Technical Field

[0001] The utility model belongs to the technical field of disassembly and assembly tools, and particularly relates to a disassembly and assembly tool for a transformer tube type oil level gauge. Background Art

[0002] The transformer tube type oil level gauge is installed on the upper part of the transformer oil tank, used for detecting the oil level in the oil tank, and can release the pressure in the oil tank when the pressure in the oil tank increases to ensure the safety of the oil tank. A clamping groove is arranged on the circumferential side of the base of the transformer tube type oil level gauge, which facilitates the installation and disassembly of the transformer tube type oil level gauge on the upper part of the transformer oil tank. The existing disassembly and assembly tools for installing and disassembling the transformer tube type oil level gauge have short handles, which are not conducive to personnel operation; for different transformer tube type oil level gauges, the diameters of their bases are different. When the disassembly and assembly tools are applied to different transformer tube type oil level gauges, in order to facilitate the force on the base of the transformer tube type oil level gauge, other objects (such as pads) are usually used in combination. Only in this way can the installation and disassembly of the transformer tube type oil level gauge be smoothly realized. Moreover, the way of using other objects in combination has the problem that the cooperation between the objects and the disassembly and assembly tools is not coordinated, the disassembly and assembly tools have poor versatility and are inconvenient to use; the structure of the disassembly and assembly tools is complex, and it is more inconvenient to manufacture and use. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: to provide a disassembly and assembly tool for a transformer tube type oil level gauge to solve at least some of the above technical problems.

[0004] To achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0005] A disassembly and assembly tool for a transformer tube type oil level gauge includes a snap ring, a clamping block arranged at one end of the snap ring, a handle arranged at the other end of the snap ring, and an extended handle connected to the handle; a plurality of threaded through holes are opened on the snap ring, and screws are threadedly connected in the threaded through holes; the handle is flat, the extended handle is cylindrical, and the extended handle is welded to the side surface of the handle.

[0006] Further, the cross-section of the snap ring is rectangular.

[0007] Further, the cross-sectional area of the snap ring gradually increases along the direction from the clamping block to the handle.

[0008] Further, the top end of the clamping block bends towards the inner wall of the snap ring.

[0009] Further, the cross-sectional end surface of the top end of the clamping block is rectangular.

[0010] Further, anti-slip grooves are opened on both the upper and lower surfaces of the handle.

[0011] Further, through holes communicating the upper and lower surfaces of the handle are opened at one end of the anti-slip groove far away from the snap ring.

[0012] Furthermore, both ends of the anti-skid groove are semicircular.

[0013] Furthermore, the width of the handle gradually decreases in a direction away from the clamping ring, and one end of the handle away from the clamping ring is semicircular.

[0014] Furthermore, there are at least two welding points between the extended handle and the side surface of the handle.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model has a simple structure, a scientific and reasonable design, and is easy to manufacture and use. When the utility model is used, an extended handle is added to the handle, which solves the technical problem that the handle of the existing disassembly and assembly tool is short and is not conducive to human operation. The utility model adjusts the screw on the clamp ring so that a force-bearing part exists between the clamp ring and the outer wall of the base of the transformer tubular oil level gauge, so that the base of the transformer tubular oil level gauge rotates under the drive of the clamp ring through the transmission of force at the force-bearing part, thereby realizing the assembly and disassembly of the transformer tubular oil level gauge. The utility model is suitable for transformer tubular oil level gauges of many different pipe diameters and has strong versatility.

[0017] The inner wall of the clamping ring of the utility model is an arc shape smaller than a semicircular arc. Although the base diameter lengths of transformer tubular oil level gauges of different diameters are different, they are all cylindrical, and the outer wall of the base is all circular. After the clamping block is clamped into the clamping groove in the outer wall of the base of the transformer tubular oil level gauge, the screw on the clamping ring is properly screwed until the end of the screw close to the inner wall of the clamping ring touches the outer wall of the base. At this time, the contact part between the screw and the outer wall of the base is the force-bearing part, and then the handle is turned to drive the base to rotate.

