Description

Mobile hydraulic lift table

technical field

The utility model relates to a hydraulic lifting device.

Background technique

In the field of electric power construction, it is often necessary to lift some equipment to the required height. It is very laborious to rely on manual work, and the required height cannot be maintained for a long time. When using the existing lifts, some need electricity, and the power construction is often in the field and cannot provide electricity. The hydraulic lifting platform needs the engine to provide power to drive the hydraulic cylinder to rise or fall. However, the height of the lift is not easy to control, and the height needs to be constantly adjusted during operation. The current lifting platform cannot meet the requirements of electric power construction.

Detailed ways

As shown in Figure 1, the utility model mobile hydraulic lifting platform comprises a base 1, the bottom of the base 1 is connected with a wheel 2, and the right side of the base 1 is connected with a handrail 3.

The wheel 2 near the handrail 3 side is a universal wheel, the universal wheel is provided with a foot brake 4, and the upper part of the base 1 is hinged with a folding lifting platform, and the folding lifting platform includes a folding frame 5 and is hinged on the top of the folding frame 5. The platform 6 of the base 1 and the bottom left end of the folding frame 5 are vertically provided with a first rotating shaft 7, the bottom left end of the base 1 and the folding frame 5 is hinged, the right half of the base 1 is horizontally provided with a raceway 8, and the folding frame 5 The right end of the bottom is connected with a roller 9, and the roller 9 is rollingly connected with the raceway 8; the first connecting rod 10 is fixedly connected to the first rotating shaft 7, and the bottom on the right side of the base 1 is longitudinally provided with a second rotating shaft 11, and the right side of the second rotating shaft 11 A pedal rod 13 is connected, and a second connecting rod 12 is also connected on the second rotating shaft 11. A hydraulic cylinder 14, a hydraulic cylinder seat 15, a drive rod 16 and a hydraulic cylinder 14 are sequentially connected between the first connecting rod 7 and the second connecting rod 12. The spring 17 sleeved on the driving rod 16, the hydraulic cylinder 14 and the driving rod 16 are respectively connected to both sides of the hydraulic cylinder base 15, and the two ends of the spring 17 are fixed between the hydraulic cylinder base 15 and the left end of the second connecting rod 12 .
