[0002] CT scanners are large medical devices typically used in hospitals. Their transportation is limited by factors such as elevator size or shielded room door dimensions, preventing the use of general transport vehicles like forklifts, pallet trucks, or pallet trolleys. Specialized vehicles are required. However, existing CT scanner transport carts have two steering mechanisms for horizontal movement, both manually propelled. These mechanisms suffer from instability and excessively large turning radii, requiring more space for maneuvering and making them unsuitable for use in confined spaces such as elevators, narrow corridors, and shielded room doors.

[0006] In some embodiments, the support mechanism includes a support pad that matches a pre-set positioning slot structure at the bottom of the CT scanner and is configured to be inserted into the positioning slot to position the support mechanism in conjunction with the CT scanner.

[0007] In some embodiments, the differential steering hydraulic CT transport trolley further includes: an anti-loosening fastening bolt, which passes through the support pad and the positioning slot, and is configured to lock the relative position of the support pad and the CT machine to prevent the CT machine from slipping relative to the carrier mechanism during transport.

[0008] In some embodiments, the differential steering mechanism further includes a power supply mechanism disposed on the bracket body, the power supply mechanism including a power supply interface, the power supply interface being matched with the output terminal of the CT scanning gantry's built-in battery, and configured to supply power to the integrated motor wheel.

[0010] In some embodiments, the differential steering hydraulic CT transport trolley further includes: wheel guards, disposed outside each integrated motor wheel, configured to prevent ground debris from being rolled into the wheel body, thus avoiding debris jamming and causing integrated motor wheel failure.

[0011] A second aspect of this application provides a transport system for a CT scanner, comprising: at least two transport trolleys as provided in the first aspect of this application; and a wireless controller, which establishes a signal connection with the controller of each integrated motor wheel and is configured to send speed control commands to the controller of the integrated motor wheel to realize remote control of the differential steering mechanism.

[0012] In some embodiments, the transport system applied to the CT scanner further includes: an external backup battery pack connected in parallel with the drive motors of the plurality of integrated motor wheels, configured to provide backup power when the CT scanner's own battery is low, ensuring the continuous operation of the differential steering mechanism.

[0013] Compared with related technologies, the above-described solutions of this application have at least the following beneficial effects: The differential steering hydraulic CT transport trolley and transport system provided in this application allow for independent speed control of each integrated motor wheel of the differential steering mechanism.

[0029] The purpose of this utility model is to provide a differential steering hydraulic CT transport trolley and transport system. Through the synergistic action of the differential steering mechanism, hydraulic lifting mechanism and load-bearing mechanism, it solves the technical problems in related technologies such as inflexible equipment steering, difficult lifting, unstable load bearing, inconvenient power supply and low control precision, so as to realize the safe transport of CT machines.

[0030] The optional embodiments of this application are described in detail below with reference to the accompanying drawings.

[0031] This application provides a differential steering hydraulic CT transport vehicle, comprising at least two vehicle bodies 1000, such as... Figure 1 As shown, the vehicle body 1000 includes a support body 100, a load-bearing mechanism 200, a hydraulic lifting mechanism 300, and a differential steering mechanism 400. The support body 100 is the core support structure of the vehicle body 1000, used to bear the weight of the CT machine 2000 and provide a mounting carrier for other components of the vehicle body 1000. The load-bearing mechanism 200 is in direct contact with the CT machine 2000 and is configured to support the transportation of the CT machine 2000. The hydraulic lifting mechanism 300 is configured to drive the load-bearing mechanism 200 to move along the slide rail 110, realizing the vertical movement of the CT machine 2000. The differential steering mechanism 400 is configured to drive the entire vehicle body 1000 to move relative to the ground, realizing actions such as turning around or steering on the spot.

[0032] In some embodiments, the bottom of the bracket body 100 is provided with a mounting seat for mounting the differential steering mechanism 400, the middle is reserved with an assembly cavity for the hydraulic lifting mechanism 300, and the side is provided with a power supply interface and a fixed bracket for the wheel guard, providing a stable assembly base support for other functional components of the vehicle body 1000. The bracket body 100 has an overall rectangular frame structure, which can reasonably allocate the assembly space of each component, making the overall layout of the vehicle compact and suitable for narrow transportation scenarios.

[0033] In some embodiments, the support body 100 can be welded from high-strength steel plates to meet the heavy-load transport requirements of the CT scanner 2000, ensuring that the structure of the support body 100 does not deform or loosen during heavy-load transport. The steel plates have both high strength and impact resistance, providing stable support for CT transport.

