Description

Technical Field

[0001] This invention belongs to the field of cable protection, specifically a cable tray damage prevention and protection device suitable for the highly corrosive environment of a mineral processing plant. Background Technology

[0002] During the production process in a mineral processing plant, cable trays, serving as carriers of power and control signals, are exposed to harsh environments characterized by high humidity, high dust levels, and the coexistence of acidic and alkaline corrosive media. While commonly used hot-dip galvanized cable trays offer some corrosion resistance, the zinc layer is easily corroded by acids and alkalis and worn away by ore debris under the intense corrosive conditions of a mineral processing plant, leading to accelerated corrosion of the tray substrate and a significantly shortened service life. Stainless steel cable trays offer superior corrosion resistance, but their high cost and extensive installation significantly increase project expenses. Furthermore, vibrations generated by the operation of large equipment within the mineral processing plant are transmitted to the cable trays. Prolonged vibration can cause loosening of the cable trays and cable fasteners, leading to cable displacement, wear, and even the risk of short circuits.

[0003] Traditional cable trays are typically fixed using a single bolt connection, resulting in poor vibration resistance. Furthermore, the sealing structure of the cable trays is inadequate, allowing dust to easily accumulate inside, affecting cable heat dissipation and insulation performance, and increasing the incidence of electrical faults. In addition, current technologies for corrosion protection of cable trays mostly rely on surface plating treatments without designing protective structures tailored to the specific operating conditions. Vibration resistance designs are also often simple reinforcements, failing to address vibration transmission issues from the perspectives of vibration reduction and buffering, thus failing to meet the long-term stable operation requirements of mineral processing plants. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A cable tray damage protection device suitable for highly corrosive environments in mineral processing plants includes:

[0006] Install bracket,

[0007] The main body of the cable tray is independently arranged above the mounting bracket. The outer side of the main body of the cable tray is provided with a wear-resistant and anti-corrosion coating, the inner side of the main body of the cable tray is provided with a buffer protective layer, and the cable limiting component is installed inside the main body of the cable tray.

[0008] The damping assembly includes an upper support base and a lower support base. The upper support base is installed at the bottom of the cable tray body, and the lower support base is installed above the mounting bracket. The upper support base and the lower support base are connected by a damping component.

[0009] Sealing components are installed between the joints of the cable tray body.

[0010] In the cable tray damage prevention and protection device suitable for the highly corrosive environment of a mineral processing plant, the shock-absorbing component includes a damping spring and a rubber damping pad. The damping spring is evenly distributed between the upper support and the lower support, and the rubber damping pad is disposed on the contact surface of the upper support and the lower support.

[0011] In the cable tray damage prevention and protection device applicable to the highly corrosive environment of a mineral processing plant, the shock absorber includes an upper shock absorber seat and a lower shock absorber seat. The upper shock absorber seat is installed on an upper support seat, and the lower shock absorber seat is installed on a lower support seat. Two sets of horizontally symmetrical moving bodies are movably installed on the upper shock absorber seat through multiple sets of elastic damping elements. A fixed body is provided on the lower shock absorber seat, and the two sets of moving bodies are located on both sides of the fixed body.

[0012] The upper and lower shock absorber seats are connected by a sealing cover, which is fitted onto the outside of the elastic damping element, the moving body, and the fixed body.

[0013] When the fixed body has a vertical tendency to move relative to the moving body, the moving body has a horizontal tendency to move relative to the upper shock absorber.

[0014] In the cable tray damage prevention and protection device applicable to the highly corrosive environment of the mineral processing plant, the upper shock absorber includes a fixed frame installed on the upper support base, a fixed ring installed on the inner side of the fixed frame, and guide rings extending outward at both ends of the fixed ring. Guide holes with corresponding positions are provided at the bottom of the guide ring and the fixed frame.

[0015] The lower shock absorber includes two sets of mounting brackets fixed on the lower support base and a guide column fixed in the middle of the lower support base. The middle of the mounting bracket is hollowed out for the fixing frame to pass through. The mounting bracket part is located inside the fixing frame. The two sets of fixing brackets are fixed together by a connecting shaft. The guide column and guide hole are positioned and adapted to each other.

