[0031] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the sake of description, only the parts related to the present utility model are shown in the drawings, rather than all the structures.

[0035] For the hoisting of wall panels, the traditional solution usually uses a crane and a hoisting tool installed on the crane to lift the wall panels, and the hoisting tool can only move in the vertical direction, with poor flexibility. In this regard, the prior art provides a metal wall panel hoisting device, which is provided with an I-shaped track beam and a sliding connecting rod. The hoisting assembly is installed on the sliding connecting rod and is used to lift the metal wall panel, and the sliding connecting rod can slide relative to the I-shaped track beam, so as to drive the metal wall panel to move along the extension direction of the I-shaped track beam to adjust the position of the metal wall panel. However, the problem is that the metal wall panel hoisting device can only adjust the position of the metal wall panel along the extension direction of the I-shaped track beam, and the flexibility is still poor.

[0036] Referring to Figures 1 - 3 , the hoisting tool is used to lift the item to be hoisted. Among them, the item to be hoisted can be a plate-shaped item or a strip-shaped item. In this embodiment, the item to be hoisted is a wall panel. In addition, the item to be hoisted has two hoisting parts.

[0037] Continuing to refer to Figures 1 - 3 , the hoisting tool includes a mounting bracket 1 and a hoisting assembly. The mounting bracket 1 includes two sliding rods 11 arranged in parallel and at intervals. Both sliding rods 11 extend in a direction parallel to the horizontal plane. Among them, the horizontal heights of the two sliding rods 11 are the same. The hoisting assembly includes two sliding bases 2 and hoisting members 3. There are two sliding bases 2, and the two sliding bases 2 are slidably arranged on the two sliding rods 11 in a one-to-one correspondence; there are two hoisting members 3, and the two hoisting members 3 are connected to the two sliding bases 2 in a one-to-one correspondence, and the hoisting members 3 are rotatably arranged on the sliding bases 2. The two hoisting members 3 can cooperate with the two hoisting parts respectively to lift the item to be hoisted. Among them, the rotation center line of the hoisting member 3 relative to the sliding base 2 is parallel to the vertical direction. By rotating the hoisting member 3 relative to the sliding base 2, the angle of the item to be hoisted can be finely adjusted. In addition, by sliding the sliding base 2 relative to the sliding rod 11, the item to be hoisted can be driven to move along the axis direction of the sliding rod 11 to adjust the position of the item to be hoisted. This hoisting tool can simultaneously complete the adjustment of the horizontal position and the angle of the item to be hoisted, with strong flexibility and can be applied to different installation scenarios.

[0038] Continuing to refer to Figures 1 - 3, the sliding base 2 includes a slider 21 and a rotating shaft 22. The slider 21 is slidably arranged on the sliding rod 11; the rotating shaft 22 is arranged on one of the slider 21 and the hoisting member 3 and is rotatably connected to the other. In this embodiment, an exemplary solution is given where the rotating shaft 22 is connected to the slider 21 and the hoisting member 3 is rotatably engaged with the rotating shaft 22. In this embodiment, the rotating shaft 22 is a long bolt threadedly connected to the slider 21. The long bolt rotatably passes through the hoisting member 3, and the head of the long bolt abuts against the hoisting member 3 in the vertical direction to prevent the hoisting member 3 from falling off. Optionally, in order to prevent the long bolt from loosening relative to the slider 21, a locking nut can also be provided. The locking nut is threadedly connected to the long bolt and abuts against the slider 21.

[0039] Continue to refer to Figures 1 - 3 , the sliding base 2 is rotatably connected with rollers 211. In this embodiment, the rollers 211 are specifically installed on the slider 21. The rollers 211 are in rolling contact with the sliding rod 11, thereby reducing the friction when the slider 21 slides relative to the sliding rod 11. Among them, the rollers 211 and the connecting shafts of the rollers 211 (i.e., the rotation centers of the rollers 211) are both located above the sliding rod 11. Optionally, the slider 21 is a U-shaped plate, and the connecting shafts of the rollers 211 are respectively connected to both ends of the U-shaped plate.

[0040] Optionally, when adjusting the angle of the item to be lifted, the item to be lifted will have a certain angular offset. At the same time, the distance between the connection point of one sliding base 2 and one sliding rod 11 and the connection point of the other sliding base 2 and the other sliding rod 11 will also increase, while the distance between the two hoisting parts of the item to be lifted remains unchanged. That is to say, the distance between the connection point of one hoisting member 3 and the item to be lifted and the connection point of the other hoisting member 3 and the item to be lifted remains unchanged, which will cause a certain angular offset of the sliding base 2 relative to the sliding rod 11. In this regard, in this embodiment, the two sliding bases 2 can also rotate slightly relative to the sliding rod 11.

[0041] Continue to refer to Figures 1 - 3 , the hoisting part is a hoisting hole opened on the item to be lifted. The hoisting member 3 includes a support member 31 and a hoisting pin shaft 32 arranged on the support member 31. The support member 31 is U-shaped and has a first support plate 311, a connecting plate 312, and a second support plate 313 connected in sequence. The connecting plate 312 is connected to the sliding base 2. The first support plate 311 and the second support plate 313 are parallel and spaced apart. The item to be lifted can extend between the first support plate 311 and the second support plate 313. The hoisting pin shaft 32 can pass through the first support plate 311, the hoisting hole, and the second support plate 313 in sequence, so that the hoisting member 3 can lift the item to be lifted by passing the hoisting pin shaft 32 through the hoisting hole. As an alternative solution, the hoisting member 3 can also be a hook and can directly lift the item to be lifted. In addition, the hoisting member 3 can also be other types of hoisting structures.

