Description

Technical Field

[0001] The utility model relates to the technical field of underwater temporary platform structure engineering, in particular to a slag clearing and dredging device during flood season. Background Art

[0002] During water-related construction operations, such as those across rivers and near waterways, temporary platforms are often required. These platforms' columns inevitably protrude into the riverbed, causing floating debris to accumulate and become trapped on them. Especially during flood season, when upstream debris increases exponentially, these objects can become entangled and trapped in the platform columns, leading to accumulation beneath them. This slows the flow of water and reduces water flow, posing a significant threat to the platform's safety and stability.

[0003] In order to reduce or avoid the risk of collapse of the temporary work platform, on the one hand, the structure of the temporary work platform should be modified. While ensuring the safety and stability of the structure, the structure of the temporary work platform should be as simple as possible, and the space under the platform should be as open as possible to facilitate the smooth passage of drifting objects in the river through the temporary work platform. However, on the other hand, since the columns of the work platform are always there, it is inevitable that drifting objects will accumulate and entangle on the columns. Therefore, how to clear the debris and dredge the area under the temporary work platform to keep the water flow unobstructed and ensure the structural safety of the temporary work platform is also a direction that needs to be considered.

[0004] Existing slag removal and dredging methods mainly include manual or mechanical equipment, but there are the following problems:

[0005] First, manual slag removal is limited in capacity and cannot remove large amounts of accumulated debris. Moreover, during the flood season, due to the large amount of floating debris and turbulent water flow, it is easy for human control of the slag removal equipment to occur, threatening the safety of the slag removal workers.

[0006] Secondly, when mechanical equipment is used for slag removal, excavators are primarily used. However, due to the lack of dedicated slag removal equipment, the excavator bucket is impermeable and has high resistance, resulting in poor slag removal efficiency. Therefore, designing specialized structural equipment suitable for slag removal during flood season is a major challenge facing technicians working on temporary underwater platform structures.

[0007] The same situation also occurs in the application of some old bridges. Due to the limitations of the technology at the time of bridge construction, there are a large number of piers during the design and construction of the bridge. Many piers are located in key water-passing positions. During the flood season, the upstream is affected by floods, and floating objects will accumulate and entangle on the piers, which not only seriously affects the water flow of the bridge, but also threatens the safety of the piers and bridge application. The floating objects also need to be cleaned up. Utility Model Content

[0008] At least one of the purposes of the invention of the utility model is to provide a slag cleaning and dredging device during the flood season, in view of the lack of special structural equipment for salvaging floating objects during the flood season in the prior art. The slag cleaning and dredging device can capture floating objects in the river through a salvage part and be installed on mechanical equipment through a connecting part, so that the slag cleaning and dredging device has a greater slag cleaning capacity.

[0009] In order to achieve the above-mentioned objectives, the technical solutions adopted by the present invention include the following aspects.

[0010] A slag clearing and dredging device during flood season includes a main body and a connecting part connected to the main body, wherein the connecting part is used to be connected to mechanical equipment. The main body is also provided with a salvage part, and a salvage groove is formed between the salvage part and the main body, and the opening of the salvage groove faces one side of the connecting part.

[0011] This technical solution is to provide a salvage part on the main body, and form a salvage groove between the salvage part and the main body, so that during the slag cleaning and dredging process, floating objects can be accommodated in the salvage groove to complete the fishing. At the same time, a connecting part is provided to fix the slag cleaning and dredging device on mechanical equipment (excavator or other lifting equipment). After the connecting part is connected to the mechanical equipment, slag cleaning and dredging are carried out by fishing back and forth in the river channel.

[0012] The opening of the salvage trough faces one side of the connecting part, so that during the catching and ascending process of the mechanical equipment, the floating objects can be engaged on the salvage part and will not fall off, thus completing the slag removal smoothly.

[0013] As a preferred solution of the present invention, the main body is made of a steel pipe, the connecting portion is fixedly connected to one end of the steel pipe, and the salvaging portion is arranged at the other end of the steel pipe.

[0014] The main body structure is made of steel pipes. The steel pipe structure as the main body is not only light in weight and improves the fishing capacity, but also the steel pipe has a large cross-sectional moment of inertia and high structural strength.

[0015] Furthermore, the steel pipe is a round steel pipe or a square steel pipe.

[0016] Steel columns or other steel sections (such as channel steel, flat steel) can also be used as the main body, or a columnar steel structure formed by welding steel bars can be used as the main body.

[0017] As a preferred solution of the present invention, the salvage portion is a plurality of U-shaped steel bars welded to the end of the steel pipe, and the plurality of U-shaped steel bars are arranged along a circle around the outer periphery of the steel pipe.

