Description

A kind of conveyor specially used for movable platform

Technical Field

The utility model relates to the technical field of railway cargo loading, and more specifically to a special conveyor for a movable platform.

Background Art

At present, when loading and unloading cars (trains) from flat ground, a ramp with a forklift is usually used; loading cars (trains) requires the use of a ramp to put the goods on the ground and then use the ramp to load them, which is inefficient, and there are safety hazards when forklifts climb up and down the ramp. In particular, during train transportation, cars are used to pick up goods and load them onto trains, and then they are loaded back into cars for delivery after arrival, which requires frequent docking operations. Fixed high platforms can facilitate operations, but high platforms cannot be built at every reverse loading and unloading point. First, the investment is large and uneconomical; second, the types of operations are limited after the high platform is built; and third, time constraints prevent the ability to quickly achieve reverse loading and unloading.

The existing patent is a mobile loading and unloading platform, and the patent authorization number is CN 206203504 U. It has the advantages of not being restricted by the site, convenient transportation, self-powered and movable, and convenient for loading and unloading goods on and off mechanical equipment.

However, in the patent authorization number CN 206203504 U, the front driving wheel is connected to the hydraulic motor and the steering cylinder through a fork assembly, and a main lifting mechanism is arranged under the two wing plates. The main lifting mechanism includes a lifting bracket and a second lifting cylinder. The second lifting cylinder controls the extension and retraction of the lifting bracket. Due to the limited length of the secondary inclined platform, the length extending into the platform is limited, which leads to great limitations in the process of cargo loading and unloading. Therefore, we propose a movable platform-specific conveyor to solve the above-mentioned problems.

The maximum lifting height is 2m, and it can be freely raised and lowered according to the height of the platform, thereby improving the applicability. The total length of the machine is 21.5m, and the tail end conveying mechanism can extend into the platform 13m, which is conducive to loading and unloading of goods and reduces limitations.
