Description

A multi-angle lifting machine

Technical field

The utility model relates to a jacking machine, in particular to a multi-angle jacking machine, which belongs to the field of electromechanical integration.

Background technique

The traditional jacking equipment is mainly a jack. Since the jack has only one degree of freedom in linear motion, it can only lift objects in a fixed direction after installation and cannot be adjusted in real time according to the situation being lifted. In this way, the direction of the lifting force of the jack is fixed. Adjust the lifting object to the expected position for jacking, and the lifting of a single pole is inherently unstable, and the structure of the work site is also unstable. When a force perpendicular to the direction of movement of the pole is slightly applied, it will lose stability and collapse.

Contents of the invention

The utility model provides a multi-angle jacking machine capable of jacking up at various angles, which solves the problem that the existing jacking device moves in a single direction and cannot adjust the jacking angle in real time during the jacking process, and can ensure the jacking The problem of the stability of the device itself.

A multi-angle jacking machine of the utility model includes a top support plate, a linear rod end bearing, a double-acting hydraulic rod, a base, a rotating pair, a bottom telescopic rod and a center seat. The center seat is the center of gravity, and the periphery of the center seat passes through The rotating pair connects the three bottom telescopic rods. In order to ensure the stability of the bottom, the angle between the adjacent bottom telescopic rods around the center seat is 120°. The other end of the bottom telescopic rod is connected to the inner side of the base through the rotating pair. The inner area of the base is larger than that of the bottom telescopic rod In this inner area, the upper side of the base is connected with the lower end of the double-acting hydraulic rod through a rotating pair. There are two upper and lower protrusions on the inner side of the double-acting hydraulic rod to connect with the two oil pipes of the electro-hydraulic control device respectively, and the upper end of the double-acting hydraulic rod is connected to At the lower end of the linear rod end bearing, the upper end of the linear rod end bearing is fixedly connected to the lower end of the top support plate.

The multi-degree jacking machine of the utility model, by placing the base, the bottom telescopic rod, and the center seat on the ground, controls the lifting of the double-acting hydraulic rod through the electro-hydraulic control device, and adjusts the jacking angle of the jacking object in real time. The lifted weight is turned over so that the weight enters the predetermined lifting posture and then lifted.

In order to ensure that the utility model is applicable on uneven ground, a through hole can be provided at the base 6, and the base 6 is fixed on the uneven ground with a steel cone.

In order to ensure that the utility model is applicable on slippery ground, a rubber pad can be installed under the through hole of the base 6 to prevent the jacking machine of the present invention from slipping.

Beneficial effect:

(1) Since the utility model has three double-acting hydraulic rods, the lifting movement of the double-acting hydraulic rods is controlled by the electro-hydraulic control device, so as to realize the multi-directional movement of the top support plate, multi-angle turning and timely lifting during the jacking. machine to control;

(2) Since the utility model takes the central seat as the center of gravity, the periphery of the central seat is connected with three bottom telescopic rods through a rotating pair, and the angle between the adjacent bottom telescopic rods around the central seat is 120°, which can ensure that the lifting machine itself stability.
