[0035] A telescopic cylinder 6 is arranged in parallel on the lifting rod 2, and the telescopic cylinder 6 is configured to control the extension section 3 to extend or retract. Figure 2 As shown, the telescopic cylinder 6 is fixed with the tilting frame 1 as a carrier, and the telescopic section of the telescopic cylinder 6 is connected to the extension section 3 through the connecting block 7. When the telescopic cylinder 6 is telescoped, the extension section 3 is synchronously driven to telescope through the connecting block 7.

[0036] In this embodiment, the tilting frame 1 is rotatably connected to the base, and the tilting frame 1 is rotated around the rotating connection to adjust the direction of the tilting frame 1, wherein a locking member 8 is provided at the rotating connection, and the locking member 8 is used to fix the state of the tilting frame 1. The locking member 8 is, for example, a locking screw structure, and a plurality of screw holes are circumferentially arranged on the base, and a locking screw is arranged on the tilting frame 1. When it is rotated to a suitable position, the locking operation can be achieved by inserting the locking screw into the corresponding screw hole.

[0037] refer to Figure 1 As shown, the lifting frame also includes a transport frame 9 and a pallet 10 arranged in parallel with the lifting rod 2, and the transport frame 9 and the pallet 10 are used to transport building materials from a lower position to a higher position, and can stay at the higher position for use by users, and to transport objects from a higher position to a lower position;

[0038] refer to Figure 1 and Figure 3 As shown, the transport frame 9 includes a first frame body 901 located at the base and parallel to the bottom surface, a second frame body 902 located at the pulley block 4, and an intermediate frame body 903 connecting the first frame body 901 and the second frame body 902.

[0039] Among them, reference Figure 2 As shown, the first frame 901 includes a pair of parallel rods and a plurality of connecting rods connecting the two parallel rods. The connecting rods can be a telescopic structure or a connecting rod of a fixed length. The bottoms of the two parallel rods are connected to the horizontal section 102 of the inclined frame 1 through support rods to support the first frame 901. The two parallel rods are arc-shaped near the center frame so that they can be smoothly connected to the middle frame 903.

The arc rod 11 passes through the pull rod 12 of the U-shaped frame structure, one end of which is hinged to the parallel rods of the middle frame 903, and the other end is hinged to the parallel rods of the second frame 902. This structural setting can enable the second frame 902 to swing upward around the middle frame 903 through the arc rod 11 as needed, thereby exposing the space above the pulley block 4 to avoid the second frame 902 from blocking the space above the pulley block 4. The second frame 902 can also be swung as needed to make it parallel to the ground. In this state, the arc rod 11 cooperates with the pull rod 12, so that the second frame 902 cannot continue to swing downward, so that it remains in a horizontal state. In this state, the ends of the parallel rods of the second frame 902 overlap and splice with the corresponding ends of the parallel rods of the middle frame 903.

[0042] refer to Figure 3 As shown, in this embodiment, the slide groove 13 and the slider are combined to realize the sliding of the tray 10 along the transport frame 9, wherein the slide groove 13 is provided on each parallel rod; Figure 4-Figure 5 As shown, a slide bar is provided at the bottom of the pallet 10, and the number of the slide bars is two, corresponding to the two parallel bars respectively. The slide bar includes a half-tube structure 14 wrapped around the outside of the parallel bars, and a slider structure 15 inserted into the slide groove 13. The half-tube structure 14 is wrapped around the outside of the parallel bars, and the slider is inserted into the slide groove 13 to improve the stability of the pallet 10 sliding along the transport frame 9; wherein the power structure for controlling the sliding of the pallet 10 adopts a pull rope 16 and a traction motor 18, that is, a pull rope 16 is arranged between the first frame 901 and the second frame 902 along the middle frame 903, and the pull rope 16 is connected to the traction motor 18 and the pallet 10, and a pulley structure can be arranged at the first frame 901 and the second frame 902 to facilitate the arrangement of the pull rope 16, and the traction motor 18 controls the pull rope 16 to pull the pallet 10 upward so that it can move from the first frame 901 to the second frame 902, or controls the pull rope 16 to pull the pallet 10 downward so that it slides from the second frame 902 to the first frame 901;

[0043] Among them, reference Figure 4 As shown, there are a plurality of holes 19 densely distributed in the center of the pallet 10. When construction materials are placed on the pallet 10, the materials can be bound and fixed by passing binding parts through the corresponding holes 19, and various baffles can also be assembled in the holes 19 to form enclosures, so that the materials can be stably and safely placed on the pallet 10 for transportation operations.

[0044] refer to Figure 6As shown, the base includes a bottom frame 20 and a column 21 located at the center of the bottom frame 20, the tilting frame 1 is connected to the top of the column 21, and moving wheels 22 are installed at the four corners of the bottom frame 20. The center of each side of the bottom frame 20 is provided with a first hydraulic support rod 23 in the vertical direction. The bottom frame 20 is supported by the moving wheels 22 or by the first hydraulic support rod 23 in an extended state.

[0045] When the hoisting operation is not performed, the first hydraulic support rod 23 is in a retracted state, at which time the moving wheel 22 is in contact with the ground, and the hydraulic support rod is separated from the ground, and the moving wheel 22 can be used to move the device so as to adjust the position of the device indoors;

[0046] When the hoisting operation is performed, the first hydraulic support rod 23 is extended, contacts the ground, and props up the entire bottom frame 20. At this time, the moving wheels 22 are separated from the ground. In this state, the bottom frame 20 is in a state of being supported by multiple first hydraulic support rods 23, thereby improving the stability of the hoisting.

[0047] In this embodiment, reference Figure 7-Figure 8 As shown, a pair of channels 24 are provided in parallel on both sides of the bottom frame 20, and a cross bar 25 is passed through the two channels 24, wherein a second hydraulic support rod 26 is installed at the protruding end of each cross bar 25, and the second hydraulic support rod 26 and / or the first hydraulic support rod 23 support the bottom frame 20, and a long groove 27 is provided in the cross bar 25, and a roller 28 is provided in the channel 24 and at the groove, and the roller 28 is inserted into the long groove 27. When the first hydraulic support rod 23 and the second hydraulic support rod 26 alternately support the bottom frame 20, the roller 28 rolls along the long groove 27, so that relative sliding occurs between the bottom frame 20 and the cross bar 25.

[0048] On the one hand, when the first hydraulic support rod 23 and the second hydraulic support rod 26 are supporting at the same time, the stability of the device can be further improved by increasing the bottom area;

[0049] On the other hand, the moving operation can be realized in a stable state, that is, in the hoisting state, it is first supported by the second hydraulic support rod 26. At this time, the first hydraulic support rod 23 and the moving wheel 22 are both detached from the ground, and the roller 28 rolls in the long groove 27, so that the bottom frame 20 can be easily moved along the cross bar 25. Among them, the roller 28 can be set into a gear structure by arranging a rack in the long groove 27, and the gear is driven to rotate by a driving motor to realize the moving operation; when the bottom frame 20 moves to a certain distance, the first hydraulic support rod 23 extends and contacts the ground, and the second hydraulic support rod 26 retracts. At this time, the cross bar 25 can be moved. After the cross bar 25 moves, the above operation is repeated, and the continuous movement operation of the device can be realized in one direction.
