Description

Technical Field

[0001] The invention relates to the technical field of hangers, and in particular to a variable angle unit hanger for decoration. Background Art

[0002] Commonly used slings include hooks, wire ropes, chains and other special rigging. Lifting suction cups, clamps and forks can be used as special slings on cranes for a long time, or as replaceable auxiliary slings hung on hooks for temporary use. They are often used in warehouses and yards with multiple cargoes to improve work efficiency. The slings for grabbing bulk materials are generally grabs with jaws that can be opened and closed, and electromagnetic slings can also be used to absorb magnetic materials such as metal chips. The slings for lifting fluid materials are commonly used in barrels and hanging pots. Generally, molten steel or chemical solutions are unloaded by tilting or pulling out the bottom plug, and fluid materials such as concrete are unloaded by opening the bottom door of the hanging pot.

[0030] Reference Figure 1 and Figure 2 A motor 24 is arranged on one side wall of the workbench 1, and the output shaft of the motor 24 extends into the long hole 2421 and is coaxially fixedly connected with the bidirectional screw 245, and a synchronous wheel 1 451 is arranged at the end of the bidirectional screw 245 away from the motor 24, and a synchronous wheel 2441 is installed at the end of the bidirectional screw 144 away from the motor 24, and a synchronous belt 46 is installed on the outside of the synchronous wheel 1 451 and the synchronous wheel 241.

[0031] Reference Figure 1 and Figure 2If the decoration materials to be hoisted are irregular in shape or have a large width, the output shaft of the motor 2 4 is operated to rotate, driving the bidirectional screw 2 45 to rotate, thereby driving the synchronous wheel 1 451 to rotate, and driving the synchronous wheel 1 451 to rotate under the action of the synchronous belt 46, thereby driving the slider 3 432 to move away from the slider 2 431, and driving the slider 1 43 to move away from the slider 2 431; and then adjusting the spacing between the hooks 23 to a width equivalent to that of the decoration materials.

[0032] Reference Figure 1 and Figure 2 If the height of the decoration material is irregular, for example, one end of the decoration material is lower in height and the other end is higher in height, the active roller 1 211 and the active roller 2 212 may be disconnected first.

[0033] Reference Figure 2 and Figure 4 A connecting assembly is provided between the active roller 1 211 and the active roller 2 212, the connecting assembly includes a turntable 1 5 provided on the active roller 1 211, and the connecting assembly also includes a turntable 2 6 provided on the active roller 212, a plurality of fixing holes 32 are provided on the turntable 2 6 at equal intervals, a limit rod 51 is horizontally slidably connected to the turntable 1 5, and when the turntable 1 5 is connected to the turntable 2 6, the limit rod 51 is located inside one of the fixing holes 32; a sliding hole is provided on the turntable 1 5, and the limit rod 51 slides in the sliding hole, and a pull handle 31 is provided at one end of the limit rod 51 away from the fixing hole 32, and an elastic member 52 is sleeved on the outside of the limit rod 51, and one end of the elastic member 52 in the length direction is fixed to the pull handle 31 The other end of the elastic member 52 in the length direction is fixedly connected to the turntable 1 5; first, pull the handle 31 to drive the limit rod 51 to move to the outside of the fixing hole 32, and then rotate the turntable 2 6, thereby driving the active roller 212 to rotate, and then driving the driven roller 215 to rotate, and then adjust the length of the traction rope 22 located outside the active roller 212 and the driven roller 215. After the traction rope 22 is placed to a suitable height, the handle 31 can be released. Under the action of the elastic member 52, the limit rod 51 enters into the inside of the fixing hole 32. At this time, the height difference between the hooks 23 on both sides is relatively large, so that irregular-shaped decoration materials can be hoisted, which is more convenient and more applicable.

[0034] In this embodiment, the elastic member 52 is preferably a spring 32, and may also be other elastic members 52, which can drive the limiting rod 51 to restore.

