Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; either directly or indirectly through intervening media, or through the communication between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-2, the present invention provides a technical solution: vertical hoist of precast concrete pipe, including lifting rod 3, the outside cover of lifting rod 3 is equipped with slip ring 8, the top of slip ring 8 and the outside cover that is located lifting rod 3 are equipped with rings 1, L shape buckle 2 is installed to rings 1's lower terminal surface, L shape draw-in groove 9 with the supporting use of L shape buckle 2 is seted up at slip ring 8's top, and lifting rod 3's bottom swing joint has a plurality of jack-up connecting rods 7, the equal swing joint in top of a plurality of jack-up connecting rods 7 has shrink connecting rod 4, the top and the slip ring 8 swing joint of shrink connecting rod 4, equal swing joint has cambered surface fagging 5 on jack-up connecting rod 7's the lateral wall.

In this embodiment, preferably, the outer side walls of the arc supporting plates 5 are all provided with anti-slip layers 6.

In this embodiment, preferably, the number of the lifting links 7 is three, and the three lifting links 7 are uniformly arranged around the lifting rod 3.

In this embodiment, it is preferable that the center of the sliding ring 8 and the center of the hoisting rod 3 are on the same axis.

The utility model discloses a theory of operation and use flow: the lifting appliance adopts the principle that the lifting appliance is placed in the concrete prefabricated pipe 10, the pipe wall is supported by the dead weight of the prefabricated pipe, the prefabricated pipe is lifted, and the lifting appliance and the prefabricated pipe clamp are firmer when the weight of the prefabricated pipe is larger;

as shown in fig. 2, when the hanger is used, the hanger is lifted and placed into the precast concrete pipe 10, the hook of the crane drives the hanging ring 1 and the lifting rod 3 to move upwards, the force is transmitted to the lifting connecting rod 7, the lifting rod 3 moves upwards to drive the bottom end of the lifting connecting rod 7 to move upwards, so that the included angle between the contraction connecting rod 4 and the lifting connecting rod 7 becomes smaller and smaller, and meanwhile, the cambered supporting plate 5 expands outwards until the anti-slip layer 6 on the cambered supporting plate 5 is attached to the inner wall of the precast concrete pipe 10, so as to support and lift the precast concrete pipe 10, and then the crane can move the precast concrete pipe to a required place;

unhooking process: with L shape buckle 2 and the 9 blocks of L shape draw-in groove, rings 1 and slip ring 8 linkage this moment, then upwards mentions rings 1, can make slip ring 8 rebound, and the contained angle between shrink connecting rod 4 and the jack-up connecting rod 7 is bigger and bigger this moment, and cambered surface fagging 5 is inwards shrunk simultaneously, and the inner wall contact of prefabricated pipe 10 of antiskid layer 6 no longer with the concrete on the cambered surface fagging 5 can be mentioned the hoist and break away from prefabricated pipe 10 of concrete.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
