Description

Technical Field

[0001] The invention relates to the technical field of ferrography, and in particular to an intelligent double-rotating ferrography device for oil detection of mining equipment. Background Art

[0002] Ferrograph is a new mechanical wear test method invented in the 1970s. It uses magnetic force to separate metal particles from oil and arrange them on a substrate according to the size of the particles. It can not only read the relative concentration of large and small particles, but also make further analysis of the physical properties of the particles. The analysis procedure of ferrograph generally includes four basic steps: sampling, spectrum preparation, observation and analysis, and conclusion.

[0003] The Chinese patent with the announcement number CN205679504U discloses a ferroscope, including 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 first stepping motor. Several substrate makers are evenly distributed on the ring. The annular waste liquid collection tank is installed on the base and is located at the lower side of the lowest point of the substrate rack. An oil sample tray and a cleaning liquid tray are movably installed on the bracket. The raised portion of the oil sample tray and the raised portion of the cleaning liquid tray are staggered. The raised portion of the oil sample tray corresponds to the position of the substrate maker on the ring, which solves the problem of low efficiency of making ferroscope sheets by existing ferroscopes. The present application provides another solution. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] An intelligent dual-rotating iron spectrometer device for oil detection in mining equipment, such as Figure 1 and Figure 2 , including a base 1 and two cylinders 11 rotatably connected to the upper end of the base 1, one end of the two cylinders 11 passes through the upper end of the base 1 and is provided with a magnetic head 12, a substrate 121 is placed on the upper end of the magnetic head 12, a driving groove 122 is provided in the base 1, the lower ends of the two cylinders 11 enter the driving groove 122, and a driving member for driving the two cylinders 11 to rotate is provided in the driving groove 122. When working, first drop a few drops of anhydrous ethanol on the magnetic head 12, and then place a glass substrate 121 on it. Note: No bubbles should be generated between the glass substrate 121 and the magnetic head 12, and the substrate 121 is soaked in anhydrous ethanol and "fixed" at the end of the magnetic head 12, or there is a substrate 121 frame at the end of the magnetic head 12 to fix the substrate 121.

[0030] like Figure 1 and Figure 2 The arrangement of the two cylinders 11 enables the magnetic heads 12 to have two, which facilitates the driving part to rotate the two substrates 121 at the same time. At this time, the efficiency of making the iron spectrum sheet is higher than that of the conventional one substrate 121. When in use, the oil sample to be tested can be manually sucked into the oil sample syringe, and the oil sample can be dripped onto the corresponding substrate 121. The driving part drives the cylinder 11 to rotate to make the substrate 121. Then, the cleaning liquid syringe is manually filled with cleaning liquid, and the cleaning liquid in the cleaning liquid syringe is released for cleaning, and the production of two substrates 121 is completed at one time.

[0031] like Figure 2 and Figure 3The driving member includes a first motor 123 disposed at the bottom of the driving groove 122, a first driving wheel 124 is coaxially connected to the output shaft of the first motor 123, and driven wheels 125 are coaxially disposed at the lower ends of the two cylinders 11. The first driving wheel 124 and the two driven wheels 125 are distributed along three points of a triangle, and the first driving wheel 124 and the two driven wheels 125 are connected by a belt 126. At this time, the belt 126 is provided with teeth that mesh with the teeth on the first driving wheel 124 and the two driven wheels 125, so that the first motor 123 can drive the two cylinders 11 to rotate through the belt 126.

