Description

TECHNICAL FIELD

[0001] The present application relates to the field of ship technology, in particular to a safe passage for a binding bridge middle group and a design method thereof. BACKGROUND

[0002] Container ship, also known as "cargo ship", is a ship that can be used to load international standard containers in a broad sense, and is a full container ship whose all cabins and decks are used to load containers in a narrow sense. The container ship has many binding bridges. The binding bridge is a single or multi-layer steel bridge structure arranged in the longitudinal spacing of the container and along the width direction of the ship, which is a key equipment in the container ship cargo binding system. Most of the binding bridges of the container ship are large binding bridges, and the length of some types of binding bridges reaches 51m, the main width (thickness) is 1.35m, the height is 16.5m, and the weight is about 100t. The related parameters of the remaining types of binding bridges are slightly different, but are roughly similar.

[0003] The construction and assembly of the binding bridge are carried out in different places. For example, the binding bridge is constructed in one factory area, the middle group is assembled into left and right half bridges, and the corresponding iron fittings, electrical fixtures and the like are installed, and then delivered to another factory area for sanding, painting, total assembly and hoisting of the half bridge to the ship to complete the operation. The half bridge middle group of the binding bridge adopts the industry common side-standing tire assembly mode, the left and right bridges are separated by about 500mm, the main body of the tire frame is 556mm away from the ground, the top side plate of the top walking platform is about 1.7m away from the ground, and the highest point of the top column is 2m away from the ground.

[0004] Since the top main plate (as the top passage and operation surface) is not more than 2m away from the ground, it does not reach the range of the hard requirement of the industry safety management that requires the whole safety protection net plate (step plate) or the anti-falling fence chain to be laid, and the middle group size is large and the range is wide. Therefore, the existing technology is to directly construct, pass and inspect on the top main structure without additional safety protection measures, which cannot guarantee 100% safety. In the case that the safety fence chain is not laid on the suspended edge of the top side plate of the walking platform, there is a risk of falling and injury in the middle group operation construction and inspection process.

[0049] The binding bridge is a key equipment in the container ship cargo binding system, which can not only shorten the length of the binding rod, binding chain or steel wire rope used for binding, but also significantly improve the binding effect while facilitating the implementation of the binding operation. The shear wall type binding bridge is widely praised by users due to its simple structure design, good stress condition and small occupation of ship space position. At present, the side-standing upper tire assembly mode is adopted in the shear wall type binding bridge middle group operation. The side-standing upper tire assembly mode is a common binding bridge middle group mode in the prior art, which will not be described here.

[0050] Figure 1 A top view schematic diagram of the binding bridge in the middle group state provided by the embodiment is shown. As shown in Figure 1 The binding bridge includes a left bridge 100 and a right bridge 200, and the left bridge 100 and the right bridge 200 are arranged in axial symmetry. The left bridge 100 and the right bridge 200 each include a walkway 10, a column 30 and a shear wall 20. Each layer of walkway 10 extends in the transverse direction of the binding bridge, and multiple layers of walkway 10 are arranged in the longitudinal direction of the binding bridge. The column 30 extends in the longitudinal direction of the binding bridge and is used to connect the multiple layers of walkway 10. Multiple columns 30 are arranged in the transverse direction of the binding bridge and are used to ensure the structural strength and stability of the walkway 10. The shear wall 20 connects the multiple layers of walkway 10 and is used to bear the transverse load of the binding bridge.

[0051] In order to improve the safety of the binding bridge middle group operation and the inspection process, the present embodiment provides a binding bridge middle group safety passage and a design method thereof, which aims to design a safe route according to the structural characteristics and middle group form of the binding bridge, form a clear guidance scheme, and then carry out the semi-bridge middle group overall construction and inspection work, reduce the risk of falling, and ensure the safety of the operating personnel.

