Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail。It should be noted that when not conflicting, embodiments herein and the feature in embodiment can be mutually combined。

As it is shown in figure 1, chain type transmission structure includes the actuating device 11, travelling car 12 and two optical axises 13 that are arranged on a fixed mount；Article two, optical axis 13 is parallel longitudinal is arranged on below actuating device 11 and is fixed on fixed mount；As shown in Figure 2, the first sprocket wheel 114 that the driven gear 113 that the driving gear 112 that actuating device 11 includes motor 111, be arranged on motor 111 axle engages with driving gear 112 is connected by axle with driven gear 113, driven the second sprocket wheel 116 and clutch operating handle 117 that rotate by chain 115, clutch operating handle 117 is arranged on the downside of driven gear, driven gear is made to disengage with driving gear by pulling clutch handle, manually probe sheath is exited, facilitate on-site maintenance and debugging；Specifically, motor 111 selects totally-enclosed reversible gear to slow down, and is greatly improved the safety and reliability of whole system；Being provided with back-moving spring 118 between driven gear and clutch handle, when operating handle 117 when loosening the clutch, driven gear resets under the effect of spring 118, again meshes together with driving gear。

As shown in Figure 3, travelling car 12 includes vehicle frame 121, four rolling 122 and dust-proof scrapes sweeping device 123, vehicle frame 121 is provided with two parallel longitudinal upper fixing bars and lower fixing bar, upper fixing bar and lower fixing bar are coated with two rollers 122 respectively, in the middle part of each roller 122, are all formed with, along sidewall circumferencial direction, the v-depression that groove footpath adapts with optical axis 13 external diameter；Travelling car 12 is installed on two optical axises 13 by roller 122 and can be moved back and forth (now optical axis 13 is perpendicular to upper fixing bar and lower fixing bar) at optical axis 13；Dust-proof sweeping device 123 of scraping is four, being separately positioned on the both sides being coated with optical axis of vehicle frame 121, when making travelling car 12 move back and forth on optical axis 13, each dust-proof sweeping device of scraping can both contact with optical axis 13, optical axis is swept dedusting, makes travelling car 12 in the without hindrance movement of optical axis 13。

Shown in comparison Fig. 1, link between travelling car 12 with chain 115, make travelling car 12 can move back and forth on optical axis 13 with chain 115 reciprocating rotation；Specifically, being provided with contiguous block at travelling car 12 top, contiguous block end face is provided with groove, is provided with the sliding shoe reciprocatingly slided along groove, and end, groove one end is provided with the fixed block being fixed as one with contiguous block in groove；In one section (namely contiguous with contiguous block one section) that chain 115 is positioned below separated, and chain 115 one end is fixed on fixed block, the other end is fixed on sliding shoe, the jackscrew of fastener chain it is provided with in the junction of chain 115 with sliding shoe, for regulating the elasticity of chain 115 by adjusting sliding shoe position in contiguous block groove, fix with jackscrew after having adjusted, to ensure chain normal rotation on sprocket wheel, it is prevented that chain skids。

When chain type transmission mechanism and high-temperature probe 2 with the use of time, for ensureing that high-temperature probe 2 can be properly inserted precalculated position in stove, fixed mount both sides ad-hoc location at chain device 11 is respectively arranged with front limit sensor and rear limit sensors, chain 115 is provided with sensor sensing sheet, when high-temperature probe protective jacket inserts in stove, the sensor sensing sheet being arranged on chain 115 moves with chain 115, and produces relative displacement between front limit sensor；When sensing chip moves to front limit sensor, sensor sends signal, controls motor 111 and stops operating, and now, high-temperature probe 2 is inserted in stove precalculated position；Equally, when outside high-temperature probe 2 retreats to stove, the sensor sensing sheet on chain 115 moves with chain 115, and produces relative displacement between rear limit sensors；When sensing chip moves to rear limit sensors, sensor sends signal control motor 111 and stops operating, and now, high-temperature probe 2 retreats to the outer precalculated position of stove。Wherein, the actual displacement decision that ad-hoc location enters in stove according to high-temperature probe time actually used 2 or exits in stove。
