Description

Technical Field

[0001] The present invention relates to the technical field of grinding equipment, and particularly relates to a device for grinding and removing rust from bridge steel cables. Background Art

[0002] In scenic areas, there are often steel cable bridges for tourists to walk on. Such bridges mainly consist of key components such as steel cables, columns, and bridge decks. The bridge deck is fixed to the bridge, and the bridge is firmly supported by columns and steel cables. Especially on one side of the bridge, usually two steel cables cooperate to share the gravity. However, due to long-term exposure to the natural environment, the surface of the steel cables is extremely prone to rust after being exposed to wind and rain. To maintain the performance of the steel cables and ensure the safety of the bridge, workers need to hold a grinding machine and carefully grind the rusty parts. The grinding machine mainly grinds the steel cables by driving a grinding head to rotate with an electric motor. When grinding two steel cables on the same side, tools are needed to separate the steel cables that are in contact with each other, and then grind the contacting steel cables. After grinding, paint or maintenance oil is evenly applied to the surface of the steel cables to build a protective layer, effectively preventing further corrosion of the steel cables and extending their service life.

[0003] When grinding the contact surface of two steel cables, first, a separating tool is used to contact the steel cables, separate the two steel cables, and firmly fix it on the steel cables to prevent the tool from falling out of the gap between the steel cables during grinding. After fixation, the grinding operation can be carried out. After grinding, the grinding machine needs to be moved away first, then the fixation state between the tool and the steel cables is released, and finally the tool is taken out from between the two steel cables. The whole process has many steps and complex operations, and there is a need to further optimize the grinding process of the contact surface of the two steel cables. Therefore, the present application provides a device for grinding and removing rust from bridge steel cables to meet this need. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a device for grinding and removing rust from bridge steel cables to solve the problems of many steps and complex operations in the grinding process of the contact surface of two steel cables.

[0005] To solve the above technical problem, the present invention provides the following technical solutions:

[0006] A device for grinding and removing rust from bridge steel cables, including a holding mechanism, in which an electric motor and a reciprocating component are arranged, and further includes:

[0007] A grinding mechanism, the grinding mechanism includes a fixed rod fixed at the output end of the holding mechanism, brush hair assemblies are arranged at the top and bottom of the fixed rod, an auxiliary component is arranged at the end of the holding mechanism, the auxiliary component includes a housing fixed at the end of the holding mechanism, through grooves communicating with the inside of the housing are opened at the top and bottom of the housing, and the brush hair assemblies are located in the through grooves;

[0008] When polishing the surface of the steel cable, the housing fits on the surface of the steel cable, and the brush assembly is driven by a motor and a reciprocating assembly to polish the surface of the steel cable. When polishing the contact surface between two steel cables, the two steel cables are separated by the housing. After separation, the contact surface between the two steel cables is polished by the brush assembly.

[0009] Preferably, the brush assembly includes several rows of thick bristles and fine bristles, and the fine bristles are located between two adjacent rows of thick bristles.

[0010] Preferably, positioning grooves I are provided at both the top and bottom of the housing. When polishing the surface of the steel cable, the positioning grooves I are used to position the housing.

[0011] Preferably, a positioning groove II is provided in the middle of the positioning groove I. When polishing the contact surface between two steel cables, the positioning groove II is used to position the steel cables.

[0012] Preferably, two inclined guiding surfaces I and II are provided at the end of the housing. The guiding surfaces I and II are connected, and the two guiding surfaces I are symmetrically arranged up and down about the middle of the housing, and the two guiding surfaces II are symmetrically arranged up and down about the middle of the housing. The guiding surface II is located between the guiding surface I and the positioning groove I.

[0013] Preferably, the inclination angle of the guiding surface I is smaller than that of the guiding surface II, and an arc surface II is provided between the two guiding surfaces I.

[0014] Preferably, a plurality of strip-shaped grooves communicating with the inside of the housing are provided on the guiding surface II, and a slope I is provided on the side surface of the inner wall of the strip-shaped groove. The slope I is used to reduce the contact area between the guiding surface II and the steel cable.

[0015] Preferably, a slope II is provided on the side surface of the inner wall of the strip-shaped groove, and guiding surfaces III symmetric about the housing are provided on the side of the inner wall of the housing away from the fixed rod. Both the slope II and the guiding surface III are used to guide the polishing waste to be discharged from the strip-shaped groove.

[0016] Preferably, an arc surface I is provided at the edge of the positioning groove I. When polishing the surface of the steel cable, the arc surface I is used for guiding when the housing moves along the steel cable. A vertical surface is provided on the side of the housing. After polishing the contact surface between two steel cables and pulling out the housing from between the two steel cables, the arc surface I is used for guiding when rotating the housing. After the housing rotates, the vertical surface contacts the steel cable.

