Description

Technical Field

[0001] This utility model belongs to the technical field of bar screen equipment, specifically a bar screen wire rope anti-wear device that is easy to install. Background Technology

[0002] A bar screen is a solid-liquid separation device that continuously removes impurities from fluids. The bar screen's transmission device consists of sprockets, a frame, and rakes. The rakes are arranged in a specific order through a combination of the rake shaft and the sprockets to form a closed chain of rakes. The transmission device drives the sprockets on both sides to rotate clockwise from bottom to top on the water-facing side. Due to the special structure and shape of the rakes, when the rakes carry impurities to the top of the bar screen, they reverse direction and the impurities fall off by their own weight, thus completing a cycle of cleaning. It is now widely used in river cleaning and water pollution treatment.

[0003] Meanwhile, application number CN212769927U, "Wire Rope Traction Type Bar Screening Machine," describes a wire rope traction type bar screening machine comprising a frame. The top of the frame has a second cover box, and the top of the second cover box overlaps with a first cover box. A rake bucket is slidably connected to the front end of the frame, and wire ropes are installed on both sides of the top front end of the rake bucket. A through hole is opened at the bottom of the rake bucket, and a movable plate is movably connected to the rake bucket within the through hole. This device can completely isolate water flow, forcing water to pass through it before continuing to flow. This solves the problem of pollutant leakage caused by the reserved space at the bottom of traditional bar screens. Furthermore, since this device has only one rake bucket, to prevent pollutants from being trapped at the bottom during the rake bucket's descent and remaining unremoved, this device incorporates a similar one-way valve structure at the bottom of the rake bucket, referencing the one-way valve structure in a manual water pump used in well control.

[0004] During long-term operation, the wire rope frequently rubs against the relevant parts of the bar screen, resulting in severe wear of the wire rope. This not only shortens the service life of the wire rope and increases maintenance costs, but may also cause safety accidents due to wire rope breakage, affecting the normal operation of the bar screen. Furthermore, the wire rope anti-wear device has problems such as inconvenient installation and poor anti-wear effect, making it difficult to meet actual use requirements.

[0005] Therefore, there is an urgent need to design a device that is easy to install and can effectively reduce the wear of wire ropes. Utility Model Content

[0006] To address the problems of inconvenient installation and poor wear resistance of existing anti-wear devices for steel wire ropes in bar screen machines, this paper aims to improve the service life of steel wire ropes, reduce maintenance costs, and ensure the safe and stable operation of bar screen machines.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-install anti-wear device for steel wire rope of a bar screen machine, comprising an anti-wear body and connecting plates B installed at both ends of the anti-wear body. A connecting plate A is provided on one side surface of the connecting plate B, and a mounting seat is installed on the side surface of the connecting plate A away from the connecting plate B. The surface of the mounting seat has mounting holes, and fixing bolts are inserted into the mounting holes of the mounting seat, thereby installing the anti-wear body on the bar screen machine body. The anti-wear body has a U-shaped structure, and a wear-resistant layer is provided on the inner side wall of the anti-wear body. The wear-resistant layer is made of high-molecular wear-resistant material. An installation assembly is provided between the connecting plates A and B.

[0008] Preferably, the mounting assembly includes inserts symmetrically mounted on the surface of the docking plate B near the docking plate A. The mounting base has a docking groove corresponding to the insert, which communicates with a slot on the surface of the docking plate A. The insert is inserted into the docking groove on the surface of the mounting base. A groove is formed on the surface of the insert, and a locking block is slidably disposed inside the groove. One end of the locking block extends to the outside of the insert, and a spring is provided at the end of the locking block. The two ends of the spring abut against the inside of the locking block and the insert, respectively. Two limiting blocks are symmetrically mounted on the surface of the locking block. A limiting groove adapted to the limiting blocks is formed on the inner wall of the groove, and the limiting blocks are engaged in the limiting groove. A downwardly extending locking groove is formed on the surface of the mounting base, the width of which is adapted to the width of the locking block.

[0009] Preferably, the mounting assembly further includes an abutting block adapted to the slot, which abuts against the slot during disassembly.

[0010] Preferably, the card block extends to one end of the outer side of the insertion block and is configured in a triangular block shape.

[0011] Preferably, the surface of the wear-resistant body is provided with a plurality of arc-shaped grooves, the arc-shaped grooves are distributed along the running direction of the wire rope, and the arc-shaped grooves are filled with grease.

