Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder monitoring technology, specifically to an integrated real-time monitoring hydraulic cylinder. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines. The output force of a hydraulic cylinder is directly proportional to the effective area of ​​the piston and the pressure difference between its two sides. A hydraulic cylinder basically consists of a cylinder barrel and cylinder head, a piston and piston rod, a sealing device, a buffer device, and an exhaust device. The buffer device and exhaust device are determined according to the specific application, while the other devices are indispensable.

[0003] For example, patent document CN 220769846 U discloses a hydraulic cylinder with displacement monitoring, including a cylinder body, a cylinder bottom, a cylinder head, and a plunger. Both the plunger and the cylinder bottom have cavities. The cylinder bottom has a guide tube, which is fixedly connected to the cylinder bottom and embedded in the cavities of the cylinder bottom and the plunger. A displacement sensor is fixedly connected to the cylinder bottom. A connecting pipe is slidably connected to the guide tube, and a connecting plate is fixedly connected to the connecting pipe. One end of the connecting plate is fixedly connected to the displacement sensor, and the other end is connected to the plunger via a connecting strip. During operation, when the plunger rises, it drives the connecting strip and the connecting plate fixed to the connecting strip to rise. The connecting plate then drives the probe of the displacement sensor to rise, thereby achieving displacement monitoring of the plunger. Simultaneously, the guide tube, in conjunction with the connecting pipe, connecting plate, and cylinder bottom, achieves sealing of the displacement sensor, solving the sealing problem of the displacement sensor in the hydraulic cylinder.

[0004] However, in actual use, due to its structural limitations, this structure can only be directly installed on a simple hydraulic cylinder. The real-time monitoring sensor cannot make sufficient contact with the hydraulic cylinder, which can easily lead to monitoring errors. At the same time, the device cannot efficiently monitor abnormal leakage of the hydraulic cylinder, which cannot meet the needs of daily use. Therefore, it is urgent to design an integrated real-time monitoring hydraulic cylinder to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated real-time monitoring hydraulic cylinder to solve the problems mentioned in the background art. In actual use, due to the limitations of its own structure, the existing structure can only be used for simple direct installation of the hydraulic cylinder. The real-time monitoring sensor cannot make sufficient contact with the hydraulic cylinder, which easily leads to monitoring deviation. At the same time, the device cannot perform efficient monitoring of abnormal leakage of the hydraulic cylinder, and cannot meet the needs of daily use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated real-time monitoring hydraulic cylinder, including a mounting bracket, mounting side frames fixedly connected to the four sides of the mounting bracket, a monitoring component movably connected to the top of the mounting bracket, and a mounting component provided at the bottom of the mounting bracket; The monitoring component includes a mounting cover, the top of which is movably connected to the mounting bracket. A shrink ring seat is provided inside the mounting cover, and an air control pump is provided on the back of the shrink ring seat. The mounting assembly includes a limiting connector, the bottom end of the mounting bracket is fixedly connected to the limiting connector, the bottom end of the limiting connector is fixedly connected to a liquid polymer cover, and the bottom end of the liquid polymer cover is fixedly connected to a mounting plate.

[0007] Preferably, the inner wall of the liquid-collecting bottom cover is provided with a conical inner liner, and a liquid measuring probe is provided at the center of the inner bottom wall of the conical inner liner.

[0008] Preferably, the limiting seat is provided with a screwing bolt on both sides, and a bearing seat is provided at one end of the screwing bolt.

[0009] Preferably, the inner sides of the limiting connector are provided with arc-shaped retaining seats through a screw and a bearing seat.

[0010] Preferably, a sealing ring is provided at the bottom of the mounting cover, and threaded holes are provided on all four sides of the mounting cover.

[0011] Preferably, the inner wall of the contraction ring seat is provided with an annular airbag cover, and the inner wall of the mounting sleeve is provided with a lateral distance probe.

[0012] Preferably, a fastening bolt is provided on the top side of the mounting bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This integrated real-time monitoring hydraulic cylinder, through its mounting bracket, side mounting bracket, mounting cover, shrink ring seat, air pump, sealing ring, threaded holes, annular airbag cover, side distance probe, and fastening bolts, allows for more integrated real-time monitoring of the hydraulic cylinder. In actual use, the operator first installs the hydraulic cylinder inside the mounting bracket, then fastens the mounting cover onto the mounting bracket, sealing the connection between the mounting bracket and the mounting cover using the sealing ring. The fastening bolts on the side mounting bracket are then tightened to the threaded holes on all four sides of the mounting cover, achieving rapid assembly and fixation. Simultaneously, by activating the air pump inside the shrink ring seat, the annular airbag cover is inflated, sealing it against the piston rod of the hydraulic cylinder. The side distance probe can then be fitted onto the piston rod for real-time monitoring. This comprehensive, protective, and enclosed monitoring system improves the monitoring effect and demonstrates the practicality of the equipment design.

