Detailed Description

The invention will be described in more detail below by way of example with reference to the accompanying drawings:

referring to fig. 1a-3, a rotor disk rotating device of a high torque device comprises clamping disks 1, disk moving rods 2, connecting fasteners 3 and protective gaskets 4, wherein the two clamping disks 1 and the two protective gaskets 4 are buckled and clamped on the excircle of an input or output shaft of the device by using the connecting fasteners 3, the two disk moving rods 2 are respectively inserted into opposite inserting holes of the 2 clamping disks 1, and the rotation of a rotor is realized by simultaneously using the disk moving rods 2 and the two moving clamping disks 1 on two sides of the shaft. Two clamping disks 1 are clamped on the outer circle of the shaft sleeve, and the rotor is driven to rotate by friction force evenly distributed along the circumference, so that the rotor and the bearing are prevented from being damaged due to overlarge local stress when the rotor is driven by the disks.

This device uses the dish of sled movable disk to move the pole 2 to move the rotor of big rotation torque equipment with the help of lever principle, two operating personnel alright with carrying out the dish axle operation, avoid using crane or chain block dish axle and lead to the impaired danger of rotor.

The disc moving rod 2 and the clamping disc 1 are designed into a split structure, the disc moving rod 2 is inserted into the insertion hole of the clamping disc 1 during use, and the disc moving rod 2 is pulled out and separately placed after use, so that the device is convenient to store and transport. The protective gasket 4 made of rubber materials is added between the clamping disc 1 and the shaft outer circle, so that the risk of damaging the shaft end due to contact, friction and collision among metals can be prevented, and the dynamic balance state of the shaft sleeve is effectively protected.

The clamping disc 1 is formed by cutting a steel plate with the thickness of more than or equal to 10mm according to the size and then bending, and two reinforcing rib plates are respectively arranged at the connecting positions of the two ends of the clamping disc 1 to ensure that the strength and the rigidity of the whole body meet the requirements; the connecting fastener 3 is a combination of a bolt, a nut and a washer, so that the stability of connection is ensured; 3 coil moving rod sleeves are uniformly distributed on each clamping disc 1, are made of thick-walled seamless steel tubes and are welded on the excircle of each clamping disc 1, and proper sleeves can be selected to be inserted according to the positions of operators during operation, so that the operators can apply force conveniently; two protection gaskets 4 are made by rubber pads with the thickness of 5mm, and are respectively filled in the 2 clamping discs 1 to play the roles of protecting the surface of the shaft and buffering the initial radial force. The coiled rod is a seamless steel pipe with nominal size lower than that of the sleeve by one level, the strength can meet the requirement, and meanwhile, the coiled rod is light in weight and convenient to transport and carry.

The installation and operation process of the invention is as follows:

(1) each part of the device is transported to a construction site and comprises two clamping discs (1), two disc moving rods (2), two sets of connecting fasteners (3) and two protective gaskets (4);

(2) placing and wrapping 1 protective gasket (4) on the upper part of the outer surface of the shaft;

(4) placing another 1 protective pad (4) inside another 1 clamping disc (1) and lifting it to the lower outer surface of the joker;

(5) adjusting the position to align the connecting holes of the two clamping discs (1) and simultaneously ensure that the two protective gaskets (4) are aligned and completely wrap the outer circle of the shaft;

(6) connecting fasteners (3) are respectively inserted into two sides of the clamping discs (1) and are sequentially and alternately screwed, and the same clearance is required to be ensured between the two sides of the two clamping discs (1);

(7) selecting a plug hole with proper height and operation space, and respectively inserting the two disc moving rods (2) into the plug holes on the two clamping discs (1);

(8) 1 operator is respectively arranged at the left side and the right side of the shaft, and two persons push the movable disc moving rod (2) simultaneously according to the rotation direction specified by the equipment, so that the uniform force application, consistent rhythm and slow speed are ensured;

(9) when the shaft rotates to a required position, operators on two sides stop applying force at the same time to ensure that the shaft stops at a specified angle;

(10) after the device is used, the two disc moving rods (2) are pulled out, the two sides of the disc moving rods are loosened to connect the fasteners (3), the clamping disc (1) and the protective gasket (4) below the disc moving rods are firstly disassembled, then the clamping disc (1) and the protective gasket (4) above the disc moving rods are disassembled, and all the parts are respectively conveyed to a storage position.