[0016] In the cable tray damage prevention and protection device suitable for the highly corrosive environment of a mineral processing plant, the fixed body is fixedly mounted on the connecting shaft, and the side wall of the fixed body relative to the moving body is an inclined surface.

[0017] The movable body is slidably mounted on the outside of the connecting shaft. The side of the movable body relative to the fixed body is an inclined surface two. Inclined surface one and inclined surface two are set to abut against each other. The side of the movable body facing the fixed ring is provided with a concave ring, and the concave ring and the guide ring are slidably engaged.

[0018] In the cable tray damage prevention and protection device applicable to the highly corrosive environment of a mineral processing plant, the elastic damping component includes a damping rod and a spring. One end of the damping rod is fixed to the upper shock absorber seat, and the other end is fixed to the moving body. A spring is fitted on the damping rod between the upper shock absorber seat and the moving body.

[0019] In the cable tray damage prevention and protection device applicable to the highly corrosive environment of a mineral processing plant, the cable limiting component includes limiting buckles distributed at both ends. The two sets of limiting buckles are connected by an adjustable constraint band, which is used to constrain and fix the cables inside the cable tray body.

[0020] In the cable tray damage prevention and protection device applicable to the highly corrosive environment of a mineral processing plant, the cable limiting component includes limiting buckles distributed at both ends. The two sets of limiting buckles are connected by an adjustable constraint band, which is used to constrain and fix the cables inside the cable tray body.

[0021] In the cable tray damage prevention and protection device applicable to the highly corrosive environment of a mineral processing plant, the adjustable restraint belt includes a restraint strip and a connecting seat fixed to the end of the restraint strip. The connecting seat is provided with a through-body, and the through-body is provided with a restraint body for restraining and fixing the restraint strip and a release body for releasing the restraint body from locking the restraint strip.

[0022] In the cable tray damage prevention and protection device applicable to the highly corrosive environment of a mineral processing plant, the through-hole is provided on the through-body for the restraint strip to pass through, the top of the through-hole is provided with a notch, the restraint body is integrally formed in the notch, the side of the restraint body that contacts the restraint strip is provided with a restraint tooth, and the release body is integrally formed on the free end of the restraint body and located at the end opposite to the restraint tooth.

[0023] In the cable tray damage prevention and protection device suitable for the highly corrosive environment of a mineral processing plant, the sealing assembly includes two sets of mounting frames, which are respectively installed on the outer side of the end of the corresponding cable tray body, and the two sets of mounting frames are connected by a corrugated belt.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. This invention constructs a synergistic defense system by setting a wear-resistant and anti-corrosion coating on the outer side of the cable tray body and a buffer protective layer on the inner side. This system can effectively resist the erosion and wear of high humidity, acid and alkali media and ore debris in ore dressing plants, significantly extending the service life of the cable tray and overcoming the shortcomings of traditional galvanized cable trays in terms of insufficient corrosion protection.

[0026] 2. The shock absorber in the shock absorber assembly of the present invention can not only achieve vertical vibration reduction through springs and rubber pads, but its preferred solution also cleverly transforms vertical vibration into lateral movement of a horizontal moving body through a sloped joint structure, and consumes it with elastic damping components, thereby achieving effective isolation of vibration in multiple directions such as vertical and lateral, solving the problem of poor vibration reduction effect in a single direction, and avoiding loosening and wear of cables due to long-term vibration.

[0027] 3. This invention uses cable limiting components (such as adjustable restraint straps) to flexibly fix the internal cables and prevent them from shifting and rubbing. At the same time, the corrugated design of the sealing component can effectively seal the cable tray joints to prevent dust intrusion, and also has flexible compensation capabilities to adapt to thermal expansion and contraction or slight vibration, ensuring the cleanliness of the inside of the cable tray and the stable operation of the cables.

