Abstract
The invention discloses a cone pulley and spring balance device of a medical X ray machine, and belongs to the technical field of medical instruments. The cone pulley and spring balance device structurally consists of a lifting steel wire rope guide wheel (1), a spring fixing seat (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 head (8), a stand column component (9) and a lifting guide rail (10), and is characterized in that the lifting steel wire rope (5) drives the cone pulley component (7) to rotate through the lifting steel wire rope guide wheel (1) when the X ray combined head (8) is pulled up and down, so that the spring steel wire rope (6) pulls the balance spring (3); the change of elastic force produced by extension and retraction of the balance spring (3) is converted into constant tension through the cone pulley component (7), so that the X ray combined head (8) is in a balance state at any position. The cone pulley and spring balance device has the advantages of light machine 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 block balancing x-ray mono-tank, due to balance block, whole weight of equipment is increased, and center of gravity is raised, so stabilization of equipment performance is poor due to balance block; 2, Spring balancer balancing x-ray mono-tank is used, because 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, Spring balancer even cannot be used to balance.
Summary of the invention
The design's goal of the invention is: overcome the defect that above-mentioned bascule brings, it is the efficient combination of a kind of cone pulley and spring, utilize the variable force produced in spring elongation process, be converted to constant force by the conical surface of cone pulley, carry out balancing x-ray mono-tank, thus 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 adopts of its technical problem and be: this device is made up of lifting wire rope guide wheel, spring fixed seat, balancing spring, spring steel wire rope seat, lifting wire rope, spring steel wire rope, cone pulley assembly, it is characterized in that:
Riser guide is fixed in columns assemblies, X-ray combination head can move up and down along riser guide, balancing spring is fixed in columns assemblies by spring fixed seat, spring steel wire rope is connected with balancing spring and lifting wire rope respectively, when pulling X-ray combination head up and down, lifting wire rope is by lifting wire rope guide wheel, cone pulley assembly is driven to rotate, spring steel wire rope is made to pull balancing spring, balancing spring produced force variation of stretching changes a constant pulling force into by cone pulley assembly, makes X-ray combination head all be in poised state in any position.
The design's beneficial effect of the invention is: on medical X ray machine particularly Medical movable X-ray production apparatus, the X-ray combination head moved up and down is very heavy, move up and down stroke large, columns assemblies space is very little, balancing spring is utilized to process diameter little, the feature that length is long, can effectively utilize the column useful space, be combined into cone pulley spring equalizing device with cone pulley assembly and carry out balancing x-ray mono-tank, the equilibrant of balancing spring is only once adjusted when mounting equipment, 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.
Accompanying drawing explanation
Fig. 1 is embodiments of the invention structural representations.
In figure, 1, 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 combination head; 9, columns assemblies; 10, riser guide.
Detailed description of the invention
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 combination head (8), columns assemblies (9), riser guide (10) forms, it is characterized in that: riser guide (10) is fixed in columns assemblies (9), X-ray combination head (8) can move up and down along riser guide (10), balancing spring (3) is fixed in columns assemblies (9) by spring fixed seat (2), spring steel wire rope (6) is connected with balancing spring (3) and lifting wire rope (5) respectively, when pulling X-ray combination head (8) up and down, lifting wire rope (5) is by lifting wire rope guide wheel (1), cone pulley assembly (7) is driven to rotate, spring steel wire rope (6) is made to pull balancing spring (3), the flexible force variation produced of balancing spring (3) changes a constant pulling force into by cone pulley assembly (7), X-ray combination head (8) is made all to be in poised state in any position.
When assembling bascule, X-ray combination head is made to 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, the length of adjustment spring steel wire rope, balancing spring is made to start to produce pretension, the pulling force that balancing spring produces can balancing x-ray mono-tank, and when making that on X-ray combination head, lower pulling force is substantially equal till.
Its advantage is: machine weight is light, compact conformation, and low cost of manufacture is safe and reliable, easy to operate.
