[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] like Figures 1-14 As shown, the vertical lifting machine of the present invention includes a frame 1, a lifting component 2 installed in the middle of the frame 1, a fixed height structure 3 provided on the frame 1, a connecting structure 4 connected to the fixed height structure 3, an installation structure 5 connected between the frame 1 and the fixed height structure 3, a supporting structure 6 connected to the fixed height structure 3, a movable structure 7 provided on the bottom side of the frame 1, and a stabilizing structure 8 connected to the movable structure 7.

[0037] Specifically, the height-fixing structure 3 includes a positioning rod 304. The positioning rod 304 is located on the inner side of the frame 1. A first horizontal bar 301 is vertically arranged on one side of the frame 1. Insertion rods 302 are vertically fixedly connected to both ends of the first horizontal bar 301. A fitting strip 307 is provided on the side of the insertion rod 302, which engages with the positioning rod 304. A second horizontal bar 303 is vertically arranged at the end of the insertion rod 302. A fixing groove 308 is opened on the side of the frame 1. A first positioning block 305 is slidably connected to the end of the first horizontal bar 301. A first spring 306 is fixedly connected between the first positioning block 305 and the first horizontal bar 301. The end of the first positioning block 305 has a hemispherical structure, and the spherical end of the first positioning block 305 abuts against the frame 1 through the fixing groove 308. The height-fixing structure 3 allows for adjustment of the height of different layers of partitions as needed, making it more flexible. Specifically, in actual storage environments, it may be necessary to adjust the height of partitions in different layers as needed. In situations where goods need to be stored and retrieved at different heights, to facilitate the storage and retrieval of goods, the grid structure located on the frame 1, consisting of a first horizontal bar 301, a second horizontal bar 303, and a connecting rod 302, can be adjusted in height as needed. Using a positioning latch 304 located inside the frame 1, the fitting strip 307 on the connecting rod 302 located on the side of the first horizontal bar 301 can be engaged with a suitable notch on the side of the positioning latch 304 as needed. This determines the positions of the first horizontal bar 301 and the connecting rod 302. After the first horizontal bar 301 is in position, the first positioning block 305 on its inner side will abut against the fixing groove 308 on the frame 1, thus providing a certain positioning effect for the first horizontal bar 301, facilitating the subsequent installation of the second horizontal bar 303 and the connecting rod 302. Since the height of the first horizontal bar 301 and the second horizontal bar 303 can be changed depending on the fixed position between the connecting rod 302 and the positioning latch 304, the effect of adjusting the height of different layers of the grid can be achieved as needed.

[0038] Specifically, the connecting structure 4 includes a screw 402, the end of the plug rod 302 is fixedly connected to the screw 402, the end of the second crossbar 303 is slidably connected to a threaded sleeve 401, a first limiting groove 405 is provided on the inner side of the second crossbar 303, the threaded sleeve 401 is threadedly connected to the screw 402, a contact washer 403 is sleeved on the threaded sleeve 401, the contact washer 403 is slidably connected to the second crossbar 303 through the first limiting groove 405, and a second spring 404 is fixedly connected between the contact washer 403 and the second crossbar 303; the connecting structure 4 allows for quick... The frame is quickly fixed by: after determining the position of the first crossbar 301, the second crossbar 303 is placed at the end of the plug rod 302 where the screw 402 is located. The screw 402 is inserted into the hole at the end of the second crossbar 303 so that it abuts against the threaded sleeve 401 in the first limiting groove 405. Through the pushing effect of the abutment washer 403 and the second spring 404, the user only needs to rotate the threaded sleeve 401 to complete the threaded connection between the threaded sleeve 401 and the screw 402. After the threaded sleeves 401 on both sides are fixed to the corresponding screws 402, the frame installation is completed.

