The first turntable 25 is arranged in the first shell 24 and fixedly mounted on the surface of the first rotating shaft 5.

The second electromagnetic telescopic pin 23 can be inserted into the limiting groove 22.

[0043] An electromagnetically driven brake mechanism 31 is disposed in both the first shell 24 and the second shell 20. The electromagnetically driven brake mechanism 31 can clamp the first turntable 25 or the second turntable 21 to achieve braking, thereby improving the safety of the traction machine lifting the patient. The electromagnetically driven brake mechanism 31 belongs to the prior art and will not be elaborated here.

[0044] Operation method and principle: 1) Spread the support cloth 10 on the upper side of the bed 1, and the patient lies on the upper side of the support cloth 10, and manually rotate the first cylinder 7 and the second cylinder 8 to Figure 8As shown, the support cloth 10 is tied to the beams 9 on both sides by connecting ropes. At this time, the telescopic end of the first electromagnetic telescopic pin 28 extends out and inserts into the position between the two limit blocks 26, and the telescopic end of the second electromagnetic telescopic pin 23 extends out and inserts into the limit groove 22. Figure 8 As shown;

[0045] 2) The air pump delivers air to the two center of gravity regulators 11 through the input air pipe 19, and the two center of gravity regulators 11 deliver air to the first cylinder 7 and the second cylinder 8 through the output air pipe 18 respectively:

[0046] a. The center of gravity G1 of the load on the support cloth 10 is Fig. 9 Taking the position shown in the figure as an example, since the first cylinder 7 and the second cylinder 8 can rotate within a certain range of angles (the angle is determined by the two limit blocks 26 and the limit grooves 22), under the action of the center of gravity G1 and the lifting of the first cylinder 7 and the second cylinder 8, the first cylinder 7 and the second cylinder 8 rotate to Fig. 9 In the state shown, at this time, the left side of the support cloth 10 is not separated from the bed body (refer to Figure 2 As shown), and the rotation angles of the rotating air sleeves 15 in the left and right center of gravity regulators 11 are different (as shown Fig. 9 As shown, hereinafter referred to as the left center of gravity regulator 11 and the right center of gravity regulator 11);

[0047] The overlap area of ​​the first valve port 16 and the second valve port 17 in the left center of gravity regulator 11 is small, and the airflow input from the left center of gravity regulator 11 to the first cylinder 7 is small, that is, the extension length of the first cylinder 7 is small (F2);

[0048] The overlap area of ​​the first air port 16 and the second air port 17 in the right center of gravity regulator 11 is large, and the air flow input from the right center of gravity regulator 11 to the second cylinder 8 is large, that is, the extension length of the second cylinder 8 is large (F1);

[0049] refer to Fig.10 , F2 is smaller than F1, at this time, the position of the cloth support 10 shifts to the right, that is, the center of gravity G1 of the load on the cloth support 10 shifts to G2 until it coincides with G2 (G2 is the center of gravity position when the traction machine is in a balanced state), so that the cloth support 10 can be lifted more stably. It should be noted that when the first cylinder 7 and the second cylinder 8 extend at different speeds, the cloth support 10 tensions the first cylinder 7, and the first cylinder 7 flips in the direction of F3, and the first electromagnetic telescopic pin 28 pushes the limit block 26 to move in the direction of F4 and compresses the reset spring 27, which also makes the center of gravity G1 of the load on the cloth support 10 shift to G2.

[0050] b. The center of gravity G3 of the load on the support cloth 10 is Figure 6 As an example, when the first cylinder 7 and the second cylinder 8 rotate to Figure 6When in the position shown, if the center of gravity G3 of the load on the support cloth 10 does not coincide with G2, refer to 7. Since the limit block 26 moves in the direction of F4 and compresses the return spring 27, the first cylinder 7 can continue to flip, and the overlapping area of ​​the first valve port 16 and the second valve port 17 in the left center of gravity adjuster 11 can continue to increase. At this time, the extension length of the first cylinder 7 is greater than the extension length of the second cylinder 8 (the principle is the same as above and will not be repeated here), and the position of the support cloth 10 shifts to the left, that is, the center of gravity G3 of the load on the support cloth 10 shifts to G2 until it coincides with G2.

[0051] It should be noted that when the support cloth 10 is separated from the bed body 1 and before the electromagnetically driven brake mechanism 31 is activated, the support cloth 10 is manually shaken and the swing amplitude of the support cloth 10 is observed to determine whether the standard of balanced lifting is achieved.

[0052] It should be emphasized that the first cylinder 7 rotates synchronously with the first turntable 25, and the second cylinder 8 rotates synchronously with the second turntable 21. Through the swing angle difference between the first cylinder 7 and the second cylinder 8, the center of gravity regulators 11 on the left and right sides are controlled to respectively deliver air flow to the first cylinder 7 and the second cylinder 8, thereby realizing the function of the center of gravity regulator 11 automatically adjusting the center of gravity position of the traction machine load, thereby achieving the effect of balanced lifting of the patient.

[0053] The traction machine proposed in the present invention is provided with a center of gravity adjuster 11. When the traction machine is used to lift the support cloth 10, the center of gravity adjuster 11 can be used to control the rotation angle and telescopic length of the first cylinder 7 and the second cylinder 8 in a linked manner, so that the center of gravity (G1 / G3) of the load on the support cloth 10 is offset toward the center of gravity (G2) of the traction machine. When the centers of gravity of the two coincide, the traction machine can lift the patient more stably, thereby solving the problem that in actual use, the patient's lying position is different, and the patient's position needs to be repeatedly adjusted to prevent unstable lifting, which results in a heavy workload.

[0054] Since the traction machine has the function of automatically adjusting the center of gravity during lifting, there is no need to enlarge the volume of the traction machine to increase its stability, so that the traction machine can be manufactured into a smaller volume, which is convenient for its placement and movement, and meets the use needs of public places such as wards.

[0055] The traction machine utilizes the telescopic action of the first cylinder 7 and the second cylinder 8 to lift the support cloth 10. The patient can lie on the support cloth 10 and be lifted up for transfer operation without being tied up, making the operation more convenient. In addition, by setting the first angle controller 12 and the second angle controller 13, the angles of the first cylinder 7 and the second cylinder 8 can be controlled respectively, so that the support cloth 10 is stretched into a certain arc state, so that the patient can maintain a comfortable lying posture, which greatly improves the convenience and comfort of its use.

[0056] The transfer bed is provided with traction machines clamped on both sides of the bed body 1. The traction machines have the function of traction-moving the bed body 1 and lifting the patient, providing convenience for the transfer of patients with limited mobility. The traction machine is designed to be separated from the bed body 1, and the traction machine can be placed at the tail end 1 of the bed body. When the traction machine is clamped in the middle area on both sides of the bed body 1, the radius of its turning movement is reduced, and it is more flexible and convenient to use.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