[0052] Continuing as Figure 1As shown, the binding bridge middle group safety channel includes multiple rows of transverse safety channels 1 and multiple columns of longitudinal safety channels 2, at least two columns of longitudinal safety channels 2 are symmetrically arranged at the left and right end portions of the binding bridge, so as to ensure that the longitudinal safety channels 2 and the transverse safety channels 1 can form a closed loop, thereby facilitating the operation of the operating personnel. Each row of transverse safety channels 1 includes a transverse channel 11 and a transverse side guard 12, the transverse channel 11 extends along the transverse direction of the binding bridge, and the transverse side guards 12 are arranged on both sides of the transverse channel 11, so as to prevent the operating personnel from falling from both sides of the transverse channel 11 and improve safety. Each column of longitudinal safety channels 2 includes a longitudinal channel 21 and a longitudinal side guard 22, the longitudinal channel 21 extends along the longitudinal direction of the binding bridge, and the longitudinal side guards 22 are arranged on both sides of the longitudinal channel 21, so as to prevent the operating personnel from falling from both sides of the longitudinal channel 21 and improve safety.

[0053] Preferably, in order to facilitate the operating personnel to get on the binding bridge to perform middle group operation and inspection work, a ladder 3 is arranged on both sides of the binding bridge. The ladder 3 can be an existing tool scaffold ladder. The binding bridge middle group safety channel further includes a rain shelter tool 4, which includes clamping columns and a rain shelter curtain, a plurality of clamping columns are fixed on the square tube of the binding bridge, and the rain shelter curtain is installed on the plurality of clamping columns. Exemplarily, the clamping column can be a 1.65m high clamping column.

[0054] The design method of the binding bridge middle group safety channel provided by the embodiment includes the following steps:

[0055] Transverse safety channel 1 design: multiple rows of transverse channels 11 are designed on the walkway top side plate 101 and the shear wall 20, the transverse channels 11 extend along the transverse direction of the binding bridge, and transverse side guards 12 are arranged on the suspended sides of the transverse channels 11;

[0056] Longitudinal safety channel 2 design: multiple columns of longitudinal channels 21 are designed between the multiple layers of walkway top side plates 101, the longitudinal channels 21 extend along the longitudinal direction of the binding bridge, and longitudinal side guards 22 are arranged on the suspended sides of the longitudinal channels 21.

[0057] In the step of designing the transverse safety channel 1: a step plate 111 is arranged between the left bridge 100 and the right bridge 200 and corresponds to the walkway top side plate 101, the walkway top side plate 101 and the step plate 111 corresponding thereto serve as the main channel of the first kind of transverse channel 11; a net plate 112 is arranged on the hole of the shear wall 20, and the walkway top side plate 101 and the net plate 112 corresponding thereto serve as the main channel of the second kind of transverse channel 11.

[0058] Figure 2 A cross-sectional view at A-A is shown. Figure 1 As shown in the cross-sectional view at A-A, Figure 2 In combination with Figure 1As shown, since the interval between the left bridge 100 and the right bridge 200 is about 500mm, it is inconvenient for the workers to pass through, therefore, among the multiple rows of transverse passages 11, some of the transverse passages 11 include the walkway top side plate 101 and the stepping plate 111 which is set up between the left bridge 100 and the right bridge 200 and corresponds to the walkway top side plate 101.

[0059] Figure 3 As shown Figure 1 the cross-sectional view at B-B. As shown Figure 3 As shown Figure 1 As shown, since the shear wall 20 is a complete planar structure, there is no need to add a passing component, therefore, some of the transverse passages 11 include the walkway top side plate 101 and the shear wall 20. Preferably, the part of the transverse passage 11 formed by the shear wall 20 also includes the mesh plate 112 which is set on the hole of the shear wall 20. When there is a hole with a larger size on the shear wall 20, by setting the mesh plate 112, the foot of the worker can be prevented from being stuck in the hole, and the safety is improved.

[0060] The transverse side protection 12 can be a handrail guard, can also be a protective chain which is pulled, and can also be a combination of the handrail guard and the protective chain, all of which can play a protective role. Exemplarily, as shown Figure 3 As shown Figure 1 As shown, one side of the transverse passage 11 uses the handrail guard as the transverse side protection 12, and the other side uses the protective chain as the transverse side protection 12. In this embodiment, one side of the walkway top side plate 101 of the tied bridge is provided with the handrail guard, and there is no need to re-set the handrail guard or pull the protective chain. The other side of the walkway top side plate 101 is suspended, and the handrail guard or the protective chain needs to be set. Considering that the construction cost of the protective chain is low, the protective chain can be pulled on the suspended side.

[0061] In the step of designing the longitudinal safety passage 2: the walk bridge 211 is set up between the multiple layers of walkway top side plates 101, the walk bridge 211 serves as the longitudinal passage 21, and the protective chain on both sides of the walk bridge 211 serves as the longitudinal side protection 22.

