Abstract
Description
Technical Field
[0001] This utility model relates to the field of transportation technology, and in particular to an elastic buffer support device for transporting bar stock. Background Technology
[0002] In modern industrial production, bar stock, as a basic material, is widely used in many fields such as construction, machinery manufacturing, and automotive industry. The production, processing, and transportation of bar stock are very complex, and the transportation link plays a crucial role in ensuring the quality of bar stock. In the process of bar stock transportation, transfer trolleys are one of the commonly used transportation tools. However, existing transfer trolleys often have some design flaws, especially when dealing with complex road conditions, lacking effective shock absorption measures, which brings many problems to bar stock transportation.
[0003] Traditional transport trolleys are typically just simple frame structures with wheels used to carry bar stock. When the trolley travels on uneven surfaces or on outdoor roads such as gravel roads or speed bumps, the wheels are subjected to impact forces from the road surface. Due to the lack of shock-absorbing components, these impact forces are directly transmitted to the bar stock on the trolley. Bar stock is a slender material, and its structure makes it prone to swaying, displacement, and even deformation when subjected to vibration and impact. This can lead to collisions between the bar stock. Such collisions can cause defects such as scratches and dents on the surface of the bar stock. For bar stock used in precision machinery manufacturing industries with extremely high requirements for surface quality, even minor surface damage can affect the performance and quality of subsequent products.

This device addresses the issue that transfer trolleys are usually just simple frame structures with wheels used to carry bar stock. When the trolley travels on uneven roads or in outdoor conditions such as gravel roads or speed bumps, the wheels are subjected to impact forces from the road surface. Due to the lack of shock-absorbing components, these impact forces are directly transmitted to the bar stock on the trolley. Bar stock is a slender material, and its structure makes it prone to shaking, displacement, and even deformation when subjected to vibration and impact, leading to collisions between the bar stock. Such collisions can cause defects such as scratches and dents on the surface of the bar stock. For bar stock used in precision machinery manufacturing industries with extremely high surface quality requirements, even minor surface damage can affect the performance and quality of subsequent products.

[0019] 1. This elastic buffer support device for transporting bar stock utilizes an elastic buffer assembly.

[0030] Please see Figure 1-4 This utility model provides a technical solution: an elastic buffer support device for transporting bar stock, including a trolley 1, a top plate 4, an upper clamping seat 5, a lower clamping seat 6, and multiple limiting seats 7;
[0031] The interior of the trolley 1 is equipped with a flexible cushioning component;
[0032] The elastic buffer assembly includes three dampers 12 and four fixing rods 13. Two fixing rod slots 11 are opened on both sides of the inner wall of the trolley 1. The four fixing rods 13 are fixedly installed inside the fixing rod slots 11. Two protrusions 15 are fixedly installed on both sides of the lower surface of the lower clamping seat 6. The lower outer wall of the lower clamping seat 6 is slidably connected to the upper inner wall of the trolley 1. The four protrusions 15 are slidably connected to the outer walls of the corresponding fixing rods 13. The outer walls of the four fixing rods 13 are all fitted with buffer springs 10. The two ends of the four buffer springs 10 are fixedly connected to the outer walls of the corresponding protrusions 15 and the inner walls of the fixing rod slots 11, respectively. The three dampers 12 are fixedly installed inside the trolley 1. A handle is provided at the rear end of the trolley 1. The ends of the three dampers 12 away from the trolley 1 are fixedly connected to the lower surface of the lower clamping seat 6. Four universal wheels are provided at the lower end of the trolley 1.
[0033] The lower clamping seat 6 has four support rods 2 fixedly connected to its upper surface. The lower surface of the top plate 4 is fixedly connected to the end of each support rod 2 away from the lower clamping seat 6. A rotating threaded rod 3 is threadedly connected to the upper surface of the top plate 4. The four sides of the upper clamping seat 5 are slidably connected to the outer walls of the corresponding support rods 2. The end of the rotating threaded rod 3 near the upper clamping seat 5 extends threadedly to the outside of the top plate 4 and is rotatably connected to the upper surface of the upper clamping seat 5. Multiple T-shaped slots 8 are formed on the outer walls of the opposite sides of both the lower clamping seat 6 and the upper clamping seat 5. The T-shaped slots 8 on the upper clamping seat 5 and... The T-shaped block slots 8 on the lower clamping seat 6 are positioned opposite each other. The outer walls of multiple limiting seats 7 are fixedly connected with T-shaped blocks 14. The outer walls of multiple T-shaped blocks 14 are slidably connected to the interior of the corresponding T-shaped block slots 8. The interior of multiple T-shaped block slots 8 is provided with fixing bolt slots 16. The outer walls of multiple T-shaped blocks 14 are threadedly connected with fixing bolts 9. The ends of multiple fixing bolts 9 near the fixing bolt slots 16 are threaded into the interior of the T-shaped block slots 8 and are threadedly connected to the interior of the corresponding fixing bolt slots 16. The opposing surfaces of multiple limiting seats 7 are all arc-shaped.
