Description

Technical Field

[0001] The present invention belongs to the technical field of support devices, and in particular relates to an adjustable support device and a support adjustment method. Background Art

[0002] Products need to be supported during transportation or storage, and long cylinders require multi-point support.

[0003] Current support systems are primarily categorized as rigid and flexible. Multi-point rigid supports can be difficult to fully guarantee due to factors such as the position, size, and assembly of the support system. In this scenario, two pairs of rigid supports can be used, with flexible supports at the remaining locations.

[0004] However, current flexible support devices are primarily used for cushioning, without requiring a specific support force. Therefore, when a product is statically parked, current flexible support devices may not provide specific support force, or may provide no support force at all. When a product is being transported, current flexible support mechanisms also cannot provide a specific support force range according to design requirements. Summary of the Invention

[0056] Example:

[0057] See also Figures 1 to 11 In one aspect, the present invention provides an adjustable support device in a preferred embodiment of the present invention, which includes a first support member 1, a force adjustment assembly 2, a first adjustment member 3, a second adjustment member 4, a first limit member 5 and a third adjustment member 6. Figure 1 and Figure 3 As shown, the first support member 1 can be a support plate. When the product has a cylindrical surface, the top surface of the first support member 1 can also be made into an arc surface to fit the cylindrical surface of the product, which can provide better support.

[0058] Specifically, if Figure 7 As shown, in a preferred embodiment, the force adjustment assembly 2 includes a first connecting member 201, an elastic member 202, and a second limiting member 203. The elastic member 202 is arranged around the first connecting member 201, and the first connecting member 201 is connected to the first adjusting member 3. The first support member 1 is placed on top of the first adjusting member 3, and the force adjustment assembly 2 is located between the first support member 1 and the first adjusting member 3. The second limiting member 203 is connected to one end of the first connecting member 201 to limit the elastic member 202.

[0059] In a specific implementation, the first connecting member 201 can be a shaft-shaped object, and the elastic member 202 can be a plurality of disc springs, which are wound around the outside of the shaft to generate force during the extrusion process to provide greater support force and adjustable support force. Figure 8As shown, a connecting groove can be provided on the first adjusting member 3 for the stress adjusting component 2, and at least a part of the force adjusting component 2 can be accommodated in the connecting groove. The end of the first connecting member 201 facing away from the connection to the first adjusting member 3 is connected to the second limiting member 203, and the second limiting member 203 can specifically use a retaining ring to prevent the elastic member 202 from detaching from the first connecting member 201 during the extrusion process. The end of the first connecting member 201 facing away from the connection to the first adjusting member 3 can be connected to a nut to connect well with the first support member 1, and the first support member 1 can be provided with a corresponding groove for connection. In a preferred embodiment, two force adjusting components 2 are provided, which can evenly support the first support member 1 and provide even supporting force. The number of force adjusting components 2 can be set according to actual conditions, and no excessive restrictions are imposed here.

[0060] Furthermore, if Figure 2 、 Figure 8 and Figure 9 As shown, in the preferred embodiment, the top surface of the second adjusting member 4 has a certain slope, and the bottom surface of the first adjusting member 3 is provided with a corresponding slope corresponding to the second adjusting member 4. The bottom surface of the first adjusting member 3 can be fitted with the top surface of the second adjusting member 4 and the first adjusting member 3 is placed on top of the second adjusting member 4.

[0061] It is understood that the first adjusting member 3 and the second adjusting member 4 can be configured as adjustment blocks, with the top surface of the second adjusting member 4 being sloped and the bottom surface of the first adjusting member 3 being sloped. The first adjusting member 3 and the second adjusting member 4 can move relative to each other in an inclined direction, i.e., the first adjusting member 3 and the second adjusting member 4 are cooperating wedge-shaped sliders. When the second adjusting member 4 is moved horizontally, the relative movement between the two can convert the horizontal movement into vertical movement, thereby varying the supporting force provided by the first support member 1 in the vertical direction.

