[0001] This utility model relates to the field of construction engineering, and in particular to a material unloading platform for construction engineering. Background Technology

[0002] Construction engineering refers to the physical engineering project formed through the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. During construction, unloading platforms are needed. These platforms are temporary workbenches and scaffolds commonly erected on construction sites, generally used for material handling.

[0003] A search revealed Chinese Patent Publication No. CN222501116U, which discloses an unloading platform for construction engineering, comprising a main body of the device, a receiving box installed on one side of the main body, a motor installed inside the receiving box, an electric wire connected to one side of the motor, a roller in the middle of the main body of the device, an unloading plate installed in front of the roller, a sensing plate installed at the lower end of the unloading plate, and support rods installed on both sides of the main body of the device.

[0004] The aforementioned patented unloading platform design for construction engineering features multifunctionality, ease of operation, high safety, strong adjustability, good stability, strong expandability, easy maintenance, and space saving. However, the construction engineering unloading platform is a fixed structure, and its size and length are predetermined and non-adjustable. In some large-scale construction projects, due to the wide construction area, the unloading platform needs to be able to extend to a more distant location for more convenient unloading and transportation of materials. Fixed unloading platforms cannot be flexibly adjusted according to actual needs, which brings many inconveniences to construction operations and may even affect the construction progress. Therefore, a construction engineering unloading platform is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a material unloading platform for construction projects, which aims to solve the problem in the prior art that "fixed unloading platforms cannot be flexibly adjusted according to actual needs".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a material unloading platform for construction projects, comprising an unloading platform, an extension mechanism provided inside the unloading platform, the extension mechanism including a stepper motor, the stepper motor being fixedly installed inside the unloading platform, a bidirectional screw fixedly connected to the right side of the output shaft of the stepper motor, the end of the bidirectional screw away from the stepper motor being rotatably mounted on the inner wall of the unloading platform, a nut block being fitted onto the surface of the bidirectional screw, a connecting rod being hinged to the surface of the nut block, an extension plate being hinged to the end of the connecting rod away from the nut block, the extension plate being slidably connected to the inner wall of the unloading platform, and a cleaning mechanism being provided on the top of the extension plate.

[0007] As a further description of the above technical solution:

[0008] The cleaning mechanism includes a rack, which is fixedly mounted on the top of the extension plate.

[0009] As a further description of the above technical solution:

[0010] The cleaning mechanism also includes a rotating rod, which is rotatably mounted on the inner wall of the unloading platform. A gear is fixedly connected to the outer wall of the rotating rod, and the gear meshes with a rack.

[0011] As a further description of the above technical solution:

[0012] The cleaning mechanism also includes a rotating shaft, which is rotatably mounted on the inner wall of the unloading platform. A second gear is fixedly connected to the outer wall of the rotating shaft. The first gear and the second gear mesh, and the second gear and the rack have no contact relationship.

[0013] As a further description of the above technical solution:

[0014] The cleaning mechanism also includes a cleaning roller, which is fixedly connected to the outer wall of the rotating shaft, and the bottom of the cleaning roller is in contact with the top of the extension plate.

[0015] As a further description of the above technical solution:

[0016] The surface of the extension plate is fixedly connected with a ramp.

[0017] As a further description of the above technical solution:

[0018] The unloading platform is fixedly connected to support frames on both the left and right sides, and diagonal rods are fixedly connected to the surface of the support frames.

[0019] As a further description of the above technical solution:

[0020] The top of the unloading platform is fixedly connected to a guardrail.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the stepper motor drives the bidirectional screw to rotate, causing the nut block to move linearly. When the nut block moves, the connecting rod will change angle, thereby pushing the extension plate to slide outward along the inner wall of the unloading platform, thus extending the length of the unloading platform. This allows for flexible adjustment according to actual needs, adapting to different construction scenarios and improving adaptability.

[0023] 2. In this utility model, the rack at the top of the extension plate moves together with the extension plate, causing the cleaning roller fixed on the outer wall of the rotating shaft to rotate. The bottom of the cleaning roller contacts the top of the extension plate, thereby cleaning the surface of the extension plate and reducing the possibility of dirt and impurities entering the unloading platform.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 This utility model provides an embodiment of a material unloading platform for construction projects, comprising an unloading platform 1, an extension mechanism 14 internally configured within the unloading platform 1, and a stepper motor 2. The stepper motor 2 can precisely control the rotation angle of its output shaft, achieving high control accuracy. The stepper motor 2 is fixedly installed inside the unloading platform 1. A bidirectional screw 3 is fixedly connected to the right side of the output shaft of the stepper motor 2. The end of the bidirectional screw 3 away from the stepper motor 2 is rotatably mounted on the inner wall of the unloading platform 1.

