Description

Technical Field

[0001] This utility model relates to the field of temporary traffic ladders for the maintenance of water conveyance corridors in locks, specifically to a quick-assembly aluminum alloy traffic ladder device for water conveyance corridors in locks. Background Technology

[0002] Large, high-head ship locks typically employ a decentralized water conveyance system to improve water conveyance efficiency and flow conditions within the lock chamber. This decentralized system includes a main corridor and branch corridors; some systems also include a collection corridor. At the connection between the main corridor / collection corridor and the branch corridor, a diversion point is located. This diversion point has two levels: the upper level connects to the branch corridor, and the lower level connects to the main corridor / collection corridor, forming a steep ramp. When the lock is closed for maintenance, temporary access stairs must be erected to descend from the branch corridor to the main corridor / collection corridor.

[0003] The access passage for water conveyance corridor maintenance is usually located in the inlet or outlet of the gate chamber bottom plate. It is small in size and can only be used by one person at a time. The size of the tools and materials that personnel can carry is greatly limited. The construction of traditional temporary access ladders mainly relies on assembled steel pipes and fasteners. Due to the bulky and size-restricted components, they need to be transported one by one, resulting in low transportation efficiency.

[0004] The transportation ladder is constructed using assembled steel pipes, and fasteners are tightened one by one with torque wrenches. There are no other available devices. This method of assembly or disassembly is time-consuming and labor-intensive, usually taking a whole day. It seriously affects the maintenance process of the lock's water conveyance corridor, fails to meet the demand for rapid lock maintenance, and impacts the efficiency of shipping.

[0005] When constructing the steel pipe access ladder, holes need to be drilled in the bottom slab and side walls of the corridor, and the access ladder is fixed by bolt anchoring, which causes a certain degree of damage to the hydraulic structure of the water conveyance corridor.

[0006] The steps of the steel pipe access stairs are made of circular steel pipes, which have a small stress area. In addition, the water conveyance corridor is dark and slippery, posing a significant safety hazard to people going up and down the access stairs.

[0007] The steel pipe traffic stairs consist of steps, inclined beams, guardrails, and support columns. All components are made of steel pipes, making it difficult to standardize specifications and models, hindering modularization, and making categorized storage difficult. The corridor is damp, and moisture corrosion can easily cause the steel pipes to rust and deform. Utility Model Content

[0033] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0034] Example 1: See Figure 1-11 A rapid-assembly aluminum alloy traffic ladder device for a lock water conveyance corridor includes a rapid traffic ladder 1. The rapid traffic ladder 1 is equipped with an adjustable bottom support 2. The upper end of the adjustable bottom support 2 is inserted into a bottom side beam 4. The bottom side beams 4 on the left and right sides are arranged side by side in parallel. The top end of the bottom side beams 4 is inserted into a top side beam 14. The lower ends of the bottom side beams 4 and the top side beams 14 are horizontally and vertically inserted into a low folding ladder support 6 and a high folding ladder support 11 arranged in parallel. The bottom side beams 4 and the top side beams 14 are fixed horizontally and crosswise with cross braces 9, lower diagonal braces 10 and upper diagonal braces 12 by clamps. The adjustable bottom support 2 is plugged into the bottom ends of the low folding ladder support 6 and the high folding ladder support 11. Multiple sets of movable steps 3 and double-width frames 13 are fixed between the bottom side beam 4 and the top side beam 14 of the ladder by transverse clamps. The top movable step 17 is fixed to the top of the top side beam 14 by transverse clamps. The top movable step 17 is fixed to the top platform 15 by transverse clamps. The upper ends of the vertical tubes of the bottom side beam 4, the top side beam 14, and the top platform 15 are vertically plugged into the inclined guardrail posts 7 and the horizontal guardrail posts 16. The inclined guardrail posts 7 and the horizontal guardrail posts 16 are fixed to the handrail inclined tube 5 and the handrail horizontal tube 18 by transverse universal buckles 8. By adopting the above device, transportation is convenient, disassembly and assembly are easy, and the structure is stable. The connection method of plugging and clamps allows for flexible and rapid erection, realizing the purpose of rapid transportation, erection, and safe passage of the traffic ladder for water conveyance corridor maintenance.

[0035] Furthermore, the rapid transit elevator 1 is equipped with an adjustable bottom support 2, which is stably placed on the ground of the lower level of the water diversion channel of the lock. The upper end of the adjustable bottom support uses a screw and nut combination. By rotating the nut, the support height can be adjusted appropriately to level the rapid transit elevator. The bottom of the adjustable bottom support is equipped with a rubber anti-slip pad.

