[0034] Please refer to Figures 1-4, an automatic hook - releasing device for a steel reinforcement cage sling provided by an embodiment of the present utility model includes a mounting seat 2 for accommodating a hook 1, a driving device 3 detachably arranged on the outer peripheral side of the mounting seat 2 and having a pin 4, and a sling assembly for hoisting the steel reinforcement cage detachably arranged at the lower part of the mounting seat 2. The pin 4 is used to insert into the hook 1.

[0035] The driving device 3 can drive the pin 4 to insert into or pull out of the hook 1 to realize the automatic hook - releasing of the hook 1. The mounting seat 2 can mount the driving device 3 and connect the sling assembly, eliminating the need for manual rotation of the tongue, thus having better safety.

[0036] As Figures 1-4 shown, the sling assembly includes a lifting lug plate 5 detachably arranged at the lower part of the mounting seat 2, a plurality of connecting members 6 obliquely arranged on the outer peripheral side of the lifting plate 7, and a lifting plate 7 arranged at the lower end of the connecting members 6. The lifting plate 7 is used for installing the steel reinforcement cage. The plurality of connecting members 6 connect the lifting plate 7 and the lifting lug plate 5 together, with firm connection, improving the hoisting stability. The lifting lug plate 5 is not connected to the steel reinforcement cage to avoid the deformation of the steel reinforcement cage.

[0037] As Figures 1-4 shown, the mounting seat 2 includes symmetrically arranged first mounting plates 202 and second mounting plates 203. The upper parts of the first mounting plates 202 and the second mounting plates 203 are spaced apart to form a mounting cavity 201. The lifting lug plate 5 is detachably arranged between the lower parts of the first mounting plates 202 and the second mounting plates 203. The first mounting plates 202 and the second mounting plates 203 are respectively provided with through - holes, and the pin 4 passes through the through - holes, with a simple and reasonable structure.

[0038] As Figures 1-4 shown, the lifting lug plate 5 is provided with an avoidance hole 501 axially penetrating it. The lower parts of the first mounting plates 202 and the second mounting plates 203 are detachably inserted with a stop shaft 8. The stop shaft 8 passes through the avoidance hole 501, and the stop shaft 8 abuts against the upper surface of the avoidance hole 501. Two semi - circular flange plates 9 are sleeved on one end of the stop shaft 8, and the flange plates 9 are detachably connected to the first mounting plates 202. The stop shaft 8 and the lifting lug plate 5 cooperate to block the lifting lug plate 5, and are detachably connected to the first mounting plates 202 through the flange plates 9. The flange plates 9 are flange - connected to the first mounting plates 202 by bolts, which is convenient for installation and disassembly.

[0039] As Figures 1-4As shown, the driving device 3 is a hydraulic cylinder. A hydraulic component 10 for driving the hydraulic cylinder is detachably arranged on the outer side of the first mounting plate 202. The hydraulic component 10 includes components such as a hydraulic pump, an oil tank, and a tubing, which are used to drive the hydraulic cylinder to work. Further, a housing 11 is detachably arranged on the outer peripheral side of the first mounting plate 202. The hydraulic component 10 is located inside the housing 11, and the housing 11 protects the hydraulic component 10. An electric control component (not labeled) is arranged on the outer side of the second mounting plate 203, which is used to control the start and stop of the hydraulic pump.

[0040] Further, an electric control box 12 is arranged on the second mounting plate 203 to protect the electric control component. The electric control box 12 is hinged with a cover plate 1201, which is convenient for the staff to open for maintenance. When in use, the cover plate 1201 is covered, so that the electric control component is not easily damaged.

[0041] As Figures 1-4 shown, one side plate 204 is respectively arranged on both sides of the upper part of the first mounting plate 202. The side plates 204 are respectively fixedly connected to the first mounting plate 202 and the second mounting plate 203. The side plates 204 can limit the lifting hook 1 and restrict the lifting hook 1 in the installation cavity 101, so that the lifting hook 1 will not move excessively, and the lifting stability of the lifting hook 1 is improved.

[0042] As Figures 1-4 shown, a first bending part 2021 and a second bending part 2031 that are bent outward are respectively arranged on the upper part of the first mounting plate 202 and the upper part of the second mounting plate 203. A third bending part 2041 that is bent outward is arranged on the upper part of the side plate 204. The first bending part 2021, the second bending part 2031, and the third bending part 2041 form an opening, so that the lifting hook 1 is more easily inserted into the installation cavity 201, and the first mounting plate 202, the second mounting plate 203, and the side plate 204 are not easily damaged.

[0043] As Figures 1-4 shown, a connecting beam 13 is fixedly arranged on one side of the lifting lug plate 5. The connecting beam 13 is made of an I-beam. The connecting beam 13 can connect another automatic hook release device to ensure the overall stiffness. The hanging plate 7 is lengthened, and two automatic hook release devices share one hanging plate 7. In this way, the two devices can be symmetrically matched to hoist larger steel reinforcement cages with good hoisting stability.

[0044] As Figures 1-4 shown, the connecting piece 6 is a steel column or a steel wire rope, which has a firm connection and improves the bearing capacity.
