Abstract
Description
Technical Field
[0001] This utility model relates to the field of material lifting technology, and in particular to a material lifting device for low-rise building construction. Background Technology
[0002] Material lifting devices are mechanical equipment used for vertical or inclined conveying of building materials, primarily to solve material handling problems on construction sites. Their core function is to achieve safe and efficient lifting of heavy objects through a mechanical transmission system. Typical applications include low-rise building construction, decoration projects, and warehouse loading and unloading.
[0003] Conventional tower cranes and hoists require large vertical working spaces, making them unsuitable for the construction needs of low-rise buildings. Existing simple lifting devices mostly adopt fixed structures, limiting their working radius and making it difficult to meet the material conveying requirements of complex construction surfaces. Traditional hydraulic lifting equipment is prone to swaying during telescopic operations, especially during long-distance lifting, lacking effective anti-deviation mechanisms and posing safety hazards. Most equipment requires manual adjustment of direction, making it impossible to achieve automated continuous operation of loading, lifting, and unloading, severely impacting construction efficiency.
[0004] Therefore, it is essential to invent a material lifting device for the construction of low-rise buildings. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a material lifting device for low-rise building construction, solving the issues that existing material lifting equipment still suffers from inability to perform multi-stage material lifting in low-rise buildings, poor overall stability, and inability to operate continuously. A material lifting device for low-rise building construction includes a support base, a mounting frame, a rotating structure, a hydraulic cylinder, a telescopic structure, and a material bucket. The mounting frame is fixedly installed on the outside of the support base, and the rotating structure is fixedly installed on the surface of the support base. The hydraulic cylinder is installed inside the rotating structure. The telescopic structure is slidably installed inside the hydraulic cylinder, and the material bucket is installed at the top of the telescopic structure.
[0006] The mounting frame is installed on the scaffold using clips.
[0007] The rotating structure includes a support structure, a rotating platform, a rotating seat, a support frame, and a connecting base plate. The support structure is fixedly installed on the surface of the support seat, and the rotating platform is fixedly installed inside the support structure. The rotating seat is rotatably installed on the surface of the rotating platform, and the support frame is fixedly installed on the outside of the rotating seat. The connecting base plate is fixedly installed at both ends of the support frame. A hydraulic cylinder is fixedly installed inside the connecting base plate.
[0008] The telescopic structure includes a telescopic rod, a mounting platform, a support arm, a swivel buckle, and a connecting cable. The telescopic rod is slidably installed inside the hydraulic cylinder, and the mounting platform is fixedly installed on the top of the telescopic rod. The support arm is fixedly installed on the outside of the mounting platform, and the swivel buckle is rotatably installed on the outside of the support arm. The connecting cable is fixedly installed on the outside of the swivel buckle.
[0009] One end of the support arm is fixedly mounted on the stabilizer arm, and a stabilizing slide is fixedly mounted on the top of the stabilizer arm. The stabilizing slide is slidably mounted on the outer surface of the hydraulic cylinder.
[0010] The rotating seat inside the rotating structure adopts a disc-shaped steel metal structure, and the rotating seat is driven by a motor at its bottom to rotate 180 degrees on the rotating platform in one go; the rotating seat can drive the hydraulic cylinder to rotate 180 degrees in one go through the support frame and connecting base plate by its own rotation; the rotation of the rotating seat can reverse the orientation of the hydraulic cylinder.
[0011] The telescopic rod inside the telescopic structure can extend and retract inside the hydraulic cylinder. The telescopic rod is stably supported by the stabilizing arm and the stabilizing slide in a telescopic manner. The telescopic rod is in a retracted state when the hydraulic cylinder is facing down; the telescopic rod is in an extended state when the hydraulic cylinder is facing up; the rotating buckle and the connecting cable are always facing down on the surface of the support arm due to gravity, and a material bucket is fixedly installed below the connecting cable.
