The application relates to the technical field of bridge construction equipment, in particular to a prefabricated and assembled rhombic hanging basket and a mounting method thereof. The rhombic hanging basket comprises a main truss system, a walking system, a bottom basket platform, a suspension system and a composite anchoring system. The mounting based on the rhombic hanging basket comprises the following steps: prefabricating a foldable rhombic truss; using a hoisting device to pull the truss to unfold and pin shaft locking; installing a walking system and other components, using multiple frequency conversion winches to cooperate with displacement sensors, and using a synchronous deviation control algorithm to hoist the bottom basket platform as a whole. In the hanging basket, the rhombic truss can be folded and unfolded, the convenience of transporting and installing the hanging basket on site and putting into construction is improved, the walking system and the composite anchoring system are matched, the efficiency of moving the hanging basket is improved, the automatic synchronous control technology solves the hoisting control problem of the bottom basket under complex environment, the construction efficiency and safety of the hanging basket as a whole are improved, and the risk of high-altitude operation is reduced.

The application provides a remote control method and device for a high-pressure valve for fracturing, which comprises the following steps: acquiring a valve state and fracturing construction data; determining a fracturing construction state based on the fracturing construction data; when the fracturing construction state is a normal state and an operation instruction is received, adjusting the valve state in response to the operation instruction; the operation instruction is generated by an operator based on the fracturing construction data; when the fracturing construction state is an abnormal state, prohibiting valve operation and determining an abnormal type according to the valve state and / or the fracturing construction state. The fracturing construction state is determined based on the fracturing construction data, and the remote operation instruction is executed in the normal state to control the valve state, the valve operation is prohibited in the abnormal state, the construction risk caused by improper operation is avoided, and the abnormal type can be determined to provide timely abnormal suggestions for the operator.

The invention discloses a non-welding photovoltaic support and application thereof, and relates to the technical field of photovoltaic supports. Comprising a pile foundation, a front stand column, a rear stand column, a plurality of hoops, a cross arm, a front inclined strut, a rear inclined strut and an inclined beam. Wherein the hoops are arranged on the pile foundation in a sleeving mode at intervals, the cross arm is located above the hoops and located at the top of the pile foundation, and the cross arm and the two ends of each hoop are connected with the front stand column and the rear stand column correspondingly; one ends of the front inclined strut and the rear inclined strut are respectively connected with two ends of the inclined beam, the other ends are respectively connected with two ends of the lowermost hoop, and the middle part of the inclined beam is respectively connected with the top ends of the front upright post and the rear upright post; all the assemblies are detachably connected through preset connecting holes and bolt structures. The defects of an existing welding process are overcome, fireless, rapid and adjustable connection of the support and the pile foundation is achieved through modular mechanical connection design, the fireless construction requirements of special scenes are met, and the construction efficiency and later adjustability are improved.
