Description

Technical Field

[0001] The utility model relates to the field of lifting and hoisting equipment, and more specifically, to a mobile scissor lift for hoisting. Background Art

[0002] As is well known, there are many styles of mobile scissor lifts, which are generally used in environments where the complexity is not high and can only work within a straight-up-and-down range. If a mobile scissor lift needs to bear a large lateral load at high altitude, ordinary mobile scissor lifts cannot adapt to such working environments. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a mobile scissor lift for hoisting, which solves the problem that the scissor lift cannot hoist heavy objects laterally at high altitude.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a mobile scissor lift for hoisting, provided with a chassis frame, an electric rear axle is fixed below the chassis frame, and the drive wheels are connected to the electric rear axle. Its characteristics are that a wire rope tensioning mechanism is installed on the chassis frame, and four stable support legs are connected to the chassis frame through pin shafts; the chassis frame is hinged to the lower part of the lifting arm through a pin shaft, the movable end of the lifting arm is hinged to the lower slider through a pin shaft, and the lower slider can slide in the slideway of the chassis frame. Both ends of the electric push rod are hinged to the lifting arm, the fixed end above the lifting arm is hinged to the manned frame through a pin shaft, the movable end of the upper part of the lifting arm is hinged to the upper slider through a pin shaft, and the upper slider can slide in the slideway of the manned frame. The lifting small hoist is fixed on the manned frame; four wire ropes extend from the wire rope tensioning mechanism on the chassis frame, one end of each of the four wire ropes is fixed on the wire rope tensioning mechanism, and the other end of each of the four wire ropes is fixed on the four corners of the manned frame.

[0005] The other ends of the four wire ropes are respectively fixed on the four corners of the manned frame after passing through the guide wheels on the four stable support legs.

[0006] The beneficial effect of the utility model is that it realizes the hoisting of heavy objects on the side at high altitude by the mobile scissor lift, and has the characteristics of simple operation, safety and reliability, and good stability. Brief Description of the Drawings

[0012] In the figure, the electric rear axle 1 of the present utility model is fixed below the chassis frame 3, the driving wheel 2 is key-connected to the electric rear axle 1, the wire rope tensioning mechanism 8 is installed on the right side of the chassis frame 3, and the four stabilizing outriggers 10 are connected to the chassis frame 3 through pin shafts and can swing within a certain angle; the fixed end below the lifting arm 4 is hinged to the chassis frame 3 through a pin shaft, the movable end of the lifting arm 4 is hinged to the lower slider through a pin shaft, and the lower slider can slide in the slideway of the chassis frame 3. The two ends of the electric push rod 5 are hinged to the lifting arm 4. The fixed end above the lifting arm 4 is hinged to the lower part of the passenger-carrying frame 6 through a pin shaft, and the movable end of the upper part of the lifting arm 4 is hinged to the upper slider through a pin shaft, and the upper slider can slide in the slideway of the passenger-carrying frame 6. The small hoist for lifting 7 is fixed to the upper part of the passenger-carrying frame 6 by bolts; the wire rope tensioning mechanism 8 on the chassis frame 3 extends four wire ropes 9. One ends of the four wire ropes 9 are fixed to the wire rope tensioning mechanism 8, and the other ends of the four wire ropes 9 respectively pass through the guide wheels on the four stabilizing outriggers 10 and are fixed to the four corners of the passenger-carrying frame 6. The wire rope tensioning mechanism 8 can control the wire ropes 9 to stretch and contract as the passenger-carrying frame 6 rises and falls. Under the action of the tension of the four wire ropes 9, the problem that the scissor lift cannot lift heavy objects laterally at high altitude can be effectively solved.
