Displacement vehicle

Abstract

The invention discloses a displacement vehicle which comprises a vehicle body and a moving bed plate mechanism, wherein the vehicle body is provided with a lifting mechanism; universal foot wheels aremounted on the vehicle body; the moving bed plate mechanism is used for receiving and transporting patients in a transversely moving manner; the moving bed plate mechanism is mounted on the frame ofthe vehicle body; the moving bed plate mechanism comprises a cloth coiling shaft frame, a cloth coiling shaft, an end connector base, an upper moving plate, lower moving cloth, a lower moving plate, lower moving cloth, a first chain wheel assembly and a ratchet wheel assembly. The displacement vehicle is characterized in that due to arrangement of the first chain wheel assembly, the ratchet wheelassembly and a first chain wheel motor, a conventional transmission mode that a clutch gear, a long rack, a clutch and a clutch driving mechanism cooperate with one another is replaced, the transmission structure of the moving bed plate mechanism is greatly simplified, the displacement vehicle is compact in structure and smooth in transmission, meanwhile, operation of the displacement vehicle is humanized, and positions of the patients can be corrected in necessary.

Description

technical field [0001] The invention relates to a transport tool technology for loading and unloading patients, in particular to a medical patient lifting vehicle suitable for transporting postoperative patients in hospitals or transporting patients who are easily injured again during the transport process. Background technique [0002] At present, the lifting cart is used to move and transfer patients with mobility problems before and after the operation, and move the patient from the hospital bed to the lifting cart, and then from the lifting cart to the operating table or equipment requiring examination / treatment, or reverse transfer. Especially for patients with wounds or patients who have undergone severe spine, cervical spine, and thoracic spine operations, the birth of the lifting car reduces the labor intensity of medical staff and avoids the possibility of bringing the patient several times during the transfer period before and after surgery. The secondary injury of...

Problems solved by technology

[0004] The way to realize the autorotation or stop autorotation of the cloth winding shaft adopts the joint cooperation of the clutch gear, the long rack, the clutch, and the clutch driving mechanism, as shown in the accompanying drawings 16-17 of this patent specification. The disadvantage is that the design structure is complicated, the control method is complicated, and it is easy to Fault occurs; if the clutch adopts the jaw clutch, that is, the mechanical control structure that engages and separates the two clutch gears through the fixed clutch gear and the movable clutch gear, when it needs to be combined, when the two teeth of the two clutch gears are not coordinated , it will cause the combination to be not smooth, and when separation is required, there will be separation resistance when the two teeth are meshed, resulting in a large difference in movement and positioning, and the transfer of the patient cannot be completed satisfactorily.

[0005] Another example is the attached patent specification Figure 11-12 , as shown in Figure 17, the clutch drive mechanism adopts multiple transmission modes such as small rack, pinion, tension rod, rocker arm, and push rod. The structure and transmission mode are complicated, and the failure rate is also increased.
