Drawings
FIG. 1 is a schematic view of the present invention;
in the figure: the device comprises a support frame 1, a positioning support 2, a rotating shaft 3, a balance tractor 4, a movable support arm 5, a counterweight 6, a roller bracket 7, a towing cable positioning nut 8, a roller 9, a roller shaft 10, a discharging vehicle frame 11 and a cross beam 1-1; a support beam 1-2.
Detailed Description
The invention will be further explained by way of example with reference to the accompanying drawings.
Referring to fig. 1, a belt conveyor tripper tow-cable towing arrangement comprises; support frame 1, locating support 2, pivot 3, activity trailing arm 5, counter weight 6, roller bracket 7, tow-cable positioning nut 8, gyro wheel 9, roller shaft 10 and dummy car frame 11, support frame 1 is fixed on dummy car frame 11, locating support 2 fixes on support frame 1, activity trailing arm 5 rotates through pivot 3 to be connected on locating support 2, the one end of activity trailing arm 5 is equipped with counter weight 6, roller bracket 7 fixes the other end at activity trailing arm 5, tow-cable positioning nut 8 is fixed on roller bracket 7, gyro wheel 9 rotates through roller shaft 10 and connects on roller bracket 7.
The specific embodiment is as follows:
referring to the attached drawing 1, a support frame 1 is formed by welding channel steel and angle steel, the channel steel is used as a cross beam 1-1 and is welded on a frame 11 of a dump truck, and the angle steel is used as an inclined support and is welded with the frame 11 of the dump truck to form a triangular stable support.
The positioning support 2 is two columns which are symmetrically welded on channel steel in the support frame 1 and are arranged in parallel, and a rotating shaft 3 is arranged in the middle of the two columns in a hole mode and used for installing a movable supporting arm 5.
The rotating shaft 3, the movable supporting arm 5, the counterweight 6, the roller bracket 7, the towing cable positioning nut 8, the roller 9 and the roller shaft 10 form a balance tractor 4.
