The present invention can control the engagement or separation of the eccentric wheel with the side of the rail through an electric cylinder, that is, the eccentric wheel is separated from the rail during the traveling process of the carrier, so as to ensure that the carrier can operate normally, and the eccentric wheel is engaged with the rail during the process of connecting the goods, so that the annular groove on the circumference of the eccentric wheel is locked with the side of the rail, so that even if the center of gravity of the carrier is offset, the rollover of the carrier can be effectively prevented, and the goods on the carrier can be prevented from falling and causing damage to the goods, or even injuring the staff, thereby improving the safety of goods storage and retrieval.

Description

Technical Field

[0001] The invention relates to an anti-rollover mechanism for a rail carrier vehicle, belonging to the technical field of logistics equipment. Background Art

[0002] At present, in three-dimensional logistics warehouses, cargo transportation and storage are generally carried out by carriers. In the process of storing and retrieving cargo, the carriers move on the tracks of the three-dimensional logistics warehouse in a reciprocating or looping manner. However, when the carriers deliver cargo to designated cargo locations or connect cargo, some cargo is heavy, and the center of gravity of the carrier gradually deviates during the process of the cargo being moved by the telescopic pickup and delivery device on the carrier to or from the cargo location or elevator, which can easily cause the carrier to roll over, causing cargo to fall and be damaged, or even injuring workers, posing a major safety hazard. Summary of the invention

[0003] The purpose of the present invention is to provide a rollover prevention mechanism for a rail vehicle, which can effectively prevent the vehicle from rolling over, avoid the cargo on the vehicle from falling and causing damage to the cargo, or even injuring staff, thereby improving the safety of cargo storage and retrieval.

[0004] The technical solution of the present invention is as follows: a rollover prevention mechanism for a rail carrier vehicle comprises a rail and a carrier vehicle traveling on the rail, the carrier vehicle comprising a frame, a travel motor and travel wheels, two pairs of travel wheels are installed at the bottom of the frame, two travel motors are symmetrically installed at the rear of the frame, each travel motor is transmission-connected to the corresponding travel wheel through a transmission shaft, two pairs of bearing seats are symmetrically installed on both sides of the middle of the frame, a rotating shaft is rotatably connected to each bearing seat, an eccentric wheel is fixedly connected to the lower end of each rotating shaft, the eccentric wheel is meshed with the side of the rail, and a swing arm is fixedly connected to each rotating shaft, a connecting rod is arranged on one side of the swing arm, and two swing arms on the same side are respectively hinged to the two ends of the connecting rod, and an electric cylinder is fixedly installed at the front of the frame, and the telescopic rod of the electric cylinder is hinged to the end of the connecting rod.

[0005] Furthermore, an annular groove is provided on the circumference of the eccentric wheel, and the annular groove is engaged with the side surface of the track.

[0006] Furthermore, the bearing seats are arranged in pairs, a sleeve is fixedly connected to the middle of the rotating shaft, and the sleeve is located between the two bearing seats.

[0007] Due to the adoption of the above technical scheme, the advantage of the present invention is that the present invention can control the engagement or separation of the eccentric wheel and the side of the track through an electric cylinder, that is, the eccentric wheel is separated from the track during the movement of the carrier, thereby ensuring the normal operation of the carrier, and the eccentric wheel is engaged with the track during the process of connecting the goods, so that the annular groove on the circumference of the eccentric wheel is locked with the side of the track, so that even if the center of gravity of the carrier is offset, it can effectively prevent the carrier from rolling over, avoid the goods on the carrier from falling and causing damage to the goods, or even injuring the staff, thereby improving the safety of storing and retrieving the goods.

[0012] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0013] Embodiment of the present invention: A schematic diagram of a structure of a rollover prevention mechanism for a rail vehicle is shown in FIG. Figures 1 to 4As shown, it includes a track 9 and a carrier that travels on the track 9. The carrier includes a frame 1, a travel motor 8 and a travel wheel 10. Two pairs of travel wheels 10 are installed at the bottom of the frame 1, and two travel motors 8 are symmetrically installed at the rear of the frame 1. Each travel motor 8 is connected to the corresponding travel wheel 10 through a transmission shaft 2. Two pairs of bearing seats 5 are symmetrically installed on both sides of the middle of the frame 1. A rotating shaft 3 is rotatably connected to each bearing seat 5. An eccentric wheel 6 is fixedly connected to the lower end of each rotating shaft 3, and the eccentric wheel 6 is meshed with the side of the track 9. At the same time, a swing arm 11 is fixedly connected to each rotating shaft 3, and a connecting rod 4 is arranged on one side of the swing arm 11. The two swing arms 11 on the same side are hinged to the two ends of the connecting rod 4 respectively. An electric cylinder 7 is fixedly installed on the front of the frame 1, and the telescopic rod of the electric cylinder 7 is hinged to the end of the connecting rod 4. An annular groove is provided on the circumference of the eccentric wheel 6, and the annular groove meshes with the side of the track 9. The bearing seats 5 are arranged in pairs, and a sleeve 12 is fixedly connected to the middle of the rotating shaft 3, and the sleeve 12 is located between the two bearing seats 5. Therefore, when the eccentric wheel 6 is subjected to force, the axial force transmitted by the eccentric wheel 6 to the rotating shaft 3 is transmitted to the bearing seat 5 through the sleeve 12, thereby preventing the rotating shaft 3 from moving on the bearing seat 5 and improving its stability.

[0014] The present invention controls the engagement or separation of the eccentric wheel 6 and the side of the track 9 through the electric cylinder 7, that is, the eccentric wheel 6 is separated from the track 9 during the movement of the carrier, so as to ensure the normal operation of the carrier, and the eccentric wheel 6 is engaged with the track 9 during the process of connecting the goods, so that the annular groove on the circumference of the eccentric wheel 6 is locked with the side of the track 9. In this way, even if the center of gravity of the carrier is offset, it can effectively prevent the carrier from overturning, avoid the goods on the carrier from falling and causing damage to the goods, or even injuring the staff, thereby improving the safety of storing and retrieving the goods.
