Abstract
Description
Technical Field
[0001] The utility model relates to the field of marine sliding doors, and more specifically, to a lightweight explosion-proof sliding door protection device for protecting ordinary fireproof doors of a marine vehicle cabin. Background Art
[0002] When a ro-ro passenger ship is sailing, the vehicle compartment usually carries various vehicles and cargoes. Once a fire occurs, it is easy to explode. In order to prevent the flame from spreading to the upper construction area, there are usually two types of fire doors used in the bulkheads of the vehicle compartment with fire protection grade requirements: the first type is an ordinary marine fire door, which can only play a conventional fire protection role. Once an explosion occurs in the vehicle compartment, the fire door is easily destroyed and still cannot prevent the spread of flames; the second type is a fire sliding door with a marine certificate. Although it is fireproof and explosion-proof, it is too heavy and most of them are imported products from abroad. The price is expensive and the cost performance is very low. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the embodiment of the utility model provides a lightweight explosion-proof sliding door protection device for protecting the ordinary fire door of the vehicle cabin. By installing another lightweight explosion-proof sliding door outside the ordinary marine fire door of the vehicle cabin, it can not only meet the fire rating requirements of the bulkhead, but also play an explosion-proof protection role for the internal fire door. The sliding door is simple to make, light in weight, easy to open and close, does not affect the passage of people, and does not require a fire certificate, which can effectively solve the problems raised in the above-mentioned background technology. The content of the utility model has been applied to the fire door outside the elevator hall of the vehicle cabin on the Bohai Hengsheng passenger and vehicle ship built by our company.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lightweight explosion-proof sliding door protection device for an ordinary fireproof door of a ship's vehicle cabin, the main body of the device being a lightweight explosion-proof sliding door, consisting of a door leaf and a door frame, both of which are made of 1.5mm stainless steel plates, a second sealing rubber strip and a third rubber sealing strip are arranged between the door leaf and the door frame, an upper guide rail and a lower guide rail are fixed to the upper and lower sides of the door frame, respectively, an upper vertical roller and a lower horizontal roller are respectively installed on the upper and lower end faces of the corresponding door leaf, the upper vertical roller and the lower horizontal roller are respectively placed in the upper guide rail and the lower guide rail for movement to realize the opening and closing of the door, a first sealing rubber strip is lined on the fixed end of the cover and is fixed to the bulkhead with self-drilling and self-tapping screws to prevent water and dust from entering the upper guide rail and affecting the smoothness of the door opening.
[0005] In a preferred embodiment, both left and right sides of the door frame are fixed to the bulkhead by using self-drilling and self-tapping screws.
[0006] In a preferred embodiment, upper and lower end surfaces of the door leaf are respectively mounted with upper vertical rollers and lower horizontal rollers which are respectively placed in upper guide rails and lower guide rails for movement to realize opening and closing of the door.
[0007] In a preferred embodiment, a door lock is installed on the door leaf, and the inner side of the handle is hidden.
[0008] Technical effects and advantages of the utility model:
[0009] Compared with the fireproof sliding door with marine certificate, the solution of installing a lightweight explosion-proof sliding door outside the ordinary marine fireproof door in the vehicle cabin can not only meet the fireproof grade requirements of the bulkhead, but also play the role of explosion-proof protection for the internal fireproof door. The sliding door is simple to make, light in weight, easy to open and close, does not affect the passage of personnel, and does not require a fireproof certificate, which greatly reduces the cost of shipowners and shipyards, and is extremely cost-effective.

DETAILED DESCRIPTION
[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] like Figure 1-4A lightweight explosion-proof sliding door protection device for an ordinary fireproof door of a ship's vehicle cabin is shown. The main body of the device is a lightweight explosion-proof sliding door 22, which is composed of a door leaf 1 and a door frame 2. The door leaf 1 and the door frame 2 are both made of 1.5 mm stainless steel plates. A second sealing rubber strip 15 and a third sealing rubber strip 16 are arranged between the door leaf 1 and the door frame 2. An upper guide rail 4 and a lower guide rail 5 are fixed to the upper and lower sides of the door frame 2, respectively. An upper vertical roller 6 and a lower horizontal roller 12 are respectively installed on the upper and lower end faces of the corresponding door leaf 1. The upper vertical roller 6 and the lower horizontal roller 12 are respectively placed in the upper guide rail 4 and the lower guide rail 5 for movement to realize the opening and closing of the door. The fixed end of the cover 3 is lined with a first sealing rubber strip 13 and is fixed to the bulkhead 21 with self-drilling and self-tapping screws 18 to prevent water and dust from entering the upper guide rail and affecting the smoothness of opening the door.
