DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0031] A rotating assembly 5 is installed inside the positioning block 3, and the rotating assembly 5 includes a rotating rod 51 rotatably connected to the inside of the positioning block 3, a worm 52 is fixedly sleeved on the outer side of the rotating rod 51, and a worm wheel 53 rotatably connected to the positioning block 3 is meshed on the outer side of the worm 52. A connecting ring 54 is welded to the top of the worm wheel 53, and the top of the connecting ring 54 is fixedly connected to the bottom end of the transmission assembly mounting plate 4. A disc 55 is fixedly installed at one end of the rotating rod 51 and fits into an end surface position of the positioning block 3. Two round sticks 510 are slidably connected to the outer side of the disc 55. A sealing cover 56 is welded to one end of the positioning block 3 at the outer side of the disc 55, and a sound amplification cover 514 is installed inside the sealing cover 56.

[0032] like Figure 3 and Figure 4 As shown, a mounting frame 59 is rotatably mounted on the outer side of the round stick 510, and two spring rods 58 are symmetrically embedded and mounted on one end surface of the mounting frame 59. A support bar 57 is embedded and mounted on one end surface of the two spring rods 58, and the support bar 57 is fixedly mounted inside the sealing cover 56. Four positioning grooves are opened on the outer side of the disc 55, and the round stick 510 is located inside the positioning grooves;

[0033] As the mounting frame 59 is driven to move under the action of the tension of the spring rod 58, the mounting frame 59 drives the round stick 510 to enter the positioning groove of the disc 55 when moving, so that the round stick 510 limits the disc 55, thereby increasing the difficulty of rotating the disc 55.

[0034] like Figure 3 and Figure 4As shown, the inner wall of the sealing cover 56 is fitted with an arc strip 511, one end of the arc strip 511 is welded with a slider 512, and the slider 512 slides in a circle around the center point of the sealing cover 56, a connecting pipe 513 is embedded and installed inside the slider 512, one end of the connecting pipe 513 is located inside the sealing cover 56, and the other end of the connecting pipe 513 is fixedly connected to the sound amplification cover 514, and a slide groove is provided inside the sealing cover 56 at a position corresponding to the outer side of the slider 512, which is used for the displacement of the slider 512 and limits the slider 512, and the shape of the slider 512 is an I-shaped shape, and the size of the arc strip 511 is larger than the size of the slide groove, which can block the slide groove to prevent the sound from scattering along the slide groove;

[0035] When the slider 512 moves, the arc bar 511 is driven to move. When the slider 512 and the arc bar 511 move, the angle of the connecting pipe 513 is driven to change. At this time, the angle of the sound amplifying cover 514 is driven to change, so that the sound amplifying cover 514 is opposite to the staff, so that the staff can receive the sound generated by the collision between the round stick 510 and the disc 55, and then warn the staff through sound.

[0036] like Figure 2 and Figure 5 As shown, a screening assembly 13 is installed inside the oil receiving box 12, and the screening assembly 13 includes two mounting bars 1301 symmetrically fixedly installed on the inner wall of the oil receiving box 12, a magnetic gauze 1303 is fixedly installed between the two mounting bars 1301, a gauze 1304 is arranged on the top of the magnetic gauze 1303, and a rotating rod 1302 is movably installed between the two mounting bars 1301;

[0037] When the drive motor is disassembled, the internal lubricating oil needs to be discharged into the oil collecting box 12. At this time, the lubricating oil flows along the surface of the gauze 1304 at the top of the magnetic mesh 1303. At the same time, the magnetic mesh 1303 adsorbs the magnetic material inside the lubricating oil, and the lubricating oil falls downward along the inside of the gauze 1304. At the same time, the material that cannot be adsorbed after the drive motor shell is worn out falls into the oil collecting box 12, thereby separating the magnetic material from the lubricating oil and the material that cannot be adsorbed, thereby facilitating the observation of the damage condition of the magnetic objects inside the drive motor.

[0038] like Figure 5 and Figure 6 As shown, a slide bar 1305 is connected to the rotating rod 1302 for forward and backward sliding movement, a strong magnet 1306 is fixedly installed at the bottom of the slide bar 1305, the inclination angle between the magnet mesh 1303 and the ground is thirty degrees or one hundred and fifty degrees, and the height between one end of the magnet mesh 1303 close to the positioning block 3 and the ground is greater than the height between the other end and the ground;

[0039] It can facilitate the material to flow along the surface of the magnet mesh 1303, and under the action of the strong magnet 1306, the magnetic material on the surface of the magnet mesh 1303 is adsorbed. At the same time, under the action of the sliding bar 1305, the strong magnet 1306 is driven to move, so that the strong magnet 1306 adsorbs the magnetic material adsorbed on the surface of the magnet mesh 1303, which is convenient for personnel to observe and reduces the difficulty of observing the magnetic material.

