Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a safety passage device for a water retaining plate. Background Art

[0002] In today's large-scale infrastructure construction, the foundation is an important link between the superstructure and the foundation. Its construction accuracy and durability directly determine the stability and service life of the entire project. Especially in areas with complex water environments, such as near rivers and coastlines or areas where underwater construction is required, water retaining boards have become an indispensable component of building a safe construction environment. These water retaining boards effectively prevent water intrusion by enclosing the construction area, ensuring the smooth progress of the concrete pouring process and the dryness and stability of the foundation pit.

[0003] However, in actual operation, construction workers face a series of technical and safety challenges when entering the work area surrounded by the water retaining board for daily inspection, maintenance or emergency construction. In the prior art, the methods of entering the area enclosed by the water retaining board mainly include the following: 1. Detour entry: Construction workers enter by finding the preset opening of the water retaining board or the nearest unenclosed area. This method is time-consuming and may not reach the designated location quickly in an emergency, delaying the repair time; 2. Build a temporary bridge: Temporarily build a simple wooden bridge or metal bridge above the water retaining board for personnel to pass. This method requires a lot of time and materials, and the structural stability is difficult to guarantee. Especially in bad weather, safety accidents are very likely to occur.

[0004] In summary, the existing technology has obvious deficiencies in providing safe, efficient and cost-effective solutions for personnel passage, especially in the construction environment of the pier that requires rapid response and high safety standards. Therefore, the development of a new type of safe passage device that can directly cross the top of the retaining plate has become a key requirement for improving construction efficiency, ensuring personnel safety and optimizing cost control.

DETAILED DESCRIPTION

[0022] 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.

[0023] Embodiment 1: As shown in the figure, a safety passage device for a water baffle 4 includes a first ladder 1, a second ladder 2 and a connecting plate 3 for being erected on the upper end of the water baffle 4. The first ladder 1 is fixed to the lower end of the connecting plate 3 and is located on the inner side of the water baffle 4. The second ladder 2 is connected to the lower end of the connecting plate 3 through a quick connection mechanism 5 and is located on the outer side of the water baffle 4. The lower end of the connecting plate 3 is also provided with a clamping mechanism 6 for fastening to the upper end of the water baffle 4.

[0024] Embodiment 2: As shown in the figure, different from Embodiment 1, the clamping mechanism 6 includes a first fixed plate 7, a second fixed plate 8, a first adjusting plate 9, a second adjusting plate 10, a forward and reverse screw rod 11 and an adjusting hand wheel 12. The first fixed plate 7 and the second fixed plate 8 are respectively arranged at the lower end of the connecting plate 3. The forward and reverse screw rod 11 is rotatably connected between the first fixed plate 7 and the second fixed plate 8, and one end of the forward and reverse screw rod 11 passes through the first fixed plate 7 and is coaxially fixed with the adjusting hand wheel 12. The first adjusting plate 9 and the second adjusting plate 10 are respectively threadedly matched with the forward and reverse screw rod 11. A first clamping plate 13 is vertically fixed to the lower end of the first adjusting plate 9, and a second clamping plate 14 is vertically fixed to the lower end of the first adjusting plate 9. A clamping space with adjustable distance is formed between the first clamping plate 13 and the second clamping plate 14.

[0025] In the above structure, the first fixed plate 7 and the second fixed plate 8 serve as the frame of the entire clamping mechanism 6 and are stably arranged at the lower end of the connecting plate 3. The rotatable connection mode of the forward and reverse screw rods 11 not only ensures the smooth adjustment action, but also the design of one end being coaxially fixed with the adjusting hand wheel 12 greatly improves the adjustment efficiency and convenience. The first adjustment plate 9 and the second adjustment plate 10 are threadedly matched with the forward and reverse screw rods 11, so that the adjustment plates can accurately move linearly along the forward and reverse screw rods 11, thereby making the distance between the first clamping plate 13 and the second clamping plate 14 adjustable, which can effectively adapt to water retaining plates 4 of different thicknesses.

