Description
Technical field
The present invention relates to a kind of lifting means, especially a kind of safety guard that is used for the material lifting means.
Background technology
Existing material lifting means is gig for example, and its rope broken protector reflection is slow, generally needs 1～3 second time just can react, and can not fast hand basket be pinned behind the disconnected rope, and therefore hand basket tenesmus accident often takes place.And the very easy generation of overloading free warning facility, accident.And gig overweight be the major reason that causes the lifting means accident, it is common phenomena that the material lifting means is exceeded the bounds, the lifting means back boxes and baskets of exceeding the bounds tilt, and cause goods to fall from the high-altitude, easily ruin thing and hurt sb.'s feelings.In addition, the hand basket pulley system adopts four straps to connect, and hand basket rocks greatly during operation, and is not steady.
Summary of the invention
The technical problem to be solved in the present invention is; a kind of lifting means rapid protecting device is provided; use this device; can react fast in the moment that the lifting rope fracture takes place, the thing that the hand basket tenesmus that effectively prevents to cause because of the lifting rope fracture causes is ruined the people and is hindered accident and take place and send warning when lifting means overloads.
Technical solution of the present invention is; described lifting means rapid protecting device; referring to Fig. 1～4, there are pulley 2, second splint 3, wheel shaft 4, two guide rods 5, limit for tonnage stage clip 6, overload warning device 7, two guide rod seats 8, stay cord 9, fixed support 10, extension spring 11, removable pin 12, pulley 13, guide rail 15, chute 16, door type to hang carriage 17, hand basket crossbeam 18 and removable pin slide 19.Wherein said pulley 2 is connected between the two clamping plates 3 by wheel shaft 4 and can rotates on wheel shaft 4, and wheel shaft 4 is by clamping plate 3 supportings, and clamping plate 3 are connected with two guide rods 5 can slide up and down guide rod 5 in guide rod seat 8.Two guide rod seats 8 connect fixed support 10, and fixed support 10 connects hand basket crossbeam 18, limit between guide rod 5 and the fixed support 10 to carry stage clip 6 and overload warning device 7.Described fixed support 10 belows connect stay cord 9, and above-mentioned pulley 13 is installed on the hand basket crossbeam 18, and stay cord 9 is hung carriage 17 by the door type that pulley 13 connects hand basket crossbeam 18 two ends respectively.Connecting removable pin 12 respectively on the door type extension carriage 17 can slide removable pin 12 in the removable pin slide 19 on the hand basket crossbeam 18.Described extension spring 11 is connected door type and hangs on carriage 17 and the hand basket crossbeam 18.Described chute 16 is installed on the hand basket crossbeam 18 and can slides along above-mentioned guide rail 15.The present invention installs two guide rails 15 in column 20 both sides; hand basket is moved up and down along guide rail 15; the accident that the unlikely generation hand basket of lifting means is exceeded the bounds; simultaneously also limit two columns and open bending outward; play the effect of a midship mounting; so as to the resistance to overturning of raising lifting means, thereby lifting means is played the actv. protective effect.
Principle of work of the present invention is: described lifting means rapid protecting device is installed in gig hand basket top; the steel rope 1 of gig hangs hand basket by pulley 2; when the steel rope 1 of lifting means elongates or shortens on one side; the track of the guide rail 15 that the chute 16 that the rotation by pulley 2 relies on hand basket to be installed in the hand basket both sides is installed on the column 20 puts down or rises, and goods or personnel just can transport eminence to or transport lower to from eminence from lower by lifting means.
When lifting means normally moves; the steel rope 1 of lifting means with a power that makes progress with pulley 2; clamping plate 3; wheel shaft 4; guide rod 5 up draws; two limit for tonnage stage clips 6 that install guide rod 5 lower ends are compressed; two stay cords 9 of guide rod 5 lower end bonded assemblys are upwards drawn; two door types are hung carriage 17; removable pin 12 is drawn to the position of withdrawal by pulley 13 by stay cord 9; the extension spring 11 that is connected between door type extension carriage 17 and the crossbeam 18 is elongated; the chute 16 that is installed in the lifting means both sides is buckled on the guide rail of installing on the column 20 15; like this, whole lifting means rapid protecting device is just in running order.
When lifting means overloaded, two limit for tonnage stage clips 6 were compressed and surpass when being scheduled to limit for tonnage, and overload warning device 7 is reported to the police; When the steel rope 1 of lifting means is rubbed or the time marquis of the rope-broken accident that meets accident; owing to having had pulling force traction that steel rope 1 makes progress to be subjected to two limit for tonnage stage clips, 6 downward screen resiliences suddenly, pulley 2, clamping plate 3, wheel shaft 4, guide rod 5 do not move downward; at this moment; stay cord 9 loosens; door type is hung carriage 17, removable pin 12 and is pulled to removable pin 12 by extension spring 11 and stretch out the upright about 100 millimeters position of crossbeam 14 of leaning on; hand basket is hung on the column 20 on both sides can not fall down, thus the safety of protection personnel and goods.
Be installed in the gig both sides column 20 guide rail 15 and be installed in the chute 16 that can slide along guide rail 15 the lifting means both sides and when the lifting means up-and-down movement, play the guiding role, make hand basket rise and descend along guide rail 15, hand basket tilts the phenomenon that goods and personal height fall because of lifting means is exceeded the bounds afterwards to be unlikely to generation.
The invention has the beneficial effects as follows: use described lifting means rapid protecting device, can when overloading, send by lifting means warning, and can react fast in the moment that the lifting rope fracture takes place, the thing that the hand basket tenesmus that effectively prevents to cause because of the lifting rope fracture causes is ruined the people and is hindered accident and take place; Two guide rails 15 installed in gig column both sides and the chute 16 that can slide along guide rail 15 make lifting means about guide rod, make lifting means be unlikely to take place the phenomenon that lifting means is exceeded the bounds, thereby lifting means or elevator are played the actv. protective effect.