[0036] Furthermore, the adjustable bottom support 2 is connected to the upper end of the ladder bottom side beam 4, and the left and right ladder bottom side beams are arranged side by side in parallel. The lower end of the vertical tube of the ladder bottom side beam 4 is connected to the low folding ladder support 6 horizontally and vertically. The folding ladder support is constructed using a double folding frame with a bending head, and can be folded 180 degrees, making the folding support convenient and quick to transport, assemble, and store.

[0037] Furthermore, the adjustable bottom support 2 is inserted into the bottom end of the low-folding ladder support 6, and multiple sets of movable steps 3 and double-width frames 13 are fixed across the ladder bottom side beam 4 by clamps. The top side beam 14 is inserted into the top side beam 14 of the ladder. The movable step panels are made of aluminum checkered plate, which is non-slip and firm, allowing people to walk on it. The double-width frames are a connecting and reinforcing device for the left and right side beams, which can prevent the side beams from swaying or tilting.

[0038] Furthermore, the lower end of the vertical tube of the top side beam 14 is horizontally and vertically connected to the high folding ladder support 11, and the bottom end of the high folding ladder support 11 is connected to the adjustable bottom support 2. The top side beam 14 is horizontally fixed with clamps to multiple sets of movable steps 3 and double-width frames 13. The bottom side beam and the top side beam have the same structure, are set separately, and are connected by a socket to reduce the overall length of the fast passageway side beam and facilitate access to and from the corridor.

[0039] Furthermore, the top of the ladder side beam 14 is secured by a clamp across the top of the movable top step 17, and the movable top step 17 is secured by a clamp across the top platform 15. The top platform 15 is stably placed on the floor of the upper corridor of the water diversion channel of the lock. The difference between the movable top step and the movable top step is that the movable top step has a notch on one side of its platform panel, which can be used for clamping on one side of the top platform. The top platform is composed of two aluminum checkered plates, with vertical pipes installed on both longitudinal edges and a bending head installed on the back, allowing it to be folded and unfolded longitudinally for easy transportation and storage. The top platform is placed on the floor of the upper corridor of the diversion channel, allowing normal passage for personnel, going up to the branch corridor and down to the main corridor or the converging corridor.

[0040] Furthermore, the lower ends of the vertical pipes of the bottom side beam 4 and the top side beam 14 of the ladder are arranged in parallel with the low folding ladder support 6 and the high folding ladder support 11, which are connected by vertical splicing. The low folding ladder support 6 and the high folding ladder support 11 are fixed with cross-bracing clamps that cross each other to secure the horizontal brace 9, the lower diagonal brace 10, and the upper diagonal brace 12. The horizontal brace, the lower diagonal brace, and the upper diagonal brace between the double folding supports are provided to fix the double folding ladder supports and prevent swaying and tilting.

[0041] Furthermore, the upper ends of the vertical tubes of the bottom side beam 4 and the top side beam 14 of the ladder are vertically connected to the inclined guardrail posts 7. The inclined guardrail posts 7 are fixed to the handrail inclined tubes 5 by horizontal universal buckles 8. The upper ends of the vertical tubes of the top platform 15 are vertically connected to the horizontal guardrail posts 16. The horizontal guardrail posts 16 are fixed to the handrail horizontal tubes 18 by horizontal universal buckles 8. The guardrail posts fix the handrail tubes, and the handrails on both sides allow people to pass safely.

[0042] Furthermore, the dimensions of the rapid transit elevator 1 are designed according to the maximum height difference of the water conveyance corridor diversion outlet. By removing a small number of movable steps and adjusting the guardrails, top movable steps, and top platform, the overall height of the rapid transit elevator can be reduced to accommodate different height differences at the water conveyance corridor diversion outlet, basically meeting the passage requirements of the diversion outlet.

[0043] Furthermore, all components of the rapid transit elevator 1 are connected by socket and clamp methods, allowing for easy manual disassembly and assembly, which is efficient and quick.

[0044] Furthermore, the individual components of the rapid transit elevator 1, such as the aluminum alloy round tube, are of uniform specifications and can be classified, painted, or marked, making it convenient to categorize and centrally store them in equipment storage boxes.

[0045] The working process and working principle of this utility model are as follows: By adopting the above-mentioned traffic ladder device, rapid transportation and assembly are possible. When the water conveyance corridor needs to be repaired, a rapid traffic ladder 1 is erected between the ground of the lower corridor at the diversion point and the ground of the upper corridor at the diversion point. Movable steps 3 are installed between the rapid traffic ladders 1, and the upper and lower corridors can be accessed by moving back and forth through the movable steps 3, so as to realize passage within the corridor.
