Description

Technical Field

[0001] This utility model relates to the field of tamping equipment technology, and in particular to a complete set of tamping units for coke ovens. Background Technology

[0002] A tamping coke oven requires a matching tamping machine to tamp the coal powder into coal cakes. Then, the coal loading car loads the coal cakes into the coke oven carbonization chamber. Traditional tamping machines require manual operation of the control buttons on the mechanical equipment to tamp the coal cakes. During the tamping operation, the operator needs to concentrate and tamp the coal cakes according to the number of tamping and feeding operations required by the operating procedures. The tamping machine unit is an important part of the tamping operation.

[0003] However, traditional tamping units for coke ovens cannot effectively count the number of tamping blows by the tamping hammer during operation, which directly affects the quantitative management of tamping work and consequently has an adverse impact on the accuracy of the tamping unit's work. The tamping unit lacks precise position control during operation, and the position of the tamping hammer cannot be clearly confirmed after the coal cake is tamped, which seriously interferes with the accuracy of the tamping unit's positioning and creates safety hazards for subsequent work. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-5 As shown, a complete set of tamping units for coke ovens includes a tamping box 1 and a frame 2. The frame 2 is fixedly installed on the outside of the tamping box 1. A lifting cylinder 3 is fixedly installed on the top of the frame 2. A drive rod 4 is connected to the output end of the lifting cylinder 3. A lifting frame 5 is connected to the bottom end of the drive rod 4. A tamping hammer 6 is connected to the bottom of the lifting frame 5. A connecting frame 7 is fixedly installed on the outside of the frame 2. A connecting shaft 8 is rotatably connected to the inside of the connecting frame 7. An elastic guide wheel 9 adapted to the lifting frame 5 is sleeved on the outer surface of the connecting shaft 8. A counting limit structure 10 is connected to the outside of the connecting frame 7.

[0025] In this embodiment, the counting limit structure 10 includes a connecting frame 11, a drive shaft 12, a half gear 13, a limit sleeve 14, and a lifting frame 15. The connecting frame 11 is fixedly installed on the outside of the connecting frame 7. The drive shaft 12 is connected to the connecting shaft 8. The half gear 13 is sleeved on the outer surface of the drive shaft 12. The limit sleeve 14 is fixed on the inner side of the connecting frame 11. The lifting frame 15 passes through the interior of the limit sleeve 14.

[0026] The drive shaft 12 rotates together with the connecting shaft 8, which can drive the half gear 13 to rotate synchronously. The half gear 13 meshes with the rack plate 16 to provide power for the lifting of the lifting frame 15. The limit sleeve 14 limits the lifting of the lifting frame 15.

[0027] In this embodiment, a rack plate 16 adapted to the half gear 13 is fixedly installed on the outer surface of the lifting frame 15, and a trigger head 17 is connected to the bottom end of the lifting frame 15, and a trigger switch 18 is connected to the bottom of the connecting frame 11.

[0028] The lifting frame 15 moves up and down inside the connecting frame 11, which can drive the trigger head 17 to contact the trigger switch 18. At the same time as the trigger head 17 contacts the trigger switch 18, it counts the number of times the tamping hammer 6 of the tamping unit is used.

[0029] In this embodiment, a guide rod 19 is connected between the lifting frame 15 and the connecting frame 11. A return spring 20 is sleeved on the outer side of the guide rod 19. The lifting frame 15 is movably connected to the connecting frame 11 through the guide rod 19 and the return spring 20.

[0030] When the half gear 13 rotates and no longer contacts the rack plate 16, the lifting frame 15 moves relative to the connecting frame 11 through the guide rod 19 and the reset spring 20. The lifting frame 15 drives the trigger head 17 to separate from the trigger switch 18 for reset.

[0031] In this embodiment, a first connecting column 21 is fixedly installed at the bottom of the lifting frame 5, and a second connecting column 22 is fixedly installed at the bottom of the frame 2. The first connecting column 21 and the second connecting column 22 are located in the same axial direction. An upper limit seat 23 is fixedly installed at the end of the first connecting column 21, and a lower limit seat 24 is fixedly installed at the end of the second connecting column 22. The upper limit seat 23 and the lower limit seat 24 are compatible.

[0032] During the descent of the lifting frame 5, the first connecting column 21 drives the upper limit seat 23 to move closer to the lower limit seat 24 on the second connecting column 22. When the upper limit seat 23 and the lower limit seat 24 are combined, the limit is realized during the operation of the tamping unit, which facilitates the confirmation of the tamping hammer 6 in place after the coal cake tamping is completed.

[0033] In this embodiment, the outer surface of the elastic guide wheel 9 is provided with a guide wheel groove that is compatible with the lifting frame 5, and the lifting frame 5 moves up and down inside the elastic guide wheel 9.

[0034] During the lifting process, the lifting frame 5 comes into contact with the elastic guide wheel 9, which can guide the lifting process of the lifting frame 5 and ensure that the lifting frame 5 lifts and lowers along the prescribed path.

[0035] In this embodiment, the outer contour of the tamping hammer 6 is adapted to the receiving cavity of the tamping box 1, and the lifting height of the lifting frame 5 is the same as the height of the tamping box 1.

[0036] The matching of the tamping hammer 6 with the receiving cavity of the tamping box 1 ensures that the tamping hammer 6 can completely tamp the tamping box 1. The lifting height of the lifting frame 5 is the same as the height of the tamping box 1, which ensures that the tamping hammer 6 can reach the bottom of the tamping box 1.

[0037] It should be noted that this utility model is a complete set of tamping units for coke ovens. In use, the coal cake material to be tamped is put into the tamping box 1, and the lifting cylinder 3 is activated. The lifting cylinder 3 drives the lifting frame 5 via the drive rod 4, which in turn drives the tamping hammer 6 on the lifting frame 5 to tamp the coal cake material. During the lifting process, the lifting frame 5 contacts the elastic guide wheel 9, which guides the lifting process and ensures that the lifting frame 5 lifts and lowers along a predetermined path. The transmission shaft 12 rotates together with the connecting shaft 8, which drives the half gear 13 to rotate synchronously. The half gear 13 meshes with the rack plate 16 to provide power for the lifting of the lifting frame 15. The limiting sleeve 14 limits the lifting of the lifting frame 15. The lifting frame 15 is connected to the connecting frame 11. The inner side is raised and lowered, which can drive the trigger head 17 to contact the trigger switch 18. At the same time, the trigger head 17 and the trigger switch 18 are in contact and counting can be performed to count the number of times the tamping hammer 6 of the tamping unit is tamped. When the half gear 13 rotates and no longer contacts the rack plate 16, the lifting frame 15 moves relative to the connecting frame 11 through the guide rod 19 and the return spring 20. The lifting frame 15 drives the trigger head 17 to separate from the trigger switch 18 for reset. During the descent of the lifting frame 5, the first connecting column 21 drives the upper limit seat 23 to move closer to the lower limit seat 24 on the second connecting column 22. When the upper limit seat 23 and the lower limit seat 24 are engaged, the limit is achieved during the operation of the tamping unit, which facilitates the confirmation of the tamping hammer 6 in place after the coal cake tamping is completed.
