Description

Technical Field

[0001] This utility model belongs to the field of construction engineering equipment technology, specifically a construction engineering material hoist. Background Technology

[0002] In construction engineering, material hoists are one of the key pieces of equipment for vertical material transportation. Currently, some material hoisting devices based on mechanical transmission and hydraulic drive have appeared on the market. However, these devices often require frequent maintenance and have limited adaptability when facing complex working conditions. Furthermore, these devices may suffer from insufficient stability and low automation during the hoisting process, making it difficult to meet the demands of modern construction sites for efficient material transportation.

[0003] For example, the Chinese invention patent (publication number: CN111452857B) discloses a "construction vehicle," which includes a hopper mechanism with a vibrating plate inside. A ball bearing assembly is fitted to the bottom of the vibrating plate. The synergistic effect of the vibrating plate and the ball bearings effectively solves the problem of sand adhering to the bottom of the hopper, thereby improving dumping efficiency. However, this design primarily addresses the dumping problem during sand transportation and does not address the stability and automated control during material lifting. Its lifting capacity is particularly limited when dealing with heavy or irregular materials.

[0004] For example, the Chinese invention patent (publication number: CN113247073B) discloses a "construction vehicle," whose specification states that it includes a vehicle body equipped with a braking assembly and a support pressing assembly. The cooperation of these two components can stop the vehicle body from sliding, thereby protecting transport personnel and preventing material spillage and waste. While this design improves transport safety, its function mainly focuses on braking control during transport, lacking optimized design for material lifting, making it particularly difficult to provide an efficient lifting solution in high-rise building construction.

[0005] The aforementioned problems indicate that traditional material hoisting equipment currently on the market has limited support for the demand for efficient and stable material transportation under complex working conditions. Therefore, this utility model proposes a novel intelligent, automatically adjustable flow rate material hoist for construction engineering to optimize the shortcomings of existing technologies and provide a more intelligent, efficient, and adaptable solution to changing environments. Utility Model Content

[0006] The purpose of this invention is to solve the problems of insufficient stability, low degree of automation and limited adaptability of existing material hoists under complex working conditions, while optimizing the efficiency and safety of material transportation.

[0007] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a material hoist for construction engineering, comprising a hoisting structure including a lifting component and an adaptive adjustment component. A fixed support is provided at the top of the lifting component, and the adaptive adjustment component is located inside the lifting component. The vertical transport and stable control of materials are achieved through the coordinated action of the lifting component and the adaptive adjustment component. Supporting guides are provided on both sides of the lifting component, and sliding adjustment components are located inside the supporting guides.

[0008] The adaptive adjustment component includes a support platform, with several elastic support columns fixedly installed at the bottom of the support platform. A pressure sensor is installed between each elastic support column, and a signal transmission cable is installed on the surface of the pressure sensor. The lifting component includes two drive wheels located on both sides of the support platform. When the drive wheels run on the track, they monitor the weight distribution of the material on the support platform in real time through the pressure sensor and transmit the data to the control system to adjust the power output during the lifting process.

[0009] As a preferred technical solution of this utility model, the fixed bracket includes a support beam, and the top of the support beam has two mounting holes communicating with the bottom of the support beam. The two drive wheels are respectively connected to the inside of the two mounting holes through bearings.

[0010] As a preferred technical solution of this utility model, the lifting assembly further includes two auxiliary brackets welded and fixed to the bottom end of the support beam. The two drive wheels are respectively rotatably connected to the outside of the two auxiliary brackets through bushings. The bearing platform is slidably connected to the guide rail between the two auxiliary brackets through a slide rail. Each of the two drive wheels is provided with a limiting block welded and fixed to the support beam on its outside.

[0011] As a preferred technical solution of this utility model, the supporting guide includes a guide rod, which is used to cooperate with the sliding adjustment member.

[0012] As a preferred technical solution of this utility model, the sliding adjustment component includes a sliding sleeve that is slidably sleeved outside the guide rod, and the sliding sleeve is fixedly connected to the support beam by bolts.

