[0021] 1. In the present invention, by arranging corresponding walking wheel assemblies on the frame, the whole trolley has the function of walking. At the same time, a lifting mechanism is arranged on the frame, so that the trolley has the function of lifting and lowering the operating table. More specifically, since two lifting units are arranged in the lifting mechanism, and the two lifting units are arranged on both sides of the frame in sequence, the stability of the lifting mechanism in taking the operating table is improved. In addition, since two lifting pillars are arranged in one lifting unit, and the two lifting pillars are synchronously driven by the synchronous pulley assembly arranged on the frame, the two lifting pillars in one lifting unit are synchronously lifted and lowered, thereby enhancing the control of the lifting pillar on the stability of the operating table support, thereby improving the stability of the operation of taking and transporting the operating table.

[0022] 2. In the present invention, since two walking wheel groups are arranged in the walking unit and the two walking wheel groups are symmetrically arranged on the support guide plate, the stability of supporting and conveying the support guide plate is further enhanced. Furthermore, since a wheel group fixing frame is arranged in the walking wheel group, the fixed installation of the driving motor, the speed change gear group and the roller on the support guide plate is realized. More specifically, the driving motor is arranged to drive the roller through the speed change gear group to realize the regulation of the roller speed and obtain the appropriate rotation speed, which is beneficial to the operation of the trolley during work.

[0023] 3. In the present invention, a lifting outer cylinder is arranged in the lifting pillar, and a screw assembly is arranged in the lifting outer cylinder to realize the lifting and lowering of the lifting inner cylinder relative to the lifting outer cylinder, thereby realizing the lifting and lowering control of the tightening head arranged on the top of the lifting inner cylinder. More specifically, since the lower end of the lifting inner cylinder is fixedly arranged with the movable block in the screw assembly, when the screw assembly is driven, the movable block in the screw assembly is lifted and lowered in the lifting outer cylinder, thereby the lifting inner cylinder fixedly connected with the movable block realizes a stable telescopic operation relative to the lifting outer cylinder, thereby realizing the power supply for lifting and lowering the operating table.

[0024] 4. In the present invention, since a bearing seat is provided in the screw rod assembly and a screw rod is provided in the bearing seat, a passive synchronous wheel is fixedly provided at the bottom of the screw rod, and the rotation operation of the screw rod is realized by driving the passive synchronous wheel to rotate, and the bearing seat realizes the protection of the stability of the screw rod during the rotation process. More specifically, the movable block is slidingly arranged in the lifting outer cylinder along the height direction of the lifting outer cylinder, thereby providing a lifting and sliding guide path for the movable block in the lifting outer cylinder, preventing the movable block from rotating in the lifting outer cylinder under the action of the screw rod. Therefore, the threaded connection between the screw rod rotating with a fixed axis in the vertical direction and the movable block, the rotating screw rod provides the driving operation of the movable block along the sliding guide direction of the lifting outer cylinder, thereby realizing the stable lifting control of the movable block in the lifting outer cylinder, thereby achieving the stable lifting control between the lifting inner cylinder fixedly connected to the movable block and the lifting outer cylinder.

More specifically, a bottom plate fixedly arranged with the upper end of the lifting inner cylinder is provided in the tightening head, and a guide rail is fixedly provided on the bottom plate and a sliding support plate is provided at the sliding end of the guide rail. The bottom of the operating table is relatively supported by a locking assembly provided on the sliding support plate.

At the same time, by providing a locking assembly on the sliding support plate, the movable end of the locking assembly can be tightened against the bottom plate, so as to achieve a tightening limit for the sliding support plate to be relatively fixedly installed with the bottom plate after sliding adjustment.

[0026] 6. In the present invention, a servo motor is arranged in the synchronous pulley assembly, the active synchronous wheel is driven by the servo motor, and the passive synchronous wheel in the two lifting pillars arranged on the support guide plate is connected to the active synchronous wheel through a synchronous belt, so as to realize simultaneous driving of the two lifting pillars and synchronous control of the lifting operations of the two lifting pillars. At the same time, according to actual needs, a tensioning adjustment shaft group is arranged to adjust the tension of the synchronous belt passing through the active synchronous wheel, so as to improve the stability of the rotation transmission of the synchronous belt. More specifically, a mounting plate is arranged to enable the adjustment shaft to be installed for position adjustment relative to the support guide plate, so as to realize tension control.

