Description

Technical Field

[0001] This application belongs to the field of petrochemical equipment, and in particular relates to an adjustable motor support structure. Background Technology

[0002] In practical applications of petrochemical plants, on-site pump sets are often matched with a motor of fixed rated power and designed with a fixed welded base support structure. Due to differences in the installation dimensions of motors with different power ratings, when a motor needs to be replaced, the original base must be cut, ground, and a new support structure must be welded. This modification not only requires high-precision welding to ensure the levelness of the support surface, but also, in the flammable and explosive petrochemical environment, requires waiting until the plant is shut down due to the prohibition of hot work. This results in long equipment replacement cycles, high maintenance costs, and the risk of affecting the safe operation of the plant due to the inability to adjust the motor in a timely manner. Therefore, it is necessary to solve the above-mentioned technical problems. Utility Model Content

[0003] The purpose of this application is to provide an adjustable motor support structure to solve the technical problem that the motor base cannot be flexibly adjusted in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide an adjustable motor support structure, comprising:

[0005] Base plate;

[0006] Support beams are connected at intervals on the same side of the base plate;

[0007] A top plate is connected to the side of the support beam away from the bottom plate and is spaced apart from the bottom plate;

[0008] A support plate is stacked on the side of the top plate away from the bottom plate and has lugs extending beyond the top plate at both ends. Several support plates are arranged parallel to each other on the same side of the top plate.

[0009] The adjustment assembly includes a first set screw seat connected to the side of the support plate opposite to the top plate, a second set screw seat spaced apart from the first set screw seat and connected to the support plate, and a lifting block connected to the lug. It also includes a first screw, a second screw, and a lifting screw that are axially perpendicular to each other. The first screw is threaded to the first set screw seat and passes through the first set screw seat along its own axial direction. The second screw is threaded to the second set screw seat and passes through the second set screw seat along its own axial direction. The axial directions of the first screw and the second screw are both parallel to the support plate. The lifting screw is threaded to the lifting block and its axial end abuts against the bottom plate.

[0010] Optionally, the first set screw seat and the second set screw seat are respectively disposed at the ends of the support plate.

[0011] Optionally, the adjusting assembly further includes a pin parallel to the lifting screw;

[0012] The pins are distributed radially on both sides of the lifting screw, and the lugs and the lifting block are respectively provided with pin holes for accommodating the pins. The lifting block is detachably connected to the lugs via the pins.

[0013] Optionally, the middle portion of the pin forms a flange;

[0014] The flange gasket is placed between the lifting block and the lug, creating a gap between the lifting block and the lug that facilitates observation of the position of the lifting screw.

[0015] Optionally, the lifting screw includes a threaded portion for threaded connection with the lifting block and a spherical portion for abutting against the base plate;

[0016] The spherical part forms a spherical shape and the lifting screw abuts against the base plate through the arcuate surface of the spherical part.

[0017] Optionally, the lifting screw further includes a hexagonal portion located between the threaded portion and the spherical portion;

[0018] The hexagonal portion forms a hexagonal prism structure coaxial with the threaded portion.

[0019] Optionally, the adjustment assembly further includes multiple pads of different thicknesses;

[0020] The pad is optionally placed between the support plate and the top plate.

[0021] Optionally, the adjustment assembly may further include a plurality of fasteners;

[0022] The support plate and the top plate are provided with corresponding coaxial connecting holes, and the support plate is detachably connected to the top plate by fasteners that can be installed in the connecting holes.

[0023] Optionally, a receiving cavity for accommodating the fastener is formed on the support plate, and the fastener does not extend beyond the receiving cavity in the normal direction of the support plate.

[0024] Optionally, the support plate has a number of mounting holes for connecting the target motor on the side opposite to the top plate.

[0025] The beneficial effects of the adjustable motor support structure provided in this application are as follows: Compared with the prior art, in the adjustable motor support structure provided in this application, since the first screw threaded to the first set screw seat and the second screw threaded to the second set screw seat are axially perpendicular, when the target motor is placed on the side surface of the support plate away from the top plate, the first screw and the second screw can respectively rotate relative to the first set screw seat and the second set screw seat to push the target motor to translate on the support plate; furthermore, since the lifting screw threaded to the lifting block also abuts against the bottom plate and the axes of the lifting bolt, the first screw, and the second screw are perpendicular to each other, when the lifting screw rotates relative to the lifting block, it can drive the lifting block and the lug connected to the lifting block to be lifted in a direction perpendicular to the support plate, so that the target motor placed on the support plate can also be lifted accordingly. Therefore, the adjustable motor support structure provided in this application can flexibly adjust the position of the target motor in space, which is far superior to the prior art.

