Description

Technical Field

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

[0002] Guardrails are key facilities for highway collision prevention and play an important protective role when cars lose control and run off the road. The transportation efficiency during their production and processing directly affects the overall production capacity. At present, the industry generally adopts guardrail conveying devices based on conveyor belts. This type of device mainly realizes the displacement of guardrails through the conveyor belt on the workbench in conjunction with fixed tracks or chain drives.

[0003] However, the fixed track structure of the existing technology makes the device less adaptable to the specifications of the guardrail boards. When conveying guardrail boards of different widths or thicknesses, the track width needs to be adjusted manually. This process not only consumes a lot of time and reduces production efficiency, but also manual operation is prone to errors, which can easily cause the guardrail boards to deflect, get stuck, or even collide and be damaged during transportation. In addition, iron filings generated during the processing of the guardrail boards are easily accumulated in the gap between the conveyor belt and the track, which not only increases equipment wear, but may also cause safety hazards such as conveyor belt jamming. Summary of the Invention

[0004] The present application aims to solve one of the technical problems in the related art at least to a certain extent.

[0005] To this end, one purpose of this application is to provide a conveying device for guardrail board production, which can achieve efficient and stable conveying of guardrail boards of different specifications, and integrate iron chip collection design to effectively reduce equipment loss.

[0006] To achieve the above-mentioned purpose, the first aspect embodiment of the present application proposes a conveying device for guardrail board production, comprising a conveying platform, an adjusting device and two limiting devices, wherein the two limiting devices are respectively arranged at the top of the conveying platform; the adjusting device is arranged in the conveying platform, and the adjusting device is respectively connected to the two limiting devices, and the adjusting device is used to drive the two limiting devices to move in opposite directions; the adjusting device includes a first driving component arranged in the conveying platform, and its shaft is threadedly connected to the adjusting component to drive the two limiting devices to move in opposite directions; the limiting device includes a fixing component fixed to the top of the adjusting component, which is provided with a limiting component for assisting the movement of the guardrail board, and a second driving component for adjusting the limiting component to adapt to guardrail boards of different specifications.

[0007] The conveying device for guardrail board production in the embodiment of the present application can achieve efficient and stable conveying of guardrail boards of different specifications, and has an integrated iron chip collection design to effectively reduce equipment loss.

[0008] In addition, the conveying device for guardrail production proposed in the present application may also have the following additional technical features:

[0009] In one embodiment of the present application, a conveyor belt and belt rollers for assisting its rotation are provided in the conveyor platform.

[0010] In one embodiment of the present application, a placement slot for placing the first drive component is provided in the conveying platform, and there are two placement slots. A slag discharge slot is provided in the conveying platform for collecting iron filings dropped on the conveyor belt, and the slag discharge slot is located between the two placement slots.

[0011] In one embodiment of the present application, support legs for supporting the conveyor platform are fixedly installed at the bottom end of the conveyor platform, and there are four support legs, which are distributed in a rectangular array at the bottom end of the conveyor platform.

[0012] In one embodiment of the present application, the first drive assembly includes a bidirectional screw rod arranged in the placement slot on the right side for driving the adjustment assembly to move, the front end of the bidirectional screw rod is fixedly installed with a first motor for driving the bidirectional screw rod to rotate, and the placement slot on the left side is provided with a guide rod for assisting the adjustment assembly to move.

[0013] In one embodiment of the present application, the adjustment assembly includes a first threaded sleeve threadedly connected to the bidirectional screw rod, and the rod body of the guide rod is sleeved with a first fixed sleeve for supporting the fixed assembly.

[0014] In one embodiment of the present application, the fixing assembly includes a support frame fixedly installed on the top of the first fixing sleeve, and two long slots are defined in the support frame.

[0015] In one embodiment of the present application, the second driving assembly includes a threaded rod arranged in the long slot on the left side for driving the limiting assembly to move up and down, a second motor for driving the threaded rod to rotate is fixedly installed on the top end of the threaded rod, and a sliding rod located in the long slot on the right side for assisting the limiting assembly to move up and down.

[0016] In one embodiment of the present application, the limiting assembly includes a fixed frame arranged in a support frame, a second threaded sleeve for threaded connection to a threaded rod is fixedly installed on the left end of the fixed frame, a second fixed sleeve for sleeved on a sliding rod is fixedly installed on the right end of the fixed frame, and rollers for rotation are movably connected in the fixed frame, and there are several rollers.

