Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of hulls, and more specifically, particularly relates to an auxiliary traveling device and method for shallow water area road paving. Background Art
[0002] At present, due to the characteristics of assault boats such as fast speed on the water, strong flexibility and maneuverability, simple operation, large carrying capacity, and strong adaptability to complex outdoor waters, they are widely used in urban waterlogging, reservoirs, water surfaces and other scenarios to carry out water search and rescue, water surface rescue, personnel transfer, material transportation, water survey and other tasks.
[0003] After urban waterlogging and other disasters occur during the flood season, a large amount of water accumulates on urban roads and boats are needed to pass through. However, due to the different road elevations and the presence of a large number of overpasses, the depth of water on urban roads varies, resulting in intermittent waterlogging scenes, and even shallows for several kilometers. It is necessary to pass through multiple waterlogging areas and non-waterlogging sections to reach the destination. Transport vehicles and lifting equipment cannot move forward after transporting the speedboat to the first waterlogging area. After the speedboat passes the first waterlogging area, since the speedboat is designed to travel in water with a certain depth, it does not have the need to travel in shallow waters. If it travels in waters that do not meet the draft depth requirements of the speedboat, there are hidden dangers of running aground and beating. The speedboat cannot pass through shallows or non-waterlogging areas between two overpasses, which seriously restricts the efficiency of emergency rescue. In addition, since the speedboat is large in size and heavy in weight, it needs to be moved by crane or truck for lifting operations, which is not convenient for manpower to move short distances.
[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and deficiencies, and an auxiliary traveling device for shallow water road paving is provided, in order to achieve a more practical purpose. Summary of the invention

When the first wheel 29 and the second wheel 35 need to rise, the user rotates the threaded rod 16 to drive the second baffle ring 19 to rise. The first wheel 29 and the second wheel 35 are determined by arranging a first retaining ring 18 and a second retaining ring 19 outside the threaded rod 16 to determine the height of the first wheel 29 and the second wheel 35 on both sides of the assault boat 1. The first slide bar 25 is located on the side of the steering rod 26. Two third retaining rings 27 are fixedly sleeved on the outer wall of each steering rod 26. The two third retaining rings 27 are located on the upper and lower sides of the upper fixing frame 24. A steering handle 37 is fixedly installed on the top of each steering rod 26.
[0021] A second sliding bin 32 is provided at the bottom of each second wheel assembly frame 3, and a second sliding groove 31 is provided on the side wall of each second wheel assembly frame 3, and the second sliding groove 31 and the second sliding bin 32 are connected, and each lifting frame 33 slides in the second sliding bin 32.

The rotation of the two first wheels 29 can drive the assault boat 1 to turn, and the two third retaining rings 27 can ensure that the steering rod 26 rotates in the upper fixed frame 24, and at the same time can keep the upper fixed frame 24 driving the bogies 28 to rise and fall, and a second sliding rod 34 is fixedly installed on the top of each lifting frame 33, and each second sliding rod 34 slides through the second wheel assembly frame 3, and each connecting frame 2 and the upper fixed frame 24 are connected in the first sliding groove 22, and each connecting frame 2 and the lifting frame 33 are connected in the second sliding groove 31.
[0022] Working principle: In the first step, the assault boat 1 is placed on the bracket 12, and the vehicle can drive the assault boat 1 to move through the bracket 12. When the assault boat 1 floats forward in the water, the lowest heights of the first wheels 29 and the second wheels 35 on both sides of the assault boat 1 are higher than the bottom of the boat. When the assault boat 1 cannot float in shallow water, the user drives the threaded rod 16 to rotate by rotating the two turntables 17. The threaded rod 16 rotates outside the fixed collar 15 and moves downward. The threaded rod 16 moves downward to drive the connecting frame 2 to move downward. The connecting frame 2 moves downward to drive the first wheel 29 and the second wheel 35 to move downward. The first wheel 29 and the second wheel 35 on both sides of the assault boat 1 are rotated. The second wheels 35 descend and contact the ground, and prop up the assault boat 1. At this time, the assault boat 1 can be pushed on the ground by people. By installing the first wheels 29 and the second wheels 35 that can be grounded under the assault boat 1, the assault boat 1 can travel smoothly in shallow water areas that do not meet the draft depth requirements or on paved roads, avoiding hidden dangers such as running aground and beating. In waterlogging rescue, the assault boat 1 can switch freely between waterlogging and non-waterlogging areas, thereby improving the efficiency of emergency rescue. Before and after use, the assault boat 1 can be moved by relying on the first wheels 29 and the second wheels 35 combined with human drive, reducing the links of crane and truck lifting operations.
