Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly can prevents from gate from happening suddenly falling and can the application plant gate anti-drop device of available protecting lower chord.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of application plant gate anti-drop device, comprise column, slideway and lower chord, lower chord, slideway and column from left to right direction distribute successively, and lower chord can move up and down along the bearing of trend of slideway, its innovative point is: described lower chord be also provided with lifting wheel, anti-fall plate, spring and connect push rod, slideway is also provided with anti-falling rods;
The both sides of described lifting wheel are arranged on lifting wheel fixed head respectively, the side of lifting wheel fixed head is hinged by connection bearing pin and lower chord, opposite side is connected with anti-fall plate by connecting push rod, lifting wheel fixed head can swing up and down along the pin joint of lifting wheel fixed head and lower chord, described lifting wheel fixed head be connected push rod, connect to be hinged between push rod and anti-fall plate and form;
Described anti-fall slab integral is S-shaped, the head of this anti-fall plate is hook-shaped, and cooperatively interact with the anti-falling rods on slideway, the tail end of anti-fall plate is connected with the upper end of lower chord by spring, the lower end of described anti-fall plate is arranged on lower chord by fulcrum fixed head, described fulcrum fixed head one has two, be positioned at the both sides of anti-fall plate, and fulcrum fixed head passes through connection bearing pin and anti-fall plate is hinged, described anti-fall plate can promote swing along the pin joint of anti-fall plate and fulcrum fixed head by connecting push rod.
Further, described lifting wheel fixed head is positioned at the top of the pin joint connecting push rod and anti-fall plate all the time with the pin joint being connected push rod, and described fulcrum fixed head and the pin joint between anti-fall plate are in the below being connected the pin joint between push rod and anti-fall plate.
The utility model has the advantage of: anti-drop device of the present utility model; spring buffer power and lever principle is utilized to combine to prevent the burst at gate to fall the generation of phenomenon; utilize anti-fall plate to catch on anti-falling rods in advance and play the effect preventing gate from falling; successfully evade on incident impact force direct effect and lower chord simultaneously; available protecting lower chord; avoid lower chord to occur the phenomenon of being out of shape because of the impact of incident impact force, extend its application life.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of application plant gate anti-drop device of the present utility model.
Fig. 2 is the A-A view of Fig. 1.
Detailed description of the invention
Schematic diagram is as shown in Figure 1 and Figure 2 known, and application plant gate anti-drop device of the present utility model comprises column 3, slideway 2, lower chord 1, lifting wheel 5, anti-fall plate 10, spring 6 and connects push rod 7.
Lower chord 1, slideway 2 and column 3 distribute in direction from left to right successively, slideway 2 is arranged on the side of column 3, lower chord 1 can move up and down along the bearing of trend of slideway 2, lifting wheel 5, anti-fall plate 10, spring 6 and connection push rod 7 are installed on lower chord 1, anti-falling rods 10 has several, be evenly distributed on slideway 2, and mutual vertical distribution between anti-falling rods 10 and slideway 2.
There is in the both sides of lifting wheel 5 a lifting wheel fixed head 4 respectively, the both sides of lifting wheel 5 are arranged on lifting wheel fixed head 4 respectively, the side of lifting wheel fixed head 4 is hinged by connecting between bearing pin 11 and lower chord 1, the opposite side of lifting wheel fixed head 4 is connected with anti-fall plate 8 by connecting push rod 7, lifting wheel fixed head 4 can swing up and down along the pin joint of lifting wheel fixed head 4 with lower chord 1, lifting wheel fixed head 4 be connected push rod 7, be hinged between connection push rod 7 and anti-fall plate 8 and form, and lifting wheel fixed head 4 and the pin joint being connected push rod 7 are positioned at the top of the pin joint connecting push rod 7 and anti-fall plate 8 all the time.
Anti-fall plate 8 is overall S-shaped, the head of this anti-fall plate 8 is hook-shaped, and be used in conjunction with each other with the anti-falling rods 10 be arranged on slideway 2, the tail end of anti-fall plate 8 is connected by the upper end of spring 6 with lower chord 1, the lower end of anti-fall plate 8 is arranged on lower chord 1 by fulcrum fixed head 9, fulcrum fixed head 9 one has two, lay respectively at the both sides of anti-fall plate 8, and fulcrum fixed head 9 is hinged by connecting between bearing pin 11 and anti-fall plate 8, anti-fall plate 8 can be promoted to swing along the pin joint between anti-fall plate 8 and fulcrum fixed head 9 by connection push rod 7.
Pin joint between fulcrum fixed head 9 with anti-fall plate 8 is in the below being connected the pin joint between push rod 7 and anti-fall plate 8.
When gate due to hoist engine wire rope disconnected fall or loosen etc. reason and cause gate occur burst fall phenomenon time, the phenomenon of lopsidedness can be there is because of the impact of self gravitation in lifting wheel fixed head 4 due to the disappearance of the lifting force of lifting wheel 5, simultaneously lifting wheel fixed head 4 can promote to connect push rod 7 and moves, thus drive the upper end of anti-fall plate 8 to swing to anti-falling rods 10 direction, and utilize the upper end of anti-fall plate 8 to catch on anti-falling rods 10, thus lower chord 1 can be prevented descending, and can protect lower chord 1, avoid causing the bottom of lower chord 1 to produce distortion because of the impact force of burst, affect it normally to use, finally can prevent the gate be connected with lower chord 1 from falling.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
