Description
Technical Field
[0001] This utility model relates to the field of tamping hammer rod technology, and in particular to a tamping hammer rod motion monitoring device. Background Technology
[0002] The coke oven tamping machine is mainly used to compact coal before coking in a coke oven, forming a high-density coal cake. In the specific operation process, loose coal is first loaded into the coal box of the tamping machine. Then, multiple sets of tamping hammers tamp the coal in layers and multiple times to form a complete coal cake. After that, the bottom plate of the coal box is opened, and the coal cake is pushed into the coal loading car and transported to the coke oven carbonization chamber for subsequent coking processes.
[0003] However, existing tamping hammers lack effective real-time motion monitoring methods during coal tamping operations. This makes it impossible for workers to accurately obtain the real-time movement position information of each set of tamping hammers during the operation, resulting in an inability to accurately track changes in the height of the coal briquettes. Secondly, when a set of tamping hammers malfunctions, workers cannot be notified in a timely manner, thus affecting the quality of the tamping operation. Summary of the Invention
[0004] To solve the above-mentioned technical problems, this utility model provides a tamping hammer rod motion monitoring device. The technical solution of this utility model is as follows:
[0005] A tamping hammer motion monitoring device includes a fixed frame and a scissor frame. The fixed frame is fixedly connected to the lower front side of the tamping machine frame. The scissor frame consists of two arms hinged together in the middle by a shaft. The shaft is detachably fixed to the upper surface of the fixed frame. A C-shaped frame is fixedly connected to the rear end of each arm. A vertical fixed beam is fixedly connected to the rear opening of the C-shaped frame. A movable hole is opened through the middle of the fixed beam. A central shaft is rotatably connected inside the movable hole. A rotating disk is detachably fixed to the rear end of the central shaft. An encoder is detachably fixed to the inner side of the C-shaped frame. The rotating shaft of the encoder is connected to the front end of the central shaft. The front ends of the two arms are connected by an elastic constraint assembly. The two rotating disks abut against the left and right sides of the tamping hammer under the action of the elastic constraint assembly.
[0006] Optionally, a base plate is fixedly connected to the lower end of the shaft, and the base plate is fixed to the upper surface of the fixing frame by bolts.
[0007] Optionally, the left and right sides of the C-shaped frame are symmetrically fixed with fixing buckles by screws, and the encoder is clamped and fixed between the two sets of fixing buckles.
[0008] Optionally, a receiving hole is provided through the center of the rotating disk, and the rear end of the central shaft is inserted into the receiving hole and the two are fixed together by a fixing bolt.
[0009] Optionally, multiple sets of positioning ribs are fixedly provided at equal intervals in an annular shape on the outer side of the central shaft, and multiple sets of positioning grooves that cooperate with the positioning ribs are provided at equal intervals in an annular shape on the inner side wall of the receiving hole.
[0010] Optionally, a polygonal deep hole is formed at the center of the front end face of the central shaft, and a polygonal sleeve is fixedly sleeved on the outside of the encoder shaft, with the polygonal sleeve inserted into the interior of the polygonal deep hole.
[0011] Optionally, a rubber ring is fitted around the outer side of the rotating disk.
[0012] Optionally, the elastic constraint assembly includes two sets of C-frames and a tension spring. The open sides of the two sets of C-frames are rotatably connected to the front ends of the two support arms, respectively. The tension spring is located between the two sets of C-frames, and the two ends of the tension spring are connected to the corresponding C-frames on one side through two sets of fasteners.
[0013] Optionally, a connecting hole is provided through the center of the vertical side of the C-shaped frame. The fixing component includes a threaded post and a pull ring. The threaded post is movably inserted into the inside of the connecting hole. The pull ring is fixedly connected to the end of the threaded post near the tension spring and connected to the end of the tension spring. A locking nut is threaded onto the end of the threaded post away from the tension spring.
[0014] All of the above optional technical solutions can be combined arbitrarily, and this utility model does not provide a detailed description of the structure after each combination.
