Description

Technical Field

[0001] The utility model relates to the field of cable protection tube processing, in particular to a hot dip treatment device for a power cable protection tube. Background Art

[0002] A cable protection tube is a metal protection tube with a certain mechanical strength that is laid on the outer layer of the cable surface to prevent the cable from being damaged. The cable protection tube is mainly installed in areas where communication cables and power lines intersect to prevent wire breakage and short circuit accidents, causing communication cables and wire ropes to be electrified, thereby causing damage to the entire power grid. The cable protection tube can protect the cable from short circuits and also play a certain isolation role against magnetic field interference.

[0003] Cable protection tubes are generally made of metal as raw material. Therefore, metal materials will rust and rot if buried deep underground for a long time, and their lifespan is short. Therefore, when we use metal cable protection tubes, we generally need to perform anti-rust and anti-corrosion treatment on the surface of the metal protection tube. Hot dip treatment and coating a layer of protective film on the surface of the metal protection tube can effectively increase the service life of the cable protection tube and reduce the risk of corrosion.

[0004] The existing hot dip equipment for cable protection tubes usually places the cable protection tube into the anti-corrosion material through the equipment, and then takes it up to dry. The existing hot dip equipment for cable protection tubes is widely used, but there are also the following problems: first, the existing hot dip equipment for cable protection tubes directly and arbitrarily clamps the cable protection tube during dipping, resulting in a layer of protective film on the inside of the cable protection tube, which greatly increases the cost and reduces the hot dip efficiency of the cable protection tube. Moreover, after the hot dipped protective tube is separated from the protective liquid, the protective liquid is stained on its surface and it is dried statically, which is slow, resulting in low processing efficiency of the protective tube. Utility Model Content

[0005] The purpose of the utility model is to provide a hot dip treatment device for power cable protection tubes, which solves the problem that the hot dip treatment device for cable protection tubes in the prior art directly and arbitrarily clamps the cable protection tubes during immersion, resulting in a layer of protective film being coated on the inner side of the cable protection tubes, thereby greatly increasing the cost and reducing the hot dip efficiency of the cable protection tubes.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a hot dip treatment device for a power cable protection tube, comprising a base, the upper end of the base is fixedly connected to a support frame, a hot dip box is arranged at one end above the base, a driving motor is fixedly connected to one end of the outer side of the support frame, a lead screw is arranged inwardly through the output end of the driving motor through the support frame, and a threaded block is threadedly connected to the lead screw;

[0007] The lower end of the threaded block is fixedly connected to a cylinder, and the extending end of the cylinder is fixedly connected to a connecting frame, and clamping plates are provided at both ends below the connecting frame, and a sliding rod is fixedly connected to the inside of the support frame, and the threaded block is slidably connected to the sliding rod, and one end of the outer side of the connecting frame is fixedly connected to a driving box, and the driving box passes through the connecting frame and is provided with a bidirectional screw inwardly, and the bidirectional screw is threadedly connected with a threaded block, and a slot is provided at the lower end of the connecting frame, and the threaded block passes through the slot and is fixedly connected to the clamping plate downward, and a sealing block is fixedly connected to the inner side of the clamping plate.

[0008] As a further description of the above technical solution: a collection box is arranged at the other end above the base, and a fixing frame is fixedly connected to the inner end of the support frame.

[0009] As a further description of the above technical solution: the upper end of the base is fixedly connected with an air inlet box, the upper end of the air inlet box is penetrated by an air outlet pipe, the other end of the air outlet pipe penetrates the fixed frame and is internally provided with a connecting pipe, and the connecting pipe is provided with a plurality of air outlet heads.

[0010] As a further description of the above technical solution: a filter box is penetrated through one end of the air inlet box, and a filter screen is arranged inside the filter box.

[0011] The utility model has the following beneficial effects:

[0012] 1. Compared with the prior art, the hot dip treatment equipment for power cable protection tubes can drive the clamping plates at the two ends below to move relative to each other by setting a connecting frame, a driving box, and a bidirectional screw. The two ends of the cable protection tube can be positioned and clamped by the clamping plates to ensure the stability of the cable protection tube during hot dip. At the same time, a sealing block can be set to seal the two ends to prevent the protection liquid from flowing into the inner side of the cable protection tube, thereby improving the practicality and automation of the entire hot dip device;

[0013] 2. Compared with the prior art, this kind of hot dip treatment equipment for power cable protection tubes can enable the air outlet to blow cold air outward by setting an air inlet assembly and a connecting pipe, so as to quickly cool the cable protection tube after hot dip. In this way, the excess protective liquid on the protection tube can be effectively blown off, and at the same time, the cooling and solidification of the protective liquid can be accelerated.
