Description

Technical Field

[0001] This utility model relates to the field of engineering construction operation technology, specifically to a bridge anti-collision guardrail operation platform. Background Technology

[0002] During the construction of bridge concrete crash barriers, in order to ensure the appearance quality of the concrete, it is necessary to seal the tie bolt holes left after the construction of the crash barriers, and at the same time repair the appearance defects caused during the concrete pouring process. In actual construction, the inner side of the crash barriers has a working surface, which makes construction convenient, while the outer side of the crash barriers is more difficult to construct. Therefore, a bridge crash barrier working platform is used during construction.

[0003] The existing work platform mainly consists of a frame that hangs on the guardrail. The frame is mainly composed of an inner climbing frame and an outer climbing frame that together form a figure eight. The inner climbing frame and the outer climbing frame are placed on the inner and outer sides of the guardrail, respectively. The length of the outer climbing frame is greater than that of the inner climbing frame. The lower end of the outer climbing frame extends to the bottom of the guardrail and is equipped with a work platform for people to stand and work.

[0004] After the work platform is installed, the construction workers on the bridge ground need to climb from the bottom of the inner climbing frame to the top, and then descend from the top of the outer climbing frame to the work platform. However, when climbing to the top of the inner climbing ladder, the workers are already at the highest point of the work platform, and facing the high-altitude scene outside the bridge, they will experience significant psychological pressure, which may cause them to feel panicked or trembling. When transferring from the inner climbing frame to the outer climbing frame, the workers need to make turning and crouching movements to descend from the outer climbing frame. When making these movements, there is not enough support for their hands, and the psychological pressure makes the movement difficult, which will greatly affect the efficiency and safety of the construction. Utility Model Content

[0005] This utility model provides a bridge anti-collision guardrail operation platform, which can overcome some or all the defects of the prior art.

[0006] According to the present invention, a bridge anti-collision guardrail working platform includes a platform body; the platform body includes a truss arranged parallel to the upper surface of the guardrail along the width direction of the guardrail; an inner climbing frame and an outer climbing frame are provided at the lower surface of the truss, the inner climbing frame and the outer climbing frame being close to the inner and outer sides of the guardrail respectively; a working platform is provided at the lower end of the outer climbing frame.

[0007] The upper end face of the truss is equipped with a handrail that runs along the length of the truss. The handrail is used by construction workers to grab onto when moving from the inner climbing truss to the outer climbing truss.

[0008] The handrail of this utility model can be used to support construction workers when they move from the inner scaffold to the outer scaffold, which can help stabilize their emotions and increase their sense of security under psychological pressure, while ensuring safety during the transfer and preventing falls.

[0009] Preferably, the truss includes two long poles spaced apart along the length of the railing; one end of the two long poles is connected to a short pole; the handrail frame includes a bent pole; the bent pole is bent and connected to the long pole; the two ends of the bent pole are respectively connected to the two ends of the long pole, and together they form a triangle.

[0010] In this invention, the triangular arrangement of the bent rod and the long rod enhances the stability of the handrail, thereby increasing safety during personnel transfer. Furthermore, the bent rod is lower towards both ends, allowing construction workers to grasp different heights of the bent rod when moving up and down the inner and outer climbing frames, making movement more convenient.

[0011] Preferably, the handrail also includes a reinforcing bar; one end of the reinforcing bar is vertically connected to the long bar, and the other end is connected to the bending point of the curved bar.

[0012] In this invention, the reinforcement rods divide the triangle formed by the curved rods and the long rods into two, thereby further improving stability. The vertical arrangement of the reinforcement rods ensures that construction workers can still grip the frame when moving up and down the inner and outer climbing frames. The curved rods and reinforcement rods allow construction workers to grip the appropriate position as needed.

[0013] Preferably, one end of the inner climbing frame is connected to two long poles, and the outer side of the inner climbing frame is provided with scissor braces connected to the long poles.

[0014] In this invention, the scissor bracing creates a triangle between the long rod, one side of the inner climbing frame, and the scissor bracing, thereby improving the stability of the inner climbing frame.

[0015] Preferably, the external climbing scaffold is provided with two spaced-apart stabilizing frames; each stabilizing frame includes a vertical rod and a horizontal rod; one end of the vertical rod is connected to a long rod, and the other end is connected to the working platform; both ends of the horizontal rod are connected to the vertical rod and the outer side of the external climbing scaffold, respectively.

