Description

Technical Field

[0001] This utility model belongs to the field of tamping hammer technology, and specifically relates to a vertical coke oven tamping hammer. Background Technology

[0002] A tamping hammer consists of a hammer rod and a hammer head. The hammer head is located at one end of the hammer rod. A drive mechanism drives the hammer rod to move the tamping hammer along the guide direction of the guide roller, causing the hammer head to act on the coke and compact it. During operation, the tamping hammer will continuously rub against each other, causing the friction plates of the tamping hammer to wear. Therefore, the friction plates need to be replaced and maintained.

[0003] While existing vertical coke oven tamping hammers allow users to easily disassemble and replace the friction plates on the hammer rod, it typically requires time-consuming and laborious installation and disassembly of multiple connecting structures to achieve flexible fixation of the friction plates to the hammer rod. This results in users being unable to quickly and efficiently disassemble and replace the friction plates, causing significant inconvenience and affecting the efficiency of coke processing. Therefore, it cannot fully meet user needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a vertical coke oven tamping hammer, which not only meets the basic requirements for tamping coke, but also allows users to quickly and easily disassemble and replace the friction plates, thereby more fully meeting people's usage needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a vertical coke oven tamping hammer, including an H-shaped steel hammer rod, a hammer head provided at the lower end of the H-shaped steel hammer rod, friction plates snapped onto the front and rear ends of the middle part of the H-shaped steel hammer rod, mounting blocks provided at the front and rear ends of the middle part of the H-shaped steel hammer rod, mounting grooves provided on the friction plates for engaging with the mounting blocks, and a fixing frame slidably provided on both sides of the friction plates in the middle part of the H-shaped steel hammer rod along the left and right direction, and a fixing plate provided on the fixing frame for inserting and fixing the connection between the mounting groove and the mounting block.

[0006] As a further improvement of this utility model, the mounting slot is provided with a through hole for engaging with the fixed insert plate, and the mounting block is provided with a fixing hole for engaging with the fixed insert plate.

[0007] As a further improvement of this utility model, the upper and lower ends of the middle part of the H-shaped steel hammer rod are provided with clearance grooves that are adapted to the fixed frame. The fixed frame is provided with fixing bolts for screwing the H-shaped steel hammer rod, and the H-shaped steel hammer rod is provided with threaded fixing holes for screwing the fixing bolts.

[0008] As a further improvement of this utility model, the number of fixing plates on a fixed frame is four, and the four fixing plates are set corresponding to the upper and lower ends of the mounting block.

[0009] As a further improvement of this utility model, an elastic reset component is also provided between the H-shaped steel hammer rod and the fixed frame.

[0010] As a further improvement of this utility model, the elastic reset component includes a mounting groove provided at the middle side end of the H-shaped steel hammer rod, a fixing groove provided at the side end of the fixing frame that is always fitted and connected with the mounting groove, and a plurality of connecting springs provided between the side end of the H-shaped steel hammer rod and the side end of the fixing frame, the plurality of connecting springs also being located between the mounting groove and the fixing groove.

[0011] As a further improvement of this utility model, a sealing ring that matches the mounting groove is also provided on the inner side wall of the fixing groove.

[0012] As a further improvement of this utility model, an auxiliary moving handle is also provided on the fixed frame. The auxiliary moving handle on the fixed frame makes it easy for the operator to grip it by hand or use tools to push the fixed frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, by setting mounting blocks on the H-shaped steel hammer rod, and corresponding mounting slots for the friction plates, quick locking and positioning between the friction plates and the hammer rod is achieved. Combined with a fixed frame slidably positioned in the middle of the hammer rod and its fixed insert plate, after the friction plates are installed, pushing the fixed frame simultaneously inserts the fixed insert plate into both the through hole of the mounting slot and the fixed locking hole of the mounting block, achieving multi-point synchronous locking. Disassembly simply requires sliding the fixed frame out to release the lock, eliminating the need to disassemble multiple fasteners one by one, greatly simplifying the operation process, significantly improving the friction plate replacement speed, reducing equipment downtime, and enhancing production continuity.