[0040] like Figure 6 and Figure 7 As shown, a round rod 1307 is fixedly installed on one end face of the rotating rod 1302, a rectangular block 1308 is movably connected inside the round rod 1307 and the rotating rod 1302, and one end of the rectangular block 1308 is fixedly connected to one end face of the sliding bar 1305, and a positioning ring 1309 is fixedly sleeved on the outer side of the round rod 1307 at the front position of the oil receiving box 12, and a limiting ring 1311 is fixedly installed on the front face of the oil receiving box 12, and the center point of the limiting ring 1311 and the center point of the positioning ring 1309 are on the same horizontal line, and the inner wall of the limiting ring 1311 is equidistantly fixed. A spring column 1312 is installed, and a friction plate 1313 is clamped and installed at the movable end of the spring column 1312, and the friction plate 1313 is fitted with the inner wall of the positioning ring 1309, and a plastic strip 1310 is integrally formed equidistantly on the outer side of the positioning ring 1309, and a placement groove is opened at the outer edge of the positioning ring 1309 corresponding to one end of the plastic strip 1310, and the plastic strip 1310 is located inside the placement groove and is used for connecting the plastic strip 1310 and the positioning ring 1309, thereby reducing the difficulty of connecting the plastic strip 1310 and the positioning ring 1309;

[0041] When the rectangular block 1308 rotates, the round rod 1307 is driven to rotate, and when the round rod 1307 rotates, the rotating rod 1302 is driven to rotate, and when the rotating rod 1302 rotates, the strong magnet 1306 is driven to deflect, and in the process, the positioning ring 1309 is driven to rotate, and when the positioning ring 1309 rotates, the plastic strip 1310 is driven to deflect, and after the plastic strip 1310 is deflected, it is separated from the placement groove of the limit ring 1311, and then the friction plate 1313 is driven to fit the outer side of the positioning ring 1309 under the tension of the spring column 1312, so that the positioning ring 1309 is fixed by friction and compression, and when the positioning ring 1309 is fixed, the rotating rod 1302 is driven to be fixed, so as to prevent the rotating rod 1302 from self-rotating due to displacement after the angle deflection, so as to facilitate personnel to observe the outer side of the strong magnet 1306, and reduce the difficulty of observing the strong magnet 1306.

[0042] Working principle: During the actual use of the device, the user installs the transmission assembly and the drive motor assembly on the transmission assembly mounting plate 4 and the drive motor assembly mounting plate 9 respectively. At this time, the user pushes the rear end fixing block 10 of the drive motor so that the rear end fixing block 10 of the drive motor enters the bottom end of the drive motor assembly, and then rotates the extrusion screw 11 to fix the rear end fixing block 10 of the drive motor, and then combines the transmission assembly and the drive motor assembly, and then pours lubricating oil into the drive motor assembly, so that the power motor drive motor is installed on the surface of the workbench 2;

[0043] When disassembly is required, the transmission assembly and the drive motor assembly are disassembled, and the lubricating oil inside the drive motor assembly is dumped before that. At this time, the lubricating oil inside the drive motor assembly falls into the oil collecting box 12, and then the lubricating oil flows along the surface of the gauze 1304 at the top of the magnetic gauze 1303. At the same time, the magnetic substance inside the lubricating oil is adsorbed on the magnetic gauze 1303, and the lubricating oil falls downward along the gauze 1304 and the inside of the magnetic gauze 1303. At the same time, the magnetic gauze 1303 that cannot be adsorbed after the drive motor housing is worn falls into the oil collecting box 12, and the gauze 1304 on the top of the magnetic gauze 1303 is used to further filter and adsorb the magnetic substance in the oil to help purify the oil. At the same time, non-magnetic impurities cannot be adsorbed by the magnetic gauze 1303 and fall along the inclined magnetic gauze 1303, thereby ensuring the purity of the oil. The lubricating oil treated as above is purer and can reduce impurity pollution.

