[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show preferred embodiments of the present invention.

[0025] like Figure 1 and Figure 2As shown, a machine body moving lifting device 10 is used to connect a frame, which includes a rotating assembly 100, a lifting assembly 200 and a traveling assembly 300. The rotating assembly 100 includes a lower support frame 110, an upper support frame 120 and a rotating driving member 130. The lower support frame 110 is coaxially rotatably arranged at the bottom end of the upper support frame 120. The rotating driving member 130 is arranged in the upper support frame 120, and the output shaft of the rotating driving member 130 is connected to the lower support frame 110. The lifting assembly 200 includes a lifting driving member 210 and a lifting seat 220, the lifting drive member 210 is arranged in the upper support frame 120, the lifting seat 220 is slidably arranged on the outer wall of the upper support frame 120, and the lifting seat 220 is connected to the output shaft of the lifting drive member 210, and the lifting seat 220 is connected to the frame, the travel component 300 includes a travel drive member 310 and a roller 320, the travel drive member 310 is arranged on the outer wall of the lower support frame 110, the roller 320 is rotatably arranged on the lower support frame 110, and the roller 320 is connected to the output shaft of the travel drive member 310.

[0026] Specifically, the lower support frame 110 and the upper support frame 120 are structures that can rotate with each other, and the lower support frame 110 is located below the upper support frame 120. The rotating drive member 130 is installed in the upper support frame 120, and the output shaft of the rotating drive member 130 is fixedly connected to the lower support frame 110, so that the rotating drive member 130 drives the lower support frame 110 to rotate relative to the upper support frame 120. In one embodiment, the rotating drive member 130 is a motor. Further, the lifting drive member 210 is installed in the upper support frame 120, and in one embodiment, the lifting drive member 210 is an electric cylinder. The lifting seat 220 is slidably installed on a side wall of the upper support frame 120, and the lifting seat 220 is connected to the output shaft of the lifting drive member 210, and the lifting seat 220 is used to be fixedly installed with the frame. In this way, the lifting seat 220 is driven by the lifting drive member 210 to perform lifting and lowering movements, so that the frame can be lifted and lowered relative to the ground. Furthermore, the roller 320 is rotatably mounted on the bottom of the lower support frame 110, the travel drive member 310 is mounted on the outer side wall of the lower support frame 110, and the output shaft of the travel drive member 310 is fixedly connected to the lower support frame 110, so that the travel drive member 310 drives the roller 320 to rotate, and the frame can move forward and backward. In this way, the lifting drive member 210, the rotating drive member 130, and the travel drive member 310 cooperate to drive the frame mounted on the lifting seat 220 to move forward and backward, lift, and turn, so that it can adapt to different terrain conditions and is more convenient to use.

[0027] like Figure 2 As shown, in one embodiment, the rotating assembly 100 further includes a thrust ball bearing 140 , and the thrust ball bearing 140 is connected to the upper support frame 120 and the lower support frame 110 , respectively.

[0028] It should be noted that since the lower support frame 110 and the upper support frame 120 need to support the frame together, and the frame often has a certain weight, in order to improve the structural strength between the upper support frame 120 and the lower support frame 110, a thrust ball bearing 140 is installed between the upper support frame 120 and the lower support frame 110 to effectively improve the supporting strength of the lower support frame 110 on the upper support frame 120.

[0029] like Figure 1 As shown, in one embodiment, the rotating assembly 100 further includes a ball bearing 150 , which is disposed on one end of the upper support frame 120 close to the lower support frame 110 , so that the output shaft of the rotating driving member 130 passes through the ball bearing 150 .

[0030] Specifically, the ball bearing 150 and the rotary drive member 130 are coaxially mounted, the ball bearing 150 is fixedly mounted in the upper support frame 120, and the output shaft of the rotary drive member 130 is fixedly mounted on the lower support frame 110 after the output shaft of the rotary drive member 130 passes through the ball bearing 150. In this way, the structural strength and stability of the output shaft of the rotary drive member 130 can be improved.

[0031] like Figure 1 As shown, in one embodiment, the machine body moving lifting device 10 also includes a support assembly 400, the support assembly 400 includes an L-shaped seat 410, a support driving member 420 and a support plate 430, the L-shaped seat 410 is arranged on the outer wall of the upper support frame 120, the support driving member 420 is arranged on the L-shaped seat 410, and the output shaft of the support driving member 420 is arranged downward along the vertical direction, and the support plate 430 is arranged on the output shaft of the support driving member 420.

[0032] Specifically, the L-shaped seat 410 is fixedly mounted on the upper support frame 120 by screws, and the support driving member 420 is mounted on the L-shaped seat 410, and the support driving member 420 is arranged downward. In one embodiment, the support driving member 420 is an electric cylinder, and the support plate 430 is mounted on the output shaft of the support driving member 420. In this way, the support driving member 420 drives the support plate 430 to rise and fall. When the support plate 430 descends to contact the ground, as the output shaft of the support driving member 420 drives the support plate 430 to descend, the roller 320 will rise and leave the ground. At this time, the frame is supported by the support plate 430 instead of the roller 320, so that the frame can operate stably, avoid moving forward and backward, and effectively improve the stability of the frame.

[0033] like Figure 1 As shown, in one embodiment, a slide groove 121 is provided on the outer wall of the upper support frame 120 along the axial direction, and the lifting seat 220 is slidably arranged in the slide groove 121. For example, the lifting seat 220 and the slide groove 121 are adapted to be installed, so that the lifting seat 220 can stably lift and slide relative to the upper support frame 120.

[0034] like Figure 2 As shown, in one embodiment, the travel driving component 310 includes a travel motor 311, a driving gear 312 and a driven gear 313. The travel motor 311 is arranged on the outer wall of the lower support frame 110, the driving gear 312 is arranged on the output shaft of the travel motor 311, and the driven gear 313 is coaxially arranged at one end of the roller 320, and the driven gear 313 is meshed with the driving gear 312.

[0035] Specifically, the travel motor 311 is fixedly mounted on the outer wall of the lower support frame 110 by screws, the driving gear 312 is fixedly mounted on the output shaft of the travel motor 311, the driven gear 313 is coaxially mounted with the roller 320, and the driven gear 313 is meshed with the driving gear 312. In this way, the travel motor 311 drives the driving gear 312 to rotate, and then drives the driven gear 313 to rotate, and finally drives the roller 320 to rotate forward or reverse, so that the frame can move forward or backward. It should be noted that the power transmission can be achieved by directly meshing the driving gear 312 with the driven gear 313, which can improve the power transmission efficiency. In one embodiment, the driving gear 312 and the driven gear 313 are both bevel gears.

[0036] like Figure 1 As shown, in one embodiment, the traveling assembly 300 further includes a protective cover 330 , which is buckled on one side of the lower support frame 110 , and the traveling driving component 310 is located in the protective cover 330 .

[0037] Specifically, in order to prevent dust from adhering to the travel motor 311 , the driving gear 312 , the driven gear 313 , etc., a protective cover 330 is installed on the outer wall of the lower support frame 110 using screws, and the travel motor 311 , the driving gear 312 , and the driven gear 313 are all located inside the protective cover 330 .

[0038] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
