TECHNICAL FIELD
[0001] The application belongs to the technical field of cable protection sleeve, and particularly relates to a construction machinery cable anti-abrasion protection sleeve. BACKGROUND
[0002] In a large-scale engineering construction site, especially in a high-technology and complex project such as a nuclear fusion device, construction machinery (construction machinery refers to various mechanical equipment used for tasks such as earthwork excavation, transportation, hoisting, compaction, piling, concrete pouring and material handling in the construction of housing construction, road and bridge, water and electricity, nuclear fusion device, etc., including cranes, transport vehicles, excavators, etc., with the characteristics of large power, high weight, frequent movement, high operation intensity, etc.) frequently operates, and the construction machinery cable needs to be laid on the ground for a long time and repeatedly dragged, bent and laid according to the construction progress. Under such working conditions, the cable not only bears the impact of rolling and crushing from heavy equipment, but also faces multiple threats such as hard ground scratching, sandstone embedding and abrasion, and corrosion by corrosive media (such as coolant, cleaning liquid, etc.). Although the traditional cable has a basic insulation and outer sheath structure, it is easy to cause outer skin damage, internal conductor exposure and even short circuit failure under the above extreme combined working conditions, which seriously affects the construction safety and engineering progress.
[0003] There are some cable protection schemes in the prior art. For example, some technical solutions propose to add a wear-resistant sleeve or a buffer block to the outer layer of the cable (such as CN215342059U and CN217719068U), but the protection structure is mostly a monolithic structure that needs to be integrated during cable manufacturing, which is difficult to adapt to the laid cable; another technical solution improves the bending resistance or reduces the friction by using a spring steel strip or a ball mechanism (such as CN218333191U and CN118866451B), but it does not consider the problem of local stress concentration under heavy load rolling, and lacks effective barrier to the intrusion of corrosive liquid. More importantly, the existing protection structure generally does not have the ability of modular assembly and on-site quick installation, and when the cable needs to be frequently moved or partially damaged, the maintenance cost is high and the operation is inconvenient.
[0004] Therefore, there is an urgent need for a cable protection device suitable for complex construction sites, which can be installed on site, has the functions of anti-rolling, buffer energy absorption, anti-skid fixation and corrosion prevention and sealing, to solve the problem of insufficient protection of the existing technology in the dynamic heavy load and multi-factor coupled abrasion scene. SUMMARY
[0005] To address the aforementioned technical problems, this invention provides a protective sleeve for construction machinery cables against wear. This sleeve mechanism is installed on the outside of the cable body. The side-opening clamp of this mechanism, in conjunction with an inner sleeve and an inner pressure sleeve, clamps the cable body on the outside. An arc-shaped connector supports the inner sleeve, and the arc-shaped pressure sleeve further supports the inner pressure sleeve. This creates an inner sleeve that protects the outside of the cable body. When the cable body is used to power construction machinery at a fusion project construction site, the cable body has a double-layer protective structure consisting of the side-opening clamp and the inner sleeve. When the side-opening clamp is under pressure, the arc-shaped connector and the arc-shaped pressure sleeve, with their gourd-shaped cross-section design, deform under the double layer of stress, effectively buffering the crushing and abrasion damage to the inner sleeve and the cable body from external forces. This invention is applicable to cable protection in harsh construction environments such as fusion projects, enabling it to effectively resist heavy machinery crushing, ground abrasion, and corrosive media erosion without altering the original cable structure. It also supports rapid on-site installation, segmented replacement, and long-term reliable operation.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A protective sleeve for construction machinery cables, capable of deforming with cable bending, includes a sheathing mechanism, a splicing mechanism, and a compression sealing mechanism. The sheathing mechanism includes a side-opening clamp tube, with a U-shaped sleeve covering the side opening edge of the side-opening clamp tube. An inner connecting sleeve and an inner compression sleeve are positioned opposite each other inside the side-opening clamp tube. Several arc-shaped spiral splice strips are fixed between the inner connecting sleeve and the side-opening clamp tube, and several arc-shaped compression strips are fixed between the inner compression sleeve and the side-opening clamp tube. Both the arc-shaped spiral splice strips and the arc-shaped compression strips have an arc-shaped body and a gourd-shaped cross-section. The opposing surfaces of the arc-shaped spiral splice strips and the arc-shaped compression strips are connected by a splice assembly. The inner sleeve has a sealing mechanism consisting of a first connecting strip, a second connecting strip, and a third connecting strip, fixed sequentially from the inside out at both ends of the inner sleeve. The inner pressure sleeve also has a sealing mechanism consisting of a first pressure strip, a second pressure strip, and a third pressure strip, fixed sequentially from the inside out at both ends of the inner sleeve. The first connecting strip and the first pressure strip are mated together; the second connecting strip and the second pressure strip are fitted with a clearance fit within the inner sleeve; and the third connecting strip and the third pressure strip are fitted with a clearance fit within the inner pressure sleeve. After the first connecting strip is fixed within the inner sleeve, the second and third connecting strips are fixed one by one, forming a three-section sealing structure in conjunction with the sealing mechanism.