[0042] Continue to refer to Figures 1 - 3 , a first receiving groove 3111 is formed in the first support plate 311, a second receiving groove 3131 is formed in the second support plate 313, the lifting pin shaft 32 is disposed in both the first receiving groove 3111 and the second receiving groove 3131, and first stoppers 321 and second stoppers 322 are respectively disposed at both ends of the lifting pin shaft 32. The first stopper 321 can abut against the first support plate 311 along the axial direction of the lifting pin shaft 32, and the second stopper 322 can abut against the second support plate 313 along the axial direction of the lifting pin shaft 32, thereby limiting the movement of the lifting pin shaft 32. Specifically, both the first support plate 311 and the second support plate 313 are located between the first stopper 321 and the second stopper 322, so as to prevent the lifting pin shaft 3 from falling off; alternatively, both the first stopper 321 and the second stopper 322 are located between the first support plate 311 and the second support plate 313, which can also prevent the lifting pin shaft 3 from falling off.

[0043] Optionally, the first receiving groove 3111 is L-shaped and has a horizontal section and a vertical section, and the opening is located in the horizontal section. The lifting pin shaft 32 can pass through the horizontal section and is finally installed in the vertical section. During the lifting operation, the lifting pin shaft 32 is located in the vertical section. Such a setting can prevent the lifting pin shaft 32 from slipping out of the first receiving groove 3111 along the opening of the first receiving groove 3111. In addition, the second receiving groove 3131 also adopts a similar structure and will not be described in detail.

[0044] Continue to refer to Figures 1 - 3 , a plurality of lifting assemblies are provided, and the plurality of lifting assemblies are sequentially arranged along the axial direction of the sliding rod 11, so that the lifting device can lift a plurality of items to be lifted at the same time, which can improve the lifting efficiency, and the sliding base 2 of each lifting assembly can slide relative to the sliding rod 11, and the lifting member 3 can rotate relative to the sliding base 2, so as to adjust the horizontal position and angle of each item to be lifted.

[0045] When the lifting device lifts a plurality of items to be lifted at the same time, during the process of adjusting the horizontal position and angle of the items to be lifted, collisions may occur between adjacent two lifting assemblies. In this embodiment, lifting assembly buffer blocks 41 are disposed on both sides of any lifting assembly along the axial direction of the sliding rod 11, so as to buffer through the lifting assembly buffer blocks 41 and avoid damage caused by collisions between the lifting assemblies. Among them, each lifting assembly is provided with two lifting assembly buffer blocks 41, and the two lifting assembly buffer blocks 41 are respectively disposed on the first support plate 311 and the second support plate 313.

[0046] Continue to refer to Figures 1 - 3, limiting plates 12 are provided at both ends of the two sliding rods 11. The limiting plates 12 can abut against the sliding base 2 along the axial direction of the sliding rods 11, so as to limit the sliding of the sliding base 2, prevent the sliding base 2 from moving excessively, and prevent the sliding base 2 from disengaging from the sliding rods 11.

[0047] Continue to refer to Figures 1 - 3 , the mounting bracket 1 further includes a connecting structure 13 that connects the two sliding rods 11 at the same time. A connecting structure buffer block 42 is provided on the side of the connecting structure 13 close to the hoisting assembly, so as to provide buffering and prevent the sliding base 2 of the hoisting assembly from directly hitting the connecting structure 13 when the hoisting assembly is moving.

[0048] Optionally, the connecting structure 13 includes a connecting rod 131, a connecting steel pipe 132, a protective support frame 133 and two connecting bottom plates 134. The two sliding rods 11 are fixedly connected to the two connecting bottom plates 134 in a one-to-one correspondence. The connecting rod 131, the connecting steel pipe 132 and the protective support frame 133 are all fixedly connected to the two connecting bottom plates 134 at the same time to fix the two sliding rods 11. Among them, the connecting rod 131 and the connecting steel pipe 132 are both arranged between the two sliding rods 11. Among them, the connecting rod 131 is further provided with a limiting bracket 1311. The limiting bracket 1311 has a mounting hole for connecting the boom. The connecting structure 13 is connected to the boom of the forklift truck through the connecting steel pipe and the limiting bracket 1311, so as to connect the lifting device to the boom of the forklift truck. The protective support frame 133 is rectangular, and along the horizontal direction, the distance between the two side frames of the protective support frame 133 is greater than the distance between the two connecting bottom plates 134. That is to say, the overall width of the protective support frame 133 is relatively wide. While improving the overall structural strength, it can also limit the hoisting assembly and the item to be hoisted to prevent the hoisting assembly and the item to be hoisted from colliding with the boom. Optionally, the connecting structure buffer block 42 is arranged on the protective support frame 133. In this embodiment, four connecting structure buffer blocks 42 are arranged, and the four connecting structure buffer blocks 42 are respectively arranged on the four side frames of the protective support frame 133.

[0049] This embodiment also provides a forklift truck, which includes the above-mentioned lifting device, and also includes a vehicle body and a boom arranged on the vehicle body. The mounting bracket 1 is mounted on the boom. The lifting device can simultaneously adjust the horizontal position and angle of the item to be hoisted, with strong flexibility, and can be applied to different installation scenarios. Moreover, the forklift truck can transport the lifting device to complete the short-distance transportation of the item to be hoisted.

[0050] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
