Description

Technical Field

[0001] This invention belongs to the field of steel support technology, and particularly relates to a loading and transportation device for steel support in foundation pits. Background Technology

[0002] As urbanization continues, multi-story, high-rise, and super high-rise buildings equipped with single-story or multi-story basements are becoming increasingly common. As the core and critical stage of building construction, the safety and efficiency of foundation construction directly determine the quality, schedule, and subsequent structural stability of the entire construction project. As the core structure to ensure the safety of foundation pit excavation, the foundation pit support system, steel supports (such as H-beams, I-beams and lattice steel columns, etc.) have become the core load-bearing components of foundation pit support in building construction projects due to their advantages such as high strength, convenient installation and recyclability. Their main function is to resist the soil pressure and water pressure on the side wall of the foundation pit and prevent the foundation pit from deforming and collapsing. Currently, in the construction of foundation pit support for building construction projects, the main methods of transporting steel supports are still hoisting, manual labor combined with simple machinery, rail transport systems, and small handling equipment. However, there is no dedicated integrated loading and transportation equipment for the loading and transfer of steel supports. Instead, it mainly relies on the separate use of ordinary loading tools and transfer equipment. This results in problems such as insufficient site adaptability, mismatch between transportation efficiency and construction period requirements, and safety risks compounded by surrounding environmental hazards. Consequently, loading and transfer are disconnected, inefficient, inaccurate, and have high safety risks. This directly restricts the improvement of steel support transportation efficiency, amplifies construction safety risks, and fails to meet the core needs of foundation pit support construction for building construction projects. Therefore, there is an urgent need to develop a hydraulic lifting type of steel support loading and transportation trolley for foundation pits, which is suitable for the construction scenarios of compact foundation pits and frequent cross-operations in building construction projects. It is specifically designed to solve the problems of low efficiency, poor accuracy, high safety risks, insufficient adaptability, and poor connection in the loading and transportation of steel supports. It can realize the integrated operation of safe, fast, and accurate loading, transportation, and alignment of steel supports, connect with existing transportation methods for various types of steel supports, improve the efficiency of the entire process of steel support transportation and installation, reduce the safety risks of foundation pit support construction, and effectively ensure the construction period, foundation construction quality, and safety of surrounding buildings in building construction projects. Summary of the Invention

Detailed Implementation

[0017] The invention will now be further described with reference to the accompanying drawings.