[0008] Beneficial effects:
[0009] 1. In view of the problem that existing protective structures are mostly integral, need to be integrated during the cable manufacturing stage, and are difficult to adapt to the already laid cables, the present invention adopts a side-opening detachable structure with side-opening clamp and U-shaped sleeve, which can directly open and wrap the already laid cables without modifying the original cable structure, thus realizing rapid on-site installation and disassembly.
[0010] 2. In view of the problem that the existing technology does not consider the local stress concentration and lack of effective buffering under heavy load, the present invention adopts a double-layer support structure of arc-shaped joint strip and arc-shaped pressure strip with gourd-shaped cross section design. Under pressure, the stress is effectively dispersed through elastic deformation, so as to avoid the cable being flattened or the sheath being broken.
[0011] 3. In view of the problem that existing technologies lack effective barriers to the intrusion of corrosive liquids, the present invention forms a three-stage sealing structure with the first connecting strip and the first pressure strip connected together, the second connecting strip and the second pressure strip with a gap fit, and the third connecting strip and the third pressure strip with a gap fit, thereby effectively preventing the intrusion of corrosive media such as mud, water, and chemical liquids.
[0012] 4. In view of the problems of existing technologies lacking modular splicing capabilities and high maintenance costs, this invention adopts a multi-segment end-to-end splicing structure. When a part is damaged, only the damaged segment needs to be replaced, without replacing the whole system, which greatly reduces maintenance costs and downtime.
[0013] 5. In view of the problem that the existing technology does not consider the wear caused by the relative sliding of the cable inside the sleeve, the present invention tightly covers the surface of the cable by forming an inner sleeve composed of an inner connecting sleeve and an inner pressure sleeve, and forms a cable-holding structure with a three-section connecting strip and a pressure strip, thereby suppressing the relative sliding of the cable inside the sleeve and reducing friction and wear.
[0014] 6. In view of the problem that the existing protective structure is too rigid and easily leads to cable fatigue damage, the present invention adopts a side-opening clamp tube, inner sleeve and inner pressure sleeve with elastic hard shell structure, combined with the arc-shaped connecting strip and arc-shaped pressure strip with elastic strip design, so that the sleeve has the ability to deform with the bending of the cable and adapt to the needs of frequent dragging and deployment.
[0015] In summary, this invention is particularly suitable for high-risk, high-intensity, and variable construction sites such as fusion engineering projects. Without relying on modifications to the cable itself, it achieves an organic unity of mechanical protection, chemical protection, and engineering practicality, significantly improving the reliability and construction safety of the cable system.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.
[0028] The construction machinery cable wear-resistant protective sleeve of this invention is based on a layered protection and precise adaptation design logic. It achieves synergistic effect through a four-level protection structure of outer impact resistance, middle buffer, inner bonding, and end fixing. It specifically solves the problems of crushing, scratching, pulling wear and displacement faced by cables at fusion project construction sites. At the same time, it takes into account flexibility and sealing performance, and achieves all-scenario protection for cables. Without changing the original cable structure, it effectively resists heavy machinery crushing, ground scratching and corrosive media erosion, and supports rapid on-site installation, segmented replacement and long-term reliable operation.
