Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic excavator accessories, specifically a hydraulic excavator safety lock device. Background Technology

[0002] The safety lock on a wheeled hydraulic excavator, as the name suggests, is designed with the operator's safety in mind. Since the excavator's movements are hydraulically driven, the safety lock can promptly control this hydraulic transmission. After the excavator starts, the operator, seated in the seat, should turn the hydraulic safety lock to the unlocked position. Only then will the excavator move accordingly when operating the control handle or travel pedals. When the excavator is not in operation or when the operator wants to leave the machine, the hydraulic safety lock should also be turned to the locked position to prevent accidents caused by accidental contact with the control handles or travel pedals.

[0003] However, when the excavator is in use by the operator, if the operator is not working or wants to get off the machine, and forgets to turn the hydraulic safety lock to the locked position, the operator may accidentally touch the handle and travel pedal, causing a safety accident. The overall safety and protection are low, and there are safety hazards.

[0004] Therefore, this utility model provides a safety lock device for hydraulic excavators to solve the above problems. Utility Model Content

The unlocking rod is lowered to unlock, and the safety lock is lowered to unlock, so that the safety lock is locked when the person leaves, thereby improving safety. The mounting slots facilitate the installation of the seat.

[0011] As a preferred technical solution of this application, a cap is fixedly connected to the top of the unlocking rod, and an iron block is fixedly connected to the bottom of the cap. The cap can increase the force-bearing surface, making it easier for personnel to apply force for control and adjustment.

[0012] As a preferred technical solution of this application, a magnetic ring is fixedly connected to the top of the fixed frame, and the unlocking rod passes through the magnetic ring. When the unlocking rod slides down, the iron block and the magnetic ring come into contact, further improving the locking effect of the safety lock.

[0013] Compared with the prior art, the beneficial effects of this utility model are: During use, the convenient components allow drivers to simultaneously lock and unlock the hydraulic system after fastening their seatbelts. When the driver leaves the vehicle, the seatbelt can be unlocked and the safety lock can be engaged simultaneously, preventing drivers from forgetting to use the system and improving convenience and safety.
