Detailed Description
The present invention will be further described with reference to the following specific examples.
The invention provides a screw rod waist bridge jacking linkage device, which comprises a waist bridge 1, a handle 2, a torsion transmission shaft 3, a first driving assembly 4 and a second driving assembly 5, wherein the first driving assembly 4 comprises a first multistage screw rod 6 and a first power assembly 7, the first power assembly 7 is connected with the first multistage screw rod 6, the second driving assembly 5 comprises a second multistage screw rod 9 and a second power assembly 8, and the second power assembly 8 is connected with the second multistage screw rod 9; wherein first multistage screw rod 6 and second multistage screw rod 9 all include first screw rod 10, second screw rod 11 and third screw rod 12 that have coaxial line screw thread muff-coupling in order, during second screw rod 11 inserted first screw rod 10, during third screw rod 12 inserted second screw rod 11, the internal thread of first screw rod 10 closes with the external screw thread of second screw rod 11 soon, and second screw rod 11 external screw thread closes with the external screw thread of third screw rod 12 soon, and first screw rod 10 is the outermost screw rod of multistage screw rod, and third screw rod 12 is the innermost screw rod. The first screw 10, the second screw 11 and the third screw 12 are all trapezoidal threads and have the same thread pitch.
The two sides of the torque force transmission shaft 3 are respectively connected with one sides of a first power assembly 7 and a second power assembly 8, a handle 2 is arranged on the side face of the second power assembly 8, and the waist bridge 1 is fixed above the first multistage screw rod 6 and the second multistage screw rod 7. Wherein, the material of the torsion transmission shaft 3 is carbon fiber material which can transmit X-ray.
The first power assembly 7 and the second power assembly 8 comprise a first bevel gear 13, a second bevel gear 14, a gear chain assembly 15 and an input shaft 16, one end of the input shaft 16 passes through the bottom of a fixing member 17 to be connected with the first bevel gear 14, the other end of the input shaft 16 extends to the outside of the fixing member 17, two ends of the torsion transmission shaft 3 respectively pass through the side surface of the fixing member 17, the two ends of the torsion transmission shaft 3 are respectively provided with the second bevel gear 14, the first bevel gear 13 and the second bevel gear 14 are vertically engaged and connected,
the other end of the input shaft 16 of the second power assembly 8 is connected with the handle 2,
the lower part of the input shaft of the first power assembly 7 is connected with the first screw rod through a gear chain assembly, and the lower part of the input shaft 16 of the second power assembly 8 is connected with the first screw rod 10 through a gear chain assembly 15.
When the waist bridge plate needs to be lifted, the handle connected with the second driving assembly is rotated, power is transmitted to the first screw rod through the gear chain, and the first screw rod, the second screw rod and the third screw rod form two-stage screw rods to drive the waist bridge plate to lift. Meanwhile, vertical rotation is converted into horizontal rotation through the meshed first bevel gear and the meshed second bevel gear, and power is transmitted to the driving assembly (namely the first driving assembly) on the other side through the torsion transmission shaft, so that the waist bridge plates are lifted, and the waist bridge plates on two sides are lifted simultaneously.
