[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a steel structure plate hoisting device, including a mobile base 1, four sets of wheels 15 at the bottom of the mobile base 1, a hoisting frame 3 with a folding structure 2 on one side of the upper end of the mobile base 1, a height adjustment plate 4 on the hoisting frame 3, and the hoisting height is adjusted by the height adjustment structure 5.

[0027] A handle frame 6 is provided on the other side of the mobile base 1. A push-pull handle 16 is provided on one side of the handle frame 6. A winding drum 7 is rotatably installed on the upper end of the handle frame 6. A steel wire rope 8 is wound on the winding drum 7. A pulley frame 9 is provided on one side of the upper end of the height adjustment plate 4. A pulley block 10 is rotatably installed on the pulley frame 9. The steel wire rope 8 is hoisted upward through the pulley block 10. A strip-shaped opening 14 is provided near the upper end of the height adjustment plate 4. The steel wire rope 8 on the winding drum 7 passes through the strip-shaped opening 14 and connects to the pulley block 10.

[0028] A turntable 11 is coaxially mounted on one side of the winding drum 7. An eccentric rod 12 is mounted on the outside of the turntable 11. A crank handle 13 is sleeved on the outside of the eccentric rod 12. The crank handle 13 is rotatably connected to the eccentric rod 12.

[0029] The basic load-bearing part of the device is the mobile base 1, which is welded from high-strength Q235 square tubes. A set of wheels 15 are installed at the four corners of the bottom. The wheels 15 are made of wear-resistant rubber and are equipped with a two-way braking function, which not only ensures the flexible movement of the device on flat ground, but also ensures stable fixation during hoisting operations, effectively preventing safety accidents caused by slippage. The hoisting frame 3 is connected to the mobile base 1 through the folding structure 2. The hoisting frame 3 is made of rectangular steel tubes. The height adjustment plate 4 can move up and down along the vertical direction of the hoisting frame 3 to achieve precise adjustment of the hoisting height. Its movement and fixation are accomplished by the height adjustment structure 5. The push-pull handle 16 makes it convenient for operators to push the device to move and control the stability during hoisting. The push-pull handle 16 is made of round steel tubes and the surface is covered with anti-slip rubber sleeves to increase the friction between the operator's hands and the handle, improving the comfort and safety of operation.

[0030] In the hoisting transmission and operation components, to change the direction of force on the wire rope 8 and achieve upward hoisting of the steel structure plates, a pulley frame 9 is welded to one side of the upper end of the height adjustment plate 4. A pulley block 10 is rotatably mounted on the pulley frame 9 via a pin. The pulley block 10 consists of two movable pulleys and one fixed pulley (the pulley block 10 in the attached drawing has been simplified for ease of review). Since the height adjustment plate 4 needs to move up and down, to ensure that the wire rope 8 can pass smoothly through and connect to the pulley block 10, an opening is made near the upper end of the height adjustment plate 4. A strip-shaped opening 14 is provided, with chamfered edges to prevent scratching of the wire rope 8 during its movement. One end of the wire rope 8 is wound around the drum 7, and the other end passes through the strip-shaped opening 14, then passes around each pulley of the pulley block 10 in sequence, and finally connects to the hook used for hoisting the steel structure plate. The operator can rotate the drum 7 by holding the crank handle 13 and rotating it around the axis of the turntable 11, thereby realizing the winding and unwinding of the wire rope 8, and thus completing the hoisting or lowering operation of the steel structure plate.

[0031] The folding structure 2 includes two support rods 21. One end of the support rod 21 is rotatably mounted on the movable base 1, and the other end of the support rod 21 is provided with a latch 22. Each side of the hoisting frame 3 is provided with a locking post 23. One end of the locking post 23 is connected by a nut 24 for fixing the support rod 21 through a thread. When the latch 22 is engaged with the locking post 23, the hoisting frame 3 is supported.

