Abstract
Description
Technical Field
[0001] This utility model relates to the field of material pushing systems, specifically a large-stroke material pushing system. Background Technology
[0002] The material pushing system is an auxiliary device in the one-time automatic loading industry. It includes a gantry located at the rear of the car body and a material pushing mechanism that is lifted and installed in the gantry. When all the materials in a car are transported to the rear of the car body by the conveying mechanism, the material pushing mechanism of the material pushing system descends and pushes the materials in the car body forward to complete the one-time loading.
[0003] In existing technologies, conventional material pushing mechanisms typically include several hydraulic cylinders mounted on a lifting frame and a pusher plate located at the front end of the cylinders. The extension and retraction stroke of the hydraulic cylinders generally only extends until the pusher plate is pushed to the rear end of the carriage to complete the material pushing. However, in the field of automated loading, there are materials with high density and small volume, such as zinc ingots and iron ingots. When these types of materials reach the vehicle load, their overall length is shorter than the length of the carriage, requiring hydraulic cylinders with longer strokes to push them against the front wall of the carriage. Conventional material pushing mechanisms cannot meet this requirement, resulting in materials being pushed only to the middle or rear of the vehicle, affecting driving safety and easily leading to situations such as tipping or scattering, greatly reducing loading stability.
[0004] The research objective of this utility model is to design a long-stroke feeding system to address the problems existing in the prior art. Utility Model Content
[0005] To address the problems existing in the prior art, this utility model provides a long-stroke feeding system that can effectively solve the problems existing in the prior art.
[0006] The technical solution of this utility model is: A long-stroke feeding system includes: Frame; The lifting mechanism includes a lifting frame that is movably mounted on the frame and driven to move up and down by a lifting drive device, and a support frame that is connected to the lifting frame and extends rearward. The material pushing mechanism includes a telescopic frame that moves back and forth through the lifting frame and the support frame, a drive cylinder disposed on the lifting frame and the support frame and used to drive the telescopic frame to extend and retract back and forth, the front end of the telescopic frame is provided as a material pushing part for pushing materials, and the lifting frame is provided with a limiting device that moves against the telescopic frame and is used to limit the sway of the telescopic frame; the telescopic frame is used to extend forward until the material pushing part extends into the corresponding carriage to push materials.
[0007] Furthermore, the frame is configured as a gantry, and the lifting frame and telescopic frame are configured as a hollow square column. The two ends of the lifting frame are slidably disposed inside the gantry. The support frame includes a connecting part that is vertically disposed and attached to the rear side of the lifting frame, a support part that is vertically disposed at the rear side of the lower end of the connecting part and extends rearward, and a reinforcing part that connects the rear end of the support part and the upper end of the connecting part.
[0008] Furthermore, the lifting frame has a square column-shaped channel running through it from front to back, allowing the telescopic frame to extend and retract. The limiting device includes a plurality of first rollers and a plurality of second rollers that are rotatably disposed within the lifting frame. The plurality of first rollers are symmetrically arranged in pairs on the upper and lower sides of the channel, and the plurality of second rollers are symmetrically arranged in pairs on the left and right sides of the channel. Each group of first rollers is respectively limited and rolled on the upper and lower sides of the telescopic frame, and each group of second rollers is respectively limited and rolled on the left and right sides of the telescopic frame. The telescopic frame is extended and retracted in a straight line from front to back by the limiting of the plurality of first rollers and the plurality of second rollers.
[0009] Furthermore, the first rollers are divided into four groups of two, and the second rollers are divided into two groups of two. The four groups of first rollers are respectively located on the front and rear sides of the upper and lower ends of the channel, and the two groups of second rollers are respectively located on the lower sides of the left and right ends of the channel. Adjacent first rollers and second rollers are arranged at right angles and are rolled and clamped on the left and right sides of the lower end of the telescopic frame.
[0010] Furthermore, the support frame is provided with a plurality of third rollers for rolling support of the telescopic frame. The number of the third rollers is set to two and they are respectively located on the left and right sides of the rear end of the support part. The two third rollers roll against the left and right sides of the bottom of the telescopic frame.
