Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking, in particular to a water-cooled cable clamp for a consumable furnace. Background Art

[0002] The cable that supplies power to the consumable furnace needs to be continuously cooled due to the large amount of electricity. Therefore, existing consumable furnaces all use water-cooled cables. Water-cooled cables refer to cables that are covered with a tube and continuously fed with flowing water to achieve a cooling effect. The existing installation method is to simply fix the hard cable head with the consumable furnace head, and there is no limit fixation between the water-cooled cable connecting the cable head and the furnace head. Since the water-cooled cable is bendable and soft, it will jump due to the electromagnetic force when a large current passes through the water-cooled cable. This jump affects the life of the cable head. After long-term use, there is a risk of breakage between the cable head and the cable body, which poses a great safety hazard. For example, a short-net hydraulic clamp device that can be disconnected, as disclosed in the application number "CN201220605524.X", mainly includes a clamp body, a short net a, a clamp hydraulic cylinder, a water-cooled cable, a short net b, and a furnace head, wherein the clamp hydraulic cylinder is connected to the clamp body, the clamp body is placed on the short net a, and one end of the short net b is vertically connected to the short net a. It mainly uses hydraulic cylinders to control the contact of the cable head, and the water-cooled cable body connected to the cable head will still have a large jump under high current. After long-term use, it is inevitable that the cable will break at the soft and hard junction. Therefore, it is very necessary to design a structure that can effectively prevent the soft and hard junctions of the water-cooled cable from moving and jumping. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation mode of the present invention will be further described in detail below. The present utility model will be further described below in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] A consumable furnace water-cooling cable clamp comprises a base 1, a connecting plate 2 and a jacket 3, wherein the base is arranged on the outer surface of a furnace head 01, a water-cooling cable 4 is detachably arranged in the jacket, the jacket is connected to the base through a connecting plate, a mounting seat 5 for mounting a cable head 6 is correspondingly arranged on the upper inner side of the jacket, the mounting seat is fixed on the outer surface of the furnace head, the cable head is connected to the water-cooling cable portion passing through the upper end of the jacket, and each water-cooling cable connected to the furnace head of the consumable furnace is fixed by the jacket at least at one place.

[0026] By setting the above structure, the water-cooled cable body is fixed by a clamp just below the hard-held cable head, so as to limit and fix the soft and hard junction of the cable, thereby preventing excessive vibration at the junction when a large current passes, ensuring that the connection between the water-cooled cable and the cable head is stable and not easy to break, and ensuring the safe use of the equipment.

[0027] Embodiment 2:

[0028] Each water-cooled cable is fixed by the jacket at least at the top and bottom. That is, there are at least two fixed points from top to bottom directly below the cable head to fix the water-cooled cable, thereby improving the strength of the soft-hard junction at the upper end of the water-cooled cable through multi-point fixation, and at the same time, it is not easy to loosen at the clamp when the furnace head moves with the water-cooled cable. And fixing the jacketed water-cooled cable at at least two points can buffer the jump caused by the large current passing through twice, and more effectively reduce the impact and jump on the soft-hard junction.

[0029] Embodiment three:

The upper and lower fixing points of the water-cooling cable are connected to different connecting plates respectively, so that the connection at the two places is not disturbed and the connection is stable. Even if one place is loose or deflected, the normal and stable use of the water-cooling cable can be guaranteed.

[0031] Embodiment 4:

[0032] The difference from the above embodiment is that the jacket includes an inner jacket 31 arranged near the connecting plate and an outer jacket 32 ​​matched with the inner jacket, and sleeve grooves 33 are provided on the opposite surfaces of the inner and outer jackets, and the water-cooled cable is sleeved in a sleeve hole formed by the sleeve grooves of the inner and outer jackets, and the inner and outer jackets are connected to the connecting plate through connecting components. One or more sleeve holes arranged in sequence are provided on each jacket, and convex racks 331 are evenly distributed in the sleeve grooves. The inner and outer jackets embrace to form a sleeve hole for fixing the water-washing cable. Since the water pipe arranged on the outer jacket of the cable is an elastic water pipe, the diameter of the sleeve hole can be smaller than the outer diameter of the water pipe in the natural state during design, so as to ensure that the clamp can be tightly sleeved on the water-cooled cable. The design of the convex rack 331 can also ensure that the water-cooled cable can be firmly fixed and not easy to slide up and down. The fixing of the inner and outer jackets can be fixed by a plurality of long bolts passing through the outer jacket, the inner jacket and the connecting plate in sequence, that is, the above-mentioned connecting component can be a long bolt.

[0033] In order to ensure the insulation safety of the parts close to the cable head, the jacket is made of wood or thick rubber. It is better to use wood materials with relatively poor deformation ability, such as maple.

[0034] Embodiment five:

[0035] The difference from the above embodiment is that a set of water pipe clamping tools is detachably provided on one side of the base, and the set includes a support rod 7 supported on one side of the base and a clamp ring 8 provided on the support rod, and the water pipe is clamped in the clamp ring.

[0036] The water-cooled cable is supplied with pure water through the water pipe 9 through the water hole of the cable head to flow into the water-cooled cable to take away the heat generated by the current and return to the water tank. In order to ensure the reasonable layout of the above water pipes and to prevent the water pipes and the hard water holes on the cable head from breaking when the water pipes can move with the burner head, a kit can be set on the base to fix the water pipes to ensure that the above connection is not easy to break. There are multiple water-cooled cables connected to the burner head, and there are also multiple water pipes for water supply, and there are also water pipes for cooling other parts of the burner head. To line up on the support rod, multiple water pipes can be fixed.

The clamp ring 8 at least partially sinks into the mounting groove and partially exceeds the mounting groove. The above structure ensures that the clamp ring clamps the water pipe well and is not easy to deflect, thereby ensuring the stable fixation of the water pipe. The design of the mounting groove can also improve the strength of the support rod.

[0039] Embodiment seven:

[0040] The difference from the above embodiment is that the rear side of the clamp ring 8 is provided with a connection limiter 81 sunk into the installation groove, the front side is the ring body of the clamp ring, and at least the upper and lower sides of the connection limiter are limiter abutment areas 82 that can abut against the groove top wall and bottom wall corresponding to the installation groove to prevent the clamp ring 8 from rotating. The above connection limiter structure is provided to ensure that the clamp ring will not rotate and the installation is stable, and at the same time, it can ensure that the clamp ring can completely clamp the water pipe to ensure the fastening of the water pipe.

[0041] By setting the above structure, the water-cooled cable body is fixed by a clamp just below the hard-held cable head, so as to limit and fix the soft and hard junction of the cable, thereby preventing excessive vibration at the junction when a large current passes, ensuring that the connection between the water-cooled cable and the cable head is stable and not easy to break, and ensuring the safe use of the equipment.
