Description

Technical Field

[0001] The utility model relates to a door opening and closing device, in particular to a door opening and closing device used for a container turnover machine. Background Art

[0002] The container turning machine is used to lift the container and turn it over so that the box mouth faces upwards. After loading the bulk materials into the box mouth, the container is turned over in the opposite direction to be in a horizontal state and placed on the transport vehicle. When using the traditional container turning machine, the container door is mostly opened first and then turned over. After the container turning machine turns the container into place, it is necessary to climb up the container body with a ladder to assist in loading and closing the door. This method is less safe. Most existing container turning machines are equipped with automatic door closing devices. This device closes the container door by driving a push rod with a roller at the end through a piston. However, this device has the following problems. First, the contact part between the push rod and the container door is the roller, which cannot effectively fix the container door. During the closing process, the container door will detach from the closing device, and there is a safety hazard that the empty travel box door will fall instantly. Secondly, this door closing device can only close the container door. During the container turning process, the container door is in an open state, which poses a greater risk. Utility Model Content

[0020] like Figure 1-4As shown, a door opening and closing device for a container turning machine includes an electromagnet 1, a slide rail 3, a slider 4, and a transmission arm 5, wherein the electromagnet 1 is connected to one end of the slide rail 3 through an electromagnet bracket 2, and the electromagnet 1 is connected to the electromagnet bracket 2 through a pin shaft. The slide rail 3 is an I-shaped structure in which two parallel plates are connected to opposite sides of a vertical plate at both ends. Two sliders 4 are arranged on the slide rail 3, and each slider 4 also includes a connecting rod 41, a pulley 42, and a slider housing 43. The slider housing 43 has a cavity inside, the connecting rod 41 is located on one side of the slider housing 43, and the pulley 42 has two pairs of pulleys arranged on both sides of the inner wall of the slider housing 43. The cross-section of the slider housing 43 is a square hole type with an opening at one end. The vertical plate of the slide rail 3 passes through the opening on the slider housing 43, and the parallel plate at one end of the slide rail 3 passes through an internal cavity of the slider housing 43. The parallel plate passing through the slider housing 43 is located between the inner wall of the slider housing 43 and the pulley 42. When in use, the pulley 42 rolls on the parallel plates. Two pairs of limit plates 6 are also provided at both ends of the slide rail 3. In this embodiment, the limit plate 6 at one end of the electromagnet 1 is integral with the electromagnet bracket 2, and the limit plate 6 is perpendicular to the vertical plate of the slide rail 3. The transmission arm 5 is composed of a push arm 51 and a rotating arm 52, wherein the push arm 51 and the rotating arm 52 are arranged at an angle, the connecting rod 41 is fixed to the push arm 51 by bolts, and a connecting pin hole 54 is provided at the end of the rotating arm 52. The transmission arm 5 is connected to the container turning machine frame pin through the connecting pin hole 54, and the connecting pin hole 54 is also the rotation center of the transmission arm 5. The intersection of the push arm 51 and the rotating arm 52 is a piston connection end 53. The transmission arm 5 is driven and controlled by a hydraulic system, and the hydraulic cylinder is connected to the container turning machine frame through a pin shaft. The transmission arm 5 is connected to the transmission rod in the hydraulic cylinder through a pin shaft at the piston connection end 53.

[0021] When opening the door, the hydraulic device is operated, and the transmission rod in the hydraulic cylinder extends to make the transmission arm 5 rotate slowly, driving the electromagnet 1 to approach the container door. When the electromagnet 1 reaches the door position, the power is turned on to make it tightly adsorbed with the door. After the door is adsorbed, the hydraulic device is operated to make the transmission arm 5 rotate in the opposite direction, and the slide rail 3 also slides to open the door. During the rotation of the transmission arm 5, the electromagnet bracket 2 allows the electromagnet 1 to swing freely to ensure the adsorption effect of the electromagnet 1 and the door. After loading the materials, the above operation is repeated in reverse to close the door and disconnect the power supply of the electromagnet 1 to complete the operation of the entire process, thereby achieving the effect of safely opening and closing the door automatically.
