Abstract
Description
Technical Field
[0001] The utility model relates to a smoke control lifting platform device for a coke pushing car furnace door of a ramming coke oven, belonging to the field of coke oven smoke control. Background Art
[0002] At present, in the daily operation of domestic ramming coke ovens, after the coal loading car pushes the coal cakes into the combustion chamber and the coke pushing car closes the furnace door, there is still a problem of unorganized smoke to varying degrees due to the loose sealing of the furnace door blade edge. In this case, the furnace door smoke treatment worker is needed to treat the smoking furnace door blade edge.
[0003] Currently used coke pushers lack fume control platforms, instead featuring first, second, and third-level walking platforms on the pusher body. To control fume from elevated locations, furnace door fume control workers must ascend the inclined ladders between the middle levels of the pusher to the corresponding level, then sidestep outside the pusher to control the fume. Sometimes, fume is emitted between two levels, and workers standing on the lower level cannot reach the fume, so they must climb the upper level guardrails to control the smoke. However, with the increasing intensity of national environmental protection requirements and the strict enforcement of the Environmental Protection Law, the need for this type of fugitive emission control is growing, becoming a bottleneck for the development of coking enterprises. Furnace door fume control is particularly crucial in coke oven production, becoming a crucial step in the entire process.

[0042] See Figure 1 This is an embodiment of the utility model of a ramming coke oven coke pushing car furnace door smoke control lifting platform device,
[0043] It includes a support frame 1, on which a smoke control platform 2 and a lifting mechanism 3 for controlling the lifting of the smoke control platform 2 are installed;
[0044] The support frame 1 is composed of two vertically arranged support columns 9 and two support channel steels 10. The two support columns 9 and the two support channel steels 10 are on the same side. Four wheels are provided on the smoke control platform 2. The wheel width is smaller than the groove width of the support channel steel 10, and the wheels are arranged in the groove of the support channel steel 10.
[0045] Therefore, the smoke control platform 2 uses the groove of the supporting channel steel 10 as a track and is vertically lifted and lowered along the vertical supporting channel steel 10.
[0046] The lifting mechanism 3 of the device controls the lifting of the smoke control platform 2. The specific structure includes a driving device 4, a driving sprocket assembly 5, a first driven sprocket assembly 6, and a second driven sprocket assembly 7. The first driven sprocket assembly 6 and the second driven sprocket assembly 7 are connected to the smoke control platform 2 by ropes.
[0047] The driving sprocket assembly 5 includes a driving shaft 51 and a first sprocket 52 arranged on the driving shaft 51;
[0048] The first driven sprocket assembly 6 includes a first driven shaft 61 and a second sprocket 62 and a third sprocket 63 provided on the first driven shaft 61;
[0049] The second driven sprocket assembly 7 includes a second driven shaft 71 and a fourth sprocket 72 provided on the second driven shaft 71;
[0050] A first transmission chain 53 is provided between the second sprocket 62 and the first sprocket 52;
[0051] A second transmission chain 64 is provided between the third sprocket 63 and the fourth sprocket 72:
[0052] There is one second sprocket 62 and it is arranged in the middle of the first driven shaft 61; there are two third sprockets 63 and they are symmetrically arranged on the first driven shaft 61;
[0053] The device has two support columns 9 provided front and rear, and an upper mounting plate and a lower mounting plate provided between the support columns 9; the device also has two support channel steels 10 provided front and rear, and an upper mounting plate and a lower mounting plate provided between the support channel steels 10; the first driven shaft 61 is rotatably provided between the upper mounting plates, and the second driven shaft 71 is rotatably provided between the lower mounting plates;
[0054] When the lifting mechanism 3 is in operation, the driving device 4 is first started, driving the driving shaft 51 in the driving sprocket assembly 5 to rotate, and the driving shaft 51 drives the first sprocket 52 to rotate, and the first sprocket 52 drives the second sprocket 62 on the first driven shaft 61 to rotate through the first transmission chain 53. At this time, the first driven shaft 61 rotates synchronously;
[0055] Then the two third sprockets 63 on the first driven shaft 61 rotate accordingly, and the third sprocket 63 drives the fourth sprocket 72 on the second driven shaft 71 to rotate through the second transmission chain 64. At this time, the second driven shaft 71 rotates synchronously, and the third sprocket 63 in the first driven sprocket assembly 6; the fourth sprocket 72 in the second driven sprocket assembly 7 is connected to the smoke control platform 2 through a rope, so the smoke control platform 2 can be raised and lowered by the rope.
[0056] Due to the configuration of the smoke control platform 2 in this device, to prevent the wheels of the smoke control platform 2 from slipping, the electric hydraulic pusher 8 and the brake system of the smoke control platform 2 are locked when the smoke control platform 2 is not being raised or lowered. This is achieved specifically through the electric hydraulic pusher 8 of this device, which is linked to the brake system of the smoke control platform 2. When the pusher is started, the brake system is triggered through a mechanical connection or electronic signal, causing the first driven sprocket assembly 6 and the brakes on the wheels of the smoke control platform 2 to lock. This is done to ensure that the smoke control platform 2 can remain stationary during the start-up process of the pusher, preventing the smoke control platform 2 from accidentally moving due to the action of the pusher.
[0057] When the first driven shaft 61 rotates, the speed detection device detects the rotation rate of the first driven shaft 61 and determines that the first driven shaft 61 has started to rotate, so a signal will be sent to the electric hydraulic pusher 8 at this time. At this time, the electric hydraulic pusher 8 will be closed, so that the brakes of the first driven sprocket assembly 6 and the smoke control platform 2 will be changed to an unlocked state, so that the smoke control platform 2 can be raised and lowered in the supporting channel steel 10.
[0058] The driving device 4 includes a motor 41, the output end of the motor 41 is connected to a reducer 42, and the output end of the reducer 42 is connected to the driving shaft 51. The motor 41 of this device is the power source, and the reducer 42 can make the smoke control platform 2 rise and fall more stably.
[0059] A fall arrester 11 is further provided near the top of the supporting channel steel 10 , and the fall arrester 11 is connected to the smoke control platform 2 via a steel cable.
[0060] The anti-fall device 11 of this device is connected to the smoke control platform 2 through a steel cable. The specific anti-fall method is: when an unexpected situation occurs during the operation of the smoke control platform 2, such as a sudden fall, the anti-fall device 11 can respond quickly and prevent the coke pushing car 2 from falling further through the stretching effect of the steel cable, thereby protecting the safety of the operator and equipment.
[0061] The arrester 11 typically has a trigger mechanism that automatically activates upon detecting abnormal falling speed or acceleration, ensuring the safety of the smoke control platform 2. However, the arrester 11 in this device utilizes the difference in falling speeds for self-control. A speed sensor is incorporated into the arrester 11. When the falling speed of the smoke control platform 2 exceeds a preset threshold, the sensor triggers the arrester 11, rapidly locking the cable and preventing further descent. This threshold is set at 0.95 m / s.
[0062] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
