Technical field
The utility model belongs to underground coal mine and powered field, and in particular to a kind of downhole cable fast hitch mechanism.
Background technology
Mine underground cable easily makes moist and by mechanical damage, and generation electric leakage, short-circuit chance are more, because cable is
The most weak link of one of underground power supply used secure context, then how to handle the cable that is damaged fracture well or because length becomes
Change the fast cable joint for needing to block and ensure that its security turns into a major issue of Safety of Coal Mine Production.Existing well
Lower flame retardant cable is divided into three kinds：Armored cable, plastic cable, Plastic-sheathed Cable.The purposes of three kinds of cables is had nothing in common with each other, cable connection
Mode it is relatively simple, be quite time consuming, and volume is larger, relative complex connecting process again implement to be stranded relatively by underground
It is difficult.
Existing cable connector is more, but there is connection process complexity, without versatility, connection conductive effect
Unstable the problems such as, the coupling arrangement as described in patent 201020520270.2 and 201510371722.2, its first conductive core
Line, the second conductive core line are electrically connected by metal spring with the cored wire of cable respectively, because spring easily fails, may cause two
The docking effect of side cable is poor, influences the use of downhole cable, and it is only used for the cable connection of certain specific standard, does not have
There is versatility.
The content of the invention
The utility model is complicated for the connection process for solving the presence of existing cable coupling arrangement, and efficiency is low, connection is conductive
Effect is unstable, poor universality the problems such as, and then there is provided a kind of downhole cable fast hitch mechanism.
The utility model is adopted the following technical scheme that：
A kind of downhole cable fast hitch mechanism, including connection outer barrel, taper fixture block and top bolt, connection outer barrel include structure
One end is provided with taper unthreaded hole, the other end and is provided with screw thread in identical, matching used outer barrel one and outer barrel two, outer barrel one and outer barrel two
Hole, the bigger diameter end diameter of the bigger diameter end of taper unthreaded hole towards screwed hole and taper unthreaded hole is less than screw thread bore dia, outer barrel one and outer
The screwed hole of cylinder two and the bolt buckle at top bolt two ends are connected；The taper unthreaded hole corresponding matching of the outer barrel one and outer barrel two connects
It is connected to the circular hole that clamp cable is provided with taper fixture block one and taper fixture block two, taper fixture block one and taper fixture block two.
The taper fixture block is identical with the taper of connection outer barrel taper unthreaded hole, and the outside diameter of taper fixture block is more than outside connection
The outside diameter of cylinder taper unthreaded hole.
The opening and closing seam in some directions that parallel to the axis is provided with the taper fixture block, the device is used for pair of different cables
Connect.
The circular hole wall is provided with the anticreep line of thread shape.
The connection outer barrel is the double-deck spacer of poly- record ethene of fire retardant insulating.
The taper fixture block and top bolt are made up of red copper.
The utility model has the advantages that：
1st, the device is to make tapered cable fixture block be clamped in the taper unthreaded hole of connection outer barrel by being screwed into top bolt to realize
The connection of two end cables, operating process is simple, can realize the quick connection of cable；
2nd, it is that red copper is made to push up bolt and taper fixture block, is conducted electricity very well, and cable core is directly installed in taper fixture block
Interior and directly contacted with top bolt end face, cable after connection is powered more stable；
3rd, opening and closing seam is provided with the taper fixture block of the device, fixture block is applied to the connection of different cables, versatility is more
It is good；
4th, taper fixture block inwall is thread shape, can effectively ensure that cable deviates from one during later stage use, influence is conductive
Effect.
Brief description of the drawings
Fig. 1 is the utility model and the structural representation after cable butting；
Fig. 2 is assembling schematic diagram of the present utility model；
In figure：1- cables, 2- outer barrels one, 3- fixture blocks one, 4- tops bolt, 5- fixture blocks two, 6- outer barrels two, 7- tapers unthreaded hole, 8-
Screwed hole, 9- circular holes.
Embodiment
With reference to accompanying drawing, embodiment of the present utility model is described further：
Downhole cable fast hitch mechanism as shown in Figure 2, including connection outer barrel, taper fixture block and top bolt 4, couple outer barrel
Including structure is identical, matching used outer barrel 1 and outer barrel 26, in outer barrel 1 and outer barrel 26 one end be provided with taper unthreaded hole 7,
The other end is provided with screwed hole 8, and the bigger diameter end diameter of bigger diameter end towards screwed hole 8 and the taper unthreaded hole 7 of taper unthreaded hole 7 is less than spiral shell
The screwed hole 8 of the diameter of pit 8, outer barrel 1 and outer barrel 26 and the bolt buckle at the top two ends of bolt 4 are connected；The He of outer barrel 1
The taper unthreaded hole corresponding matching of outer barrel 26 is connected with taper fixture block 1 and taper fixture block 25, taper fixture block 1 and taper fixture block
The circular hole 9 of clamp cable is provided with 25.
The taper fixture block is identical with the taper of connection outer barrel taper unthreaded hole 7, and the outside diameter of taper fixture block is more than connection
The outside diameter of outer barrel taper unthreaded hole.Ensure that the taper fixture block bigger diameter end after installing can be protruded from outside taper unthreaded hole all the time, with top
Bolt is touched, then pushing up can promote taper fixture block to coordinate clamping with coupling outer barrel taper unthreaded hole taper fixture block applying power when bolt is screwed into.
In order that the device can apply to the connection of different size cable, some parallel to the axis is provided with taper fixture block
The opening and closing seam in direction, making the cable core of each diameter specifications can insert in taper fixture block and clamping.
Wherein, taper fixture block and top bolt are made up of red copper, with good electric conductivity, and it is fire retardant insulating to connect outer barrel
The poly- double-deck spacer of record ethene, can effectively ensure that the security performance of coupling arrangement.
The specifically used process of the device is as follows：
The original insulating barrier in cable two ends coupled will be needed to dial to go, cable core is inserted into two devices couples after outer barrel,
From the other end by taper fixture block（Cable fixture block）It is uniformly distributed in the taper unthreaded hole for being put into connection outer barrel and surrounds cable core, will be pushed up
The bolt buckle of bolt and two bolt buckles for coupling outer barrel make two devices couple outer barrels to be coupled by reversely rotating, using pulling
Two connection outer barrels are screwed onto not revolvable degree by hand, and the path due to top bolt along bolt buckle is goed deep into always, so that cone
The cable fixture block of the shape inner core of motion up to clamping coupled cable completely in the taper unthreaded hole of connection outer barrel, due to electricity
It is to be processed into thread shape inside cable fixture block, it is ensured that cable and the frictional force of cable fixture block each other, so that cable connection
Head is more firm in tie cable.
Using the device underground electrician can be made to carry simple tool can will damage or strain the cable of more length needs
Quickly link up, it is larger to efficiently solve existing coupling arrangement volume, and elapsed time during connection cable, connecting process is cumbersome
The problems such as, reach the purpose of safe and efficient use cable.
