Description
Technical Field
The utility model relates to an electric power assembly type structure field especially relates to a can automatic locking prefabricated cable duct bank of butt joint.
Background
The power cable calandria is mainly used for arranging cables and is of a reinforced concrete structure, and a PVC circular pipe is lined inside the power cable calandria and mainly plays a role in protecting underground cables. When the power cable duct bank is installed, perfect butt joint is difficult to achieve, the butt joint part is difficult to achieve complete fitting, and particularly, after a sealing strip is additionally arranged, the joint part is difficult to fit.
The patent number 201821411988.0 of a prefabricated cable duct disclosed by the Chinese patent office in 2019, 4 and 2 is that a cable pipeline is arranged in the prefabricated cable duct, two ends of the prefabricated cable duct are respectively provided with a socket and a socket, and two sections of the prefabricated cable duct are longitudinally butted with the sockets through the sockets. If the socket and the spigot are not completely connected during butt joint, the cable duct cannot be pulled to translate by the force of the bolt alone, and the sealing performance of the butt joint cannot be guaranteed.
Disclosure of Invention
An object of the utility model is to the defect and not enough of above-mentioned prior art, provide a can automatic locking the prefabricated cable calandria of butt joint for people.
In order to achieve the purpose, the utility model adopts the technical proposal that: the prefabricated cable duct bank capable of automatically locking and butting comprises cable duct bank bodies, wherein the cable duct bank bodies are reinforced concrete members, one end of each cable duct bank body is provided with a U-shaped groove, the other end of each cable duct bank body is provided with a protrusion capable of being inserted into the U-shaped groove, the protrusions of two adjacent cable duct bank bodies are butted with the U-shaped grooves, wedge blocks are embedded at the bottoms of the protrusions, wedge holes are formed in the upper surfaces of the bottom edges of the U-shaped grooves, when the wedge blocks are inserted into the wedge holes, the wedge blocks are in contact with inclined planes of the wedge holes, and the protrusions and the gravity of the cable duct bank bodies can generate component force in the horizontal direction of the U-shaped grooves, so that the butted parts of the cable duct bank bodies are locked.
And a sealing strip is arranged in the U-shaped groove.
The wedge block is provided with two, and the corresponding wedge hole is also provided with two.
Both ends side of cable duct bank body all be provided with the bolt groove, two adjacent cable duct bank bodies back of docking, fastening bolt can imbed the bolt groove, after screwing up fastening nut, two cable duct banks are locked and are fixed by the locking.
The utility model discloses a setting of voussoir and wedge hole, cable duct bank body butt joint department can be at the in-process of installation, and the component that produces through gravity is automatic to compress tightly the sealing strip completely, ensure the leakproofness, have simple structure, construction convenience's advantage.

Fig. 2 is a structural section view before the butt joint of the present invention.
Fig. 3 is a cross-sectional view of the butt joint structure of the present invention.
Detailed Description
As shown in fig. 1, the utility model relates to a can automatic lock prefabricated cable duct bank of butt joint, it includes cable duct bank body 10, and cable duct bank body 10 is the reinforced concrete component, and its one end is equipped with U type recess 11, and the other end is equipped with can insert the arch 12 that closes with U type recess 11, and the arch 12 and the butt joint of U type recess 11 of two adjacent cable duct bank bodies 10. Both ends side of cable duct bank body 10 all be provided with bolt groove 13, two adjacent cable duct bank bodies 10 back of docking, two sections bolt grooves 13 are in same straight line, fastening bolt can imbed bolt groove 13, after screwing up fastening nut, fastening bolt head and fastening nut compress tightly two sections bolt grooves 13, two cable duct banks are locked by the lock.
As shown in fig. 2 and 3, a wedge 20 is embedded in the bottom of the protrusion 12, a wedge hole 21 is formed in the upper surface of the bottom edge of the U-shaped groove 11, when the wedge 20 is inserted into the wedge hole 21, the wedge 20 contacts with the inclined surface of the wedge hole 21, and the gravity of the protrusion 12 and the cable duct bank body 10 generates a component force in the horizontal direction of the U-shaped groove 11, so that the butt joint of the cable duct bank body is locked. The contact of the inclined surfaces gives a horizontal component force to the cable duct bank body 10, so that the butt joint of the cable duct bank body 10 is locked. The U-shaped groove 11 is internally provided with a sealing strip 30. The wedge 20 is provided with two corresponding wedge holes 21.
The utility model discloses a voussoir 20 and wedge hole 21's setting, cable duct bank body 10 butt joint department can be at the in-process of installation, through the automatic locking of the component force that gravity produced to compress tightly sealing strip 30 completely, ensure the leakproofness, have simple structure, construction convenience's advantage.