[0017] Compared with the prior art, the present invention has the following advantages:

[0019] 2. Position the guardrail conveying path to improve conveying stability. The roller in the limiting device can be accurately aligned with the middle of the guardrail through the adjustment of the second drive component. Combined with the guide structure of the flexible roller and the slide bar, a dynamic clamping effect is formed to effectively prevent the guardrail from deflecting, getting stuck or being damaged by collision during transportation.

[0020] 3. The integrated iron chip collection design reduces the risk of equipment loss. The slag discharge chute in the conveyor platform is located between the two placement troughs. Its special cross-sectional design can guide the iron chips that fall from the conveyor belt to automatically gather and discharge, avoiding the accumulation of iron chips in the equipment gap, thereby reducing equipment wear and eliminating safety hazards such as conveyor belt jamming.

DETAILED DESCRIPTION

[0031] The embodiments of the present application are described in detail below. 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.

[0032] The following describes the conveying device for guardrail plate production according to an embodiment of the present application with reference to the accompanying drawings.

[0033] like Figure 1-Figure 7 As shown, the conveying device for guardrail plate production according to an embodiment of the present application may include a conveying platform 100 , an adjusting device 200 and two limiting devices 300 .

[0034] Among them, two limiting devices 300 are respectively arranged at the top of the conveying platform 100, the adjusting device 200 is arranged in the conveying platform 100, and the adjusting device 200 is respectively connected to the two limiting devices 300, and the adjusting device 200 is used to drive the two limiting devices 300 to move in opposite directions. The adjusting device 200 includes a first driving component 210 arranged in the conveying platform 100, and its shaft is threadedly connected to the adjusting component 220 to drive the two limiting devices 300 to move in opposite directions. The limiting device 300 includes a fixing component 310 fixed to the top of the adjusting component 220, which is provided with a limiting component 330 for assisting the movement of the guardrail plate, and a second driving component 320 for adjusting the limiting component 330 to adapt to guardrail plates of different specifications.

[0035] In one embodiment of the present application, Figure 2 and Figure 3 As shown, a conveyor belt 101 is provided in the conveyor platform 100 for driving the guardrail plate for transportation, and the conveyor belt 101 has through holes, so that the iron slag after the guardrail plate is processed can fall into the conveyor platform 100 along the through holes on the conveyor belt 101.

[0036] Specifically, a belt roller 102 is provided in the conveyor belt 101 for assisting the conveyor belt 101 to rotate, and there are two belt rollers 102. The two belt rollers 102 are symmetrically distributed in the conveyor platform 100. At the same time, one of the belt rollers 102 is connected to an external motor, so the belt roller 102 can be driven by the motor to rotate, driving the conveyor belt 101 to move, so that the processed guardrail plate can be transported.

[0037] In one embodiment of the present application, a placement slot 104 for placing the first drive component 210 is provided in the conveyor platform 100, and there are two placement slots 104, and the two placement slots 104 are symmetrically distributed in the conveyor platform 100 on the left and right. A slag discharge slot 103 for collecting iron filings dropped from the conveyor belt 101 is provided in the conveyor platform 100, and the slag discharge slot 103 is located between the two placement slots 104, and the cross-section of the slag discharge slot 103 is high on the left and right sides and low in the middle.

[0038] Specifically, the iron slag generated during the processing of the guardrail plate can fall into the conveying platform 100 along the through holes on the conveyor belt 101 and be discharged along the slag discharge chute 103 to collect the iron slag.

[0039] In one embodiment of the present application, support legs 105 for supporting the conveyor platform 100 are fixedly installed at the bottom end of the conveyor platform 100 , and there are four support legs 105 , which are distributed in a rectangular array at the bottom end of the conveyor platform 100 .

[0040] Specifically, the conveying platform 100 can be supported by four supporting legs 105 .

[0041] In one embodiment of the present application, Figure 3 As shown, the first drive component 210 may include a bidirectional screw rod 212 arranged in the placement groove 104 on the right side for driving the adjustment component 220 to move, and the front and rear ends of the bidirectional screw rod 212 can be connected to the groove wall of the placement groove 104 through bearings to facilitate the rotation of the bidirectional screw rod 212, and there are two sections of front-to-back symmetrical threads on the rod body of the bidirectional screw rod 212, and the thread rotation directions of the two sections of threads are opposite, so that the two adjustment components 220 located on the bidirectional screw rod 212 can move in opposite directions; the front end of the bidirectional screw rod 212 is fixedly installed with a first motor 211 for driving the bidirectional screw rod 212 to rotate, and the shaft end of the output shaft of the first motor 211 is connected to the front end of the bidirectional screw rod 212 through a coupling.

