Equipment lubrication management is an important means to ensure the normal operation of the equipment, reduce the wear of equipment parts, improve production efficiency, improve equipment utilization efficiency, reduce equipment failure rate and reduce equipment maintenance costs. However, during the actual equipment operation process, the operator cannot monitor the changes in the differential box lubrication level in real time. Therefore, the existing differential box liquid level alarm device of the draw frame has been continuously innovated and developed. Therefore, it can be seen that the current differential box liquid level alarm device of the draw frame still has some problems.

[0003] When the existing draw frame differential case liquid level alarm device is in use, due to different use environments, the staff needs to monitor the changes in the differential case lubrication liquid level according to the actual use environment. However, when the existing draw frame differential case liquid level alarm device is in use, it is difficult for the staff to adjust the draw frame differential case liquid level alarm device according to the actual use environment, which is inconvenient for the staff to use. Therefore, a draw frame differential case liquid level alarm device is urgently needed to solve the above problem. Utility Model Content

[0023] See also Figure 1-5 , an embodiment provided by the utility model:

[0024] A liquid level alarm device for a drawing frame differential case includes a support plate 1, an alarm 2 is fixedly connected to the top of the support plate 1, a PLC controller 3 is fixedly connected to the outer wall of the alarm 2, a first guide frame 7 is fixedly connected to the bottom of the support plate 1, a float 8 is slidably connected to the inner side of the first guide frame 7, a counterweight 9 is fixedly connected to the bottom of the float 8, a second guide frame 11 is slidably connected to the bottom of the first guide frame 7, a mounting plate 14 is slidably connected to the inner side of the second guide frame 11, a trigger mechanism is provided at the bottom of the mounting plate 14, and the trigger mechanism is electrically connected to the PLC controller 3.

[0025] When the liquid level alarm device for the drawing frame differential case is in use, the support plate 1 can provide an installation position for the alarm 2, and the first guide frame 7 and the second guide frame 11 can guide the float 8. When the lubricating fluid inside the drawing frame differential case is consumed, the float 8 will drop along with the liquid level of the lubricating fluid. When the counterweight block 9 at the bottom of the float 8 contacts the trigger mechanism, the trigger mechanism is triggered, and the trigger mechanism sends an electrical signal to the PLC controller 3, which can enable the PLC controller 3 to control the alarm 2 to sound an alarm to remind the staff.

[0026] Furthermore, a connecting plate 4 is fixedly connected to the outer wall of one side of the support plate 1, and a fixing plate 6 is slidably connected to the inner side of the top end of the connecting plate 4. A first fixing bolt 5 is installed through a thread on the outer wall of the top end of the connecting plate 4, and the bottom end of the first fixing bolt 5 rests on the bottom outer wall of the fixing plate 6.

[0027] When the liquid level alarm device of the differential case of the drawing frame is in use, the fixing plate 6 is fixed in the installation position and the liquid level alarm device of the differential case of the drawing frame is placed inside the differential case of the drawing frame, so that the liquid level alarm device of the differential case of the drawing frame can be used normally. The fixing plate 6 slides on the inner side of the top end of the connecting plate 4, so that the position of the liquid level alarm device of the differential case can be adjusted. After the adjustment, the bottom end of the first fixing bolt 5 is rotated so that the bottom end of the first fixing bolt 5 is against the outer wall of the bottom end of the fixing plate 6, thereby ensuring the stability of the fixing plate 6.

[0028] Furthermore, a fastening bolt 10 is threadedly installed through the outer wall of the bottom end of the first guide frame 7 , a telescopic plate 12 is fixedly connected to the top end of the second guide frame 11 , and the telescopic plate 12 is slidably connected to the inner side of the bottom end of the first guide frame 7 .

[0029] By sliding the telescopic plate 12 on the inner side of the bottom end of the first guide frame 7, the height between the first guide frame 7 and the second guide frame 11 can be adjusted, so that the staff can adjust it according to the depth of the differential box of the drawing frame, which is convenient for the staff to install and use.

[0030] Furthermore, a sliding groove 13 is opened on the outer wall of the second guide frame 11, and a slide plate 15 is fixedly connected to the outer walls on both sides of the mounting plate 14, and the slide plate 15 passes through the sliding groove 13 and is located on the outer wall of the second guide frame 11. The outer wall of the slide plate 15 is threaded with a second fixing bolt 16, and the second fixing bolt 16 is against the outer wall of the second guide frame 11.

[0031] By sliding the slide plate 15 on the inner side of the slide groove 13, the position of the mounting plate 14 can be adjusted, so that the mounting plate 14 drives the trigger mechanism to be adjusted. After the adjustment, the second fixing bolt 16 is rotated so that the second fixing bolt 16 abuts against the outer wall of the second guide frame 11, thereby ensuring the stability of the mounting plate 14. By adjusting the trigger mechanism, the staff can adjust the limit of the liquid level alarm according to the actual use environment.

[0032] Furthermore, the trigger mechanism includes a protective cover 17, a gravity sensor 18 is fixedly connected to the inside of the protective cover 17, a pressure detection port 20 is fixedly connected to the top of the mounting plate 14, and the pressure detection port 20 is electrically connected to the gravity sensor 18, a lubricating fluid concentration sensor 19 is fixedly connected to the inside of the protective cover 17, and the detection end of the lubricating fluid concentration sensor 19 passes through the outer wall of the protective cover 17.

[0033] When the liquid level alarm device for the draw frame differential case is in use, the gravity sensor 18 and the lubricant concentration sensor 19 can be protected by the protective cover 17. The concentration of the lubricant inside the draw frame differential case can be detected by the lubricant concentration sensor 19. When the lubricant concentration is too low, the alarm 2 can be controlled by the PLC controller 3 to sound an alarm to remind the staff. When the lubricant inside the draw frame differential case is consumed, the float 8 will drop with the liquid level of the lubricant. When the counterweight block 9 at the bottom of the float 8 contacts the pressure detection port 20, the gravity sensor 18 receives the gravity induction, thereby sending an electrical signal to the PLC controller 3, so that the PLC controller 3 controls the alarm 2 to sound an alarm to remind the staff.

[0034] Working principle: When the liquid level alarm device of the draw frame differential case is used, the fixing plate 6 is fixed in the installation position, and the liquid level alarm device of the draw frame differential case is placed inside the draw frame differential case, so that the liquid level alarm device of the draw frame differential case can be used normally. The concentration of the lubricating fluid inside the draw frame differential case can be detected by the lubricating fluid concentration sensor 19. When the concentration of the lubricating fluid is too low, the alarm 2 can be controlled by the PLC controller 3 to sound an alarm to remind the staff. When the lubricating fluid inside the draw frame differential case is consumed, the float 8 will follow the liquid level of the lubricating fluid to drop. When the counterweight block 9 at the bottom of the float 8 contacts the pressure detection port 20, the gravity sensor 18 receives the gravity induction, thereby sending an electrical signal to the PLC controller 3, so that the PLC controller 3 controls the alarm 2 to sound an alarm to remind the staff.

Any reference sign in a claim should not be construed as limiting the claim to which it relates.