[0018] The U-shaped steel bar includes a first side bar and a second side bar on both sides, and a horizontal bar connected between the first side bar and the second side bar. The first side bar or the second side bar of the U-shaped steel bar is welded to the steel pipe, and the first side bar or the second side bar is arranged parallel to the axis of the steel pipe; the U-shaped opening of the U-shaped steel bar serves as a salvage groove, and the slag cleaning and dredging device is used to accommodate and clamp floating objects during the process of salvaging floating objects.

[0019] As a preferred solution of the present invention, one end of each of the plurality of U-shaped steel bars is a sharp structure.

[0020] The first side bar or the second side bar of the U-shaped steel bar is welded to the steel pipe, and the remaining first side bar or the second side bar adopts a sharp structure. The sharp structure can quickly penetrate into the floating object, avoiding the inconvenience of the slag cleaning and dredging device in fixing the floating object during the salvage process. The setting of the sharp structure can improve the salvage efficiency.

[0021] Furthermore, the number of the U-shaped steel bars is 6, and the 6 U-shaped steel bars are evenly welded on the outer wall of the steel pipe.

[0022] Other solutions include using L-shaped steel bars welded to the main body as a salvage portion, or using V-shaped steel bars welded to the main body to salvage floating objects.

[0023] As a preferred solution of the present invention, the connecting part includes a first steel plate and a second steel plate welded to the steel pipe, and the sides of the first steel plate and the second steel plate are welded to the outer wall of the steel pipe, so that the plate surface direction of the first steel plate and the second steel plate is consistent with the axis of the steel pipe.

[0024] Furthermore, the first steel plate and the second steel plate are arranged in a vertical state, so that the angle between the plate surfaces of the first steel plate and the second steel plate is 90 degrees.

[0025] By welding two steel plates on a steel pipe, the two steel plates are arranged vertically at different positions on the outer wall of the steel pipe, so that when the slag cleaning and dredging device is connected to the salvage machinery and equipment, it can be welded to the first steel plate and the second steel plate, thereby improving the connection strength between the slag cleaning and dredging device and the salvage machinery and equipment, and ensuring normal and safe salvage of floating objects.

[0026] Other solutions also include setting threaded holes on the first steel plate and the second steel plate, and connecting the slag cleaning and dredging device to the salvage machinery and equipment in a detachable manner through the threaded holes. When floating objects need to be salvaged during the flood season, the slag cleaning and dredging device is installed on the machinery and equipment. When the river channel is dry, the slag cleaning and dredging device is dismantled and placed, and the machinery and equipment is used for other purposes.

[0027] As a preferred solution of the present invention, water holes are provided on the steel pipe.

[0028] By setting water-permeable holes on the steel pipe, water can pass through the water-permeable holes when the slag cleaning and dredging device is used to salvage floating objects, reducing the resistance of the slag cleaning and dredging device operating in water, reducing the working energy consumption of mechanical equipment, and improving operating efficiency.

[0029] Furthermore, the water-permeable holes are evenly or unevenly opened on the steel pipe.

[0030] As a preferred embodiment of the present invention, the steel pipe is provided with a reinforcing strip along the outer wall thereof, thereby improving the structural strength of the slag cleaning and dredging device and ensuring that the slag cleaning and dredging device can function normally and safely to salvage floating objects.

[0031] Furthermore, the reinforcement strips include longitudinal reinforcement strips arranged along the axis direction of the steel pipe, and transverse reinforcement strips, and the transverse reinforcement strips are arranged in a direction perpendicular to the axis direction of the steel pipe.

[0032] As a preferred solution of the present invention, a cross reinforcement bar is provided at the end of the steel pipe, and the cross reinforcement bar is used to support the inner cavity of the steel pipe.

[0033] Providing a cross reinforcement bar to support the inner cavity of the steel pipe can further improve the structural strength of the slag cleaning and dredging device, and avoid deformation of the slag cleaning and dredging device during use, which affects normal fishing operations.

[0034] Furthermore, both ends of the cross reinforcement strip are arranged on the inner wall of the end portion of the steel pipe.

[0035] In summary, due to the adoption of the above technical solution, the present invention has at least the following beneficial effects:

[0036] 1. This technical solution uses a dedicated slag removal and dredging device installed on the mechanical equipment structure for clearing floating debris in rivers during the flood season. It not only removes a small amount of slag, but also can remove large amounts of accumulated slag, solving the problem of existing slag removal that cannot be controlled by manpower and the safety of slag removal workers;

[0037] 2. A special slag clearing and dredging device is used, and water-permeable holes are opened on the steel pipe as the main part, which greatly reduces the resistance of the slag clearing and dredging device, reduces the difficulty of catching floating objects, and improves the slag catching effect.

