Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, and in particular to a scalding protection device for fire-cutting machine cables. Background Technology

[0002] The heat treatment workshop of the steel plate plant uses a semi-automatic flame cutting machine to cut and sample steel plates. During the operation, the temperature of the steel plate rises continuously with the accumulation of cutting time, accompanied by the splashing of high-temperature cutting debris. During operation, the operator moves the semi-automatic flame cutting machine to process the steel plate, with its power cord moving across the plate. Because the cutting of mold steel requires heated cutting due to process requirements, the steel plate cutting temperature must not be lower than 150℃, and the steel plate thickness must be 150mm. Prolonged high temperatures damage the insulation layer of the power cord, causing frequent burns and insulation breakdown, affecting cutting quality and efficiency, and posing a safety hazard. Therefore, it is necessary to protect the flame cutting machine cable from burns.

[0003] For example, Chinese Patent Application No. 201410654012.6 discloses an open-type cable protection sleeve, including a protective sleeve body, a first connecting strip, and a second connecting strip. The protective sleeve body has an open-side structure. The first connecting strip is installed on one side of the opening of the protective sleeve body, and the second connecting strip is installed on the other side of the opening of the protective sleeve body. The first connecting strip is provided with a protruding buckle, and the second connecting strip is provided with a groove that matches the protruding buckle. The first connecting strip and the second connecting strip are connected by the matching protruding buckle and groove to cover the opening of the protective sleeve body. In this way, the invention has a simple structure and is easy to use. The protective sleeve body has an open-side structure, and the first and second connecting strips are connected by the matching protruding buckle and groove to cover the opening of the protective sleeve body, replacing ordinary cable protection sleeves. This reduces the workload and improves work efficiency when installing and removing cables.

[0004] The cable protective sleeve provided by the above solution can be fitted onto the outside of the cable, and the use of convex buckles and grooves to cover the opening of the protective sleeve body also facilitates easy installation and removal. However, in the specific application environment of flame cutting machines, the cables are generally quite long, and the operation inevitably involves cable movement, causing the cable to twist, bend, and deform. When moving the flame cutting machine, the cable will also rub against the steel plate surface. All of these situations can cause the cable protective sleeve to separate from the cable, thereby weakening the protective effect; or even causing the cable protective sleeve to wear out or crack rapidly, failing to effectively isolate and protect against high temperatures and flying cutting debris. When local protection is inadequate, processing can cause local damage to the cable, affecting the overall service life of the cable and resulting in high maintenance costs.

[0005] Therefore, it is necessary to invent a heat protection device for fire-cutting machine cables to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a heat protection device for fire-cutting machine cables to address the shortcomings of the prior art. The device uses a flexible protective sleeve and a clamp assembly to wrap around the outside of the cable body and achieve the closure of the cut slit of the flexible protective sleeve, thereby solving the shortcomings mentioned in the background art.

The end of the flexible protective sleeve is provided with a clamp assembly for binding the flexible protective sleeve to the cable body. The clamp assembly includes two sets of axisily distributed combined rings. Each combined ring consists of two arc-shaped clamping plates, and an arc-shaped pressure plate is integrally provided on the outer side of each arc-shaped clamping plate. Horizontal plates are integrally provided at both ends of each arc-shaped pressure plate, and strip-shaped grooves are formed on the horizontal plates. The horizontal plates on the two opposing arc-shaped pressure plates are connected by mutually cooperating bolts and nuts, and the bolts slide within the strip-shaped grooves. A locking ring is sleeved on the outer side of the combined ring formed by the two arc-shaped clamping plates. The locking ring consists of a first arc-shaped limiting rail plate and a second arc-shaped limiting rail plate. The first arc-shaped limiting rail plate and the second arc-shaped limiting rail plate are fastened together, and in the combined state, the first arc-shaped limiting rail plate and the second arc-shaped limiting rail plate are centrally symmetrically distributed.

[0011] Preferably, the inner walls of the first and second arc-shaped limiting rail plates are provided with two rail grooves, and the distance between the two rail grooves matches the two sets of coaxially distributed and mating combination rings.