[0026] At the construction site, this adjustable clamping space design allows construction workers to quickly adjust the clamping range of the clamping mechanism 6 according to actual needs, thereby ensuring a firm connection between the device and the water baffle 4. By simply rotating the adjustment handwheel 12, the forward and reverse screws 11 drive the adjustment plate and the clamping plate to move in the preset direction, and the clamping width can be easily finely adjusted. This not only optimizes the applicability of the device, but also greatly improves the installation and disassembly efficiency of the device, ensuring that construction workers can quickly enter and exit the construction area in an emergency, effectively improving construction safety and work efficiency.

[0027] In this embodiment, two guide rods 15 are fixed at intervals between the first fixed plate 7 and the second fixed plate 8, the forward and reverse screw rods 11 are located between the two guide rods 15, a first sliding bearing 16 is arranged between the first adjustment plate 9 and each guide rod 15, and a second sliding bearing 17 is arranged between the second adjustment plate 10 and each guide rod 15.

[0028] In the above structure, the stability and accuracy of the entire clamping mechanism 6 are further enhanced by fixing two guide rods 15 between the first fixed plate 7 and the second fixed plate 8, and the structural layout in which the forward and reverse screw rods 11 are located between the two guide rods 15. The first sliding bearing 16 and the second sliding bearing 17 are respectively installed between the first adjustment plate 9 and the second adjustment plate 10 and each guide rod 15. This design optimizes the moving mechanism of the adjustment plate, so that the adjustment plate can slide smoothly and linearly along the guide rod 15 when adjusting the clamping space.

[0029] Specifically, the advantages of this structure are:

[0030] 1. Enhanced stability: The two guide rods 15 provide strong support and guidance for the adjustment plate, ensuring that the moving direction of the adjustment plate always remains straight during the adjustment process, avoiding tilting or deviation caused by uneven adjustment force or improper operation, thereby affecting the clamping effect and safety.

[0031] 2. Improve accuracy: Installing a sliding bearing between the adjustment plate and the guide rod 15 not only reduces the friction resistance during movement, making the adjustment operation easier and smoother, but also improves the adjustment accuracy of the clamping mechanism 6 by precisely controlling the movement distance and position of the adjustment plate, so that the device can better adapt to water retaining plates 4 of different thicknesses.

[0032] 3. Extended service life: The introduction of sliding bearings effectively reduces wear by reducing direct contact and friction between moving parts, extends the service life of the entire clamping mechanism 6 and even the safety channel device, and reduces maintenance costs.

[0033] 4. Convenience of operation: Since the adjustment plate moves more smoothly and combined with the design of the adjustment hand wheel 12, the operator can easily and accurately adjust the size of the clamping space, and can quickly and effectively complete the installation or adjustment of the device even in harsh construction environments or emergency situations.

[0034] In this embodiment, the first handrail assembly 18 is respectively provided on the left and right sides of the first ladder 1. The first handrail assembly 18 includes an integrally formed first transverse tube 19, a first vertical tube 20, a second transverse tube 21 and a second vertical tube 22. The first transverse tube 19 is horizontally fixed to the lower part of the first ladder 1, and the first vertical tube 20 is vertically fixed to the first transverse tube 19. A plurality of first reinforcing tubes 23 spaced apart vertically are also provided between the first vertical tube 20 and the first ladder 1. The second vertical tube 22 is vertically fixed to the upper end of the connecting plate 3, and the second transverse tube 21 is connected between the first vertical tube 20 and the second vertical tube 22.

[0035] The first handrail assembly 18 is composed of an integrally formed first transverse tube 19, a first vertical tube 20, a second transverse tube 21 and a second vertical tube 22, which provides extremely high safety and stability. The first transverse tube 19 is arranged at the lower part of the first ladder 1, providing a reliable gripping point for the user of the ladder, and the first vertical tube 20 is fixed perpendicular to the first transverse tube 19, further strengthening the structural strength of the entire handrail assembly. In particular, a plurality of first reinforcing tubes 23 spaced apart vertically are arranged between the first vertical tube 20 and the first ladder 1. These reinforcing tubes not only increase the stability of the handrail, but also improve the durability and safety of the entire ladder.

