Technical Field

[0001] The utility model belongs to the technical field of building construction equipment, and in particular relates to a building material hoist. Background Art

[0002] During the construction of high-rise buildings, materials need to be transported to higher floors. Currently, hoists are typically used to lift materials onto the structure. To use the hoist, it must be set up on the floor where the materials are needed. However, when setting up the hoist on-site, the hoist arm must be extended to the exterior of the building to lift the materials. However, the hoist arm on most hoists currently has a fixed tilt angle and height. Due to the layout of the on-site buildings, the hoist arm can easily interfere with the roof during indoor assembly. Therefore, the arm must be extended to the exterior of the building before assembly. This makes hoist operation inconvenient during on-site installation. Utility Model Content

An adjustment rod 5 is hingedly mounted on both sides of the support arm 41 along the first direction. Connecting sleeves 51 corresponding to the connecting rods are rotatably mounted on both sides of the fixing frame 3. The two adjustment rods 5 are slidably mounted within the connecting sleeves 51. Two stoppers 52 are threadedly mounted on each adjustment rod 5. The provision of two adjustment rods 5 enhances the support strength of the support arm 41, ensuring the safety of the hoist during use.

[0030] In some embodiments, the connecting sleeve 51 may be Figure 2 See the structure shown. Figure 2 A rotating rod 511 is rotatably mounted on the fixed frame 3.

Connecting sleeves 51 are fixedly mounted on both sides of the rotating rod 511, and the axes of the connecting sleeves 51 at both ends of the rotating rod 511 are arranged parallel to each other. This facilitates adjustment of the relative positions of the two adjustment rods 5.

[0031] Specifically, in this embodiment, the connecting sleeve 51 and the rotating rod 511 are integrally formed, and the axis of the connecting sleeve 51 and the axis of the rotating rod 511 are perpendicular to each other. The rotating rod 511 is rotatably mounted on the fixing frame 3 around its axis.

[0032] In some embodiments, the support arm 41 may be configured as follows: Figure 1 、 Figure 2 See also Figure 1 、 Figure 2 The end of the support arm 41 away from the hoisting arm 4 and the top of the fixed frame 3 are both rotatably provided with a guide pulley 31 for guiding the wire rope of the hoist 6. The guide pulleys 31 are rotatably provided at the ends of the support arm 41 and the fixed frame 3. The axes of the two guide pulleys 31 are both arranged along the first direction. The wire rope on the hoist 6 is sequentially overlapped on the guide pulley 42 on the support arm 41 from the hoist 6, and then transported to the guide pulley 31 on the fixed frame 3, and finally transported to the guide pulley 42 at the end of the hoisting arm 4. It extends downward under the guidance of the guide pulley 42 to hoist the material. It can effectively guide the wire rope on the hoist 6. At the same time, the guide pulleys 31 installed on the support arm 41 and the fixed frame 3 can improve the support effect of the wire rope during the material hoisting process.

During transportation, the extension rod 8 and the extension rod 9 can be stored on the placement rack 1 to reduce the space occupied by the placement rack 1.

[0040] Specifically, in this embodiment, the weight object is a sandbag or a large waste concrete block.

[0041] In some embodiments, the extension rod 9 may be Figure 1 、 Figure 3 See also Figure 1 、 Figure 3 The opposite ends of the two extension rods 9 are detachably connected, and a limiting plate 91 for clamping between the two extension rods 9 is installed in the middle of the placement rack 1. A connecting portion is fixedly installed at the opposite ends of the two extension rods 9. The connecting portion is arranged along the radial direction of the extension rods 9, and the connecting portions on the two extension rods 9 are correspondingly provided with through holes, and the two connecting portions can be connected together by bolts and nuts. A limiting portion is also fixedly installed on the placement rack 1. When the two extension rods 9 are accommodated in the placement rack 1 and connected together, the ends of the extension rods 9 rest against the limiting plate 91, so that the two extension rods 9 can be fixed to the placement rack 1 through the limiting plate 91, bolts and nuts.
