Description

Technical Field

[0001] The present invention relates to the technical field of automatic hook release for cargo lifting, and specifically to a rapid automatic release mechanism for cargo lifting; it can be widely used in places where manual hook release is required because the operator cannot reach the position during cargo lifting and release. Background Art

[0002] Currently, when lifting cargo, it is generally necessary to manually hook the cargo, and after the cargo is lifted to the designated position, it is also necessary to manually unhook it before the next cargo can be lifted; in one case, because the height difference between the cargo storage position and the lifting height is relatively large, the unhooking personnel need to follow back and forth, or multiple people are arranged at the lifting and storage positions to operate the hooking and unhooking, resulting in a slow production rhythm, increased work intensity, and increased labor costs; in another case, the cargo is tall and large, and it is difficult for personnel to climb up and down the cargo frequently, making it difficult to achieve manual hooking and unhooking. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the existing technology and provide a rapid automatic release mechanism for cargo lifting.

[0004] The technical solution provided by the present invention is: a rapid automatic release mechanism for cargo lifting, which is characterized in that it consists of a cylindrical seat, a threaded cone sleeve, a square wedge block, a spring, a sliding cone sleeve, and a load-bearing pin shaft; the cylindrical seat is the main body of the mechanism, a threaded cone sleeve is arranged in the central hole of the cylindrical seat, a load-bearing pin shaft is arranged on the threaded cone sleeve, a sliding cone sleeve is arranged on the load-bearing pin shaft, and the sliding cone sleeve and the threaded cone sleeve have the same outer shape and are arranged back to back; two square sliding guide grooves are symmetrically arranged at the lower part of the cylindrical seat; a square wedge block and a spring are respectively arranged in the two square sliding guide grooves at the lower part of the cylindrical seat, and the square wedge block is horizontally moved by the spring in the sliding guide groove; one end of the square wedge block is wedge-fitted with the conical surface of the threaded cone sleeve; when the cylindrical seat moves up and down, it drives the square wedge block to move downward and outward along the conical surface of the threaded cone sleeve.

[0005] Furthermore, the cylindrical seat, the square wedge block, and the spring are a set; the load-bearing pin shaft, the threaded cone sleeve, and the sliding cone sleeve are one set or multiple sets.

[0006] Further, when the cylindrical seat is controlled by the lifting device to sink, the square wedge moves downward and outward along the taper surface of the threaded taper sleeve. When the two square wedges move to the lower part of the threaded taper sleeve, they extend laterally under the action of the spring and support the bottom surface of the threaded taper sleeve. Lifting the cylindrical seat can lift the threaded taper sleeve together with the load-bearing pin shaft and the goods below to the required position. At this time, the goods cannot be automatically unhooked. When the cylindrical seat continues to sink, the square wedge passes over the large end of the sliding taper sleeve and abuts against its taper surface. When the cylindrical seat is lifted, the square wedge lifts the sliding taper sleeve. When the cylindrical seat is lifted further, the sliding taper sleeve fits against the threaded taper sleeve and stops moving. The square wedge moves outward and passes over the sliding taper sleeve to wedge with the threaded taper sleeve. Continuing to lift the cylindrical seat realizes the rapid automatic release of the lifting device and the heavy object below.

[0007] The beneficial effects of the present invention are as follows: The lifting device and the heavy object below can be quickly and automatically released. One set of the cylindrical seat, the wedge block and the spring is provided on the lifting device, and multiple sets of the load-bearing pin shaft, the threaded taper sleeve and the sliding taper sleeve can be provided and are manually assembled and connected to the goods in advance. When the goods are moved to the designated position, the load-bearing pin shaft is quickly disengaged from the cylindrical seat and can be left on the goods, realizing rapid automatic unhooking without the need to configure multiple people or manually move frequently to unhook, thereby improving production efficiency, reducing labor costs, reducing the labor intensity of personnel, and realizing automation.

[0010] For better understanding and implementation, the present invention will be described in detail below with reference to the drawings.

[0011] Such as Figure 1, 2 As shown in Figures 3, 4, 5, 6, 7, 8, and 9, a rapid automatic release mechanism for lifting goods is composed of a cylindrical seat 1, a threaded taper sleeve 2, a square wedge 3, a spring 4, a sliding taper sleeve 5, and a load-bearing pin shaft 6. The cylindrical seat 1 serves as the main body of the mechanism. Two square sliding guide grooves are symmetrically opened at the lower part of the cylindrical seat 1. The square wedge 3 and the spring 4 are respectively installed in the two square sliding guide grooves. The square wedge 3 is pushed horizontally by the spring 4 in the sliding guide groove. One end of the inclined surface of the square wedge 3 is wedged with the conical surface of the threaded taper sleeve 2 in the central hole of the cylindrical seat 1. The load-bearing pin shaft 6 is assembled on the threaded taper sleeve 2, and the sliding taper sleeve 5 is assembled on the load-bearing pin shaft 6. The sliding taper sleeve 5 has the same shape as the threaded taper sleeve 2, and the two are arranged back to back. The cylindrical seat 1 is controlled by the lifting device to sink. The square wedge 3 moves downward and outward along the inclined surface of the threaded taper sleeve 2. When the two square wedges 3 move to the lower end of the threaded taper sleeve 2, they horizontally extend under the action of the spring 4 and support the bottom surface of the threaded taper sleeve 2. At this time, lifting the cylindrical seat 1 can lift the threaded taper sleeve 2 together with the load-bearing pin shaft 6 and the goods below to the required position. When the cylindrical seat 1 continues to sink, the square wedge 3 passes over the large end of the sliding taper sleeve 5. At this time, when lifting the cylindrical seat 1, the square wedge 3 lifts the sliding taper sleeve 5. Continuing to lift the cylindrical seat 1, the sliding taper sleeve 5 fits against the threaded taper sleeve 2 to stop. The square wedge 3 continues to move outward and passes over the sliding taper sleeve 5 to wedge with the threaded taper sleeve 2. Continuing to lift the cylindrical seat 1 can realize the rapid automatic release of the lifting device and the heavy object below, without manual unhooking.

[0012] For the rapid automatic release mechanism for lifting goods of the present invention, in use, the cylindrical seat is fixed on the lifting device. One set of the cylindrical seat, the wedge, and the spring is provided on the lifting device. Multiple sets of the load-bearing pin shaft, the threaded taper sleeve, and the sliding taper sleeve can be set and manually assembled and connected to the goods to be lifted below in advance. Operate the lifting device to sink the cylindrical seat to align with the load-bearing pin shaft. When the square wedge extends to the lower end of the threaded taper sleeve, lift the load-bearing pin shaft and the goods. After moving to the designated position, the lifting device continues to sink the cylindrical seat. When the square wedge exceeds the large end of the sliding taper sleeve, the lifting device and the cylindrical seat are lifted. When the sliding taper sleeve rises to be back-to-back and tightly attached to the threaded taper sleeve, the square wedge continues to rise beyond the large end of the sliding taper sleeve and wedges with the conical surface of the threaded taper sleeve. The load-bearing pin shaft and the goods are disconnected from the cylindrical seat and the lifting device and can remain on the goods. Repeat lifting the next batch of goods. There is no need for manual participation in the process, saving labor costs and improving production efficiency.
