Description

Technical Field

[0001] This utility model relates to the field of folding ladder technology, specifically to a wall-mounted suspended folding ladder. Background Technology

[0002] In large-span buildings such as industrial plants and warehouses, cantilever walls are widely used as a typical structural form. Their characteristic feature is that the top of the wall extends horizontally outward through reinforced concrete beams or slabs, forming an inverted L-shaped cantilever structure when viewed from the side. This type of wall design effectively solves the needs for equipment installation, pipeline laying, and the fixing of auxiliary facilities. During daily production and maintenance, workers need to climb to the top of the cantilever wall to perform equipment inspection, pipeline maintenance, or facility adjustment work.

[0003] Currently, climbing operations mainly rely on two solutions: movable ladders and fixed inclined ladders. However, both have significant drawbacks: 1. Movable ladders are usually made of lightweight aluminum alloy or steel. Although easy to move, they are often temporarily borrowed by other workers and not returned to their original positions, resulting in a lack of ladders when needed urgently. Especially in factories with multiple shifts working simultaneously, the arbitrary movement of ladders leads to maintenance delays and takes up time for equipment troubleshooting, directly affecting production efficiency and operational safety. 2. To solve the management problem of movable ladders, some places use fixed inclined ladders that are welded or bolted. These inclined ladders extend outward at an angle of 15°-45°, not only occupying the horizontal space around the cantilevered wall and affecting the passage of forklifts, transport vehicles, and other equipment, but also encroaching on the goods stacking area in the warehouse area. Moreover, the protruding ladders also pose safety hazards. It is very unsafe for others to accidentally bump into the ladder or forklifts to collide with it. Utility Model Content

[0004] The purpose of this utility model is to provide a wall-mounted folding ladder that can be installed in a fixed position to prevent unauthorized relocation and the inability to find the ladder in an emergency. It can also be folded and placed against the wall in a fixed position to reduce space occupation and avoid the problem of traditional fixed inclined ladders occupying passageways and cargo areas.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a wall-mounted folding ladder, comprising:

[0006] A pair of parallel L-shaped brackets, each bracket including a horizontally extending wall connection section and a vertically extending extension connection section, one end of the wall connection section being connected to the cantilever wall, and one end of the extension connection section being connected to the cantilever wall extension.

[0007] A limiting groove is provided on the wall connection section;

[0008] A folding ladder includes a main ladder section and a secondary ladder section connected by hinges. The load-bearing crossbar at the top of the main ladder section is slidably suspended on the wall connection section and can slide along it into a limiting groove.

[0009] A further improvement of this utility model is that an axially penetrating alignment groove is provided on the mating surface of the main ladder section and the auxiliary ladder section. A reinforcing shaft is slidably connected in the alignment groove. The alignment groove includes a first groove in the main ladder section and a second groove in the auxiliary ladder section. The length of the reinforcing shaft is greater than the length of the second groove, and it can be slid into the first groove by an adjustment component to allow the auxiliary ladder section to fold, or inserted into the second groove to achieve a rigid connection of the ladder body.

[0010] A further improvement of this utility model is that the adjustment component includes a control port disposed on the main ladder section and communicating with the first slide groove, and an operating handle disposed on the reinforcing shaft and extending out of the control port. The control port includes a vertical slide and a transverse locking groove communicating with the upper end of the vertical slide. When the operating handle rotates with the reinforcing shaft handle and enters the transverse locking groove, the reinforcing shaft is completely retracted into the first slide groove.

[0011] A further improvement of this utility model is that the limiting groove is a U-shaped snap-fit ​​part formed by bending one end of the wall connection section.

[0012] A further improvement of this utility model is that the wall connecting section, the limiting groove, and the extension connecting section are integrally formed.

[0013] A further improvement of this utility model is that the wall connecting section is provided with a wall-mounted limiting protrusion, and the distance between the wall-mounted limiting protrusion and the cantilever wall is adapted to the thickness of the folded ladder after folding.

[0014] A further improvement of this utility model is that at least one reinforcing connecting rod is provided between the two L-shaped brackets.

[0015] A further improvement of this utility model is that the upper end height of the extension connecting section is adapted to the top surface height of the cantilever wall extension, and a first mounting plate is provided thereon, the first mounting plate being fixed to the upper end of the cantilever wall extension by bolts.

[0016] A further improvement of this utility model is that a second mounting plate is vertically provided at one end of the wall connection section, and the second mounting plate is fixed to the cantilever wall by bolts.

[0017] The beneficial effects of this utility model are as follows:

[0018] This utility model uses an L-shaped bracket and a folding ladder to be installed in a fixed position, ensuring that the ladder cannot be moved at will, preventing it from being misappropriated or lost, and preventing problems such as unauthorized misappropriation or not being able to find the ladder in an emergency.

[0019] This utility model adopts a folding ladder, with the main ladder section and the auxiliary ladder section hinged together. The distance between the folding ladder and the wall is limited by the wall-mounted limiting protrusion, which prevents the ladder from shaking or protruding after being folded. After folding, it fits tightly against the wall, greatly reducing the space occupied and solving the problem of traditional fixed inclined ladders occupying passageways.

