Description

Technical Field

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

[0002] A construction material hoist is a type of vertical transportation equipment widely used on construction sites, primarily for lifting and transporting goods such as construction materials and equipment. A search revealed that patent publication number CN201620482401.X discloses a construction material hoist. While this device is capable of lifting materials on a construction site, the internal space of the frame is narrow during use. This narrow space directly makes it difficult for operators to move freely when loading and unloading materials, especially for large or heavy materials, increasing the difficulty and danger of operation. Due to space limitations, operators may need to spend more time and energy to complete material loading and unloading tasks, thereby reducing overall construction efficiency. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides a construction material hoist that solves the problems raised in the background art.

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] A construction material hoist comprises a frame, a guide wheel assembly is mounted on the frame, a winding wheel assembly is mounted at the bottom end of the frame, a lifting bracket is movably mounted on the frame via the guide wheel assembly and the winding wheel assembly, and the guide wheel assembly, the lifting bracket and the winding wheel assembly are connected via a steel cable transmission.

[0006] The lifting bracket is provided with a bracket body, and one end of the bracket body facing away from the winding wheel group is fastened with a steel cable, the other end of the steel cable on the bracket body is connected and fixed to the first winding wheel, the lifting bracket is located in the frame and is slidably mounted with a lifting slider, the upper end of the lifting slider is fastened with a steel cable to the upper end of the bracket body on the side close to the winding wheel group, and the bottom end of the lifting slider is fastened with a steel cable to the bottom end of the bracket body on the side close to the winding wheel group;

[0007] A telescopic shelf is installed on the lifting bracket, and the telescopic shelf is provided with a bottom plate, and a first slide plate and a second slide plate are slidably installed on the bottom plate. A power wheel is installed at the bottom end of the bottom plate, and a sliding motor is installed on one side of the telescopic shelf, and the sliding motor is transmission-connected to the power wheel.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the winding wheel assembly is provided with a power shaft, the first winding wheel and the second winding wheel are located on the power shaft, and the winding wheel assembly is transmission-connected to an external power device via the power shaft.

[0010] The beneficial effects of adopting the above further scheme are:

[0011] As the core transmission component, the power shaft efficiently transmits power from the external power unit to the first and second reels. This direct transmission method reduces power loss during transmission and improves overall efficiency. Mounting the first and second reels on the same power shaft makes the overall reel assembly more compact. This not only saves space but also optimizes the overall design of the elevator. Because both the first and second reels are mounted on the power shaft, they receive power and rotate synchronously. This synchronization is crucial for the smooth raising and lowering of the lifting bracket, ensuring the stability and safety of the material during the lifting process.

[0012] Furthermore, the guide wheel group is provided with a first guide wheel, a second guide wheel, a third guide wheel, a fourth guide wheel and a fifth guide wheel at the top of the frame, and the guide wheel group is provided with a sixth guide wheel at one side of the winding wheel group.

[0013] The beneficial effects of adopting the above further scheme are:

[0014] The installation of multiple guide wheels (first through sixth) provides multiple support points for the cable, ensuring a stable cable path and tension during transmission, reducing transmission instability caused by sway or deviation. The guide wheel assembly precisely guides the cable, ensuring the lifting bracket moves smoothly along the predetermined trajectory during lifting, enhancing transmission accuracy.

[0015] Furthermore, the steel cable between the bracket body and the first winding wheel is supported by the first guide wheel and the fourth guide wheel.

[0016] The beneficial effects of adopting the above further scheme are:

[0017] The cable is supported by the first and fourth guide pulleys, forming a multi-point fixed transmission path. This design reduces vibration and deflection during transmission, improving transmission stability. Multi-point support disperses vibration and impact forces generated by the cable during transmission, making the transmission process smoother and reducing noise and wear caused by vibration.

[0018] Furthermore, the steel cable between the upper end of the bracket body and the lifting slider is supported by the third guide wheel, and the steel cable between the upper end of the lifting slider and the second winding wheel is supported by the second guide wheel and the fifth guide wheel.

[0019] The beneficial effects of adopting the above further scheme are:

[0020] The steel cable is supported by multiple guide pulleys (the third, second, and fifth guide pulleys), ensuring stability and accuracy during transmission. This design reduces vibration and deflection, thereby improving transmission stability and reducing safety hazards caused by such vibrations. The multi-point support design prevents derailment or breakage of the steel cable during transmission, ensuring the safe operation of the material hoist. The support of multiple guide pulleys ensures more even force distribution on the steel cable during transmission, reducing wear and damage caused by excessive force at a single point.