[0036] Please refer to the following: Figures 1 to 4 The adjustable motor support structure provided in this application embodiment will now be described. This adjustable motor support structure includes a base plate 101, a support beam 102, a top plate 103, a support plate 104, and an adjustment assembly. Wherein:

[0037] Several support beams 102 are connected at intervals on the same side of the base plate 101; a top plate 103 is connected to the support beams 102 on the side away from the base plate 101 and is spaced apart from the base plate 101; support plates 104 are stacked on the side of the top plate 103 away from the base plate 101 and have lugs 105 extending beyond the top plate 103 at both ends; several support plates 104 are arranged parallel to each other on the same side of the top plate 103; the adjustment assembly includes a first set screw seat 106 connected to the side of the support plate 104 away from the top plate 103, and a second set screw seat spaced apart from the first set screw seat 106 and connected to the support plate 104. The support plate 104 includes a lifting block 108 connected to the lug 105 and a first screw 109, a second screw 110, and a lifting screw 111, all axially perpendicular to each other. The first screw 109 is threaded to a first setter seat 106 and passes through it along its own axis. The second screw 110 is threaded to a second setter seat 107 and passes through it along its own axis. The axes of the first screw 109 and the second screw 110 are parallel to the support plate 104. The lifting screw 111 is threaded to the lifting block 108, and one end of it abuts against the base plate 101 along its axial direction. It is understood that in specific implementations of this embodiment, the bottom of the base plate 101 may also be provided with more fixing structures such as fixing seats, which will not be elaborated upon here.

[0038] According to the structure provided in this embodiment, in the adjustable motor support structure provided in this embodiment, since the first screw 109 threaded to the first set screw seat 106 and the second screw 110 threaded to the second set screw seat 107 are axially perpendicular, when the target motor 200 is placed on the side surface of the support plate 104 away from the top plate 103, the first screw 109 and the second screw 110 can respectively abut against the target motor 200 by rotating relative to the first set screw seat 106 and the second set screw seat 107. The target motor 200 moves horizontally on the support plate 104. Since the lifting screw 111, threaded to the lifting block 108, also abuts against the base plate 101, and the axes of the lifting bolt, the first screw 109, and the second screw 110 are perpendicular to each other, when the lifting screw 111 rotates relative to the lifting block 108, it can drive the lifting block 108 and the lug 105 connected to the lifting block 108 to rise in a direction perpendicular to the support plate 104. Thus, the target motor 200 placed on the support plate 104 can also be lifted accordingly. Therefore, the adjustable motor support structure provided in this embodiment can flexibly adjust the position of the target motor 200 in space, achieving coaxiality between the output shaft of the target motor 200 and the input shaft of the target pump unit, which is far superior to existing technologies.

[0039] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4The first setter seat 106 and the second setter seat 107 are respectively disposed at the ends of the support plate 104. In this embodiment, the first setter seat 106 is disposed on the lug 105. According to the structure provided in this embodiment, the first setter seat 106 and the second setter seat 107 disposed at the ends of the support plate 104 can reserve sufficient space in the middle position of the support plate 104 to install the target motor 200, and can also provide more sufficient adjustment space for the target motor 200. This is beneficial to further improve the flexible adjustment effect of the adjustable motor support structure in this embodiment.

[0040] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The adjustment assembly also includes a pin 112 parallel to the lifting screw 111. The pin 112 is radially distributed on both sides of the lifting screw 111. The lug 105 and the lifting block 108 are respectively provided with pin holes 113 for accommodating the pin 112. The lifting block 108 is detachably connected to the lug 105 via the pin 112. According to the structure provided in this embodiment, the pins 112 distributed on both sides of the lifting screw 111 can not only connect the lifting block 108 to the lug 105, but also prevent the lifting block 108 from rotating around the axial direction of the lifting screw 111 during the adjustment process, ensuring a stable and reliable adjustment process. This is beneficial to further improve the flexible adjustment effect of the adjustable motor support structure in this embodiment.

[0041] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The middle portion of the pin 112 forms a flange 114; the flange 114 is placed between the lifting block 108 and the lug 105, creating a gap between the lifting block 108 and the lug 105 that facilitates observation of the position of the lifting screw 111. According to the structure provided in this embodiment, the gap formed between the lifting block 108 and the lug 105 by the flange 114 allows the operator to easily observe the position of the lifting screw 111, effectively preventing the lifting block 108 and the lug 105 from separating, thereby further improving the flexible adjustment effect of the adjustable motor support structure in this embodiment.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The lifting screw 111 includes a threaded portion 115 for threaded connection with the lifting block 108 and a spherical portion 116 for abutting against the base plate 101. The spherical portion 116 is spherically shaped, and the lifting screw 111 abuts against the base plate 101 through the arcuate surface of the spherical portion 116. According to the structure provided in this embodiment, the spherical portion 116 can reduce friction between the lifting screw 111 and the base plate 101, making adjustment easier and reducing labor intensity. This is beneficial to further improving the flexible adjustment effect of the adjustable motor support structure in this embodiment.

