DETAILED DESCRIPTION

[0018] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0019] Example

[0020] See also Figure 1-3 , the utility model provides a technical solution: an automatic hanging device for a feeder of a light crystal pulling furnace;

[0021] The present invention aims to provide a device that is conducive to automatically taking out and hanging the feeder of the optical crystal pulling furnace. Most of the existing optical crystal pulling furnace feeders adopt the manual taking and hanging method, which is inefficient.

[0022] Based on the above problems, the components in this case include a base frame 1, a rotating frame 2 is arranged on the upper side of the base frame 1, a furnace body 3 is fixedly connected to the front end of the rotating frame 2, a feeder 4 is plugged into the top of the furnace body 3, a first connecting seat 5 is arranged on the top of the feeder 4, a lifting ring 6 is installed on the top of the first connecting seat 5, a ring frame 7 is arranged on one side of the base frame 1, a connecting assembly is arranged on the upper side of the ring frame 7, a support seat 8 is installed on the lower side of the ring frame 7, a cylinder 9 is installed on the top of the support seat 8, a traction device 10 is arranged on the other side of the base frame 1, a hydraulic push rod 11 is hinged on the lower side of the base frame 1, and the output end of the hydraulic push rod 11 is hinged to one side of the rotating frame 2;

[0023] The connecting assembly includes: a second connecting seat 12 and a connecting hook 13;

[0024] The second connecting seat 12 is installed on the upper side of the annular frame 7, and the connecting hook 13 is connected to one end of the second connecting seat 12;

[0025] It should be noted that during use, the furnace body 3 is fixed at the front end of the rotating frame 2, and the rotating frame 2 is rotatably connected to the upper side of the base frame 1. During use, the operator can cooperate with the four self-locking universal wheels 14 to move the position of the furnace body 3. When the feeder 4 needs to be picked up and hung, the base frame 1 can be moved between the annular frame 7 and the traction device 10 by moving the handrail 16, and then the hydraulic push rod 11 is controlled to operate, so that the rotating frame 2 can be moved to rotate and drive the furnace body 3 from vertical to horizontal. At this time, the lifting ring 6 on the top of the first connecting seat 5 will be connected to the connecting hook 13, and the cylinder 9 on the top of the support seat 8 will operate, so as to push the base frame 1 to move, so that the feeder can be separated from the furnace body 3. At the same time, the traction device 10 is connected to the base frame 1 by cooperating with the pull hook and the pull ring 15, and the traction device 10 is controlled to operate, so that the automatic picking and hanging operation of the feeder can be realized;

[0026] It should be emphasized that the furnace body 3 is connected to the rotating frame 2 through two fixing rings, so there is no need to worry about the furnace body 3 falling off during the rotation process, and because the technical solution adopts a horizontal extraction operation, the height requirement of the site is small;

[0027] A movable armrest 16 is installed on the upper side of the base frame 1, and the device position can be moved with the self-locking universal wheel 14;

[0028] A rotating armrest 17 is provided on the upper side of the rotating frame 2 , and an operator can also use the rotating armrest 17 to rotate the rotating frame 2 .

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
