Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of coke pusher car components, and in particular to a sliding door mechanism for a self-pressurized horizontal iron coke pusher car. Background Technology
[0002] The coke pusher is one of the key pieces of equipment in the coking process. It mainly runs along the front side of the coke oven carbonization chamber to push the carbonized coke out of the carbonization chamber. At the same time, it works with the furnace door opening and closing mechanism to complete the processes of coal charging, coke pushing and cleaning. The coke pusher sliding door mechanism is responsible for opening and closing the furnace door. Its performance stability and sealing are directly related to the coke oven's operating efficiency and production safety.
[0003] In existing coke pusher car sliding door mechanisms, the sides of the door mostly employ vertically arranged limiting components or clamping mechanisms, using pins or slide rails to guide and fix the door. Under long-term high-temperature and frequent opening and closing conditions, this type of structure relies mainly on local point-contact fixing in its traditional vertical limiting method, lacking effective support at the bottom of the door. This makes the door prone to slight swaying or displacement during operation. Furthermore, the lack of bottom lateral support and clamping design means that when the coke pusher car is subjected to impact vibration or its running trajectory is unstable, there is a risk of uneven force on the sliding door, leading to jamming or even detachment, thus affecting equipment safety. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing coke pusher car sliding door mechanism is prone to door shaking and may cause jamming or even falling off under impact and vibration due to the single force of the side vertical limiting structure and the lack of lateral support and clamping design at the bottom.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a horizontal iron self-pressurized coke pusher sliding door mechanism, including a door frame, a door panel rotatably connected to the inner side of the door frame through multiple door hinges, the door frame being detachably mounted on one side of the car body, and cavities being opened on both sides of the bottom of the door frame, a compression spring being fixedly installed at the bottom of the cavity, a connecting block being fixedly connected to the top of the compression spring, one side of the connecting block being fixedly connected to the bottom of one set of door hinges, a rectangular groove being fixedly connected to one side of the connecting block through a connecting arm, a rib being tightly inserted between the two rectangular grooves, and the top of the rib being tightly connected to the door panel.
[0006] As a further improvement of this utility model, the connecting block is set as a T-shaped cast iron block, and the stiffness of the compression spring is set to 30 ~ 60 N / mm.
[0007] As a further improvement of this utility model, the door hinge includes two rotating shaft seats and one movable shaft seat, and both the rotating shaft seats and the movable shaft seat are fastened to the inner wall of the door frame.
[0008] As a further improvement of this utility model, the movable bearing includes a bearing and a friction sleeve fixed to one side of the connecting block. The inner and outer surfaces of the friction sleeve are both made of frosted material. The bottom end of the bearing has a bottom groove for the friction sleeve to be inserted into. The top end of the bearing has an insert shaft, which passes through the bearing and the friction sleeve.
[0009] As a further improvement of this utility model, connecting plates are fixedly provided at the four corners of the door frame, and mounting screw holes are opened in the center of the connecting plates, and mounting bolts are passed through the mounting screw holes.
[0010] As a further improvement of this utility model, a connecting platform is fixedly provided on one side of the door panel, the rib is abutted and provided below the connecting platform, and the top of the connecting platform is reinforced and connected to the connecting platform by bolts.
[0011] The beneficial effects of this utility model are as follows: A compression spring, connecting block, and rectangular groove are installed at the bottom of the door frame, and ribs are fastened between the rectangular grooves. This creates a reliable lateral contact and pressing structure between the ribs and the connecting platform, effectively overcoming the problem of single-force distribution caused by traditional sliding door mechanisms relying solely on lateral vertical limiting and lacking support at the bottom of the door. This design not only forms a stable lateral pressing force when the door panel is closed, preventing door swaying and displacement and improving the sealing performance of the furnace door, but also allows the ribs to evenly distribute the force when the coke pusher is subjected to impact or vibration, preventing the door panel from jamming or falling off due to uneven force distribution. Simultaneously, the movable shaft seat, through the damping cooperation of the friction sleeve and the insert shaft, further enhances the operational stability of the door panel, enabling the sliding door to maintain reliable positioning even under high temperature and strong vibration conditions. Therefore, this structure effectively solves the defects of unstable fixing and insufficient lateral support in existing sliding door mechanisms, significantly improving the safety and service life of the coke pusher sliding door mechanism.

