Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a safety hanging basket for bridge construction. Background Art

[0002] In the field of contemporary bridge construction, with the vigorous development of social economy and the continuous increase in traffic demand, the construction projects of long-span bridges are becoming more and more common. In order to meet the increasingly stringent engineering quality standards, urgent construction progress requirements and extremely high safety regulations, bridge construction technology is undergoing continuous innovation and progress.

[0003] In bridge construction projects, drainage pipe installation is a key link in ensuring the durability and usability of bridge structures. With the continuous expansion of the scale of bridge construction and the increasing requirements for drainage systems,

[0004] A hanging basket for bridge construction is disclosed in Chinese patent publication number CN222100655U. The hanging basket for bridge construction is driven by a driving motor to drive a wire drum to rotate, and the wire drum reels and unwinds the wire rope. When the wire drum reels the wire rope, the hanging basket is pulled upward, and when the wire drum unwinds the wire rope, the hanging basket is moved downward. Therefore, the material inside the hanging basket can be hoisted and moved to different heights of the bridge.

[0005] However, compared with the existing technologies in related fields, construction workers need to climb when entering the hanging basket. This method is in a high-altitude environment, which not only increases the physical burden of construction workers, but also prolongs the overall construction time, reducing the time and energy invested in key tasks such as drainage pipe installation, affecting the construction progress. At the same time, workers are prone to slip and fall due to physical fatigue, careless operation, etc., resulting in serious safety accidents and threatening the lives of construction workers. In the process of transferring tools, tools may easily fall from a height due to operating errors, mismatch of transfer tools, etc., which may not only injure construction workers below, but also damage equipment at the construction site, increasing the risk of safety accidents and construction costs. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background technology, and provide a safety hanging basket for bridge construction.

[0007] The purpose of the utility model is achieved through the following technical solutions: a safe hanging basket for bridge construction, including a mobile vehicle, a mobile frame is provided on the top of the mobile vehicle for transverse sliding, a conveying assembly is provided on the end of the mobile frame away from the mobile vehicle for longitudinal sliding, a hanging basket body is fixedly installed on the bottom of the conveying assembly, a accommodating frame is provided on the side of the conveying assembly close to the mobile vehicle, the conveying assembly is used to control the up and down movement of the accommodating frame, and supporting assemblies are hinged at the four corners of the top of the accommodating frame. When the accommodating frame transports the pipeline, multiple supporting assemblies swing downward under the influence of gravity, thereby cooperating with each other to form a V shape, and the mobile vehicle is provided with a first driving assembly for controlling the transverse sliding of the mobile frame and a second driving assembly for controlling the longitudinal sliding of the conveying assembly.

[0008] Preferably, the conveying assembly includes a fixed frame, and sprocket shafts are fixedly installed on the upper and lower sides of the fixed frame, and the outer surfaces of the two sprocket shafts are meshedly connected with the chain conveyor belt.

[0009] Preferably, the containing frame is fixedly mounted on the chain conveyor belt, and a first motor for controlling the rotation of one of the sprocket shafts is fixedly mounted on the side of the fixing frame.

[0010] Preferably, hinge grooves are provided at the four corners of the top of the accommodating frame, and the supporting assembly includes a sleeve hinged to the hinge groove via an elastic rotating shaft, and a supporting plate is fixedly provided on the outer surface of the sleeve.

[0011] Preferably, an anti-slip layer is fixedly provided on the outer surface of the supporting plate.

[0012] Preferably, the first drive assembly includes a second motor and a differential fixedly mounted on the mobile vehicle, the output end of the second motor is connected to the input end of the differential, a gear is fixedly mounted on the output end of the differential, and a rack meshing with the gear is fixedly mounted on one side of the mobile frame close to the gear.

[0013] Preferably, the second driving assembly includes a winch fixedly mounted on the mobile vehicle, the winch is provided with a lifting rope, a fixing block is fixedly mounted on the top of the fixing frame, and one end of the lifting rope is connected to the fixing block.

