Abstract
The utility model relates to cold storage door, particularly a pneumatic cold storage door. The utility model needs to solve the problems of manpower wasting by manual doors, complicated program on electric doors, and high failure rate existing in the background art, and the problems that the performance and the service life of the background art are influenced by low temperature and moisture, and the mechanical part of the background art is easy to cause lube oil contamination and mechanical failures. In order to solve the technical problems, the utility model has the technical scheme that a lifting lug is connected with a piston rod in an air cylinder, the piston rod is connected with an electromagnetic valve and an air pipe, and the air pipe is connected with an air source through a three-position five-way electromagnetic valve. The utility model can be applied to various cold storage doors, and has the advantages of low noise, reliable performance, long service life and high safety. The utility model has the obvious advantage of convenient on-off and labor saving when manually operated in a power-off state.
Description
Technical field: the utility model relates to a kind of cold-storage door, particularly a kind of pneumatic cold-storage door.
Background technology: the existing cold-storage door of existing cold-storage door divides manual cold-storage door and electronic cold-storage door two big classes, and electronic cold-storage door is divided into two kinds at chain door and tooth bar door.Manually operated door manpower switch, waste of manpower.Electric door is controlled with PLC, program complexity, fault rate height; Temperature is low in the freezer, and there was dampness in the air, and is bigger to the infringement of electric elements such as remote controller pullswitch, influences its performance and application life; In addition, the three-phase voltage-stabilizing protection device of electric door is subjected to current affects big, burns easily.The electric door mechanical part need be used oil lubrication, and sealing is not with great difficulty leaked, and pollutes, and is especially serious at frozen products chamber; The long-time tension of chain is broken or loosening easily, with components hit on every side, causes damage, and the tooth bar transmission is worn and torn for a long time, and the gap increases, and noise is big, even can cause storehouse door dislocation.
Summary of the invention: the purpose of this utility model is exactly the technical scheme that proposes a kind of pneumatic cold-storage door, solving the manually operated door waste of manpower that background technology exists, electric door program complexity, fault rate height, performance and life-span are subjected to that low temperature and moisture influences, mechanical part easily causes lubricant pollution and mechanical breakdown.Solving this technical problem the technical scheme that is adopted is: a kind of pneumatic cold-storage door, being provided with guide wheel on the guide rail also can be along the hanger of guide rail slip, hanger connects the storehouse door, it is characterized in that hanger connects the piston rod in the cylinder, piston rod connects electromagnetic valve and tracheae, and tracheae connects source of the gas by the 3 position-5 way electromagnetic valve.Wherein, between hanger and the piston rod electromagnet is set.
Can realize according to technique scheme, open the door: electromagnetic valve 8 energisings, be in closed condition, electromagnet 4 energising adhesives, 6 energisings of 3 position-5 way electromagnetic valve, the P mouth is connected with the A mouth, B mouth and exhaust opening O
2Connect; Source of the gas 5 is to cylinder 9 left chamber inflations, and when air pressure reached certain value, piston rod 10 promoted whole storehouse door and moves right, and Ku Men opens, and the air in cylinder 9 right chambeies is then by exhaust opening O
2Discharge.Close the door: electromagnetic valve 8 energisings, be in closed condition, electromagnet 4 energising adhesives, 6 energisings of 3 position-5 way electromagnetic valve, the P mouth is connected with the B mouth, A mouth and exhaust opening O
1Connect; Source of the gas 5 is to cylinder 9 right chamber inflations, and when air pressure reached certain value, piston rod 10 promoted whole storehouse door and is moved to the left, and Ku Men closes, and the air in cylinder 9 left chambeies is then by exhaust opening O
1Discharge.Manually: electromagnetic valve 8 outages, be in normally open, electromagnet disconnects, and piston rod 10 and storehouse gantry crane ear 3 leave, and do not need to drive piston rod during hand switch and move, and move light.As above, the utility model has been cancelled mechanical driving part, makes that noise is low, the dependable performance life-span is long, safety good.Cut off the power supply when manual, switch is light laborsaving.
Description of drawings: Fig. 1 is the utility model structural representation.
The specific embodiment: with reference to figure 1, a kind of pneumatic cold-storage door, being provided with guide wheel 2 on the guide rail 1 also can be along the hanger 3 of guide rail slip, hanger 3 connects storehouse door 11, hanger 3 connects cylinder 9 inner piston rods 10, piston rod 10 connects electromagnetic valve 8 and tracheae 7, and tracheae 7 connects source of the gas 5 by 3 position-5 way electromagnetic valve 6, between hanger 3 and the piston rod 10 electromagnet 4 is set.
Claims (2)
1, a kind of pneumatic cold-storage door, being provided with guide wheel (2) on the guide rail (1) also can be along the hanger (3) of guide rail slip, hanger (3) connects storehouse door (11), it is characterized in that hanger (3) connects the piston rod (10) in the cylinder (9), piston rod (10) connects electromagnetic valve (8) and tracheae (7), and tracheae (7) connects source of the gas (5) by 3 position-5 way electromagnetic valve (6).
2,, it is characterized in that between hanger (3) and the piston rod (10) electromagnet (4) being set according to the described a kind of pneumatic cold-storage door of claim 1.