[0011] Furthermore, the pushing part is configured as a pushing panel covering the front end of the telescopic frame, the telescopic end of the drive cylinder is connected to the front end of the telescopic frame, the lifting stroke of the lifting frame is 1.2m-1.4m, the telescopic stroke of the pushing part is 3.7m-3.9m, the front end of the telescopic frame is provided with several support wheels that rotate back and forth, the bottom of the support wheels protrudes downward from the bottom of the pushing panel, when the pushing part extends into the corresponding carriage to push material, the several support wheels roll and move inside the carriage.
[0012] Therefore, the beneficial effects of this utility model are: 1. By extending the support frame, a longer-stroke telescopic frame can be added, and the cylinder stroke can be extended, thereby increasing the pushing stroke of the pushing system. When the loaded material is high-density and small-volume, resulting in a short overall length of the material in the vehicle, the telescopic frame can be driven by the cylinder to extend forward to the pushing section and into the corresponding compartment for pushing. This achieves a stable loading effect, even when the overall length of the material is short, by pushing it against the front wall of the compartment, thus improving the loading adaptability and stability of the one-time loading system. Furthermore, the setting of the limiting device can not only stably guide the forward and backward extension of the telescopic frame, but also improve the pushing effect. Stability is ensured to prevent uneven force distribution during material pushing, which could lead to swaying, tilting, or jamming of the telescopic frame. It also connects the telescopic frame to the lifting frame and support frame, allowing the force during material pushing to be distributed not only to the drive cylinder but also to the lifting and support frames via a limiting device. This reduces the pressure on the cylinder during pushing, especially when uneven force distribution on the left / right or top / bottom sides of the pushing section causes the telescopic frame to sway left / right or top / bottom. The lifting and support frames can distribute most of the pressure, reducing the risk of excessive pressure on the cylinder and improving the pushing stability of the mechanism.
[0013] 2. By setting the lifting frame to a directional position and allowing both ends to slide up and down within the gantry, the structural strength and vertical sliding stability of the lifting frame can be improved. By vertically setting the connecting part and the reinforcing part and setting the reinforcing part connecting the two, the overall structural strength of the support frame is improved. The close connection of the connecting part improves the connection strength between the support frame and the lifting frame, thereby improving the overall structural strength of the pushing mechanism, and further improving the support strength of the support frame and the lifting frame for the telescopic frame. Moreover, while ensuring the structural strength of the support frame, the material used in the support frame can be reduced to reduce weight and alleviate the driving burden of the lifting drive device.
[0014] 3. By using the up-and-down rolling limit of several first rollers and the left-and-right rolling limit of several second rollers, the bidirectional limit of the cylindrical telescopic frame is achieved, ensuring that it extends and retracts in a straight line, thereby ensuring the stability of the material pushing. In addition, the limit guide is achieved by using rollers, which can avoid friction or collision between the telescopic frame and the lifting frame or support frame during the extension and retraction, thus avoiding damage. Under the premise of achieving the limit function, the limit effect of the limit device is improved.
[0015] 4. By strategically positioning four sets of first rollers and two sets of second rollers, the telescopic frame located within the channel is guided vertically from all four directions (front, back, left, and right) and horizontally from both the front and back. This improves the uniformity of the first rollers' vertical guidance of the telescopic frame and enhances the lateral guidance strength of the second rollers on the lower side of the telescopic frame. When the material pusher descends to the rear of the vehicle's material and pushes it, it is mainly subjected to downward pressure and uneven weight distribution of the material on both sides, causing the telescopic frame to tend to sway vertically and horizontally. By using adjacent first and second rollers positioned at right angles to roll and clamp the lower left and right sides of the telescopic frame, the limiting effect of the limiting device on the telescopic frame is improved, and the efficiency of distributing the force of the telescopic frame to the lifting frame is increased.
[0016] 5. By setting up support wheels, when the pushing part extends into the corresponding carriage to push the material, several support wheels roll and move within the carriage. The rolling movement of the support wheels supports and distributes the weight and force of the telescopic frame after its long stroke extension, and transmits it to the rear of the carriage to disperse it. This avoids the situation where the telescopic frame is damaged due to excessive pressure after its long stroke extension, and greatly improves the stability of the telescopic frame after its extension.

