[0001] The utility model relates to the technical field of crawler belts for amphibious excavation equipment, and particularly relates to a crawler belt structure for amphibious excavation equipment. Background Technique

[0002] Due to characteristics such as large contact area with the ground, strong adhesion, and good stability, crawler belt structures are widely used in heavy equipment such as excavators. In complex terrains, crawler belt structures can effectively reduce the risk of equipment slipping and sinking, improving the driving ability and operation efficiency of the equipment. At the same time, crawler belt structures also have good off-road performance and can easily handle rough mountain roads and muddy swamps. In order to further expand the application range of excavation equipment, especially to meet the needs of water operations, amphibious technology has been introduced into excavation equipment.

[0003] When existing excavation equipment conducts amphibious operations, due to the low stability of the excavation equipment on the water surface, if the stability of the device cannot be enhanced during the amphibious operation of the equipment, it may cause the excavation equipment to roll over or capsize, thereby reducing the working state of the excavation equipment during amphibious operations. Therefore, a crawler belt structure for amphibious excavation equipment is proposed. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a crawler belt structure for amphibious excavation equipment to solve the technical problems raised in the above background.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A crawler belt structure for amphibious excavation equipment, including crawler belts. There are two groups of the crawler belts, and a floating component is arranged between the two groups of crawler belts. A turbine component is arranged on one side of the floating component. The floating component includes a fixed block arranged between the two groups of crawler belts. The bottom end of the fixed block is fixedly connected with a housing. A double-shaft motor is installed on one side inner wall of the housing. One output end of the double-shaft motor is fixedly connected with a horizontal shaft. A gear a is fixedly connected to the end of the horizontal shaft far away from the double-shaft motor. A gear b engaged with the gear a is arranged on one side of the gear a. The center of the gear b is rotationally connected with a threaded rod. One side of the threaded rod is rotationally connected with a push plate. An air inlet box penetrating through the bottom is arranged at the bottom end of one side of the housing, and a fixed floating plate is welded to the bottom end of the housing. Air inlet grooves are opened in both the fixed floating plate and the air inlet box. A telescopic floating plate is slidably connected inside the fixed floating plate.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0024] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0025] A crawler structure for a floating excavation device, as Figures 1-6As shown in the figure, it includes a crawler 100. There are two sets of crawlers 100. A floating component 200 is provided between the two sets of crawlers 100. A turbine component 300 is provided on one side of the floating component 200. The floating component 200 includes a fixed block 210 provided between the two sets of crawlers 100. A housing 220 is fixedly connected to the bottom end of the fixed block 210. A double-shaft motor 230 is installed on one side inner wall of the housing 220. A horizontal shaft 240 is fixedly connected to the output end on one side of the double-shaft motor 230. A gear a 250 is fixedly connected to the end of the horizontal shaft 240 far from the double-shaft motor 230. A gear b 260 meshing with the gear a 250 is provided on one side of the gear a 250. A threaded rod 270 is rotatably connected to the center of the gear b 260. A push plate 280 is rotatably connected to one side of the threaded rod 270. An air inlet box 290 penetrating through the bottom is provided at the bottom end on one side of the housing 220. And a fixed floating plate 2920 is welded to the bottom end of the housing 220. An air inlet groove 2910 is provided in both the fixed floating plate 2920 and the air inlet box 290. A telescopic floating plate 2930 is slidably connected inside the fixed floating plate 2920. Floating plates 2940 are slidably connected to both sides inside the telescopic floating plate 2930.

