Description

Technical Field

[0001] This utility model belongs to the technical field of construction platform for building engineering, and is particularly related to an adjustable lifting steel platform. Background Technology

[0002] Traditional steel lifting platforms have the following problems during construction:

[0003] 1. The steel pipe scaffolding erected in the elevator shaft has a low safety factor and many safety hazards. For example, the longitudinal horizontal bars and the joints of the uprights are not effectively stressed in the same time or span, or the steel pipes are not effectively stressed around the perimeter, which causes the scaffolding to be unstable and unevenly stressed, leading to collapse.

[0004] 2. Conventional lifting steel platforms are greatly affected by external factors, such as: improper formwork erection, the lateral pressure during pouring exceeds the design value of the formwork support, resulting in formwork bulging, which prevents the lifting steel platform from being installed smoothly and is prone to tilting of the operating platform, making it difficult to erect the upper operating frame. In addition, some conventional lifting platforms require pre-reserved holes for each layer, and sealing them later increases costs.

[0005] 3. Unaffected by the size of the elevator shaft, the stress point of the lifting steel platform can be changed by adjusting the oil support, which can save costs for future allocation and turnover.

[0006] 4. During the main construction of the project, the elevator shaft is a place where safety accidents are prone to occur. Generally, ground-mounted or I-beam cantilevered steel pipe scaffolding is used. Due to the high erection height, the safety hazards are greater and the cost is higher, and the operation is inconvenient. Utility Model Content

[0007] To address the problems existing in the aforementioned background technology, this utility model proposes a standardized adjustable steel operating platform, which has the advantages of safety, convenient operation, and low cost, and can be applied to elevator shafts of various sizes.

[0008] Therefore, the present invention adopts the following technical solution: an adjustable lifting steel platform, including a fixed platform and a top support mechanism. The fixed platform includes a main frame of the platform formed by welding several channel steels. The top support mechanism is provided in the channel steel grooves on both sides of the main frame of the platform. The top support mechanism includes a top support, an adjusting nut, and a lead screw. The lead screw is supported and installed by several fixed square tubes. The fixed square tubes are fixedly installed in the channel steel grooves. The adjusting nut is sleeved on the outer end of the lead screw. The top support is fixedly connected to the outer end face of the lead screw.

[0009] This utility model achieves the following beneficial effects: 1. This utility model controls the size of the steel platform by adjusting the length of the top support, and adjusts the position and limit of the top support by adjusting the nut positioning support, thus allowing adjustment according to the size of the elevator shaft and enabling reuse in different projects. This utility model has strong safety and can reduce construction safety hazards. The installation process is more convenient, reducing project construction costs. The connection form of this utility model is more reliable, and the integrity and safety are further improved. The application of the operating platform of this utility model can greatly reduce construction intensity and reduce construction safety hazards. 2. This utility model changes the problem of high material costs of traditional steel pipe scaffolding and traditional lifting steel platforms, which is not conducive to the long-term promotion and use of projects. In terms of improving efficiency: it reduces the installation time of the lifting steel platform, reduces labor costs, and improves the overall installation efficiency by 60%. In terms of safety performance: it facilitates operation by personnel in the elevator shaft area and improves the safety performance of the steel platform and the upper operating frame. In terms of cost saving: it enables the lifting steel platform to be reused. Attached Figure Description

[0012] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. The described embodiments are only for illustration and explanation of this utility model and do not constitute the only limitation of this utility model.

[0013] like Figure 1As shown, this utility model includes a fixed platform 2 and a top support mechanism 1. The fixed platform 2 comprises several channel steels welded together to form a main platform frame. Top support mechanisms 1 are installed in the channel steel grooves on both sides of the main platform frame. Each top support mechanism 1 includes a top support 11, an adjusting nut 12, and a lead screw 14. The lead screw is supported and installed by several fixed square tubes 13, which are fixedly installed within the channel steel grooves. The adjusting nut is fitted onto the outer end of the lead screw, and the top support 11 is fixedly connected to the outer end face of the lead screw. Several horizontally and vertically arranged main frame square tubes 22 are installed within the main platform frame. A steel plate 27 is laid on the top of the main platform frame. The main platform frame is supported and fixed by two support leg channel steels 23, which are positioned opposite each other on the other side of the top support mechanism 1. An inclined channel steel 24 connects the bottom of the support leg channel steel 23 to the bottom of the channel steel containing the top support mechanism 1. A supporting channel steel 25 connects the middle of the inclined channel steel 24 to the top of the support leg channel steel 23. A frame square tube 26 is connected at the midpoint between the two support leg channel steels 23. The top support 11 has a U-shaped structure with the U-shaped opening facing outwards. Two fixed square tubes 13 are welded and fixed to the channel steel. Round steel lifting rings 28 are fixedly connected to the front and rear sides of the platform main frame.

[0014] In this preferred embodiment, the materials include No. 100 channel steel, No. 20 round steel, and 5cm square tubing. A rectangular platform main frame is formed by welding four 100*48*5.3 main frame channel steels together. The welded frames should be on the same horizontal plane. 50cm*50cm main frame square tubing 8 is welded at 500mm-600mm intervals in the grooves of the main frame channel steel to create the secondary internal support skeleton. A 10mm thick steel plate 9 is welded onto the main frame. The top support mechanism 1 consists of a 100mm top support 11, a 48mm diameter adjusting nut 12, and a 600mm threaded rod 14. Two 5mm*5mm*10mm*4mm fixing square tubings are welded to the grooves on both sides of the main frame channel steel 21 on each side, spaced 150mm apart, as threaded rod support fixing points. The top support 11 is welded to the threaded rod 14, fitted with the adjusting nut 12, and then placed inside the square tubing. The frame is constructed by double-sided welding of 1500mm support channel steel 4, 3500mm diagonal channel steel, 2800mm vertical channel steel 6, and 150mm support leg channel steel 7 to the main frame channel steel 3, forming a triangular frame. A 1300mm square tube is installed inside the triangular frame. 20mm diameter round steel lifting rings are installed on the main frame channel steel 21, with each ring horizontally extending 200mm to both sides and welded to the surface of the main frame channel steel 21. This invention addresses the high material costs of traditional steel pipe scaffolding and traditional lifting steel platforms. Each project requires re-renting and processing, and steel pipe fasteners are prone to deformation and damage over time, resulting in relatively poor safety and increased costs, hindering long-term project turnover and promotion. Traditional steel operating platforms have poor turnover rates and cannot be reused for different elevator shaft sizes. The new steel lifting platform offers adjustable dimensions, high rigidity, good safety and stability, and better long-term economic benefits. Easy to operate and safe to protect, the optimized support method of the elevator shaft lifting operation platform facilitates construction operations and safety protection in the elevator shaft, thereby improving project quality and economic benefits.
