Hereinafter, describe coke oven switchboard exchange tie rod transmission system of the present utility model in detail with exemplary embodiment with reference to the accompanying drawings.
Fig. 1 shows according to the installation plan view of an exemplary embodiment of coke oven switchboard exchange tie rod transmission system of the present utility model.Fig. 2 shows the side schematic view of Fig. 1.
As depicted in figs. 1 and 2, in an exemplary embodiment of the present utility model, coke oven switchboard exchange tie rod transmission system comprises four horn ring supports 1, is arranged on four horn rings 2 on four horn ring supports 1, the chain 3 coordinating with four horn rings 2, the first tie rod 4a being fixedly connected with the two ends of chain 3 respectively and the second tie rod 4b and anti-chain breakage emergency device.
Wherein, anti-chain breakage emergency device comprises the first static pulley 5a, the second static pulley 5b, the first pulley bracket 6a, the second pulley bracket 6b, metallic cable 7 and tightener 8.The first static pulley 5a is arranged on one end of the first pulley bracket 6a and is positioned at the formed arc of chain 3 outside, and the other end of the first pulley bracket 6a is fixedly mounted on four horn ring supports 1.The second static pulley 5b is arranged on one end of the second pulley bracket 6b and is positioned at the formed arc of chain 3 outside, and the other end of the second pulley bracket 6b is fixedly mounted on four horn ring supports 1.Metallic cable 7(for example, steel cable) one end is fixed on the first tie rod 4a, and the other end of metallic cable 7 is walked around the bottom of the first static pulley 5a race and the top of the second static pulley 5b race and is fixed on the second tie rod 4b upper successively, so that metallic cable 7 is in micro-tight state.And the race of the race of the first static pulley 5a and the second static pulley 5b and the gear teeth of four horn rings 2, in same plane, can be guaranteed through the metallic cable 7 of the first static pulley 5a and the second static pulley 5b in the same plane with chain 3 like this.Here, said micro-tight state is strained a little, but state laboriously not substantially.In the situation that fracture occurs the chain 3 coordinating with four horn rings 2, steel cable can play standby effect, replaces chain 3 to carry out transmission exchange, thereby can guarantee coke oven switchboard exchange tie rod transmission system stability and safety, moves.
In this exemplary embodiment, the first pulley bracket 6a consists of two the first sheet metals parallel to each other that are fixed on four horn ring support 1 both sides, and chain 3 can pass the gap between two the first sheet metals parallel to each other; The second pulley bracket 6b consists of two the second sheet metals parallel to each other that are fixed on four horn ring support 1 both sides, and chain 3 can pass the gap between two the second sheet metals parallel to each other.Chain 3 is made into motion by unaffected like this.Yet the utility model is not limited to this, for example, the first pulley bracket 6a and the second pulley bracket 6b also can be has chain by other type support in hole.
Two tighteners 8 are fixed on the two ends of metallic cable 7 on the first tie rod 4a and the second tie rod 4b respectively.Yet the utility model is not limited to this, for example, also cocoa for example, is fixed on the two ends of metallic cable 7 on the first tie rod 4a and the second tie rod 4b by alternate manner (, welding manner).
In this exemplary embodiment, the first static pulley 5a, the second static pulley 5b are single port static pulley.Yet the utility model is not limited to this, for example, also can be twoport static pulley or many mouthfuls of static pulley.In the situation that the first static pulley 5a and the second static pulley 5b are twoport static pulley, two metallic cables arranged side by side 7 can be set.
As shown in Figure 1, the length direction of the second pulley bracket 6b is preferably substantially vertical with the tangent direction of 3 mates of four horn rings 2 and chain, the length direction of the first pulley bracket 6a is preferably with the length direction of described the second pulley bracket 6b and is the acute angle (for example, the acute angle of 30～50 °) that is not more than 60 °.
For this exemplary embodiment, metallic cable 7 can be Φ 25 steel cables, and its length can be 4.5m; The first sheet metal and the second sheet metal can be the channel-section steel of 100mm, and its length can be 3m; The first static pulley 5a and the second static pulley 5b are single port static pulley, and its diameter is 100mm, and rated load is 150KN.
Below by the coke oven switchboard exchange tie rod transmission system of this exemplary embodiment is applied to, on the 6.25m of the coal plant stamp-charging coke switchboard of certain iron and steel enterprise, using effect of the present utility model is described.After coke oven switchboard exchange tie rod transmission system is installed, the metallic cable 7 of its anti-chain breakage emergency device is in micro-tight state.Its chain 3 is laid down to test to the emergent performance of coke oven switchboard exchange tie rod transmission system.In test run process, because metallic cable 7 is in micro-tight state, but its length is slightly longer than the chain at this place 3 all the time, so exchanging stroke while automatically exchanging can not cover completely, poor approximately 6～8mm, need manual crawl can cover a stroke, but site inspection coke-stove gas exchange rotary plug and waste gas are cut or polish jade with an emery wheel, coal gas sticks together and all puts in place, does not cause any harm.Visible, the coke oven switchboard exchange tie rod transmission system of this exemplary embodiment can play emergencing action completely.
In another exemplary embodiment of the present utility model, coke oven switchboard exchange tie rod transmission system comprises four horn ring supports, is arranged on four horn rings on four horn ring supports, the chain coordinating with four horn rings, the first tie rod being fixedly connected with the two ends of chain respectively and the second tie rod and anti-chain breakage emergency device.
Wherein, anti-chain breakage emergency device comprises static pulley group, pulley bracket, metallic cable (for example, steel cable) and two tighteners.Static pulley group comprises two static pulley that are set up in parallel, static pulley group is arranged on one end of pulley bracket and is positioned at the formed arc of chain outside, the other end of pulley bracket is fixedly mounted on four horn ring supports, and the race of two static pulley of static pulley group and the gear teeth of four horn rings are in same plane.One end of metallic cable is fixed on the first tie rod, and its other end walk around successively static pulley group two static pulley race and be fixed on the second tie rod, and metallic cable is in micro-tight state.That is to say, in this exemplary embodiment, be equivalent to anti-chain breakage emergency device and (for example only comprise a pulley bracket, as the second pulley bracket in Fig. 1), and one end of this pulley bracket form two static pulley (for example, in Fig. 1 the second pulley bracket away from one end of four horn ring supports on a static pulley arranged side by side with the second static pulley is installed again).Two tighteners are fixed on the two ends of metallic cable on the first tie rod and the second tie rod respectively.
For this exemplary embodiment, pulley bracket can consist of two sheet metals parallel to each other that are fixed on four horn ring support both sides, and chain can pass the gap between described two sheet metals parallel to each other.In addition, two static pulley can be single port static pulley.Yet the utility model is not limited to this.
To sum up, the utility model provides a kind of coke oven switchboard exchange tie rod transmission system that can move safely and steadly, is applicable to all coke oven exchange systems.
Although described the utility model with exemplary embodiment by reference to the accompanying drawings above, those of ordinary skills should be clear, in the situation that do not depart from the spirit and scope of claim, can carry out various modifications to above-described embodiment.
