The utility model provides a lifting device of tiebar nut for handling when the tiebar nut of large-scale die casting machine is installed and is dismantled, as shown in figure 1, this lifting device includes hoist and mount frame 1, bracing piece 3 and support cover 2, bracing piece 3 with hoist and mount frame 1 fixed connection, support the periphery that bracing piece 3 was located to 2 covers of cover, be equipped with bearing 4 between bracing piece 3 and support cover 2, make bracing piece 3 and support cover 2 and can rotate relatively. Specifically, the one end of bracing piece 3 and the bottom fixed connection of hoisting frame 1 install two bearings 4 on bracing piece 3, support cover 2 from the bracing piece 3 relative other end cover on bracing piece 3, and the outer lane of bearing 4 and the inner peripheral surface interference fit who supports cover 2, interference fit is exempted from with the periphery of bracing piece 3 to the inner circle of bearing 4, makes to support cover 2 and can rotate around the axis of bracing piece 3 on bracing piece 3. Concretely, 3 accessible threaded connection spare fixed connection of bracing piece are in hoisting frame 1, and bracing piece 3 passes through hexagon socket head cap screw fixed connection in this application in hoisting frame 1.

When the installation tie bar nut, pass the hoist and mount groove at the device top with the suspender, hoist and mount frame 1 hangs on the lifting hook through the suspender, starts the lifting hook with the hoist engine, stretches into the tie bar nut with the supporting sleeve in, can with the position of tie bar nut handling to the tie bar of die casting machine, then through the rotatory tie bar nut of mounting tool, make the tie bar of its screw in die casting machine. Similarly, when disassembling the tie bar nut, firstly, the tie bar nut is rotated by an installation tool to extend out of the tie bar of the die casting machine for a certain distance; hoisting the hoisting tool to the position of a tie bar of a die casting machine, and enabling the supporting sleeve 2 of the hoisting tool to extend into the part of the tie bar nut extending out of the tie bar; then, the mounting tool is used for continuously rotating the tie bar nut, so that the tie bar nut is sleeved on the supporting sleeve 2. The above-mentioned mounting tool for a rotary tie bar nut is of prior art or common general knowledge and may, for example, be an electric mounting device as disclosed in the chinese utility model patent application No. 200420118184.3.

This application is through connecting support rod 3 on hoist and mount frame 1 to will support cover 2 and establish on support rod 3 through bearing 4 cover, make support rod 3 can rotate. When the tie bar nut is installed or dismantled, the tie bar nut is borne on the supporting sleeve 2, and the supporting sleeve 2 can rotate, so that the rotation of the tie bar nut can drive the supporting sleeve 2 to rotate, and the friction between the tie bar nut and a hoisting tool is reduced. Therefore, when the operating personnel installs or removes the tie bar nut, the rotating speed of the tie bar nut can be increased, and the thread structure of the tie bar nut is not easy to be damaged due to excessive friction when rotating; the tie bar nut can screw in or screw out the tie bar fast and smoothly, and then reduces the operating time of assembly or dismantlement of tie bar nut.

Further, support cover 2 has relative first terminal surface and the second terminal surface that sets up, and the periphery of bracing piece 3 is located to the first terminal surface cover of support cover 2, supports the second terminal surface fixedly connected with supporting disk 5 of cover 2, and the outer peripheral face of supporting disk 5 has the thread structure with the internal thread matched with of tiebar nut, and the external diameter of supporting disk 5 slightly is greater than the external diameter of support cover 2. When installing or dismantling the tiebar nut, can aim at the screw hole of tiebar nut with lifting device's support cover 2 and supporting disk 5 earlier, then rotatory tiebar nut makes its internal thread spiral shell structure with the supporting disk 5 earlier mutually spiral shell structure spiral shell, tiebar nut screw in support cover 2 back, the spiral shell structure of supporting disk 5 and the internal thread of tiebar nut spiral shell mutually spiral shell, can make the stable suit of tiebar screw thread on supporting cover 2, and then can avoid lifting device's the unexpected landing from supporting cover 2 of tiebar nut at the in-process of tiebar nut and drop from the sky, ensured operation safety.

Furthermore, a support disc 5 is fixedly mounted on the second end face of the support sleeve 2 through a threaded connection. In this embodiment, four holes are respectively opened on the second end surface of the support sleeve 2 and the side surface of the support disc 5, the support disc 5 is fixedly installed on the second end surface of the support sleeve 2 through four bolts, and the four bolts are circumferentially and uniformly distributed on the second end surface of the support sleeve 2, so that the support sleeve 2 is installed more firmly.

Further, because the tie bar nut is the metal material generally, the preferred nylon plastics thread that adopts of thread structure of supporting disk 5 in this embodiment can make the internal thread of tie bar nut more smooth when the thread structure with supporting disk 5 is in the spiro union each other, avoids the internal thread of tie bar nut to be scratched by the thread structure of supporting disk 5, plays the guard action to the internal thread of tie bar nut.

Further, hoist and mount frame 1 is installed dog 6 for stop the tiebar nut from supporting the landing on cover 2. When the tie bar nut is sleeved on the support sleeve 2 and the support plate 5, the thread structure of the support plate 5 is screwed with the internal thread of the tie bar nut, so that the tie bar thread is stably sleeved on the support sleeve 2, and the stop block 6 can also stop the tie bar nut from sliding off, thereby further ensuring the operation safety.

Specifically, hoist and mount frame 1's structure includes horizontal pole 11, hoist and mount portion 12 and connecting portion 13, and horizontal pole 11 has relative first end and the second end that sets up, hoist and mount portion 12 connect in the first end of horizontal pole 11, the one end of connecting portion 13 is connected with the second end of horizontal pole 11, the relative other end and bracing piece 3 fixed connection. In this embodiment, horizontal pole 11, hoist and mount portion 12 and connecting portion 13 integrated into one piece set up, and horizontal pole 11 and bracing piece 3 parallel arrangement each other moreover, and hoist and mount portion 12 and connecting portion 13 are located the relative both sides of horizontal pole 11 respectively, and hoist and mount portion 12 upwards extends from the first end of horizontal pole 11 promptly, and connecting portion 13 downwards extends from the second end of horizontal pole 11.

Furthermore, the cross bar 11, the connecting portion 13 and the support bar 3 are connected to form a frame structure, an opening for placing the tie bar nut is formed in one side of the frame structure, and the stop block 6 is rotatably installed at the first end portion of the cross bar 11 and located at the opening of the frame structure. During the use, the tiebar nut is put into from frame structure's opening to the suit is on supporting cover 2 and supporting disk 5, then stirs down or rotates the dog 6 of horizontal pole 11 first end, makes dog 6 block frame structure's part opening, and then can block tiebar nut from frame structure's opening roll-off.

Further, the hoisting part 12 is provided with a hanging strip hole 121 for the hanging strip to pass through, so that the crane can be conveniently connected with the hoisting tool through the hanging strip. Specifically, the suspender hole 121 of the hoisting part 12 is a strip-shaped hole, and is matched with a cloth-strip-shaped suspender for use, so that the tensile force borne by the hoisting tool is more balanced and stable.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