[0018] Figure 2 This is a structural diagram of the lifting frame and support frame.
[0019] Figure 3 This is a schematic diagram of the feeding mechanism. Detailed Implementation
[0020] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings: refer to Figure 1-3 A long-stroke feeding system, comprising: Frame 1; The lifting mechanism 2 includes a lifting frame 21 that is movably mounted on the frame 1 and driven to move up and down by the lifting drive device 23, and a support frame 22 that is connected to the lifting frame 21 and extends backward. The material pushing mechanism 3 includes a telescopic frame 31 that moves back and forth through the lifting frame 21 and the support frame 22, and a drive cylinder 32 disposed on the lifting frame 21 and the support frame 22 for driving the telescopic frame 31 to extend and retract back and forth. The front end of the telescopic frame 31 is provided as a material pushing part 311 for pushing materials. The lifting frame 21 is provided with a limiting device that moves against the telescopic frame 31 and is used to limit the sway of the telescopic frame 31. The telescopic frame 31 is used to extend forward to the material pushing part 311 and extend into the corresponding carriage to push materials.
[0021] The aforementioned structure, through the extension of the support frame 22, allows for the addition of a long-stroke telescopic frame 31, extending the cylinder stroke and thus increasing the pushing stroke of the pushing system. When the loading material is a high-density, small-volume material, resulting in a short overall length, the telescopic frame 31 can be driven by the cylinder to extend forward to the pushing part 311 and into the corresponding compartment for pushing. This achieves a stable loading effect, even when the overall length of the material is short, by pushing it against the front wall of the compartment, improving the loading adaptability and stability of the one-time loading system. Furthermore, the setting of the limiting device not only provides stable guidance for the forward and backward extension of the telescopic frame 31, thereby improving pushing stability, but also prevents the pushing... When the material pusher 311 experiences uneven force, causing the telescopic frame 31 to wobble, tilt, or jam, the telescopic frame 31 can be connected to the lifting frame 21 and the support frame 22. This allows the force on the material pusher 311 to be distributed not only to the drive cylinder 32 but also to the lifting frame 21 and the support frame 22 through the limiting device. This reduces the pressure on the cylinder during material push, especially when the material pusher 311 experiences uneven force on the left and right or up and down sides, causing the telescopic frame 31 to wobble left and right or up and down. The lifting frame 21 and the support frame 22 can distribute most of the pressure, thereby reducing the risk of damage to the cylinder due to excessive pressure and improving the pushing stability of the material pusher mechanism 3.
[0022] To improve the structural strength of the feeding mechanism 3, the frame 1 is set as a gantry, and the lifting frame 21 and the telescopic frame 31 are set as a hollow square column. The two ends of the lifting frame 21 are slidably arranged in the gantry. The support frame 22 includes a connecting part 221 that is vertically arranged and attached to the rear side of the lifting frame 21, a support part 222 that is vertically arranged on the rear side of the lower end of the connecting part 221 and extends rearward, and a reinforcing part 223 that connects the rear end of the support part 222 and the upper end of the connecting part 221. The above structure improves the structural strength and vertical sliding stability of the lifting frame 21 by setting the lifting frame 21 in a directional position and allowing both ends to slide vertically within the gantry. By vertically arranging the connecting part 221 and the reinforcing part 223 and providing the reinforcing part 223 connecting the two, the overall structural strength of the support frame 22 is improved. The close connection of the connecting part 221 improves the connection strength between the support frame 22 and the lifting frame 21, thereby improving the overall structural strength of the pushing mechanism 3. This, in turn, improves the support strength of the support frame 22 and the lifting frame 21 for the telescopic frame 31. Furthermore, while ensuring the structural strength of the support frame 22, the material used in the support frame 22 can be reduced to decrease weight and reduce the driving burden on the lifting drive device 23.
