Description

Technical Field

[0001] The present application relates to the technical field of guardrail plate processing and feeding, and in particular to a galvanized guardrail plate feeding device. Background Art

[0002] Galvanizing of guardrails forms a dense physical barrier on their surface, which effectively isolates the guardrail body (usually steel) from direct contact with corrosive media such as air, moisture, oxygen, salt (such as snow melting agents, coastal salt spray), industrial pollutants, etc., giving it excellent corrosion resistance, thereby ensuring that it can maintain its structural integrity and protective function for a long time in harsh outdoor environments, reducing maintenance costs throughout its life cycle.

[0003] In actual operation, in order to improve production efficiency, group lifting is often adopted, that is, multiple guardrail panels are hung in series on a large lifting device through steel wire ropes, and the whole is immersed in molten zinc liquid at 450℃~480℃ to form a dense zinc-iron alloy coating on its surface to realize the galvanizing operation.

[0004] However, when the guardrail panels are lifted out of the zinc bath, the turbulence of the zinc bath, the mechanical movement of the lifting equipment, or the disturbance of hot air currents can cause the lifting device to shake, causing adjacent guardrail panels to collide during the shaking. The unsolidified zinc bath at high temperatures (450°C) forms a liquid bridge, causing adhesion between the panels. Currently, these adhered guardrail panels must be forcibly separated by manual or mechanical force. This process tears the semi-solidified zinc layer, forming irregular zinc nodules or exposed substrate scars in the peeled areas, disrupting the continuity of the coating and resulting in uneven coating, which in turn affects the protective effect. Summary of the Invention

[0005] The present application aims to solve one of the technical problems in the related art at least to a certain extent.

[0006] To this end, one purpose of the present application is to propose a galvanized feeding device for guardrail plates, which can strike the first steel rope for hoisting the guardrail plates during the process of lifting the guardrail plates. The vibration is transmitted to the guardrail plates, effectively shaking off excess zinc liquid on the surface and preventing adhesion between the plates, thereby reducing the generation of irregular zinc nodules or exposed substrate scars, and improving the uniformity of the coating and the protective effect.

[0007] To achieve the above-mentioned objectives, the first embodiment of the present application proposes a galvanized feeding device for guardrail plates, comprising a linear moving mechanism, two hanging plates, two groups of lifting mechanisms, two driving mechanisms and two striking mechanisms, wherein the linear moving mechanism is installed on the top of the workshop column; the two hanging plates are respectively connected to the slide of the linear moving mechanism, and a connecting plate is provided under each hanging plate; the two groups of lifting mechanisms are respectively arranged on the corresponding hanging plates, and the lifting mechanisms are connected to the connecting plates; a plurality of first steel ropes are provided in pairs under the connecting plates, and a guardrail plate is hung at the bottom of the first steel rope; the two driving mechanisms are respectively arranged on the corresponding connecting plates; the two striking mechanisms are respectively arranged on the corresponding connecting plates and are connected to the corresponding driving mechanisms.

[0008] The galvanized feeding device for the guardrail plate of the embodiment of the present application can strike the first steel rope for hoisting the guardrail plate during the process of lifting the guardrail plate. The vibration is transmitted to the guardrail plate, effectively shaking off excess zinc liquid on the surface and preventing adhesion between the plates, thereby reducing the generation of irregular zinc nodules or exposed substrate scars, and improving the uniformity of the coating and the protective effect.

[0009] In addition, the galvanized feeding device for guardrail plates proposed in the present application may also have the following additional technical features:

[0011] In one embodiment of the present application, the striking mechanism includes two connecting components and a striking plate, wherein the two connecting components are respectively arranged on both sides of the connecting plate and connected to the rotating shaft; the striking plate is arranged on one side of the first steel rope and connected to the connecting component.

[0012] In one embodiment of the present application, the connecting assembly includes a turntable, a sliding rod and a connecting rod, wherein the turntable is arranged at the end of the rotating shaft; one end of the connecting rod is hinged to the side wall of the connecting plate, and the other end of the connecting rod is fixedly connected to the striking plate, and a sliding groove is provided through the connecting rod; the sliding rod is eccentrically arranged on the turntable and is slidably connected to the sliding groove.

[0013] In one embodiment of the present application, the lifting mechanism includes a winding assembly, two fixed pulleys and two second steel ropes, wherein the winding assembly is installed below the hanging plate; the two fixed pulleys are symmetrically arranged on both sides of the winding assembly, and the fixed pulleys are connected to the hanging plate; one end of the second steel rope is connected to the connecting plate, and the other end of the second steel rope passes around the fixed pulley and is connected to the winding assembly.

[0014] In one embodiment of the present application, the winding assembly includes two brackets, a reel and two baffles, wherein the two brackets are respectively arranged on the two side walls of the hanging plate; the two baffles are respectively arranged on the corresponding brackets; the reel is rotatably arranged between the two baffles, and the other end of the second steel rope is fixedly arranged on the reel.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application and are not to be construed as limiting the present application. On the contrary, the embodiments of the present application include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0027] The following describes the guardrail plate galvanizing feeding device according to an embodiment of the present application with reference to the accompanying drawings.

