The application provides a lifting appliance for lifting a disc-shaped object, which comprises a base 1, a positioning mechanism 2, a clamping mechanism 3 and a lifting mechanism 4. The positioning mechanism 2 comprises a body and a positioning part 21 arranged on the body, wherein the body is connected with the base 1 and is used for being matched with the disc-shaped object so as to position the disc-shaped object. The clamping mechanism 3 is connected to the base 1 and comprises a first clamping member 31 and a second clamping member 32. The first clamping member 31 and the second clamping member 32 are respectively located at two sides of the positioning mechanism 2, and the first clamping member 31 and the second clamping member 32 are used for forming a clamping space matched with the outer diameter of the disc to clamp the disc. The hoisting mechanism 4 is disposed on one side of the base 1 away from the positioning mechanism 2, or on one side of the positioning mechanism 2 away from the positioning portion 21.

In real life, the lifting of the disk by the lifting appliance is involved in many scenes. Such as roll grinders, mainly use grinding wheels for roll grinding. After the grinding wheel is used for a period of time, if the grinding wheel is seriously worn, a new grinding wheel needs to be replaced, and the grinding wheel can be lifted and replaced by using the lifting appliance.

For convenience of explanation, a hanger in use will be described by taking a grinding wheel as an example.

As shown in fig. 1, the spreader includes a base 1, a positioning mechanism 2, a clamping mechanism 3, and a hoisting mechanism 4. The base 1 is connected with the positioning mechanism 2 and the clamping mechanism 3, and the first clamping piece 31 and the second clamping piece 32 of the clamping mechanism 3 are respectively positioned at two sides of the positioning mechanism 2. A clamping space matched with the outer diameter of the grinding wheel is formed between the first clamping piece 31 and the second clamping piece 32. The hoisting mechanism 4 in the present embodiment is provided on the side of the positioning mechanism 2 away from the positioning portion 21, but in other embodiments, the hoisting mechanism 4 may be provided on the side of the base 1 away from the positioning mechanism 2.

In this case, a hook of the crane is inserted into the hoisting mechanism 4 of the base 1 by using equipment such as a crane, and the entire hanger is moved to the vicinity of the grinding wheel by driving the crane. Then, the grinding wheel is initially positioned by the positioning portion 21 of the positioning mechanism 2, and then the first clamping member 31 and the second clamping member 32 are adjusted, so that the outer side wall of the grinding wheel is abutted to the first clamping member 31 and the second clamping member 32, that is, the grinding wheel is located in the clamping space formed by the first clamping member 31 and the second clamping member 32. And finally, the lifting appliance and the grinding wheel clamped by the lifting appliance are transported to a target position by using the lifting appliance.

When clamping the grinding wheel, because the positioning part 21 can preliminarily position the grinding wheel, the grinding wheel is prevented from moving when the grinding wheel is clamped by the clamping piece. Further, since the first and

second clamps

31 and 32 are respectively located on both sides of the positioning portion 21, it can be seen that the positioning portion 21, the first clamp 31, and the second clamp 32 are located on the same straight line. Therefore, the grinding wheel can be stably clamped, and the stability of the grinding wheel in the transportation process is improved.

In an embodiment, the clamping mechanism 3 further comprises a first swing arm 33 and a second swing arm 34. The first swing arm 33 and the second swing arm 34 are respectively connected to two ends of the base 1 through rotating parts, the first clamping piece 31 is arranged on the first swing arm 33, and the second clamping piece 32 is arranged on the second swing arm 34.

When the clamping mechanism 3 operates, the first swing arm 33 and the second swing arm 34 both rotate around the end of the base 1 under the action of gravity and drive the clamping piece mounted on the swing arms to rotate. The state of the holding mechanism 3 shown in fig. 1 is taken as an example. The first swing arm 33 rotates anticlockwise around the base 1 under the action of self gravity and drives the first clamping piece 31 to rotate anticlockwise; at this time, the second swing arm 34 also rotates clockwise around the base 1 under the action of its own gravity, and drives the second clamping member 32 to rotate clockwise. When the first swing arm 33 and the second swing arm 34 reach the preset position, the first swing arm 33 and the base 1 form a certain included angle therebetween, and the second swing arm 34 and the base 1 also form a certain included angle therebetween. It will be appreciated that the first and

second clamping members

31, 32 clamp the outer side wall of the grinding wheel at respective angles to the outer side wall of the grinding wheel. So set up for first swing arm 33 and second swing arm 34 all take place to rotate under the effect of self gravity, in order to improve the clamping-force of the holder of locating on the swing arm.

In an embodiment, an abutting portion (not shown in the figure) is disposed at an end of the base 1, and the first swing arm 33 further includes a limiting portion (also not shown in the figure), the limiting portion is located at an end of the first swing arm 33 close to the base 1, the first swing arm 33 can be switched between a first state and a second state, the first swing arm 33 is fixed relative to the base 1 in the first state, and the first swing arm 33 rotates relative to the base 1 in the second state until the limiting portion of the first swing arm 33 abuts against the abutting portion of the base 1.

So set up, can make first swing arm 33 and second swing arm 34 rotate to preset the position, avoid it to rotate excessively. And set up the butt portion on base 1, need not to set up extra locating part, simplified the structure.

Of course, the jig further includes a fixing member that fixes the first swing arm 33 in the first state. The fixing member may be a pin, and the first swing arm 33 can be made stationary relative to the base 1 by passing the pin through the joint of the first swing arm 33 and the base 1 and then tightening the pin with a nut. In order to prevent the nut from loosening, the end of the pin shaft matched with the nut can be opened. A cotter pin is inserted into the opening to prevent the nut from falling off the pin.

Referring to fig. 1, the first clamping member 31 is movably disposed on the first swing arm 33, and the second clamping member 32 is movably disposed on the second swing arm 34. When clamping the grinding wheel, the first clamping piece 31 and the second clamping piece 32 can be respectively moved towards the direction far away from the base 1, so that the distance between the first clamping piece 31 and the second clamping piece 32 is larger than the outer diameter of the grinding wheel to be clamped. After the grinding wheel is positioned, the first clamping piece 31 and the second clamping piece 32 can be moved towards the direction close to the base 1 until the first clamping piece 31 and the second clamping piece 32 are both abutted to the outer side wall of the grinding wheel.

So set up, can make the interval between first holder 31 and the second holder 32 adjustable, not only be convenient for fix the emery wheel and dismantle, thereby still avoided holder and emery wheel to collide and lead to the holder impaired.
