At present, in the development process of oilfield water injection, a plunger type high-pressure water injection pump is a common equipment type. The power transmission between the pump motor and the pump body of the machine is carried out through the belt. Due to the long-term operation of the apparatus, the belt tension is reduced, and loosening, wear breakage and aging phenomena occur. When the belt wears out, breaks or ages, the belt needs to be replaced. However, due to the difficulty in the structure and operation of the current motor sliding rail, the adjustment of the first belt pulley of the motor and the second belt pulley of the water injection pump in a four-point and one-line manner is time-consuming and labor-consuming, and meanwhile, the accuracy is relatively poor, so that the belt is fast in abrasion and easy to damage, the belt is required to be frequently adjusted or replaced, the material waste is caused, and the labor intensity of workers is increased.
In the related art, when adjusting the motor position, an operator adjusts the displacement of the motor in the axial direction by using a crow bar, and after the adjustment is completed, the motor is fixed by tightening a motor fastening bolt. However, the operator utilizes the displacement of crow bar adjustment motor along axial direction, and the adjustment process is not only wasted time and energy, and the adjustment precision is difficult to master moreover, can't realize fine adjustment for belt wearing and tearing are fast, and are fragile.
In order to solve the technical problems in the related art, an embodiment of the present invention provides a motor position adjusting device 1, and a schematic structural diagram thereof is shown in fig. 1.

Similarly, the number of second threaded through holes 1321 may also be different from the number of second bolts 12.
In adjusting the motor position, the motor position adjusting device 1 provided in the embodiment of the present invention needs to be placed on the slide rail 3 for the motor 2 to move, and two identical motor position adjusting devices 1 provided in the embodiment of the present invention, namely, the first motor position adjusting device 1 and the second motor position adjusting device 1, need to be used.

The fixing portion 133 of the bracket 13 of the first motor position adjusting device 1 is lifted up, and after moving along the clamping groove 31 of the slide rail 3 to the side of the first fixing member 21 close to the belt 5, the fixing portion 133 is pressed down to fix the first motor position adjusting device 1 on the slide rail 3.
In step 403, the adjusting device 1 of the second motor position is moved along the clamping groove 31 of the sliding rail 3 to the side of the second fixing piece 22 of the motor 2 away from the belt 5.
Wherein the structure of the second motor position adjusting device 1 is as described in the previous embodiments.
The fixing portion 133 of the bracket 13 of the second motor position adjusting device 1 is lifted up, and after moving along the clamping groove 31 of the slide rail 3 to a side of the second fixing member 22 away from the belt 5, the fixing portion 133 is pressed down to fix the second motor position adjusting device 1 on the slide rail 3.
Step 404, adjusting the second bolt 12 in the first motor position adjusting device 1 and the second bolt 12 in the second motor position adjusting device 1 until the belt 5 is tightened.
Wherein the tensioning force of the belt 5 can be increased step by rotating the second bolt 12 in the first motor position adjusting device 1 and the second bolt 12 in the second motor position adjusting device 1 in the clockwise direction until the belt 5 is tightened, so as to meet the installation requirement in the radial direction.
Step 405, the first bolt 11 in the first motor position adjusting device 1 and the first bolt 11 in the second motor position adjusting device 1 are adjusted such that the side surfaces of the first pulley 23 of the motor 2 and the second pulley 41 of the water injection pump 4 on the same side of the belt 5 are on the same plane.
Wherein, referring to fig. 2, it is possible to measure whether there is a gap between the guiding rule 9 and the first pulley 23 and the second pulley 41 by placing the guiding rule 9 at the outer end faces of the first pulley 23 of the motor and the second pulley 41 of the plunger pump 4. If no gap exists, the requirement of four points and one line is met; if a gap exists, the axial position of the motor 2 needs to be adjusted according to the actual situation of the site by the first bolt 11 in the adjusting device 1 for adjusting the position of the first motor and the first bolt 11 in the adjusting device 1 for adjusting the position of the second motor so as to meet the requirement of four points and one line.
When it is determined that the requirement of "four-point one-line" is satisfied, a plurality of first fastening bolts 24 are sequentially screwed, and the fixation of the position of the motor 2 is achieved.
Finally, the belt shield 7 is prevented from being positioned at the corresponding position of the base 6, so that the belt shield 7 is positioned above the belt 5; the plurality of second fastening bolts 71 are tightened using a wrench, the protection frame 8 is mounted, and the plurality of third fastening bolts 81 are tightened using a wrench, thereby completing the operation.
The motor position adjusting method provided by the embodiment of the invention can be used for quickly adjusting the motor position, improving the adjustment precision of the motor 2 in the radial direction and the axial direction, enabling the motor to meet the installation technical requirement, prolonging the service life of the belt 5, reducing the working strength of operators, improving the maintenance efficiency of equipment, ensuring the normal operation of the equipment and ensuring the safe production.
In the present invention, the terms "first" and "second" and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The term "plurality" refers to two or more, unless explicitly defined otherwise.