[0028] like Figures 1 to 5 As shown, the galvanized feeding device for guardrail plates of an embodiment of the present application may include a linear moving mechanism 1, two hanging plates 2, two sets of lifting mechanisms 3, two driving mechanisms 5 and two striking mechanisms 6.

[0029] The linear motion mechanism 1 is installed on the top of the workshop column, and the two hanging plates 2 are respectively connected to the slide of the linear motion mechanism 1, and a connecting plate 7 is provided under each hanging plate 2.

[0030] It should be noted that the linear moving mechanism 1 described in this embodiment can be a crane, which is installed on the top of the workshop or installed in the workshop through a column, and the crane track is located above the zinc trough or zinc pot (a container for hot zinc solution). Two slides are slidably connected to the linear moving mechanism 1, and multiple guardrail plates can be moved above the zinc trough or zinc pot through the linear moving mechanism 1.

[0031] The two sets of lifting mechanisms 3 are respectively arranged on the corresponding hanging plates 2, and the lifting mechanisms 3 are connected to the connecting plate 7. A plurality of first steel ropes 4 are arranged in pairs below the connecting plate 7, and a guardrail plate is hung at the bottom of the first steel ropes 4.

[0032] It should be noted that the lifting mechanism 3 can control the connection plate 7 and the plurality of guardrail plates to rise or fall, thereby immersing the guardrail plates in the zinc solution and lifting the hot-dip-plated guardrail plates out of the zinc solution.

[0033] Furthermore, the two ends of the first steel rope 4 can be connected to the connecting plate 7 and the guardrail plate respectively through hooks, that is, a hook is provided at the end of the first steel rope 4. Since mounting holes are processed on the guardrail plate, the guardrail plate can be quickly hung through the hook, and the first steel ropes 4 on the two connecting plates 7 are arranged one by one, so that both ends of the guardrail plate can be hung at the same time, thereby improving the stability of the hung guardrail plate.

[0034] The two driving mechanisms 5 are respectively arranged on the corresponding connecting plates 7 ; the two striking mechanisms 6 are respectively arranged on the corresponding connecting plates 7 and connected to the corresponding driving mechanisms 5 .

[0035] It should be noted that the two driving mechanisms 5 can drive the corresponding striking mechanism 6 to strike the first steel rope 4, and use the vibration of the first steel rope 4 to transmit to the guardrail plate to shake off the excess zinc liquid on the guardrail plate. At the same time, it can also prevent adjacent guardrail plates from sticking together, effectively reducing the generation of irregular zinc nodules or exposed substrate scars, and improving the uniformity and protective effect of the coating.

[0036] In one embodiment of the present application, Figure 2 As shown, the driving mechanism 5 includes a motor 51, a driving shaft 52, two gears 53 and a rotating shaft 54, wherein the motor 51 is arranged on the side wall of the connecting plate 7; the driving shaft 52 is connected to the output end of the motor 51; the rotating shaft 54 is rotatably arranged at the lower part of the connecting plate 7 through the support plate 8; the two gears 53 are respectively arranged on the driving shaft 52 and the rotating shaft 54, and the two gears 53 are meshed and connected.

[0037] It should be noted that the support plate 8 is arranged on the connecting plate 7, the rotating shaft 54 is rotatably connected to the support plate 8, and the axis of the rotating shaft 54 is arranged along the length direction of the connecting plate 7. The motor 51 can control the rotation of the drive shaft 52, and the cooperation between the two gears 53 can drive the rotating shaft 54 to rotate.

[0038] Furthermore, if Figure 3 As shown, the striking mechanism 6 includes two connecting components 61 and a striking plate 62, wherein the two connecting components 61 are respectively arranged on both sides of the connecting plate 7 and connected to the rotating shaft 54; the striking plate 62 is arranged on one side of the first steel rope 4 and connected to the connecting component 61.

[0039] It should be noted that the side of the striking plate 62 adjacent to the first steel rope 4 is an arc-shaped structure, and a rubber layer is provided on the arc-shaped surface. When the rotating shaft 54 rotates, with the cooperation of the connecting component 61, it can drive the striking plate 62 to repeatedly strike the first steel rope 4, so that the first steel rope 4 vibrates.

[0040] Furthermore, if Figure 3 As shown, the connecting assembly 61 includes a turntable 611, a sliding rod 612 and a connecting rod 613, wherein the turntable 611 is arranged at the end of the rotating shaft 54; one end of the connecting rod 613 is hinged to the side wall of the connecting plate 7, and the other end of the connecting rod 613 is fixedly connected to the striking plate 62, and a sliding groove 6130 is provided through the connecting rod 613; the sliding rod 612 is eccentrically arranged on the turntable 611 and is slidably connected to the sliding groove 6130.