[0027] 7. In the present invention, since a detachable reinforcing crossbeam is provided between the lifting pillars which are arranged opposite to each other on the two support guide plates, it effectively avoids the dragging between the operating table and the lifting pillars when the operating table is taken and transferred on the lifting pillars, causing the lifting pillars to shake on the support guide plates and making the installation of the lifting pillars unstable. Therefore, by providing a detachable reinforcing crossbeam, the stability of the fixed installation of the lifting pillars on the support guide plates is improved. BRIEF DESCRIPTION OF THE DRAWINGS

More specifically, since the lower end of the lifting inner cylinder 19 is fixed to the movable block 20 in the screw assembly 17; therefore, when the screw assembly 17 is driven, the movable block 20 in the screw assembly 17 is lifted and lowered in the lifting outer cylinder 16, thereby the lifting inner cylinder 19 fixedly connected to the movable block 20 realizes a stable telescopic operation relative to the lifting outer cylinder 16, thereby realizing the power supply for lifting and lowering the operating table.

More specifically, the movable block 20 is slidably arranged in the lifting outer cylinder 16 along the height direction of the lifting outer cylinder 16, thereby providing a lifting and sliding guide path for the movable block 20 in the lifting outer cylinder 16, preventing the movable block 20 from rotating in the lifting outer cylinder 16 under the action of the screw 22.

In addition, due to the setting of the guide rail 25, the supporting sliding support plate 26 can be adjusted to slide in the lateral direction of the surgical table, thereby better supporting the surgical tables of different sizes after adaptive adjustment. At the same time, by setting the locking assembly 27 on the sliding support plate 26, the movable end of the locking assembly 27 can be set to tighten with the bottom plate 24, so as to achieve the tightening limit of the sliding support plate 26 being relatively fixedly installed with the bottom plate 24 after sliding adjustment.

Therefore, by providing a detachable reinforcing crossbeam 37, the stability of the fixed installation of the lifting pillars 7 on the support guide plates 9 is improved.

[0062] Working principle and working process of the present invention:

[0063] When an automatic guided vehicle for replacing an operating table provided by the present invention is used, a corresponding walking wheel assembly 2 is arranged on the set frame 1, so that the entire vehicle has the function of walking; at the same time, a lifting mechanism 5 is arranged on the frame 1, so that the vehicle has the function of lifting and lowering the operating table; more specifically, since two lifting units 6 are arranged in the lifting mechanism 5, and the two lifting units 6 are arranged on both sides of the frame 1 in sequence, the stability of the lifting mechanism 5 in taking the operating table is improved. In addition, since two lifting pillars 7 are arranged in one lifting unit 6, and the two lifting pillars 7 are synchronously driven by the synchronous pulley assembly 8 arranged on the frame 1, the two lifting pillars 7 in one lifting unit 6 are synchronously lifted and lowered, thereby enhancing the control of the lifting pillar 7 on the stability of the operating table support, thereby improving the stability of the operation of taking and transporting the operating table.

[0064] Furthermore, by setting a lifting outer cylinder 16 in the lifting pillar 7 and setting a screw assembly 17 in the lifting outer cylinder 16, the lifting inner cylinder 19 can be lifted relative to the lifting outer cylinder 16, thereby realizing the lifting and lowering control of the clamping head 18 set on the top of the lifting inner cylinder 19. More specifically, since the lower end of the lifting inner cylinder 19 is fixed to the movable block 20 in the screw assembly 17; therefore, when the screw assembly 17 is driven, the movable block 20 in the screw assembly 17 is lifted and lowered in the lifting outer cylinder 16, thereby the lifting inner cylinder 19 fixedly connected to the movable block 20 realizes a stable telescopic operation relative to the lifting outer cylinder 16, thereby realizing the power supply for lifting and lowering the operating table.

[0065] Therefore, by setting a servo motor 30 in the synchronous pulley assembly 8, the active synchronous wheel 31 is driven by the servo motor 30, and the passive synchronous wheel 23 in the two lifting pillars 7 set on the support guide plate 9 is connected to the active synchronous wheel 31 through the synchronous belt 32, so as to realize the simultaneous driving of the two lifting pillars 7 and the synchronous control of the lifting operation of the two lifting pillars 7; at the same time, according to actual needs, a tensioning adjustment shaft group 34 is set to adjust the tension of the synchronous belt 32 passing through the active synchronous wheel 31, so as to improve the stability of the rotation transmission of the synchronous belt 32; more specifically, a mounting plate 36 is set to enable the adjustment shaft 35 to be installed relative to the support guide plate 9 for position adjustment, so as to realize the tension control.
