Description

Technical Field

[0001] The utility model relates to the technical field of overhead crane hoisting motor control, and more specifically, to an overhead crane hoisting motor positioning adjustment device. Background Art

[0002] Usually, the motor is installed by placing the motor directly on the fixed base, passing the fixing screw through the hole on the fixed base, and then tightening the bolt to fix the motor on the fixed base. This method can still meet the use requirements for sites with small motor capacity, low speed, and low frequency of motor use.

[0003] However, in the case of special equipment such as crane motors with high speed, high frequency of use and large motor capacity, the original fixing method cannot effectively adjust and position the crane motor. When the crane motor rotates at a high speed, due to the low coaxiality between the crane motor and the reducer, long-term use can easily cause wear of the coupling and motor bearings, leading to equipment failure. Therefore, it is urgent to research and design a new type of positioning and adjustment device for crane motors. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a positioning adjustment device for a crane hoisting motor in view of the above-mentioned deficiencies in the prior art, so as to facilitate adjustment of the coaxiality of the hoisting motor and the reducer, extend the service life of the equipment, and ensure the stable operation of the equipment.

[0006] As a further improvement, a first slide groove is provided on the bottom plate, and a first sliding block is provided at the bottom of each of the wedge-shaped blocks, and the first sliding block is slidably installed in the first slide groove.

[0007] Furthermore, a bearing is provided at one end of the wedge block, and one end of the first screw is rotatably connected to the bearing.

[0008] Furthermore, a telescopic column is provided on the bottom plate, and the other end of the telescopic column is connected to the bottom of the fixed base.

[0009] Furthermore, the telescopic column sleeve is provided with a spring, one end of the spring is connected to the bottom plate, and the other end of the spring is in contact with the fixed base.

[0010] Furthermore, a second nut is welded to one end of each of the first screw rods and the second screw rods.

[0011] Beneficial Effects

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The utility model is a positioning and adjusting device for a crane hoisting motor. The height of the hoisting motor is largely adjusted by a first nut on a support rod, and then the height of the hoisting motor is fine-tuned by a wedge block on a bottom plate. The hoisting motor is fine-tuned left and right by an adjusting mechanism composed of a baffle plate and a second screw on a fixed base. The positioning and adjusting device can make slight adjustments to the height position and plane position of the hoisting motor, and can better adjust the coaxiality between the hoisting motor and the reducer, thereby extending the service life of the equipment and ensuring the stable operation of the equipment.
