[0034] The driving and adjusting mechanism is arranged above the support frame 1. The driving and adjusting mechanism includes a front crank arm 6, a rear crank arm 7, a telescopic member 8 and a flexible connecting member 9 with adjustable length. One end of the front crank arm 6 is connected to the front claw 2 through a front connecting rod 10, and one end of the rear crank arm 7 is connected to the rear claw 3 through a rear connecting rod 11. Two ends of the telescopic member 8 are respectively connected to the other end of the rear crank arm 7 and the support frame 1, and two ends of the flexible connecting member 9 are respectively connected to the other ends of the front crank arm 6 and the rear crank arm 7.

[0035] Specifically, to solve the problem that the front claw 2 and the rear claw 3 of the existing ladle cover adding and removing device cannot be adjusted separately according to the situation of the ladle cover 20, and the existing ladle cover adding and removing equipment cannot be used frequently due to the uneven heights of the front connecting column 21 and the rear connecting column 22 of the ladle cover 20; the ladle cover adding and removing device provided by the present utility model can drive the front claw 2 and the rear claw 3 to lift through the setting of the driving and adjusting mechanism and enable the front claw 2 and the rear claw 3 to independently adjust the lifting height. The driving and adjusting mechanism drives the rear crank arm 7 to rotate through the telescopic movement of the telescopic member 8, and then drives the rear claw 3 to lift. At the same time, due to the setting of the flexible connecting member 9 with adjustable length, when the rear crank arm 7 rotates, it can drive the front crank arm 6 to rotate, and then drive the front claw 2 to lift. A support arm 4 is connected to the upper side of the front claw 2, and a bending part is arranged at the upper end of the support arm 4. After the front claw 2 is lifted, the bending part 5 passes through the support frame 1 and is exposed above the support frame 1.

In this way, the lifting height of the rear claw 3 can be further adjusted by adjusting the telescopic movement of the telescopic member 8, and due to the adjustable length of the flexible connecting member 9, the length of the flexible connecting member 9 can also be adjusted so that the front claw 2 does not lift or the lifting height of the front claw 2 is less than that of the rear claw 3 when the rear claw 3 lifts; thus, the effect that the lifting heights of the front claw 2 and the rear claw 3 of the ladle cover adding and removing device can be independently adjusted is achieved, and it can flexibly cope with the uneven heights of the front connecting column 21 and the rear connecting column 22 on the upper side of the ladle cover 20; the ladle cover adding and removing device has a simple structure, is convenient to maintain, has a flexible adjustment method, can improve the success rate of adding and removing the ladle cover 20, thereby improving work efficiency, reducing the labor intensity of workers, and increasing the safety of operators.

[0036] Optionally, it further includes a plurality of gaskets 12, and the gaskets 12 can be padded between the bending part above the support frame 1 and the support frame 1.

[0037] Specifically, the limiting member can be a plurality of gaskets 12, and the number of gaskets 12 padded can determine the lifting height of the front claw 2.

[0038] Optionally, it further includes a lifting rope 13, and the lifting rope 13 is used to be sleeved on the bending part and is used to lift the front claw 2.

[0039] Specifically, the bent portion and the support arm 4 form an L shape. The lifting rope 13 can also be sleeved on the bent portion, and then the lifting equipment is used to lift the front claw 2 through the lifting rope 13 to realize the lifting of the front claw 2. Then, the gasket 12 is inserted to adjust the lifting height of the front claw 2.

[0040] Optionally, the flexible connecting portion includes a steel wire rope.

[0041] Specifically, the flexible connecting portion can adopt a steel wire rope or a connecting chain, etc.

[0048] Specifically, the front claw 2 and the rear claw 3 can adopt existing structures. The first clamping groove 18 and the second clamping groove 19 on the upper sides of the front claw 2 and the rear claw 3 can respectively clamp the front connecting column 21 and the rear connecting column 22 on the ladle cover 20 after the ladle cover 20 moves into place, improving the stability of the fixation of the ladle cover 20 after the cover is removed; further, the operations of removing and covering the ladle cover 20 both depend on the movement of the ladle. Similar to the traditional ladle cover adding and removing device, after adjusting the lifting height and position of the front claw 2 and the rear claw 3, this ladle cover adding and removing device no longer operates, and both the cover removal and covering are completed by the movement of the ladle. This technology is the same as the traditional ladle cover adding and removing device and will not be elaborated here.

[0049] Optionally, it further includes a hydraulic station 23 and an operation box 24. The telescopic member 8 is a hydraulic cylinder, and the hydraulic cylinder is connected to the hydraulic station 23 through a hydraulic pipe 25. The operation box 24 is used to operate the hydraulic station 23.

[0050] Specifically, the operation of the hydraulic station 23 is controlled through the operation box 24, and then the telescopic movement of the hydraulic cylinder is controlled. The lifting and lowering operations of the rear claw 3 and the front claw 2 are driven by the telescopic movement of the hydraulic cylinder.

[0051] Optionally, a front hinge support 26 and a rear hinge support 27 are provided below the bottom surface of the support frame 1. The rear ends of the front claw 2 and the rear claw 3 are respectively rotatably connected to the front hinge support 26 and the rear hinge support 27.

[0054] In this embodiment, two front hinge ears 28 and two rear hinge ears 29 are respectively provided, and one support ear 30 is provided. The two front crank arms 6 are rotatably connected to the two front hinge ears 28 through a front rotating shaft, and the two rear crank arms 7 are rotatably connected to the two rear hinge ears 29 through a rear rotating shaft.

[0055] In summary, when the ladle cover lifting and removing device provided by the present utility model is in use, it has the following four working modes:

[0056] 1. As Figure 5 shown, the first working mode is to start the hydraulic station 23 and control the hydraulic cylinder to actuate. When the hydraulic cylinder extends, the front claw 2 and the rear claw 3 are lifted synchronously. Correspondingly, when the hydraulic cylinder retracts, the front claw 2 and the rear claw 3 fall synchronously.

[0057] 2. As Figure 6 shown, the second working mode is to lift the front claw 2 and the rear claw 3 simultaneously by extending the hydraulic cylinder, then pad a set number of gaskets 12 between the lower side of the bending part 5 and the upper side of the support frame 1 to limit the front claw 2, and then control the hydraulic cylinder to retract to make the rear claw 3 fall. Finally, adjust the length of the flexible connection member 9 to make the flexible connection member 9 tightened.

[0058] 3. As Figure 7As shown, the third working mode is to sleuth the lifting rope 13 on the bending part 5, use the lifting equipment to lift the front claw 2 through the lifting rope 13, then pad a set number of gaskets 12 between the lower side of the bending part 5 and the upper side of the support frame 1 to limit the front claw 2, and then adjust the length of the flexible connection member 9 to make the flexible connection member 9 tightened.

[0059] 4. As Figure 8 shown, the fourth working mode lifts the front claw 2 in the way of the second or third working mode, removes the gasket 12, then loosens the flexible connection member 9, that is, adjusts the length of the flexible connection member 9 to be longer, then controls the hydraulic cylinder to extend to drive the rear claw 3 to lift. After the adjustment is completed, lower the front claw 2, and finally adjust the length of the flexible connection member 9 to make the flexible connection member 9 tightened.

[0060] The embodiments of the present invention have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
