[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0032] Example 1, reference Figures 1 to 3 , which is the first embodiment of the present utility model, provides a transformer inspection tool, which includes a vehicle-mounted unit 100, a lifting unit 300 for lifting the transformer housing is provided above the vehicle-mounted unit 100, and an adjustment unit 200 for changing the angle of the transformer housing is provided above the lifting unit 300;

[0033] The vehicle-mounted unit 100 includes a frame 101, a C-shaped groove 1011 is symmetrically provided on the inner side of the frame 101, and two sets of extension mechanisms are symmetrically provided at one end of the frame 101, and the extension mechanism is a No. 1 hydraulic telescopic rod 102;

[0034] The lifting unit 300 includes a C-shaped plate 301, a support frame 304 is fixedly connected to the middle position of the C-shaped plate 301, a support rod 305 is fixedly connected to the upper part of the support frame 304, and a semicircular boss 307 is fixedly connected to one end of the support rod 305;

[0035] The adjustment unit 200 includes an L-shaped bracket 201, one end of which is provided with an adjustment mechanism 203 for cooperating with a semicircular boss 307 to achieve the angle of the transformer housing. Two sets of Y-shaped tubes 302 are symmetrically fixedly connected to the lower end surface of one end of the C-shaped plate 301. The telescopic end of the first hydraulic telescopic rod 102 is located within the Y-shaped tube 302. The first hydraulic telescopic rod 102 and the C-shaped plate 301 are connected by the Y-shaped tube 302.

[0036] The C-shaped groove 1011 is designed so that when the transformer housing is lifted, its mounting base can pass through the C-shaped groove 1011 smoothly, avoiding the frame 101 from blocking the mounting base and making it impossible for the transformer housing to be lifted. Figure 1 As shown, the C-shaped plate 301 can be inserted between the upper end cover and the heat sink of the transformer housing under the drive of the vehicle-mounted unit 100 and cooperate with the lifting of the No. 1 hydraulic telescopic rod 102 to achieve the lifting of the transformer housing. The Y-shaped tube 302 is used to cooperate with the alignment of the telescopic end of the No. 1 hydraulic telescopic rod 102, so that the No. 1 hydraulic telescopic rod 102 can be quickly inserted into the Y-shaped tube 302 and support or lift the C-shaped plate 301;

[0037] When using, such as Figure 1As shown, first, by starting the on-board unit 100 and reversing in the direction of the transformer casing, the frame 101 and the C-shaped plate 301 are respectively inserted into the upper and lower sides of the heat sink in the front and rear directions of the transformer casing. Then, the No. 1 hydraulic telescopic rod 102 is controlled to rise and push the C-shaped plate 301 to rise. The C-shaped plate 301 drives the transformer casing to rise through the upper end cover of the transformer casing. At the same time, the C-shaped plate 301 drives the semicircular boss 307 to rise. When the semicircular boss 307 is engaged with the inside of the adjustment mechanism 203, the No. 1 hydraulic telescopic rod 102 is controlled to retract, and the No. 1 hydraulic telescopic rod 102 is separated from the Y-shaped tube 302. At this time, the C-shaped plate 301 and the transformer casing can rotate freely. The staff can stand in a suitable position to inspect the transformer casing by manually rotating the direction of the transformer casing. In addition, the equipment can quickly load and transport the transformer casing, thereby improving the practicality of the equipment and the efficiency of work.

[0038] Example 2, further optimizes the transformer inspection tool provided in Example 1, referring to Figures 3 and 4 The adjustment mechanism 203 includes an adjustment mechanism housing 2031 rotatably connected to one end of the L-shaped bracket 201. An adjustment slot 2032 and a spring slot 2033 are formed inside the adjustment mechanism housing 2031. The adjustment slot 2032 and the spring slot 2033 are interconnected. One end of the spring slot 2033 passes through the adjustment mechanism housing 2031 and is in communication with the outside.