[0012] Preferably, when the ends of the two arc-shaped pressure plates are joined together to form a combined ring, there is a gap between the two sets of arc-shaped pressure plates.

[0013] Preferably, the flexible protective sleeve includes a wear-resistant layer, a heat insulation layer, a braided layer, and a buffer layer, and the wear-resistant layer, heat insulation layer, braided layer, and buffer layer are connected sequentially from the outside to the inside of the flexible protective sleeve.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0029] like Figure 1-5 As shown, a heat protection device for a fire-cutting machine cable includes a flexible protective sleeve 2 that is movably sleeved on the outside of the cable body 1. The outer wall of the flexible protective sleeve 2 has a slit 3. The slit 3 of the flexible protective sleeve 2 can be opened. The flexible protective sleeve 2 is C-shaped and wraps around a curved surface. In the initial state, the flexible protective sleeve 2 is rolled inward and has a certain elastic force. Through the elastic force, the flexible protective sleeve 2 can fit and wrap around the outer wall of the cable body 1. The flexible protective sleeve 2 is provided with a clamping assembly 4 at its end for binding the flexible protective sleeve 2 to the cable body 1; as a preferred embodiment of the clamping assembly 4 given in this utility model, the structure of the clamping assembly 4 is as follows: The clamp assembly 4 includes two sets of axisymmetrically distributed combined rings. Each combined ring consists of two arc-shaped clamping plates 41, and an arc-shaped pressure plate 42 is integrally provided on the outer side of the arc-shaped clamping plate 41. Horizontal plates 43 are integrally provided at both ends of the arc-shaped pressure plate 42. Strip grooves 44 are provided on the horizontal plates 43. The horizontal plates 43 on the two opposing arc-shaped pressure plates 42 are connected by mutually cooperating bolts 45 and nuts 46. The bolts 45 slide within the strip grooves 44. A locking ring is sleeved on the outer side of the combined ring formed by the two arc-shaped clamping plates 41. The locking ring consists of a first arc-shaped limiting rail plate 47 and a second arc-shaped limiting rail plate 48. The first arc-shaped limiting rail plate 47 and the second arc-shaped limiting rail plate 48 are fastened together. In the combined state, the first arc-shaped limiting rail plate 47 and the second arc-shaped limiting rail plate 48 are centrally symmetrically distributed.

[0030] Specifically, in the above technical solution, the side of the arc-shaped pressure plate 42 closest to the arc-shaped clamping plate 41 is connected by a narrow plate 49, and through slots 410 are provided on the arc-shaped pressure plates 42 located on both sides of the narrow plate 49. The arrangement of the through slots 410 and the narrow plate 49 not only reduces the weight of the structure and reduces production costs, but also makes the arc-shaped pressure plate 42 easier to elastically deform, thereby wrapping and pressing it against the outside of the flexible protective sleeve 2.

[0031] Specifically, in the above technical solution, a protrusion 411 is fixedly connected to the inner wall of the arc-shaped pressure plate 42, and the arc-shaped pressure plate 42 is made of elastic metal material. The protrusion 411 contacts the flexible protective sleeve 2, which plays a role in anti-slip and compression, thereby improving the structural stability of the sleeve assembly 4 combined with the flexible protective sleeve 2 and the cable body 1.

[0032] Specifically, in the above technical solution, the inner region of the arc-shaped pressure plate 42 is set as an incomplete ellipse, the inner region of the combined ring is set as a circle, and the maximum axis of the inner wall of the arc-shaped pressure plate 42 is smaller than the inner diameter of the combined ring, while the outer diameter of the combined ring is larger than the outer diameter of the arc-shaped pressure plate 42. This makes the outer end of the combined ring higher than the outer wall of the arc-shaped pressure plate 42, thereby allowing the locking ring to be fitted onto the combined ring and restrained.

