[0002] In existing industrial mechanical equipment, especially in three-way stackers for upward movement of personnel, most of the damping adjustment mechanisms of the steering wheel adopt the method of combining traditional bearings and large springs with mounting brackets. Although this design can achieve steering wheel damping adjustment to a certain extent, there are many problems and deficiencies in actual applications.
[0003] Firstly, the existing method of combining bearings and large springs with mounting brackets occupies a large space. Since the cab space of a three-way stacker for upward movement of personnel is usually relatively limited, this large-space-occupying design makes the layout inside the cab more compact, affecting the installation and operation space of other equipment or functions. In addition, the overly large damping adjustment mechanism makes the inside of the cab appear bulky, affecting the comfort and operation experience of the driver. Secondly, there are obvious deficiencies in the flexibility of this adjustment mechanism. The existing damping adjustment methods can usually only be adjusted within a limited range and are difficult to precisely meet the personalized needs of different drivers. Each driver may have different preferences for the steering wheel damping. The existing adjustment methods are difficult to provide sufficient adjustment accuracy and range, resulting in the driver not being able to obtain the best operation feeling and comfort during operation. Additionally, the existing bearing and large spring structures also have certain difficulties in maintenance and upkeep. Due to the complex structure and diverse components, the process of maintaining and replacing parts is rather cumbersome and time-consuming, increasing the maintenance cost and downtime of the equipment. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
[0022] Such as Figure 1 and Figure 2As shown in the figure, a steering wheel damping adjustment mechanism for a three-way stacker for upward movement of people includes a damping spring seat 1, a spring-back part 2, a damping disc 3, a transmission mechanism 4, a steering wheel damping friction sleeve 5, a direction damping gasket 6, and an adjustment mechanism 7. The spring-back part 2 is arranged on the damping spring seat 1, and the damping disc 3 is arranged on the damping spring seat 1 by compressing the spring-back part 2. The transmission mechanism 4 passes through the centers of the damping spring seat 1 and the damping disc 3 and can rotate. The transmission mechanism 4 is provided with a mutually attached steering wheel damping friction sleeve 5 and a direction damping gasket 6. The adjustment mechanism 7 is connected to the transmission mechanism 4, the steering wheel damping friction sleeve 5, and the steering wheel damping gasket 6, and can adjust the compression amount of the spring-back part 2, so that when the transmission mechanism 4 rotates, the tightness of the fit between the steering wheel damping friction sleeve 5 and the steering wheel damping gasket 6 can be changed.
[0023] The core of this steering wheel damping adjustment mechanism is to adjust the compression amount of the spring-back part 2 through the adjustment mechanism 7, so as to control the frictional force between the steering wheel damping friction sleeve 5 and the direction damping gasket 6. When the transmission mechanism 4 rotates, the magnitude of the frictional force directly affects the rotational damping of the steering wheel, enabling the operator to adjust the operating feel of the steering wheel according to requirements. The setting of the spring-back part 2 ensures that the steering wheel can automatically return to its original position after being released, providing a stable operating experience. This design makes the damping adjustment of the stacker steering wheel more flexible and precise, improving the comfort and safety of equipment operation. By adjusting the damping of the steering wheel, the operator can select an appropriate rotational resistance according to different working environments and requirements, enhancing the adaptability of the equipment. At the same time, the structure is simple and easy to manufacture and maintain, reducing costs. By simply adjusting the tightness of the screw, the damping magnitude can be conveniently adjusted to meet the different needs of the driver.
[0024] Different types of spring materials can be used for the spring-back part 2 to achieve different spring-back effects, such as using springs with different elastic coefficients or other spring-back components. In addition, the design of the transmission mechanism 4 can also be adjusted according to needs, such as adopting different drive shaft structures or connection methods to adapt to different installation spaces or operating requirements. Similarly, the adjustment mechanism 7 can achieve more diverse adjustment functions by using different adjustment screws or other adjustment devices.
[0025] The said rebounding part 2 includes a damping spring 21. The damping spring 21 is fixedly connected to the damping spring seat 1 and the damping disc 3. The damping spring 21 is located between the damping spring seat 1 and the damping disc 3, and the damping disc 3 is located above the damping spring seat 1. The damping spring 21 in the rebounding part 2 forms a system capable of providing stable rebounding force through its fixed connection with the damping spring seat 1 and the damping disc 3. When the steering wheel rotates, the transmission mechanism 4 drives the damping disc 3 to compress or release the damping spring 21, thereby adjusting the damping effect of the steering wheel. The elastic force of the damping spring 21 ensures that the steering wheel can quickly return to its original position after the external force is removed, keeping the steering wheel in a controllable state at all times.
[0026] By adopting the damping spring 21, the rebounding performance of the steering wheel damping adjustment mechanism is improved, making the operation of the steering wheel smoother and more stable. This design can effectively prevent the steering wheel from continuing to rotate due to inertia after being released, thereby improving the safety and precision of operation. In addition, the close combination of the damping spring 21 with related components enhances the reliability and durability of the overall structure.
