Description

Technical Field

[0001] This utility model relates to the field of industrial equipment installation technology, specifically a slant shaft motor limiting structure. Background Technology

[0002] With the development of industrial technology, horizontal motors are inevitably used in industrial sectors such as hydropower construction, thermal power generation, metallurgy, and light industry. The required size of the motor varies depending on its function. For example, a 1600 kW hydraulic motor weighs 9 tons excluding the base frame. Horizontal motors are generally installed by bolting the stator to the base frame. When the motor load is equipment such as a dredging cutter or an axial flow pump, it needs to be installed at an angle (motors installed at an angle are also called slanted shaft motors, and the shaft extension end is usually facing downwards).

[0003] Because the axial relative position between the horizontally mounted motor and the load equipment needs to be adjusted, the bolts and the mating holes on the base and frame are all rough fits. The traditional rough fit fixing method of the motor means that the axial position of the motor is maintained only by the friction between the motor body and the base and between the base and the mounting foundation after the bolts are tightened and the washers are tightened. During long-term operation, due to factors such as vibration, the relative displacement between the motor and the base and between the base and the mounting foundation can easily occur, affecting the shaft system safety of the entire equipment line.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this inclined shaft motor limiting structure, when the stator frame of the motor is fixed on the inclined mounting base by setting up a base frame, a push pad mechanism is first set between the stator frame and the base frame as a pad block. Then, a limiting mechanism is set at the bottom position of the inclined stator frame and installed on the base frame. In cooperation with the push pad mechanism, it provides a limiting force to the motor stator frame. When the motor undergoes relative displacement along the inclined plane due to various factors during long-term operation, the push pad mechanism will provide a locking force to the stator frame, which can reliably support the entire motor, avoid affecting the safety of the shaft system of the entire equipment line, and improve the safety of the motor during long-term operation.

[0017] 2. The limiting structure of this inclined shaft motor uses a mounting mechanism to fix the mounting mechanism in one position with internal angle bolts. Then, a pushing mechanism is set up so that the mounting mechanism provides a lateral thrust to the limiting mechanism. During installation, the pushing mechanism and the pushing pad mechanism are pressed together, which provides an upward thrust to the motor stator frame along the inclined plane. This force is opposite to the force that causes the relative displacement of the motor stator frame due to vibration and other factors, thus offsetting the influence of the force to a certain extent and improving the stability of motor operation.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-9 A limiting structure for a slant-axis motor, the slant-axis motor includes: a stator frame 1 integrally disposed on its side, a base frame 2 installed below the stator frame 1, the base frame 2 being installed on a mounting foundation 5 located at the bottom by anchor bolts, a pushing pad mechanism 4 being sandwiched between the stator frame 1 and the base frame 2, a limiting mechanism 3 being attached below the pushing pad mechanism 4 at the end of the stator frame 1, and the limiting mechanism 3 being installed on the base frame 2;

[0030] A first pad 6 is sandwiched at the joint between the limiting mechanism 3 and the pushing mechanism 4. A second pad 7 is provided between the limiting mechanism 3 and the base frame 2. A fastening mechanism 8 is installed on the limiting mechanism 3, and a pushing mechanism 9 is provided at the end of the fastening mechanism 8, which passes through the abutment of the limiting mechanism 3 and the pushing mechanism 4.

[0031] The limiting mechanism 3 includes a first steel plate 31 and a second steel plate 32. The ends of the first steel plate 31 and the second steel plate 32 are welded together at a 90-degree angle. A first reinforcing plate 35 is welded to the middle of the angle between the first steel plate 31 and the second steel plate 32. The first steel plate 31 has mounting grooves 36 on both sides of the first reinforcing plate 35. The mounting grooves 36 are installed on the base frame 2 by means of internal angle bolts 10. The second steel plate 32 has first insertion holes 34 on both sides of the first reinforcing plate 35. The end of the pushing mechanism 9 is inserted into the first insertion hole 34.

[0032] The inner wall of the mounting groove 36 is strip-shaped, and the inner corner bolt 10 is slidably connected to the inner wall of the mounting groove 36. When the inner corner bolt 10 passes through the mounting groove 36, before tightening, the tightening of the push-fixing mechanism 9 can be adjusted so that the mounting mechanism 8 can give the limiting mechanism 3 an upward push along the inclined surface through the push-fixing mechanism 9, so that the limiting mechanism 3 and the push pad mechanism 4 are pressed together when the motor stator frame 1 is installed.