[0028] 4. Compared with the traditional method of setting up damping structures in the horizontal and vertical directions respectively, the integrated damping design of the present invention can achieve efficient vibration reduction in multiple directions while effectively controlling the overall volume and cost, making it more suitable for practical application scenarios with limited space and cost sensitivity in mineral processing plant workshops.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0044] Example 1

[0045] like Figures 1 to 7 As shown, a cable tray damage prevention and protection device suitable for the highly corrosive environment of a mineral processing plant includes:

[0046] Mounting bracket 20,

[0047] The cable tray body 10 is independently arranged above the mounting bracket 20. The outer side of the cable tray body 10 is provided with a wear-resistant and anti-corrosion coating, the inner side of the cable tray body 10 is provided with a buffer protective layer, and the cable limiting component 40 is installed inside the cable tray body 10.

[0048] The shock absorption assembly 30 includes an upper support 32 and a lower support 31. The upper support 32 is installed at the bottom of the cable tray body 10, and the lower support 31 is installed above the mounting bracket 20. The upper support 32 and the lower support 31 are connected by a shock absorber 33.

[0049] Sealing assembly 50 is installed between the joints of the cable tray body 10.

[0050] In use, the mounting bracket 20 is installed on the designated ground in the factory area, and the cable tray body 10 is fixed by the vibration damping component 30. The cables are installed inside the cable tray body 10 and fixed by the cable limiting component 40 to prevent vibration and friction damage to the cables. A cover plate can be added to the top of the cable tray body 10 to cover and protect the internal cables. The sealing component 50 protects the joints to prevent dust from entering the factory area. During vibration, the vibration damping component 33 of the vibration damping component 30 provides vibration damping. If necessary, a corrugated sleeve (acid and alkali resistant and wear-resistant material) can be added to the outside of the vibration damping component 30 to protect its internal structure.

[0051] The damping component 33 in this embodiment includes a damping spring 331 and a rubber damping pad 332. The damping spring 331 is evenly distributed between the upper support 32 and the lower support 31. The rubber damping pad 332 is disposed on the contact surface between the damping spring 331 and the upper support 32 and the lower support 31, or the upper support 32 and the lower support 31 are directly connected by a damping rod. The damping spring 331 is fitted on the outside of the damping rod, and its two ends are in contact with the upper and lower support seats respectively, so that the spring and the damping rod work together to achieve the damping operation.

[0052] like Figures 3 to 5 As shown, the cable limiting member 40 in this embodiment includes limiting buckles 41 distributed at both ends. The two sets of limiting buckles 41 are connected by an adjustable constraint band 42, which is used to constrain and fix the cable inside the cable tray body 10.

[0053] The adjustable restraint band 42 includes a restraint band strip 421 and a connecting seat 422 fixed to the end of the restraint band strip 421. The connecting seat 422 is provided with a through body 423. The through body 423 is provided with a restraint body 424 for restraining and fixing the restraint band strip 421 and a release body 425 for releasing the restraint body 424 from locking the restraint band strip 421.

[0054] The through-hole 423 is provided with a through-hole for the restraint strip 421 to pass through. A notch is provided at the top of the through-hole. The restraint body 424 is integrally formed in the notch. A restraint tooth is provided on the side of the restraint body 424 that contacts the restraint strip 421. The release body 425 is integrally formed on the free end of the restraint body 424 and is located at the end opposite to the restraint tooth.

[0055] After the cable is installed inside the cable tray body 10, the restraint strip 421 is passed through the through opening. While passing through, the restraint teeth are used to restrain and fix the restraint strip 421. At the same time as the restraint is fixed, the release body 425 abuts against the top surface of the through body 423 while the restraint teeth are subjected to reverse force, ensuring that the restraint teeth will not separate. When it is necessary to loosen, the release body 425 is operated in the opposite direction to separate the restraint teeth, thereby loosening or completely releasing the restraint strip 421.

[0056] The sealing assembly 50 in this embodiment includes two sets of mounting frames 51, which are respectively installed on the outer side of the ends of the corresponding cable tray bodies 10. The two sets of mounting frames 51 are connected by a corrugated strip 52. The two sets of mounting frames 51 are respectively fixed to both ends of the cable tray bodies 10, and the mounting frames 51 of two adjacent cable tray bodies 10 are connected by a corrugated strip 52 (acid and alkali resistant and wear-resistant material) to achieve flexible compensation and protection of their internal structure.

