Description

Heavy cable docking facilities

Technical field

the present invention is mainly used in heavy cable docking and uses.

Background technology

my unit, in research and production activity, often run into cable and fall short of, or cable breakage can not use, and common way changes a long cable maybe to be changed by the cable of fracture, and the cable changed can not use usually, causes great waste.The cable butt joint device patent of having applied at present, there is docking insufficient strength, cable is easy to the problem from joint pull-out; The cable butt connecting box patent of having applied for then volume is too large, is inconvenient to use.

Summary of the invention

the invention solves the problems referred to above, it is primarily of upper and lower clamp (1), bolt (2), cushion block (3), cable core (4), stopper rod (5), and nut (9) forms, two sections, the left and right of upper and lower clamp (1) has four bolts hole (6) respectively, and there is semicircle concave arc (10) at the middle part of upper and lower clamp (1), and bolt hole (6) has internal thread, the shaft of stopper rod (5) has external screw thread (8), and the left end of stopper rod (5) has stopper rod cap (11), and the right-hand member of stopper rod (5) has conical head (7), the cable core (4) at the two ends, left and right of docking is needed to put into respectively, in the groove of lower clamp (1), cushion block (3) is placed on, between lower cable core (4), bolt (2) is screwed into, in the internal thread of the bolt hole (6) of lower clamp (1), by upper, lower clamp (1) connects into entirety, by on conical head (7) aligning of stopper rod (5), the center, hole that the semicircle concave arc (10) in the middle part of lower clamp (1) is formed, and stopper rod (5) is pushed in hole, the shaft of stopper rod (5) is upper by what force in hole, lower cable core (4) is squeezed into arc, the shaft external screw thread (8) nut (9) being tightened stopper rod (5) by stopper rod (5) with upper, lower clamp (1) connects.Need to illustrate: cushion block (3) is that the electric conducting material with certain ductility manufactures.

Embodiment

below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

see Fig. 5, Fig. 6, two sections, the left and right of clamp (1) has four bolts hole (6) respectively, there is semicircle concave arc (10) at the middle part of clamp (1), and upper clamp (1) and lower clamp (1) full symmetric, can form a hole after upper and lower clamp (1) is assembled in the middle; See Fig. 8, the shaft of stopper rod (5) has external screw thread (8), and the left end of stopper rod (5) has stopper rod cap (11), and the right-hand member of stopper rod (5) has conical head (7); See Fig. 7, cushion block (3) has upper sunken arcs, and the convex arc surface of its concaved circular cambered surface and cable core (4) matches, and cushion block (3) has two, and the length of every block cushion block (3) is consistent with clamp (1) left flat segments or right flat segments; See Fig. 1, Fig. 2, Fig. 3, Fig. 4, two, the left and right first need docked cable core (4) puts into the groove of upper and lower clamp (1) respectively, and make the right-hand member of fracture end alignment upper clamp (1) of left side cable core (4), the left end of fracture end alignment lower clamp (1) on the right cable core (4), vice versa; Two pieces, left and right cushion block (3) is put between upper and lower two cable cores (4), makes the convex globoidal of two upper and lower two cable cores (4) of cancave cambered surface alignment up and down of cushion block (3); Bolt (2) is screwed in the bolt hole (6) of upper and lower clamp (1), and make bolt (2) front end enter the distance of bolt hole (6) two to three pitch of lower clamp (1), upper and lower clamp (1) can be made like this to retain certain gap, and two, left and right cable core (4) keeps linear state at upper and lower clamp (1) simultaneously; By the center, hole that semicircle for the middle part of lower clamp (1) on conical head (7) aligning of stopper rod (5) concave arc (10) is formed, also aim at the gap between upper and lower two cable cores (4) simultaneously, and stopper rod (5) is pushed in hole, upper and lower cable core (4) in hole is squeezed into arc by pressure by the shaft of stopper rod (5), nut (9) is screwed into the shaft external screw thread (8) of stopper rod (5) and tightening nuts (9), stopper rod (5) is connected with upper and lower clamp (1); Finally whole bolts (2) is tightened, complete the docking of unit cable core (4), used the same method the docking of all the other cable cores, finally use conventional method, every root is put into special mould to the cable core connected, inject insulation slurries, complete whole cable butting work.

special explanation advantage of the present invention is as follows:

one. upper and lower cable core (4) is squeezed into semicircle in the hole that the semicircle concave arc (10) in the middle part of upper and lower clamp (1) is formed, greatly strengthen the frictional resistance between upper and lower cable core (4) and upper and lower clamp (1), make the cable core of docking be difficult to be pulled out, ensure that the intensity of docking cable.

two. cushion block (3) is manufactured by the electric conducting material with ductility feature, after upper and lower two cable cores (4) are clamped, cushion block (3) can be close to the arc surface of upper and lower two cable cores (4), and be stretched in upper and lower two cable core (4) gaps and space, the contact area that upper and lower two cable cores (4) are mutual can be strengthened like this, not only increase electric conductivity, in turn increase the frictional resistance between two cable cores (4).