[0035] The working principle of a variable angle unit hanger for decoration in the embodiment of the present application is as follows: if the decoration material to be hoisted is of irregular shape and the width of the decoration material is large, the output shaft of the control motor 2 4 is rotated to drive the bidirectional screw 2 45 to rotate, and then drive the synchronous wheel 1 451 to rotate, and drive the synchronous wheel 1 451 to rotate under the action of the synchronous belt 46, and then drive the slider 3 432 to move away from the slider 2 431, and drive the slider 1 43 to move away from the slider 2 431; and then adjust the spacing between the hooks 23 to a width equivalent to the decoration material. If the decoration material is irregular in shape, and the width of the decoration material is large, the output shaft of the control motor 2 4 is rotated to drive the bidirectional screw 2 45 to rotate, and then drive the synchronous wheel 1 451 to rotate, and then drive the slider 3 432 to move away from the slider 2 431, and drive the slider 1 43 to move away from the slider 2 431; and then adjust the spacing between the hooks 23 to a width equivalent to the decoration material. If the height is irregular, first pull the handle 31 to drive the limit rod 51 to move to the outside of the fixing hole 32, then rotate the turntable 2 6, and then drive the active roller 212 to rotate, and then drive the driven roller 215 to rotate, and then adjust the length of the traction rope 22 located outside the active roller 212 and the driven roller 215. After the traction rope 22 is placed to a suitable height, release the handle 31, and under the action of the elastic member 52, the limit rod 51 enters into the fixing hole 32. At this time, the height difference between the hooks 23 on both sides is relatively large, so irregular shaped decoration materials can be hoisted, which is more convenient and more applicable.

[0036] The application also provides a hoisting method.

[0037] A hoisting method comprises the following steps: S1: If the width of the decoration material is large, the slider 1 43 is moved away from the slider 2 431, and the slider 3 432 is moved away from the slider 4 433, so that the distance between the hooks 23 is adjusted to a width corresponding to the decoration material; if the width of the decoration material is small, the slider 1 43 is moved toward the slider 2 431, and the slider 3 432 is moved toward the slider 4 433, so that the distance between the hooks 23 is adjusted to a width corresponding to the decoration material; S2: If the height of the decoration material is irregular, pull the handle 31, the limit rod 51 moves to the outside of the fixing hole 32, rotate the turntable 2 6, drive the active roller 212 to rotate, and drive the driven roller 215 to rotate to adjust the length of the traction rope 22 located outside the active roller 212 and the driven roller 215. After the traction rope 22 is placed to a suitable height, release the handle 31. Under the action of the elastic member 52, the limit rod 51 enters into the inside of the fixing hole 32. At this time, the height difference between the hooks 23 on both sides is relatively large, and irregularly shaped decoration materials can be hoisted.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.

A hoisting method, characterized in that: Using the variable angle unit hanger for decoration and decoration as claimed in claim 8 to hang irregular decoration materials comprises the following steps: S1: If the width of the decoration material is large, the slider 1 (43) is manipulated to move in a direction away from the slider 2 (431), and the slider 3 (432) is manipulated to move in a direction away from the slider 4 (433), so that the spacing between the hooks (23) is adjusted to a width corresponding to the decoration material; if the width of the decoration material is small, the slider 1 (43) is manipulated to move in a direction close to the slider 2 (431), and the slider 3 (432) is manipulated to move in a direction close to the slider 4 (433), so that the spacing between the hooks (23) is adjusted to a width corresponding to the decoration material; S2: If the height of the decoration material is irregular, the pull handle (31) is pulled, the limit rod (51) is moved to the outside of the fixing hole (32), and the turntable (6) is rotated to drive the active roller (212) to rotate, and drive the driven roller (215) to rotate to adjust the length of the traction rope (22) located outside the active roller (212) and the driven roller (215). After the traction rope (22) is placed to a suitable height, the pull handle (31) is released, and under the action of the elastic member (52), the limit rod (51) enters into the inside of the fixing hole (32). At this time, the height difference between the hooks (23) on both sides is relatively large, so that the decoration materials of irregular shapes can be hoisted.