[0057] Example 2

[0058] Unlike Example 1, considering that the vibrations generated by equipment operation in a mineral processing plant typically include both vertical and lateral components, installing a damping structure in only one direction will not provide ideal damping performance; while conventional bidirectional independent damping solutions would significantly increase the size and cost of the equipment, making them unsuitable for the space constraints of the plant site. Therefore, this embodiment provides an integrated multidirectional damping structure, the specific solution of which is as follows:

[0059] like Figures 8 to 13 As shown, the damping component 33 includes an upper damping seat 3302 and a lower damping seat 3301. The upper damping seat 3302 is mounted on an upper support seat 32, and the lower damping seat 3301 is mounted on a lower support seat 31. Two sets of horizontally symmetrically arranged moving bodies 3304 are movably mounted on the upper damping seat 3302 through multiple sets of elastic damping components 3303. A fixed body 3305 is provided on the lower damping seat 3301, and the two sets of moving bodies 3304 are located on both sides of the fixed body 3305 respectively.

[0060] The upper damping seat 3302 and the lower damping seat 3301 are connected by a sealing cover 3306, which is fitted on the outside of the elastic damping element 3303, the moving body 3304 and the fixed body 3305.

[0061] Its damping principle is as follows: when the fixed body 3305 has a vertical movement tendency relative to the moving body 3304, the vertical movement is converted into a horizontal movement tendency of the moving body 3304 relative to the upper damping seat 3302 through the inclined plane cooperation between the two, and then the damping force is provided by the elastic damping element 3303 to achieve damping.

[0062] The upper shock absorber 3302 includes a fixed frame 33021 mounted on the upper support 32. A fixed ring 33022 is installed on the inner side of the fixed frame 33021. Outwardly extending guide rings 33023 are respectively provided at both ends of the fixed ring 33022. Guide holes 33024 with corresponding positions are provided at the bottom of the guide ring 33023 and the fixed frame 33021.

[0063] The lower shock absorber 3301 includes two sets of mounting brackets 33011 fixed on the lower support 31 and a guide post 33013 fixed in the middle of the lower support 31. The middle part of the mounting bracket 33011 is hollowed out for the fixing frame 33021 to pass through. The mounting bracket 33011 is partially located inside the fixing frame 33021. The two sets of fixing brackets 33011 are fixed together by a connecting shaft 33012. The guide post 33013 and the guide hole 33024 are positioned correspondingly and adapted to each other to provide guidance for vertical movement.

[0064] The fixed body 3305 is fixedly mounted on the connecting shaft, and the side wall of the fixed body 3305 relative to the moving body 3304 is an inclined surface.

[0065] The movable body 3304 is slidably mounted on the outside of the connecting shaft. The side of the movable body 3304 relative to the fixed body 3305 is an inclined surface two. The inclined surface one and the inclined surface two are set to abut against each other. The side of the movable body 3304 facing the fixed ring is provided with an inner concave ring. The inner concave ring and the guide ring are slidably engaged and play a guiding role in the horizontal movement of the movable body 3304.

[0066] The elastic damping element 3303 includes a damping rod and a spring. One end of the damping rod is fixed to the upper shock absorber 3302 and the other end is fixed to the moving body 3304. A spring is fitted on the damping rod between the upper shock absorber 3302 and the moving body 3304.

[0067] When subjected to vertical vibration, the lower damping seat 3301 moves downward or upward, causing the fixed body 3305 to move relative to the moving body 3304. Since the fixed body 3305 and the moving body 3304 are in a sloped contact fit, the vertical movement of the fixed body 3305 pushes the moving body 3304 to slide horizontally away from the fixed body 3305 along the connecting shaft 33012, thereby compressing or stretching the elastic damping element 3303, converting the vertical vibration energy into horizontal damping energy dissipation, thus achieving vertical vibration reduction. Similarly, when subjected to lateral vibration, the sloped contact between the moving body 3304 and the fixed body 3305 can also generate an interaction force, which is then attenuated by the elastic damping element 3303. Therefore, this embodiment can achieve bidirectional vibration reduction in both vertical and lateral directions simultaneously through a single integrated structure, effectively improving the vibration reduction effect while avoiding a significant increase in the device size.

[0068] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made to the technical solutions and inventive concepts of the present invention should all be covered within the scope of protection of the present invention.