[0023] Specifically, the lifting frame 21 has a square column-shaped channel 211 that runs through it from front to back, allowing the telescopic frame 31 to extend and retract. The limiting device includes a plurality of first rollers 212 and a plurality of second rollers 213 that are rotatably disposed in the lifting frame 21. The plurality of first rollers 212 are symmetrically arranged in pairs on the upper and lower sides of the channel 211, and the plurality of second rollers 213 are symmetrically arranged in pairs on the left and right sides of the channel 211. Each group of first rollers 212 is respectively limited and rolled and clamped on the upper and lower sides of the telescopic frame 31, and each group of second rollers 213 is respectively limited and rolled and clamped on the left and right sides of the telescopic frame 31. The telescopic frame 31 is extended and retracted in a straight line from front to back by the limiting of the plurality of first rollers 212 and the plurality of second rollers 213. The above structure achieves bidirectional limiting of the opposing column telescopic frame 31 through the vertical rolling limiting of several first rollers 212 and the horizontal rolling limiting of several second rollers 213, ensuring that it extends and retracts in a straight line, thereby ensuring the stability of pushing materials. In addition, the limiting and guiding effect achieved by the rollers can avoid the telescopic frame 31 from being damaged by friction or collision with the lifting frame 21 or the support frame 22 during extension and retraction. Under the premise of achieving the limiting function, the limiting effect of the limiting device is improved.
[0024] To improve the limiting effect of the limiting device, the first rollers 212 are divided into four groups of two, and the second rollers 213 are divided into two groups of two. The four groups of first rollers 212 are respectively located on the front and rear sides of the upper and lower ends of the channel 211, and the two groups of second rollers 213 are respectively located on the lower sides of the left and right ends of the channel 211. Adjacent first rollers 212 and second rollers 213 are arranged at right angles and rolled and clamped on the left and right sides of the lower end of the telescopic frame 31. The above structure, through the positional distribution of four sets of first rollers 212 and two sets of second rollers 213, provides vertical clamping guidance for the telescopic frame 31 located in the channel 211 at four points (front, back, left, and right) and horizontal clamping guidance at two points (front and back). This improves the uniformity of the vertical limiting guidance of the first rollers 212 on the telescopic frame 31 and enhances the horizontal guiding strength of the second rollers 213 on the lower side of the telescopic frame 31. When the pushing part 311 descends to the rear side of the vehicle's material and pushes the material, it is mainly subjected to backward and downward pressure and uneven weight distribution of the material on the left and right sides, causing the telescopic frame 31 to have a tendency to sway vertically and horizontally. The adjacent first rollers 212 and second rollers 213, set at right angles, roll and clamp the lower end of the telescopic frame 31 on the left and right sides, which can improve the limiting effect of the limiting device on the telescopic frame 31 and improve the efficiency of distributing the force of the telescopic frame 31 to the lifting frame 21.
[0025] To improve the smoothness of the telescopic frame 31's extension and retraction, the support frame 22 is provided with a plurality of third rollers 224 for rolling support of the telescopic frame 31. Two third rollers 224 are provided, one on the left and one on the right side of the rear end of the support 222, respectively, and the two third rollers 224 roll against the left and right sides of the bottom of the telescopic frame 31. This structure improves the smoothness of the telescopic frame 31's extension and retraction through the support frame 22 by using the third rollers 224.
[0026] To further improve the stability of the telescopic frame 31 after it extends, the pushing part 311 is configured as a pushing panel covering the front end of the telescopic frame 31. The telescopic end of the drive cylinder 32 is connected to the front end of the telescopic frame 31. The lifting stroke of the lifting frame 21 is 1.2m-1.4m, and the telescopic stroke of the pushing part 311 is 3.7m-3.9m. Preferably, the lifting stroke of the lifting frame 21 is 1.3m, and the telescopic stroke of the pushing part 311 is 3.8m. The front end of the telescopic frame 31 is provided with several support wheels 33 that rotate back and forth. The bottom part of the support wheel 33 protrudes downward from the bottom of the pushing panel. The above structure, through the setting of support wheels 33, allows several support wheels 33 to roll and move within the carriage when the pushing part 311 extends into the corresponding carriage to push the material. This rolling movement of the support wheels 33 supports and distributes the weight and force of the telescopic frame 31 after its long stroke extension, and transmits it to the rear of the carriage for dispersion. This avoids the situation where the telescopic frame 31 is damaged due to excessive pressure after its long stroke extension, and greatly improves the stability of the telescopic frame 31 after its extension.
[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
