Description

Technical Field

[0001] The invention relates to the technical field of electric motors, and in particular to a motor base structure. Background Art

[0002] In order to improve the recovery rate of crude oil, high-pressure water injection pumps are used in the water injection system of oil field development. Among them, high-pressure water injection pumps are usually high-pressure reciprocating plunger pumps. Since the motor and pump of the high-pressure reciprocating plunger pump are driven by belts, the belts need to be replaced after the equipment has been running for a certain period of time to maintain the stable operation of the equipment. When replacing the belt, it is necessary to move a heavy motor.

[0003] At present, the method for replacing the belt of a high-pressure water injection pump is generally to first loosen the multiple screws on the high-pressure reciprocating piston pump so that the motor base can be moved on the pump base, and then use a crowbar and a sledgehammer to adjust the relative position of the motor and the pump, and then replace the belt.

[0004] In the process of implementing the present invention, the inventors found that the related technology has at least the following problems:

[0005] Since the method of adjusting the tightness of the screw cannot separate the contact surface between the motor base and the pump base, the contact surface is easily damaged when the motor base is moved; at the same time, since the operable space where the multiple fixing bolts of the motor base and the pump base are located is small, it is not conducive to disassembly and installation; and the method of moving the relative position of the motor by using a crowbar and a sledgehammer can easily cause deformation of the components and cause damage, and it is very laborious when operated manually.

DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] Before further describing the implementation methods of the present application in detail, the orientation nouns involved in the embodiments of the present application are based on the orientation shown in the figure and are only used to clearly describe the motor base structure of the embodiments of the present application, and do not have the meaning of limiting the scope of protection of the present application.

[0056] The implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0057] The present application embodiment provides a motor base structure, see Figure 1 and Figure 2 The structure includes a square tube shell 1, a first jack 6, an adjustment plate 3 and a fixing seat 5.

[0058] A universal ball 61 is provided on the lifting surface of the first jack 6 .

[0059] The square tube shell 1 is placed on the fixing seat 5, a first through hole 103 is opened on the lower plate 102 of the square tube shell 1, the base end of the first jack 6 supports the upper plate 101 of the square tube shell 1, and the universal ball 61 passes through the first through hole 103 to support the upper surface of the base of the high-pressure reciprocating plunger pump.

[0060] The adjustment plate 3 is located on the upper side of the upper plate 101 and can move relative to the square tube housing 1 . The adjustment plate 3 has a structure suitable for connecting with a motor.

[0061] Combination Figure 1 As shown, the working principle of the motor base structure provided in the embodiment of the present application is as follows:

[0062] Place the square tube housing 1 on the pump base and under the motor, and use the first jack 6 to lift up the motor and the square tube housing 1 supporting the motor, so that the motor is first separated from the pump base, and then the motor is moved closer to the pump body, so that the belt connecting the pump body and the motor can be replaced.

[0063] To summarize, by utilizing the motor base structure provided in the embodiment of the present application, when replacing the belt of a high-pressure reciprocating plunger pump, the contact surface between the motor and the pump base can be separated first, and then the motor can be moved close to the pump body, so that the belt can be replaced. This not only avoids wear and tear caused by movement when the motor base contacts the pump base, but also makes the operation of moving the motor easier and quicker, thereby improving the efficiency of replacing the belt of the high-pressure reciprocating plunger pump.

[0064] The structure and function of each component unit of the motor base structure provided in this embodiment are described in more detail below.

[0065] The motor base structure is an axisymmetric structure, and the axis of symmetry is perpendicular to the surface of the side plate 105 of the square tube housing 1 .

[0066] See also Figure 1 The square tube shell 1 includes a U-shaped steel and a lower plate 102. The upper plate 101 is the middle plate of the U-shaped steel, the opening side of the U-shaped steel faces downward, and the lower plate 102 is welded to the opening side of the U-shaped steel.

[0067] Optionally, in the motor base structure, two fixing seats 5 are provided, and the two fixing seats 5 are respectively located below the inner sides of both ends of the square tube shell 1, and each fixing seat 5 includes a first fixing plate 501 and a second fixing plate 502 placed up and down.

[0068] The first fixing plate 501 is welded to the lower surface of the lower plate 102 of the square tube housing 1 .

[0069] Alternatively, if Figure 4 As shown, the first end of the first fixing plate 501 is provided with a first mounting hole 5011, and the second end is provided with a second mounting hole 5012; the first end of the second fixing plate 502 is provided with a third mounting hole 5021, and the second end is provided with a fourth mounting hole 5022.