[0013] As a preferred technical solution of this utility model, an anti-slip toothed rack is fixedly provided on the circumferential side of the drive wheel, and the anti-slip toothed rack is made of a highly wear-resistant material.

[0014] As a preferred technical solution of this utility model, a shock-absorbing spring is embedded inside the guide rod. One end of the shock-absorbing spring contacts the inner wall of the sliding sleeve, and the other end abuts against the end of the guide rod.

[0015] As a preferred technical solution of this utility model, the top of the support beam is provided with an inspection port that communicates with the bottom of the support beam, and the inspection port is located between two mounting holes.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] By incorporating adaptive adjustment and lifting components, the instability of traditional material hoists when handling heavy or irregular materials is addressed. Specifically, the load-bearing platform, through the combination of elastic support columns and pressure sensors, can monitor the material weight distribution in real time and adjust the power output during the lifting process, preventing equipment tilting or damage due to uneven load. Furthermore, the design of the drive wheels and rails, combined with the application of anti-slip racks, improves the equipment's grip and stability during operation, thereby reducing the risk of slippage.

[0018] The design of the supporting guide components and sliding adjustment components further enhances the operational stability of the equipment. The shock-absorbing springs inside the guide rods absorb vibration energy during equipment operation, reducing the impact of external shocks and extending the equipment's service life. The combined design of fixed supports and auxiliary supports ensures the rigidity and strength of the overall structure, enabling it to meet the high-intensity material transportation needs in high-rise building construction.

[0019] In summary, this utility model, through a series of innovative mechanical structure designs, significantly improves the adaptability and operating efficiency of the material hoist under complex working conditions, while reducing maintenance costs, providing a more intelligent, efficient and safe solution for modern construction engineering.

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.

[0029] This utility model relates to a material hoist for construction engineering, the overall structure of which is as follows: Figure 1 As shown, the invention includes a lifting structure 1, a lifting assembly 2, an adaptive adjustment assembly 3, and a fixed support 4. The lifting assembly 2 and the adaptive adjustment assembly 3 work together to achieve vertical transport and stable control of materials, while the fixed support 4 provides support and a mounting foundation for the overall structure. The specific embodiments of this invention will be described in detail below with reference to the accompanying drawings.

[0030] The lifting structure 1 is the core component of this invention, which, together with the lifting assembly 2 and the adaptive adjustment assembly 3, completes the material transport task. The lifting assembly 2 is located in the main body of the lifting structure 1, and its top is equipped with a fixed bracket 4. The fixed bracket 4 includes a support beam 12, with two mounting holes 13 at its top. Two drive wheels 9 are connected to the two mounting holes 13 via bearings. Anti-slip racks 18 are fixedly installed on the circumferential side of the drive wheels 9. The anti-slip racks 18 are made of highly wear-resistant material, which enhances grip during operation. When the drive wheels 9 run on the track, limit blocks 15 are provided on their outer sides. The limit blocks 15 are welded and fixed to the support beam 12 to prevent the drive wheels 9 from deviating or leaving the track during operation. In addition, the lifting assembly 2 also includes two auxiliary brackets 14, which are welded and fixed to the bottom end of the support beam 12. The two drive wheels 9 are rotatably connected to the outer sides of the two auxiliary brackets 14 via bushings. The carrying platform 5 is slidably connected to the guide rails between the two auxiliary brackets 14 via slide rails, thereby achieving smooth lifting and lowering of the carrying platform 5.

[0031] The adaptive adjustment component 3 is located inside the lifting component 2. Its core component is the support platform 5. Several elastic support columns 6 are fixedly installed at the bottom of the support platform 5. A pressure sensor 7 is installed between each elastic support column 6. A signal transmission cable 8 is installed on the surface of the pressure sensor 7, and the signal transmission cable 8 transmits the data collected by the pressure sensor 7 to the control system. The specific structure of the support platform 5 can be found in [reference needed]. Figure 3 Elastic support columns 6 are evenly distributed at the bottom of the support platform 5, and their number and position are adjusted according to the design load of the support platform 5. Pressure sensors 7 are used to monitor the weight distribution of materials on the support platform 5 in real time. When materials are placed on the support platform 5, pressure sensors 7 obtain the weight distribution information of materials by detecting the force on the elastic support columns 6, and transmit the data to the control system to adjust the power output during the lifting process. When the drive wheel 9 runs on the track, the pressure sensors 7 monitor the weight distribution of materials on the support platform 5 in real time. The control system dynamically adjusts the power output of the drive wheel 9 according to the received data to ensure that the support platform 5 remains balanced during the lifting process.