[0034] In some embodiments, the support body 100 is a rigid frame structure that bears the weight of the entire CT machine 2000 during transportation while maintaining structural stability, and provides an installation carrier for other components such as the load-bearing mechanism 200, the hydraulic lifting mechanism 300, and the differential steering mechanism 400.

[0035] In some embodiments, such as Figure 1 As shown, a slide rail 110 is provided on one side of the support body 100. The supporting mechanism 200 includes a supporting part, which is connected to the support body 100 via the slide rail 110. The slide rail 110 allows the supporting part to move relative to the support body 100 along the extension direction of the slide rail 110, configured to enable the supporting part to drive the CT scanner 2000 to move in a direction perpendicular to the ground. Stops are provided at both ends of the slide rail 110 to limit the range of motion of the supporting part.

[0036] In some embodiments, the support portion further includes a support pad 210, which is a rectangular block structure. The shape of the support pad 210 matches the pre-set positioning slot structure on the bottom of the CT scanner 2000, and its surface is provided with protrusions corresponding to the positioning slot. The support pad 210 may be made of wear-resistant and elastic polyurethane material, which can both prevent scratching the bottom of the CT scanner 2000 and enhance the fit between the support pad 210 and the CT scanner 2000.

[0037] The support pad 210 is installed on the upper surface of the bearing unit by welding or bolting, and is also equipped with anti-loosening fastening bolts 220, which are used to pass through the positioning slots at the bottom of the CT machine 2000 and the support pad 210. When the support pad 210 is inserted into the positioning slots at the bottom of the CT machine 2000, it can achieve precise engagement and positioning between the bearing mechanism 200 and the CT machine 2000, preventing horizontal displacement of the CT machine 2000 on the bearing mechanism 200, and effectively avoiding slippage of the CT machine 2000 relative to the bearing mechanism 200 when encountering slopes or turns during transportation.

[0038] In some embodiments, a rubber washer is provided between the anti-loosening fastening bolt 220 and the support pad 210. On the one hand, it prevents the support pad 210 from being damaged when the bolt is tightened. On the other hand, the elastic deformation of the rubber washer enhances the anti-loosening effect, ensuring that the CT machine 2000 and the load-bearing mechanism 200 remain relatively stationary when moving on bumpy roads, effectively preventing the CT machine 2000 from slipping or shifting, and ensuring the safety of transporting precision equipment.

[0039] In some embodiments, the hydraulic lifting mechanism 300 is a telescopic structure, disposed on the support body 100, and includes a hydraulic support mechanism, a lift foot valve 321 and a lower foot valve 322.

[0040] The hydraulic jacking mechanism consists of a hydraulic cylinder 311 and a telescopic rod 312. The hydraulic cylinder 311 is a single-acting hydraulic cylinder and is fixedly connected to the support body 100. At least a portion of the telescopic rod 312 is slidably disposed within the hydraulic cylinder 311. The top of the support rod is provided with a top support surface. In response to the telescopic rod 312 extending a preset length, the top support surface abuts against the bottom of the bearing mechanism 200 for support. At this time, the telescopic rod 312 continues to extend, which will drive the bearing mechanism 200 to move away from the ground along the slide rail 110.

[0041] The lifting foot valve 321 and the lowering foot valve 322 are respectively connected to the oil inlet and oil outlet of the hydraulic cylinder 311 through hydraulic pipelines. The hydraulic pipelines are made of high-pressure rubber hoses and are fixed to the longitudinal beam of the support body 100 by pipe clamps.

[0042] When the operator steps on the lift foot valve 321, the hydraulic oil in the hydraulic line enters the hydraulic cylinder 311, pushing the telescopic rod 312 to extend. The telescopic rod 312 lifts the bearing mechanism 200 through the connecting seat, causing the bearing mechanism 200 to rise vertically relative to the support body 100 along the slide rail 110. The distance between the bearing mechanism 200 and the ground is adjusted so that the bearing mechanism 200 can lift the CT machine 2000.

[0043] When the operator steps on the lowering foot valve 322, the hydraulic oil in the hydraulic cylinder 311 flows back through the hydraulic pipeline. Under the gravity of the bearing mechanism 200 and the CT machine 2000, the telescopic rod 312 retracts into the hydraulic cylinder 311, and the bearing mechanism 200 descends accordingly, so that the bearing mechanism 200 drives the CT machine 2000 to descend.

