Description

Technical Field

[0001] This application relates to the field of traveling wheel technology, and in particular to a shock-absorbing and noise-reducing traveling wheel for a stacker crane. Background Technology

[0002] In modern logistics and warehousing systems, stacker cranes are an important handling equipment that undertakes the tasks of handling and storing goods. The wheels of the stacker crane are one of its key components, and the performance of the wheels directly affects the operational stability, reliability and work efficiency of the stacker crane.

[0003] Traditional stacker crane wheels present several problems during operation. First, due to the unevenness of the warehouse floor, the wheels generate significant vibration and noise when rolling. This vibration not only affects the structural stability of the stacker crane but can also lead to loosening and damage of parts over time, increasing maintenance costs. Simultaneously, the noise pollution also impacts the working environment and affects the physical and mental health of workers.

[0004] Secondly, adjusting the position of traditional wheels is inconvenient. In actual use, the position of the wheels may need to be adjusted according to different work requirements and warehouse layout. However, the existing wheel adjustment methods often require a lot of time and manpower, are complicated to operate, and are inefficient. This limits the flexibility and efficiency of stacker cranes to a certain extent.

[0005] To address this issue, a shock-absorbing and noise-reducing stacker crane traveling wheel was invented to solve the problems mentioned in the background technology. Utility Model Content

[0006] The purpose of this invention is to provide a shock-absorbing and noise-reducing stacker crane traveling wheel to solve the problems of large vibration, high noise, and inconvenient position adjustment of traditional stacker crane traveling wheels during operation.

[0007] The shock-absorbing and noise-reducing stacker crane traveling wheel provided in this application adopts the following technical solution: it includes a fixed base, wherein a traveling wheel assembly is provided on the fixed base, a shock-absorbing mechanism for shock absorption of the traveling wheel assembly is provided between the traveling wheel assembly and the fixed base, a connecting seat assembly is provided on the fixed base, the connecting seat assembly includes a first connecting seat and a second connecting seat, the first connecting seat and the second connecting seat can slide relative to each other, and a driving mechanism for driving the first connecting seat and the second connecting seat to slide relative to each other is provided on the connecting seat assembly.

[0008] Optionally, the shock absorption mechanism includes a swing arm, which is hinged to the fixed base. A plug rod is hinged to the fixed base. A support seat is provided on the top of the walking wheel assembly. A plug cylinder is hinged to the support seat. The plug rod can be inserted into the plug cylinder. A fixed compression spring is provided on the plug cylinder, and the other end of the fixed compression spring is fixedly connected to the plug rod. The other end of the swing arm is hinged to the support seat.

[0009] Optionally, the walking wheel assembly includes a fixed shaft, which is rotatably connected to a support base. An annular rubber protective sleeve is provided on the outer side of the fixed shaft. Several first compression springs are connected between the rubber protective sleeve and the support base, and an elastic ring is provided between two adjacent first compression springs.

[0010] Optionally, the driving mechanism includes a rotating rod rotatably connected to a second connecting seat. The first connecting seat has a threaded hole, and the rotating rod has a thread. The rotating rod is inserted into the threaded hole and threadedly connected to the first connecting seat. One end of the rotating rod is provided with a rotating handwheel.

[0011] Optionally, the bottom four corners of the connecting seat assembly are provided with a number of threaded limiting holes, and the fixed base is provided with limiting bolts that can be threadedly engaged with the threaded limiting holes. By inserting the limiting bolts into different threaded limiting holes, the position of the traveling wheel assembly can be adjusted.

[0012] Optionally, the first connecting seat has a plurality of fixing through holes, and the second connecting seat has fixing rods that correspond one-to-one with the fixing through holes.

[0013] In summary, this application includes the following beneficial technical effects: In the shock absorption mechanism, the swing arm, insert rod, insert cylinder and fixed compression spring work together. When the traveling wheel encounters vibration, the elastic deformation of the fixed compression spring can efficiently absorb the vibration energy, and the swing arm swing further assists in buffering, greatly reducing the impact of vibration on the stacker crane structure and significantly improving the stability of the equipment. The rubber protective sleeve in the walking wheel assembly, together with the first compression spring and elastic ring, can effectively buffer the impact force of the ground and reduce the transmission of vibration when the walking wheel rolls. The properties of the rubber protective sleeve itself can also greatly reduce noise generation, creating a quieter working environment for the staff. The drive mechanism is connected to the threaded hole via a rotating rod. By simply turning the handwheel, the relative sliding of the first connecting seat and the second connecting seat can be easily achieved, thereby conveniently adjusting the position of the traveling wheel assembly. Combined with the precise positioning of the limit bolt and the threaded limit hole, the position adjustment is more efficient and accurate, greatly improving the flexibility of the stacker crane.