[0039] Specifically, the installation structure 5 includes a second limiting groove 503. The positioning rod 304 is slidably connected to the frame 1. The second limiting groove 503 is provided on the side of the positioning rod 304. A contact block 508 is slidably connected to the bottom part of the frame 1. A third spring 509 is fixedly connected between the contact block 508 and the frame 1. The contact block 508 abuts against the positioning rod 304 through the second limiting groove 503. A synchronizing rod 502 is rotatably connected to the inner side of the positioning rod 304. The shapes of the two ends of the synchronizing rod 502 match each other. A control lever 501 is rotatably connected to the bottom end of the frame 1. A drive rod 504 is fixedly connected to the middle part of the control lever 501. The drive rod 504 and the synchronizing rod 509 are rotatably connected to the bottom part of the frame 1. The ends of the step rods 502 engage with each other. Multiple positioning slots 507 are provided on the inner side of the frame 1. A top slider 505 is slidably connected to the top side of the frame 1. A positioning block 506 is rotatably connected to the middle of the top slider 505. The bottom end of the positioning block 506 engages with the end of the adjacent synchronizer rod 502. The side of the positioning block 506 engages with the frame 1 through the positioning slots 507. The installation structure 5 allows users to easily install different layers of gratings on the ground. Because warehouses are typically high, to facilitate grating installation, the positioning rods 304 located inside the frame 1 can be removed or inserted from the bottom side of the frame 1. The height of the first positioning rod 304 on the bottom side of the frame 1... Only the abutment block 508 is provided, which facilitates the removal of the positioning rod 304 while also positioning the installed positioning rod 304. After the installation of the first positioning rod 304 and the corresponding first crossbar 301 and second crossbar 303 is completed, in order to facilitate the installation of the subsequent grid, the user can directly lift the installed positioning rod 304 and the grid structure by the height of one positioning rod 304, and then continue to insert the next positioning rod 304 into the inner side of the frame 1, while ensuring that the synchronous rod 502 in the middle of the two positioning rods 304 is engaged. For the topmost positioning rod 304, the synchronous rod 502 is engaged with the end of the positioning rotating block 506 in the middle of the top sliding block 505. After installation, since the distance between the positioning slots 507 on the inner side of the frame 1 is the distance of one positioning rod 304, after all the positioning rods 304 are installed, and the end of the synchronizing rod 502 in the last positioning rod 304 is engaged with the end of the driving rod 504 in the control block 501, the user can rotate the control block 501. Through the synchronizing rods 502 connected at the beginning and end in the middle, the positioning rotating block 506 inside the top slider 505 can rotate and engage with the positioning slot 507 in the corresponding position. At this time, the installation and fixing of all positioning rods 304 can be completed. At the same time, the installation of the grid structure can also be completed during the installation of the positioning rods 304 without lifting the position.

[0040] Specifically, the receiving structure 6 includes a support rod 608. The inner sides of both the first crossbar 301 and the second crossbar 303 are rotatably connected to the support rod 608. A toothed ring 609 is fixedly connected to the side of the support rod 608. A sliding rod 604 is provided on the side of the toothed ring 609. A toothed groove 607 is formed on the side of the sliding rod 604. The sliding rod 604 meshes with the toothed ring 609 through the toothed groove 607. A fourth spring 606 is fixedly connected between the sliding rod 604 and the first crossbar 301. A pull rod 601 is fixedly connected to the side of the sliding rod 604. A locking rod 602 is rotatably connected to the side of the first crossbar 301. A torsion spring 603 is fixedly connected between the locking rod 602 and the first crossbar 301. A locking groove 605 is formed on the side of the sliding rod 604 adjacent to the locking rod 602. The receiving structure 6 can... To provide protection during equipment maintenance, in the event of a malfunction in the lifting component 2, support rods 608 are provided on the inner sides of the first crossbar 301 and the second crossbar 303 on each floor to ensure safety during maintenance. Users can pull the side lever 601 to make the slide rod 604 slide and drive the toothed ring 609 to rotate through the toothed groove 607. At this time, the support rod 608 can be rotated out from the side of the first crossbar 301 and the second crossbar 303 to provide support and protection for the lifting component 2 being maintained above, preventing the equipment from falling and causing danger or loss. When it is necessary to retract the support rod 608, the user only needs to move the locking lever 602 to disengage the locking lever 602 from the locking groove 605 on the side of the slide rod 604. Under the traction of the fourth spring 606, the support rod 608 can return to its position.