[0021] Furthermore, the steel cable between the lower end of the bracket body and the lifting slider is supported by a sixth guide wheel.

[0022] The beneficial effects of adopting the above further scheme are:

[0023] The sixth guide wheel provides an additional support point for the steel cable between the lower end of the bracket body and the lifting slider, enhancing the stability of the entire hoist structure. This design helps reduce shaking and deviation caused by uneven weight distribution or external factors (such as wind) during lifting and lowering. With the support of the sixth guide wheel, the force distribution of the steel cable during the transmission process is more even. This helps to reduce wear and damage caused by excessive force at a single point, thereby extending the service life of the steel cable and guide wheel. The sixth guide wheel ensures the precise guidance of the steel cable during the transmission process, allowing the lifting slider to move smoothly along the predetermined trajectory. This helps to improve transmission efficiency and reduce transmission errors caused by deviation or shaking.

[0024] Furthermore, support wheels are installed at both ends of the base plate and the first skateboard, and the support wheels at both ends of the base plate are connected to the power wheels through a synchronous belt transmission, and the support wheels at both ends of the first skateboard are also connected through a synchronous belt transmission. The synchronous belt of the base plate is connected and fixed to the first skateboard through a third pressure block, and the synchronous belt on the first skateboard is connected and fixed to the second skateboard and the base plate through a first pressure block and a second pressure block respectively.

[0025] The beneficial effects of adopting the above further scheme are:

[0026] The use of a synchronous belt as a transmission element ensures synchronized movement between the base plate, the first slide, and the second slide. The synchronous belt offers advantages such as high transmission efficiency, precise transmission ratios, and smooth transmission, enabling the telescopic rack to maintain consistent coordination between its components during extension and contraction. The support wheels provide stable support for the telescopic rack, while the synchronous belt connects these wheels to achieve efficient transmission. This combination results in a compact and stable structure for the telescopic rack, ensuring optimal operation under various operating conditions.

[0027] The utility model provides a construction material hoist with the following beneficial effects:

[0028] The dual reel design (primary and secondary) allows the lifting bracket to be lifted simultaneously from both ends, increasing lifting stability and efficiency. This design reduces the potential for tilting or shaking caused by single-point lifting, improving construction safety.

[0029] The meticulous design of the guide pulley assembly, including multiple guide pulleys (such as the first through sixth guide pulleys), ensures the stability and accuracy of the cable during transmission. These guide pulleys not only support the cable but also guide it along the intended path, reducing friction and wear and extending the service life of the equipment.

[0030] The introduction of the lifting slider makes the movement of the lifting bracket in the frame more stable. The connection between the steel cable and the lifting slider realizes the synchronous lifting of both ends of the bracket body, further enhancing the stability of the lifting process.

[0031] The telescopic racking design achieves automatic expansion and contraction through the coordinated operation of components such as the sliding motor, power pulley, and timing belt. This design not only improves material storage and retrieval efficiency, but also reduces manual operation and labor intensity. Furthermore, the use of a tensioner ensures the timing belt remains taut, improving transmission efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] See also Figures 1 to 4 As shown, the embodiment provided by the utility model:

