Abstract

Multifunctional hand wheel turning device. The general method of turning is to use pipe tongs, spanners or other tools to fix the rotating shaft at the tail end of the motor for rotation, the working efficiency is low, and the used tools are different due to different shaft diameters of different types of motors. The composition of the utility model comprises: the locking device comprises a locking disc (1), wherein the center of the locking disc is provided with a shaft sleeve (4), the circumferential surface of the shaft sleeve is in threaded connection with a plurality of locking bolts (3), and the surface of the locking disc is provided with a plurality of clamping holes (2) which are uniformly distributed in circumference; the locking disc is fixedly connected with the handle (5). The utility model is used for the multifunctional hand wheel jigger.

Description

Multifunctional hand wheel turning device

Technical field

The utility model relates to a multifunctional handwheel turning device.

Background technique

Thermal power plants involve a lot of mechanical rotating equipment. When the rotating equipment fails, timely diagnosis and troubleshooting are required. Generally, it is necessary to test crank the rotating part to determine whether the mechanical part is stuck or the electrical control part is faulty. The general cranking method is to use pipe wrench, wrench or other tools to fix the end shaft of the motor for rotation, which has low work efficiency. , and because different types of motors have different shaft diameters, the tools used are also different.

Utility model content

The purpose of the utility model is to make up for the shortcomings of the existing technology and provide a multifunctional handwheel turning device.

The above purposes are achieved through the following technical solutions:

A multifunctional handwheel turning device, which is characterized in that it consists of a locking disk, the locking disk has a shaft sleeve in the center, and a plurality of locking bolts are threaded on the circumferential surface of the shaft sleeve. The surface of the locking disk has a plurality of clamping holes evenly arranged around the circumference;

The locking disk is fixedly connected to the handle.

In the multifunctional handwheel turning device, the handle includes a straight rod and a screw rod, the screw rod is fixed on one end of the straight rod, and a fixing nut is threadedly connected to the screw rod.

In the multifunctional handwheel turning device, the shaft sleeve is a circular sleeve.

The multifunctional handwheel turning device has four locking bolts.

beneficial effects

1. This utility model can be used for cranking and trial rotation of motors with different shaft diameters. It can also be used for bolt removal and reassembly in special occasions. It can also be used with an "F-type" wrench, which is convenient, labor-saving, and Efficient.

2. This utility model is convenient for motor cranking, and can quickly and effectively determine the jamming defects of the transfer equipment, or it can be used for slow transmission before the trial operation after the equipment maintenance is completed.

Detailed ways

A multifunctional handwheel turning device, which consists of a locking disk 1, which is a disc. The center of the locking disk has a shaft sleeve 4, which is a ring sleeve, and its inner diameter is 50mm. A plurality of locking bolts 3 are threadedly connected to the circumferential surface of the shaft sleeve. As shown in the figure, there are four locking bolts, evenly distributed on the circumferential surface of the shaft sleeve. The surface of the locking plate has There are a plurality of clamping holes 2 evenly arranged around the circumference. As shown in the figure, there are 6 clamping holes and the diameter of the clamping holes is 30mm.

The locking disk is fixedly connected to the handle 5.

The handle includes a straight rod 51 and a screw rod 52. The screw rod is fixed at one end of the straight rod. A fixing nut 53 is threadedly connected to the screw rod. When fixing, the fixing nut is disassembled, and then the handle The screw rod is inserted into the through hole of the locking plate. The through hole matches the diameter of the screw rod, and then the fixing nut is tightened to fix the handle.

Working principle: When using, loosen all four locking bolts, then put the shaft sleeve on the shaft diameter 6 of the motor 7, and then tighten each locking bolt to realize the clamping of the shaft diameter by the device, and hold it by hand. The handle can realize the rotation of the shaft diameter, and at the same time adjust the hole diameter through 4 locking nuts to lock the motor shafts with different journals. It can also be used with the "F-type" wrench. When larger torque is required, it needs to be used with the F-type wrench. When using an F-type wrench, insert the two wrench arms of the F-type wrench into the two adjacent holes of the locking plate, making it easy, labor-saving and efficient to operate.
