Abstract
The utility model discloses a device for preventing cable abrasion in an endoscopic pipeline detection system. The device comprises a cable limiting device which is arranged at the wire outlet end of a cable rack and comprises four rollers, wherein two horizontal rollers are respectively arranged above and below a pulled-out cable; the other two vertical rollers are respectively arranged at the left side and the right side of the pulled-out cable; and the projections of the four rollers on a plane vertical to the pulled-out cable are #-shaped. The pulled-out cable is limited by the four rollers, so that the off-tracking of the cable is avoided. Rolling friction is formed among the rollers and the cable, so that the pulled-out cable can smoothly pass without blockage and scratching, a cable protecting layer is effectively protected, and the service life of the cable is prolonged.
Description
Technical field
The utility model relate to a kind of use on the cable trough of closed circuit TV pipe endoscopic detection system, can prevent cable pulling out with winding process in the device of card line, belong to the cable technology field.
Background technique
Closed circuit TV (Closed Circuit Television is called for short CCTV) pipe endoscopic detection system mainly forms (referring to Fig. 1) by master cpu, cable trough, crawl device, the several leading major part of shooting.In being carried out, peeps by large diameter pipeline when detecting, master cpu and cable trough are in the inspection shaft outside, crawl device is carrying camera, cable enters pipe interior and detects in tow, the effect of cable is to provide power supply to crawl device, camera and lighting set, and the picture signal of camera collection is sent to master cpu.
There is no rational outlet line device on cable trough due to traditional C CTV pipe endoscopic detection system, cable is drawn out or is wound up in process on cable tray and all can produce sliding friction with the wire outlet of cable trough, be easy to occur the phenomenon of card line, cable deviation, also can cause the cable sheath damage when serious, thereby affect the working life of cable.
The model utility content
The purpose of this utility model is the drawback for prior art, and the device that prevents cable abrasion in a kind of pipe endoscopic detection system that can effectively prevent the card line is provided, to extend the working life of cable.
Problem described in the utility model realizes with following technical proposals:
Prevent the device of cable abrasion in a kind of pipe endoscopic detection system, it comprises the cable limit stoper that is arranged on the cable trough outlet terminal, described cable limit stoper comprises four rolling, wherein two are horizontal roller and lay respectively at the above and below that is drawn out cable, two other is vertical roller and lay respectively at left side and the right side that is drawn out cable, and four rolling is perpendicular to being projected as the " # " font on the plane that is drawn out cable.
Prevent the device of cable abrasion in above-mentioned pipe endoscopic detection system, set up the metering Cable length device, described metering Cable length device is arranged on cable limit stoper one side; Described metering Cable length device is made of rice wheel and encoder, and the cable that is drawn out is by the input shaft rotation of rice wheel drive encoder, and the signal output part of described encoder is connected with master cpu through telecommunication cable.
Prevent the device of cable abrasion in above-mentioned pipe endoscopic detection system, described cable limit stoper arranges two, lays respectively at the place ahead and the rear of rice wheel.
It is spacing that cable limit stoper of the present utility model utilizes four rolling that the cable that is drawn out is carried out, and prevents cable deviation.Owing to being rolling friction between roller and cable, the cable that therefore is drawn out can pass through swimmingly, can not occur stuck and scratch phenomenon, has so just effectively protected cable sheath, thereby has extended the working life of cable.
What the metering Cable length device be used for to be measured cable emits length and then the distance of definite crawl device and pipeline opening.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of CCTV pipe endoscopic detection system;
Fig. 2 is structural representation of the present utility model.
In figure, each list of reference numerals is: 1, crawl device; 2, cable; 3, outlet line device; 4, cable tray; 5, cable trough; 6, encoder; 7, rice wheel; 8, roller.
Embodiment
Referring to Fig. 1, Fig. 2, the utility model is arranged on cable trough 5 outlet terminals, comprises two cable limit stoper and a metering Cable length device, is mainly to prevent cable card line when outlet.Each cable limit stoper comprises four rolling 8, four rolling 8 is perpendicular to being projected as the " # " font on the plane that is drawn out cable 2, cable 2 passes in the middle of this " # " font roller group, cable 2 is rolling friction with wire outlet like this, can avoid cable stuck phenomenon to occur or cable sheath sustains damage.
The outer rim of rice wheel 7 leans against on two cables 2 between the cable limit stoper, its output shaft is connected with the input shaft of encoder 6, when cable 2 motion, drive 7 rotations of rice wheel, rice wheel 7 drives encoder 6 rotations and counts, the output signal of encoder 6 is delivered to master cpu by telecommunication cable again, and the number of turns that master cpu rotates encoder 6 is converted into a meter number and is shown on screen.
Cable limit stoper in Fig. 2 should have two, they lay respectively at the place ahead and the rear of rice wheel 7, the cable limit stoper that is positioned at rice wheel 7 rears is because being blocked and can not see by encoder 6, so only drawn the cable limit stoper (comprising four rolling 8) in rice wheel 7 the place aheads in Fig. 2.From cable 2 axially, cable 2 only can be passed in space between the four rolling 8 of each cable limit stoper, when all directions drag cable 2 from the outside, position-limiting action due to roller group, can guarantee that cable passes in and out cable trough smoothly, and guarantee cable 2 and rice wheel 7 good contacts, can not affect the measuring accuracy of encoder 6; Owing to being rolling friction between cable 2 and roller 8, cable also can not be clamped, and therefore can effectively avoid the impaired of cable 2.
Claims (3)
1. prevent the device of cable abrasion in a pipe endoscopic detection system, it is characterized in that, it comprises the cable limit stoper that is arranged on cable trough (5) outlet terminal, described cable limit stoper comprises four rolling (8), described four rolling is divided into two groups, wherein two are horizontal roller and lay respectively at the above and below that is drawn out cable (2), two other is vertical roller and lay respectively at left side and the right side that is drawn out cable (2), and four rolling (8) is perpendicular to being projected as the " # " font on the plane that is drawn out cable (2).
2. prevent the device of cable abrasion in a kind of pipe endoscopic detection system according to claim 1, it is characterized in that, set up the metering Cable length device, described metering Cable length device is arranged on cable limit stoper one side; Described metering Cable length device is made of rice wheel (7) and encoder (6), and the cable that is drawn out (2) takes turns by rice the input shaft rotation that (7) drive encoder (6), and the signal output part of described encoder (6) is connected with master cpu through telecommunication cable.
