Description

Technical Field

[0001] This utility model relates to the field of steel plate transfer technology, specifically a steel plate transverse transfer device for steel plate transfer. Background Technology

[0002] In automated steel plate transport systems, the trolley of the transverse transfer device needs to reciprocate along the track at high frequency. In existing technologies, the guide wheel assembly of the trolley generally adopts a rigid fixed structure: the guide rollers are directly locked to the side wall of the trolley body through brackets, and their wheel surfaces always maintain rigid contact with the side wall of the track.

[0003] When the track becomes uneven due to installation errors or long-term load, the rigid guide wheels cannot absorb the impact energy, resulting in a violent collision between the rollers and the track. This impact force is directly transmitted to the moving trolley, exacerbating the trolley's vibration and causing the steel plate on the support platform to slide horizontally or jump vertically, severely affecting the positioning accuracy of subsequent workstations. To address this, we propose a steel plate transverse transfer device for steel plate transport. Summary of the Invention

[0004] The purpose of this utility model is to provide a steel plate transverse movement device for steel plate transmission, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel plate transverse transfer device for steel plate transmission, comprising: a frame, a traveling track set on the frame, and a mobile trolley movable along the traveling track, wherein the mobile trolley is provided with a support platform for carrying steel plates; guide wheel assemblies are symmetrically installed on both sides of the mobile trolley; the guide wheel assembly comprises: a fixed seat, fixedly set at the bottom of the side of the mobile trolley; a movable bracket, connected to the bottom of the fixed seat by a vertically set elastic element; and guide rollers, rotatably installed at the bottom of the movable bracket by a wheel axle, wherein the outer peripheral surface of the guide rollers rolls in contact with the side wall of the traveling track.

[0006] Preferably, the elastic element is a compression spring, with its upper and lower ends fixedly connected to the fixed base and the movable bracket, respectively.

[0007] Preferably, the outer periphery of the guide roller is covered with a polyurethane wear-resistant layer.

[0008] Preferably, a telescopic cylinder is provided between the movable support and the fixed base, with the bottom end of the telescopic cylinder fixed to the movable support and the top end fixed to the fixed base.

[0009] Preferably, the telescopic cylinder and the elastic element are arranged coaxially.

[0010] Preferably, the bottom of the telescopic cylinder is provided with a through hole that penetrates the movable support. The inner diameter of the through hole is smaller than the inner diameter of the telescopic cylinder, providing a damping and buffering effect.

[0011] Preferably, support plates are fixed on both sides of the support platform, and two adjustable anti-deviation baffles are provided between the two support plates.

[0012] Preferably, a limiting frame is fixedly provided on the side of the anti-deviation baffle near the support plate, the limiting frame passes through the support plate and is slidably connected to the support plate; an adjusting screw is rotatably provided on the side of the anti-deviation baffle near the support plate, the end of the adjusting screw away from the anti-deviation baffle passes through the support plate and is threadedly connected to the support plate; a handle is fixedly provided on the end of the adjusting screw away from the anti-deviation baffle.

[0013] Compared with traditional technologies, the beneficial effects of this utility model are:

[0014] This device uses guide roller assemblies with elastic elements on both sides of the mobile trolley. Vertically installed elastic elements connect the fixed base and the movable support, giving the guide rollers vertical buffering capabilities. When the traveling track becomes uneven due to installation errors or deformation, the elastic elements can compress or rebound immediately, absorbing the impact energy generated by the collision between the rollers and the track sidewalls, reducing the vibration amplitude transmitted to the mobile trolley. This improves the stability of the trolley's operation, prevents displacement caused by horizontal slippage or vertical jump of the steel plate on the support platform, ensures the steel plate is accurately delivered to subsequent workstations, and enhances the positioning reliability of the overall transmission system.