[0038] 3. By arranging reinforcement bars and cross reinforcement bars on the steel pipe as the main part, the structural strength of the slag cleaning and dredging device is further improved to ensure that the slag cleaning and dredging device can salvage floating objects normally and safely.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances. Example

[0046] Figure 1The present invention shows an exemplary embodiment of a slag clearing and dredging device during flood season. The slag clearing and dredging device mainly includes a main body and a connecting part 2 connected to the main body. The connecting part 2 is used to be connected to mechanical equipment. The main body is also provided with a salvage part 3. A salvage groove 4 is formed between the salvage part 3 and the main body. The opening of the salvage groove 4 faces one side of the connecting part 2. In this embodiment, a steel pipe 1 is used as the main body. The connecting part 2 and the salvage part 3 are respectively provided on both sides of the steel pipe 1. The salvage part 3 and the steel pipe 1 are connected. A salvage groove 4 is formed between them, so that during the slag cleaning and dredging process of the slag cleaning and dredging device, floating objects can be accommodated in the salvage groove 4 to complete the salvage. The opening of the salvage groove 4 is toward the side of the steel pipe 1 provided with the connecting part 2, so that after the mechanical equipment is connected to the slag cleaning and dredging device through the connecting part 2, during the catching and rising process, the floating objects can be engaged on the salvage part 3 and will not fall, thus completing the slag cleaning smoothly. The steel pipe 1 is used as the main body, which is not only light in weight and improves the fishing ability, but also has a large cross-sectional moment of inertia and a high structural strength.

[0047] The salvage portion 3 of this embodiment adopts a plurality of U-shaped steel bars 31 welded to the end of the steel pipe 1. The plurality of U-shaped steel bars 31 are arranged along the outer periphery of the steel pipe 1. The U-shaped steel bar 31 includes a first side bar 311 and a second side bar 312 on both sides, and a horizontal bar 313 connected between the first side bar 311 and the second side bar 312. The first side bar 311 of the U-shaped steel bar 31 is welded to the steel pipe 1, and the first side bar 311 is arranged parallel to the axis of the steel pipe 1. A salvage groove 4 is formed between the U-shaped opening of the U-shaped steel bar 31 and the second side bar 312 of the U-shaped steel bar 31 and the steel pipe 1. Figure 1 and Figure 3 As shown, the salvage portion 3 is connected to the steel pipe 1, and the horizontal bar 313 is located outside the end of the steel pipe 1, so as to prevent the steel pipe 1 from affecting the salvage process, so that the slag cleaning and dredging device can salvage floating objects at any position. During the salvage process of the floating objects, the salvage groove 4 can accommodate and clamp the floating objects. The second side bars 312 of the multiple U-shaped steel bars 31 are sharp structures, which can quickly penetrate into the floating objects, so as to prevent the slag cleaning and dredging device from being inconvenient to fix the floating objects during the salvage process. The sharp structure can improve the salvage efficiency.

[0048] As one of the preferred embodiments, Figure 2 As shown, there are six U-shaped steel bars 31, which are evenly arranged on the outer wall of the steel pipe 1. The first side bars 311 of the six U-shaped steel bars 31 are welded to the steel pipe 1. Other numbers of U-shaped steel bars 31 may also be used. The salvage portion 3 of this embodiment uses U-shaped steel bars. Other embodiments include using L-shaped steel bars welded to the steel pipe 1 as the salvage portion 3, or using V-shaped steel bars welded to the main body to salvage floating objects.

[0049] A salvage portion 3 is provided at one end of the steel pipe 1, and a connecting portion 2 is provided at the other end. In this embodiment, the connecting portion 2 includes a first steel plate 21 and a second steel plate 22 welded to the steel pipe 1. The sides of the first steel plate 21 and the second steel plate 22 are welded to the outer wall of the steel pipe 1, so that the plate direction of the first steel plate 21 and the second steel plate 22 is consistent with the axis of the steel pipe 1. As one preferred embodiment, the first steel plate 21 and the second steel plate 22 are arranged in a vertical state, so that the plate angle of the first steel plate 21 and the second steel plate 22 is 90 degrees. The first steel plate 21 and the second steel plate 22 can also be welded on opposite sides of the steel pipe 1. Plate 22, the slag cleaning and dredging device is fixedly installed on the mechanical equipment (excavator or other lift) through the first steel plate 21 and the second steel plate 22. After the connecting part 2 is connected to the mechanical equipment, slag cleaning and dredging are carried out by fishing back and forth in the river channel. The connection method between the first steel plate 21 and the second steel plate 22 and the mechanical equipment includes a welding connection or a connection method with bolt fasteners. The connecting part 2 is formed by welding two steel plates on the steel pipe 1, and the slag cleaning and dredging device is installed on the mechanical equipment through the connecting part 2, thereby improving the connection firmness between the slag cleaning and dredging device and the salvaging mechanical equipment, and ensuring normal and safe salvage of floating objects.

