Description

A detection method, detection device and cover opening device for an intelligent ore-separating sample bucket

technical field

The invention mainly relates to the technical field of ore separation, in particular to an intelligent ore separation sample bucket opening detection method, a detection device and a cover opening device.

Background technique

At present, the intelligent sample barrel opening system includes a support plate, a lifting cylinder and a suction cup. The support plate is fixed on the fixed platform, and the lifting cylinder is fixed below the support plate; A lock body is installed on the barrel to control the horizontal movement of the lock head to realize the locking and unlocking of the sample barrel; one end of the lifting cylinder is equipped with a suction cup, which follows the cylinder to complete the up and down movement. The suction cup is equipped with an electromagnet, and the corresponding barrel cover is built iron block. When the electromagnet on the suction cup is energized, the electromagnet will attract the iron block on the lid, and the lifting cylinder will lift up, thus completing the action of opening the lid.

When opening the lid, it is usually necessary to detect the opening status, but there are many factors that lead to the unsuccessful opening of the lid: (1), the pressure of the suction cup is not on the same level as the lid, so only one end is stressed; (2) . Insufficient magnetism of the electromagnet leads to insufficient suction; (3) Unsuccessful unlocking of the lid causes the sample barrels to be sucked up together.

The current method for detecting the opening of the lid is as follows: a pair of photoelectric cross-radiation switches are installed on one side of the bung, and the photoelectric cross-firing switches are positioned on the same level as the bung when the lid is not opened. When the lid is normally sucked up, no lid signal will be detected. However, this kind of detection can only be used for the above (1) and (2) cases where the opening of the cover is unsuccessful, and it cannot be judged for the case (3). As for the detection of the sample barrel being sucked up together, the reason is that the lid was not successfully opened and the barrel was sucked up together with the lid. The harm caused in this case will be destructive. If the sample bucket is lifted and cannot be detected in time and effectively, the slewing mechanism will continue to move and cause structural collision and damage. At present, the lifting of the sample barrel includes the following three situations: (1) The locks on both sides are not opened, causing the sample barrel to be lifted vertically; (2) The left lock is not opened, causing the sample barrel to be lifted to the right; (3) ) The right lock head is not opened, causing the sample barrel to be lifted to the left. After the sample barrel is lifted, it is loose and falls down, causing the sample barrel to tilt or roll over, and the state is unpredictable. At present, the traditional solution is generally to add a proximity switch at the bottom or side of the sample bucket for induction, and the induction signal disappears when the sample bucket is lifted. However, the disadvantage of this solution is that no matter if the sensor switch is added at the bottom or on the side, proximity switches must be added in multiple directions, front, rear, left, and right, in order to reliably detect the various states of the sample barrel being lifted, which will not only increase the cost , the identification time will also be lengthened, because the proximity switch of the switching value output has only two signal states 1 and 0, which cannot capture the gradual and gradual change process in the middle, which increases the difficulty of identifying risks in advance. When using this solution in actual use, the bottom of the sample bucket needs to be lifted at least 3cm before it can be identified, and if the sample bucket is lowered at this height, the original positioning reference will change, so manual intervention is required to deal with the problem, and automation cannot be realized run. Therefore, it is necessary to predict in advance that the bucket will be lifted before the sample bucket is lifted or when the bucket is lifted to a small height. It is possible to avoid failures and realize unattended operation by taking identification and treatment before the failure is about to occur or before it occurs.
