Problems solved by technology

The above two types of existing engineering vehicles realize the twistlock function by receiving the lock state signal from the spreader, the driver operates the handle to give the twistlock solenoid valve signal, and controls the action of the hydraulic twistlock cylinder. In actual work, if The driver's operation is not standardized enough, frequent and rough operation of the handle will shorten the service life of the handle and hydraulic twist lock cylinder, and also increase the labor intensity of the driver

Embodiment 1

[0035] Such as image 3 As shown, a control method for automatic locking of a container spreader, comprising the following steps:

[0036] (1) Collect the signals detected by the loading sensor, unlocking sensor and locking sensor installed at the lock head of the spreader, and then judge the current state parameters of the lock head of the spreader according to the following table; among them, the loading sensor, unlocking sensor And the lock sensor is represented by "1" when the signal is detected, and "0" when the signal is not detected:

[0037] Check-in signal unlock signal lock signal Lock state of spreader 0 0 0 failure or power failure 0 0 1 Normal (locked) state 0 1 0 Normal (idle or unlocked) state 0 1 1 Fault 1 0 0 Malfunction or working during locking or unlocking 1 0 1 Normal (packed and locked) condition 1 1 0 Normal (boxed and unlocked) state 1 1 1 Fault

[0038] (2) According to...

Embodiment 2

[0047] like Figure 1-3 As shown, a control system of a control method for automatic locking of a container spreader, including a vehicle controller 2, and a spreader lock head 9 and a twist lock cylinder 8 installed on a spreader 1, the spreader 1 The lock sensor 4, the unlock sensor 5 for detecting the lock head 9 of the spreader, and the box sensor 6 for detecting the contact between the spreader and the container are respectively installed on the top; the lock sensor 4, unlock sensor 5, box The signal output ends of the sensors 6 are all connected with the vehicle controller 2; the oil inlet end of the twist lock oil cylinder 8 is communicated with the output end of the hydraulic oil pump on the vehicle through a solenoid valve, and the output ends of the vehicle controller 2 are connected with the vehicle controller 2 respectively. The solenoid valve and the vehicle instrument 3 are electrically connected.

[0048] In a further scheme, the bottom end of the output end of...

Abstract

The invention discloses an automatic locking control method for container lifting appliance box landing. The control method comprises the following steps that the current state parameters of a liftingappliance lock head is collected; whether the state of the lifting appliance lock head is normal is judged, and whether the state of the lifting appliance lock head is in an unlocking state is judged; the lifting appliance lock head is placed in a lock hole of a corresponding container, a box landing signal is detected, an electromagnetic valve oil path is opened, hydraulic oil enters a rotary locking oil cylinder to lock the lifting appliance lock head and the container automatically; and an locking signal is detected, the electromagnetic valve is closed, and a lifting action or a lock headunlocking action is carried out. A control system of the automatic locking control method for container lifting appliance box landing is further provided. By monitoring the state of the lifting appliance lock head in real time, the lifting appliance lock head is locked automatically, the labor intensity of a driver can be effectively reduced, the service life of an operation handle and a hydraulicoil cylinder can be prolonged, and the reliability and the working efficiency of a whole vehicle can be improved.

Description

technical field [0001] The invention relates to the technical field of mechanical control, in particular to a control system and a control method for automatic locking of a container spreader when placed in a container. Background technique [0002] Construction vehicles using container spreaders mainly include container reach stackers and empty container stackers, both of which belong to the handling construction machinery and are mainly used to carry heavy or empty containers. The hoisting and stacking of them in the handling operation is mainly realized by the spreader at the front of the vehicle. The connection between the container and the spreader is to connect the two as a whole through the lock head of the spreader entering the container lock hole and then rotating, so as to realize the lifting of the container by the vehicle. The above two types of existing engineering vehicles realize the twistlock function by receiving the lock state signal from the spreader, the...
