Description

Technical Field

[0001] This utility model relates to the field of material carrying devices, and in particular to a roller device with strong load-bearing capacity. Background Technology

[0002] Idler rollers are an important component of belt conveyors. They come in many types and are numerous. They support the weight of the conveyor belt and materials. They account for 35% of the total cost of a belt conveyor and generate more than 70% of the resistance. Therefore, the quality of idler rollers is of paramount importance.

[0003] In existing technologies, when the idler roller device carries some heavy materials, the pressure and impact of the heavy objects can easily cause the surface of the idler roller to deform. The deformed idler roller will cause the bearing to rotate unevenly, subject the bearing to additional pressure, and affect the performance and service life of the bearing and other components. Furthermore, long-term friction with the conveyor belt or materials will cause wear on the roller surface, resulting in pits and grooves, and the load-bearing capacity of the idler roller will decrease. Therefore, an idler roller device with a strong load-bearing capacity is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a roller device with strong load-bearing capacity, aiming to improve the problems in the prior art that "affect the use effect and service life of the roller device. When the roller device carries some heavy materials, the pressure and impact of the heavy objects can easily cause the surface of the roller to deform. The deformed roller will cause the bearing to rotate unevenly and reduce the load-bearing capacity."

[0021] 1. In this utility model, by setting a support mesh frame inside the idler roller shell, the idler roller shell is made lighter while improving its resistance to deformation. Combined with the buffer adjustment component, the overall load-bearing capacity of the device can be effectively improved, further enhancing the device's performance.

[0022] 2.

The device is equipped with a cleat 43 for rotating the shaft 41. A buffer block 48 is slidably connected to the outer wall of the support rod 3. A sliding plate 49 for pushing other components to move upward and reset is fixedly connected to the right surface of the buffer block 48. A connecting frame 47 for mounting the auxiliary roller 410 is fixedly connected to the front surface of the buffer block 48. The auxiliary roller 410 is rotatably connected to the inner wall of the connecting frame 47. The auxiliary roller 410 is used to help the device lift the conveyor belt and prevent the conveyor belt from being squeezed and stuck between two adjacent idlers when conveying heavy objects. The sliding plate 49 and the support rod 3 are elastically connected by a spring 46. The spring 46 provides a buffering effect for the shaft 41. A mounting plate 44 for mounting the push block 45 is fixedly connected to the right surface of the sliding plate 49. The push block 45 is fixedly connected to the inner side of the mounting plate 44. The push block 45 is used to engage the cleat 43 to make the shaft 41 rotate slightly.

[0032] Reference Figure 1 , Figure 2 The bearing mechanism also includes a support assembly 2, which includes a bearing 25. The bearing 25 is an existing structure and is one of the main support components of the idler roller. The bearing 25 is installed on the outer wall of the shaft body 41. The outer wall of the bearing 25 is equipped with a mounting seat 24 for mounting the bearing 25. The outer wall of the mounting seat 24 is equipped with a sealing ring 26 for providing a seal for the bearing 25 in conjunction with the mounting seat 24. The outer wall of the mounting seat 24 is fitted with a sleeve 23 for mounting the support frame 22. The outer wall of the sleeve 23 is fixedly connected to the support frame 22 for improving the deformation resistance of the idler roller shell 21. The outer wall of the support frame 22 is provided with the idler roller shell 21. The mounting seat 24 is fixedly connected to the inner wall of the idler roller shell 21, and the mounting seat 24 fixes the idler roller shell 21. The sealing ring 26 is fitted on the outer wall of the shaft body 41. The support frame 22 is set in the shape of a hollow column with an internal hollow structure, which can enhance the deformation resistance of the idler roller shell 21 while reducing the weight of the idler roller device.

[0033] Reference Figure 3 , Figure 4 , Figure 5The sliding plate 49 is slidably connected to the inner wall of the support rod 3 and is pushed by the spring 46. The mounting plate 44 is slidably connected to the inner wall of the support rod 3 and pushes the pushing block 45 to the tooth 43 of the shaft 41. The connecting frame 47 is L-shaped and is used to install the auxiliary roller 410. Multiple sets of connecting frames 47 are provided, and the multiple sets of connecting frames 47 are symmetrically arranged with the center line of the shaft 41 as the axis of symmetry. The pushing block 45 is triangular prism in shape to reduce the scraping caused by the tooth 43 leaving. The tooth 43 is trapezoidal in shape, and the number of tooth 43 is multiple. The multiple sets of tooth 43 are arranged in a rotating array with the center line of the shaft 41 as the axis of rotation.

[0034] Working principle: When the conveyor belt is under heavy load, the longitudinal pressure is transmitted to the support frame 22 through the idler shell 21. The hollow column structure of the support frame 22 can maintain its anti-deformation ability and evenly distribute the load to the sleeve 23 and the mounting seat 24. At this time, the bearing 25 acts as the main load-bearing component and achieves stable rotation on the shaft 41. When the conveyor belt is subjected to impact load, the buffer adjustment component 4 starts the adaptive adjustment mechanism. The impact force is transmitted to the connecting frame 47 through the auxiliary roller 410, which drives the buffer block 48 to slide laterally along the support rod 3. At this time, the sliding plate 49 compresses the spring 46 to generate a reverse force. At the same time, the mounting plate 44 drives the triangular prism push block 45 to mesh with the trapezoidal tooth 43 of the shaft 41. Under the action of the inclined surface cooperation between the tooth 43 and the push block 45, the shaft 41 produces a small angular displacement, adjusting the bearing angle of the shaft 41 to ensure the performance of the shaft 41. The symmetrical arrangement of the auxiliary rollers 410 forms a three-point support structure, which can effectively prevent the conveyor belt from getting stuck in the gap of the idler rollers when heavy objects pass by. Combined with the radial support force of the support frame 22, the conveyor belt always maintains a stable running state.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