[0023] In the second step, when the user lowers the first wheel 29 and the second wheel 35, the user rotates the two turntables 17, and the rotation of the two turntables 17 drives the two threaded rods 16 to move downward in the fixing collar 15. The downward movement of the threaded rod 16 drives the first retaining ring 18 to move downward, and stops when the first retaining ring 18 moves downward and contacts the top of the fixing collar 15. When the first wheel 29 and the second wheel 35 need to rise, the user rotates the threaded rod 16 to drive the second retaining ring 19 to rise, and stops when the second retaining ring 19 rises and contacts the bottom of the fixing collar 15. The height of the first wheel 29 and the second wheel 35 is determined by arranging the first retaining ring 18 and the second retaining ring 19 outside the threaded rod 16, thereby effectively ensuring that the first wheel 29 and the second wheel 35 on both sides of the assault boat 1 are at the same height, and at the same time ensuring that the first wheel 29 and the second wheel 35 reach a fixed position when rising, thereby avoiding the situation where there is a height difference between the first wheel 29 and the second wheel 35; When the threaded rod 16 descends, the threaded rod 16 descends and drives the connecting frame 2 to descend. The connecting frame 2 descends and drives the upper fixing frames 24 and the lifting frame 33 at both ends to descend. At the same time, the two ends of the connecting frame 2 slide in the first slide groove 22 and the second slide groove 31. The upper fixing frame 24 moves downward and drives the bogie 28 to move downward through the steering rod 26. The bogie 28 moves downward and drives the first wheel 29 to move downward. The lifting frame 33 moves downward and drives the second wheel 35 to move downward. By designing the first wheel 29 and the second wheel 35 to be synchronously lowered or raised by the connecting frame 2, the operation speed can be improved, and at the same time, the height of the first wheel 29 and the second wheel 35 is ensured to be unified, thereby improving the convenience of operation. When the upper fixed frame 24 and the lifting frame 33 move up and down, the upper fixed frame 24 will drive the first slide bar 25 to slide in the first wheel assembly frame 21, and the lifting frame 33 will drive the second slide bar 34 to slide in the second wheel assembly frame 3. The first slide bar 25 and the second slide bar 34 can maintain the stability of the upper fixed frame 24 and the lifting frame 33 when moving, and improve the stability of the first wheel 29 and the second wheel 35 when moving.
[0024] In the third step, when the assault boat 1 moves on the ground through the first wheel 29 and the second wheel 35, the user can rotate the two steering handles 37 to drive the two bogies 28 to rotate. The rotation of the two bogies 28 will drive the two first wheels 29 to rotate. The rotation of the two first wheels 29 can drive the assault boat 1 to turn. The two third retaining rings 27 can ensure that the steering rod 26 rotates in the upper fixed frame 24, and at the same time, the upper fixed frame 24 can keep driving the bogies 28 to rise and fall. By designing the two first wheels 29 to be steerable, the convenience of the assault boat 1 when moving on the ground can be improved.
[0025] Optionally, the method for using the shallow water area road paving auxiliary traveling device comprises: 1. Preparation Device assembly: Place the assault boat 1 on the bracket 12, and fix the fixed lifting ring 11 to the end of the first support frame 13. Check whether the first wheel 29, the second wheel 35 and related connecting parts (such as the bogie 28, the lifting frame 33, etc.) are firmly installed. Make the threaded rod 16 correctly installed in the fixed collar 15 through the thread, and install the turntable 17, the first retaining ring 18 and the second retaining ring 19 in place.
[0026] 2. Operation Phase Lifting and lowering of the first wheel and the second wheel: When the speedboat 1 needs to move in shallow water or on a paved road, the user rotates the two turntables 17 to drive the threaded rod 16 to rotate. The threaded rod 16 rotates and moves downward, driving the first wheel 29 and the second wheel 35 to descend synchronously through the connecting frame 2 until they contact the ground and support the speedboat 1. The user can determine the height of the wheels by observing the relative positions of the first stop ring 18, the second stop ring 19 and the fixing ring 15, so that the wheels on both sides are at the same height.
[0027] Movement and steering: After the speedboat 1 is supported by the first wheel 29 and the second wheel 35, a person can push the speedboat 1 to move on the ground. If steering is required, the user can rotate the two steering handles 37 to drive the first wheel 29 to rotate through the bogie 28, thereby achieving steering of the speedboat 1. During the steering process, the two third retaining rings 27 enable the steering rod 26 to rotate stably in the upper fixing frame 24, while maintaining the stability of the upper fixing frame 24 driving the bogie 28 to rise and fall.
[0028] Stability guarantee: When the upper fixing frame 24 and the lifting frame 33 move up and down, the first slide bar 25 and the second slide bar 34 slide in the first wheel assembly frame 21 and the second wheel assembly frame 3 respectively to maintain stability during movement. The user should always pay attention to the moving state of the speedboat 1, adjust the wheel height and steering angle in time, and drive safely.
[0029] 3. Ending Stage Wheel recovery: When the speedboat 1 completes the moving task, the user needs to drive the threaded rod 16 to rotate and move upward by rotating the turntable 17, thereby driving the first wheel 29 and the second wheel 35 to rise synchronously and retract to the initial position.
[0030] Device cleaning and maintenance: Clean dirt, water stains and other dirt on the assault boat 1 and the auxiliary travel device. Check whether each component is damaged or worn, and replace or repair it in time if necessary. Store the device in a dry and ventilated place to avoid long-term exposure to sunlight and rain, which may cause aging of the components.