[0027] The material and specifications of the damping spring 21 can be adjusted according to actual requirements. For example, springs with different elastic coefficients or different diameters can be used to achieve more precise damping control. At the same time, the connection method between the damping spring and other components can also adopt a detachable connection for easy maintenance and replacement. In addition, in specific applications, the damping spring 21 can be replaced by other rebounding elements, such as pneumatic springs or hydraulic devices, to adapt to different operating environments and requirements.
[0028] The said transmission mechanism 4 includes a transmission shaft 41. A fixed sleeve 42 is fixedly connected to the outer surface of the transmission shaft 41. The transmission shaft 41 passes through the centers of the damping spring seat 1 and the damping disc 3 and is rotatably connected to the damping spring seat 1 and the damping disc 3. The fixed sleeve 42 is located above the damping disc 3. The core component of the transmission mechanism 4 is the transmission shaft 41. The transmission shaft 41 passes through the centers of the damping spring seat 1 and the damping disc 3 and maintains a rotatable connection with these two components, thus ensuring that the steering wheel can rotate smoothly. The setting of the fixed sleeve 42 ensures the position stability of the transmission shaft 41 during the transmission process and prevents axial movement. The rotation of the transmission shaft 41 drives the damping disc 3 to adjust the angle under the action of the compression force of the damping spring 21, thereby realizing the function of steering wheel damping adjustment.
[0029] Through the design of the transmission shaft 41 and the fixed sleeve 42, the rotation of the steering wheel is made smoother and more accurate. The axial fixation and rotatable connection of the transmission shaft 41 ensure the stability of the transmission mechanism 4 and reduce the problem of uneven steering wheel damping caused by the displacement of the transmission shaft. This design improves the reliability and durability of the entire steering wheel damping adjustment mechanism and is applicable to industrial application scenarios with high intensity and frequent operation.
[0030] The transmission shaft 41 can use different materials or surface treatment processes according to actual needs to enhance its wear resistance and corrosion resistance. At the same time, the design of the fixing sleeve 42 can also be adjusted, such as using an adjustable sleeve structure or adopting different fixing methods to adapt to more complex operating environments or installation requirements. The diameter and length of the transmission shaft can also be appropriately adjusted according to the size of the steering wheel and working requirements to ensure the best transmission effect.
[0031] A direction damping gasket 6 and a steering wheel damping friction sleeve 5 are sleeved on the lower part of the transmission shaft 41 in sequence from bottom to top. The steering wheel damping friction sleeve 5 is located at the bottom of the damping spring seat 1. The transmission shaft 41 is fixedly connected to the direction damping gasket 6 and the steering wheel damping friction sleeve 5. The lower part of the transmission shaft 41 is designed such that the direction damping gasket 6 and the steering wheel damping friction sleeve 5 can be sequentially sleeved on the transmission shaft 41. The direction damping gasket 6 is tightly connected to the transmission shaft 41. The steering wheel damping friction sleeve 5 is located at the bottom of the damping spring seat 1. When the transmission shaft 41 rotates, a frictional force is generated between the steering wheel damping friction sleeve 5 and the direction damping gasket 6, and the damping effect of the steering wheel is controlled by adjusting the frictional force. This design ensures that the damping force of the steering wheel during rotation can be precisely adjusted as needed. Through the combination of the direction damping gasket 6 and the steering wheel damping friction sleeve 5, the damping adjustment of the steering wheel is made more flexible and controllable. Since these components are tightly connected to the transmission shaft 41 and the damping spring seat 1, the stability of the overall structure is guaranteed, further improving the accuracy and responsiveness of the steering wheel operation. In addition, this design can effectively reduce the vibration and abnormal noise of the steering wheel, improving the operating comfort and equipment reliability. The direction damping gasket 6 and the steering wheel damping friction sleeve 5 can be made of different materials, such as high-strength alloys, wear-resistant plastics or composite materials, to adapt to different working environments and requirements. At the same time, the thickness of the direction damping gasket 6 and the surface friction coefficient of the steering wheel damping friction sleeve 5 can be adjusted according to actual applications to achieve a more refined damping adjustment effect. In addition, the connection method of the transmission shaft 41 can also be modified to facilitate the replacement and maintenance of these key components.
[0032] The adjusting mechanism 7 includes an adjusting screw 71. The adjusting screw 71 is connected to the direction damping gasket 6 and the fixing sleeve 42. The core component of the adjusting mechanism 7 is the adjusting screw 71. By connecting the adjusting screw 71 to the direction damping gasket 6 and the fixing sleeve 42, the relative position between the direction damping gasket 6 and the fixing sleeve 42 can be adjusted. By rotating the adjusting screw 71, the operator can change the pressing degree of the direction damping gasket 6, thereby adjusting the frictional force between the steering wheel damping friction sleeve 5 and the direction damping gasket 6. This adjustment mechanism enables precise control of the damping force of the steering wheel to meet the requirements in different operating environments.
