Movable guiding wheel anti-falling protection device

Abstract

The invention discloses a movable guiding wheel anti-falling protection device. The movable guiding wheel anti-falling protection device comprises a fixed base and a movable frame. A plurality of pin bases extending outwards from the fixed base in the width direction of the fixed base are arranged on the fixed base in the length direction of the fixed base, and intervals are formed among the pin bases. A plurality of sliding groove bases extending outwards in the width direction of the movable frame are arranged on the movable frame in the length direction of the movable frame, sliding grooves are formed in the sliding groove bases, and the movable frame is further provided with pin holes. The pin shafts penetrate the pin holes and the sliding grooves in the movable frame and the pin bases on the fixed base, so that the fixed base and the movable frame are connected together. The movable guiding wheel anti-falling protection device has the closing station and the opening station. In the closing station, the sliding groove bases are correspondingly arranged in the intervals among the pin bases, the included angle between the fixed base and the movable frame is basically zero, and a space is formed so as to contain a guiding wheel. In the opening station, the pin shafts move along the sliding grooves to enable the movable frame to be gradually separated from the fixed base, and the movable frame rotates by one angle around the pin shafts in the first direction.

Description

technical field [0001] The invention relates to a mechanical protection device, in particular to a protection device for a crane. Background technique [0002] Since the bridge crane will generate lateral force during operation, this lateral force will cause the bridge crane to deviate. In order to prevent the bridge crane from deviating, guide wheels will be installed on both sides of the track where the bridge crane travels. However, repeated alternating lateral forces between the guide wheel and the track often cause the flange bolts at the bottom of the guide wheel to break and fall, and in severe cases, even cause the shaft of the guide wheel to break and cause it to fall from a high altitude, thereby causing Serious security incident. At present, in order to prevent the guide wheel from falling from a high place, a guide wheel protection frame is usually installed outside the guide wheel.

Problems solved by technology

However, during the installation or removal process, high-altitude hot work will cause sparks to fall, which poses a great safety hazard to the equipment and products on the ground

At the same time, the entire operation process takes a long time, and the efficiency of installation and removal is low