[0034] Furthermore, when using the device, first push the device to the bar storage area. According to the diameter of the bar, the operator manually rotates the rotating threaded rod 3 on the top plate 4. Since the rotating threaded rod 3 is threadedly connected to the top plate 4 and its lower end is rotatably connected to the upper clamping seat 5, as the rotating threaded rod 3 rotates, the upper clamping seat 5 will move downward along the support rod 2, so that the initial distance between the upper and lower clamping seats is slightly larger than the diameter of the bar. Then, place the bar on the arc surface of the sliding limit seat 7 on the upper surface of the lower clamping seat 6, and then rotate the rotating threaded rod 3 again, driving the upper clamping seat 5 to continue to move downward. The upper clamping seat 5 cooperates with the lower clamping seat 6 to clamp the bar in the middle. As the upper clamping seat 5 moves downward, the bar is tightly fixed in the clamping space formed by the upper and lower clamping seats and the limit seat 7, ensuring that the bar will not shift or roll during transportation. Then, during transportation, when the trolley 1 encounters uneven road surfaces or is subjected to vibration and impact, the lower clamping seat 6 will slide up and down on the upper inner wall of the trolley 1 due to the external force. At this time, the protrusion 15 connected to the lower clamping seat 6 slides along the fixed rod 13, compressing or stretching the buffer spring 10. The buffer spring 10 absorbs part of the vibration energy through elastic deformation, playing a preliminary buffering role. At the same time, the three dampers 12 are activated, consuming vibration energy through the damping effect of the internal medium, reducing the vibration amplitude and frequency of the lower clamping seat 6, and working together with the buffer spring 10 to further improve the buffering effect, reduce the impact of vibration on the bar, and prevent the bar from being damaged by vibration. Meanwhile, due to the four universal wheels at the lower end of the trolley 1, the operator can easily push the device through the handle at the rear end of the trolley 1 to flexibly transport the bar between different sites. After transportation to the destination.
[0035] When the trolley 1 encounters uneven road surfaces or is subjected to vibration and impact, the lower clamping seat 6 slides up and down against the inner wall of the upper end of the trolley 1 due to the external force. At this time, the protrusion 15 connected to the lower clamping seat 6 slides along the fixed rod 13, compressing or stretching the buffer spring 10. The buffer spring 10 absorbs part of the vibration energy through elastic deformation, playing a preliminary buffering role. At the same time, the three dampers 12 are activated, consuming vibration energy through the damping effect of the internal medium, reducing the vibration amplitude and frequency of the lower clamping seat 6, and working together with the buffer spring 10 to further improve the buffering effect, reduce the impact of vibration on the bar, prevent the bar from being damaged by vibration, and thus effectively protect the bar from surface damage.
[0036] Structural Description: Trolley 1: As the basic load-bearing structure of the device, trolley 1 is equipped with four casters at the bottom, which facilitates the flexible movement of the device in various sites. A handle is provided at the rear end for easy pushing by the operator. Two fixing rod slots 11 are opened on the inner walls on both sides for installing fixing rods 13. The internal space is used to house the elastic buffer assembly, including three dampers 12 and four fixing rods 13. The upper inner wall is slidably connected to the lower clamping seat 6, providing space for the sliding and buffering movement of the lower clamping seat 6.
[0037] Support rod 2: Four support rods 2 are fixedly connected to the upper surface of the lower clamping seat 6, extending vertically upward, and the top is fixedly connected to the lower surface of the top plate 4. On the one hand, they support the top plate 4 and maintain the relative position stability between the top plate 4 and the lower clamping seat 6. On the other hand, they provide guidance for the upper clamping seat 5 to slide up and down along its outer wall.
[0038] Rotating threaded rod 3: It is threadedly connected to the center of the upper surface of the top plate 4. The lower end passes through the top plate 4 and is rotatably connected to the upper surface of the upper clamping seat 5. By manually rotating the threaded rod 3, the upper clamping seat 5 can be precisely controlled to move up and down along the support rod 2 using the thread transmission principle, so as to adjust the clamping distance of bars of different diameters.