[0032] Support guide members 10 are located on both sides of the lifting assembly 2. Each support guide member 10 contains a sliding adjustment member 11. The support guide member 10 includes a guide rod 16, and the sliding adjustment member 11 includes a sliding sleeve 17 that is slidably fitted onto the outside of the guide rod 16. The sliding sleeve 17 is fixedly connected to the support beam 12 by bolts. A shock-absorbing spring 19 is embedded inside the guide rod 16. One end of the shock-absorbing spring 19 contacts the inner wall of the sliding sleeve 17, and the other end abuts against the end of the guide rod 16. The function of the shock-absorbing spring 19 is to absorb vibration energy during equipment operation, reducing the impact of external shocks on the equipment, thereby improving the operational stability of the equipment and extending its service life. The design of the support guide member 10 and the sliding adjustment member 11 further enhances the overall stability of the equipment. Their cooperation method can be found in [reference needed]. Figure 2 .

[0033] The structural design of the fixed bracket 4 is as follows: Figure 5 As shown, the top of the support beam 12 has an inspection port 20 that communicates with the bottom of the support beam 12. The inspection port 20 is located between two mounting holes 13, which facilitates the maintenance and repair of the equipment. The combined design of the fixed bracket 4 and the auxiliary bracket 14 ensures the rigidity and strength of the overall structure, enabling it to meet the high-intensity material transportation needs in the construction of high-rise buildings.

[0034] The working principle of this utility model is as follows: When materials need to be lifted from the ground to a higher position, they are first placed on the carrying platform 5. The elastic support column 6 and pressure sensor 7 at the bottom of the carrying platform 5 then begin to operate. The pressure sensor 7 obtains the weight distribution information of the material by detecting the force on the elastic support column 6 and transmits the data to the control system via the signal transmission cable 8. The control system dynamically adjusts the power output of the drive wheel 9 based on the received data to ensure that the carrying platform 5 remains balanced during the lifting process. When the drive wheel 9 runs along the track, the anti-slip rack 18 on its circumferential side enhances the grip, while the limit block 15 prevents the drive wheel 9 from deviating or leaving the track. The cooperative design of the support guide 10 and the sliding adjustment component 11 ensures that the carrying platform 5 remains stable during the lifting process. The shock-absorbing spring 19 inside the guide rod 16 absorbs vibration energy, reducing the impact of external impacts on the equipment. The entire lifting process is monitored and adjusted in real time by the control system to ensure the safety and efficiency of material transportation.

[0035] This invention is applicable to various construction engineering scenarios, and has significant advantages, especially in the construction of high-rise buildings. Through the above structural design, this invention can effectively solve the problem of insufficient stability of traditional material hoists when dealing with heavy or irregular materials, while improving the automation level and adaptability of the equipment, providing a more intelligent, efficient and safe solution for modern construction engineering.

[0036] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model will be further explained below in conjunction with a specific application scenario.

[0037] Scene Description

[0038] In high-rise building construction, it is necessary to lift a batch of heavy building materials from the ground to a working platform 30 meters high. In this scenario, the materials include regular steel bars and irregular precast concrete components, and the construction site environment is complex, with certain vibration and impact disturbances. To ensure the safety, stability, and efficiency of material transportation, the construction material hoisting machine provided by this utility model is adopted.

[0039] Step 1: Material loading and initial testing

[0040] First, the operator places the steel bars or precast concrete components to be transported onto the support platform 5. Several elastic support columns 6 are evenly distributed at the bottom of the support platform 5 to accommodate materials of different shapes and weight distributions. After the material is placed, the pressure sensor 7 detects the force exerted on the elastic support columns 6 to obtain the weight distribution information of the material. The signal transmission cable 8 transmits the collected data to the control system in real time.

