Abstract
Description
Technical Field
[0001] This utility model relates to the field of ladder technology, specifically to a pedestrian ladder for use on slopes. Background Technology
[0002] In mountainous areas, construction sites, and other sloping terrains, workers face significant challenges to safe passage. Traditional fixed staircases or ladders are ill-suited to complex and varied terrain, especially on steep or irregular slopes. Because ladders are typically fixed to slopes by leaning against them, they are prone to swaying, compromising stability and posing potential safety hazards to workers. Furthermore, the fixed length of traditional ladders prevents flexible adjustments based on terrain requirements, further limiting their applicability and making them unsuitable for diverse work environments. Utility Model Content
[0003] To address the aforementioned problems in the prior art, this utility model provides a pedestrian ladder for slopes, which solves the problems that existing ladders are not securely fixed on slopes and cannot be adjusted in length according to the slope terrain.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A pedestrian ladder for a slope is provided, comprising multiple ladder units that are detachably fixed at both ends. Each ladder unit includes two side plates that are fixedly connected by anti-slip crossbars. At least one ladder unit has a rod for inserting into the slope obliquely arranged on both side plates, and a limit plate is fixed on the rod body of each rod.
[0006] The beneficial effects of this solution are that, through multiple detachable ladder units, it is not only easy to carry, but also allows the length of the entire ladder to be adjusted according to the height of the slope, meeting the needs of different working environments. At the same time, the inclined insertion of the pole into the slope increases the pull-out resistance, preventing insecure fixing and improving safety. Furthermore, the limiting plate ensures a certain distance between the entire ladder and the slope, making it easier for workers to place their feet on the anti-slip crossbars and facilitating climbing.
[0007] Furthermore, the two side plates on adjacent ladder units are connected by connecting plate bolts. The bolt connection facilitates disassembly and fixing.
[0008] Furthermore, the angle between the axis of each insert rod and the length direction of the side plate is 45°. The 45° angle design between the insert rod and the side plate optimizes the mechanical distribution, enhances the shear resistance of the insert rod on the slope, and reduces the risk of slippage caused by external forces.
[0009] Furthermore, each limiting plate is inclinedly welded to the corresponding insert rod, and the angle between the end face of each limiting plate and the axis of the corresponding insert rod is 45°.
[0010] Furthermore, the bottom of both side plates of the bottommost ladder unit are hinged to a fixed plate, which is secured to the ground by fastening pins or bolts. The hinged fixed plate at the bottom allows the bottom of the ladder to adaptively adjust to the undulations of the ground, and the combination of fastening pins or bolts provides double stability, preventing bottom slippage.
[0011] Furthermore, each insertion rod is equipped with a hinged fastener at its connection point with the corresponding side plate for adjusting the rod angle. Each hinged fastener includes a fixing plate and a connecting plate, which are respectively fixed to the side plate and the insertion rod. A connecting post is located in the center of the fixing plate, and the connecting post passes through a through hole in the center of the connecting plate and is threaded to a nut. The hinged fastener adjusts the rod angle via the connecting post and the nut, allowing the insertion rod to dynamically adjust its insertion direction according to the slope gradient, improving terrain adaptability, and facilitating the storage of the insertion rod when not in use.
[0012] Furthermore, each fixed disc and its corresponding connecting disc have meshing end face gears or end face ratchet on their two adjacent end faces. The meshing and locking mechanism of the end face gears / ratchet provides a multi-position angle fixing function, ensuring that the adjusted insertion rod angle is not easily changed by external forces.
[0013] Furthermore, each connecting plate has multiple circumferentially distributed connecting through holes on its end face, and each fixing plate has a pin fixed therethrough for passing through the connecting through holes. The circumferentially distributed connecting through holes, in conjunction with the pin, enable the adjustment of the rod angle in stages, simplifying the operation.
[0014] Furthermore, each connecting post has multiple circumferentially distributed limiting protrusions on its outer wall, and each connecting disc has multiple limiting through slots on its inner wall that respectively mate with the limiting protrusions. The engagement of the limiting protrusions and limiting through slots prevents the connecting disc and the fixed disc from rotating relative to each other, ensuring the stability of the hinged fastener's angle after adjustment and preventing the nuts from loosening and causing failure.
