Abstract
The invention relates to a retractable safety protective device for work at heights. The device comprises a device casing, wherein a strap for being connected with the waist of a worker is fixed on the outer side of the device casing; a first rotating shaft, a second rotating shaft and a speed regulating mechanism are arranged in the device casing; an auxiliary rope winding wheel is mounted on the first rotating shaft and wound with an auxiliary safety rope, the outer end of the auxiliary safety rope directly extends out of the device casing, a main rope winding wheel is mounted on the second rotating shaft and wound with a main safety rope, and the main safety rope penetrates through the speed regulating mechanism and extends out of the device casing. With implementation of the technical scheme, the structure is simple, the deploying and retracting speed of the safety ropes is controlled through regulation of a distance between a speed regulating pulley and a fixed pulley, and then the lifting and dropping speed can be controlled automatically by the worker working at heights. The main rope and the auxiliary ropes are arranged to jointly guarantee safety of the worker working at heights.
Description
Technical field
The application relates to the safety rope that a kind of work high above the ground uses, and particularly relates to a kind of contraction type high-altitude operation safety protector with double protection structures.
Background technology
At present, the safety means that high-altitude uses comprise: safety belt, safety rope, safety rope is the back-up protection of safety belt.In the process of ascending a height, safety rope, at staff's easy whipping behind, if multilayer line, easily tangles, affects operating personnel and ascend a height by safety rope.Existing safety rope in use easily contacts with equipment on electric pole, thus has certain wearing and tearing, and the safety rope after wearing and tearing will reduce safety coefficient.Meanwhile, the rising or falling speed of existing safety rope relies on ground staff to regulate, and work high above the ground personnel can only passively accept, and cannot control voluntarily, there is certain potential safety hazard when work high above the ground.
Mostly be to control the stop formation of safety rope when high speed pull about the stretching structure of safety rope in prior art, and the folding and unfolding speed control structure of not mentioned control safety rope.
Summary of the invention
The object of the application is that proposing one can control rising or falling speed by work high above the ground personnel, the contraction type high-altitude operation safety protector that safety coefficient is high voluntarily.
The object of the application is achieved in that contraction type high-altitude operation safety protector comprises crust of the device; the waistband in order to be connected with operating personnel's waist is had at crust of the device extenal fixation; the first rotating shaft, the second rotating shaft and speed adjusting gear is provided with in described crust of the device; described first rotating shaft is equiped with auxiliary rope-winding wheel; it is wound with auxiliary security rope; the direct extending apparatus shell in auxiliary security rope outer end; described second rotating shaft is equiped with main rope-winding wheel; it is wound with main safety rope, main safety rope is through extending apparatus shell after speed adjusting gear.
Owing to implementing technique scheme, the application's structure is simple, by the adjustment of governor sheave with the spacing of fixed pulley, thus the folding and unfolding speed of control safety rope, and then rising or falling speed can be controlled voluntarily by work high above the ground personnel.The application arranges main rope and auxiliary rope, the common safety ensureing work high above the ground personnel.
Accompanying drawing illustrates: the concrete structure of the application is provided by following drawings and Examples:
Fig. 1 is the structural representation of contraction type high-altitude operation safety protector.
Legend: 1, movable pulley, 2, the outlet of main rope, 3, main safety rope, 4, auxiliary security rope, 5, the outlet of auxiliary rope, 6, assist rope-winding wheel, the 7, first rotating shaft, 8, waistband, 9, main rope-winding wheel, the 10, second rotating shaft, 11, fixed pulley, 12, chute.
Detailed description of the invention:
The application by the restriction of following embodiment, can not determine concrete embodiment according to the technical scheme of the application and actual conditions.
Embodiment: as shown in Figure 1, contraction type high-altitude operation safety protector comprises crust of the device, has the waistband 8 in order to be connected with operating personnel's waist at crust of the device extenal fixation.In described crust of the device, be provided with the first rotating shaft 7, second rotating shaft 10 and speed adjusting gear, described first rotating shaft 7 be equiped with auxiliary rope-winding wheel 6, it be wound with auxiliary security rope 3, the direct extending apparatus shell in auxiliary security rope 3 outer end.Described second rotating shaft 10 is equiped with main rope-winding wheel 9, it is wound with main safety rope 3, main safety rope 3 is through extending apparatus shell after speed adjusting gear.
Described main rope-winding wheel 9 and the second rotating shaft 10, the auxiliary torsion spring being all equiped with to make main rope-winding wheel 9 between rope-winding wheel 6 and the first rotating shaft 7, assisting rope-winding wheel 6 return.
Described speed adjusting gear comprises staggered movable pulley 1 and fixed pulley 11, and described movable pulley 1 and fixed pulley 11 projection section is in the horizontal plane overlapping.The crust of the device at movable pulley 1 place offers chute 12, and described movable pulley 1 can move up and down along chute 12, changes the spacing between fixed pulley 11, until contact.By movable pulley 1 and fixed pulley 11 to the pressure change of main safety rope 3, i.e. the folding and unfolding speed of the main safety rope 3 of adjustable.
Described movable pulley 1 rotates around an axle, and this axle outer end is by chute 12 extending apparatus housing, and inner close movable pulley 1 place is provided with terrace with edge, and this axle extension offers external screw thread, and is connected with lock nut.By this structure by lock nut and terrace with edge to the clamping of crust of the device, thus regulate arbitrarily, movable pulley 1 present position, location.
Described main safety rope 3, through the left outside side of fixed pulley 11, extends to movable pulley 1 right flank by between fixed pulley 11 and movable pulley 1, is finally stretched out by the main rope outlet 2 being opened in crust of the device upper end.
During use, operating personnel first adjusts spacing between fixed pulley 11 and movable pulley 1, can pull out main safety rope 3 be advisable with comparatively laborsaving, determines whether use auxiliary security rope 4 subsequently, if site environment is multilayer operation, then use according to site environment.Operating personnel, in the process of ascending a height, by main safety rope 3 and the connection of overhead hung contact, completes the security protection to operating personnel.By the connection of auxiliary security rope 4 with overhead hung node, strengthen the safety of operating personnel further.The application's structure is simple, only needs to be articulated in loins, by the use of two safety ropes, increases high-altitude working safety coefficient.
Above technical characteristic constitutes the most preferred embodiment of the application, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characteristic according to actual needs, meet the needs of different situations.