[0062] Specifically, in a preferred embodiment, the third adjusting member 6 is adjustably connected to the second adjusting member 4, and the third adjusting member 6 can move the second adjusting member 4 along the first direction a. The first limiting member 5 is provided corresponding to the first adjusting member 3 and the second adjusting member 4, and is disposed outside the first adjusting member 3 and the second adjusting member 4 to limit the movement of the first adjusting member 3 in the first direction a and the second direction b, and the movement of the second adjusting member 4 in the second direction b.

[0063] In the preferred embodiment, the first direction a and the second direction b belong to the same plane, and the first direction a is perpendicular to the second direction b. Figure 10 and Figure 11 As shown, the first direction a and the second direction b belong to the horizontal direction.

[0064] It is understandable that if Figure 4As shown, the first limiting member 5 is a housing that can cover the first adjusting member 3 and the second adjusting member 4 while also acting as a limiter to improve stability during the support process. The third adjusting member 6 can optionally be a drive motor that is electrically connected to the second adjusting member 4 to drive the second adjusting member 4 to move along the first direction a.

[0065] In this preferred embodiment, if Figure 6 As shown, the third adjusting member 6 can be an adjusting screw, i.e., a thread is provided on the outer side of the third adjusting member 6. The second adjusting member 4 is correspondingly provided with a threaded hole, and the third adjusting member 6 is threadedly connected to the second adjusting member 4. The third adjusting member 6 is rotatably connected to the first limiting member 5. The first limiting member 5 limits the movement of the third adjusting member 6 in the first direction a. Rotation of the third adjusting member 6 enables the second adjusting member 4 to move along the first direction a.

[0066] It can be understood that the third adjusting member 6 is threadedly connected to the second adjusting member 4. When the third adjusting member 6 rotates, the third adjusting member 6 and the second adjusting member 4 will move relative to each other along the first direction a. Since only the second adjusting member 4 needs to move along the direction a during use, the freedom of the third adjusting member 6 is limited during setting so that it has only rotational freedom relative to the second limit member 203 and cannot move along the first direction a or the second direction b. In this way, the second adjusting member 4 can only move along the first direction a. In this way, the third adjusting member 6 can drive the second adjusting member 4 to move and thus drive the first adjusting member 3 to move, thereby converting the horizontal movement into the vertical movement, which can change the supporting force to make the support better.

[0067] More specifically, in a preferred embodiment, the third adjusting member 6 includes an operating portion 601, which is located at one end of the third adjusting member 6 near the threaded hole. It is understood that when in operation, the third adjusting member 6 mostly extends into the second adjusting member 4, with a small portion positioned outside the second adjusting member 4 to facilitate operation and rotation of the third adjusting member 6. A tool hole can be provided at this end to accommodate a tool for rotating the third adjusting member 6. Similarly, the operating portion 601 can be specifically implemented as a handle, making it easier for the operator to rotate the third adjusting member 6.

[0068] Furthermore, if Figure 5As shown, in a preferred embodiment, an adjustable support device further includes a second support assembly 7, and the first limiting member 5 is placed on the second support assembly 7. It can be understood that the second support assembly 7 is a support seat, and a fixed plate, i.e., an upper fixed plate 701, is provided on its top surface. The second support assembly 7 also includes a heightening member, and the heightening member is arranged around the second support assembly 7. The heightening member can be specifically set as a left and right heightening member 702 and a front and rear heightening member 703. The upper fixed plate 701, the left and right heightening members 702 and the front and rear heightening members 703 are all connected by welding. The upper fixed plate 701 can be used to connect the second adjustment member 4, and connecting parts are provided on both sides thereof, which can be used for connection and is convenient for operators to carry. The setting of the heightening member can be set according to actual conditions, which can make the device as a whole higher and adapt to a wider range of situations.

[0069] Preferably, in the preferred embodiment, the adjustable support device further includes a second connecting member 8, and the first limiting member 5 and the second support assembly 7 are fixedly connected via the second connecting member 8. In a specific implementation, the second connecting member 8 is a bolt, which passes through the through holes provided in the connecting portions on both sides of the upper fixing plate 701 and the corresponding connecting holes provided in the first limiting member 5, and is then fixed with a nut to ensure that the first limiting member 5 can be fixedly connected to the second support assembly 7.

