Description

Technical Field

[0001] This utility model relates to the field of coal mine maintenance technology, and in particular to a rotatable base. Background Technology

[0002] In order to eliminate problems that exist in long-term operation, ensure the normal operation of the equipment and extend its service life, it is necessary to regularly inspect the 30kW water pump. When inspecting the 30kW water pump, the burnt stator needs to be rewound. After the lower slot is wound, the side slot (upper slot) needs to be wound until all the winding is completed.

[0003] The existing operating procedure requires manual rotation and movement of the stator multiple times. This operation is labor-intensive and time-consuming, and may also cause injury to workers by pressing on their body parts. It is not very safe, and the winding efficiency is low. It takes a long time to repair a 30kW water pump.

[0004] Therefore, to address the issues of low safety and maintenance efficiency caused by repeated manual flipping and moving, a rotatable base can be designed. Utility Model Content

[0005] To overcome the problems of low safety and maintenance efficiency caused by repeated manual flipping and moving.

[0006] The technical solution of this utility model is as follows: a rotatable base, including front and rear channel steels and left and right channel steels; it also includes a lateral adjustment component and a locking component; a middle round steel and left and right symmetrically distributed channel steels are fixedly connected between the front and rear channel steels and another front and rear channel steel; a symmetrically distributed middle bearing is installed on the outer side of the middle round steel; a symmetrically distributed lateral adjustment component is installed on the upper end of the left and right channel steels; a front and rear locking seat that moves laterally is installed on the inner side of the lateral adjustment component; a middle locking seat is engaged between the two front and rear locking seats; a symmetrically distributed support column is fixedly connected to the upper end of the middle locking seat; left and right round steels are fixedly connected to the upper ends of the two support columns; left and right symmetrically distributed bearings are installed on the outer side of the left and right round steels; a locking component for fixing the middle locking seat is installed on the upper end of the front and rear locking seats; the lateral adjustment component includes side plates; a threaded column is fixedly connected between the two side plates; an adjustment block is movably connected to the outer side of the threaded column; the adjustment block is fixedly connected to the front and rear locking seats.

[0007] Preferably, the front and rear channel steels and the left and right channel steels are placed on a stable ground. When overhauling the stator of a 30kW water pump, the intermediate retainer is moved left and right according to the diameter of the stator, and then inserted into the appropriate position between the front and rear retainers. The position of the adjusting block between the side plates is adjusted. The adjusting block slides on the outside of the threaded column, driving the front and rear retainers to move left and right. The intermediate retainer, support column and left and right round steels move synchronously and stop at the appropriate position. The stator is then placed horizontally on the left and right bearings on the outside of the left and right round steels. At the same time, the lower end of the stator is in contact with the intermediate bearing on the outside of the intermediate round steel. After winding the lower channel line, the stator is rotated so that the upper and lower channels are repositioned in place, and the side channel lines can be wound directly.

[0008] Preferably, the front and rear channel steels and the left and right channel steels are of the same specification, all of which are No. 6 channel steels, with a length of 280mm and a width of 60mm.

[0009] Preferably, the front and rear ends of the middle card holder are provided with equally spaced serrated protrusions; the inner sides of the front and rear card holders are provided with grooves that match the serrated protrusions at the front and rear ends of the middle card holder.

[0010] Preferably, the diameter of the middle round steel and the left and right round steel are both 20mm; the middle bearing and the left and right bearings are of the same specification.

[0011] Preferably, the threaded connection on the outer side of the threaded column has adjusting nuts that are symmetrically distributed on the left and right sides of the front and rear retaining seats.

[0012] Preferably, the locking assembly includes a cover plate and a lower insert; the cover plate is rotatably connected to the front and rear card seats via a hinge; an upper insert is fixedly connected to the outside of the cover plate; insert rods are inserted into the upper and lower inserts; and the lower insert is fixedly connected to the left and right channel steels.

[0013] The beneficial effects of this utility model are as follows: The overall structure is simple. The stator is placed on the base bearing, and the bearing characteristics are used to change sliding friction into rolling friction, thereby reducing frictional resistance. This makes it easier to rotate and move the stator, and it is less likely to cause injury to workers. After winding the lower groove line, the stator is rotated to adjust the position of the upper and lower grooves in place. The stator can be directly wound around the side groove (upper groove line). This method reduces the steps of manually handling and rotating the stator, saving manpower and time. It is safe and efficient. It can save 2 hours when overhauling a 30kw water pump, greatly improving the efficiency of water pump maintenance, saving manpower, and improving the utilization of working hours. It is also applicable to stators of different specifications, making it more versatile. Attached Figure Description

[0021] Please see Figure 1 and Figure 4In this embodiment, the front and rear channel steels 1 and the left and right channel steels 2 are of the same specification, all of which are No. 6 channel steel. The length of the front and rear channel steels 1 and the left and right channel steels 2 is 280mm and the width is 60mm. The front and rear ends of the intermediate retainer 7 are provided with equidistant serrated protrusions. The inner side of the front and rear retainers 6 is provided with grooves that match the serrated protrusions at the front and rear ends of the intermediate retainer 7. By engaging the serrated protrusions with the grooves at different positions, the position of the intermediate retainer 7 is adjusted so that it can better fit the stator. The diameter of the intermediate round steel 3 and the left and right round steels 9 is 20mm. The intermediate bearing 4 and the left and right bearings 10 are of the same specification. The intermediate bearing 4 and the left and right bearings 10 are used to change the sliding friction into rolling friction, reduce the friction force, and save manpower.

[0022] Please see Figure 2-Figure 3 In this embodiment, the threaded post 502 is threadedly connected to adjusting nuts 504 that are symmetrically distributed on the left and right sides of the front and rear card seats 6; the locking assembly includes a cover plate 111 and a lower insert 112; the cover plate 111 is rotatably connected to the front and rear card seats 6 via a hinge 113; an upper insert 114 is fixedly connected to the outside of the cover plate 111; insert rods 115 are inserted into the upper insert 114 and the lower insert 112; the lower insert 112 is fixedly connected to the left and right channel steels 2, and the cover plate 111 is fixed by the insert rods 115, thereby preventing the intermediate card seat 7 from sliding out of the front and rear card seats 6.

[0023] When working, place the front and rear channel steel 1 and the left and right channel steel 2 on a stable ground. When overhauling the stator of the 30kW water pump, pull out the insert rod 115 inside the upper insert 114 and the lower insert 112. Open the cover plate 111 through the hinge 113.

It also reduces the steps of manually handling the rotating stator, saving manpower and time. It is safe and efficient. Overhauling a 30kW water pump can save 2 hours, greatly improving the efficiency of water pump maintenance, saving manpower, and increasing the utilization of working hours. Furthermore, it is applicable to stators of different specifications, making it more versatile and solving the problems of low safety and maintenance efficiency caused by repeated manual turning and moving.