[0042] Example 1

[0043] A construction material hoist includes a frame 2, a guide wheel assembly 3 mounted on the frame 2, a reel assembly 6 mounted at the bottom end of the frame 2, the reel assembly 6 having a power shaft 601, a first reel 602 and a second reel 603 mounted on the power shaft 601, the reel assembly 6 being connected to an external power device via the power shaft 601, the power device driving the power shaft 601 to drive the first reel 602 and the second reel 603 to reel in a steel cable 1, the power shaft 601 being a core transmission component, being highly efficient in that it can seamlessly connect to an external power source, directly and efficiently transmitting power to the first reel 602 and the second reel 603, significantly reducing energy loss during power transmission and thereby improving overall operating efficiency. Integrating the dual reels on the same power shaft 601 achieves an extremely compact structure for the reel assembly 6, which not only optimizes space utilization but also promotes refinement and efficiency in the overall design of the hoist. Under this layout, the two winding wheels receive power and rotate synchronously, ensuring a high degree of synchronization of the lifting bracket 4 in vertical movement, which is the key to ensuring the stability and safety of material lifting. The lifting bracket 4 is movably installed on the frame 2 through the guide wheel group 3 and the winding wheel group 6. The guide wheel group 3, the lifting bracket 4 and the winding wheel group 6 are connected by the steel cable 1. The guide wheel group 3 is located at the top of the frame 2 and is provided with a first guide wheel 301, a second guide wheel 302, a third guide wheel 303, a fourth guide wheel 304 and a fifth guide wheel 305. The guide wheel group 3 is located on one side of the winding wheel group 6 and is provided with a sixth guide wheel 306. The multi-guide wheel configuration (covering the first guide wheel 301 to the sixth guide wheel 306) builds a stable support network for the steel cable 1, effectively maintaining the stability and tension consistency of the steel cable 1 on the transmission path, and significantly suppressing the transmission instability caused by shaking or offset. The guide wheel group 3 ensures the smooth operation of the lifting bracket 4 along the preset path by accurately planning the trajectory of the steel cable 1, greatly improving the transmission accuracy and reliability. The lifting bracket 4 is provided with a bracket body 402, and the end of the bracket body 402 facing away from the winding wheel group 6 is fastened with a steel cable 1, and the other end of the steel cable 1 on the bracket body 402 is connected and fixed to the first winding wheel 602. The steel cable 1 is wound up by the first winding wheel 602 to lift the end of the bracket body 402 facing away from the winding wheel group 6. The steel cable 1 between the bracket body 402 and the first winding wheel 602 is supported by the first guide wheel 301 and the fourth guide wheel 304. The steel cable 1 is fixedly supported at multiple points by the first guide wheel 301 and the fourth guide wheel 304 to construct a stable transmission channel, effectively reducing shaking and deviation during transmission, and significantly improving the stability of transmission.The second guide wheel 305 is used to support the lifting mechanism 402, and the lifting mechanism 403 is used to support the lifting mechanism 402. This layout effectively prevents the risk of the steel cable 1 derailing or breaking, providing a solid guarantee for the safe operation of the material hoist. At the same time, multi-point support balances the force on the steel cable 1, avoids increased wear caused by single-point overload, and extends the service life of the steel cable 1 and the guide wheel. The bottom end of the lifting slider 401 and the bottom end of the bracket body 402 near the winding wheel group 6 are fastened with the steel cable 1. The steel cable 1 between the lower end of the bracket body 402 and the lifting slider 401 is supported by the sixth guide wheel 306. The sixth guide wheel 306 serves as an additional support point for the steel cable 1 between the lower end of the bracket body 402 and the lifting slider 401, significantly enhancing the overall stability of the hoist structure. Its design effectively resists shaking caused by uneven weight distribution or external environmental factors (such as wind load), further improves the uniformity of force during the transmission process, and extends the service life of key components. The sixth guide wheel 306 also ensures the precise guidance of the steel cable 1 transmission, promotes the smooth movement of the lifting slider 401, and improves transmission efficiency and accuracy.

[0044] Example 2

[0045] In order to improve the efficiency of material storage and retrieval, for example, Figures 1 to 4As shown, the present invention also includes: a telescopic shelf 5 is installed on the lifting bracket 4, and the telescopic shelf 5 is provided with a bottom plate 501, and a first slide 504 and a second slide 506 are slidably installed on the bottom plate 501, and a power wheel 509 is installed at the bottom end of the bottom plate 501, and a sliding motor 511 is installed on one side of the telescopic shelf 5, and the sliding motor 511 is transmission-connected to the power wheel 509, and support wheels 502 are installed at both ends of the bottom plate 501 and the first slide 504, and the support wheels 502 at both ends of the bottom plate 501 are transmission-connected to the power wheel 509 through a synchronous belt 512, and a tensioner 510 is installed on both sides of the power wheel 509 at the bottom end of the bottom plate 501, and the synchronous belt 512 on the bottom plate 501 is kept taut by the tensioner, and the support wheels 502 at both ends of the first slide 504 are also transmission-connected by a synchronous belt 512. The synchronous belt 512 is connected to the base plate 501 and fixed to the first slide 504 via the third pressure block 508. When the synchronous belt 512 of the base plate 501 rotates, it automatically drives the first slide 504 to move. The synchronous belt 512 on the first slide 504 is connected to the second slide 506 and the base plate 501 via the first pressure block 505 and the second pressure block 507, respectively. When the first slide 504 moves, the first pressure block 505 drives the second slide 506. The synchronous belt 512 acts as a transmission medium. Its efficient, precise, and stable characteristics ensure the synchronous movement of the base plate 501, the first slide 504, and the second slide 506, achieving highly coordinated extension and retraction of the telescopic shelf 5. The perfect combination of the support wheels 502 and the synchronous belt 512 not only creates a compact and stable structural foundation, but also gives the telescopic shelf 5 excellent performance in various working conditions, providing strong support for the efficient management of construction materials.

