[0034] like Figure 1 , Figure 2 As shown, some embodiments of the present application provide a mobile trolley with a movable pallet, including a base 1, a pallet 2, a first driving member 3 and a second driving member 4. The pallet 2 is located on the upper surface of the base 1, and the first driving member 3 and the second driving member 4 are connected to the pallet 2. The pallet 2 can move left and right, front and back on the base 1 under the drive of the first driving member 3 or the second driving member 4, so that the center of gravity of the pallet 2 is consistent with the center of gravity of the workpiece to be transferred, so as to avoid the workpiece to be transferred from the pallet 2 after being placed on the pallet 2 during the transfer process, thereby damaging the workpiece to be transferred and reducing the production cost.

[0035] Exemplarily, the fixed ends of the first driving member 3 and the second driving member 4 are mounted on the tray 2, and the driving ends are movably connected to the base or other structural members. Alternatively, the fixed ends of the first driving member 3 and the second driving member 4 are movably connected to the base or other structural members, and the driving ends are connected to the tray 2.

[0036] Exemplarily, the first driving member 3 and the second driving member 4 can be configured as a linear motor, a cylinder, etc.

[0037] It should be noted that the workpiece to be transferred is a pipeline flow meter.

[0038] In some embodiments, a moving assembly 5 is installed below the tray 2, and the moving assembly 5 is located between the base 1 and the tray 2. The moving assembly 5 includes a rolling member 51. When the tray 2 moves under the drive of the first driving member 3 and / or the second driving member 4, the rolling member 51 rolls on the base 1, which can reduce the driving force of the first driving member 3 and / or the second driving member 4 to drive the tray 2 to move, which is conducive to reducing costs.

[0039] Exemplarily, the rolling element 51 may be configured as a structural element having a ball or the like.

[0040] Figure 3 is a schematic structural diagram of a mobile assembly according to some embodiments of the present application. Figure 3 As shown, specifically, the moving assembly 5 further includes an adapter 52 and an elastic member 53 installed below the tray 2. The adapter 52 is provided with a cavity having an opening, the rolling member 51 is located in the cavity and extends out from the opening, and the two ends of the elastic member 53 are respectively abutted against the rolling member 51 and the inner wall of the cavity away from the rolling member 51. Under the action of the restoring force of the elastic member 53, the moving assembly 5 can play the role of supporting the tray 2.

[0041] Exemplarily, the elastic member 53 may be configured as a spring, an elastic structural member, etc.

[0042] In some embodiments, a tray bracket 6 is also installed between the tray 2 and the moving assembly 5, and the first driving member 3 and the second driving member 4 are both installed on the tray bracket 6 and distributed up and down on the tray bracket 6. There is no direct contact between the first driving member 3 and the second driving member 4, so that the two will not interfere with each other when working.

[0043] Specifically, a support portion 61 is provided below the tray 2 bracket. When the workpiece to be transferred is not placed on the tray 2, the tray 2 and the tray bracket 6 are supported by the elastic member 53, so that there is a gap between the support portion 61 and the base 1; when the workpiece to be transferred is placed on the tray 2, the elastic member 53 is not sufficient to support the above-mentioned structural member under the action of the gravity of the workpiece to be transferred, the tray 2 and the tray bracket 6, so that the elastic member 53 is further compressed and the rolling member 51 retreats into the cavity. At this time, the support portion 61 abuts against the base 1 to support the workpiece to be transferred, the tray 2 and the tray bracket 6.

[0044] It should be noted that, when the center of gravity of the pallet 2 moves to coincide with the center of gravity of the workpiece to be transferred, the workpiece to be transferred will be placed on the pallet 2. After the workpiece to be transferred is placed on the pallet 2, the pallet 2 will not move any more.

[0045] Exemplarily, the shape of the contact surface between the tray 2 and the workpiece to be transferred is determined by the shape of the workpiece to be transferred, so as to increase the contact area between the workpiece to be transferred and the tray 2, and prevent the contact surface between the workpiece to be transferred and the tray 2 from being crushed due to its own gravity. Since the workpiece to be transferred in the present application is a pipeline flow meter, the contact surface between the tray 2 and the workpiece to be transferred is set to an arc shape, and the height of the arc shape is greater than the radius of the pipeline flow meter, which can prevent the pipeline flow meter from sliding off the tray 2.

[0046] In some embodiments, a vehicle body 7 is also mounted on the base 1, and the base 1 and the vehicle body 7 form a receiving cavity with an open top, and the tray 2, the tray support 6 and the moving assembly 5 are all arranged in the receiving cavity, which can improve the aesthetics of the present application. Among them, the tray 2 is located above the receiving cavity to receive and transfer workpieces.

[0047] In some embodiments, a limiting rod 31 is installed on the driving end of the first driving member 3 and the second driving member 4, and a guide track 71 corresponding to the limiting rod 31 is provided on the inner wall of the vehicle body 7, and the limiting rod 31 cooperates with the guide track 71. When the first driving member 3 and / or the second driving member 4 drives the tray 2 to move, the limiting rod 31 moves along the guide direction of the guide track 71, and the movement of the tray 2 can be guided to prevent the tray 2 from deviating from the predetermined moving track.

[0048] Exemplarily, at least two guide bars are installed on two opposite inner walls of the vehicle body 7 to form a guide track 71, and the limit rod 31 is located between the two guide bars to guide the movement of the tray 2. Alternatively, a linear guide is installed on the inner wall of the vehicle body 7, and the limit rod 31 is connected to a slider of the linear guide, and the limit rod 31 moves synchronously with the slider.

[0049] In some embodiments, a roller 8 and a third driving member are installed below the base 1. The third driving member drives the roller 8 to rotate, which can drive the moving trolley to move, so as to transfer the workpiece to be transferred to the next workstation.

[0050] Specifically, in order to rotate the rollers 8, a rotating shaft 9 is further provided under the base 1. Every two rollers 8 are connected by the rotating shaft 9, and the rotating shaft 9 is connected to the driving end of the third driving member. The third driving member drives the rotating shaft 9 to rotate, so as to drive the rollers 8 to rotate, thereby moving the mobile vehicle.

[0051] It should be noted that, in order to make the mobile trolley move smoothly, two sets of rotating shafts 9 and rollers 8 can be provided, and the two rotating shafts 9 can be driven by the third driving member at the same time, or each rotating shaft 9 can be driven by the third driving member.

[0052] Exemplarily, the third driving member may be configured as a motor or the like.

[0053] In some embodiments, a detection element 10 is installed on the tray 2. When the detection element 10 detects the workpiece to be transferred, it indicates that the workpiece to be transferred is placed on the tray 2. Then the third driving member drives the rotating shaft 9 to rotate, thereby driving the roller 8 to rotate and transfer the workpiece to be transferred to the next workstation.

[0054] Exemplarily, the detection element 10 may be configured as a proximity switch or the like.

[0055] To sum up, the utility model provides a mobile trolley with a movable pallet, in which a first driving member and a second driving member are both connected to the pallet, and the pallet is driven to move left and right by the first driving member, and the pallet is driven to move forward and backward by the second driving member to adjust the position of the pallet on the base so that the center of gravity of the pallet is consistent with the center of gravity of the workpiece to be transferred, thereby preventing the workpiece to be transferred from falling off the pallet during the transfer process after being placed on the pallet, thereby reducing production costs, and the structure is simple and practical.
