The collar of FIG. 1 for CPT 16 comprises upper 2 and lower 3 half-hicks, lever 4 made according to FIG. 6, the locking mechanism embodied in FIG. 2 and the locking mechanism configured in FIG. 3

The upper half-pipe 2, made according to FIG. 7, includes an eyelet 21 with a hole for mounting the lever 4 on the upper half-hose 2 and the eye 23 with an opening for the axle-connector 13, which in turn provides a movable connection between the upper 2 and lower 3 half-sleeves among themselves on the flat surface of the connector 24. In the upper half-hose 2, a groove 22 (see FIG. 7) is made to accommodate a sealing material (not shown in the drawings).

The lower half of the joint 3, made according to FIG. 8, contains a recess of a cylindrical shape 25, made according to the dimensions of the axis of the contactor 14, and an eyelet 26 with a hole for the axis of the connector 13, which in turn provides a movable connection of the upper 2 and lower 3 half-sleeves among themselves along the flat surface of the connector 24. In the lower the half-hose 3 has a groove 22 (see FIG. 8) for accommodating a sealing material (not shown in the drawings).

The locking mechanism made in FIG. 1, 2, 6, 7 and 8 and movably connected to the lever 4 by means of the second axis of the fastening 9 is a structure consisting of a fastening plate 6 with through holes for fastening the axis of the locking mechanism 14 and the second axis of the fastening 9 of the fastening plate 6 to lever 4, as well as from the plate of the lever 5 with a blind (non-through) hole for the “tongue” 29 of the clamp 8, as well as through holes for fastening the axis - contactor 14 and for the second axis of fastening 9 of the mounting plate 6 to the lever 4. Due to the offset of the axis -locking device 14, the shape of the lever 4 and the top 2 and the lower 3 half-sleeves, the eccentricity necessary for assembling-disassembling the collar is formed, with input-output from the engagement of the 14 mm axis of the contactor into / from the recess of the cylindrical form 25 and closing-opening on the surface of the connector 24 of the collapsible connection, while moving the upper 2 and lower 3 half joints is carried out using the axis of the connector 13 of FIG. four.

The locking mechanism of FIG. 1 and 3 and movably connected with a locking mechanism, a lever 4 and an upper semi-hose 2, consists of a clamp 8, which is a stepped shaft, made in FIG. 9, with a cylindrical surface 27 on which the removable shank 11 is mounted, a shoulder for the stop 28 of the spring 7 and a tongue 29 of the retainer 8 of a rectangular shape in cross section and containing a bevel at the end to ensure the locking mechanism is closed in normal operation. Additionally, the locking mechanism consists of the guide sleeve 10, the shank 11 and the housing 12 of the latch. The shank 11 is removable and is a cylindrical sleeve with grooves for installing a key and an internal cylindrical surface intended for detachable connection, for example, a threaded one with a counter surface in the form of a thread 27 on the retainer 8. Guiding sleeve 10 along which reciprocating movement the latch 8 when opening and closing the locking mechanism, made according to FIG. 3, is a stepped cylindrical sleeve with a threaded connection or another collapsible connection with the lever 4 and the housing 12 of the latch 8, which is a cylindrical sleeve with an internal stepped transition separating the shank 11 of the latch 8 from the clamping spring 7, providing the return movement of the latch at a distance required to close the locking mechanism, when mounting the collar modernized on the CPT, with the movement of the “tongue” of the retainer 29 into the blind (non-through) hole in the plate of the lever 5 ensure the possibility of closing, locking and opening the locking mechanism spontaneously when mounting the clamp on the collapsible conduit.