[0016] Reference Figure 1 , Figure 2 One embodiment shown is as follows: The shock-absorbing and noise-reducing stacker crane's traveling wheel includes a fixed base 1. In this embodiment, the fixed base 1 serves as the basic support component for the entire traveling wheel, with a traveling wheel assembly 2 mounted on top of it. The traveling wheel assembly 2 directly contacts the running track or the ground, undertaking the traveling function. A shock-absorbing mechanism 3 is provided between the traveling wheel assembly 2 and the fixed base 1 to reduce the impact of vibrations generated during the traveling wheel's operation on the fixed base 1 and the stacker crane as a whole. A connecting seat assembly 4 is also provided on the fixed base 1. The connecting seat assembly 4 consists of a first connecting seat 5 and a second connecting seat 6, which can slide relative to each other to adjust the position of the traveling wheel assembly 2. A drive mechanism 7 on the connecting seat assembly 4 can drive the first connecting seat 5 and the second connecting seat 6 to slide relative to each other, realizing convenient adjustment of the position of the traveling wheel assembly 2.

[0017] The implementation principle of the above embodiment is as follows: the fixed base 1 provides stable support; the walking wheel assembly 2 vibrates during operation, and the shock absorption mechanism 3 plays a shock absorption role; when it is necessary to adjust the position of the walking wheel assembly 2, the drive mechanism 7 works, causing the first connecting seat 5 and the second connecting seat 6 to slide relative to each other, thereby changing the position of the walking wheel assembly 2. Through this structural design, the normal operation of the walking wheel is ensured, and shock absorption and position adjustment functions are realized.

[0018] Reference Figure 1 , Figure 2 One embodiment shown is as follows: The shock absorption mechanism 3 includes a fixed base 1. In this embodiment, a swing rod 8 and a plug rod 9 are hinged to the fixed base 1, providing a rotational connection point for the swing rod 8 and the plug rod 9. A support seat 10 is provided on the top of the traveling wheel assembly 2, and the traveling wheel assembly 2 is rotatably connected to the support seat 10. A plug cylinder 11 is hinged to the support seat 10, and the plug cylinder 11 cooperates with the plug rod 9, allowing the plug rod 9 to be inserted into the plug cylinder 11. A fixed compression spring is fixedly fitted on the plug cylinder 11, and the other end of the fixed compression spring is fixedly connected to the plug rod 9. The other end of the swing rod 8 is also hinged to the support seat 10. This connection relationship makes the shock absorption mechanism 3 form a linked buffer structure.

[0019] The implementation principle of the above embodiment is as follows: When the traveling wheel assembly 2 vibrates due to uneven ground, the support base 10 moves up and down with the vibration, the insertion rod 9 slides inside the insertion cylinder 11, and the fixing spring is compressed or stretched, using its elastic deformation to absorb vibration energy. At the same time, the swing rod 8 swings with the support base 10, sharing part of the vibration impact force, effectively buffering the vibration of the traveling wheel assembly 2, and reducing the impact of vibration on the overall structure of the stacker crane.

[0020] Reference Figure 5 One embodiment shown is as follows: The walking wheel assembly 2 includes a fixed shaft 12. In this embodiment, the fixed shaft 12 is rotatably connected to a support base 10, which provides support for the fixed shaft 12, allowing it to rotate freely. An annular rubber protective sleeve 13 is provided on the outer side of the fixed shaft 12. The rubber protective sleeve 13 is in direct contact with the ground, serving as a buffer and noise reduction function. Several first compression springs 14 are connected between the rubber protective sleeve 13 and the support base 10, and elastic rings 15 are fixedly arranged between adjacent first compression springs 14. The first compression springs 14 and elastic rings 15 work together to further enhance the buffering effect.

[0021] The implementation principle of the above embodiment is as follows: When the walking wheel is running, the rubber protective sleeve 13 contacts the ground. When it is impacted by the ground, the first compression spring 14 and the elastic ring 15 deform, buffering the impact and reducing the transmission of vibration to the fixed shaft 12 and the support seat 10. The elastic material of the rubber protective sleeve 13 also plays a role in shock absorption and noise reduction, jointly ensuring the smooth operation of the walking wheel and reducing noise.

[0022] Reference Figure 3 One embodiment shown is as follows: The drive mechanism 7 includes a rotating rod 16, which is rotatably connected to the second connecting seat 6 via a bearing. The bearing provides stable support for the rotating rod 16, ensuring smooth rotation. A threaded hole 17 is precisely machined into the first connecting seat 5, and a matching thread is machined onto the rotating rod 16. The rotating rod 16 is inserted into the threaded hole 17, and the two are connected by a thread to transmit power. A handwheel 18 is provided at one end of the rotating rod 16 via a key connection or welding. The key connection ensures that the handwheel 18 rotates synchronously with the rotating rod 16, allowing the operator to rotate the rotating rod 16 by turning the handwheel 18. The threaded connection enables relative sliding between the first connecting seat 5 and the second connecting seat 6.

