Description

Technical Field

[0001] The utility model belongs to the technical field of containers, and particularly relates to a container turnover device with a protection function. Background Art

[0002] The container turnover machine is used for the transfer and loading and unloading of various granular bulk materials such as grain, plastic, iron filings, and ore powder, and is applicable to places such as railway freight yards, docks, mines, grain depots, and coal yards. The container turnover machine is convenient to operate, fast in loading, and low in operation cost. It only requires one person to operate, which saves a lot of manpower.

[0003] However, at present, insufficient attention is paid to the safety protection problem of the container turnover machine, and there are the following problems: 1. At present, when the container turnover machine is operating, there are no warning or protection measures for the on-site and surrounding personnel, and it is easy to cause safety accidents if people enter by mistake; 2. At present, a vertical ladder is fixed on the sliding frame of the container turnover machine. After each container is loaded, the personnel who open and close the box door need to climb along the vertical ladder to the top platform of the sliding frame to close the box door, and then return to the ground along the vertical ladder. If the operator accidentally touches or the support platform turns and shakes during the whole process, the personnel who open and close the box door are easy to fall and get injured.

[0042] Before loading, the two railings 42 are in the raised state, and vehicles loaded with empty containers can freely pass through the middle of the two fixed fences 3. The vehicle moves the empty container to the lower part of the container tilter 1 and loads it through the container tilter 1. During the loading operation, the fence lifting controller 43 controls the two railings 42 to fall. The two fixed fences 3 and the two railings 42 form a closed rectangle for hard isolation protection to prevent personnel from straying in and causing safety accidents. At the same time, it is set that only when the two railings 42 fall in place, the fence lifting controller 43 will send a start signal to the tilter electric control box 2, and the tilter electric control box 2 controls the movement of the container tilter 1 for loading, thereby further ensuring the protection effect.

[0043] In a specific embodiment, an infrared sensor 5 is provided on the fixed fence 3, and the infrared sensor 5 is electrically connected to the tilter electric control box 2. When a person strays in, the infrared sensor 5 alarms, and the tilter electric control box 2 controls the container tilter 1 to stop running, further ensuring the protection effect.

[0044] In a specific embodiment, displacement sensors 6 are respectively provided at both inner ends of the other fixed fence 3, and the two displacement sensors 6 at both ends are respectively electrically connected to the fence lifting controller 43. The displacement sensors 6 are used to detect whether the railings 42 have fallen in place. When they have fallen in place, the displacement sensors 6 send signals to the fence lifting controller 43, and the fence lifting controller 43 then sends a start signal to the tilter electric control box 2.

[0045] In a specific embodiment, the container tilter 1 includes two lower brackets 11, two lifting columns 12, two upper brackets 13, a support platform 14, a sliding frame 15, and two telescopic rods 16;

[0047] A fastener for connecting with a container is provided at the bottom of the sliding frame 15 for fixing with the container. The left and right movement of the container is controlled by the sliding of the sliding frame 15 on the support platform 14. The height of the upper support frame 13 is controlled by the lifting of the lifting column 12, so as to control the height of the sliding frame 15, and further control the height of the container. The flipping of the support platform 14 is controlled by the telescopic movement of the two telescopic rods 16, so as to control the flipping of the sliding frame 15, and further control the flipping of the container. In this embodiment, the lifting column 12 is a hydraulic telescopic cylinder, the telescopic rod 16 is a hydraulic cylinder rod, the lower support frame 11 is a regular triangular frame structure, and the upper support frame 13 is an inverted triangular frame structure.
