Description

Technical Field

[0001] The utility model belongs to the technical field of building material lifting, in particular to a building material lifting device for high-rise building construction. Background Art

[0002] In high-rise building construction, efficient and safe material transportation is crucial. At present, the common practice is to use a material lifting device, especially a wire rope to pull the hopper, to achieve vertical lifting of materials. For example, the utility model patent document with announcement number CN217732526 U introduces a material lifting device for super high-rise building construction.

[0003] However, this type of wire rope traction hoist has exposed some significant problems in actual application. As the material is lifted to high altitude, the high-altitude airflow becomes a factor that cannot be ignored. When the high-altitude airflow directly acts on the material box, the material box often becomes unstable, and this instability will cause the wire rope connected to it to swing. This swing will accelerate the local wear of the wire rope and shorten its service life.

[0004] What is more serious is that due to the lack of an effective and uniform retracting and releasing mechanism, the wire rope is prone to uneven tension during the lifting process. This uneven tension distribution will further increase the risk of damage and breakage of the wire rope, seriously threatening the stability and safety of the entire material lifting system.

[0005] Therefore, it is very necessary to invent a building material lifting device for high-rise building construction. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a construction material lifting device for high-rise building construction, comprising a lifting base, a uniform protection steel cable mechanism, a steel cable, a winding roller and a lifting motor, wherein two lifting bases are provided, the uniform protection steel cable mechanism is installed between the two lifting bases, and the uniform protection steel cable mechanism is passed through by the steel cable; the steel cable is wound on the winding roller, the winding roller is fixedly connected to the output end of the lifting motor, and the winding roller and the lifting motor are fixedly installed on the two lifting bases;

[0007] The uniform protection steel cable mechanism includes a reciprocating screw, a limit steel cable disc, a limit block, a buffer, a mounting base and a rolling ball. There are two reciprocating screws in total, and the two reciprocating screws are rotatably mounted on the two lifting bases; the limit steel cable disc is installed on the reciprocating screw, and the limit block is arranged below the two limit steel cable discs. A number of the rolling balls are rotatably mounted in the limit block, and the steel cable passes through the two limit steel cable discs; the two ends of the buffer are rotatably connected to the limit block and the mounting base respectively, and the mounting base is fixedly connected to one of the lifting bases.

[0008] Preferably, a closed spiral groove is provided on the reciprocating screw, and the limiting steel cable disc relies on the closed spiral groove to perform reciprocating motion. A channel allowing the steel cable to pass through is formed between the two limiting steel cable discs, and the steel cable is in close contact with the surface of the limiting steel cable disc, which can drive the limiting steel cable disc to rotate.

[0009] Preferably, the limit block is a structure with an outer square and an inner circle, and a ball cavity is provided on the limit block to allow the rolling balls to roll, and a plurality of the rolling balls are in close contact with the surface of the steel cable.

[0010] Preferably, the buffer is composed of an oil storage cylinder assembly, a hydraulic rod and a spring, and the buffer is a hydraulic throttling shock absorber. There are two buffers in total, which are located below the reciprocating screw.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model innovatively introduces a uniform protection steel cable mechanism. When the steel cable passes between two limit steel cable discs, the limit steel cable disc is driven to rotate, so that the limit steel cable disc can make regular reciprocating motion, thereby achieving uniform dispersion of the steel cable tension, and effectively preventing damage or breakage of the steel cable caused by uneven tension. At the same time, the use of the buffer significantly reduces the impact and vibration generated by the steel cable during the retraction and release process, especially when the tension suddenly changes or the steel cable swings, and its ability to absorb impact energy ensures the stable operation of the system. In addition, the close contact between the limit steel cable disc and the steel cable and the rotation driven by the movement of the steel cable ensure uniform support and guidance of the steel cable, thereby improving the movement stability and service life. The rolling ball installed in the limit block further reduces the friction between the steel cable and the limit block, reduces wear and energy loss, and makes the movement of the steel cable smoother.

[0020] As attached Figure 1 To Attachment Figure 3 As shown:

[0021] The utility model provides a construction material lifting device for high-rise building construction, comprising a lifting base 1, a uniform protection steel cable mechanism 2, a steel cable 3, a winding roller 4 and a lifting motor 5. The lifting base 1 is provided with two, and the uniform protection steel cable mechanism 2 is installed between the two lifting bases 1, and the uniform protection steel cable mechanism 2 is passed through by the steel cable 3; the steel cable 3 is wound on the winding roller 4, and the winding roller 4 is fixedly connected to the output end of the lifting motor 5, and the winding roller 4 and the lifting motor 5 are fixedly installed on the two lifting bases 1. The winding roller 4 is driven by the lifting motor 5, and the steel cable 3 is retracted and released by controlling the rotation of the motor, thereby controlling the lifting and lowering of the material box.