[0044] Compared to traditional screw-type structures, the hydraulic lifting mechanism 300 provided in this application adopts a foot-operated structure, which occupies less space and can easily achieve lifting operations, thus saving effort. Therefore, when adjusting the vehicle body 1000, it does not require excessive space, and no additional transfer equipment is needed in confined spaces such as elevators, narrow corridors, and shielded room doors, solving the problems of laborious and space-consuming existing screw-type lifting mechanisms.

[0045] In some embodiments, the supporting mechanism 200 further includes a limiting boss 230, which is disposed at the end of the supporting mechanism 200 away from the ground and extends at least partially toward the other side of the support body 100. This allows the limiting boss 230 to abut against the support body 100 when the supporting mechanism 200 descends relative to the support body 100 to a limiting position, thereby restricting further movement of the supporting mechanism 200. Combined with the hydraulic lifting mechanism 300, damage to the CT machine 2000 due to a sudden descent of the supporting mechanism 200 can be effectively avoided, improving the safety and reliability of the hydraulic CT transport trolley operation and making the vehicle body 1000 particularly suitable for the smooth lifting and lowering requirements of heavy equipment such as the CT machine 2000.

[0046] In some embodiments, the differential steering mechanism 400 includes at least two integrated motor wheels, each of which is a modular structure consisting of a drive motor, a controller, and a wheel body. The drive motor may be a DC 24V permanent magnet motor, and the controller is integrated into a sealed aluminum housing on the side of the wheel body and is electrically connected to the drive motor via built-in wires. The at least two integrated motor wheels are configured to output different speeds to form a differential, enabling linear movement and on-the-spot steering of the vehicle body 1000.

[0047] In some embodiments, the integrated motor wheel includes a planetary gear reduction mechanism, which is fixedly connected to the output shaft of the drive motor and the hub of the integrated motor wheel by bolts. It is configured to reduce the output speed of the drive motor and increase the torque, so as to ensure that the integrated motor has sufficient driving force to move the CT transport trolley and the CT machine 2000.

[0048] In some embodiments, the differential steering mechanism 400 further includes a power supply mechanism, which includes a DC 24V power supply interface disposed on the bracket body 100. The shape and electrical parameters of the power supply interface match the output terminal of the CT scanner's built-in battery. The power supply interface is detachably electrically connected to the output terminal of the CT scanner's built-in battery and is configured to power the integrated motor wheels. In this embodiment, the vehicle body 1000 can be powered directly from the CT scanner 2000's built-in battery, eliminating the need to carry a heavy external battery, reducing the vehicle's carrying burden, and avoiding the problem of inconvenient power supply.

[0049] In some embodiments, the outer side of the integrated motor wheel is wrapped with an anti-slip rubber layer to increase the coefficient of friction between the wheel and the ground. Designed for smooth surfaces such as polished ceramic tiles in hospitals, this effectively prevents wheel slippage during differential steering of the vehicle body, improves steering stability, ensures stable transport of the CT scanner 2000, and further enhances transport safety.

[0050] In some embodiments, the vehicle body 1000 also includes wheel guards, which are U-shaped metal shells disposed on the outside of each integrated motor wheel, with the opening facing the ground. The top of the wheel guard is fixedly connected to the guard bracket at the bottom of the bracket body 100 by bolts. An 8-10mm gap is reserved between the inner wall of the guard and the wheel to prevent ground debris from being rolled into the wheel. The structural design of the wheel guards can effectively prevent cables, paper scraps, dust, and other debris that may be present on the hospital floor from entering the drive mechanism and axle of the integrated motor wheel, avoiding debris jamming and causing integrated motor wheel failure, ensuring the continuous and stable operation of the differential steering mechanism 400, and reducing the equipment failure rate.

[0051] A second aspect of this application provides a transport system for a CT scanner 2000, including the CT scanner 2000, a differential-steering hydraulic CT transport trolley, a wireless controller, and an external backup battery pack. For example... Figure 4 , Figure 5 As shown, two opposing and symmetrically arranged vehicle bodies 1000 are used to carry and move the CT scanner 2000 to realize the transportation of the CT scanner.