[0023] The implementation principle of the above embodiment is as follows: When it is necessary to adjust the position of the walking wheel assembly 2, rotate the rotating handwheel 18, and the rotating rod 16 rotates on the second connecting seat 6. Due to the threaded connection, the rotation of the rotating rod 16 causes the first connecting seat 5 to slide relative to the second connecting seat 6, thereby realizing the adjustment of the position of the walking wheel assembly 2. The operation is simple and convenient.

[0024] Reference Figure 1 One embodiment is shown whereby a plurality of threaded limiting holes 19 are machined at the four corners of the bottom of the connecting seat assembly 4. The precision of the threaded limiting holes 19 ensures a tight fit with the limiting bolts 20. The fixed base 1 is equipped with limiting bolts 20 that can be threaded into the threaded limiting holes 19. The screw portion of the limiting bolt 20 precisely matches the internal thread of the threaded limiting hole 19. After the drive mechanism 7 adjusts the position of the traveling wheel assembly 2, the limiting bolts 20 are screwed into the corresponding threaded limiting holes 19, and the position of the traveling wheel assembly 2 is fixed by tightening the limiting bolts 20.

[0025] The implementation principle of the above embodiment is as follows: During the process of adjusting the position of the walking wheel assembly 2 by the drive mechanism 7, each time it is adjusted to a suitable position, the position of the walking wheel assembly 2 can be fixed by the cooperation of the limit bolt 20 and the different thread limit holes 19, so as to ensure that the position of the walking wheel is stable during operation and avoid position deviation due to vibration or other reasons.

[0026] Reference Figure 6 One embodiment shown is as follows: a plurality of fixing through holes 21 are drilled on the first connecting seat 5. The diameter of the fixing through holes 21 is adapted to the outer diameter of the fixing rod 22 on the second connecting seat 6. The second connecting seat 6 is provided with fixing rods 22 corresponding to the fixing through holes 21 one by one by welding or bolting. The length and shape design of the fixing rod 22 ensures that it can be smoothly inserted into the fixing through holes 21. The insertion of the fixing rod 22 into the fixing through holes 21 realizes the relative positioning of the first connecting seat 5 and the second connecting seat 6 in the horizontal direction and part of the vertical direction.

[0027] The implementation principle of the above embodiment is as follows: During the operation of the walking wheel, the first connecting seat 5 and the second connecting seat 6 will be subjected to various forces. The fixing rod 22 is inserted into the fixing through hole 21, which restricts the relative displacement of the two connecting seats in the horizontal direction. This ensures that the connecting seat assembly 4 can maintain a stable connection state when the drive mechanism 7 adjusts its position and when the walking wheel is running, thereby enhancing the connection stability and ensuring the normal operation of the stacker crane.

[0028] The working principle of this device is as follows: When the traveling wheel vibrates on uneven ground, the support base 10 moves up and down with the vibration. The swing rod 8, hinged to the support base 10, begins to swing, sharing part of the vibration impact force. At the same time, the insertion rod 9 slides up and down inside the insertion cylinder 11. Since one end of the fixed compression spring on the insertion cylinder 11 is fixedly connected to the insertion rod 9, the fixed compression spring is compressed or stretched, using its elastic deformation to absorb vibration energy, thereby effectively buffering the vibration of the traveling wheel assembly 2 and reducing the impact of vibration on the overall structure of the stacker crane. During the rolling process of the traveling wheel, the rubber protective sleeve 13 is in direct contact with the ground. When subjected to ground impact force, several first compression springs 14 connected between the rubber protective sleeve 13 and the support base 10 deform, and the elastic ring 15 between two adjacent first compression springs 14 also deforms in coordination, jointly buffering the impact force and reducing the transmission of vibration to the fixed shaft 12 and the support base 10. Furthermore, the elastic material of the rubber protective sleeve 13 itself can play a role in shock absorption and noise reduction, ensuring the smooth operation of the traveling wheel and reducing noise. When the position of the walking wheel assembly 2 needs to be adjusted, rotate the handwheel 18 at one end of the rotating rod 16. The rotating rod 16 rotates on the second connecting seat 6 via a bearing. Because the rotating rod 16 is threadedly connected to the first connecting seat 5, the rotation of the rotating rod 16 will cause the first connecting seat 5 to slide relative to the second connecting seat 6, achieving a preliminary adjustment of the position. After the adjustment is in place, insert the limiting bolts 20 on the fixed base 1 into the threaded limiting holes 19 at the four corners of the bottom of the connecting seat assembly 4 to fix the position of the walking wheel assembly 2 and ensure that the position is stable during operation.

[0029] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
