Description

Hydraulic locking pin device

Technical Field

The utility model relates to a hydraulic pressure latch device belongs to hydraulic mechanical equipment technical field.

Background

When the wind generating set is maintained and overhauled, the wind wheel must be locked, and safety accidents caused by rotation of the wind wheel are prevented. At present, wind wheel locking devices adopted on wind generating sets are mostly mechanical manual locking devices, operation is troublesome, and failure rate is high.

Technical indexes such as the structure, the installation position and the like of the existing hydraulic drive lock pin device are customized for a specific wind generating set, and the universality is not strong; in addition, when the locking pin device is in failure, the disassembly process is complex and laborious; the problem that the locking pin is stuck and cannot be pushed for a long time due to the lack of effective lubrication in the advancing and retreating sliding process of the locking pin, poor durability and high failure rate.

Disclosure of Invention

An object of the utility model is to overcome the aforesaid not enough, provide a simple structure, dismantle convenient, the commonality strong, from the hydraulic pressure lockpin device of taking lubricated effect.

The purpose of the utility model is realized like this:

a hydraulic latch device characterized by: the hydraulic lock pin device comprises a lock pin, a guide sleeve, an oil cylinder bracket and a displacement sensor; the left end of the guide sleeve is provided with a connecting bolt hole, and the right end of the guide sleeve is provided with an oil cylinder bracket; a sensor bracket is arranged in the oil cylinder bracket; the displacement sensor is arranged on the sensor bracket; the lock pin is embedded in the guide sleeve in a sliding manner, a lock pin annular frame is arranged at the right end of the lock pin, and the lock pin annular frame is hinged with a piston rod of the oil cylinder through a pin shaft; the fixed end of the oil cylinder is hinged with the oil cylinder bracket through a pin shaft;

the utility model relates to a hydraulic locking pin device, the inner wall of the guide sleeve in sliding contact with the locking pin is provided with a graphite block with self-lubricating function;

the utility model relates to a hydraulic locking pin device, two sets of displacement sensors are installed on a sensor bracket; the displacement sensor is a proximity switch;

when the wind wheel locking and unlocking device works, the oil cylinder pushes out or retracts the lock pin to control the wind wheel to be locked and unlocked, the two sets of displacement sensors monitor the working stroke of the lock pin in real time to determine the locking or unlocking state, and the locking or unlocking state has an interlocking function, and if the lock pin is not inserted in place, the next action cannot be executed; the graphite blocks on the inner wall of the guide sleeve have good self-lubricating effect, so that the stability and reliability of long-term use are ensured; the outer diameter of the guide sleeve can be adjusted according to the difference of the installation positions of the locking structure so as to adapt to different wind generating sets; when the locking pin device needs to be maintained or replaced, only the connecting bolt of the guide sleeve needs to be loosened.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses simple structure, installation are dismantled conveniently, from the area lubrication, the fault rate is low, can adapt to multiple wind generating set's locking mechanical system.
