Background technology
Along with the nationwide integrated power grid construction in develop rapidly, the operation of being engaged in the transmission and transformation engineering eminence is very frequent, in the construction and operating maintenance climbing of power transmission sequence shaft tower, because iron tower and bar itself do not have the auxiliary equipment of fall arrest.Particularly under adverse weather condition (as rainy season, winter); the staff does not have reliable fall arrest safeguard measure in climbing and descending process; the high-rise working danger close; because of the high-altitude falling accident idol of slipping up or other reasons causes has generation; in case generation and fall in the high-altitude; generally directly cause the personnel death that falls; therefore guarantee that staff's job safety just seems very urgent and necessary; in today of paying attention to " people-oriented ", can develop a cover effectively protection electric operating personnel up and down the equipment of tower safety be extremely important.Potential safety hazard at present domestic power transmission sequence work high above the ground existence, some producers have developed work high above the ground and have climbed self-locking device, but owing to himself product structure function singleness, security reliability is low, anti-corrosion ability and anti-theft capability are weak, actual operability is not strong, carry heaviness, well meeting the market requirement is extensively promoted the use of limited on a large scale.
The utility model content
The purpose of this utility model provides a kind of rail mounted fall protection equipment that is applied to high pressure/extra high voltage network shaft tower work high above the ground.Its guide rail is fixedly mounted on the shaft tower, its self-locking device can slide along track during shaft tower up and down synchronously with personnel, to prevent the human body fall, in case self-locking device loses the traction of human body, self-locking device is locked on the guide rail immediately, and distance of fall is little, and impulsive force is little, do not cause the secondary injury, effectively prevented the injury that accidental fall causes human body.
The technical scheme that the utility model provides is as follows: a kind of steel strand wire rail mounted fall protection equipment, it comprises steel strand wire guide rail and self-locking device, guide rail is fixedly mounted on the shaft tower, self-locking device slidably is set on the guide rail, and self-locking device comprises base, pressing plate, turnover panel, last connecting lever, following connecting lever, connecting rod and connecting axle; The last hole that connecting axle passes connecting lever and following connecting lever is connected connecting rod, by the fixing assembling of snap ring; Dowel fixes connects turnover panel and base; Pin, pin and compression spring housing are connected on the two ends of turnover panel and base.
The inside groove concave surface of described base is provided with the parallel line bar of coarse rigidity, and the circumferential surface of inside groove concave surface contacts with the steel strand wire guide rail.
Described connecting lever and the following connecting lever gone up, profile is class " L " font, and the bottom is the sealed head of rigidity projection, and convex surface is provided with the parallel line bar of coarse rigidity.
Described self-locking device is provided with return element dish-type spring, and two dish-type spring housings are connected between crutches arm and the base.
Each member of described self-locking device all adopts high-strength aluminum alloy material, and the surface is done anticorrosion technology and handled, and rust resistance is strong, below the weight 0.6kg, is applicable to the work high above the ground demand.
Described self-locking device can be set the designing technique parameter of self-locking device with reference to the standard of safety belt and other security products.
The utility model has solved transmission line construction personnel this problem of unshielded facility when climbing high tower, the transmission line construction personnel have not only been eliminated, the potential safety hazard of circuit operation and maintainer's work high above the ground, also the personnel for other ascend operation provide safety device, the fixed installation steel strand wire guide rail that adopts, install non-dismountable, effectively reduce the possibility of pilferage, track adopts the rare earth galvanized strand wires, the antirust processing of surface anode, the anti-wear performance height, rust resistance is strong, the material anti-corrosion reaches more than 30 years useful life, satisfy the instructions for use of shaft tower life-span, self-locking device is simple in structure general, and the high height of hanging is used, whole light-weight design adapts to its security reliability requirement, its portable design more meets workman's work high above the ground user demand simultaneously, and the product price ratio is very remarkable, has very big promotional value and wide application prospect.
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
