8 results about "Rollover" patented technology

An actuation mechanism is used with the deployment apparatus mounting a running board on an automotive vehicle for laterally outward movement to increase rollover resistance for the vehicle. The actuation mechanism includes a cup with a hollow tube attached thereto to provide a path for the movement of a ball from the cup into engagement with the latching mechanism on the deployment apparatus. The ball is retained within the cup member until the actuation mechanism and the automotive vehicle to which it is mounted tilts to a minimum roll angle, whereupon the ball is released to roll down the hollow tube into engagement with the latching mechanism of the deployment apparatus. In one embodiment, a single cup with a pair of laterally extending tubes directs the ball to the deployment apparatus that requires actuation. In other embodiments, a separate actuation mechanism is provided for each respective deployment apparatus.

The invention discloses a fixing device of a free-sliding safety wire for an inclined well and a mine car and relates to the technical field of mine equipment. The fixing device is designed for preventing the free-sliding safety wire from falling off. The free-sliding safety wire for the inclined well comprises a base, a first fixing module and a second fixing module. The first fixing module is fixed to the base and comprises a first pressing surface. The second fixing module comprises a second pressing surface, and the second fixing module is slidably connected to the base to enable the second pressing surface to abut against the first pressing surface for fixing. When the mine car is connected, through the first fixing module and the second fixing module, the safety wire is tightly clamped between the first pressing surface and the second pressing surface, the safety wire can be effectively prevented from falling off in mine car operation, and thus the accidences, such as mine car falling road and rollover, caused due to the fact that the safety rope falls off are avoided; and the fixing device is simple in structure and convenient to operate, the time for fixing can be shortened, and working efficiency is improved.

The invention relates to an auxiliary supporting appliance, a single-wheel balance car, a bicycle and electric equipment. The auxiliary supporting appliance comprises a fixed frame and a supporting assembly; the fixed frame is fixed on equipment; and the supporting assembly is fixedly connected with the fixed frame so that the supporting assembly is fixedly connected with the equipment. As the supporting assembly is positioned between the ground and the equipment, the supporting assembly is extruded so that an elastic supporting piece in the supporting assembly is deformed to provide supporting force for the equipment when the equipment is inclined; therefore, the equipment can keep balance. In case that an inclination angle is continuously changed, the auxiliary supporting appliance can provide corresponding supporting forces with different sizes and continuously transitional values so that the equipment keeps balance at different inclination angles to avoid rollover.

The invention discloses a bump processing apparatus and method of an electric automobile. The apparatus comprises an X-direction acceleration transducer arranged on a battery casing for detecting an accelerated speed of the battery casing in the advancing direction of the electric automobile; a Y-direction acceleration transducer arranged on the battery casing for detecting an accelerated speed of the battery casing in a direction vertical to the advancing direction of the electric automobile; a gravity sensor arranged on the battery casing for detecting an inclination angle between the battery casing and a horizontal plane; an alarm apparatus used for emitting an alarm; and a controller connected with the X-direction acceleration transducer, the Y-direction acceleration transducer, the gravity sensor and the alarm apparatus for controlling the alarm apparatus to emit the alarm according to detection signals of the X-direction acceleration transducer, the Y-direction acceleration transducer and the gravity sensor. According to the invention, whether a bump and a rollover accident of the electric automobile occur can be detected, once there is a bump or rollover accident, the alarm can be timely given.

The invention discloses a coal mine underground rail wheel type high-altitude elevator, which relates to rail wheel type high-altitude lifting equipment in a coal mine underground roadway, and comprises a mining flat car, a shear fork lifting swing sliding frame, a double-piston-rod type sliding hydraulic cylinder, a working platform, a remote controller, an electric cabinet, a power supply, a hydraulic station and a claw type stabilizer, wherein the shear fork lifting, swinging and sliding frame is composed of a bottom base, a shear fork arm, a lifting hydraulic cylinder, a top base, a swinging and sliding seat, an ejector rod, a nut sleeve, a lead screw and a hydraulic motor; the claw type stabilizer is composed of a hydraulic cylinder, a left side fixing guide plate, a right side fixing guide plate, a rear connecting rod, a hinged guide pin shaft, a front connecting rod, a front clamping claw, a hinged fixing pin shaft and a rear clamping claw. The equipment can prevent the high-altitude elevator from rollover or overturning when the high-altitude elevator is in unbalance loading and located on a track of an inclined roadway, the operation platform is adjusted to be always kept in a horizontal state, meanwhile, the position of the operation platform in the width direction of the roadway is adjusted, the mechanization degree of installation of underground roadway top equipment and daily operation maintenance work is improved, and the working efficiency is improved. The labor intensity of operators is reduced, and the working efficiency is improved.