[0033] The second steel plate 32 has a groove 33 on its side, and the first pad 6 is sandwiched inside the groove 33. The first pad 6 is made of galvanized steel plate. By utilizing the characteristics of galvanized steel plate, the contact surface between the limiting mechanism 3 and the pushing mechanism 4 is protected, and the friction damage to the limiting mechanism 3 and the pushing mechanism 4 during motor operation is reduced.

[0034] The mounting mechanism 8 includes a clamping block 81 with a slot 82 in the middle. The first reinforcing plate 35 is located inside the slot 82. One end of the clamping block 81 has an inner groove 84, and the other end has an inner threaded hole 83. The position of the inner threaded hole 83 corresponds to the position of the first insertion hole 34. One end of the pushing mechanism 9 is set in the inner threaded hole 83. The inner groove 84 has a threaded hole 85. The bottom end of the inner angle bolt 10 passes through the threaded hole 85 and the mounting groove 36 and is installed on the base frame 2. By setting the mounting mechanism 8, the inner angle bolt 10 is used to fix the mounting mechanism 8 in a position. Then, by setting the pushing mechanism 9, the mounting mechanism 8 gives the limiting mechanism 3 a lateral push force, thereby pressing the pushing mechanism 9 and the pushing pad mechanism 4 together during installation.

[0035] The push-fixing mechanism 9 includes an integrally connected pusher 91 and lead screw 92. A pusher plate 93 is sleeved at the connection between the pusher 91 and the lead screw 92. A nut 94 is provided on the side of the pusher plate 93 near the lead screw 92. The end of the lead screw 92 is threadedly connected to one end of the mounting mechanism 8. By utilizing the connection between the lead screw 92 and the mounting mechanism 8, the push-fixing mechanism 9 can provide a pushing force between the limiting mechanism 3 and the mounting mechanism 8 when rotating. Thus, when the mounting mechanism 8 is fixed, the limiting mechanism 3 is pushed upward along the inclined plane, giving a reaction force to the relative displacement of the motor stator frame after being affected by vibration, which has a certain counteracting effect.

[0036] The base frame 2 has a locking groove 11 on its top. The size of the inner wall of the locking groove 11 is adapted to the size of the second pad 7. By opening the locking groove 11, the second pad 7 is completely embedded in it, so that when the pushing mechanism 9 is turned to push the limiting mechanism 3, the second pad 7 will not be affected by the movement of the limiting mechanism 3.

[0037] The pushing mechanism 4 includes a strip pad 41, which is located between the stator frame 1 and the base frame 2. The end of the strip pad 41 is welded with a backing plate 42 at a 90-degree angle. The side of the backing plate 42 overlaps with the limiting mechanism 3. By welding the backing plate 42 to the end of the strip pad 41, the limiting mechanism 3 directly contacts the backing plate 42, providing a larger pushing contact surface and ensuring the limiting effect of the limiting mechanism 3 on the motor stator frame 1.

[0038] Among them, a pressure plate 43 is welded to the side of the abutment plate 42 near the stator frame 1. The pressure plate 43 is arranged parallel to the strip pad 41, and the distance between the pressure plate 43 and the strip pad 41 corresponds to the thickness of the stator frame 1. A second reinforcing plate 44 is welded to the middle of the angle between the abutment plate 42 and the pressure plate 43. A second insertion hole 45 is opened on the surface of the abutment plate 42 on both sides of the second reinforcing plate 44. The position of the second insertion hole 45 corresponds to the position of the first insertion hole 34. By setting the second reinforcing plate 44 and the pressure plate 43, when the limiting mechanism 3 contacts the abutment plate 42 and applies an upward pushing force, the second reinforcing plate 44 will transfer the pushing force received by the abutment plate 42 to the pressure plate 43, thereby guiding the force to the stator frame 1, so that the stator frame 1 can fully bear the pushing force of the limiting mechanism 3.

[0039] The working principle is as follows: When installing the motor on the mounting foundation 5, firstly, the base frame 2 is installed on the mounting foundation 5 using anchor bolts. Then, the push pad mechanism 4 is clamped between the stator frame 1 and the base frame 2, and the stator frame 1 is installed on the base frame 2. After the stator frame 1 is installed, the second pad 7 is placed into the locking groove 11. Then, the limiting mechanism 3 is placed on the second pad 7. The inner angle bolt 10 is installed on the base frame 2 by passing through the fixing mechanism 8 and the limiting mechanism 3. Before tightening the inner angle bolt 10, the first pad 6 is inserted between the limiting mechanism 3 and the push pad mechanism 4, and the push fixing mechanism 9 is tightened so that the limiting mechanism 3 and the push pad mechanism 4 are tightly attached together through the first pad 6. Finally, the inner angle bolt 10 is tightened.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