[0070] Among them, see Figure 4 The first mounting hole 5011 and the third mounting hole 5021 are connected by a quick locking pin 9, and the second mounting hole 5012 and the fourth mounting hole 5022 are connected by a bolt 4.

[0071] Optionally, a first portion of the upper surface of the second fixing plate 502 is covered by the first fixing plate 501 , and an uncovered second portion is located outside the first fixing plate 501 .

[0072] It should be noted that the distance between the two first fixing plates 501 is smaller than the width of the inner side of the pump base in the high-pressure reciprocating piston pump, and the two first fixing plates 501 are symmetrically distributed below the inner sides of both ends of the square tube housing 1 .

[0073] It can be understood that when the fixing base 5 is placed, the uncovered second portion of the second fixing plate 502 is placed on the lower surface of the pump base, supporting the pump base; the side surface of the first fixing plate 501 is against the side surface of the pump base. In other words, when the quick locking pin 9 and the bolt 4 are locked, the fixing base 5 is firmly fixed on the pump base, and then the motor base is also fixed on the pump base.

[0074] Alternatively, if Figure 3As shown, a first groove 51 is provided on the lower surface of the first end of each second fixing plate 502, and a second groove 52 is provided on the lower surface of the second end. The pin cap of the quick locking pin 9 abuts against the bottom of the first groove 51, and the nut of the bolt 4 abuts against the bottom of the second groove 52.

[0075] It is understandable that the width of the first groove 51 matches the pin cap of the quick locking pin 9, and the width of the second groove 52 matches the nut of the bolt 4. Therefore, the two grooves can play a limiting role, avoiding the instability of the entire motor base structure caused by the shaking of the quick locking pin 9 and the bolt 4.

[0076] Alternatively, if Figure 1 As shown, two baffles 7 are respectively provided on the inner sides of both ends of the square tube housing 1 , and each baffle 7 is respectively connected to the inner sides of the two side plates 105 of the square tube housing 1 .

[0077] Optionally, each baffle 7 is provided with a mounting hole, such as Figure 4 As shown, they are the fifth mounting hole 701 and the sixth mounting hole 702, respectively. The first side plate 1051 and the second side plate 1052 of the square tube housing 1 are both provided with positioning holes corresponding to the above-mentioned mounting holes, such as Figure 1 As shown, they are the third positioning hole 106 and the fourth positioning hole 107. The fifth mounting hole 701 corresponds to the third positioning hole 106, and the sixth mounting hole 702 corresponds to the fourth positioning hole 107, and they are fixedly connected by bolts.

[0078] It should be noted that if Figure 1 As shown, two baffles 7 are respectively arranged at both ends of the square tube housing 1, for example, a first baffle 71 and a second baffle 72 are arranged on the left side of the square tube housing 1. Since a slot is formed by the distance between the first baffle 71 and the second baffle 72, when the first jack 6 is placed in the square tube housing 1, it can limit the first jack 6, thereby avoiding the instability of the entire motor base structure caused by the instability of the first jack 6.

[0079] It should be noted that when the first jack 6 is placed in the square tube, each baffle is fixedly connected to the side plate 105 of the square tube housing 1 by bolts. It is understandable that the width of the base of different types of jacks is different. In order to make the baffle reach the purpose of limiting the first jack 6, it is necessary to select baffles of different thicknesses to form slots of different widths; when the overall adjustment of the motor is completed, the baffle can be removed, and then the positioning bolts are passed through the two opposite positioning holes on the side plate 105 of the square tube housing 1, and at the same time through the corresponding positioning holes on the base of the high-pressure reciprocating piston pump, and after tightening, the motor base structure is fixed.

[0080] It is understandable that, since the motor will generate severe vibrations during normal operation, after replacing the belt, the motor base can be stably mounted on the base of the high-pressure reciprocating piston pump by fixing with positioning bolts, so that the entire device remains stable.

[0081] Alternatively, if Figure 1 As shown, the upper plate 101 of the square tube housing 1 is provided with an adjustment groove 2 , and the adjustment groove 2 extends along the length direction of the square tube housing 1 ; the adjustment plate 3 is located above the adjustment groove 2 .

[0082] It should be noted that the width of the adjustment groove 2 is not less than the diameter of the universal ball 61 .

