The present invention allows one person to safely, reliably, and labor-savingly replace the filter element of a hydraulic system filter. Most existing filter element replacement devices can only support the filter element housing and assist in filter element replacement. When installing a new filter element, the filter element needs to be positioned manually, which is not conducive to the corresponding installation of the filter element and the plug-in installation position, resulting in slow replacement efficiency.

[0003] Based on this, the utility model designs an efficient replacement device for the hydraulic filter element to solve the problem. Utility Model Content

[0004] The purpose of the utility model is to provide an efficient replacement device for a hydraulic filter element to solve the above technical problems.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-efficiency replacement device for a hydraulic filter element, which arranges a positioning assembly between the frame and the filter element support assembly, so that after the replacement filter element is installed on the filter element support assembly that is rotated out of the frame, the filter element support assembly that is rotated into the frame is positioned by the positioning assembly, ensuring that the filter element positioning assembly rotates and moves to be coaxial with the frame, which is conducive to the mutual connection and fixation of the filter element fixed on the filter element support assembly and the hydraulic oil tank.

[0006] By adopting the above technical solution, the first elastic member can be made of a material with elastic deformation. The first elastic member is respectively engaged with the plurality of first slots arranged around the hinge axis, thereby facilitating the positioning of the rotation angle of the filter element support assembly.

[0007] By adopting the above technical solution, the first telescopic assembly can be made of an electric telescopic rod. The first telescopic assembly extends to move the fixed ring. When installing the filter element, the fixed ring moves upward to move the filter element detachably connected to the fixed ring and insert it into the hydraulic oil tank. The fixed ring and the plug interface are coaxially arranged to ensure that the filter element fixed in the middle of the fixed ring and the plug interface match each other.

[0008] By adopting the above technical solution, multiple groups of clamps are arranged in a ring shape at equal intervals around the central axis of the fixed ring, and multiple groups of first clamps extend toward the middle of the fixed ring under the control of the second telescopic component, making it easier to clamp and fix the filter element using the second clamps.

[0009] By adopting the above technical solution, a groove with an opening facing the fixing ring is provided on the bottom plate, which can receive the leaked liquid when the old filter element is disassembled, thereby avoiding leakage contamination.

[0010] By adopting the above technical solution, the support ring and the filter housing are detachably connected to each other, and the filter housing passes through the through groove in the middle of the connecting ring. When the filter housing is disassembled, it moves downward under the drive of the support ring, passing through the middle of the connecting ring, thereby preventing the filter housing from obstructing the replacement of the filter element.

[0011] By adopting the above technical solution, the support ring drives the second clamping plate to move through the third telescopic assembly to abut and match with the outer wall of the filter housing, thereby clamping and fixing the filter housing.

[0012] Compared with the existing technology, the beneficial effect of the present invention is that the present invention facilitates the positioning of the filter element support assembly by arranging a positioning assembly between the filter element support assembly and the frame, so that the filter element fixed on the filter element support assembly matches and corresponds to the plug-in installation position.

The fixing assembly 2 is arranged at the top of the frame 1, the filter housing support assembly 3 is arranged at the bottom of the frame 1, and the filter element support assembly 4 is arranged between the fixing assembly 2 and the filter housing support assembly 3. The filter element support assembly 4 and the frame 1 are rotatably matched with each other. A positioning assembly 5 is provided between the filter element support assembly 4 and the frame 1. The positioning assembly 5 is used to position the filter element provided in the filter element support assembly 4. By providing a positioning assembly between the frame and the filter element support assembly, after the replacement filter element is installed on the filter element support assembly that is rotated out of the frame, the filter element support assembly that is rotated into the frame is positioned by the positioning assembly, ensuring that the filter element positioning assembly rotates and moves to be coaxial with the frame, which is conducive to the mutual connection and fixation of the filter element fixed on the filter element support assembly and the hydraulic oil tank.

[0022] Reference Figure 1 、 2 As shown in Figures 3 and 4, the positioning assembly 5 includes a first elastic member 51 and multiple groups of first slots 52. The first elastic member 51 is disposed at the end of the frame 1 away from the fixing assembly 2. The first elastic member 51 is disposed near the hinge axis between the filter element support assembly 4 and the frame 1. The multiple groups of first slots 52 are disposed at the bottom of the filter element support assembly 4 and are disposed around the hinge axis between the filter element support assembly 4 and the frame 1. The first elastic member 51 is respectively engaged with the multiple groups of first slots 52. The first elastic member can be made of a material with elastic deformation. By engaging the first elastic member with the multiple groups of first slots disposed around the hinge axis, the rotation angle of the filter element support assembly can be positioned.

[0023] Reference Figure 1 、 2 As shown, the filter element support assembly 4 comprises a base 41 and a bottom plate 42. Base 41 is rotatably connected to the frame 1. The bottom plate 42 is fixed to the end of the base 41 away from the fixed assembly 2.

The inner wall of the retaining ring 43 is provided with multiple sets of first clamping plates 45, arranged equidistantly in a ring around the central axis of the retaining ring 43. A second telescopic assembly 46 is positioned between the first clamping plates 45 and the inner wall of the retaining ring 43. A groove 47 is provided on the bottom plate 42, opening upward. The first telescopic assembly can be a motorized telescopic rod. Extension of the first telescopic assembly drives the retaining ring. During filter element installation, the retaining ring moves upward, driving the filter element, which is detachably connected to the retaining ring, into the hydraulic oil tank. The retaining ring and the plug-in port are coaxially arranged, ensuring that the filter element, which is fixed in the middle of the retaining ring, mates with the plug-in port. Multiple sets of clamping plates are arranged in a circular pattern, equidistantly around the central axis of the retaining ring. Controlled by a second telescoping assembly, multiple sets of first clamping plates extend toward the center of the retaining ring, facilitating the use of second clamping plates to secure the filter element. A groove opening toward the retaining ring is located on the bottom plate to catch any leaking liquid when removing the old filter element, preventing contamination.

[0024] Reference Figure 1 、 2 As shown, the filter housing support assembly 3 includes a connecting ring 31, which is fixed to the first end of the frame 1 away from the fixing assembly 2.

The support ring and the filter housing are detachably connected to each other, and the filter housing passes through the middle groove of the connecting ring. When the filter housing is completely disassembled, it moves downward under the drive of the support ring, so that it passes through the middle of the connecting ring, thereby preventing the filter housing from obstructing the replacement of the filter element. The support ring drives the second clamping plate to move through the third telescopic assembly to abut and match the outer wall of the filter housing, thereby clamping and fixing the filter housing.

[0025] Specific application examples of this utility model:

[0026] By setting a positioning assembly between the frame and the filter element support assembly, after the replacement filter element is installed on the filter element support assembly that is rotated out of the frame, the filter element support assembly that is rotated into the frame is positioned by the positioning assembly, ensuring that the filter element positioning assembly rotates and moves to be coaxial with the frame, which is conducive to the mutual connection and fixation of the filter element fixed on the filter element support assembly and the hydraulic oil tank.
