[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Construction hoists, also known as building construction elevators, outdoor elevators, or construction site hoists, are commonly used construction machinery for carrying people and goods. They are mainly used in the construction of high-rise buildings (both interior and exterior), bridges, chimneys, and other structures. A construction hoist mainly consists of a guide rail frame and a cage that moves longitudinally along the guide rail frame. The cage is used to transport workers. A transmission plate is installed at the top of the cage near the guide rail frame, and the transmission plate contains the motor, reducer, and other power mechanisms that drive the cage to move up and down.

[0024] Due to the limitations of existing technology, such as the inability to fold the components and the difficulty for a single person to assemble them, please refer to... Figures 1-5This utility model provides a convenient boom for a construction hoist. The folding arm assembly 3 can rotate along the top of the upright assembly 2, so that the entire folding arm assembly 3 can be folded to reduce the overall space occupied, making it more convenient for transportation or installation. Under the action of the ratchet 302, the folding arm can automatically be fixed in a fixed position after unfolding, without the need for other manual assistance in the installation work. Only one person is required to assemble the entire work, making it more convenient to use. The boom includes an electric rotating base 1, on which the upright assembly 2 is fixed. The folding arm assembly 3 is installed on the top of the upright assembly 2. A lifting assembly 4 is installed on one side of the folding arm assembly 3 and on the side wall of the upright assembly 2 to support the unfolded posture of the folding arm assembly 3. In use, first install the whole assembly on the hoist, then rotate the folding arm assembly 3 to unfold it to the working posture, and finally connect and fix the support assembly 5 to the folding arm assembly 3.

[0025] The existing boom is a fixed, integrated structure, resulting in a large space requirement during transportation. To solve this transportation problem, please refer to... Figure 2 The folding arm assembly 3 includes a fixed base 301 fixed to the top of the upright assembly 2. A ratchet 302 is rotatably connected inside the fixed base 301. The ratchet 302 is connected to one end of the rotating arm 303. A telescopic arm 304 is movably connected to the other end of the rotating arm 303. A guide wheel 305 is rotatably connected to the end of the telescopic arm 304 away from the rotating arm 303. Under the action of the ratchet 302, the rotating arm 303 and the telescopic arm 304 can rotate along the inner side of the fixed base 301. During transportation, the telescopic arm 304 is retracted into the rotating arm 303, and the rotating arm 303 is rotated closer to the upright assembly 2, so as to reduce the overall space occupied.

[0026] When in use, one person needs to manually lift the rotating arm 303 upwards. After the rotating arm 303 is rotated into place, another person needs to connect the support component 5 to the rotating arm 303 to fix it in place. However, this requires multiple people to work together, which has a drawback in terms of single-person assembly. To solve this drawback, please refer to... Figure 3The ratchet component 302 includes a pawl 3021 rotatably connected to the bottom of the fixed base 301. A spring plate 3022 is connected to one side of the pawl 3021. The spring plate 3022 is installed at the bottom of the fixed base 301. A lever 3023 is fixed on the side wall of the pawl 3021. The lever 3023 is movably disposed in a through hole opened on the side wall of the fixed base 301. The top of the pawl 3021 is engaged with the outer wall of the ratchet 3024. The ratchet 3024 is fixed to one end of the rotating arm 303 and rotatably connected to the fixed base 301 through a rotating shaft. After the rotating arm 303 is raised to the working position, under the cooperation of the ratchet 3024 and the pawl 3021, the pawl 3021 engages the ratchet 3024. At this time, the rotating arm 303 is restricted from rotating. The operator can release the rotating arm 303 and operate the support component 5 to support and fix the rotating arm 303. Only one person is needed to complete the entire installation operation.

[0027] In actual use, the height of the boom needs to be adjusted according to the lifting equipment. To achieve this, the boom assembly 2 includes a lower boom 201 fixed to the electric rotating base 1, and an upper boom 202 movably connected inside the lower boom 201. The side walls of both the lower boom 201 and the upper boom 202 are provided with matching adjustment holes, and pins 203 are inserted into the adjustment holes. Fixed pins 204 are inserted into both ends of the pins 203. When adjusting the overall height, the fixed pins 204 and pins 203 are removed, and then the upper boom 202 is raised and lowered to achieve the purpose of adjusting the height.

[0028] When using this device, the heavy object needs to be lifted to a certain height. To ensure successful lifting, please refer to the instructions below. Figure 1 The lifting assembly 4 includes a winding machine 401 installed on the side wall of the upright assembly 2. A wire rope 402 is connected to the winding machine 401. One end of the wire rope 402 passes around the guide frame 403 and the guide wheel 305 and is fixedly provided with a hook 404. The guide frame 403 is fixed to one side of the fixed seat 301. The winding machine 401 works and the hook 404 is pulled by the wire rope 402 to move, and the hook 404 lifts the heavy object.

[0029] When the folding arm assembly 3 is unfolded, since one end of the folding arm assembly 3 is only connected to the fixed base 301 via the ratchet 302, the ratchet 302 experiences significant stress, making it prone to damage. To improve lifting stability and prevent damage to the ratchet 302, please refer to... Figure 2 and Figure 4The support assembly 5 includes a support frame 501 rotatably connected to the side wall of the upright assembly 2. The end of the support frame 501 away from the upright assembly 2 is provided with a slot 5011, which is engaged with both ends of a double-ended screw 502. The double-ended screw 502 is inserted into the rotating arm 303, and both ends of the double-ended screw 502 are threaded with nuts 503. After the folding arm assembly 3 is unfolded, the support frame 501 is rotated so that the slot 5011 at one end is positioned on one side of the rotating arm 303. Then, the double-ended screw 502 is inserted laterally and locked with nuts 503, thereby fixing the support frame 501. After fixing, the support frame 501 can provide support and fixation for the folding arm assembly 3.

[0030] The telescopic arm 304 can extend and retract along the inside of the rotating arm 303. When retracted, it can reduce the space occupied. When extended, in order to fix the telescopic arm 304, an insertion hole adapted to the double-ended screw 502 is provided on the outer wall of the telescopic arm 304 near one end. When the double-ended screw 502 is inserted into the rotating arm 303, it is inserted into the insertion hole on the telescopic arm 304 at the same time, thus simultaneously fixing the telescopic arm 304.
