Description

Technical Field

[0001] The invention relates to the technical field of guardrail surface renovation and polishing, and specifically proposes a device and a processing method for renovation and polishing the surface of a corrugated beam steel guardrail. Background Art

[0002] The corrugated steel guardrail is exposed to the outdoors for a long time and is affected by ultraviolet rays, rain, salt spray and other environmental factors, which may cause defects such as rust, oxidation or coating peeling on the surface. Refurbishment and polishing can remove rust and aging layers, re-form a protective barrier, and ensure its impact resistance, structural stability and aesthetics.

[0003] At present, when polishing the surface of corrugated steel guardrails, either a handheld polisher is used or sandblasting is used. The former is labor-intensive and inefficient, while the latter requires a large amount of sandblasting consumables, is costly and easily causes dust pollution.

[0004] Therefore, there is an urgent need for a surface renovation and polishing device for a corrugated beam steel guardrail to improve the polishing efficiency and polishing quality of the guardrail, reduce the polishing cost of the guardrail and reduce dust pollution during the polishing process. Summary of the invention

[0005] In view of the above problems, an embodiment of the present invention provides a surface renovation and polishing device and a processing method for a corrugated beam steel guardrail to solve the technical problems in the related art.

[0006] In order to achieve the above-mentioned purpose, an embodiment of the present invention provides the following technical solution: a surface renovation and polishing device for a corrugated beam steel guardrail, comprising: a moving vehicle, four fixed brackets, two guiding mechanisms, a sealing cover, a polishing mechanism, a dust collection mechanism, and a driving source installed on the moving vehicle to drive the sealing cover to move.

[0007] The four fixed brackets are arranged in a rectangular shape and are fixedly connected to the mobile vehicle. An end sealing plate is slidably provided on two fixed brackets correspondingly distributed in the horizontal direction, and the upper and lower end sealing plates are symmetrically arranged. The guiding mechanism is installed on the side of the end sealing plate away from the mobile vehicle, and the two guiding mechanisms are respectively used to clamp the upper and lower sides of the guardrail. The sealing cover is slidably installed on the four fixed brackets, and the sealing cover is equipped with a push locking mechanism for pulling the two end sealing plates and the guiding mechanism to move toward the mobile vehicle when the sealing cover moves toward the end sealing plate. The polishing mechanism is installed on the sealing cover, and the dust suction mechanism is installed together with the sealing cover and the two end sealing plates.

[0008] In one possible implementation, the guiding mechanism includes three mounting seats installed in the middle of one side of the end sealing plate away from the sealing cover, two of which are located in the sealing cavity, and the other is located outside the sealing cavity. A resistance roller is installed on the mounting seat located outside the sealing cavity, and clamping seats are installed on the three mounting seats through spring rods. The clamping seats are arranged in arc shape on both sides along the length direction of the end sealing plate to facilitate the guardrail end to enter between the clamping seats on both sides. Evenly arranged balls are installed on the clamping seats, and the three clamping seats cooperate to clamp the guardrail end.

[0009] In a possible implementation, the axis of the rotating shaft is between two mounting seats located in the sealed cavity, the mounting seat located outside the sealed cavity is aligned with the axis of the rotating shaft, and a resistance roller is installed on the mounting seat located outside the sealed cavity.

[0010] In one possible implementation, the sealing cover includes a rectangular box slidably connected to four fixed brackets, the fixed brackets are in an I-shape, and the outer walls at the top corners of the rectangular box are provided with guide grooves that slide with the fixed brackets. Insert plates are installed at the upper and lower ends of the rectangular box, and slots that are plugged into the insert plates are opened on the upper and lower end sealing plates. Side panels that cooperate with the upper and lower end sealing plates are installed on both sides of the rectangular box arranged along its width direction, and the side of the side plate close to the guardrail is wavy in shape that cooperates with the side wall of the guardrail.

[0011] In one possible implementation, the push-locking mechanism includes a seesaw rotatably connected to a fixed bracket, a waist-shaped groove is provided at one end of the seesaw near the end sealing plate, a guide column inserted into the waist-shaped groove is rotatably connected to the end sealing plate, and a push roller corresponding to the seesaw is rotatably connected to the sealing cover through an ear plate, the push roller is used to push the seesaw when the sealing cover moves toward the end sealing plate, and a reset spring is installed between the end sealing plate and the fixed bracket.

