Description

Technical Field

[0001] The present application relates to the technical field of filter element disassembly devices, and in particular to a filter element screw-on wrench. Background Art

[0002] Oil separator is an important equipment in the processing of ship lubricating oil and fuel oil. It is mainly used to separate water, impurities and particles in the oil to ensure the quality of lubricating oil and fuel oil.

[0003] When the oil separator is performing oil residue separation, the oil residue is generally filtered through a filter element in the filter part of the oil separator. After the filter element has worked for a long time, it is generally necessary to rotate and replace the filter element.

[0004] At present, when the filter element is rotated and replaced, the staff usually directly twists the filter element with both hands. When twisting the filter element, sometimes it is difficult to apply force to the filter element due to the small contact area between the hands and the filter element, thereby making it difficult to rotate and replace the filter element.

[0027] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0028] The embodiment of the present application discloses a filter element rotating wrench.

[0029] A filter element screw-on wrench comprises a handle 1 and a locking assembly 2. The locking assembly 2 is detachably mounted on the handle 1. When the filter element needs to be screwed on, the locking assembly 2 is mounted on the handle 1, and the locking assembly 2 is used to clamp the filter element. Then, the operator drives the locking assembly 2 to rotate through the handle 1 to screw on the filter element.

[0030] The handle 1 includes a hand-holding portion 11 and a transmission portion 12 .

[0031] The hand-held portion 11 includes a hand-held rod 111 and a positioning member 112. The hand-held rod 111 can be a round rod or a square rod. In the embodiment of the present application, the hand-held rod 111 is a square rod to facilitate the installation of the positioning member 112. At the same time, in order to improve the comfort of the staff holding the hand-held rod 111, a plurality of grooves 113 are provided on the hand-held rod 111. The plurality of grooves 113 are distributed along the length direction of the hand-held rod 111, and the inner wall of each groove 113 is an arc surface.

[0032] In the embodiment of the present application, the positioning member 112 is a positioning block, and the positioning block is fixedly mounted on the side wall of the hand-held rod 111. The cross section of the positioning block is a polygon, and in the embodiment of the present application, the positioning block is a rectangular block.

[0033] The transmission part 12 includes a plurality of transmission units. Each transmission unit includes a transmission rod 121 and a limit block 122. A limit slot 123 is provided at one end of the transmission rod 121. The limit slot 123 is a polygonal slot. In the embodiment of the present application, the limit slot 123 is a quadrilateral slot.

[0034] The limit block 122 is fixedly mounted on one end of the transmission rod 121 away from the limit slot 123. In the embodiment of the present application, the limit block 122 is a rectangular block. When assembling two adjacent transmission units, the limit block 122 and the adjacent limit slot 123 can be plugged and matched, so as to facilitate the needs of transmission parts 12 of different lengths. When the transmission part 12 is not needed, the transmission part 12 is disassembled into multiple transmission units, so as to facilitate the storage and carrying of multiple transmission parts 12. When connecting the hand-held rod 111 and the transmission part 12, the positioning block on the hand-held rod 111 can be inserted into the adjacent limit slot 123.

[0035] The locking assembly 2 includes a locking belt 21 and a locking member 22. The locking belt 21 is a bendable belt-like object. In actual operation, a bendable belt-like object such as a strapping belt can be selected from nearby materials. In order to reduce the possibility of damage to the filter element during the process of clamping the filter element, an elastic pad 211 is also placed on the locking belt 21 to buffer the extrusion force received by the outer peripheral surface of the filter element.

[0036] In the embodiment of the present application, the locking member 22 is a locking bolt. A locking groove 124 is provided on the limiting block 122. When the locking belt 21 needs to be connected, the two ends of the locking belt 21 are passed through the locking groove 124, and the locking belt 21 is limited by the locking groove 124. Then, the two ends of the locking belt 21 are pressed against the inner wall of the limiting groove 123 by the locking bolt, so as to improve the convenience and stability of connecting the locking belt 21.

[0037] The implementation principle of the filter element screw-on wrench of the embodiment of the present application is as follows: when the filter element needs to be screwed on, different numbers of transmission rods 121 are selected according to the required length, and the limit blocks 122 and the positioning blocks are inserted into the adjacent limit grooves 123, and then the two ends of the locking belt 21 are pressed against the limit blocks 122 by the locking bolts, and the locking belt 21 is sleeved on the outer peripheral surface of the filter element. Then, the staff drives the transmission part 12 to rotate through the hand-held rod 111, so that the locking belt 21 shrinks during the rotation process and clamps the filter element, and then the hand-held rod 111 drives the filter element to rotate again through the locking belt 21, so that the filter element is screwed on, thereby improving the convenience of screwing the filter element.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