[0026] Embodiment 1

[0027] As Figures 1 - 3 shown, a disassembly and assembly tooling for a transformer tube type oil level gauge provided by the present utility model includes a snap ring 1, a clamping block 2 provided at one end of the snap ring 1, a handle 3 provided at the other end of the snap ring 1, and an extended handle 4 connected to the handle 3; a plurality of threaded through holes 7 are formed in the snap ring 1, and a screw 8 is threadedly connected in the threaded through hole 7; the handle 3 is flat, the extended handle 4 is cylindrical, and the extended handle 4 is welded to the side surface of the handle 3.

[0028] In Embodiment 1 of the present invention, a clamping groove is provided on the peripheral side of the base of the transformer tube-type oil level gauge. When the present utility model is in use, the clamping block 2 is engaged into the clamping groove, and then the handle 3 is held by hand and rotated towards the outer wall of the base of the transformer tube-type oil level gauge, so that the clamping ring 1 gradually approaches the outer wall of the base of the transformer tube-type oil level gauge under the drive of the handle 3. When the rotation of the handle 3 ends and there is a gap between the inner wall of the clamping ring 1 and the outer wall of the base of the transformer tube-type oil level gauge, the screw on the clamping ring is appropriately screwed until the end of the screw close to the inner wall of the clamping ring touches the outer wall of the base of the transformer tube-type oil level gauge. At this time, the contact part between the screw and the outer wall of the base of the transformer tube-type oil level gauge is the stress part. After that, while keeping the screw 8 in contact with the outer wall of the base of the transformer tube-type oil level gauge, the force applied to the handle 3 is increased so that the clamping ring 1 drives the base of the transformer tube-type oil level gauge to rotate under the drive of the handle 3. Thus, the transformer tube-type oil level gauge is installed or removed from the upper part of the transformer oil tank.

[0029] In Embodiment 1 of the present invention, before the clamping ring 1 rotates, the end of the screw 8 close to the inner wall of the clamping ring 1 is located in the threaded through hole 7, and the end of the screw 8 close to the inner wall of the clamping ring 1 is screwed out of the threaded through hole 7 until it is needed.

[0030] The threaded through holes 7 are preferably three, and the three threaded through holes 7 are arranged along the direction of the clamping ring 1.

[0031] When the diameter of the transformer tube-type oil level gauge is large and it is not convenient to drive the rotation of the base of the transformer tube-type oil level gauge by holding the handle 3 by hand, the way of holding the lengthened handle 4 is adopted, so that the clamping ring 1 drives the base of the transformer tube-type oil level gauge to rotate under the drive of the lengthened handle 4. Thus, the transformer tube-type oil level gauge is installed or removed from the upper part of the transformer oil tank.

[0032] The structure of the present utility model is simple, scientifically reasonable in design, and convenient for manufacturing and use; when the present utility model is in use, a lengthened handle is added to the handle, solving the technical problem that the handle of the existing disassembly and assembly tool is too short and not conducive to personnel operation; by adjusting the screw on the clamping ring of the present utility model, a stress part exists between the clamping ring and the outer wall of the base of the transformer tube-type oil level gauge, so that the base of the transformer tube-type oil level gauge rotates under the drive of the clamping ring through the transmission of force by the stress part, and further the installation and disassembly of the transformer tube-type oil level gauge are realized. The present utility model is applicable to most transformer tube-type oil level gauges with different pipe diameters and has strong versatility.

[0033] Embodiment 2

[0034] As Figures 1 - 3As shown in the figure, a disassembly and assembly tooling for a transformer tube type oil level gauge provided by the present utility model includes a snap ring 1, a clamping block 2 provided at one end of the snap ring 1, a handle 3 provided at the other end of the snap ring 1, and an extension handle 4 connected to the handle 3; a plurality of threaded through holes 7 are opened on the snap ring 1, and a screw 8 is threadedly connected in the threaded through hole 7; the handle 3 is flat, the extension handle 4 is cylindrical, and the extension handle 4 is welded to the side surface of the handle 3.

[0035] One end of the screw 8 close to the inner wall of the snap ring 1 is hemispherical.

[0036] In this Embodiment 2, the outer wall of the base of the transformer tube type oil level gauge is an arc surface, and one end of the screw 8 close to the inner wall of the snap ring 1 is hemispherical. In this way, it is beneficial for the screw to contact the outer wall of the base of the transformer tube type oil level gauge.

