Description

TECHNICAL FIELD

[0001] The utility model belongs to shipbuilding technical field, especially relate to a detachable protection ramp of deck pipe valve. BACKGROUND

[0002] The two sides of the deck of the ship are provided with a deck safety passage from the bow to the stern, which penetrates the entire deck. At present, due to the limited space of the ship or the arrangement needs, various pipe systems cannot completely avoid the deck safety passage. In order to consider the safety of the passing personnel and avoid the trampling of the pipe valve in the later cross operation, it is usually necessary to take necessary protection measures for the pipe.

[0003] The most widely used pipe valve protection measure on the existing ship is to increase a fixed steel plate platform within the scope of the pipe. The platform is usually designed as a step type, and the height and width cover the area where the pipe valve is located. Therefore, the platform can be installed only after the pipe is laid, and is usually installed during the large closing stage. However, the cabin where the deck safety passage of the ship is located is a ballast tank, and at this time, the ballast tank has been finished painting. The subsequent welding will inevitably damage the paint of the ballast tank, which does not conform to the current design concept of the integrity of the ballast tank.

[0004] Secondly, with the innovation of shipbuilding technology and the increasing popularity of individual requirements of ship owners, the existing technology has certain disadvantages for the later maintenance, repair, replacement and safety passage integrity of the pipe valve. For the ship deck on both sides with cabin washing needs, usually only one portable cabin washing machine is provided. One cabin washing machine needs to consider all cargo holds. The cabin washing machine reaches each cabin by pushing on the deck safety passage to meet the washing needs. Furthermore, the current filling ship, chemical ship and oil ship need to use the deck safety passage to roll to the required place due to the later needs of the crew. The traditional design can only rely on the crew to move and lift to cross the platform. This cumbersome operation not only wastes time and effort, but also increases the safety hazard. UTILITY MODEL CONTENTS

[0005] In view of the above problems, the utility model provides a detachable protection ramp of deck pipe valve, which can meet the protection of the pipe system without damaging the ballast tank, and can also consider the later maintenance, repair and replacement. In addition, it can facilitate the various use needs of the later crew pushing the cart and rolling the barrel. The detachable pipe protection ramp has the advantages of simple structure, low construction cost, high safety and strong protection measures.

[0009] Further, the second slope opening support has an inverted U-shaped longitudinal section, and upper portions of the support base on both sides in a length direction of the slope body are detachably connected with lower ends of side walls of the second slope opening support.

[0010] Further, the support base is composed of two groups of T-shaped pieces, two T-shaped pieces in each group are oppositely arranged in the length direction of the slope body, and lower portions of the side walls of the second slope opening support are detachably connected with upper ends of vertical portions of the T-shaped pieces through bolts and nuts.

[0011] Further, the lower end of the slope section is arranged in a spaced manner with the upper end surface of the deck.

[0012] Further, the distance between the lower end of the slope section and the upper end surface of the deck is 13mm-16mm.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figs. 1-3 As shown, a detachable protective ramp for a deck valve includes a ramp body 1 and a support base 2. The support base 2 is fixedly connected to a deck 3. The ramp body 1 has a straight section 11 and sloping sections 12 located on both sides of the straight section 11. The lower end of the straight section 11 is detachably connected to the support base 2. The deck valve is located directly below the straight section 11.

[0022] Both the straight section 11 and the sloping section 12 include a top plate 101. A plurality of first ramp support 102 are fixedly fixed at intervals along the width direction of the ramp body 1 on the lower end surface of the top plate 101 located in the sloping section 12. A plurality of second ramp support 103 are fixedly fixed at intervals along the width direction of the ramp body 1 on the lower end surface of the top plate 101 located in the straight section 11. The upper end of the first ramp support 102 abuts against the upper side wall of the second ramp support 103. The lower ends of the plurality of second ramp supports are connected to the support base 2. The longitudinal section of the second ramp support 103 is inverted U-shaped. The upper part of the support base 2 is detachably connected to the lower ends of the side walls of the second ramp support 103 on both sides along the length direction of the ramp body 1.

[0023] In this embodiment, a ramp is designed in the area where the pipeline system needs protection. The upper surface of the ramp is made of corrugated steel plate, and the back is constructed with angle steel to build a frame (i.e., the first ramp support 102 and the second ramp support 103) to meet the strength requirements of the ramp itself. The length L of the ramp is set according to the pipeline route, and a straight section 11 is designed in the area where the pipeline is located. The width of the straight section 11 must not be less than the width of the deck safety passage and the width of the equipment passage itself (normally 700mm~1000mm). The width of the straight section 11 is designed according to the location, and under the premise of no interference, the principle of prioritizing the gentleness of the slope on both sides is adopted. The smaller the slope, the higher the safety factor.

[0024] It is understandable that the deck valve is located directly below the straight section 11, while the ramp sections 12 on both sides do not affect walking in the deck safety passage.

[0025] Furthermore, the support base 2 is composed of two sets of T-shaped parts arranged in pairs. The two T-shaped parts in each set are arranged at intervals relative to each other along the length of the ramp body 1. The lower part of the two side walls of the second ramp support 103 is detachably connected to the upper end of the vertical part of the T-shaped part by bolts and nuts.

[0026] Understandably, the support base 2 welded to the ramp body 1 and the deck surface is detachable and fixed by bolts, which facilitates later inspection, maintenance, and replacement. At the same time, the base is low in height, which does not affect the sectional transfer and hoisting. Moving the base installation process to the section in advance effectively solves the problem of paint damage in the ballast tank.

[0027] Furthermore, the lower end of the ramp section 12 is spaced apart from the upper surface of the deck 3; the distance between the lower end of the ramp section 12 and the upper surface of the deck 3 is 13mm~16mm. In this embodiment, the lower end of the ramp section 12 is approximately 15mm above the deck 3.

[0028] Understandably, when heavy objects pass through this ramp, the ramp body 1 will not make hard contact with the deck 3, thus preventing damage to the deck 3 and indirectly protecting the deck structure and paint.

[0029] Furthermore, the top plate 101 is a perforated steel plate, and a plurality of square steel bars 4 extending in the width direction of the ramp are provided at intervals on the perforated steel plate; the length of the square steel bars 4 is less than the width of the ramp, and they are arranged along the same center line as the ramp.

[0030] Understandably, square steel bars are welded onto the steel plate on the upper surface of the ramp to further prevent slipping.

[0031] In this embodiment, anti-slip square steel is designed to be approximately 400mm long in the middle of the platform and spaced approximately 300mm apart, mainly concentrated in the area where people walk, to prevent safety hazards caused by rain or oil residue.

[0032] Those skilled in the art should understand that the above description is merely a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
