Referring to fig. 2 to 6, the counterweight device of the mobile X-ray photographing apparatus provided in this embodiment mainly includes: the winding and unwinding mechanism 100, the elastic mechanism 200 and the traction rope 300.
The winding and unwinding mechanism 100 is provided with a spiral winding portion 101, a direction from one end of the spiral winding portion 101 to the other end of the spiral winding portion 101 is a direction indicated by a horizontal solid arrow shown in fig. 5 and 6, and a radius of the spiral winding portion 101 increases gradually and decreases gradually in sequence from one end of the spiral winding portion 101 to the other end of the spiral winding portion.
The elastic mechanism 200 has a fixed end F and a movable end S, the fixed end F is in a fixed state, the movable end S is in a movable state, and the movable end S compresses the elastic mechanism 200 from the movable end S to the fixed end F, so that the elastic mechanism 200 is in a compressed state to store elastic potential energy. The fixed end F is located below the winding and unwinding mechanism 100.
The traction cable 300 can be wound on the spiral winding part 101 along the spiral direction of the spiral winding part 101, the traction cable 300 has a first end 301 and a second end 302, and the winding and unwinding mechanism 100 can wind or unwind the first end 301 and the second end 302 on the spiral winding part 101, in this embodiment, the first end 301 of the traction cable 300 is connected to the moving end S of the elastic mechanism 200, and the second end 302 of the traction cable 300 is used for connecting the lifting block 30 of the mobile X-ray photographing device.
In this embodiment, during the process of compressing the elastic mechanism 200 from the moving end S to the fixed end F, the elastic potential energy stored in the elastic mechanism 200 along with the deformation of the elastic mechanism 200 is relatively changed, so that the elastic force received by the first end 301 is changed, the elastic force received by the first end 301 is defined as an elastic force F1, the lifting block 30 connected to the second end 302 receives the weight from the lifting block and the telescopic cross arm 40 and the handpiece 50, the force received by the second end 302 is kept constant, and the constant force received by the second end 302 is defined as a lifting force F2. Since the spring force F1 changes during the raising and lowering of the hoist trolley 30, the first end 301 of the traction cable 300 changes relatively around the first winding radius R1 provided on the helical winding 101, and correspondingly the second end 302 of the traction cable 300 changes relatively around the second winding radius R2 provided on the helical winding 101. The first winding radius R1 is an unwinding radius of the first end 301 unwinding from the spiral winding portion 101 during the ascending process of the lifting pulley 30, and a winding radius of the first end 301 winding on the spiral winding portion 101 during the descending process of the lifting pulley 30, and the second winding radius R2 is a winding radius of the second end 302 winding on the spiral winding portion 101 during the ascending process of the lifting pulley 30, and an unwinding radius of the first end 301 unwinding from the spiral winding portion 101 during the descending process of the lifting pulley 30. According to the principle of moment balance, the product of the elastic force F1 and the first winding radius R1 is equal to the product of the lifting force F2 and the second winding radius R2. Of course, the product of the elastic force F1 and the first winding radius R1 and the product of the lifting force F2 and the second winding radius R2 may be substantially the same, allowing for a certain error range.

Fig. 6 shows a schematic view of the traction cable 300 being wound around the helical winding 101 when the lifting block 30 has reached the lowest point, the first winding radius R1 being smaller than the second winding radius R2. In the process that the lifting tackle 30 descends from the highest point to the lowest point, the first winding radius R1 is gradually reduced, the second winding radius R2 is gradually increased, and on the contrary, in the process that the lifting tackle 30 ascends from the lowest point to the highest point, the first winding radius R1 is gradually increased, and the second winding radius R2 is gradually reduced.

During the ascending process of the lifting block 30, the elastic mechanism 200 releases the elastic potential energy, the first end 301 of the traction cable 300 is unwound from the spiral winding portion 101, the unwinding radius is gradually increased, and the second end 302 of the traction cable 300 is wound on the spiral winding portion 101, and the winding radius is gradually decreased. That is, during the ascending of the lifting block 30, the first end 301 is unwound from the spiral winding portion 101, the first winding radius R1 is gradually increased, the second end 302 is wound on the spiral winding portion 101, and the second winding radius R2 is gradually decreased.
During the ascending process of the lifting tackle 30, under the premise that the lifting force F2 is kept unchanged, the second winding radius R2 is gradually reduced, and the first winding radius R1 is gradually increased, the elastic force F1 is gradually reduced. During the descending process of the lifting tackle 30, under the premise that the lifting force F2 is kept unchanged, the second winding radius R2 is gradually increased, and the first winding radius R1 is gradually reduced, the elastic force F1 is gradually increased.
