Description

Technical field

[0001] The utility model relates to the technical field of building material processing equipment, in particular to a column lifting assembly. [Background Technology]

[0002] At present, some building materials need to be processed on multiple sides, such as refractory bricks. During the production process, milling is usually required to process the six sides of the bricks.

[0003] Specifically, when processing the side of a building material, a lifting mechanism is needed to drive the side milling mechanism to lift and lower it, so that the side milling mechanism can better contact the side of the building material to achieve processing. In the past, only one side milling mechanism was usually used to process the side of a building material, so the requirements for the lifting mechanism were relatively low; and the efficiency of processing with a single side milling mechanism was low. In order to improve the processing efficiency, the inventor of this case proposed a solution for processing the side of a building material using multiple side milling mechanisms. However, as the number of side milling mechanisms increases, higher requirements are placed on the stability and reliability of the lifting. The previous lifting mechanism can no longer meet the use requirements. Therefore, it is urgent to provide a lifting assembly that can drive multiple side milling mechanisms to lift and lower reliably and stably. [Utility Model Content]

[0036] See also Figures 1 to 6 As shown, the utility model provides a column lifting assembly 100, which includes a column body 1, a lifting beam 2, a lifting drive mechanism 3, and a lifting balancing mechanism 4. The column body 1 is used to support the lifting beam 2, the lifting beam 2 is used to install a side milling mechanism, the lifting drive mechanism 3 is used to drive the lifting beam 2 and the side milling mechanism installed on the lifting beam 2 to perform lifting movements together, and the lifting balancing mechanism 4 is used to balance the lifting beam 2.

[0037] Both ends of the lifting beam 2 are equipped with the column body 1, and each of the column bodies 1 is connected to the lifting beam 2 through a lifting drive mechanism 3, and the lifting beam 2 is driven to perform lifting movements by the lifting drive mechanism 3. During the specific implementation of the present invention, multiple side milling mechanisms are installed on the lifting beam 2. When the lifting drive mechanism 3 drives the lifting beam 2 to perform lifting movements, the multiple side milling mechanisms can be driven to move together; each of the column bodies 1 is provided with a lifting balancing mechanism 4 above the lifting beam 2, and the movable end of the lifting balancing mechanism 4 faces downward and is connected to the lifting beam 2, so that the lifting balancing mechanism 4 can be used to balance the two ends of the lifting beam 2.

[0038] The present invention sets a lifting drive mechanism 3 between the two ends of the lifting beam 2 and the column body 1, and at the same time, a lifting balancing mechanism 4 is also provided at both ends of the lifting beam 2. In specific operation, in addition to being able to use the lifting drive mechanism 3 to drive the lifting beam 2 to perform lifting movement, the lifting balancing mechanism 4 can also be used to balance the two ends of the lifting beam 2, thereby driving the lifting beam 2 and multiple side milling mechanisms installed on the lifting beam 2 to perform reliable and stable lifting and lowering, thereby ensuring the working stability of each side milling mechanism.

[0039] In some embodiments of the present invention, the lifting balancing mechanism 4 is a lifting balancing oil cylinder 41. The fixed end of the lifting balancing oil cylinder 41 is fixedly connected to the column body 1, and the movable end of the lifting balancing oil cylinder 41 is connected to the end of the lifting beam 2 via a pull seat 42. During the specific implementation of the present invention, the fixed end of the lifting balancing oil cylinder 41 can be locked to the column body 1 using screws or bolts, and the pull seat 42 can also be locked to the end of the lifting beam 2 using screws or bolts. The balancing oil cylinder is a hydraulic actuator that can achieve load balancing. It introduces a balancing oil circuit between the two chambers of the oil cylinder, so that the oil cylinder can automatically balance the load during operation and achieve a stable working state, thereby improving the stability and reliability of the system.

[0040] In some embodiments of the present invention, the lifting drive mechanisms 3 at both ends of the lifting beam 2 are connected via a synchronization shaft 5, so that both ends of the lifting beam 2 can perform lifting movements synchronously, thereby further improving working stability.

