The utility model discloses a device convenient for online maintenance of a bucket elevator, which comprises an outer shell, an oil recharging assembly is arranged on the inner side of the outer shell, and a monitoring assembly is arranged above the oil recharging assembly, and relates to the technical field of online maintenance of bucket elevators. According to the device facilitating online overhauling of the bucket elevator, through cooperative operation of the integrated monitoring assembly and the oil supplementing assembly, a closed-loop management system for chain state monitoring and dynamic lubrication is built, the device can monitor the tension of the chain in real time and synchronously feed back the tension to the control system, the control system controls the oil supplementing assembly, and the oil supplementing efficiency is improved. Compared with a traditional manual inspection mode, manual inspection frequency can be greatly reduced, shutdown maintenance time can be shortened, operation and maintenance efficiency can be remarkably improved, operation continuity of the bucket elevator and stability of the production rhythm are effectively guaranteed, meanwhile, the oil supplementing assembly can accurately control the oil quantity, and the oil supplementing efficiency is improved. And the conditions of insufficient oil injection and excessive oil injection are prevented.

This invention relates to a clamping method and fixture for gripping irregularly shaped products, specifically in the field of fixture control. The method includes: during assisted gripping, matching the rotation angle of the gripper jaws to the gripping point, and obtaining an auxiliary contour by comparing the gripping point with the product contour; defining the gripper jaws corresponding to the auxiliary contour as auxiliary grippers; adjusting the gripper jaws by the rotation angle, pressing the gripper jaws down against the product, first opening the gripper jaws for alignment, then closing the gripper jaws; stopping the auxiliary gripper jaws when a gripping signal is sensed; releasing an air bladder, inflating it at an inflation rate, and simultaneously recording the inflation contour, the pressure inside the bladder, and the pressure change rate of the bladder; stopping inflation when the pressure change rate is less than a reference change rate, and filling the air bladder with a solid filling medium; after filling with the solid filling medium, deflating the air bladder until the inflation contour matches the auxiliary contour, then stopping the deflating. This application achieves the effect of adaptive gripping of multiple irregularly shaped products with a single gripper.

The invention relates to the technical field of medical instruments, in particular to a bladder irrigation device for nursing, comprising: a portable box, one side of which is rotatably connected with a box cover; the mounting plate is fixedly connected to the interior of the portable box; the three-cavity catheter is arranged at the position of the portable box and used in cooperation with the portable box, and the upper end of a flushing pipe of the three-cavity catheter is communicated with a normal saline bag; the two peristaltic pumps are symmetrically and fixedly mounted on the two sides of the mounting plate respectively and used for extruding and pushing a flushing pipe and a drainage pipe of the three-cavity catheter. The two symmetrically-arranged peristaltic pumps are adopted to drive the flushing pipe and the drainage pipe of the three-cavity catheter respectively, according to the flushing requirement, the hydraulic power unit is adjusted and controlled to flexibly adjust and control the pressing and releasing states of the pump cores to the pipeline, and the controllable operation of independent pressurization in the flushing and drainage process is achieved; the system is suitable for various nursing scenes such as wards, emergency treatment and families, and the treatment safety and efficiency are improved.