[0039] Top plate 4: It is fixedly connected to the lower clamping seat 6 by four support rods 2, forming the top frame of the device. Top plate 4 provides an installation base for rotating threaded rod 3, and together with the lower clamping seat 6 and support rods 2, it forms a stable three-dimensional structure to ensure the stability of the upper clamping seat 5 and the limiting seat 7 when clamping the rod.
[0040] Upper clamping seat 5: Its four sides are slidably connected to the outer walls of the four support rods 2 respectively, and can move up and down in the vertical direction under the guidance of the support rods 2. Multiple T-shaped block grooves 8 are provided on the outer wall of its opposite side for installing the limiting seat 7. By rotating the threaded rod 3, it can cooperate with the lower clamping seat 6 to realize the clamping or loosening action of the bar.
[0041] The lower clamping seat 6 has a sliding engagement with the upper inner wall of the trolley 1, allowing for up-and-down buffer sliding on the trolley 1. Two protrusions 15 are fixedly installed on each of the lower surfaces on both sides. The protrusions 15 are slidably connected to the outer wall of the fixing rod 13, and the outer wall of the fixing rod 13 is fitted with a buffer spring 10. The two ends of the spring are respectively connected to the protrusions 15 and the inner wall of the fixing rod groove 11. The lower surface of the lower clamping seat 6 is also fixedly connected to three dampers 12 to form an elastic buffer assembly. The upper surface is connected to the support rod 2. The outer wall on the opposite side is also provided with multiple T-shaped block grooves 8 corresponding to the position of the upper clamping seat 5, which are used to cooperate with the upper clamping seat 5 to install the limiting seat 7.
[0042] Limiting seat 7: The outer wall is fixedly connected to the protrusion 15, which can slide in the T-shaped block groove 8 of the upper and lower clamping seats to achieve position adjustment. The opposite surface of the limiting seat 7 is designed to be arc-shaped, which can closely fit the cylindrical surface of the bar and play a precise limiting role to prevent the bar from rolling or shifting during transportation. Multiple limiting seats 7 can be flexibly installed in the T-shaped block groove 8 of the upper and lower clamping seats according to the actual length, quantity and distribution requirements of the bar.
[0043] Fixing bolt 9: The fixing bolt 9 is threaded to the outer wall of the limiting seat 7. One end of the bolt passes through the protrusion 15 of the limiting seat 7 and extends into the fixing bolt groove 16 in the T-shaped block groove 8. By tightening the fixing bolt 9, the limiting seat 7 can be firmly fixed in the designated position of the T-shaped block groove 8, ensuring that the limiting seat 7 will not loosen during transportation and ensuring the reliability of bar clamping.
[0044] Buffer spring 10: The buffer spring 10 is sleeved on the outer wall of the four fixed rods 13, and its two ends are fixedly connected to the outer wall of the protrusion 15 of the lower clamping seat 6 and the inner wall of the fixed rod groove 11 of the trolley 1, respectively. When the device is subjected to vibration or impact, the buffer spring 10 is compressed or stretched by force, and absorbs vibration energy through elastic deformation, reduces the vibration amplitude of the lower clamping seat 6, and plays a preliminary buffer protection role for the rod.
[0045] Dampers 12: Three dampers 12 are fixedly installed inside the trolley 1, and the other end is fixedly connected to the lower surface of the lower clamping seat 6. When the device vibrates, the dampers 12 use the damping characteristics of the internal medium to consume vibration energy, suppress the vibration frequency and amplitude of the lower clamping seat 6, and work together with the buffer spring 10 to improve the overall buffering effect.
[0046] Fixed rod 13: Fixedly installed in the fixed rod groove 11 of the trolley 1, vertically set, its outer wall is slidably connected to the protrusion 15 of the lower clamping seat 6, providing guidance for the up and down movement of the lower clamping seat 6, and at the same time serving as the mounting carrier of the buffer spring 10, together with the buffer spring 10 and the damper 12, forming an elastic buffer system.
[0047] Protrusion 15: It is fixed on the lower surface of both sides of the lower clamping seat 6 and the outer wall of the limiting seat 7 respectively. The protrusion 15 of the lower clamping seat 6 cooperates with the fixing rod 13 to realize the sliding and buffering of the lower clamping seat 6. The protrusion 15 of the limiting seat 7 cooperates with the T-shaped block groove 8 of the upper and lower clamping seats for the installation, positioning and fixing of the limiting seat 7.
[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