[0026] When the excavation equipment is floating, by starting the double-shaft motor 230, it drives the horizontal shaft 240 on one side to rotate. The horizontal shaft 240 drives the gear a 250 to rotate. The gear a 250 drives the gear b 260 to rotate synchronously. The gear b 260 drives the threaded rod 270 to move, so that the threaded rod 270 drives the push plate 280 to move inside the housing 220, and squeezes the gas inside the housing 220, making the gas enter the air inlet box 290, and then enter the telescopic floating plate 2930 from the air inlet groove 2910 on one side of the air inlet box 290. Under the influence of air pressure, it drives the telescopic floating plate 2930 to move out of the fixed floating plate 2920, which can effectively enhance the floating effect of the excavation equipment. While the telescopic floating plate 2930 moves out, the floating plates 2940 on both sides inside it are simultaneously extended, so that the floating plates 2940 extend to the bottom end of the crawler 100, which can increase the contact area between the excavation equipment and the water surface, further improve its stability on the water surface, and prevent the occurrence of side roll or capsizing. At the same time, the coordinated action of the telescopic floating plate 2930 and the floating plates 2940 enables the excavation equipment to maintain an efficient working state during floating.

[0027] Please refer specifically to Figure 4 , a square block 271 fixedly connected to one end of the threaded rod 270 is provided inside the push plate 280, and guide shafts 272 are slidably connected to both sides inside the push plate 280.

[0028] By setting the square block 271, the rotation of the threaded rod 270 can be effectively prevented. By setting the guide shafts 272, the movement of the push plate 280 can be made more stable.

[0029] Please refer specifically to Figure 5The air inlet groove 2910 extends to the inside of the telescopic floating plate 2930 , sliders 2942 are welded at both ends of the floating plate 2940 , and both sides of the front and rear ends of the fixed floating plate 2920 are fixedly connected with stoppers 2941 .

[0030] The stopper 2941 can effectively prevent the telescopic floating plate 2930 from moving out while driving the floating plates 2940 on both sides to move out synchronously.

[0031] Please refer to Figures 1 to 4 , Figure 6 The turbine assembly 300 includes a connecting shaft 310 fixedly connected to the output end of the other side of the dual-axis motor 230, and the end of the connecting shaft 310 away from the dual-axis motor 230 is fixedly connected to the turbine 320, a circular shell 330 is provided on the surface of the turbine 320, and a circular shaft 350 is welded to the end of the turbine 320 away from the connecting shaft 310, a protective net 340 is installed on one side of the circular shell 330, and one end of the circular shaft 350 passes through one side of the protective net 340 and is fixedly connected to a cutting blade 360.

[0032] When the dual-axis motor 230 is started, it drives the connecting shaft 310 to rotate, and the connecting shaft 310 drives the turbine 320 to rotate. The turbine 320 can further enhance the floating effect of the excavating equipment, so that it can move better on the water surface. The protective net 340 can effectively prevent these debris from being drawn into the turbine 320, thereby protecting the turbine 320 from damage and avoiding equipment failure or shutdown caused by it. The cutting blade 360 ​​can further cut the weeds to improve the operating efficiency of the excavating equipment.

[0033] During use, when the excavating equipment floats, by starting the dual-axis motor 230, the threaded rod 270 drives the push plate 280 to move inside the shell 220, and squeezes the gas inside the shell 220 to make the gas enter the telescopic floating plate 2930. Under the influence of air pressure, the telescopic floating plate 2930 is driven to move out from the fixed floating plate 2920, which can effectively enhance the floating effect of the excavating equipment. When the telescopic floating plate 2930 moves out, the floating plates 2940 on both sides of the inside are extended at the same time, so that the floating plates 2940 extend to the bottom of the crawler 100, which can increase the contact area between the excavating equipment and the water surface, further improve its stability on the water surface, and prevent rollover or capsizing. The synergistic effect of the plate 2930 and the floating plate 2940 enables the excavating equipment to maintain an efficient working state when floating. When the dual-axis motor 230 is started, it drives the connecting shaft 310 to rotate, and the connecting shaft 310 drives the turbine 320 to rotate. The turbine 320 can further enhance the floating effect of the excavating equipment, so that it is easier to move on the water surface. The protective net 340 can effectively prevent these debris from being drawn into the turbine 320, thereby protecting the turbine 320 from damage and avoiding equipment failure or shutdown caused by it. The cutting blade 360 ​​can further cut the weeds to improve the operating efficiency of the excavating equipment. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
