Description

Technical Field

[0001] This utility model relates to the technical field of steel structure construction tools, specifically a fixed structure for a vertical climbing ladder used in steel structure installation. Background Technology

[0002] Steel structures are structural systems composed of steel materials such as steel plates, structural steel, and steel pipes, connected by welding, bolting, or riveting. They are characterized by high strength, light weight, fast construction speed, and good seismic performance. During the installation of steel structures, workers need to climb to different heights for construction, so ladders are essential safety equipment. Fixed structures can improve the stability of the ladders and reduce the risk of safety accidents.

[0003] Chinese utility model patent CN221682863U discloses a stable and fixed steel structure construction ladder, including a ladder body, a support mechanism, and a stabilizing mechanism. Fixed sleeves are fixedly connected to both sides of the bottom end of the ladder body. The fixed sleeves are fitted onto the upper ends of another ladder body. A support mechanism is provided at the rear end of the fixed sleeves. The support mechanism includes a support frame, a reinforcing rod, a first connecting gasket, and a sliding groove. The support frame is fixedly connected to the middle of the rear end of the fixed sleeve. This utility model, through the design and coordination of the support mechanism and the stabilizing mechanism, maintains a certain distance between the ladder body and the steel structure column, achieving both fixation and convenient use of the ladder body. The springs and connecting rods on the stabilizing mechanism allow the clamps to be fixed to both sides of the steel structure column, thereby improving the stability of the steel structure column and the ladder body. It also allows for fine-tuning of the clamps, preventing inconvenience in installing the ladder body onto the steel structure column.

[0004] To secure the ladder sections, the aforementioned stable steel construction ladder is equipped with fixing sleeves, through holes, threaded holes, and bolts. However, this stable steel construction ladder lacks the function of limiting the bolts. During steel structure construction, the ladder is subjected to external forces such as vertical impact forces and horizontal swaying forces generated when workers climb it. Without limiting the bolts, the bolts may gradually loosen under the repeated action of these external forces, reducing the stability of the connection between the two ladder sections. This could lead to local deformation or even collapse of the ladder, posing a significant risk of falls to workers climbing it and seriously threatening their lives. Utility Model Content

[0005] This utility model provides a fixing structure for a vertical climbing ladder for steel structure installation, in order to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixed structure for a vertical climbing ladder for steel structure installation, comprising a fixed rod, a crossbar fixedly disposed between opposite sides of the fixed rod, a fixed sleeve fixedly disposed at the bottom of the fixed rod, threaded holes on three sides of the fixed sleeve, and a threaded rod movably disposed within the threaded holes, a hexagonal nut fixedly disposed at one end of the threaded rod, a protective shell movably disposed outside the hexagonal nut, a hexagonal groove adapted to the hexagonal nut being provided on the side of the protective shell near the fixed sleeve, the protective shell and the hexagonal nut being connected by a movable insertion, an L-shaped rod fixedly disposed on the outer wall of the protective shell, a movable plate fixedly disposed at one end of the L-shaped rod, a rotating seat movably disposed outside the movable plate, the rotating seat and the movable plate being connected by a sliding connection, the rotating seat and the fixed sleeve being connected by a rotational connection, a return spring fixedly disposed on the side of the movable plate near the L-shaped rod, the return spring and the L-shaped rod being connected by a sleeve, and one end of the return spring being fixedly connected to the inner wall of the rotating seat.

[0007] Furthermore, an anti-slip pad is fixedly installed on the top of the crossbar.

[0008] Furthermore, the anti-slip mat is made of rubber.

[0009] Furthermore, a support frame is fixedly provided in the middle of the back of the fixing sleeve, and connecting gaskets are fixedly provided on both sides of the top and bottom of the support frame.

[0010] Furthermore, a reinforcing rod is fixedly provided on the front side of the support frame.

[0011] Furthermore, the top of the fixed rod is provided with slots on three sides that are compatible with the threaded rod, and the connection between the slots and the threaded rod is a movable insertion.

[0012] Compared with the prior art, this utility model provides a fixing structure for a vertical climbing ladder for steel structure installation, which has the following beneficial effects:

[0013] 1. The fixed structure for the vertical climbing ladder used in the steel structure installation involves a protective shell, an L-shaped rod, a movable plate, a rotating seat, and a return spring. After two ladders are fixedly connected, pulling the L-shaped rod away from the fixed sleeve causes the protective shell and movable plate to move. The return spring deforms, and when the bottom of the protective shell is higher than the top of the hexagonal nut, rotating the L-shaped rod causes the movable plate to rotate, and the rotating seat rotates within the fixed sleeve until the protective shell and the hexagonal nut are aligned. Releasing the L-shaped rod allows the movable plate to move under the elastic force of the return spring, causing the hexagonal nut to insert into the hexagonal groove of the protective shell. This limits the position of the hexagonal nut, preventing displacement of the threaded rod under stress, thus ensuring the stability of the connection between the ladders and preventing local deformation or even collapse of the ladders due to loose threaded rods, effectively protecting the lives of construction personnel.

[0018] 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.