[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The lifting screw 111 also includes a hexagonal portion 117 located between the threaded portion 115 and the spherical portion 116; the hexagonal portion 117 forms a hexagonal prism structure coaxial with the threaded portion 115. According to the structure provided in this embodiment, the hexagonal portion 117 allows the operator to easily use tools to rotate the lifting screw 111, which is beneficial to further improve the flexible adjustment effect of the adjustable motor support structure in this embodiment.

[0044] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The adjustment assembly also includes multiple pads of different thicknesses (not shown); these pads are selectively placed between the support plate 104 and the top plate 103. According to the structure provided in this embodiment, after adjusting the height and level of the support plate 104 (i.e., adjusting the center height and level of the target motor 200) by using the lifting screw 111, placing the pads between the support plate 104 and the top plate 103 allows the support plate 104 to be stably maintained at a predetermined height. This allows the lifting screw 111 to remove its supporting force on the support plate 104. This not only enables the lifting screw 111 to be used stably for a longer period but also allows it to return to its initial position, thereby further improving the flexibility of the adjustable motor support structure in this embodiment and ensuring the long-term stability of the target motor 200's position.

[0045] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The adjustment assembly also includes several fasteners 118; coaxial connecting holes 119 are correspondingly provided on the support plate 104 and the top plate 103, and the support plate 104 is detachably connected to the top plate 103 through the fasteners 118 that can be installed in the connecting holes 119. According to the structure provided in this embodiment, the height and level of the support plate 104 (i.e., the center height and level of the target motor 200) are adjusted by the lifting screw 111, and after a suitable shim is placed between the support plate 104 and the top plate 103, the lifting screw 111 is loosened to remove the supporting force on the support plate 104, and then the fasteners 118 are tightened to make the support plate 104 and the top plate 103 securely connected. In this way, the fasteners 118 installed in the connecting holes 119 can maintain a stable relative position relationship between the support plate 104 and the top plate 103, which is beneficial to further improve the flexible adjustment effect of the adjustable motor support structure in this embodiment and the effect of keeping the position of the target motor 200 stable for a long time.

[0046] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4A receiving cavity 120 for accommodating a fastener 118 is formed on the support plate 104, and the fastener 118 does not extend beyond the receiving cavity 120 in the normal direction of the support plate 104. According to the structure provided in this embodiment, the receiving cavity 120 formed on the support plate 104 can accommodate the fastener 118 and avoid mechanical interference between the fastener 118 and the movement of the target motor 200, which is beneficial to further improve the flexible adjustment effect of the adjustable motor support structure in this embodiment.

[0047] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The support plate 104 has several mounting holes 121 on the side opposite to the top plate 103 for connecting the target motor 200. In this embodiment, the mounting holes 121 are threaded holes, and their positions are adapted to the positions of the reserved holes on the base of the target motor 200. According to the structure provided in this embodiment, the mounting holes 121 formed on the support plate 104 enable the target motor 200 to be installed and fixed on the support plate 104 more quickly. Here, firstly, the lifting screw 111, the first screw 109, and the second screw 110 are all in the initial reset state. At this time, the support plate 104 and the top plate 103 abut against each other, and the front ends of the first screw 109 and the second screw 110 are respectively retracted into the threaded holes of the first set screw seat 106 and the second set screw seat 107. Fasteners 118 are installed in the connecting hole 119 to initially loosely connect the support plate 104 and the top plate 103. The target motor 200 is placed on the support plate 104 and the target motor 200 is then installed. The side of the base is parallel to the side of the support plate 104. The bolts for mounting the target motor 200 are screwed into the mounting hole 121 through the reserved holes on the base and locked. Then, the first screw 109, the second screw 110 and the lifting screw 111 are adjusted to make the output shaft of the target motor 200 coaxial with the input shaft of the pump unit. After placing a suitable shim between the support plate 104 and the top plate 103, the lifting screw 111 is loosened to remove the supporting force on the support plate 104. Then, the fasteners 118 are tightened to make the support plate 104 and the top plate 103 securely connected, thus completing the installation and adjustment of the target motor 200. This helps to further improve the flexible adjustment effect of the adjustable motor support structure in this embodiment.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
