Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1 and Figure 2, weight method graphite removing apparatus disclosed by the invention, the braking mechanism 5 comprising erecting frame 1, weight cylinder 2, drum shaft 3, weight 201, driving mechanism 4 and act on drum shaft 3, described drum shaft 3 is arranged on erecting frame 1, described weight cylinder 2 is installed on drum shaft 3, and described driving mechanism 4 is in transmission connection with drum shaft 3, and described weight cylinder 2 is wound with lifting rope 202, described lifting rope 202 one end is connected with weight cylinder 2, and the other end is connected with weight 201.
The principle of work of this device is as follows:
First erecting frame 1 is moved to upcast 11 place needed except graphite, weight 201 is made to aim at upcast 11 mouth of pipe, take-off the brake mechanism 5, weight 201 falls into upcast 11 under gravity, the graphite of the accumulation in upcast 11 is impacted, to be wound on weight cylinder 2 lifting rope 202 along with unclamping gradually the whereabouts of weight 201 simultaneously, when lifting rope 202 discharges completely and tightens, weight 201 stops falling, start driving mechanism 4 afterwards, drive roller shaft 3 rotates, weight cylinder 2 is driven to rotate, lifting rope 202 is wound on weight cylinder 2 gradually, weight 201 upwards promotes, after weight 201 is thus lifted to position, stop the operation of driving mechanism 4 and clamp braking mechanism 5, and then take-off the brake mechanism 5, weight 201 is fallen, so repeatedly can complete the removing of upcast 11 graphite.Certainly, also by other modes, weight 201 is made to stop falling, before discharging completely at lifting rope 202, braking mechanism 5 is used to brake, so before weight 201 falls, the length that lifting rope 202 is wound in weight cylinder 2 is more than or equal to the height of drop of weight 201 in cleaning graphite process.
At this, now braking mechanism 5 and driving mechanism 4 are reciprocal interlocking state.Namely driving mechanism 4 obtains electric, and braking mechanism 5 is in open mode; On the contrary, driving mechanism 4 dead electricity, braking mechanism 5 is in clamped condition.Like this thus effectively ensure that the stable and security that weight runs.And lifting rope 202 preferably adopts iron chains to make, also can adopt the materials such as steel cable, its length need ensure that weight 201 can to fall to behind the growth of graphite district of upcast 11 also remaining certain distance (being generally 500mm).Keyway can be adopted between weight cylinder 2 with drum shaft 3 to be connected, expansion sleeve also can be adopted to connect.
Braking mechanism 5 can select strap braking device, disc brake apparatus or block brakes etc., and as optimal way, described braking mechanism 5 comprises block brake 501 and brake wheel 502, described brake wheel 502 is installed on drum shaft 3, described block brake 501 is arranged on erecting frame 1, and described brake wheel 502 is between the brake pad of block brake 501.
When needs are braked, the brake pad clamping brake wheel 502 of block brake 501, produces braking effect, drum shaft 3 is no longer rotated.For ease of installing block brake 501, preferably brake wheel 502 is arranged at the other end relative to driving mechanism 4 on drum shaft 3.
Because weight 201 has larger weight, and it is when doing upward movement, speed can not be too fast, direct employing motor drive roller shaft 3 is rotated and is difficult to reach requirement, so, comprise motor 401 and step-down gear 402 as driving mechanism described in optimal way 4, described motor 401 is in transmission connection with step-down gear 402, and the output shaft axle 3 of described step-down gear 402 is in transmission connection.Simultaneously the Main Function of step-down gear 402 reduces rotating speed to improve output torque, so can complete the effect promoting weight 201 preferably.
In such scheme, if weight 201 directly falls from weight cylinder 2, be not easy to operation implement, for addressing this problem, as optimal way, described erecting frame 1 is provided with guide support arm 701, described guide support arm 701 is provided with guide deflection sheave 7, described lifting rope 202 is walked around guide deflection sheave 7 and is fixedly connected with weight 201.