[0039] The adjusting groove 2032 is used to accommodate the semicircular boss 307 , and the semicircular boss 307 can move up and down in the adjusting groove 2032 .

[0040] Furthermore, a T-shaped rod 2035 is inserted into the spring groove 2033, one end of which is fixedly connected to a wedge block 2034. A spring is sleeved on the outer wall of the T-shaped rod 2035, and a cone 306 is slidably connected to the outer wall of the support rod 305. The cone 306 is located at the lower end of the semicircular boss 307.

[0041] Among them, the wedge block 2034 is used to cooperate with the semicircular boss 307 to limit the height of the transformer casing, and the contact between the wedge block 2034 and the horizontal surface of the semicircular boss 307 allows the semicircular boss 307 to rotate freely relative to the surface of the wedge block 2034, thereby achieving free rotation of the C-shaped plate 301 and the transformer casing. The spring can be used to reset the wedge block 2034, and the cone 306 is used to cooperate with the wedge block 2034 to unlock the semicircular boss 307, so that the wedge block 2034 no longer limits the height of the transformer casing.

[0042] When the semicircular boss 307 is in use, it moves toward the inside of the adjustment groove 2032, and the arc surface of the semicircular boss 307 contacts and squeezes the wedge surface of the wedge block 2034. The wedge block 2034 is subjected to the lateral component of the force from the semicircular boss 307, so that the wedge block 2034 is squeezed into the spring groove 2033 by the semicircular boss 307. The spring is squeezed and obtains a restoring force. When the semicircular boss 307 moves to the top of the wedge block 2034, the semicircular boss 307 no longer squeezes the wedge block 2034. Under the action of the restoring force of the spring, the wedge block 2034 is reset and the semicircular boss 307 is locked in place, so that the semicircular boss 307 will not fall when it is not supported by external forces.

[0043] When the inspection work is completed, the No. 1 hydraulic telescopic rod 102 can be controlled to rise, and the semicircular boss 307 and the cone 306 can be pushed to continue to rise. After the cone 306 passes through the wedge block 2034, the wedge block 2034 is pressed on the arc surface below the cone 306 under the action of the spring restoring force, and the friction force on the cone 306 from the wedge block 2034 is greater than the gravity of the cone 306 itself. Then, by controlling the contraction of the No. 1 hydraulic telescopic rod 102, the semicircular boss 307 starts to move downward, and the cone 306 is pressed against the wedge block 2034. Under the action of the friction force generated by the extrusion, the cone 306 does not move downward and maintains a relative position until the lower horizontal surface of the semicircular boss 307 contacts the upper horizontal surface of the cone 306. The friction force exerted on the cone 306 by the wedge block 2034 is smaller than the sum of the gravity of the cone 306 itself and the reverse extrusion force of the semicircular boss 307 on the cone 306, so that the wedge block 2034 is squeezed into the spring groove 2033. At this time, the wedge block 2034 is no longer limited by the wedge block 2034, and the height limit of the transformer housing is achieved by contact.

[0044] Example 3, further optimizes the transformer inspection tool provided in Example 1 or 2, referring to Figure 3 The upper surface of one end of the C-shaped plate 301 is fixedly connected to an L-shaped baffle 303, the adjustment mechanism housing 2031 is rotatably connected to one end of the L-shaped bracket 201, and a second hydraulic telescopic rod 202 is provided between the outer wall of the adjustment mechanism housing 2031 and the outer wall of the L-shaped bracket 201;

[0045] The L-shaped baffle 303 is used to match the angle deflection of the transformer housing to prevent the transformer housing from sliding;

[0046] When in use, by controlling the extension of the No. 2 hydraulic telescopic rod 202 and pushing the adjustment mechanism housing 2031 to one side, the adjustment mechanism housing 2031 deflects along the rotating connection point at its other end, thereby achieving the bottom of the transformer housing being driven to tilt outward through the adjustment mechanism 203, making it easier for staff to inspect the bottom of the transformer housing.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