[0033] Specifically, in the above technical solution, the inner walls of the first arc-shaped limiting rail plate 47 and the second arc-shaped limiting rail plate 48 are provided with two rail grooves 412, and the distance between the two rail grooves 412 matches the two sets of coaxially distributed and mating combined rings. After the two sets of coaxially distributed adjacent combined rings are mated, the locking ring formed by the first arc-shaped limiting rail plate 47 and the second arc-shaped limiting rail plate 48 can be fitted onto the combined rings, preventing the two sets of combined rings from separating, and the two combined rings can rotate circumferentially.

[0034] Specifically, in the above technical solution, when the ends of the two arc-shaped clamping plates 41 are joined to form a combined ring, there is a gap between the two sets of arc-shaped pressure plates 42. This provides adjustment space for the two sets of arc-shaped pressure plates 42.

[0035] Specifically, in the above technical solution, the flexible protective sleeve 2 includes a wear-resistant layer, a heat insulation layer, a braided layer, and a buffer layer, which are connected sequentially from the outside to the inside of the flexible protective sleeve 2. In actual use, to reduce costs, discarded oxygen tubing can be used to replace the flexible protective sleeve 2, adding a tubing sheath to the cable to improve its high-temperature resistance. This tubing can then be replaced after prolonged use or when it breaks.

[0036] Specifically, in the above technical solution, the number of flexible protective sleeves 2 is at least one segment, and the number of clamping components 4 is at least two. One clamping component 4 is installed at the end of the flexible protective sleeve 2, or they are installed together between the ends of the two flexible protective sleeves 2.

[0037] To improve the protective effect of the protection device and further encase the cable, this embodiment provides, as follows: Figure 6 The installation structure is shown. Specifically, the flexible protective sleeve 2 located on both sides of the cut 3 has several through holes 5 arranged in a linear array, and the multiple through holes 5 on both sides are staggered, with wires 6 threaded through the multiple through holes 5.

[0038] To improve the protective effect of the protection device and further encase the cable, this embodiment provides, as follows: Figure 7 The installation structure is shown. Specifically, the flexible protective sleeve 2 is wrapped with a restraint strap 7, and the restraint strap 7 is made of cloth.

[0039] The protective device provided by this utility model protects the cable body 1. The flexible protective sleeve 2, which is C-shaped and wraps around a curved surface, can be opened through the slit 3 on its surface and is fitted onto the outside of the cable body 1 from the slit 3. Specifically, multiple flexible protective sleeves 2 can be combined to provide long-distance protection for the cable body 1. For example, multiple flexible protective sleeves 2 can be fitted onto the cable body 1, with the ends of adjacent flexible protective sleeves 2 aligned and spliced. Threads 6 are used to guide the cable routing and pass through multiple through holes 5 sequentially. Alternatively, a binding strap 7 can be used to wrap around the entire exterior of the flexible protective sleeve 2 to close the slits. The connection between the cable body 1 and the flexible protective sleeve 2 is further reinforced by the clamp assembly 4. Specifically, at the end of the flexible protective sleeve 2, taking the splicing position of two flexible protective sleeves 2 as an example, four arc-shaped clamping plates 41 are spliced ​​in pairs to form two combined rings and attached to the combined end of the flexible protective sleeve 2. Then, on its outer side, the first arc-shaped limiting rail plate 47 and the second arc-shaped limiting rail plate 48 are fastened to form a locking ring, realizing the axial locking of the two combined rings. Since the inner side of the arc-shaped pressure plate 42 is set as an ellipse and it is made of elastic metal material, the arc-shaped pressure plate 42 can spring back. The cable body 1 and the flexible protective sleeve 2 are pressed tightly against the outside of the flexible protective sleeve 2. The bolt 45 and nut 46 move in the strip groove 44 to effectively bind the cable body 1 and the flexible protective sleeve 2. After connection, the cable body 1 and the flexible protective sleeve 2 are not easy to slip. When the cable body 1 is subjected to torsional force, the two combined rings can rotate circumferentially. The protective structure is made of multi-segment flexible protective sleeve 2. The flexible protective sleeve 2 is not easy to fall off or tear due to torsional force. The cable body 1 is also not easy to fall off from the cut. It has good wrapping properties and helps to reduce the damage caused by high temperature and flying cutting debris.

[0040] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