[0016] In this invention, the stabilizing frame allows both sides of the work platform to be connected, thereby improving the stability of the work platform and ensuring the safety of personnel working on the work platform.

[0017] Preferably, a connecting rod is vertically connected to the middle of the two long rods; the connecting rod is provided with a plurality of spaced first pulleys.

[0018] In this invention, the first pulley allows the entire platform to move more easily by contacting the upper surface of the guardrail, thereby improving the efficiency of platform movement.

[0019] Preferably, both the inner and outer climbing frames are equipped with multiple second pulleys on the side facing the guardrail; both the first and second pulleys are in contact with the guardrail.

[0020] In this invention, the combination of the first and second pulleys allows the entire platform to move easily along the guardrail. When movement is required, workers can stand inside the guardrail and push the platform, or push the concrete surface of the crash barrier on the platform to move it.

[0021] Preferably, a first lifting ring is provided at the end of the long pole away from the short pole; a second lifting ring is provided at the bend of the curved pole.

[0022] In this invention, the first lifting ring allows for the hanging of counterweights as needed, ensuring the stability of the platform; the second lifting ring allows for the connection of safety belts worn by construction workers, thus ensuring their safety. Attached Figure Description

[0031] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0032] Example 1

[0033] like Figure 1-8 As shown, this embodiment provides a bridge crash barrier 101 working platform, which includes a platform body 100; the platform body 100 includes a truss 110 arranged parallel to the upper surface of the guardrail 101 along the width direction of the guardrail 101; an inner climbing frame 120 and an outer climbing frame 130 are provided at the lower surface of the truss 110, the inner climbing frame 120 and the outer climbing frame 130 being close to the inner and outer sides of the guardrail 101 respectively; a working platform 140 is provided at the lower end of the outer climbing frame 130;

[0034] A handrail 160 is provided on the upper end face of the truss 110 along the length of the truss 110. The handrail 160 is used for construction workers to grab when moving from the inner climbing frame 120 to the outer climbing frame 130.

[0035] The handrail 160 in this embodiment provides support for construction workers as they move from the inner climbing scaffold 120 to the outer climbing scaffold 130. This helps stabilize their emotions and increase their sense of security under psychological pressure, while also ensuring safety during the transfer and preventing falls. When workers are working, they can climb from the lower end to the upper end of the inner climbing scaffold 120 and grab the curved bar 161 of the handrail 160 as they approach the top. They can grab the curved bar 161 at different heights as they move to different positions. When workers move from the upper end of the inner climbing scaffold 120 to the upper end of the outer climbing scaffold 130, they can hold onto the handrail 160 throughout the entire transfer process. Even when looking out at the high altitude outside the bridge, they will realize that holding onto the handrail 160 can prevent them from falling, reducing the possibility of a fall. This greatly enhances their sense of security, reduces panic and shaking caused by fear and psychological pressure, and ensures stable movement while maintaining construction efficiency and safety.

[0036] In this embodiment, the truss 110 includes two long poles 611 spaced apart along the length of the guardrail 101; one end of the two long poles 611 is connected to a short pole 612; the handrail frame 160 includes a bent pole 161; the bent pole 161 is bent and connected to the long pole 611; the two ends of the bent pole 161 are respectively connected to the two ends of the long pole 611, and together they form a triangle.

[0037] The triangular arrangement of the bent rod 161 and the long rod 611 in this embodiment enhances the stability of the handrail 160, thereby increasing safety during personnel movement. Furthermore, the bent rod 161 is lower towards both ends, allowing workers to grasp different heights of the bent rod 161 when moving up and down the inner and outer climbing frames 120 and 130, making movement easier. Both the inner and outer climbing frames 120 and 130 are common ladder structures composed of horizontal and vertical rods; the outer climbing frame 130 is longer than the inner climbing frame 120. In this embodiment, the inner climbing frame 120 has four... The outer climbing frame 130 has 4-10 horizontal bars, i.e., 4-10 steps. For example, when climbing the inner climbing frame 120, when standing on the first step at the bottom of the inner climbing frame 120, one can grab the lowest point of the curved bar 161. As one climbs higher, one can grab the highest point of the curved bar 161. When moving to the outer climbing frame 130 by bending, squatting, or changing direction, one can still grab the corresponding position of the handrail 160. Similarly, when moving from the highest position of the outer climbing frame 130 to the work platform 140, one can grab the corresponding position of the handrail 160.