[0052] In some embodiments, the wireless controller is a handheld portable structure with a built-in wireless communication module. It establishes a bidirectional signal connection with the controller of each integrated motor wheel via wireless signal, and is configured to send differentiated speed control commands to the controller of the integrated motor wheel to achieve remote control of the differential steering mechanism 400. The bidirectional signal connection allows operators to obtain the trolley's operating data in real time, accurately adjust the steering angle and moving speed, avoid the risk of collision caused by close-range operation, adapt to the operating needs of confined spaces in hospitals, and improve transport efficiency and safety.

[0053] In some embodiments, such as Figure 5 As shown, the controller of the integrated motor wheel establishes a signal connection with the wireless controller through a wireless communication module. The controller is equipped with an antenna for receiving wireless signals. When turning is required, the controller of each integrated motor wheel can receive a speed control command sent by the wireless controller, causing the integrated motor wheels on both sides to output different speeds to form a speed difference. For example, the speed of the left integrated motor wheel is 0, while the right integrated motor wheel rotates normally, or the two integrated motor wheels rotate in opposite directions, thereby enabling the transport cart to turn on the spot. This solves the problems of large turning radius when there is a directional wheel on one side and a swivel wheel on the other side in traditional transport carts, and unstable movement when there are swivel wheels on both sides. It improves the flexibility of the transport cart in the complex and confined environment of the hospital.

[0054] In some embodiments, the external backup battery pack of the transport system is a DC24V rechargeable lithium battery pack, configured to provide backup power when the CT machine 2000's built-in battery is low. The external backup battery pack is detachably installed on the support body 100 via a snap-fit ​​structure, facilitating charging and replacement, ensuring the continuous operation of the differential steering mechanism 400, preventing the transport process from stalling due to power outages, and ensuring the continuity of the CT machine 2000 transfer process.

[0055] When using the differential steering hydraulic CT transport trolley and transport system of this application, firstly, according to the weight of the CT machine 2000 and the bottom support structure, at least two vehicle bodies 1000 are symmetrically arranged on both sides of the bottom of the CT machine 2000. The vehicle bodies 1000 are pushed so that the support pads 210 of the bearing mechanism 200 are aligned with the positioning slots on the bottom of the CT machine 2000. The support pads 210 are slowly inserted into the slots to complete the initial locking and positioning. Then, the anti-loosening fastening bolts 220 are passed through the connection between the support pads 210 and the positioning slots, and the anti-loosening nuts are tightened to lock the CT machine 2000 and the bearing mechanism 200.

[0056] After initial positioning, the operator steps on the lift foot valve 321, opening the hydraulic circuit and increasing the hydraulic oil pressure in the hydraulic cylinder 311, pushing the telescopic rod 312 to extend. When the telescopic rod 312 extends to the preset length, its top end abuts against the bottom of the support mechanism 200 for support and continues to lift, driving the support mechanism 200 to rise vertically along the guide rail, raising the CT machine 2000 to the preset height. The wireless controller sends speed control commands to the controllers of each integrated motor wheel, selecting the steering mode according to the transportation scenario requirements: when turning in place is required, the two diagonally opposite integrated motor wheels are controlled to output reverse speeds; when straight-line movement or small-radius turning is required, the integrated motor wheels on the same side are controlled to output different speeds, driving the trolley to move.

[0057] Once the CT scanner 2000 has been transported to its target location, the foot pedal 322 is depressurized, releasing pressure in the hydraulic circuit. The telescopic rod 312 slowly retracts under the weight of the CT scanner 2000, causing the supporting mechanism 200 to descend along the guide rail, and the CT scanner 2000 lands smoothly. Finally, the anti-loosening bolts 220 are loosened, the support pads 210 are removed from the positioning slots, and the vehicle body 1000 is moved, completing the transfer of the CT scanner 2000. If the CT scanner 2000's built-in battery is low, the power switch will switch to an external backup battery pack to ensure continuous power supply during transport.

[0058] In this application, the speed of each integrated motor wheel of the differential steering mechanism 400 can be controlled independently, such as... Figure 5 As shown, the four-corner layout design of multiple motor wheels makes it easy to turn on the spot and turn with a small radius, which is suitable for the transportation needs of hospitals with narrow spaces. The hydraulic lifting mechanism 300 replaces the traditional screw structure, which is easy to operate and occupies little space. It has strong heavy load adaptability. The differential steering mechanism 400 works in conjunction with the hydraulic lifting mechanism 300 to improve the flexibility of the transport vehicle in the complex and narrow environment of the hospital.