[0032] like Figure 4 Alternatively, the driving member includes an annular placement groove 13 provided at the lower end of the cylinder 11, and a driving wheel 131 is sleeved on the outer wall of the cylinder 11 through the placement groove 13. When the driving wheel 131 is sleeved into the groove wall of the placement groove 13, a limiter is provided at the lower end of the cylinder 11 to limit the movement of the driving wheel 131. A second motor 132 is provided at the bottom of the driving groove 122 between the two cylinders 11, and a second driving wheel 133 is coaxially connected to the output shaft of the second motor 132, and the two ends of the second driving wheel 133 are respectively meshed with the two driving wheels 131. At this time, the second motor 132 drives the two driving wheels 131 to rotate through the second driving wheel 133, thereby facilitating the rotation of the two cylinders 11. At this time, the setting of the limiter facilitates the installation of the driving wheel 131 at the lower end of the cylinder 11.

[0033] like Figure 4 The limiting member includes a moving block 14 disposed at the lower end of the cylinder 11, and a threaded rod 141 is disposed at the upper end of the moving block 14, which enters the lower end surface of the cylinder 11 and is threadedly connected to the cylinder 11. The threaded rod 141 is rotated so that the moving block 14 presses the driving wheel 131 against the bottom of the placement groove 13, so that the driving wheel 131 rotates and drives the cylinder 11 to rotate.

[0034] like Figure 4 The upper end of the moving block 14 is provided with a contact cylinder 142 which is sleeved on the outer wall of the placement groove 13. The upper end of the contact cylinder 142 contacts the wheel surface of the driving wheel 131. When the contact cylinder 142 contacts the wheel surface of the driving wheel 131, there is a gap between the upper end surface of the moving block 14 and the lower end surface of the cylinder 11. At this time, the moving block 14 is rotated so that the upper end of the contact cylinder 142 contacts one side of the driving wheel 131 on the bottom of the placement groove 13. At this time, when the driving wheel 131 rotates, it is convenient to drive the cylinder 11 to rotate together. When the contact cylinder 142 contacts the wheel surface of the driving wheel 131, there is a gap between the upper end surface of the moving block 14 and the lower end surface of the cylinder 11. The purpose of this design is to facilitate the contact cylinder 142 to press the driving wheel 131.

[0035] like Figure 5 and Figure 6Alternatively, the limiting member includes a clamping block 143 fixedly arranged on the wall of the placement groove 13 at the lower end of the cylinder 11 and located below the driving wheel 131. In this case, after the driving wheel 131 is inserted into the placement groove 13, the clamping block 143 is welded to the outer wall of the cylinder 11, that is, the clamping block 143 is also on the wall of the placement groove 13, so that the driving wheel 131 rotates in the space between the clamping block 143 and the bottom of the placement groove 13. At this time, the driving wheel 131 is supported by the clamping block 143, that is, when the driving wheel 131 rotates, it will not drive the cylinder 11 to rotate together. The cylinder 11 is provided with a clamping member that drives the cylinder 11 to rotate together with the driving wheel 131 when it rotates. The clamping member drives the cylinder 11 to rotate as the driving wheel 131 rotates as needed. When the cylinder 11 does not need to rotate, the clamping member releases the restriction on the cylinder 11, so that the two cylinders 11 can be used separately.

[0036] like Figure 5 and Figure 6 The clamping member includes a clamping groove 15 which is opened on the lower end surface of the cylinder 11 and distributed along the length direction of the cylinder 11. The clamping groove 15 is a cylindrical groove and is coaxial with the cylinder 11. A slider 151 is slidably connected in the clamping groove 15. The slider 151 is also a cylinder, so that when the cylinder 11 rotates, the slider 151 does not rotate with the cylinder 11. A cylinder 152 for driving the slider 151 to move up and down in the clamping groove 15 is provided at the bottom of the driving groove 122. The piston rod of the cylinder 152 is rotatably connected to the slider 151. A first groove 153 is opened on the inner ring wall of the driving wheel 131. A second groove 154 opposite to the first groove 153 is opened on the groove wall of the placement groove 13. The second groove 154 is connected to the clamping groove 15 and the slider 151 is moved toward the second groove 154. A connecting groove 155 is opened on the side, and a connecting block 156 is slidably connected in the connecting groove 155. A compression spring 157 is provided at the bottom of the connecting groove 155 so that one end of the connecting block 156 extends out of the notch of the connecting groove 155. Both ends of the connecting block 156 along the length direction of the card slot 15 are provided with inclined surfaces 158. The setting of the inclined surface 158 makes the width of the end of the connecting block 156 away from the connecting groove 155 smaller than the width of the end of the connecting block 156 close to the connecting groove 155. When the compression spring 157 is in the original state, one end of the connecting block 156 extends out of the notch of the connecting groove 155 and enters the first groove 153 through the second groove 154. At this time, one end of the inclined surface 158 enters the first groove 153, and the other end is located in the connecting groove 155.