[0044] Then the personnel operates the driving structure 7, which drives the moving block 8 to move inside the guide rail 6, thereby driving the driving motor assembly to the rightmost end;

[0045] Then, the rectangular block 1308 is pulled, and when the rectangular block 1308 moves, the slide bar 1305 is driven to move inside the rotating rod 1302, thereby driving the strong magnet 1306 to move. At this time, the strong magnet 1306 makes the surface of the magnet mesh 1303 adsorb the magnetic material on the top of the gauze 1304, so that the magnetic material is transferred to one end surface of the strong magnet 1306, and then the rectangular block 1308 is rotated. When the rectangular block 1308 rotates, the round rod 1307 is driven to rotate, and when the round rod 1307 rotates, the rotating rod 1302 is driven to rotate. When the rotating rod 1302 rotates, the strong magnet 1306 is driven to deflect, and the deflected strong magnet 1306 enters the top of the workbench 2. By observing the iron filings, it is easy to observe the mechanical wear inside the drive motor, so that the wear of the drive motor or other related mechanical parts can be discovered early, so as to carry out timely repair or replacement to avoid the expansion of the fault, and more accurately judge the specific time when the equipment needs to be maintained, so as to adjust the maintenance plan of the equipment, avoid unnecessary downtime, and effectively extend the service life of important equipment such as the drive motor;

[0046] In the process, the positioning ring 1309 is driven to rotate, and the rotation of the positioning ring 1309 drives the plastic strip 1310 to deflect. After the plastic strip 1310 is deflected, it is separated from the placement groove of the limit ring 1311, and then the plastic strip 1310 is clamped in the placement groove again, so that the positioning ring 1309 is initially fixed after rotation. At the same time, the friction plate 1313 and the outer side of the positioning ring 1309 are driven to fit under the tension of the spring column 1312, so that the positioning ring 1309 is fixed by friction and compression. Through multiple fixations, the deflected rotating rod 1302 is fixed for the second time, so as to prevent the rotating rod 1302 from rotating, so that the rotating rod 1302 is fixed more stably, and it is further convenient for personnel to observe the outer side of the strong magnet 1306.

[0047] Finally, the personnel rotate the rotating rod 51, and the rotating rod 51 drives the worm 52 to rotate, and the worm 52 drives the worm wheel 53 and the disc 55 to rotate synchronously. At this time, the worm wheel 53 drives the connecting ring 54 to rotate, and the connecting ring 54 drives the transmission assembly mounting plate 4 to rotate, so that the transmission assembly mounting plate 4 can rotate 360 ​​degrees, so as to facilitate the all-round observation of the transmission assembly at the top of the transmission assembly mounting plate 4, so that the transmission assembly can be observed more clearly;

[0048] Since four positioning grooves are provided on the outer side of the disc 55, the mounting frame 59 is driven to move under the action of the tension of the spring rod 58. When the mounting frame 59 moves, it drives the mounting frame 59 to move. When the mounting frame 59 moves, it drives the round stick 510 to enter the positioning groove of the disc 55, so that the round stick 510 limits the disc 55, thereby increasing the difficulty of rotating the disc 55. By increasing the difficulty of rotating the disc 55, the friction of the transmission assembly mounting plate 4 is increased when rotating 90 degrees, 180 degrees, 270 degrees and 360 degrees, so that the end face of the transmission assembly mounting plate 4 and the end face of the positioning block 3 are overlapped, which further facilitates the transmission assembly mounting plate 4

[0049] The mounting plate 9 of the drive motor assembly is connected to the mounting plate 4 of the transmission assembly, so as to facilitate the assembly between the transmission assembly and the drive motor. This method helps to improve the assembly accuracy and efficiency between the mounting plate 4 of the transmission assembly and the mounting plate 9 of the drive motor assembly, and completes the assembly work more conveniently and efficiently, reduces the time and manpower waste caused by assembly difficulties, reduces slight operating errors during the installation process, and is not likely to cause assembly failure or subsequent problems, thereby improving the reliability of the assembly process;

[0050] Then the personnel adjusts the slider 512. When the slider 512 moves, the arc strip 511 moves. When the slider 512 and the arc strip 511 move, the angle of the connecting pipe 513 changes. At this time, the angle of the sound amplifier 514 changes, so that the sound amplifier 514 is opposite to the personnel. When the round stick 510 quickly enters the positioning groove of the disc 55, a collision occurs between the round stick 510 and the disc 55. The sound generated by the collision enters the inside of the sound amplifier 514 along the connecting pipe 513, and enters the ears of the installer along the sound amplifier 514. Through the sound feedback, even if the operator's attention is distracted or the operation speed is slow, the confirmation signal of the transmission assembly mounting plate 4 when rotating can be obtained immediately, thereby improving the accuracy of the transmission assembly mounting plate 4 when rotating by ninety degrees. In addition, due to the existence of the sound feedback mechanism, it is easier to standardize and regulate the ninety-degree rotation of the transmission assembly mounting plate 4, reducing the assembly difficulties caused by the non-standard ninety-degree process of the transmission assembly mounting plate 4, and improving the efficiency and effect of the assembly process.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