[0042] Specifically, the first motor 211 is connected to the central processing unit of the external control system through an electrical interface. The control system integrates an encoder and an adaptive adjustment algorithm: when the guardrail board enters the conveyor platform 100, the encoder collects the edge position data of the guardrail board in real time and converts it into an electrical signal. After being processed by the control system, a pulse control signal is generated to drive the first motor 211 to rotate precisely according to preset parameters; the motor output shaft drives the bidirectional screw 212 to rotate through the coupling, and the two sections of reverse threads on the rod body drive the first threaded sleeves 221 on both sides to move in opposite directions along the axial direction. At the same time, the guide rod 213 in the left side placement groove 104 is fixed by the groove wall fixing structure at the upper and lower ends to provide a linear motion guide for the adjustment component 220, ensuring that the first fixed sleeve 222 maintains parallelism during movement, thereby realizing synchronous and symmetrical adjustment of the limiting devices 300 on both sides.

[0043] In one embodiment of the present application, Figure 4 As shown, the adjustment assembly 220 may include a first threaded sleeve 221 threadedly connected to the bidirectional screw rod 212 , and the rod body of the guide rod 213 is sleeved with a first fixed sleeve 222 for supporting the fixed assembly 310 .

[0044] Specifically, the width of the guardrail board is identified by the encoder, and the control system automatically drives the first motor 211 to rotate the bidirectional screw rod 212, so that the two first threaded sleeves 221 located on the two sections of the thread on the bidirectional screw rod 212 move in opposite directions along the bidirectional screw rod 212, and the two limiting devices 300 can be controlled to adjust accordingly according to the width of the guardrail board.

[0045] It should be noted that the encoder described in this embodiment of the present application can use a high-precision photoelectric encoder as a specification identification element. The specific model can be the E6B2-CWZ6C series, which is fixed to the side baffle at the entrance end of the conveyor platform 100 through an L-shaped mounting bracket. The detection end face is perpendicular to the conveying plane of the conveyor belt 101, and the vertical height from the guardrail conveying path is 50-80mm, ensuring that the scanning beam can completely cover the upper surface of the guardrail. The axis of the encoder is perpendicular to the conveying direction of the guardrail, forming a horizontal scanning detection surface.

[0046] When the guardrail enters the detection area along with the conveyor belt 101, the infrared emitting tube of the encoder continuously emits a parallel light beam. After being reflected by the edge of the guardrail, the light beam is converted into an electrical signal by the receiving tube. The signal processing circuit inside the encoder filters and amplifies the reflected signal. By calculating the product of the time difference Δt when the light beam is blocked and the linear speed v of the conveyor belt (L=v×Δt), the actual width value of the guardrail is accurately obtained. This calculation process is completed by the encoder's built-in 16-bit MCU.

[0047] The encoder establishes a data connection with an external PLC control system (optional Siemens S7-200SMART) via the RS485 communication interface, transmitting guardrail width data in real time. The control system has a built-in width matching algorithm that compares the measured width value with the preset specification database (which can store more than 12 standard specifications) and automatically generates adjustment parameters:

[0048] When the width value L is identified, the control system calculates the rotation angle θ=K×L (K is a proportional coefficient determined by the mechanical transmission ratio) of the bidirectional screw rod 212 .

[0049] At the same time, according to the thickness parameter of the guardrail board (which can be obtained through an additional sensor), the number of rotations N of the second motor 321 is generated to ensure that the working surface of the roller 334 maintains a pressing amount of 5-10mm with the upper surface of the guardrail board.

[0050] In one embodiment of the present application, Figure 4-Figure 7 As shown, the fixing assembly 310 may include a support frame 311 fixedly installed on the top of the first fixing sleeve 222, and the bottom end of the support frame 311 is welded to the top of the first threaded sleeve 221, and two long grooves 312 are opened in the support frame 311, and the two long grooves 312 are symmetrically distributed in the support frame 311 on the left and right.

