[0021] As Figure 1 With Figure 2 The utility model discloses a NW type water -cooling tank body structure for fire -resistant cable production, including water -cooling tank body 1, support plate 2, wherein support plate 2 vertically sets in the tank bottom of water -cooling tank body 1, and makes support plate 2 and tank wall 11 of water -cooling tank body 1 mutually parallel, the top of support plate 2 is provided with several U -shaped grooves 21 of different depth, the both ends of support plate 2 horizontal direction are bent to form the connecting piece 22 to the tank wall 11 direction, and make two connecting pieces 22 and tank wall 11 meet, and the middle of support plate 2 and tank wall 11 between reserve separation gap 10.

[0022] The NW type water cooling tank structure for the production of fire resistant cable is characterized in that a support plate 2 is vertically arranged on the tank bottom of the water cooling tank 1, and the support plate 2 is parallel to the tank wall 11 of the water cooling tank 1. This not only controls the space occupied by the support plate 2 in the water cooling tank 1, but also helps the support plate 2 to have a very stable and reliable supporting effect. A plurality of U-shaped grooves 21 with different depths are arranged on the top of the support plate 2, which can not only meet the height adjustment requirement, but also help to play a stable limiting role, thereby meeting the normal adjustment requirement very well.

[0023] The two ends of the support plate 2 in the horizontal direction are bent to form connecting plates 22 in the direction of the tank wall 11, and the two connecting plates 22 are connected with the tank wall 11. A separation gap 10 is also reserved between the middle of the support plate 2 and the tank wall 11. This not only further improves the stability and reliability of the installation and positioning of the support plate 2, but also provides a very convenient and reliable installation position for the installation of the end of the tow wheel. This not only brings great convenience to the installation and positioning of the tow wheel, but also greatly improves the stability and reliability of the installation and positioning of the tow wheel, which can solve the user's problem.

[0024] Therefore, the NW type water cooling tank structure for the production of fire resistant cable has very high reliability and applicability.

[0025] As shown in Figure 1 and Figure 3 , the NW type water cooling tank structure for the production of fire resistant cable further comprises a tow wheel 3, which comprises a tow shaft part 31 and two overlapping shafts 32 matched with the U-shaped grooves 21. The two overlapping shafts 32 are arranged on the two end faces of the tow shaft part 31 respectively, and the axial center lines of the two overlapping shafts 32 are coaxial. The tow shaft part 31 is embedded in the U-shaped groove 21. Such a tow wheel 3 is very simple and reliable, which not only facilitates manufacturing, but also helps to play a stable installation and positioning role.

[0026] As shown in Figure 3 , the tow shaft part 31 is a plastic tow shaft covered in the middle of a stainless steel shaft. The two ends of the stainless steel shaft covered by the tow shaft part 31 form the overlapping shafts 32. This not only enables the tow wheel 3 to have high structural strength and durability, but also avoids scratching the cable by the tow shaft part 31, thereby helping to further improve the reliability and applicability of the NW type water cooling tank structure for the production of fire resistant cable.

[0027] As shown in Figure 1 and Figure 3As shown, the two ends of the drag shaft part 31 are provided with limiting shafts 33, and the two limiting shafts 33 are covered on the stainless steel shaft, and the diameter of the limiting shaft 33 is larger than the width of the U-shaped groove 21. The limiting shaft 33 can not only be used to enhance the structural strength of the drag wheel 3, but also can not make the length of the drag shaft part 31 too long, and can be used to cooperate with the support plate 2 to enhance the accuracy and stability of the installation and positioning of the drag wheel 3, thereby further improving the reliability and applicability of the NW type water cooling tank structure for producing fire-resistant cable.

[0028] As shown in Figure 3 , the outer circumferential surface of the drag shaft part 31 is provided with an annular groove 311, and the groove bottom and the groove wall of the annular groove 311 are connected by an arc-shaped surface 312. In this way, the limiting and guiding effect of the drag shaft part 31 on the cable is more stable and reliable, thereby improving the accuracy and stability of the cable conveying.

[0029] As shown in Figure 1 , the width K of the separation gap 10 is 15-20mm. This not only can effectively limit the occupation of the internal space of the water cooling tank 1 by the support plate 2, but also can ensure that the installation and positioning of the drag wheel 3 is very convenient, thereby further improving the applicability of the NW type water cooling tank structure for producing fire-resistant cable.

[0030] In actual manufacturing process, the width K of the separation gap 10 can be 15mm, 16mm, 17mm, 18mm, 19mm or 20mm, which can meet the actual manufacturing and use requirements.

[0031] As shown in Figure 1 and Figure 2 , the depth of each U-shaped groove 21 gradually increases in the horizontal direction. In this way, workers can distinguish and observe conveniently, thereby improving the convenience of use.

[0032] As shown in Figure 1 and Figure 2 , the top surface of the support plate 2 is an inclined surface 23, and the height position of the groove bottom of each U-shaped groove 21 gradually increases along the inclination direction of the inclined surface 23. This not only can control the amount of material used, but also can make the installation and disassembly of the drag wheel 3 more convenient, thereby further improving the applicability of the NW type water cooling tank structure for producing fire-resistant cable.

[0033] The support plate 2 is a stainless steel plate. This can make the support plate 2 have high structural strength and durability, thereby further improving the reliability of the NW type water cooling tank structure for producing fire-resistant cable.

[0034] As shown in Figure 1As shown, in the actual manufacturing process, the upper support plates 2 are arranged side by side in the width direction of the water cooling tank body 1, and the connecting pieces 22 at both ends of the support plates 2 are respectively connected with the corresponding tank walls 11; the drag pulley 3 is arranged between the two support plates 2, so that the two overlapping shafts 32 on the drag pulley 3 are respectively rotatably embedded in the U-shaped supporting grooves 21 on the corresponding support plates 2; in this way, the drag pulley 3 can be conveniently and stably supported by the support plates 2. In order to arrange multiple drag pulleys 3 in the length direction of the water cooling tank body 1, multiple groups of support plates 2 can be arranged side by side in the length direction of the water cooling tank body 1, so as to meet the actual use requirements.

[0035] The above embodiment is a preferred embodiment of the present application, and any similar structure and equivalent changes made shall belong to the protection scope of the present application.