[0041] Specifically, the movable structure 7 includes a supporting cantilever. A supporting rotating arm 701 is rotatably connected to the side of the frame 1. A roller 702 is rotatably connected to each end of the supporting rotating arm 701. A diagonal brace 703 is rotatably connected to the side of the supporting rotating arm 701. A connecting block 704 is rotatably connected to the other end of the diagonal brace 703. A sliding groove 705 is provided on the frame 1. The connecting block 704 is slidably connected to the frame 1 through the sliding groove 705. An inclined slider 706 is slidably connected to the frame 1. One side of the inclined slider 706 abuts against the connecting block 704. Both ends of the inclined slider 706 are inclined structures. A fifth spring 707 is fixedly connected between the inclined slider 706 and the frame 1. The movable structure 7 provides a more stable movement effect for the entire equipment. When the entire equipment needs to be moved, the user can rotate the support arm 701 on the side of the frame 1 to a horizontal position, so that the roller 702 on the bottom side of the support arm 701 contacts the ground. Through the lever action, the user can complete the rotation of the support arm 701 with less effort. During the rotation of the support arm 701, the diagonal brace 703 will drive the connecting block 704 to slide in the slide groove 705 until the connecting block 704 engages with one end of the inclined slider 706, thereby fixing the horizontal state of the support arm. When the support arms on both sides are extended, the frame 1 becomes more stable during movement due to the increased support area.

[0042] Specifically, the stabilizing structure 8 includes a linkage rod 804. For the two supporting rotating arms 701 located on the same side, the linkage rod 804 is rotatably connected to the side of one of the supporting rotating arms 701. The end of the linkage rod 804 has a locking hole 805. A third positioning block 806 is slidably connected to the inner side of the supporting rotating arm 701. A seventh spring 807 is fixedly connected between the third positioning block 806 and the supporting rotating arm 701. The end of the other supporting rotating arm 701 has a connecting groove 801. A second positioning block 802 is slidably connected to the inner side of the supporting rotating arm 701. The second positioning block 802 is connected to the supporting... A sixth spring 803 is fixedly connected between the rotating arms 701. The device can be moved more easily through the stabilizing structure 8. That is, to further facilitate operation, the two supporting rotating arms 701 located on the same side can be connected by a linkage rod 804 provided on one side, so that they can rotate simultaneously. After rotating the linkage rod 804 on the side of the supporting rotating arm 701, the end of the linkage rod 804 is rotated into the connecting groove 801 at the end of the other supporting rotating arm 701, so that the locking hole 805 at the end of the linkage rod 804 engages with the corresponding second positioning block 802. At this time, the two supporting rotating arms 701 can be rotated simultaneously, which is convenient for operation.

