The invention relates to the forging field, and aims to provide a forging method for a magnesium-alloy automobile hub. The forging method for the magnesium-alloy automobile hub comprises the following steps: step I, heating a magnesium alloy rod in a heating furnace; step II, pre-forging the magnesium alloy rod; step III, carrying out pre-profiling forging on disc-shaped blank; step IV, carrying out fine-profiling forging on a pre-profiled hub; step V, carrying out fine-shaping forging on a fine-profiled hub; step VI, transferring the fine-shaped hub to a transfer table for heating through a position transfer device, wherein a heating temperature is controlled to 320 DEG C to 450 DEG C; and step VII, carrying out rim extrusion sizing on the fine-shaped hub. The forging method for the magnesium-alloy automobile hub is relatively high in production efficiency; and the magnesium-alloy automobile hub is compact in texture, is uniform in component, and is relatively high in mechanical strength.

The invention discloses a tunneling and drilling integrated machine which comprises a tunneling machine (1) and two drilling machines (2), wherein each drilling machine (2) comprises a drilling machine part (22) and a mounting frame (21); the two drilling machines (2) are respectively connected on two track frames (11) on two sides of the tunneling machine (1) through the mounting frames (21); and in each drilling machine (2), the drilling machine part (22) is rotatably connected with the mounting frame (21) in a horizontal plane and the drilling machine part (22) can rotate around the front end of the mounting frame (21) in a vertical plane of the length direction is located. Therefore, the drilling machine parts can rotate up and down and swing left and right relative to the mounting frames; the angle and the height of drilling can be adjusted through the relative motion of the drilling machine parts and the mounting frames during the drilling operation, the drilling machines are mounted on the track frames of the tunneling machine and the drilling operation of the drilling machines can be realized without the help of a cutting arm of the tunneling machine; and the drilling machine parts can be rotated and retracted backwards during the tunneling operation and the occupied space can be further reduced.

The invention discloses a mechanical interlocking transmission device of isolating switches. The transmission device comprises a transmission device body, a moving-side mechanical locking device and a fixed-side mechanical locking device. The moving-side mechanical locking device is connected to a moving-side vertical connecting rod of the isolating switches and used for controlling closing and opening of the isolating switch on the moving side. The fixed-side mechanical locking device is connected to a fixed-side vertical connecting rod of the isolating switches and used for controlling closing and opening of the isolating switch on the fixed side. A moving-side pulling rod and a fixed-side pulling rod are fixedly arranged on the moving-side mechanical locking device and the fixed-side mechanical locking device respectively, and the free end of the moving-side pulling rod is connected with the free end of the fixed-side pulling rod through the transmission device body for transmission. When the isolating switch on the moving side is closed, the earthing switch on the fixed side is opened; when the isolating switch on the moving side is opened, the earthing switch on the fixed side is closed. Control over the switch on the moving side and the switch on the fixed side is achieved through the correspondingly arranged moving-side mechanical locking device and fixed-side mechanical locking device, interlocking of the moving side and the fixed side is completed through transition of the transmission device body, and therefore single-side switch closing is achieved in the same state.

The invention discloses a digging and drilling integrated machine which comprises an excavator (1) and a drilling machine (2), wherein the drilling machine (2) comprises a drilling machine part (22) and an installation frame (21); the drilling machine (2) is connected to a cutting arm (11) of the excavator (1) by the installation frame (21); and the drilling machine part (22) is rotatably connected with the installation frame (21) in a horizontal plane, and the drilling machine part (22) can rotate around the front end of the installation frame (21) in a vertical plane where the length direction of the drilling machine part is. Therefore, the drilling machine part can rotate up and down and swing left and right relative to the installation frame; during the drilling operation, the drilling machine part can move with the movement of the cutting arm of the excavator, and adjust the angle and height of the drill holes through the relative movement of the installation frame, so that the drilling machine part can drill higher or lower holes; and during the advancement operation, the drilling machine part is rotated backwardly and taken back, and the space is saved, so that the excavator can perform tunnel boring more freely.
