[0027] like Figure 1 As shown in FIG9 , the utility model provides a new energy wheeled self-moving tail, comprising a tail frame 1, with front and rear wheel assemblies 2 respectively arranged on the left and right sides of the tail frame 1, the wheel assembly 2 comprising a hub motor 4, the hub motor 4 being rotatably arranged on the tail frame 1, a wheel 5 being arranged on the outside of the hub motor 4, and a steering electric cylinder 6 being arranged between the hub motor 4 and the tail frame 1; two groups of front and rear adjustment assemblies 3 are arranged on the tail frame 1, the adjustment assemblies 3 comprising two left-right symmetrical support frames 7, a lifting electric cylinder 8 being respectively arranged on the two support frames 7, a slide 9 being respectively arranged at the lower end of the two lifting electric cylinders 8, the two slides 9 being slidably arranged on the same slide shoe 10, and a transverse electric cylinder 11 being respectively arranged between each slide 9 and the slide shoe 10.

The transverse electric cylinder 11 is horizontally arranged along the left and right directions. One end of the cylinder bottom of the transverse electric cylinder 11 is connected to the fixed seat through the fourth pin shaft 24, and one end of the piston rod of the transverse electric cylinder 11 is connected to the slide 9 on the same side through the fifth pin shaft 25.

[0034] A material platform 26 is fixedly mounted on the tail frame 1. The material platform 26 is a horizontally arranged square plate-like structure. A vertical fixed leg is fixedly mounted at each of the four corners of the lower end face of the material platform 26. These four fixed legs are fixedly connected to the left longitudinal beam 12 and the right longitudinal beam 13 of the tail frame 1. Downhole cameras 27 are fixedly mounted at both the front and rear ends of the upper end face of the tail frame 1. An electronic control system 28 and an energy storage power supply 29 are fixedly mounted on the material platform 26. The electronic control system 28 is connected to the downhole camera 27, the wheel hub motor 4, the steering cylinder 6, the lifting cylinder 8, and the traverse cylinder 11. The energy storage power supply 29 is electrically connected to the electronic control system 28, the downhole camera 27, the wheel hub motor 4, the steering cylinder 6, the lifting cylinder 8, and the traverse cylinder 11. The electronic control system 28 controls the movement of the entire wheeled self-propelled tail and incorporates comprehensive protection features, including anti-slip protection, coal pile protection, anti-tracking protection, temperature protection, smoke protection, automatic sprinkler system, speed protection, anti-tear protection, and bidirectional emergency stop protection. The electronic control system 28, combined with the downhole camera 27, enables remote control. A stored energy source 29 provides clean, pollution-free power for the entire wheeled self-propelled tail.

[0035] The working principle of this utility model is:

[0036] The hub motors 4 of all wheel assemblies 2 rotate all wheels 5, enabling the vehicle to move forward or backward. To steer, the steering cylinders 6 of the wheel assemblies 2 are controlled to extend and retract, adjusting the angles of the wheels 5 and steering the vehicle as a whole. While the vehicle is moving, all lift cylinders are retracted, lifting the skid shoe 10 as a whole, freeing it from the ground.

[0037] When the left-right position of the self-propelled tail needs to be adjusted, the piston rod of the lifting cylinder is controlled to extend, causing the lifting cylinder to lower the sliding shoe 10 as a whole, so that the sliding shoe 10 contacts the ground. The piston rods of the lateral cylinders on both sides are then controlled to extend and retract, causing the slides 9 on both sides to slide within the slide grooves of the sliding shoe 10, thereby driving the support frames 7 on both sides to slide as a whole left and right. The support frames 7 on both sides drive the tail frame 1 as a whole to slide left and right, thus achieving the left-right position adjustment of the self-propelled tail as a whole.

[0038] The spiral drum 16 automatically rotates the residual coal on the conveyor belt through the combined rotation of the outer spiral steel belt 19 and the inner cone 18, reducing the difficulty of manual coal cleaning and avoiding the occurrence of safety accidents during the coal cleaning process.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
