Description

Technical Field

[0001] This utility model relates to a motor base height adjustment tool, belonging to the technical field of equipment in the electromechanical installation industry. Background Technology

[0002] During the motor installation and alignment process, when the motor base needs to be raised or lowered, it is generally necessary to use a pry bar to lift the motor. If the prying point is not chosen properly or the motor itself is heavy, it will be time-consuming and laborious, increase the difficulty of maintenance, and pose a certain degree of danger. Utility Model Content

[0003] The purpose of this utility model is to provide a motor base height adjustment tool that can conveniently and quickly adjust the height of the motor base, greatly reducing the difficulty and workload of the work and solving the problems existing in the background technology.

[0004] The technical solution of this utility model is:

[0005] A motor base height adjustment tool includes a metal spring, a housing, a support column, a thrust bearing, a hook, and a lifting nut. The housing is rotatably connected to the support column via the thrust bearing. The support column has several grooves along its circumference, and each groove contains a hook and a metal spring that mates with the hook. The lifting nut is threaded onto the housing. The hook is L-shaped, with its upper end resting on the lifting nut and its lower end having a hook head that mates with the motor base.

[0006] The outer casing is provided with fixing bolts in the radial direction to cooperate with the hook.

[0007] The support column has four evenly arranged grooves along its circumference.

[0008] The metal spring is fixed in the groove of the support column.

[0009] The upper end of the support column is provided with a through hole.

[0010] The outer shell is cylindrical.

[0011] The advantages of this invention are: it avoids the need to use a pry bar, and the height of the motor base can be easily and quickly adjusted simply by rotating the outer casing, greatly reducing the difficulty and workload of the work. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and examples.

[0018] See attached document Figure 1-4 A motor base height adjustment tool includes a metal spring 1, a housing 2, a support column 3, a thrust bearing 4, a hook 5, and a lifting nut 6. The housing 2 is rotatably connected to the support column 3 via the thrust bearing 4. The support column 3 has several grooves 10 in the circumferential direction. Each groove 10 is provided with a hook 5 and a metal spring 1 that cooperates with the hook 5. The lifting nut 6 is threadedly connected to the housing 2. The hook 5 is L-shaped, with its upper end overlapping the lifting nut 6, and its lower end having a hook head 11 that cooperates with the motor base.

[0019] In this embodiment, refer to the appendix Figure 1-4 The tool comprises a metal spring 1, a housing 2, a support column 3, a thrust bearing 4, a hook 5, a lifting nut 6, a fixing bolt 7, a through hole 8, a shoulder 9, a groove 10, and a hook head 11, wherein:

[0020] The outer casing 2 is cylindrical. The upper part of the support column 3 has a through hole 8 and a shoulder 9 that mates with the thrust bearing 4. The lower part of the support column 3 has four evenly arranged grooves 10 in the circumferential direction. The size of the grooves 10 matches the hook 5. The hook 5 is L-shaped and has a hook head 11 at the lower end. It is assembled in the following way:

[0021] First, connect the outer casing 2 and the support column 3 via the thrust bearing 4. Then, attach the metal spring 1 to the groove 10 of the support column 3. Simultaneously, suspend the upper end of the hook 5 on the lifting nut 6, with an overlap length of not less than 15mm. The gap between the lifting nut 6 and the support column 3 should not be less than the minimum thickness of the vertical section of the hook 5. Next, insert the lifting nut 6 with the hook 5 from the bottom of the support column 3, and simultaneously guide the hook 5 into the groove 10 of the support column 3. The lifting nut 6 and the outer casing 2 are connected by threads. Finally, install the fixing bolt 7 and tighten the fixing bolt 7 appropriately against the hook 5 to maintain the stability of the entire tool.

[0022] In use, estimate the depth of the motor anchor bolt holes, adjust the lifting nut 6 to the appropriate position, and tighten the fixing bolt 7 to ensure that the hook head 11 of the hook 5 is in the groove 10 of the support column 3. Then, insert the lower end of the support column 3 into the motor anchor bolt holes and ensure it is in full contact with the foundation bottom surface. Loosen the fixing nut 7 and gently move the support column 3 up and down until the hook head 11 of the hook 5 hooks onto the bottom surface of the motor base and cannot move freely. Finally, use an auxiliary tool to fix it through the through hole 8 at the upper end of the support column 3, and rotate the outer casing 2 to raise and lower the motor base.

[0023] During dismantling, tighten the fixing bolt 7, press the hook head 11 of the hook 5 into the groove 10 of the support column 3, and then remove the tool.
