Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in FIGS. 1 to 5: a supporting mechanism is fixed on the base 2, and the bed board 12 is supported on the supporting mechanism through a side-turning mechanism.
The supporting mechanisms are lifting mechanisms respectively fixed at two ends of the base 2, and each lifting mechanism is composed of two first lifting oil cylinders 7 fixed on the base 2, a first lifting frame 8 fixed on piston rods of the two first lifting oil cylinders 7, two second lifting oil cylinders 11 fixed on the first lifting frame, and a second lifting frame 12 fixed on piston rods of the two second lifting oil cylinders 11.
The side-turning mechanism is composed of a supporting oil cylinder 18 and a speed reducing motor 19 which are fixed on the back of the bed plate 13, a piston rod 10 of the supporting oil cylinder 18 is matched with a bearing (not marked in the figure) fixed on the second lifting frame 12, a rotating shaft 14 of the speed reducing motor 19 is embedded into a limiting groove 15 which is fixed on the other second lifting frame 12, and a stop lever 21 is fixed on the rotating shaft 14; the rotation shaft 14 is coaxial with the piston rod 10.
In order to improve the stability and the safety of the bearing, the utility model discloses still include supplementary supporting mechanism and locking mechanism. The auxiliary supporting mechanism is composed of upright columns 4 respectively hinged on two sides of the bed plate 13, a connecting rod 17 for connecting the two upright columns 4, and a supporting seat 5 which is positioned below each upright column 4 and fixed on the base 2, wherein a U-shaped groove matched with the connecting rod 17 is arranged on the supporting seat 5. The locking mechanism is composed of a hook 6 hinged on the base 2 and a locking oil cylinder (not shown in the figure) which is arranged on the base 2 and pushes the locking hook 6 to rotate around a hinged shaft.
For the convenience of use, also for the stability that increases the bedstead simultaneously, articulated respectively on each stand 4 have supplementary support cylinder 3, and the piston rod of each supplementary support cylinder 3 is articulated with bed board 13 respectively.
In order to improve the safety when turning over the side body, the utility model discloses still include brake equipment in order to guarantee that bed board 3 can stop in the optional position at the side body in-process of turning over simultaneously. The brake device is composed of a brake block 16 fixed on the rotating shaft 14 and a hydraulic brake block 20 fixed on the second lifting frame 12.
In order to avoid the first lifting frames 8 from being inclined or swaying, the first lifting frames 8 are respectively connected with the base 2 through guide posts 9.
In order to move conveniently, the positions of the back surface of the base 2 close to the four corners are provided with the rollers 1.
The working principle is as follows: firstly, a patient is fixed on a bed by a safety belt, the hook 6 is driven to rotate clockwise around the hinge shaft by the locking oil cylinder, the hook 6 is separated from the connecting rod 17, then the auxiliary supporting oil cylinder 3 extends and pushes the upright post 4 to rotate clockwise, so that two ends of the connecting rod 17 are respectively separated from the U-shaped grooves of the two corresponding supporting seats 5 (at the moment, the whole bed plate 13 is supported on the two second lifting frames 12 by the piston rod 10 of the supporting oil cylinder 18 and the rotating shaft 14 of the reducing motor 19 together). Finally, the whole bed plate 13 can be driven to turn laterally along the opposite direction of the rotation of the speed reducing motor 19 under the driving of the reaction force of the rotation of the speed reducing motor 19, so that the lying on the side or the prone position can be realized. The lateral position or the prone position is also beneficial to operations such as body position drainage, mechanical auxiliary ventilation and the like. When the lathe bed turns over to a preset angle, the brake block 16 is clamped and locked by the hydraulic brake block 20. When the lathe bed needs to be lifted, only two first lifting oil cylinders 7 positioned at the head end (left end) of the lathe bed and two first lifting oil cylinders 7 positioned at the tail end (right end) of the lathe bed are needed to be started; if the bed body is lifted to the highest position, the second lifting oil cylinders 11 respectively positioned at the head end and the tail end of the bed body are started, and then the bed plate 13 can be lifted to the highest position through the second lifting frames 12.
