[0001] This utility model belongs to the field of construction engineering technology, and in particular relates to a lifting device for construction engineering. Background Technology

[0002] Construction engineering refers to the physical engineering projects formed by constructing various types of buildings, such as houses. During the construction process, various mechanical equipment is required to assist in the construction, among which lifting equipment is particularly crucial. Construction often involves heavy tools and materials such as steel bars and concrete components. Lifting equipment can suspend items on ropes and then lift the ropes through reeling wheels, which can transport items from low to high places during construction, effectively solving the problem of vertical transportation. This not only greatly improves construction efficiency but also provides important support for the construction of complex projects such as high-rise buildings.

[0003] However, existing lifting equipment is not convenient for managing the wound ropes during use. During frequent winding and unwinding, the ropes are prone to twisting and kinking, which not only affects the normal operation of the lifting equipment, but also increases the risk of rope breakage and objects falling from a height.

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.

[0026] Please see Figure 1-7 As shown, this utility model is a lifting device for construction engineering, including a lifting arm 101, and further including: a cable management part 2, which is installed on the left side of the lifting arm 101; and a rotating part 3, which is located at the bottom of the lifting arm 101.

[0027] The cable management unit 2 includes a cable management assembly 21, which is fixedly connected to the left side of the lifting arm 101; and a winding assembly 22, which is disposed inside the cable management assembly 21. The cable management assembly 21 includes a bracket 211 fixedly connected to the left side of the lifting arm 101. A reciprocating screw 212 is rotatably connected to the inner wall of the bracket 211. A slider 213 is slidably connected to the inner wall of the bracket 211. A limit plate 214 is fixedly connected to the inner wall of the bracket 211. A bracket 215 is slidably connected to the inner wall of the slider 213. Four springs 216 are fixedly connected to the bottom of the bracket 215. The bottoms of the four springs 216 are all fixedly connected to the slider 213. The reciprocating screw 212 passes through the cable management assembly. The bracket 211 and slider 213 are connected by a threaded connection between the outer wall of the reciprocating screw 212 and the slider 213. The winding assembly 22 includes a rotating shaft 221 rotatably connected to the inner wall of the bracket 211. A second bracket 222 is fixedly connected to the front side of the bracket 211.

A rope winding component is provided on the outer wall of the rotating shaft 221. A transmission component is provided on the rear side of the bracket 211. The rotating shaft 221 passes through the bracket 211. The rope winding component includes a winding wheel 224 fixedly connected to the outer wall of the rotating shaft 221. A rope 225 is wound around the inner wall of the winding wheel 224. A hook 226 is fixedly connected to the left end of cable 225; a rotating shaft 221 passes through a winding reel 224, and the left end of cable 225 passes between bracket 215 and slider 213, then passes between limiting plate 214 and bracket 211. The transmission components include two synchronous pulleys 227 located on the rear side of bracket 211, with a synchronous belt 228 fitted on the outer wall of each pulley 227, and both pulleys 227 are adapted to the synchronous belt 228; a reciprocating screw 212 passes through the left synchronous pulley 227, and its outer wall is fixedly connected to the left synchronous pulley 227; a rotating shaft 221 passes through the right synchronous pulley 227, and its outer wall is fixedly connected to the right synchronous pulley. 227 is fixedly connected. By setting up the cable management unit 2, the motor 223 drives the rotating shaft 221 to rotate, so that the rope 225 is wound up. At the same time, the synchronous pulley 227 and the synchronous belt 228 drive the reciprocating screw 212 to rotate, so that the slider drives the rope 225 to slide back and forth evenly in front of the winding wheel 224. The limit plate 214 regulates the movement path of the rope 225. The spring 216 provides a buffer for the rope 225 when the slider 213 moves. This effectively solves the problem that the rope 225 is easy to twist and fold during the winding and unwinding process of traditional lifting equipment, ensures the normal operation of the lifting equipment, reduces the risk of items falling from a height due to the breakage of the rope 225, and significantly improves the safety and reliability of lifting operations.

[0028] The rotating part 3 includes a rotating assembly 31, which is installed at the bottom of the lifting boom 101; and a fixing assembly 32, which is disposed inside the rotating assembly 31. The rotating assembly 31 provides support for the lifting boom 101, while the fixing assembly 32 restricts the rotation of the lifting boom 101. The rotating assembly 31 includes a turntable 311 fixedly connected to the bottom of the lifting boom 101, a base 312 at the bottom of the turntable 311, and a rotating shaft 313 fixedly connected to the bottom of the turntable 311. The outer wall of the turntable 311 is rotatably connected to the base 312, which is fixed to the floor of the building. The fixing assembly 32 includes a locking block 321 slidably connected to the inner wall of the base 312, a spring 322 fixedly connected to the bottom of the locking block 321, and a limit plate 323 fixedly connected to the outer wall of the rotating shaft 313. The bottom of the lifting arm 101 is fixedly connected to the base 312. The second rotating shaft 313 passes through the limiting plate 323. The limiting plate 323 is a disc with several grooves. The shape of the locking block 321 is adapted to the limiting plate 323. By setting the rotating part 3, the rotating plate 311 and the second rotating shaft 313 cooperate with the base 312 to provide flexible rotation support for the lifting arm 101, so that the lifting arm 101 can drive the object to rotate around the second rotating shaft 313. The function of the locking block 321 and the limiting plate 323 is to allow the workers to easily unlock and lock the lifting arm 101 by stepping on the locking block 321. The object is moved to the base by the cable management part 2, rotated to the surface of the base 312 by the lifting arm 101, and then removed. This can prevent the object from falling off the hook 226 during the lifting process, thereby further improving the safety and reliability of the lifting operation.

[0029] A specific application of this embodiment is as follows: In use, the base 312 can be fixed to the floor of a high-rise building, and then items can be hung on the hook 226. Subsequently, the motor 223 is started, causing its output shaft to drive the rotating shaft 221 to rotate, thereby driving the rope 225 to be wound up through the winding wheel 224. When the rotating shaft 221 rotates, it will drive the reciprocating screw 212 to rotate under the action of the two synchronous pulleys 227 and the synchronous belt 228. When the reciprocating screw 212 rotates, it will drive the slider 213 to slide under the restriction of the bracket 211, thereby driving the rope 225 to slide back and forth evenly in front of the winding wheel 224. The rope 225 will move under the restriction of the limiting plate 214. When the slider 213 moves away from the limiting plate 214, the rope 225 will apply pressure to the bracket 215, causing the spring 216 to compress and generate elastic force. The action of the hook 226 will provide a buffer for the movement of the rope 225. Finally, after the rope 225 is wound up, it will move the item to the top of the base 312 through the hook 226. At this time, the worker can step on the locking block 321 with his foot to slide it into the base 312 and apply pressure to the second spring 322 to generate elasticity. At this time, the left protrusion of the locking block 321 will move away from the limiting plate 323, thereby unlocking the restriction of the second rotating shaft 313. At this time, the lifting arm 101 can be rotated by hand to make it rotate the item around the second rotating shaft 313 to both sides of the locking block 321 through the cable management part 2. Then the locking block 321 can be released. At this time, the locking block 321 will lock the limiting plate 323 under the action of the elasticity of the second spring 322. At this time, the item can be removed from the first spring 216 and placed on the base 312. Then the lifting arm 101 can be reversed through the rotating part 3 to reset the device.