[0029] like Figures 1-4As shown, the anti-wear protective sleeve for construction machinery cables of the present invention includes a sheathing mechanism 1. The sheathing mechanism 1 includes a side-opening clamp tube 101. The side-opening clamp tube 101 adopts a side-opening design, and a U-shaped clamp 102 is clamped on the side opening edge of the side-opening clamp tube 101. An inner connecting sleeve 104 and an inner pressure sleeve 105 are arranged opposite to each other inside the side-opening clamp tube 101 to form an inner sleeve. A plurality of arc-shaped connecting strips 103 are fixed between the inner connecting sleeve 104 and the side-opening clamp tube 101. A plurality of arc-shaped pressure strips 106 are fixed between the inner pressure sleeve 105 and the side-opening clamp tube 101. The strips of the arc-shaped connecting strips 103 and the arc-shaped pressure strips 106 are both designed in an arc shape, and the cross-section of the strips of the arc-shaped connecting strips 103 and the arc-shaped pressure strips 106 is gourd-shaped. The opposite surfaces of the arc-shaped connecting strips 103 and the arc-shaped pressure strips 106 are connected by a connecting strip assembly.
[0030] The inner sleeve 104 has a sealing mechanism 2 installed in the two ends of the sleeve opening, and the inner pressure sleeve 105 has a pressure sealing mechanism 3 installed in the two ends of the sleeve opening.
[0031] like Figure 7 , Figure 8 , Figure 10 As shown, the sealing mechanism 2 includes a first connecting strip 201, a second connecting strip 202, and a third connecting strip 203, and the pressing mechanism 3 includes a first pressing strip 301, a second pressing strip 302, and a third pressing strip 303. The first connecting strip 201 and the first pressing strip 301 are designed to be butted together. The second connecting strip 202 and the second pressing strip 302 are fitted with a clearance within the inner connecting sleeve 104. The third connecting strip 203 and the third pressing strip 303 are fitted with a clearance within the inner pressing sleeve 105.
[0032] This invention provides a sheathing mechanism 1 on the outside of the cable body 5. When the side-opening clamping tube 101 of the sheathing mechanism 1 is opened, the inner sleeve 104 and the inner pressure sleeve 105 clamp the cable body 5. When the side-opening clamping tube 101 is closed, a U-shaped clamping sleeve 102 prevents loosening. Inside the side-opening clamping tube 101, an arc-shaped connecting strip 103 supports the inner sleeve 104, and an arc-shaped pressure strip 106 supports the inner pressure sleeve 105. This allows the inner sleeve 104 and the inner pressure sleeve 105 to connect and form an inner sheath protecting the outside of the cable body 5. When the cable body 5 is in fusion phase... When used for powering construction machinery at the construction site, the cable body 5 has a double-layer protective structure consisting of a side-opening clamp 101 and an inner sleeve. This provides wear protection on the outside of the cable body 5. When the side-opening clamp 101 is under pressure, the gourd-shaped cross-section arc-shaped connecting strip 103 and arc-shaped pressure strip 106 deform under double-layer stress, effectively buffering the crushing and abrasion damage to the inner sleeve and the cable body 5 caused by external forces. This achieves wear protection for the cable body 5 and solves the problem of easy pressure and wear on the cable body 5 at the fusion project construction site.
