This utility model discloses a climbing ladder for building construction, whose structure includes a first handrail, a clamping plate, a first support block, an anti-slip pedal, a second support block, and a second handrail. The lower surface of the clamping plate is respectively welded with a first support block and a second support block. The left and right sides of the anti-slip pedal are respectively connected to the first support block and the second support block. The surface of the first support block is connected to the first handrail, and the second handrail is connected to the second support block. This utility model is provided with an anti-slip pedal, realizing that the climbing ladder for building construction can effectively prevent the user from accidentally slipping during climbing, thereby improving the safety performance of the equipment during use. It is convenient to use and has strong practicability, solving the problem that the existing climbing ladder for building construction has no effective measure to prevent the user from accidentally slipping during climbing, resulting in a decline in the safety performance of the equipment during use, inconvenience in use, and poor practicability.

[0004] In daily work, it is found that when the above-mentioned climbing ladder is in use, it is usually placed on the building directly, resulting in easy tilting and shaking during use, and an unstable phenomenon, especially in the case of strong winds, which may cause safety accidents when construction workers climb through the climbing ladder, and poor safety. Furthermore, it leads to poor stability when the existing climbing ladder is placed, resulting in an unsafe problem. Content of the Utility Model

[0005] The purpose of the present utility model is to solve the drawback of poor stability and insecurity when the existing climbing ladder is placed, and to propose a climbing ladder structure for building construction.

[0006] To achieve the above object, the utility model adopts the following technical scheme: A climbing ladder structure for building construction, including a climbing ladder body and a stabilizing device. A plurality of treads are arranged on the surface of the climbing ladder body, and two handrails are arranged on the surface of the climbing ladder body. The stabilizing device is arranged on the surface of the climbing ladder body. The stabilizing device includes a hollow sleeve. The number of the hollow sleeves is two, and the two hollow sleeves are respectively fixedly connected to the two side surfaces of the climbing ladder body. A clamping plate is slidably connected to the inner walls of the two hollow sleeves. Three anti-slip components are arranged on the surface of the clamping plate. A transmission screw is rotatably connected to the inner wall of the hollow sleeve. The transmission screw is threadedly connected to the inner wall of the clamping plate. Through the above components, when the climbing ladder body is placed on a building, the transmission screw can be rotated, and the transmission screw can drive the clamping plate to slide in the hollow sleeve, so that the clamping plate cooperates with the anti-slip components and the climbing ladder body to clamp the building, improving the overall stability effect when the climbing ladder body is used and making the climbing ladder body safer.

[0007] Preferably, the anti-slip components include sliding rods. The number of the sliding rods is two, and the two sliding rods are slidably connected to the inner wall of the clamping plate. The upper ends of the two sliding rods are fixedly connected with an anti-slip plate. The anti-slip plate is made of rubber material. Through the above components, when the clamping plate moves, it can drive the anti-slip plate to move, and the rubber anti-slip plate can fit with the building, thus playing an anti-slip role.

[0008] Preferably, two groups of anti-slip teeth are fixedly connected to the surface of the anti-slip plate. The two groups of anti-slip teeth are inclined to both sides. Through the above components, the two groups of inclined anti-slip teeth can increase the friction force and make the equipment more stable in use.

[0009] Preferably, a spring is sleeved on the surface of the sliding rod. The two ends of the spring are respectively fixedly connected to the surfaces of the sliding rod and the clamping plate. Through the above components, when the clamping plate moves, the anti-slip plate and the anti-slip teeth come into contact with the building in advance and are squeezed. The spring deforms under force. When the clamping plate moves to a certain position, the elastic force of the spring can make the overall clamping of the equipment more precise.

[0010] Preferably, a transmission wheel is fixedly connected to the lower end of the transmission screw. A transmission belt is installed on the surfaces of the two transmission wheels. Through the above components, when one group of transmission screws rotates, the transmission wheel cooperates with the transmission belt to drive the other group of transmission screws to rotate.

[0011] Preferably, a maintenance device is arranged between the tread and the climbing ladder body. The maintenance device includes insertion blocks. The number of the insertion blocks is two. Slots are formed on the surface of the climbing ladder body. The insertion blocks are inserted into the inner walls of the slots. Through the above components, the insertion blocks on the surface of the tread and the slots on the surface of the climbing ladder body can be used to quickly install the tread, thus facilitating subsequent maintenance and replacement of the tread.

[0012] Preferably, positioning screws are threadedly connected to the inner walls on both sides of the ladder body. The positioning screws are inserted into the inner walls of the insertion blocks. A limiting ring is fixedly connected to the surface of the positioning screws. Limiting sleeves are respectively fixedly connected to both sides of the ladder body. The limiting ring is arranged in the limiting sleeve. Through the above components, the insertion blocks can be stably restricted in the slots on the surface of the ladder body by the positioning screws. The limiting ring and the limiting sleeve can limit the moving range of the positioning screws.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Please refer to Figures 1-5 Figures 1-5

[0024] The following specifically describes the specific settings and functions of its stabilizing device 4 and maintenance device 5.

