Description

TECHNICAL FIELD

[0001] The present application relates to the field of printing technology, in particular to a support device for large equipment. BACKGROUND

They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting this application. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0053] See also Figures 1-10 , an exemplary large equipment support device of the present application includes a support frame 10, a first lifting assembly 30, a second lifting assembly 40, and a top frame 20;

[0054] The first lifting assembly 30 is placed vertically, and four first lifting assemblies 30 are respectively installed at four locations of the supporting frame 10;

[0055] The second lifting assembly 40 is vertically arranged and installed at a position of the supporting frame 10;

[0056] The top frame 20 is respectively installed on the top of the first lifting assembly 30 and the top of the second lifting assembly 40;

[0057] The four first lifting assemblies 30 are connected by a synchronous belt and drive synchronously;

[0058] The second lifting assembly 40 is connected to a code disc.

[0059] The support device for large-scale equipment described in this application offers improved support stability compared to existing technologies. First, it provides a first lifting assembly 30 and a second lifting assembly 40, both of which can move independently of each other, thereby enabling diverse installation options. Furthermore, the second lifting assembly 40, acting as an extension of the first lifting assembly 30, provides more support points, allowing for application in larger equipment. Furthermore, existing support devices can be directly used as the first lifting assembly 30, thus ensuring the continued applicability of existing technologies.

[0060] In some preferred embodiments, two second lifting assemblies 40 are included, and the two second lifting assemblies are respectively installed at two locations on the support frame 10, such as Figure 7-10 shown.

[0061] In some embodiments, a second lifting assembly is provided, such as Figure 4-Figure 6 In other embodiments, there are two second lifting assemblies, such as Figure 7-10 As shown in the figure. The different number of lifting components means different support effects and directions. Figure 6 In the embodiment shown, the second lifting assembly is mounted in the middle of the bracket, and Figure 4 and Figure 5 In the embodiment shown, the second lifting assembly is installed at the corner of the bracket, and its technical effect is slightly different, mainly reflected in the support and transmission.

[0062] In some preferred embodiments, two of the first lifting assemblies 30 and one of the second lifting assemblies 40 are located on the same straight line; another two of the first lifting assemblies 30 and another of the second lifting assemblies 40 are located on another straight line.

[0063] In this embodiment, it is described as follows Figure 7-10Any technical solution of , wherein three lifting assemblies are located on a straight line, and the other three lifting assemblies are located on another straight line, and the two straight lines are parallel.

[0064] Even these six lifting components and the transmission synchronous belt form a rectangular cross-section.

[0065] In some preferred embodiments, Figure 4 、 Figure 7 or Figure 10 As shown, the synchronous belt passes through the four first lifting assemblies 30 in sequence;

[0066] Alternatively, in other preferred embodiments, Figure 5 、 Figure 6 or Figure 8 As shown, the synchronous belt sequentially passes around the four first lifting assemblies 30 and one of the second lifting assemblies 40;

[0067] Or, in some further preferred embodiments, as Figure 9 As shown, the synchronous belt passes around four first lifting assemblies 30 and two second lifting assemblies 40 in sequence.

[0068] It should be noted that there are two ways to install the code disc: one is to connect all lifting components to the code disc, and the other is to connect the code disc only to the lifting components that are not connected to the synchronous belt. In the first installation method, each code disc reads the number of rotations of a lifting component and achieves synchronous lifting while ensuring synchronous rotation. In the second installation method, some lifting components are driven by synchronous belts, and the code disc is installed on the remaining lifting components. Through the adaptation of the control program, the rotation synchronization of all lifting components is achieved.

[0069] In some preferred embodiments, a controller and a synchronous driver 50 are further included;

[0070] The synchronous driver 50 is connected to the synchronous belt and drives the synchronous belt to rotate;

[0071] The synchronous driver 50 and the code wheel are electrically connected to the controller respectively.

[0072] In some preferred embodiments, the synchronous drive 50 and the lifting drive are servo motors respectively.

[0073] In some preferred embodiments, the controller is a PLC module.

[0074] In some preferred embodiments, a lifting driver (not shown) is further included. The lifting driver is installed on the supporting frame 10 and is rotatably connected to the second lifting assembly 40 to drive the second lifting assembly 40 to rotate.

[0075] In such Figure 4 、 Figure 7 、 Figure 8 、 Figure 10 In the embodiment shown, when the second lifting assembly is not connected to the synchronous belt, the second lifting assembly is driven by the lifting driver, thereby achieving independent rotation compared to the synchronous belt. In order to ensure the rotation synchronization of the second lifting assembly and other lifting assemblies, it is achieved through program control of the controller. The principle is to measure the stroke of the lifting assembly in the linear speed direction through an encoder (or code disk), and then calculate the rotational linear speed of the lifting assembly. By controlling the running speed of the synchronous driver, the movement speed of the synchronous belt is controlled, and the movement speed of the lifting driver is controlled at the same time, so as to achieve the consistency of the movement linear speed of all lifting assemblies, thereby achieving the movement synchronization of all lifting assemblies and achieving smooth lifting of the entire top frame.

[0076] Regarding how to achieve coordination of the motion speeds of the synchronous drive, lift drive, and timing belt, this is a technical solution that can be achieved in the prior art, and is illustrated here with only one example. For example, the synchronous drive drives the timing belt through a speed reducer, with a speed ratio of 1:10. In this example, the lift drive drives the second lift assembly through gears, and the speed ratio of the gears transmitted to the second lift assembly is 5:1. To ensure the linear speed of all lift assemblies is consistent, the speed of the synchronous drive is twice that of the lift drive. At this point, the angular velocity of all lift assemblies is the same. Since all lift assemblies have the same structure and size, the linear velocity of all lift assemblies is also the same.

