Description

Technical Field

[0001] The utility model relates to the technical field of hoisting fixtures, in particular to a motor stator hoisting fixture. Background Art

[0002] Currently, there are two common methods for moving or installing motor stators. One is to manually lower the stator and lift it, then pass a wire rope through the stator ground and use a crane or loader to lift the stator. However, this method is difficult to manually control given the heavy stator, and may cause the stator to bump and damage the stator. The other method is to place a clamp on the outside of the motor stator and lift the clamp to lift the stator. However, this method may cause the stator to fall off during the lifting process, resulting in the stator being scrapped. Utility Model Content

[0003] The utility model aims to overcome the above technical defects and provide a motor stator lifting fixture which is simple to install, firmly clamped and suitable for motor stators of different sizes.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A motor stator lifting fixture includes a suspension rod, a support plate, a fourth support rod, a positioning slide, and a sleeve; one end of the fourth support rod is connected to the support plate, and the other end of the fourth support rod is connected to one end of the positioning slide; the other end of the positioning slide is fixedly connected to the bottom of the sleeve, the sleeve is sleeved on the suspension rod, and the sleeve is slidably connected to the suspension rod.

[0006] Furthermore, it also includes a support seat and a plurality of support rods, one end of the support seat is connected to the support plate through the support rod, and the other end of the support seat is fixedly connected to the suspension rod.

[0007] Furthermore, there are three groups of support seats, and the angle between each two of the three groups of support seats is 120 degrees; there are three groups of support rods, and the angle between each two of the three groups of support rods is 120 degrees; there are three support plates, and the angle between each two of the three support plates is 120 degrees.

[0008] Furthermore, the distance between the positioning slide and the support seat is greater than the distance between an end of the fourth support rod away from the positioning slide and an end of the support rod away from the support seat.

[0009] Furthermore, the support seat includes three groups of support seats, namely the first support seat, the second support seat, and the third support seat, and the several support rods include the first support rod, the second support rod, and the third support rod; the first support seat and the support plate are connected by the first support rod, the second support seat and the support plate are connected by the second support rod, and the third support seat and the support plate are connected by the third support rod.

[0010] Furthermore, the first support rod, the second support rod, the third support rod and the fourth support rod are completely the same in size and shape, and the first support rod, the second support rod and the third support rod are arranged parallel to each other.

[0011] Furthermore, a plurality of positioning grooves are provided on the boom, and the sum of the distance from the positioning groove to the top of the boom and the length of the sleeve is greater than the distance from the support seat to the top of the boom.

[0012] Furthermore, the invention further comprises a lifting handle and a positioning handle, wherein the lifting handle is located at the top of the sleeve, the positioning handle is located between the lifting handle and the sleeve, and a positioning pin is provided on the positioning handle. The positioning pin is connected to the positioning handle, and the positioning pin is moved by gripping the positioning handle to achieve positioning and release.

[0013] Furthermore, a through hole is provided on a side of the sleeve close to the positioning handle, and the positioning pin passes through the through hole on the sleeve and matches the positioning groove.

[0014] Since the position of the sleeve can be fixed by matching the positioning pin with the positioning groove, the sleeve can be quickly moved and fixed, which greatly improves the working efficiency of the lifting fixture.

[0015] Furthermore, a rubber pad is fixedly connected to the side of the support plate away from the suspension rod, and the outer surface of the rubber pad is an arc-shaped surface.

[0016] The working process of a motor stator hoisting fixture of the utility model is as follows:

[0017] By holding the lifting handle and positioning handle, you can move them up and down. Since the positioning handle is connected to the sleeve, and the lifting handle is also connected to the sleeve, lifting the positioning handle can cause the sleeve to slide up and down along the boom. Since the bottom of the sleeve is fixedly connected to the positioning slide, lifting the positioning handle can drive the positioning slide up and down.

[0018] In the initial test state, lift the lifting handle and positioning handle, the sleeve moves upward, and the positioning slide connected to the sleeve moves upward at the same time, while the position of the boom and the support seat remain unchanged. During the process of lifting the lifting handle and positioning handle, the fourth support rod connected to the positioning slide has a tendency to move closer to the boom, driving the support plate toward the boom. The support plate drives the support rod connected to the support seat to move closer to the boom. At this time, the distance between the left and right support plates decreases. When the distance between the left and right support plates is smaller than the inner diameter of the motor stator, the boom can be lifted and the entire motor stator lifting fixture can be placed into the motor stator hole.

[0019] Press down the lifting handle and release the positioning handle. At this time, the fourth support rod connected to the positioning slide has a tendency to move away from the boom, driving the support plate to move away from the boom. The support plate drives the support rod connected to the support seat to move away from the boom. At this time, the distance between the left support plate and the right support plate increases until the lifting handle cannot be pressed down. At this time, the outer wall of the support plate is against the inner wall of the motor stator hole.

[0020] Insert the locating pin through the through hole on the sleeve into the locating groove on the boom to prevent the sleeve from moving up and down and fix the sleeve position. At this time, lift the boom to lift the motor stator.

[0021] During the lifting process, the boom moves upward, driving the support seat to move upward. The support rod connected to the support seat has a tendency to move away from the boom, causing the support plate to move away from the boom. Since the inner diameter of the motor stator is fixed, the inner diameter of the motor stator and the outer wall of the support plate fit more closely during this process, thereby preventing the motor stator from falling.

[0022] After reaching the designated position, lower the motor stator, hold the lifting handle and positioning handle, disengage the positioning pin from the positioning slot, lift the lifting handle upwards, reduce the support plate diameter, and then easily remove the lifting fixture.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] The lifting fixture provided by the utility model is simple to operate, convenient to use, and has a strong clamping force, and can be applied to motor stators of motor stators of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS
