A railway dumper with automatic unloading detection device
A self-tipping railway car with an automatic unloading detection device, belonging to the field of railway transportation, includes a self-tipping railway car with axle suppression mechanism. The left and right ends of the car's bottom are respectively mounted on the vehicle via a first cylinder and a second cylinder. A solenoid valve is mounted on the vehicle to control the intake and exhaust of the first and second cylinders. A battery box and a power supply box are mounted on the side bolster beams of the vehicle and are electrically connected. A signal transceiver is installed inside the power supply box and is electrically connected to a time relay. The time relay is electrically connected to the solenoid valve, controlling the first stage of the solenoid valve's operation. A first synchronous signal transceiver is installed inside the power supply box, and a second synchronous signal transceiver is installed on the end wall of the self-tipping railway car. A limit switch device detects the opening and closing status of the side doors of the self-tipping railway car. This design solves the problem of automatic unloading of the self-tipping railway car with axle suppression mechanism, eliminating the safety hazard of tipping over during the unloading process.

A mine car with easy discharge
This utility model discloses a mine car that facilitates unloading, relating to the field of mine car technology. It includes: a frame with a bucket rotatably connected to it; a pair of rotating shafts, fixedly mounted on both ends of the bucket, with the shafts located on one side of the bucket's vertical centerline; a pair of end plates, fixedly mounted on both ends of the frame's upper surface, with the rotating shafts rotatably connected to the end plates; and a tipping switch assembly, including a rotating rod rotatably mounted on the upper end of the end plates, a stop bar fixedly mounted on one end of the rotating rod, and a stop block fixedly mounted on the bucket corresponding to the stop bar. This utility model allows the bucket to become unrestrained as the mine car moves forward. By positioning the rotating shafts on one side of the bucket's vertical centerline, a center of gravity shift effect is created, allowing the bucket to tip over under its own weight, emptying the material inside. This eliminates the need for complex mechanical structures, reducing the mine car's manufacturing cost, and the simple structure reduces maintenance costs.

A coal mine transport device
This utility model discloses a coal mine transportation device, relating to the field of coal mine transportation technology, comprising: a frame; two arc-shaped grooves symmetrically arranged at both ends of the top of the frame; and two limiting grooves symmetrically arranged on the arc-shaped grooves. The vertical cross-section of the limiting grooves is set as an isosceles trapezoid with a larger upper section and a smaller lower section, and the vertical cross-section of the limiting grooves increases uniformly from the center of the arc-shaped grooves to both sides. When the U-shaped bucket is pulled to one side, the inclined block moves upward along the limiting grooves and penetrates into the limiting grooves. During the pulling process, due to the design of the inclined block and the limiting grooves with a larger upper section and a smaller lower section, the U-shaped bucket will not easily slide down when it is pulled to one side and tilted, improving the stability of tilting and dumping. The requirements for the pulling angle are lower, and the operator does not need to precisely control the direction, greatly simplifying the operation process.

Suspension steering mechanism and off-highway mining dump truck
This disclosure proposes a suspension steering mechanism and an off-highway mining dump truck. The suspension steering mechanism includes a steering knuckle, a steering arm, a mounting key, and a connecting member. The steering knuckle has a first mounting plane with a first keyway. The steering arm has a second mounting plane with a second keyway. The steering knuckle and steering arm are assembled via the first and second mounting planes, with the first and second keyways arranged opposite to each other. The second mounting plane has an angle greater than 90° and less than 180° with the steering plane of the suspension steering mechanism. The mounting key is accommodated in the first and second keyways. The connecting member connects the first and second mounting planes. Through the above design, this disclosure solves the stress concentration problem existing in off-highway mining dump trucks during operation, ensures the effective connection of the connecting member, and improves the reliability and stability of the mine truck steering system.
