A copper and copper alloy cast ingot crossing saw cutting production line comprises an ingot turning machine, a feeding roller way, a saw cutting machine and a material storage table, the ingot turning machine, the feeding roller way and the saw cutting machine are sequentially arranged in a cast ingot casting workshop, the material storage table is arranged in a rolling machining workshop, a rail is arranged between the saw cutting machine and the material storage table, and a crossing roller way trolley is movably arranged on the rail; a material storage pit is arranged adjacent to the ingot turning machine, and a material storage frame is arranged in the material storage pit; the cast ingots are temporarily stored on the storage rack in a vertical state, so that the length space occupied by horizontal placement and storage of the cast ingots is shortened; the ingot turning machine turns the ingot in the vertical state into the horizontal state, the operation that a crown block lifts the ingot to be horizontally placed in a temporary rough ingot storage area in the past is omitted, the ingot after saw cutting machining can be automatically moved to the crossing roller way trolley to be transported, the operation that the ingot is lifted to an electric flat car is completely omitted, and the production efficiency is improved. Therefore, the hoisting safety and the production efficiency in the cast ingot sawing process are greatly improved.

The present application aims to provide a kind of narrow space bridge cable push-pull tensioning method, comprising the following steps: A, two groups or more than jack are provided between working anchor and tool anchor, each group of jack is evenly arranged, so that when it pushes tool anchor, tool anchor is uniformly stressed;B, intelligent oil pump controls the oil pressure of each group of jack, so that it remains consistent, and simultaneously push tool anchor, and the steel strand is tensioned, when jack pushes to reach the stroke position, anchor nut of working anchor is locked;C, intelligent oil pump returns oil, and tool anchor returns initial position;D, repeat steps A-C, until the cable force reaches the design requirement.The present application aims to provide a kind of narrow space bridge cable push-pull tensioning method, which can well meet the steel strand tensioning demand in narrow space, and the tensioning process is stable, without damaging steel strand twist angle, to ensure tensioning effect.

The bag making equipment comprises a film releasing mechanism, a roller film feeding mechanism, a film pulling mechanism, a bag making welding area, a conveying line and a pipe opening welding mechanism, the film releasing mechanism, the roller film feeding mechanism, the bag making welding area and the pipe opening welding mechanism are sequentially arranged, and the film pulling mechanism and the conveying line are arranged on the same side of the bag making welding area. The film drawing mechanism comprises a film drawing head, a linear drive and an avoiding drive, and the linear drive and the avoiding drive are used for driving the film drawing head to reciprocate at the two ends of the bag making welding area; the bag making, filling and sealing system comprises the bag making equipment, the conveying line is a circulating conveying line, and a pipe opening welding mechanism, a waste edge cutting station, a bag transferring and reversing station, a filling station, a sealing station and a bag discharging station are sequentially arranged on the conveying line. The mounting distance is shortened, the problems that the longer the film feeding distance is, the more likely to generate film falling faults and film feeding deviation are solved, and the problems of low stability and qualified rate caused by the problems are solved.

The invention provides a lifting appliance heavy hammer limiting device. The lifting appliance heavy hammer limiting device comprises a triggering mechanism, a heavy hammer mechanism, a platform, a guide mechanism, an anti-swing mechanism, a height detector and a lifting appliance. The trigger mechanism is fixed on a platform of the crane, the guide mechanism is used for guiding the heavy hammer mechanism, the anti-swing mechanism is connected with the guide mechanism and the platform, the height detector is fixed at the lower end of the guide mechanism, and the lifting appliance is positioned below the device; a spring is arranged in the triggering mechanism and the triggering speed is increased through elastic force; the guide mechanism can enable the counter weight mechanism to accurately trigger the limit switch; the anti-swing mechanism prevents the guide mechanism from swinging and has an anti-falling function; the height detector is provided with an early warning value, when the height of the lifting appliance reaches the early warning value, the limiting switch can be triggered, the lifting power source is disconnected, and the lifting appliance is prevented from rushing against the platform. The problems that under the working conditions of high lifting height, large wind load and vibration, a traction steel wire is prone to being wound, an ejector rod is prone to being clamped, a device falls to hurt people, and the response is slow are solved, and the lifting appliance is prevented from impacting the top platform rapidly, effectively and accurately.

A switch belongs to the technical field of low-voltage apparatuses. Comprising a shell which forms accommodating spaces which are isolated at intervals; the contact system comprises a static contact assembly fixedly arranged in the accommodating space and a moving contact assembly rotatably arranged in the accommodating space, and the moving contact assembly swings in the horizontal direction relative to the static contact assembly to realize connection or disconnection of a switch; the electromagnetic operating mechanism comprises a fixed iron core and a movable iron core, the movable iron core is arranged at the position corresponding to the fixed iron core and can swing or translate in the horizontal direction, the movable iron core and the fixed iron core are attracted through excitation of an electromagnetic coil arranged in the fixed iron core, and the movable iron core drives the movable contact assembly to make contact with the static contact assembly so that the switch can be switched on. The utility model has the advantages that the length space of the switch in the horizontal direction is shortened, the miniaturization requirement is met, the anti-vibration performance is prevented from being affected due to the fact that the distance between the mass center of the movable iron core and the rotation center is long, and the situation that the contact rebounds and falls back in the opening process is avoided.
