Description

Lifting mechanism

Technical Field

The utility model relates to a lifting mechanism.

Background

The existing X-type lifting mechanism is generally driven by a pushing cylinder assembly, the pushing cylinder assembly comprises a pushing cylinder body and a pushing rod, the pushing cylinder body is generally hinged on a base, the other end of the pushing cylinder body is hinged on one arm of an X arm, and in order to ensure that the bearing capacity of the pushing rod is enhanced, the following two methods are generally adopted:

1. the driving force arm is enlarged, at the moment, under the condition of bearing a certain mass, the required thrust of the push rod can be small, but in the structure, the push rod needs a longer structure, and the occupied space is larger

2. The sectional area of the push rod is increased, so that the strength of the push rod can be improved, the bearing capacity is increased, and the occupied space is larger due to the structure.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, the utility model provides a lifting mechanism which is realized by the following technical scheme.

The utility model relates to a lifting mechanism which comprises an upper frame, a base, an X adjusting lifting frame and a pushing cylinder assembly, wherein the X adjusting lifting frame comprises a first lifting arm and a second lifting arm, the pushing cylinder comprises a pushing cylinder body and a pushing rod assembly, the pushing cylinder assembly is fixed on the first lifting arm, the pushing cylinder body is used for driving a pushing rod to move along the length direction of the first lifting arm, the pushing rod is connected with the second lifting arm through a connecting rod, two ends of the connecting rod are respectively connected with the pushing rod and the second lifting arm in a rotating mode, and when the pushing rod moves, the connecting rod is used for realizing the opening or closing of the first lifting arm and the second lifting arm.

Further, the pushing cylinder is an electric pushing cylinder.

Furthermore, the connecting rod is connected with the pushing rod in a rotating mode through a transition sliding block, the first lifting arm is provided with a sliding groove, the transition sliding block is fixed to the pushing rod and can slide in the sliding groove, the transition sliding block is provided with a pin shaft, a pin shaft sliding hole is formed in the side wall of the sliding groove, and the pin shaft penetrates out of the pin shaft sliding hole and is connected with the connecting rod in a rotating mode.

The utility model has the beneficial effects that: compared with the prior art, the pushing cylinder body drives the pushing rod to move, so that the connecting rod is driven to move, the first lifting arm and the second lifting arm are unfolded or folded, and the upper frame is lifted or lowered. Compared with the prior art that the pushing cylinder body is arranged on the base, the lifting arm has the advantages that the required torque is smaller when the same weight is driven to lift, the pushing cylinder and the pushing rod are arranged on the lifting arm, the moving range of the pushing cylinder body is along the length direction of the lifting arm, the structure is compact, the size is small, the pushing cylinder and the pushing rod are arranged on a pipeline detection robot, the entering minimum pipe diameter is smaller, and the pipe diameter range capable of being detected is enlarged.