[0036] The design of the second vertical pipe 22 enables the handrail assembly to be firmly connected to the upper end of the connecting plate 3, and the second horizontal pipe 21 spanning between the first vertical pipe 20 and the second vertical pipe 22 provides the user with additional support and balance when climbing from the first ladder 1 to the connecting plate 3. This one-piece structural design makes the entire handrail assembly not only strong and durable, but also simple and consistent in shape, ensuring the stability and safety of the user during the climbing process.

[0037] In this embodiment, second handrail assemblies 24 are respectively provided on the left and right sides of the second ladder 2. The second handrail assembly 24 includes an integrally formed third transverse tube 25, a third vertical tube 26 and a fourth transverse tube 27. The third transverse tube 25 and the fourth transverse tube 27 are respectively fixed on the second ladder 2 at intervals up and down. The third vertical tube 26 is connected between the third transverse tube 25 and the fourth transverse tube 27, and at least one second reinforcing tube 28 is provided between the third vertical tube 26 and the second ladder 2.

[0038] In the above structure, the second ladder 2 is equipped with a third transverse tube 25, a third vertical tube 26 and a fourth transverse tube 27. This structural design optimizes the safety and stability of the second ladder 2, and provides reliable and sturdy support and assistance for the user. The third transverse tube 25 and the fourth transverse tube 27 are respectively fixed on the second ladder 2 at intervals up and down, providing double hand support points when ascending or descending along the ladder, which not only increases the stability of the user during vertical movement, but also improves the overall climbing safety.

[0039] The third vertical tube 26 is connected between the third horizontal tube 25 and the fourth horizontal tube 27, forming a solid supporting structure, providing additional structural strength for up and down movement. More importantly, at least one second reinforcing tube 28 is arranged between the third vertical tube 26 and the second ladder 2. This design not only further strengthens the structural connection between the handrail assembly and the ladder, and enhances the durability of the entire ladder, but also optimizes the mechanical distribution, reduces the distortion or deformation that may occur during frequent use, and extends the service life of the entire device.

[0040] Embodiment 3: As shown in the figure, the difference from Embodiment 2 is that two protruding plates 29 extend upward from the upper end of the second ladder 2, and two spaced-apart limit seats 30 are provided at the lower end of the connecting plate 3. The quick-connect mechanism 5 includes a locking bolt 31 and a locking nut 32. The protruding plate 29 is inserted into the corresponding limit seat 30, the locking bolt 31 is connected between the protruding plate 29 and the limit seat 30, and the locking nut 32 is screwed onto the locking bolt 31.

[0041] Through the combination of the protruding plate 29, the limit seat 30, the locking bolt 31 and the locking nut 32, the connection method between the second ladder 2 and the connecting plate 3 is optimized, which has significant structural and operational advantages. This design makes the installation and disassembly process of the second ladder 2 more convenient and quick, while also ensuring the stability and safety of the connection.

[0042] Specifically, the two protruding plates 29 extending upward from the upper end of the second ladder 2 are designed to precisely match the two spaced limit seats 30 at the lower end of the connecting plate 3. This matching relationship not only ensures that the second ladder 2 can be quickly docked with the connecting plate 3 at the correct position, but also achieves initial stable positioning between the ladder and the connecting plate 3 through the mutual cooperation between the protruding plates 29 and the limit seats 30. Furthermore, by passing the locking bolt 31 through the protruding plate 29 and connecting it to the limit seat 30, and then screwing the locking nut 32 on the locking bolt 31, the second ladder 2 can be quickly and firmly locked. This locking mechanism not only simplifies the installation steps, but also facilitates quick disassembly when needed, providing an efficient workflow for the construction site.

[0043] In this embodiment, the first ladder 1 and the second ladder 2 are respectively provided with anti-slip textures.

[0044] The main function of the anti-slip texture is to increase the friction of the ladder surface, thereby improving safety, especially in wet or muddy conditions often encountered on construction sites, effectively reducing the risk of slip accidents.

[0045] In this embodiment, a cushion block 33 is further provided at the lower end of the connecting plate 3 so that the connecting plate 3 can better contact with the upper end of the water retaining plate 4, so as to enhance the overall stability.

[0046] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