[0012] In one possible implementation, the polishing mechanism is installed between the upper and lower end surfaces of the side of the sealing cover close to the end sealing plate. The polishing mechanism includes a rotating shaft rotatably connected between the upper and lower side walls of the sealing cover. A driving component (such as a motor) for driving the rotating shaft to rotate is installed on the sealing cover. The side wall of the rotating shaft is installed with grinding heads evenly arranged along its circumference through an elastic component. The horizontal cross-section of the grinding head is arc-shaped and the vertical cross-section is wavy. The side of the grinding head away from the rotating shaft is a stainless steel nylon brush (not shown in the figure). When the sealing cover moves toward the guardrail, the corresponding grinding head is driven to elastically contact the guardrail.

[0013] In one possible implementation, the elastic component includes a telescopic rod and a spring 1 that are symmetrically arranged up and down and installed between the grinding head and the rotating shaft. The two springs 1 are located between the two telescopic rods. The telescopic rod and the spring 1 cooperate to push the grinding head and the guardrail elastically tightly.

[0014] In one possible implementation, the dust collection mechanism includes two end sealing plates and two side plates, each of which is located on one side of the sealing cavity. The dust collection box on the side plate is wavy in shape, and is provided with a plurality of evenly distributed dust collection holes. A telescopic tube is installed between two adjacent dust collection boxes, and the telescopic tube contracts when the sealing cover moves toward the end sealing plate. Dust collection tubes that penetrate the sealing cover are installed on the two dust collection boxes installed on the side plates, and a dust collection assembly (an existing vacuum cleaner) connected to the dust collection tube is provided on the mobile vehicle.

[0015] In one possible implementation, the mobile vehicle is equipped with an auxiliary support assembly for auxiliary supporting the two end sealing plates. The auxiliary support assembly includes four support frames installed on the mobile vehicle and arranged in a rectangular shape. The support frames on the upper and lower sides are arranged symmetrically. The end of the support frame away from the mobile vehicle is slidably connected to the end sealing plate and the support frame is inclined.

[0016] The present invention also provides a method for refurbishing and polishing the surface of a corrugated beam steel guardrail, comprising the following steps: S1, sleeve installation: respectively clamping the upper and lower guide mechanisms on the upper and lower ends of the guardrail, and the guide mechanisms elastically clamp the upper and lower side walls of the guardrail.

[0017] S2, sealing locking: the driving source drives the sealing cover to move toward the end sealing plate. During the movement, the sealing cover pulls the two end sealing plates and the guide mechanism toward the moving vehicle through the push-locking mechanism, so that the end sealing plate drives the guide mechanism and the guardrail to press against each other. At the same time, the sealing cover and the upper and lower end sealing plates and the guardrail form a sealing cavity.

[0018] S3, polishing and dust collection: the driving assembly drives the rotating shaft to rotate, and the rotating shaft drives the grinding head to rotate to polish the surface of the guardrail. The dust collection assembly is started during polishing, and the dust collection assembly absorbs the dust generated by polishing through the dust collection pipe, dust collection box and dust collection hole. The dust collection box is distributed in the gap of the sealing chamber close to the guardrail to effectively remove the dust that is about to overflow the sealing chamber. The mobile vehicle drives the polishing mechanism, the sealing cover, and the end sealing plate to move along the length direction of the guardrail and polish the guardrail until the guardrail polishing is completed.

[0019] The above one or more technical solutions in the embodiments of the present invention have at least one of the following beneficial effects: 1. A corrugated beam steel guardrail surface renovation and polishing device designed by the present invention realizes the functions of sealing the polishing part of the guardrail and automatic mechanical polishing through a sealing cover, two end sealing plates and a polishing mechanism and a dust suction mechanism, thereby improving the polishing efficiency of the guardrail, while avoiding the problems of large consumables consumption and high polishing cost when polishing the guardrail by traditional sandblasting. The polishing head in the polishing mechanism polishes in contact with the guardrail through elastic adaptive force, avoiding the problem of the polishing head getting stuck when passing through the joint of the two guardrails. During the polishing process, the upper and lower guide mechanisms cooperate to guide the movement of the polishing mechanism, so that the polishing mechanism always polishes in contact with the guardrail, greatly improving the polishing quality of the guardrail.

[0020] 2. When the sealing cover of the present invention contacts the end sealing plate, the sealing cover can not only lock the end sealing plate through the push locking mechanism, but also form a sealed cavity with the upper and lower end sealing plates and the guardrail to prevent the dust generated during polishing from flying around and affecting the working environment. Then, the dust generated during polishing is adsorbed and removed through the dust suction mechanism.