[0038] In this embodiment, the handrail frame 160 also includes a reinforcing rod 162; one end of the reinforcing rod 162 is vertically connected to the long rod 611, and the other end is connected to the bending point of the bent rod 161.

[0039] By setting the reinforcing rod 162 in this embodiment, the triangle formed by the bent rod 161 and the long rod 611 is divided into two, thereby further improving stability. Furthermore, the vertical setting of the reinforcing rod 162 allows construction workers to still grab it when the inner climbing frame 120 and the outer climbing frame 130 move up and down. The bent rod 161 and the reinforcing rod 162 enable construction workers to grab the appropriate position according to their needs.

[0040] In this embodiment, one end of the inner climbing frame 120 is connected to two long rods 611, and the outer side of the inner climbing frame 120 is provided with scissor braces 121 connected to the long rods 611.

[0041] By setting the scissor brace 121 in this embodiment, a triangle is formed between the long rod 611, one side of the inner climbing frame 120 and the scissor brace 121, thereby improving the stability of the inner climbing frame 120.

[0042] In this embodiment, two spaced-apart stabilizing frames 150 are provided at the outer climbing frame 130; the stabilizing frame 150 includes a vertical rod 152 and a horizontal rod 151; one end of the vertical rod 152 is connected to the long rod 611, and the other end is connected to the working platform 140; the two ends of the horizontal rod 151 are respectively connected to the vertical rod 152 and the outer side of the outer climbing frame 130.

[0043] The stabilizing frame 150 in this embodiment allows both sides of the work platform 140 to be connected, thereby improving the stability of the work platform 140 and ensuring the safety of personnel working on the work platform 140. Since the outer climbing frame 130 is longer than the inner climbing frame 120, it becomes increasingly difficult to grasp the handrail 160 as one gets closer to the work platform 140. Therefore, when personnel are facing the guardrail 101 and moving down, they can grasp the outer climbing frame 130 with both hands; when facing the outside of the bridge and moving down with their back to the guardrail 101, they can grasp the vertical bars 152 of the stabilizing frame 150 with both hands. Multiple horizontal bars 151 can be installed to enclose the gaps between each set of stabilizing frames 150 and between the stabilizing frame 150 and the outer climbing frame 130, preventing personnel from falling off the work platform 140. The work platform 140 consists of a grid structure composed of multiple horizontal and vertical bars for personnel to stand on.

[0044] In this embodiment, a connecting rod 614 is vertically connected to the middle of the two long rods 611; the connecting rod 614 is provided with a plurality of spaced first pulleys 115.

[0045] By configuring the first pulley 115 in this embodiment, the entire platform can be moved relatively easily through the contact between the first pulley 115 and the upper surface of the guardrail 101, thereby improving the efficiency of platform movement; wherein, see Figure 6 As can be seen, the connecting rod 614, the long rod 611, and the short rod 612 form a rectangular entrance / exit 613. This entrance / exit 613 is located directly above the outer climbing scaffold 130. Through this entrance / exit 613, personnel can be surrounded by the entrance / exit 613 during the transfer from the inner climbing scaffold 120 to the outer climbing scaffold 130, providing more grab points. At the same time, this entrance / exit 613 can also give construction workers a certain sense of security and reduce fear and other stress.

[0046] In this embodiment, both the inner climbing frame 120 and the outer climbing frame 130 are provided with a plurality of second pulleys 122 on the side facing the guardrail 101; the first pulley 115 and the second pulley 122 are both in contact with the guardrail 101.

[0047] The combination of the first pulley 115 and the second pulley 122 in this embodiment allows the entire platform to move easily at the guardrail 101. When movement is required, workers can stand inside the guardrail 101 to push the platform, or push the concrete surface of the anti-collision guardrail 101 at the platform to move it.

[0048] In this embodiment, a first lifting ring 116 is provided at the end of the long rod 611 away from the short rod 612; a second lifting ring 163 is provided at the bend of the bent rod 161.

[0049] The first lifting ring 116 in this embodiment allows for the hanging of counterweights as needed, ensuring the stability of the platform; the second lifting ring 163 allows for the connection of safety belts worn by construction workers, thereby ensuring the safety of construction workers.

[0050] In this embodiment, all the rods are hollow square rods. Except for the first pulley 115, the second pulley 122, the first lifting ring 116 and the second lifting ring 163, they are all made of hollow square rods with a wall thickness of 3mm and connected by full welding process.

[0051] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

[0052] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