[0083] Optionally, two positioning holes 8 are provided on the adjustment plate 3, each positioning hole 8 corresponds to an anchor bolt hole of the motor one by one, and the positioning hole 8 and the anchor bolt hole of the motor are connected together by bolts.

[0084] Optionally, the motor base structure also includes a second jack, the structure of the second jack is the same as the first jack 6, the side panel 105 of the square tube shell 1 is provided with a second through hole 104, the second jack enters the square tube through the second through hole 104, the base end of the second jack is against the lower plate 102, and the universal ball of the second jack is against the adjusting plate 3 to lift the adjusting plate 3.

[0085] It should be noted that the second through hole 104 is to allow the second jack to enter the square tube for operation. Therefore, a through hole can be provided on each of the two side plates of the square tube housing 1, i.e., the first side plate 1051 and the second side plate 1052; or two through holes can be provided on only the first side plate 1051 at the same time, for example Figure 1 The first sub-via 1041 and the second sub-via 1042 are shown.

[0086] It should be noted that, because the purpose of placing the second jack in the square tube housing 1 is to lift up the adjustment plate to facilitate moving the motor, the two through holes provided on the side plate of the square tube housing 1 are both located below the adjustment plate 3 .

[0087] It can be understood that, because the universal ball 61 is a sphere and can rotate arbitrarily, it is easier and more labor-saving to move the motor.

[0088] Optionally, the first jack 6 and the second jack are ultra-thin hydraulic jacks.

[0089] It should be noted that there are multiple ways to set the universal ball 61. One is to connect the originally independent jack and universal ball bearing by bolts to form an integrated structure; one is to weld the originally independent jack and universal ball bearing to form an integrated structure; the other is to directly set the top of the jack as a universal ball. Any of the above ways of setting the universal ball can be applied to the motor base structure of the embodiment of the present application.

[0090] Optionally, the upper plate 101 of the square tube housing 1 is provided with an adjustment slot 2 , the adjustment plate 3 is located above the adjustment slot 2 , and the width of the adjustment slot 2 is greater than the diameter of the universal ball 61 .

[0091] It can be understood that, since the width of the adjustment slot 2 is greater than the diameter of the universal ball 61, when the second jack is placed in the square tube housing 1 and the second jack is started, the universal ball on the second jack can pass through the adjustment slot 2, thereby lifting the adjustment plate 3 carrying the motor.

[0092] The working principle of the motor base provided in the embodiment of the present application is:

[0093] Two identical motor base structures provided by the embodiments of the present application are placed below the motor of the high-pressure reciprocating piston pump and in parallel along the axial direction of the motor.

[0094] It should be noted that when the two motor bases are placed, the quick locking pins 9 are placed relative to each other, and the quick locking pins 9 and the bolts 4 are placed and not tightened.

[0095] First, the two positioning holes 8 on the adjustment plate 3 in each motor base are respectively connected to the corresponding motor anchor bolt holes by bolts, and then the following operations of moving the motor and replacing the belt on the high-pressure reciprocating piston pump are started:

[0096] The first step: place four first jacks 6 of the same structure in the slots at both ends of each square tube shell 1, the base end of each first jack 6 supports the upper plate 101 of the square tube shell 1, and each universal ball 61 faces the lower plate 102 of the square tube shell 1 and is located at the through hole of the lower plate 102.

[0097] Step 2: Start each first jack 6. When the lifting surface of each first jack 6 is raised, the universal ball 61 protrudes from the through hole, and the surface of the universal ball 61 is against the upper surface of the pump base of the high-pressure reciprocating plunger pump. The surface of the pump base will generate a force in the opposite direction to the first jack 6, so that the square tube housing 1 carrying the motor is lifted up, thereby separating the motor from the pump base of the high-pressure reciprocating plunger pump.

[0098] Step 3: After the motor is separated from the pump base, the motor can be easily moved due to the universal ball 61, that is, displacement is generated in a direction perpendicular to the axial direction of the motor, that is, the motor is adjusted to be close to or away from the pump body.

[0099] Step 4: After adjusting to the desired position, remove the loads of the four first jacks 6 so that the motor base contacts the pump base, tighten each quick locking pin 9, tighten each bolt 4, and then replace the belt on the high-pressure reciprocating piston pump.

[0100] It should be noted that the four first jacks 6 of the same structure can be removed first and then replaced for use the next time the motor needs to be moved; or they can be placed in the original position and the next operation of moving the motor can be performed directly in the original position.