[0033] This invention provides a sealing mechanism 2 and a pressure sealing mechanism 3 within the inner sleeve 104 and inner pressure sleeve 105, respectively. When the inner sleeve 104 and inner pressure sleeve 105 are joined to form an inner sleeve protecting the outside of the cable body 5, the first connecting strip 201 of the sealing mechanism 2 and the first pressure strip 301 of the pressure sealing mechanism 3 are joined to form a preliminary sealing structure. Simultaneously, the second connecting strip 202 and the second pressure strip 302 are gap-fitted within the inner sleeve 104 to form a two-stage sealing structure, and the third connecting strip 203 and the third pressure strip 303 are gap-fitted within the arc-shaped pressure strip 106 to form a three-stage sealing structure. As the cable body 5 is tightened with the inner sleeve, these three sealing structures are deformed under pressure and adhere to the cable body 5, forming a three-stage liquid-proof structure. This prevents corrosive media from the fusion project construction site from seeping into the inner sleeve and eroding the outer sheath of the cable body 5, and prevents the cable body 5 from corroding and loosening, causing wear with the inner sleeve, thus achieving safe protection for the cable body 5.
[0034] The present invention provides a sealing mechanism 2 and a pressing mechanism 3 in the inner sleeve 104 and the inner pressure sleeve 105 respectively. The first connecting strip 201, the second connecting strip 202 and the third connecting strip 203 of the sealing mechanism 2 cooperate with the first pressing strip 301, the second pressing strip 302 and the third pressing strip 303 of the pressing mechanism 3 to form a cable-holding structure. When the cable body 5 enters the inner sleeve for clamping, it can help the inner sleeve to hold the cable body 5 tightly and prevent it from loosening, effectively preventing the cable body 5 from loosening and causing wear in the inner sleeve.
[0035] like Figure 3 , Figure 8 and Figure 10 As shown, in this invention, the splice assembly includes a plurality of connecting holes 1032 disposed on the end face of the arc-shaped splice 103 and a plurality of pressure posts 1062 disposed on the end face of the arc-shaped pressure strip 106, with the pressure posts 1062 inserted into the connecting holes 1032. By providing connecting holes 1032 on the end face of the arc-shaped splice 103 and pressure posts 1062 on the end face of the arc-shaped pressure strip 106, this invention ensures that the arc-shaped splice 103 and the arc-shaped pressure strip 106 are not easily separated when subjected to pressure, and that the arc-shaped splice 103 and the arc-shaped pressure strip 106 can be stably protected outside the inner sleeve.
[0036] like Figure 8 As shown, in this invention, a first arc rib portion 1031 is fixed to the inner arc surface of the arc-shaped connecting strip 103, and the first arc rib portion 1031 is fixed to the outer wall of the inner sleeve 104. This invention, by fixing the arc-shaped connecting strip 103 to the inner sleeve 104 with the first arc rib portion 1031, provides a deformable buffer position between the arc-shaped connecting strip 103 and the inner sleeve 104. Utilizing the elastic deformation of the arc-shaped structure, the impact force generated by external vibration is absorbed, improving the fatigue resistance of the connection part.
[0037] likeFigure 10 As shown, in this design, a second arc rib portion 1061 is fixed to the inner arc surface of the arc-shaped pressure strip 106, and the second arc rib portion 1061 is fixed to the outer wall of the inner pressure sleeve 105. This invention, by fixing the arc-shaped pressure strip 106 to the inner pressure sleeve 105 with the second arc rib portion 1061, provides a deformable buffer position between the inner pressure sleeve 105 and the arc-shaped pressure strip 106. Utilizing the elastic deformation of the arc-shaped structure, the impact force generated by external vibration is absorbed, improving the fatigue resistance of the connection part.
[0038] like Figure 5 , Figure 6 , Figure 8 and Figure 10 As shown, in this invention, both the arc-spinning strip 103 and the arc-spinning pressing strip 106 have extrusion blocks 108 fixed to their edges. A strip-shaped groove 107 is provided on the inner wall of the side-opening clamping tube 101 away from the side-opening edge. The extrusion blocks 108 are elastically extruded into the strip-shaped groove 107. This invention provides an easily deformable opening position by providing a strip-shaped groove 107 at the side-opening clamping tube 101, facilitating the opening of the side-opening clamping tube 101 in opposite directions. Then, the arc-spinning strip 103 and the arc-spinning pressing strip 106, along with the extrusion blocks 108, can be extruded into the strip-shaped groove 107 to fill and support the side-opening clamping tube 101 when it is closed, ensuring that the side-opening clamping tube 101 does not deform excessively or become damaged at the strip-shaped groove 107 after closure.
