[0018] The portable hoisting device for indoor decoration provided in this embodiment, compared with the prior art, is equipped with a hoisting frame 1, which is fixedly installed on the indoor ground. A hoisting arm 11 is fixedly installed on the hoisting frame 1, extending outdoors. A trolley 2 is installed on the hoisting arm 11, which can move along the length of the hoisting arm 11 to transport materials indoors and outdoors. A hook for hoisting items is also installed on the trolley 2, which can move vertically on the trolley 2 to achieve vertical lifting of materials. In this application, support rods 3 are installed on both sides of the hoisting frame 1, and the support rods 3 are fixed by being pressed against the ground and roof. A connecting frame 4 is fixedly installed between the two support rods 3, located above the hoisting arm 11. The position of the connecting frame 4 on the support rod 3 can be adjusted vertically to match the connection between the hook frame 5 and the hoisting arm 11. During on-site construction, the hoisting frame 1 can be fixed to the indoor ground first. Then, according to the position of the hoisting arm 11, two support rods 3 are fixed on both sides of the hoisting arm 11. Finally, the connecting frame 4 is installed on the two support rods 3. By adjusting the position of the connecting frame 4 on the support rods 3, the hook frame 5 is connected to the hoisting arm 11. Finally, after adjusting the tension between the hook frame 5 and the hoisting arm 11, the connecting frame 4 is fixed to the support rods 3, thereby reinforcing the hoisting arm 11 and facilitating the alignment and adjustment of the support position. The operation process is simple and convenient.

[0019] In some embodiments, the hook bracket 5 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 The connecting frame 4 includes two parallel horizontal arms 41 spaced apart. The hook frame 5 includes two angle steels 51 respectively mounted on the horizontal arms 41. One side flange of the angle steel 51 overlaps the top of the horizontal arm 41, and the other side flange is threaded with a clamping member 52 for fixing the angle steel 51 to the corresponding horizontal arm 41. The horizontal arms 41 are made of square tubing. The connecting frame 4 includes two parallel horizontal arms 41 spaced apart, and the length direction of the horizontal arms 41 is along the arrangement direction of the two support rods 3. The two horizontal arms 41 form an installation gap for mounting the hook frame 5. The hook frame 5 is installed between the two horizontal arms 41, and the hook frame 5 includes two angle steels 51 whose length direction is along the length direction of the horizontal arms 41. One side flange of the angle steel 51 overlaps the top of the horizontal arm 41 to bear the downward force of the lifting arm 11. The other side flange of the angle steel 51 is located on the side of the cross arm 41. The fastener 63 is a bolt. The fastener 63 is threadedly connected to the flange of the angle steel 51 located on the side of the cross arm 41, so that the angle steel 51 can be fixed to the cross arm 41.

[0020] Specifically, in this embodiment, the two cross arms 41 on the connecting frame 4 and the two angle steels 51 on the hook frame 5 can limit the position of the hook frame 5 by the connecting frame 4, preventing the hook frame 5 from slipping off the connecting frame 4. At the same time, it is convenient to adjust the position of the hook frame 5 on the connecting frame 4 along the length of the connecting frame 4. After the position of the hook frame 5 is determined, the hook frame 5 is fixed to the connecting frame 4 by using the clamping member 52.

[0021] In some embodiments, the lifting arm 11 may be adopted as follows: Figure 2 The structure shown. See also Figure 2 A lifting ring 21 is installed in the middle of the lifting arm 11, and a hook 53 for hanging onto the lifting ring 21 is fixedly installed on the hook frame 5. The lifting ring 21 is installed on the top surface of the middle part of the lifting arm 11, and the hook 53 for connecting to the lifting ring 21 is fixedly installed on the hook frame 5. By adjusting the height of the connecting frame 4, the hook 53 can be hung onto the lifting ring 21, thus achieving the connection between the hook frame 5 and the lifting arm 11. After the hook 53 and the lifting ring 21 are stably connected, the connecting frame 4 is then fixed to the two support rods 3. The structure is simple and the operation is convenient.

[0022] In some embodiments, the support rod 3 may be adopted as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3A support base 31 is installed at the bottom end of the support rod 3. An adjusting screw 32 is threadedly connected between the support base 31 and the support rod 3, with the threads at both ends of the adjusting screw 32 turning in opposite directions. The support base 31 is used to support and fix the support rod 3 to the ground. Threaded holes are provided at the bottom end of the support rod 3 and the top end of the support base 31. The two ends of the adjusting screw 32 are threaded into the threaded holes at the bottom end of the support rod 3 and the top end of the support base 31, respectively, with the threads at both ends turning in opposite directions. This allows the distance between the support base 31 and the support rod 3 to be adjusted by rotating the adjusting screw 32, ensuring that the support base 31 and the support rod 3 are firmly pressed against the ground and the roof, respectively, thus guaranteeing the stability of the support rod 3's installation position.

[0023] Preferably, in this embodiment, after the support base 31 and the support rod 3 are respectively pressed against the ground and the roof, the support base 31 can be fixed to the ground or the support rod 3 can be fixed to the roof using expansion bolts. This further improves the stability of the installation position of the support rod 3. Simultaneously, it allows for fixing the support rod 3 in position using expansion bolts, facilitating the positioning of the drilling locations.

