Therefore, need to develop a kind of new structure, realize side door and the replacing flashboard of opening preventer fast, reach time saving and energy saving object, to reduce labour intensity, improve operating efficiency.
Utility model content
The purpose of this utility model is to provide a kind of ram preventer roller type side door mechanism, and solve prior art when changing the glue core of ram preventer, dismounting is inconvenient, wastes time and energy, ineffective problem.
The technical scheme that the utility model adopts is, a kind of ram preventer roller type side door mechanism, comprises preventer housing, is respectively arranged with a side door outside the both sides flashboard of preventer housing, and the side door structure of both sides is symmetrical; Preventer housing is provided with guide rail, side door is provided with roller, roller rolls along guide rail and drives side door rectilinear movement;
The contact surface that preventer housing both sides are corresponding with this side side door respectively is respectively provided with a through hole, and namely preventer housing is large semicircle through hole, and side door is small semicircle through hole, in the large semicircle through hole of preventer housing, be provided with lock shaft.
Ram preventer roller type side door mechanism of the present utility model, is further characterized in that:
Lock shaft is the cylinder of large semicircle, and its axial plane is less than face, diameter place.
When the small semicircle through hole of side door aligns with the large semicircle through hole of preventer housing and forms complete through hole, the axial plane of lock shaft is positioned at clamping position, and side door and preventer housing are in locking state;
When the axial plane of lock shaft is positioned at released position, side door and preventer housing are in released state.
The beneficial effects of the utility model are, semicircular through hole is respectively arranged with in the junction of ram preventer housing and side door, in the half-round cross hole of housing, locking pin is installed, locking pin can rotate in through hole, when the semi-circular through hole of side door is alignd with the semi-circular through hole of housing, rotational lock pin, can utilize locking pin to be connected together with side door by housing.Meanwhile, ram preventer is provided with guide rail, side door is provided with pulley, side door, along slide, when when rotational lock pin, side door and housing unlock, can pull out along guide rail by pulley, by flashboard pull-out, can realize the quick-replaceable of flashboard.This mechanism operation is easy to be laborsaving, and structure is simple, effectively can reduce the time that flashboard is changed.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figure 1, Figure 2, Fig. 3, Fig. 4, Fig. 5, the structure of the utility model device is,
Comprise preventer housing 1, outside the both sides flashboard 6 of preventer housing 1, be respectively arranged with a side door 4, side door 4 symmetrical configuration of both sides; Preventer housing 1 is provided with guide rail 5, side door 4 is provided with roller 3, roller 3 rolls along guide rail 5 and drives side door 4 to move linearly;
The contact surface that preventer housing 1 both sides are corresponding with this side side door 4 respectively is respectively provided with the through hole of an approximate half-circular, namely preventer housing 1 is large semicircle through hole, side door 4 is small semicircle through hole, both snap together formation full circle at correspondence, (in embodiment, each two groups of left and right forms four groups of complete through holes altogether), in the large semicircle through hole of preventer housing 1, lock shaft 2 is installed, lock shaft 2 can rotate in the large semicircle through hole of preventer housing 1, lock shaft 2 is the cylinder of large semicircle, its axial plane 2.1 is less than face, diameter place, the section area of lock shaft 2 is identical with the large semicircle via area of preventer housing 1.
When side door 4 is moved into and preventer housing 1 close contact, when the small semicircle through hole of side door 4 aligns with the large semicircle through hole of preventer housing 1 and forms complete circular hole, rotation lock mandrel 2, during the clamping position that the axial plane 2.1 of lock shaft 2 is rotated to shown in Fig. 2 or Fig. 3, side door 4 and preventer housing 1 are locked, and side door cannot outwards movement;
When the axial plane 2.1 of lock shaft 2 rotates to the released position shown in Fig. 4 or Fig. 5, (namely the main body of lock shaft 2 forwards large semicircle through hole side to), side door 4 and preventer housing 1 unlock, and roller 3 rolls along guide rail 5, and side door 4 outwards can move along guide rail 5 relative to preventer housing 1.
The operating principle of the utility model device is,
During original state, the axial plane 2.1 of lock shaft 2 is in the clamping position shown in Fig. 2 or Fig. 3, and now side door 4 and housing 1 are locked, and preventer normally works; When needing the flashboard 6 changing ram preventer, first rotation lock mandrel 2, its axial plane 2.1 is made to rotate to the released position shown in Fig. 4 or Fig. 5, side door 4 and housing 1 unlock, now side door 4 is pulled out, roller 3 on side door 4, along the guide rail 5 be fixed on side door 4 to outer rolling, until flashboard 6 is deviate from completely in preventer housing 1, now can carry out the replacing of flashboard 6.
After flashboard 6 has been changed, side door 4 is pushed preventer housing 1 along guide rail 5, until the small semicircle through hole of side door 4 aligns with the large semicircle through hole on preventer housing 1, rotation lock mandrel 2, its axial plane 2.1 is made to be in the clamping position shown in Fig. 2 or Fig. 3, lock by side door 4 and preventer housing 1, preventer can normally work.
Device of the present utility model, ram preventer adds a set of roller type side door mechanism, and only need rotation lock mandrel just can realize locking and the unblock of side door and preventer housing, when being pulled out by side door, side door is along guide rail to outer rolling; This mechanism operation is laborsaving, easy, and structure is simple, effectively can reduce the time changed needed for flashboard blowout prevention flashboard.
