As shown in Figure 1, Figure 9, Figure 10 and Figure 11, a multi-directional adjustment mobile vehicle for indoor current transformer installation according to the present invention includes a vertical lifting assembly 1, a horizontal fine-tuning assembly 2 and a base assembly 3. The vertical lift assembly 1 is used for wide-range height adjustment, the horizontal fine-adjustment assembly 2 is used for placing current transformers and making small-scale adjustments, and the base assembly 3 is used for supporting and moving the vertical lift assembly 1 . As shown in Figure 2, the vertical lifting assembly 1 includes a threaded rod 14 and a sleeve 10 fixedly installed on the base assembly 3. Various ways such as welding are installed on the base assembly 3 . The movable groove 13 can only be provided with one or two. If only one is provided, only one side can only be fixed when the horizontal connector 12 and the bolt block 18 are installed. The purpose of the movable groove 13 is to limit the horizontal connection. The movement of the component 12 is such that it can only move up and down and it is guaranteed that the range of motion will not be too high or too low. As shown in FIG. 5 , a turning handle 16 is provided on the top of the threaded rod 14 , and the threaded rod 14 and the turning handle 16 are integrated. The turning handle 16 passes through the cylinder cover 11 and forms a rotation fit with it. The way of forming the rotation fit is a variety of ways in the prior art. The protrusion is stuck in the card slot and the upper and lower limits can only be rotated, and another example is the design of the principle of rivets. A bolt block 18 is installed in the middle part of the threaded rod 14 , and the bolt block 18 is threadedly mounted on the threaded rod 14 . The sleeve 10 is set on the threaded rod 14 and fixedly installed with the cover 11. When the sleeve 10 is set on the threaded rod 14, the cover 11 is set on the sleeve 10 and fixed by screw, welding, clamping and other methods Installation, of course, welding is not convenient for later equipment disassembly. The sleeve 10 is covered with a horizontal connecting piece 12, as shown in FIG. The mounting hole 15 of the horizontal connector 12 is installed through the movable groove 13 and the bolt block 18 by a screw. The motion of 18 must move up and down within the scope of movable groove 13, and the 2nd, can drive the motion of horizontal connector 12 in order to guarantee that the motion of bolt block 18. As shown in Figure 11, the number of movable grooves 13 can be two, if it is one, the basic function of limiting and the fixing function of the horizontal connector 12 and the bolt block 18 are realized; Both the left and right ends of the cylinder 10 are provided with movable grooves 13, so that the connection between the horizontal connecting piece 12 and the bolt block 18 can also be connected at both the left and right ends of the sleeve 10, and the stabilizing effect is better. The horizontal fine-tuning assembly 2 is fixedly installed on the horizontal connecting piece 12, thereby realizing a wide range of height adjustment.

During the installation of the current transformer, the angle error between the current transformer fixing hole and the bolt hole in the switch cabinet should be very small, so it is necessary to accurately adjust the angle of the loading platform in all directions to ensure accuracy; at the same time, it is necessary to consider Safety, that is, when the current transformer is placed on the platform, the platform should be stable, and there should be no safety accidents in which the equipment slips and the personal equipment is injured. As shown in FIG. 6 , the horizontal fine-tuning assembly 2 includes a platform 20 and a fine-tuning platform 21 , the platform 20 is used for placing a current transformer, and the fine-tuning platform 21 is used for fine-tuning the platform 20 in conjunction with a rotating threaded rod 24 . Rotating threaded rods 24 are respectively installed at the inner corners below the platform 20, and the rotating threaded rods 24 are installed under the platform 20 according to the prior art to realize the rotating function of the rotating threaded rods 24, for example, welding under the platform 20 Nut, the rotating threaded rod can be rotated on the nut; for another example, design a groove below the cap 20, design a protrusion on the top of the rotating threaded rod, and the groove cooperates with the protrusion to realize the rotation of the rotating threaded rod. The upper and lower limits are fixed and can only be rotated. The quantity of rotating threaded rod 24 is 4, is installed in respectively at the four interior corners below bearing platform 20, and the bottom of rotating threaded rod 24 is fixedly equipped with turning handle 25, drives rotating threaded rod 24 to rotate by turning handle 25. The four inner corners below the fine-tuning table 21 are respectively equipped with support bars 23, and the number of support bars 23 is four. The support bars 23 are installed on the rotating threaded rods 24 respectively, that is, the supporting bars 23 are threadedly mounted on the rotating threaded rods 24, so that the rotation of the rotating threaded rods 24 can drive the supporting bars 23 to move up and down, thereby realizing the platform 20 based on fine adjustment. The up and down small range motion of platform 21. The side of the fine-tuning platform 21 is fixedly installed with an intermediate piece 22, which is welded together with the fine-tuning platform 21, and the intermediate piece 22 is fixedly installed with the horizontal connecting piece 12, thereby realizing the fixed installation of the horizontal fine-tuning assembly 2 and the vertical lifting assembly 1 connect.

