Description

A foldable iron tower ladder Technical Field

[0001] This utility model belongs to the field of tower climbing technology, and in particular relates to a folding tower climbing ladder. Background Technology

[0002] A ladder is a type of ladder specifically designed for vertical movement of people, aiming to provide a safe, stable, and easy-to-use vertical passage and ensure personal safety during ascent and descent. Unlike ordinary ladders, it features a more robust structure, greater load-bearing capacity, and multiple safety features. Ladders are widely used in various applications, including construction of buildings, bridges, overpasses, tunnels, culverts, chimneys, water towers, dams, and large-span scaffolding projects.

[0003] A folding ladder (publication number: CN 205558789U) disclosed includes two ladder square tubes located on the left and right sides respectively, with seven steps between the ladder square tubes. The upper and lower parts of the ladder square tubes are respectively installed at the support lugs connecting the frame using round steel and cotter pins. The steps are formed by bending steel plates, with 5-7 anti-slip openings in the middle. Two round steel sliders are installed at the lower part of the ladder square tubes for assembling the folding and rotating assembly at the lower part of the ladder square tubes. The folding and rotating assembly consists of left and right symmetrical sliding grooves on both sides, and two connecting plates connecting the left and right symmetrical sliding grooves. An opening connecting plate is installed on the upper part of the right sliding groove. When the opening connecting plate is closed, it connects to a closing lock installed on the rear frame diagonal support square tube. The closing lock includes a lock support plate located on the rear frame diagonal support square tube, round steel, and a spring assembly. Using the above technical solution, the ladder is highly safe, easily foldable, and has a certain opening angle, similar to the operator's stair-like movement up and down, and the opening angle is moderate, facilitating climbing.

[0004] However, the components such as the climbing ladder square tube, round steel, and round steel slider in the above application cannot achieve the effect of strengthening and stabilizing the tower climbing ladder. Therefore, we propose a folding tower climbing ladder. Summary of the Invention

[0005] The purpose of this invention is to provide a foldable iron tower ladder, which solves the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a foldable iron tower ladder, including a support leg, a step plate rotatably connected to the support leg, a rotating plate rotatably connected to the step plate, and a strengthening and stabilizing device provided on the support leg.

[0008] Furthermore, the enhanced stabilization device includes a fixed rod rotatably connected to the side of the support leg. A rotating shaft is rotatably connected to the side of the support leg, and a return torsion spring is fixedly connected to the circumferential surface of the rotating shaft. A top plate is fixedly connected to the side of the rotating shaft. A second rotating shaft is rotatably connected to the side of the support leg, and a slot is fixedly connected to the side of the second rotating shaft. A rotating shaft is rotatably connected to the side of the step plate, and a sliding rod is fixedly connected to the side of the rotating shaft. A sliding block is fixedly connected to one end of the fixed rod. This design enhances the stability of the tower ladder, further ensuring the safety of users and reducing the occurrence of accidents.

[0009] Furthermore, one end of the return spring is fixedly connected to the side of the support leg, and a second return torsion spring is fixedly connected to the circumferential surface of the rotating shaft. This design is intended to use the return spring to drive the rotating shaft to return to its original position, while simultaneously folding the slot.

[0010] Furthermore, one end of the second reset torsion spring is fixedly connected to the side of the stepped plate, and the sliding block is slidably connected to the sliding groove in the sliding rod. This design allows the sliding block to slide within the sliding groove of the sliding rod, thereby driving the fixed rod to rotate.

[0011] Furthermore, the initial state of the return torsion spring is relaxed, and a sliding groove is provided inside the sliding rod. This design is to allow the sliding block to move through the sliding groove.

[0012] Furthermore, a telescopic guardrail is provided at the top of the step slab. The telescopic guardrail includes a fixed guard rod, which is fixedly connected to the top of the step slab. A telescopic rod is fixedly connected to the top of the fixed guard rod, and a sliding guard rod is fixedly connected to one end of the telescopic rod. The sliding guard rod is slidably connected to the top of the step slab, and an extension rod is fixedly connected to the side of the sliding rod. One end of the extension rod is fixedly connected to a stop bar. This design aims to provide some protection for the operator and prevent initial falls.

