Problems solved by technology

At present, the operator must go to the site to manually confirm whether the unloading trolley is in place, etc.; due to poor recovery of converter gas, gas may leak to the high-level bunker platform, and the temperature of the storage platform during converter production is as high as 50-60°C. There is a lot of dust, and the site environment is extremely harsh, which is not suitable for personnel to stay for a long time; the steelmaking production pace is relatively fast, and the maintenance time is relatively tight. Once the positioning of the trolley fails, normal feeding cannot be performed, which will affect the entire steelmaking production

Embodiment Construction

[0023] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0024] Such as Figure 1 to Figure 7 As shown, the present invention discloses a control method for a multi-group silo unloading trolley, comprising the following steps:

[0025] 1. Safety protection: such as figure 1 , the left and right limit positions are installed on both sides of the track, use the "closed point", input the PLC system signal as "1", and use the "green" small circle on the HMI screen of the host computer to indicate that the signal is "1", when unloading When the corresponding stopper on the trolley touches the limit or a limit fault occurs, the PLC system detects that the limit signal is "0", which is indicated by a small "red" circle on th...

Abstract

The invention discloses a method for controlling a dump cart for multiple groups of stock bins. According to the method, limiting switches are installed at the two sides of a cart track respectively for safety protection, and an encoder is installed on a cart driven wheel to record the cart traveling path; on the traveling path of the cart, a cart position verifying device is installed in the front of each group of stock bins for position verification, a bin position indicating device is installed on a feed inlet of each stock bin, and a set of limiting switch and position indicator lights is installed on each of the two sides of the feed inlet of each stock bin; a system automatically confirms whether a discharge outlet of the cart is accurately positioned at the feed inlet of each stock bin, and whether the discharge outlet of the cart is aligned with the feed inlet of each stock bin is monitored through a video monitoring device installed on the cart, so that it is ensured that the cart is right in place and whether a stock bin is full and whether materials are spilled out during feeding are found in time; when the cart is not positioned correctly, the manual fine adjustment mode can be adopted to enable the cart to be quickly adjusted to be in place, so that it is ensured that the cart reaches the corresponding stock bin quickly and accurately, the working intensity of operation staff is relieved, and meanwhile, production efficiency and production safety are improved.

Description

technical field [0001] The invention relates to a silo unloading trolley, in particular to a control method for a multi-group silo unloading trolley. Background technique [0002] At present, the raw materials required for steelmaking in the steelmaking plant reach the high-level silo through the underground silo through the belt feeding system and the unloading trolley, and each group of silos has 10 to 14 silos. In the process of daily raw material transportation, there are many kinds of raw materials, large conveying volume, many raw material bins, relatively small feeding openings of bins, and very little space between bins. Unloading trolleys are prone to inaccurate bin positions and easy mixing of raw materials. Material spillage, etc. During the feeding process, there is a long distance for raw materials to go from the underground silo to the high-level silo through the belt feeding system. It will take a while for the raw materials to reach the high-level silo. When...
