[0031] The coal loading car is one of the main mechanical equipment used on the side-loaded ramming coke oven in the coking plant. It runs on the side of the coke oven machine. Its main function is to cooperate with the tamping machine, feeder and smoke guide car to load the coal cakes into the carbonization chamber of the coke oven. The coal loading car mainly consists of a traveling device, a front baffle device, a rear baffle device, a coal box device, a first locking mechanism, a coal loading device, a coal cake flattening mechanism, a residual coal recovery device, a dust removal device, etc.

[0032] The main function of the coal loading car is to cooperate with the tamping machine, feeder and smoke guide car to load the coal cakes into the carbonization chamber of the coke oven. At present, the original design of the coal loading car is that during the coal loading process, the coal supporting bottom plate and the rear baffle plate will send the coal cakes into the carbonization chamber. A 60x60mm slot hole is opened near the front baffle plate on the movable wall of the coal box device. The locking hook hook head extends from the slot hole to lock the rear baffle plate. The locking device is used to lock the rear baffle plate of the coal loading car during the withdrawal of the coal supporting bottom plate, leaving the coal cakes in the carbonization chamber. This design solves the problem that the rear baffle device can be locked to send the coal cakes into the carbonization chamber. However, during the actual operation of the equipment, there is a large amount of coal leakage or blockage in the locking hook slot hole. Coal powder falls from the slot hole to the coke oven platform and the machine side track foundation. A large amount of coal powder accumulates on the equipment frame. When the wind blows, the powdered coal is scattered everywhere, causing serious dust on the coke oven machine side, and corroding the equipment frame, polluting equipment such as reducers, and causing a very large workload and environmental pollution to the personnel on the job.

[0033] In order to solve the above-mentioned problems, the present application proposes a locking device for a coke oven coal loading car. The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0034] Reference Figures 1 to 5The embodiment of the present application provides a locking device for a coke oven coal loading car, comprising a coal loading car furnace door sealing frame 110, a front baffle, a rear baffle 113, a coal loading car 112, a coal supporting bottom plate 116, a first movable wall plate 114, a second movable wall plate 115, a first locking mechanism and a sprocket transmission mechanism; the front baffle, the rear baffle 113, the first movable wall plate 114, the second movable wall plate 115 and the coal supporting bottom plate 116 are enclosed to form a coal box, the coal box is placed in the coal loading car 112, the sprocket transmission mechanism is arranged at the bottom of the coal loading car 112, and the sprocket transmission mechanism is connected to the side wall of the coal loading car 112, the coal supporting bottom plate 116 and the rear baffle 113 are both arranged on the sprocket transmission mechanism, the coal loading car furnace door sealing frame 110 is connected to the side of the front baffle away from the coal box; the first locking mechanism The structure includes two first locking hooks 120, two first locking hook bases 121, two first locking hook cylinders 122 and a locking rack 124. The first locking hooks 120 correspond to the first locking hook bases 121 and the first locking hook cylinders 122 respectively. The two first locking hook bases 121 are symmetrically welded to both sides of the sealing frame 110 of the furnace door of the coal charging car, and the first locking hook bases 121 are arranged close to the front baffle. The first locking hooks 120 are movably arranged on the corresponding first locking hook bases 121. The first locking hook cylinders 122 are connected to the corresponding first locking hooks 120. The rear baffle 113 is fixed on the locking rack 124. The hook head of the first locking hook 120 can hook the locking rack 124 when the rear baffle 113 moves to the position of the first locking hook 120.

[0035] It should be noted that the front baffle, the rear baffle 113, the first movable wall plate 114, the second movable wall plate 115 and the coal supporting bottom plate 116 together form a coal box, wherein the coal supporting bottom plate 116 is arranged on the bottom plate of the coal box, the first movable wall plate 114 and the second movable wall plate 115 are arranged on both sides of the coal box, and the front baffle and the rear baffle 113 are respectively arranged on the front and rear sides of the coal box.

[0036] It should be noted that in the production process of loading coal into the ramming coke oven, the rammed coal cakes need to be sent from the coal loading car into the carbonization chamber using a coal supporting plate. The coal supporting bottom plate 116 is driven by a sprocket transmission mechanism. When the coal is delivered, the coal supporting bottom plate 116 and the coal cakes thereon and a part of the rear baffle 113 are sent into the coke oven together. When the sprocket transmission mechanism pulls the coal supporting plate backwards, the rear baffle 113 will be temporarily fixed in front of the furnace through the locking hook rack and the cooperation with the two first locking hooks 120, and the coal cakes are blocked in the furnace.