[0077] The above is an exemplary description of one feasibility, and this can be achieved with existing technology. The effect of all lifting components rotating at the same angular velocity can also be achieved through other existing methods, which will not be described in detail here.

[0078] The main purpose of providing a lifting drive is to drive the independent rotation of the second lifting assembly to ensure that all lifting assemblies rotate synchronously and at the same angular velocity. Therefore, there are two assembly relationships. The first is that each second lifting assembly is installed with a lifting drive; the second is that the lifting drive is only installed on the second lifting assembly that is not connected to the synchronous belt. In the first installation method, even if the second lifting assembly is driven and rotated by the synchronous belt, the lifting drive does not work and is in a passive rotation state. Of course, it is also possible to remove the passively rotating lifting drive or separate the passively rotating lifting drive from the second lifting assembly to save energy.

[0079] In some preferred embodiments, the first lifting assembly 30 includes a mounting plate 31, a rotating shaft 32, an upper bearing seat 34, a lower bearing seat 35, a supporting plate 36, and a sleeve 33;

[0080] The sleeve 33 is sleeved on the rotating shaft 32 and is located at the lower half of the rotating shaft 32;

[0081] The upper bearing seat 34 and the lower bearing seat 35 are respectively rotatably sleeved on the rotating shaft 32, and the sleeve 33 is located between the upper bearing seat 34 and the lower bearing seat 35;

[0082] The upper bearing seat 34 and the lower bearing seat 35 are respectively mounted on the mounting plate 31;

[0083] The outer wall of the upper half of the rotating shaft 32 is formed with spiral patterns;

[0084] A threaded hole is formed in the middle of the supporting plate 36, and the supporting plate 36 is sleeved on the rotating shaft 32 and is threadedly connected to the rotating shaft 32;

[0085] The mounting plate 31 is mounted on the supporting frame 10 , the supporting plate 36 is mounted on the top frame 20 , and the sleeve 33 is connected to the synchronous belt.

[0086] An accordion cover 37 is sleeved outside the spiral pattern and located between the upper bearing seat 34 and the supporting plate 36 . The accordion cover 37 is used to cover the external thread of the rotating shaft 32 .

[0087] In the present application, the upper bearing seat 34 serves to limit the rotation shaft 32. A bearing is disposed within the upper bearing seat 34, while a bearing is disposed within the lower bearing seat 35. The bearing is used to assemble and connect with the rotation shaft 32. The outer walls of the portions of the rotation shaft 32 located above and below the upper bearing seat 34 are formed with the aforementioned spiral pattern, which is connected to the internal thread of the support plate.

[0088] In some preferred embodiments, the first lifting assembly 30 further includes an encoder 38 , which is mounted on the mounting plate 31 and sleeved on the rotating shaft 32 .

[0089] The encoder and the code disc have the same structure and are both used to measure the angular displacement or angular velocity of the lifting component.

[0090] In these embodiments, each lifting assembly connected to the synchronous belt is connected to an encoder. If the second lifting assembly is not driven by the synchronous belt, a code disk is connected to the second lifting assembly. The code disk and the encoder are identical in structure, but are described with different names to reflect that they are connected to the second lifting assembly, even if the second lifting assembly is not connected to the synchronous belt.

[0091] In some preferred embodiments, the encoder 38 is electrically connected to the controller.

[0092] In some preferred embodiments, the first lifting assembly 30 further includes a bearing (not shown in the figure), which is tightly sleeved on the rotating shaft 32;

[0093] The upper bearing seat 34 and the lower bearing seat 35 are respectively rotatably sleeved with the T-shaped bearing.

[0094] In some preferred embodiments, the second lifting assembly 40 has the same structure as the first lifting assembly 30 .

[0095] The working principle of the supporting device of the exemplary large equipment of this application is as follows:

[0096] See also Figures 4-10 , the present application provides a variety of combined working modes of the first lifting assembly 30 and the second lifting assembly 40.

[0097] like Figure 4 First, four first lifting assemblies 30 and one second lifting assembly 40 are configured. The synchronous belt drives the four first lifting assemblies 30 to rotate synchronously, and the second lifting assembly 40 is independently driven by the lifting driver.

[0098] like Figure 5 Secondly, four first lifting assemblies 30 and one second lifting assembly 40 are configured, and the synchronous belt drives the four first lifting assemblies 30 and one second lifting assembly 40 to rotate synchronously at the same time.

The synchronous belt drives the four first lifting assemblies 30 to rotate synchronously, and the two second lifting assemblies 40 are independently driven to move by their own lifting drivers.

[0101] like Figure 8 Fifth, four first lifting assemblies 30 and two second lifting assemblies 40 are configured. The synchronous belt drives the four first lifting assemblies 30 and one second lifting assembly 40 to rotate synchronously at the same time, and the other second lifting assembly 40 is driven by the lifting driver.

[0102] like Figure 9 Sixth, four first lifting assemblies 30 and two second lifting assemblies 40 are configured, and the synchronous belt drives the four first lifting assemblies 30 and the two second lifting assemblies 40 to rotate synchronously at the same time.

[0103] like Figure 10Seventh, four first lifting assemblies 30 and two second lifting assemblies 40 are configured. The synchronous belt drives the four first lifting assemblies 30 to rotate synchronously, and the two second lifting assemblies 40 are synchronously driven by the synchronous belt and share a lifting drive.

[0104] In addition, in Figure 4-Figure 6 The solutions shown only express some ways of setting up a second lifting assembly. Figure 4 The transmission mode, Figure 6 The lifting assembly is arranged in such a way that the four first lifting assemblies are driven by synchronous belts, and the second lifting assembly is installed in the middle and driven independently.