[0015] Beneficial effects:

[0016] The safety hanging basket for bridge construction is provided with a conveying component, a receiving frame and a supporting component. On the one hand, the conveying component allows the workers to stand directly on the receiving frame on the bridge deck, and then control the receiving frame to descend into the inside of the hanging basket body through the conveyor belt. Compared with traditional climbing methods, it greatly reduces the risk of falling caused by slipping and other reasons during the high-altitude movement of workers, and provides a safe and stable channel for workers to enter the hanging basket body, further ensuring the safety of personnel. On the other hand, compared with the traditional tool delivery process, the tools may fall from a height due to improper delivery and other reasons, posing a safety threat to the construction personnel or equipment below. The tools are transported on a relatively closed and stable receiving frame by transmitting the tools through the receiving frame, which greatly reduces the risk of the tools falling and ensures the safety of the construction site. On the other hand, the supporting component that can be deformed into a V shape on the receiving frame can automatically adjust its shape according to pipes of different diameters. This means that no matter what specifications of drainage pipes are encountered, they can be stably placed on the receiving frame, avoiding rolling and sliding during transportation or installation due to unstable placement of the pipes, thereby ensuring the safety of the construction process.

[0028] Additional aspects and advantages of the present invention will be further described below in conjunction with the accompanying drawings, and some will become apparent from the following description or be learned through practice of the present invention.

[0029] like Figures 1 to 8 As shown, a safety hanging basket for bridge construction comprises a mobile vehicle 1, a mobile frame 2 is provided on the top of the mobile vehicle 1 for transverse sliding, a conveying assembly 3 is provided on the end of the mobile frame 2 away from the mobile vehicle 1 for longitudinal sliding, a hanging basket body 4 is fixedly installed on the bottom of the conveying assembly 3, a placing table 101 is fixedly installed on the side of the mobile vehicle 1 away from the hanging basket body 4, a counterweight 102 is placed on the placing table 101, and the counterweight 102 is arranged, and the stability of the mobile vehicle 1 during movement can be further improved by using the arranged counterweight 102, a receiving frame 5 is provided on the side of the conveying assembly 3 close to the mobile vehicle 1, the conveying assembly 3 is used to control the up and down movement of the receiving frame 5, and the four corners of the top of the receiving frame 5 are hinged with supporting assemblies 6, when the receiving frame 5 transports the pipeline, a plurality of supporting assemblies 6 swing downward under the influence of gravity, thereby cooperating with each other to form a V-shape, and a first driving assembly 7 for controlling the transverse sliding of the mobile frame 2 and a second driving assembly 8 for controlling the longitudinal sliding of the conveying assembly 3 are provided on the mobile vehicle 1.

[0030] like Figure 5 and Figure 6As shown, the conveying assembly 3 includes a fixed frame 301, sprocket shafts 302 are fixedly installed on the upper and lower sides of the fixed frame 301, the outer surfaces of the two sprocket shafts 302 are meshed and connected with chain conveyor belts 303, the receiving frame 5 is fixedly installed on the chain conveyor belt 303, and the side of the fixed frame 301 is fixedly installed with a first motor 3011 for controlling the rotation of one of the sprocket shafts 302, as shown in FIG. Figures 2 to 4 As shown, after the receiving frame 5 moves to the top, the staff can stand on the receiving frame 5, and then control one of the sprocket shafts 302 to rotate in the opposite direction through the first motor 3011, so that the chain conveyor belt 303 controls the receiving frame 5 to move downward, ensuring that the staff can safely enter the hanging basket body 4, greatly reducing the risk of falling due to slipping and the like during high-altitude movement of the staff. When the staff enters the hanging basket body 4, the receiving frame 5 can be controlled to move up and down, thereby facilitating the transportation of tools, greatly reducing the risk of tools falling, and ensuring the safety of the construction site.

[0031] like Figure 7 and Figure 8 As shown, hinge grooves 501 are provided at the four corners of the top of the accommodating frame 5, and the supporting assembly 6 includes a sleeve 601 hinged to the hinge groove 501 through an elastic rotating shaft, and a supporting plate 602 is fixedly provided on the outer surface of the sleeve 601, and an anti-skid layer is fixedly provided on the outer surface of the supporting plate 602.

Figures 3 to 6As shown, during the construction of the bridge, the mobile vehicle 1 is controlled to reach the specified position, and then the power is transmitted to the differential 702 through the second motor 701, and then the gear 703 is controlled by the differential 702, so that the movable frame 2 is controlled to extend out of the bridge deck through the meshing connection between the gear 703 and the rack 704. When the entire project is completed, the staff can stand on the accommodating frame 5, and then control one of the sprocket shafts 302 to rotate through the first motor 3011, so that the chain conveyor belt 303 controls the accommodating frame 5 to move upward, so that the staff can return to the bridge deck safely again. At this time, through the cooperation between the winch 801 and the suspension rope 802, the fixed frame 301 is controlled to slide upward, so that the hanging basket body 4 reaches the bridge deck, and then the power is transmitted to the differential 702 through the second motor 701, and then the gear 703 is controlled by the differential 702, so that the movable frame 2 is controlled to be retracted to the bridge deck through the meshing connection between the gear 703 and the rack 704.

