[0035] Embodiment 1

[0036] As Figure 1 shown, a reinforcing cage fast connecting device, comprising a first half circular arc structure 1 and a second half circular arc structure 2 connected by a hinge structure 5, forming an inner cavity when closed; the inner cavity is conical at the upper part, with a trumpet mouth upward and a narrow pointed part downward, to facilitate the rapid positioning of the upper reinforcing cage main reinforcement. The inner cavity is cylindrical at the lower part, reserving a position for the threaded sleeve of the lower reinforcing cage main reinforcement. The conical lower part is provided with a platform, narrowing the cylindrical upper part, to avoid the threaded sleeve penetrating through the entire connecting device. The first half circular arc structure 1 and the second half circular arc structure 2 are provided with a lock catch structure 3 on the side away from the hinge structure, stably placing the two half circular arc structures of the connector above the sleeve.

[0037] The cylindrical lower part of the inner cavity is provided with an anti-skid thread 6 for connecting the reinforcing sleeve.

[0038] The outer walls of the first half circular arc structure 1 and the second half circular arc structure 2 are narrowed at the upper part, and are cuboid at the lower part, to facilitate stacking, transportation and on-site clamping, and also to be aesthetically pleasing.

[0039] The outer wall of the first semicircular structure 1 and the second semicircular structure 2 is provided with a holding handle 4, so that the operator can conveniently hold and move the device, improve the construction efficiency, and reduce the operation difficulty.

[0040] As shown in the drawings, Figure 2 The hinge structure 5 comprises a bolt part provided on the upper part of the first semicircular structure 1 and a corresponding insertion hole part on the upper part of the second semicircular structure 2. The bolt part and the insertion hole part are provided on the outward protruding part of the upper part of the first semicircular structure 1 and the second semicircular structure 2. The opening formed by the first semicircular structure 1 and the second semicircular structure 2 avoids leaving a too large gap, which causes the upper reinforcement cage to be mistakenly inserted or clamped in the opening gap.

[0041] The pin of the bolt part is downward, and the hole of the insertion hole part is upward. The bolt can be smoothly inserted into the insertion hole. If the pin of the bolt part is upward, and the hole of the insertion hole part is downward, the bolt is prone to fall off, and further causes the high-altitude operation accident.

[0042] As shown in the drawings, Figure 3 The clasp part is provided on the plane formed by the first semicircular structure 1, and the setting plane of the clasp part of the second semicircular structure 2 is kept coplanar. The clasp part is provided on the same plane, which can reduce the difficulty of alignment, facilitate the mutual cooperation between the ring hooks, and also reduce the possibility of loosening.

[0043] The locking structure 3 in the embodiment comprises a clasp part provided on the lower part of the first semicircular structure 1 and a corresponding clasp hook part on the upper part of the second semicircular structure 2. The clasp part comprises a lock seat, a push piece and a clasp ring; the push piece is hinged to the lock seat, and the push piece is connected with the plane of the lock seat when the push piece is locked; the clasp ring is connected with the clasp hook part when the clasp ring is locked; and the clasp ring is made of elastic material.

[0044] The first semicircular structure 1 and the second semicircular structure 2 are made of light and rigid alloy material, which is suitable for high-altitude operation, convenient to carry, and has the rigidity required for bearing the reinforcement locking.

[0045] The device structure size of the utility model is designed according to the reinforcement and sleeve size specified in the relevant specification, has good universality, can realize multiple project turnover and repeated use, and has good economy.

[0046] Specific use principle:

[0047] The lower reinforcement cage is positioned and fixed;

[0048] The connecting device is installed on the main reinforcement in four directions of the lower reinforcement cage, and the number of connecting devices is symmetrically arranged according to the requirement, and is not less than 4 at least. The locking buckle structure 3 of the connecting device is opened, the position is adjusted from the gap between the reinforcements, the anti-skid thread 6 in the cavity of the connecting device is aligned with the sleeve on the main reinforcement, the first semicircular structure 1 and the second semicircular structure 2 of the connecting device are combined and locked with the locking buckle device 3, and the connecting device is stably placed on the sleeve;

[0049] The crane hoists the upper reinforcement cage to the space above the pile position and slowly lowers, when the upper reinforcement cage is lowered to the position close to the lower reinforcement cage, the operator holds the upper reinforcement cage and guides the main reinforcement in the corresponding position to fall into the horn mouth of the connecting device;

[0050] The main reinforcement of the upper reinforcement cage falls into the horn mouth and contacts the sleeve on the main reinforcement of the lower reinforcement cage, that is, the lowering is in position, at this time, the upper and lower reinforcement cages are accurately positioned, and are stably kept due to the temporary fixing effect of the connecting device;

[0051] The sleeves on the main reinforcement where the connecting device is not arranged are sequentially and symmetrically rotated to the predetermined position, and the preliminary connection of the upper and lower reinforcement cages is completed;

[0052] The connecting device is sequentially opened, the locking buckle device 3 is opened, and the connecting device is taken down, the remaining sleeves are screwed, and the connection of the upper and lower reinforcement cages is completed.

[0053] As described above, the stability of the reinforcement cage in the hoisting state is ensured, the object impact is avoided, the high efficiency of the quick connecting device also reduces the operation time of the operator exposed to the crane operation range, and the safety risk is reduced. The horn mouth structure of the utility model can guide the upper reinforcement cage to smoothly fall into the target position in the vertical lowering process, realize the accurate positioning of the upper and lower reinforcement cages, ensure the verticality of the reinforcement cage, ensure the smooth screwing of the sleeve to complete the connection, effectively avoid the deformation problem caused by the difficulty in screwing the sleeve and the eccentric force of the reinforcement cage, and the use of the device can significantly reduce the disturbance to the pile hole in the construction process, avoid the hole collapse phenomenon, and ensure the construction quality. The utility model realizes quick locking and quick dismounting through the left and right opening and closing structure and the hinge and locking connection mode, so that the steel reinforcement connection point is quickly connected, the construction time is significantly shortened, and the work efficiency is improved.