[0018] This invention provides a steel-supported loading and transportation device for foundation pits, such as... Figure 1 As shown, it includes: Traction components; The chassis frame has outrigger mounting brackets 2 connected to both sides. Both ends of the outrigger mounting brackets 2 are provided with outrigger foot plates 3 that are in contact with the ground. Outrigger hydraulic cylinders 4 are installed on the outrigger foot plates 3. Steering assembly 6 includes a steering tie rod 601. One end of the steering tie rod 601 is connected to the traction assembly, and the other end is connected to a steering reinforcing beam 603 and an actuating beam 604. The steering reinforcing beam 603 and the actuating beam 604 are both vertically connected to the steering tie rod 601. Both ends of the steering reinforcing beam 603 are sleeved on the steering column 606. Both ends of the actuating beam 604 are connected to the actuating small beam 607 through a small beam column 608. The actuating small beam 607 and the steering reinforcing beam 603 are both sleeved on the steering column 606. A steering wheel 5 is also connected to one side of the steering column 606, and a support wheel 25 is also connected to the end of the chassis frame away from the steering wheel 5. The lifting scissor lift structure is installed on the top of the chassis frame. The lifting scissor lift structure can extend and retract in the vertical direction and is also equipped with a load-bearing work platform 24. The load-bearing work platform 24 is used to load the foundation pit steel support 2406. Specifically, such as Figure 1 and Figure 4 As shown, the traction assembly includes a traction rod 102. One end of the traction rod 102 is provided with a traction ring 101, which is used to connect with an external drive component. The other end is connected to a steering rod 601. The end of the traction rod 102 away from the traction ring 101 is provided with a rotating bearing inner ring 103. The rotating bearing inner ring 103 is connected to a rotating bearing outer ring 104. The rotating bearing outer ring 104 is connected to a fixed support 105. A connecting column 106 is provided inside the fixed support 105. One end of the steering rod 601 is sleeved on the connecting column 106. In this embodiment, as Figure 5 As shown, the steering tie rod 601 is connected to the steering reinforcing crossbeam 603 through the first crossbeam column 602. Both the steering tie rod 601 and the steering reinforcing crossbeam 603 are sleeved on the first crossbeam column 602. The steering tie rod 601 is connected to the actuating crossbeam 604 through the second crossbeam column 605. Both the steering tie rod 601 and the actuating crossbeam 604 are sleeved on the second crossbeam column 605. It should be noted that in this embodiment, during transportation, an electric hoist, small loader, or excavator fixed to the installation location of the steel support is used to connect to the traction component. The traction component drives the steering tie rod 601 to swing left and right, thereby causing the actuating beam 604 to actuate, which in turn drives the actuating beam 607 to guide the steering wheel 5, thus completing the steering of the trolley. This allows the steel support to be transported safely, quickly, and accurately to the installation point. Both the steering wheel 5 and the support wheel 25 are large-size off-road tires, which enable the loading trolley to have excellent grip and off-road capability, overcoming the limitations of complex ground conditions in the foundation pit on transportation operations. After the steel support reaches the installation point, the outrigger hydraulic cylinder 4 actuates, lifting the entire trolley off the ground to form a wide and stable support surface, ensuring the steel support is securely positioned. During the lifting process, the support stabilizes the vehicle body and prevents overturning. After the outriggers are in place and form a stable support system, the lifting scissor lift structure accurately lifts the foundation pit steel support 2406 loaded in the bearing operation platform 24 to the installation position to complete the installation. That is, the entire process of transporting and lifting the steel support does not require manual participation in heavy physical labor such as pushing and adjusting. This can significantly shorten the operation cycle of transporting the steel support from the bottom of the foundation pit to the installation point, reduce the time spent on connecting each process, significantly improve the efficiency of the entire process of transporting and installing the steel support, reduce labor costs, and rely on the stability and precise guidance of mechanical traction to achieve precise alignment and stable placement of the steel support at the installation point, effectively avoiding positioning deviations caused by manual adjustment and ensuring installation accuracy. In one embodiment, such as Figure 1 As shown, the chassis frame includes a lower frame 7 and an upper frame 13. The lower frame 7 and the upper frame 13 are connected by multiple chassis support columns 9. The outrigger fixing frame 2 is connected to the lower frame 7, and the lifting scissor structure is connected to the upper frame 13. Specifically, such as Figure 6 As shown, a hydraulic power unit 8 for outriggers is also installed on the lower frame 7. The hydraulic power unit 8 for outriggers includes a control cabinet 802 and a hydraulic oil pump 801. The hydraulic oil pump 801 is equipped with a hydraulic oil gauge 803. The hydraulic oil pump 801 is connected to the hydraulic cylinder 4 of the outriggers. Under the action of the hydraulic power unit 8 for outriggers, the outrigger foot plate 3 can be symmetrically unfolded and closely attached to the ground of the pit to form a stable and reliable support force system. This system can effectively resist the overturning moment generated during the lifting of the steel support and effectively prevent the steel support from overturning, shifting and other safety hazards, thus ensuring the safety of operation in all aspects. In one embodiment, such as Figure 2 and 7 As shown, the lifting scissor lift structure includes a support base 14 and bottom support rods 17 disposed at both ends of the support base 14. Slide grooves are provided on both side plates of the support base 14, and track baffles 15 are provided on both the upper and lower sides of the slide grooves to form a sliding track 16.

A connecting bearing 1702 is also provided on the rod body 1703. A track groove 1704 is formed between the scissor lift sliding wheel 1701 and the connecting bearing 1702. The scissor lift sliding wheel 1701 is disposed in the sliding track 16, and the track groove 1704 contacts the track baffle 15. Furthermore, such as Figure 3 As shown, the lifting scissor structure also includes multiple scissor support rods 18 connected to each other in the vertical direction. The scissor support rod 18 at the bottom is hinged to the connecting bearing 1702. Two adjacent scissor support rods 18 are hinged to each other through the scissor connecting crossbar 20. Two scissor support rods 18 at the same height and on the same side are cross-connected to each other. A scissor support pin 19 is provided at the cross connection point. Specifically, a scissor hydraulic cylinder lug 21 is also provided on the scissor connecting crossbar 20 between two adjacent scissor support rods 18. The two adjacent scissor hydraulic cylinder lugs 21 are connected by a scissor hydraulic cylinder 22. A scissor hydraulic power unit 10 is also provided on the lower frame 7. The scissor hydraulic power unit 10 includes a scissor hydraulic pump 801 connected to the scissor hydraulic cylinder 22. In one embodiment, such as Figure 8As shown, the carrying operation platform 24 includes an operation platform plate 2405 and vertical baffles 2402 on both sides of the operation platform plate 2405. The pit steel support 2406 is set between the vertical baffles 2402. The bottom of the operation platform plate 2405 is also provided with mutually perpendicular horizontal support beams 2404 and longitudinal support beams 2403. The top of the vertical baffles 2402 is also provided with a water-stopping retaining wall 2401. The horizontal support beams 2404 and longitudinal support beams 2403 are connected to the scissor lift rod 18 located at the top. It should be noted that the lifting scissor lift structure in this embodiment has the technical advantages of flexible and adjustable stroke, smooth lifting, and good synchronization. It can flexibly adjust the lifting height according to the different installation height requirements of the steel supports in the foundation pit support of building construction projects, accurately complete the lifting and alignment of steel supports at different elevations, ensure the precise matching of the installation interface between the steel supports and the support structure, lay a solid foundation for the subsequent installation and fixing of the steel supports, further improve the installation quality of foundation pit support, and adapt to the complex working scenarios and diverse installation requirements in the foundation pit of building construction projects.
