Description

Technical Field

[0001] The utility model relates to the technical field of port engineering equipment, in particular to a tooling device for disassembling a gantry crane trolley chain. Background Art

[0002] Gantry cranes are commonly known as yard cranes. They are special machinery for large-scale specialized container yards, mainly used for loading and unloading standard containers. This type of crane is not only suitable for the yards of container terminals, but also for special container yards. Its metal structure is like a door-shaped frame, with two legs installed under the load-bearing main beam. It can walk directly on the track on the ground or on tires. It has the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility. It is widely used in port cargo yards. When all gantry cranes are tire-type gantry cranes, the gantry crane's trolley travel mechanism is mainly composed of a motor, a coupling, a reducer, and a sprocket chain drive. The chain drives the wheel axle to achieve trolley travel.

[0003] However, when the chain breaks, deforms, or reaches the replacement cycle, it must be replaced. Each gantry crane has multiple trolley chains, and chain replacement is stressful. There are two traditional processes for replacing trolley chains: 1. Drive the gantry crane trolley to a specific position so that the trolley chain head appears in a convenient position for disassembly, and then use a series of tools such as pliers, through-hole screwdrivers, hammers, etc. to disassemble the trolley chain head, but the whole process is often uncertain. For example, when the gantry crane trolley cannot move or the chain head is difficult to disassemble, it sometimes takes a long time and still cannot successfully disassemble the chain; 2. Open flame operation, use open flame to cut the chain as a whole, but there is a risk of open flame, and the process is cumbersome. Regardless of which plan is adopted, the process of disassembling the chain is dangerous and has poor mobility, resulting in reduced efficiency.

[0004] Therefore, it is urgent to develop a solution for disassembling the chain of the gantry crane trolley, which can make the disassembly of the chain of the gantry crane trolley safer and more efficient. Summary of the invention