[0013] Furthermore, a force-bearing rod is fixedly connected to one end of the telescopic rod, and a tension spring is fixedly connected to the side of the fixed protective rod. This design is for protection via the telescopic rod.

[0014] Furthermore, the side of the force-bearing rod is located on the displacement trajectory of the impact rod, and one end of the tension spring is fixedly connected to the side of the sliding guard rod. This design is intended to cause the telescopic rod to extend or retract by impacting the force-bearing rod through the rotation of the impact rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model achieves its functionality through the coordinated operation of components such as a fixed rod, a top plate, a sliding rod, and a sliding block. When the operator opens the tower ladder, the support leg is subjected to tension, which drives the fixed rod to rotate clockwise. The clockwise rotation of the fixed rod drives the sliding block to rotate clockwise, and the sliding block rotates clockwise within the sliding groove of the sliding rod. The sliding block drives the sliding rod to rotate counterclockwise under the action of the rotating shaft, and the rotating shaft moves counterclockwise. When one end of the fixed rod touches the slot, it presses down on the slot, and the fixed rod engages with the slot. At the same time, the slot drives the second rotating shaft to rotate counterclockwise. At this time, the slot drives the top plate to rotate counterclockwise, and the counterclockwise rotation of the top plate drives the rotating shaft to rotate counterclockwise. At this time, the reset torsion spring is in a taut state, thereby achieving a strengthening and stabilizing effect on the tower ladder and improving its safety.

[0017] 2. This utility model achieves its purpose through the cooperation of components such as a fixed guardrail, a telescopic guardrail, and a sliding guardrail. When the sliding guardrail moves counterclockwise, it drives the extension guardrail to rotate counterclockwise. The counterclockwise rotation of the extension guardrail drives the impact guardrail to rotate counterclockwise. The counterclockwise rotation of the impact guardrail strikes the force-bearing guardrail. The force-bearing guardrail, subjected to the impact force, drives the telescopic guardrail to move horizontally. The horizontal movement of the telescopic guardrail drives the sliding guardrail to move horizontally, thus forming a guardrail and achieving the protection of the operator.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please refer to Figures 1-4. This utility model is a foldable iron tower ladder, including a support leg 1, a step plate 2 rotatably connected to the support leg 1, a rotating plate 3 rotatably connected to the step plate 2, and a strengthening and stabilizing device 4 provided on the support leg 1.

[0029] The stabilizing device 4 includes a fixed rod 41, which is rotatably connected to the side of the support leg 1. A rotating shaft 42 is rotatably connected to the side of the support leg 1. A return torsion spring 43 is fixedly connected to the circumference of the rotating shaft 42. A top plate 44 is fixedly connected to the side of the rotating shaft 42. A second rotating shaft 45 is rotatably connected to the side of the support leg 1. A slot 46 is fixedly connected to the side of the second rotating shaft 45. A rotating shaft 47 is rotatably connected to the side of the step plate 2. A sliding rod 48 is fixedly connected to the side of the rotating shaft 47. A sliding block 411 is fixedly connected to one end of the fixed rod 41. This design enhances the stability of the tower ladder, further ensuring the safety of users and reducing the occurrence of accidents.

[0030] One end of the return spring 43 is fixedly connected to the side of the support leg 1, and a second return torsion spring 49 is fixedly connected to the circumferential surface of the rotating shaft 47. This design is intended to drive the rotating shaft 42 to return to its original position via the return spring 43, while simultaneously folding the slot 46.

[0031] One end of the second reset torsion spring 49 is fixedly connected to the side of the step plate 2, and the sliding block 411 is slidably connected to the sliding groove 410 in the sliding rod 48. This design allows the sliding block 411 to slide in the sliding groove 410 inside the sliding rod 48, thereby driving the fixed rod 41 to rotate.

[0032] The initial state of the reset torsion spring 43 is relaxed, and the sliding rod 48 has a sliding groove 410 inside. This design is to allow the sliding block 411 to move through the sliding groove 410.

