Embodiment 1

[0021] see Figure 1~3 , in an embodiment of the present invention, a dual-power servo hydraulic jacking device with an interlocking function includes a stabilizing plate 1, a vertical support 2 vertically fixed on the stabilizing plate 1, and a vertical support 2 parallel to the vertical support 2 The hydraulic cylinder 11 and the driving mechanism on the stable plate 1;

[0022] Specifically, the drive mechanism includes a hydraulic actuator assembly for pumping oil and a mechanical actuator assembly for rigid drive, wherein the top flange of the vertical support 2 is equipped with a servo motor 3 electrically connected to a power supply and a control switch. The output end of the motor 3 is connected to the worm 4, and the worm 4 is respectively connected to the hydraulic actuator and the mechanical actuator. It should be noted that since the servo motor 3 is controlled by the control switch, when the control switch is pressed forward, the servo motor 3 drives the worm scr...

Embodiment 2

[0025] In order to further describe the mechanical actuator components in the above-mentioned embodiments in detail, in another embodiment of the present invention, a dual-power servo hydraulic jacking device with interlocking function, the mechanical actuator components include fixed connections behind the worm gear 5 The gear 6 at the top, the rack 15 meshing with the gear 6, and the movable plate 16 fixed with the rack 15, wherein the upper end of the movable plate 16 is fixed on the upper part of the lifting rod 12, and the lower part of the movable plate 16 is fixed with a The slider 19 and the guide groove 7 are fixed on the outer wall of the hydraulic cylinder 11. When the worm gear 5 rotates, the gear 6 is driven to rotate. The gear 6 drives the rack 15 and the movable plate 16 to move, and the movable plate 16 drives the lifting rod 12 to move. The hydraulic oil realizes the double lifting of hydraulic machinery, and the lifting load range is wider. In addition, becaus...

Abstract

The invention discloses a dual-power servo hydraulic jacking device with an interlocking function. Particularly, hydraulic energy of oil drives a lifting rod to be lifted, a gear drives a rack and a movable plate to move to lift the lifting rod synchronously, the hydraulic and mechanical lifting effects are achieved, the load bearing load is large, the worm and gear transmission one-way self-locking function is used for achieving interlocking of the lifting rod, and the problem that an existing hydraulic lifting device is prone to happening falling risks when leakage happens is solved. A drivemechanism includes a hydraulic execution assembly for pumping oil and a mechanical execution assembly for rigid driving, wherein a vertical bracket top end flange is provided with a servo motor electrically connected to a power source and used for controlling a switch, the output end of the servo motor is connected to a worm, and the worm is connected with the hydraulic execution assembly and themechanical execution assembly.

Description

technical field [0001] The invention relates to a hydraulic power device, in particular to a dual-power servo hydraulic jacking device with an interlocking function. Background technique [0002] Jacking machinery is widely used in production, and most of the jacking devices adopt hydraulic jacking method; when the jacking operation starts, start the plunger pump, operate the jacking cylinder, adjust the cylinder piston rod connected to the jacking beam, and lift the beam Combined with the steps on the standard section, put the shaft heads at both ends of the jacking beam into the step grooves, disconnect the connection between the bearing seat and the tower body, and operate the jacking cylinder to slowly extend the piston rod of the cylinder out, slowly start to lift until the jacking support rod is above the steps, operate the oil cylinder to make the jacking support rod reliably snap into the groove of the steps, and after the overall stability of the jacking sleeve, ope...