[0037] Embodiment 3

[0038] As Figures 1 - 3 As shown in the figure, a disassembly and assembly tooling for a transformer tube type oil level gauge provided by the present utility model includes a snap ring 1, a clamping block 2 provided at one end of the snap ring 1, a handle 3 provided at the other end of the snap ring 1, and an extension handle 4 connected to the handle 3; a plurality of threaded through holes 7 are opened on the snap ring 1, and a screw 8 is threadedly connected in the threaded through hole 7; the handle 3 is flat, the extension handle 4 is cylindrical, and the extension handle 4 is welded to the side surface of the handle 3.

[0039] The cross-sectional area of the snap ring 1 gradually increases along the direction from the clamping block 2 to the handle 3.

[0040] In this Embodiment 3, the cross-sectional area of the snap ring 1 gradually increases along the direction from the clamping block 2 to the handle 3. The closer the snap ring 1 is to the handle 3, the larger its cross-sectional area. It can be seen that the closer the snap ring 1 is to the handle 3, the thicker its thickness. In this way, the strength of the connection between the snap ring 1 and the handle 3 can be enhanced. The connection between the snap ring 1 and the handle 3 is a key part for the movement transmission between the snap ring 1 and the handle 3. Enhancing the strength of the connection between the snap ring 1 and the handle 3 is beneficial to increase the service life of the present utility model.

[0041] Embodiment 4

[0042] As Figures 1 - 3 As shown in the figure, a disassembly and assembly tooling for a transformer tube type oil level gauge provided by the present utility model includes a snap ring 1, a clamping block 2 provided at one end of the snap ring 1, a handle 3 provided at the other end of the snap ring 1, and an extension handle 4 connected to the handle 3; a plurality of threaded through holes 7 are opened on the snap ring 1, and a screw 8 is threadedly connected in the threaded through hole 7; the handle 3 is flat, the extension handle 4 is cylindrical, and the extension handle 4 is welded to the side surface of the handle 3.

[0043] The top end of the clamping block 2 bends towards the inner wall of the snap ring 1.

[0044] In Embodiment 4, after the clamping block 2 is clamped into the clamping groove, when holding the handle 3 and rotating it towards the outer wall of the base of the transformer tube-type oil level gauge, during the process that the inner wall of the clamping ring 1 fits against the outer wall of the base of the transformer tube-type oil level gauge, the clamping block 2 will rotate in the direction opposite to the rotation direction of the clamping ring 1 in the clamping groove. The displacement of the clamping block 2 in the clamping groove causes the clamping block 2 to be unstably clamped in the clamping groove. When the force applied to the handle 3 is too large, the clamping block 2 may slide out of the clamping groove before the operator reacts. The operator may, due to inertia, cause the sliding clamping block 2 to scrape a scratch on the outer wall of the base of the transformer tube-type oil level gauge. The top end of the clamping block 2 is bent towards the inner wall of the clamping ring 1. Thus, when the clamping block 2 may slide out of the clamping groove, the top end of the clamping block 2 can grip the side wall of the clamping groove during the sliding process of the clamping block 2, hindering the clamping block 2 from sliding out of the clamping groove, thereby leaving a reaction time for the operator.

[0045] Embodiment 5

[0046] As Figures 1 - 3 shown, a disassembly and assembly tool for a transformer tube-type oil level gauge provided by the present utility model includes a clamping ring 1, a clamping block 2 provided at one end of the clamping ring 1, a handle 3 provided at the other end of the clamping ring 1, and an extended handle 4 connected to the handle 3; a plurality of threaded through holes 7 are formed on the clamping ring 1, and a screw 8 is threadedly connected in the threaded through hole 7; the handle 3 is flat, the extended handle 4 is cylindrical, and the extended handle 4 is welded to the side surface of the handle 3.

[0047] The top end of the clamping block 2 is bent towards the inner wall of the clamping ring 1.

[0048] The end face of the top end of the clamping block 2 is rectangular.

[0049] Based on Embodiment 4, in Embodiment 5, when the clamping block 2 may slide out of the clamping groove and the top end of the clamping block 2 grips the side wall of the clamping groove during the sliding process of the clamping block 2, the end face of the top end of the clamping block 2 is rectangular, which can increase the contact area between the top end of the clamping block 2 and the side wall of the clamping groove and prevent the top end of the clamping block 2 from damaging the side wall of the clamping groove.
