Implementation

[0024] The utility model is further described in conjunction with the following embodiments.

[0025] A specific implementation of the passenger elevator load-bearing device installation structure of the utility model is as follows Figure 2 As shown, it includes a load-bearing main beam 2, a main frame 3, a shock-absorbing rubber component 4, a car rope head plate 5 and a counterweight rope head plate 6.

[0026] In this embodiment, the number of the load-bearing main beams 2 is two, and the two load-bearing main beams 2 are arranged in the transverse direction ( Figure 2 From left to right is horizontal) and in vertical ( Figure 2 They are arranged in parallel with each other in the vertical direction (from top to bottom).

[0027] As an improvement, combined with Figure 3 The main frame 3 is fixedly mounted between the two load-bearing main beams 2. Specifically, the main frame 3 includes two channel steels 31 arranged at intervals in the transverse direction. The two channel steels 31 are parallel and arranged longitudinally and fixed above the load-bearing main beam 2. The top surface of each channel steel 31 is fixedly installed with a bottom plate 32 for fixing the external mainframe. As a preferred solution, the channel steel 31 adopts a U-shaped channel steel 31, which has high structural strength and anti-twisting performance, and can ensure the bearing capacity of the load-bearing beam structure.

[0028] As a preferred solution, the main frame 3 also includes a reinforcing plate 33, the side of the reinforcing plate 33 is welded and fixed to the side of the channel steel 31, and the top surface of the reinforcing plate 33 is welded and fixed to the bottom surface of the bottom plate 32. The reinforcing plate 33 plays the role of a reinforcing rib, which can reinforce the connection strength between the bottom plate 32 and the channel steel 31. In addition, the main frame 3 also includes a connecting piece 34, one end of the connecting piece 34 is fixed to the inner side of one of the channel steels 31, and the other end of the connecting piece 34 is fixed to the inner side of another channel steel 31, so that the connecting piece 34 is welded and fixed between the two channel steels 31, which can further improve the structural strength of the main frame 3.

[0029] In order to reduce the impact of vibration generated by the mainframe on the load-bearing beam structure during operation, a shock-absorbing rubber component 4 is provided between the mainframe 3 and the load-bearing main beam 2. Figure 4The shock-absorbing rubber assembly 4 includes a base plate 41, a colloid 42 and a pad 43. The base plate 41 is fixedly mounted on the top surface of the load-bearing main beam 2, the colloid 42 is fixedly mounted on the top surface of the base plate 41, and the pad 43 is fixedly mounted on the top surface of the colloid 42. The pad 43 extends studs 44 upward. Through holes are provided on both sides of the base plate 41. During installation, corresponding through holes are provided on the load-bearing main beam 2. The shock-absorbing rubber assembly 4 can be fixedly mounted on the top surface of the load-bearing main beam 2 by external bolts and nuts, and the studs 44 of the pad 43 can cooperate with the through holes and nuts provided on the channel steel 31, so as to fix the channel steel 31 on the top of the load-bearing main beam 2. The elasticity of the colloid 42 plays a buffering role, which can reduce noise and provide a certain protection for the load-bearing main beam 2.

[0030] As another improvement, the shock-absorbing rubber assembly 4 also includes a gasket 45, which is fixedly mounted on the bottom surface of the base plate 41. When the shock-absorbing rubber assembly 4 is fixedly mounted on the load-bearing main beam 2, the gasket 45 is located between the base plate 41 and the load-bearing main beam 2. The gasket 45 is an elastic gasket 45, which can fill the gap between the base plate 41 and the load-bearing main beam 2 that may exist due to unevenness, and ensure the contact area between the shock-absorbing rubber assembly 4 and the load-bearing main beam 2, thereby improving the shock-absorbing effect, and the gasket 45 can further play a role in shock absorption and buffering.

[0031] In this embodiment, the load-bearing device installation structure also includes a car rope head plate 5, which is arranged longitudinally and fixedly installed between two load-bearing main beams 2. As a preferred solution, the car rope head plate 5 is welded and fixed to the load-bearing main beam 2. In addition, the load-bearing device installation structure also includes a counterweight rope head plate 6, which is welded and fixed to the side of one of the load-bearing main beams 2. The counterweight rope head plate 6 can also be fixed together with the connecting bolts between the shock-absorbing rubber assembly 4 and the load-bearing main beam 2.