[0034] To sum up, the specific effects are as follows:

[0035] Convenient and safe moving method: The conveying assembly 3 allows the staff to stand directly on the receiving frame 5 on the bridge deck, and then control the receiving frame 5 to descend into the hanging basket body 4 through the conveyor belt. Compared with traditional climbing methods, it greatly reduces the risk of falling due to slipping and other reasons during the high-altitude movement of the staff, and provides a safe and stable passage for the staff to enter the hanging basket body 4, further ensuring the safety of the staff.

[0036] Save manpower and time: Workers no longer need to climb or other physically demanding ways to enter the hanging basket body 4, but can easily reach it with the help of the conveying assembly 3, saving a lot of manpower and time costs. This allows construction workers to devote more energy to core work such as drainage pipe installation, improving overall construction efficiency.

[0037] Reduce the risk of tool falling: In the traditional tool delivery process, tools may fall from a height due to improper delivery and other reasons, posing a safety threat to construction workers or equipment below. By transmitting tools through the receiving rack 5, the tools are transported on the relatively closed and stable receiving rack 5, which greatly reduces the risk of tool falling and ensures the safety of the construction site.

[0038] Adaptable to various pipe diameters: The support component 6 that can be deformed into a V shape arranged on the receiving frame 5 can automatically adjust its shape according to pipe parts of different diameters. This means that no matter what specifications of the drainage pipe are encountered, it can be stably placed on the receiving frame 5, avoiding rolling, sliding, etc. during transportation or installation due to unstable placement of the pipe, thereby ensuring the safety of the construction process.

[0039] The working process is as follows:

[0040] S1: Figure 1 and Figure 2 As shown, during the construction of the bridge, the mobile vehicle 1 is controlled to reach the designated position, and then the power is transmitted to the differential 702 through the second motor 701, and then the gear 703 is controlled by the differential 702, so that the mobile frame 2 is controlled to extend out of the bridge deck through the meshing connection between the gear 703 and the rack 704;

[0041] S2: Figure 1 and Figure 2 As shown, after the mobile frame 2 extends out of the bridge deck, the fixed frame 301 is controlled to slide downward through the cooperation between the winch 801 and the suspension rope 802, so that the hanging basket body 4 reaches the side or bottom of the bridge;

[0042] S3: Figures 2 to 4 As shown, when the hanging basket body 4 reaches the side or bottom of the bridge, the first motor 3011 controls one of the sprocket shafts 302 to rotate, so that the chain conveyor belt 303 controls the receiving frame 5 to move upward;

[0043] S4: Figures 2 to 6 As shown, when the accommodating frame 5 moves to the top, the staff can stand on the accommodating frame 5, and then control one of the sprocket shafts 302 to rotate in the opposite direction through the first motor 3011, so that the chain conveyor belt 303 controls the accommodating frame 5 to move downward, ensuring that the staff can safely enter the interior of the hanging basket body 4, greatly reducing the risk of falling due to missteps during the high-altitude movement of the staff;

[0044] S5: Figures 2 to 6 As shown, when the worker enters the interior of the hanging basket body 4, the steps S3 and S4 can be repeated to control the accommodating frame 5 to move up and down, thereby facilitating the transportation of tools, greatly reducing the risk of tools falling, and ensuring the safety of the construction site;

[0045] S6: Figure 7 and Figure 8As shown, when the receiving rack 5 carries the pipe object, the supporting plate 602 swings downward under the influence of gravity, thereby cooperating with each other to form a V shape, thereby effectively ensuring the stability of the pipe object when it is transported downward, avoiding rolling or sliding during transportation or installation due to unstable placement of the pipe, and ensuring the safety of the construction process;

[0046] S7: When the construction of a single point is completed, the construction position can be adjusted by moving the mobile vehicle 1. At the same time, when the entire project is completed, the staff can stand on the receiving frame 5, and then control one of the sprocket shafts 302 to rotate through the first motor 3011, so that the chain conveyor belt 303 controls the receiving frame 5 to move upward, so that the staff can return to the bridge deck safely again. At this time, through the cooperation between the winch 801 and the suspension rope 802, the fixed frame 301 is controlled to slide upward, so that the hanging basket body 4 reaches the bridge deck, and then the power is transmitted to the differential 702 through the second motor 701, and then the gear 703 is controlled by the differential 702, so that the movable frame 2 is controlled to be retracted to the bridge deck through the meshing connection between the gear 703 and the rack 704.

[0047] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
