the reinforcing plate is fixedly connected with the foundation building through a plurality of fastening bolts.

[0008] Further, the transmission mechanism comprises a drive motor, a lead screw and a nut seat, the drive motor is fixedly connected with the unloading plate through a fixed ring, and the output shaft is drivingly connected with the lead screw through a gear set, the lead screw is rotatably connected with the unloading plate through a bearing seat, and the nut seat is drivingly connected with the lead screw.

[0009] Furthermore, the gear set includes a driving gear and a driven gear, the output shaft of the driving motor is drivingly connected to the driving gear, the screw rod outer sleeve is provided with the driven gear, and the driving gear and the driven gear are meshed for transmission.

[0010] Furthermore, a placement slot is provided at the unloading terminal of the unloading plate, an auxiliary plate is hingedly installed in the placement slot, and the other side of the auxiliary plate is movably abutted against the unloading plate through a positioning card.

[0011] Furthermore, the auxiliary plate is provided with a receiving groove adapted to the positioning clamping plate, a first damping bearing is provided in the receiving groove, and the positioning clamping plate is rotatably connected to the first damping bearing via a limit pin.

[0012] Furthermore, the positioning card plate is provided with a card slot adapted to the unloading plate.

[0013] Furthermore, a second damping bearing is provided on the side of the nut seat, and the push plate is fixedly connected to a sleeve column. The sleeve column includes a movably plugged 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 vertical rod, the unloading plate is fixedly installed with a mounting plate, the mounting plate is provided with a threaded hole and a light hole, a limit rod is movably inserted in the light hole, one end of the limit rod is fixedly connected to the vertical plate and the other end is movably inserted with a fixed block, the fixed block is fixedly connected to the traction rod; a fixing bolt is threaded in the vertical plate, the other end of the fixing bolt is threadedly connected 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 vertical plate.

[0015] The present invention also includes a method for unloading a material unloading platform for public building construction, comprising the following steps: 1) Use the fixing plate and fastening bolts to fix the unloading plate outside the foundation building, and place the construction materials 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 card in the storage slot is rotated out, and the positioning card is used to abut the unloading plate to fix the rotation angle of the auxiliary plate; 3) When unloading, the drive motor is started, and the output shaft transmits power to the screw through the gear set, driving the screw to rotate. The nut seat that cooperates with the screw makes a linear motion based on the screw. Under the cooperation of the guide plate and the second slide, the push plate feeds linearly with the nut seat, thereby pushing the construction materials above the unloading plate. When the push plate approaches the unloading terminal of the unloading plate, the construction materials slide down along the inclined auxiliary plate; 4) After unloading, the transmission mechanism is used to move the nut seat to the open end of the slide groove 1. At this time, the push plate is aligned with the side end face of the unloading plate, and the fixing bolt is rotated to make the fixing bolt disengage from the threaded hole, thereby releasing the relative fixed state of the mounting plate and the vertical plate. The vertical plate is displaced in the direction 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 fixed block are pulled, and then the vertical rod and the traction rod fixedly connected to the fixed block produce relative rotation. The cylinder cooperates with the pulling of the traction rod to make the column 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 matching state of the guide plate and the slide groove 2, and the column drives the push plate to flip around the first damping bearing, and finally moves the push plate out of the unloading plate.

[0016] In summary, the present invention has the following advantages and beneficial technical effects: 1. When using the present invention, the unloading plate is first fixed and installed by cooperating with the fixing plate and the reinforcing plate, and construction materials can be placed on the unloading plate. When unloading, the drive motor is started, and the gear train drives the nut holder to linearly feed the lead screw. This feed drives 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 eliminates the problem of workers manually unloading materials while standing on the unloading plate, reducing construction risks.

[0017] 2. In this invention, the first chute serves to limit the nut seat, preventing it from rotating with the screw. The cooperation between the guide plate and the second chute provides guidance for the push plate, increases the stress points between the push plate and the discharge plate, and disperses the compressive stress applied by the push plate, thereby increasing the accuracy and stability of the push plate discharge process.

[0018] 3. The auxiliary plate in this invention extends the material discharge path, reducing vertical impact forces on the materials and providing cushioning protection. The positioning plate can be stored in the receiving slot via the first damping bearing, while the slot is being filled. Once the positioning plate is released from contact with the discharge plate, the auxiliary plate can be pivoted about the hinge and stored in the placement slot. BRIEF DESCRIPTION OF THE DRAWINGS
