Background technology
It has been the technology of widespread usage that the full width of industrial processes detects at line sweep, used scanning support, what adopt is the form of the gauge fixed, be that it is only applicable on fixed rail distance or the paper machine less than its gauge, as patent documentation CN2508350Y disclosed a kind of " O " shape scanning support, in above traditional scanning detects, scanning support all is fixedly mounted on the equipment, its subject matter is to be only applicable to the paper machine of single gauge or to be used for paper machine less than its gauge, and for a paper mill, form by the paper machine of many different gauges mostly, need interim inline diagnosis to detect and in actual production, often run into, especially need tentative diagnosis between the new equipment limber up period or when the production problem takes place, press section water content detection such as paper machine, if every paper machine is equipped with such scanning support, like this for the cost of paper than higher.Develop a kind of scanning simple, that change with the paper machine gauge and put up a urgent problem.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of dismountable, sliceable and spacing scanning support can freely regulated scanning support.
The described scanning support of the utility model, it contains bar, bracing frame, hauling-chain frame, main System cabine, the sensor heads case of rolling that scanner is installed; The bar of described installation scanner is fixed on the bracing frame; The main transmission gear that rolls in the System cabine directly links to each other with drive motor; The bar that scanner is installed is formed by connecting by the multistage bar, and described connection is removable, on the two ends of track travel switch is installed, the to-and-fro movement that described travel switch may command master rolls System cabine; A sensor detection case rolls System cabine by web member with the master and links to each other; Described bracing frame has a retractor device, makes the extending or shortening of bracing frame.
Described bracing frame can be two bars, described bar can be circular, square or analogous shape, and described every bar has a retractor device, and described retractor device can be for being made up of two sections bars, one section freely stretches in another section bar, and makes bar fixing flexible by fixed pin.
The bar of described installation scanner can rotate around its center line, as bearing being installed by the bar two ends, described bearing fixing is on bracing frame, make installation scanner wheelwork also comprise a Weighting system for described main sweep frame, described Weighting system can rotate the bar that scanner is installed under its action of gravity, a fixed part that bar that scanner is installed is maintained static is arranged on the described bracing frame, and described fixed part can be screw or pin.
The bar multistage bar of described installation scanner connects can be for being threaded, also can connecting for joint, also can connecting for sleeve pipe.
What left and right sidesing supporting frame adopted is the pipe form, is the load spare of whole scanning support.
The parts of described Measurement and Control System are integrated in the control box, form control box; The repeatedly instrument that comprises input in the control box, parts such as programmable controller, display, industrial computer, field instrument distributor, on-the-spot travel switch controller.
Described hauling-chain frame can be to be fixed by the telescoping shoring column on both sides, drag chain just is positioned in the carriage, other all electric wires, cable and control line all place in the drag chain, so both can reduce the reciprocating wearing and tearing of electric wire, cable and control line, and also these lines can be sent to and carry out Stroke Control and operation control in the control box.
Adopt the utility model, scanning support is simple in structure, is out of shape for a short time, and measurement result is accurate; Owing to adopted multistage to be formed by connecting, thus go on the paper machine of different gauges since simple in structure be single-sweep, clean scanning detection head, safeguard simple; Measurement and Control System is integrated in the control box, and is easy to operate, and effectively reduces signal and disturb.
Embodiment
The utility model scanning support comprises and contains bar 1, bracing frame 2, hauling-chain frame 3, main System cabine 4, the sensor heads case 5 of rolling that scanner is installed; The bar 1 of described installation scanner is fixed on the bracing frame 2; The main transmission gear that rolls in the System cabine 4 directly links to each other with drive motor; The bar 1 that scanner is installed is formed by connecting by three sections bars, and described connection is removable, adopts hinge to connect, and bar 1 two ends that scanner is installed respectively are fixed with travel switch, and described travel switch may command master rolls System cabine 4 to-and-fro movements; A sensor detection case 5 rolls System cabine 4 by bolt with the master and links to each other; Described bracing frame 1 has a retractor device, makes the extending or shortening of bracing frame, and described retractor device is made up of two sections bars, and one section freely stretches in another section bar, and makes bar fixing flexible by fixed pin 6.The bar 1 of described installation scanner rotates around its center line, by the bar two ends bearing is installed, described bearing fixing is on bracing frame, described main sweep frame comprises that also makes the wheelwork 8 that the rotation of scanner bar is installed, described wheelwork is a Weighting system, described Weighting system can rotate the bar that scanner is installed under its action of gravity, a fixed part 7 that bar that scanner is installed is maintained static is arranged on the described bracing frame, and described fixed part is a pin.
What bracing frame 2 adopted is the pipe form, is the load spare of whole scanning support.The parts of described Measurement and Control System are integrated in the control box, form control box; The repeatedly instrument that comprises input in the control box, parts such as programmable controller, display, industrial computer, field instrument distributor, on-the-spot travel switch controller.Described hauling-chain frame can be to be fixed by the telescoping shoring column on both sides, and drag chain just is positioned in the carriage, and other all electric wires, cable and control line all place in the drag chain.
