Detailed implementation manners

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] This specific embodiment is only an interpretation of the present invention and is not a limitation thereof. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the Patent Law.

[0023] Embodiment: As Figure 1 , Figure 2 and Figure 3 shown, a four-way vehicle layer-changing elevator includes a frame 1, a lifting frame 2 disposed in the frame 1 through a guiding mechanism 4, and a lifting mechanism 3 for driving the lifting frame 2 to lift and lower. It also includes two groups of conveying assemblies 5 spaced apart on the lifting frame 2 and two support tracks 6 disposed on the opposite side of the two groups of conveying assemblies 5. The height difference between the conveying surface of the conveying assembly 5 and the supporting surface of the support track 6 is greater than the height of the four-way vehicle. Among them, the conveying assembly 5 adopts a conventional synchronous belt conveyor, and the support track 6 is fixed on the conveying frame inside the synchronous belt conveyor.

[0024] As Figure 2As shown in the figure, the cross-section of the support rail 6 has an L-shaped structure. At the front and rear ends of the support rail 6, movable blocking mechanisms 7 are respectively provided. The movable blocking mechanism 7 includes a fixed frame 701 fixed below the support rail 6, a guiding rail 410 provided on the fixed frame 701, a moving member 704 slidably mounted on the guiding rail, a blocking plate 702 hinged at one end to the support rail 6, a support rod 703 connecting the blocking plate 702 and the moving member 704, and an actuating element 705 for driving the movement of the moving member 704. The moving member 704 is a slider or a roller and is movably installed at the end of the support rod 703. The actuating element 705 is a cylinder or an electric push rod, and the actuating element 705 is fixedly installed on the fixed frame 701. An installation opening 602 is provided on the support rail 6, and the blocking plate 702 is hinged within the installation opening 602.

[0025] At both ends of the support rail 6, transition plates 601 that slope downward are provided, and the inclination angle is 10 - 20°, which facilitates the four-way vehicle to enter the support rail 6.

[0026] When the four-way vehicle enters and exits the lifting frame 2, the blocking plate 702 is in a horizontal state and flush with the support surface of the support rail 6; when the four-way vehicle completely enters the lifting frame 2, the two outer ends of the blocking plate 702 swing upward, making the blocking plate 702 in an inclined state, which plays a role in limiting the four-way vehicle front and back. When the four-way vehicle transports goods and needs to change floors, when entering the lifting frame 2, first use the lifting mechanism of the four-way vehicle itself to lift the goods, making the goods higher than the conveying surface of the conveying assembly 5; after entering the lifting frame 2, then lower to temporarily store the goods on the conveying assembly 5 where the width of the goods is greater than the spacing between the two conveying assemblies 5, facilitating the four-way vehicle to adjust its position.

[0027] The lifting mechanism 3 adopts a conventional sprocket and chain mechanism, with two sets in number, and is provided on both sides of the frame 1. The lifting mechanism 3 includes a driving shaft provided at the lower end of the frame 1, a driven shaft provided at the upper end of the frame 1, two driving sprockets provided on the driving shaft and the driven shaft, a driving chain connecting the two driving sprockets, and a motor for driving the rotation of the main shaft. The lifting frame 2 is connected to the driving chain.

The guiding wheels are on three sides of the guiding rail 410. The guiding mechanism 4 has two sets in number, and is respectively arranged on the left and right sides of the lifting frame 2.

[0029] The guide wheels include a first guide wheel 402, a second guide wheel 403, and a third guide wheel 404. The first guide wheel 402 and the third guide wheel 404 are respectively arranged on both sides of the guide track 410 relatively. The first guide wheel 402 is installed on the guide frame 401. The guide frame 401 is further provided with a first adjustment component and a second adjustment component. The third guide wheel 404 is arranged on the first adjustment component, and the second guide wheel 403 is arranged on the second adjustment component.

[0030] The first adjustment component includes a movable mounting plate 405 slidably mounted on the guide frame 401, an adjustment seat 406 arranged at the end of the movable mounting plate 405, and a first adjustment screw 407 screwed on the adjustment seat 406 and with its end abutted against the movable mounting plate 405. The third guide wheel 404 is installed on the movable mounting plate 405. The clearance of the third guide wheel 404 on the front and rear sides of the guide track 410 can be adjusted through the first adjustment component to prevent the lifting frame 2 from shaking too much in the front and rear directions.

[0031] The second adjustment component includes fixed seats 408 respectively arranged on both sides of the second guide wheel 403, adjustment long slots arranged on the fixed seats 408, and a second adjustment screw 409 screwed on the fixed seats 408. The two ends of the rotating shaft of the second guide wheel 403 are arranged in the adjustment long slots. The end of the second adjustment screw 409 extends into the adjustment long slot and abuts against the rotating shaft of the second guide wheel 403. The clearance of the two second guide wheels 403 on the left and right sides of the guide track 410 can be adjusted through the second adjustment component to prevent the lifting frame 2 from shaking too much in the left and right directions.

[0032] As Figure 4 shown, a buffer mechanism 8 is arranged at the lower end of the frame 1. The buffer mechanism 8 is respectively arranged at the front and rear ends of the conveying component 5. The buffer mechanism includes a buffer seat 801, a hydraulic cavity 802 arranged in the buffer seat 801, a first hydraulic channel 803 vertically arranged at both ends of the buffer seat 801 and communicating with the hydraulic cavity 802, a first piston 804 arranged in the first hydraulic channel 803, a second hydraulic channel 805 arranged between the two first hydraulic channels 803 and communicating with the hydraulic cavity 802, a second piston 806 arranged in the second hydraulic channel 805, and an elastic buffer member connected to the second piston 806. A support column 201 for supporting on the first piston 804 is arranged at the bottom of the lifting frame 2.

[0033] The elastic buffer member includes a buffer guide rod 810 connected to the second piston 806, a guide mounting block 809 installed at the outlet of the second hydraulic channel 805, and a buffer spring 808 connected between the guide mounting block 809 and the second piston 806.

[0034] At the opening of the first hydraulic passage 803, there are two guiding plates 807 distributed in a horn shape. The two guiding plates 807 are distributed front and back along the conveying direction of the conveying assembly 5. On the support column 201, there is a fourth guiding wheel 202. The rotation center of the fourth guiding wheel 202 coincides with the center line of the support column 201, and the lowest point of the fourth guiding wheel 202 is located above the lower end of the support column 201. When the lifting frame 2 is offset during the descending process, the fourth guiding wheel 202 rolls downward along the guiding plate 807, enabling the support column 201 to accurately contact the first piston 804 below, thereby playing a buffering role.
