Description

Technical Field

[0001] This utility model relates to the field of precise coking time timing technology, specifically a gear interlocking mechanism for precise coking time timing. Background Technology

[0002] A gear interlocking mechanism is a structure that locks through gear linkage. It is a mechanical device that achieves mutual restraint and interlocking functions through the meshing of gears. Its main working principle is to rely on the rotation of gears to control the movement of the locking bolt, thereby realizing the interlocking function. Gear interlocking mechanisms are needed in precise timing of coking time to enable synchronous control and action interlocking.

[0003] Based on existing solutions and actual production and processing applications, the current gear interlocking mechanism for precise coking time timing still has some problems, such as:

[0004] When installing the gear interlocking mechanism, it is bolted to the output end of the gearbox of the coke pusher. Because of the bolt installation, there will be a misalignment between the gear shaft and the output shaft.

[0005] Because there is a deviation between the gear shaft and the output shaft during the installation of the gear interlocking mechanism, the timing locking effect of the gear interlocking mechanism is limited. Therefore, this utility model provides a gear interlocking mechanism for accurate timing of coking time to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a gear interlocking mechanism for accurate coking time timing, in order to solve the problem mentioned in the background art that when installing the gear interlocking mechanism, it is installed on the output end of the gearbox of the coking car by bolts. Because the gear interlocking mechanism is installed by bolts, there will be a misalignment between the gear shaft and the output shaft. Due to the deviation between the gear shaft and the output shaft during the installation of the gear interlocking mechanism, the timing locking effect of the gear interlocking mechanism is limited.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gear interlocking mechanism for precise timing of coking time, including a reduction gearbox with an output shaft located at the rear center;

[0008] Also includes:

[0009] A fixed plate is installed inside the rear side of the gearbox, and a limiting structure is connected to the outer side of the middle part of the fixed plate. The limiting structure includes a spring, a moving rod and a limiting rod, and the limiting rod is installed on the outer side of the middle part of the fixed plate. A spring is provided on the inner side of the middle part of the fixed plate, and a moving rod is connected through the middle part of the spring.

[0010] A connecting block is fixedly installed inside the front side of the output shaft, and a positioning structure is connected to the outside of the connecting block. The positioning structure includes a gear shaft, a fixing rod, and a positioning rod. The positioning rod is installed inside the middle side of the output shaft. The gear shaft is connected to the inside of the positioning rod, and the fixing rod is connected to the right side of the front end of the gear shaft. A housing is movably connected to the outside of the positioning structure.

[0011] Preferably, an installation block is fixedly installed on the outer front end of the housing, and the left front end of the housing is movably connected to the outer side of the gear shaft.

[0012] Preferably, a main gear is movably connected to the left side of the housing, and the front end of the main gear is fixedly connected to the rear end of the gear shaft, and a driven gear is movably installed on the right side of the main gear;

[0013] The upper side of the inside of the box is provided with a connecting groove, and a locking bolt is movably installed inside the connecting groove. A connecting block is fixedly installed on the upper left side of the locking bolt.

[0014] Preferably, the gear and the bolt are meshed, the bolt and the connecting groove are slidably connected, and the vertical cross-section between the bolt and the connecting block forms an "L" shape.

[0015] Preferably, the gear shaft and the connecting block are engaged, and the gear shaft and the fixing rod are threaded.

[0016] Preferably, the fixed plate and the movable rod are telescopically slidingly connected, and the movable rod and the mounting block are engagingly connected.

[0017] Preferably, the fixing plate and the limiting rod are connected by a thread and the fixing plate and the limiting rod limit the mounting block.

[0018] Preferably, the vertical cross-section of the positioning rod is triangular, and the positioning rods are symmetrically distributed about the center line of the gear shaft.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the gear interlocking mechanism for precise coking time timing is provided with a limit structure, which can limit the gear interlocking mechanism, thereby serving as an installation structure for the gear interlocking mechanism, and is also provided with a positioning structure, which can position the gear shaft, thereby ensuring time accuracy;

[0020] 1. By placing the gearbox body on the rear side of the gearbox, the gearbox body drives the mounting block to engage inside the fixed plate, thereby causing the mounting block to push the moving rod to move inward, which in turn causes the moving rod to extend the spring, which in turn causes the moving rod to move outward, thus making the moving rod engage with the inner side of the middle of the mounting block. Rotating the limiting rod causes the limiting rod to be threadedly connected to the outer side of the middle of the fixed plate, thereby causing the limiting rod to move inward, and thus making the limiting rod threadedly connected to the outer side of the middle of the mounting block, which facilitates the installation of the gearbox body;

[0021] 2. The gear shaft is installed inside the output shaft by the housing, which moves the gear shaft forward from the inside of the positioning rod. This positions the gear shaft and engages it on the outer rear end of the connecting block. Rotating the fixing rod causes it to be threaded on the right side of the middle of the output shaft. This moves the fixing rod to the left and then threaded on the right side of the front end of the gear shaft, facilitating the positioning and installation between the gear shaft and the output shaft.