[0014] This integrated real-time monitoring hydraulic cylinder, through its mounting bracket, limit seat, liquid-collecting bottom cover, mounting plate, conical inner liner, liquid measuring probe, tightening bolt, bearing seat, and arc-shaped retaining bracket, further improves the overall performance of the equipment. During daily use, after the hydraulic cylinder is installed inside the mounting bracket, its bottom end can be inserted into the limit seat. Tightening the tightening bolt, in conjunction with the bearing seat, locks the two sets of arc-shaped retaining brackets on both sides of the bottom of the hydraulic cylinder, enabling rapid fixing. Simultaneously, in case of oil leakage, the oil flows along the mounting bracket into the conical inner liner of the liquid-collecting bottom cover, where it is immediately monitored by the liquid measuring probe. Subsequent rapid replacement and maintenance operations are also possible, demonstrating the comprehensive design of the equipment. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 One embodiment provided by this utility model: An integrated real-time monitoring hydraulic cylinder includes a mounting bracket 1. Mounting side frames 2 are fixedly connected to the four sides of the mounting bracket 1. A monitoring component is movably connected to the top of the mounting bracket 1. The mounting component is located at the bottom of the mounting bracket 1. The monitoring component includes a mounting cover 3. The mounting cover 3 is movably connected to the top of the mounting bracket 1. A contraction ring seat 4 is located inside the mounting cover 3. A control air pump 5 is located on the back of the contraction ring seat 4. A sealing ring 14 is located at the bottom of the mounting cover 3. Threaded holes 15 are formed on the four sides of the mounting cover 3. An annular airbag cover 16 is located on the inner wall of the contraction ring seat 4. A lateral distance probe 17 is located on the inner wall of the mounting cover 3. A fastening bolt 18 is located on the top side of the mounting side frame 2. Activating the control air pump 5 inside the contraction ring seat 4 inflates the annular airbag cover 16, causing it to seal and fit onto the piston rod of the hydraulic cylinder. The lateral distance probe 17 can be fitted onto the piston rod for real-time monitoring of the piston rod.

[0019] The mounting assembly includes a limiting connector 6. The bottom end of the mounting sleeve 1 is fixedly connected to the limiting connector 6. The bottom end of the limiting connector 6 is fixedly connected to a liquid-coated bottom cover 7. The bottom end of the liquid-coated bottom cover 7 is fixedly connected to a mounting plate 8. The inner wall of the liquid-coated bottom cover 7 is provided with a conical inner liner 9. A liquid measuring probe 10 is provided at the center of the inner bottom wall of the conical inner liner 9. The limiting connector 6 is provided with a screw bolt 11 on both sides. A bearing seat 12 is provided at one end of the screw bolt 11. The inner sides of the limiting connector 6 are provided with arc-shaped retaining seats 13 through the screw bolt 11 and the bearing seat 12. The oil can flow into the conical inner liner 9 of the liquid-coated bottom cover 7 at the bottom end through the mounting sleeve 1, and can be monitored at the liquid measuring probe 10 in the first time. Subsequent quick replacement and maintenance operations can also be performed.

[0020] Working principle: During use, the operator first installs the hydraulic cylinder inside the mounting bracket 1, then fastens the mounting cover 3 onto the mounting bracket 1. A sealing ring 14 is used to seal the connection between the mounting bracket 1 and the mounting cover 3. The fastening bolts 18 on the side of the mounting side bracket 2 are then tightened to the threaded holes 15 on all four sides of the mounting cover 3, achieving a quick and easy assembly and fixation. Simultaneously, by starting the air pump 5 inside the shrink ring seat 4, the annular airbag cover 16 is inflated, sealing it against the piston rod of the hydraulic cylinder. The side distance probe 17 can be fitted onto the piston rod for real-time monitoring, providing overall protection. The protective closed monitoring improves the monitoring effect. In daily use, after the hydraulic cylinder is installed inside the mounting bracket 1, its bottom end can be inserted into the limit seat 6. Then, by turning the turning bolt 11, it cooperates with the bearing seat 12 to perform the limit clamping operation on both sides of the bottom end of the hydraulic cylinder, thus quickly fixing the hydraulic cylinder. At the same time, if the hydraulic cylinder leaks oil, the oil can flow along the mounting bracket 1 into the conical inner liner 9 of the bottom liquid collection cover 7, and be monitored immediately by the liquid measuring probe 10. Subsequent quick disassembly and maintenance operations can also be performed. The above is the complete working principle of this utility model.