[0041] It should be noted that the connecting rod 613 is an L-shaped plate, one end of the connecting rod 613 can be rotatably set on the connecting plate 7, the turntable 611 is coaxially arranged with the rotating shaft 54, the sliding rod 612 does not coincide with the center of the turntable 611, and the sliding rod 612 can slide freely in the sliding groove 6130.

[0042] Specifically, when the rotating shaft 54 rotates, it drives the two turntables 611 to rotate synchronously, and the turntable 611 drives the sliding rod 612 to rotate around its central axis, thereby driving the connecting rod 613 to swing back and forth around its hinge axis, and driving the striking plate 62 to swing back and forth, realizing the striking action on the first steel rope 4.

[0043] In one embodiment of the present application, Figure 4 As shown, the lifting mechanism 3 includes a winding assembly 31, two fixed pulleys 32 and two second steel ropes 33, wherein the winding assembly 31 is installed below the hanging plate 2; the two fixed pulleys 32 are symmetrically arranged on both sides of the winding assembly 31, and the fixed pulleys 32 are connected to the hanging plate 2; one end of the second steel rope 33 is connected to the connecting plate 7, and the other end of the second steel rope 33 passes around the fixed pulley 32 and is connected to the winding assembly 31.

[0044] It should be noted that the two second steel ropes 33 are respectively provided on both sides of the lifting mechanism 3 , and the two second steel ropes 33 are provided on the connecting plate 7 , which improves the stability of the connecting plate 7 .

[0045] Furthermore, the fixed pulley 32 can change the direction of force application, and the winding assembly 31 adjusts the height of the guardrail by retracting and releasing the second steel rope 33. Moreover, one winding assembly 31 can be used to adjust two second steel ropes 33 at the same time, which is convenient to operate and saves the investment cost of the equipment.

[0046] In one embodiment of the present application, Figure 4 As shown, the winding assembly 31 includes two brackets 311, a reel 312 and two baffles 313, wherein the two brackets 311 are respectively arranged on the two side walls of the hanging plate 2; the two baffles 313 are respectively arranged on the corresponding brackets 311; the reel 312 is rotatably arranged between the two baffles 313, and the other end of the second steel rope 33 is fixedly arranged on the reel 312.

[0047] It should be noted that a partition 9 is provided in the center of the reel 312, which divides the reel 312 into two sections. A second steel rope 33 is wound around each of the two sections of the reel 312 to prevent the two second steel ropes 33 from squeezing or entangled with each other during winding, thereby avoiding interference during the winding and unwinding process.

[0048] Furthermore, one end of the reel 312 is connected to an external winding motor, and the reel 312 can be controlled to rotate by the winding motor. The reel motor can be controlled by a controller (not shown in the figure) for easy operation.

[0049] Specifically, the relevant personnel hang the hooks on the first steel ropes 4 on the mounting holes of the guardrail panels, and two first steel ropes 4 are hung on each guardrail panel to keep the guardrail panels horizontal. Then, the multiple guardrail panels are lifted by the lifting mechanism 3 and moved to the top of the zinc pot by the linear motion mechanism 1. The lifting mechanism 3 is used again to control the guardrail panels to move downward. At the same time, the two lifting mechanisms 3 (one lifting mechanism 3 is activated and the other lifting mechanism 3 is deactivated) are used to adjust the inclination angle of the guardrail panels so that the guardrail panels can be immersed in the zinc bath at an angle to ensure the uniformity of the coating. After the guardrail panels are completely immersed in the zinc bath, the lifting mechanisms 3 are used to adjust the guardrail panels to keep them horizontal.

[0050] After hot-dip galvanizing is completed, relevant personnel use the lifting mechanism 3 to slowly remove the guardrail plate from the zinc liquid at an angle of 15° to 45°. The tilted removal can shorten the contact time between the plate surface and the zinc ash layer and reduce the adhesion of surface impurities. Under the action of gravity, the zinc liquid flows down naturally, avoiding the accumulation of zinc liquid in the grooves or edges of the plate surface, thereby ensuring the integrity of the coating.

[0051] Furthermore, in the process of removing the guardrail board, the relevant personnel control the driving mechanism 5 to start, so as to drive the rotating shaft 54 to rotate, and then drive the turntable 611 at both ends to rotate. With the cooperation of the slide bar 612 and the slide groove 6130, the connecting rod 613 and the striking plate 62 can swing back and forth and strike the first steel rope 4. The first steel rope 4 vibrates and drives the guardrail board to vibrate. The excess zinc liquid on the guardrail board is quickly shaken off. At the same time, the liquid bridge between adjacent guardrail boards can also be broken, reducing the generation of irregular zinc nodules or exposed substrate scars, and improving the uniformity of the coating and the protective effect.

[0052] In summary, the galvanized feeding device for the guardrail plate of the embodiment of the present application can strike the first steel rope for hoisting the guardrail plate during the process of lifting the guardrail plate. The vibration is transmitted to the guardrail plate, effectively shaking off excess zinc liquid on the surface and preventing adhesion between the plates, thereby reducing the generation of irregular zinc nodules or exposed substrate scars, and improving the uniformity of the coating and the protective effect.