[0022] 3. The output shaft is driven to rotate by the gearbox, which in turn drives the gear shaft to rotate on the left side of the housing. This causes the gear shaft to drive the main gear to rotate on the left side inside the housing, which in turn causes the driven gear, which meshes with the main gear, to rotate. The main gear and the driven gear mesh strictly according to the gear ratio, ensuring that the rotation angle ratio between the drive shaft and the driven shaft is fixed. This controls the action interval time, causing the locking bolt, which meshes with the driven gear, to move to the right inside the connecting groove, so that the locking bolt is locked into the locking position, facilitating gear interlocking.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-7 This utility model provides a technical solution: a gear interlocking mechanism for precise timing of coking time, comprising a reduction gearbox 1, a mounting block 2, a housing 3, a main gear 4, a driven gear 5, an output shaft 6, a connecting block 7, a gear shaft 8, a fixing rod 9, a fixing plate 10, a spring 11, a moving rod 12, a limiting rod 13, a locking bolt 14, a positioning rod 15, a connecting groove 16, and a connecting block 17. In operation, the specific details are as follows... Figure 1 and Figure 3As shown, a fixed plate 10 is fixedly installed on the outer rear end of the gearbox 1. A spring 11 is fixedly installed on the inner side of the middle of the fixed plate 10. A moving rod 12 is connected through the middle of the spring 11. A limiting rod 13 is movably connected on the outer side of the middle of the fixed plate 10. An mounting block 2 is movably installed on the inner side of the fixed plate 10. When the gearbox 3 is manually placed on the rear side of the gearbox 1 and pushed forward, the gearbox 3 causes the mounting block 2 to move forward. As a result, the mounting block 2 moves forward inside the fixed plate 10, and then pushes the moving rod 12 inward on the inner side of the middle of the fixed plate 10. The moving rod 12 causes the spring 11 to extend, thereby causing the mounting block 2 to engage inside the fixed plate 10. This eliminates the pushing force of the mounting block 2 on the moving rod 12, allowing the spring 11 to move the moving rod 12 outward under its elastic action. This causes the moving rod 12 to engage with the inner side of the middle of the mounting block 2. Then, the limiting rod 13 is tightened, causing it to be threaded on the outer side of the middle of the fixed plate 10 under the tightening action. This causes the limiting rod 13 to move inward under the thread action between the limiting rod 13 and the fixed plate 10, thus making it threaded on the outer side of the middle of the mounting block 2. This facilitates the installation of the housing 3.

[0033] Specific examples Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the gearbox 1 has an output shaft 6 located at the rear center, a connecting block 7 fixedly installed at the front of the output shaft 6, a positioning rod 15 fixedly installed at the center of the output shaft 6, a gear shaft 8 movably installed inside the positioning rod 15, and a fixing rod 9 movably installed at the rear right side of the output shaft 6. The gearbox 3 is manually placed at the rear of the gearbox 1, causing the gearbox 3 to move the gear shaft 8 forward inside the output shaft 6. This causes the gear shaft 8 to move forward inside the connecting groove 16, and then the gear shaft 8 to engage with the connecting block 7 at the rear outer side. The fixing rod 9 installed at the middle right side of the output shaft 6 is then tightened, causing the fixing rod 9 to be threadedly connected at the middle right side of the output shaft 6. This threaded action between the output shaft 6 and the fixing rod 9 causes the fixing rod 9 to move to the left, and then the fixing rod 9 is threadedly connected at the front right side of the gear shaft 8, facilitating the fixation of the output shaft 6 and the gear shaft 8.

[0034] Specific examples Figure 1 , Figure 4 , Figure 6 and Figure 7As shown, the main gear 4 is movably connected to the left side inside the housing 3. The front side of the main gear 4 is fixedly connected to the rear side of the gear shaft 8. The driven gear 5 is movably connected to the right side of the main gear 4. A connecting groove 16 is opened on the upper side inside the housing 3. A locking bolt 14 is movably installed on the upper side of the driven gear 5. A connecting block 17 is fixedly installed on the left side of the upper end of the locking bolt 14. The main gear 4 and the driven gear 5 mesh strictly according to the gear ratio to ensure that the rotation angle ratio between the driving shaft and the driven shaft is fixed, thereby controlling the action interval time. The output shaft 6 is driven to rotate through the reduction gearbox 1, so that the output shaft 6 drives the gear 8. The axle 8 rotates, causing the gear shaft 8 to drive the main gear 4 to rotate on the left side inside the housing 3. Under the action of the main gear 4's rotation, the driven gear 5, which meshes with the main gear 4, rotates inside the housing 3. Under the action of the driven gear 5's rotation, the locking bolt 14, which meshes with the driven gear 5, moves to the right inside the connecting groove 16. Under the action of the locking bolt 14's movement, the locking bolt 14 drives the connecting block 17 to move to the right inside the connecting groove 16, thereby causing the locking bolt 14 to engage in the locking position, facilitating gear interlocking.