[0024] In some embodiments, the connecting frame 4 described above can be as follows: Figure 4 The structure shown. See also Figure 4 The two cross arms 41 have sleeves 42 fixedly installed at their ends. A connector 6 is detachably installed on the support rod 3, and an arc-shaped plate 7 for fixing the sleeves 42 to the connector 6 is detachably installed on the connector 6. The sleeves 42 are used to connect to the ends of the cross arms 41, realizing a fixed connection between the two cross arms 41. At the same time, the connector 6 is detachably installed on the support rod 3. The connector 6 and the arc-shaped plate 7 are clamped on the outside of the sleeves 42 to realize the connection and fixation between the connector 6 and the sleeves 42. Finally, the connector 6 is fixed to the support rod 3. The structure is simple and the operation is convenient.

[0025] In some embodiments, the connector 6 described above may be as follows: Figure 4 The structure shown. See also Figure 4 The connector 6 is threadedly connected to a tensioning member 71 for pulling the arc-shaped plate 7 towards the connector 6. The arc-shaped plate 7 has a U-shaped groove for avoiding the tensioning member 71. The tensioning member 71 is a bolt threadedly connected to the connector 6. Ear plates protrude from two opposite sides of the arc-shaped plate 7 for mounting the tensioning member 71, and U-shaped grooves are provided on the ear plates for mounting the tensioning member 71. The tensioning member 71 passes through the U-shaped groove and is threadedly connected to the connector 6. The head of the tensioning member 71 abuts against the ear plate, achieving tightening between the arc-shaped plate 7 and the connector 6, thereby effectively fixing the sleeve 42 to the connector 6.

[0026] In some embodiments, the connector 6 described above may be as follows: Figure 4 The structure shown. See also Figure 4 The connector 6 includes two clamping plates 61 hinged together. A fixing screw 62 is fixedly mounted on one clamping plate 61, and the fixing screw 62 passes through the other clamping plate 61. A fastener 63 for tightening the two clamping plates 61 is also threaded onto the fixing screw 62. The two clamping plates 61 are used to clamp the two opposite sides of the support rod 3, thereby fixing the connector 6 to the support rod 3.

[0027] Specifically, in this embodiment, one end of the two clamping plates 61 is hinged to each other, and the other end of the two clamping plates 61 clamps the support rod 3 between the two clamping plates 61 by a fixing screw 62 and a fastener 63. A fixing screw 62 is fixedly installed on one of the clamping plates 61, and an opening slot for avoiding the fixing screw 62 is provided on the other clamping plate 61. The clamping between the two clamping plates 61 can be achieved by tightening the fastener 63 onto the fixing screw 62.

[0028] Specifically, in this embodiment, a threaded hole for installing a tensioning member 71 is provided on one of the clamping plates 61, and the arc-shaped plate 7 is pulled closer to the clamping plate 61 by the tensioning member 71.

[0029] In some embodiments, the aforementioned trolley 2 may employ, as follows: Figure 1 The structure shown. See also Figure 1 The trolley 2 is slidably mounted on the lifting arm 11, and a first pull rope 81 and a second pull rope 82 are fixedly connected to both ends of the trolley 2 along the sliding direction. A rotating roller 8 is rotatably mounted on the lifting frame 1 to connect the first pull rope 81 and the second pull rope 82. The rotating roller 8 is rotatably mounted on the lifting frame 1 and is divided into a first winding section and a second winding section along the axis of the rotating roller 8. The first pull rope 81 is wound on the first winding section, and the second pull rope 82 is wound on the second winding section. The winding directions of the first pull rope 81 and the second pull rope 82 on the rotating roller 8 are opposite. Thus, when the rotating roller 8 rotates, the first pull rope 81 and the second pull rope 82 are in the pulling and releasing states, respectively. The first pull rope 81 and the second pull rope 82 are fixed to both ends of the trolley 2, thereby realizing the movement of the trolley 2 on the lifting arm 11.

[0030] Specifically, in this embodiment, guide rope wheels are rotatably provided at both ends of the lifting arm 11, and the first pull rope 81 and the second pull rope 82 pull the trolley 2 to move on the lifting arm 11 through the guidance of the guide rope wheels.

[0031] Optionally, in this embodiment, a hook is also installed on the pulley 2, the hook is connected by a third rope, and a guide roller for installing the third rope is also provided on the lifting frame 1. The third rope is wound around the guide roller to realize the operation of winding and unwinding the third rope. Both the rotating roller 8 and the guide roller are driven by a motor to rotate.

[0032] In some embodiments, the aforementioned lifting ring 21 may be adopted as follows: Figure 2 The structure shown. See also Figure 2 The lifting ring 21 is inserted into the lifting arm 11, and a limiting member 211 for abutting against the bottom of the lifting arm 11 is threaded onto the lifting ring 21. The lifting ring 21 is a U-shaped ring, with both ends of the lifting ring 21 inserted vertically into the lifting arm 11, and the limiting member 211, which is a nut, is threaded onto both ends of the lifting ring 21, and abuts against the bottom of the lifting arm 11. By rotating the limiting member 211, the lifting ring 21 can be pulled downward. After the hook 53 on the hook frame 5 is hooked onto the lifting ring 21, the lifting ring 21 can be pulled downward by adjusting the limiting member 211, so that the hook 53 can tighten the lifting ring 21, effectively improving the pulling effect on the lifting arm 11.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
