Embodiment
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 5, be the structural representation of an embodiment's of the utility model chain clasp deployed condition.As can see from Figure 5, chain clasp in the present embodiment comprises the first clip 1, the second clip 2 and connecting rod 3, wherein the first end of the first end of the first clip 1 and the second clip 2 can be fixedly connected with by bolt and nut (referring to Fig. 6), the second end of the second end of the first clip 1 and the second clip 2 carries out hingedly with the two ends of connecting rod 3 respectively, and the first clip 1 and the second clip 2 can rotate into closed state or deployed condition with respect to connecting rod 3.
As can be seen from Figure 6, the first clip 1 of the chain clasp of the present embodiment be connected clip 2 one ends and connect (being bolt 6 and tightening nut 7) by bolt and nut, the other end is connected with connecting rod by hinged mode, two clips all can rotate a certain angle with respect to connecting rod 3, therefore can launch very easily and closure when loading and unloading, clip is fitted with the flange fitting surface that will tighten as much as possible.
Connecting rod 3 has connected two clips, the bolt and nut that is fastenedly connected together with the clip the other end, can jointly realize reliable fastening effect to flange arrangement, and connecting rod 3 itself and the first clip 1 be connected clip 2 and all be connected, therefore the first clip 1 and the second clip 2 all can rotate in the circumferential plane of clip with respect to hinge point, thereby can locate exactly when assisting the first clip 1 and the second clip 2 closed, the through hole 11 of the first end of the first clip 1 is alignd with the through hole 4 of the first end of the second clip 2, facilitate the installation of bolt and nut.Bolt and nut only need to be arranged on the first end of two clips, and the quantity of the bolt and nut that therefore needs is also fewer, and dismounting and installation are all more convenient.
Can see in Fig. 6, in the hinge point of the first clip 1 and the second clip 2, can be connected with connecting rod 3 by bearing pin 5, like this, the first clip 1 and the second clip 2 all can rotate with respect to bearing pin 5.The axis of the chain clasp after the installation direction of bearing pin 5 and closure is parallel, and chain clasp can be alignd exactly, makes operator's mounting or dismounting work more convenient.Can also take other articulated manner in the hinge point of the first clip 1 and the second clip 2.
In order to tighten as much as possible flange arrangement, therefore preferably in the inboard of the first clip 1 and the second clip 2, draw-in groove 9 and draw-in groove 12 are set respectively due to chain clasp, the interior profile of draw-in groove 9 and draw-in groove 12 coordinates with the external frame of the flange arrangement that needs chucking.This cooperating structure can be guaranteed the effect that tightens, avoids wearing and tearing and noise occuring frequently bearing under alternate load and vibration, and the situation such as even come off occurs.
At the connection part of the bolt and nut shown in Fig. 6, can see that bolt and nut comprises two groups, these two groups of bolt and nuts are arranged symmetrically with on the axial direction of chain clasp, like this can be with the flange arrangement card of centre tighter, and stressed evenly.In addition, two groups of bolt and nuts are installed and removed in the same side, and mounting or dismounting are convenient, and workload is also less.Can also see in Fig. 6, at the first end of the first clip 1 and the first end of the second clip 2, recessed portion 8 and recessed portion 13 are set respectively all, and through hole 4 and through hole 11 are arranged in recessed portion 8 and recessed portion 13, then are fixed connection by bolt and nut.With the structure that the bolt and nut attachment portion of clip is designed to be recessed into, further dwindled on the whole shared space, make its more easily installation and removal in the compact tank of space layout.Certainly, recessed portion is not set, but the first clip be connected the projection that the first end of clip is provided with through hole and can realize too utilizing bolt and nut to be fixed the mode of connection, specifically can be with reference to mode shown in Figure 2.
Provided a kind of way of realization of connecting rod 3 in Fig. 5, the split type member of two connecting plates that namely are arranged symmetrically with on the axial direction of chain clasp, this split type member manufacturing ratio is easier to, and also can adopt the connecting rod (not shown) of integrated member formula.
In the embodiment shown in fig. 6, can also on the first clip 1 and the second clip 2, through hole 10 be set, be equivalent to auxiliary hole, round steel can be inserted this through hole and rotate chain clasp.
The embodiment of the multiple chain clasp of above-mentioned introduction can be applied in concrete pumping system, in one embodiment, concrete pumping system comprises piston, pumping master cylinder, carries cylinder and tank, the pumping master cylinder utilizes the described piston of hydraulic driving reciprocating in described conveying cylinder, described tank is the intermediate connector of described pumping master cylinder and described conveying cylinder, also comprise foregoing chain clasp embodiment, this chain clasp is in clamping connection the flange arrangement of described pumping master cylinder and described piston.Operator are when specific operation, the bolt and nut that can become flexible two clip one ends in narrow tank opens two clips of chain clasp, when mounted, two clips can be opened and be buckled on the flange arrangement of pumping master cylinder and piston, then bolt is inserted in the through hole of two clip one ends, the tightening nut of screwing on again, in the process of tightening, need not manually adjust the position of chain clasp and flange arrangement, the fitting surface of chain clasp and flange can be adjusted to the state of being adjacent to automatically, therefore assembles very convenient.
Should be noted that at last: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can modify or the part technical characteristics is equal to replacement embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope that the utility model asks for protection.
