Description

Technical Field

[0001] This utility model relates to the field of elevator car frame technology, and in particular to an elevator car frame that is easy to assemble. 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] Existing elevator car frames designed for machine-room-less systems have several shortcomings. First, the car frame base, vertical beams, and horizontal beams cannot be quickly assembled, making the assembly process cumbersome. Second, the upper guide shoes are inconvenient to install and remove; when installation or removal is required, one must climb to the elevator car frame horizontal beams. Therefore, existing elevator car frames designed for machine-room-less systems need to be optimized and improved. Summary of the Invention

[0004] The purpose of this utility model is to overcome the above-mentioned problems existing in the traditional technology and provide an elevator car frame that is easy to assemble.

[0025] Upper guide shoe installation, disassembly, and working principle Installation: The rectangular sliding sleeve 401 of the upper guide shoe 4 is fitted onto the outer side of the vertical beam 1, allowing for vertical sliding. A first vertical plate 402 is fixed to the lower side of the rectangular sliding sleeve 401 near its outer end. The first vertical plate 402 has a third stepped hole 403 that mates with the second fastener 6. Several second fastening screw holes 105, equidistant from each other, are provided on the upper outer side of the vertical beam body 101 to mate with the second fastener 6. After sliding the upper guide shoe 4 to a suitable position, the second fastener 6 is passed through the third stepped hole 403 and screwed into the second fastening screw hole 105, thus locking the upper guide shoe 4 in its position on the vertical beam 1. A second vertical plate 404 is fixed to the lower side of the rectangular sliding sleeve 401 near the inner end. A fixing plate 406 is installed at the top of the second vertical plate 404. A guide shoe 409 is movably connected to the bottom end of the fixing plate 406. A guide shoe base 407 is movably connected to the bottom end of the guide shoe 409. A guide shoe fixing block 405 is movably connected to one end of the guide shoe 409. A guide shoe mounting plate 408 is fixedly connected to the inner side of the fixing plate 406. The guide shoe fixing block 405 is embedded inside the second vertical plate 404, thus completing the installation of the upper guide shoe.

[0026] Disassembly: When it is necessary to disassemble the upper guide shoe, simply unscrew the second fastener 6 to release the position lock of the upper guide shoe 4, and then slide the upper guide shoe 4 vertically along the vertical beam 1 to remove it from the vertical beam 1. This eliminates the need to climb to the elevator car frame beam for operation, making it convenient and quick. During elevator operation, the guide shoe 409 contacts the hoistway guide rails, guiding and stabilizing the car to ensure smooth car operation.