[0015] Furthermore, each anti-slip crossbar has a friction layer on its outer wall. The friction layer (such as a rubber coating or texture) of the anti-slip crossbar increases the friction of the foot contact surface, reducing the risk of slipping and falling in wet / muddy environments.

[0022] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.
[0023] Existing ladders, which are fixed to slopes by direct placement, suffer from swaying. Furthermore, their fixed length prevents flexible adjustment based on terrain requirements. To address these issues, this application provides a pedestrian ladder for slopes, comprising multiple ladder units with detachable ends, and at least one unit equipped with a rod 3 for insertion into the slope. The multiple detachably connected ladder units not only facilitate transport but also allow for length adjustment based on slope height, meeting the needs of different working environments. Simultaneously, the angled insertion of the rod 3 into the slope increases pull-out resistance, preventing insecure fixation and improving safety.
[0024] For details, please refer to Figure 1 Each ladder unit includes two side plates 2 fixedly connected by anti-slip crossbars 1, and each anti-slip crossbar 1 has a friction layer on its outer wall. The friction layer of the anti-slip crossbar 1 increases the friction of the foot contact surface, reducing the risk of slipping and falling in wet / muddy environments.
[0025] The two side plates 2 on two adjacent ladder units are connected by bolts via connecting plates 5. Bolt connections facilitate disassembly and fixation. The bottom of both side plates 2 of the bottom ladder unit are hinged to a fixing plate 6, which is secured to the ground by fastening pins or bolts. The bottom-hinged fixing plate 6 allows the bottom of the ladder to adaptively adjust to ground undulations, and the combination of fastening pins or bolts provides double stability, preventing bottom slippage.
[0026] In this embodiment, at least one ladder unit has two side plates 2 each with an inclined insertion rod 3 for inserting into the ramp, and a limiting plate 4 is fixed to the rod body of each insertion rod 3. The angle between the axis of each insertion rod 3 and the length direction of the side plate 2 is 45°. Each limiting plate 4 is inclinedly welded to the corresponding insertion rod 3, and the angle between the end face of each limiting plate 4 and the axis of the corresponding insertion rod 3 is 45°. The limiting plate 4 allows for a certain distance between the entire ladder and the ramp, making it easier for workers to step on the anti-slip crossbar 1 and climb.
[0027] As another solution in this embodiment, refer to Figure 2 To improve the applicability of the insertion rod 3 to slopes of different gradients and to facilitate the storage of the insertion rod 3, each insertion rod 3 is provided with a hinged fixing member 7 for adjusting the angle of the insertion rod 3 at the connection between the insertion rod 3 and the corresponding side plate 2. Each hinged fixing member 7 includes a fixing plate 71 and a connecting plate 72 respectively fixed on the side plate 2 and the insertion rod 3. A connecting post 711 is provided in the middle of the fixing plate 71, and the connecting post 711 passes through the through hole in the middle of the connecting plate 72 and is threadedly connected to the nut.
[0028] To ensure the stability of the hinge fastener 7 after adjustment and to prevent failure due to loosening of the nut, this embodiment provides the following three connection structures:
[0029] refer to Figure 3 Each fixed plate 71 and its corresponding connecting plate 72 have meshing end face gears or end face ratchet on their two adjacent end faces. The meshing and locking mechanism of the end face gears / ratchet provides a multi-position angle fixing function, ensuring that the adjusted angle of the insertion rod 3 is not easily changed by external force.
[0030] refer to Figure 4 Each connecting plate 72 has multiple circumferentially distributed connecting through holes 721 on its end face, and each fixing plate 71 has a pin 712 fixed on it for passing through the connecting through holes 721. The circumferentially distributed connecting through holes 721, together with the pin 712, enable the insertion rod to be adjusted in three angle increments, simplifying the operation steps.
[0031] refer to Figure 5 Each connecting post 711 has multiple circumferentially distributed limiting protrusions 713 on its outer wall, and each connecting disc 72 has multiple limiting through grooves on its inner wall that respectively cooperate with multiple limiting protrusions 713.
[0032] In summary, the beneficial effects of this plan are as follows:
[0033] The modular design and flexible installation of the ladder units allow for rapid adaptation to different slopes, making it suitable for various incline scenarios on construction sites. It provides workers with a safe and convenient solution for sloping passage. This effectively improves construction efficiency, reduces costs, and ensures safety, demonstrating significant practical value.
[0034] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
