[0034] like Figures 1 to 5 Combined with Figure 6 As shown, the coke oven lifting device of the utility model includes: a lifting claw, a trolley plate 1, and a hoisting mechanism 9. A moving wheel 13 is rotatably provided at the lower part of the trolley plate 1. The moving wheel 13 rolls with a track (not shown), so that the moving wheel 13 rotates under the drive of a driving motor (not shown), thereby horizontally moving the trolley plate 1 along the track; the hoisting mechanism 9 is fixed on the upper surface of the trolley plate 1, and the hoisting mechanism 9 includes a hoisting drum 10, a wire rope 14, a reduction mechanism 15, and a motor 16. The wire rope 14 is wound on the hoisting drum 10, and the hoisting drum 10 is transmission-connected to the motor 16 through the reduction mechanism 15. Under the drive of the motor 16, the hoisting drum 10 rolls up or releases the wire rope 14; the lifting claw is slidably assembled under the trolley plate 1 through an up and down sliding mechanism.

[0035] Specifically, the lifting claw of the coke oven lifting equipment of the utility model includes: a circular base plate 2; three clamping claws 3 evenly arranged on the lower surface of the base plate 2 along the circumferential direction of the base plate 2, the upper end of each clamping claw 3 is set on the lower surface of the base plate 2 and can slide back and forth along the radial direction of the base plate 2, and the lower end of each clamping claw 3 has an inwardly extending hook claw 5, that is, each hook claw 5 extends toward the center of the base plate 2; a lifting hook 6, the lifting hook 6 is located between the three clamping claws 3, the upper part of the lifting hook 6 has a hook body 7 for connecting the wire rope 14, and the lower part of the lifting hook 6 is respectively connected to the three clamping claws 3 through three connecting rods 8, one end of each connecting rod 8 is hinged to the lifting hook 6, and the other end is hinged to the lower part of the corresponding clamping claw 3.

[0036] As a specific embodiment, the above-mentioned up-and-down sliding mechanism for slidingly assembling the lifting claw under the trolley plate 1 includes: three guide holes 11 opened through the bottom plate 2, and the three guide holes 11 are evenly arranged along the circumferential direction of the bottom plate 2; three guide columns 12 fixed on the lower surface of the trolley plate 1, and the three guide columns 12 are arranged to correspond to the three guide holes 11 one by one, and the free ends of the guide columns 12 extend into the corresponding guide holes 11 and slide with the guide holes 11. Thus, through the sliding cooperation between the guide columns 12 and the guide holes 11, the trolley plate 1 and the bottom plate 2 of the lifting claw are slidably assembled up and down.

[0037] Optionally, as another specific embodiment, the above-mentioned up-and-down sliding mechanism for slidingly assembling the lifting claw under the trolley plate 1 includes: three guide posts fixed on the upper surface of the bottom plate 2, and the three guide posts are evenly arranged along the circumferential direction of the bottom plate 2; three guide holes opened through the trolley plate 1, and the three guide holes are set to correspond to the three guide posts one by one, and the free ends of the guide posts 12 extend into the corresponding guide holes 11 and slide with the guide holes 11. Thus, through the sliding cooperation of the guide posts and the guide holes, the trolley plate 1 and the bottom plate 2 of the lifting claw are slidably assembled up and down.

[0038] Although in the above-mentioned embodiment of the up-and-down sliding mechanism for slidingly assembling the lifting claw under the trolley plate 1, the trolley plate 1 and the bottom plate 2 of the lifting claw are slidably assembled up and down through the sliding cooperation of the guide column and the guide hole, as other embodiments, other guide structures such as a slider groove structure can also be used to realize the up-and-down sliding assembly of the trolley plate 1 and the bottom plate 2.

[0039] As a specific embodiment, the radial reciprocating sliding of the clamping claw 3 along the bottom plate 2 can be realized as follows: three T-slots (slots with a T-shaped cross section) are radially opened on the lower surface of the bottom plate 2, and each T-slot is a through slot at the outer peripheral surface of the bottom plate 2; a T-head that slides with the T-slot is provided at the upper end of each clamping claw 3, and the T-head is inserted into the T-slot from the outer peripheral surface of the bottom plate 2, so that the upper end of each clamping claw 3 is slidably arranged on the lower surface of the bottom plate 2 through the sliding cooperation between the T-head and the corresponding T-slot; a linear drive mechanism 4 is arranged between each clamping claw 3 and the bottom plate 2 to drive the clamping claw 3 to slide reciprocatingly along the radial direction of the bottom plate 2, and preferably the linear drive mechanism 4 is a hydraulic cylinder or a pneumatic cylinder. Of course, as other embodiments, the linear drive mechanism can also be an electric cylinder, etc.

[0040] More specifically, the cylinder body of the hydraulic cylinder or the pneumatic cylinder is integrated at the upper end of the clamping claw 3, wherein the T-shaped head at the upper end of the clamping claw 3 is opened inside to form the oil chamber of the hydraulic cylinder or the cylinder of the pneumatic cylinder, and the piston rod of the hydraulic cylinder or the pneumatic cylinder is fixed on the base plate 2, and the piston of the piston rod extends into the oil chamber or the cylinder to divide the oil chamber or the cylinder into a rod chamber and a rodless chamber. When it is necessary to drive the clamping claw 3 to slide back and forth along the radial direction of the base plate 2, the rod chamber and the rodless chamber of the hydraulic cylinder or the pneumatic cylinder alternately fill and return oil or intake and exhaust air, thereby driving the T-shaped head of the clamping claw 3 to reciprocate along the T-shaped groove of the base plate 2, thereby making the clamping claw 3 slide back and forth along the radial direction of the base plate 2, so that the three clamping claws 3 move away from or approach each other. Preferably, the three hydraulic cylinders or pneumatic cylinders arranged between the three clamping claws 3 and the base plate 2 move synchronously through a matching synchronous oil circuit or air circuit system.

