Description

Technical Field

[0001] The utility model relates to the technical field of electric pump bearing installation, in particular to a mine flameproof submersible sand discharge electric pump bearing quick installation device. Background Art

[0002] Submersible electric pumps are water pumps in which the pump body impeller and the motor driving the impeller are submerged in water. There are two types of pumps: deep well pumps and surface pumps. The motors used in submersible electric pumps are dry type (the motor is completely sealed), semi-dry type (the stator of the motor is sealed, and the rotor runs in the water), oil-filled type (the motor is filled with oil to prevent moisture from invading the windings) and wet type (the motor is filled with water, and the stator and rotor are running in the water). They are widely used in the mining industry. During the assembly of the electric pump, one of the steps is to install the bearings.

[0003] In the prior art, a hammer is generally used to hammer the bearing into the inner side of the electric pump housing. However, in this method, the electric pump is placed directly on the platform without being limited, which will affect its stability during hammering. In addition, since the force of the hammer cannot be evenly distributed to the bearing, it is easy to tilt, resulting in inaccurate positioning and low overall efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a quick-installation device for the bearing of a flameproof submersible sand-removing electric pump for mining. During use, the quick-installation device can make the hammering force correspond to the bearing more evenly, which not only improves the efficiency of the hammering but also avoids the need for cleaning.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A connecting mechanism is used to connect the rectangular block and the U-shaped bar.

[0008] Preferably, a three-jaw chuck is fixedly connected to the upper end of the base.

[0009] Preferably, a hammer plate is fixedly connected to the upper end of the connecting column.

[0010] Preferably, the connecting mechanism comprises a rectangular block fixedly connected to the lower end of the connecting column, a rectangular groove is formed at the upper end of the U-shaped strip, and the lower end of the rectangular block extends into the rectangular groove.

[0011] Preferably, through openings are provided on the inner walls on both sides of the left and right sides of the rectangular groove, and limiting strips are provided through the two through openings. Limiting grooves are provided on both sides of the left and right sides of the rectangular block, and the opposite sides of the two limiting strips extend into the limiting grooves. The opposite sides of the two limiting strips extend to the outside and are fixedly connected with pulling plates. The opposite sides of the two pulling plates are elastically connected to the U-shaped strips through springs.

[0012] Preferably, L-shaped guide columns are fixedly connected to the left and right sides of the rectangular block, and the vertical ends of the two L-shaped guide columns penetrate the L-shaped mounting plate and are slidably connected to the L-shaped mounting plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] A three-jaw chuck is provided to limit the electric pump housing to ensure stability during installation. In addition, through the setting of the contact ring, the hammering force can be evenly distributed on the bearing by simply hammering the hammering plate, thereby avoiding the bearing from tilting during installation. In addition, the installation efficiency is effectively improved. The overall adaptability of the device is strong and can adapt to different electric pump bearing installations.

[0021] Among them, a three-jaw chuck 3 is fixedly connected to the upper end of the base 1. The three-jaw chuck 3 is a prior art, which can start the effect of limiting different workpieces;

[0022] Wherein, it also includes a connecting mechanism, which is used to connect the rectangular block 7 and the U-shaped strip 8. The connecting mechanism includes a rectangular block 7 fixedly connected to the lower end of the connecting column 5, a rectangular groove 11 is provided at the upper end of the U-shaped strip 8, and the lower end of the rectangular block 7 extends into the rectangular groove 11. The inner walls on the left and right sides of the rectangular groove 11 are provided with through openings, and a limiting strip 12 is provided through the two through openings. Limiting grooves 10 are provided on the left and right sides of the rectangular block 7, and the opposite sides of the two limiting strips 12 extend into the limiting groove 10. The opposite sides of the two limiting strips 12 extend to the outside and are fixedly connected with a pulling plate 13. The opposite sides of the two pulling plates 13 are elastically connected to the U-shaped strip 8 through a spring 14. L-shaped guide columns 4 are fixedly connected to the left and right sides of the rectangular block 7, and the vertical ends of the two L-shaped guide columns 4 penetrate the L-shaped mounting plate 2 and are slidably connected to the L-shaped mounting plate 2.

[0023] In the utility model, when in use, first pull the connecting column 5 upward to a higher height and do not release it, then use the three-jaw chuck 3 to limit the electric pump housing, and then place the bearing on the upper end surface of the electric pump housing. At this time, due to the certain friction between the outer side of the bearing and the inner wall of the electric pump housing, it cannot move downward due to gravity. Then loosen the connecting column 5, let the lower end surface of the contact ring 9 contact the upper end surface of the bearing, and then use a hammer to hammer the hammer plate 6. Through the guiding effect of the connecting column 5 and the two L-shaped guide columns 4, the hammering force will be transmitted to the bearing, and finally the bearing will be directly pressed into the electric pump housing to complete the installation;