[0021] 3. In the present invention, the dust suction mechanism is arranged on the sealing cover and the two end sealing plates and is located on the side of the sealing cavity close to the guardrail, so that the dust suction mechanism can effectively remove the dust that is about to overflow from the sealing cavity at the gap of the sealing cavity close to the guardrail, further improving the dust removal effect during the polishing of the guardrail.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] See also Figure 1 and Figure 4 A surface renovation and polishing device for a corrugated steel guardrail includes: a mobile vehicle, four fixed brackets 1, two guide mechanisms 3, a sealing cover 4, a polishing mechanism 7, a dust suction mechanism 8, and a driving source 6 installed on the mobile vehicle to drive the sealing cover 4 to move.

[0033] See also Figure 1 and Figure 4 , four fixed brackets 1 are arranged in a rectangular shape and are fixedly connected to the mobile vehicle, and end sealing plates 2 are slidably provided on two fixed brackets 1 correspondingly distributed in the horizontal direction, and the upper and lower end sealing plates 2 are symmetrically arranged; a guiding mechanism 3 is installed on the side of the end sealing plate 2 away from the mobile vehicle, and the two guiding mechanisms 3 are respectively used to clamp the upper and lower sides of the guardrail 9; a sealing cover 4 is slidably installed on the four fixed brackets 1, and a pushing and locking mechanism 5 is installed on the sealing cover 4, which pulls the two end sealing plates 2 and the guiding mechanism 3 to move toward the mobile vehicle when it moves toward the end sealing plate 2; a polishing mechanism 7 is installed on the sealing cover 4, and a dust suction mechanism 8 is installed on the sealing cover 4 and the two end sealing plates 2.

[0034] In the initial state, the sealing cover 4 and the end sealing plate 2 are in a distant state, so that the guardrail 9 can enter between the upper and lower guide mechanisms 3 and the sealing cover 4, and at the same time, the guide mechanism 3 can be stuck at the upper and lower ends of the guardrail 9. Then the driving source 6 (such as a cylinder, etc.) drives the sealing cover 4 to move toward the end sealing plate 2. During the movement, the sealing cover 4 pushes the locking mechanism 5 to pull the two end sealing plates 2 and the guide mechanism 3 toward the moving vehicle, so that the end sealing plate 2 drives the guide mechanism 3 to press against the guardrail 9, so that the guide mechanism 3 can stably move and guide along the guardrail 9.

[0035] When the sealing cover 4 contacts the end sealing plate 2, the sealing cover 4 forms a sealing cavity with the upper and lower end sealing plates 2 and the guardrail 9, thereby preventing the dust generated during polishing from flying around and affecting the working environment. At this time, the polishing mechanism 7 contacts the side wall of the guardrail 9, and then the polishing mechanism 7 polishes the guardrail 9. At the same time, the moving vehicle drives the sealing cover 4 and the polishing mechanism 7 to move along the guardrail 9. The guiding mechanism 3 guides the movement of the sealing cover 4 and the upper and lower end sealing plates 2 along the guardrail 9, thereby improving the accuracy of the polishing process of the guardrail 9 by the polishing mechanism 7. At the same time, the dust collecting mechanism 8 absorbs and removes the dust generated during polishing. It should be noted that during the movement of the guiding mechanism 3, the fixed bracket 1, the sealing cover 4 and the polishing mechanism 7, the vertical plate fixedly connected between the moving vehicle and the fixed bracket 1 can be adaptively moved on the moving vehicle, so that there is enough moving space between the moving vehicle and the fixed bracket 1.

[0036] To sum up, the sealing cover 4, the two end sealing plates 2, the polishing mechanism 7 and the dust suction mechanism 8 cooperate to achieve the function of sealing and polishing the undisassembled guardrail 9, which is more environmentally friendly, saves more materials, and has higher polishing accuracy. It avoids the problem of serious material loss and environmental pollution when polishing the undisassembled guardrail 9 by traditional sand blasting.

[0037] See also Figure 1 , Figure 2 and Figure 3 The guiding mechanism 3 includes three mounting seats 30 installed in the middle of one side of the end sealing plate 2 away from the sealing cover 4, wherein two mounting seats 30 are located in the sealing cavity, and the other mounting seat 30 is located outside the sealing cavity. The mounting seat 30 located outside the sealing cavity is installed with a resisting roller, and the three mounting seats 30 are all installed with a clamping seat 32 through a spring rod 31. The clamping seats 32 are arranged in an arc shape on both sides along the length direction of the end sealing plate 2, so that the end of the guardrail 9 can enter between the clamping seats 32 on both sides. The clamping seats 32 are installed with evenly arranged balls, and the three clamping seats 32 cooperate to clamp the end of the guardrail 9.

