Abstract
The utility model belongs to underground optical cable laying tools, and particularly relates to a ditching wiring unit installed on a transverse beam of an assembling soil spade of a pushdozer. For solving the problems of optical cable friction and difficult cable leading of the wiring unit, the ditching wiring unit comprises a spade body (1), a spade blade (2) and a spade point (3) which are used for ditching and a wiring unit (4) fixed on the spade back, and is characterized in that the wiring unit (4) consists of a wire conduit used for threading and a protecting jacket arranged on the inner wall of the wire conduit; the protecting jacket consists of two anti-drop rings (4-1) which can prevent steel balls from dropping off; a ring of steel balls (4-2) are arranged between the two anti-drop rings; the two anti-drop rings are buckled into a whole by two semicircular fixing rings (4-3); and the fixing rings are fixed in the wire conduit (4-4).
Description
Technical field:
Belong to underground optical cable and lay power tool, be specifically related to the trench digging wiring unit on a kind of crossbeam that is installed in bulldozer assembling break shovel.
Background technology:
During the provided underground opto-electrical cable, utilizing bulldozer to ditch and connecting up has been known technology, the patent No. 200620021204.4, name is called " novel optical cable roll off the production line automatically device " and the patent No. 200720093952.8, name is called " wiring unit of laying cable underground ", what provide all is to utilize bulldozer trench digging wiring patent, also all be improvement and the design of carrying out on the basis with the break shovel trench digging of bulldozer configuration, break shovel is by the shovel body, spear, the edge of shovel three parts are formed, and with bearing pin fuse (referring to Fig. 1), patent device and the break shovel difference of rolling off the production line is first, it highly is far longer than break shovel, second to patent shovel body according to the wiring needs, patent shovel body back is provided with cloth (putting) wire casing and lead pulley; Weak point is that opto-electrical cable and unwrapping wire groove inwall have friction, artificial lead-in wire trouble.
Summary of the invention:
The utility model purpose provides a kind of trench digging wiring unit that is installed on the bulldozer.
The technical solution of the utility model is: be installed in the trench digging wiring unit on the bulldozer, comprise shovel body, the edge of shovel, the spear that is used to ditch and be fixed on wiring unit on the back-off, it is characterized in that described wiring unit is made up of the protective jacket that is equipped with on a conduit that is used for threading and the conduit inwall, described protective jacket is can prevent to be equipped with a circle steel ball between its two of the anti-knocking overs that steel ball comes off by two, retainer plate by two semicircles fastens one with it again, and retainer plate is fixed in the conduit.
Described conduit line outlet one end has bent angle.
The utility model has solved opto-electrical cable friction and lead-in wire difficulty.

Fig. 1 is the supporting break shovel schematic diagram of bulldozer;
Fig. 2 is a trench digging wiring unit schematic diagram;
Fig. 3 is a wiring unit longitudinal profile enlarged drawing among Fig. 2;
Fig. 4 is the partial enlarged drawing of A among Fig. 3;
Mark among the figure: 1 shovel body, 2 edge of shovel, 3 spears, 4 wiring units, the anti-knocking over of 4-1,4-2 steel ball, 4-3 retainer plate, 4-4 conduit.
The specific embodiment
In conjunction with the accompanying drawings specific embodiment is further specified:
It specifically is the underground trench digging wiring unit on a kind of crossbeam that is installed in bulldozer assembling break shovel, comprise the shovel body (1) that is used to ditch, the edge of shovel (2), spear (3), its wiring unit (4) is fixed on the back-off of shovel body, it is used to wear the conduit (4-4) of opto-electrical cable by one and is made up of the protective jacket that is arranged on the inside pipe wall, this protective jacket comprises the steel ball (4-2) that prevents the opto-electrical cable friction, prevent the anti-knocking over (4-1) that steel ball comes off and be fixed on retainer plate (4-3) on the conduit inwall, retainer plate is axial two halves to being buckled in steel ball is limited on the anticreep circle and freely rolling in two anti-knocking overs and not coming off, and is not scratched when the steel ball cable down moves.Line inlet port, line outlet, inwall and corner at conduit are provided with protective jacket.The bilateral symmetry of conduit has rectangular skylight, and skylight opening places firm between two rectangle straps on the back-off, and conduit is fixed on the clamping plate.
The present embodiment conduit is a φ 60mm steel pipe, the thick 60mm of shovel body, and long 1950mm, the edge of shovel and spear adopt the abrasion-resistant stee material.