After this arranges guide deflection sheave 7, weight 201 can complete rising and descending motion immediately below guide deflection sheave 7, thus only need be displaced into directly over upcast 11 by guide deflection sheave 7, can carry out the graphite cleaning work of upcast 11.
For ease of adjustment guide deflection sheave 7 position, make it corresponding with upcast 11 mouth of pipe, as optimal way, described guide support arm 701 is telescopic boom, and described guide support arm 701 is connected with the telescoping drive mechanism 702 for driving guide support arm 701 to make stretching motion.
So-called telescopic boom, as the term suggests be the arm structure can making stretching motion, it includes the structure types such as sliding and sleeve type, is connected by the drive units such as oil cylinder, so it just can be driven to stretch with the movable block of telescopic boom.When carrying out except graphite work, just driving telescopic boom to stretch out by telescoping drive mechanism 702, making guide deflection sheave 7 just to upcast 11; And when not working, drive telescopic boom to regain by telescoping drive mechanism 702.Described telescoping drive mechanism 702 can adopt cylinder, hydro-cylinder etc. structure.
When adopting weight method except graphite, due to weight 201 drop to terminal time, weight 201 pairs of lifting rope 202 surging forces are larger, add high temperature to act on lifting rope 202, be easy to cause the lifting rope 202 of weight 201 to rupture, weight 201 causes damage to carbonizing chamber after falling into carbonizing chamber, affect coke oven normal production operation, for addressing this problem, as optimal way, this weight method graphite removing apparatus is provided with buffering system, described buffering system comprises buffer roller 8 and buffer gear 9, described buffer gear 9 is relative with erecting frame 1 fixing, described buffer roller 8 is installed on drum shaft 3, described buffer roller 8 is wound with snub rope 801, one end, described snub rope 801 is connected with buffer roller 8, the other end is connected with buffer gear 9, after weight 201 is dropped through upcast growth of graphite district, and before lifting rope 202 discharges completely, the winding direction of described snub rope 801 on buffer roller 8 is contrary with the winding direction of lifting rope 202 on weight cylinder 2, and is in tensioned state.
Buffer gear 9 is made to play its effect, weight 201 just must ensure when will drop to lower-most point, described snub rope 801 tightens just, that is when not arranging buffering system, generally discharged by lifting rope 202 and tightened control weight 201 no longer to fall, and after buffering system is set, just needs snub rope 801 is tightened and under buffer gear 9 acts on, control weight 201 and stop falling.So after weight 201 is dropped through upcast growth of graphite district, and before lifting rope 202 discharges completely, the winding direction of described snub rope 801 on buffer roller 8 is contrary with the winding direction of lifting rope 202 on weight cylinder 2, and is in tensioned state.In other words, weight 201 complete once hit cleaning after, make snub rope 801 lifting rope 202 discharge completely tighten before just tighten, buffer gear 9 is played a role.Because snub rope 801 will make weight 201 stop falling, so now the winding direction of snub rope 801 must be contrary with lifting rope 202 winding direction.Snub rope 801 tensioned state described here, namely refers to that snub rope 801 is wound on buffer roller 8 to greatest extent, and also exceptionally straight in buffer roller 8 snub rope 801 between buffer gear 9.The mode that can reach above-mentioned requirements is a lot, when specifically arranging snub rope 801, weight 201 first can be transferred to suitable location, and ensure that lifting rope 202 does not discharge completely, by snub rope 801 reverse-winding on buffer roller 8, tighten and be connected with buffer gear 9, but snub rope 801 length at least ensures it is the half of now weight 201 height of drop.
And as optimal way, when weight 201 does not fall, described snub rope 801 is wound on buffer roller 8, and be in tensioned state, the winding direction of described snub rope 801 is identical with the winding direction of lifting rope 202.And after weight 201 completes once strike cleaning, described snub rope 801 reverse-winding on buffer roller 8, and is in tensioned state, weight 201 is made to stop falling under the effect of buffer gear 9.
