Problems solved by technology

[0003] The original detection methods cannot meet the needs of the operation
First, the detection of the track scale and the special over-balanced load detector at the cargo inspection station is an after-the-fact detection. The container has been loaded on the train. If the over-balanced load is found, it needs to be adjusted at the nearest loading and unloading operation point, which will affect the efficiency of railway transportation.
These devices are huge in structure and expensive in construction, and are not suitable for loading yards with a large number of different conditions; second, truck scales, crane scales, hook scales, etc. can only detect container overload, but cannot detect unbalanced loads

Embodiment 1

[0058] figure 1 It is a structural schematic diagram of a hoist equipped with a container overload and unbalanced load detection system device according to the present invention.

[0059] see figure 1 , during the container 6 loading process, the container loading position utilizes the positioning vertical bar 4 on the spreader beam 2 of the reach stacker 1, and the contact distance positioning with the open car compartment plate 8 outer wall of the open car 7 of the railway. Before the loading operation, insert the positioning rod fixing pins 9 on the first and second positioning rod cross bars into the pin holes at both ends of the spreader beam 2 of the reach stacker 1; then insert the locks at the four corners of the basic beam Align the lock holes on the top four corners of the container 6 to be shipped and lock them, and after lifting to a certain height, adjust the vehicle to figure 1 The position and angle shown are facing the gondola car 7 parked on the railway line...

Embodiment 2

[0090] On the basis of embodiment 1, this embodiment 2 provides a working method of the hoist.

[0091] The hoisting machine includes: a spreader beam, wherein

[0092] The spreader beam is provided with a detection device for collecting container eccentric load data,

[0093] The detection device is connected with a computer terminal;

[0094] The computer terminal is adapted to calculate the partial load value of the container currently being lifted by the spreader beam according to the partial load data of the container.

[0095]Further, the spreader beam includes: a telescopic spreader in the middle, a spreader upper frame located at the upper end of the telescopic spreader, pulley blocks distributed at the four corners of the spreader upper frame, and each pulley block corresponds to a lifting wire rope to be fixed to the lifting frame. and the telescopic spreader is respectively connected to four turnlock boxes through corresponding fixed rods; and the detection device...

Abstract

The invention relates to a lifting machine suitable for detecting an eccentric load value of a container and a working method thereof; the lifting machine comprises a spreader beam, wherein the spreader beam is provided with a detecting device for collecting the eccentric load data of the container; the detecting device is connected to a computer terminal; the computer terminal is suitable for calculating an eccentric load value of the current hoisted container of the spreader beam according to the eccentric load data of the container; the lifting machine provided by the invention realizes theinstant measurement, is convenient for direct processing, and saves a lot of manpower and material cost; by using the cooperation technology of a laser and a sensor, the measurement is faster, the detection is more accurate, and the safety is improved. Meanwhile, the two threshold determination methods, in the case of ensuring rapid measurement of the laser mode, use a further dual camera matching measurement method for suspected dangerous situations between the micro-eccentric load and the super-eccentric load; therefore the measurement accuracy is improved and the safety is further improved.

Description

technical field [0001] The invention belongs to the technical field of unbalanced load and unbalanced load detection, in particular to a hoist suitable for detecting the unbalanced load value of a container and its working method. Background technique [0002] Container transportation is the development direction of modern logistics industry. In recent years, container transportation has entered a period of rapid development, and the proportion of container transportation in my country's railway freight has increased year by year. However, the phenomenon of overloading and eccentric loading in container transportation has a certain impact on safe transportation. Once the container is overloaded and unbalanced, when it is loaded on the train, the center of gravity of the loaded vehicle will deviate beyond the limit in the horizontal or vertical direction, which will cause safety hazards and even cause serious accidents such as train derailment or rollover. In order to ensur...
