Description
Technical field
The invention belongs to building doors and windows technical field, relate to a kind of folded door, especially relate to a kind of anti-whereabouts safety guard of bolt type upper folding door, this device is arranged at the arranged on left and right sides of folded door bottom bracket, is mainly used in the anti-whereabouts safeguard protection of folded door.
background technology
Along with economic develop rapidly, the increasing rapidly of the industries such as air-transport industry and Shipping, the therefore also corresponding increase of demand of the sand blasting room of various large-scale hangar doors and shipyard.Because this type of door opening size is larger, this class door all adopts folded door in the market.Upper folded door is comprised of institutes such as PVC cord, some cord frameworks, bottom bracket, door lifter, wire rope and guide rails, as Fig. 1.PVC cord is fixed on some cord frameworks and bottom bracket more uniformly, at the two ends of cord framework and bottom bracket, being provided with directive wheel can move up and down along the guide rail on door opening column, while opening the door, door lifter starts, wirerope-winding is on the reel of door lifter, drive bottom bracket and cord framework upwards to stack successively, realize the unlatching of door.But there are some disadvantageous factors in this class door:
1, because door needs repeatedly opening and closing Reusability, after long-term use, wire rope there will be wearing and tearing or aging phenomenon, simultaneously because the size of door is larger, the weight of door is corresponding larger, when steel rope abrasion or be aged to and to a certain degree there will be fracture, once there is fracture, door will fall down, and consequence is serious.
2, the in the situation that, a door body very large at blast being closed, cord is because of blast flexural deformation, can drive bottom bracket along the side guide slippage that makes progress, and makes a body bottom occur gap; Blast diminishes, and bottom bracket is because Action of Gravity Field falls along side guide.Therefore, bottom bracket can change and upper and lower play along with blast, the sealing effectiveness of folded door in impact.
Summary of the invention
Object of the present invention is exactly for above-mentioned the deficiencies in the prior art, provides a kind of door lifter that can either make laborsaving, can when blast is larger, stop again the anti-whereabouts safety guard of bolt type upper folding door sliding on folded every body.
The technical solution used in the present invention is as follows:
A kind of anti-whereabouts safety guard of bolt type upper folding door, it comprises the wire rope that connects upper folded door bottom bracket and cord framework, the one or both ends that it is characterized in that described bottom bracket are provided with safety guard, described safety guard comprises guide, latch, guide pad, guide and guide pad are fixedly mounted on bottom bracket, two latch one end are slidably mounted in guide, and be provided with a plurality of strut rails that coordinate with latch on the upper folded door guide rail of this end, jack, pit or projection, two latch one end are slidably mounted in the hole on guide pad, described wire rope passes between two latches, on two latches, position-limit mechanism is installed, described position-limit mechanism one side is located by wire rope, opposite side withstands on stage clip one end, the other end of stage clip withstands on guide pad.
Described position-limit mechanism comprises two guide pin bushings that are arranged on two latches, between two guide pin bushings, position-limited wheel is installed, and position-limited wheel and described wire rope touch.
Described compression spring sleeve is contained on latch, and the adjusting nut that regulates stage clip elastic force is installed on latch.
Screw mandrel is arranged in the stage casing of described latch, and adjusting nut is arranged on this screw mandrel, and described stage clip is between adjusting nut and guide pad.
The bottom of described guide rail is provided with the stop matching with described latch end.
Beneficial effect of the present invention has:
1, this anti-whereabouts safety device, in guide rail bottom without cross bar is set, has feature simple in structure, easy for installation.
2, this anti-whereabouts safety device adopts, in guide rail bottom, stop is set, and can stop the upper cunning of folded every body, good sealing effect when blast is larger.

In figure: 1, guide; 2, latch; 3, position-limit mechanism; 4, adjusting nut; 5, stage clip; 6, guide pad; 7, bottom bracket; 9, guide pin bushing; 10, position-limited wheel; 11, wire rope; 12, guide rail; 13, strut rail; 14, stop; 15, safety guard; 16, truss; 17, cord; 18, transmission component; 19, door lifter.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described:
As Figure 1-4, the present invention is mainly comprised of guide 1, latch 2, position-limit mechanism 3, adjusting nut 4, stage clip 5, guide pad 6, bottom bracket 7, wire rope 11, guide rail 12, strut rail 13 and stop 14.Wire rope 11 lower ends are fixedly connected on folded door bottom bracket 7 Shang， upper ends and are connected with door lifter 19.The one or both ends of bottom bracket 7 (being left side or right side or the left and right sides in Fig. 1) are provided with safety guard 15, safety guard 15 comprises guide 1, latch 2, guide pad 6, guide 1 and guide pad 6 are fixedly mounted on bottom bracket 7, described latch 2 and guide 1 have two, before, rear flat raft is arranged, a left side for two latches 2, right two ends are placed through respectively in corresponding guide 1 and guide pad 6, the guide rail 12 of the outer end of described latch 2 on door opening column, corresponding to this latch 2, on guide rail 12, be furnished with the strut rail 13 matching in some ends with it, and be provided with in guide rail 12 bottoms the stop 14 that match in end with it.Strut rail 13 also can change jack, pit or projection into.Wire rope 11 passes between two latches 2, on two latches 2, position-limit mechanism 3 is installed, and described position-limit mechanism 3 one sides are located by wire rope 11, and opposite side withstands on stage clip 5 one end, and the other end of stage clip 5 withstands on guide pad 6.
Position-limit mechanism 3 of the present invention can be an overall structure, also can be combining structure as shown in Figure 2, while adopting combining structure, include between 9, two guide pin bushings 9 of two guide pin bushings that are arranged on two latches 2 position-limited wheel 10 is installed, position-limited wheel 10 touches with described wire rope 11.
Screw mandrel is arranged in the stage casing of latch 2 of the present invention, and adjusting nut 4 is arranged on this screw mandrel, and stage clip 5 is sleeved on latch 2 and between adjusting nut 4 and guide pad 6.
Once wire rope 11 is because of wearing and tearing or aging fracture, latch 2 can penetrate in the strut rail 13 on guide rail 12 because of the effect of stage clip 5, and door cognition is stuck on the strut rail 13 on guide rail 12 at dropping process, guarantees safety.
As can be seen from Figure 4, at blast, very gate body is closed in the situation that, the cord on door body, because of blast flexural deformation, can drive bottom bracket 7 along guide rail 12 upwards slippages, Yin Men in off position, wire rope 11 is lax, and owing to losing after the pulling force of wire rope 11, position-limit mechanism 3 loses the constraint to latch 2, due to stage clip 5 effects, latch 2 can penetrate guide rail 12, props up the bottom of the stop 14 of guide rail 12 bottoms, the upper cunning of folded every body in prevention.
Other the undeclared part the present invention relates to is same as the prior art.