[0012] Preferably, the outer side wall of the wear-resistant body is provided with reinforcing ribs, which can enhance the structural strength of the wear-resistant body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention enables rapid installation and disassembly of the wear-resistant body and the bar screen mounting base through the installation components. Compared with traditional installation methods, this greatly improves installation efficiency, reduces installation difficulty, and facilitates later maintenance and replacement. The wear-resistant layer on the inner wall of the wear-resistant body and the grease in the arc groove on the surface effectively reduce the wear of the wire rope from both material and lubrication perspectives, significantly extending the service life of the wire rope and reducing maintenance costs. The U-shaped structure design of the wear-resistant body and the reinforcing ribs on the outer wall ensure comprehensive protection of the wire rope and the stability of its own structure, improving the safety and reliability of the bar screen operation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4As shown, this utility model provides an easy-to-install anti-wear device for steel wire rope of a grating machine, including an anti-wear body 12 and docking plates B13 installed at both ends of the anti-wear body 12. A docking plate A11 is provided on one side surface of the docking plate B13, and a mounting base 1 is installed on the side surface of the docking plate A11 away from the docking plate B13. The surface of the mounting base 1 has mounting holes, and fixing bolts are inserted into the mounting holes of the mounting base 1, thereby installing the anti-wear body 12 onto the grating machine body. The anti-wear body 12 has a U-shaped structure and provides anti-wear protection. A wear-resistant layer is provided on the inner wall of the main body 12. The wear-resistant layer is made of high-polymer wear-resistant material. The wear-resistant main body 12 has a U-shaped structure, which can better wrap the wire rope and provide comprehensive protection. The wear-resistant layer uses high-polymer wear-resistant material, which has excellent wear resistance and corrosion resistance, and can effectively reduce the friction between the wire rope and the wear-resistant main body 12, extending the service life of the wire rope. An installation component 2 is provided between the docking plate A11 and the docking plate B13. The installation component 2 includes components symmetrically installed on the docking plate B13 near the docking plate A11. The mounting base 1 has a corresponding mating groove 22 on one side surface of the insert 21. The mating groove 22 is connected to the slot on the surface of the mating plate A11. The insert 21 is inserted into the mating groove 22 on the surface of the mounting base 1. The surface of the insert 21 has a groove 23. A locking block 24 is slidably disposed inside the groove 23. One end of the locking block 24 extends to the outside of the insert 21. A spring 25 is disposed at the end of the locking block 24. The two ends of the spring 25 abut against the inside of the locking block 24 and the insert 21, respectively. The surface of the locking block 24 is aligned with the inside of the insert 21. The device is equipped with two limiting blocks 26. The inner wall of the groove 23 is provided with a limiting groove 27 that matches the limiting block 26. The limiting block 26 is engaged in the limiting groove 27. The surface of the mounting base 1 is provided with a downward extending slot 28. The width of the slot 28 matches the width of the locking block 24. With this design of the mounting component 2, during installation, the insert block 21 is inserted into the mating groove 22. The locking block 24 pops out under the action of the spring 25 and engages in the slot 28, realizing the quick installation and fixation of the wear-resistant body 12 and the mounting base 1. The installation process is simple and convenient.

[0022] It should be noted that the mounting component 2 also includes an abutting block that is compatible with the slot 28. When disassembling, the abutting block abuts against the slot 24. By pressing down the slot 24 with the abutting block, it overcomes the elastic force of the spring 25 and retracts into the groove 23, so that the insert 21 can be easily pulled out from the docking groove 22, which facilitates the disassembly and maintenance of the device.

[0023] The locking block 24 extends to one end of the outer side of the insert block 21 and is set in a triangular block structure. This structural design allows the locking block 24 to be squeezed back into the groove 23 more smoothly when the insert block 21 is inserted into the mating groove 22, further improving the convenience of installation.

[0024] The surface of the wear-resistant body 12 is provided with several arc-shaped grooves 3, which are distributed along the running direction of the wire rope. The arc-shaped grooves 3 are filled with grease. During the operation of the wire rope, the grease can continuously lubricate the wire rope, further reducing the coefficient of friction between the wire rope and the wear-resistant body 12 and reducing wear.

[0025] The outer side wall of the wear-resistant body 12 is provided with reinforcing ribs 4. The reinforcing ribs 4 can enhance the structural strength of the wear-resistant body 12, making it less prone to deformation and damage during long-term use, and ensuring the stability of the wear-resistant effect.

[0026] Working principle and process: When installing this device, first align the insert 21 with the mating groove 22 on the mounting base 1, then push the wear-resistant body 12 towards the mounting base 1. During the insertion of the insert 21 into the mating groove 22, the locking block 24 is squeezed by the inner wall of the mounting base 1, overcoming the elastic force of the spring 25 and retracting into the groove 23. When the insert 21 is fully inserted into the mating groove 22, the locking block 24 pops out under the action of the spring 25 and locks into the locking groove 28, completing the installation and fixing of the wear-resistant body 12 and the mounting base 1. Install the mounting base 1 on the bar screen body with fixing bolts, and the device can be put into use.

[0027] During use, the wire rope runs in the U-shaped groove of the wear-resistant body 12. The wear-resistant layer reduces the direct friction between the wire rope and the wear-resistant body 12, and the grease in the arc groove 3 continuously lubricates the wire rope, further reducing wear.

[0028] When the device needs to be disassembled for maintenance or replacement, use the abutment block to press down the locking block 24, causing the locking block 24 to retract into the groove 23. Then, pull the wear-resistant body 12 outward to pull the insert 21 out of the mating groove 23, thus completing the disassembly operation.
