[0025] Example 1

[0026] like Figure 1-4 As shown, this is the first embodiment of the present invention, which provides a rotary boom base, including...

[0027] The support assembly 100 includes a base 110, movable wheels 120 movably connected to the front and rear ends of both sides of the base 110, hydraulic cylinders 130 disposed around the base 110, a chassis 140 fixedly connected to the output end of the hydraulic cylinders 130, and a rotating assembly 200 disposed in the inner cavity of the base 110.

[0028] The connecting assembly 300 includes a connecting plate 310, a support column 320 fixedly connected to the top of the connecting plate 310, an arm column 330 disposed on the top of the support column 320, a locking rod 340 fixedly connected to the bottom of the arm column 330, and a threaded sleeve 350 threadedly connected to the surfaces of the support column 320 and the arm column 330.

[0029] like Figure 1-4As shown, the clamping rod 340 at the bottom of the boom column 330 extends into the inner cavity of the support column 320 and engages with it. Then, the threaded sleeve 350 is threadedly connected to the surface of the support column 320 and the boom column 330 for fixation, thus enabling quick installation without the need for precise alignment of the mounting holes and tightening multiple bolts one by one, greatly simplifying the installation steps. The support assembly 100 has movable wheels 120 connected to the front and rear ends of the base 110 on both sides. When displacement or transportation is required, the movable wheels 120 can roll on the ground to reduce resistance, thus easily pushing the boom seat to move without the need for multiple people to carry it, reducing the difficulty of operation. When the boom seat reaches the required position, the hydraulic cylinder 130 lowers the chassis 140, making the chassis 140 contact the ground, increasing the contact area with the ground, thereby achieving positioning and effectively improving the stability of positioning. The rotating assembly 200 can drive the connecting assembly 300 to rotate, thus enabling the boom to rotate in the horizontal direction to meet the needs of suspension operations in different directions.

[0030] Example 2

[0031] Reference Figure 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] In this embodiment, the rotating assembly 200 includes a drive gear 210 movably connected to the left side of the inner cavity of the base 110 via a bearing, a driven gear 220 movably connected to the right side of the inner cavity of the base 110 via a bearing, a transmission column 230 fixedly connected to the top of the driven gear 220, and a reduction motor 240 fixedly connected to the top of the base 110 and whose output shaft is drivenly connected to the left drive gear 210.

[0033] The bottom of the connecting plate 310 is movably connected to the top of the base 110 via a bearing, and the top of the transmission column 230 is fixedly connected to the bottom of the connecting plate 310. The driving gear 210 and the driven gear 220 mesh with each other. The bottom of the locking rod 340 extends into the inner cavity of the support column 320 and engages with the inner cavity of the support column 320.

[0034] The surface of the lever 340 is fixedly connected to a limiting strip 341, and the inner cavity of the support column 320 is provided with a limiting groove 321. The limiting strip 341 is located in the inner cavity of the limiting groove 321 and is movably connected to the inner cavity of the limiting groove 321.

[0035] like Figure 1-3As shown, a geared motor 240 is fixedly connected to the top of the base 110. Its output shaft is connected to the drive gear 210 on the left side. When the geared motor 240 starts, the output shaft drives the drive gear 210 to rotate. The drive gear 210 is movably connected to the left side of the inner cavity of the base 110 through a bearing, allowing it to rotate stably within the inner cavity of the base 110. The driven gear 220 is movably connected to the right side of the inner cavity of the base 110 through a bearing, meshing with the drive gear 210. When the drive gear 210 rotates, it drives the driven gear 220 to rotate through gear meshing. The transmission column 230 is fixedly connected to the driven gear. At the top of 220, when the driven gear 220 rotates, the transmission column 230 rotates synchronously, which facilitates the rotation of the connecting plate 310. The bottom of the locking rod 340 extends to the inner cavity of the support column 320 and engages with the inner cavity of the support column 320. This engagement method enables a stable connection between the arm column 330 and the support column 320. During the engagement process, the limiting strip 341 enters the limiting groove 321, which plays a guiding role, allowing the locking rod 340 to accurately and smoothly enter the inner cavity of the support column 320, and restricting the rotation of the locking rod 340 in the inner cavity of the support column 320, further enhancing the stability of the engagement.

