Description

Technical Field

[0001] The utility model relates to the field of transformer substations, in particular to a mobile bracket of a box-type transformer substation. Background Art

[0002] Substations are places in power systems that transform, concentrate and distribute electrical energy. The main function of a substation is to change the voltage to meet the needs of different parts of the power system. For example, the electricity generated by a power plant is usually high voltage, which needs to be boosted by a substation and then transported to a distant place. When it reaches the vicinity of the user, the voltage is then reduced to meet the voltage requirements of various electrical equipment.

[0003] Under normal circumstances, only one substation is needed. However, the power supply of the substation may fail, or when the demand is too high during peak hours, a secondary substation may be needed to replace or assist the main substation in time. However, the existing substation mobile bracket can generally only fix one substation. Utility Model Content

[0004] In view of the above-mentioned defects, the utility model provides a box-type substation mobile bracket, which can be more conveniently and directly applied to the installation and movement of a single or a main and auxiliary double substation.

Therefore, the directional terms used are used to illustrate and are not used to limit the utility model. In addition, in all embodiments, the same figure numbers represent the same elements.

[0025] like Figures 1 to 4 A mobile support for a box-type substation is shown, comprising a base 1, on which a plurality of weight-reducing grooves 100 are provided, and the weight-reducing grooves 100 are rectangular grooves arranged in a linear array. Side panels 2 are provided at both ends of the base 1, and slide rails 101 are provided on both inner sides of the side panels 2 of the base 1. Slide blocks 3 can be movably connected to both sides of the slide rails 101, and the top of the slide block 3 on the same side is fixedly connected with 4. The bottom of the slide block 3 is fixedly connected with a long rack 18, and the bottom of the long rack 18 is provided with a driving gear 16 for meshing transmission. A crank handle 8 is fixedly connected to the center of the driving gear 16 on one side near the end of the side panel 2, and the middle part of the crank handle 8 is rotatably connected to the rotating hole provided on the base 1, and the other side of the driving gear 16 is fixedly connected with a driving shaft 17 connected to the driving gear 16 at the other end.

[0026] As a further illustration of this example, rotating the crank handle 8 can cause the drive gear 16 fixedly connected thereto to rotate accordingly, and the drive gear 16 on the other side rotates accordingly driven by the drive shaft 17. At the same time, the long rack 18 meshing with the drive gear 16 moves, driving the top slider 3 and the mounting plate 9 fixedly connected to the top of the slider 3 to move back and forth along the slide rail 101.

[0027] A gripping device is fixedly connected to one side of the base 1. The gripping device includes a mounting plate 9 and a hinge rod 11. Two mounting plates 9 are fixed to the two side plates 2 of the base 1 respectively. A hinge shaft is fixedly connected to the mounting plate 9. A stopper 10 is fixedly connected to one side of the hinge shaft on the mounting plate 9. The stopper 10 is in the shape of a right-angled trapezoid. The hinge shaft is rotatably connected to one end of the hinge rod 11. A fixed shaft 13 is fixedly connected to the middle of the hinge rod 11. The fixed shaft 13 cooperates with a fixed groove 14 provided on the side of the side plate 2. An arc-shaped snap-fit ​​block 15 is provided at the bottom of the fixed groove 14. A gripping shaft 12 is fixedly connected to the other end of the hinge rod 11. The gripping shaft 12 is provided with an anti-slip pattern that can increase friction.

[0028] As a further illustration of this example, by rotating the gripping shaft 12 inward, the fixed shaft 13 in the middle of the hinge rod 11 can be engaged with the fixed groove 14, and the locking block 15 at the bottom of the fixed groove 14 will lock and fix the fixed shaft 13, thereby achieving the retraction of the gripping device.

[0029] Four support seats 5 are fixedly connected at the four corners of the bottom of the base 1, and support feet 6 are fixedly connected to the bottom of the support seats 5. A retractable moving device is fixedly connected to the inner side of the support seats 5. The moving device includes a first connecting rod 21, a second connecting rod 19, a wheel frame 20, and a moving wheel 7. One end of the second connecting rod 19 is hinged to the support seat 5, and the other end of the second connecting rod 19 is hinged to the top of the wheel frame 20. The middle part of the wheel frame 20 is hinged to one end of the first connecting rod 21 near the second connecting rod 19, and the other end of the first connecting rod 21 is hinged to the support seat 5. The hinges of the first connecting rod 21 and the support seat 5 and the hinges of the second connecting rod 19 and the support seat 5 are respectively located on both sides of the wheel frame 20, and the bottom of the wheel frame 20 is rotatably connected to the moving wheel 7.

[0030] As a further explanation of this example, the first link 21 and the second link 19 are initially in a folded state. The support base 5 is slightly lifted, and then the first link 21 and the second link 19 are rotated outward together. When the wheel frame 20 is in a vertical state, the first link 21 and the second link 19 are at an angle, supporting the moving wheel 7 on the ground.

[0031] The working principle and use process of the utility model are as follows: Turn the crank handle 8 to move the clamping plates 4 on both sides to the two ends, and then place the substation on the base 1. Only one substation can be placed, or two main and auxiliary substations can be placed. After placement, turn the crank handle 8 in the opposite direction to move the clamping plates 4 on both sides to a position close to the side wall of the substation to fix the substation. When it is necessary to move, open the bottom moving wheel 7 and the side gripping shaft 12, and then pull the gripping shaft 12 to move the device. After the movement is completed, retract the two back to their original positions.

[0032] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above implementation measures. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
