DETAILED DESCRIPTION

[0017] The utility model is further described in detail below with reference to the accompanying drawings.

[0018] Activate the power cable connection device of the coal feeder drive motor, such as Figure 1 As shown, it includes a basic support frame 11, a non-vibration side device 10, a vibration side device and a single-core connected power cable 7, wherein a support column is placed on the side of the basic support frame, the non-vibration side device is installed above the support column, the vibration side device is installed above the basic support frame, the vibration side device is connected to the basic support frame through a spring, and one end of the single-core connected power cable is fixed to the non-vibration side device, and the other end is fixed to the vibration side device.

[0019] Among them, the supporting column is L-shaped, with one end fixed on the activated coal feeder foundation support frame and the other end at 90 degrees to it. An arc-shaped cable fixing is installed on the top to prevent scratches on the power cable. It maintains a distance of 300mm from the fixed end on the vibration side and is installed at 90 degrees vertically to the vibration box. It can effectively release the kinetic energy generated by the shaking of the power cable and prevent damage to the cable at the non-vibration end.

[0020] The single-core connecting power cable uses three single-core cables to replace the original three-core special cables. The length is 1000mm. When used in conjunction with the anti-bending sheath, it can effectively release the kinetic energy generated by the vibration of the power cable, greatly improve the bending resistance of the connecting cable, and protect the vibration end and non-vibration side of the power cable from premature damage.

[0021] The non-vibration side device includes a non-vibration side terminal box 9 and a non-vibration side fixing part 8, wherein the non-vibration side terminal box is installed on the side of the supporting column, the non-vibration side fixing part is installed on the top of the supporting column, and one end of the single-core connected power cable is connected to the non-vibration side terminal box and fixed by the non-vibration side fixing part.

[0022] The vibration side device includes a vibration box 1, a drive motor 2, a motor connecting cable 3, a vibration side cable terminal box 4, a vibration side cable fixing part 5 and an anti-bending sheath 6, wherein the top of the basic support frame is connected to the vibration box by a spring, and the sides of the vibration box are provided with a drive motor, a vibration side cable terminal box and a vibration side cable fixing part from top to bottom. The drive motor is connected to the vibration side cable terminal box through the motor connecting cable, and the other end of the single-core connected power cable is connected to the vibration side terminal box. At the same time, the single-core connected power cable passes through the middle of the anti-bending sheath and is fixed by a locking nut on the vibration side cable fixing part.

[0023] The single-core connecting power cable is composed of three independent rubber cables, and the vibration kinetic energy generated by the vibrating box is distributed to the three independent rubber cables at the same time.

[0024] The single-core connected power cable is in a U shape between the non-vibration side devices and the vibration side device.

[0025] The working principle of the utility model is:

[0026] The single-core power cable of the power cable connection device of the activated coal feeder is fastened by the vibration side cable fixing piece at the vibration box. The single-core power cable passes through the middle of the anti-bending sheath and is fastened by the locking nut on the vibration side cable fixing piece. The vibration side of the single-core power cable is connected to the vibration side cable terminal box, and the vibration side cable terminal box is connected to the drive motor by the motor connection cable, and vibrates at the same time as the vibration box, so there is no cable jitter problem.

[0027] The single-core power cable combined with the anti-bending sheath can effectively release the shaking kinetic energy generated by the vibrating box onto the single-core power cable, and release it in sequence from the cable fixings on the vibrating side to the cable fixings on the non-vibrating side. When it reaches the cable fixings on the non-vibrating side, the vibration kinetic energy on the single-core power cable is almost zero, effectively protecting the single-core power cable at the non-vibrating side cable fixings.

[0028] The single-core connected power cable is composed of three independent rubber cables. The shaking kinetic energy generated by the vibration box is distributed to the three independent rubber cables at the same time, which increases the bending resistance of the single-core connected power cable by times. The supporting column is installed on the basic supporting frame on the non-vibration side. The non-vibration side cable fixing is installed at a distance of 300mm between the top of the supporting column and the vibration side cable fixing. One side of the single-core connected power cable is connected to the vibration side cable terminal box, and the other side is connected to the non-vibration side cable terminal box, which are fastened by the vibration side cable fixing and the non-vibration side cable fixing respectively.

[0029] The single-core connected power cable is in a U-shape between the cable fixing on the vibration side and the cable fixing on the non-vibration side. The single-core connected power cable moves up and down with the vibration box at the cable fixing on the vibration side, and its potential energy is released at all parts of the three cables. The 1000mm length of the cable just suppresses the resonance caused by the movement of the vibration box, which greatly improves the service life of the single-core connected power cable.

[0030] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention includes but is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
