Description

Technical Field

[0001] This utility model relates to the field of lifting and hoisting equipment technology, specifically to a chain lifting device that is easy to disassemble. Background Technology

[0002] Chain lifting equipment is a key piece of equipment in industrial hoisting, logistics transportation and construction. It is widely used in scenarios such as lifting, handling and fixing heavy objects. Its core function is to transmit tension through the combination of chain and hook to achieve safe and reliable load bearing. However, traditional chain lifting equipment has many defects in structural design, which leads to problems such as high maintenance costs in actual use. Therefore, it is particularly important to develop a chain lifting equipment that is easy to disassemble.

[0003] Referring to a chain lifting device with CN217808263U, which is easy to disassemble, it includes a support ring, a slewing bearing mounted on the bottom surface of the support ring, the outer ring of the slewing bearing being fixedly connected to the support ring, a suspension part provided below the slewing bearing, the suspension part being fixedly connected to the inner ring of the slewing bearing, and a mounting frame mounted above the support ring via a connecting assembly. The support ring is equipped with an oiling component for adding lubricating oil to the slewing bearing. This chain lifting device, through its rational design, allows for quick installation and disassembly of the lifting device without the need for other tools, greatly improving convenience and enabling easy disassembly and replacement. The oiling component allows for the addition of lubricating oil when the lifting device rotates unevenly, ensuring normal rotation and reducing the impact on work. However, while this chain lifting device can be widely used, it typically only uses a mounting frame to support the suspended components, without any reinforcing components. This results in generally weak overall structural strength, failing to meet the intended requirements and requiring further improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a chain lifting device that is easy to disassemble, in order to solve the problem mentioned in the background art that although chain lifting devices can be used well, they usually only use mounting frames to support and place the suspended components, and the mounting frames are not equipped with reinforcing components, which makes the overall structural strength of the chain lifting device generally weak and difficult to achieve the intended purpose.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chain lifting device that is easy to disassemble, comprising a base plate, a rectangular frame at the top edge of the base plate, and uprights at the corners of the outer walls of the rectangular frame. A plurality of first reinforcing ribs are fixedly installed on the inner walls between adjacent uprights. A plurality of second reinforcing ribs are provided above the base plate, with both ends of the second reinforcing ribs fixedly connected to the inner walls of the uprights. A cross-shaped top frame is fixedly installed at the top of the uprights. A plurality of side connecting seats are provided on the outer walls of the cross-shaped top frames. An upper connecting frame is provided at the bottom of each side connecting seat. An oblique reinforcing rib is rotatably installed at the bottom of the upper connecting frame. A lower connecting frame is rotatably installed at the end of the oblique reinforcing rib away from the upper connecting frame, and the end of the lower connecting frame away from the oblique reinforcing rib is fixedly connected to the outer wall of the uprights.

[0006] Preferably, each of the upper outer walls of the support frame is provided with a mounting base, which is arranged in an L-shape to accommodate the locking bolts.

[0007] Preferably, locking bolts are installed on both sides of the bottom end of the mounting base. The top of the locking bolt extends through to the top of the cross-shaped top frame. The top of the locking bolt passes through the cross-shaped top frame and is screwed into the installation platform of the lifting equipment so as to install and connect the entire lifting device.

[0008] Preferably, a circular seat is installed at the center of the bottom end of the substrate, and a stud is installed on the internal thread of the circular seat. The top of the stud extends above the rectangular frame. The suspension ring can be disassembled by screwing the stud out to the outside of the substrate.

[0009] Preferably, the bottom end of the stud extends to the outside of the substrate and is fixed with a nut. The top end of the nut touches the bottom end of the circular base. A cap hole is provided at the center of the bottom of the nut so that the stud can be screwed through the nut.

[0010] Preferably, a suspension ring is rotatably mounted on the outer wall of the circular base. The suspension ring is U-shaped, which allows for the suspension and hoisting of objects.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the easily disassembled chain lifting device not only improves the overall structural strength of the chain lifting device, but also improves the convenience of maintenance of the chain lifting device, and achieves the purpose of easy installation and connection of the chain lifting device;

[0012] (1) By setting several first reinforcing ribs and second reinforcing ribs, the four uprights are reinforced. Also, because the side connecting seat and the uprights are reinforced by the upper and lower connecting frames, the cross-shaped top frame and the uprights are reinforced, thereby improving the overall structural strength of the chain lifting device.

[0013] (2) By using a tool to unscrew the nut from the cap hole area, the stud can be unscrewed to the outside of the base plate, and the round seat can be quickly removed from the bottom of the base plate to achieve the purpose of quick disassembly of the suspension ring, thereby improving the convenience of chain lifting maintenance.

[0014] (3) By tightening the locking bolt, the upper end of the locking bolt passes through the mounting base and the cross-shaped top frame in sequence and is screwed into the installation platform of the chain hoisting device. The chain hoisting device can be bolted and placed on the hoisting device, thereby achieving the purpose of easy installation and connection of the chain hoisting device. Attached Figure Description
