Abstract
The utility model relates to a cone pulley spring balance device of a medical X-ray machine, belonging to the technical field of medical devices. The cone pulley spring balance device structurally comprises a lifting steel wire rope guide pulley (1), a spring holder (2), a balance spring (3), a spring steel wire rope seat (4), a lifting steel wire rope (5), a spring steel wire rope (6), a cone pulley component (7), an X-ray combined machine head (8), an upright post component (9) and a lifting guide track (10), and is characterized in that when the X-ray combined machine head (8) is pulled up and down, the lifting steel wire rope (5) drives the cone pulley component (7) to rotate through the lifting steel wire rope guide pulley (1) to enable the spring steel wire rope (6) to pull the balance spring (3), and the elastic force change produced by expansion and contraction of the balance spring (3) is converted to a constant pulling force through the cone pulley component (7) to enable the X-ray combined machine head (8) to be in a balanced state in any position. The cone pulley spring balance device has the advantages of light weight, compact structure, low manufacturing cost, safety, reliability and convenience in operation.
Description
Technical field
The invention belongs to technical field of medical instruments.
Background technology
Existing X-ray production apparatus lifting balance device adopts following two kinds of modes usually: 1, balance piece balance X ray mono-tank, due to the balance piece, whole weight of equipment is increased, and raise because the balance piece makes center of gravity, so stabilization of equipment performance is poor; 2, use Spring balancer balance X ray mono-tank, because the Spring balancer volume is excessive, and planform is irregular, and medical X ray machine volume and limited space, so bring very large difficulty to structural design, even can't use the Spring balancer balance.
Summary of the invention
The design's goal of the invention is: overcome the defect that above-mentioned bascule brings, it is effective combination of a kind of cone pulley and spring, utilize the variable force produced in the spring drawing process, the conical surface by cone pulley is converted to constant force, carry out balance X ray mono-tank, thereby machine weight is light, compact conformation, low cost of manufacture, safe and reliable, easy to operate.
The design invents and solves the technical scheme that its technical problem adopts and be: this device is by the lifting wire rope guide wheel, spring fixed seat, balancing spring, spring steel wire rope seat, lifting wire rope, the spring steel wire rope, the cone pulley assembly forms, it is characterized in that: riser guide is fixed on columns assemblies, the X ray mono-tank can move up and down along riser guide, balancing spring is fixed on columns assemblies by spring fixed seat, the spring steel wire rope is connected with lifting wire rope with balancing spring respectively, when pulling up and down the X ray mono-tank, lifting wire rope is by the lifting wire rope guide wheel, driving the cone pulley assembly rotates, make the spring steel wire rope pull balancing spring, the flexible force variation produced of balancing spring changes a constant pulling force into by the cone pulley assembly, make the X ray mono-tank in any position all in poised state.
The design's beneficial effect of the invention is: at medical X ray machine particularly on the Medical movable X-ray production apparatus, the X ray mono-tank moved up and down is very heavy, move up and down stroke large, the columns assemblies space is very little, utilize balancing spring processing diameter little, the characteristics that length is long, can effectively utilize the column useful space, be combined into the cone pulley spring equalizing device with the cone pulley assembly and carry out balance X ray mono-tank, only when mounting equipment, once adjust the equilibrant of balancing spring, this cone pulley spring equalizing device compact conformation, lightweight, easy for installation, cost is low, the advantage such as easy to maintenance, working effect is remarkable, safe and reliable.
The accompanying drawing explanation
Fig. 1 is example structure schematic diagram of the present invention.
In figure, 1, the lifting wire rope guide wheel; 2, spring fixed seat; 3, balancing spring; 4, spring steel wire rope seat; 5, lifting wire rope; 6, spring steel wire rope; 7, cone pulley assembly; 8, X ray mono-tank; 9, columns assemblies; 10, riser guide.
The specific embodiment
With reference to accompanying drawing, its structure is by lifting wire rope guide wheel (1), spring fixed seat (2), balancing spring (3), spring steel wire rope seat (4), lifting wire rope (5), spring steel wire rope (6), cone pulley assembly (7), X ray mono-tank (8), columns assemblies (9), riser guide (10) forms, it is characterized in that: riser guide (10) is fixed on columns assemblies (9), X ray mono-tank (8) can move up and down along riser guide (10), balancing spring (3) is fixed on columns assemblies (9) by spring fixed seat (2), spring steel wire rope (6) is connected with lifting wire rope (5) with balancing spring (3) respectively, when pulling up and down X ray mono-tank (8), lifting wire rope (5) is by lifting wire rope guide wheel (1), driving cone pulley assembly (7) rotates, make spring steel wire rope (6) pull balancing spring (3), the flexible force variation produced of balancing spring (3) changes a constant pulling force into by cone pulley assembly (7), make X ray mono-tank (8) in any position all in poised state.
When the assembling bascule, make the X ray mono-tank be placed in the most significant end of riser guide, the initial position of lifting wire rope is at the minimum diameter end of cone pulley assembly, adjust the length of spring steel wire rope, make balancing spring start to produce pretension, the pulling force that balancing spring produces can balance X ray mono-tank, and till while making on the X ray mono-tank that lower pulling force equates substantially.
Its advantage is: machine weight is light, compact conformation, and low cost of manufacture, safe and reliable, easy to operate.
