Abstract
The utility model relates to a positioning and locking device for a PCCP (prestressed concrete cylinder pipe) cathodic protection steel strip, which comprises a limiting clamp ring (1), an anchoring bolt (2), a limiting bolt (3), a limiting case (4), a sliding case (5), an eccentric latch (6), a bolt pin (7), a latch plate (8) and a counter weight (9). The limiting clamp ring (1) can be fixed onto a pipeline socket through the anchoring bolt (2), the limiting case (4) is welded onto the limiting clamp ring (1), the sliding case (5) is connected with the limiting case (4) through the limiting bolt (3), the eccentric latch (6) is fixed onto the sliding case (5) through the bolt pin (7), the latch plate (8) is welded onto the sliding case (5), and the counter weight (9) is fixed onto the eccentric latch (6). By means of the positioning and locking device, the steel strip can be locked in position to be linear during winding of prestressed steel wires on apipeline, protruding of the steel strip due to length and size deviation and intrinsic problems of materials can be avoided, steel strip materials are saved while the prestressed steel wires are powerfully protected, and the service life of the pipeline is prolonged.
Description
Technical field
The utility model relates to a kind of at Prestressed concrete cylinder pipe (PRESTRESSED CONCRETE CYLINDER PIPE, abbreviation: PCCP) twine in the compressor wire process, prevent cathodic protection steel band generation deflection or produce protruding device.
Background technology
At present; PCCP pipeline cathode protection band steel band and the connected mode of pipeline own are divided into two kinds, and a kind of is directly one section of steel band to be hung up at pipeline socket end, begins winding steel wire by duct bottom; Steel band is embedded in steel wire inside; And then with two ends hold with pipeline, jack panel is connected, this method very easily causes steel band in the process of winding steel wire, deflection to take place, waste material.Another kind is steel band to be fixed in advance through jockey pipeline holds, the jack panel two ends; Winding steel wire is embedded in steel wire inside with steel band again, and this method is owing to be predetermined fixed, and the steel band length dimension may not be very precisely; Can be during ending owing to steel band the long slightly or problem of its material own cause convexity; In the process of spraying steel wire cover, form hollowing, directly influence the service life of steel wire, cause pipeline to be scrapped.
Summary of the invention
The purpose of the utility model is to design a kind of PCCP cathodic protection steel band positioning and locking device; Can twine in the compressor wire process the steel band locking position at pipeline; Be straight line, and guarantee that steel band can not cause convexity because of length dimension deviation and the problem of material own.
The basic principle of PCCP cathodic protection steel band positioning and locking device is through spacing snap ring and anchor bolt this device to be fixed on pipeline socket end; Then the cathodic protection steel band is passed from latch plate and the two centre of eccentric latch; When steel band because latch plate and eccentric latch can in time be locked and prevented that the cathodic protection steel band from coming off during gravity sag; Steel band can freely move up under the effect that twines a power on the other hand, prevents that steel band is protruding.
PCCP cathodic protection steel band positioning and locking device basic structure is made up of spacing snap ring (1), anchor bolt (2), caging bolt (3), spacing casing (4), slip casing (5), eccentric latch (6), pin (7), latch plate (8), balancing weight (9); Spacing snap ring (1) can be fixed on the pipeline socket through anchor bolt (2); Spacing casing (4) is welded on the snap ring (1); Slip casing (5) links to each other with spacing casing (4) through caging bolt (3); Eccentric latch (6) is fixed on the slip casing (5) through pin (7), and latch plate (8) is welded on the slip casing (5), and balancing weight (9) is fixed on the eccentric latch (6).
The utility model can be implemented in pipeline preferably and twine in the compressor wire process the steel band locking position; Be straight line; And guarantee that steel band can not cause convexity because of length dimension deviation and the problem of material own; When having saved strip material strong protection compressor wire, strengthened pipeline service life.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.Form by spacing snap ring (1), anchor bolt (2), caging bolt (3), spacing casing (4), slip casing (5), eccentric latch (6), pin (7), latch plate (8), balancing weight (9), cathodic protection steel band (10), compressor wire (11).
Accompanying drawing 2 is the schematic top plan view of the utility model.Form by spacing snap ring (1), anchor bolt (2), caging bolt (3), spacing casing (4), slip casing (5), eccentric latch (6), pin (7), latch plate (8), cathodic protection steel band (10).
The specific embodiment
In the actual production use; At first spacing snap ring (1) is fixed on the pipeline socket through anchor bolt (2); With cathodic protection steel band (10) from inserting between eccentric latch (6) and the latch plate (8); Lower end and pipeline female end are fixed, and put down balancing weight (9) and make eccentric latch (6) and latch plate (8) step up cathodic protection steel band (10), begin to twine silk.In twining a process owing to twine the gravity that an active force is far longer than balancing weight (9); So cathodic protection steel band (10) can freely move up twining under the power effect; Treat that active force disappears; Eccentric latch (6) is self-return under balancing weight (9) effect again, steps up cathodic protection steel band (10) with latch plate (8) and guarantees that it no longer moves down, and finishes until twining silk.
Claims (1)
1.PCCP cathodic protection steel band positioning and locking device; It is characterized in that: form by spacing snap ring (1), anchor bolt (2), caging bolt (3), spacing casing (4), slip casing (5), eccentric latch (6), pin (7), latch plate (8), balancing weight (9); Spacing snap ring (1) can be fixed on the pipeline socket through anchor bolt (2); Spacing casing (4) is welded on the snap ring (1), and slip casing (5) links to each other with spacing casing (4) through caging bolt (3), and eccentric latch (6) is fixed on the slip casing (5) through pin (7); Latch plate (8) is welded on the slip casing (5), and balancing weight (9) is fixed on the eccentric latch (6).
