Description

Technical Field

[0001] The utility model relates to the technical field of equipment for disassembling and assembling a cylinder of a quay crane wheel clamp, in particular to a transport support device for disassembling and assembling a cylinder of a quay crane wheel clamp. Background Art

[0002] YLZ series hydraulic wheel clamp (hereinafter referred to as wheel clamp) is a new type of windproof brake device, which is widely used for windproof brake in working state of large and medium-sized cranes and port loading and unloading machinery and auxiliary windproof brake in non-working state. It is an advanced and efficient windproof brake product with hydraulic drive release, compact structure and small maintenance workload. The wheel clamp cylinder is an important part of the wheel clamp, and the disc spring is installed inside the wheel clamp cylinder. The disc spring is applied to the braked wheel through the piston rod and the brake arm to establish the specified braking torque for braking.

[0003] The wheel clamp cylinder is mainly composed of a cylinder body, a piston, a disc spring and a seal. The disc spring is made of spring steel and can withstand static loads, impact loads or dynamic alternating loads. Due to the long-term load state of the disc spring, fatigue cracking occurs, thus affecting the braking performance. The seal of the cylinder ages and leaks oil due to being in a working state for a long time. The quay crane is one of the important lifting equipment in the container terminal. When the disc spring and oil seal of the YLZ series wheel clamp cylinder of the quay crane are damaged, they must be replaced in time to avoid the hydraulic oil in the cylinder from leaking to the ground and causing environmental pollution.

[0004] The traditional method of replacing the YLZ series wheel clamp cylinder is to tie the wheel clamp cylinder with a nylon sling, then put on a steel pipe, two people lift the cylinder, and another person disassembles and installs it. Some wheel clamp cylinders on the quay crane are blocked by the trolley motor and brake on the other side, which makes it difficult to operate. The wheel clamp cylinder has a certain weight and a certain height from the ground. There is a safety hazard of falling and injuring people when lifting the cylinder manually. It takes 1-2 hours to replace a wheel clamp cylinder, which will increase maintenance time and labor costs. Long-term maintenance will also affect the equipment guarantee rate. Utility Model Content