[0037] It should be noted that, refer to Figure 8 , the locking structure 200 of the tailgate 113 in the prior art is arranged close to one side of the tailgate 113; Figure 7, the locking rack 124 of the rear baffle 113 is modified and shifted to achieve the function of locking the rear baffle 113 outside the coal box, that is, the locking rack 124 of the rear baffle 113 of the coal loading car is changed from the original rear locking to the middle locking, and a 250 channel steel welding frame is used for the rear baffle 113 of the coal loading car, and 12 bolts are used to fix the locking rack 124. Among them, 250 channel steel means that the width of the channel steel is 250 mm. In this application, the first locking hook 120 is moved from the front baffle in the related technology to the coal loading car furnace door sealing frame 110 in front of the front baffle, and the locking mechanism located at the rear position of the rear baffle 113 is correspondingly moved to the middle position of the rear baffle 113. If only the position of the first locking hook 120 is moved without changing the position of the locking rack 124, it will cause the first locking hook 120 to be unable to hook the locking rack 124, and thus the rear baffle 113 cannot be locked.

[0038] It should be noted that Figure 1 A in FIG. 1 represents the installation position of the first locking mechanism on the sealing frame 110 of the furnace door of the coal charging car.

[0039] Specifically, after the coal cakes are loaded into the coal box, the sprocket transmission mechanism drives the coal supporting bottom plate 116 and the rear baffle 113 to send the coal cakes into the carbonization chamber. At this time, the coal supporting bottom plate 116 needs to be pulled out, and the rear baffle 113 needs to be locked to prevent the coal cakes from being pulled out of the carbonization chamber. After the coal supporting bottom plate 116 is pulled out of the carbonization chamber by the sprocket transmission mechanism, the lock of the rear baffle 113 by the first locking mechanism is released, and the rear baffle 113 is pulled out of the carbonization chamber by the limiting wire rope; wherein, the first locking mechanism locks the rear baffle 113 The locking of the plate 113 is achieved by the first locking hook cylinder 122 driving the hook head on the corresponding first locking hook 120 to hook the locking rack 124, and the two symmetrical first locking hooks 120 respectively hook the two ends of the locking rack 124 to fix and limit the locking rack 124, thereby achieving the locking of the rear baffle 113; after the coal supporting bottom plate 116 is pulled out, the corresponding locking hook is pushed by the first locking hook cylinder 122 to release the locking of the locking rack 124 by the first locking hook 120.

[0040] In the present application, the two first locking hooks 120 are fixed to the front section of the front baffle of the coal loader, that is, the coal loader furnace door sealing frame 110, and a locking hook frame, that is, two first locking hook bases 121 are made on the coal loader furnace door sealing frame 110, which are connected to the two first locking hook cylinders 122 by utilizing the idle hydraulic oil circuit system of the coal loader furnace door sealing device, and the locking rack 124 on the rear baffle 113 is modified and shifted to achieve the function of locking the rear baffle 113 outside the coal box. The frame of the coal loader furnace door sealing device is used as a carrier, and two symmetrical first locking hook bases 121 are welded inside the frame, eliminating the equipment problem of a large amount of coal powder spilling from the locking hole 126 of the original embedded first locking mechanism, and the modification is to seal the slot of the coal box of the coal loader into an integral coal loading mechanism, and the first locking mechanism is locked independently. Through this arrangement, the present application changes the first locking mechanism from a coal box embedded type to an external type. The coal loading car serves as an integral coal loading mechanism, and the first locking mechanism is independently locked, which can effectively reduce the scattering of coal powder from the coal loading car and reduce the labor intensity of manual cleaning of coal powder, while improving the on-site operating environment and reducing the environmental dust concentration.

[0042] It should be noted that when delivering coal, the coal supporting bottom plate 116 and the coal cakes thereon and a part of the rear baffle 113 are sent into the coke oven together. When the closed-loop chain pulls the coal supporting bottom plate 116 backward, the rear baffle 113 will be temporarily fixed in front of the oven, and the coal cakes will be blocked in the oven. The closed-loop chain is driven by the driving mechanism through the reducer and the first sprocket 131 or the second sprocket 132 of the intermediate transmission system to drive the sprocket shaft 130, and then drives the closed-loop chain.

[0043] It should be noted that the driving mechanism is a motor, and the sprocket transmission mechanism also includes a reducer. The motor is connected to one of the multiple first sprockets 131 and the multiple second sprockets 132 through the reducer. The driving mechanism drives the first sprocket 131 or the first sprocket 131 to move through the reducer. The first sprocket 131 or the second sprocket 132 drives the corresponding sprocket and the sprocket shaft 130 to rotate, thereby driving the closed-loop chain to move, and then drives the remaining first sprockets 131 and second sprockets 132 to transmit through the closed-loop chain.
