Description

Technical Field

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

[0002] Material handling and unloading are frequent and critical processes during construction. As a vital transitional structure for transferring materials from vertical transport equipment to the building's interior floors, the performance of the unloading platform directly impacts construction efficiency and safety.

[0003] However, the unloading platforms currently used in construction projects still have the following problems in actual use:

[0004] Most unloading platforms used in construction projects are horizontal sliding unloading platforms. However, once they move to the unloading position, the interior is a flat structure, which cannot unload automatically. The materials need to be unloaded manually, which affects the unloading efficiency. In particular, bulk building materials need to be shoveled off one by one by manpower, which is inconvenient. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a material unloading platform for construction engineering, which effectively solves the deficiencies of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a material unloading platform for construction engineering, comprising two support beams, with several connecting crossbeams fixedly connected between the two support beams. A guide groove is formed in the center of the top surface of each of the two support beams, and a strip-shaped storage groove is formed at the center of the bottom surface of the inner wall of each guide groove. A transmission sprocket is rotatably connected to both sides of the inner wall of the strip-shaped storage groove. A transmission chain is connected to the outer walls of the two transmission sprockets. A sliding frame is mounted on the top of the two support beams, and pulleys are rotatably connected to both sides of the bottom surface of the sliding frame. Four pulleys are slidably connected to the two guide grooves respectively. Connecting plates are fixedly connected to both sides of the bottom surface of the sliding frame, and two connecting plates are respectively connected to the outer walls of the two transmission sprockets. The sliding frame is fixed with a connecting hinge on one side of its top. The sliding frame is rotatably connected to a discharge box via the connecting hinge. A guide ramp is fixedly connected to one side of the bottom of the discharge box. A support plate is fixedly connected to one side between the two support beams. Support ears are fixedly connected to both sides of the top surface of the support plate. A guide roller is rotatably connected to the top of the two support ears. The position of the guide roller corresponds to the position of the guide ramp. A drive shaft is rotatably connected to one side of the two support beams. The two ends of the drive shaft are fixedly connected to the shaft centers of two drive sprockets on the same side of the inner wall of the two strip-shaped storage slots. A reduction motor is fixedly connected to one side of any one of the two support beams. The output end of the reduction motor is fixedly connected to one end of the drive shaft.

[0007] Preferably, one of the above-mentioned solutions is that a fixed base plate is fixedly connected to one side edge of the bottom surface of the two support beams, and a diagonal brace is fixedly connected to the bottom of the two support beams at the end away from the fixed base plate, and a fixed plate is fixedly connected to the bottom end of the two diagonal braces.

[0008] The technical effect achieved by adopting the above solution is that by fixing the fixed plate to the building's exterior wall, the diagonal bracing column can support one end of the supporting beam at an angle, thereby improving the stability of the support and enhancing the load-bearing capacity.

[0009] Preferably, in any of the above schemes, the fixing plate is positioned corresponding to the center of the two supporting beams, the fixing plate is perpendicular to the two supporting beams, and a plurality of connecting beams are evenly distributed between the two supporting beams.

[0010] The technical effect achieved by adopting the above scheme is that the structural strength of the supporting beam can be improved by using several connecting beams.

[0011] Preferably, in any of the above embodiments, the length of the sliding frame is one-third of the length of the two support beams, the length of the unloading box is adapted to the length of the sliding frame, the width of the unloading box is adapted to the width of the sliding frame, and the unloading box has an open structure facing the fixed base plate.

[0012] The technical effect achieved by adopting the above solution is that the unloading box has sufficient sliding distance to be fully inserted into the building interior, and at the same time, it guides the unloading box to be fully lifted, making it convenient for the unloading box to discharge materials through the opening.

[0013] Preferably, in any of the above schemes, the length of the guide roller is less than the distance between the two connecting hinges on the left and right sides of the sliding frame, and the position of the top of the guide roller corresponds to the position of the bottom surface of the unloading box.

[0014] The technical effect achieved by adopting the above solution is that it can prevent interference between the guide roller and the connecting hinge, and at the same time, it can guide the guide roller and the guide ramp to support the unloading box.

[0015] This utility model has the following advantages:

[0016] 1. This unloading platform for construction projects uses a geared motor to drive a transmission shaft to rotate, which in turn drives a transmission chain to transport materials. This pulls the sliding frame to slide horizontally along the support beam, which in turn causes the unloading box to slide and unload materials. After the unloading box is pulled to the unloading position, the guide ramp at the bottom of the unloading box can contact the top of the guide roller, which can gradually lift the unloading box so that the opening of the unloading box is tilted, allowing the material to slide down automatically, facilitating unloading and improving unloading efficiency.