[0038] The clamping seats 32 on both sides are sleeved on the ends of the guardrail 9. The clamping seats 32 on both sides clamp the guardrail 9 under the elastic force of the spring rod 31. At the same time, the elastic clamping of the clamping seats 32 on the guardrail 9 can prevent the clamping seats 32 from being difficult to move when encountering the joint of two guardrails 9; when the mobile vehicle moves, the clamping seats 32 move along the guardrail 9 to guide the polishing process of the guardrail 9.

[0039] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The sealing cover 4 includes a rectangular box 40 slidably connected to four fixed brackets 1, the fixed bracket 1 is in an I-shape, and the outer walls at the top corners of the rectangular box 40 are provided with guide grooves that slide with the fixed bracket 1. The inside of the rectangular box 40 is provided with reinforcements for strengthening the structural strength at its top corners. The upper and lower ends of the rectangular box 40 are installed with plug plates 41, and the upper and lower end sealing plates 2 are provided with slots 42 that are plugged into the plug plates 41. Side plates 43 that cooperate with the upper and lower end sealing plates 2 are installed on both sides of the rectangular box 40 arranged along its width direction, and the side of the side plate 43 close to the guardrail 9 is wavy in shape to cooperate with the side wall of the guardrail 9.

[0040] When the driving source 6 drives the sealing cover 4 to move toward the end sealing plate 2, the side plate 43 moves along the width direction of the upper and lower end sealing plates 2, and the sealing cover 4 pulls the end sealing plate 2 toward the moving vehicle through the push-locking mechanism 5 until the abutting roller on the mounting seat 30 located outside the sealing cavity abuts against the guardrail 9. At this time, the plug plate 41 is inserted into the slot 42, and the plug plate 41 cooperates with the slot 42 to support the end of the sealing cover 4, thereby avoiding the problem of insufficient supporting force at the end of the sealing cover 4 equipped with the polishing mechanism 7.

[0041] See also Figure 4 , Figure 5 and Figure 6 The push-locking mechanism 5 includes a seesaw 50 rotatably connected to the fixed bracket 1, a waist-shaped groove 51 is provided at one end of the seesaw 50 close to the end sealing plate 2, a guide column inserted into the waist-shaped groove 51 is rotatably connected to the end sealing plate 2, and a push roller 52 corresponding to the seesaw 50 is rotatably connected to the sealing cover 4 through an ear plate. The push roller 52 is used to push the seesaw 50 when the sealing cover 4 moves toward the end sealing plate 2, and a reset spring 53 is installed between the end sealing plate 2 and the fixed bracket 1.

[0042] When the sealing cover 4 moves toward the end sealing plate 2, the sealing cover 4 drives the resistance roller 52 to press against one end of the seesaw 50, so that the seesaw 50 rotates along the rotating connection between it and the fixed bracket 1, and the other end of the seesaw 50 pulls the guide column during the rotation, and the guide column moves along the waist groove 51. At the same time, the guide column drives the end sealing plate 2 to move toward the sealing cover 4, so that the resistance roller on the mounting seat 30 located outside the sealing cavity is in contact with the guardrail 9, and the sealing cover 4 and the end sealing plate 2 are plugged into the plug plate 41 and the slot 42 to lock the position of the guide mechanism 3, so that the guide mechanism 3 can guide the movement of the sealing cover 4 and the polishing mechanism 7 later, thereby improving the accuracy of polishing the guardrail 9.

[0043] See also Figure 1 , Figure 2 and Figure 3 The polishing mechanism 7 is installed between the upper and lower end surfaces of the side of the sealing cover 4 close to the end sealing plate 2. The polishing mechanism 7 includes a rotating shaft 70 rotatably connected between the upper and lower side walls of the sealing cover 4. A driving component (such as a motor) for driving the rotating shaft 70 to rotate is installed on the sealing cover 4. The side wall of the rotating shaft 70 is installed with grinding heads 72 evenly arranged along its circumference through an elastic component 71. The horizontal cross-section of the grinding head 72 is arc-shaped and the vertical cross-section is wavy. The side of the grinding head 72 away from the rotating shaft 70 is a stainless steel nylon wire brush (not shown in the figure). When the sealing cover 4 moves toward the guardrail 9, the corresponding grinding head 72 is driven to elastically contact the guardrail 9.

[0044] See also Figure 3 The elastic component 71 includes a telescopic rod 710 and a spring 711 symmetrically arranged up and down and installed between the grinding head 72 and the rotating shaft 70. The two springs 711 are located between the two telescopic rods 710. The telescopic rod 710 and the spring 711 cooperate to push the grinding head 72 and the guardrail 9 elastically.

