Description

Technical Field

[0001] This utility model relates to the field of bridge building machine technology, and in particular to a safety protection platform for bridge building machines. Background Technology

[0002] New railway bridges often employ cantilevered prestressed concrete continuous beam structures when crossing existing highways or railways. To achieve this construction method, bridge-building machines are widely used in railway construction for cantilever continuous beams. When bridge-building machines operate at heights, construction workers must utilize safety platforms to perform their tasks.

[0003] Existing bridge-building equipment, such as the novel continuous beam cantilever bridge-building machine disclosed in Chinese invention patent CN117513185A, features a corridor for construction workers located inside an inverted U-shaped gantry. However, this design suffers from steep (mostly 90°) ladders for workers to move up and down, and is further hampered by the inverted U-shaped gantry structure, making movement difficult and posing safety hazards. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing bridge-building machine safety protection platforms, which are not convenient for construction personnel to move, and to provide a bridge-building machine safety protection platform.

[0005] In a first aspect, this utility model provides a safety protection platform for a bridge-building machine, comprising:

[0006] The middle platform is located at the bottom of the inverted U-shaped gantry of the bridge-building machine, and is located on the outside of the inverted U-shaped gantry of the bridge-building machine;

[0007] The bottom platform is located at the bottom of the bridge-building machine. The bottom platform is connected to the middle platform through a first ladder. The angle between the first ladder and the horizontal plane is 45°~60°.

[0008] An outer formwork truss platform is located above the middle platform. The middle platform is connected to the outer formwork truss platform via a second ladder. The angle between the second ladder and the horizontal plane is 45° to 60°.

[0009] The top platform is located on top of the main load-bearing beam of the bridge-building machine. The top platform is equipped with a third ladder, and the angle between the third ladder and the horizontal plane is 60°~70°.

[0010] Guardrails are installed on the middle platform, the bottom platform, the outer formwork truss platform, and the top platform.

[0011] The bridge-building machine safety protection platform provided by this utility model sets the middle platform on the outside of the inverted U-shaped gantry, avoiding the restriction of the gantry structure on the movement of construction personnel, allowing construction personnel to move more freely on the platform, no longer restricted by the narrow space inside the gantry, and greatly improving the convenience of operation.

[0012] By setting up an intermediate platform between the outer formwork truss platform and the bottom platform, construction workers no longer need to climb directly from the bottom platform to the outer formwork truss platform. Instead, they can first climb to the intermediate platform and then climb to the outer formwork truss platform, avoiding the inconvenience of going up and down caused by traditional vertical cage ladders. The angles of the first and second ladders are designed to be 45°~60°, and the angle of the third ladder is 60°~70°. This gentler inclination angle significantly reduces the difficulty of climbing, making it easier for construction workers to move up and down, reducing physical exertion, improving work efficiency, and significantly reducing the safety hazards of climbing.

[0013] The bridge-building machine safety protection platform provided by this utility model constructs a multi-layered working system by setting up a bottom platform, a middle platform, an outer formwork truss platform, and a top platform. These platforms are located at different heights of the bridge-building machine, facilitating construction personnel to carry out work at different heights of the bridge-building machine.

[0014] The bridge-building machine safety protection platform provided by this utility model is equipped with guardrails on each platform, which effectively prevents construction workers from falling from heights due to slips or accidents in high-altitude working environments, and significantly improves the safety of operation.

[0015] Preferably, there are two intermediate platforms, which are symmetrically arranged at the bottom of the inverted U-shaped gantry of the bridge-building machine.

[0016] With this structural design, the two symmetrical mid-level platforms provide construction workers with a larger working space, making it easier for them to move around and improving construction efficiency.

[0017] Preferably, there are two external formwork truss platforms, which are symmetrically arranged on both sides of the inverted U-shaped gantry of the bridge-building machine.

[0018] This structural setup, with its dual-platform design, provides construction workers with more operating space, allowing multiple workers or workers of different trades to work simultaneously, facilitating worker movement and improving construction efficiency.

[0019] Preferably, it also includes a bottom support platform, which is installed below the bottom platform and completely covers the bridge-building machine.

