Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

A clamp based on wedge block realization installation comprises two sets of mutually butted sleeve pipes 1 and chucks 2, the specific structure is that the chucks 2 are positioned between the sleeve pipes 1, the sleeve pipes 1 and the chucks 2 are of an integral structure formed by one-time casting, the axial cross section of the integral structure is of a transverse T-shaped structure, the two chucks 2 are in interference soft sealing connection through sealing rings 3, the middle parts of the sleeve pipes 1, the chucks 2 and the sealing rings 3 form a circular passage integrally, the outer ring side of the chucks 2 is sleeved with clamping clips of two arc-shaped structures, the two clamping clips are distributed up and down and are respectively a first clamping clip 4 and a second clamping clip 5, the two ends of the first clamping clip 4 are connected with the two ends of the second clamping clip 5 through wedge blocks 6 and clamping springs 7, the two ends of the first clamping clip 4 are provided with wedge grooves 8 and clamping rings 9, the tail end of the second clamping clip 5 is provided with a wedge groove 8, the wedge block 6 is embedded into the wedge groove 8 and is matched with the wedge groove 8, and the clamp spring 7 is located between the wedge block 6 and the clamp ring 9.

The radial section of the profile of the clamping arc-shaped structure is of an n-shaped structure, and the two chucks 2 are embedded into the n-shaped structure.

The chuck 2 is in an annular disc-shaped structure, and the thickness of the chuck 2 is gradually increased from the edge to the middle part

The both ends of first clamping 4 are equipped with abaculus 10, abaculus 10 with first clamping 4 is one shot casting fashioned overall structure, 5 both ends of second clamping are equipped with the caulking groove 11 of "U" shape structure, caulking groove 11 with second clamping 5 is one shot casting fashioned overall structure, abaculus 10 embedding in caulking groove 11, two voussoir 6 is followed the outside of "U" shape structure of caulking groove 11 runs through in opposite directions the keyway 8 and the embedding of keyway 11 lateral wall in the keyway 8 of abaculus 10.

The clamp spring 7 is of a C-shaped structure, a cut angle 12 is formed in the outer edge of the clamp ring 9, the inner diameter of the clamp spring 7 is larger than the maximum radial section of the wedge block 6 in an uncompressed and unstretched state in a normal state, and the outer diameter of the clamp spring 7 is larger than the inner diameter of the clamp ring 9.

The snap ring 9 is located the "U" shape structure left and right sides of caulking groove 11, it is specific, the outer loop side of snap ring 9 with 8 notches of wedge groove agree with on the caulking groove 11 mutually, the internal diameter of snap ring 9 is greater than the biggest radial cross-section of voussoir 6, snap ring 9 with caulking groove 11 is one shot casting fashioned overall structure.

during installation, the two sleeve pipes 1 which are used for establishing a river are respectively sleeved on two pipelines with connection, then are butted and connected through a first clamp 4 and a second clamp 5, and the installation steps are installation steps of a traditional hoop.

After the installation, the insert 10 and the caulking groove 11 of the first clip 4 and the second clip 5 are inserted into each other, and then four wedges 6 and snap rings 7 are required to complete the installation, and taking the installation of one wedge 6 as an example, the wedge 6 is inserted into the wedge groove 8 of the caulking groove 11 from the outside of the caulking groove 11, and after the wedge 6 penetrates the wedge groove 8, the wedge is further inserted into the wedge groove 8 of the wedge 10.

In the above process, the interfaces of the two wedge grooves 8 are not completely coupled initially, but are of an area sufficient to allow the foremost end of the wedge 6 to pass through, gradually coupling the two wedge grooves 8 due to the pressing of the inclined surfaces of the wedge 6 against the inclined surfaces of the wedge grooves 8, meanwhile, based on the gradual insertion and embedding of the embedded block 10 and the embedded groove 11, the first clamp 4 and the second clamp 5 can further approach to press the two sleeves and the sealing ring, and the inner arc sides of the first clamp 4 and the second clamp 5 can continuously extrude the sleeve 1, because the chuck 2 of the sleeve is in an annular disc-shaped structure, the thickness of the chuck 2 is increased gradually from the edge to the middle, the tightness of the first clamp 4 and the sleeve 1 and the tightness of the second clamp 5 and the sleeve 1 are increased, and the tightness of the two cutting sleeves 1 to the interface is also increased.

because the reset elasticity of sealing ring 3 and the gravity of each work piece itself can extrude voussoir 6 and have the trend of holding in the palm out wedge groove 8, so still need imbed jump ring 7 into wedge groove 8, because the corner cut 12 design of snap ring 9 need not earlier compression jump ring 7, only need compress tightly jump ring 7 to the outside of snap ring 9, based on corner cut 12 and the extrusion to jump ring 7, jump ring 7 can take place compression deformation, reduces its external diameter and finally passes through snap ring 9, behind jump ring 9, because inside wedge groove 8 space is enough, jump ring 7 resets based on elasticity, and its one side supports snap ring 9, and the opposite side supports voussoir 6, for voussoir 6 provides the support.

All install the abaculus 6 and jump ring 7 based on above-mentioned installation step at four mounted position, can realize the installation to the clamp, the mounting means is simple, and the installation back clamp is regular annular structure almost, and the area of outstanding pipeline is little, avoids the collision.

above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
