Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 7, the invention provides a heat dissipation and lubrication device for a compression mold of a power cable, comprising a box body 1 and a cable 4, wherein the cable 4 is pulled to advance by a tractor arranged in front, the left side of the box body 1 is fixedly provided with the compression mold 2, the left side of the compression mold 2 is fixedly provided with a heat dissipation barrel 3, the top of the heat dissipation barrel 3 is fixedly provided with one end of a heat absorption pipe 5, the top of the box body 1 is fixedly provided with an exhaust fan 6, an exhaust opening of the exhaust fan 6 is fixedly connected with the other end of the heat absorption pipe 5, the front of the box body 1 is fixedly provided with a pump machine 7, the front of the box body 1 is fixedly provided with a pipeline 8, the pipeline 8 is divided into an upper section and a lower section, a port of the upper section is fixedly connected with a port of the lower section through two ends of the pump machine 7, one end of the pipeline 8 penetrates through the top of the box body 1, and the inside of the box body 1 is divided into two sections which are respectively positioned on the front and the back of the inner wall of the box body 1, the equal fixed mounting of 8 ports of inside pipeline of box 1 has shower nozzle 14, the other end of pipeline 8 runs through the positive bottom of box 1, the front inner wall of box 1, the equal fixed mounting of back inner wall has last stopper 12, the front inner wall of box 1, the equal fixed mounting of back inner wall has lower stopper 13 that is located stopper 12 below, it has filter 11 to go up movable joint between stopper 12 and the lower stopper 13, cable 4 runs through box 1, compress tightly mould 2 and heat dissipation bucket 3.

Wherein, dodge gate 10 has been seted up on the right side of box 1, and highly being higher than filter 11 at dodge gate 10 top, the dodge gate 10 that box 1 right side was seted up can conveniently take out the filter 11 of inside activity joint from box 1, and can conveniently clear up the internal environment of box 1, avoid lubricated liquid to deposit on the inner wall of box 1, to making new lubricated liquid pour into the muddy pollution that becomes in the box 1, and the top of dodge gate 10 highly be higher than filter 11 then for not making lubricated liquid flow out through the joint gap of dodge gate 10 with box 1, cause the waste of lubricated liquid, the holistic leakproofness of box 1 has been improved.

Wherein, the department fixed mounting that runs through of box 1 inner wall bottom and pipeline 8 has filter screen 16, the size and the 8 looks adaptations of pipeline of filter screen 16, because the diameter of the space between 11 filter screens of filter is sometimes bigger than the diameter of impurity, the unable complete filtration causes the impurity that has to leak into the inner wall bottom of box 1, install new filter screen 16 once more in the department of running through of

pipeline

8 and 1 inner wall of box this moment, and the diameter in space is less than the diameter of the space between 11 filter screens of filter between the filter screen 16, can once filter, pump machine 7 has been protected, it is purer also to make the lubricated liquid of spraying of new round.

Wherein, the cavity has been seted up to heat dissipation bucket 3's inside, and set up the hole that runs through cavity to inner wall department inside the cavity, its leakproofness can be guaranteed to the inside cavity of seting up of heat dissipation bucket 3, again because heat dissipation bucket 3 with compress tightly 2 fixed connection of mould, so utilize the hole to be connected with the cavity, directly absorb the hot-air that compresses tightly 2 insides from heat absorption pipe 5 through air exhauster 6, greatly reduced compress tightly 2 inside heats of mould, further protection compress tightly mould 2 and cable 4, the problem of the ageing and cable 4's of life reduction of compressing tightly mould 2 that has avoided causing because of the heat.

Wherein, the top rear side fixed mounting of box 1 has inlet 9, and the bottom surface fixed mounting of box 1 has liquid outlet 17, can conveniently pour into lubricated liquid into the box 1 inside through inlet 9, has guaranteed to use brand-new lubricated liquid when new work begins.

Wherein, the contained angle of box 1 top surface inner wall and left and right sides inner wall is the arc, because shower nozzle 14 sprays the state for relatively, so cause spun lubricated liquid to spray each corner of box 1 inner wall, so set up box 1 top surface inner wall and the contained angle of controlling the inner wall into the arc to utilize curved streamline to make lubricated liquid can be quick flow down from the left and right sides inner wall of box 1.

Wherein, 1 inner wall bottom surface of box is the arc, and the minimum point of arc bottom surface and filter screen 16's minimum are kept level, and the bottom surface of 1 inner wall of box sets up to the arc, and the curved bottom surface can effectually make lubricated liquid collect to the depressed part at arc middle part, collects in filter screen 16 department, can make things convenient for the quick lubricated liquid of its bottom of absorption of pump machine 7 to reached the work of incessant lubricated liquid that sprays fast.

Wherein, 1 inner wall left side fixed mounting of box has brush head 15, and brush head 15's diameter is greater than cable 4's diameter, some lubricating liquid that shower nozzle 14 sprayed can spout cable 4 surperficial bold impurity, but some impurity that the adhesive force is strong is difficult to spout by the shower nozzle, so brush head 15 at the left side fixed mounting of box 1 inner wall, through the traction of tractor, cable 4's surface is rubbed through brush of brush head 15, can brush some impurity that the adhesive force is strong to filter 11 on, and brush head 15 also can paint more even with the lubricating liquid on cable 4 surface, make going on that hold-down cable 4's work is more smooth, thereby high-quality lubricated work has been reached.

The working principle and the using process of the invention are as follows:

firstly, lubricating liquid is filled into a box body 1 through a liquid inlet 9, then a cable 4 needing to be compressed is inserted from the tail end of the box body 1, penetrates through a brush head 15 and is inserted into a thick opening of a compression mould 2, a pump 7 is started immediately to sufficiently pump the filled lubricating liquid to each corner in a pipeline 8, then a spray head 14 is started to uniformly spray the lubricating liquid on the surface of the cable 4, one part of the sprayed lubricating liquid is uniformly attached to the surface of the cable 4, the other part of the sprayed lubricating liquid carries impurities on the outer wall of the cable 4 to fall down onto a filter plate 11, the impurities attached to the lubricating liquid are filtered by the filter plate 11 through the filtration of the filter plate 11, the filtered lubricating liquid flows into the bottom of the box body 1 through the filter plate 11 and finally converges in the middle of the bottom through an arc-shaped bottom surface, and the secondary filtration of the filter screen 16 is sucked into a pipeline by the pump 7 to be sprayed for recycling, and cable 4 is continuously forward by the tractor pulling, the lubricated liquid on cable 4 surface is being paintd even back by brush head 15, being pulled out from the thin mouthful department that compresses tightly mould 2 by the tractor, and air exhauster 6 just begins work in step when shower nozzle 14 sprays lubricated liquid, cable 4 is in the twinkling of an eye pulled out from the thin mouthful department that compresses tightly mould 2, the heat that compresses tightly the department just is siphoned away from heat-dissipating bucket 3 by air exhauster 6, compress tightly cable 4 work completion back, get rid of the inside lubricated liquid of box 1 through the liquid outlet 17 of box 1 bottom, taking out inside filter 11 opening dodge gate 10 on box 1 right side, it can to pour the residue.
