Abstract
The utility model belongs to the technical field of the anti-falling product for the aloft work, in particular to an anti-falling apparatus. The utility model is mainly and technically characterized in that a shell is included; a sliding chute which can clip an anti-falling slideway and which is formed by enclosing an inwardly-folding edge is arranged on the side of the shell; on another side of the shell, a shift lever which can be rotated through a shift level pivot and which is fixed on the shell is arranged; one end of the shift lever is contacted with the anti-falling slideway and the other end is fixed with a safety rope. The utility model solves the technical problem of the operation inconvenience of the current anti-falling apparatus and can be widely used in such fields as the communication tower, power tower, etc.
Description
Technical field
The utility model belongs to work high above the ground fall arrest product technical field, relates in particular to a kind of falling proof device.
Background technology
At present, the personnel for cat ladder carries out work high above the ground to be on the safe side, in traveling process, adopt two safety ropes, the segment distance of advancing, and just wherein a safety rope is fixed; Continue up then, the segment distance of advancing, again another root safety rope is fixed, following safety rope is untied, continue up, and so forth, not only gait of march is slow, and, in case top safety rope comes off, the people knows from experience the segment distance that falls, and in the high speed dropping process human body is caused certain injury.
The utility model content
The technical problem of solution of the present utility model just provides a kind of falling proof device of easy to use, vi have high safety.
The technical solution adopted in the utility model is: comprise housing, be provided with the chute of the snapped in fall arrest slideway that surrounds by interior flanges in the side of described housing, be provided with by the rotatable driving lever that is fixed on the described housing of driving lever fulcrum in the another side of described housing, driving lever one end contacts with the fall arrest slideway, and the other end and safety rope are fixed.
Its additional technical feature is: described driving lever is connected with described housing by elastic mechanism; Described elastic mechanism is a spring; Described housing is divided into left side and right-hand part, and described left side is connected by slide bar with right-hand part, and controls by controlling organization; Disalignment one side is provided with the bar shaped projection on described fall arrest slideway, is provided with strip groove with fall arrest slideway correspondence position in described chute.
Compared with prior art provided by the utility model, have the following advantages: one, owing to be provided with the chute of the snapped in fall arrest slideway that surrounds by interior flanges in the side of described housing, be provided with by the rotatable driving lever that is fixed on the described housing of driving lever fulcrum in the another side of described housing, driving lever one end contacts with the fall arrest slideway, the other end and safety rope are fixed, in the up process of human body, driving lever and fall arrest slideway almost are in released state, falling proof device upwards slides along the fall arrest slideway, when unexpected downslide, under the effect of safety rope, driving lever rotates along the driving lever fulcrum, driving lever end extruding fall arrest slideway, and the pressure of the interior flanges of housing side and fall arrest slideway increases feasible frictional force increase therebetween, human body is not easy to glide, and plays the purpose of fall arrest; Its two because driving lever is connected with described housing by elastic mechanism, make the driving lever end contact with the fall arrest slideway all the time, human body is in case downslide, the rapid and fall arrest slideway effect of driving lever energy, the segment distance that is unlikely to glide damages human body; Its three because housing is divided into left side and right-hand part, described left side is connected by slide bar with right-hand part, and by controlling organization control, is convenient to this falling proof device is installed on the fall arrest slideway; Its four because disalignment one side is provided with the bar shaped projection on described fall arrest slideway, in described chute, be provided with strip groove with fall arrest slideway correspondence position, when preventing to install that this falling proof device dress is anti-, do not have skidproof effect.
Description of drawings
Fig. 1 is the structural representation of the utility model falling proof device;
Fig. 2 is the utility model falling proof device vertical view;
Schematic diagram when Fig. 3 is installed separately for housing left and right sides two parts.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the utility model falling proof device.
Shown in Figure 2 as Fig. 1, the utility model falling proof device, comprise housing 1, lateral edge 2 invaginations of housing 1 form chute 3, and chute 3 can snap on the fall arrest slideway 4, be provided with driving lever 5 in the another side of housing, driving lever 5 is by driving lever fulcrum 6 rotatable being fixed on the housing 1, and an end of driving lever 5 contacts with fall arrest slideway 4, and the other end and safety rope 7 are fixing.
In order to make driving lever 5 ends contact with fall arrest slideway 4 all the time, in a single day human body glides, rapid and fall arrest slideway 4 effects of driving lever 5 energy, and the segment distance that is unlikely to glide damages human body, and driving lever 5 passes through to be connected with housing 1 by elastic mechanisms such as spring 8.
For the ease of housing 1 is installed on the fall arrest slideway 4, housing is divided into left side 11 and right-hand part 12 as Fig. 3, and left side 11 is connected by slide bar 13 with right-hand part 12, and by controlling organization 14 control, and controlling organization 14 is as jump ring lock in the prior art etc.
This falling proof device dress is anti-in order to prevent to install, disalignment one side is provided with bar shaped projection 41 on fall arrest slideway 4, chute 3 in and fall arrest slideway 4 correspondence positions be provided with strip groove 31.
During use, earlier controlling organization 14 is opened, chute 3 is fixing with fall arrest slideway 4, locking controlling organization 14, safety rope 7 is fixed on the human body, upwards in the traveling process, driving lever 5 almost is in released state with fall arrest slideway 4, and falling proof device upwards slides along fall arrest slideway 4, when unexpected downslide, under the effect of safety rope 7, driving lever 5 rotates along driving lever fulcrum 6, driving lever 5 ends extruding fall arrest slideway 4, and the interior flanges 2 of housing 1 side also increases with the pressure of fall arrest slideway 4, make between interior flanges 2 and the fall arrest slideway 4 and the increase of the frictional force between driving lever 5 and the fall arrest slideway 4, human body is not easy to glide, and plays the purpose of fall arrest.
