[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a liftable support leg elevator shaft construction platform, including a construction platform 1;

[0025] The bottom front side of the construction platform 1 is equipped with a support component for supporting the construction platform 1, and the support component includes two fixing frames 2.

[0026] An adjustment component for adjusting the position of the construction platform 1 is installed on the outside of the fixed frame 2;

[0027] The bottom of the construction platform 1 is equipped with a drive component for providing power input to the adjustment component;

[0028] The supporting component also includes two movable frames 23. Each movable frame 23 has a buffer block 24 fixedly connected to both ends of its outer wall. The two fixed frames 2 are respectively located on the bottom sides of the construction platform 1. The fixed frames 2 have an expansion groove 21 inside and buffer grooves 22 on both sides inside. The buffer grooves 22 and the expansion grooves 21 are connected. The movable frames 23 and the buffer blocks 24 are slidably connected inside the expansion grooves 21 and the buffer grooves 22, respectively.

[0029] Through the above technical solution, the equipment uses the construction platform 1 as the construction platform, which needs to ensure that there is enough space for personnel to operate. The construction platform 1 is customized according to the size of the elevator shaft to ensure the stability of the construction platform 1 installation and avoid gaps that may cause safety hazards. The moving frame 23 and the fixed frame 2 provide front support for the construction platform 1. During the movement of the moving frame 23 and the fixed frame 2, two semi-circular buffer blocks 24 are added to the outer wall of the moving frame 23 to increase the friction between the two and avoid the moving frame 23 and the fixed frame 2 being too smooth, which would cause the support plate 3 to have a large supporting pressure.

[0030] Please see Figure 1 , Figure 2 and Figure 3 The drive assembly includes two support plates 3 located on the outside of the fixed frame 2. The outer walls of the two support plates 3 are fixedly connected to adjacent sides of the outer walls of the two support plates 3. The rear end of the outer wall of the fixed frame 2 is fixedly connected to a fixed seat 31. Cylinders 33 are installed on both sides of the top of the fixed seat 31. The output end of the cylinder 33 is fixedly connected to the bottom wall of the fixed block 32.

[0031] The adjustment assembly includes a slide groove 4 formed on the outer wall of the fixed frame 2. The two slide grooves 4 are respectively located on one side of the two fixed frames 2 and are far apart from each other. A fixed rod 42 is fixedly connected to the bottom of the outer wall of the support plate 3. A movable block 41 is fixedly connected to the outer wall of the fixed rod 42. The movable block 41 is slidably connected to the inner wall of the slide groove 4, and the size of the movable block 41 is adapted to the size of the inner wall of the slide groove 4.

[0032] Through the above technical solution, the cylinder 33 is the core power input component in the entire equipment. The cylinder 33 drives the fixed block 32 and the construction platform 1 to move up and down synchronously, so that the construction platform 1 can move up and down synchronously. In turn, it can be used in conjunction with the bearing component to adjust the position of the construction platform 1 in the vertical direction. The two ends of the slide 4 need to extend to the inside of the fixed frame 2 to limit the movement block 41 and prevent it from falling off. The design of the movement block 41 can ensure that the end of the support plate 3 moves synchronously.

[0033] Please see Figure 1 , Figure 2 and Figure 5 The outer rear end of the fixed frame 2 is fixedly connected to a tripod 5, and the top wall of the tripod 5 is fixedly connected to the bottom wall of the support plate 3.

[0034] Multiple reinforcing rods 8 are fixedly connected to the adjacent sides of the outer walls of the two fixing frames 2 and the support plate 3;

[0035] The inner bottom of the fixed frame 2 is provided with a receiving block 6. The size of the receiving block 6 is adapted to the size of the movable frame 23 and the buffer block 24. Springs 7 are fixedly connected to both sides of the inner bottom wall of the fixed frame 2. The top of the springs 7 is fixedly connected to the bottom wall of the receiving block 6.

[0036] Through the above technical solution, the fixed frame 2 and the fixed base 31 are reinforced by the tripod 5 to ensure the stability of the fixed base 31 installation; the two fixed frames 2 and the support plate 3 are connected by multiple reinforcing rods 8 to further ensure the overall stability of the device; at the bottom of the fixed frame 2, a support block 6 is connected by a spring 7. The support block 6 needs to be compatible with the size of the moving frame 23 and the buffer block 24. When the construction platform 1 is at risk of falling, the moving frame 23 falls on the surface of the support block 6, and the impact force is buffered by the spring 7 to improve safety.

[0037] Working Principle: First, the main body of the elevator shaft construction platform in this application consists of a construction platform 1, a fixed frame 2, and a support plate 3. The construction platform 1, as a platform for personnel to carry out construction, needs to be adapted to the spatial dimensions of the elevator shaft to ensure construction safety. The fixed frame 2 is positioned on the floor to be constructed by a bottom locking block. When a small adjustment of the height of the construction platform 1 is required, the cylinder 33 at the top of the fixed base 31 is activated. The cylinder 33 drives the fixed block 32 to move up and down. Since the fixed block 32 and the support plate 3 are fixedly connected, the support plates 3 on both sides move up and down synchronously with the fixed block 32. During the movement of the support plate 3, its end drives the moving block 41 to slide on the inner wall of the slide groove 4 through the fixed rod 42, thereby ensuring the normal sliding of the support plate 3. The slide groove 4 needs to extend to the inner side of the fixed frame 2. The size of the moving block 41 is adapted to the inner wall of the slide groove 4. The extended slide groove 4 can limit the moving block 41 to prevent it from sliding. During the process, the platform detaches, and through the coordinated action of the drive component and the adjustment component, the construction platform 1 tends to move up and down. Since the bottom walls of the construction platform 1 are fixedly connected to the movable frame 23 and the support plate 3 respectively, when the construction platform 1 tends to move, it will drive the movable frame 23 to move on the inner wall of the fixed frame 2. At the same time, a buffer structure is provided on the outer side of the fixed frame 2 and the movable frame 23. During the up and down movement of the movable frame 23 following the construction platform 1, the sliding between the buffer block 24 and the buffer groove 22 increases the friction between the movable frame 23 and the fixed frame 2, thereby improving the support effect of the load-bearing component on the construction platform 1. Through the drive component, power is input, so that the adjustment component and the load-bearing component drive the support plate 3 and the movable frame 23 to move synchronously, thereby realizing the vertical movement of the construction platform 1. This allows for small-scale position adjustments even after the construction platform is fixed, improving construction efficiency and construction safety.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
