Description

Technical Field

[0001] This utility model relates to the field of palletizing technology, and in particular to a palletizing device for stainless steel corrugated beam guardrail panels. Background Technology

[0002] As is widely known, corrugated beam guardrails are an important component of highway safety facilities and are crucial for ensuring driving safety. Corrugated beam guardrails not only effectively absorb the energy of vehicle collisions and reduce accident damage, but also serve as a visual warning and guidance system, raising drivers' safety awareness.

[0003] Corrugated beam guardrails can be divided into two types according to their waveform: double-wave and triple-wave. Among them, triple-wave guardrails are the most common, with higher specifications and stronger safety protection capabilities, and are suitable for high-risk road sections such as highways and bridges.

[0004] Corrugated beam guardrails typically use national standard Q235 low-carbon steel as the base material. This material has good toughness and weldability, making it easy to process and install. During the manufacturing process of the guardrail panels, the steel plates undergo stamping, cutting, and cold bending to form a corrugated structure. To improve the corrosion resistance and durability of the guardrail panels, the surface is usually treated with powder coating or hot-dip galvanizing.

[0005] See Figure 8 As shown, to avoid the environmental pollution and resource and energy consumption problems caused by powder coating or hot-dip galvanizing processes, stainless steel can be selected as the preferred material for corrugated beam guardrails. Existing stainless steel corrugated beam guardrails are obtained by uncoiling, leveling, punching, cutting and forming in sequence to obtain guardrails of the designed specifications and dimensions. Two waist-shaped connecting screw holes are provided at both ends of the guardrails. The size of the waist-shaped connecting screw holes is 24mm×50mm. The two ends of the three-wave guardrails are also provided with multiple splicing screw holes.

[0006] However, existing stainless steel corrugated beam guardrails are prone to falling off and inaccurate positioning during the stacking and handling process.

[0007] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a stainless steel corrugated beam guardrail stacking device. Utility Model Content

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] See Figures 1 to 7 As shown; This embodiment discloses a stainless steel corrugated beam guardrail stacking device. The stacking device is arranged across the stainless steel corrugated beam guardrail conveying device 20 and the stainless steel corrugated beam guardrail stacking support frame 30. The stacking device can move along the slide rail 40 located above the conveying device 20 and the support frame 30 to stack the stainless steel corrugated beam guardrail 10 on the conveying device onto the support frame 11. The palletizing device includes a frame 2; a main assembly 1 connected to the frame 2 and capable of moving the frame 2 vertically to adjust the height of the frame 2, the main assembly 1 being capable of moving along a slide rail 40; A chute structure 3 is provided along the length of the frame 2, and a gripping mechanism 4 is provided at both ends of the chute structure 3. The gripping mechanism 4 at both ends can move along the chute 301 of the chute structure 3 to adjust the relative distance. The gripping mechanism 4 has a hook that can extend into the waist-shaped connecting screw hole 11 corresponding to the stainless steel corrugated beam guardrail plate 10. The gripping mechanism 4 at both ends of the device grips the stainless steel corrugated beam guardrail plate 10 through the cooperation of the hook 406 with the waist-shaped connecting screw hole 11.

[0025] Specifically, this embodiment discloses a stacking device suitable for the transfer and stacking of stainless steel corrugated beam guardrail panels 10. Its main design incorporates a gripping mechanism 4 with oblong connecting screw holes 11 that can adapt to different specifications of stainless steel corrugated beam guardrail panels 10. Firstly, this embodiment sets up the stacking device according to the workshop layout and the slide rail 40 located between the conveying device 20 of the stainless steel corrugated beam guardrail panels 10 and the support frame 30 for stacking the stainless steel corrugated beam guardrail panels 10. The stacking device of this embodiment can move along the slide rail 40 via an external drive structure to transport the stainless steel corrugated beam guardrail panels 10 from the conveying device to the support frame 30 for stacking.

[0026] The palletizing device of this embodiment includes a main assembly 1, a frame 2, and a slide structure 3 below it. At the same time, a gripping mechanism 4 of this embodiment is provided at both ends of the slide structure 3. The main assembly 1 of this embodiment can drive the frame 2, the slide structure 3, and the gripping mechanism 4 to move vertically through the lifting mechanism 102. When the gripping mechanism 4 grips the stainless steel corrugated beam guardrail 10 through the hook 406, the lifting mechanism 102 is raised, and the device as a whole is driven to move along the slide rail 40 through the external driving device to stack the gripped stainless steel corrugated beam guardrail 10 onto the support frame 30, and then the next operation is performed.

[0027] Preferably, the main assembly 1 of the device in this embodiment includes: a support plate 101, with slides 103 at both ends of the support plate 101 that slide in cooperation with the slide rail 40; a lifting mechanism 102 installed on the support plate 101, with the driving end of the lifting mechanism 102 extending downward and connecting to the frame 2 below to drive the frame 2 to lift; a guide hole is provided on the edge of the support plate 101, and a guide sleeve 105 is provided at the guide hole, and the support plate 101 is connected to the frame 2 below through a guide post 104 passing through the guide sleeve 105.