[0020] With this structural design, during construction, materials or debris may fall from above. The bottom support platform, located below the bottom platform, can effectively prevent these objects from falling. The bottom support platform completely covers the bridge-building machine, meaning the bridge-building machine falls entirely within the projected area of ​​the bottom support platform. This effectively protects personnel and equipment below from the impact of falling objects, ensuring the safety of the construction site.

[0021] Preferably, the bottom platform is a box-shaped structure with the opening facing upwards.

[0022] The box-shaped structure with its opening facing upwards can effectively capture objects, tools, or people falling from above, preventing them from falling directly to the area below, significantly reducing the risk of fall accidents and protecting the safety of construction workers and equipment below.

[0023] Preferably, the bottom support platform includes a base plate and side walls, with the side walls installed along the edges of the base plate, and the bottom support platform is a box-shaped structure with the opening facing upwards.

[0024] The bottom support platform adopts an upward-facing box-shaped structure composed of a base plate and side walls, forming a container-like space that can hold objects falling from above, preventing them from falling directly to the area below, thereby protecting construction workers and equipment from injury.

[0025] Preferably, the sidewall is fitted with several reinforcing ribs.

[0026] With this structural design, the addition of reinforcing ribs enables the sidewalls to effectively resist bending or torsional deformation when subjected to large loads, ensuring the stability of the structure.

[0027] Preferably, the guardrail includes a plurality of vertical bars and a plurality of horizontal bars, the vertical bars and the horizontal bars being arranged alternately.

[0028] This structural design, with vertical and horizontal guardrails interspersed to form a grid-like structure, effectively prevents construction workers, tools, or other objects from falling from the platform edge, significantly reducing the risk of fall accidents.

[0029] Preferably, the guardrail further includes a baffle, which is located at the bottom of the vertical guardrail and is fixedly connected to the vertical guardrail.

[0030] This structural design, with its alternating vertical and horizontal guardrails forming a grid, effectively intercepts larger objects. However, smaller tools, bolts, or other debris may slip through the gaps in the grid. Installing barriers at the bottom of the guardrail creates a continuous barrier that effectively prevents these small objects from falling into the area below, reducing the risk of workers or equipment being accidentally struck and improving the overall safety of the construction site.

[0031] Preferably, handrails are provided on both sides of the first ladder, the second ladder, and the third ladder.

[0032] With this structural design, the handrails on both sides of the ladder provide grip and support for construction workers during the climbing process, enhancing safety and comfort.

[0033] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0034] 1. This utility model provides a safety protection platform for a bridge-building machine, which sets the middle platform on the outside of the inverted U-shaped gantry, avoiding the restriction of the gantry structure on the movement of construction personnel, allowing construction personnel to move more freely on the platform, no longer restricted by the narrow space inside the gantry, and greatly improving the convenience of operation.

[0035] 2. This utility model provides a safety protection platform for a bridge-building machine. By setting an intermediate platform between the outer formwork truss platform and the bottom platform, construction workers do not need to climb directly from the bottom platform to the outer formwork truss platform. Instead, they can first climb to the intermediate platform and then climb to the outer formwork truss platform from the intermediate platform, avoiding the inconvenience of going up and down caused by traditional vertical cage ladders. The angles of the first and second ladders are designed to be 45°~60°, and the angle of the third ladder is 60°~70°. This gentler inclination angle significantly reduces the difficulty of climbing, making it easier for construction workers to move up and down, reducing physical exertion, improving work efficiency, and significantly reducing the safety hazards of climbing.

This utility model provides a safety protection platform for a bridge-building machine, which constructs a multi-layered working system by setting up a bottom platform, a middle platform, an outer formwork truss platform, and a top platform. These platforms are located at different heights of the bridge-building machine, facilitating construction personnel to carry out construction at different heights of the machine. Guardrails are installed on each platform, effectively preventing construction personnel from falling from heights due to slips or accidents in high-altitude working environments, significantly improving operational safety.

Detailed Implementation

[0044] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0045] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use.