[0019] Please see Figure 1-3This utility model discloses a fixing structure for a vertical climbing ladder for steel structure installation, including a fixing rod 1. A crossbar 201 is fixedly arranged between opposite sides of the fixing rod 1. A fixing sleeve 203 is fixedly arranged at the bottom of the fixing rod 1. Threaded holes are opened on three sides of the fixing sleeve 203, and a threaded rod 301 is movably arranged in the threaded holes. A hexagonal nut 302 is fixedly arranged at one end of the threaded rod 301. A protective shell 303 is movably arranged on the outside of the hexagonal nut 302. A hexagonal groove adapted to the hexagonal nut 302 is opened on the side of the protective shell 303 near the fixing sleeve 203. The protective shell 303 and the hexagonal nut 302 are connected. The connection relationship of 02 is a movable plug-in connection. An L-shaped rod 304 is fixedly installed on the outer wall of the protective shell 303. A movable plate 305 is fixedly installed at one end of the L-shaped rod 304. A rotating seat 306 is movably installed on the outside of the movable plate 305. The connection relationship between the rotating seat 306 and the movable plate 305 is a sliding connection. The connection relationship between the rotating seat 306 and the fixed sleeve 203 is a rotating connection. A return spring 307 is fixedly installed on the side of the movable plate 305 near the L-shaped rod 304. The connection relationship between the return spring 307 and the L-shaped rod 304 is a sleeve connection. One end of the return spring 307 is fixedly connected to the inner wall of the rotating seat 306.

[0020] Specifically, an anti-slip pad 202 is fixedly provided on the top of the crossbar 201.

[0021] In this implementation plan, by setting up a crossbar 201 and an anti-slip mat 202, the anti-slip mat 202 can increase the friction on the surface of the crossbar 201, and can effectively prevent construction workers from slipping when climbing even when there are water stains, oil stains or dust, thus reducing the probability of safety accidents.

[0022] Specifically, the anti-slip mat 202 is made of rubber.

[0023] In this implementation plan, by setting up anti-slip mat 202, the rubber material is wear-resistant and can withstand frequent stepping and friction by construction workers, so that the rubber anti-slip mat 202 can maintain good anti-slip and cushioning performance for a long time, reducing the frequency of replacing the anti-slip mat 202 and reducing the cost of use.

[0024] Specifically, a support frame 401 is fixedly installed in the middle of the back of the fixed sleeve 203, and connecting gaskets 402 are fixedly installed on both sides of the top and bottom of the support frame 401.

[0025] In this implementation scheme, by setting up a support frame 401 and a connecting gasket 402, and passing cement nails through the connecting gasket 402, a stable connection can be made between the support frame 401 and the steel structure, thus achieving the purpose of rapid installation.

[0026] Specifically, a reinforcing rod 403 is fixedly provided on the front side of the support frame 401.

[0027] In this embodiment, by setting a reinforcing rod 403, the strength of the support frame 401 can be improved, further enhancing the stability of the equipment.

[0028] Specifically, the top three sides of the fixed rod 1 are provided with slots 404 that are adapted to the threaded rod 301, and the connection between the slots 404 and the threaded rod 301 is a movable insertion.

[0029] In this implementation scheme, by setting the threaded rod 301 and the slot 404, the movable plug-in method eliminates the need for complicated connection operations. Construction personnel only need to insert the threaded rod 301 into the slot 404 to complete the fixation, which greatly shortens the installation time and improves construction efficiency.

[0030] In use, first select an appropriate number of ladders according to the height of the steel structure. Then, place one ladder on the upper part of the steel structure surface and pre-fix the ladder to the steel structure using a sturdy structure. Finally, fix the ladder by passing cement nails through the connecting washer 402. Similarly, pre-fix the other ladder to the steel structure and then push the other ladder upward. When the top of its fixing rod 1 moves into the fixing sleeve 203 of the upper ladder, pre-fix it again. After pre-fixing, turn the hexagonal nut 302, and the threaded rod 301 will rotate until one end of the threaded rod 301 is inserted into the slot 404, thus fixing the ladders together. After fixing, pull the L-shaped rod 304 away from the fixing sleeve 203. The protective shell 303 and the moving plate 305 will move accordingly, and the return spring 307 will deform. When the bottom of the protective shell 303 is higher than the top of the hexagonal nut 302, rotate the L-shaped rod 304. The rod 304 drives the moving plate 305 to rotate, and the rotating seat 306 rotates within the fixed sleeve 203 until the protective shell 303 and the hexagonal nut 302 are aligned. The L-shaped rod 304 is then released. Under the elastic force of the return spring 307, the moving plate 305 drives the L-shaped rod 304 and the protective shell 303 to move, thereby allowing the hexagonal nut 302 to be inserted into the hexagonal groove of the protective shell 303. This achieves the purpose of limiting the hexagonal nut 302, making it difficult for the threaded rod 301 to shift under force, thus ensuring the stability of the connection between the ladders. During construction, workers can climb up using the crossbar 201 for easy operation. The anti-slip mat 202 significantly increases the friction between the workers' shoes and the crossbar 201, preventing falls due to slipping. The stabilizing structure has been described in detail in a stable and fixed steel structure construction ladder published in CN221682863U, and will not be repeated here.

[0031] In summary, the fixing structure of this vertical climbing ladder for steel structure installation, by setting up a protective shell 303, an L-shaped rod 304, a movable plate 305, a rotating seat 306, and a return spring 307, after fixing two ladders together, pulling the L-shaped rod 304 away from the fixing sleeve 203 causes the protective shell 303 and the movable plate 305 to move accordingly. The return spring 307 deforms, and when the bottom of the protective shell 303 is higher than the top of the hexagonal nut 302, rotating the L-shaped rod 304 causes the movable plate 305 to rotate, thus the rotating seat 306 rotates at the fixing sleeve 203. Rotate the L-shaped rod 304 until the protective shell 303 and the hexagonal nut 302 are aligned. Loosen the L-shaped rod 304. Under the elastic force of the return spring 307, the moving plate 305 moves the L-shaped rod 304 and the protective shell 303, thereby allowing the hexagonal nut 302 to be inserted into the hexagonal groove of the protective shell 303. This achieves the purpose of limiting the hexagonal nut 302, making it difficult for the threaded rod 301 to shift under force. This ensures the stability of the connection between the ladders and prevents the ladders from deforming or even collapsing due to the loosening of the threaded rod 301, thus effectively protecting the lives of construction personnel.
