Abstract
The utility model discloses a labor saving kiln door. The utility model has a structure that a pair of suspension arms 3 are installed in different directions on the upper edge of the kiln door 4 on an inclined kiln hood 1, and one end of each suspension arm 3 is provided with a balancing weight 2. The utility model has the advantages of convenient operation, less labor used for opening and closing the kiln door, and long service life of the kiln door.
Description
The utility model relates to a kind of wicket of mechanical vertical kiln, particularly a kind of laborsaving wicket that can reduce wicket open and close pulling force.
The wicket of existing mechanical shaft kiln is installed in the bottom of taper kiln hood, is bound up on the kiln hood with two hinges.Because the kiln hood upper end diameter is little, lower end diameter is big, thereby actuating doors and plumb line are angled, promptly forming " door tilts ", so open and close actuating doors, is that the side applies pulling force obliquely, the weight of every fan door is the 55-65 kilogram, and the switching manipulation door is required great effort very much.Cement mechanized shaft kiln firing operational procedure regulation, must " firing of closing the door ", but also the necessary state of often observing material surface in the kiln, so just must frequently open and close actuating doors by operating personnel, because open and close actuating doors requires great effort very much, many firing workmans firing of " opening the door ", thereby spray kiln accident causes the phenomenon of operator's injures and deaths to happen occasionally, perhaps after effort opening operation door operation finishes, at closing time, often close to a certain degree and just loose one's grip, actuating doors then falls to closing by deadweight, and this moment, door produced bump greatly with " doorframe ", great noise not only takes place, also therefore shorten the service life of wicket widely, both caused economic loss, also damaged people's health.Though someone improves the global shape of actuating doors, one " doorframe " welded in employing on the inclined plane of taper kiln hood, the kiln hood surface is stretched out in this doorframe upper end, therefore its Men Zeke vertically installs formation " upright door ", though this method has been used hundreds of kilograms steel plate more, solved the problem of switching manipulation door effort also, however overhanging " doorframe " in its upper end, often impact operations person's head, thereby many users all is reluctant to use this kind " upright door ".
The purpose of this utility model is to want to overcome above-mentioned the deficiencies in the prior art, and a kind of improved wicket is provided, and this wicket is easy to operate, and switch is firmly little, long service life.
For achieving the above object, the technical solution adopted in the utility model is: the utility model comprises two fan wickets, every fan wicket is installed on the kiln hood by hinge, and its design feature is that one end of cantilever is provided with balancing weight at a pair of cantilever of the incorgruous installation of the upper limb of every fan wicket.
The utility model is owing to be provided with cantilever and counterweight at every upper limb of fanning door, when opening at closing time, by cantilever the moment of counterweight to hinge is added on this door, thereby offset the moment of the component of gravity on the switch direction of door to hinge, make door be easy to open and close, also avoided the bump of door, prolonged the service life of door with kiln hood.
Fig. 1 is the structural representation of the utility model embodiment
Below in conjunction with drawings and Examples the utility model is done further detailed description
As seen from Figure 1, two fan wickets 4 are installed on the kiln hood 1 by hinge 7, a pair of cantilever 3 are housed in that the upper limb of two fan wickets 4 is incorgruous, and an end of cantilever 3 is provided with balancing weight 2, be provided with locking plate 5 on wicket 4, the moment that balancing weight 2 arrives hinge 7 is slightly less than the moment that wicket 4 arrives this hinge.The right side of Fig. 1 is two fan wicket closed conditions, and the left side is the fan open mode in the two fan wickets.
Claims (1)
1, a kind of laborsaving wicket contains two fan wickets (4), and wicket (4) is installed on the kiln hood (1) by hinge (7), it is characterized in that: at the incorgruous a pair of cantilever (3) of adorning of the upper limb of every fan wicket (4), an end of cantilever (3) is provided with balancing weight (2).
