Description
Technical field
The utility model relates to a kind of work high above the ground and uses fixture, the high hook of hanging low usefulness of particularly a kind of work high above the ground safety belt.
Background technology
Up to now, upkeep operation all belongs to work high above the ground on equipment such as the outdoor breaker of transformer station, isolating switch and transformer, should take the anti-high-altitude safety measure of falling by regulation.But do not have suitable safety measure on present breaker, isolating switch and the transformer, often be difficult to find the fixedly position of safety belt, have to adopt high-altitude operation vehicle to make the mooring points of safety belt, perhaps take the lantern frame and fasten the safety belt.Particularly take the lantern frame, the cost height of wasting time and energy does not say that the operation of installing/dismounting derrick remains work high above the ground; There is potential safety hazard equally, because, in practical operation; The fixing means that the operating personnel adopts is directly safety belt to be fixed on the derrick arm, and safety belt can only be fixed on position, operating personnel underfooting, has violated the low principle of using of high extension; If safety belt is fixed on parallel with the operating personnel; Belt length will lose buffer distance, falls hitting the derrick body with huge inertia in case the operating personnel slips, and causes personal injury most probably; Safety belt loses due safety effect, so the low drawback of hanging high usefulness that uses of seat belts never rationally solves.Under actual conditions, it is low with requiring that the crossbeam arm above the targets such as suspension breaker satisfies high extension, still because operating personnel's working face of living in and crossbeam are out of reach, more can't the safety belt hook be fixed on the crossbeam with hand, also can only feed on fancies.
Therefore, need a kind of safety belt hooking device to fix, realize the high low usefulness of hanging to satisfy its crossbeam with the target top.
The utility model content
The purpose of the utility model provides a kind of safety belt hook, and this hook can realize that safe ready is connected and the length of safety belt is convenient for changing again by aid and eminence fixing point, satisfies high low the using of hanging.
The utility model safety belt hook is achieved in that
A kind of safety belt protection hook; Comprise the safety belt perforation on coupler body, jam plate, lock rod spring, locking bar, locking bar locating hole and the coupler body, said locking bar locating hole is arranged on coupler body lower end relative position, and said locking bar penetrates from locking bar locating hole lower end; Said lock rod spring is enclosed within on the locking bar; The locking bar top is passed spring and is connected with jam plate, pushes up to the hook top along the axial ray of lock rod direction at the acting force of the spring lower locking plate, realizes locking states.
For jam plate more effectively is coupled with hook, said jam plate is provided with and links up with the coupling aperture that bill shape size adapts with the relative position of hook, and during with the hook locking states, the hook bill passes the further stable coupling of this coupling aperture enforcement.
Stretch for making things convenient for jam plate to do to come and go along the axial ray of lock rod direction, sliding eye can be set on jam plate, this sliding eye is enclosed within on the coupler body parallel with axial ray of lock rod, and sliding eye slides supporting the connection with coupler body.
For guaranteeing that jam plate non-migration angle slides up and down along coupler body is smooth and easy, the shape of said sliding eye is polygonal, and the shape of said coupler body cross section and sliding eye is complementary, and said polygonal limit number is greater than three.Fairly perfect safety belt hook is such; Comprise the safety belt perforation on coupler body, jam plate, lock rod spring, locking bar, locking bar locating hole and the coupler body, said locking bar locating hole is arranged on coupler body lower end relative position, and said locking bar penetrates from locking bar locating hole lower end; Said lock rod spring is enclosed within on the locking bar; The locking bar top is passed spring and is connected with jam plate, pushes up to the hook top along the axial ray of lock rod direction at the acting force of the spring lower locking plate, realizes locking states.Its characteristics also are: more effectively be coupled with hook for making jam plate, said jam plate is provided with and links up with the coupling aperture that bill shape size adapts with the relative position of hook, and during with the hook locking states, the hook bill passes the further stable coupling of this coupling aperture enforcement; Stretch for making things convenient for jam plate to do to come and go along the axial ray of lock rod direction, sliding eye can be set on jam plate, this sliding eye is enclosed within on the coupler body parallel with axial ray of lock rod, and sliding eye slides supporting the connection with coupler body; For guaranteeing that jam plate non-migration angle slides up and down along coupler body is smooth and easy, the shape of said sliding eye is polygonal, and the shape of said coupler body cross section and sliding eye is complementary, and said polygonal limit number is greater than three.
For making locking bar have characteristics rational in infrastructure, that cooperation is stable, installation is firm and easy to use; The shape of locking bar adopts cylindric; At the locking bar upper linker screw thread being set implements to be threaded with jam plate internal thread or nut; Flexible end in the locking bar bottom is provided with boss conveniently to grasp and to prevent that locking bar integral body from passing from locating hole, and locking bar and locating hole are implemented to be slidingly matched.
The utility model safety belt hook is to use like this:
At first the safety rope that has clasp of Len req is hung in the safety belt perforation on the hook, penetrate rifle top handgrip with common electrical work industry with earth connection then and catch the locking bar bottom or be called telescope tab, press and penetrate the rifle bottom and shrink handle grip moving lock bar and shrink; The jam plate of closed state breaks away from hook and is opening; Lift opening link that hook forms opening and hang on the portal crossbeam of equipment top or on the solid member, press at last and penetrate rifle bottom trip push button with penetrating rifle again, penetrate rifle top handgrip and unclamp; Penetrating rifle just breaks away from locking bar; The axial ray of lock rod direction ejects locking bar in the reaction force acts lower edge of lock rod spring, with the coupling of hook tip, forms the locking guard mode; Realized the high requirement of hanging low usefulness of safety belt, and scope of activities is not limited to.Only need shrink locking bar and just can make hook be opening and extract to get final product when removing hook with penetrating rifle.
The beneficial effect of the utility model: the utility model hook is proceeded from the reality; Be skillfully constructed; Except that the general character that can satisfy other safety belt hook secure fixation safety belt; More can rely on existing instrument that hook is hung on the perhaps solid member of the too late equipment top portal crossbeam of common hook staff, realize the high low usefulness of hanging.