[0036] Example 3

[0037] Reference Figure 1 , 2 4 and 5 are the third embodiment of this utility model, which is based on the first two embodiments.

[0038] In this embodiment, a bracket 131 is fixedly connected to the surface of the hydraulic cylinder 130, one side of the bracket 131 is fixedly connected to the base 110, and a positioning hole 141 is provided on the top of the chassis 140.

[0039] A tool slot 111 is provided on one side of the top of the base 110, and a baffle plate is fixedly connected to the inner cavity of the tool slot 111.

[0040] A cover 112 is hinged to one side of the top of the base 110 and above the tool slot 111. A sealing strip is fixedly connected to the surface of the cover 112, and one side of the sealing strip contacts the inner wall of the tool slot 111.

[0041] like Figure 1 , 2As shown in Figure 4, the bracket 131 fixed to the surface of the hydraulic cylinder 130 is fixedly connected to the base 110, thus providing a stable support for the hydraulic cylinder 130 and enabling it to operate stably during operation. This ensures the accuracy and reliability of the lifting action of the chassis 140. Through the positioning hole 141 on the top of the chassis 140, when the rotating boom is fixed in a specific position, bolts, ground nails, or other fasteners can be used to tightly connect the chassis 140 to the ground or other support platform, further enhancing the stability of the boom during operation and preventing it from collapsing due to external forces. The tool slot 111 is fixedly connected to a baffle plate inside its cavity to prevent movement caused by the impact of hoisting or wind. The baffle plate divides the internal space of the tool slot 111 into categories, allowing for the categorized storage of different types of tools. The sealing cover 112 can close the tool slot 111 when tools are not in use, preventing dust, debris, and moisture from entering the tool slot 111 and keeping the tools and parts clean and dry. At the same time, one side of the sealing strip contacts the inner wall of the tool slot 111, further enhancing the sealing effect and ensuring the airtightness of the internal environment of the tool slot 111, providing a good storage environment for tools and parts.

[0042] In use, first insert the locking rod 340 at the bottom of the boom column 330 into the inner cavity of the support column 320. The limiting strip 341 on the surface of the locking rod 340 enters the limiting groove 321 in the inner cavity of the support column 320, serving as a guide and locking mechanism. Then, threaded sleeve 350 is threaded onto the surfaces of the support column 320 and the boom column 330, ensuring a tight connection between them. This completes the installation of the boom. The entire process eliminates the need for precise alignment of mounting holes and individual tightening of multiple bolts, greatly simplifying the installation steps, saving significant time and manpower, and improving installation efficiency. When the boom needs to be rotated during use, the geared motor 240 is started, and its output shaft drives the drive gear 210 to rotate. The drive gear 210, through meshing with the driven gear 220, causes the driven gear 220 to rotate. When the driven gear 220 is moved, the transmission column 230 at the top of the driven gear 220 rotates accordingly. The top of the transmission column 230 is fixed to the connecting plate 310 in the connecting assembly 300, thereby driving the connecting assembly 300 and the boom to rotate, meeting the needs of suspension operations in different directions. When it is necessary to move the rotating boom seat, the hydraulic cylinder 130 retracts, raising the chassis 140 so that the moving wheel 120 contacts the ground. At this time, the moving wheel 120 can be used to easily push the boom seat for displacement adjustment or transportation. When the boom seat reaches the required position, the hydraulic cylinder 130 extends, lowering the chassis 140 so that the chassis 140 contacts the ground, increasing the contact area with the ground, improving the overall stability, and ensuring the safe operation of subsequent lifting operations. No multiple people are required to carry the load throughout the process, reducing the complexity and difficulty of the operation and reducing manpower input.

The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0044] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
