Description

Technical Field

[0001] The utility model belongs to the technical field of construction elevators, and in particular relates to a construction elevator with a protection mechanism. Background Art

[0002] At present, with the rapid development of modern construction industry, the continuous updating of construction methods and the continuous optimization of construction technology, vertical transportation equipment is also constantly developing. Among them, construction elevators or material hoists are now indispensable tools for vertical transportation. Conventional elevators leave a certain distance from the building structure during installation. In order to prevent materials or construction personnel from falling from the gap between the building and the elevator, the gap between the building and the elevator will be connected through a protective plate, thereby achieving a protective effect.

[0003] A construction elevator protection device with a patent announcement number of CN218403205U in the prior art includes a baffle, which is arranged on the outer side of the door panel of the elevator, and the lower end of the baffle is hinged to the body of the elevator through a hinge shaft. A linkage rod is arranged between the baffle and the door panel of the elevator, and the two ends of the linkage rod are respectively connected to the baffle and the door panel of the elevator through a ball joint. The opening of the door panel of the elevator drives the baffle to rotate from an upright state to a flat state, and the closing of the door panel of the elevator drives the baffle to rotate from a flat state to an upright state; it has the function of reducing small particles in the process of transporting materials. The effect of materials falling from the gap between the elevator body and the building is improved, but there are still the following shortcomings in actual use: when construction workers use a feeding dump truck to transport materials, the feeding dump truck is not easy to fix in the elevator, and it is easy to move and cause a collision with the elevator, affecting the safe operation of the elevator. Construction workers usually have to manually support and limit it for a long time, which increases the work intensity of construction workers, and most of the protective plates do not have interception plates on both sides. When the construction workers push the feeding dump truck through the protective plate and it shakes slightly, the splashed materials are easy to hit the ground, causing casualties to the workers on the ground.

[0004] Therefore, a construction elevator with a protective mechanism is needed to solve the problem in the prior art that when using an elevator to transport materials, workers need to manually fix the material cart for a long time, and the splashed materials are easy to hit the ground and cause casualties.

[0024] Further as Figure 2 As shown, it is worth explaining in detail that the power mechanism 6 includes a rotating shaft 61 and a fixed rod 65, the outer walls on both sides of the rotating shaft 61 are rotatably connected to the inner walls on both sides of the elevator body 1 respectively, and the outer surfaces of the rotating shaft 61 are tightly sleeved with take-up rollers 62, and the outer surfaces of the two take-up rollers 62 are wound with cables 63, and the outer surface of the rotating shaft 61 is tightly sleeved with a driven gear 64, the top surface of the fixed rod 65 is fixedly connected to the inner wall of the top surface of the elevator body 1, and the bottom surface of the fixed rod 65 is fixedly connected to the second motor 66, and the output end of the second motor 66 is coaxially fixedly connected with a driving gear 67 meshing with the driven gear 64.

[0025] Further as Figure 1 and Figure 4 As shown, it is worth explaining in detail that two parallel sliding rails 7 are provided on the outer walls on both sides of the elevator body 1, and each sliding rail 7 is slidably connected to a track wheel 8. The bottom of the outer walls on both sides of the front lifting door 2 and the rear lifting door 3 are fixedly connected to connecting plates 9, and the four connecting plates 9 are fixedly connected to the four track wheels 8 respectively.

[0026] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that observation windows 10 are embedded in the outer walls at both ends of the operating room 4, and three hinges 11 distributed in parallel are installed on the inner wall of the bottom surface of the elevator body 1, and the movable ends of the three hinges 11 are fixedly connected to the outer wall of one end of the protective plate 51.

[0030] When the elevator body 1 runs to the target height, the operator controls the rear lifting door 3 to rise upward, and then reversely starts the first motor 57 so that the two clamping plates 55 release the limit on the feeding dump truck, and then starts the second motor 66 to drive the driving gear 67 to rotate. Under the meshing action, the driving gear 67 drives the driven gear 64 to rotate, and then drives the rotating shaft 61 and the take-up roller 62 to rotate, and the cable 63 is released. Through the cooperation of the hinge 11, the protective plate 51 is laid flat to achieve the overlap of the protective plate 51 on the building. The construction personnel push the feeding dump truck through the protective plate 51 into the building. At this time, the two clamping plates 55 protect the construction personnel and there is no gap between the clamping plates 55 and the protective plates 51. When the material in the feeding dump truck splashes, the splashed material will not fall from a high place to the ground, avoiding harm to the construction personnel on the ground, and effectively avoiding the problem that the splashed material is easy to hit the ground and cause casualties when the elevator is used to transport materials.