[0017] Preferably, a guiding hole is provided at the end of the fixed rod away from the holding mechanism, and a guiding column is slidably connected in the guiding hole. The end of the guiding column away from the fixed rod is fixed to the inner wall of the housing.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above solution, by setting a holding mechanism, a fixing rod, a brush assembly and a housing, when polishing the surface of the steel cable, the housing fits on the surface of the steel cable. The brush assembly is driven by a motor and a reciprocating assembly to polish the surface of the steel cable. When polishing the contact surface between two steel cables, the two steel cables are separated by the housing. After separation, the brush assembly polishes the contact surface between the two steel cables, and there is no need to use external tools to separate the steel cables, making the operation more convenient.

[0020] By setting coarse bristles and fine bristles, during the polishing of the steel cable, the removal of harder substances is achieved by the coarse bristles, and the fine polishing of the surface of the steel cable is achieved by the fine bristles. Secondly, the coarse bristles can also support the fine bristles to prevent the fine bristles from bending during the polishing process, ensuring the polishing effect of the brush assembly.

[0021] By setting the first positioning groove, when polishing the surface of the steel cable, the steel cable is located in the first positioning groove, enabling the housing to slide stably along the direction of the steel cable and improving the stability during polishing.

[0022] By setting the second positioning groove, when polishing the contact position between two steel cables, after the housing is inserted between the two steel cables, the steel cables can be clamped in the second positioning groove to achieve the positioning of the steel cables, making the housing move more stably along the direction of the steel cable and improving the polishing effect.

[0023] By setting the first guiding surface and the second guiding surface, when the housing is inserted between two steel cables, first, through the first guiding surface with a smaller inclination, the housing is inserted between the two steel cables more labor - saving. Then, when pressing down again, the steel cables contact the second guiding surface. Through the second guiding surface with a larger inclination, the two steel cables are separated from each other, achieving the rapid separation of the steel cables.

[0024] By setting the strip - shaped groove and the first inclined surface, when the steel cable contacts the second guiding surface, the strip - shaped groove makes the contact area between the steel cable and the second guiding surface smaller, reducing the friction at the contact position and facilitating the insertion of the housing between the two steel cables. The first inclined surface further reduces the contact area between the steel cable and the second guiding surface, further reducing the friction at the contact position.

[0025] By setting the second inclined surface and the third guiding surface, when polishing the contact position between two steel cables, at this time the housing is in a vertical state. The waste generated during polishing can be quickly discharged from the strip - shaped groove through the guidance of the second inclined surface and the third guiding surface, preventing the waste from accumulating on the inner wall of the housing and affecting subsequent polishing.

[0026] By setting the third guiding surface and the vertical surface, after polishing the contact position between two steel cables is completed, when rotating the housing, through the guidance of the third guiding surface, the housing can rotate more smoothly. When the vertical surface of the housing contacts the steel cable, pulling the housing upward, the vertical surface is smoother, making it more labor - saving to pull the housing upward.

[0038] Generally, terms can be understood, at least in part, from their use in context. For example, at least in part depending on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or can be used to describe a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood as not necessarily intended to convey a set of exclusive factors, but rather, at least in part depending on the context, can allow for the existence of other factors that are not necessarily explicitly described.

[0039] As Figures 1-6 shown, an embodiment of the present invention provides a bridge steel cable grinding and rust removal device, including a holding mechanism 1. A motor and a reciprocating assembly are arranged inside the holding mechanism 1. The motor is electrically connected to an external power source through a wire, and further includes:

[0040] A grinding mechanism 2, the grinding mechanism 2 includes a fixed rod 3 fixed to the output end of the holding mechanism 1. The reciprocating assembly is mainly composed of a crank, a connecting rod, and a slider. The crank is connected to the output shaft of the motor. One end of the connecting rod is hinged to the crank, and the other end is hinged to the slider. The slider extends out of the holding mechanism 1. The motor drives the crank to make a circular motion, and the crank drives the slider to make a reciprocating linear motion on a linear guide through the connecting rod, thereby driving the fixed rod 3 to reciprocate. The end of the fixed rod 3 is inserted into the output end of the holding mechanism 1 and fixed by screws. Brush assemblies 4 are arranged at the top and bottom of the fixed rod 3. An auxiliary assembly 7 is arranged at the end of the holding mechanism 1. The auxiliary assembly 7 includes a housing 8 fixed to the end of the holding mechanism 1. An installation seat is arranged at the end of the housing 8. The housing 8 is also fixed to the holding mechanism 1 through the installation seat by screws. Through grooves 12 communicating with the inside of the housing 8 are opened at the top and bottom of the housing 8. The brush assemblies 4 are located in the through grooves 12;

