Push rod locking mechanism and hydraulic support

Abstract

The invention discloses a push rod locking mechanism and a hydraulic support. According to the push rod locking mechanism, the distance between the second ends of two bent rods on a supporting rod is adjusted, so that a push rod can be sleeved with a polygon formed by the supporting rod and the two bent rods; then the second ends of the two bent rods are fixed to the supporting rod through limiting assemblies, so that the push rod is locked by the supporting rod and the two bent rods and hoisted on a base; and the first ends of the two bent rods are hinged, so that the two bent rods rotate relative to each other, and then push rods of different types can be sleeved with the polygon formed by the supporting rod and the two bent rods. Thus, the push rod locking mechanism is high in applicability and attractive.

Description

technical field [0001] The invention belongs to the technical field of hydraulic supports, and in particular relates to a push rod locking mechanism and a hydraulic support. Background technique [0002] The hydraulic support is the main support equipment for the underground fully mechanized coal mining face. It mainly includes the top beam, the cover beam and the base. The element is an oil cylinder. In order to protect the oil cylinder during the transportation of the pushing device, the pushing device is generally lifted and fixed on the base. The usual solution is to pass the profile through the lifting ring on the push rod, and put the two ends on the front end of the base, or directly use The iron wire connects the push rod to the base, and the scheme of using the profile to pass through the lifting ring on the push rod often encounters that the push rod will touch the bridge when it is lifted, which may easily cause damage to the push rod, and for those without weldi...

Problems solved by technology

In order to protect the oil cylinder during the transportation of the pushing device, the pushing device is generally lifted and fixed on the base. The usual solution is to pass the profile through the lifting ring on the push rod, and put the two ends on the front end of the base, or directly use The iron wire connects the push rod to the base, and the scheme of using the profile to pass through the lifting ring on the push rod often encounters that the push rod will touch the bridge when it is lifted, which may easily cause damage to the push rod, and for those without welding rings The push rod is not suitable; and although the scheme of directly connecting the push rod and the base with iron wire is simple and economical, it is not beautiful and professional to bind the push rod with iron wire. Therefore, a suitable and beautiful push rod transport locking mechanism is urgently needed Research