[0022] The uniform protection cable mechanism 2 includes a reciprocating screw 21, a limit cable disc 22, a limit block 23, a buffer 24, a mounting base 25 and a ball 26. There are two reciprocating screws 21, which are rotatably mounted on the two lifting bases 1. The limit cable disc 22 is mounted on the reciprocating screw 21, and the limit block 23 is arranged below the two limit cable discs 22. A plurality of balls 26 are rotatably mounted in the limit block 23, and the cable 3 passes through the two limit cable discs 22. The two ends of the buffer 24 are rotatably connected to the limit block 23 and the mounting base 25, respectively, and the mounting base 25 is fixedly connected to one of the lifting bases 1. The uniform protection cable mechanism 2 performs regular reciprocating motion, thereby realizing uniform dispersion of the tension of the cable 3, and effectively preventing the cable 3 from being damaged or broken due to uneven tension. At the same time, the impact and vibration generated by the steel cable 3 during the retraction and release process are reduced, especially when the tension suddenly changes or the steel cable 3 swings, its ability to absorb impact energy ensures the stable operation of the system.

[0023] Embodiment 1:

[0024] Specifically, a closed spiral groove is provided on the reciprocating screw 21, and the limit cable disc 22 performs reciprocating motion by means of the closed spiral groove. The spiral groove not only provides a precise motion trajectory for the limit cable disc 22, but also ensures the stability and reliability of its reciprocating motion. When the steel cable 3 drives the limit cable disc 22 to rotate, the spiral groove guides the limit cable disc 22 to perform reciprocating motion. This design ensures that the steel cable 3 is always uniformly supported and guided when passing between the two limit cable discs 22. A channel is formed between the two limit cable discs 22 to allow the steel cable 3 to pass through, which not only ensures the smooth passage of the steel cable, but more importantly, the steel cable 3 is in close contact with the surface of the limit cable disc 22. This close contact relationship not only enhances the stability of the steel cable, but also when the steel cable 3 is raised or lowered, its movement can stably drive the limit cable disc 22 to rotate.

[0025] Specifically, the stopper 23 is a structure with a square outside and a round inside, ensuring that the steel cable 3 maintains a stable position during the lifting and lowering process. The inner round structure, i.e., the ball cavity, is used to accommodate the rolling balls 26. These ball cavities are precisely arranged according to a certain layout and spacing to ensure that the rolling balls 26 can roll freely therein, and a number of the rolling balls 26 are in close contact with the surface of the steel cable 3. When the steel cable 3 contacts the stopper 23 during the lifting and lowering process, the rolling balls 26 can roll to reduce the friction between the steel cable 3. This rolling contact not only reduces the wear of the steel cable 3, but also reduces the noise and energy loss during the operation of the system.

[0026] Specifically, the buffer 24 is composed of an oil storage cylinder assembly, a hydraulic rod and a spring. The buffer 24 is a hydraulic throttling shock absorber. Two buffers 24 are provided, which are located below the reciprocating screw 21. The rotating connection at both ends of the buffer 24 and its own elasticity can move with the steel cable 3, and ensure that it performs a buffering operation on the swinging steel cable 3 without affecting the uniform winding of the steel cable 3.

[0027] Embodiment 2:

[0028] In the startup phase, the lifting motor 5 starts to work according to the control signal, driving the winding roller 4 to rotate, thereby controlling the release or winding of the steel cable 3. During the lifting process, the steel cable 3 will pass through the channel formed between the two limit steel cable discs 22. The two limit steel cable discs 22 are in close contact with the steel cable 3, so the lifting and lowering movement of the steel cable 3 will drive the limit steel cable discs 22 to rotate. The closed spiral groove opened on the reciprocating screw 21 provides a precise motion trajectory for the limit steel cable disc 22, allowing it to reciprocate. This reciprocating motion ensures that the steel cable 3 is always evenly supported and guided when passing between the two limit steel cable discs 22.

[0029] During the lifting and lowering process of the steel cable 3, if it contacts the limit block 23, the internal rolling ball 26 will roll freely in the ball cavity. This rolling contact reduces the friction between the steel cable 3 and the limit block 23, reduces the wear of the steel cable 3, and reduces the noise and energy loss during the operation of the system.

[0030] Especially when the tension suddenly changes or the steel cable 3 swings, the buffer 24 plays a key role. It adopts a hydraulic throttling shock absorber design, and through the coordinated action of the oil storage cylinder assembly, the hydraulic rod and the spring, it can absorb the impact energy, reduce the vibration of the steel cable 3, and ensure the stable operation of the system. The rotating connection at both ends of the buffer 24 and its own elasticity allow it to move with the steel cable 3 without affecting the uniform winding of the steel cable 3.

[0031] Finally, by controlling the rotation of the lifting motor 5, the retraction and extension of the steel cable 3 is controlled, thereby accurately controlling the lifting speed and position of the material box. This design ensures the stable lifting of the steel cable 3 and the safe transportation of the material box by uniformly protecting the reciprocating motion of the steel cable mechanism 2, the friction reduction effect of the limit block and the rolling ball, and the shock absorption function of the buffer, thereby improving the reliability and safety of the system, extending the service life of the steel cable, and reducing maintenance costs.

[0032] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
