Description

Intelligence driving hoist

Technical Field

The utility model relates to a driving hoist technical field, more specifically say, relate to an intelligence driving hoist.

Background

Along with the continuous development of intellectualization, the unmanned intelligent crane is also popularized rapidly, many enterprises are upgrading and transforming the unmanned intelligent crane, the intelligent crane utilizes sensing and computer technology, and cooperates with a warehouse management system to realize the unmanned operation of product offline, warehousing, online and loading, the unmanned crane has the advantages of reducing personnel, improving efficiency, improving safety and the like, is adopted by more and more enterprises, is used more in steel enterprises, and particularly is used for warehousing and transportation of steel coils.

The warehouse management system can manage the position of the warehouse according to the information of warehousing, moving and leaving of the traveling crane, under the normal condition, the information in the real object and the system is required to be completely consistent, otherwise, the information of warehousing and leaving is inconsistent with the information of the real object, the information of warehousing and leaving is disordered, and the condition that the warehouse checking is required to be carried out is generated. The network connection to the intelligent storage area is interrupted, the articles are moved artificially, and the product offline stations are staggered, so that the abnormal situation that the information of the articles and the storage positions is inconsistent can occur, when the system display on a certain storage position is empty, and actually, when one article exists, an unmanned vehicle can hoist the other article to the storage position which is considered to be empty by the system, at this time, the danger can occur, the other article can smash the article, the phenomenon of a steel mill can cause great loss every time, and the situation can occur in many intelligent storage areas, so that no good solution exists at present.

When unmanned driving is down transferring article, belong to the blind and put, all judge the height of article apart from ground according to the encoder on control wire rope's the motor, fall fast earlier, slow down put when calculating the height to ground soon, if adorn the camera on the driving, because the sheltering from of article on the hoist, still can not see below whether have article.

Therefore, the problem that unmanned intelligent vehicle driving has is that the position of the storage can only be judged according to the inventory information, when the suspended object is placed downwards, whether a person or an object is below the suspended object cannot be judged, if the person or the object is below the suspended object, the suspended object can be knocked up, and great loss or safety accidents are caused.

Fig. 1 is an overall structure diagram of the present invention.

In the figure: 1. a suspension arm; 2. a first horizontal photosensor; 3. a vertical photosensor; 4. a ranging sensor; 5. a pressure sensor; 6. a second horizontal photoelectric sensor; 7. a hanger main beam; 8. a motor; 9. a hook head; 10. a protective sliding plate.

Detailed Description

The invention is further described with reference to the following figures and examples:

example 1

As can be seen from fig. 1, the intelligent crane spreader of this embodiment is a fixture for lifting a steel coil, and includes a spreader main beam 7 and a boom 1, a hook 9 of an L-shape is disposed at a lower end of the boom 1, a motor 8 for driving the boom 1 to open and close is disposed on the spreader main beam 7, a lead screw is disposed in the spreader main beam 7, the motor 8 and the lead screw are connected through a transmission mechanism, the lead screw is connected with the boom 1, a downward-inclined distance measuring sensor 4 is disposed at an outer side of a base angle of the boom 1, the distance measuring sensor 4 is preferably an ultrasonic distance measuring instrument or a laser distance measuring instrument, the distance measuring sensor 4 can detect a distance from the base angle of the spreader to the ground or an object on the ground downward, and a cosine value obtained by multiplying the distance by an inclination angle is a height from the spreader to the ground or an upper surface of the object on the ground.

The first horizontal photoelectric sensor 2 is arranged below the inner side of the suspension arm 1 and close to the hook head 9, the second horizontal photoelectric sensor 6 is arranged below the hook head 9, after the first horizontal photoelectric sensor 2 and the second horizontal photoelectric sensor 6 are shielded and switched on once, the hook head 9 is explained to enter the position of the inner center of the steel coil, the steel coil can be clamped, the suspension arm 1 is driven by the motor 8 to clamp the steel coil inwards, the vertical photoelectric sensor 3 is arranged on the inner side of the suspension arm 1, the broken line in the figure represents the detection light of the photoelectric sensor, when the light of the vertical photoelectric sensor 3 of the detection light is shielded, the steel coil is explained to clamp the steel coil, the motor stops, the suspension arm stops tightening, and the steel coil can be lifted.

The 9 upper surfaces of gib head are equipped with pressure sensor 5 for whether detect the object and hoist, whether fall to the ground, when hoisting the object, pressure sensor 5 can give the system with object weight transmission, and when the object that hoists fallen to the ground, pressure sensor 5 can show that gravity is zero, and assistance system judges whether article have fallen to the ground, makes hoist and mount process automation intelligent.

The inner side of the suspension arm 1 is provided with a protective sliding plate 10 which can move up and down, and the upper end of the protective sliding plate 10 is lifted by a spring.

The inclination angle between the distance measuring sensor 4 and the vertical direction is 15-30 degrees, preferably 20 degrees, because when the hanger is used for downwards placing articles, articles are arranged on the lifting hook, if the articles are arranged below the articles, the articles are downwards detected from one end or two ends of the lower part of the hanger in an inclined mode, and then whether the articles are arranged under the hanger can be detected.

When highly being 3 meters when the range finding, range finding sensor 4 can be followed the both ends of article on the lifting hook and is being inclined downwards and detect the difference in height under the lifting hook and ground to judge the below and have article, solved the problem that facial make-up camera all can't solve.

The utility model discloses a theory of operation is: the intelligent traveling crane can be controlled by a computer, the operation of the traveling crane and the grabbing and moving of articles are instructed by the warehousing system WMS, the unmanned operation is realized, when the inventory information is wrong, articles may be on the warehouse location, and in order to avoid the crane from dropping down by placing another article, the lifting appliance of the utility model can play a role, when the crane lifts the article to the upper part of the warehouse location, when the crane is about to be lowered, the height of the lifting appliance is detected by the distance measuring sensor 4, the height is compared with the height calculated by the travelling crane encoder, if the heights are basically the same, indicating that no article is below, the falling can be normally carried out, if the detected height is smaller than the height calculated by the encoder, indicating that the article is below, the falling is immediately stopped, and an alarm is given, then, the intelligent driving can be automatically operated more safely by checking and verifying the intelligent driving on site manually to ensure that the objects below are not damaged.

The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
