[0002] In the roller shaft transportation process, the fixed device is used to fix the roller shaft during transportation, and the fixed device generally has a clamp and a binding belt. The clamp mainly fixes the roller shaft on the transportation equipment by mechanical clamping, and cooperates with the corresponding rubber pad and spring shock absorber to complete the shock absorption of the fixed device.

[0003] However, the clamping force control is complex. The clamping force of the clamp needs to be adjusted according to the size, material and transportation conditions of the roller shaft. If the clamping force is too large, it may cause indentation or damage to the surface of the roller shaft. If the clamping force is too small, the roller shaft cannot be effectively fixed, resulting in the roller shaft shaking or even falling off during transportation, especially in the axial movement process of the roller shaft. The clamp needs to generate greater friction with the roller shaft to fix the roller shaft.

[0004] To solve the above problems, an auxiliary device for roller shaft transportation is provided. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present application are described below with reference to the accompanying drawings, and it should be understood that the preferred embodiments described herein are intended to illustrate and explain the present application, and are not intended to limit the present application.

[0024] The same reference numerals in the drawings refer to the same components throughout.

[0025] Example 1

[0026] As Figures 1-3 shown, the present application provides an auxiliary device for roller shaft transportation, which comprises a device main body 1 and a shaft body 101, the device main body 1 comprises a long plate 2, a movable plate 3 and a fixed plate 4, the long plate 2 is provided with the fixed plate 4 at one end, the other end of the long plate 2 is hingedly connected with the movable plate 3, a support assembly 5 is arranged between the fixed plate 4 and the movable plate 3, the support assembly 5 is used for supporting the middle part of the shaft body 101, a first through hole 301 is arranged in the middle part of the movable plate 3, a second through hole 401 is arranged in the middle part of the fixed plate 4, a mounting ring 302 is arranged on the outer surface of the first through hole 301, the shaft body 101 is respectively penetrated through the first through hole 301 and the second through hole 401 at both ends, and the first through hole 301 and the second through hole 401 are used for extruding and fixing at both ends of the shaft body 101; after the shaft body 101 is penetrated through the first through hole 301 and the second through hole 401 at both ends and buckled to the long plate 2 through the hingedly connected movable plate 3, a fixed effect is formed based on both ends of the first through hole 301 and the second through hole 401, an axial limiting action is formed on the shaft body 101 itself, and when a clamping device or a binding belt is used, a better overall limiting effect can be assisted.

[0027] A rotating shaft 201 is arranged between the movable plate 3 and the long plate 2, a through screw 202 is arranged on the rear side of the long plate 2, and the through screw 202 is threadedly connected to the movable plate 3; as Figure 2 shown, after the reserved grooves of the movable plate 3 and the long plate 2 are buckled, the long plate 2 and the movable plate 3 can be further threadedly fixed through the through screw 202.

[0028] The inner side of the mounting ring 302 is provided with a telescopic spring 303, and the telescopic spring 303 is internally provided with a telescopic ring 304. The mounting ring 302 and the first through hole 301 are embeddedly mounted on the outer side edge, and the telescopic ring 304 is located inside the first through hole 301. After the shaft body 101 is placed on the right side of the second through hole 401 by embeddedly lapping, the shaft body 101 is inserted into the first through hole 301 on the left side to press the telescopic ring 304. The greater elastic strength of the telescopic spring 303 can form a buffer type fixation on the left side of the shaft body 101. When the shaft body 101 has axial displacement, the elasticity of the telescopic spring 303 is first resisted, thereby assisting the clamp to avoid displacement caused by axial inertia.

[0029] The first through hole 301 is provided with a limiting ring 305 on the inner wall close to the shaft body 101. The limiting ring 305 is used for limiting the telescopic length of the telescopic ring 304. Because the telescopic spring 303 and the telescopic ring 304 are limited by the limiting ring 305, the telescopic spring 303 has a certain elastic strength when the shaft body 101 is inside the first through hole 301.

[0030] The second through hole 401 is axially corresponding to the first through hole 301, and is used for lapping the end of the shaft body 101.

[0031] Specifically, the device body 1 can include a clamp, which can be installed on the long plate 2 to form a main fixation of the shaft body 101. The support assembly 5 is mainly installed on the fixed plate 4. When the shaft body 101 is placed, it is first inserted into the inside of the first through hole 301 and placed on the support assembly 5. Then, the movable plate 3 is rotated along the rotating shaft 201 until the first through hole 301 presses the other end of the shaft body 101. Finally, the through screw 202 is screwed from the rear surface of the long plate 2 to complete the installation. The first through hole 301 and the second through hole 401 form an auxiliary fixation.

[0032] When the shaft body 101 has an axial force, the telescopic spring 303 inside the first through hole 301 provides a counterforce, so that the shaft body 101 can provide a pressing force in the axial direction, and the second through hole 401 on the right side constitutes a clamping action. Even when the shaft body 101 itself slides slightly in the axial direction, the telescopic spring 303 with the elastic force of the limiting ring 305 can continuously push the shaft body 101 to the right, thereby forming a fixation of the shaft body 101 in the axial direction.

[0033] Embodiment 2

[0034] The difference from embodiment 1 is that, as Figure 4As shown, the upper surface edges of the long plate 2, the movable plate 3 and the fixed plate 4 are provided with raised strips 6, and the lower surface of the long plate 2, the movable plate 3 and the fixed plate 4 are provided with recessed grooves 7 corresponding to the shape of the raised strips 6. The two ends of the support component 5 include end heads 501, and connectors 502 are installed on the inner side of the end heads 501. A column 503 is installed on the upper surface of the connector 502, and an arc-shaped support 504 is provided at the top of both the end heads 501 and the column 503.

[0035] The top of the movable plate 3 and the fixed plate 4 are provided with an overlapping horizontal plate 601 inside the protrusion 6, and the vertical projection of the overlapping horizontal plate 601 covers the vertical projection of the end 501.

[0036] Specifically, such as Figure 4 As shown, when the main body 1 of the device is overlapped, it can be used with the support component 5 and the overlapping horizontal plate 601 to form a force transmission. The force in the middle of the shaft 101 will be transmitted to the connector 502 through the main body 503. The connector 502, through the connection between the end 501 and the overlapping horizontal plate 601, will transmit the force to the movable plate 3 and the fixed plate 4 on the bottom side until the force is transmitted to the ground, thereby increasing the stability of the main body 1 of the device when it is overlapped.

[0037] Even during transportation, the upper and lower main body 1 can be installed vertically through the connector, so that the connector forms a lateral limit, and the force transmission structure of the support component 5 allows the force in the middle of the shaft 101 to be transmitted to the bottom.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