[0050] When the connection part 2 is fixed to the mechanical equipment with bolts and other fixing parts, it has flexibility in use. When floating objects need to be salvaged during the flood season, the slag cleaning and dredging device is installed on the mechanical equipment. During the dry period of the river channel, the slag cleaning and dredging device is disassembled and placed, and the mechanical equipment is used for other purposes.

[0051] In addition, it can be expected that steel columns or other steel sections can also be used as the main body, and a columnar steel structure formed by welding steel bars can also be used as the main body. The steel pipe can be either a round steel pipe or a square steel pipe. When a square steel pipe is used, 1-2 U-shaped steel bars 31 are welded on each of the four sides of the steel pipe. Example

[0052] Figure 4 The present invention shows a slag cleaning and dredging device during the flood season of an exemplary embodiment of the present invention. The slag cleaning and dredging device can further improve the structural strength and operation safety of the slag cleaning and dredging device by strengthening and further optimizing the structure of the main body. The slag cleaning and dredging device mainly includes a steel pipe 1 as the main body. The steel pipe 1 adopts a square steel pipe. A plurality of water-permeable holes 5 are opened along the length direction of the steel pipe 1. The water-permeable holes 5 are opened on the steel pipe 1 in a regular or irregular manner to allow water to pass through the slag cleaning and dredging device during the slag cleaning process, thereby reducing the resistance of the slag cleaning and dredging device operating in water, reducing the working energy consumption of mechanical equipment, and improving the operation efficiency. A reinforcement structure is also provided on the outer wall of the steel pipe 1, which can be specifically a reinforcement strip 6. Figure 4Taking the square steel pipe in the figure as an example, a row of water-permeable holes 5 are opened on each side of the steel pipe 1, and reinforcement strips 6 are arranged around the water-permeable holes 5. The reinforcement strips 6 may specifically include longitudinal reinforcement strips 61 and transverse reinforcement strips 62. The longitudinal reinforcement strips 61 are arranged along the axial direction of the steel pipe 1, and the transverse reinforcement strips 62 are arranged between the longitudinal reinforcement strips 61. The reinforcement strips 6 are made of strip steel plates. First, two strip steel plates are welded on both sides of the water-permeable holes 5 as longitudinal reinforcement strips 61, and then a plurality of transverse reinforcement strips 62 are welded between the two strip steel plates. The two ends of the transverse reinforcement strips 62 are welded to the longitudinal reinforcement strips 61. The transverse reinforcement strips 62 are arranged in a direction perpendicular to the axial direction of the steel pipe. The reinforcement strips 6 can improve the structural strength of the slag cleaning and dredging device to ensure that the slag cleaning and dredging device operates normally and safely salvages floating objects.

[0053] As one of the preferred embodiments, a cross reinforcement bar 7 is provided at the end of the steel pipe 1. The cross reinforcement bar 7 is used to support the inner cavity of the steel pipe 1. The preferred embodiment is to arrange the two ends of the cross reinforcement bar 7 on the inner wall of the end of the steel pipe 1 to form support for the inner cavity of the steel pipe 1, further improve the structural strength of the slag cleaning and dredging device, and avoid deformation of the slag cleaning and dredging device during use, which affects normal fishing operations. The cross reinforcement bar 7 includes a cross horizontal bar 71 and a cross vertical bar 72. The cross horizontal bar 71 first crosses the inner cavity of the steel pipe 1 and is welded to the end of the steel pipe. The cross vertical bar 72 is divided into two separate strip steel plates. The two ends of the two separate strip steel plates are respectively welded to the outer wall of the steel pipe and the cross horizontal bar 71, thereby forming an integrally supported cross reinforcement bar 7, and forming the main body with the steel pipe 1 as a whole.

[0054] The debris clearing and dredging device during the flood season in this embodiment 2 and the debris clearing and dredging device during the flood season in embodiment 1 can both be used for clearing floating objects in rivers during the flood season, and can also be used for clearing and quickly freezing floating objects in old bridges. In old bridges, due to the large number of piers, the ability of all floating objects to pass through the bridge holes is limited. Floating objects will also accumulate and entangle on the piers, seriously threatening the safety of the piers and bridges. The debris clearing and dredging device during the flood season of the present invention can be used to effectively clean up floating objects.

[0055] The above description is only a detailed description of the specific embodiments of the present invention, and does not limit the present invention. Various substitutions, modifications and improvements made by those skilled in the relevant art without departing from the principles and scope of the present invention should be included in the scope of protection of the present invention.
