Description

Technical Field

[0001] This invention relates to the field of lifting device technology, and in particular to a claw-type quick self-detaching lifting device. Background Technology

[0002] Existing hoisting equipment typically uses belts or wire ropes to tether the steel cylinder and then lifts it directly. After installation, untying the wire rope is cumbersome, which not only consumes a lot of time, but also, since it uses a single rope for hoisting, if the installation is not tight and the rope is untied, the steel cylinder is prone to falling and causing a safety accident. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a claw-type quick self-detaching lifting device to solve the problems in the background art mentioned above.

[0004] The technical problem solved by this invention is achieved by the following technical solution: A claw-type quick-release lifting device includes a fixed plate, a motor, a drive gear, a rack, a chain, a telescopic connecting rod, a mounting frame, and four-part claws. The motor and drive gear are respectively mounted on the fixed plate, with the drive gear connected to the motor's output shaft. One end of the rack is connected to the drive gear, and the other end passes through the fixed plate and connects to the chain. One end of the telescopic connecting rod is mounted on the lower end of the fixed plate, and the other end is mounted on the mounting frame. The four-part claws are mounted on the mounting frame. The chain passes through the telescopic connecting rod and the mounting frame before connecting to the four-part claws. The four-part claws consist of four drive components.

[0005] In this invention, the fixing plate is provided with mounting holes for placing the fixing plate in a fixed position, which makes it less likely to fall off.

[0006] In this invention, the telescopic connecting rod has a hollow structure, which facilitates the passage of the chain.

[0007] In this invention, the drive assembly includes an upper connecting rod, a G-shaped connector, and an auxiliary connector. The upper end of the upper connecting rod is mounted on a mounting bracket, and the lower end of the upper connecting rod is configured with a pin groove structure. The left end of the G-shaped connector is provided with a pin hole for connecting with the pin groove of the upper connecting rod, and the right end of the G-shaped connector is provided with an auxiliary pin hole for connecting with the auxiliary connector. The chain is connected to the G-shaped connector and the auxiliary connector respectively.

[0008] In this invention, the G-shaped connector is provided with a lifting through hole, which can be used to fix the chain with the object suspended in it.

[0009] In this invention, the G-shaped connector and the auxiliary connector are respectively provided with arc-shaped hooks.

[0010] Beneficial effects: This invention uses a motor to drive a four-part claw to achieve rapid self-unhooking, which is simple to install and effectively reduces installation time. In addition, the use of rope and hook for lifting makes it less likely for objects to fall, effectively eliminating safety hazards. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of a preferred embodiment of the present invention. Detailed Implementation

[0012] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0013] See Figure 1 A claw-type quick self-detaching lifting device includes a fixed plate 1, a motor 2, a drive gear 3, a rack 4, a chain 5, a telescopic connecting rod 6, a mounting frame 7, and four-part claws 8. The motor 1 and drive gear 3 are respectively mounted on the fixed plate 1, and the drive gear 3 is connected to the output shaft of the motor 1. One end of the rack 4 is connected to the drive gear 3, and the other end of the rack 4 passes through the fixed plate 1 and is connected to the chain 5. One end of the telescopic connecting rod 6 is mounted on the lower end of the fixed plate 1, and the other end of the telescopic connecting rod 6 is mounted on the mounting frame 7. The four-part claws 8 are mounted on the mounting frame 7. The chain 5 passes through the telescopic connecting rod 6 and the mounting frame 7 and then connects to the four-part claws 8. The four-part claws 8 consist of four drive components.

[0014] In this embodiment, the fixing plate 1 is provided with mounting holes for placing the fixing plate 1 in a fixed position, so that it is not easy to fall off.

[0015] In this embodiment, the telescopic connecting rod 6 has a hollow structure, which facilitates the passage of the chain 5.

The upper end of the upper connecting rod 9 is mounted on the mounting bracket 7, and the lower end of the upper connecting rod 9 is configured with a pin groove structure. The left end of the G-shaped connector 10 is provided with a pin hole for connecting with the pin groove of the upper connecting rod 9, and the right end of the G-shaped connector 10 is provided with an auxiliary pin hole for connecting the auxiliary connector 11. The chain 5 is connected to the G-shaped connector 10 and the auxiliary connector 11 respectively.

[0017] In this embodiment, the G-shaped connector 10 is provided with a lifting through hole, which can be used to fix the chain with the object suspended in it.

[0018] In this embodiment, the G-shaped connector 10 and the auxiliary connector 11 are respectively provided with arc-shaped hooks.

[0019] In this embodiment, before use, the fixing plate 1 is installed in a fixed position (here, the fixed position is only the position for installing the fixing plate 1, which can be a position on the moving object where the fixing plate 1 can be installed), and then the motor 1 is started. The motor 1 drives the drive gear 3 to rotate, and the drive gear 3 drives the rack 4 to drive the chain 5 to tighten the four-part claw 8 on which the object is suspended, thereby moving the object to the destination. After reaching the destination, the motor 1 is turned off, the drive gear 3 stops running, and the rack 4 drives the chain 5 to relax, thereby quickly unhooking the object.
