Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, on support 1 surface level, be provided with guide rail 3 and motor 2 and be in transmission connection with motor 2, the screw rod 4 that be arranged in parallel with guide rail 3, on guide rail 3, slide and be provided with slide plate 12, being provided with nut 11 on slide plate 12 is in transmission connection with screw rod 4, nut 11 is the differential screw type of belt drive with screw rod 4 type of belt drive, on slide plate 12, be provided with excellent frame guide rail 8 and excellent frame motor 7 and be in transmission connection with excellent frame motor 7, the excellent frame screw rod 9 that be arranged in parallel with excellent frame guide rail 8, rod frame guide rail 8 direction and guide rail 3 be set the direction horizontal vertical is set, on excellent frame guide rail 8, slide and be provided with bar rack assembly 5, being provided with excellent frame nut 10 on bar rack assembly 5 is in transmission connection with excellent frame screw rod 9, rod frame nut 10 is the differential screw type of belt drive with excellent frame screw rod 9 type of belt drive, be provided with excellent frame cage keps assembly 6 on bar rack assembly 5, excellent frame pallet 13 adopts the drawer type unitized construction to be inserted in the excellent frame cage keps assembly 6; Hydrogen flame detector is fixedly mounted on the support 1, and control system adopts STD Industrial Control Computer Based Intelligent Control.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, thin layer rod 14 levels of launching to be inserted in the excellent frame pallet 13, excellent frame pallet 13 is put on the excellent frame cage keps assembly 6, drives bar rack assembly 5 by excellent frame motor 7, presses setting speed front and back on excellent frame guide rail 8 and moves; Motor 2 drives slide plate 12 and horizontally slips on guide rail 3 by setting speed, since excellent frame guide rail 8 direction and guide rail 3 be set the direction horizontal vertical is set, the motion summation of bar rack assembly 5 and slide plate 12, constituted the omnibearing movable of excellent frame cage keps assembly 6 on surface level, realized that hydrogen flame detector carries out comprehensive fixed point scanning to thin layer rod and detects.
The STD Industrial Control Computer has adopted open system architecture, modularization is the most outstanding characteristics in the STD bus design philosophy, its system forms the type that does not have fixing pattern, and provided a large amount of functional modules, needs according to instrumental function, can pass through selection and combination, promptly can be configured to be suitable for the enforcement control system of different controlling object, different operation scale process the kind and the quantity of template.According to the design of existing instrument, this mode now satisfies capacity requirement substantially, has fully reserved extending space simultaneously.Outstanding feature is: modular design, and system forms, revises and expands conveniently; Each intermodule is relatively independent, makes detection, debugging, troubleshooting simple, convenient and rapid; There is multiple functional template to have significantly reduced the hardware design workload for selecting for use; Can move the support software of several operation systems and system development in the system, use the Control Software development difficulty significantly to reduce.Therefore, be to select suitable standard functions template in the main hardware design effort of carrying out Control System Design with STD bus, and these templates are connected into required control device by STD bus.Digital quantity I/O template.Digital quantity I/O template is used to handle the input and output of switching signal, and its major function is filtering, level conversion, electrical isolation and power drive etc.Industrial switching signal commonly used have state, the pilot lamp of binary-coded decimal, counting and timing signal, various switches on and off, thyristor conducting and by the startup of, motor with stop or the like.These switching signals can link to each other with the CPU template through bus by digital quantity I/O template.
The slip screw transmission have the reduction of speed ratio of gear big, drive characteristics such as the strong and self-locking of load capacity.The reduction of speed ratio of gear is big: screw rod (or nut) rotates one to be changeed, and nut (or screw rod) moves a pitch (single thread).Because pitch is generally very little, thus under the very big situation of corner, can obtain the very little straight line amount of moving, can be greater than the driving-chain that shortens mechanism, thereby worm drive are simple in structure, compact, transmission accuracy height, stable working.Have boosting function: as long as to less input torque of driving link (screw rod), driven member can obtain bigger axial force output, so the worm drive carrying load ability is stronger.Can self-locking: when the angle of spiral during less than angle of friction, worm drive have self-locking action.Low, the quick abrasion of efficient: because this mechanical system rotating speed low (mm/min) is not so the sliding friction of spiral workplace can cause its transmission wearing and tearing.
The utility model is simple to operate:
A, get rod and the dress rod is complete operation (abroad have now instrument 4-5 action) with an action only all;
B, whole clubs are done in the middle of the process, have avoided artificial damage (existing instrument needs bimanualness, damages thin layer rod easily) abroad;
C, this instrument have automatic cleaning thin layer rod function, can observe the degree of purification (not establishing this function abroad) of thin layer rod during cleaning;
D, owing to adopted the stationary hydrogen flame detector, hydrogen flame detector need not be dug during the dress rod, so the collector of hydrogen flame detector apart from the non-displacement phenomenon, is therefore improving the analyzing and testing sensitivity of instrument, test proves can reach 10
-10(external instrument only reaches 10
-9).