[0020] In this invention, the reinforcing shaft is slidably connected in the first groove of the main ladder section and the second groove of the auxiliary ladder section. When unfolded, it is inserted into the second groove to form a rigid connection and improve the overall strength of the ladder body. When folded, the reinforcing shaft is retracted into the first groove to avoid the protruding part from affecting storage. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1: Combination Figures 1-4 It is known that a wall-mounted folding ladder includes:

[0028] A pair of parallel L-shaped brackets 1, each bracket including a horizontally extending wall connection section 2 and a vertically extending extension connection section 3, one end of the wall connection section 2 being connected to the cantilever wall, and one end of the extension connection section 3 being connected to the extension of the cantilever wall.

[0029] Limiting groove 4 is provided on wall connection section 2;

[0030] The folding ladder includes a main ladder section 5 and a secondary ladder section 6 connected by hinges. The load-bearing crossbar at the top of the main ladder section is slidably suspended on the wall connection section 2 and can slide along it into the limiting groove 4.

[0031] When the folding ladder is in its stowed state, the secondary ladder section 6 rotates around the hinge and folds down until it is parallel to the main ladder section 5. At this point, the bottom of the folding ladder is suspended from the ground for storage. Preferably, both the main ladder section and the secondary ladder section have folding fixing holes that connect when folded. The two folding fixing holes are secured by pins passing through the folding fixing holes between the main and secondary ladder sections after folding, preventing accidental unfolding. Alternatively, it can be secured by external straps or nylon ropes.

[0032] When the folding ladder is unfolded, the secondary ladder section 6 unfolds and is aligned in a straight line with the main ladder section 5. The total length of the folding ladder is greater than the height of the wall connection section. At this time, the folding ladder is rotated in the limiting groove 4 to keep it tilted. One end of the ladder is in contact with the ground, and the other end is in contact with the groove wall of the limiting groove 4, which can achieve tilting and unfolding for easy climbing.

[0033] The mating surfaces of the main stair section 5 and the secondary stair section 6 are provided with axially penetrating alignment grooves. A reinforcing shaft 7 is slidably connected in the alignment grooves. The alignment grooves include a first groove 8 provided in the main stair section 5 and a second groove 9 provided in the secondary stair section 6. The length of the reinforcing shaft 7 is greater than the length of the second groove 9, and it can be slid into the first groove 8 through an adjustment component to allow the secondary stair section 6 to fold, or inserted into the second groove 9 to achieve a rigid connection of the ladder body.

[0034] The adjustment assembly includes a control port 10 on the main ladder section 5 that communicates with the first slide groove 8 and an operating handle 11 on the reinforcing shaft 7 that extends out of the control port 10. The control port 10 includes a vertical slide and a transverse locking groove that communicates with the upper end of the vertical slide. When the operating handle 11 rotates with the handle of the reinforcing shaft 7 and enters the transverse locking groove, the reinforcing shaft 7 is completely retracted into the first slide groove 8.

[0035] The limiting groove 4 is a U-shaped locking part formed by bending one end of the wall connecting section 2. Preferably, the height difference between the bottom of the limiting groove 4 and the upper end of the wall connecting section is greater than 10cm, which facilitates the adjustment of the angle of the unfolded folding ladder.

[0036] The wall connection section 2, the limiting groove and the extension section 3 are integrally formed.

[0037] The wall connection section 2 is provided with a wall-mounted limiting protrusion 12, and the distance between the wall-mounted limiting protrusion 12 and the cantilever wall is adapted to the thickness of the folded ladder after folding.

[0038] At least one reinforcing connecting rod 13 is provided between the two L-shaped brackets 1. Preferably, the reinforcing connecting rod 13 is located between the two wall connecting sections 2.

[0039] The upper end of the extension connecting section 3 is adapted to the top surface height of the cantilever wall extension, and a first mounting plate 14 is provided on it. The first mounting plate 14 is fixed to the upper end of the cantilever wall extension by bolts.

[0040] A second mounting plate 15 is vertically provided at one end of the wall connection section 2, and the second mounting plate 15 is fixed to the cantilever wall by bolts.

[0041] The working principle of the wall-mounted folding ladder provided by the utility model is as follows: When in use, first drag the folding ladder to slide it along the wall connecting section 2 into the limiting groove 4, ensuring that it is fully engaged. Then, pull the folded secondary ladder section 6 outward so that it unfolds around the hinge and is aligned in a straight line with the main ladder section 5. Control the operating handle 11 to insert the reinforcing shaft 7 into the second sliding groove 9 to form a rigid connection. Adjust the tilt angle of the unfolded folding ladder so that one end of the folding ladder abuts the ground and the other end abuts the groove wall of the limiting groove 4. After the connection is stable, you can climb. After the operation is completed, control the operating handle 11 again to retract the reinforcing shaft 7 into the first sliding groove 9, fold the secondary ladder section so that it fits against the main ladder section, lift the folding ladder to move it from the limiting groove 4 to the wall connecting section 2, move it close to the wall along the wall connecting section 2, and then lift the folding ladder again so that it passes over the wall-mounted limiting protrusion 12 to limit the folding ladder, thus completing the storage.