[0041] When grinding the surface of the steel cable, the housing 8 is attached to the surface of the steel cable, and the brush assemblies 4 are driven by the motor and the reciprocating assembly to grind the surface of the steel cable. When grinding the contact surface between two steel cables, the two steel cables are separated by the housing 8. After separation, the contact surface between the two steel cables is ground by the brush assemblies 4. When the two steel cables support the bridge together, the circumferential surfaces of the two steel cables will come into contact, thus generating a contact surface, and when the two steel cables are supporting, the two steel cables approach each other, and the force between them approaching each other is relatively large.

[0042] As Figure 4 shown, in this embodiment, the brush assembly 4 includes several rows of thick bristles 5 and thin bristles 6. The thin bristles 6 are located between two adjacent rows of thick bristles 5. When grinding the steel cable, the thick bristles 5 are mainly used to remove the harder impurities on the surface of the steel cable, and the thin bristles 6 are mainly responsible for finely grinding the surface of the steel cable, realizing the division of labor in the grinding process. The combination of rough grinding and fine grinding can effectively improve the grinding effect. At the same time, the thick bristles 5 can support the thin bristles 6 to prevent the thin bristles 6 from being overly bent during the grinding process, ensuring the grinding performance of the brush assembly 4.

[0043] As Figure 5 shown, in this embodiment, positioning grooves 9 are provided at both the top and bottom of the housing 8. When grinding the surface of the steel cable, the positioning grooves 9 are used to position the housing 8 so that the steel cable is located within the positioning grooves 9, ensuring that the housing 8 can slide stably along the direction of the steel cable, improving the stability during the grinding process, and further enhancing the grinding quality.

[0044] As Figure 5 shown, in this embodiment, a positioning groove 10 is provided in the middle of the positioning groove 9. When grinding the contact surface between two steel cables, the positioning groove 10 is used to position the steel cables. After the housing 8 is inserted between the two steel cables, the steel cables can be clamped in the positioning groove 10, making the housing 8 more stable when moving along the direction of the steel cable and further improving the grinding effect on the contact surface of the steel cables.

[0045] As Figure 5 shown, in this embodiment, two inclined guiding surfaces 13 and guiding surfaces 14 are provided at the end of the housing 8. The guiding surfaces 13 and the guiding surfaces 14 are connected. The two guiding surfaces 13 are symmetrically arranged up and down about the middle of the housing 8, and the two guiding surfaces 14 are symmetrically arranged up and down about the middle of the housing 8. The guiding surfaces 14 are located between the guiding surfaces 13 and the positioning groove 9. The guiding surfaces 13 and the guiding surfaces 14 are used for guiding when the housing 8 is inserted between two steel cables, making it easier to insert the housing 8.

[0046] As Figure 5 shown, in this embodiment, the inclination angle of the guiding surface 13 is smaller than the inclination angle of the guiding surface 14. An arc surface 22 is provided between the two guiding surfaces 13. When the housing 8 is inserted between two steel cables, it is first guided by the arc surface 22, facilitating the insertion of the housing 8 between the two steel cables. Then, the guiding surface 13 with a smaller inclination contacts the steel cable, and then the steel cable contacts the guiding surface 14. The guiding surface 13 with a smaller inclination can more easily insert the housing 8 between the two steel cables initially. The guiding surface 14 with a larger inclination can separate the two steel cables from each other, realizing the rapid separation of the steel cables, reducing the operation difficulty, and improving the work efficiency.

[0047] As Figure 3 、Figure 5 and Figure 6 As shown in Figure 5 and Figure 6 , in this embodiment, a plurality of strip-shaped grooves 15 communicating with the inside of the housing 8 are formed in the second guiding surface 14. The strip-shaped grooves 15 can not only reduce the contact area between the second guiding surface 14 and the steel cable, reduce the friction force at the contact position, but also enable waste materials to be discharged from the strip-shaped grooves 15, avoiding the accumulation of waste materials in the housing 8. A first inclined surface 16 is provided on the side surface of the inner wall of the strip-shaped groove 15, and the first inclined surface 16 is used to further reduce the contact area between the second guiding surface 14 and the steel cable, thereby further reducing the friction force between the steel cable and the second guiding surface 14.