[0014] Secondly, the fixed frame slides with the H-shaped steel hammer rod through a recessed groove, and is further limited by fixing bolts, enhancing the stability of the fixed frame during operation and preventing the fixing plates from loosening due to vibration. Simultaneously, the four fixing plates are symmetrically distributed on the upper and lower sides of the mounting block, forming a multi-point uniform force-bearing structure, effectively dispersing impact loads, improving the fatigue resistance of the connection parts and the overall structural strength, and ensuring the safe and stable operation of the equipment in high-frequency, high-intensity working environments.

[0015] Third, an elastic reset component (such as a connecting spring) is installed between the H-shaped steel hammer rod and the fixed frame. When it is necessary to disassemble the friction plate, only external force needs to be applied to slide the fixed frame to complete the unlocking. After release, the spring automatically rebounds and pushes the fixed frame back to the initial position, avoiding repeated manual adjustments and realizing "one-click pop-out" disassembly preparation, further improving the convenience of operation and the degree of automation.

[0016] Fourth, the sealing ring not only improves the sealing performance between the mounting groove and the fixing groove, but also prevents dust from entering and affecting the spring performance. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 2As shown, a vertical coke oven tamping hammer includes an H-shaped steel hammer rod 101, a hammer head 102 at the lower end of the H-shaped steel hammer rod 101, friction plates 103 snapped onto the front and rear ends of the middle section of the H-shaped steel hammer rod 101, mounting blocks 104 at the front and rear ends of the middle section of the H-shaped steel hammer rod 101, mounting grooves 105 on the friction plates 103 that engage with the mounting blocks 104, and fixed frames 106 slidably mounted on both sides of the friction plates 103 in the middle section of the H-shaped steel hammer rod 101 along the left-right direction. Fixed plates 107 are provided on the fixed frames 106 for inserting and fixing the connection between the mounting grooves 105 and the mounting blocks 104. The fixed frames 106 slide with the H-shaped steel hammer rod 101 through a clearance groove 201, and are further limited by fixing bolts 202, enhancing the stability of the fixed frames 106 during operation and preventing the fixed plates 107 from loosening due to vibration. Meanwhile, four fixed insert plates 107 are symmetrically distributed on the upper and lower sides of the mounting block 104, forming a multi-point uniform force structure, effectively dispersing impact loads, improving the fatigue resistance of the connection parts and the overall structural strength, and ensuring the safe and stable operation of the equipment in high-frequency and high-intensity operating environments.

[0022] like Figure 3 , 5 As shown, the mounting slot 105 is provided with a through hole 108 for engaging with the fixing plate 107, and the mounting block 104 is provided with a fixing hole 109 for engaging with the fixing plate 107.

[0023] like Figure 1 , 3 As shown, the upper and lower ends of the middle part of the H-shaped steel hammer rod 101 are provided with relief grooves 201 that are adapted to the fixed frame 106. The fixed frame 106 is provided with fixing bolts 202 for screwing the H-shaped steel hammer rod 101. The H-shaped steel hammer rod 101 is provided with threaded fixing holes 203 for screwing the fixing bolts 202.

[0024] like Figure 3 , 4 As shown, there are four fixing plates 107 on a fixed frame 106, and the four fixing plates 107 are set at the upper and lower ends of the mounting block 104.

