Description

Technical Field

[0001] The present invention relates to the technical field of ferrographs, and particularly to a control system for a double - rotary ferrograph for oil - fluid detection of mining equipment. Background Art

[0002] A ferrograph is a new method for testing mechanical wear invented in the 1970s of the 20th century. It is a method that uses magnetic force to separate metal particles in oil fluid and arranges them on a substrate according to the particle size. It can not only read the relative concentration of large and small particles, but also further analyze the physical properties of the particles. The analysis process of a ferrograph generally includes four basic links: sampling, spectrum preparation, observation and analysis, and conclusion.

[0003] A Chinese patent with the publication number CN205679504U discloses a ferrograph, which includes a base, a bracket, and an annular waste - liquid collection tank. The bracket is vertically installed at the center of the base. A rotatable ring is arranged on the base with the bracket as the center. The ring is driven by a stepping first motor. A plurality of substrate - making devices are evenly distributed on the ring. The annular waste - liquid collection tank is installed on the base, below the lowest point of the substrate holder. An oil - sample tray and a cleaning - liquid tray are movably installed on the bracket. The protruding parts of the oil - sample tray and the cleaning - liquid tray are arranged alternately. The protruding parts of the oil - sample tray correspond to the positions of the substrate - making devices on the ring, solving the problem of low efficiency in making ferrograph films of the existing ferrograph.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1: A control system for a double - rotating ferrograph for detecting oil fluid of mining equipment, as Figure 1 , includes a base 1, two connecting columns 11 rotatably arranged at the upper end of the base 1, a magnetic head 13 for placing a substrate 12 is provided at the upper ends of the two connecting columns 11, a motor 14 for respectively driving the two connecting columns 11 to rotate is arranged in the base 1, and a control member for controlling the rotation speed of the connecting columns 11 is arranged in the base 1. The control member controls the rotation column to rotate at a preset speed within a preset time.

[0028] By controlling the rotation speed and operation time of the motor 14 through the control member, it is convenient to control the rotation speed of each substrate 12, so that when the same oil sample is detected simultaneously at the same rotation speed and time or during the next detection, the same rotation speed and time as those of the substrate 12 during the first oil sample detection can be controlled.

[0029] Embodiment 2: A cleaning system for a double - rotating ferrograph for detecting oil fluid of mining equipment, which can be applied to the above - mentioned Embodiment 1 or to the cleaning of the substrate 12 of other ferrographs, as Figure 2 and Figure 3, including a cleaning device arranged on the upper end face of the base 1 for dripping cleaning liquid onto the substrate 12. The cleaning device includes an L-shaped rotating rod 15 rotatably connected to the upper end face of the base 1. The vertical end of the rotating rod 15 is rotatably connected to the base 1, and the other horizontal end is located above the substrate 12. A dropper 151 is provided at the horizontal end of the rotating rod 15. The dropper 151 has openings at both the upper and lower ends. The two connecting columns 11 are on the same straight line. Two droppers 151 are provided at the upper end of the rotating rod 15, and each dropper 151 is located above its respective substrate 12. When the substrate 12 is rotating, the rotating rod 15 is rotated so that the dropper 151 is away from the substrate 12. When the substrate 12 needs to be cleaned, the rotating rod 15 is rotated so that the horizontal end of the rotating rod 15 is directly above the two substrates 12. At this time, the two droppers 151 are facing the substrates 12, facilitating the user to add cleaning liquid to the substrates 12 through the droppers 151.

[0030] Such as Figure 2 And Figure 3 , a liquid adding member for dripping cleaning liquid into the two droppers 151 is provided on the rotating rod 15. At this time, the setting of the liquid adding member facilitates adding cleaning liquid into the droppers 151.

[0031] Such as Figure 2 And Figure 3 , the liquid adding member includes a slide rail 152 provided at the upper end of the rotating rod 15. The slide rail 152 extends along the vertical portion of the rotating rod 15. A liquid adding bottle 153 for storing cleaning liquid is slidably connected to the slide rail 152. The upper end of the liquid adding bottle 153 has an opening. A sliding groove 154 for the liquid adding bottle 153 to slide is provided on the vertical portion of the rotating rod 15. At this time, the slide rail 152 communicates with the sliding groove 154, facilitating the liquid adding bottle 153 to move along the slide rail 152 and the sliding groove 154 all the time. An output pipe 155 is provided on the bottle body of the liquid adding bottle 153. A liquid adding hose 156 is provided in each dropper 151. The ends of the two liquid adding hoses 156 away from the droppers 151 are connected to the output pipe 155. At this time, a tee pipe can be used to connect the output pipe 155 and the two liquid adding hoses 156. The position where the output pipe 155 is connected to the liquid adding bottle 153 is lower than the liquid level height of the cleaning liquid in the liquid adding bottle 153.

[0032] Such as Figure 2 And Figure 3 , when it is necessary to drip cleaning liquid into the dropper 151, first move the liquid adding bottle 153 to a position lower than the outlet of the liquid adding hose 156 on the dropper 151. At this time, due to the influence of gravity, the liquid in the liquid adding bottle 153 cannot transport cleaning liquid into the liquid adding hose 156. When it is necessary to transport cleaning liquid into the liquid adding hose 156, the user pushes the liquid adding bottle 153 upward so that the position of the output pipe 155 on the liquid adding bottle 153 gradually becomes higher than the outlet position of the liquid adding hose 156. At this time, due to the influence of gravity, the cleaning liquid in the liquid adding bottle 153 will automatically flow into the liquid adding hose 156 and then into the dropper 151. At this time, the output pipe 155 can be arranged on the outer wall of the liquid adding bottle 153 close to the bottom.

