Description

Technical Field

[0001] The utility model relates to the technical field of cargo weighing, in particular to a shuttle weighing alarm system. Background Art

[0002] In logistics transportation, shuttles are a common means of transportation used to move goods quickly and efficiently within a warehouse. However, during the transportation of goods, the weight of the goods may be incorrect or the goods may fall, which brings certain challenges and troubles to the logistics transportation process. This situation may result in inconsistent supply or the need for rework, which in turn wastes time and human resources. It is difficult to monitor the status of the goods in a timely manner during the logistics transportation process. When the above situation occurs, it is usually discovered after the goods arrive at the destination, which makes it difficult to handle. Therefore, in order to achieve efficient and accurate point-to-point transportation, a system is needed that can monitor the correct weight of the goods in real time and issue an alarm when a problem is found. Utility Model Content

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the problem that the shuttle vehicle in the prior art cannot monitor the weight of the goods in real time, and thus cannot promptly discover the situation where the quantity of goods is incorrect, and cannot issue an alarm when the goods are wrong.

[0006] As an improvement of the above scheme, the control device also includes a numerical comparator, which is communicatively connected to a sound and light alarm. The numerical comparator stores a standard cargo weight. The cargo weight obtained by the pressure sensor is compared with the pre-stored standard cargo weight. If the two do not match, the sound and light alarm sounds an alarm.

[0007] As an improvement of the above solution, the driving member is a telescopic electric cylinder, the top end of the electric cylinder is connected to the lifting frame, and the bottom end of the electric cylinder is connected to the chassis.

[0008] As an improvement of the above solution, the slide rail is obliquely arranged on the inner side surface of the chassis, and the roller moves obliquely upward or downward along the slide rail.

[0009] As an improvement of the above scheme, the lifting frame includes a rectangular frame, the pressure sensor is installed above the four corners of the rectangular frame, the sliding assembly is installed below the four corners of the rectangular frame, an intermediate rod is connected to the middle of the rectangular frame, the intermediate rod is arranged parallel to one side of the rectangular frame, the top end of the electric cylinder is connected to the intermediate rod, and the bottom end of the electric cylinder is connected to the chassis.

[0010] As an improvement of the above solution, the electric cylinder is vertically arranged to the intermediate rod, and the electric cylinder is parallelly arranged to the slide rail.

[0011] As an improvement of the above solution, a flap is formed in the middle of the cargo pallet.

[0012] As an improvement of the above solution, a handle is provided on the flip cover.

[0013] As an improvement of the above solution, wheels are arranged below the chassis.

[0014] The technical solution of the utility model has the following advantages:

[0015] The utility model provides a shuttle weighing alarm system, in which a driving part drives a lifting frame to rise, so that the weight of the goods on the cargo pallet is all supported by a pressure sensor, the weight of the goods is obtained by the pressure sensor, and then a numerical comparator is used to judge whether the current weight of the goods meets the standard, and if it does not meet the standard, an audible and visual alarm will sound an alarm in time. The application has a simple structure and is easy to operate. It can monitor the weight of the goods in real time, find out the wrong quantity of the goods in time, improve the transportation efficiency, and avoid wasting time and human resources.

[0032] The lifting frame 3 includes a rectangular frame 31, the pressure sensor 5 is installed above the four corners of the rectangular frame 31, and the sliding assembly is installed below the four corners of the rectangular frame 31. An intermediate rod 32 is connected to the middle of the rectangular frame 31, and the intermediate rod 32 is arranged parallel to one side of the rectangular frame 31. The top end of the electric cylinder 4 is connected to the intermediate rod 32, and the bottom end thereof is connected to the chassis 1. The electric cylinder 4 is arranged vertically to the intermediate rod 32, and the slide rail 7 is arranged parallel to the electric cylinder 4, which makes it easier to drive the lifting frame 3 to move up and down.