[0025] like Figure 2 , 4As shown, an elastic reset component is also provided between the H-shaped steel hammer rod 101 and the fixed frame 106. The elastic reset component includes a mounting groove 301 located at the middle side end of the H-shaped steel hammer rod 101, and a fixing groove 302 located at the side end of the fixed frame 106 that is always fitted and connected to the mounting groove 301. Multiple connecting springs 303 are provided between the side end of the H-shaped steel hammer rod 101 and the side end of the fixed frame 106, and these connecting springs 303 are also located between the mounting groove 301 and the fixing groove 302. By providing an elastic reset component (such as connecting springs 303) between the H-shaped steel hammer rod 101 and the fixed frame 106, when it is necessary to disassemble the friction plate 103, only external force needs to be applied to slide the fixed frame 106 to unlock it. After release, the springs automatically rebound, pushing the fixed frame 106 back to its initial position, avoiding repeated manual adjustments and achieving "one-click pop-out" disassembly preparation, further improving operational convenience and automation.

[0026] The worker can engage the mounting slot 105 with the mounting block 104 to initially engage and fix the friction plate 103 with the side end of the H-shaped steel hammer rod 101. Then, the worker can push the fixing frame 106 to slide on the H-shaped steel hammer rod 101, so that the fixing plate 107 passes through the through hole 108 and engages with the fixing hole 109 to fix the connection between the mounting slot 105 and the mounting block 104. Then, the worker can make the fixing bolt 202 pass through the side wall of the fixing frame 106 and screw it into the threaded fixing hole 203 to fix it, thereby quickly and stably fixing one end of the connection between the friction plate 103 and the H-shaped steel hammer rod 101. Then, the worker can fix the other end of the connection between the friction plate 103 and the H-shaped steel hammer rod 101 in the same way.

[0027] During the above process, the connecting spring 303 is stretched and stores energy. Then the H-shaped steel hammer rod 101 can be used. During the tamping operation, the H-shaped steel hammer rod 101 drives the hammer head 102 to move up and down reciprocally. The friction plate 103 contacts the external guide rail or guide roller, relying on the high friction coefficient material to provide stable guidance and withstand periodic impact loads.

[0028] When the friction plate 103 needs to be replaced after a period of time, simply separate the fixing bolt 202 from the threaded fixing hole 203 and release the fixing at the connection between the fixing frame 106 and the H-shaped steel hammer rod 101. The stretched connecting spring 303 will rebound, assisting in pushing the fixing frame 106 to slide on the H-shaped steel hammer rod 101, thereby driving the fixing frames 106 and fixing grooves 302 on both sides to move away from each other until the fixing insert plate 107 separates from the fixing clip hole 109 and the through hole 108, releasing the fixing at the connection between the mounting clip groove 105 and the mounting clip block 104, thereby quickly releasing the fixing at the connection between the friction plate 103 and the H-shaped steel hammer rod 101. After that, the friction plate 103 can be removed from the H-shaped steel hammer rod 101 for replacement.

[0029] Because the fixed insert plate 107 can be simultaneously inserted into the through hole 108 of the mounting slot 105 and the fixed locking hole 109 of the mounting block 104 by pushing the fixed frame 106, multi-point synchronous locking can be achieved. During disassembly, the fixed frame 106 only needs to be slid out to release the locked state, eliminating the need to disassemble multiple fasteners one by one. This greatly simplifies the operation process, significantly improves the replacement speed of the friction plate 103, reduces equipment downtime, and enhances production continuity.

[0030] According to another embodiment of the present invention, such as Figure 4 As shown, a sealing ring 304 that matches the mounting groove 301 is also provided on the inner wall of the fixing groove 302. Because the fixing groove 302 and the mounting groove 301 are always fitted together, and the sealing ring 304 improves the sealing performance between the mounting groove 301 and the fixing groove 302, it can effectively prevent dust from entering and affecting the spring performance, thus better meeting people's usage needs.

[0031] According to another embodiment of the present invention, such as Figure 2 , 4 As shown, an auxiliary moving handle 204 is also provided on the fixed frame 106. The auxiliary moving handle 204 is U-shaped and is welded and fixed to the fixed frame 106. The auxiliary moving handle 204 provided on the fixed frame 106 makes it easy for the operator to grip it by hand or push the fixed frame 106 with the help of tools.

[0032] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
