Description
Technical field
The utility model relates to a kind of coupling, is specifically related to a kind of Hooks coupling universal coupling of realizing the synchronous operation of special-shaped longspan rolling shutter door.
Background technique
Around the Hui Malang, hall of building in business type, staircase hole etc., folded lifting type fire-proof rolling shutter door need to be installed and carry out fireproof partition.The working principle of existing folded lifting type fire-proof rolling shutter door is, first use EXPANSION ANCHOR BOLTS that fixing frame is fixed to ceiling, in the position apart from ceiling certain distance, transmission roll shaft is installed, one end of wire rope is connected on transmission roll shaft, and the other end of wire rope is connected with the metal draw ring that is located at fire prevention door curtain made of cloth body through the static pulley being welded on fixing frame; In the bottom of fire resisting shutter, be provided with collet simultaneously, can slide along the guide rail in column in collet two ends, adopt Electric Machine Control transmission roll shaft forward, rotate backward to promote and the wire rope that declines is controlled the folding of fire prevention cord and stretches, thereby realize the lifting of whole fire resistance rolling shutter door and then realize the effect of fireproof partition.When running into longspan even when super-span Hui Ma corridor, special-shaped hall or special-shaped hole, if span is 100 meters～300 meter Hui Ma corridors, special-shaped hall or special-shaped hole, when folded lifting type fire-proof rolling shutter door is installed, in order to prevent that the large appearance of rolling shutter door span middle part from, because of the sagging frpf effect that do not have of conducting oneself with dignity, being generally every 10 meters of needs, one group of column to be installed along straightway.Take column as partition, fire resistance rolling shutter door is divided into a plurality of parts, and on each column, the guide rail moving for collet is installed.In special-shaped position, as each corner, also need to arrange one group of column and be used for mounting guide rail.
There is following shortcoming in above prior art:
1, affect speed of application, increase cost.Along straightway every 10 meters and each corner, all need to arrange one group of column and be used for fixing guide rail, so not only increased the material cost of column, and it is loaded down with trivial details to construct, increase the workload of construction, delayed construction speed, increased construction intensity, cost of labor is also corresponding to be improved greatly, has greatly increased overall cost.
2, operation synchronism is difficult to control.For the fire resistance rolling shutter door of super-span, super many abnormity, adopt prior art to be used for fixing guide rail owing to having increased many columns, therefore need to increase the motor of respective numbers.When having fire-fighting actuating signal or stop signal to send to motor, because number of motors is numerous, because there is a little difference in reaction time of each motor start and stop, be difficult to control the operation synchronism of each motor, thereby cause roller shutter everywhere to stretch or be folding asynchronous, be difficult to the requirement that reaches fire-fighting test and check and accept.
3, space availability ratio is not high, affects attractive in appearance.Owing to having increased many columns, be used for fixing guide rail, take a large amount of spaces.And for the commercial building having higher requirements, for fire-fighting requires that many columns are set in addition, also affect attractive in appearance.
Model utility content
Technical problem to be solved in the utility model is, a kind of Hooks coupling universal coupling of realizing the synchronous operation of special-shaped longspan rolling shutter door is provided, and this Hooks coupling universal coupling can reduce construction amount, reduce costs and easily realize the synchronism that rolling shutter door rises and declines when longspan rolling shutter door is installed.
Technical solution of the present utility model is, a kind of Hooks coupling universal coupling with the realization abnormity longspan rolling shutter door synchronous operation of following structure is provided, and comprising:
The first adpting flange that one end is connected with the first roll shaft, described the first roll shaft is connected with rolling shutter door;
The first flange jaw, the second flange jaw, the first cross axle, described the first flange jaw is connected with the other end of the first adpting flange, and the first flange jaw is crisscross arranged and is connected through the first cross axle with the second flange jaw;
Transmission shaft ，Qi one end is connected with the second flange jaw;
Three-flange jaw, is connected with the other end of transmission shaft;
The 4th flange jaw, the second cross axle, described three-flange jaw is crisscross arranged and is connected through the second cross axle with the 4th flange jaw;
The second adpting flange that one end is connected with the second roll shaft, the other end of the second adpting flange is connected with the 4th flange jaw.
Compared with prior art, the Hooks coupling universal coupling of the special-shaped longspan rolling shutter door of realization of the present utility model synchronous operation, has the following advantages.In the middle of being located at by Hooks coupling universal coupling of the present utility model, the first roll shaft and the second roll shaft that are positioned at both sides are coupled together, by the connection of a plurality of Hooks coupling universal couplings, realize the installation of longspan rolling shutter door, centre does not need to arrange a lot of root posts, not only reduced the material cost of column, also reduce the workload of construction column and reduce construction cost, and because whole longspan rolling shutter door all links by Hooks coupling universal coupling of the present utility model, can reduce the quantity of motor and the motor selecting to match.Because number of motors is few, easily realize the synchronism that rolling shutter door rises and declines.In addition due to the first flange jaw and the second flange jaw through the first cross axle be connected, three-flange jaw is connected through the second cross axle with the 4th flange jaw, between described the first flange jaw and the second flange jaw, all can relatively have rotation angle between three-flange jaw and the 4th flange jaw, make Hooks coupling universal coupling of the present utility model when connecting, not be subject to the impact of abnormity and corner.