[0046] Working principle:

[0047] An external power device (such as an electric motor) is connected to the power shaft 601 of the winding wheel group 6 through a transmission device. When the power device is started, power is transmitted to the first winding wheel 602 and the second winding wheel 603 through the power shaft 601.

[0048] The first winding wheel 602 and the second winding wheel 603 rotate under power, respectively controlling the retraction and extension of the two sets of steel cables 1. The first set of steel cables 1 is connected to the end of the bracket body 402 of the lifting bracket 4 that is away from the winding wheel group 6, and is supported by the first guide wheel 301 and the fourth guide wheel 304 to achieve the lifting of one end of the bracket body 402. The second set of steel cables 1 is connected to the upper end of the lifting slider 401 of the lifting bracket 4 and the second winding wheel 603, and is supported by the second guide wheel 302 and the fifth guide wheel 305 to achieve the synchronous lifting of the other end of the bracket body 402. The bottom end of the lifting slider 401 is also connected to the bracket body 402 by the steel cables 1, and the steel cables 1 are supported by the third guide wheel 303 and the sixth guide wheel 306 to maintain the stability of the bracket body 402.

[0049] As the first winding wheel 602 and the second winding wheel 603 rotate, the two sets of steel cables 1 are retracted and released, causing the lifting bracket 4 to vertically rise and fall in the frame 2. The lifting slider 401 slides in the frame 2 to ensure that the bracket body 402 remains stable during the lifting process.

[0050] When the telescopic shelf 5 is in the retracted state, the bottom plate 501, the first slide 504 and the second slide 506 are all in a stacked state, the power wheel 509 is stationary, the synchronous belt 512 remains taut, and the entire shelf structure is stable.

[0051] The sliding motor 511 then starts, rotating the power wheel 509. The power wheel 509 is connected to the support wheels 502 at each end of the base plate 501 via a synchronous belt 512, causing the synchronous belt 512 to begin rotating around the power wheel 509 and the support wheels 502. Simultaneously, the synchronous belt 512 on the base plate 501 is fixedly connected to the first slide 504 via the third pressure block 508. Therefore, the operation of the synchronous belt 512 drives the first slide 504. Because the support wheels 502 at each end of the first slide 504 are also connected to the synchronous belt 512, the movement of the first slide 504 is smooth and controlled.

[0052] The timing belt 512 of the first slide 504 is connected to the second slide 506 and the base plate 501 via the first pressing block 505 and the second pressing block 507. When the first slide 504 moves, the timing belt 512 of the first slide 504 drives the second slide 506 via the first pressing block 505, ensuring that the second slide 506 moves synchronously with the first slide 504. Similarly, the movement of the second slide 506 is precisely controlled by the timing belt 512, ensuring that it is coordinated with the movement of the first slide 504.

[0053] Driven continuously by the sliding motor 511, the base plate 501, first slide 504, and second slide 506 extend sequentially to the desired shelf length. Throughout this process, the synchronous belt 512 acts as a transmission medium, ensuring synchronization between each component and smooth movement. When the shelf reaches its maximum extension, the sliding motor 511 stops, and the powered wheel 509 also stops rotating, maintaining its new position.

[0054] When the shelf needs to be retracted, the sliding motor 511 rotates in the reverse direction, causing the power wheel 509 to rotate in the opposite direction, driving the synchronous belt 512 to rotate in the opposite direction. The synchronous belt 512, through its connection with each pressure block, sequentially drives the second slide 506 and the first slide 504 to move in the retracting direction, ultimately restoring the telescopic shelf 5 to its initial retracted state.