[0015] The beneficial effects of this utility model through the above solution are as follows:
[0016] In this invention, the two sets of rotating disks, under the action of the elastic constraint components, can always be tightly fitted to the left and right sides of the tamping hammer rod, ensuring that the tamping hammer rod can continuously drive the rotating disks to rotate during the up and down tamping operation. The rotation of the rotating disks is transmitted to the encoder shaft through the central shaft. The encoder monitors the rotation direction, speed, and angle of the shaft in real time, thereby enabling the encoder to indirectly monitor the movement position information of the tamping hammer rod in real time, and thus achieve real-time tracking of changes in coal cake height. Secondly, the operator can promptly determine whether there is a fault in the set of tamping hammer rods based on the motion data monitored by the encoder, and can handle the fault situation in a timely manner.

[0026] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0027] Please see Figure 1-7This utility model provides a tamping hammer rod motion monitoring device, including a fixed frame 2 and a scissor frame 3. The fixed frame 2 is fixedly connected to the lower front side of the tamping machine frame 1 by multiple sets of support frames. The scissor frame 3 consists of two support arms 31 hinged in the middle by a shaft 32. The shaft 32 is detachably fixed to the upper surface of the fixed frame 2. C-shaped frames 4 are fixedly connected to the rear ends of the two support arms 31. A vertical fixed beam 5 is fixedly connected to the rear opening of the C-shaped frame 4. A movable hole 51 is opened through the middle of the fixed beam 5. A central shaft 6 is rotatably connected inside the movable hole 51. A rotating disk 7 is detachably fixed to the rear end of the central shaft 6. An encoder 8 is detachably fixed to the inner side of the C-shaped frame 4. The rotating shaft of the encoder 8 is connected to the front end of the central shaft 6. The front ends of the two support arms 31 are connected by an elastic constraint component 9. The two sets of rotating disks 7 abut against the left and right sides of the tamping hammer rod under the action of the elastic constraint component 9.
[0028] In this invention, the two sets of rotating disks 7, under the action of the elastic constraint component 9, can always be tightly fitted to the left and right sides of the tamping hammer rod, ensuring that the tamping hammer rod can continuously drive the rotating disks 7 to rotate during the up and down tamping operation. The rotation of the rotating disks 7 is transmitted to the rotating shaft of the encoder 8 through the central shaft 6. The encoder 8 monitors the rotation direction, speed, and angle of the rotating shaft in real time, thereby enabling the encoder 8 to indirectly monitor the movement position information of the tamping hammer rod in real time, and thus achieve real-time tracking of changes in coal cake height. Secondly, the operator can promptly determine whether there is a fault in the set of tamping hammers based on the motion data monitored by the encoder 8, and can handle the fault situation in a timely manner.
[0029] Furthermore, during vertical tamping operations, the tamping hammer often sways left and right. By incorporating the elastic constraint component 9, the two rotating disks 7 can always remain tightly fitted to the left and right sides of the tamping hammer, preventing them from separating due to swaying. For example, when the tamping hammer sways to the left, the left rotating disk 7 will shift to the left. Under the action of the elastic constraint component 9, the right rotating disk 7 will promptly move to the left, ensuring that both rotating disks 7 remain in contact with the tamping hammer. This allows the encoder 8 to accurately record the movement position information of the tamping hammer.
[0030] It should be noted that in practical applications, the rotation parameters of the two sets of rotating disks 7 recorded by the two sets of encoders 8 on the left and right sides of a single set of tamping hammer rods should remain consistent or fluctuate within a small range. When the parameters recorded by the two sets of encoders 8 are inconsistent or fluctuate significantly, it indicates that one set of rotating disks 7 may be slipping with the tamping hammer rod or there may be other malfunctions, and staff can promptly check and maintain it. Furthermore, the rotation parameters recorded by the encoders 8 of this set of tamping hammer rods can be compared with the rotation parameters recorded by the encoders 8 of other tamping hammer rods to determine if a malfunction exists.
[0031] Furthermore, a base plate 33 is fixedly connected to the lower end of the shaft 32, and the base plate 33 is fixed to the upper surface of the fixing frame 2 by bolts.
[0032] Furthermore, the left and right sides of the C-shaped frame 4 are symmetrically fixed with fixing buckles 41 by screws, and the encoder 8 is clamped and fixed between the two sets of fixing buckles 41.
[0033] Specifically, the encoder 8 is secured by two sets of retaining clips 41, facilitating subsequent maintenance and disassembly. Secondly, in practical applications, protective covers can be added to both sides of the C-frame 4 to effectively protect the encoder 8.
[0034] Furthermore, a receiving hole 71 is provided through the center of the rotating disk 7, and the rear end of the central shaft 6 is inserted into the interior of the receiving hole 71 and the two are fixed together by a fixing bolt 74.
