[0023] This application provides a safety ladder for tying reinforcing bars on a slope.
[0024] like Figure 1 and Figure 2 As shown, a safety ladder for tying reinforcing bars on a slope includes a telescopic ladder 1 and multiple support components 2. The support components 2 are mounted on the step crossbars 11 of the telescopic ladder 1 via sliding components 3. Multiple step crossbars 11 are located between two adjacent support components 2. The sliding component 3 includes a sleeve 31, a sliding block 32, and a bolt 33. The sleeve 31 is fixed to the step crossbars 11, and the axial direction of the sleeve 31 is parallel to the length direction of the telescopic ladder 1. The bottom end of the sleeve 31 is closed. The sliding block 32 is slidably located inside the sleeve 31. A through groove 34 is provided on the side wall of the sleeve 31. A connecting block 35 extending out of the through groove 34 is provided on the sliding block 32. The connecting block 35 is connected to the support components 2. The bolt 33 is threadedly connected to the top end of the sleeve 31. The length direction of the bolt 33 is parallel to the axial direction of the sleeve 31. The end of the bolt 33 extending into the sleeve 31 is used to abut against the sliding block 32 to limit the highest position of the sliding block 32.
[0025] Each of the support components 2 includes at least one support leg 21. The length direction of the support leg 21 is perpendicular to the length direction of the telescopic ladder 1 and the length direction of the step bar 11. The end of the support leg 21 away from the sliding block 32 abuts against the slope surface, while the side of the support leg 21 facing the bottom of the telescopic ladder 1 abuts against the transverse steel bar.
[0026] In this embodiment of the application, when the slope is reinforced with steel bars, the safety ladder is placed against the slope, so that the ends of the support legs 21 on different step crossbars 11 abut against the slope, and the side of the support legs 21 facing the bottom of the telescopic ladder 1 abuts against the transverse steel bars. The safety ladder hangs on the transverse steel bars on the slope through the support legs 21, and at the same time uses the support legs 21 to rest against the slope, so as to ensure the stability of the safety ladder and reduce the force on the steel bars. Since the spacing of the transverse reinforcing bars varies with different slopes, the support legs 21 of this application are installed on the step bar 11 via the sliding assembly 3. When the spacing between the sides of two adjacent support legs 21 facing the bottom of the telescopic ladder 1 is not exactly equal to the spacing of the corresponding two transverse reinforcing bars, the highest position of the sliding block 32 is limited by adjusting the length of the bolt 33 extending into the sleeve 31. When placing the safety ladder, each support leg 21 is positioned between two adjacent transverse reinforcing bars, and then the safety ladder is moved downward so that the support legs 21 abut against the transverse reinforcing bars. When the support legs 21 are at their highest position, the end of each support leg 21 abuts against the slope, and the side of the support leg 21 facing the bottom of the telescopic ladder 1 abuts against the transverse reinforcing bars, ensuring stable support for the safety ladder.
[0027] like Figure 3 and Figure 4 As shown, the top end of the sleeve 31 is open, the through groove 34 penetrates the top surface of the sleeve 31, and the top of the sleeve 31 is threadedly connected to a limiting ring 4, which is fitted onto the outer periphery of the sleeve 31. The design of the top opening of the sleeve 31 and the through groove 34 penetrating the top surface of the sleeve 31 allows the sliding block 32 to enter the sleeve 31, facilitating the assembly and disassembly of the support component 2. At the same time, the limiting ring 4 prevents the top opening of the sleeve 31 from expanding and deforming due to the presence of the through groove 34. In this embodiment, the sleeve 31 is fixedly mounted on the pedal crossbar 11 by a mounting piece 36, which is fixed to the pedal crossbar 11 by screws. The mounting piece 36 is welded to the outer wall of the sleeve 31. The support leg 21 is an angle steel, and the end of the angle steel is fitted with an anti-slip sleeve or has anti-slip texture.