[0048] As Figure 3 and Figure 6 As shown in Figure 3 and Figure 6 , in this embodiment, a second inclined surface 21 is provided on the side surface of the inner wall of the strip-shaped groove 15, and a third guiding surface 17 symmetrical about the housing 8 is provided on the side of the inner wall of the housing 8 away from the fixing rod 3. Both the second inclined surface 21 and the third guiding surface 17 are used to guide the grinding waste materials to be discharged from the strip-shaped grooves 15. When grinding the contact position of the two steel cables, at this time, the housing 8 is in a vertical state. The second inclined surface 21 prevents the waste materials from blocking at the strip-shaped grooves 15, and the third guiding surface 17 prevents the waste materials from accumulating inside the housing 8. The guiding grinding waste materials are also discharged from the strip-shaped grooves 15, preventing the waste materials from affecting the subsequent grinding operation and ensuring the continuous and efficient progress of the grinding work.

[0049] As Figure 5 As shown in Figure 5 , in this embodiment, an arc-shaped surface 11 is provided at the edge of the first positioning groove 9. When grinding the surface of the steel cable, the arc-shaped surface 11 is used for guiding when the housing 8 moves along the steel cable, avoiding jamming between the housing 8 and the steel cable and making the movement of the housing 8 smoother. A vertical surface 18 is provided on the side surface of the housing 8, and the surface of the vertical surface 18 is smoother, reducing the friction force between the housing 8 and the steel cable. After grinding the contact surface of the two steel cables, when pulling out the housing 8 from between the two steel cables, the arc-shaped surface 11 is used for guiding when rotating the housing 8. After the housing 8 rotates, the vertical surface 18 contacts the steel cable. After the steel cable moves from the first positioning groove 9 to the vertical surface 18, the vertical surface 18 will not block the steel cable, making it easier to pull out the housing 8 from between the two steel cables. The arc-shaped surface 11 plays a guiding role at different stages, making the operation smoother. The vertical surface 18 is smoother, reducing the resistance when pulling out the housing 8 and making the pulling-out operation more labor-saving.

[0050] As Figure 3 and Figure 6As shown in the figure, in this embodiment, a guiding hole 19 is provided at one end of the fixing rod 3 away from the holding mechanism 1. A guiding column 20 is slidably connected in the guiding hole 19. One end of the guiding column 20 away from the fixing rod 3 is fixed to the inner wall of the housing 8. During the reciprocating movement of the fixing rod 3, the guiding hole 19 and the guiding column 20 can play a guiding role, ensuring the stability and accuracy of the movement of the fixing rod 3, thereby ensuring the accuracy of the grinding position of the brush assembly 4 and improving the grinding effect.

[0051] Working principle: Before grinding the surface of the steel cable, move the housing 8 close to the steel cable so that the steel cable falls into the first positioning groove 9. Through the limitation of the first positioning groove 9, stable fitting between the housing 8 and the steel cable is achieved, enabling the housing 8 to slide stably along the steel cable.

[0052] During grinding, start the motor in the holding mechanism 1. The motor drives the reciprocating assembly to reciprocate. The reciprocating assembly drives the fixing rod 3 to reciprocate. The fixing rod 3 drives the brush assembly 4 to grind the surface of the steel cable. During grinding, the thick bristles 5 remove hard impurities, and the fine bristles 6 are responsible for fine grinding. The thick bristles 5 also provide support for the fine bristles 6 to prevent the fine bristles 6 from bending excessively.

[0053] Before grinding the contact surface between two steel cables, place the housing 8 vertically, align the second arc surface 22 of the housing 8 with the middle of the two steel cables. Through the guidance of the second arc surface 22, the first guiding surface 13 first contacts the steel cable, and with a small inclination angle, it helps the housing 8 to be initially inserted. During the downward pressing process, the steel cable contacts the second guiding surface 14, and the larger inclination angle makes the steel cables move away from each other for separation. During this process, the strip groove 15 and the first inclined surface 16 reduce the contact friction. After the steel cable is stuck in the second positioning groove 10, positioning is completed.

[0054] Start the motor again, and the brush assembly 4 grinds the contact surface of the steel cable. The waste generated during grinding is discharged from the strip groove 15 under the guidance of the second inclined surface 21 and the third guiding surface 17.

[0055] After grinding is completed, rotate the housing 8. The first arc surface 11 makes the rotation of the housing 8 smoother. When the vertical surface 18 contacts the steel cable, the housing 8 can be pulled out upward.

[0056] The present invention covers any substitutions, modifications, equivalent methods, and solutions made within the essence and scope of the present invention. To enable the public to have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention. However, those skilled in the art can fully understand the present invention even without these detailed descriptions.

[0057] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
