Magnetic distribution device for scrap iron adsorption in hydraulic system

Abstract

The invention relates to a magnetic distribution device for scrap iron adsorption in a hydraulic system. The magnetic distribution device comprises two groups of front hook arms, two groups of rear hook arms, permanent magnets and rollers. The magnetic distribution device is characterized in that the end parts of the front hook arms and the rear hook arms are hinged to form two groups of clampingjaw units capable of being opened and closed, and the free ends of the two groups of clamping jaw units are connected through a connecting shaft to form a clamping jaw frame; shaft bulges are oppositely arranged on the inner sides of the clamping jaw units inwards, the shaft bulges are symmetrically arranged by taking a hinge shaft as a symmetric center, rotatable sleeves are installed on the shaft bulges where the front hook arms are located, and rotatable screw sleeves are installed on the shaft bulges of the rear hook arms; screw rods are installed in the sleeves and the screw sleeves, blocking pieces are arranged at the ends, close to the sleeves, of the screw rods, and threads on the screw rods are matched with the screw sleeves; and the screw rods are rotated to control the clampingjaw frame to be opened and closed. The magnetic distribution device can be freely implemented in a narrow space, the permanent magnets can be easily transferred to a target position, the whole use process is labor-saving, convenient and rapid, and the placement position is accurate.

Description

technical field [0001] The invention relates to the field of transformation of hydraulic system equipment, in particular to a magnetic distribution device for iron filings adsorption in a hydraulic system. Background technique [0002] The role of the hydraulic system is to increase the force by changing the pressure. A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary components (accessories) and hydraulic oil. During the operation of the hydraulic system, due to The friction between the moving parts of the hydraulic equipment (such as the piston and the hydraulic rod) will inevitably produce iron filings particles, and the longer the use time, the more iron filings will be generated. This problem is currently unavoidable; The iron filings particles are brought into the circulating oil circuit with the circulation of the hydraulic oil, and they tend to accumulate over time. The accumulated iron filings will c...

Problems solved by technology

[0005] First, because the outer wall of the hydraulic equipment (the oil pressure of the hydraulic oil is higher) is thicker, the permanent magnet can only be effective if the NdFeB strong magnet is used. Ordinary magnets are weak in magnetism, although they can be tightly adsorbed on the hydraulic equipment. , but the magnetic force passing through the outer wall of the hydraulic equipment has been attenuated a lot, and the adsorption capacity is too poor, which makes the permanent magnet must use NdFeB strong magnetism to have a better effect; and the magnetic force of NdFeB strong magnetism is very strong , once adsorbed on the shell surface of the hydraulic equipment, it is difficult to adjust its position (under the premise of strong magnetic force, the outer wall of the hydraulic equipment is due to the adhesion of dust, oil, and sundries, which makes the friction force very large ), for example, in order to achieve the best possible effect, the permanent magnet needs to be adsorbed at the center of the bottom of the hydraulic equipment, so that most of the iron filings can be adsorbed and fixed. However, because the ground clearance of the hydraulic equipment is too low, only Firstly, the permanent magnet is adsorbed on the edge of the bottom of the hydraulic equipment, and then pushed at the center of the king, but it is very difficult to push due to the excessive magnetic force

[0006] Second, due to the small distance from the ground and the narrow operating space of the hydraulic equipment, it is very inconvenient for the designer to move the position of the permanent magnet, and because the magnetic force is too strong, it is difficult for the technician to apply force when moving the position , it is impossible to concentrate and release all the power like in a large space, which makes the permanent magnet with strong magnetic force even more immobile, so there are great difficulties in installation