[0015] The elastic buffer structure of the guide roller assembly not only mitigates instantaneous impacts but also avoids stress concentration caused by rigid contact by continuously and adaptively adjusting the contact pressure between the guide roller and the track. Combined with the polyurethane wear-resistant layer covering the guide roller surface, it reduces frictional loss and operating noise. Meanwhile, the coaxial arrangement of the telescopic cylinder and the elastic element, along with the damping effect of the through-hole design, further suppresses the swaying of the movable support, ensuring a stable and controllable guiding process.

[0016] To address the risk of steel plate shifting during transportation, adjustable anti-deviation baffles are added to both sides of the support platform. By rotating the adjusting screw, the limiting frame slides on the support plate, allowing for flexible adjustment of the distance between the two baffles to accommodate steel plates of different sizes. Combined with the shock absorption effect of the aforementioned elastic guide wheel assembly, the double baffles form a stable limiting channel, continuously constraining the position of the steel plate during operation and preventing slippage caused by trolley vibration or inertia.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figures 1-4 The diagram illustrates a steel plate transverse transport device, comprising: a frame 1, a traveling track 2 mounted on the frame 1, and a movable trolley 3 that can move along the traveling track 2. The movable trolley 3 is equipped with a support platform 4 for carrying the steel plate. Guide wheel assemblies are symmetrically mounted on both sides of the movable trolley 3. Each guide wheel assembly includes: a fixed seat 5, fixedly mounted on the bottom side of the movable trolley 3; a movable support 6, connected to the fixed seat 5 below it via a vertically mounted elastic element 7; and guide rollers 8, rotatably mounted on the bottom of the movable support 6 via axles, with the outer circumference of the guide rollers making rolling contact with the side wall of the traveling track 2. When the side wall of the track becomes uneven, the rollers are compressed, pushing the movable support 6 upwards. The elastic element 7 instantly absorbs kinetic energy, preventing a hard collision. After the track returns to a flat state, the elastic element 7 releases potential energy, ensuring that the rollers continue to conform to the track. This dynamic adjustment system maintains guiding accuracy while isolating the impact caused by track unevenness from the vehicle body.

[0024] The following describes some embodiments of this application in detail with reference to the accompanying drawings:

[0025] Please see Figures 1-4 By installing guide wheel assemblies with elastic elements 7 on both sides of the mobile trolley 3, and using the vertically installed elastic elements 7 to connect the fixed base 5 and the movable support 6, the guide rollers 8 have vertical buffering capabilities. When the traveling track 2 becomes uneven due to installation errors or deformation, the elastic elements 7 can compress or rebound immediately, absorbing the impact energy generated by the collision between the rollers and the track sidewalls, reducing the vibration amplitude transmitted to the mobile trolley 3. This improves the stability of the trolley's operation, prevents the steel plate on the support platform 4 from shifting due to severe vibration, ensures the steel plate can be accurately delivered to the subsequent workstation, and improves the positioning reliability of the overall transmission system.

[0026] Among them, the elastic element 7 is a compression spring, with its upper and lower ends fixedly connected to the fixed base 5 and the movable bracket 6, respectively. The linear stiffness characteristics of the spring provide a predictable buffer curve: the spring is slightly compressed when there is a small fluctuation in the track, so as to achieve smooth following; when encountering a sudden deformation, the spring contracts significantly to concentrate and dissipate the impact energy. The symmetrically distributed spring group ensures that the pressure on the rollers on both sides is balanced, preventing the trolley from deviating. At the same time, the replaceable design of the springs makes it easy to adjust the stiffness parameters according to the load.

[0027] In addition, the outer periphery of the guide roller 8 is covered with a polyurethane wear-resistant layer 9. The high elastic modulus of polyurethane reduces the transmission of noise and vibration when the roller comes into contact with the metal of the track; its excellent wear resistance reduces dimensional deformation caused by frequent friction and maintains the stability of the guide clearance. This design is particularly suitable for dusty industrial environments, and the self-cleaning properties of polyurethane can reduce debris adhesion and prevent scratches on the track working surface.

