[0038] Reference Figure 1-3 , an embodiment of the utility model provides a trolley, comprising a bottom plate 2, a retractable lifting column 3, a frame body 1, a height-increasing cushion 5 and a universal wheel 4;

[0039] The frame body 1 is installed above the bottom plate 2, the lifting column 3 is installed at the bottom of the frame body 1, and the bottom plate 2 is provided with a through hole 21 for the lifting column 3 to pass through;

[0040] A plurality of universal wheels 4 are installed below the bottom plate 2; after the lifting column 3 is extended, the universal wheels 4 are away from the ground;

[0041] The height-increasing pad 5 is also provided between the frame body 1 and the bottom plate 2 to enable the lifting column 3 to be away from the ground after being retracted.

[0042] In this embodiment, the frame body 1 of the trolley is located above the base plate 2. The lifting column 3 and the universal wheel 4 are respectively arranged on two different planes of the frame body 1 and the base plate 2, and the frame body 1 is raised with a height-increasing pad 5 to overcome the height difference between the lifting column 3 and the universal wheel 4, so that the retracted lifting column 3 is away from the ground, and the universal wheel 4 moves on the ground to make the trolley move; when the lifting column 3 is stretched, the lifting column 3 touches the ground to support the trolley and share the pressure on the universal wheel 4, so that the trolley is fixed; in this way, the stability of the trolley in a fixed state can be ensured, and flexibility can be provided when it needs to be moved; secondly, the lifting column 3 is installed on the frame body 1 and can be assembled and maintained separately, which simplifies the installation and maintenance process.

[0043] In the above embodiment, the trolley is moved to the area where work is required, the brakes of the universal wheels 4 are locked, and the lifting column 3 can be extended from the side of the base plate 2, or a through hole 21 is provided on the base plate 2 for avoiding the lifting column 3. The lifting column 3 extends toward the ground through the through hole 21 and contacts the ground, thereby increasing the contact area and adhesion between the trolley and the ground, ensuring good contact between the trolley and the ground, thereby improving the stability of the trolley operation.

[0044] In one embodiment, the plurality of lifting columns 3 are evenly distributed around the frame body 1, and the height-increasing pads 5 are provided on both sides of each lifting column 3. The plurality of lifting columns 3 are evenly distributed at the bottom of the frame body 1, which helps to balance the weight of the frame body 1 and provide more stable support; the height-increasing pads 5 are provided on both sides of the lifting columns 3 to ensure that the frame body 1 remains horizontal and stable during the lifting process, which helps to prevent the frame body 1 from shaking.

[0045] In the above embodiment, the height-increasing pad 5 is a silica gel block. The silica gel block has certain softness and elasticity, and the vibration that may be generated by the chassis when the trolley is moved can be buffered and absorbed by the silica gel block to reduce the impact on the frame body 1.

[0046] In one embodiment, the height-enhancing cushion 5 is provided with a through hole 51 penetrating the height-enhancing cushion 5, and a fixing hole 11 is provided on the side of the frame body 1 close to the height-enhancing cushion 5 and the bottom plate 2. The height-enhancing cushion 5 is connected to the frame body 1 and the bottom plate 2 by passing a bolt 52 through the through hole 51 and the fixing hole 11. In order to prevent the height-enhancing cushion 5 from moving during the transportation of the trolley, the bolt 52 passes through the through hole 51 on the bottom plate 2 and the fixing hole 11 on the frame body 1, thereby strengthening the connectivity between the height-enhancing cushion 5 and the frame body 1 and the bottom plate 2, thereby improving the stability of the entire trolley.

[0047] In the above embodiment, the base plate 2 and the frame body 1 are connected as a whole through the height-increasing pad 5. When the lifting column 3 is extended, the lifting column 3 abuts against the supporting ground and bears the pressure of the trolley together with the universal wheel 4. The force-bearing area is large and the support is more stable. Of course, the lifting column 3 can also continue to extend, driving the frame body 1, the height-increasing pad 5 and the base plate 2 to rise together, and even the universal wheel 4 on the base plate 2 leaves the ground, and the weight of the trolley is supported by the lifting column 3 alone. However, in actual operation, the lifting column 3 will not extend too much to prevent the center of gravity of the trolley from being unstable after the overall rise.