[0035] Specifically, fixing holes 62 are provided on both the left and right sides of the central shaft 6, and side holes 73 are provided on both sides of the central disk of the rotating disk 7. When installing the rotating disk 7, simply place the rotating disk 7 on the outside of the central shaft 6, and then screw the fixing bolts 74 into the side holes 73 so that their ends abut against the fixing holes 62. The rotating disk 7 adopts a detachable structure for easy subsequent maintenance and replacement.
[0036] Furthermore, multiple sets of positioning ribs 61 are fixedly arranged in an annular pattern on the outer side of the central shaft 6, and multiple sets of positioning grooves 72 that cooperate with the positioning ribs 61 are opened in an annular pattern on the inner side wall of the receiving hole 71.
[0037] Specifically, when installing the rotating disk 7, it is necessary to fit the rotating disk 7 onto the outside of the central shaft 6. During fitting, the multiple sets of positioning grooves 72 in the receiving hole 71 can be aligned with the positioning ribs 61 on the outside of the central shaft 6 and inserted, thereby indirectly aligning the fixing hole 62 with the receiving hole 71 quickly.
[0038] Furthermore, a polygonal deep hole 63 is provided at the center of the front end face of the central shaft 6, and a polygonal sleeve 81 is fixedly sleeved on the outside of the rotating shaft of the encoder 8, and the polygonal sleeve 81 is inserted into the interior of the polygonal deep hole 63.
[0039] Specifically, when installing the encoder 8, first insert the polygonal sleeve 81 on the outside of the encoder 8 shaft into the polygonal deep hole 63. After it is inserted into place, the encoder 8 is fixed and locked by the fixing buckle 41.
[0040] Furthermore, a rubber ring 75 is fitted on the outer side of the rotating disk 7.
[0041] Specifically, by sleeved with a rubber ring 75 on the outside of the rotating disk 7, the friction between the rotating disk 7 and the tamping hammer rod can be increased, thereby ensuring that the tamping hammer rod can effectively drive the rotating disk 7 to rotate when moving up and down, avoiding uneven rotation or slippage caused by insufficient friction. The rubber ring 75 has good wear resistance and can resist friction and wear during long-term use.
[0042] Furthermore, the elastic constraint assembly 9 includes two sets of C-shaped frames 91 and a tension spring 93. The open sides of the two sets of C-shaped frames 91 are rotatably connected to the front ends of the two support arms 31 respectively. The tension spring 93 is located between the two sets of C-shaped frames 91, and the two ends of the tension spring 93 are connected to the corresponding C-shaped frame 91 through two sets of fixing members 92 respectively.
[0043] Specifically, under the action of the tension spring 93, the front ends of the two support arms 31 can be controlled within an effective range, thereby indirectly controlling the two sets of rotating disks 7 at the rear ends of the two support arms 31 to maintain an appropriate distance.
[0044] Furthermore, a connecting hole 911 is provided through the center of the vertical side of the C-shaped frame 91. The fastener 92 includes a threaded post 921 and a pull ring 922. The threaded post 921 is movably inserted into the interior of the connecting hole 911. The pull ring 922 is fixedly connected to the end of the threaded post 921 near the tension spring 93 and connected to the end of the tension spring 93. A locking nut 923 is threaded onto the end of the threaded post 921 away from the tension spring 93.
[0045] Specifically, by setting the fixing component 92, the elastic preload of the elastic constraint component 9 can be adjusted. Rotating the locking nut 923 causes the threaded post 921 to gradually penetrate into the C-frame 91, thereby applying tension to the tension spring 93. Adjusting the elastic preload of the elastic constraint component 9 indirectly adjusts the contact between the two sets of rotating discs 7 at the other end of the scissor frame 3 and the tamping hammer rod, ensuring they always maintain a suitable contact state. Secondly, the fixing component 92 facilitates the quick installation and removal of the tension spring 93. When the tension spring 93 needs to be removed, simply unscrew the locking nut 923 to separate the threaded post 921 from the connecting hole 911, allowing for rapid disassembly of the tension spring 93. When the tension spring 93 needs to be installed, simply insert the threaded post 921 into the connecting hole 911 and then tighten the locking nut 923.
[0046] The above are merely preferred embodiments of this utility model and are not intended to limit 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 technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