[0070] More preferably, in the preferred embodiment, the second support assembly 7 further includes a fixed support plate 704 positioned at the bottom end of the height-raising member. In the preferred embodiment, the adjustable support device further includes a fixing member 705, which is used for securing the bottom end. In a specific implementation, two sets of fixing members 705, such as studs, can be provided to stabilize the height-raising member and provide a stable and effective support for the second support assembly 7.

[0071] In addition, in a preferred embodiment, a scale plate 101 is provided on the side of the first support member 1, and a pointer 301 is provided on the first adjustment member 3 corresponding to the scale plate 101. The displacement of the first support member 1 relative to the first adjustment member 3 in the third direction c can be displayed by the indication of the pointer 301 on the scale plate 101. The third direction c is perpendicular to the plane where the first direction a and the second direction b are located. That is, the plane where the first direction a and the second direction b are located is a horizontal plane, and the third direction c is a vertical direction. It can be understood that the scale plate 101 can be marked with scales according to actual conditions. In this way, the supporting force during support can be displayed by the position of the pointer 301 relative to the scale plate 101, so that the operator can understand the current size of the supporting force.

[0072] Another aspect of the present invention provides a method for adjusting support, which is implemented according to the adjustable support device described above and includes the following steps:

[0073] (1) Install and connect the two force adjustment components 2 on the first adjustment member 3, and install the first support member 1 on the force adjustment component 2. After the installation is completed, place the first adjustment member 3, the first support member 1 and the force adjustment component 2 on the second adjustment member 4.

[0074] (2) Place the first limiting member 5 on the outside of the first adjusting member 3 and the second adjusting member 4 to limit the displacement of the first adjusting member 3 in the first direction a and the second direction b and the movement of the second adjusting member 4 in the second direction b. Then, connect and fix the first limiting member 5 to the second support assembly 7, weld the upper fixing plate 701, the left and right height increasing members 702, and the front and rear height increasing members 703, and secure the fixed support plate 704 with the fixing member 705.

[0075] (3) Controlling the third adjusting member 6 causes the second adjusting member 4 to move along the first direction a, thereby driving the first adjusting member 3 and the first support member 1 to move in a direction perpendicular to the plane containing the first direction a and the second direction b. Specifically, rotating the third adjusting member 6 causes the second adjusting member 4 to move horizontally through the threaded connection, driving the first adjusting member 3 to slide along the inclined surface, and driving the force adjustment assembly 2 to move upward in the vertical direction, thereby driving the first support member 1 to move upward.

[0076] (4) If Figure 10 As shown, the third adjustment member 6 can be adjusted until the first support member 1 contacts the product support surface. If the support force needs to be adjusted, the third adjustment member 6 can be further adjusted until the required support force is achieved. When the first support member 1 contacts the product support surface, the third adjustment member 6 is further rotated, and the first support member 1 is restrained from further upward movement, thereby compressing the elastic member 202 to provide a flexible support force. The magnitude of the support force is determined by the display of the pointer 301 and the scale plate 101.

[0077] like Figure 11 As shown, after support is completed, the third adjustment member 6 is retracted until the first support member 1 separates from the product support surface. Specifically, the third adjustment member 6 is rotated to move the second adjustment member 4 backward, driving the first adjustment member 3 to slide along the inclined surface, driving the force adjustment assembly 2 downward, and thus driving the first support member 1 downward. The flexible support force of the compression elastic member 202 is first released until the first support member 1 separates from the product support surface.

[0078] The adjustable support device and method of the present invention are simple to operate, highly compatible, safe, and reliable. When the device is parked statically, it can provide a specific support force or no support force. During dynamic transport, the device can provide a specific support force range based on design requirements, providing controllable support for the product. It can be used in a variety of scenarios, is highly reliable, and has good use value and application prospects.

[0079] It will be easily understood by those skilled in the art that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
