Description

Technical Field

[0002] A crane refers to a multi-action lifting machinery that vertically lifts and horizontally moves heavy objects within a certain range. The crane trolley will have a certain inertia after stopping, and it is necessary to cooperate with the lateral limit structure to limit the crane trolley.

[0003] The existing technical authorization announcement number CN216662255U patent document provides a crane trolley limiting device. The crane trolley limiting device then has two springs providing rebound force to make the vertical plate and the cross bar elastic, buffer the force received, realize double spring support, prevent damage, and extend the service life. Then the thick plate drives the slide plate to the left and right sides of the top of the beam to adjust the limiting spacing of the crane trolley. It can be adjusted according to needs, which improves practicality. The bracket drives the brush to clean the top outer side of the beam to avoid dust from falling after a long period of non-use, ensuring the normal operation of the crane trolley limiting device and facilitating promotion.

[0004] However, when the existing crane lateral limit structure limits the trolley, it is not convenient to automatically monitor the force generated by the collision between the trolley and the contact surface of the limit structure, and it is not convenient for the staff to reserve a safe braking distance for the crane trolley according to the position of the limit structure. The traditional spring structure buffers the impact force on the collision surface of the crane trolley. Under the repeated compression of the spring, its elastic potential energy will fail, which is easy to cause certain wear and tear on the crane structure, directly affecting the safety and stability of the crane.