It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.
[0016] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0017] This utility model provides a horizontal iron self-pressurized coke pusher car sliding door mechanism, including a door frame 1; As attached Figure 1 As shown, the door frame 1 is rotatably connected to the door panel 2 via multiple door hinges. The door frame 1 is detachably mounted on one side of the vehicle body. Connecting plates 8 are fixedly mounted at the four corners of the door frame 1. The connecting plates 8 have mounting screw holes in their centers, and mounting bolts pass through the mounting screw holes. The connecting plates 8 and mounting bolts are used to provide the installation effect for the door frame 1.
[0018] As attached Figure 1 , 2 As shown in Figure 4, chambers are provided on both sides of the bottom of the door frame 1. A compression spring 3 is fixedly installed at the bottom of the chamber. A connecting block 4 is fixedly connected to the top of the compression spring 3. The connecting block 4 is a T-shaped cast iron block, and the stiffness of the compression spring is set to 30 ~ 60 N / mm. One side of the connecting block 4 is fixedly connected to the bottom of one set of door hinges. A rectangular groove 5 is fixedly connected to one side of the connecting block 4 through a connecting arm. A rib 6 is fastened between the two rectangular grooves 5. The top of the rib 6 is fastened to the door panel 2. A connecting platform 9 is fixedly installed on one side of the door panel 2. The rib 6 abuts against the bottom of the connecting platform 9. The top of the connecting platform 9 is reinforcedly connected to the connecting platform 9 by bolts, providing fastening assembly for the rib 6.
[0019] As attached Figure 3As shown, the door hinge includes two pivot seats and one movable pivot seat 7, and both the pivot seats and the movable pivot seat 7 are securely assembled to the inner wall of the door frame 1. The movable pivot seat 7 includes a pivot seat 71 and a friction sleeve 72 fixed to one side of the connecting block. The inner and outer surfaces of the friction sleeve 72 are made of frosted material. The bottom end of the pivot seat 71 has a bottom groove for the friction sleeve to be inserted into, and the top end of the pivot seat 71 is provided with a shaft 73, which passes through the pivot seat 71, the friction sleeve 72, and the movable pivot seat 7. Under normal conditions, since the outer wall of the shaft 73 and the friction sleeve 72 are inserted into each other, the friction force and damping performance are improved. At the same time, since the friction sleeve 72 is fixed to one side of the door panel 2, it does not affect the normal opening and closing of the door panel 2.
[0020] Working Principle: In practical application, a compression spring 3 is installed in the cavity at the bottom of the door frame 1. A connecting block 4 is fixed to the upper end of the compression spring 3. When it is necessary to release the lateral restriction of the door panel 2, the bolts between the rib 6 and the connecting platform 9 are first unscrewed. The operator then presses down on the connecting block 4, causing the compression spring 3 to compress and deform within the cavity. The connecting block 4 then moves the rectangular groove 5, which is fixed to it, downwards, causing the rib 6, originally fastened between the rectangular grooves 5, to disengage from the connecting platform 9 on one side of the door panel 2, thereby releasing the restriction and reinforcement effect on the door panel 2. Simultaneously, the frictional action of the friction sleeve 72 and the insert shaft 73 provides damping and stable support for the opening and closing of the door panel 2, preventing the door panel 2 from wobbling or swinging rapidly due to inertia during operation. The entire process achieves the release of the restriction structure through the downward movement of the compression spring 3, combined with the frictional damping of the movable shaft seat 7, allowing the door panel 2 to open and close smoothly under structurally stable conditions.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
