Description
Technical field
The U-shaped snap ring of using when the utility model relates to a kind of steel structure hoisting operation, the particularly U-shaped snap ring of a kind of improved steel structure hoisting, belong to the U-shaped snap ring that can realize on the ground crane hook and weight rapid unhooking.
Background technology
In Steel Structure Installation engineering, the installation of the large-scale components such as steel column, girder steel mainly adopts crane lifting.Workman is first by steel rope and snap ring fixation for steel column or girder steel, and after waiting steel column, steel girder erection in place, crane loosens hook, is unclamped the bolt of each snap ring by workman, makes to lift steel rope separated with weight, and then lifts next part weight.In common engineering construction, often need by lodge cat ladder or install safety hanging cradle additional steel rope is carried out to dismounting, the upper and lower hanging ladder of workman or hanging basket are aloft work, and safety precaution is low, greatly dangerous, and installation effectiveness is not high yet.CN201376836Y discloses the self-unloading snap ring that a kind of hoisting and hanging is used, by U-shaped snap ring main body, formed, feature is that the open end in U-shaped snap ring main body is respectively equipped with hole clipping, outside 1 hole clipping is fixed with spring tube, in spring tube, be connected with the pin with positioning round table, one end of pin, through 2 hole clippings of U-shaped snap ring body openings end, is connected with hole clipping movable contact; The other end of pin is connected with spring tube outlet movable contact through the termination of spring tube, and the termination of pin is fixed with tail ring; Between positioning round table and spring tube outlet, be provided with spring.Above technology is for the utility model after lifting operation installation in position, and how workman directly drags out the pin of U-shaped snap ring safely (under dragging), realizes the rapid unhooking of lifting steel rope and the member that hangs on ground, do not provide concrete guidance program.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of improved steel structure hoisting U-shaped snap ring, use this U-shaped snap ring to implement after steel lifting component operation installation in position, workman directly drags out the pin of U-shaped snap ring safely on ground, realize the rapid unhooking of lifting steel rope and the member that hangs, easy and simple to handle, thus manpower saved, improve installation effectiveness.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
The U-shaped snap ring of a kind of improved steel structure hoisting, there is U-shaped body of clasp, pin, its technical scheme is that it is circular hole that described U-shaped body of clasp is respectively arranged with dark hole directly over two terminations of its open end, in each dark hole, be all provided with the gripping mechanism spacing to pin, the side of described two terminations of U-shaped body of clasp is provided with respectively pin-and-hole, described pin is arranged in pin-and-hole, each gripping mechanism all has the decorative pearl on top of an official cap (ball of the bottom of being located at dark hole, steel ball), be located at the adjustment screw that the Yu An hole, upper end in dark hole is threaded, be located at the decorative pearl on top of an official cap and adjust the stage clip between screw, described pin is provided with two annular grooves, the decorative pearl on top of an official cap in each gripping mechanism stretches out a part from the bottom in dark hole and falls in a groove corresponding with it and pin is spacing.
In technique scheme, the tail end of described pin is preferably with a circular hole, is preferably connected with the rope that pin is departed from from pin-and-hole in this circular hole, i.e. (carefully) safety rope.The peripheral contour shape of each groove in the section plane of the axis through pin is preferably circular arc.
Use the utility model to implement lifting operation to steel structure, under the double action of lifting weight gravity and gripping mechanism, pin is firmly blocked, and can not get loose.After installation in position, workman pulls rope on ground, rope drives pin separated with gripping mechanism, thereby pin is departed from from pin-and-hole, can realize the rapid unhooking (decylization) of lifting steel rope and the member that hangs, and need not or install safety hanging cradle additional by lodge cat ladder, steel rope is carried out to dismounting, improved installation effectiveness and safety factor, and there will not be the danger of workman's high falling.Compare with the self-unloading snap ring that the disclosed hoisting and hanging of CN201376836Y is used, the utility model is different from its structure, the utlity model has gripping mechanism, the rope that workman connects by the afterbody of traction pin on ground, under rope tractive force and the effect of (telescopic) stage clip, the decorative pearl on top of an official cap just can not be stuck in groove, and pin can be easy to depart from from pin-and-hole, and then realize the rapid unhooking that lifts steel cable and weight, operate easier.And its pin of self-unloading snap ring that the disclosed hoisting and hanging of CN201376836Y is used can not depart from from hole clipping.
In sum, with the utility model, implement after steel lifting component operation installation in position, workman directly drags out (under dragging) by the pin of U-shaped snap ring on ground with (carefully) safety rope safely, realized the rapid unhooking of lifting steel rope with the member that hangs, easy and simple to handle, thereby saved manpower, improved installation effectiveness.
