Abstract
The utility model relates to a C-shaped groove catching device, which comprises a casing (1) and a rotating part (2). The utility model is characterized in that the fixed end (14) of the rotating part (2) is movably connected with the casing (1) through an axle center (9), while a draw-in gear (4) perforating the bottom of the casing (1) is an active end (15) is formed integrally on the mating side of a C-shaped guiding rail, the draw-in gear (4) cooperates a fixture block (8) on the C-shaped guiding rail, one side of the active end (15) pulled by a safety belt connecting coil is established with a curve seam (6) perforating the rotating part (2).
Description
Technical field:
The utility model relates to fall arrest lifesaving technical field of safety devices, refers in particular to a kind ofly to be used for work high above the ground personnel with belt under the situation of flip-flop action, C shape groove catching device that can automatic falling-proof.
Background technology:
Known; power transmission and transformation in power system; telecommunication; industries such as chemical industry all have work high above the ground; in building field; the construction of skyscraper; safeguard; maintenance also often relates to ascend operation; if there is not reliable falling-proof safety device; safety code then can be implemented; and cause the accident in the ascend operation to give birth to frequently; though China's power industry regulation; ascend operation must not lose the safety belt protection; and in fact; common safety belt can't be brought into play its effect on shaft tower; therefore, at this technical problem, numerous designers put in the research and design of falling-proof safety device; when the catching device that uses in the work high above the ground now meets accident as if the operating personnel; if the operating personnel is not earlier to layback tenesmus again, will glide earlier one section distance of catching device just can cooperate braking with guide rail, but this braking is not often because of there being to cushion the certain injury of health generation to the operating personnel.
Summary of the invention:
The purpose of this utility model is in order to solve the shortcoming of above-mentioned prior art, a kind of C shape groove catching device reliable, that have pooling feature of braking to be provided.
For achieving the above object, the technical scheme that the utility model provides is: a kind of C shape groove catching device, it includes housing, pulley and tumbler, the stiff end of tumbler flexibly connects by axle center and housing, and the side that movable end cooperates towards C shape guide rail is one-body molded the dop that runs through housing bottom arranged, this dop cooperates with fixture block on the C shape guide rail, and movable end is subjected to a side of safety belt connection cord pulling to have the curve that runs through tumbler to stitch.
Be connected with spring between the top of tumbler and the housing.
After adopting technique scheme; a moment that the operating personnel meets accident; spring on the catching device will act at once the dop on the tumbler is produced; dop can block the fixture block on the guide rail automatically earlier simultaneously; operating personnel under the side meeting quilt of safety belt pulling weighs down on the moving block then be pulled away from the main body of moving block; will produce cushioning effect in this process, effectively protect operating personnel's personal safety.
Description of drawings:
Fig. 1 is that the dop of the utility model catching device screws out the outer profile front view of housing bottom;
Fig. 2 is the dop of the utility model catching device cutaway view that catching device and C shape guide rail cooperate when not blocking fixture block;
Fig. 3 is the dop of the utility model catching device cutaway view that catching device and C shape guide rail cooperate when blocking fixture block;
Fig. 4 is that the dop of the utility model catching device screws out the outer side view of housing bottom;
Fig. 5 is that the dop of the utility model catching device screws out the outer vertical view of housing bottom;
Fig. 6 be the tumbler of the utility model catching device by stretch bending after the vertical view that cooperates of catching device and C shape guide rail.
The specific embodiment:
Elaborate the utility model below in conjunction with accompanying drawing:
Shown in accompanying drawing 1～accompanying drawing 6, the stiff end 14 of the tumbler 2 of this catching device is connected with housing 1 by axle center 9, tumbler 2 can be rotated around housing 1, and movable end 15 has a dop 4 towards a side of C shape guide rail 3 is one-body molded, the bottom of housing 1 has through hole 10, dop 4 can pass this through hole 10, movable end 15 is subjected to a side 5 of safety belt connection cord pulling to have C shape curve seam 6, because the existence of C shape curve seam 6, weigh down following time the operating personnel, utilize the process of metal tension bending (as Fig. 6) to produce buffering.The top of housing 1 has through hole 11, on tumbler 2, have the counterbore 12 corresponding with through hole 11, be crimped with spring 7 by screw 13 between this counterbore 12 and the through hole 11, and stamp out fixture block 8 (as Fig. 2, Fig. 3, Fig. 6) on the C shape guide rail 3, when the operating personnel is dropped, offer dop 4 on the catching device and block fixture block 8 on the C shape guide rail 3, realize anti-drop function.In addition, this catching device carries out counterweight to catching device and spring 7 elastic force when design, under normal conditions, the dop 4 of catching device is contracted in the housing 1 (as Fig. 2), the effect that spring 7 is subjected to catching device gravity is compressed, operating personnel's tumbler 2 when upwards climbing is subjected to the pulling of safety belt connection cord and slides, when meeting accident, at a moment of the pulling that loses the safety belt connection cord, spring 7 will promote tumbler 2, dop 4 stretches out the housing 1 outer fixture block 8 (as Fig. 3, Fig. 6) that blocks, and stops the tenesmus of catching device.
Claims (2)
1. C shape groove catching device, it includes housing (1) and tumbler (2), it is characterized in that: the stiff end (14) of tumbler (2) flexibly connects by axle center (9) and housing (1), and the side that movable end (15) cooperates towards C shape guide rail is one-body molded the dop (4) that runs through housing (1) bottom arranged, this dop (4) cooperates with fixture block (8) on the C shape guide rail, and movable end (15) is subjected to a side (5) of safety belt connection cord pulling to have the curve seam (6) that runs through tumbler (2).
2. a kind of C shape groove catching device according to claim 1 is characterized in that: be connected with spring (7) between the top of tumbler (2) and the housing (1).
