Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically to an electric drive device adapted for long-distance movement of electric roller drills. Background Technology

[0002] An electric rotary drill is a drilling device primarily used in open-pit mining operations. Through its unique tricone drill bit and crushing mechanism, the electric rotary drill can generate crushing and shearing action on the rock surface, thus drilling efficiently. The drilling speed of an electric rotary drill increases proportionally with the drill bit pressure, making its drilling speed significantly higher than that of percussion drills and down-the-hole drills; it is typically more than 5 times faster than percussion drills and 2 times faster than down-the-hole drills.

[0003] In open-pit mine production organization, rotary drilling rigs, as the main drilling equipment in large mines, need to be moved over long distances according to changes in the work site. Currently, there are two main ways to move them: one is to connect the drilling rig to the 6kV high-voltage line inside the mining area via a high-voltage cable, and the other is to power the drilling rig via a 6kV mobile high-voltage power vehicle.

[0004] Existing high-voltage cable power supply requires workers to move the cable, which is labor-intensive and inefficient. Furthermore, the cost of equipment investment is too high when using a mobile high-voltage power vehicle for power supply. Therefore, it does not meet the current needs. In response, we propose an electric drive device that is suitable for long-distance movement of electric rotary drills. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electric drive device adapted for long-distance movement of an electric rotary drill, comprising a traction drive mechanism, wherein an electric rotary drill is mounted on the upper end of the traction drive mechanism, and a mobile low-voltage power generation mechanism is mounted on the rear end of the electric rotary drill, wherein the mobile low-voltage power generation mechanism comprises a generator cabinet, and a generator set is mounted on the inner side of the generator cabinet.

[0010] Preferably, a power distribution cabinet is fixedly installed on the inner side of the rear end of the electric rotary drill. The generator set is connected to the power distribution cabinet through a cable group. Both ends of the traction rod are rotatably connected to the generator cabinet and the electric rotary drill through pins. The power distribution cabinet is electrically connected to the drive motor.

[0011] Preferably, the electric rotary drill is rotatably connected to the drill chassis via a chassis steering unit, and the track is fitted onto the outside of the drive gear and auxiliary guide wheel and is rotatably connected to the connecting shaft sleeve via the drive gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model connects the generator cabinet and the electric rotary drill rig via a traction rod. A power distribution cabinet is installed on the electric rotary drill rig, connecting the power distribution cabinet to the generator set inside the generator cabinet via a cable assembly. The power distribution cabinet is also electrically connected to the drive motor. The generator set generates electricity inside the generator cabinet and transmits the electrical energy to the power distribution cabinet via the cable assembly. The power distribution cabinet then controls the power distribution to the electric rotary drill rig and the drive motor. The electric rotary drill rig, via the traction rod, synchronously moves the generator cabinet under the support of the support wheels, enabling the generator cabinet to provide mobile power to the electric rotary drill rig.

This enables the drive gear to drive the electric rotary drill through the track. The transmission speed of the two adjacent differentials is adjusted differently. Then, the differential can drive the two adjacent drive gears to rotate differently through the transmission shaft and connecting bushing, thereby realizing the steering movement of the electric rotary drill.

Track 103 is fitted onto the outside of drive gear 106 and auxiliary guide wheel 105 and is rotatably connected to connecting shaft sleeve 107 via drive gear 106. A protective crossbeam 108 is installed between two adjacent wheel support frames 104. A drive unit is installed on the inner side of the front end of the protective crossbeam 108, so that drive gear 106 drives electric rotary drill through track 103. Then, electric rotary drill synchronously drives generator cabinet 201 to move under the support of support wheel 202 via traction rod 203.

[0025] The drive unit includes a gearbox 111, a drive motor 113 is fixedly mounted on one side of the gearbox 111, and connecting shafts 112 are rotatably connected to the inner sides of both ends of the gearbox 111. Differentials 110 are mounted on the ends of the two connecting shafts 112 away from the gearbox 111, and drive shafts 109 are mounted on the inner sides of the differentials 110.

The transmission speed of the two adjacent differentials 110 is adjusted differently, and the differentials 110 can drive the two adjacent drive gears 106 to rotate differently through the transmission shaft 109 and the connecting bushing 107, thereby enabling the electric rotary drill to turn and move.
