DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model.

[0020] The utility model provides a technical solution: as Figure 1 , Figure 2 ,Figure 3 and Figure 4 As shown in Figure 4 , in this embodiment, an intelligent detection device for the pump head of a hydraulic station of an aluminum electrolysis multifunctional crane includes a pressure gauge 1. A pressure measuring hose 2 is provided at the bottom of the pressure gauge 1. One end of the pressure measuring hose 2 is provided with a sealing component. The sealing component includes a nipple 7 installed at one end of the pressure measuring hose 2. A sealing ring 12 is provided at the bottom outside of the other end of the nipple 7. The inner diameters of the openings at both ends of the nipple 7 are not equal. One end of the nipple 7 is threadedly connected to the end of the pressure measuring hose 2. A fixing sleeve 8 is installed outside the bottom of the nipple 7. A limiting collar 9 is sleeved at the end of the fixing sleeve 8. The inner diameter of the top of the limiting collar 9 is larger than the outer diameter of the end of the fixing sleeve 8. Threads are provided on the outer surface of the fixing sleeve 8. The other end of the limiting collar 9 is connected to the fixing sleeve 8 by threads. A limiting ring groove 11 is provided on one end surface of the limiting collar 9. An airbag ring 10 is provided inside the limiting ring groove 11. The surface of the airbag ring 10 is adhesively connected to the inner bottom surface of the limiting ring groove 11, which is convenient for improving the sealing performance when the pressure measuring hose 2 is connected to the pump head of the hydraulic station, so that no gas leakage occurs during the pressure measurement process of the pressure gauge 1, which is convenient for improving the accuracy of the test results and has good practical effects.

[0021] As Figure 1 and Figure 2 As shown in Figure 2 , a storage component is provided outside the pressure measuring hose 2. The storage component includes a mounting sleeve 4 provided outside the pressure measuring hose 2. A connecting plate 5 is provided on one side of the mounting sleeve 4. Limiting card slots 6 for clamping the pressure measuring hose 2 are symmetrically provided on the surface of the connecting plate 5. One end of the connecting plate 5 is rotatably connected to the mounting sleeve 4. Limiting magnetic sleeves 3 are sleeved on both ends outside the pressure measuring hose 2. The surfaces of the two limiting magnetic sleeves 3 have different magnetic properties, which is convenient for achieving the purpose of limiting storage when the detection device is not in use. Workers can wind up the pressure measuring hose 2, which is simple and easy to operate, avoiding the situation that the pressure measuring hose 2 is scattered, so that the pressure measuring hose 2 is not easily damaged and has good practicality.

[0022] The utility model provides an intelligent detection device for the pump head of a hydraulic station of an aluminum electrolysis multifunctional crane. The specific working principle is as follows: When the utility model is not in use, workers need to limit and store the pressure measuring hose 2. At this time, the worker can wind up the pressure measuring hose 2 and snap it into the internal limit card slot 6 on the surface of the connecting plate 5. After winding up the pressure measuring hose 2 to a certain number of turns, the limit magnetic sleeves 3 at both ends of the outside of the pressure measuring hose 2 can be pulled, so that the two limit magnetic sleeves 3 gradually approach until the surfaces of the two limit magnetic sleeves 3 are magnetically connected, thereby enabling the pressure measuring hose 2 to be limited and stored. This is convenient for workers to store the detection device, preventing the pressure measuring hose 2 from being scattered and not easily damaged. The operation is convenient and fast, and the practicability is good. When the utility model needs to be detected, first, the pressure measuring hose 2 needs to be installed and connected to the pump head of the hydraulic station. At this time, the plug of the lubrication standby connection point of the pump head of the hydraulic station needs to be removed. Then, the screw pair 7 at one end of the pressure measuring hose 2 can be installed and connected to the pump head of the hydraulic station. At this time, the screw pair 7 will be threadedly connected to the pump head of the hydraulic station, and the surface of the sealing ring 12 will be pressed and fitted with the surface of the pump head of the hydraulic station. Then, the limit collar 9 outside the fixed sleeve 8 can be rotated, so that one end surface of the limit collar 9 gradually approaches the surface of the pump head of the hydraulic station until the surface of the airbag ring 10 inside the limit ring groove 11 is closely fitted with the surface of the pump head of the hydraulic station, thereby improving the sealing performance of the installation connection between the pressure measuring hose 2 and the pump head of the hydraulic station. The data can be directly read through the pressure gauge 1 of the intelligent detection tool for the pump head. The overflow valve group of the pump head and the shaft seal of the pump head can be adjusted in time for the abnormal hydraulic station to ensure the normal operation of the pump head of the hydraulic station, meet the production needs, improve the automation degree of the equipment, and at the same time improve and eliminate the safety hazards during the operation of the equipment maintenance personnel and reduce the labor intensity of the equipment maintenance personnel. The practical effect is good.

The scope of the present invention is defined by the appended claims and their equivalents.
