Description
Technical field
The utility model relates to a kind of industrial endoscope flexible pipe intervening equipment, particularly a kind of flexible pipe propulsive mechanism.
Background technology
Using a large amount of tiny pipelines in modern industrial and agricultural production and the daily life, as the industrial pipeline of oil, chemical industry, nuclear industry, refrigeration industry and gas piping etc., defectives such as burn into crackle, incrustation and mechanical damage can appear after these pipeline long-term works, for guaranteeing safety in production, must carry out prophylactic repair to tiny pipeline.At present, industrial endoscope remains one of the most frequently used method of pipe detection.
In the medical field, the endoscope diagnosis art is the important means of minimally invasive surgery, and the diagnosis and the treatment of focus had important role.With the colon cancer is example, and it is that the incidence of disease is listed as deputy malignant tumour in the industrialized country, and wherein 90% colon cancer is to be come by optimum polyp development, theoretically, utilizes endoscope to find and excision in all can diagnosing in early days.Endoscope is widely used in medical circle with the stability of its performance, the reliability of technology, the systematicness of kind, the small-sized property of device, the convenience of use and many advantages such as acceptability of the ratio of performance to price.
But all there are the defective of self in industrial endoscope and medical endoscope.Under the baroque situation of industrial pipeline, may cause endoscope to get involved; The enteron aisle structure is complicated more, there is the many places bend, only to be inserted into the depths not a duck soup to endoscope smoothly with feel, when endoscope slides in cavity organization, the cavity wall is produced pressure, might cause the inside of human body soft tissue to abrade and pull, in case this pressure surpasses certain threshold value, also can cause tissue damaged, cause the generation of malpractice.
At present, the such flexible pipe of similar endoscope is got involved all by artificial propelling, for improving the defective in the intervention procedure, is necessary to improve the degree of intelligence of intervention.For example, at the flexible pipe head microminiature sensor is installed, that realizes flexible pipe initiatively keeps away barrier etc.Realize similar intellectuality, must at first realize the automatic intervention of flexible pipe.
The purpose of this utility model is to provide a kind of automation equipment that can realize that flexible pipe advances, can realize the most basic action in the flexible pipe intervention procedure, as advances, retreats and rotation etc.
The utility model content
The purpose of this utility model is to provide a kind of flexible pipe propulsive mechanism, can realize automatically advancing, retreating in the flexible pipe intervention procedure and the most basic action such as rotation.
For achieving the above object, the utility model adopts following technical proposals:
A kind of flexible pipe propulsive mechanism, comprise a fixed support, it is characterized in that settling in the fixed support one by stepper motor through gear-driven revolution framework, settle the fixed clamp hand of a clamping flexible pipe and one by the mobile clamping hand of stepper motor in the revolution framework, and make flexible pipe center line and revolution framework central lines through the bolt and nut transmission.
The structure of above-mentioned revolution framework is: left rotation and right rotation body and a gear wheel are linked into an integrated entity by 3-6 root axial links; Gear wheel and a pinion, pinion wheel is fixed on the output shaft of stepper motor; The left rotation and right rotation body is respectively by three on the mounting and fixing bracket biside plate circumferential uniform little bearing rotating supports.
Above-mentioned fixed clamp hand fixed in position is inner on the left side of revolution framework; Mobile clamping hand and nut and a mobile web joint are fixed into one, this mobile web joint has the guide rail of the stationary platform in a slide block and one the revolution framework to be slidingly matched, and installs on the stationary platform that stepper motor and screw rod connect with the stepper motor output shaft and revolves with nut and to join.
Scrambler is equipped with in above-mentioned support bracket fastened left side.
The utility model compared with prior art, have following conspicuous characteristics and advantage: the revolution framework that has step motor drive to rotate in the utility model, can make the flexible pipe rotation, in the revolution framework, the fixed clamp hand is housed, flexible pipe is advanced or retreat, thus the elemental motion that can realize automatically that flexible pipe gets involved.Simple in structure, the reliable operation of the utility model, easy to use, the flexible pipe that applies to industrial endoscope and medical endoscope is got involved.
Description of drawings
Fig. 1 is the structural perspective of an embodiment of the present utility model.
Embodiment
A preferred embodiment of the present utility model is: referring to accompanying drawing, this flexible pipe propulsive mechanism includes a fixed support 9, settle one in the fixed support 9 by the revolution framework 4 of stepper motor 13 through gear 12,3 transmissions, settle the fixed clamp hand 16 of a clamping flexible pipe 8 and one by the mobile clamping hand 2 of stepper motor 10 in the revolution framework 4, and make flexible pipe 8 center lines and revolution framework 4 central lines through 14 transmissions of screw rod 15 nuts.The structure of above-mentioned revolution framework 4 is: 1,5 and gear wheels 3 of left rotation and right rotation body are linked into an integrated entity by 3-6 root axial links; Gear wheel 3 and pinion wheel 12 engagements, pinion wheel 12 is fixed on the output shaft of stepper motor 13; Left rotation and right rotation body 1,5 is respectively by three on mounting and fixing bracket 9 biside plates 7 circumferential uniform little bearing 6 rotating supports.Above-mentioned fixed clamp hand 16 fixed in position are inner on the left side of revolution framework 4; Mobile clamping hand 2 and nut 14 and a mobile web joint are fixed into one, this mobile web joint has the guide rail 18 of the stationary platform 11 in a slide block and one the revolution framework 4 to be slidingly matched, and installs on the stationary platform 11 that stepper motor 10 and screw rod 15 connect with stepper motor 10 output shafts and revolves with nut 14 and to join.Scrambler 17 is equipped with in the left side of above-mentioned fixed support 9.
The course of work of this flexible pipe propulsive mechanism is as follows: before starting working, make the endoscope flexible pipe pass two clamping hands 2,6 earlier, be placed on the central authorities of two clamping hands 2,6.During original state, mobile clamping hand 2 clamps endoscope flexible pipe 8 and advances endoscope flexible pipe 8 by 14 transmissions of screw mandrel 15 nuts, and fixed clamp hand 16 is in relaxation state; After mobile clamping hand 2 moved to the rail plate extreme position, fixed clamp hand 16 clamped endoscope flexible pipe 8, and mobile clamping hand 2 loosens and retreats into initial position, prepares next workflow.In the process that advances and retreat, can make endoscope flexible pipe 8, satisfy the action request that endoscope is got involved around the rotation of flexible pipe 8 centers.In the intervention procedure, measure the length that scope is got involved in real time by external scrambler 17; By the micro pressure sensor of installing on the scope shank, measure the resistance between endoscope shank and the enteron aisle chamber wall, and feed back to intervention mechanism, the direction of adjustment intervention power, intervention speed and rotation, angle etc.; By on mobile clamping hand 2, sliding feeling sensor being installed, cooperate suitable physical construction, be used to measure intervention power size.