[0048] In one embodiment, the frame body 1 is a rectangular parallelepiped frame with a hollowed-out middle portion. The hollowed-out middle portion of the frame body 1 can reduce the weight of the trolley while ensuring the rigidity and stability of the entire frame body 1, and can also provide a larger installation space to improve the convenience of the trolley.

[0049] In the above embodiment, the trolley further includes a control device, which is placed inside the rectangular frame. The control device includes a series of functional components such as a robot arm control box, a power supply, and a control switch of the lifting column 3, which can be safely placed in the hollow rectangular frame, thereby improving the integration of the trolley, eliminating the need for additional components, achieving a one-button start-up effect, and simplifying the difficulty of operation and deployment.

[0050] In the above embodiment, the trolley also includes a connecting member 6, and a plurality of the connecting members 6 are evenly distributed on the four sides of the rectangular frame near the bottom plate 2; the lifting column 3 is installed on the side of the rectangular frame through the connecting member 6; the connecting member 6 includes a clamping plate 62 and a bonding plate 61, one side of the bonding plate 61 is bonded and fixed to the lifting column 3, and the other side extends at least two clamping plates 62 in the direction of the rectangular frame, and the two clamping plates 62 are respectively clamped on both sides of the side and fixed to the side. One side of the bonding plate 61 extends two parallel clamping plates 62 in the direction of the rectangular frame, so that the cross section of the connecting member 6 is F-shaped, and the two parallel clamping plates 62 are just clamped on the side of the rectangular frame, and the side is provided with a side hole, and the clamping plate 62 also has a clamping hole corresponding to the side hole, and fasteners such as screws penetrate the clamping hole and the side hole at the same time, thereby increasing the stability of the assembly between the lifting column 3 and the frame.

[0051] In the above embodiment, the bonding plate 61 is vertically bonded to one end of the lifting column 3 and fixed by screws; the lifting column 3 is removed from the connecting member 6 by loosening the screws on the bonding plate 61, or the connecting member 6 and the lifting column 3 are removed from the frame body 1 together by removing the screws on the clamping plate 62. Compared with the prior art in which the upper structure of the trolley is completely dismantled and the bottom plate 2 is turned over for installation or maintenance, it is simpler and more convenient, which is conducive to improving maintenance efficiency.

[0052] Preferably, the bonding plate 61 and the clamping plate 62 are integrally formed, have higher strength and stability, and are not prone to fatigue fracture or loosening; a storage plate is horizontally provided in the middle of the rectangular frame, and the storage plate is parallel to the bottom plate 2, which can be used to place items to improve space utilization and enhance the strength and stability of the rectangular frame.

[0053] In one embodiment, a handle 7 is provided on one side of the frame body 1 away from the bottom plate 2. By providing the handle 7 on one side of the frame body 1, the operator can more easily grasp the handle 7 to push, pull or carry the entire trolley, which is convenient and quick and improves the operating efficiency; preferably, the handle 7 is a hollow arc-shaped structure with an opening toward the frame body 1, which is more convenient for manual grasping and applying force with fingers, thereby making it easier to push or pull the trolley.

[0054] In one embodiment, the trolley further includes a counterweight block, which is located at the center of one side of the bottom plate 2 close to the universal wheel 4. The presence of the counterweight block lowers the center of gravity of the trolley, effectively reducing the risk of the trolley tilting or rolling over, and allowing it to run smoothly.

[0055] The second aspect of the utility model provides a robot arm trolley, including the trolley as described in any of the above embodiments, and also including a robot arm 8 and a mounting plate 9, wherein the mounting plate 9 is mounted on a side of the frame body 1 away from the bottom plate 2, and the robot arm 8 is mounted on the mounting plate 9. The mounting plate 9 is parallel to the bottom plate 2, and is arranged on the upper part of the frame body 1, preferably in the center of the upper part of the frame body 1, and is balanced and stable. When deploying, the lifting column 3 needs to be retracted, and the trolley drives the robot arm 8 to move and deploy through the universal wheel 4, and the trolley provides a stable operating table for the robot arm 8.

[0056] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