[0028] In this technical solution, a telescopic cylinder 10 is provided between the movable support 6 and the fixed base 5. The bottom end of the telescopic cylinder 10 is fixed to the movable support 6, and the top end is fixed to the fixed base 5. The telescopic cylinder 10 and the elastic element 7 are coaxially arranged, forming a dual-function structure: firstly, the cylinder body isolates external dust from entering the spring gap, preventing jamming; secondly, the cylinder wall limits the horizontal swing amplitude of the movable support 6, avoiding the spring from bending and failing due to lateral force. The design of the top end of the cylinder body being fixed to the fixed base 5 and the bottom end being fixed to the movable support 6 ensures that the telescopic movement trajectory is completely coincident with the spring axis, eliminating the risk of uneven wear.

[0029] In addition, the bottom of the telescopic cylinder 10 is provided with a through hole 11 that penetrates the movable support 6. The inner diameter of the through hole 11 is smaller than the inner diameter of the telescopic cylinder 10, providing a damping buffering effect. When the movable support 6 moves upward rapidly, the air inside the cylinder is compressed and discharged at high speed through the narrow hole, generating fluid resistance. When the support returns, external air is slowly injected through the narrow hole, forming negative pressure damping. This physical damping effect is coupled with the elastic buffering of the spring, significantly suppressing high-frequency vibrations, and is especially suitable for inertial impacts during the start-stop phase of the vehicle.

[0030] The working principle of this device is as follows:

[0031] As the mobile trolley 3 travels along the track 2, the guide rollers 8 symmetrically installed on both sides of the trolley make rolling contact with the track sidewalls. The polyurethane wear-resistant layer 9 covering the outer circumference of the rollers reduces frictional resistance and suppresses metal-to-metal contact noise.

[0032] When the track is locally uneven, the track sidewall applies abnormal pressure to the guide roller 8, pushing the movable bracket 6 upward and compressing the vertically installed spring; the spring deforms and absorbs the impact kinetic energy, avoiding rigid collision. After the impact disappears, the spring releases potential energy to push the movable bracket 6 downward, causing the roller to re-fit against the track wall and maintain a constant guide clearance; in addition, the telescopic cylinder 10, coaxially sleeved on the outside of the spring, restricts the horizontal swaying of the movable bracket 6 and ensures accurate vertical buffer trajectory.

[0033] When the movable support 6 moves rapidly, the air inside the telescopic cylinder 10 is discharged or drawn in at high speed through the narrow hole at the bottom, generating fluid damping force, which further attenuates high-frequency vibration. Example

[0034] This embodiment is an optimization of the structure in Embodiment 1. Specifically, as follows: Figure 2 As shown, support plates 12 are fixedly provided on both sides of the support platform 4. Two adjustable anti-deviation baffles 13 are provided between the two support plates 12. A limiting frame 14 is fixedly provided on the side of the anti-deviation baffle 13 near the support plate 12. The limiting frame 14 passes through the support plate 12 and is slidably connected to the support plate 12. An adjusting screw 15 is rotatably provided on the side of the anti-deviation baffle 13 near the support plate 12. The end of the adjusting screw 15 away from the anti-deviation baffle 13 passes through the support plate 12 and is threadedly connected to the support plate 12. A handle 16 is fixedly provided on the end of the adjusting screw 15 away from the anti-deviation baffle 13.

[0035] The working principle of the steel plate anti-deflection mechanism is as follows:

[0036] Rotating the handle 16 according to the width of the steel plate drives the adjusting screw 15 to rotate. The screw engages with the thread of the support plate 12, causing the anti-deviation baffle 13 to slide along the limiting frame 14, simultaneously adjusting the distance between the two baffles to form a limiting channel adapted to the width of the steel plate;

[0037] After the steel plate is placed on the support platform 4, its two sides are physically constrained by the anti-deviation baffles 13. When the trolley starts or stops or is affected by residual vibration, the baffles bear the lateral thrust through the sliding connection between the limit frame 14 and the support plate 12, preventing the steel plate from sliding horizontally. Combined with the shock absorption effect of the guide wheel assembly, the stability of the support platform 4 is improved, reducing the inertial deviation force of the steel plate.
