Its main function is to compact and tamp the coal charged into the coke oven to improve the size and density of the coal, thereby ensuring the quality and output of coke. The tamping hammer is one of the core components of the equipment. The tamping hammer is usually composed of a long rod and a hammer head, and is made of high-strength alloy steel or other wear-resistant materials to ensure that it can withstand high pressure and frequent impacts without deformation or damage during the tamping process.

[0003] The existing tamping hammer for the coking tamping machine has a long rod and a hammer head which are integrally cast and formed, and can withstand the impact force during tamping.

[0004] However, after long-term use, the long rod and hammer head in the tamping hammer will be damaged and worn to varying degrees. Since the long rod and the hammer head are an integrated structure, when the tamping hammer needs to be replaced, the entire tamping hammer including the long rod and the hammer head must be replaced together, and it is impossible to replace one part alone. This will cause a waste of resources and increase maintenance costs. Utility Model Content

DETAILED DESCRIPTION

[0026] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] See also Figure 1-6 As shown, the utility model provides a tamping hammer for a coking tamping machine, comprising a long rod 1 and a hammer head 3, the lower end of the long rod 1 is fixedly connected with a convex connecting head 2, the upper surface of the hammer head 3 is fixedly connected with a connecting seat 4, a convex slot 41 is provided inside the connecting seat 4, and the convex connecting head 2 is slidably connected inside the convex slot 41, two groups of side threaded holes 42 are provided on both sides of the connecting seat 4, and the side threaded holes 42 are connected with the convex slot 41, the inner threads of the side threaded holes 42 are connected with locking bolts 5, and the convex connecting head 2 and the connecting seat 4 are fixed by the locking bolts 5, a plurality of groups of upper threaded holes 43 are provided on the upper surface of the connecting seat 4, and the upper threaded holes 43 are connected with the convex slot 41, half of the upper threaded holes 43 are connected with fixing bolts 6 for limiting the vertical position of the convex connecting head 2, and the inner threads of the other half of the upper threaded holes 43 are connected with elastic rods 7;

[0028] The utility model connects the hammer head 3 and the long rod 1 through the convex connector 2 and the connecting seat 4, and sets the hammer head 3 and the long rod 1 as a detachable structure, which is convenient for subsequent maintenance and replacement of the hammer head 3 or the long rod 1;

[0029] When installing the hammer head 3, it is only necessary to insert the convex connector 2 into the convex slot 41, and then limit the position of the convex connector 2 by the locking bolt 5 and the fixing bolt 6 to ensure that it is stable and reliable during operation; the elastic rod 7 can absorb and weaken part of the impact force generated by the hammer head 3, thereby reducing the impact on the fixing bolt 6 and protecting the fixing bolt 6.

[0030] Furthermore, both sides of the male connector 2 are provided with side grooves 21, and both ends of the side grooves 21 are provided with movable grooves 211. The end of the locking bolt 5 passes through the side threaded hole 42 and abuts against the inner wall of the movable groove 211; after the male connector 2 is inserted into the male slot 41, the locking bolt 5 is screwed into the side threaded hole 42, and its end abuts against the inside of the movable groove 211. At this time, the left and right groups of locking bolts 5 respectively limit the left and right sides of the male connector 2, which can effectively prevent the male connector 2 from unnecessary lateral movement during use. When disassembling the hammer head 3, the locking bolts 5 can be gradually loosened, and the disassembly process is safer and controllable, reducing the possibility of accidents. Specifically: first remove the locking bolts 5 at the same end on both sides of the connecting seat 4, and then loosen the locking bolts 5 at the other end on both sides of the connecting seat 4 (no need to completely remove them, so that the locking bolts 5 and the movable groove 211 lose the abutment state). At this time, move the hammer head 3 to the end where the locking bolt 5 is not completely removed, and the locking bolt 5 slides inside the side groove 21 until it slides to the movable groove 211, and the hammer head 3 cannot move. At this time, it is necessary to ensure that the position where the hammer head 3 slides down has sufficient strength to receive it, and finally completely remove the locking bolt 5. The hammer head 3 can continue to move until it is completely separated from the convex connector 2. The purpose of doing this is that if the hammer head 3 is in an inclined state, the two sets of locking bolts 5 are completely removed at this time. The hammer head 3 will slide down quickly due to the loss of the position restriction of the locking bolt 5 and the influence of its own inclined state, which may cause a safety accident.

