Abstract

The utility model provides a container crane and a hanging tool weighing system thereof. The hanging tool weighing system comprises a weight sensor and a controller connected with the weight sensor, wherein the weight sensor is installed inside a locking pin of a hanging tool upper rack. The container crane and the hanging tool weighing system thereof enable axial force of the weight sensor to maintain on one direction throughout, can avoid data errors caused by unevenness of stress, and bring convenience to improving accuracy of the system.

Description

Container handling crane and suspender weighing system thereof

Technical field

The utility model relates to a kind of container handling crane and suspender weighing system thereof.

Background technology

At present, all have special weighing system usually in the container handling device, prevent the potential safety hazard that freight container causes owing to overload, unbalance loading in transit, for transporting safely of freight container provides safeguard.Existing weighing system in the prior art can reach 0.5% precision in theory, but surveys the value of out of reach nominal far away, and its major cause is exactly the mounting means of weight sensor.

Referring to figs. 1 to Fig. 4, in the prior art, pressure type sensor 11 is installed on the end of upper sling lock pin 10; Because the axial force direction of weight is inconsistent; Cause stressed inhomogeneous of pressure type sensor 11, must cause the deviation of data, this also is the one of the main reasons that causes its precision not high.

The utility model content

The technical matters that the utility model will solve provides a kind of container handling crane and suspender weighing system thereof, can improve weighing precision.

For solving the problems of the technologies described above, the utility model provides a kind of suspender weighing system of container handling crane, comprises weight sensor and coupled controller, and said weight sensor is installed in the lock pin of upper sling.

Alternatively, the lock pin end of said upper sling is provided with mounting hole, and said weight sensor is installed in the said mounting hole.

The utility model also provides a kind of container handling crane, comprises above each described suspender weighing system.

Compared with prior art, the utlity model has following advantage:

In the container handling crane of the utility model embodiment and the suspender weighing system thereof, the lock pin that weight sensor is installed on upper sling is inner, has kept the conformability of weight sensor axial force, and its precision can be reached in 5%.

Fig. 2 is the front elevation of Fig. 1;

Fig. 3 is the left view of Fig. 1;

Fig. 4 is the birds-eye view of Fig. 1;

Fig. 5 is the mounting structure scheme drawing of the weight sensor of the utility model embodiment.

The specific embodiment

Below in conjunction with specific embodiment and accompanying drawing the utility model is described further, but should limit the protection domain of the utility model with this.

With reference to figure 2, the suspender weighing system in the present embodiment comprises weight sensor 21 and coupled controller (not shown), and wherein, weight sensor 21 is installed in the lock pin 20 of upper sling.

Particularly, lock pin 20 ends of upper sling have mounting hole, and it is inner that weight sensor 21 is installed on this mounting hole, makes its axial force remain at a direction, have avoided the datum error that causes owing to discontinuity, have promoted system accuracy greatly.Utilize the precision of system to calculate, the trueness error of this weighing system can reach in 0.5%.

Present embodiment also provides a kind of container handling crane, comprises above-described suspender weighing system.Particularly, this container handling crane can comprise upper sling, be fixed on lock pin on the upper sling, be installed on this lock pin in-to-in weight sensor, the controller that links to each other with this weight sensor etc.

Though the utility model with preferred embodiment openly as above; But it is not to be used for limiting the utility model; Any those skilled in the art are in spirit that does not break away from the utility model and scope; Can make possible change and modification, so the protection domain of the utility model should be as the criterion with the scope that the utility model claim is defined.

Claims

1. the suspender weighing system of a container handling crane comprises weight sensor and coupled controller, it is characterized in that said weight sensor is installed in the lock pin of upper sling.

2. suspender weighing system according to claim 1 is characterized in that, the lock pin end of said upper sling is provided with mounting hole, and said weight sensor is installed in the said mounting hole.
