Detailed Description

For further understanding of the present invention, embodiments of the present invention are described below with reference to examples, but it should be understood that these descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the present invention.

The embodiment of the utility model discloses a device that is used for interior end bucket of hot chamber to transport temporarily, as shown in figure 1, include: the device comprises a support flange 3, a fixed jaw 1, a movable jaw 5 and a lifting lug 4;

the support flange 3 is fixedly connected with a fixed jaw 1 and a movable jaw 5, and the connection mode can be welding or other fixed connection;

specifically, for the convenience of placement and removal, it is preferable to include 1 fixed jaw 1 and 2 movable jaws 5. The fixed clamping jaws 1 and the movable clamping jaws 5 are uniformly distributed on the supporting flange 3.

The outer edges of the fixed clamping jaw 1 and the movable clamping jaw 5 are on the same circumference;

the length of the fixed jaw 1 is preferably 250-300 mm, and more preferably 280mm; the length of the movable jaw 5 is preferably 250 to 300mm, and more preferably 280mm. The fixed jaw 1 and the movable jaw 5 are equal in length.

The diameter of the excircle of the fixed jaw 1 and the movable jaw 5 when the fixed jaw and the movable jaw are unfolded is within the range of 410-415 mm, so that the end barrel can still be safely lifted when the transfer device is tightly attached to one side of the end barrel due to remote operation errors.

The supporting flange 3 is provided with a hole, the lifting lug 4 penetrates through the hole to realize a lifting function, and the transfer work of the end barrel is completed by matching a hot chamber crane and a master-slave manipulator when the lifting lug is used; preferably, 4 holes are symmetrically arranged on the supporting flange.

The movable clamping jaw 5 comprises a limiting plate 6 and a movable section 7, the limiting plate 6 is connected with the supporting flange 3, the movable section 7 is hinged with the limiting plate 6 through a movable joint 8, the root of the movable joint 8 is in a fillet shape, the fillet is upward, and the movable section is turned over within the range of 0-90 degrees; the limiting plate 6 limits the movable section 7 from falling to the supporting flange 3 due to excessive upturning.