[0041] During this process, the design of the elastic support column 6 effectively disperses the pressure of the material on the support platform 5, preventing equipment damage due to localized overload. Simultaneously, the placement of the pressure sensor 7 is optimized to ensure complete coverage of the bottom area of ​​the support platform 5, thereby accurately sensing the weight distribution of the material. The control system's algorithm calculates the material's center of gravity based on the received data and adjusts the power output parameters of the drive wheel 9 accordingly, ensuring balance during subsequent lifting.

[0042] Step Two: Start Lifting and Power Adjustment

[0043] After the control system completes data processing, the drive wheel 9 begins to run along the track, driving the support platform 5 upward. An anti-slip rack 18 is fixedly installed on the circumferential side of the drive wheel 9. The anti-slip rack 18 is made of highly wear-resistant material, which enhances grip during operation and prevents slippage. A limiting block 15 is welded and fixed to the outer side of the support beam 12 to limit the lateral displacement of the drive wheel 9, further improving operational stability.

[0044] During the lifting process, pressure sensor 7 continuously monitors changes in the weight distribution of materials on the support platform 5. For example, when irregular materials experience slight displacement due to vibration, pressure sensor 7 can quickly detect this change and transmit the updated data to the control system via signal transmission cable 8. The control system dynamically adjusts the power output ratio of the two drive wheels 9 based on the new data to ensure that the support platform 5 remains level at all times, avoiding the risk of tilting due to a shift in the center of gravity.

[0045] Step 3: Vibration Reduction and Guiding Protection

[0046] As the support platform 5 gradually rises, vibrations and impacts from the external environment may affect the operation of the equipment. At this time, the support guide 10 and the sliding adjustment component 11 work together to ensure the smooth lifting and lowering of the support platform 5. Specifically, the sliding sleeve 17 in the sliding adjustment component 11 slides along the guide rod 16, and the shock-absorbing spring 19 embedded between the sliding sleeve 17 and the guide rod 16 absorbs external vibration energy and reduces the impact on the equipment.

[0047] The shock-absorbing spring 19 is designed with progressive stiffness characteristics, providing stronger cushioning when subjected to large impacts while maintaining low resistance during normal operation, thus balancing shock absorption and operational efficiency. Furthermore, the coordinated design of the sliding adjustment component 11 and the support guide component 10 ensures that the load-bearing platform 5 maintains precise vertical positioning during lifting, avoiding safety hazards caused by lateral swaying.

[0048] Step 4: Reaching the target height and unloading

[0049] As the carrying platform 5 approaches the target height, the control system reduces the power output of the drive wheels 9, causing the carrying platform 5 to gradually decelerate until it comes to a complete stop. At this point, the operator can unload the material onto the working platform using the auxiliary device on the carrying platform 5. Throughout the lifting process, the combined design of the fixed support 4 and the auxiliary support 14 provides sufficient structural strength to ensure the reliability of the equipment under high load conditions.

[0050] The access port 20 facilitates routine maintenance and troubleshooting by operators. For example, when the drive wheel 9 or anti-slip rack 18 wears out, operators can quickly replace the relevant parts through the access port 20, thereby reducing downtime and improving equipment efficiency.

[0051] Supplement to the principles of technical effect implementation

[0052] This invention significantly improves the performance of the material hoist through a series of innovative designs. For example, the combination of the elastic support column 6 and the pressure sensor 7 enables real-time monitoring of material weight distribution, fundamentally solving the tilting problem caused by uneven load in traditional equipment. The design of the anti-slip rack 18 and the limiting block 15 enhances the operational stability of the equipment under complex working conditions and reduces the risk of slippage and deviation. In addition, the application of the shock-absorbing spring 19 not only improves the equipment's impact resistance but also extends its service life, making it more suitable for high-intensity construction environments.

[0053] In summary, through the specific implementation of the above steps, this utility model successfully solves the problems of insufficient stability, low degree of automation, and limited adaptability of existing material hoists under complex working conditions, providing a more intelligent, efficient, and safe solution for modern construction engineering.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