[0101] Step 5: After replacing the belt, place the four first jacks 6 of the same structure at both ends of each square tube housing 1 again, repeat the above-mentioned first, second and third steps, adjust the motor to the original working position, unload the load, and tighten each quick locking pin 9 and each bolt 4.

[0102] Step 6: Insert four second jacks of the same structure into the square tube through the second through holes 104 opened on the side plate 105 of the square tube housing 1. At this time, each second jack is located below the adjustment plate 3. The second jacks are placed in the following direction: the base end of each second jack is against the lower plate 102 of the square tube housing 1, the universal ball faces the upper plate 101 of the square tube housing 1, and each universal ball is located below the adjustment slot. At this time, loosen the anchor bolts fixing each motor.

[0103] It should be noted that the second jack may be the first jack 6 that is moved out after unloading.

[0104] Step 7: Start the second jacks. When the lifting surface of each second jack is raised, each universal ball protrudes out and passes through the corresponding adjustment slot 2 to abut against the adjustment plate 3, so that the adjustment plate 3 carrying the motor is lifted up, so that the motor is separated from the square tube housing 1.

[0105] Step 8: After the motor is lifted up, the position of the motor can be easily moved due to the universal ball, that is, displacement is generated along the axial direction of the motor to adjust the position of the motor pulley and the pump pulley.

[0106] Step 9: When the motor pulley is aligned with the pump pulley, remove the load of the second jack and tighten the motor anchor bolts.

[0107] It can be understood that aligning the pulley of the motor with the pulley of the pump can avoid wear of the belt during operation due to misalignment, thereby reducing the service life of the belt.

[0108] Step 10: After the motor is adjusted as a whole and the belt is replaced, insert the positioning bolts into the positioning holes on the motor base at the same time, e.g. Figure 1 The third positioning hole 106 and the fourth positioning hole 107 on the pump base are formed, and the positioning bolts are also inserted into the corresponding positioning holes on the pump base, so that the motor base and the pump base are fixed together.

[0109] It is understandable that the motor will generate huge vibrations during operation. After the positioning bolts are inserted, the motor can be prevented from displacement and movement during operation. This design can ensure the normal operation of the high-pressure reciprocating piston pump equipment.

[0110] It should be noted that the motor base provided in the embodiment of the present application is equivalent to moving the motor in two different directions, adjusting the position of the motor and the pump in the high-pressure reciprocating piston pump, that is, after moving in two different directions, the motor is fixed to a normal working position.

[0111] The above steps are divided into two parts: the first part, that is, the first to fifth steps, is the movement of the motor in the direction perpendicular to the motor axis; the second part, that is, the sixth to tenth steps, is the movement of the motor along the motor axis. The operations of the first and second parts are not in order, nor are the number of operations specified, but only need to adjust the motor to the correct position according to the needs.

[0112] In summary, the embodiment of the present application provides an operation that is easy to move the motor on the motor base structure. Since the first jack 6 and the square tube housing 1 are provided in the motor base structure provided in the embodiment of the present application, and the universal ball 61 is provided on the lifting surface of the first jack 6, when the belt of the high-pressure reciprocating piston pump is replaced, the first jack 6 can be used to lift the motor and the square tube housing 1 connected thereto, so that the motor is separated from the pump base. In other words, the contact surface of the motor and the pump base can be separated first, and then the motor can be easily moved along the axis direction perpendicular to the motor to achieve the purpose of approaching or moving away from the pump. Thus, the belt of the high-pressure reciprocating piston pump can be replaced. In addition, after replacing the belt, the second jack is used to lift the adjustment plate carrying the motor, and the motor is separated from the square tube housing at this time, so that the motor can be easily moved along the direction of the motor axis, and the relative position of the motor pulley and the pump pulley is adjusted. After the surfaces of the two pulleys are flush, the motor base structure is fixed.

[0113] The motor base structure not only avoids wear caused by movement of the motor base when in contact with the pump base, but also makes the operation of moving the motor easier and quicker, thereby improving the efficiency of replacing the belt of the high-pressure reciprocating plunger pump.

[0114] At the same time, the relatively placed quick locking pins 9 make it easy to fix the motor base in a narrow operating space. That is, when fixing and disassembling the motor base and the pump base, it is only necessary to first remove each bolt 4 located on the outside with sufficient operating space, and then tighten the quick locking pin 9 to complete the fixation. This design is not only easy to operate, but also saves time, improves efficiency and reduces costs compared to the fixing method using only bolts.
