With the continuous advancement of smart grid construction, there are more and more intelligent transformation projects in substations, and the replacement of high-voltage switchgear in the switch room is one of the main tasks of the intelligent transformation projects in substations. Due to the large size and weight of the high-voltage switchgear, and the limited space in the general switch room, lifting equipment such as forklifts and cranes cannot enter the room for operation, so it is difficult to carry, move, and accurately position, and the replacement process requires a lot of time and manpower. At present, for the handling, movement, and accurate positioning of the high-voltage switchgear in the switch room, the usual method is: place the high-voltage switchgear on three to four rollers, push and adjust it to the position by manpower, and then pull out the rollers. bar. The disadvantages of this method are: time-consuming, labor-intensive, inconvenient operation, high labor intensity, and low efficiency. In the process of moving, although there is a special person to command and monitor, it is often caused by human error in the operation of the high-voltage switchgear cabinet. The occurrence of damage phenomena such as collision, vibration, scratches, paint falling, and deformation of the inner rail of the high-voltage switchgear will bury hidden dangers for the safe and stable operation of the new high-voltage switchgear in the future, and there is also a risk of staff being crushed or crushed. risk. In order to overcome the deficiencies of the above technologies, some jacks are used to move the high-voltage switch cabinet from one side of the high-voltage switch cabinet with the wall as a fixed object, so that the high-voltage switch cabinet can be moved in translation. And heavy, jack top power is big, so be easy to damage high-voltage switchgear; The 2nd, be subjected to the restriction of jack telescopic distance, need transposition several times just can reach the moving distance, use still inconvenient. It can be known by retrieval that there is no report on lifting and translating the high-voltage switchgear at present.

Contents of the invention

The purpose of this utility model is to provide a device that is not only simple in structure, low in production cost, and easy to operate, but also enables the high-voltage switchgear to rise and move in place, saves manpower, reduces the labor intensity of operators, and improves labor efficiency. The damage of the high-voltage switchgear, and the operation is safe, and the high-voltage switchgear lifting auxiliary positioning device is convenient for application in the switchgear.

In order to achieve the above purpose, the technical solution adopted by the utility model is: the high-voltage switchgear lifting auxiliary positioning device includes a bottom plate and rollers. There are four rollers, which are respectively installed on the four corners of the bottom wall of the bottom plate. It is characterized in that: a fixed support frame is arranged on the upper part of the bottom plate, a fixed support platform is arranged on the upper part of the fixed support frame, a hydraulic cylinder is arranged in the middle of the support platform, the base of the hydraulic cylinder is welded and fixed vertically to the support platform, and the piston of the hydraulic cylinder The top of the rod is welded and fixed vertically to the top plate.

The utility model is also implemented through the following measures: the four corners of the support platform are all welded and fixed to the upper vertical sleeve, and a guide sliding column is arranged in the vertical sleeve, and the upper end of the guiding sliding column is welded and fixed on the bottom wall of the top plate. corner.

The two rollers at the rear end are installed on the rotating splint to make it have a universal function.

The bottom end of the hydraulic cylinder is provided with four symmetrical angle steels for a week, the height of the angle steels is 4cm, and the angle steels and the support platform are welded and fixed, so that the hydraulic cylinder can be stably fixed.

The beneficial effects of the utility model are: not only the structure is simple, the production cost is low, the operation is easy, but also the manpower is saved, the labor intensity of the operator is reduced, and the labor efficiency is improved. It will not cause damage to the high-voltage switchgear, and the operation is safe. Used for moving high-voltage switchgear in the switch room.

Detailed ways

Make the utility model with reference to Fig. 1, Fig. 2. The high-voltage switch cabinet lifting auxiliary positioning device includes a bottom plate 1 and a roller 2. There are four rollers 2, which are installed on the four corners of the bottom wall of the bottom plate 1 respectively. The support frame 3 has a fixed support platform 4 on the upper part of the fixed support frame 3, and a hydraulic cylinder 5 is arranged in the middle of the support platform 4. The base of the hydraulic cylinder 5 is welded and fixed vertically to the support platform 4, and the top end of the piston rod of the hydraulic cylinder 5 It is welded and fixed vertically with the top plate 6. When the hydraulic cylinder is filled with liquid, the piston rod of the hydraulic cylinder 5 is stretched to lift the top plate 6. When the hydraulic cylinder is back to work, the piston rod of the hydraulic cylinder 5 shrinks, and the top plate 6 is lowered. .

As an improvement of the present utility model: the four corners of the support platform 4 are welded and fixed to the upper vertical sleeve 7, and the vertical sleeve 7 is provided with a guide strut 8, and the upper end of the guide strut 8 is welded and fixed on the top plate 6 corners of the bottom wall, like this, can be kept vertical and not deflected during the lifting process of the piston rod of the hydraulic cylinder 5.

The two rollers 2 at the rear end are installed on the rotating splint 9, so that it has a universal function, which can achieve the purpose of convenient transportation and convenient steering during use.