The lever 4, made according to FIG. 6, movably connected to the upper half-hitch by means of the first axis of fastening 1, is a figured L-shaped plate in which three through holes 18, 19, 20 are made, so the hole 18 is intended for mounting the lever 4 on the upper half-horn 2, with the first axis of the fastening 1, the hole 20 is intended for fastening the plate of the lever 5 and the fastening plate 6, which are part of the locking mechanism, and the hole 19 is intended for the installation of the guide sleeve 10 of the locking mechanism. In addition, the lever 4 is made shaped ledge 17, designed to protect the hands of the operator from pinching lever 4 when performing work on the Assembly and disassembly of the CPT in the production of emergency restoration and repair work on the main pipelines.

The work of the claimed clamp for CPT as follows. To ensure the assembly of CPT 16 with a clamp for CPT, two sections of CPT16 are placed in a joint on a flat surface butt-to-end, while around the circumference a rubber sealing ring is put on them (not shown in the drawings).

1) Laying of CPT sections is carried out with provision of a gap between the lower edge of CPT 16 and the ground so that it is possible to place the lower half-slide 3 under CPT 16 at the place of its connection.

2) After placing the lower half-clamp 3 under the joint of the CPT 16 connection, the upper half-clamp 2 by means of the lever 4, the plate 5 of the lever and the fixing plate 6 and the first axis of attachment 1 of the lever 4 on the return half-clamp 2 is superimposed on the joint of the sections CPT 16 in such a way that a tight fit of the semi-cylindrical surface 22 to the junction of the CPT section 16, and the upper and lower half-sleeves 2 and 3, respectively, are tightly attached to each other along the surface of the connector 24.

3) Next, using the lever 4, due to the fact that it is mounted on the upper semi-valve 2 with eccentricity, the locking mechanism (formed by the plate 5 of the lever 4 and the fixing plate 6, as well as the second axis of attachment 9 and the locking axle 14 of the locking mechanism due to additional connection with the upper semi-hose 2 through the eyelet 21) is moved so that the axis-contactor 14 is located in the recess of the cylindrical shape 25 of the lower semi-valve 3, while the locking mechanism automatically works. When this latch 8 together with the shank 11 under the action of the clamping spring 7 of the locking mechanism moves longitudinally in the guide sleeve 10 and the housing 12 of the clamp 8 to fully straighten the clamping spring 7, while the "tongue" 29 of the clamp 8 moves into a blind hole in the plate 6 and the locking mechanism is moved to the closed position.

4) Control the completion of fixing the clamp on the CPT 16 by using the lever 4 by touching the protrusion 17 of the outer surface of the upper half-clamp 2, while the protrusion 17 protects the hands of the operator from being pinched during assembly and disassembly of the clamp on the CPT.

5) To open and disassemble the collar with CPT 16, a special tool (key) is inserted into the grooves on the shank 11 of the retainer 8, which, being engaged with it, provides the ability to move the retainer 8 in the housing 12 and the guide sleeve 10 by compressing the pressure spring 7 .

6) After the compression spring 7 is fully compressed and the tongue 29 of the clamp 8 moves out of the mounting plate 6 into the guide sleeve 10, the locking mechanism is moved to the open position, then the operator moves the locking axle 14 of the locking mechanism 14 by moving the lever 4 from engagement with the recess of the cylindrical shape 25 of the lower half-clutch 3.

7) After opening the locking mechanism, the collar opens along the surface of the connector 24 with the lever 4, and the plate of the lever 5 and the fastening plate 6 rotate around the second axis of the fastening 9 in such a way as to rotate the semi-clamp 2 around the axis-connector 13 and remove the collar with CPT sixteen.

The use of the claimed clamp for CPT allows you to ensure a reliable and tight connection of CPT in the production of emergency repair and repair work on trunk pipelines without using a bolt connection used to connect two semi-clamps at the mounting location of the fasteners on existing designs of clamps and devices.

At the same time, when two semi-cranks are connected in the closed position by means of the fixing mechanism, they are automatically fixed in the closed position, which reduces the likelihood of abnormal disclosure and leakage of the oil or oil product. Opening of the claimed clamp is carried out in a strictly controlled way, using a special key, which causes the retainer 8 to be in the "open" position and allows the opening of the locking mechanism using the lever 4.