[0041] Although in the above-mentioned embodiment in which the clamping claw 3 slides radially back and forth along the base plate 2, the sliding assembly between the clamping claw 3 and the base plate 2 is achieved by sliding cooperation between the T-slot opened on the lower surface of the base plate 2 and the T-head set at the upper end of the clamping claw 3, as other embodiments, other forms of sliding structures can also be used to perform the sliding assembly between the clamping claw 3 and the base plate 2.

[0042] Although in the above-mentioned embodiment of the linear drive mechanism, the cylinder body of the hydraulic cylinder or the pneumatic cylinder is integrated at the upper end of the clamping claw 3, and the piston rod of the hydraulic cylinder or the pneumatic cylinder is fixed on the base plate 2, as other embodiments, the hydraulic cylinder or the pneumatic cylinder may also be an independent structure, with its cylinder body fixed on the clamping claw 3 and its piston rod fixed on the base plate 2.

[0043] The working principle and process of the coke oven lifting device and its lifting claw of the utility model are as follows:

[0044] When the coke oven 17 needs to be lifted, the trolley plate 1 cooperates with the track, and the trolley plate 1 moves horizontally on the track under the drive of the driving motor, and the trolley plate 1 drives the bottom plate 2 slidably mounted thereunder and the three clamping claws 3 slidably arranged on the lower surface of the bottom plate 2 to move to the top of the coke oven 17, so that the circumference of the bottom plate 2 is roughly coaxial with the outer circumference of the mouth of the coke oven 17; the hydraulic cylinder or pneumatic cylinder arranged between each clamping claw 3 and the bottom plate 2 drives the three clamping claws 3 to move away from each other, so that the radius of the circle where the three clamping claws 3 are located is larger than the outer ring radius of the outer flange 18 of the outer circumference of the mouth of the coke oven 17; the wire rope 14 is loosened through the hoisting drum 10 of the hoisting mechanism 9, thereby connecting the lifting hook 6 connected to the wire rope 14 and then the connecting rod 8, The clamping claws 3 and the bottom plate 2 descend due to their own weight, thereby lowering the bottom plate 2, and when the hook claws 5 at the lower ends of the clamping claws 3 move below the outer flange 18 of the mouth of the coke oven 17, the loosening of the wire rope 14 is stopped; thereafter, the hydraulic cylinder or pneumatic cylinder arranged between each clamping claw 3 and the bottom plate 2 drives the three clamping claws 3 to approach each other, so that the three hook claws 5 are stably engaged with the outer flange 18 outside the mouth of the coke oven 17; finally, the wire rope 14 is rolled up by the hoisting drum 10 of the hoisting mechanism 9, and the lifting hook 6 is pulled inwardly into the lower parts of the three clamping claws 3 through the connecting rod 8, so that the three hook claws 5 gather inwardly, press the outer peripheral surface of the coke oven 17 and reliably and firmly hook the outer flange 18, thereby reliably clamping the coke oven 17 and lifting the coke oven 17.

[0045] In summary, in the process of lifting the coke oven 17 using the coke oven lifting device and its lifting claw of the utility model, the track guides the trolley plate 1 horizontally, which can ensure that the coke oven 17 moves smoothly in the horizontal direction; the bottom plate 2 is located below the trolley plate 1 and is assembled with the trolley plate 1 by sliding cooperation of the guide column 12 and the guide hole 11, thereby realizing the positioning of the bottom plate 2 and the lifted coke oven 17 in the vertical direction, preventing the coke oven 17 from shaking in the vertical direction, and ensuring that the coke oven 17 moves smoothly in the vertical direction. Therefore, the coke oven lifting device and its lifting claw provided by the utility model can simultaneously realize the smooth lifting of the coke oven in the horizontal and vertical directions during the process of lifting the coke oven 17, avoiding shaking during the lifting process, and the lifting process is smooth and safe, which fundamentally eliminates the problem of difficulty in accurately lifting the coke oven and easy shaking during the lifting process in the prior art.

[0046] Furthermore, in the coke oven lifting device and its lifting claw of the utility model, the three clamping claws 3 are evenly arranged on the circular surface. When the clamping claws 3 clamp the coke oven 17, it can be ensured that the three clamping claws 3 are evenly stressed, thereby improving the stability of the clamping claws 3 clamping the coke oven 17; the upper part of the clamping claw 3 is slidably arranged on the lower surface of the base plate 2, and a hydraulic cylinder or a pneumatic cylinder for driving the clamping claw 3 to move is provided between each clamping claw 3 and the base plate 2. Before lifting the coke oven 17, the hydraulic cylinder or the pneumatic cylinder drives each clamping claw 3 away from each other. When the lifting device is moved to an appropriate position, the hydraulic cylinder or the pneumatic cylinder drives each clamping claw 3 to approach each other to clamp the coke oven 17; the lower part of the clamping claw 3 has an inwardly extending hook claw 5, which can hook the outer flange 18 on the outer periphery of the mouth of the coke oven 17, thereby improving the stability of the clamping of the coke oven 17. Therefore, the coke oven lifting device and the lifting claw thereof provided by the utility model can effectively improve the accuracy, safety and reliability of lifting the coke oven during the process of lifting the coke oven 17 .