[0043] In use, this invention addresses the issue that, in actual warehousing environments, goods may require storage at varying heights. To facilitate access, a grid structure on the frame 1, consisting of a first horizontal bar 301, a second horizontal bar 303, and a connecting rod 302, can be adjusted in height as needed. Using a positioning latch 304 located inside the frame 1, the fitting strip 307 on the connecting rod 302 on the side of the first horizontal bar 301 can engage with a suitable notch on the side of the positioning latch 304. This determines the positions of the first horizontal bar 301 and the connecting rod 302. After the first horizontal bar 301 is in position, the first positioning block 305 on its inner side abuts against the fixing groove 308 on the frame 1, thus providing support for the first horizontal bar 301. The positioning effect is determined to facilitate the subsequent installation between the second horizontal bar 303 and the plug-in rod 302. Since the height of the first horizontal bar 301 and the second horizontal bar 303 can be changed according to the different fixed positions between the plug-in rod 302 and the positioning clip rod 304, the height of different layers of grid can be adjusted as needed. After determining the position of the first horizontal bar 301, the second horizontal bar 303 is placed at the end of the plug-in rod 302 where the screw 402 is provided. The screw 402 is inserted into the hole at the end of the second horizontal bar 303 so that it abuts against the threaded sleeve 401 in the first limiting groove 405. Through the pushing effect of the abutment washer 403 and the second spring 404, the user only needs to rotate the threaded sleeve 401 to complete the connection between the threaded sleeve 401 and the screw 402. The threaded connection between 02 and the corresponding screw 402 on both sides is completed by threading and fixing the threaded sleeves 401 on both sides to the corresponding screw 402. Since the storage height is usually high, to facilitate the installation of the grid, the positioning rod 304 located inside the frame 1 can be removed or installed from the bottom side of the frame 1. Only an abutment block 508 is provided at the height of the first positioning rod 304 on the bottom side of the frame 1, which facilitates the removal of the positioning rod 304 while also providing a positioning effect for the installed positioning rod 304. After completing the installation of the first positioning rod 304 and the corresponding first crossbar 301 and second crossbar 303, to facilitate the installation of subsequent grids, the user can straighten the installed positioning rod 304 and grid structure. First, lift one positioning rod 304 to its current height, then insert the next positioning rod 304 into the inner side of the frame 1, ensuring that the synchronizing rods 502 in the middle of the two positioning rods 304 are engaged. For the topmost positioning rod 304, its synchronizing rod 502 engages with the end of the positioning rotating block 506 in the middle of the top sliding block 505. After installation, since the distance between the positioning slots 507 on the inner side of the frame 1 is the distance of one positioning rod 304, after all the positioning rods 304 are installed, and ensuring that the end of the synchronizing rod 502 in the last positioning rod 304 engages with the end of the drive rod 504 in the control lever 501, the user can rotate the control lever 501.The synchronizing rod 502 connecting the two ends in the middle allows the positioning rotating block 506 inside the top slider 505 to rotate and engage with the corresponding positioning groove 507. This completes the installation and fixing of all positioning rods 304. Simultaneously, the installation of the grating structure can be completed during the installation of the positioning rods 304 without requiring any lifting. In case of a malfunction of the lifting component 2, to ensure safety during maintenance, support rods 608 are provided on the inner sides of the first horizontal bar 301 and the second horizontal bar 303 on each layer. Users can pull the side supports... The lever 601 causes the slide bar 604 to slide and, through the toothed groove 607, to rotate the toothed ring 609. At this time, the support rod 608 can be rotated out from the side of the first crossbar 301 and the second crossbar 303, providing support and protection for the lifting assembly 2 to be inspected above, preventing the equipment from falling and causing danger or loss. When it is necessary to retract the support rod 608, the user only needs to move the locking lever 602 to disengage the locking lever 602 from the locking groove 605 on the side of the slide bar 604. Under the traction of the fourth spring 606, the support rod 608 can return to its position. When the entire device needs to be moved, the user can rotate the support arm 701 on the side of the frame 1 to a horizontal position, so that the roller 702 on the bottom side of the support arm 701 contacts the ground. Through leverage, the user can rotate the support arm 701 with relatively little effort. During the rotation of the support arm 701, the diagonal brace 703 will drive the connecting block 704 to slide in the slide groove 705 until the connecting block 704 engages with one end of the inclined slider 706, thereby fixing the horizontal state of the support arm. When both support arms on both sides are extended, due to The increased support area makes the frame 1 more stable during movement. To further facilitate operation, the two supporting rotating arms 701 located on the same side can be connected by a linkage rod 804 on one side, allowing simultaneous rotation. After rotating the linkage rod 804 on the side of the supporting rotating arm 701, the end of the linkage rod 804 is rotated into the connecting groove 801 at the end of the other supporting rotating arm 701, so that the locking hole 805 at the end of the linkage rod 804 engages with the corresponding second positioning block 802. At this point, both supporting rotating arms 701 can be rotated simultaneously, facilitating operation.