[0028] First, see Figures 1 to 2 As shown, this embodiment further defines the structure of the main assembly 1 of the device, which is based on the support plate 101. The device moves along the slide rail 40 through the sliding engagement of the slide tables 103 at both ends of the support plate 101 with the slide rail 40. At the same time, in order to realize the lifting and lowering of the lower frame 2 and other mechanisms, a lifting mechanism 102 is provided on the support plate 101 in this embodiment. Preferably, the lifting mechanism 102 in this embodiment can be a lifting cylinder or a hydraulic cylinder, and the output end of the lifting cylinder or hydraulic cylinder passes through the support plate 101 and extends downward to connect with the frame 2, thereby driving the frame 2 to move in the vertical direction.

[0029] Secondly, as a preferred embodiment, in order to ensure the stability of vertical height adjustment, four sets of guide columns 104 are provided between the support plate 101 and the frame 2 in this embodiment. The specific structure is as above, and the guide columns 104 cooperate with the corresponding guide sleeves 105.

[0030] See Figures 3 to 6 As shown, preferably, in this embodiment, the gripping mechanism 4 and the slide groove 301 of the slide groove structure 3 are slidably engaged by the sliding seat 411, and the sliding seat 411 and the slide groove 301 are slidably engaged by the sliding block 412 at its upper end. The sliding block 412 is connected to the screw 414, and the upper end of the screw 414 is equipped with a locking nut 415. The sliding seat 411 locks the position of the gripping mechanism 4 by the locking nut 415. A connecting beam 413 is connected between the sliding seats 411 on both sides.

[0031] First, this embodiment further defines the sliding fit structure between the gripping mechanism 4 and the slide structure 3. The sliding fit is mainly achieved through the sliding seat 411. In order to fix the position after adjusting the position of the gripping mechanisms 4 at both ends, the sliding seat 411 in this embodiment is provided with a screw 414 and a locking nut 415. After locking the locking nut 415, the positioning and fixation with the slide structure 3 can be achieved, thereby completing the positioning of the gripping mechanism 4.

[0032] Secondly, see Figures 4 to 6 As shown, the gripping mechanism 4 in this embodiment includes: a gripping mechanism recovery cylinder 401 fixedly connected to the lower part of the sliding seat 411, and a bracket 408 connected between the mounting parts at the upper ends of the two gripping mechanism recovery cylinders 401; a gripping mechanism slide 402 slidably connected to the lower end of the gripping mechanism recovery cylinder 401, and a crossbeam connected between the two gripping mechanism slides 402; a spline shaft 407 connected between the two gripping mechanism slides 402, and a spline sleeve 405 installed on the spline shaft 407, and a hook 406 connected to the spline shaft 407 through the spline sleeve 405; a gripping mechanism drive cylinder 409 installed below the bracket 408, and the gripping mechanism drive cylinder 409 connected to the crossbeam through a connector 410 to drive the gripping mechanism slide 402 to move along the axial direction of the gripping mechanism recovery cylinder 401 to adjust the relative position of the hook 406 and the waist-shaped connecting screw hole 11 of the stainless steel corrugated beam guardrail plate 10.

[0033] This embodiment further defines the structure of the gripping mechanism 4, which has gripping mechanism recovery cylinders 401 at both ends. A gripping mechanism slide 402 is slidably connected below the gripping mechanism recovery cylinders 401, and a spline shaft 407 is connected between the gripping mechanism slides 402. The hook 406 of the gripping mechanism 4 in this embodiment is integrated below the spline shaft 407 by a spline sleeve 405 installed at a designated position on the spline shaft 407. Specifically, the position of the hook 406 can be adjusted and positioned according to the waist-shaped connecting screw hole 11 of the stainless steel corrugated beam guardrail 10 based on the cooperation of the spline shaft 407 and the spline sleeve 405, so as to adapt to the hoisting requirements of stainless steel corrugated beam guardrail 10 of different specifications.

