Description

Technical Field

[0001] The present invention belongs to the technical field of casting, and in particular relates to an anti-offside device and an anti-offside method for an automated casting production line. Background Art

[0002] There are generally two operating modes for circular casting production lines. One is that a high-power motor pulls the chain panel to run on the track. This design requires a large working space to meet the arc rotation angle. Domestic simple production lines normally use the high-power motor pulling panel design; the other is to add a conveying device as a carrier at the end of the production line to convey the production line trolley for track change processing. This design method is more commonly used in imported production lines, but during operation, the production line's anti-offside protection often fails, resulting in offside rollover, damage to components and serious impact on production.

[0003] Existing production line anti-offside devices feature steam-operated anti-offside sticks, installed in pairs at the top and end of the production line track. These sticks extend and retract to press against the side panels of the track trolley, limiting their position. During operation, the track trolley often moves prematurely to the rotating mechanism due to inertia, triggering a proximity switch and causing the steam-operated anti-offside sticks to press against the side of the track trolley. However, the push cylinder behind the track continues to operate, pushing the track trolley forward. This causes relative movement between the track trolley and the steam-operated anti-offside stick's retractable shaft, bending the shaft and rendering the anti-offside device ineffective.

[0004] like Figure 1 and Figure 2 As shown, the existing circular casting production line includes four corner sections, A, B, C, and D, forming four linear tracks, AB, BC, CD, and DA. Each of these four sections is equipped with a steering mechanism. The existing production line's anti-offside device consists of a set of anti-offside steam rods installed at each end of the linear track. During lateral pushing, when the moving steering devices of angles A, B, C and D are consistent with the lateral tracks, the control system turns on the large pushing cylinders at angles A and C, and synchronously pushes the track trolleys 7 of the two lateral tracks forward. When the AB track and the CD track end trolleys enter the B angle moving turning device and the D angle moving turning device respectively and touch the proximity switch after they are in place, the control system starts the anti-offside gas rods. The anti-offside gas rods are respectively placed in groups of two on both sides of the starting track trolley 7 and the end track trolley 7 of the AB track. Similarly, they are placed in groups of two on both sides of the starting track trolley 7 and the end track trolley 7 of the CD track. The anti-offside gas rods simultaneously press to stabilize all the track trolleys 7 of the AB and CD track on the specified positions. Similarly, for the longitudinal BC and DA tracks, after the AB and CD track trolleys 7 are positioned, the ABCD angles, the moving turning devices work in accordance with the BC and DA longitudinal tracks respectively, and the B angle pushing cylinder and the D angle pushing cylinder work.

[0005] However, when the large cylinder pushes the production line track trolley 7 forward, due to the air pressure or the track and the corner rotating device are not completely horizontal, and the production line track trolleys 7 are independent of each other, due to inertia, the single trolley that enters the mobile corner device enters the mobile corner device for a few seconds first, and touches the proximity switch of the mobile corner device control system. The control system sends a signal to the anti-offside gas rod to work and press the online track trolley 7. At this time, the pushing cylinder is still pushing the track trolley 7, which causes the anti-offside gas rod and the track trolley 7 to move relative to each other, and the anti-offside gas rod push rod is bent, thereby losing the anti-offside effect, and finally causing the control system to fail and the trolley to overturn. Summary of the Invention

[0006] The purpose of the present invention is to provide an anti-offside device for an automated casting production line, an automated casting production line, and an anti-offside method for an automated casting production line, which can ensure that the anti-offside device is always in an effective state and avoid the phenomenon of the rail trolley overturning and production suspension of the casting production line due to failure of the anti-offside system.

[0007] In order to achieve the above object, the solution of the present invention is:

[0008] An anti-offside device for an automated casting production line comprises a limit plate, one end of which is provided with a rotating shaft;

[0009] It also includes a driving device for driving the limit plate to rotate around the rotation axis, and the driving device can drive the limit plate to rotate around the rotation axis so that one side of the limit plate is in close contact with the side of the rail trolley.

[0010] The portion of the limit plate that contacts the rail trolley is provided with a friction plate.

[0011] A positioning plate along the length direction of the adjacent track is further installed on the side of the above-mentioned limiting plate away from the adjacent track, and a return spring is connected between the positioning plate and the limiting plate;

[0012] When the return spring is in a natural state, the limit plate does not contact the rail trolley; when one side of the limit plate is in contact with the side of the rail trolley, the return spring is in an extended state.

[0013] One end of the return spring is connected to the end of the limiting plate away from the rotating shaft.

[0014] When the return spring is in a natural state, the limiting plate fits the positioning plate.

[0015] The driving device includes a driving cylinder, which is arranged on the side of the limit plate away from the rail trolley, and the movement direction of the output shaft of the driving cylinder is perpendicular to the moving direction of the rail trolley.

[0016] Along the forward direction of the rail trolley, one end of the limiting plate where the rotating shaft is provided is located in front of the other end.

[0017] An automated casting production line comprises the automated casting production line anti-offside device as described above.

