At present, in the oilfield water injection development process, a plunger type high-pressure water injection pump is a common equipment type. The power transmission between the motor and the pump body of the type of the motor pump is carried out through the belt. Due to the long-time operation of the equipment, the tension of the belt is reduced, and the phenomena of looseness, abrasion, breakage and aging can occur. When the belt wears out, breaks, or ages, the belt needs to be replaced. But because the structure of present motor slide rail and the degree of difficulty in the aspect of the operation, the first belt pulley of motor and the adjustment of the second belt pulley "four one line" of water injection pump are wasted time and energy, and the accuracy is still comparatively poor simultaneously, and the influence that so produces makes the belt wearing and tearing fast, and fragile needs frequently to carry out the adjustment or the change of belt, has caused the material waste and has increased workman's intensity of labour.
In the related art, when adjusting the position of the motor, an operator adjusts the displacement of the motor in the axial direction using a pry bar, and after the adjustment is completed, the motor is fixed by tightening a motor fastening bolt. However, the operator adjusts the displacement of the motor along the axial direction by using the crow bar, the adjustment process is time-consuming and labor-consuming, the adjustment precision is difficult to control, fine adjustment cannot be realized, and the belt is fast in abrasion and easy to damage.
In order to solve the technical problems in the related art, an embodiment of the present invention provides an adjusting device 1 for adjusting a position of a motor, which is schematically shown in fig. 1.
Referring to fig. 1, the apparatus includes at least one first bolt 11, at least one second bolt 12, and a bracket 13.
Wherein, the bracket 13 comprises a first adjusting part 131, a second adjusting part 132 and a fixing part 133, wherein one end of the first adjusting part 131 is connected with one end of the second adjusting part 132, and the extending direction of the first adjusting part 131 is perpendicular to the extending direction of the second adjusting part 132, i.e. a right angle is formed between the first adjusting part 131 and the second adjusting part 132; the fixing portion 133 is located at one side of the other end of the second adjusting portion 132, and is connected to the second adjusting portion 132, and the fixing portion 133 can provide a fulcrum for the first adjusting portion 131 and the second adjusting portion 132, thereby fixing the entire bracket 13.
The first adjusting portion 131 has at least one first threaded through hole 1311, and at least one first bolt 11 is movably disposed on the first adjusting portion 131 through the first threaded through hole 1311 in a one-to-one correspondence for adjusting an axial position of the motor 2.
The second adjusting portion 132 has at least one second threaded through hole 1321, and at least one second bolt 12 is movably disposed on the second adjusting portion 132 through the second threaded through hole 1321 in a one-to-one correspondence, for adjusting a radial position of the motor 2.
It is understood that the number of first threaded through holes 1311 may be different from the number of first bolts 11, for example, the number of first threaded through holes 1311 may be greater than the number of first bolts 11. Similarly, the number of the second threaded through holes 1321 may also be different from the number of the second bolts 12.
When adjusting the motor position, the motor position adjusting device 1 provided by the embodiment of the present invention needs to be placed on the slide rail 3 for moving the motor 2, and two identical motor position adjusting devices 1 provided by the embodiment of the present invention, that is, the first motor position adjusting device 1 and the second motor position adjusting device 1, need to be used.
The working principle of the adjusting device for the position of the motor provided by the embodiment of the invention is as follows:
in the case that the motor 2 has moved to the preset position, the radial adjustment of the position of the motor 1 is achieved by moving the adjusting device 1 of the first motor position to the side of the first fixing member 21 of the motor 2 close to the belt 5, moving the adjusting device 1 of the second motor position to the side of the second fixing member 22 of the motor 2 far from the belt 5, and adjusting the second bolts 12 in the adjusting device 1 of the first motor position and the adjusting device 1 of the second motor position, respectively, until the belt is tightened; and then the first bolt 11 in the adjusting device 1 for adjusting the position of the first motor and the adjusting device 1 for adjusting the position of the second motor respectively realizes the axial adjustment of the position of the motor 2, so that the side surfaces of the first belt pulley 23 of the motor 2 and the second belt pulley 41 of the water injection pump 4, which are positioned on the same side of the belt 5, are positioned on the same plane, that is, the requirement of 'four points and one line' is met, and the adjustment of the position of the motor 2 is realized.
Therefore, when the position of the motor 2 is adjusted in the radial direction and the axial direction by using the adjusting device 1 for adjusting the position of the motor provided by the embodiment of the invention, the accuracy of the adjustment in the radial direction and the axial direction can be controlled by screwing the first bolt 11 and the second bolt 12 respectively, so that fine adjustment can be realized, the installation accuracy is improved, and the service life of the belt is prolonged. Meanwhile, compared with an adjusting mode of adjusting the displacement of the motor along the axial direction by using a crow bar in the related art, the operation is more convenient and quicker, the labor intensity of workers is reduced, the equipment maintenance efficiency is improved, and the safety production is ensured.
The following further describes the structure of the adjusting device for the motor position provided by the embodiment of the present invention:
in one possible design, the first adjusting portion 131, the second adjusting portion 132 and the fixing portion 133 constituting the bracket 13 are integrally formed, thereby facilitating the manufacturing process.

So configured, the first bolt 11 can be selectively located in the three first threaded through holes 1311, so as to achieve axial adjustment of the position of the motor 2.
It should be noted that, because the models of the motors 2 are different, and the length, the width, and the height of the fixing members of the motors 2 of different models are different, the number and the positions of the first threaded through holes 1131 to be used can be determined according to the motors 2 of different models.
For example, referring to fig. 1, the number of the first bolts 11 is three, and three first bolts 11 are located in the three first threaded through holes 1311 in a one-to-one correspondence.
In one possible design, referring to fig. 1, the number of the second threaded through holes 1321 may be two, and the two second threaded through holes 1321 are sequentially disposed on the second adjustment part 132 in the extending direction of the second adjustment part 132.
So configured, the second bolt 12 can be selectively positioned in the two first threaded through holes 1311, thereby achieving radial adjustment of the position of the motor 2.
When the second bolt 12 is provided in each of the two first tapped through holes 1311, which is an improvement over the existing radial adjustment, the stability of the adjustment can be increased by providing two second bolts 12.
In a possible design, referring to fig. 1, a side of the fixing portion 133 facing the motor 2 has an inclined surface, and an area of a cross section of the fixing portion 133 gradually increases from a side close to the second adjusting portion 132 to a side far from the second adjusting portion 132, so that the fixing portion 133 can enter the slot 31 of the slide rail 3, and can be fixed at a corresponding position by being matched with the slide rail 3, so as to provide a firm supporting point for the first bolt 11 and the second bolt 12, and thus the motor 2 can be displaced.
In one possible design, each first bolt 11 and each second bolt 12 is a cylinder with an external thread.
In one possible design, referring to fig. 1, each first bolt 11 and each second bolt 12 has a nut 14, so that an operator can adjust the position of the first bolt 11 or the second bolt 12 by operating the nut 14.