As shown in FIGS. 7 and 8 , the base assembly 3 includes a mobile chassis 30 , guide wheels 31 and universal wheels 32 . In order to move more conveniently, the quantity of guide wheel 31 is 2, and the quantity of universal wheel 32 is 2, and guide wheel 31 is respectively installed in the inner angle place of mobile chassis 30 left side bottoms, and universal wheel 32 is installed in mobile chassis 30 At the lower inner corner on the right. If the four wheels are all guide wheels, it is impossible to change the direction of the car. If the four wheels are all universal wheels, the movement will be unstable, which will easily cause the current transformer to slip. Sleeve 10 is installed on mobile chassis 30 tops near universal wheel 32 places, and the front has guaranteed advancing direction for guide wheel like this when moving, and rear provides change of direction for universal wheel under the premise of guaranteeing stability.

In order to facilitate the rotation of the threaded rod 14, a movable handle 17 may also be included, and the movable handle 17 passes through the rotating handle 16 and forms a clearance fit with it. Movable handle 17 can move back and forth on rotating handle 16 like this, when needing which direction exerts oneself, then increase the moment of that direction. In order to better cooperate with the installation and connection of the current transformer in the cabinet, the length of the movable slot 13 can be 300mm, the length of the sleeve 10 can be 530mm, and the length of the vertical lift assembly 1 can be 600mm, which can match the height of the cabinet. The length of the rotating threaded rod 24 is 150mm, which ensures that the fine-tuning height is moderate, the angle adjustment range is large and there is no deformation.

In actual use, first measure the installation height that the current transformer in the cabinet also needs, and rotate the movable handle 17 to drive the threaded rod 14 to rotate. Because the bolt block 18 on the threaded rod 14 is limited in the movable groove 13 by the horizontal connector 12, the rotation of the threaded rod 14 cannot drive the bolt block 18 to rotate, but can only drive the bolt block 18 to move up and down according to the threads on the threaded rod 14. Thereby driving the horizontal fine-tuning assembly 2 to move up and down. After the vertical lift assembly 1 is adjusted in place, the base assembly 3 is used to push it to the side of the cabinet. Put the current transformer on the platform 20, and adjust the horizontal fine-tuning assembly 2 for fine-tuning. Respectively rotate the handle 25 and hold the support bar 23 by hand to drive the rotating threaded rod 24 to rotate. The support bar 23 is fine-tuned up and down on the rotating threaded rod 24 according to the thread, thereby realizing the up and down micro-motion of an inner angle of the horizontal fine-tuning assembly 2, and then Adjust the other three rotating threaded rods 24 respectively as required. After the adjustment is in place, the connection and installation of the current transformers are carried out. According to actual calculations, only 2 people are required to replace a set of 35kV indoor current transformers, and the average time is reduced from 7.7 hours to 2.2 hours. Not only the replacement time is shortened, but also the site safety is under control, no need to manually lift heavy equipment, avoiding safety accidents of equipment falling and hurting people and equipment.
