Description
Technical Field
The invention relates to the technical field of supporting devices and brackets, in particular to a double-scissor type hand-operated synchronous lifting bracket.
Background
When the helicopter tail section is in butt joint, the tail section needs to be lifted to the height of a straight machine body, the height difference is about 1500mm, the screw rod lifting mechanism is adopted to limit more and the multipoint lifting operation is difficult, and the electric scissor type lifting is not flexible enough.
Disclosure of Invention
The purpose of the invention is as follows: the invention aims to jack up the tail section to the butt joint height when the tail section of the helicopter is in butt joint with the fuselage, and in actual working conditions, the tail section needs to be lifted from 1.5 meters to about 3 meters, the jack-up stroke is very large, and meanwhile, the tail section needs to be stably adjusted step by step to align with an assembly mounting hole during butt joint, so that a bracket which can be stably lifted and has a large stroke is needed.
The technical scheme is as follows: the double-scissor type hand-operated synchronous lifting bracket comprises a left scissor lifting device, a right scissor lifting device, a supporting seat and a synchronous driving mechanism;
the left scissor lifting device and the right scissor lifting device are symmetrically arranged on the supporting seat;
the synchronous driving mechanism comprises four pull rods, a forward-rotation thread sleeve, a backward-rotation thread sleeve, a screw rod and a hand wheel; the screw rod is rotatably arranged on the supporting seat, threads with opposite turning directions are formed from the middle part of the screw rod to two ends of the screw rod, the threads with the opposite turning directions are respectively matched with the forward-turning thread sleeve and the backward-turning thread sleeve, and the forward-turning thread sleeve and the backward-turning thread sleeve can be driven to move oppositely or move back to back by rotating the screw rod; the positive rotation thread bush is respectively connected with the left scissor lifting device and the right scissor lifting device through two pull rods, the negative rotation thread bush is respectively connected with the left scissor lifting device and the right scissor lifting device through the other two pull rods, and the four pull rods are positioned in the same plane,
when the forward-rotation threaded sleeve and the backward-rotation threaded sleeve move oppositely or reversely, the left scissor lifting device and the right scissor lifting device can be driven by the pull rod to synchronously lift and link.
Furthermore, when the forward-rotation thread sleeve and the backward-rotation thread sleeve both move to the middle of the screw rod, the four pull rods form an X shape.
Furthermore, when the forward-rotation thread sleeve and the backward-rotation thread sleeve respectively move to two ends of the screw rod, the four pull rods form a diamond shape.
The technical effects are as follows: the double-shear fork lifting mechanism meets the stroke requirement of the assembly working condition, and the synchronous driving mode is adopted to ensure that the bracket is stably lifted and conveniently adjusted, so that the working requirement is fully met.

FIG. 2 is a top view of the present invention;
FIG. 3 is a schematic view of the present invention after being raised;
wherein: 1-left scissor lifting device, 2-right scissor lifting device, 3-support seat, 4-pull rod, 5-forward thread sleeve, 6-backward thread sleeve, 7-lead screw and 8-hand wheel.
Detailed Description
The following specific embodiments are given in conjunction with the accompanying drawings
The double-scissor type hand-operated synchronous lifting bracket comprises a power supply, a controller, a heating head, a first temperature sensor and a second temperature sensor; the power supply supplies power to the heating head; the first temperature sensor is used for detecting the temperature of the heating head, the second temperature sensor is used for detecting the temperature of the lug, and the first temperature sensor and the second temperature sensor send the detected temperature value to the controller; the controller controls the on-off of the power supply according to the temperature values detected by the first temperature sensor and the second temperature sensor.
Also comprises a heat insulation sleeve; the heating head comprises a hollow shell, a lead, a heating element and a copper plug; the lead, the heating element and the copper plug are all fixed in the hollow shell, the heating element is fixed inside the copper plug and penetrates out of the copper plug to be electrically connected with the lead, and an insulating material is arranged between the lead and the copper plug; the copper plug is matched with the lug hole and can be inserted into the lug hole for fixing; the heat insulation sleeve is used for coating the copper plug and the lug, so that heat is condensed and is not dissipated.