[0051] The second driving assembly 320 may include a threaded rod 322 arranged in the left long groove 312 for driving the limiting assembly 330 to move up and down, and the upper and lower ends of the threaded rod 322 are connected to the groove wall of the left long groove 312 through bearings to facilitate the rotation of the threaded rod 322; the top of the threaded rod 322 is fixedly installed with a second motor 321 for driving the threaded rod 322 to rotate, and the second motor 321 can be connected to the top of the threaded rod 322 through a coupling. At the same time, the second motor 321 is connected to the external control system, and the identification component in the external control system can identify the width of the guardrail board, so that the second motor 321 can be rotated forward and reversed, so that the threaded rod 322 can rotate synchronously, so that the limiting assembly 330 can be aligned with the middle of the guardrail board; the sliding rod 323 located in the right long groove 312 is used to assist the limiting assembly 330 to move up and down.

[0052] In one embodiment of the present application, Figure 5 As shown, the limiting assembly 330 may include a fixed frame 331 arranged in the support frame 311, the left end of the fixed frame 331 is fixedly installed with a second threaded sleeve 332 for threaded connection with the threaded rod 322, the right end of the fixed frame 331 is fixedly installed with a second fixed sleeve 333 for being mounted on the sliding rod 323, and a roller 334 for rotation is movably connected in the fixed frame 331, and there are several rollers 334, which are distributed in a linear array in the fixed frame 331; and the roller 334 is flexible.

[0053] Specifically, when it is necessary to control the several rollers 334 on the two fixed frames 331 to adjust according to the width of the guardrail board, the second motor 321 can be controlled by identifying the component in the external control system to control the threaded rod 322 to rotate; and the second threaded sleeve 332 on the fixed frame 331 can move up and down along the rod body of the threaded rod 322, and at the same time, the second fixed sleeve 333 on the fixed frame 331 moves up and down along the sliding rod 323, so that the several rollers 334 on the two fixed frames 331 can be controlled to align with the middle of the guardrail board; so as to facilitate the use of the conveyor belt 101 to transport the guardrail board.

[0054] Specifically, the overall workflow and principles of this application are as follows:

[0055] Guardrail board conveying starts: the guardrail board is placed on the conveyor belt 101 of the conveyor platform 100, and the external motor drives the belt roller 102 to rotate, driving the conveyor belt 101 to start conveying the guardrail board.

[0056] Guardrail board specification identification: After the guardrail board enters the conveyor platform 100, the encoder in the external control system identifies the width specification of the guardrail board in real time and transmits the identification signal to the control system.

[0057] Horizontal adjustment of the limiting device: The control system drives the first motor 211 to operate according to the recognition signal of the encoder. The first motor 211 drives the bidirectional screw rod 212 to rotate through the coupling. The two sections of reverse threads on the bidirectional screw rod 212 are used to make the two first threaded sleeves 221 move in opposite directions along the bidirectional screw rod 212, thereby driving the limiting device 300 fixed on the first threaded sleeve 221 to adjust the spacing to adapt to the current width of the guardrail plate. The guide rod 213 in the left side placement slot 104 provides guidance for the adjustment component 220 to ensure that the limiting device 300 moves smoothly.

[0058] Vertical adjustment of the limiting component: The control system controls the operation of the second motor 321 through the identification component. The second motor 321 drives the threaded rod 322 to rotate, so that the second threaded sleeve 332 on the fixed frame 331 moves up and down along the threaded rod 322. At the same time, the second fixed sleeve 333 on the right side of the fixed frame 331 moves along the sliding rod 323, thereby adjusting the vertical position of several rollers 334 in the fixed frame 331, so that the rollers 334 are aligned with the middle of the guardrail plate, thereby assisting the guardrail plate to move stably.

[0059] Iron chip collection and processing: Iron chips generated during the guardrail plate processing fall into the conveyor platform 100 through the through holes on the conveyor belt 101. Since the cross-section of the slag discharge trough 103 is a structure with high left and right sides and low middle, the iron chips automatically gather in the slag discharge trough 103 and are discharged, realizing the collection and processing of iron chips.

[0060] Continuous conveyance of guardrail panels: With the assistance of the limiting device 300 and the roller 334 , the conveyor belt 101 continuously and stably conveys the guardrail panels to the designated position, completing the entire conveying process.

[0061] In summary, the conveying device for guardrail board production in the embodiment of the present application can achieve efficient and stable conveying of guardrail boards of different specifications, and integrates the iron chip collection design to effectively reduce equipment loss.
