[0003] Therefore, in view of the shortcomings existing in the above structure, it is necessary to provide a new simple ladder frame for subway section support construction to solve the above technical problems. Utility Model Content

[0004] In order to solve the technical problems that during subway section construction, ladders need to be frequently moved for construction, construction efficiency is slow, construction difficulty is large and safety factor is low, the utility model provides a simple ladder frame for subway section support construction.

[0005] The utility model adopts the following technical scheme to achieve: a simple ladder frame for subway section support construction, comprising:

[0034] A ladder frame horizontal device 2, the ladder frame horizontal device 2 is composed of steel pipes, and the ladder frame horizontal device 2 is installed at the connecting sleeve 11 to carry workers to work;

[0035] An adapting mechanism, which is arranged outside the ladder frame horizontal device 2 to abut against the pipe piece;

[0036] A brake mechanism, which is arranged at the bottom end of the ladder main device 1;

[0037] The connecting mechanism is used to connect the ladder main device 1 and the ladder horizontal device 2 and provide support.

[0038] A lower connecting angle steel 21 is symmetrically welded at the bottom end of one side of the ladder frame horizontal device 2, and the lower connecting angle steel 21 is inserted and connected in the connecting sleeve 11 for splicing and installation.

[0039] The adapting mechanism comprises a connecting slide 22, which is symmetrically arranged outside the ladder frame horizontal device 2, and a connecting rod 23 is horizontally slidably connected in the connecting slide 22, and a horizontal pulley 24 is symmetrically connected to the top of the outer side of the connecting rod 23 for rolling against the pipe piece.

[0040] The connecting mechanism includes a connecting rotating rod 25, which is symmetrically arranged on both sides of the connecting rod 23. The two groups of connecting rotating rods 25 are rotatably connected with connecting sleeves 23. The bottom ends of the two groups of connecting sleeves 23 are hollow, and the outer walls of the two groups of connecting sleeves 23 are evenly opened with connecting holes 31.

[0041] Support steel pipes 32 are inserted and connected in the two groups of connecting holes 31, and holes are evenly opened at the tops of the two groups of support steel pipes 32. Bolts 1 33 are connected at the connection between the support steel pipes 32 and the connecting holes 31 for connecting the two. Bolts 2 34 are connected at the connection between the bottom ends of the support steel pipes 32 and the outer wall of the ladder main device 1 for installing the support steel pipes 32 and supporting the ladder horizontal device 2.

[0042] The implementation principle of a simple ladder frame for subway section support construction in the embodiment of the present application is:

[0043] First, insert the lower connecting angle steel 21 corresponding to the connecting sleeve 11 into the connecting sleeve 11 to complete the installation of the ladder horizontal device 2 and the ladder main device 1. Then, after carrying the parts to the designated area, use the horizontal sliding adjustment of the connecting slide 22 and the connecting rod 23 to achieve the horizontal pulley 24 abutting against the pipe segment in the repair area. Then rotate the connecting sleeve 23 and insert the installation support steel pipe 32. When the bottom end of the support steel pipe 32 is connected to the outer wall of the ladder main device 1, use the bolt 24 to fix it. Then, use the bolt 33 again at the connection between the support steel pipe 32 and the connecting sleeve 23 to achieve the installation of the support steel pipe 32 and the connecting sleeve 23, thereby achieving the fixation of the connecting rod 23, and the triangular support of the ladder horizontal device 2 will be achieved under the connection of the support steel pipe 32.

[0044] Embodiment 2:

[0045] Combination Figure 3 Based on Example 1, this embodiment is further improved in that:

[0046] The brake mechanism includes pulley brake devices 44 symmetrically installed on both sides of the bottom end of the ladder main device 1 for connecting with the track. The steel pipes on both sides of the ladder main device 1 are vertically slidably connected with connecting rings 41, and damping is provided at the connection between the two.

[0047] The outer sides of the two groups of connecting rings 41 are connected to the connecting transverse plates 4, and the two sides of the connecting transverse plates 4 are connected to connecting recessed blocks 42. The two groups of connecting recessed blocks 42 are provided with movable floor track pulleys 43, and the inner sides of the two groups of floor track pulleys 43 are connected to the pulley brake devices 44 for braking the equipment.

[0048] The implementation principle of this embodiment is:

[0049] The connecting recessed blocks 42 on both sides are synchronously connected by the connecting cross plate 4. When braking and locking are required, the connecting cross plate 4 is pressed down, and the inner side of the driving connecting recessed block 42 abuts against the ground track pulley 43 under the sliding of the connecting ring 41 and the steel pipe of the ladder frame main device 1, thereby braking the pulley brake device 44; conversely, pulling up the connecting cross plate 4 can pull the ground track pulley 43 to move upward, and release the braking of the pulley brake device 44 by the ground track pulley 43.

[0050] Working principle:

[0051] First, insert the lower connecting angle steel 21 corresponding to the connecting sleeve 11 into the connecting sleeve 11 to complete the installation of the ladder horizontal device 2 and the ladder main device 1. Then, after carrying the parts to the designated area, use the horizontal sliding adjustment of the connecting slide 22 and the connecting rod 23 to achieve the horizontal pulley 24 abutting against the pipe segment in the repair area. Then rotate the connecting sleeve 23 and insert the installation support steel pipe 32. When the bottom end of the support steel pipe 32 is connected to the outer wall of the ladder main device 1, use the bolt 24 to fix it. Then, use the bolt 33 again at the connection between the support steel pipe 32 and the connecting sleeve 23 to achieve the installation of the support steel pipe 32 and the connecting sleeve 23, thereby achieving the fixation of the connecting rod 23, and the triangular support of the ladder horizontal device 2 will be achieved under the connection of the support steel pipe 32.

[0052] The connecting recessed blocks 42 on both sides are synchronously connected by the connecting cross plate 4. When braking and locking are required, the connecting cross plate 4 is pressed down, and the inner side of the driving connecting recessed block 42 abuts against the ground track pulley 43 under the sliding of the connecting ring 41 and the steel pipe of the ladder frame main device 1, thereby braking the pulley brake device 44; conversely, pulling up the connecting cross plate 4 can pull the ground track pulley 43 to move upward, and release the braking of the pulley brake device 44 by the ground track pulley 43, so that it can be moved according to the needs of the operation.

[0053] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