[0039] like Figure 7 and Figure 8 As shown, in this invention, the first connecting strip 201 is fixed inside the two end openings of the inner sleeve 104, and a second connecting strip 202 is fixed to the inner sleeve 104 near the inner wall of the first connecting strip 201, and a third connecting strip 203 is fixed to the inner sleeve 104 near the inner wall of the second connecting strip 202. By fixing the first connecting strip 201 inside the two end openings of the inner sleeve 104, and then fixing the second connecting strip 202 and the third connecting strip 203 one by one, this invention facilitates the formation of a three-section sealing structure in conjunction with the sealing mechanism 3.
[0040] like Figure 7 and Figure 10 As shown, in this invention, the first pressure strip 301 is fixed inside the openings at both ends of the inner pressure sleeve 105, and a second pressure strip 302 is fixed to the inner wall of the inner pressure sleeve 105 near the first pressure strip 301, and a third pressure strip 303 is fixed to the inner wall of the inner pressure sleeve 105 near the second pressure strip 302. By fixing the first pressure strip 301 inside the openings at both ends of the inner pressure sleeve 105, and then fixing the second pressure strip 302 and the third pressure strip 303 one by one, this invention facilitates the formation of a three-section sealing structure in conjunction with the sealing mechanism 2.
[0041] like Figures 1 to 3As shown, in this invention, a mounting hole is provided between the side opening edge of the side-opening clamp tube 101 and the U-shaped sleeve 102, and a bolt passes through the mounting hole of the side-opening clamp tube 101 and the U-shaped sleeve 102 to be threadedly connected to a nut. This invention, by providing a mounting hole between the side-opening clamp tube 101 and the U-shaped sleeve 102, facilitates the bolt passing through the mounting hole of the side-opening clamp tube 101 and the U-shaped sleeve 102 to lock with the nut, thereby locking the U-shaped sleeve 102 and the side-opening clamp tube 101 and preventing the side-opening clamp tube 101 from loosening and opening.
[0042] like Figure 1 and Figure 9 As shown, in this invention, the outer tube wall of the side-opening clamp tube 101 is provided with a plurality of padding mechanisms 4. The padding mechanism 4 includes an inner rolled core strip 401, which is fixed to the outer tube wall of the side-opening clamp tube 101. A plurality of C-shaped pads 402 for wrapping the inner rolled core strip 401 layer by layer are fixed to the outer tube wall of the side-opening clamp tube 101. A gap is provided between adjacent pads of the C-shaped pads 402. This invention provides a padding mechanism 4 on the outer wall of the side-opening clamp tube 101. The padding mechanism 4, with the inner core strip 401 and C-shaped pad 402 forming a multi-layer deformable structure, provides elevated support, making it difficult for the side-opening clamp tube 101 to directly contact the ground. When the side-opening clamp tube 101 is moved by the cable body 5, the padding mechanism 4 provides multi-layer buffering to prevent the side-opening clamp tube 101 from being damaged prematurely by ground friction. At the same time, the two ends of the inner sleeve after being raised are far away from the ground, so that corrosive liquids leaked from the fusion project construction site are less likely to affect the cable body 5 at the inner sleeve, thus providing elevated safety protection for the cable body 5.
[0043] It should be noted that the side-opening clamp tube 101, the inner sleeve 104, and the inner pressure sleeve 105 all adopt an elastic hard shell structure design, and the side-opening clamp tube 101 has the elastic recovery capability of side-opening clamping. The arc-rotating joint strip 103 and the arc-rotating pressure strip 106 adopt an elastic strip design and have the elastic deformation capability. The pressure column 1062, the inner rolled core strip 401, and the C-shaped pad 402 are made of elastic material and have the elastic deformation capability and buffer capability.