[0037] like Figure 5 and Figure 6When it is necessary to make the cylinder 11 rotate with the driving wheel 131, the cylinder 152 drives the slider 151 to move upward in the slot 15, so that the connecting slot 155 and the first slot 153 and the second slot 154 are located in the same plane. At this time, one end of the connecting block 156 enters the second slot 154 and contacts the inner wall of the driving wheel 131 until the first slot 153 on the driving wheel 131 rotates to a position opposite to the second slot 154. At this time, the connecting block 156 is elastically compressed under the compression of the spring 157. Under the action of the restoring force, the cylinder 151 enters the first groove 153, so that the cylinder 11 is driven to rotate together with the driving wheel 131 when it is necessary to release the limit between the cylinder 11 and the driving wheel 131, the cylinder 152 drives the slider 151 to move downward, so that the inclined surface 158 is resisted by the groove wall of the second groove 154, and then the connecting block 156 gradually enters the connecting groove 155 until the connecting block 156 slides out of the first groove 153. At this time, the driving wheel 131 will not drive the cylinder 11 to rotate when it rotates.

[0038] like Figure 5 and Figure 6 , a positioning plate 16 is provided on the telescopic rod of the cylinder 152. When the connecting groove 155, the first groove 153 and the second groove 154 are located in the same plane, the upper end of the positioning plate 16 contacts the lower end surface of the cylinder 11, and a first pressure sensor 161 for controlling the cylinder 152 to stop working is embedded in the upper end surface of the positioning plate 16. At this time, the cylinder 152 drives the slider 151 to move upward, so that the positioning plate 16 gradually moves closer to the cylinder 11. When the first pressure sensor 161 on the positioning plate 16 is subjected to the resistance force of the lower end of the cylinder 11, the first pressure sensor 161 controls the cylinder 152 to stop working. At this time, the connecting groove 155, the first groove 153 and the second groove 154 are located in the same plane. In addition, the cylinder 152 can be started by installing a button on the base 1 to control the cylinder 152 to start working. This is a prior art and will not be described in detail here. When the button is pressed for the first time, the cylinder 152 drives the slider 151 to move upward. When the button is pressed for the second time, the cylinder 152 drives the slider 151 to move downward.

[0039] like Figure 1 and Figure 7 The upper end surface of the base 1 is provided with an oil collecting cylinder 17 on the outer sleeve of each cylinder 11. The setting of the oil collecting cylinder 17 facilitates the collection of residual oil after being thrown out along the substrate 121. The inner wall of the upper end of each oil collecting cylinder 17 is provided with a circular guide plate 171 that extends downwardly and obliquely toward the cylinder 11. The setting of the guide plate 171 facilitates the residual oil to enter the oil collecting cylinder 17. In addition, there is a gap between the end of the guide plate 171 away from the inner wall of the upper end of the oil collecting cylinder 17 and the inner wall of the end of the oil collecting cylinder 17 close to the cylinder 11. The setting of the guide plate 171 reduces the size of the upper end opening of the oil collecting cylinder 17, thereby reducing the emission of odor after the residual oil accumulates in the oil collecting cylinder 17.

[0040] Obviously, those skilled in the art can make various changes and modifications 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 equivalents, the present invention is also intended to include these modifications and variations.