[0046] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0047] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0048] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0050] Example 1

[0051] like Figure 1 , Figure 2 As shown, this embodiment provides a safety protection platform for a bridge-building machine, which can be used for cantilever bridge-building machines. The safety protection platform for the bridge-building machine includes:

[0052] The middle platform 1 is located at the bottom of the inverted U-shaped gantry 100 of the bridge-building machine, and is located on the outside of the inverted U-shaped gantry 100 (the side away from the concrete continuous beam). Setting the middle platform 1 on the outside of the inverted U-shaped gantry avoids the restriction of the gantry structure on the movement of construction personnel, allowing construction personnel to move more freely on the platform, no longer restricted by the narrow space inside the gantry, and greatly improving the convenience of operation.

[0053] Specifically, such as Figure 1 As shown, there can be two intermediate platforms 1, which are symmetrically arranged at the bottom of the inverted U-shaped gantry 100 of the bridge-building machine. For example, the intermediate platforms 1 can be configured as C-shaped structures, with the openings of the two intermediate platforms 1 facing each other. The intermediate platforms 1 can further be located at the front inverted U-shaped gantry (e.g., Figure 2 The rightmost inverted U-shaped gantry and the front-middle inverted U-shaped gantry (e.g.) Figure 2 Located on the outside of the inverted U-shaped gantry in the middle. The two symmetrical middle-level platforms 1 provide construction workers with a larger working space, facilitate their movement, and improve construction efficiency.

[0054] Bottom platform 2 is located at the bottom of the bridge building machine. Bottom platform 2 is connected to middle platform 1 through first ladder 21. The angle between first ladder 21 and the horizontal plane is 45°~60°.

[0055] Specifically, the underlying platform 2 can be located near the bottom template of the bridge-building machine, such as... Figure 1 As shown, there can be two first ladders 21, with each of the two first ladders 21 connecting to its corresponding intermediate platform 1. Figure 3 The angle α between the first ladder 21 and the horizontal plane is shown. ∠α can be 45°~60°, preferably 60°.

[0056] The outer formwork truss platform 3 is located above the middle platform 1. The middle platform 1 is connected to the outer formwork truss platform 3 via a second ladder 11, the angle between the second ladder 11 and the horizontal plane being 45°~60°. Specifically, the outer formwork truss platform 3 can be located near the top of the outer formwork of the bridge-building machine, and the angle between the second ladder 11 and the horizontal plane is preferably 60°.

[0057] The top platform 4 is located on top of the main load-bearing beam 200 of the bridge-building machine (or it can be set on top of the inverted U-shaped gantry 100 of the bridge-building machine). The top platform 4 is equipped with a third ladder 41, and the angle between the third ladder 41 and the horizontal plane is 60°~70°, preferably 70°. The top platform 4 is located on top of the main load-bearing beam 200 of the bridge-building machine, and the third ladder 41 extends downward from the top platform 4. The third ladder 41 can facilitate construction personnel to climb from the top of the concrete continuous beam to the top platform 4.

[0058] Furthermore, such as Figure 1 As shown, there can be two external formwork truss platforms 3, symmetrically arranged on both sides of the inverted U-shaped gantry 100 of the bridge-building machine. Specifically, the external formwork truss platforms 3 can be located between the front inverted U-shaped gantry and the middle front inverted U-shaped gantry. This dual-platform design provides more operating area for construction personnel, allowing multiple workers or different trades to work simultaneously, facilitating the movement of construction personnel, and improving construction efficiency.

[0059] Guardrail 5, such as Figure 1 , Figure 2 As shown, guardrails 5 are installed on the middle platform 1, the bottom platform 2, the outer formwork truss platform 3, and the top platform 4.

[0060] Furthermore, such as Figures 1-3 As shown, handrails 7 are installed on both sides of the first ladder 21, the second ladder 11, and the third ladder 41. The handrails 7 on both sides of the ladders provide gripping support for construction workers during the climbing process, enhancing safety and comfort.