[0017] 2. This unloading platform used in construction projects is fixed to the building's exterior wall by a fixing plate, which allows the diagonal bracing column to support one end of the supporting beam, thereby improving the stability of the support and enhancing the load-bearing capacity.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figures 1 to 3As shown, a material unloading platform for construction engineering includes two support beams 1, with several connecting beams 2 fixedly connected between them. Each support beam 1 has a guide groove 6 at the center of its top surface. A strip-shaped storage groove 17 is formed at the center of the bottom surface of the inner wall of each guide groove 6. A transmission sprocket 19 is rotatably connected to both sides of the inner wall of the strip-shaped storage groove 17. A transmission chain 18 is connected to the outer walls of the two transmission sprockets 19. A sliding frame 7 is mounted on top of the two support beams 1. Pullers 8 are rotatably connected to both sides of the bottom surface of the sliding frame 7. Four pulleys 8 are slidably connected to the two guide grooves 6. Connecting plates 11 are fixedly connected to both sides of the bottom surface of the sliding frame 7. Two connecting plates 11 are fixed to the chain links on the outer walls of the two transmission sprockets 19. The top edge of the sliding frame 7... A connecting hinge 9 is fixedly connected. A sliding frame 7 is rotatably connected to a discharge box 10 via the connecting hinge 9. A guide ramp 20 is fixedly connected to one side of the bottom of the discharge box 10. A support plate 12 is fixedly connected to one side between the two support beams 1. Support ears 13 are fixedly connected to both sides of the top surface of the support plate 12. A guide roller 14 is rotatably connected to the top of the two support ears 13. The position of the guide roller 14 corresponds to the position of the guide ramp 20. A drive shaft 16 is rotatably connected to one edge of one side of the two support beams 1. The two ends of the drive shaft 16 are fixedly connected to the shaft center of two drive sprockets 19 on the same side of the inner wall of the two strip-shaped storage grooves 17. A reduction motor 15 is fixedly connected to one side of any one of the two support beams 1. The output end of the reduction motor 15 is fixedly connected to one end of the drive shaft 16.

[0024] As an optional technical solution of this utility model, a fixed base plate 5 is fixedly connected to one edge of the bottom surface of the two support beams 1, and a diagonal brace 3 is fixedly connected to the bottom of the two support beams 1 away from the fixed base plate 5. The bottom ends of the two diagonal brace 3 are fixedly connected to a fixed plate 4. By fixing the fixed plate 4 to the building exterior wall, the diagonal brace 3 can support one end of the support beam 1 at an angle, thereby improving the stability of the support and the load-bearing effect.

[0025] As an optional technical solution of this utility model, the fixed plate 4 is positioned corresponding to the center of the two support beams 1, the fixed plate 4 is perpendicular to the two support beams 1, and a number of connecting beams 2 are evenly distributed between the two support beams 1. The structural strength of the support beams 1 can be improved by the number of connecting beams 2.

[0026] As an optional technical solution of this utility model, the length of the sliding frame 7 is one-third of the length of the two support beams 1, the length of the unloading box 10 is adapted to the length of the sliding frame 7, the width of the unloading box 10 is adapted to the width of the sliding frame 7, and the unloading box 10 is open on the side facing the fixed base plate 5, so that the unloading box 10 has enough sliding distance to be completely sent into the building interior, and at the same time to guide the unloading box 10 to be fully lifted, so that the unloading box 10 can discharge materials through the opening.

[0027] As an optional technical solution of this utility model, the length of the guide roller 14 is less than the distance between the two connecting hinges 9 on the left and right sides of the sliding frame 7, and the position of the top of the guide roller 14 corresponds to the position of the bottom surface of the unloading box 10, so as to prevent the guide roller 14 from interfering with the connecting hinge 9. At the same time, the guide roller 14 and the guide ramp 20 can guide and support the unloading box 10.

[0028] This unloading platform, used in construction projects, requires the following steps for use:

[0029] 1) The transmission shaft 16 is driven to rotate by the geared motor 15, which in turn drives the transmission sprocket 19 to rotate, thereby driving the transmission chain 18 to convey, which in turn pulls the sliding frame 7 to slide horizontally along the support beam 1, thereby driving the unloading box 10 to slide and unload.

[0030] 2) After the unloading box 10 is pulled to the unloading position, the guide ramp 20 at the bottom of the unloading box 10 can be brought into contact with the top of the guide roller 14, thereby gradually lifting the unloading box 10 so that the opening of the unloading box 10 is tilted, so that the material can slide down automatically and complete the unloading.

[0031] In summary, the geared motor 15 drives the transmission shaft 16 to rotate, which in turn drives the transmission sprocket 19 to rotate, thereby driving the transmission chain 18 to convey materials. This, in turn, pulls the sliding frame 7 to slide horizontally along the support beam 1, which in turn drives the unloading box 10 to slide and unload materials. After the unloading box 10 is pulled to the unloading position, the guide ramp 20 at the bottom of the unloading box 10 can make contact with the top of the guide roller 14, thereby gradually lifting the unloading box 10 so that the opening of the unloading box 10 is tilted, allowing the material to slide down automatically, facilitating unloading and improving unloading efficiency. By fixing the fixed plate 4 to the building's exterior wall, the diagonal bracing column 3 can support one end of the support beam 1 at an angle, thereby improving the stability of the support and enhancing the load-bearing capacity.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