[0041] In some embodiments of the present invention, please refer to Figure 2 and Figure 4 As shown, the lifting drive mechanism 3 includes a lifting rack 31, a driving gear 32, a dual-axis output reducer 33, a lifting slide rail 34 and a lifting slider 35; wherein the dual-axis output reducer 33 is also connected to a drive motor 331, so that the drive motor 331 can provide the required power, and the dual-axis output reducer 33 can reduce the speed output by the drive motor 331;

[0042] The dual-axis output reducer 33 is arranged on the lifting beam 2, and one output end of the dual-axis output reducer 33 is connected to the driving gear 32 through a transmission shaft 36, and the other output end of the dual-axis output reducer 33 is connected to the synchronization shaft 5; the lifting rack 31 is arranged on the column body 1 along the vertical direction, and the driving gear 32 is engaged with the lifting rack 31; both sides of the end of the lifting beam 2 are slidably connected to the lifting slide rail 34 through the lifting slider 35, and the lifting slide rail 34 is arranged on the column body 1 along the vertical direction.

[0043] When the lifting drive mechanism 3 is working, the driving motor 331 drives the dual-axis output reducer 33 to work, and the dual-axis output reducer 33 drives the driving gear 32 to rotate through the transmission shaft 36. At the same time, the other output end of the dual-axis output reducer 33 is linked to the two lifting drive mechanisms 3 through the synchronization shaft 5 to work synchronously; because the lifting rack 31 is arranged on the column body 1 in the vertical direction, and the driving gear 32 is engaged with the lifting rack 31, therefore, when the driving gear 32 is rotating, it will drive the lifting beam 2 and the side milling mechanism installed on the lifting beam 2 to lift and lower, so as to facilitate the side milling mechanism to process the side of the building material.

[0044] As a specific embodiment of the present invention, the lifting rack 31 is a helical rack, and the driving gear 32 is a helical gear. By using the helical rack and the helical gear in combination, higher transmission efficiency and reduced energy loss can be achieved, while also having better adaptability and accuracy, and a longer service life.

[0045] Furthermore, the end of the lifting beam 2 is provided with a bearing seat 21, and the middle part of the transmission shaft 36 is connected to the bearing seat 21 through a bearing 22. The bearing seat 21 is also provided with a bearing seat cover 23 on the side facing the driving gear 32. This not only can well meet the support requirements of the transmission shaft 36 and enable the transmission shaft 36 to rotate, but also the setting of the bearing seat cover 23 can facilitate the assembly of the bearing 22 and ensure the stability of the bearing 22 after assembly.

[0046] In some embodiments of the present invention, please refer to Figure 5 As shown, the lifting beam 2 includes a main beam body 24 and a cover plate 25, which is installed on the top or bottom of the main beam body 24. A mounting cavity 241 is formed at each end of the main beam body 24, and the dual-axis output reducer 33 is disposed within the mounting cavity 241. By designing the lifting beam 2 to include the main beam body 24 and the cover plate 25 installed on the top or bottom of the main beam body 24, it is easier to install the dual-axis output reducer 33, the synchronous shaft 5, etc. into the lifting beam 2.

[0047] In some embodiments of the present invention, in order to facilitate the connection of the transmission shaft 36 and the synchronous shaft 5 with the dual-shaft output reducer 33, both output ends of the dual-shaft output reducer 33 are provided with couplings 37, and the transmission shaft 36 and the synchronous shaft 5 are connected to the couplings 37.

[0048] In some embodiments of the present invention, a mounting groove 11 is formed vertically in the middle portion of the column body 1 on the side facing the lifting beam 2, and the lifting and balancing mechanism 4 is disposed within the mounting groove 11. Providing the mounting groove 11 on the column body 1 and installing the lifting and balancing mechanism 4 within the mounting groove 11 not only protects the lifting and balancing mechanism 4, but also makes the entire column body 1 more compact, simple, and aesthetically pleasing.

[0049] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and are not intended to limit the scope of the present invention.
