[0031] The present application provides an assembled staircase lifting platform, which can solve the problems of the prior art that the traditional steel pipe erection and walkway board laying construction are relatively cumbersome, and most of the erection is random and has a large safety hazard.

[0032] REFERENCE Figure 1The application discloses a kind of overall structure schematic diagram of assembly type stairway lifting platform, the assembly type stairway lifting platform disclosed in the application, including assembly type support frame 1, fixed lower stair 2, sliding guide rail 16 and movable upper stair 3, the height of assembly type support frame 1 is specifically set up according to the height required by actual construction site to be raised, movable upper stair 3 and fixed lower stair 2 are respectively arranged at the both ends of the length direction of the top surface of assembly type support frame 1, fixed lower stair 2 is arranged obliquely from the top surface of assembly type support frame 1 towards bottom surface, to facilitate construction personnel to climb;Sliding guide rail 16 is integrally made with the top surface of assembly type support frame 1, so that the connection of sliding guide rail 16 and assembly type support frame 1 is more closely, and then the strength of sliding guide rail 16 is improved.Sliding guide rail 16 extends outward in parallel from the top surface of assembly type support frame 1, movable upper stair 3 is slidably arranged on sliding guide rail 16, and then the connection distance of movable upper stair 3 and the upper building or upper construction platform of construction site is adjusted, which can adapt to various distances;The length of sliding guide rail 16 is less than the length of movable upper stair 3, so that movable upper stair 3 can always be fixed on the top surface of assembly type support frame 1 with a certain area during movement, and then the support strength of movable upper stair 3 is improved, so that the safety factor is higher.The problems that traditional steel pipe erection and walkway board laying construction are more complicated in the prior art, and most of the erection is random, with great safety hazards, are solved.

[0033] In order to facilitate construction personnel to climb to the operation platform 11 through the fixed lower stair 2, a fixed tread 21 is additionally provided at one end of the fixed lower stair 2 close to the operation platform 11, so as to facilitate the walking of construction personnel. In addition, railings 22 are installed on both sides of the fixed lower stair 2, so that construction personnel can hold the railings 22 when climbing the fixed lower stair 2, making the climbing process safer and more convenient to use.

[0034] The assembly type support frame 1 includes an operation platform 11, a plurality of support vertical rods 12 and a structural reinforcement, the plurality of support vertical rods 12 are detachably connected to the bottom surface of the operation platform 11, in the embodiment, four support vertical rods 12 are provided and are respectively installed at the four corners of the operation platform 11, the structural reinforcement is arranged between adjacent support vertical rods 12 to improve the connection strength of the assembly type support frame 1. The sliding guide rail 16 and the fixed lower stair 2 are respectively fixed at both ends of the length direction of the support platform. A plurality of mounting bolt holes are formed at the four corners and the edges of the operation platform 11, the fixed lower stair 2 is tightly fixed at one end of the operation platform 11 by mounting bolts, and the plurality of support vertical rods 12 are connected to the bottom surface of the operation platform 11 by connecting bolts, which is simple in structure and convenient to install.

[0035] Further, the structural reinforcement includes longitudinal support clamping grooves 13 and transverse fixing rods 14. The longitudinal support clamping grooves 13 are arranged at the bottom of two adjacent support vertical rods 12 in the width direction of the operation platform 11. The longitudinal support clamping grooves 13 are provided with fixing slots for the support vertical rods 12 to pass through. Two support vertical rods 12 pass through the longitudinal support clamping grooves 13, which can temporarily limit the position of the support vertical rods 12. In order to further limit the two support vertical rods 12, bolt holes can be pre-arranged on the support vertical rods 12, and bolt holes of appropriate size can be arranged on the side of the longitudinal support clamping grooves 13, and fastening bolts are inserted to temporarily fix the longitudinal support clamping grooves 13 and the support vertical rods 12, so that the two support vertical rods 12 on the same wide side of the operation platform 11 form a stable support surface with the longitudinal support clamping grooves 13, improving the connection strength of the overall structure. The transverse fixing rods 14 are arranged between two adjacent support vertical rods 12 on the same long side of the operation platform 11, so that the operation platform 11, the four support vertical rods 12, the longitudinal support clamping grooves 13 and the transverse fixing rods 14 form a rectangular frame. The transverse fixing rods 14 can be welded to the two adjacent support vertical rods 12 or bolted to the two adjacent support vertical rods 12 to improve the connection strength of the overall assembled support frame 1.

[0036] In order to further improve the connection strength of the assembled support frame 1 and improve the safety factor during construction, the structural reinforcement also includes support counter rods 15. The support counter rods 15 are arranged obliquely between the support vertical rods 12 and the operation platform 11. In order to improve the connection strength, the support counter rods 15 are welded to the support vertical rods 12 and the operation platform 11. In other embodiments, in order to facilitate the installation and disassembly of the assembled support frame 1, the support counter rods 15 can also be installed using a bolt connection method.

[0037] In the present embodiment, the operating platform 11, the plurality of support vertical rods 12 and the structural reinforcement are all made of high-strength metal material, such as steel material. Steel not only has extremely high tensile strength and compressive strength, but also can maintain the integrity of the operating platform 11, the plurality of support vertical rods 12 and the structural reinforcement under extreme conditions. In addition, steel has good plasticity and toughness, which can absorb and disperse a large amount of energy, thereby effectively resisting impact and vibration, improving the structural strength of the operating platform 11, the plurality of support vertical rods 12 and the structural reinforcement, and prolonging the service life of the operating platform 11, the plurality of support vertical rods 12 and the structural reinforcement. In addition, the weldability and processability of steel are also very good, which facilitates accurate cutting and connection according to actual needs to meet the installation requirements of the operating platform 11, the plurality of support vertical rods 12 and the structural reinforcement. In other embodiments of the present application, the operating platform 11, the plurality of support vertical rods 12 and the structural reinforcement can also be made of aluminum alloy, titanium alloy and other materials. Although the strength of aluminum alloy is slightly inferior to that of steel, it has small density and light weight, which is very beneficial for application scenarios that need to reduce overall weight. Titanium alloy is known for its high strength, low density and good corrosion resistance, and is suitable for applications in extremely harsh environments. The selection of the specific material of the operating platform 11, the plurality of support vertical rods 12 and the structural reinforcement can be flexibly changed according to the actual application scenario.
