Description
Technical field
The utility model relates to a kind of skid being applied to pipeline, particularly discloses a kind of life-saving skid based on balustrade.
Background technology
At fire-fighting domain, the fire fighting equipment or the equipment that are applied to corridor escape are less.In most corridor survival equipment, the devices such as slide are usually adopted to escape apparatus as corridor.Its shortcoming is that volume is too huge, installs inconvenience, cannot realize withdrawing fast.
In order to address this problem, application number be 201320731041.9 utility model patent disclose a kind of stair rail slideway for fire prevention escape, it well solves above shortcoming, but the structure of its skid and processing technology more complicated, and processing request is higher.
In order to reduce difficulty of processing, application number be 201520297202.7 utility model patent disclose a kind of loading skid being applied to pipe pipe fitting, simplify the structure of down slide device, realize glide smoothly.But the downslide parts of this loading skid are made up of linear bearing, in actual applications, the processing of linear bearing needs certain precision, the fluting of cannelure is cumbersome, easily occur error, causes between ball with cannelure and coordinates compensation, increases scrappage, simultaneously, because parts are more, when combinationally using, can fatigue strength be increased, cause shorten service life.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, provides a kind of structure to simplify further, and result of use is good, the life-saving skid based on balustrade conveniently processing, reduce costs.
The utility model is achieved in that a kind of life-saving skid based on balustrade, comprise downslide parts, connecting rod, brake part, bearing bar, described brake part is fixed on the upper end of described bearing bar, lower end and the described bearing bar of described connecting rod are rotatedly connected, the upper end of described connecting rod is connected with described downslide parts, described downslide parts and brake part form pipe fitting hold assembly jointly, it is characterized in that: described downslide parts comprise pedestal, slide block, described slide block is fixed in described pedestal, the bottom surface of described slide block is pipe fitting contact surface, described pipe fitting contact surface is the arc surface of fovea superior, the coefficient of friction of described pipe fitting contact surface is 0.12 ~ 0.17, the top of described pedestal and/or the side of pedestal are fixed on the upper end of described connecting rod.
The hardness of described slide block is shore 55--65.
Described slide block is polytetrafluoroethylene (PTFE) slide block.
The end face of described pedestal is rounded, and the front projection of described pedestal is: the bottom of rectangle cuts out the semicircle that a radius is less than described rectangular elevation.
Be provided with bayonet socket in described pedestal, described slide block is fixed in described pedestal by described bayonet socket.
The gliding speed of described pipe fitting hold assembly on pipe fitting is 0.8m/s ~ 1.2m/s.
The beneficial effects of the utility model are: mainly on the basis of existing technology improve downslide parts, while structure is simplified further, improve service life and reduce difficulty of processing.The utility model service free, durable for a long time, slide steady noiselessness, and the more simple weight of processing is lighter, has all advantages that application number is the utility model patent of 201320731041.9 simultaneously.
