Abstract
The utility model relates to a gas sampling probe transmission mechanism which comprises a driving device and a bearing guide rail, wherein the driving device is fixedly connected with a gas sampling probe; the two sides of the bearing guide rail are respectively provided with double guide chains; and the driving device is connected with the double guide chains by gears. The gas sampling probe transmission mechanism is provided with the double fixed guide chains, thus being less in maintenance; and a motor and the probe move back and forth together, so that the reliability is high. The gas sampling probe can automatically walk, and the transmission mechanism is driven to automatically exit from the gas sampling probe by the motor when a system has failure, so that the gas sampling probe is effectively prevented from being damaged.
Description
Technical field
The utility model relates to high-temperature gas sampling probe gear train, particularly, relates to the automatic travel mechanism of high-temperature gas sampling probe.
Background technology
Detect in high-temperature occasion (>=1200 ℃), what generally adopt is cycle down wet body sampling probe.But when the circulation cooling system breaks down, need to withdraw from gas sampling probe automatically, thereby effectively the blanket gas sampling probe is not damaged.Commonly used is the gas sampling probe gear train at present; The motor and speed reducer of this mechanism is fixed on the rear of spandrel girder, gas sampling probe be lifted on spandrel girder below, and be arranged on and walk to lead chain for single file on the guide rail; Moment is little, and the reliability of whole gear train is not high.
The utility model content
The purpose of the utility model is, a kind of high-temperature gas sampling probe gear train is provided, and is little to solve existing gear train driving torque, the technical matters that reliability is not high.
The technical scheme of the utility model is following:
A kind of gas sampling probe gear train comprises drive unit and load-bearing guide rail; Said drive unit is fixedly connected with gas sampling probe; Said load-bearing guide rail both sides are provided with two drag chains, and said drive unit is connected with said pair of drag chain through gear and walks along said load-bearing guide rail.
Said drive unit is positioned at the below of gas sampling probe.
Said drive unit comprises motor and by motor-driven gear, said gear and said pair of drag chain mesh.
Said drive unit comprises motor and speed reducer, and the output terminal of said motor is connected with the input of said reductor, on the output terminal of said reductor gear is installed, said gear and said pair of drag chain engagement.This gas sampling probe gear train comprises the weight-bearing activities wheel, and said drive unit is carried on the said load-bearing guide beam through this weight-bearing activities wheel.
This gas sampling probe gear train comprises position detecting device, this position detecting device be arranged on said load-bearing guide rail near.
The gas sampling probe gear train of the utility model is provided with two fixing guiding chains, and maintenance is little, and motor seesaws with probe together, and reliability is high.Gas sampling probe can be realized automatic walking, and system breaks down and relies on the motor drives gear train to withdraw from gas sampling probe automatically, thereby effectively the blanket gas sampling probe is not damaged.
Description of drawings
Fig. 1 a-1c is the synoptic diagram of the gas sampling probe gear train embodiment of the utility model;
Fig. 2 is the synoptic diagram of the two drag chains in Fig. 1 gas sampling probe gear train.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The principle that the gas sampling probe gear train utilization of the utility model is walked automatically and driven a vehicle drives the gas sampled sampling probe automatically and moves forward and backward, and the circulation cooling system failure realizes withdrawing from automatically gas sampling probe.
Shown in Fig. 1 a-1c, a kind of gas sampling probe gear train comprises drive unit 10 and load-bearing guide rail 1; Said drive unit 10 and gas sampling probe 6 are fixedly connected and are positioned at the below of gas sampling probe 6; Be provided with in load-bearing guide rail 1 both sides and be arranged with two drag chains 5 in parallel, said drive unit is connected with said pair of drag chain 5 through gear 7, and said drive unit 10 moves along load-bearing guide rail 1.Said drive unit 10 comprises motor 3 and gear 7, gear 7 and two drag chain 5 engagements.Certain said drive unit also can be to comprise motor 3 and reductor 4, and the output terminal of motor 3 is connected with the input end of reductor 4, and the output terminal of reductor 4 is connected with gear 7, gear 7 and two drag chain 5 engagements.When motor 3 driven gears 7 rotate like this,, drive unit 10 is moved around along load-bearing guide rail 1 through the engagement of gear 7 with two drag chains.This gas sampling probe gear train also comprises weight-bearing activities wheel 8, and said drive unit 10 is carried on the load-bearing guide rail 1 through this weight-bearing activities wheel 8, with the suspension that realizes whole gas sampling probe gear train with move.This gas sampling probe gear train also comprises position detecting device 9; This position detecting device 9 be arranged on load-bearing guide rail 1 near; When this gas sampling probe gear train arrives assigned address; Position detecting device 9 detects signal, can send stop instruction to motor, and motor 3 quits work or backward rotation.Motor 3 wherein, reductor 4 driven gears 7 and two drag chain 5 engagements make drive unit 10 move forward and backward along load-bearing guide rail 1, thereby realize driving gas sampling probe 6 synchronization-moving effects.When guide rail moved forward and backward, weight-bearing activities wheel 8 rolled on load-bearing guide rail 1 and passes through at drive unit 6.
What Fig. 2 showed is the schematic construction of the two drag chains in Fig. 1 gas sampling probe gear train, has shown two drag chains 5.
This gas sampling probe gear train is provided with two fixed guide chains, and maintenance is little, and motor and gas sampling probe seesaw together, and reliability is high.Gas sampling probe is walked automatically, and the cycle down system breaks down and relies on this gear train of driven by motor to withdraw from gas sampling probe automatically, thereby effectively the protection sampling is not damaged with probe.
Above-described embodiment is merely the technological thought and the characteristics of explanation the utility model; Its purpose is the content that makes those skilled in the art can understand the utility model and implements according to this; Can not limit the protection domain of the utility model according to this; The equalization of promptly being done with the spirit that the utility model was disclosed changes or derives, and must be encompassed in the protection domain of the utility model.
