The utility model discloses thereby the hookup of different diameter steel reinforcement cages is adapted to the hookup of hookup location of adjustable horizontal pole and longitudinal bar, and the symmetry sets up four jibs on the hoist and passes through the vertical reinforcing bar of threaded sleeve connection steel reinforcement cage, has improved steel reinforcement cage installation accuracy and security.
Description
Technical Field
The utility model relates to a bridge pile foundation construction technical field, concretely relates to after pile foundation pore-forming, to the hoist of downthehole hoist and mount steel reinforcement cage of stake.
Background
The pile foundation is the most main atress component of bridge construction, is formed by concrete and steel reinforcement cage combined action, and it is downthehole that the stake is transferred to the steel reinforcement cage after the pile foundation pore-forming, then the pile foundation concreting. At present common bridge pile foundation steel reinforcement cage is transferred and is adopted wire rope direct system on steel reinforcement cage, then lifts by crane and transfers through the crane, and the biggest advantage of this method is that the expense is low, but steel reinforcement cage transfers the positioning accuracy control degree of difficulty big, transfers the phenomenon that causes steel reinforcement cage to warp easily to heavier major diameter steel reinforcement cage, influences pile foundation quality.
for solving the problem that the major diameter steel reinforcement cage transferred the existence, often adopt two shaped steel welded cross hoists to set up a hoisting point at the end of every shaped steel, lift by crane through the vertical reinforcing bar of hoisting point connection steel reinforcement cage and transfer, this method transfers positioning accuracy and controls easily, but a hoist can only be applicable to the steel reinforcement cage of a diameter and transfers, and the suitability is poor, and cross hoist structure atress is complicated, transfers factor of safety low.
Disclosure of Invention
The utility model aims to provide a can guarantee that the steel reinforcement cage transfers the quality to the problem that the in-process exists is transferred to present pile foundation steel reinforcement cage to applicable hoist of transferring in different diameter steel reinforcement cages is provided.
The technical scheme of the utility model as follows:
The utility model provides a hoist suitable for different diameter steel reinforcement cages are transferred, its characterized in that: the frame comprises two horizontal rods which are horizontally arranged and are parallel to each other and two longitudinal rods which are horizontally arranged and are vertical to the horizontal rods, wherein the frame is shaped like a Chinese character 'jing', the two horizontal rods and the two longitudinal rods are respectively provided with a plurality of screw holes along the longitudinal direction of the rods, and the horizontal rods and the longitudinal rods are connected through the screw holes by bolts; each cross rod is longitudinally provided with a sliding groove, two vertical hanging rods which can slide along the sliding groove in a reciprocating manner penetrate through the sliding groove, the upper end of each hanging rod penetrates through a base plate on the top surface of the cross rod and is limited at the top of the base plate by being screwed with a nut, and the lower end of each hanging rod extends to a certain length below the cross rod and is screwed with a threaded sleeve; two lifting lugs are symmetrically welded on each longitudinal rod, and the two lifting lugs on each longitudinal rod are respectively connected with two ends of a lifting rope.
The utility model has the advantages that: all be provided with a plurality of bolt holes on the horizontal pole of hoist and the vertical pole, can adjust the hookup location of horizontal pole and vertical pole as required to the hoist and mount of different diameter steel reinforcement cages are adapted to. The symmetry sets up four jibs on the hoist, and the jib lower extreme passes through the vertical reinforcing bar of threaded sleeve connection steel reinforcement cage, screws up threaded sleeve and just can carry out the steel reinforcement cage and transfer the operation, simple structure, and the operability is strong, can effectively protect steel reinforcement structure to increase steel reinforcement cage's overall stability, can not lead to steel reinforcement cage slope phenomenon because of the plane atress inequality during hoist and mount, guarantee steel reinforcement cage's straightness that hangs down, improved steel reinforcement cage installation accuracy and security.

Detailed Description
As shown in fig. 1 and 2, the utility model comprises a framework shaped like a Chinese character jing formed by connecting two horizontal rods 1 which are horizontally arranged and parallel to each other and two vertical rods 2 which are horizontally arranged and perpendicular to the horizontal rods, wherein a plurality of screw holes 3 are respectively arranged on the two horizontal rods 1 and the two vertical rods 2 along the longitudinal direction of the rods, and the horizontal rods 1 and the vertical rods 2 are connected by bolts 4 through the screw holes; each cross rod 1 is longitudinally provided with a sliding groove 5, two vertical suspension rods 6 which can slide along the sliding groove in a reciprocating manner penetrate through the sliding groove 5, the upper end of each suspension rod 6 penetrates through a backing plate 7 on the top surface of the cross rod and is in threaded connection with a nut 8, the upper end of each suspension rod 6 is limited at the top of the backing plate 7, and the lower end of each suspension rod 6 extends to a certain length below the cross rod 1 and is in threaded connection with a threaded sleeve 9; two lifting lugs 10 are symmetrically welded on each longitudinal rod 2, and the two lifting lugs 10 on each longitudinal rod are respectively connected with two ends of a lifting rope 11.
the utility model discloses during the implementation, horizontal pole 1 can adopt the preparation of limbs channel-section steel, leaves certain clearance as spout 5 on the horizontal pole between two channel-section steels.
as shown in fig. 3 and 4, when the utility model is used, the distance between the two transverse rods 1 and the distance between the two longitudinal rods 2 are adjusted to be not larger than the diameter of the reinforcement cage 12 according to the diameter of the reinforcement cage 12 to be hoisted as required, and the screw holes 3 at proper positions are selected to connect the transverse rods 1 and the longitudinal rods 2 by bolts; the lengths of the two lifting ropes 11 are adjusted to be consistent, the lifting ropes 11 are lifted by the lifting hooks 13 of the lifting machine to a certain height, the horizontal rods and the longitudinal rods of the lifting device are kept horizontal, the two lifting rods 6 on the horizontal rod 1 of the lifting device are slid to be symmetrical, the lifting rods 6 on the two horizontal rods 1 are connected with 4 symmetrical vertical ribs on the steel reinforcement cage 12 through threaded sleeves 9, and then the steel reinforcement cage is lifted by the lifting machine integrally and is placed in a pile hole.
