[0002] In the construction process, construction elevators with high load-bearing capacity are required to facilitate the smooth vertical transportation of goods and tools. During operation, construction elevators typically carry large loads, and the inertia of the loads during each start and stop places a significant burden on the elevator. This can accelerate the deformation of the floor slab inside the car. Therefore, we propose a high-load-bearing construction elevator. Utility Model Content

A reinforcing beam is fixedly connected to the bottom of each pressure ear. A supporting beam is fixedly connected to the bottom of the groove. A first damper is fixedly installed between the supporting beam and the reinforcing beam. A reinforcing base plate is fixedly connected to the bottom of the U-shaped load-bearing frame.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0020] A high-load-bearing construction elevator includes an elevator car 1. A U-shaped load-bearing frame 3 is movably connected inside the elevator car 1. Both ends of the U-shaped load-bearing frame 3 are symmetrically bent outwards and have pressure ears. The pressure ears slide along a sliding groove 12 opened on the inner side wall of the elevator car 1. A reinforcing beam 31 is fixedly connected to the bottom of the pressure ears. A support beam 6 is fixedly connected to the bottom of the sliding groove 12. A first damper 5 is fixedly installed between the support beam 6 and the reinforcing beam 31. Several first dampers 5 are fixedly installed at equal intervals along the front-back direction on the top of the support beam 6. A reinforcing base plate 7 is fixedly connected to the bottom of the U-shaped load-bearing frame 3. A load-bearing base 8 is embedded and fixed in the elevator car 1 below 7. A second damper 9 is fixedly installed between the reinforcing base plate 7 and the load-bearing base 8. Several second dampers 9 are fixedly installed in a rectangular array on the top of the load-bearing base 8. Insert rods 71 ​​are symmetrically fixed at the bottom of the reinforcing base plate 7 on both sides of the second damper 9. A slot 81 is opened on the top of the load-bearing base 8. The lower end of the insert rod 71 is movably inserted into the insert rod 71. A damping sleeve 10 is movably sleeved on the insert rod 71. Through the arrangement of the first damper 5, the second damper 9 and the damping sleeve 10, the elevator car 1 can be damped during upward movement. The U-shaped load-bearing frame 3 is cushioned by the inertia of the object, effectively preventing excessive stress and deformation. Simultaneously, the supporting beam 6 and load-bearing base 8 enhance the load-bearing capacity of the elevator car 1. Side ventilation windows 11 are symmetrically arranged on both sides of the elevator car 1. A door 2 is movably installed through the top of the elevator car 1. The door 2 is driven by a motor; this driving method is existing technology and will not be described in detail here. A front ventilation window 21 is located at the top of the door 2. During use, as the elevator car 1 moves upwards carrying a load, the U-shaped load-bearing frame 3 is cushioned by the load. Due to the inertia of the body, it will move downwards. At this time, the U-shaped load-bearing frame 3 moves downwards, which can drive the reinforcing beam 31 to squeeze the first damper 5. At the same time, it can drive the reinforcing base plate 7 to move downwards, squeezing the second damper 9 and the damping sleeve 10. Through the combined action of the first damper 5, the second damper 9 and the damping sleeve 10, the vibration reduction and buffering of the U-shaped load-bearing frame 3 can be achieved, preventing the U-shaped load-bearing frame 3 from deforming due to excessive force. During this process, the support beam 6 and the load-bearing base 8 can strengthen the structural strength of the elevator car 1, making the load-bearing capacity of the elevator car 1 stronger.

[0021] A rubber pad 4 is laid on the top of the U-shaped load-bearing frame 3. A limiting protrusion 32 is fixedly installed on the top of the U-shaped load-bearing frame 3. A connecting groove 41 is opened at the bottom of the rubber pad 4, and the connecting groove 41 is connected with the limiting protrusion 32. A pick-up column 42 is fixedly installed at the two corners on the rear side of the rubber pad 4. The rubber pad 4 can prevent the load from directly contacting the U-shaped load-bearing frame 3 and causing wear to the U-shaped load-bearing frame 3, thus better protecting the U-shaped load-bearing frame 3. The rubber pad 4 can be removed and replaced by manually pinching the pick-up column 42. During use, the rubber pad 4 can prevent the load from causing wear to the U-shaped load-bearing frame 3. When the rubber pad 4 needs to be replaced, it can be removed and replaced by pinching the pick-up column 42 and pulling upward.

[0022] Working principle: During use, as the elevator car 1 moves upward with the load on it, the U-shaped load-bearing frame 3 moves downward due to the inertia of the load. This downward movement of the U-shaped load-bearing frame 3 causes the reinforcing beam 31 to compress the first damper 5, and simultaneously causes the reinforcing base plate 7 to move downward, compressing the second damper 9 and the damping sleeve 10. Through the combined action of the first damper 5, the second damper 9, and the damping sleeve 10, vibration damping and buffering of the U-shaped load-bearing frame 3 are achieved, preventing excessive force and deformation. During this process, the support beam 6 and the load-bearing base 8 strengthen the structural strength of the elevator car 1, increasing its load-bearing capacity. During use, the rubber pad 4 prevents wear on the U-shaped load-bearing frame 3 caused by the load. When the rubber pad 4 needs to be replaced, it can be removed and replaced by pinching and pulling the column head 42 upwards.
