Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bagged powder hoisting, in particular to a bagged powder hoisting device. BACKGROUND

[0002] Many powders such as mullite sand powder are stored by using packaging bags. This storage method has the advantages of large storage volume, convenient transportation and low use cost, and thus is widely applied. The packaging bags need to be hoisted by a travelling crane when receiving materials at a discharge port and when subsequent loading into a vehicle. A lifting tool is arranged at a hook of the travelling crane. Four lifting straps of the packaging bag are hung on the lifting tool to realize hoisting and transfer of the bagged powder. Since the packaging bag containing the powder has a large volume and an irregular shape, the packaging bag is prone to deviating from the lifting tool during hoisting, which may cause certain safety hazards during hoisting and transfer. SUMMARY

[0003] The utility model aims at providing a bagged powder hoisting device which can solve the technical problem of safety hazards caused by the relative movement of the bagged powder from the lifting tool during hoisting. The extrusion of the lifting strap of the packaging bag on the pressing plate during hoisting causes the limiting rod to extend, thereby effectively limiting the relative position of the packaging bag, reducing the deviation of the packaging bag during hoisting and improving the safety of hoisting.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0005] A bagged powder hoisting device comprises a hanger. A hanger hole is arranged at the top of the hanger. Multiple hanging rods are arranged in an array on the side surface of the hanger. An opening is arranged at the top of the hanging rod. A pressing plate is connected to the opening in a vertical sliding manner. A compression spring is arranged between the pressing plate and the hanging rod. Multiple limiting rods are arranged at the opening. When the pressing plate slides downward, the limiting rods extend to the outside of the opening in a horizontal or vertical manner.

[0006] Further, the inside of the hanging rod is provided with a cavity. The opening is arranged on the side wall of the cavity. The longitudinal section of the pressing plate is arc-shaped.

[0007] Further, the limiting rod comprises a horizontal rod and a vertical rod. The vertical rod is fixed in the cavity. Multiple vertical perforations are arranged on the pressing plate. The vertical rod passes through the perforations and is connected to the perforations in a sliding manner. Multiple horizontal sliding holes are arranged on the side wall of the cavity. The horizontal rod passes through the sliding holes and is connected to the sliding holes in a sliding manner. A steering assembly is arranged on the pressing plate to drive the horizontal rod to slide.

[0008] Furthermore, the cavity is provided with multiple fixed posts, the bottom of the pressure plate is provided with multiple sliding sleeves, the sliding sleeves are slidably sleeved on the outside of the fixed posts, the compression spring is disposed between the top of the fixed posts and the top of the sliding sleeves, and the steering assembly is disposed between the sliding sleeves and the transverse rod.

[0009] Furthermore, the steering assembly includes a link, the top of which is rotatably connected to the side of the slide sleeve, and the bottom of which is rotatably connected to the lateral rod.

[0010] Furthermore, the ends of both the horizontal and vertical bars are arc-shaped.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model has a lifting hole at the top of the hanger to facilitate the cooperation with the hook of the overhead crane. At the same time, multiple hanging rods are arranged in an array on the side of the hanger. The top of the hanging rod has a notch, and a pressure plate is slidably connected to the notch along the vertical direction. A compression spring is provided between the pressure plate and the hanging rod. Under the action of the compression spring, the pressure plate floats above the notch and closes the notch, so that the surface of the hanging rod remains flat. This makes it more convenient to hang or remove the packaging bag from the hanging rod, thus improving the convenience of the lifting operation.

[0013] 2. Multiple limiting rods are installed at the notch. When the packaging bag is lifted, the lifting straps squeeze the pressure plate, causing the pressure plate to slide downward relative to the hanging rod. As the pressure plate slides downward, the limiting rods extend laterally or vertically to the outside of the notch. This structure ensures that when the hanging rod lifts the packaging bag, multiple limiting rods extend laterally or vertically, forming limiting blocks on both sides of the lifting straps. This prevents the lifting straps from shifting too far on the hanging rods, effectively limiting the overall position of the packaging bag and greatly improving the safety of lifting. After the packaging bag is placed in place, the pressure plate loses its compression and resets under the action of the compression spring, causing the pressure plate to slide upward relative to the hanging rods to cover the notch. This keeps the surface of the hanging rods flat, facilitating the quick separation of the lifting device from the lifting straps without the need for manual intervention in the state of the limiting rods, further improving the convenience of using the lifting device.
