Background
The most common work of loading on land at bulk terminals is the hopper type bulk loader and the box type bulk transport truck with a canopy (shown in fig. 1, in which the truck is not covered) which are used in a through-type lane work mode. Now, the following is explained:
1. the hopper type bulk cargo loader is a loader with a frame structure and comprises the following structural elements:
1) a funnel: the bulk cargo container is an inverted regular quadrangular pyramid-shaped bulk cargo container, is positioned above the charging machine and is used for temporarily storing bulk cargo grabbed by a grab bucket of the bulk cargo crane from a bulk cargo ship, and a square discharge port is arranged below the bulk cargo container.
2) A charging platform: the middle part of the charging machine is provided with a walking channel, a railing and an equipment supporting structure, and the center of the charging machine is provided with a square hole which is matched with a discharge hole of the hopper.
3) Blanking gate: the device is arranged on a discharge port of the funnel, and the feed port is rectangular and has constant length; the gate is provided with a gate control rod and is used for controlling the position and the width of the feed opening, so that the position and the flow of actual feeding are controlled. The gate lever extends and is fixed to a solid portion of the loading platform, which is operated by an operator located on the loading platform in a conventional manual operating mode.
4) Door leg: four column type vertical supporting legs constitute rectangular frame, support funnel and charging platform.
5) A traveling passage: and a channel between the two pairs of door legs and the ground below the loading platform, wherein one side of the channel is provided with an inlet for a bulk cargo transport truck to enter the lower part of the loading platform and complete loading.
2. Bulk transport truck: the box type truck is characterized in that a rectangular space is formed inside a container, and after entering the lower part of a blanking platform through a traveling channel of a bulk cargo loader, blanking is received from a blanking gate and transportation is completed.
The typical charging process of the funnel type bulk loader comprises the following steps:
1. entering a field: the bulk cargo transport truck enters the lower part of the blanking platform through a traveling channel of the loader;
2. aligning the first charging: the loading operator commands a driver of the bulk transport truck to carry out first loading alignment, so that the proper position of the front part of the carriage is aligned with the blanking gate;
3. charging for the first time: after the first charging alignment is finished, an operator opens the discharging gate to the central position by using the control rod, the middle part of the carriage in the left and right directions is charged (initially charged), and the height of the material pile is continuously observed in the charging process, so that the height of the material pile is prevented from exceeding the height of a carriage baffle; after the middle part is loaded, the blanking gate is respectively opened to the left and right positions, the left side and the right side are subjected to filling, and the height of the material pile also needs to be continuously observed in the filling process;
4. aligning subsequent charging: after the first charging is finished, an operator determines the position of a carriage for next charging according to the shape of the material pile for first charging and instructs a truck driver to finish alignment;
5. and (3) subsequent charging: after the subsequent loading alignment is completed, the operator uses the control rod to complete initial loading and additional loading. The subsequent loading alignment and loading process are repeated until the carriage is basically full;
6. aligning the last charging: when the stockpile is paved on the bottom of the whole carriage, an operator determines whether the last charging is needed according to the stockpile condition, and if so, the operator instructs a truck driver to complete the last alignment.
7. And (3) charging at the last time: after the last time of loading alignment is completed, the operator uses the control rod to complete initial loading and supplement, and the unloading is required to be ensured not to be scattered outside the rear baffle of the carriage.
By adopting the charging operation flow, the following defects and risks exist:
1. the loading speed and the loading quality depend on the operation skill and the responsibility of an operator of the blanking gate, and if the skill is sparse or the responsibility is not strong, the actual loading effect is poor, and adverse effects such as underload, overload, overflow and the like are caused;
2. the quality of the charge is also dependent on the cooperation of the charging operator with the truck driver. If the truck driver is not matched, the alignment time is too long or the alignment is not accurate, the adverse effects of overlong actual charging time, poor loading effect and the like can also be caused;
3. there is no effective communication means between the loading operator and the truck driver, and at present, interaction can be carried out only by original modes such as knocking metal objects, and the operation coordination effect is uncertain and depends on the on-site exertion of the two parties;
4. the charging operation site has serious dust emission and severe working environment, and the physical health of charging operators is damaged;
5. the bulk crane has large impact force when feeding the hopper, the whole structure of the charging machine has aging and damage risks, and once the impact force exceeds the critical value, the bulk crane may collapse during feeding the hopper, so that the personal safety of a feeding operator is endangered.
