The specific embodiment
With reference to accompanying drawing, the utility model is described further: the present invention is a frame 1 with an I-steel, matches with I-steel frame 1 to be provided with stationary jaw support 2 and movable jaw support 3, as shown in Figure 1.Stretch out two stationary jaws 4 on the stationary jaw support 2, stretch out two movable jaws 5 on the movable jaw support 3, the centre-to-centre spacing of two stationary jaws 4 and two movable jaws 5 is consistent with the centre-to-centre spacing of double center chain two chains 6, the symmetrical plane of I-steel frame 1 is consistent with the symmetrical plane of two stationary jaws 4 and two movable jaws 5, as shown in Figures 2 and 3.One end and the stationary jaw support 2 of frame 1 are connected as a single entity, movable jaw support 3 flexibly connects with I-steel frame 1 by a pair of front wheel 7 on the biside plate 20 that is installed in movable jaw support 3 and a pair of rear roller 8, and is provided with longitudinal separation between front wheel 7 and the rear roller 8.A pair of front wheel 7 on the movable jaw support 3 and a pair of rear roller 8 are located at the upper and lower both sides of the lower steel plate 9 of I-steel frame 1, and perhaps a pair of front wheel 7 on the movable jaw support 3 and a pair of rear roller 8 are located between the upper steel plate 10 and lower steel plate 9 of I-steel frame 1.Oil cylinder 11 utilizes sphere joint 12 to be connected with stationary jaw support 2, is buckled in by gland 13 on the annular edge of oil cylinder pressure cap 14, and restriction oil cylinder 11 can make oil cylinder 11 do low-angle swing again when moving.Oil cylinder piston bar 15 is connected with movable jaw support 3, and the end of oil cylinder piston bar 15 and movable jaw support 3 can utilize pin 16 to link together.By piston rod 15 pulling movable jaw supports 3, movable jaw support 3 is vertically seesawed along frame 1.Stationary jaw 4 can insert in the horizontal chain link 17 with movable jaw 5 cross sectional dimensions; The concave surface 19 that the stress surface of all claws all has a curved surface that protrudes with vertical chain link 18 to match can slippage so that block chain link 18 when stressed, the security when fully having guaranteed tight chain.The center line of oil cylinder 11 is on the symmetrical plane of two stationary jaws 4 and two movable jaws 5, parallel with the center line of double center chain two chains 6, and be higher than the plane at the center line place of double center chain two chains 6, do not interfere so that make piston rod 15 can stride across the scraper plate of double center chain drag conveyor.For preventing that movable jaw support 3 from occurring rotating in stressed back, the two inboard both sides with frame lower steel plate 9 that movable jaw support 3 is installed front and rear rolling wheel are matched in clearance.
Operation principle of the present utility model is as follows: double center chain chain 6 wants dismounting and the chain link of certain-length must be unclamped, and the method for unclamping is that the stationary jaw 4 of double center chain scraper chain disassembling and installing machine and movable jaw 5 are inserted in the ring of two chain links 17 of the certain-length of being separated by, and the distance between two chain links 17 is furthered.Because two scraper plates of double center chain drag conveyor are at a distance of nearer, the piston rod 15 of the oil cylinder 11 of the chain link that furthers can't not striden scraper plate.When piston rod 15 tension movable jaws 5, piston rod 15 acts on power F1 on the movable jaw support 3 and the counter-force f1 of 7 pairs of movable jaws 5 of double center chain chain has just formed a moment.In like manner, the power F1 that 12 place's oil cylinders 11 act on the stationary jaw support 2 in the sphere joint has also also formed a moment with the counter-force f1 of 7 pairs of stationary jaws 4 of double center chain chain.These two moments are not if manage to overcome, and stationary jaw 4 and movable jaw 5 all can overturn, and can't finish the task of the chain link 17 that furthers.
, stationary jaw 4 and I-steel frame 1 are connected as a single entity for this reason, load onto front wheel 7 and rear roller 8 on movable jaw support 3,1 the following of lower steel plate 9 of top and frame of front wheel 7 contacted, following and frame 1 the top of lower steel plate 9 of rear roller 8 contacts; 1 the following of upper steel plate 10 of top and frame of front wheel 7 contacted, and following and frame 1 the top of lower steel plate 9 of rear roller 8 contacts.Like this, front wheel 7 and rear roller 8 are subjected to the effect counter-force F2 of frame 1, the formed moment of this effect counter-force F2 just in time overcomes piston rod 15 and acts on the power F1 on the movable jaw support 3 and the moment that counter-force f1 produced of 7 pairs of movable jaws 5 of double center chain chain, as shown in Figure 5.In like manner, the active force f2 of front wheel 7 and 8 pairs of frames 1 of rear roller also forms a moment, and this moment has also just in time overcome in the sphere joint 12 place's oil cylinders 11 and acted on the power F1 on the stationary jaw support 2 and the moment that counter-force f1 produced of 7 pairs of stationary jaws 4 of double center chain chain.Like this, the moment that produced when furthering chain link 17 of movable jaw 5 and stationary jaw 4 all has been overcome.Movable jaw 5 and stationary jaw 4 all no longer produce upset under the active force of oil cylinder 11, thereby have finished the task of the chain link 17 that furthers.