[0044] The working process of the anti-wear protective sleeve for construction machinery cables of the present invention is as follows: In use, first open the side opening edge of the side-opening clamp tube 101, then place the inner sleeve, composed of the inner connecting sleeve 104 and the inner pressure sleeve 105, onto the outside of the cable body 5. Next, close the side-opening clamp tube 101 to wrap around the inner sleeve. Use the U-shaped clamp 102 to clamp the side opening edge of the side-opening clamp tube 101, and lock the side-opening clamp tube 101 and the U-shaped clamp 102 together with a bolt and nut threaded connection to prevent the side-opening clamp tube 101 from loosening and opening. At this time, the arc-shaped connecting strip 103 between the side-opening clamp tube 101 and the inner sleeve is fixed to the outer wall of the inner connecting sleeve 104 through the first arc-shaped rib section 1031. The spinning strip 106 is fixed to the outer wall of the inner pressure sleeve 105 via the second arc rib strip 1061, and the connecting hole 1032 on the end face of the arc spinning strip 103 is connected to the pressure post 1062 on the end face of the arc spinning strip 106. At the same time, the extrusion blocks 108 on the edges of the arc spinning strip 103 and the arc spinning strip 106 are elastically extruded into the strip groove 107 of the inner wall of the side-opening clamp tube 101, forming a stable support structure. The padding mechanism 4 of the outer wall of the side-opening clamp tube 101 uses the inner core strip 401 as the skeleton and cooperates with the C-shaped layer pads 402 that are wrapped layer by layer to form a multi-layer buffer structure, raising the side-opening clamp tube 101 so that it does not directly contact the hard ground. When the cable body 5 is carried by the construction machinery in the process of... When the cable is moved or deployed at the construction site, if it encounters heavy equipment or scrapes against hard ground, the outer side-opening clamp 101 will bear the external force first. The gourd-shaped arc-shaped connecting strip 103 and arc-shaped pressure strip 106 will undergo elastic deformation, using their own elasticity to buffer the external force and disperse the pressure transmitted to the inner sleeve, preventing the inner sleeve and cable body 5 from being directly crushed and damaged. At the same time, the C-shaped pad 402 of the padding mechanism 4 will deform due to pressure, and the gap between adjacent pads will be compressed, further absorbing the impact force and reducing the drag friction loss between the side-opening clamp 101 and the ground. In terms of inner sealing protection, the first connecting strip 201 and the second connecting strip 202 inside the inner sleeve 104 02. The third connector 203 corresponds to and cooperates with the first pressure strip 301, the second pressure strip 302, and the third pressure strip 303 in the inner pressure sleeve 105. The first connector 201 and the first pressure strip 301 form a preliminary seal. The second connector 202 and the second pressure strip 302 are fitted together in the inner pressure sleeve 104 to form a second-stage seal. The third connector 203 and the third pressure strip 303 are fitted together in the inner pressure sleeve 105 to form a third-stage seal. As the cable body 5 is tightened with the inner sleeve, these three-stage sealing structures will be deformed under pressure and fit against the outer wall of the cable body 5, forming a tight three-stage liquid-proof structure, which effectively prevents corrosive media from the construction site from seeping into the inner sleeve.Meanwhile, the combined structure of these three-stage splice strips and pressure strips also forms a cable-holding structure, assisting the inner sleeve in tightly gripping the cable body 5, preventing the cable body 5 from loosening or shifting due to equipment vibration and pulling within the inner sleeve, and avoiding frictional wear between the cable sheath and the inner wall of the inner sleeve. The elastic hard shell design of the side-opening clamp 101, inner sleeve 104, and inner pressure sleeve 105, along with the elastic material characteristics of the arc-rotary splice strip 103, arc-rotary pressure strip 106, pressure column 1062, inner rolled core strip 401, and C-shaped pad 402, allows the entire sheathing mechanism 1 to deform with the cable bending, adapting to the pulling and laying requirements of construction machinery cables. Ultimately, this achieves comprehensive protection against crushing, scratching, corrosion, and loosening / wearing of the construction machinery cables at the fusion project construction site, ensuring the safe and stable operation of the cables.
