Specific embodiments
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work fall within the scope of protection of the present invention.
[0022] Embodiment 1
[0023] As Figure 1 , Figure 2 shown, it includes a template body 1. One side of the template body 1 is movably connected to a column 2. A fixed rail assembly 3 is provided on the inner wall of the column 2. A connecting block 5 is fixedly connected to the bottom end of the column 2. An independent lifting assembly 4 is provided inside the column 2. The shape of the connecting block 5 is an isosceles trapezoid.
[0024] In this embodiment, the fixed rail assembly 3 includes a connecting rod 6. One end of the connecting rod 6 is fixedly connected to the side surface of the template body 1. The other end of the connecting rod 6 is fixedly connected to a mounting bracket 7. A pulley 8 is installed inside the mounting bracket 7. Four connecting rods 6 are distributed at equal angles on one side of the template body 1.
[0025] In this embodiment, a square hole 9 is opened on the inner wall of the column 2. Both sides of the mounting bracket 7 are in contact with the inner wall of the square hole 9. A sliding groove 11 is opened inside the square hole 9. The pulley 8 is slidably connected to the sliding groove 11. Both sides of the pulley 8 are in contact with the inside of the sliding groove 11.
[0026] In this embodiment, a connecting groove 10 is opened at one end of the column 2. The shape of the connecting groove 10 is the same as that of the connecting block 5. The connecting groove 10 and the connecting block 5 form a mortise and tenon structure. The surface of the connecting block 5 is relatively rough to increase the friction force. The connection between the connecting block 5 and the connecting groove 10 is further strengthened by bolts.
[0027] Embodiment 2
[0028] As Figure 3 , Figure 4 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes
[0029] In this embodiment, the self-lifting component 4 includes a housing 12. The housing 12 is movably connected to the inner side of the column 2. Hydraulic push rods 13 are installed on the inner walls at both ends of the housing 12. A fixed block 14 is fixedly connected to one side of the housing 12. A hydraulic jacking device body 15 is provided inside the fixed block 14. Both ends of the housing 12 are slidably connected inside the column 2.
[0030] In this embodiment, engaging grooves 16 are formed in the inner wall of the column 2. The shape of the output end of the hydraulic push rod 13 is the same as that of the engaging groove 16. The output end of the hydraulic push rod 13 and the inner wall of the engaging groove 16 form an engaging structure. A plurality of engaging grooves 16 are equidistantly distributed inside the column 2.
[0031] Working principle: When using this device, first, according to the user's needs, the column 2 is fixedly connected to the exterior wall of the building. The inner and outer formworks are set through the formwork body 1. When the formwork body 1 needs to climb, through the mutual cooperation between the fixed-rail component 3 and the column 2, the vertical movement of the formwork body 1 can be made more precise, preventing the position from shifting and reducing the generation of errors. The formwork body 1 is connected to the mounting frame 7 through the connecting rod 6. The mounting frame 7 is slidably connected in the square hole 9 inside the column 2. When the formwork body 1 moves up or down, the pulley 8 inside the mounting frame 7 slides inside the chute 11, making the vertical movement of the formwork body 1 proceed smoothly. When it is necessary to lift the formwork body 1 to a higher area, tenon and mortise connection can be carried out between the connecting block 5 at the bottom end of the column 2 and the connecting groove 10 at the top end of another column 2. Then, the connection between the connecting block 5 and the connecting groove 10 is strengthened by bolts. During the lifting movement of the formwork body 1, the self-lifting component 4 can reduce the downtime of the device and improve work efficiency. The output end of the hydraulic jacking device body 15 is fixedly connected to the bottom end of the formwork body 1. The formwork body 1 is jacked up by the hydraulic jacking device body 15. When jacking up, the two groups of housings 12 inside the fixed block 14 move autonomously. The hydraulic push rods 13 at both ends of the inner wall of the upper housing 12 work. The output end of the hydraulic push rod 13 disengages from the engaging groove 16 inside the column 2. The hydraulic push rods 13 at both ends of the inner wall of the lower housing 12 work. The output end of the hydraulic push rod 13 engages with the engaging groove 16 inside the column 2. Therefore, when the hydraulic jacking device body 15 jacks up, the upper housing 12 can slide inside the column 2. When moving a certain distance, the upper hydraulic push rod 13 engages with the engaging groove 16, and the lower hydraulic push rod 13 disengages from the engaging groove 16. When the hydraulic jacking device body 15 works again, the lower housing 12 will be lifted. By repeating this process, the formwork body 1 can perform self-climbing without extra steps.
[0032] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