[0033] By setting the adjusting screw 71, the adjustment process of the steering wheel damping adjustment mechanism becomes more convenient and intuitive. The design of the adjusting screw 71 allows the operator to make precise damping force adjustments according to actual needs without disassembling or replacing other components, thus improving the operation efficiency and service life of the equipment. In addition, this adjustment mechanism enables the equipment to adapt to different operating environments and user preferences, enhancing the applicability of the equipment and the user experience.
[0034] The material and specifications of the adjusting screw 71 can be selected according to needs. For example, high-strength steel or corrosion-resistant materials can be used to improve durability and wear resistance. In addition, the structure of the adjusting screw 71 can also be designed to have a self-locking function to prevent loosening in a vibrating environment. The adjustment method can also be changed from a screw to other mechanical or electric adjustment devices, such as using a fine-tuning knob or an electric servo device, to achieve a more precise and automated adjustment function.
[0035] A steering wheel assembly 8 is fixedly connected to the top of the transmission shaft 41. By fixedly connecting the top of the transmission shaft 41 to the steering wheel assembly 8, the steering wheel assembly 8 can be stably mounted on the transmission shaft 41. When the operator turns the steering wheel, the steering wheel assembly 8 drives the transmission shaft 41 to rotate synchronously, thereby adjusting the frictional force between the steering wheel damping friction sleeve 5 and the direction damping gasket 6 through the transmission mechanism 4 to achieve the control of the steering wheel rotation damping. This design ensures a firm connection between the steering wheel assembly 8 and the transmission shaft 41, avoiding possible loosening or offset problems during operation.
[0036] By fixedly connecting the steering wheel assembly 8 to the transmission shaft 41, the stability and reliability of the steering wheel operation are ensured. This design not only enhances the response speed and operation accuracy of the steering wheel but also reduces the safety hazards caused by the loosening of the steering wheel. In addition, this fixed connection method makes the installation and maintenance of the steering wheel more convenient, enabling the quick replacement or repair of the steering wheel assembly 8 and reducing the maintenance cost of the equipment.
[0037] The connection method between the steering wheel assembly 8 and the transmission shaft 41 can adopt different fixing means, such as bolt connection, snap connection or keyway connection, to adapt to different installation requirements and steering wheel designs. At the same time, the design of the steering wheel assembly 8 can also be adjusted according to specific application scenarios. For example, a more ergonomic design or a steering wheel with an electronic control device can be used to enhance the user experience and operation comfort. In addition, the top connection structure of the transmission shaft 41 can be designed to be adjustable or detachable to facilitate the replacement or upgrade of the steering wheel assembly 8.
[0038] A steering wheel angle sensor assembly 9 is installed at the bottom of the damping spring seat 1. The steering wheel angle sensor assembly 9 is installed at the bottom of the damping spring seat 1 and is used to detect the rotation angle of the steering wheel in real time. When the operator turns the steering wheel, the rotation of the transmission shaft 41 transmits the angle change information to the control system through the steering wheel angle sensor assembly 9. The control system can perform corresponding control or adjustment according to the detected angle change, so as to realize the precise operation and control of the stacker. This design ensures that the rotation angle of the steering wheel can be monitored in real time, enhancing the automation level and operation safety of the equipment.
[0039] By installing the steering wheel angle sensor assembly 9 at the bottom of the damping spring seat 1, the precise monitoring and control of the steering wheel operation are realized. The application of this sensor assembly improves the operation accuracy of the stacker. Especially in a complex working environment, it can significantly reduce the human operation error, improve the work efficiency and safety. In addition, the integrated design of the sensor assembly makes the installation and maintenance of the system more convenient, which helps to extend the service life and reliability of the equipment.
[0040] The steering wheel angle sensor assembly 9 can select different types of sensors according to different application requirements, such as optical sensors, magnetic sensors or potentiometer sensors, to improve the detection accuracy and response speed. At the same time, the position of the sensor assembly can also be adjusted according to the specific equipment layout to adapt to different space limitations or installation requirements. In addition, the connection method between the sensor and the control system can be wired or wireless to meet different communication requirements and environmental requirements.
[0041] When this structure is installed and used, first fix the damping spring seat at an appropriate position in the cab to ensure firm installation. Press the metal damping disc on the damping spring seat through a small spring and fix it with a positioning pin to prevent rotation during the adjustment process. Connect the transmission main shaft and the fixed sleeve with a positioning pin and pass through the central hole of the damping spring seat. Sleeve the nylon damping friction sleeve and the metal damping pad onto the lower end of the transmission shaft to ensure that they can fit tightly. Connect and fix the metal damping pad with the threaded hole at the lower end of the fixed sleeve using an adjusting screw. Control the damping size by adjusting the tightness of the adjusting screw. Install the steering wheel on the transmission main shaft and ensure that the steering wheel and the transmission main shaft form a co-rotation relationship. Install the steering wheel angle sensor assembly and connect it to the control system. Debug the whole mechanism to ensure that the damping adjustment function is normal and the steering wheel turning torque is appropriate.