[0034] Furthermore, in this embodiment, the engagement between the hook 406 and the waist-shaped connecting screw hole 11 is achieved through the hook 406 abutting against the inner wall of one side of the waist-shaped connecting screw hole 11 and the structure of the hook 406 itself. Therefore, this embodiment is designed with a gripping mechanism drive cylinder 409 that can drive the gripping mechanism slide 402 to move relative to the gripping mechanism recovery cylinder 401. When it is necessary to disengage the hook 406 from the waist-shaped connecting screw hole 11, the cylinder rod of the gripping mechanism drive cylinder 409 extends and drives the connecting member 410 to move synchronously with the crossbeam, thereby driving the gripping mechanism slide 402 to move. At this time, the hook 406 disengages from the gripping position of the waist-shaped connecting screw hole 11, and the hook 406 can then move in and out relative to the waist-shaped connecting screw hole 11. More preferably, in order to achieve the reset of the hook 406 under the simultaneous action of the gripping mechanism drive cylinder 409 and the gripping mechanism reset cylinder 401, the lower part of the gripping mechanism reset cylinder 401 in this embodiment is provided with a sliding groove that slides with the gripping mechanism slide 402, and a compression spring 416 is installed inside the gripping mechanism reset cylinder 401. The compression spring 416 drives the gripping mechanism slide 402 to reset by spring force. The dual action of the compression spring 416 and the gripping mechanism drive cylinder 409 realizes the reset of the gripping mechanism 4 and guides the hook 406 to the mating position of the waist-shaped connecting screw hole 11 for gripping and subsequent stacking operations.

[0035] In order to adjust the position of the two hooks 406 along the axial direction of the spline shaft 407 and to position and lock the adjusted position, in this embodiment, the part of the spline shaft 407 between the two spline sleeves 405 is fitted with an intermediate sleeve 403, and the part of the spline shaft 407 between the spline sleeve 405 and the gripping mechanism slide 402 on the corresponding side is fitted with an edge sleeve 404; the relative distance between the two spline sleeves 405 is controlled by the intermediate sleeve 403 and the edge sleeve 404.

[0036] Preferably, in order to achieve relative position adjustment of the gripping mechanisms 4 at both ends, the frame 2 in this embodiment has a drive component for driving the gripping mechanisms 4 at both ends of the slide structure 3 to move synchronously, and the gripping mechanisms at both ends achieve synchronous and opposite movement through the drive component.

[0037] More specifically, the drive assembly in this embodiment includes a drive motor 501 installed in the middle of the frame 2, a drive gear 502 installed at the output end of the drive motor 501, and a driven gear connected to the drive gear 502. The drive assembly also includes a double helical screw 503 connected to the driven gear and extending along the length of the slide structure 3 to both ends of the gripping mechanism 4, and the threads at both ends of the double helical screw 503 are in opposite directions; a screw nut 504 is provided on the connecting beam 413, the screw nut 504 is threadedly connected to the double helical screw 503, and the end of the double helical screw 503 is rotatably connected to the profile at the end of the slide structure 3 through the end bearing seat 505.

[0038] In addition, during operation, the device is positioned directly above the conveying device 20. To ensure that the stainless steel corrugated beam guardrail 10 is located directly below the gripping mechanism 4, guide side plates can be arranged on both sides of the conveying device 20 and blocking components can be installed at the end positions. The position of the stainless steel corrugated beam guardrail 10 during transportation is positioned by the cooperation of the two, thereby facilitating the gripping operation of the device gripping mechanism 4.

[0039] In actual production, the distance between the two gripping mechanisms 4 is first adjusted by the drive motor 501, and then the locking nut 415 is locked to position the two gripping mechanisms 4. Subsequently, the frame 2 is moved to the corresponding position of the conveying device 20 by the cooperation of the slide table 103 and the slide rail 40, and then the frame 2 is driven to descend by the lifting mechanism 102, ensuring that the hook 406 of the gripping mechanism 4 can enter the waist-shaped connecting screw hole 11 at the corresponding position of the stainless steel corrugated beam guardrail 10. When the hook 406 and the waist-shaped connecting screw hole 11 reach the mating position, the gripping mechanism drives the cylinder 409 to retract, and under the action of the compression spring 416 in the gripping mechanism return cylinder 401, it ensures that the hook 406 abuts against the inner wall of one end of the waist-shaped connecting screw hole 11. At this time, under the action of the four hooks 406 of the two gripping mechanisms 4, the gripping of the stainless steel corrugated beam guardrail 10 is completed. Then, the frame 2 can be raised by the lifting mechanism 102 and transferred to the support frame 30. Finally, the stainless steel corrugated beam guardrail 10 is lowered to complete the stacking. This process can be repeated.

[0040] In the above technical solution, the stainless steel corrugated beam guardrail stacking device provided by this utility model has the following beneficial effects: The device of this utility model can effectively grasp the stainless steel corrugated beam guardrail 10 without it falling off during the grasping process. At the same time, since the hook 406 acts in the corresponding waist-shaped connecting screw hole 11, it is equivalent to pre-positioning the stainless steel corrugated beam guardrail 10 on the palletizer. When the palletizer places the stainless steel corrugated beam guardrail 10 on the support frame 30, the stainless steel corrugated beam guardrail 10 can be neatly and accurately stacked on the support frame 30.

[0041] The device of this utility model can solve the problems of easy detachment and inaccurate stacking positioning of existing stainless steel corrugated beam guardrail 10 during the stacking process, ensuring that the stainless steel corrugated beam guardrail 10 can be stacked efficiently and accurately, while effectively preventing detachment.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