[0032] The folding structure 2 is used to fold and unfold the lifting frame 3. One end of each support rod 21 is rotatably connected to the movable base 1 via a pin, and the other end can separate or engage the lifting frame 3. The latch 22 is U-shaped, and the locking post 23 is a cylindrical structure. To fix the support rod 21 after the lifting frame 3 is unfolded and prevent it from loosening, an external thread is machined on one end of the locking post 23, and a nut 24 is provided. When the lifting frame 3 needs to be unfolded, the operator first lifts the lifting frame 3 upward, then rotates the support rod 21 to engage the latch 22 of the support rod 21 with the locking post 23, and then tightens the nut 24 to firmly fix the support rod 21 on the locking post 23. At this time, the lifting frame 3 is stably supported and can be used for lifting operations. When the device needs to be stored, simply loosen the nut 24 and detach the support rod 21 from the locking post 23, and the lifting frame 3 can be folded downward to the upper end of the movable base 1, reducing the overall volume of the device and facilitating transportation and storage.

[0033] The height adjustment structure 5 includes a slider 51 located at the bottom of the height adjustment plate 4. The slider 51 is slidably connected to the hoisting frame 3. A lifting handle 52 for driving the height adjustment plate 4 to rise and fall is provided on one side of the slider 51. An adjustment rod 53 is threadedly connected to the bottom of the height adjustment plate 4. An adjustment knob 54 is provided at one end of the adjustment rod 53. A plurality of adjustment holes 55 are provided near the upper end of the hoisting frame 3. When the adjustment rod 53 is inserted into the adjustment hole 55, the height adjustment plate 4 is fixed.

[0034] The height adjustment structure 5 is used to raise, lower, and fix the height adjustment plate 4. The slider 51 is installed at the bottom of the height adjustment plate 4 and is a rectangular block structure. The slider 51 has a groove inside that matches the hoisting frame 3. The operator can easily push the slider 51 and the height adjustment plate 4 up and down along the hoisting frame 3 by holding the lifting handle 52 to adjust to a suitable hoisting height. Multiple adjustment holes 55 can meet the hoisting requirements of different heights. After the operator adjusts the height adjustment plate 4 to the required height, he only needs to turn the adjustment knob 54 to move the adjustment rod 53 towards the hoisting frame 3, so that one end of the adjustment rod 53 is inserted into the corresponding adjustment hole 55, which can firmly fix the height adjustment plate 4 on the hoisting frame 3 and ensure the stability of the hoisting operation. If the height needs to be adjusted again, turn the adjustment knob 54 in the opposite direction to pull the adjustment rod 53 out of the adjustment hole 55, and then push the lifting handle 52 to adjust the position of the height adjustment plate 4.

[0035] Working principle and usage process of this utility model:

[0036] (I) Device Deployment

[0037] Lifting frame 3 unfolds and is fixed: Lift the lifting frame 3 upwards, rotate the support rods 21 on both sides so that the latches 22 at the end of the support rods 21 engage with the locking posts 23 on both sides of the lifting frame 3, and tighten the nuts 24 at the end of the locking posts 23 with a tool to ensure that the support rods 21 are firmly fixed to the lifting frame 3 and the lifting frame 3 is stably supported.

[0038] Pre-adjustment of height adjustment plate 4: According to the height of the plate to be hoisted and the target hoisting position, hold the lifting handle 52 at the bottom of the height adjustment plate 4, push the slider 51 to slide vertically along the hoisting frame 3, adjust the height adjustment plate 4 to a suitable height, turn the adjustment knob 54 to insert the adjustment rod 53 into the corresponding adjustment hole 55, and fix the height adjustment plate 4.

[0039] (II) Sheet hoisting

[0040] Hook connection of the plate: Connect one end of the wire rope 8 wound on the drum 7 (passing through the strip opening 14 and around the pulley block 10) to the hook and hang it on the special lifting point of the steel structure plate to be lifted (ensure that the lifting points are symmetrical and avoid the plate from tilting). Check whether the hook connection is firm and confirm that the center of gravity of the plate is stable.

[0041] Lifting of sheet metal: The operator stands on one side of the handle frame 6, holds the crank handle 13, and slowly rotates it clockwise (along the axis of the turntable 11).
