Abstract
The utility model relates to a kind of rail catching device of aloft work anti-falling, and this rail catching device comprises: lead left piece, lead right piece, auxiliary guide rail, anti-fall block tongue, back-moving spring, block tongue steady pin, guide pad steady pin, guide pad screw and auxiliary guide rail screw.Its working method: this rail catching device needs to be connected on T-steel rail and uses, first the hook hole of rail catching device is connected on personal safety equipment before using, then the guide-track groove of rail catching device is passed T-steel rail, this rail catching device finally can be made to slide on T-steel rail and not come off.The feature of the utility model patent is: the anti-fall block tongue of this rail catching device is cam structure, can strengthen coupling mechanism force along with the increase of bearing down; Anti-fall block tongue is strained by back-moving spring, can ensure that anti-fall block tongue is in elastic compression state to T-steel rail; Auxiliary guide rail is connected on rail catching device by auxiliary guide rail screw, reduces friction when being free to slide and adds the frictional force of falling and locking.
Description
Technical field
The utility model relates to the falling-proof safety device in a kind of work high above the ground environment, particularly relates to a kind of rail catching device.
Background technology
In industries such as wind-powered electricity generation, building, bridges, in order to ensure the construction safety of aloft work personnel, the fall arrest facility that necessary installation reliability energy is high, rail catching device is exactly the important falling prevention device connecting dangerous vertical plane and workmen in the sector, by this equipment, workmen freely can walk about safely within the specific limits along the direction of T-steel rail.
Summary of the invention
The purpose of this utility model is to provide the falling proof device on a kind of vertical life line system, can eliminate the potential safety hazard of operating personnel in work high above the ground.
For achieving the above object, the utility model for the technical scheme realizing above-mentioned functions and take is: this rail catching device comprises: lead left piece, lead right piece, auxiliary guide rail, anti-fall block tongue, back-moving spring, block tongue steady pin, guide pad steady pin, guide pad screw and auxiliary guide rail screw.
Lead left piece, lead right piece together with anti-fall block tongue to be concatenated into guide pad steady pin by block tongue steady pin, form a T-shaped railtrack grooves, can slide on T-steel rail.
Anti-fall block tongue is serially connected on block tongue steady pin, block tongue steady pin and guide pad steady pin two ends are by guide pad screw in compression, anti-fall block tongue can rotate around rail catching device, and keep position of rotation by back-moving spring when free state, increase friction thus anti-fall by compressing T-steel rail when falling.
Auxiliary guide rail is tightened in the guide-track groove of left piece of guiding and right piece of guiding by multiple guide rail holding screw; Back-moving spring one end is fixed to right piece of guiding, and the other end connects anti-fall block tongue, is all placed in rail catching device.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, detailed description of the invention of the present utility model is described in further detail.Following embodiment for illustration of the utility model, but can not limit protection domain of the present utility model with this.
As shown in Figure 1, with pin hole in lead right piece 1 and guiding left piece 7, block tongue steady pin 4 and guide pad steady pin 5 connect together through this pin hole of serial connection, and through anti-fall block tongue 2 in the middle of lead right piece 1 and guiding left piece 7.
As shown in Figure 1, auxiliary guide rail 6 is tightened to guiding right piece 1 by multiple auxiliary guide rail screw 9 and leads in the guide-track groove of left piece 7, auxiliary guide rail 6 is free to slide in process at rail catching device 10 the direct rigidity friction avoiding rail catching device 10 and T-steel rail 11, and the friction effect can strengthened in drop event, enhance safety in utilization.
As shown in Figure 1, back-moving spring 3 two ends are half coil structures, one end hooks leads on the connecting hole of right piece 1, one end is connected on the connecting hole of anti-fall block tongue 2, anti-fall block tongue 2 is tightened to T-steel rail 11 in advance on the surface by anti-fall block tongue 2 under the tensioning function of back-moving spring 3, ensure the impaction state of anti-fall block tongue 2 to T-steel track surface under non-external force state, shorten impact distance, the anti-fall effect caused because impact distance is long avoided when falling suddenly lost efficacy.
As shown in Figure 2, rail catching device 10 free slide on T-steel rail 11 under normal operating conditions.
As shown in Figure 3, anti-fall block tongue 2 cross section curve of this rail catching device 10 adopts the cam structure of evolvent type, anti-fall block tongue 2 can be made to rotate around block tongue steady pin 4 when wearer falls accidentally, thus make the cam structure of anti-fall block tongue 2 with to rotatably compress on T-steel rail 11 and more to turn tighter, formed and a kind ofly carry out anti-fall system by increasing friction.
As can be seen from above example, feature of the present utility model is: this rail catching device mechanism structure is simply novel, is easy to installation operation, safe and reliable; The auxiliary guide rail of this catching device reduces the wearing and tearing of contact site, enhances the safety coefficient of equipment, and the cam structure of this catching device evolvent type, effectively increase drag friction effect, ensure that the safety of wearer.
