Abstract
The utility model relates to a high altitude anti-dropping device, in particular to a high altitude anti-dropping C-shaped guide rail. The device adopts the technical proposal that the high altitude anti-dropping C-shaped guide rail comprises a rail body, wherein the rail body is provided with a bolt fixing hole and a protruded clamping base; only one side of the clamping base and the rail body are provided with an opening respectively; the front part of the claming base is substantially rectangular, and is longitudinally extended along the rail body; the rear part of the clamping base is substantially tapered; and one end of the rear part of the clamping base is connected with the front part of the clamping base, and the rest part of the clamping base is connected with the rail body. With the technical proposal, a high altitude anti-dropping C-shaped guide rail which can bear the load impact force and is safe and reliable is provided.
Description
Technical field
The utility model relates to the anti-fall equipment in a kind of high-altitude, particularly a kind of high-altitude fall arrest C shape guide rail.
Background technology
In fields such as electric power power transmission and transformation line shaft tower, power transformation framework, communication shaft tower and building, all be unable to do without ascend operation, in recent years, electric power development speed is very fast, requirement to the safety management level is more and more higher, the task of power grid construction and transformation is also more and more heavier, a large amount of constructions, service work task all relate to ascend operation, if there is not reliable fall arrest equipment, will cause huge potential safety hazard to the staff.
The base of used C shape guide rail is provided with deck and bolting hole in this type of fall arrest equipment, therefore this deck needs to bear very big impulsive force in the use of C shape guide rail, for the design strictness than the track of general friction-type fall arrest equipment of the safety requirements of C shape guide rail.
At present, the deck on the C shape guide rail mainly is that the base of punching press C shape guide rail forms, and is generally three limit open types, opening both sides, both sides are drawing; Excessive load shock is in use born in the design of this type of form might cause deck distortion or damage, and after the deck distortion, the staff's of work high above the ground safety then can not get ensureing.
Summary of the invention
At the deficiency that prior art exists, the utility model provides a kind of can bear load shock power, safe and reliable high-altitude fall arrest C shape guide rail.
For achieving the above object, the utility model provides following technical scheme: a kind of high-altitude fall arrest C shape guide rail, include the track body, described track body is provided with the deck of bolting hole and projection, and only it has opening with the track body on one side to described deck, and the forward part of deck is rectangular substantially, and along track body longitudinal stretching, its rear section is tapered substantially, and an end of rear section is connected with forward part, and remainder is connected with the track body.
Only it has opening with the track body on one side to deck in this, the forward part of deck is rectangular substantially, and along track body longitudinal stretching, its rear section is tapered substantially, one end of rear section is connected with forward part, and remainder is connected with the track body, is arranged so that like this deck forms stressed an of triangular form, make its stress surface become big, can bear than heavy load.
The utility model further is set to: described deck has four edges, and its front portion is divided into the working end, is provided with opening between the limit at place, this working end and the track body, and the deck rear section has three limits, is the cambered surface transition and is connected respectively with between the track body.
Deck has four edges in this, and its front portion is divided into the working end, is provided with opening between the limit at place, this working end and the track body, and the deck rear section has three limits, is the cambered surface transition and is connected respectively with between the track body.Be provided with simple in structurely like this, punching press carried out in track body bottom surface can reach this kind effect, and it is strong to bear load force, thereby guaranteed work high above the ground people's safety.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is the vertical view of the utility model embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2, a kind of high-altitude fall arrest shown in Figure 3 C shape guide rail, include track body 1, track body 1 includes bottom surface 11 and is symmetrically set in the row of the falling L side 12 of 11 both sides, bottom surface, the bottom surface 11 of track body 1 is provided with the deck 14 of bolting hole 13 and projection, only it has opening 2 with track body 1 on one side to described deck 14, the forward part 141 of deck 14 is rectangular substantially, and along track body 1 longitudinal stretching, its rear section 142 is tapered substantially, one end of rear section 142 is connected with forward part, and remainder is connected with track body 1.
In the utility model embodiment, the bottom surface 11 of described track body 1 is through forming deck 14 after the punching press, the general shape of deck 14 is half goblet shape, make deck 14 form stressed of being triangle, deck 14 is subjected to having four edges after the punching press, its forward part 141 is the working end, be provided with opening 2 between the limit 143 at this place, working end and the track body 1, being the cambered surface transition between its excess-three limit 144 and the track body 1 is connected, the stress surface that is arranged so that deck 14 like this becomes big, can to bear load also just bigger, guaranteed work high above the ground personnel's safety.
Described track body 1 uses bolt to be fixed on the construction by the bolting hole 13 that is provided with on it, with the supporting use of adaptive catching device.
Claims (2)
1, a kind of high-altitude fall arrest is with C shape guide rail, include the track body, described track body is provided with the deck of bolting hole and projection, it is characterized in that: only it has opening with the track body on one side to described deck, the forward part of deck is rectangular substantially, and along track body longitudinal stretching, its rear section is tapered substantially, one end of rear section is connected with forward part, and remainder is connected with the track body.
2, high-altitude according to claim 1 fall arrest is with C shape guide rail, it is characterized in that: described deck has four edges, its front portion is divided into the working end, be provided with opening between the limit at this place, working end and the track body, the deck rear section has three limits, is the cambered surface transition and is connected respectively with between the track body.
