[0002] The quality of tamped coal cakes directly affects coke oven production. Coking plants require tamping equipment to produce coal cakes with uniform density, high density, and high strength. The increasing scale and intelligence of tamping equipment also necessitates solutions to problems such as low and uneven coal cake density, which easily leads to cake collapse and coal loss, and the difficulty of effectively controlling coal cake quality with current tamping machines. Therefore, further improvements to tamping equipment are needed. In short, developing high-performance tamping equipment has become a crucial task for tamping equipment manufacturers.

[0003] According to patent document CN116004258A, a tamping hammer for preparing uniform density coal cakes is disclosed, including a tamping rod and a tamping hammer head. The bottom of the tamping rod is provided with an adjustable angle tamping hammer head. The tamping rod has a hollow structure, and the tamping hammer head is a trapezoidal body. Several guide sleeves are fixed inside the tamping rod from top to bottom. A power rod is provided through the guide sleeves. The top of the power rod extends to the top of the tamping rod and is connected to a power rod driver for driving the power rod to move up and down. A rotating shaft is rotatably installed on one side wall at the bottom of the tamping rod. The front and rear end faces of the top center of the tamping hammer head are rotatably connected to an L-shaped coal leveling rod.

In the event of an accident or when the tamping hammer malfunctions, the hammer tamping machine cannot continue to work and needs to be stopped for repair. It can only be used again after the fault is completely eliminated, which greatly affects production efficiency and has poor shock absorption effect. Utility Model Content

Spring three further enhances the stability and shock absorption performance of the hammer head during tamping. This clamping mechanism not only improves tamping efficiency but also ensures the uniformity and high density of the tamping quality, meeting the high requirements of coking plants for coal cake quality.

[0025] Please see Figure 1 , Figure 3 and Figure 4The clamping mechanism 3 includes a mounting frame 31. The front end of the mounting frame 31 is fixedly connected to the top of the rear end of the frame 1. A motor 32 is provided at the rear end of the mounting frame 31. A rotating plate 33 is provided on the output shaft of the motor 32. A connecting rod 34 is rotatably connected to the lower end of the rotating plate 33.

The operation is convenient and improves work efficiency.

[0027] Working Principle: First, shock-absorbing mechanisms 2 are installed on the top sides of the frame 1 to ensure the stability and shock absorption effect of the equipment during operation. A clamping mechanism 3 is installed in the middle of the inner wall of the frame 1 to fix and adjust the various components of the device. Further refining the structure of the shock-absorbing mechanism 2, a support plate 21 is firmly connected to the top sides of the frame 1 on one side to ensure structural stability. A handle 22 is provided on the inner wall of the support plate 21, and a spring 23 is installed on the outer wall of the handle 22. The lower end of the spring 23 is tightly fitted to a baffle 24. Bolts 25 are inserted into the inner wall of the baffle 24 to adjust and fix the position of the spring. A baffle plate 26 is fixedly connected to the middle of the outer wall of the handle 22. The inner wall of the support plate 21 is connected to the outer wall of the handle 22 by plugging. The outer wall of the handle 22 is combined with the inner wall of the spring 23 by sleeve to ensure tight fit between the components. The lower inner wall of the handle 22 has a threaded hole that matches the bolt 25 to facilitate the screwing and fixing of the bolt 25. The lower end of the shock absorption mechanism 2 is firmly connected to the top of both sides of the frame 1 to ensure the stability of the overall structure. The front end of the pressing mechanism 3 is firmly connected to the rear end of the frame 1 to form a complete shock-absorbing hammer head 39 device, thereby effectively improving the working efficiency and durability of the tamping machine.

[0028] Then, the front end of the mounting bracket 31 is securely connected to the top of the rear end of the frame 1. At the rear end of the mounting bracket 31, a motor 32 is installed. A rotating plate 33 is mounted on the output shaft of the motor 32. The lower end of the rotating plate 33 is rotatably connected to a connecting rod 34. The lower end of the connecting rod 34 is hinged to a movable plate 35. The two sides of the movable plate 35 are slidably connected to a guide rod 36. A set of springs 37 is fitted on the outer wall of the guide rod 36. The lower end of the springs 37 is securely connected to a damping plate 38. The lower end of the damping plate 38 is fixedly connected to... A hammerhead 39 is attached. Additionally, shock absorber rods 310 are securely connected to both sides of the lower end of the movable plate 35. A set of springs 311 is fitted onto the outer wall of the shock absorber rods 310. The rear end of the mounting bracket 31 is detachably connected to the front end of the motor 32. The output shaft of the motor 32 is connected to one end of the rotating plate 33 via a transmission connection. The lower end of the shock absorber rod 310 penetrates the shock absorber plate 38, and the upper end of the springs 311 is tightly fitted to both sides of the lower end of the shock absorber plate 38, ensuring the stability and functionality of the entire mechanism. During use, the user can manually rotate the handle 22, causing the handle 22 to move the first baffle 24 and the second baffle 26. Spring 23 deforms under the pressure of baffle 24 and baffle 26. The user can then thread bolt 25 through support plate 21 and handle 22 to secure it, facilitating the installation or removal of the shock-absorbing mechanism 2. When the tamping machine is working, the vibrations cause the hammer head 39 to extend and retract via the damping plate 38, driving springs 37 and 311 to dampen the hammer head 39. Simultaneously, the rotating plate 33 drives the connecting rod 34 to swing, which in turn drives the movable plate 35 to slide via the guide rod 36. At this time, spring 37 deforms under the pressure of the movable plate 35, further damping the hammer head 39. The vibration damping mechanism increases the stability of the tamping machine during operation. When the hammer head 39 needs maintenance or replacement, the user can manually unscrew the bolt 25 from the handle 22, and then turn the handle 22 to cause the baffle 26 to compress the spring 23, thereby removing the damping mechanism 2 from the frame 1. At this time, the user can manually remove the motor 32 from the mounting bracket 31, and then remove the damping plate 38 from the connecting rod 34, so that the hammer head 39 can be maintained or replaced. The operation is convenient and improves work efficiency. The above is the working process of the entire device. All contents not described in detail in this manual are existing technologies known to those skilled in the art.