[0028] In one embodiment, the top opening of the sleeve 31 is provided with a mounting plate 42, and the side wall of the mounting plate 42 is provided with a limiting block 43 protruding in the direction of travel. The opening section of the sleeve 31 is provided with a limiting groove 44 for embedding the limiting block 43. The mounting plate 42 is connected to the sleeve 31. The mounting plate 42 is provided with a threaded hole for threaded connection with the bolt 33. The limiting ring 4 is integrally provided with a pressure ring 41. After the limiting ring 4 and the sleeve 31 are threadedly connected, the pressure ring 41 is pressed against the mounting plate 42 and the opening section of the sleeve 31.
[0029] The length of the sliding block 32 along the axial direction of the sleeve 31 is 50-80% of the length of the internal cavity of the sleeve 31. The side wall of the sliding block 32 is provided with ball bearings.
[0030] A spring 37 is provided between the sliding block 32 and the bottom wall of the sleeve 31, and the spring 37 is in a compressed state. The spring 37 ensures that the sliding block 32 is always in contact with the bolt 33, improving the efficiency of placing the safety ladder, and also facilitating the measurement of the distance between the two support legs 21 at their highest limit positions.
[0031] Each support component 2 includes two support legs 21, and each sliding component 3 includes two sleeves 31, two sliding blocks 32 and two bolts 33, with the support legs 21 and sliding blocks 32 on the same footrest crossbar 11 corresponding one-to-one.
[0032] The telescopic ladder 1 is a single-sided telescopic straight ladder, comprising a bottom section 12 and multiple movable sections 13. The bottom section 12 includes two support columns 14 and two step bars 11 located between the two columns. Each movable section 13 includes a column and step bars 11. The column of the lowest movable section 13 is slidably mounted within the support column 14. In two adjacent movable sections 13, the column at the upper telescopic bottom end is slidably mounted within the column at the lower telescopic bottom end. The bottom section 12 and the movable sections 13 are equipped with locking structures for locking adjacent sections. The relative positions of the movable ladder section 13, the bottom ladder section 12, and the lowest movable ladder section 13; an auxiliary support rod 15 is provided on the lowest step crossbar 11 of the bottom ladder section 12, the auxiliary support rod 15 is perpendicular to the support column 14, the end of the auxiliary support rod 15 away from the step crossbar 11 abuts against the ramp surface, and / or, the side of the auxiliary support rod 15 facing the bottom of the telescopic ladder 1 abuts against the transverse steel bar. In one embodiment, the auxiliary support rod 15 is located at the lower part of the safety ladder. In use, the auxiliary support rod 15 can be abutted against the ramp, or simultaneously abutted against the ramp and the steel bar, and the position of the safety ladder can be adjusted according to the specific situation.
[0033] In this embodiment, the auxiliary support rod 15 and the support component 2 have the same structure, and are also mounted on the step bar 11 via the sliding component 3. The auxiliary support rod 15 ensures that the bottom of the safety ladder can be stably supported on the platform or ground when facing slopes of different angles. Regarding the specific structure of the telescopic ladder 1, it should be noted that single-sided multi-stage telescopic ladders are mature existing technology. The specific telescopic and locking mechanisms are not described in detail here. In the implementation of this application, a commercially available single-sided multi-stage telescopic ladder can be purchased directly, and then the sliding component 3 and the support component 2 can be installed on the step bar 11.
[0034] The plane perpendicular to the length of the telescopic ladder 1 and connected to the bottom surface of the telescopic ladder 1 is the first plane. The sleeve 31, projected onto the first plane, is outside the range of the step bar 11, and the sleeve 31 is fixed to the step bar 11 by a connecting piece. The through groove 34 is located on the side of the sleeve 31 facing away from the step bar 11. This design reduces the interference of the sliding assembly 3 and the support assembly 2 on the telescopic ladder 1's own extension and retraction.
[0035] The support legs 21 of the sliding component 3 are staggered in the width direction of the telescopic ladder 1, and the support legs 21 of the support component 2 are staggered in the width direction of the telescopic ladder 1. This reduces the interference of the design of the sliding component 3 and the support component 2 on the telescopic ladder 1's own extension and retraction, and reduces the space occupied by the safety ladder when it is retracted.
[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