[0018] An anti-offside method for an automated casting production line comprises the following steps:

[0019] Step 1: Install the above-mentioned anti-offside device of the automated casting production line at both ends of the production line track;

[0020] Step 2: The track trolley moves to the moving corner device and touches the proximity switch, which then sends a control command to the anti-offside device of the automated casting production line on both sides of the track;

[0021] Step 3: The driving device in the anti-offside device of the automated casting production line drives the limit plate to rotate around the rotation axis until one side of the limit plate is in close contact with the side of the rail trolley, thereby completing the limitation of the rail trolley.

[0022] After adopting the above solution, the present invention has the following improvements compared with the prior art:

[0023] (1) The anti-offside device provided by the present invention is to rotate the limit plate so that the side surfaces of the limit plates on both sides of the rail trolley are respectively pressed against the side surfaces of the rail trolley, and the rail trolley is limited by the pressure from both sides. At this time, even if there is relative movement between the rail trolley and the limit plate, the output end of the drive device and the limit plate are still in a relatively static state, which will not affect the drive device, so that the anti-offside device is always in an effective state, avoiding the phenomenon of the rail trolley overturning and stopping production due to the failure of the anti-offside system in the casting production line;

[0024] (2) The present invention provides a friction plate on the portion of the limit plate that contacts the rail trolley, thereby increasing the friction between the limit plate and the rail trolley and improving the limiting effect of the limit plate on the rail trolley;

[0025] (3) The present invention further installs a positioning plate on the side of the limit plate away from the adjacent track, and a return spring is provided between the limit plate and the positioning plate. The return spring can apply a pulling force to the limit plate. When the driving device does not apply an external force to the limit plate, the return spring can ensure that the limit plate does not contact the side of the track trolley.

[0038] The technical solutions and beneficial effects of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] The following describes embodiments of the present invention in detail, examples of which 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 invention, and are not to be construed as limiting the present invention.

[0040] like Figure 3 As shown, the present invention provides an anti-offside device for an automated casting production line, comprising a limit plate 1, one end of which is provided with a rotating shaft 2, which is located on one side of an adjacent track, and the limit plate 1 can rotate around the rotating shaft 2. A driving cylinder 6 is installed on the side of the limit plate 1 away from the track, and the movement direction of the output shaft of the driving cylinder 6 is perpendicular to the length direction of the adjacent track. When the driving cylinder 6 is working, the output shaft extends toward the limit plate 1 and presses against the side of the limit plate 1. As the output shaft of the driving cylinder 6 continues to extend, it can drive the limit plate 1 to rotate around the rotating shaft 2, and gradually reduce the distance between the side of the limit plate 1 close to the track and the track, until the side of the limit plate 1 contacts the side of the track trolley 7 located on the track, and the track trolley 7 is limited by the pressure from both sides.

[0041] As a preferred embodiment of the present invention, a friction plate 3 for increasing the friction between the limit plate 1 and the rail trolley 7 is provided on the side of the limit plate 1 facing the adjacent rail, and the friction plate 3 is located at the position where the limit plate 1 contacts the rail trolley 7.

[0042] A positioning plate 4 along the length direction of the adjacent track is also installed on the side of the limiting plate 1 away from the adjacent track. A through hole is opened on the upper end of the positioning plate 4. Correspondingly, a through hole is also opened on the upper end of the limiting plate 1 away from the rotating shaft 2. A reset spring 5 is installed between the two through holes to cooperate with Figure 4 When the side of the limit plate 1 is in contact with the side of the rail trolley 7, the return spring 5 is in an extended state; when the output shaft of the driving cylinder 6 is retracted, the return spring 5 can apply a return force to the limit plate 1, causing the limit plate 1 to rotate back to its initial position. When the return spring 5 is in a natural state, the limit plate 1 is not in contact with the rail trolley 7 and is in contact with the positioning plate 4. At this time, the positioning plate 4 can position the limit plate 1.

[0043] In addition, it should be noted that along the forward direction of the rail trolley 7 on any track, the limit plate 1 in the anti-offside device located on one side of the track is provided with one end of the rotating shaft 2 located in front of the other end. This arrangement can avoid the limit plate 1 and the side of the rail trolley 7 from getting stuck, thereby ensuring the smooth movement of the rail trolley 7.

[0044] This embodiment also provides an automated casting production line, in which a set of the above-mentioned anti-offside devices are respectively provided at both ends of the track of the automated casting production line. After the above-mentioned anti-offside devices replace the original anti-offside devices, when the proximity switch of the mobile corner device is touched by the track trolley 7, the control system sends a control instruction to the anti-offside devices on both sides of the track trolley 7, and then drives the output shaft of the cylinder 6 to press the limit plate 1, and the limit plate 1 rotates around the rotation axis 2, so that the side surfaces of the limit plate 1 are respectively close to the side surfaces of the track trolley 7, and the track trolley 7 is limited by the pressure from both sides. At this time, even if there is relative movement between the track trolley 7 and the limit plate 1, the output shaft of the drive cylinder 6 and the limit plate 1 are still in a relatively static state, which will not affect the drive cylinder 6, so that the anti-offside device is always in an effective state, avoiding the phenomenon of the track trolley 7 overturning and stopping production due to the failure of the anti-offside system in the casting production line.

[0045] Therefore, the present invention keeps the anti-offside device in an effective state at all times, thereby avoiding the phenomenon of the rail trolley 7 rolling over and stopping production in the casting production line due to failure of the anti-offside system.
