In order to better illustrate the effect of using the end beam damping device for the shore crane sling, experimental analysis before and after the shore crane sling is installed on the device is carried out, and detailed explanation is given below.
The normal damper block thickness is about 14.70cm, but the thickness of the damper block after aged wear is less than this value. When the thickness of the shock absorption block reaches 14.30cm, the shock absorption block can only be scrapped. When the device is not installed, the time from normal to abandonment is less than 4 years. If the device is installed, the service life of the damping block can be prolonged by one to two years. The price of each damping block is 6000 yuan, each shore bridge crane is provided with 4 damping blocks, the service life of each damping block is prolonged by two years, and 15 years are taken as a period. If the end beam damping device of the shore crane lifting appliance is not used within 15 years, the damping block needs to be replaced for 4 times; the end beam damping device of the shore crane sling only needs to be replaced for 2 times. The cost saved by each quay crane spreader is then: (4-2) × 4 × 6000 ═ 48000 (yuan). Therefore, 3200 cost is saved for each shore crane lifting appliance every year on average, and the economic benefit is greatly improved. In addition, after the device is used, the times of replacing the damping block are reduced, and other costs, such as the cost of replacing parts, the cost of equipment downtime, the cost of electricity and oil for shutdown, are reduced.
The end beam damping device for the shore bridge lifting appliance has the following advantages:
1. the operation is safe and convenient, the fault occurrence rate of the shore bridge lifting appliance is reduced, and the safety is improved.
2. The service life of the shock absorption block is prolonged.
