Abstract
A concrete pipe hoisting clamp belongs to the field of concrete prefabricated parts and comprises a clamping ring (9), a rope (3), an open rigging screw fastener (7), self-tightening pliers (6) and a hoisting beam (2). The clamping ring is open, and two convex edges (11) are arranged at the opening; the outer circumference of the snap ring is provided with a hook ear which is equally divided with the opening. The three-fork or four-fork shaped hanging beam is provided with a rope on a fork branch and is hung with a self-clinching pliers, and the jaw clamps the convex edge at the opening of the snap ring; the ropes on the other fork branches are connected with the open rigging turnbuckles and hook the hook ears.
Description
The utility model relates to a kind of concrete prefabricated element apparatus field, is applicable to the concrete pipe lifting jig of carrying in the production of concrete prefabricated tubing or the installation process.
At present, precast concrete manufacturer is for displacement, the carrying of concrete pipe, mostly needs the trustship ring (being to take off at the end) with the concrete pipe same model, and need be with bindings such as ropes; Especially in lifting, entrucking, or site construction is when installing, and binding, dismounting are very bothersome, also not firm, cause man power and material's very big waste.
The purpose of this utility model is exactly to provide a kind of simple and easy concrete pipe lifting jig that can carry, install concrete pipe without the trustship ring for concrete pipe manufacturer or construction and installation building site.
The utility model is by snap ring, rope, constitute from clencher, open type wire tensioner and hanging beam.Living by the snap ring of lifting concrete pipe in order to cover (card), is the ring of an opening; Lifting lug with the opening equal distribution is arranged on the excircle of snap ring, and the lip limit on snap ring opening part both sides is the convex edges of turning over laterally, and the convex edge can be for clamping from the clencher jaw.Hanging beam is trident or four fork-shapeds, and its each fork branch goes up captive joint or movable sleeve hangs with rope, and wherein the lower end of a rope is connected with the ring that lifts that is connected from two arms of clencher; The lower end of all the other each bar ropes is connected with the coupling link of open type wire tensioner respectively.The hook of each open type wire tensioner other end hooks the lifting lug on the snap ring excircle respectively.When the concrete pipe need be shifted or lift by crane, snap ring cover (card) is lived concrete pipe, from the opening convex edge that the jaw of clencher is clamped snap ring, elevator machinery tangles the suspension ring of this jig hanging beam center, the concrete pipe can be sling.
Snap ring in the utility model is the ring of the opening of the similar stirrup made by a roll of steel plate.The steel plate of its also available two semicircular arc will be coupled together in the middle of it by hinge, and is the ring of opening that can free opening and closing.
Hanging beam in the utility model can be three fork-shapeds, also can be four fork (cross) shapes, thereby the hoist point of corresponding with it snap ring excircle is also different.When hanging beam is three fork-shapeds, weld on the snap ring excircle, and with the lifting lug of snap ring opening equal distribution be two; When hanging beam was four fork (cross) shapes, then the lifting lug with the opening equal distribution was three.
The utility model has the advantages that simple in structurely, easy to use, safety, reliable saves time, laborsaving.The concrete pipe that can satisfy different model without the trustship ring aborning or the lifting in the construction and installation, carrying, entrucking and installation.
Accompanying drawing is a structural representation of the present utility model
Embodiment: as shown in the drawing, being the annular arrangement stirrup of a single radial cut in order to entangle the peripheral snap ring (9) of concrete pipe (4), also can be two openings that the semi arch steel plate constitutes that coupled together by hinge, and annulus stirrup that can free opening and closing; It is the convex edges (11) of turning over to periphery that its opening (10) is located two lip limits, so that clamp from the jaw of clencher (6).On the circumferential periphery of its circular stirrup of snap ring (9), be welded with lifting lug (8) with opening (10) equal distribution.If hanging beam (2) is three fork-shaped structures, then the lifting lug (8) on the snap ring (9) is two; If hanging beam (2) is four fork (cross) shape structures, then the lifting lug (8) on the snap ring (9) has three.Hanging beam shown in the accompanying drawing (2) is that four fork-shapeds are cruciform construction.The Zhou Bianchang of snap ring (9) is slightly less than the girth of concrete pipe (4) of being sling.In order to clamp the opening convex edge (11) of snap ring (9), the upper end of its two arms is connected with chain (12) or gyration, lifts ring (5) and is connected with chain (12) or gyration from the jaw of clencher (6).Angle equalization between the fork branch of three fork-shapeds or four fork-shaped hanging beams (2) can be made of square steel or pipe or round steel pipe, and the hanging beam in the accompanying drawing (2) is that square steel tube constitutes.Suspension ring (1) are equipped with on the top, center of hanging beam (2), for the usefulness of hanging of elevator machinery.Each fork branch of hanging beam (2) goes up captive joint or movable sleeve hangs with rope (3).Rope (3) can be steel rope, nylon rope or coir rope.Wherein have the lower end connection of a rope (3) to lift ring (5), remaining rope (3) lower end connects the upper end coupling link of open type wire tensioner (7) respectively; The lower end hook of each open type wire tensioner (7) hooks the lifting lug (8) on snap ring (9) excircle respectively.The length of rope (3) can be regulated the height unanimity that it is sling by open type wire tensioner (7).
When operation, snap ring (9) cover (card) is lived concrete pipe (4) lower end external diameter, and will bite the opening convex edge (11) of snap ring (9) from the jaw of clencher (6).The hook of elevator machinery hooks the suspension ring (1) on the hanging beam (2), slings slowly,, the opening convex edge (11) of snap ring (9) is stung tightly voluntarily with slinging and strengthen snap-in force from clencher (6) jaw.Because the excircle of snap ring (9) and concrete pipe (4) clamps, its contact friction force is greater than the weight of concrete pipe (4), the concrete pipe (4) of can slinging, thus realize displacement, the carrying of concrete pipe (4) in producing, or the lifting during construction and installation.
Claims (3)
