In one embodiment, have the interval evenly to arrange on the operating handle, and the spacing of selected pin-and-hole can be regulated a plurality of pin-and-holes of connection power subtly.
In another embodiment, this device also comprises exceeding in order to the rotation that stops first suspension hook and gives fixed angular range, thereby makes always the keep up suspension hook guard in bevelled orientation of first suspension hook, and this guard is connected on the adaptor union.
In another embodiment, above-mentioned suspension hook guard in order to the motion of restriction suspension hook takes the shape of the letter U, and it surrounds first suspension hook.
By below in conjunction with the detailed description of accompanying drawing, can be expressly understood above-mentioned and other purpose, feature and advantage of the present invention to most preferred embodiment.In the accompanying drawing:
Fig. 1 is the block diagram that cuts of part, and its expression is connected in the connecting device on the adaptor union of flexible discharging hose of the below that is positioned at the silo input pipe, and imaginary line is represented discharging hose;
Fig. 2 is the block diagram that decomposes, and for clarity sake, has taken apart waving cover, second suspension hook and operating handle;
Fig. 3 is the part block diagram of the connecting device of remodeling, and the suspension hook guard that expression is connected on the adaptor union surrounds first suspension hook, to limit the scope that it rotates;
Fig. 4 is a front elevation, and the expression connecting device is in the release position, and this moment, adaptor union and input pipe left;
Fig. 5 is the view that is similar to Fig. 4, but the expression connecting device is in control position, and this connecting device makes adaptor union and input pipe keep air-tightness to be connected.
Referring to Fig. 1, expression is according to connecting device of the present invention among the figure, and it is the mode to get loose easily easily, the flexible discharging hose 10 of discrete material trailer is connected on the input pipe 12 of fixing silo.Discharging hose 10 has a fixed end, and it is fixed on the transport box of trailer (for not shown for simplicity).On the joints of rigid pipes 14 of the elongated end of formation discharging hose 10 oral area 14a is arranged, it is the flange of a circle elastically deformable normally.Input pipe 12 hangs from above and is connected in fixedly silo (be also expression for simplicity), and it has upwards, outward-dipping flange 12a, has formed the conical end 12b of input pipe 12.If adaptor union 14 connects airtight with input pipe 12, conical end 12b just can be close on the oral area 14a.
Can see that this connecting device also comprises first and second suspension hooks 20,22, each suspension hook has pawl 20a or 22a at its far-end, and these two pawls can engage with the flange 12a of input pipe 12.The near-end of first suspension hook 20 is connected with hinge bolt 24 and waves on the cover 16, can rotate on the facade perpendicular to the pivot center that waves cover 16.Under the situation of first suspension hook 20 and flange 12a disengagement, because action of gravity, first suspension hook 20 can automatically rotate to clockwise direction, and the C.C.W. of first suspension hook rotates then will be by operator's M/C.
Just as illustrated in fig. 1 and 2, operating handle 26 is installed in the pivotally attached form on the diametric(al) position relative with first suspension hook 20 and waves on the cover 16, makes the handle 26 can be with manually rotating between release position and locked position.A hinge hole 26a and a plurality of is arranged on the operating handle 26,3 pin-and-hole 26b for example, these holes are evenly distributed along the length of handle, so that the spacing of selected pin-and-hole can be regulated connection power subtly.The stay bearing plate 28 of pair of parallel from waving the protrusion radially outward of cover 16, has a through hole 30 on the every stay bearing plate, the hinge hole 26a that hinge bolt 32 passes operating handle 26 inserts in these two through holes.There is screw thread the end of hinge bolt 32, so that be connected with nut 34, takes off to prevent hinge bolt 32.
Can see that second suspension hook 22 is connected on the operating handle 26 by means of pivot pin 36 with its near-end, can rotate, said pivot pin 36 passes the pivot hole 22b of second suspension hook 22 and a pin-and-hole 26b on the operating handle 26, and is connected with nut 38 with screw thread.Distance between the axis of the far-end of second suspension hook 22 and hinge bolt 32, promptly " the effectively spacing " of second suspension hook can change by pivot pin 32 is inserted another pin-and-hole 26b again from a pin-and-hole 26b extraction.In other words, when pivot pin 36 cooperated with uppermost pin-and-hole, effectively spacing was the longest.On the other hand, if pivot pin 36 inserts nethermost pin-and-hole, then effectively spacing is the shortest.Can infer easily that adaptor union 14 the connection power on the input pipe 12 of being pressed in will be along with the change of effective spacing of second suspension hook 22 and changed.Therefore, can regulate connection power by the effective spacing that changes second suspension hook 22 by operator's requirement.Second suspension hook 22 is done longlyer than first suspension hook 20, so that for a change effective spacing is allowed some leeway.Can select the length of second suspension hook 22 like this, make when operating handle 26 is in locked position, second suspension hook 22 can give adaptor union 14 pressurizations facing to input pipe 12 with adjustable connection power, connects to guarantee the no leak between them.In addition, the spacing of each pin-and-hole 26b is preferably arranged all even narrowlyer, so that can regulate connection power subtly.
Referring to Fig. 3, wherein represented the connecting device of remodeling, wherein suspension hook guard 40 is fixed on the position between the oral area 14a that waves cover 16 and adaptor union 14.Guard 40 is used to stop suspension hook 20 to exceed predetermined angular range around the rotation of pivot, thereby makes the first suspension hook 20 bevelled direction that always keeps up.This makes the operator needn't catch first suspension hook 20 to make it to anticlockwise motion when finishing the operation that adaptor union 14 and input pipe 12 are linked together.Though also can adopt the suspension hook guard of other type according to the design of invention,, suspension hook guard 40 preferably takes the shape of the letter U, and surrounds first suspension hook 20, so that restriction suspension hook motion angle.
In operation, if adaptor union 14 keeps breaking away from input pipe 12 as shown in Figure 4, then first and second suspension hooks 20,22 do not mesh with the flange 12a of pipe 12.In such released state, first suspension hook 20 is to lean against on the suspension hook guard 40 with the acutangulate position of the axis of adaptor union 14, and 22 on second suspension hook is in random site, and operating handle 26 is in the release position.When needs linked together adaptor union 14 and input pipe 12, the operator must catch adaptor union 14 with the right hand, then, adaptor union was contacted with pipe 12, after this, made first suspension hook 20 hook flange 12a.Next step places the pawl 22a of second suspension hook 22 on the flange 12a, and is last, catches operating handle 26 with left hand, and it is rotated to anticlockwise direction around pivotal axis, enters locked position.As shown in Figure 5, when handle 26 rotates in this way, adaptor union 14 will be pressed on the pipe 12 securely, so that the oral area 14a of adaptor union 14 and manage and form air-tightness between 12 the conical end face 12b and connect.
Though in conjunction with the embodiments disclosure and description the present invention, be noted that those skilled in the art can make various changes and modifications to the present invention in not breaking away from the present invention's design scope defined by the claims.