When weight 201 falls, because snub rope 801 winding direction is identical with lifting rope 202 winding direction, so, snub rope 801 unclamps gradually, when weight 201 drops to a half, along with the scrolling of buffer roller 8, snub rope 801 again progressively reverse-winding on buffer roller 8; At weight 201 through upcast 11 growth of graphite district and when arriving lower-most point, snub rope 801 tightens, under the effect of buffer gear 9, reduce weight 201 speed gradually, thus slow down the impact to lifting rope 202 when weight 201 drops to terminal.If now identical with weight cylinder 2 diameter with regard to buffer roller 8, then require when weight 201 does not fall, snub rope 801 length be wound on buffer roller 8 is the half of weight height of drop.And if the diameter of buffer roller 8 is the half with weight cylinder 2 diameter, then half can shorten on the basis of the above again in snub rope 801.This mode effectively can reduce the length of snub rope 801, prevents together with it is hooked on miscellaneous part.Certainly, when this just ensures that weight 201 drops to lower-most point, make a kind of mode that snub rope 801 tightens, also can adopt additive method, such as when weight 201 does not fall, snub rope 801 is not wound on buffer roller 8, in weight 201 dropping process, snub rope 801 is wound on buffer roller 8 gradually, and when weight 201 drops to lower-most point, snub rope 801 is wound on buffer roller 8 to greatest extent, and it can be made to be in tensioned state.
As mentioned above, buffer gear 9 can adopt cylinder, the structures such as spring, and as optimal way, described buffer gear 9 comprises overcoat 901, pulling shaft 902 and spring 903, described overcoat 901 is fixedly connected with erecting frame 1, described pulling shaft 902 bottom has annular flange flange 904, described overcoat 901 top has opening, the annular flange flange 904 of described pulling shaft 902 is positioned at overcoat 901, overcoat 901 is extended by the opening at overcoat 901 top in described pulling shaft 902 upper end, described spring 903 is positioned at overcoat 901, and spring 903 is set on pulling shaft 902, the opening diameter at described overcoat 901 top is less than spring 903 external diameter, annular flange flange 904 diameter of described pulling shaft 902 is greater than spring 903 external diameter, described snub rope 801 is connected with pulling shaft 902 upper end.
When snub rope 801 tightens, upwards lift pulling shaft 902, under the effect of the annular flange flange 904 of pulling shaft 902, spring 903 compresses, thus produces shock absorption power.The opening diameter at overcoat 901 top is less than spring 903 external diameter, be to prevent spring 903 from jumping out overcoat 901, and annular flange flange 904 diameter of pulling shaft 902 is greater than spring 903 external diameter, is to make pulling shaft 902 can make its extrusion spring 903 when upwards lifting.
Mobile mounting rack 1 during for ease of using, as optimal way, this weight method graphite removing apparatus also comprises coke-oven locomotive 10, and described erecting frame 1 is arranged on coke-oven locomotive 10.
So, i.e. Mobile mounting rack 1 very easily, moves to weight 201 just to the position of upcast 11 mouth of pipe, thus increases work efficiency.In addition, buffer gear 9 can be arranged on coke-oven locomotive 10, make its position corresponding better with buffer roller 8.
When weight 201 falls, driving mechanism 4 can be driven to follow weight cylinder 2 and rotate, thus fall to causing obstruction to weight 201, for addressing this problem, as optimal way, described driving mechanism 4 is in transmission connection by clutch coupling 6 and drum shaft 3.Adopt clutch coupling 6, when weight 201 promotes, the output terminal of drum shaft 3 with driving mechanism links together by clutch coupling 6, driving mechanism 4 drives cylinder 2 axle to rotate, and when weight 201 falls, drum shaft 3 is separated with the output terminal of driving mechanism by clutch coupling 6, driving mechanism 4 is not along with drum shaft 3 rotates, thus the resistance effectively decreased in weight 201 dropping process, increase the shock action of weight 201 pairs of graphite, ensure that weight 201 cleans effect.