[0033] A telescopic guardrail 5 is installed at the top of the step slab 2. The telescopic guardrail 5 includes a fixed guardrail 51, which is fixedly connected to the top of the step slab 2. A telescopic rod 52 is fixedly connected to the top of the fixed guardrail 51. A sliding guardrail 53 is fixedly connected to one end of the telescopic rod 52 and is slidably connected to the top of the step slab 2. An extension rod 54 is fixedly connected to the side of the sliding rod 54, and a stop bar 55 is fixedly connected to one end of the extension rod 54. This design is intended to provide some protection for the operator and prevent falls.

[0034] One end of the telescopic rod 52 is fixedly connected to a force-bearing rod 56, and a tension spring 57 is fixedly connected to the side of the fixed protective rod 51. This design is for protection via the telescopic rod 52.

[0035] The side of the force-bearing rod 56 is located on the displacement trajectory of the impact rod 55, and one end of the tension spring 57 is fixedly connected to the side of the sliding guard rod 53. This design is intended to cause the telescopic rod 52 to extend or retract by impacting the force-bearing rod 56 through the rotation of the impact rod 55.

[0036] A specific application of this embodiment is as follows: When the operator opens the tower ladder, the support leg 1 is subjected to tension, which drives the fixed rod 41 to rotate clockwise. The clockwise rotation of the fixed rod 41 drives the sliding block 411 to rotate clockwise. The sliding block 411 rotates clockwise in the sliding groove 410 inside the sliding rod 48. The sliding block 411 drives the sliding rod 48 to rotate counterclockwise under the action of the rotating shaft 47. The rotating shaft 47 moves counterclockwise. When one end of the fixed rod 41 touches the slot 46, the slot 46 is pressed down, and the fixed rod 41 engages with the slot 46. At the same time, the slot 46 drives the second rotating shaft 45 to rotate counterclockwise. At this time, the slot 46 drives the top plate 44 to rotate counterclockwise. The counterclockwise rotation of the top plate 44 drives the rotating shaft 42 to rotate counterclockwise. At this time, the reset torsion spring 43 is in a taut state. When the operator retracts the tower ladder, the support leg 1 is pushed, which drives the fixed rod 41 to rotate counterclockwise. The counterclockwise rotation of the fixed rod 41 drives the sliding block 411 to rotate counterclockwise within the sliding groove 410. The counterclockwise rotation of the sliding block 411 drives the sliding rod 48 to rotate clockwise. The clockwise rotation of the sliding rod 48 drives the rotating shaft 47 to rotate clockwise and reset. At the same time, the second reset torsion spring 49 applies a reset torque to make the rotating shaft 47 rotate more smoothly. When the fixed rod 41 leaves the slot 46, the reset torque of the reset torsion spring 43 drives the rotating shaft 42 to rotate counterclockwise. The counterclockwise rotation of the rotating shaft 42 drives the top plate 44 to rotate counterclockwise, folding the slot 46 back to its original position, thus collecting the tower ladder. When the strengthening and stabilizing device 4 is opened, it achieves the effect of strengthening the stability of the tower ladder and improving its safety.

[0037] When the sliding rod 48 moves counterclockwise, it drives the extension rod 54 to rotate counterclockwise. The counterclockwise rotation of the extension rod 54 drives the impact rod 55 to rotate counterclockwise. The impact rod 55 strikes the force-bearing rod 56, and the force-bearing rod 56, under the impact force, drives the telescopic rod 52 to move horizontally. The horizontal movement of the telescopic rod 52 drives the sliding guard rod 53 to move horizontally, thus forming a guardrail. When the sliding rod 48 rotates clockwise, it drives the extension rod 54 to rotate clockwise, and the clockwise rotation of the extension rod 54 drives the impact rod 55 to rotate clockwise. The force-bearing rod 56 loses its impact force. At this time, the tension of the tension spring 57 drives the sliding guard rod 53 to move horizontally and reset. The horizontal movement of the sliding guard rod 53 drives the telescopic rod 52 to retract, completing the collection function of the equipment. When the telescopic guardrail is deployed, it provides protection for the operators.
