It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Figures 1 and 2, a tuyere cover lifting tool includes: a connecting device 1 for connecting the lifting device; two auxiliary arms 2 hinged with the connecting device 1; two main arms bent in the middle and set back 3. The upper part of the main arm 3 is hinged to the auxiliary arm 2; the balance part 4 is hinged to the bend of the two main arms 3; and the hooking part 5 is connected to the lower part of the main arm 3. The hoisting tool of the tuyere cover of the utility model can be hooked to the edge of the small end of the tuyere cover and the blank of the tuyere cover, and can conveniently, safely and stably place the small end of the tuyere cover and the blank of the tuyere cover upwards and vertically, reducing operation Labor intensity of personnel.

Specifically, the connecting device 1 is used for connecting the hook of the lifting device. The two auxiliary arms 2 are made by cutting the steel plates into long strips. The balance part 4 is made by cutting steel plates; the two main arms 3 are made by bending the steel bars in the middle, and the upper and lower parts of the main arms 3 are bent at an obtuse angle; the hooking part 5 is two long iron blocks. One ends of the two auxiliary arms 2 are hinged to the lower part of the connecting device 1 through pin shafts; the other ends of the two auxiliary arms 2 are respectively hinged to the upper ends of the two main arms 3 through pin shafts. The two ends of the balance part 4 are provided with hinge shafts to respectively hinge the bending points of the two main arms 3 so that the two main arms 3 are arranged facing away, that is, the openings of the obtuse angles of the two main arms 3 face opposite directions. The lower end of the main arm 3 is welded with a hook joint 5 for hooking the edge of the tuyere sleeve or the blank of the tuyere sleeve.

When in use, connect the connecting device 1 to the hook of the lifting device; put the hooking part 5 at the lower end of the main arm 3 from the small end into the through hole of the tuyere cover or the blank of the tuyere cover, and hook the hooking part 5 to the small end. Slowly raise the hook, and drive the upper parts of the two main arms 3 to merge toward the center through the connecting device 1 and the auxiliary arm 2, so that the lower parts of the two main arms 3 are separated to both sides, and then the hooking part 5 is hooked. On the sidewall of the small end, the front end of the hooking part 5 is pressed against the inner wall of the tuyere sleeve or the blank of the tuyere sleeve, and finally the small end of the tuyere sleeve or the blank of the tuyere sleeve is lifted up and vertically. During the hoisting process, the balance part 4 can be moved to adjust the relative positions of the hinge shafts of the two arms to adjust the positions of the two hooking parts 5, so that the hooking parts 5 at the lower ends of the two main arms 3 can be hooked with the ribs It is firm, and can prevent the tuyere sleeve or the blank of the tuyere sleeve from tilting.

Further, as shown in FIGS. 1 and 2 , a connecting rib 6 is also included, and the connecting rib 6 connects the upper part and the lower part of the main arm 3 . The tuyere cover or the blank of the tuyere cover is heavy, and the upper and lower parts of the main arm 3 are connected through the connecting rib 6, so that the connecting rib 6 and the upper and lower parts of the main arm 3 form a triangle, which has better stability and prolongs the service life. Specifically, the connecting rib 6 is a steel bar, and one end of the connecting rib 6 is welded on the upper end of the main arm 3 , and the other end is welded on the lower end of the main arm 3 and is jointly welded with the hook joint 5 .

Further, the balance part 4 is a balance board, and the two ends of the balance board are respectively hinged to the bending places of the two main arms 3 .

Further, as shown in FIGS. 3 and 4 , the abutting end of the hooking portion 5 is pointed or arc-shaped. The front end of the hooking portion 5 is a butting end, which is used to tighten the inner wall of the tuyere sleeve or the blank of the tuyere sleeve. The top-to-end is made into a pointed or arc shape to better fit the inner wall, and the hook connection is more stable, so that the tuyere sleeve or the blank of the tuyere sleeve is not easy to shake and prevents it from falling.

Further, as shown in FIGS. 1 and 2 , an anti-loosening rod 7 is also included. One end of the anti-loosening rod 7 is hinged to the auxiliary arm 2 , and the other end is hooked to another auxiliary arm 2 . The anti-off rod 7 prevents the operator from pulling the main arm 3 or the auxiliary arm 2 to make the tuyere cover or the blank of the tuyere cover fall off during the lifting process. Specifically, the anti-off rod 7 is a long strip of iron, one end of the anti-off rod 7 is hinged on a secondary arm 2 through a pin, and the other end of the anti-off rod 7 is bent into a hook for hooking another pair of arms. arm2.

Further, as shown in FIGS. 1 and 2 , the auxiliary arm 2 is provided with a plurality of slots 8 for locking one end of the anti-loosening rod 7 . This makes the hooking between the anti-loosening rod 7 and the auxiliary arm 2 more firm. Specifically, a row of holes cooperating with the hooks of the anti-off rod 7 can be drilled along the auxiliary arm 2 as the slot 8 .

Further, as shown in Figures 1 and 2, the connecting device 1 is a connecting plate provided with lifting holes, and the two ends of the connecting plate are respectively hinged to two sub-arms 2 . The connecting device 1 provided with lifting holes can be conveniently matched with different lifting devices. Simultaneously, the hinge connection between the connecting plate and the auxiliary arm 2 makes the movement direction of the auxiliary arm 2 fixed, preventing the auxiliary arm 2 from shaking and causing the workpiece to fall off.

Further, the main arm 3 forms a labor-saving lever with the hinge point of the main arm 3 and the auxiliary arm 2 as the force application point, the hinge point of the main arm 3 and the balance part 4 as the fulcrum, and the hooking part 5 as the resistance point. The force of hooking part 5 hooking the tuyere cover or the blank of the tuyere cover is greater, and the hooking is more stable. Specifically, the length from the bending position of the main arm 3 to the lower end of the main arm 3 is shorter than the length from the bending position of the main arm 3 to the upper end of the main arm 3 .

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model should be included in the utility model. within the scope of protection.