[0061] The bridge-building machine safety protection platform provided in this embodiment, by setting an intermediate platform 1 between the outer formwork truss platform 3 and the bottom platform 2, allows construction workers to climb to the intermediate platform 1 first and then to the outer formwork truss platform 3 instead of directly climbing from the bottom platform 2 to the outer formwork truss platform 3. This avoids the inconvenience of going up and down caused by traditional vertical cage ladders. The angles of the first ladder 21 and the second ladder 11 are designed to be 45°~60°, and the angle of the third ladder 41 is 60°~70°. This gentler inclination angle significantly reduces the difficulty of climbing, making it easier for construction workers to move up and down, reducing physical exertion, improving work efficiency, and significantly reducing the safety hazards of climbing.

[0062] The bridge-building machine safety protection platform provided in this embodiment constructs a multi-layered, three-dimensional working system by setting up a bottom platform 2, a middle platform 1, an outer formwork truss platform 3, and a top platform 4. These platforms are located at different heights of the bridge-building machine, facilitating construction personnel to carry out work at different heights of the bridge-building machine.

[0063] The bridge-building machine safety protection platform provided in this embodiment is equipped with guardrails 5 on each platform, which effectively prevents construction workers from falling from heights due to slips or accidents in high-altitude working environments, and significantly improves operational safety.

[0064] Example 2

[0065] Based on Embodiment 1, the bridge-building machine safety protection platform provided in this embodiment also includes a bottom support platform 6. The bottom support platform 6 is installed at the lower part of the bottom platform 2. For example, the bottom support platform 6 can be attached to the bottom beam of the bridge-building machine, and the bottom support platform 6 can completely cover the bridge-building machine. Figure 1 , Figure 2 As shown, during construction, materials or debris may fall from above. The bottom support platform 6 is located below the bottom platform 2 and can effectively prevent these objects from falling. The bottom support platform 6 completely covers the bridge-building machine, meaning the bridge-building machine falls entirely within the orthographic projection of the bottom support platform 6, which can effectively protect personnel and equipment below from the impact of falling objects and ensure the safety of the construction site. Specifically, the bottom support platform 6 can be a rectangular structure.

[0066] Furthermore, such as Figure 5 As shown, the bottom support platform 6 includes a base plate 61 and side walls 62. Side walls 62 are installed along the edges of the base plate 61. For example, the base plate 61 may be a rectangular plate structure. With side walls 62 on all four sides of the base plate 61, the bottom support platform 6 is a box-shaped structure with its opening facing upwards. The bottom support platform 6, with its base plate 61 and side walls 62 forming an upward-opening box-shaped structure, creates a container-like space capable of accommodating objects falling from above, preventing them from falling directly to the area below, thereby protecting construction personnel and equipment from injury.

[0067] Furthermore, such as Figure 5 As shown, several reinforcing ribs 621 are installed on the side wall 62. The reinforcing ribs 621 can be installed as follows: Figure 5 The stiffeners 621 are spaced apart on the outer side of the sidewall 62, and their extension direction can be perpendicular to the base plate 61. With this structural arrangement, the addition of the stiffeners 621 enables the sidewall 62 to effectively resist bending or torsional deformation when subjected to large loads, ensuring the stability of the structure.

[0068] Example 3

[0069] Based on Example 1, the bridge-building machine safety protection platform provided in this example, such as Figure 4 As shown, the guardrail 5 includes several vertical bars 51 and several horizontal bars 52, which are staggered. Specifically, for example, the vertical bars 51 and horizontal bars 52 can be arranged vertically. The staggered arrangement of the vertical bars 51 and horizontal bars 52 forms a grid structure, which can effectively prevent construction workers, tools or other objects from falling from the edge of the platform, significantly reducing the risk of fall accidents.

[0070] Furthermore, such as Figure 4 As shown, the guardrail 5 also includes a baffle 53, which is located at the bottom of the vertical bars 51 and is fixedly connected to the vertical bars 51. With this structural arrangement, while the staggered grid structure of the vertical bars 51 and horizontal bars 52 can effectively intercept larger objects, smaller tools, bolts, or other debris may slip through the gaps in the grid. By placing the baffle 53 at the bottom of the guardrail 5, a continuous barrier is formed, effectively preventing these small objects from falling into the area below, reducing the risk of construction workers or equipment being accidentally hit, and improving the overall safety of the construction site.

[0071] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
