Abstract
The utility model discloses a crusher inspection door locking device, which comprises a pair of locking buckle lug plates fixed on an inspection door and a locking head fixed on a door frame. The two locking buckle lug plates are T-shaped and are fixedly welded parallel to the inspection door; and the locking head is hinged with the lug plates fixed on the door frame through pin shafts, the pin shafts are connected with pressing bolts in the axial direction and the vertical direction, the pressing bolts are movably connected with pressing nuts through threads, one ends of the pressing nuts are provided with a rotating handle, and the pressing nuts are provided with a plane capable of being buckled with the locking buckle lug plates. By adopting the rotary locking structure with the locking head capable of rotating universally and the locking buckle lug plates, the opening and closing can be facilitated, the locking device is firm and reliable after being closed, the inspection door can be opened with no needs for other tools, the maintenance time can be greatly saved, and the use efficiency of equipment can be increased.
Description
Technical field
The utility model belongs to door lock and manufactures and designs the field, and the locking device that especially belongs to the frame for movement door manufactures and designs, the locking device that particularly is made up of snap close otic placode and tapered end.
Background technology
Manufacturing and designing of various structure doors usually arranged in the frame for movement, and inspection door is common structure in the disintegrating machine of mining machinery, because the bump of material after the crusher in crushing, inspection door needs firmly locking device easily.
Impact breaker is a kind of crushing mechanism that utilizes impact energy to come broken material.When material gets into the bar active region; Receive high speed impact and the fragmentation of bar; And make broken material tangentially throw to the counterpunch board of the crusher chamber other end at a high speed, be broken once more, bounce back into the bar active region from counterattack face again then and continue the repetition said process.In coming and going the way, the storeroom effect that runs foul of each other in addition.Because material receives the strike of bar, and the collision between mutually of the impact of counterpunch board and material, material constantly produces the crack, and is loose and cause pulverizing.Design is on casing usually for inspection door, and material impacting is frequent, adopts conventional locking device fragile, also relates to opening making things convenient for problem.
Summary of the invention
The utility model discloses a kind of disintegrating machine inspection door locking device according to the deficiency of prior art, and the problem that the utility model will solve is can conveniently open, close and firm locking device through a kind of.
The utility model is realized through following technical scheme.
Disintegrating machine inspection door locking device is made up of with the tapered end that is fixed on the doorframe the snap close otic placode that is fixed on the inspection door, and said snap close otic placode is " Γ " shape, has a pair of " Γ " shape snap close otic placode parallel fixing with the inspection door welding; Said tapered end is hinged with the otic placode that is fixed on the doorframe through bearing pin; The axial vertical direction of bearing pin connects hold-down bolt; Hold-down bolt and clamp nut flexibly connect through screw thread, and clamp nut one end has rotary handle, and clamp nut has the plane that can withhold the snap close otic placode.
For preventing that bearing pin from dislocating in the knockout process in vibration, in the bearing pin lower end split pin is arranged, the other end has convexity.
During the shut down inspection door, with tapered end pull-up upset, a transverse plane of clamp nut is withheld on snap close otic placode a pair of stupefied, rotates the rotary handle clamp nut of screwing and can close and lock inspection door.During unlatching, rotate rotary handle and unclamp clamp nut, upset is left the snap close otic placode and can be opened inspection door.
The helpfulness of the utility model; The utility model adopt can universal rotation tapered end cooperate the rotary locking structure with the snap close otic placode; Unlatching, shutoff operation are conveniently; It is solid and reliable that locking device cuts out the back, need not just can open inspection door by other instruments, practiced thrift the repair time greatly and improved the equipment service efficiency.
Description of drawings
Below in conjunction with the description of drawings and the specific embodiment the utility model is further specified.
Fig. 1 is the utility model locking device structure sketch map;
Fig. 2 is the utility model locking device lock head structure sketch map;
Fig. 3 is the utility model locking device snap close otic placode structural representation;
Fig. 4 is that the utility model locking device is at impact breaker final assembly position view.
Among the figure, the 1st, tapered end, the 2nd, clamp nut, 2a are clamp nut snap close planes, the 3rd, spanner; The 4th, hold-down bolt, the 5th, bearing pin, 5a are the doorframe otic placodes, the 6th, split pin, 6a is protruding; The 7th, snap close otic placode, 7a are that the snap close otic placode is stupefied, the 8th, and upper box assembly, the 9th, middle casing assembly, the 10th, preceding inspection door; The 11st, back inspection door, the 12nd, runner assembly, the 13rd, lower box assembly, the 14th, feed hopper.
The specific embodiment
Through the specific embodiment and accompanying drawing the utility model is further specified below.Embodiment is used to explain the utility model, limits the utility model never in any form.
In conjunction with Fig. 1 to Fig. 4.
As shown in the figure, disintegrating machine inspection door locking device is made up of with the tapered end 1 that is fixed on the doorframe the snap close otic placode 7 that is fixed on the inspection door, and snap close otic placode 7 is " Γ " shape, has a pair of " Γ " shape snap close otic placode 7 parallel fixing with the inspection door welding; Tapered end 1 is hinged with the otic placode 5a that is fixed on the doorframe through bearing pin 5; Bearing pin 5 axial vertical direction connect hold-down bolt 4; Hold-down bolt 4 flexibly connects through screw thread with clamp nut 2, and clamp nut 2 one ends have rotary handle 3, and clamp nut 2 has the plane 2a that can withhold snap close otic placode 7.Bearing pin 5 one ends have and prevent that split pin 6, one ends of dislocating from having protruding 6a.
During installation, with any one of one of them bulb screw-in spanner 3, again spanner is passed the through hole on the clamp nut 2 earlier, again another bulb is screwed in the other end of spanner 3, again hold-down bolt 4 is screwed in the screwed hole of clamp nut 2 a little.As shown in Figure 1, couple together with bearing pin 5 hold down gag that will before assemble and the otic placode 5a that strikes back on the broken casing, bearing pins are pinned in split pin 6, prevent string.
During use, the shut down inspection door, with tapered end 1 pull-up upset, a transverse plane 2a of clamp nut 2 withholds on a pair of stupefied 7a of snap close otic placode 7, rotates rotary handle 3 clamp nut 2 of screwing and can close and lock inspection door.During unlatching, rotate rotary handle 3 and unclamp clamp nut 2, upset is left snap close otic placode 7 and can be opened inspection door.
The utility model simplicity of design, easy operating need not just can open inspection door by other instruments, has practiced thrift the repair time greatly.