[0045] See also Figure 2 and Figure 3 The axis of the rotating shaft 70 is between the two mounting seats 30 located in the sealed cavity, and the mounting seat 30 located outside the sealed cavity is aligned with the axis of the rotating shaft 70, so that the contact part where the corresponding grinding head 72 grinds the guardrail 9 is located between the two mounting seats 30 in the sealed cavity, so that the guiding mechanism 3 can clamp and guide the guardrail 9 without affecting the grinding of the guardrail 9 by the grinding head 72.

[0046] When the sealing cover 4 moves toward the end sealing plate 2, it drives the polishing mechanism 7 to move toward the guardrail 9 until the grinding head 72 contacts the guardrail 9. The grinding head 72 elastically contacts the guardrail 9 through the elastic force of the spring 1 711, so that the grinding head 72 can make a transition when it encounters the joint of two guardrails 9. After the guide mechanism 3 is clamped on the guardrail 9, the driving assembly drives the rotating shaft 70 to rotate, and the rotating shaft 70 drives the grinding head 72 to rotate to polish the surface of the guardrail 9.

[0047] See also Figure 4 The dust collection mechanism 8 includes two dust boxes 80 installed on one side of the two end sealing plates 2 and the two side plates 43 located in the sealing cavity. The dust boxes 80 on the side plates 43 are wavy in shape, and a plurality of dust collection holes arranged evenly are opened on the dust boxes 80. A telescopic tube 81 is installed between two adjacent dust boxes 80. When the sealing cover 4 moves toward the end sealing plate 2, the telescopic tube 81 contracts. A dust collection tube 82 that penetrates the sealing cover 4 is installed on the two dust boxes 80 installed on the side plates 43, and a dust collection assembly (which is an existing vacuum cleaner) connected to the dust collection tube 82 is provided on the mobile vehicle.

[0048] The dust suction component is started during polishing, and absorbs the dust generated by polishing through the dust suction pipe 82, the dust collecting box 80 and the dust suction hole, so as to prevent the dust generated during polishing from flying around and polluting the environment.

[0049] See also Figure 1 , Figure 2 and Figure 4 The mobile vehicle is provided with an auxiliary support assembly 20 for auxiliary supporting the two end sealing plates 2. The auxiliary support assembly 20 includes four support frames 201 installed on the mobile vehicle and arranged in a rectangular shape. The support frames 201 on the upper and lower sides are arranged symmetrically. The end of the support frame 201 away from the mobile vehicle is slidably connected to the end sealing plate 2 and the support frame 201 is inclined. When the end sealing plate 2 moves, the end sealing plate 2 moves along the support frame 201. The support frame 201, the end sealing plate 2, the fixed bracket 1 and the mobile vehicle form a triangle, thereby avoiding the fixed bracket 1 and the end of the end sealing plate 2 away from the mobile vehicle from being in a cantilever beam state, thereby improving the stability of the end sealing plate 2 and the fixed bracket 1.

[0050] See also Figure 1-Figure 6 The present invention also provides a method for surface renovation and polishing of a corrugated beam steel guardrail, comprising the following steps: S1, sleeve installation: the upper and lower guide mechanisms 3 are respectively clamped on the upper and lower ends of the guardrail 9, and the guide mechanisms 3 elastically clamp the upper and lower side walls of the guardrail 9.

[0051] S2, sealing locking: the driving source 6 drives the sealing cover 4 to move toward the end sealing plate 2. During the movement, the sealing cover 4 pulls the two end sealing plates 2 and the guiding mechanism 3 toward the moving vehicle through the pushing locking mechanism 5, so that the end sealing plate 2 drives the guiding mechanism 3 to press against the guardrail 9. At the same time, the sealing cover 4 forms a sealing cavity with the upper and lower end sealing plates 2 and the guardrail 9.

[0052] S3, polishing and dust collection: the driving assembly drives the rotating shaft 70 to rotate, and the rotating shaft 70 drives the grinding head 72 to rotate to polish the surface of the guardrail 9. The dust collection assembly is started during polishing. The dust collection assembly absorbs the dust generated by polishing through the dust collection pipe 82, the dust collection box 80 and the dust collection hole. The dust collection box 80 is distributed in the gap of the sealing cavity close to the guardrail 9 to effectively remove the dust that is about to overflow the sealing cavity. The mobile vehicle drives the polishing mechanism 7, the sealing cover 4, and the end sealing plate 2 to move along the length direction of the guardrail 9 and polish the guardrail 9 until the polishing of the guardrail 9 is completed.