[0033] As Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 , a fixing block 157 is provided on one side of the liquid adding bottle 153. The fixing block 157 is slidably connected to the slide rail 152 and the chute 154. At this time, a groove communicating with the chute 154 is provided on the slide rail 152 for the fixing block 157 to slide. A locking rod 158 is threadedly connected to the fixing block 157. One end of the locking rod 158 passes through the fixing block 157 and abuts against the slide rail 152 or the chute 154. At this time, in order to facilitate fixing the position of the liquid adding bottle 153 at will, the locking rod 158 can be tightened so that one end of the locking rod 158 abuts against the fixing block 157 or the bottom of the chute 154, thereby restricting the position of the fixing block 157 and fixing the position of the liquid adding bottle 153. In order to further fix the position of the liquid adding bottle 153, embedding grooves for one end of the locking rod 158 to be embedded can be provided at the bottom of the fixing block 157 and the chute 154. At this time, the position of the locking rod 158 is made more stable.

[0034] As Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 , a connecting block 159 threadedly connected to the upper end pipe orifice of the dropper 151 is provided at one end of the liquid adding hose 156 inside the dropper 151. The outlet of the liquid adding hose 156 extends out of the lower end of the connecting block 159. At this time, it is convenient to fix one end of the liquid adding hose 156 at the upper end pipe orifice of the dropper 151.

[0035] As Figure 4 As shown in Figure 4 , a driving member for driving the rotating rod 15 to rotate so that the horizontal end turns away from the substrate 12 and turns to directly above the substrate 12 is provided on the base 1.

[0036] As Figure 4The driving member includes a positioning column 16 arranged at the upper end of the base 1. The cross section of the positioning column 16 is semicircular. The positioning column 16 is rotatably connected to a sleeve 161. A horizontal plate 162 is arranged on one side of the outer wall of the sleeve 161. The rotating rod 15 is arranged on the upper end of the horizontal plate 162. A right-angled triangle block 163 is arranged on the inner wall of the sleeve 161. After the two right-angled sides of the triangle block 163 are removed, the other side is an arc surface that contacts the inner wall of the sleeve 161. When the sleeve 161 is rotated to When the rotating rod 15 on the horizontal plate 162 rotates to the top of the substrate 12, one right-angled side of the triangular block 163 contacts the straight side of the positioning column 16. When the sleeve 161 is rotated to make the rotating rod 15 on the horizontal plate 162 rotate away from the top of the substrate 12, the other right-angled side of the triangular block 163 contacts the straight side of the positioning column 16. At this time, the rotating drum is rotated to drive the rotating rod 15 on the horizontal plate 162 to rotate together, thereby facilitating the change of the position of the dropper 151. When the sleeve 161 does not need to be rotated, a positioning rod 164 is penetrated on the horizontal plate 162. The upper end of the positioning rod 164 passes through the horizontal plate 162 and a contact block 165 that contacts the upper end surface of the horizontal plate 162 is provided at the end that passes through. A plurality of insertion holes 166 are provided on the upper end surface of the base 1 for the lower end of the positioning rod 164 to pass through. At this time, the positioning rod 164 is inserted into the corresponding insertion hole 166, which can limit the rotation of the cross plate 162, and then limit the rotation of the sleeve 161. When one end of the positioning rod 164 enters the insertion hole 166, the abutment block 165 abuts against the upper end surface of the cross plate 162. There are at least two insertion holes 166, and one is located when the rotating rod 15 rotates to the top of the substrate 12, and the other is located when the rotating rod 15 rotates away from the top of the substrate 12.

[0037] like Figure 5, or, the driving member includes a placement groove 17 formed in the base 1. One end of the vertical end of the rotating rod 15 penetrates into the placement groove 17. An L-shaped swing rod 18 is provided at one end of the rotating rod 15 located in the placement groove 17. The two sides of the swing rod 18 form a 90° angle. Placement blocks 181 are provided on the upper groove wall of the placement groove 17 at both ends of the swing rod 18. And a pull rod 182 is slidably connected to each of the two placement blocks 181. One ends of the two pull rods 182 are respectively slidably connected to the two sides of the swing rod 18. The two pull rods 182 are perpendicularly distributed. A cylinder 183 for driving one of the pull rods 182 to move within the placement block 181 is provided on the upper groove wall of the placement groove 17. At this time, when the cylinder 183 drives one of the pull rods 182 to move away from the other pull rod 182 within the placement block 181, this pull rod 182 drives one side of the swing rod 18 to move as well, causing the corner point of the swing rod 18 to rotate, thereby driving the rotating rod 15 to rotate. At this time, one end of the other pull rod 182 gradually pulls away from the placement block 181. When the cylinder 183 drives this pull rod 182 to move in the reverse direction, this pull rod 182 drives one side of the swing rod 18 to move towards the other pull rod 182, causing the corner point of the swing rod 18 to rotate in the opposite direction, facilitating the reset of the rotating rod 15. At this time, the end of the other pull rod 182 connected to the swing rod 18 gradually moves towards the placement block 181, and the operation is convenient.

[0038] Such as Figure 5 , sliding cylinders 184 are slidably connected to both sides of the swing rod 18. One end of the pull rod 182 away from the placement block 181 is rotatably connected to one end of the sliding cylinder 184 facing the upper groove wall of the placement groove 17. At this time, the setting of the sliding cylinder 184 facilitates the sliding of one end of the pull rod 182 along the respective two sides of the swing rod 18.

[0039] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