[0062] As shown Figure 3 As shown Figure 1As shown, the longitudinal passage 21 comprises a walkway 211 arranged on the top side plate 101 of the multi-layered walkway. The longitudinal side protection 22 can be a handrail guard, a protective fence, or a combination of the handrail guard and the protective fence, all of which can play a protective role. In this embodiment, the protective fence is used as the longitudinal side protection 22 on both sides of the longitudinal passage 21 to facilitate the safe passing of the operating personnel through the longitudinal safety passage 2 and improve the operating safety. Preferably, the left bridge 100 is provided with one longitudinal safety passage 2 on each of the left and right sides thereof, and the right bridge 200 is provided with one longitudinal safety passage 2 on each of the left and right sides thereof. Of course, in other embodiments, the number of the longitudinal safety passage 2 can also be any other number, which can be designed according to the needs and will not be exemplified here.

[0063] Optionally, a spacer is arranged between the walkway 211 and the walkway top side plate 101. On the one hand, the spacer can separate the walkway 211 and the walkway top side plate 101 to facilitate the inspection of the welding quality of the walkway top side plate 101 by the operating personnel during the inspection; on the other hand, the spacer can also reduce the indentation and scratch of the walkway 211 on the walkway top side plate 101, thereby ensuring the appearance quality of the walkway top side plate 101. Exemplarily, the spacer can be a 0.7m*0.3m*0.25m spacer.

[0064] Optionally, the net plate 112 and the step 111 can be a step with hooks. Figure 4 A top view of the step with hooks provided in this embodiment is shown. Figure 5 A side view of the step with hooks provided in this embodiment is shown. As shown, Figures 4 to 5 As shown, the step with hooks is provided with hook-shaped portions at both ends thereof to facilitate the installation of the step 111, ensure the stability of the step 111, reduce the shaking of the step 111, and improve the safety. Exemplarily, the step with hooks can be a 2m long step with hooks for surfing.

[0065] Optionally, the walkway 211 can be a bridge plate structure with a stand. Figure 6 A top view of the walkway 211 provided in this embodiment is shown. Figure 7 A side view of the walkway 211 provided in this embodiment is shown. As shown, Figures 6 to 7 As shown, the walkway 211 comprises a passage plate 2111 and fence stand columns 2112 installed on both sides of the passage plate 2111, both sides of the passage plate 2111 are provided with mounting tubes, the fence stand columns 30 are detachably inserted into the mounting tubes, the fence stand columns 2112 are provided with hook-shaped structures, and the hook-shaped structures are used to facilitate the installation of the protective fence to form the protective fence to prevent the operating personnel from falling. Exemplarily, the walkway 211 is a 9m long and 0.75m wide work walkway, and the stand 30 is welded on both sides of the work walkway. The fence is a galvanized iron chain with a diameter or thickness of 4mm.

[0066] For the convenience of understanding, the construction process of the safety channel in the binding bridge middle group provided by the embodiment is as follows:

[0067] First, the walkway 10 is arranged on the tire frame 300;

[0068] After the two side plates of the binding bridge are hoisted and closed, the fall ladders 3 on the left and right sides of the binding bridge are erected;

[0072] The clamping column of the rain shelter tool 4 is installed at the corresponding position of the square tube structure of the binding bridge;

[0073] The chain is pulled to form the horizontal side protection 12 and the longitudinal side protection 22.

[0074] Figure 8 The operation schematic diagram of the chain pulling provided by the embodiment is shown. As shown in Figure 8 In order to facilitate the pulling of the chain, the chain is installed in its entirety, and is continuously pulled according to the arrow direction in Figure 8 , and is cut off at the end. The principle of chain pulling is that the horizontal channel 11 part should be vertically dropped to the bottom surface to avoid affecting the walking of the workers in the longitudinal channel 21.

[0075] After the safety channel is laid, the related assembly, electric welding, polishing, and blasting of the binding bridge middle group are carried out, then the owner's completion inspection is organized, and the closed-loop inspection tail problem is handled; after the inspection tail problem is handled and rechecked, all safety channel materials are removed and stored for the next bridge, and then the half bridge is hoisted out of the tire for subsequent work before the half bridge is delivered.