[0025] Specifically, the stabilizing device 4 includes hollow sleeves 41. There are two hollow sleeves 41, and the two hollow sleeves 41 are respectively fixedly connected to the two side surfaces of the ladder body 1. A clamping plate 42 is slidably connected to the inner walls of the two hollow sleeves 41. Three groups of anti-slip components 43 are arranged on the surface of the clamping plate 42. A transmission screw 46 is rotatably connected to the inner wall of the hollow sleeve 41, and the transmission screw 46 is threadedly connected to the inner wall of the clamping plate 42.

[0026] In this embodiment: After the ladder body 1 is placed on the building, the transmission screw 46 can be rotated. The transmission screw 46 can drive the clamping plate 42 to slide in the hollow sleeve 41, so that the clamping plate 42 cooperates with the anti-slip components 43 and the ladder body 1 to clamp the building, improving the overall stability effect when the ladder body 1 is used and making the ladder body 1 safer.

[0027] Specifically, the anti-slip component 43 includes sliding rods 431. There are two sliding rods 431, and the two sliding rods 431 are slidably connected to the inner wall of the clamping plate 42. The upper ends of the two sliding rods 431 are fixedly connected with an anti-slip plate 432. The anti-slip plate 432 is made of rubber material. When the clamping plate 42 moves, it can drive the anti-slip plate 432 to move. The rubber anti-slip plate 432 can fit with the building, thus playing an anti-slip role.

[0028] Specifically, two groups of anti-slip teeth 433 are fixedly connected to the surface of the anti-slip plate 432, and the two groups of anti-slip teeth 433 are inclined to both sides.

[0029] In this embodiment: The two groups of inclined anti-slip teeth 433 can increase the friction force and make the equipment more stable during use.

[0030] Specifically, a spring 434 is sleeved on the surface of the sliding rod 431. The two ends of the spring 434 are respectively fixedly connected to the surface of the sliding rod 431 and the clamping plate 42. When the clamping plate 42 moves, the anti-slip plate 432 and the anti-slip teeth 433 come into contact with the building in advance and are squeezed. The spring 434 deforms under force. When the clamping plate 42 moves to a certain position, the elastic force of the spring 434 can make the overall clamping of the equipment more precise.

[0031] Specifically, a transmission wheel 44 is fixedly connected to the lower end of the transmission screw 46, and a transmission belt 45 is mounted on the surfaces of the two transmission wheels 44.

[0032] In this embodiment: When a set of transmission screws 46 rotates, the transmission wheel 44 cooperates with the transmission belt 45 to drive the other set of transmission screws 46 to rotate.

[0033] Specifically, a maintenance device 5 is provided between the pedal 2 and the ladder body 1. The maintenance device 5 includes insertion blocks 54. The number of insertion blocks 54 is two. Slots 55 are formed on the surface of the ladder body 1. The insertion blocks 54 are inserted into the inner walls of the slots 55. The insertion blocks 54 on the surface of the pedal 2 and the slots 55 on the surface of the ladder body 1 can be used to quickly install the pedal 2, facilitating subsequent maintenance and replacement of the pedal 2.

[0034] Specifically, positioning screws 51 are threadedly connected to the inner walls on both sides of the ladder body 1. The positioning screws 51 are inserted into the inner walls of the insertion blocks 54. A limit ring 53 is fixedly connected to the surface of the positioning screw 51. Limit sleeves 52 are fixedly connected to both sides of the ladder body 1 respectively. The limit ring 53 is arranged in the limit sleeve 52.

[0035] In this embodiment: Through the positioning screw 51, the insertion block 54 can be stably restricted in the slot 55 on the surface of the ladder body 1. The limit ring 53 cooperates with the limit sleeve 52 to limit the moving range of the positioning screw 51.

[0036] Working principle: When in use, the ladder body 1 can be placed on the protrusion of the building. Then, the transmission screw 46 is rotated. The transmission screw 46 cooperates with the belt and the transmission wheel 44 to drive the other set of transmission screws 46 to rotate. When the two sets of transmission screws 46 rotate, they can drive the clamping plate 42 to move in the hollow sleeve 41. After the clamping plate 42 moves to a certain position, the anti-slip plate 432 and the anti-slip teeth 433 contact the lower surface of the building protrusion. The clamping plate 42 continues to move, and the spring 434 deforms under force. When it moves to a certain position, the clamping plate 42 cooperates with the anti-slip plate 432 and the left and right inclined anti-slip teeth 433 to fit with the lower surface of the building protrusion, thereby realizing a clamping effect in cooperation with the ladder body 1 and improving the stability effect when the ladder body 1 is placed. When it is necessary to disassemble, maintain or replace the pedal 2, the positioning screw 51 is rotated. After the positioning screw 51 moves to a certain position, the limit ring 53 abuts against the inner wall of the limit sleeve 52. At this time, the positioning screw 51 moves out of the inner wall of the insertion block 54. Then, the pedal 2 is pulled to the side away from the ladder body 1, and the insertion block 54 is pulled out of the slot 55 on the surface of the ladder body 1, and then maintenance and replacement can be carried out.
