Abstract
A zipper type brake cylinder corrugated protective sleeve relates to a motor train unit brake system, solves the problem that the corrugated protective sleeve can be replaced only by detaching a clamp from a bogie in the maintenance process of the existing corrugated protective sleeve, and has high replacement difficulty, and comprises a dustproof cover body, a waterproof zipper and a suture line; the waterproof zipper is fixed on the dustproof cover body through sewing threads; adhesive is evenly smeared on the whole contact surface in the two ends of the waterproof zipper and the dustproof cover body, the suture line position along the extension direction of the suture line and the surface of the exposed suture line on the outer surface of the dustproof cover body, and the closed tail end of the waterproof zipper is arranged at the large end of the dustproof cover body. After the adhesive is solidified, stainless steel hose clamps are arranged at two ends of the dustproof cover body. The novel corrugated protective sleeve is convenient to replace and ensures the sealing performance of the corrugated protective sleeve; the fatigue performance requirement and reliability of the zipper type corrugated protective sleeve are ensured; the low temperature resistance and the high temperature resistance of the zipper type corrugated protective sleeve are ensured, and the sewing quality between the corrugated protective sleeve rubber and the zipper is ensured.
Description
Technical Field
The utility model relates to a EMUs braking system, concretely relates to zip fastener formula checking cylinder ripple protective sheath. The method is applied to the operation and maintenance of CRH series motor train units.
Background
A brake cylinder of a brake clamp of a motor train unit belongs to a mechanical moving part, and in order to ensure free movement of a piston in the cylinder and prevent external water stains and foreign particles from entering to cause clamping stagnation, an integrated corrugated protective sleeve for sealing is installed outside a brake cylinder body.
At present, the brake cylinder corrugated protective sleeve is influenced by the use environment in the vehicle application, and the brake cylinder corrugated protective sleeve is damaged by being hit by foreign matters. When the motor car is maintained and overhauled, the clamp brake cylinder is in a hoisting and fixing state on the bogie, and the corrugated protective sleeve can be replaced only by detaching the clamp from the bogie, so that the field replacement difficulty of the motor car is huge after the corrugated protective sleeve is damaged.
The brake caliper and the brake cylinder are mounted on the motor train unit, so that the corrugated protective sleeve cannot be replaced independently without dismounting the brake caliper and the brake cylinder.
In order to solve the problem that the field replacement difficulty of the motor train unit is high after the corrugated protection sleeve of the brake cylinder of the motor train unit is damaged, a new scheme for rapidly replacing the corrugated protection sleeve of the brake cylinder under the condition of not dismantling a clamp is researched.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve current ripple protective sheath maintenance process, need demolish clamp from the bogie, just can change the ripple protective sheath, have the problem that the change degree of difficulty is big, provide a zip fastener formula checking cylinder ripple protective sheath.
A zipper type brake cylinder corrugated protective sleeve comprises a dustproof cover body, a waterproof zipper and a suture line; the waterproof zipper is fixed on the dustproof cover body through sewing threads;
and uniformly smearing adhesive on the whole contact surface between the waterproof zipper and the two ends of the dustproof cover body, the suture line position along the extension direction of the suture line and the surface of the exposed suture line on the outer surface of the dustproof cover body, and curing.
Furthermore, the closed tail end of the waterproof zipper is arranged at the large end of the dustproof cover body.
Furthermore, after the adhesive is cured, stainless steel hose clamps are arranged at two ends of the dustproof cover body.
The invention has the beneficial effects that: ripple protective sheath, can realize the change of ripple protective sheath when brake cylinder equipment does not possess the dismouting condition, through the mode direct mount that the unique convenience of zip fastener was dressed, paint special sealing material in zip fastener joint department for guaranteeing to seal.
Zipper type ripple protective sheath can guarantee ripple protective sheath normal use function, satisfied EMUs application again and overhauld's urgent needs, have convenience and progressive concurrently.
The method has the following advantages:
1. the sealing performance of the corrugated protective sleeve is ensured while the corrugated protective sleeve is convenient to replace;
2. the fatigue performance requirement and reliability of the zipper type corrugated protective sleeve are ensured;
3. the low temperature resistance and the high temperature resistance of the zipper type corrugated protective sleeve are ensured;
4. the sewing quality between the corrugated protective sleeve rubber and the zipper is ensured.
Drawings
Fig. 1 is a schematic perspective view of a corrugated protective sleeve for a zipper-type brake cylinder according to the present invention;
fig. 2 is a schematic view of a structure of a zipper type brake cylinder corrugated protective sleeve according to the present invention.
Detailed Description
The embodiment is described with reference to fig. 1 and 2, and the corrugated brake cylinder protective sleeve for the operation and maintenance of the motor train unit comprises a dustproof cover body 1, a waterproof zipper 2 and a suture line 3; the waterproof zipper 2 is fixed on the dustproof cover body 1 through a suture line 3 in a sewing mode;
and uniformly smearing adhesive on the whole contact surface between the waterproof zipper 2 and the two ends of the dustproof cover body 1, the suture line position along the extension direction of the suture line and the surface of the exposed suture line on the outer surface of the dustproof cover body 1, and curing.
The corrugated protective sleeve of the embodiment is firstly cut and separated along the length direction of the dustproof cover body 1; the closed tail end of the waterproof zipper is arranged at the large end of the dustproof cover body, and the waterproof zipper and the corrugated protective sleeve are sewn through a suture line.
In the embodiment, the rubber part of the appearance of the corrugated protective sleeve is black, and the surface is smooth and free from the defects of foreign matter adhesion, scars, bubbles, cracks and the like; the zipper and the rubber base body are firmly sewed, and the defects of local separation, thread separation and the like are avoided; the zipper part is black in color and should be complete without defects such as defects and the like.
The ripple protective sheath described in this embodiment is: removing the damaged bellows protection without removing the brake cylinder; wrapping the zipper type corrugated protective sleeve at the installation position of the original corrugated protective sleeve, and zipping the zipper; special adhesive (silica gel adhesive with model number of 988A) is evenly smeared on the whole contact surface in the two ends of the waterproof zipper and the corrugated protective sleeve, the suture line position along the extension direction of the suture line and the surface of the suture line exposed on the outer surface of the protective sleeve, and after the adhesive is solidified, stainless steel hose clamps are installed at the two ends of the zipper type corrugated protective sleeve, so that the wrapping part of the corrugated protective sleeve is in a sealing state.
This embodiment the ripple protective sheath, after changing the original integral type ripple protective sheath of checking cylinder down, need not pull down clamp from the EMUs, and use zip fastener formula ripple protective sheath directly with the checking cylinder need the sealed position parcel on, reuse zip fastener closed breach, there is the position in gap between sealed zip fastener and the ripple protective sheath with special binder at last, guarantee ripple protective sheath parcel part and be in encapsulated situation. The problem of damaged check cylinder ripple protective sheath can't directly be changed during the EMUs application is solved, the blank of fortune dimension technique has been filled.