[0012] The rotating structure has a higher priority in driving the hydraulic cylinder to rotate than the telescopic structure. The rotating structure first drives the hydraulic cylinder to rotate upward, and then the telescopic structure extends upward. The rotation of the hydraulic cylinder and the extension and retraction of the telescopic structure cause the material bucket to be lifted in two stages.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The rotating structure of this utility model uses a 180° motor-driven rotating seat on a rotating platform to rotate the hydraulic cylinder, thereby switching its direction and completing the first stage of lifting the material bucket: when the hydraulic cylinder is facing downwards, it is suitable for low-level loading; when facing upwards, the rotation lifts the material bucket to one end, and a telescopic rod can be extended to achieve a second stage of lifting. Its support frame and connecting base plate stably transmit the rotational motion to the hydraulic cylinder, while the support structure ensures overall rigidity. This expands the horizontal operating range and ensures operational stability in low-ceilinged spaces, ultimately achieving safe and efficient material lifting through rotation.
[0015] 2. The telescopic structure of this utility model achieves vertical lifting and lowering through the sliding of a hydraulically driven telescopic rod within a hydraulic cylinder. The mounting platform and support arm at the top form a stable bearing platform, and the guiding action of the stabilizing arm and stabilizing slide ensures smooth and deviation-free lifting. The gravity-adaptive suspension system, composed of a rotating buckle and connecting cable, keeps the material bucket in a vertical position at all times. When working in conjunction with the rotating structure, it forms a two-stage lifting linkage mechanism: when the hydraulic cylinder is upward, the telescopic rod extends to complete the second stage of lifting; when downward, it automatically retracts to achieve low-level loading and unloading, thus achieving safe and efficient material conveying operations within a limited space.

[0026] The telescopic structure 5 includes a telescopic rod 51, a mounting platform 52, a support arm 53, a swivel buckle 56, and a connecting cable 57. The telescopic rod 51 is slidably mounted inside the hydraulic cylinder 4, and the mounting platform 52 is fixedly mounted on the top of the telescopic rod 51. The support arm 53 is fixedly mounted on the outside of the mounting platform 52, and the swivel buckle 56 is rotatably mounted on the outside of the support arm 53. The connecting cable 57 is fixedly mounted on the outside of the swivel buckle 56.
[0027] One end of the support arm 53 is fixedly mounted on the stabilizer arm 54, and a stabilizing slide 55 is fixedly mounted on the top end of the stabilizer arm 54. The stabilizing slide 55 is slidably mounted on the outer surface of the hydraulic cylinder 4.
[0028] The rotating seat 33 inside the rotating structure 3 adopts a disc-shaped steel metal structure, and the rotating seat 33 rotates 180 degrees at a time on the rotating table 32 driven by the motor at its bottom; the rotating seat 33 can drive the hydraulic cylinder 4 to rotate 180 degrees at a time through the support frame 34 and the connecting base plate 35 by its own rotation; the rotation of the rotating seat 33 can cause the orientation of the hydraulic cylinder 4 to reverse.
[0029] The telescopic rod 51 inside the telescopic structure 5 can extend and retract inside the hydraulic cylinder 4.

[0030] The rotating structure 3 has a higher priority than the telescopic structure 5 in driving the hydraulic cylinder 4 to rotate. The rotating structure 3 first drives the hydraulic cylinder 4 to rotate upward, and then the telescopic structure 5 extends upward. The rotation of the hydraulic cylinder 4 and the extension and retraction of the telescopic structure 5 cause the material bucket 6 to be lifted in two stages.
[0031] This material lifting device employs a coordinated working mechanism of a single-stage rotary lifting and a two-stage telescopic lifting: the rotary structure 3 first drives the hydraulic cylinder 4 to complete a 180° directional switch. When the hydraulic cylinder 4 is facing upwards, the telescopic rod 51 of the telescopic structure 5 extends under hydraulic drive, lifting the material bucket 6 via the support arm 53 and connecting cable 57. The stabilizing arm 54 and the stabilizing slide 55 form a guiding system to ensure a smooth lifting process, and the rotating buckle 56 keeps the material bucket 6 in a vertical position at all times. After lifting is complete, the hydraulic cylinder 4 returns to its downward position, and the telescopic rod 51 retracts, achieving cyclic operation. This design, through time-controlled rotation and telescopic linkage, achieves safe and efficient material conveying within a limited space.
