Abstract
The utility model discloses a connecting structure for an air pipe for feeding fresh air in a crown block cab, which consists of a main rigid air pipe, sealing rubber, a connecting branch nozzle and a connecting bolt, wherein the bottom of the main rigid air pipe is provided with a notch; the notch at the bottom of the main rigid air pipe (1) is connected with the connecting branch nozzle (3) of an air feeding branch pipe (5); the sealing rubber (2) is arranged outside the connecting branch nozzle (3); the lower end of the sealing rubber (2) is connected with the notch at the bottom of the main rigid air pipe (1) through a bolt (4); the size of the notch at the bottom of the main rigid air pipe (1) is the width of the connecting branch nozzle (3) plus 80mm; and the single side of the sealing rubber (2) is provided with a groove. The connecting branch nozzle can penetrate through the notch at the bottom provided with the sealing rubber, and is inserted into the main rigid air pipe, and is connected with the crown block cab through the air feeding branch pipe. A fan feeds air into the main rigid air pipe to keep the inside of the main rigid air pipe to be always filled by positive-pressure fresh air; therefore, the purpose of feeding fresh air into the cab can be realized.
Description
Technical field
The utility model relates to a kind of overhead traveling crane and needs in the moving process to get the structure that new wind is sent into the overhead traveling crane operator's compartment in industrial premises outside factory building, belongs to industrial overhead traveling crane aeration technology field.
Background technology
In existing magnesium eletrolysis workshop, the installation and maintenance main equipment all needs to use overhead traveling crane, and in the magnesium eletrolysis workshop toxic and harmful more (as chlorine), make overhead traveling crane navigating mate required new wind in operator's compartment directly in the workshop, to obtain by natural ventilation system.The magnesium eletrolysis shop characteristic has: 1. overhead traveling crane is in the mobile working state at any time in the factory building, promptly has the displacement of overhead traveling crane direction along ng a path in the workshop; 2. there is slight double swerve (generally being not more than 30mm) in overhead traveling crane in operational process; 3. magnesium eletrolysis workshop factory building is long usually.These 3 features just make general air-supply arrangement be difficult to satisfy existing magnesium eletrolysis workshop overhead traveling crane operator's compartment and send new wind requirement.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of overhead traveling crane operator's compartment simple in structure to send new wind airduct connection structure, enter the overhead traveling crane operator's compartment and be detrimental to health etc. not enough to overcome toxic and harmful in the magnesium eletrolysis workshop that prior art exists.
The utility model is to constitute like this: the notch of rigidity air main bottom with prop up mouth being connected of blowpipe and connect, in the outside that connects a mouth caulking gum is arranged, the notch of the lower end of caulking gum bottom the rigidity air main is connected.
The lower end of caulking gum is connected by the notch of bolt with rigidity air main bottom.
Rigidity air main bottom plate rabbet is of a size of the width that connects a mouth and adds 80mm.This structure can satisfy connect a mouth with overhead traveling crane double swerve 30mm with interior displacement request.
The monolateral groove of establishing of caulking gum.Groove angle is 70～80 °.This structure makes caulking gum after fixing by tie bolt on the rigidity air main, and the overlap joint angle is about 10～20 °.Connect a mouth simultaneously and pass caulking gum and enter in the rigidity air main length and should not be lower than caulking gum and enter rigidity air main inner height, thereby guarantee that as far as possible new wind is sent into the overhead traveling crane operator's compartment along connecting a mouth in the rigidity air main.
Outdoor new wind enters the rigidity air main by blower fan makes its inside be full of the new wind of malleation all the time, and a connection mouth is got new wind from air main and is conveyed into the overhead traveling crane operator's compartment by blowpipe, thereby realizes that operator's compartment send the purpose of new wind.
Connecting a mouth can move on rigidity air main axial direction, meets the overhead traveling crane feature that needs move on rigidity air main axial direction.
Caulking gum is subjected to the new wind effect of malleation in the rigidity air main, makes bottom plate rabbet be in relative sealing state all the time.
The bottom plate rabbet of caulking gum and rigidity air main is convenient to install and dismounting by bolted connection.

The specific embodiment
Embodiment of the present utility model: the notch of rigidity air main 1 bottom with prop up mouth 3 being connected of blowpipe 5 and connect, in the outside that connects a mouth 3 caulking gum 2 is arranged, the lower end of caulking gum 2 is connected with the notch of rigidity air main 1 bottom.
The lower end of caulking gum 2 is connected with the notch of rigidity air main 1 bottom by bolt 4.
Rigidity air main 1 bottom plate rabbet is of a size of the width that connects a mouth 3 and adds 80mm.
The caulking gum 2 monolateral grooves of establishing.Groove angle is taken as 75 °.
A side factory building pillar that is higher than the about 2.1m of overhead traveling crane tread in the magnesium eletrolysis workshop is the rigidity air main fixedly, the caulking gum side is arranged down, after with tie bolt caulking gum and rigidity air main bottom plate rabbet being fixed, to connect mouth and inject in the caulking gum, will connect again and prop up a mouth and be connected with branch vent and tap into the overhead traveling crane operator's compartment.The rigidity air main is connected by airduct with outdoor fan.After installing, this structure needs between a mouth and caulking gum, to smear just removable overhead traveling crane of enough lubricating oils.
Claims (4)
1. an overhead traveling crane operator's compartment send new wind airduct connection structure, it is characterized in that: the notch of rigidity air main (1) bottom with prop up mouth (3) connection being connected of blowpipe (5), in the outside that connects a mouth (3) caulking gum (2) is arranged, the lower end of caulking gum (2) is connected with the notch of rigidity air main (1) bottom.
