However, only one spiral propelling wheel is arranged on each of two sides, when the vehicle runs from the flat ground to climb the slope, the front end of the spiral propelling wheel of the double-spiral propelling vehicle and boat leans against the slope, the rear end of the spiral propelling wheel is still on the flat ground, the middle part of the spiral propelling wheel is suspended, and the contact area between the front end and the rear end of the spiral propelling wheel and the ground is too small, so that the propelling wheel of the double-spiral propelling vehicle and boat slips and cannot pass through corners of the flat ground and the slope. When the vehicle runs to the ridge, the screw propulsion vehicle and ship can be quickly turned over from one side of the ridge to the other side of the ridge, and the vehicle turning accident is easily caused. The difficulty of the screw propulsion vehicle in passing on flat ground and at the corners of slopes is a factor that limits its development.

Turbine bearings 7 at two ends of the turbine 6 are respectively connected in bearing mounting holes of the turbine bearing seat 8, and the outer ring of the turbine bearing 7 and the bearing mounting holes of the turbine bearing seat 8 are in interference fit.
As shown in fig. 3, the turbine bearing seat 8 includes a bottom plate 801, a fixed support plate 802 is vertically connected to the bottom plate 801, an installation step 804 is fixedly disposed on one side of the fixed support plate 802, and a movable support plate 803 is detachably connected to the installation step 804 through a connector. The fixed support plate 802 and the movable support plate 803 are provided with bearing mounting holes at the same height position, and the turbine bearing 7 is arranged in the bearing mounting holes.
As shown in fig. 4, the mounting steps 804 include a first mounting step 805 and a second mounting step 806 that are horizontally arranged side by side, upper end surfaces of the first mounting step 805 and the second mounting step 806 are arranged to be staggered from each other in the height direction, an upper end surface of the first mounting step 805 is in a straight line structure, and an upper end surface of the second mounting step 806 is in a V-shaped structure.
As shown in fig. 5, the movable plate 803 is provided with a first fitting step 807 and a second fitting step 808 in parallel facing the lower end surface of the mounting step 804, the lower end surface of the first fitting step 807 is matched and connected with the upper end surface of the first mounting step 805, and the lower end surface of the second fitting step 808 is matched and connected with the upper end surface of the second mounting step 806.
As shown in fig. 1 and 6, two ends of the screw rod 10 extend out of the bearing mounting holes of the turbine bearing seat 8, one end of the screw rod 10 is rotatably connected to one end of the adapter plate 11 through a first pin, the other end of the adapter plate 11 is rotatably connected to one end of the two guide rods 12 through a second pin, the other ends of the two guide rods 12 are inserted into the blind holes at one end of the screw propulsion wheel 13, and the guide rods 12 can axially extend and retract along the blind holes of the screw propulsion wheel 13. The other end of the spiral propelling wheel 13 is rotatably connected to the supporting plate 14 through a third pin shaft.
As shown in FIG. 7, when the invention is applied, two sets of the invention are arranged on the two sides of the vehicle hull 16 in a bilateral symmetry mode. The invention changes the connection angle of the spiral propelling wheels 13 by adjusting the height of the connection part between the two spiral propelling wheels 13 at the same side, thereby increasing the ground contact area, preventing the middle part of the spiral propelling wheels 13 from hanging and slipping and being convenient for climbing.
The invention defines the included angle formed by the intersection of the axes of the two spiral propelling wheels 13 as the connection angle. When the spiral propulsion vehicle runs on flat ground, the two axes of the spiral propulsion wheel 13 are overlapped, the connection angle is 180 degrees, the ground contact area of the spiral propulsion wheel 13 reaches the maximum, and the running slip can be prevented. When the spiral propulsion vehicle runs to the corner between the flat ground and the slope, in order to avoid the middle connecting part of the spiral propulsion wheels 13 from being suspended, the connecting parts of the two spiral propulsion wheels 13 are moved downwards, the connecting angle is adjusted to be less than 180 degrees, and the connecting angle is adjusted back to be 180 degrees to start climbing after the spiral propulsion vehicle runs through the corner. When the spiral propelling car finishes climbing and reaches the ridge, if the connection angle of the spiral propelling wheels 13 is 180 degrees or even more than 180 degrees, the spiral propelling car can be rapidly turned from one side of the slope to the other side of the slope when the spiral propelling car continues to move forward, and the car turning accident is easy to happen, therefore, the connection part of the two spiral propelling wheels 13 needs to be moved upwards, the connection angle is adjusted to be more than 180 degrees, the front spiral propelling wheel 13 slowly moves to the other side of the slope, then the connection angle is slowly adjusted back to 180 degrees, and the spiral propelling car starts to move downhill.
When the connection angle is reduced and adjusted by 180 degrees, the worm 3 is driven by the positive rotation of the servo motor 1, so that the worm wheel 6 is driven to rotate, the screw rod 10 is driven to vertically move downwards, the two guide rods 12 slowly extend out of the blind holes of the spiral propelling wheels 13 at the moment, the two spiral propelling wheels 13 rotate around the hinged positions at the two ends, and the connection angle of the spiral propelling wheels 13 is gradually reduced. When the connection angle is gradually increased from less than 180 degrees to more than 180 degrees, the servo motor 1 rotates reversely, the screw rod 10 is driven to move upwards continuously after being transmitted by the worm rod 3 and the turbine 6, the two spiral propelling wheels 13 rotate around the hinged parts at the two ends, and the connection angle is gradually increased. In the process of increasing the connection angle from less than 180 degrees to 180 degrees, the two guide rods 12 are slowly inserted into the blind holes of the spiral propelling wheel 13, when the connection angle is 180 degrees, the insertion length of the guide rods 12 reaches the maximum, and when the connection angle is continuously increased from 180 degrees, the two guide rods 12 gradually extend out of the blind holes of the spiral propelling wheel 13.
The above description is intended to be illustrative and not restrictive, and the scope of the invention is defined by the appended claims, which may be modified in any manner within the scope of the invention.
