Abstract
A tool for opening and closing a drying tower of an air compressor is characterized in that the tool comprises a base, a pressure plate, a screw rod and a tightening nut, wherein the lower end of the screw rod is connected with the base, and the upper end thereof passes through the pressure plate and is connected with the tightening nut; and a circular hole which can be sleeved on a locknut at the top of the drying tower is arranged at the center of the pressure plate. The utility model adopts the principle of the nut and the screw rod, the pressure plate is driven by tightening the tightening nut on the screw rod to compress a spring in the tower, when the spring is compressed to a certain extent, the locknut at the top of the drying tower is opened by a special wrench, then the tightening nut on the screw rod is reversely and slowly rotated till the spring in the tower restores to the natural stretching state from the compressed state, and a sealing device at the top of the drying tower can be safely disassembled, and finally the drying tower is disassembled from the tool and placed on a special worktable to change the desiccant. The utility model solves the problem that the drying tower cannot be opened and closed without the special tool, and is successfully applied to CRH5 motor train unit overhaul.
Description
Technical field
When relating to a kind of air compressor machine repair and maintenance, the utility model changes drying tower internal desiccant frock.
Background technology
CRH5 EMUs move 1,200,000 kilometers needs and carry out three grades of maintenance, must change the drier in the drying tower when air compressor machine is overhauled, and do not have special-purpose frock can't open the replacing that drying tower is finished drier.
The utility model content
The utility model purpose provides that a cover is opened and the frock of sealing CRH5 EMUs air compressor machine drying tower, use this cover frock can guarantee to change unlatching drying tower easy, safe before the drier and changed drier after the sealing of drying tower.
For achieving the above object, the utility model provides a kind of air compressor machine drying tower to open, seal frock, it is characterized in that: comprise base, pressing plate, screw mandrel, fastening nut, the screw mandrel lower end connects base, the upper end is passed pressing plate and is connected fastening nut, and the pressing plate center has the circular hole that can be enclosed within on the locking nut of drying tower top.
Good effect of the present utility model is: the top seal device of drying tower is a tower inner spring roof pressure structure, and the locking nut on it is a special nut, this frock adopts nut screw mandrel principle, drive pressing plate compression tower inner spring by the fastening nut of screwing on the screw mandrel, when the compression spring to a certain degree the time, use special spanner to open drying tower top locking nut, fastening nut on the oppositely slow then rotary screw, return to the nature stretched condition until the tower inner spring from compressive state, can disassemble by the safe sealing device with the drying tower top this moment, drying tower is unloaded from frock, be placed on and change drier on the dedicated.Sealing drying tower requirement after having satisfied safety, easy unlatching drying tower and having changed drier, to have solved do not have special tooling can't finish the problem of opening and sealing drying tower, and successful Application in the CRH5 EMUs maintenance.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, air compressor machine drying tower 1 is placed on CHR5 EMUs air compressor machine drying tower to be opened, on the base 2 of sealing frock, pressing plate 5 centers have the circular hole that can be enclosed within on the locking nut of drying tower top, the fastening nut 4 of screwing on the screw mandrel 3 drives pressing plate 5 compression tower inner springs, when the compression spring to a certain degree the time, use has the ratchet spanner of special driving end and opens drying tower top locking nut, fastening nut 4 on the oppositely slow then rotary screw, return to the nature stretched condition until the tower inner spring from compressive state, can disassemble by the safe sealing device with the drying tower top this moment, finishes the operation of opening drying tower.
Drier is placed on drying tower 1 on the frock after changing and finishing.Drive pressing plates 5 compression tower inner springs by the fastening nut 4 of screwing on the screw mandrel, when the compression spring to a certain degree the time, use the ratchet spanner that has special driving end to tighten drying tower top locking nut, finish the sealing that drying tower is changed drier.