[0032] Reference Figure 1 , Figure 2A nut block 4 is fitted onto the surface of the bidirectional screw 3. A connecting rod 5 is hinged to the surface of the nut block 4. An extension plate 6, which extends the length of the unloading platform 1, is hinged to the end of the connecting rod 5 away from the nut block 4, facilitating personnel stepping on it. A ramp 16 is fixedly connected to the surface of the extension plate 6. The top of the ramp 16 has anti-slip textures to increase friction and improve the stability and safety of personnel getting on and off the vehicle. The extension plate 6 is slidably connected to the inner wall of the unloading platform 1. A cleaning mechanism 15 is installed on the top of the extension plate 6. Support frames 17 are fixedly connected to the left and right sides of the unloading platform 1. Diagonal bars 18 are fixedly connected to the surface of the support frames 17. The support frames 17 on the left and right sides of the unloading platform 1 and the diagonal bars 18 fixedly connected to the surface of the support frames 17 provide a stable support structure for the entire unloading platform 1. The guardrail 19 at the top ensures the safety of personnel operating on the unloading platform 1. The top of the unloading platform 1 is fixedly connected to the guardrail 19.

[0033] Reference Figure 2 - Figure 4 The cleaning mechanism 15 includes a rack 8, which is fixedly installed on the top of the extension plate 6. The cleaning mechanism 15 also includes a rotating rod 10, which is rotatably installed on the inner wall of the unloading platform 1. A gear 9 is fixedly connected to the outer wall of the rotating rod 10, and the gear 9 meshes with the rack 8.

[0034] Reference Figure 2 - Figure 4 The cleaning mechanism 15 also includes a rotating shaft 12. The rotating rod 10 and the rotating shaft 12 are on the same horizontal plane. The rotating shaft 12 is rotatably mounted on the inner wall of the unloading platform 1. A gear 2 11 is fixedly connected to the outer wall of the rotating shaft 12. Gear 1 9 and gear 2 11 mesh. The diameter of gear 1 9 is larger than the diameter of gear 2 11, so that gear 2 11 and rack 8 have no contact relationship. The cleaning mechanism 15 also includes a cleaning roller 13 that can clean the surface of the extension plate 6, reducing the possibility of dirt and impurities entering the interior of the unloading platform 1. Through the cooperation of rack 8, gear 1 9 and gear 2 11, the tangential direction of the bottom of the cleaning roller 13 during rotation is opposite to the displacement direction of the extension plate 6. The cleaning roller 13 is fixedly connected to the outer wall of the rotating shaft 12, and the bottom of the cleaning roller 13 contacts the top of the extension plate 6.

[0035] Working principle: During use, the stepper motor 2 drives the bidirectional screw 3 to rotate, causing the nut block 4 to move linearly along the axial direction of the bidirectional screw 3 as the screw 3 rotates. When the nut block 4 moves, the connecting rod 5 will change angle, thereby pushing the extension plate 6 to slide outward along the inner wall of the unloading platform 1, thus extending the length of the unloading platform 1. The ramp 16 fixedly connected to the surface of the extension plate 6 facilitates personnel stepping on it, and the anti-slip texture set on the top of the ramp 16 can increase friction and improve the stability and safety of personnel getting on and off the vehicle.

[0036] As the extension plate 6 slides outward, the cleaning mechanism 15 works synchronously. The rack 8, which is fixedly installed on the top of the extension plate 6, moves together with the extension plate 6. The movement of the rack 8 will drive the first gear 9 to rotate, and the rotation of the first gear 9 will drive the second gear 11 to rotate, thereby causing the cleaning roller 13, which is fixed on the outer wall of the rotating shaft 12, to rotate. The tangential direction of the bottom of the cleaning roller 13 when it rotates is opposite to the displacement direction of the extension plate 6. The bottom of the cleaning roller 13 contacts the top of the extension plate 6, thereby cleaning the surface of the extension plate 6 and reducing the possibility of dirt and impurities entering the unloading platform 1.

[0037] When it is not necessary to extend the length of the unloading platform 1, the stepper motor 2 is started in reverse, the bidirectional screw 3 rotates in reverse, the nut block 4 moves in reverse, and the connecting rod 5 pulls the extension plate 6 back into the unloading platform 1. At the same time, the cleaning mechanism 15 will clean the surface of the extension plate 6 again.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
