摘要： An elevator anti-fall buffer based on flexible guidance. The anti-fall buffer is used for connecting and fixing an end part of a braking steel rope of an elevator. The anti-fall buffer has an upper support plate and a lower support plate, wherein a pulley set is provided on the upper support plate and the lower support plate, and a hydraulic damping buffer is provided at two sides of the pulley set. The anti-fall buffer uses the energy consumption principle of a hydraulic damping hole, and while protecting the braking steel rope from the force of impact created thereon by the elevator, prevents the force of impact from a spring on the elevator post-braking, improving the safety and reliability of elevator braking, thereby improving safety of an elevator, while also using a pulley set can increase the braking distance of the braking steel rope, thereby lengthening life of the steel rope.

摘要： A hydraulic elevating platform having no guide rails and an elevating method. A hydraulic power pack drives three parallel hydraulic cylinders to work synchronously, thereby implementing the rising and falling of an elevating platform; when the elevating platform reaches a predetermined floor, an upper electric pushrod pushes a pedal assembly out, and then the pedal assembly drives a pedal to rise by means of a pedal elevating system until the pedal is flush with the surface of a loading table of the elevating platform; outward-swinging doors between the elevating platform and a floor open to form pedal guardrails; then sliding doors open and a man can step onto a stair via the pedal assembly. An eccentric loading adjusting means eliminates eccentric loading to achieve balance about the center of gravity, thereby eliminating the eccentric loading of the platform. The elevating platform is simple in structure, safe, reliable, and easy to maintain. The elevating platform, placed within a spiral stair, is convenient for movement of crowds and cargo delivery at certain scenarios and is widely applicable. The elevating method is simple to implement and effectively solves the eccentric loading problem caused by reasons such as outstretching of a pedal of a hydraulic elevating platform and uneven distribution of people on the elevating platform, so that the hydraulic elevating platform is more stable and reliable during operation.

The sliding rod (1-10) moves in a strip-opening sliding slot in the rotating rod (3) by the sliding plate (1-9) moving up and down, then the rotating rod (3) and a carrying plate (5-1) are driven to move circumferentially. A rocker (5-3) is rotated around a supporting bracket (5-4) driven by a connecting rod (5-2), thus a credible carrying platform in multi-plane is realized. The platform is simple in structure, controlled accurately, convenient to be fixed and maintained, operated stably and reliably, and has the self-locking function.
