Abstract
The utility model provides a guide rail of a fall protection device; the guide rail is a trough-shaped thin shell piece and comprises a bottom part 1, two side walls respectively connected with both ends of the bottom part 1, and two side wings 3 respectively connected with the top ends of the two side walls 2; the bottom part 1, side walls 2 and the side wings 3 are all thin-wall straight plates, and the angle between the bottom part 1 and the side walls 2 is a right angle or an obtuse angle. As the angle between the bottom part and the side walls of the guide rail is a right angle or an obtuse angle, the section of the guide rail is extended and open type. Ice blocks condensed in the trough of the guide rail can be removed conveniently, the adaptive capacity of the fall prevention device is improved accordingly, the safety is also improved so that the fall protection device still has superior performance and reliable fall protection function in high altitude or highland cold regions and snow and freezing rain weather conditions.
Description
Technical field
The high-altitude fall arrest lifesaving safety device that uses when the present invention relates to the ascend operation of industries such as electric power, chemical industry, building relates in particular to a kind of guide rail of falling proof device.
Background technology
In industries such as electric power, chemical industry, building, all be unable to do without ascend operation, begin to install fall protection device for working at height more and more to ensure operating personnel's safety.Falling proof device product in the market mainly comprises buckle-type falling proof device and friction-type falling proof device.Wherein the buckle-type falling proof device obtains using more widely because fault rate is low, safety coefficient is high.
In falling proof device, guide rail is indispensable some.Buckle-type falling proof device in the market mainly uses C type guide rail.This guide rail can play anti-fall effect under the normal temperature.But under cold districts such as high latitude or plateau and ice and snow sleet weather condition, the ice that guide rail can be condensed wraps.At this moment, the C type guide rail of buckle-type falling proof device, because its cross section is semiclosed shape, the ice cube that condenses in inside is difficult for removing, and influences the use of falling proof device.
Summary of the invention
The technical problem that the utility model solves provides a kind of guide rail of falling proof device, makes it under cold and sleety weather, removes the inner ice cube that condenses easily.
For solving the problems of the technologies described above, the utility model adopts following technical scheme,
A kind of guide rail of falling proof device, it is a groove shape thin shell piece, comprise the bottom, be connected to the two ends, bottom two sidewalls, be connected to two flanks on two sidewall tops; Bottom, sidewall, flank are the straight plate of thin-walled, and the angle between bottom and the sidewall is right angle or obtuse angle.
Further, the bottom of guide rail offers along its length and is used for anti-fall braking and bolt and is connected and fixed and uses through hole.
Particularly, described through hole is evenly arranged by the identical distance distance along the bottom lengths direction.
Compared with prior art, the utlity model has following beneficial effect:
Because the bottom and the angle between the sidewall of guide rail are right angle or obtuse angle, its cross section is that abduction is open.This kind structure is convenient to remove the ice cube that its groove inner accumulated is condensed, thereby increase the adaptive capacity of its falling proof device that cooperates, improve its security, make it under cold districts such as high latitude or plateau and ice and snow sleet weather condition, do not change service behaviour, still possess and prevent the function of falling reliably.
Description of drawings
Fig. 1 is the upward view of the guide rail specific embodiment of the utility model falling proof device;
Fig. 2 is the cross section structure schematic diagram of the guide rail specific embodiment of the utility model falling proof device.
The specific embodiment
Elaborate the utility model below in conjunction with accompanying drawing.
With reference to shown in Figure 2, the guide rail specific embodiment of the utility model falling proof device is a groove shape thin shell piece, and it comprises bottom 1, be connected to two sidewalls 2 at two ends, bottom, be connected to two flanks 3 on two sidewall tops.Bottom 1, sidewall 2, flank 3 are the straight plate of thin-walled, and this guide rail specific embodiment integral body can be made by a straight plate punching press of thin-walled.Angle between bottom 1 and the sidewall 2 is right angle or obtuse angle, and for example arbitrarily angled between 90 degree-120 degree, the angle between described sidewall 2 and the described flank 3 is right angle or obtuse angle, and for example the cross section is
Shape.
With reference to shown in Figure 1, the bottom 1 of the guide rail specific embodiment of the utility model falling proof device evenly offers through hole 4 along its length, is used to snap in buckle with the realization braking, and then realizes preventing to fall; Or the bolt that is used for guide rail and body of the tower is connected and fixed the hole.
Because the bottom and the angle between the sidewall of guide rail are right angle or obtuse angle, its cross section is that abduction is open, this kind structure is convenient to remove the ice cube that its groove inner accumulated is condensed, thereby increase the adaptive capacity of its falling proof device that cooperates, improve its security, make it under cold districts such as high latitude or plateau and ice and snow sleet weather condition, not change service behaviour, still possess and prevent the function of falling reliably.
The above only is the specific embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
