Description

Technical Field

[0001] This utility model relates to the field of elevator car frame technology, and in particular to a connection structure for a combined elevator car frame. Background Technology

[0002] The elevator car frame is the core support structure of the elevator system, bearing the car. Its core functions can be summarized in three points: First, as the "skeleton" of the car, the car frame forms a rigid frame through components such as vertical beams and horizontal beams, ensuring the car maintains a stable shape during operation and effectively suppressing deformation even under dynamic loads (such as passenger movement or cargo off-center loading). Second, the car frame serves as the force transmission hub, evenly transmitting the car's own weight, load, and operating impact force to the hoistway guide rails through guide shoes. Simultaneously, it transmits emergency braking force through the safety clamp mechanism, making it a key carrier of the elevator's mechanical safety system. Third, the car frame is flexibly connected to the car body through elastic elements, isolating guide rail vibration noise and avoiding resonance caused by rigid contact, significantly improving passenger comfort. Furthermore, the car frame integrates key interfaces such as traction rope pulleys and compensating chain suspension points; its structural strength directly determines the elevator's load capacity and service life. Modern car frames further balance strength and energy consumption through lightweight design, becoming an important element in optimizing elevator energy efficiency.

[0003] The existing connection structure of modular elevator car frames has shortcomings in use. It cannot achieve rapid assembly and connection of modular elevator car frames, nor can it meet the assembly requirements of elevator car frames of different widths. Therefore, it is necessary to optimize and improve the existing connection structure of modular elevator car frames. Summary of the Invention

[0018] In this embodiment, the first car frame component 1 includes a first vertical beam 101, a first upper crossbeam 102, a first connecting plate 103, and a first lower crossbeam 104. The upper end of the first vertical beam 101 is vertically connected to the first upper crossbeam 102, and the lower end of the first vertical beam 101 is vertically connected to a plurality of first lower crossbeams 104 via the first connecting plate 103. The outer ends of the first upper crossbeam 102 and the first lower crossbeam 104 are provided with a plurality of first clamping plates 105.

[0019] In this embodiment, the second car frame component 2 includes a second vertical beam 201, a second upper crossbeam 202, a second connecting plate 203, and a second lower crossbeam 204. The upper end of the second vertical beam 201 is vertically connected to the second upper crossbeam 202, and the lower end of the second vertical beam 201 is vertically connected to a plurality of second lower crossbeams 204 via the second connecting plate 203. The outer ends of the second upper crossbeam 202 and the second lower crossbeam 204 are provided with a plurality of second clamping plates 205 that interlock with the first clamping plate 105.

[0020] In this embodiment, the connecting sleeve 3 is sleeved on the outside of the first clamping plate 105, the second clamping plate 205 and the crossbeams thereon, and is connected to the corresponding crossbeams by fastening screws 4 respectively.

[0021] In this embodiment, the first car frame component 1 is symmetrically provided with a first reinforcing rib plate 107 between the side end of the first vertical beam 101 and the upper end of the first connecting plate 103, and the second car frame component 2 is symmetrically provided with a second reinforcing rib plate 207 between the side end of the second vertical beam 201 and the upper end of the second connecting plate 203.

[0022] In this embodiment, the first car frame component 1 has a row of first fastening holes 106 that cooperate with fastening screws 4 on the upper side of the first upper crossbeam 102 and the lower side of the first lower crossbeam 104, and the second car frame component 2 has a row of second fastening holes 206 that cooperate with fastening screws 4 on the upper side of the second upper crossbeam 202 and the lower side of the second lower crossbeam 204.

[0023] In this embodiment, the interior of the connecting sleeve 3 is provided with a rectangular sliding cavity 301 that matches the cross-sectional shape of each beam, and the outer side plate of the connecting sleeve 3 is symmetrically provided with two protruding tubes 302 for easy installation of fastening screws 4.

Then, connect and fix them using the connecting sleeve 3 and fastening screws 4 to meet the assembly requirements of different widths. At the same time, the first reinforcing rib plate 107 and the second reinforcing rib plate 207 enhance the structural strength of the first car frame component 1 and the second car frame component 2, ensuring that the elevator car frame can withstand various loads during operation and guaranteeing the safe and stable operation of the elevator.
