This patent relates to a multi-mode communication method for detecting states of power transmission line, which belongs to electric power communication technology field. In this method, there are sensing devices installed on power transmission line. These sensing devices are used to detect status signals of power transmission line. Status signals are sent to remote monitoring center through communication terminals. Both sensing devices and communication terminals are powered by battery. The main communication network between sensing devices and communication terminals is formed by ZigBee network. Meanwhile, Bluetooth network is a backup communication network between sensing devices and communication terminals. Communication terminals and remote monitoring center are linked through WinMAX. This method can take full advantage of these two short-range wireless communication technologies and break limitations of a single technology, ensure reasonable energy consumption, improve efficiency and quality of data transmission.

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.

A traction rope adjustment apparatus includes a traction rope pressing device, and a traction rope pulley apparatus. The traction rope lifting apparatus prevents the traction rope sagging, the traction rope pressing apparatus prevents the traction rope drifting, and the traction rope pulley apparatus enables a car and the counterweight to smoothly pass through the traction rope pressing apparatus, thereby implementing forced guidance of the traction rope and the reliable and smooth running of the car and counterweight. The apparatus can meet the demands of variable gradients and can implement reliable running of an inclined running container in variable gradients, such that the traction rope adapts to the different gradients, solving the challenge of the development of an inclined running container that self-adapts to gradients.
