[0001] The utility model relates to mining equipment, in particular to a working vehicle axle for a tunnel, which is composed of a swing frame, a steering knuckle, a bridge housing and a brake. Background Art
[0002] At present, there is a kind of axle for a tunnel work vehicle disclosed on the market, and its structural features are as follows: it is composed of a swing frame, a steering knuckle, a bridge housing and a brake, wherein one end of the steering knuckle is respectively provided at both ends of the bridge housing, and the brake is provided at the other end of the steering knuckle, the swing frame is installed in the middle of the bridge housing, the frame is movably connected to the swing frame through a swing block and a short shaft, and the two sides of the frame are connected to the axle through hydraulic cylinders, thereby solving the problem of left and right shaking. However, since the road surface in the tunnel is uneven, the work vehicle will not only swing left and right when walking, but also swing forward and backward and up and down. The front and back up and down swing of its frame is a rigid swing, and therefore, it is easy to affect the life of the work vehicle and cause safety hazards. Summary of the invention
[0003] The utility model aims to provide a working vehicle axle for a laneway which can not only effectively reduce the left-right swing of a vehicle frame, but also effectively alleviate the up-and-down swing of the vehicle frame front and back, thereby increasing the service life of the working vehicle.
[0004] To achieve the above-mentioned purpose, the utility model discloses a vehicle axle for a tunnel working vehicle, which is composed of a swing frame, a steering knuckle, a bridge housing and a brake. The two ends of the bridge housing are respectively provided with one end of the steering knuckle, the brake is provided at the other end of the steering knuckle, the swing frame is installed in the middle of the bridge housing, and the swing frame is connected to the bridge housing through a rotating shaft and a rotating shaft seat.
[0005] Grooves are respectively arranged at both ends of the rotating shaft along the radial direction.
[0006] Stoppers that can cooperate with the groove are respectively arranged at the two outward ends of the rotating shaft seat, so that the bottom length of the stopper extending into the groove is smaller than the bottom length of the groove. The stopper and the groove are clearance-matched, which is convenient for controlling the arc of the frame to swing up and down.
[0007] The swing frame is composed of a sleeve, a sleeve seat, a base plate, a swing block, a rotating shaft and a rotating shaft fixing seat. The sleeve is arranged on the upper surface of the base plate through the sleeve seat. The swing block that can be connected to the frame is movably connected to the sleeve through a pin shaft. The rotating shaft is installed on the lower surface of the base plate through the rotating shaft fixing seat, and the axis of the sleeve is perpendicular to the axis of the rotating shaft.
[0008] At least two arc-shaped protrusions are evenly distributed on the end surface of the pendulum block close to the sleeve.
[0009] At least two arc-shaped grooves are evenly distributed on the end surface of the sleeve close to the swing block, which can cooperate with the arc-shaped protrusions on the end surface of the swing block, so that the arc length of the bottom of the arc-shaped protrusion extending into the arc-shaped groove is smaller than the arc length of the bottom inside the arc-shaped groove. The arc-shaped groove and the arc-shaped protrusion are matched with clearance, which is convenient for controlling the arc of the left and right swing of the frame.
[0010] After adopting this structure, since the swing frame is connected to the bridge housing through the rotating shaft and the rotating shaft seat, it can not only effectively reduce the left and right swing of the frame, but also effectively alleviate the up and down swing of the frame front and back, thereby improving the service life of the working vehicle.