[0031] Furthermore, the vertical height of the side groove 21 is greater than the outer diameter of the locking bolt 5. The purpose of this arrangement is to facilitate the sliding of the locking bolt 5 inside the side groove 21; the vertical height of the movable groove 211 is greater than the vertical height of the side groove 21. The purpose of this arrangement is that the locking bolt 5 only serves to limit the left and right positions of the convex connector 2. When the hammer head 3 is tamping and hammering, the hammer head 3 will generate an impact force from bottom to top. At this time, the upper and lower sides of the end of the locking bolt 5 will not contact the upper and lower sides of the movable groove 211, thereby avoiding the locking bolt 5 from being affected by the impact force and extending the service life of the locking bolt 5.

[0032] Furthermore, both sides of the upper surface of the male connector 2 are provided with limit slots 22, and the ends of the fixing bolts 6 pass through the upper threaded holes 43 and abut against the inner walls of the limit slots 22; the convex slots 41 serve the purpose of upper and lower limit for the male connector 2. After the male connector 2 is assembled and disassembled many times, a gap will be generated between the male connector 2 and the convex slots 41. At this time, only relying on the convex slots 41 to limit the upper and lower positions of the male connector 2 will result in a poor fixing effect. Therefore, by abutting the fixing bolts 6 against the upper end of the male connector 2, the upper and lower limit of the male connector 2 can be effectively provided, thereby enhancing its structural stability.

[0033] Furthermore, the bottom of the male connector 2 and the male slot 41 are both trapezoidal structures. The trapezoidal structure can increase the surface area of ​​the connection, thereby enhancing the firmness of the connection, making it more difficult for the hammer head 3 to fall off or loosen. In addition, the trapezoidal structure can also reduce the friction between the hammer head 3 and the connecting seat 4, so that the hammer head 3 moves more smoothly during use, thereby improving work efficiency. Secondly, since the trapezoidal structure has clear positioning features, it is easier to align the male connector 2 and the male slot 41 during assembly, reducing the error during assembly and improving assembly efficiency.

[0034] Furthermore, the outer corner of the male connector 2 and the inner corner of the male slot 41 are both arc-shaped chamfers; the arc-shaped chamfers can reduce the stress concentration at the connection between the male connector 2 and the male slot 41, making the force distribution more uniform and reducing the risk of fracture or deformation caused by excessive local stress. In addition, the arc-shaped chamfers can also reduce the friction between the male connector 2 and the male slot 41, making the connection smoother.

[0035] When the locking cam 73 is in the state of being moved forward, the locking cam 731 of the locking cam 73 When the tamping hammer is tamping, part of the impact force generated by the hammer head 3 can be transmitted to the movable rod 73 through the rubber pad 732. After the movable rod 73 is subjected to the impact force, it presses the spring 74 upward and transmits part of the impact force to the spring 74. The spring 74 shakes, thereby absorbing and weakening the impact force. The purpose of this is to absorb and weaken part of the impact force generated by the hammer head 3, thereby reducing the impact force transmitted to the fixing bolt 6 and extending the service life of the fixing bolt 6; the rubber pad 732 can provide a soft cushion layer, so that the contact between the movable rod 73 and the limit groove 22 becomes soft, thereby reducing the wear caused by hard contact. In addition, the rubber pad 732 can also absorb and weaken the impact force transmitted, and transmit the remaining impact force to the movable rod 73.

[0036] Working principle: When installing the hammer head 3, insert the connecting seat 4 into the outer side of the convex connecting head 2 through the convex slot 41. After being inserted into place, use the locking bolt 5 to screw into the side threaded hole 42 so that the end of the locking bolt 5 abuts against the inner wall of the movable groove 211. Use the fixing bolt 6 to screw into the upper threaded hole 43 so that the end of the fixing bolt 6 abuts against the inner wall of the limiting groove 22. At this time, the connecting seat 4 and the convex connecting head 2 are fixed by the locking bolt 5. Then screw the threaded sleeve 71 into the remaining upper threaded hole 43 through the hexagonal fixing buckle 72. When the rubber pad 732 contacts the limiting groove 22, continue to screw the hexagonal fixing buckle 72. At this time, the movable rod 73 will slide upward relative to the threaded sleeve 71, thereby compressing the spring 74. While the spring 74 is compressed, the elastic force generated can make the rubber pad 732 firmly fit the top of the inner wall of the limiting groove 22;

[0037] When the coking tamping machine drives the tamping hammer to perform reciprocating hammering, part of the impact force generated by the hammer head 3 is transmitted to the movable rod 73 through the rubber pad 732. The movable rod 73 then transmits part of the impact force to the spring 74, and the spring 74 undergoes elastic deformation, thereby absorbing the transmitted impact force, sharing the impact force, and reducing the impact force received by the fixing bolt 6.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
