Description

Technical Field

[0001] This utility model relates to the field of elevator equipment technology, and in particular to a rescue ladder for a side-door inclined elevator. Background Technology

[0002] An inclined elevator is a transportation device whose running trajectory is at a certain angle to the horizontal plane, used to transport passengers or goods. A side-door inclined elevator refers to an inclined elevator equipped with vertical doors that are parallel to the vertical plane of the running path of the transport device.

[0003] Side-door inclined elevators typically have a long maintenance and rescue passage on one side of the operating space. When the elevator malfunctions and cannot move, rescuers can use ladders or similar rescue devices to evacuate people from the car to the maintenance and rescue passage.

[0004] Existing side-mounted inclined elevator ladders or rescue devices typically have two legs, one long and one short. During use, these legs are placed on the steps of the maintenance and rescue passage. The inclined placement of the ladder creates a gap between the long and short legs and the steps of the maintenance and rescue passage. Furthermore, the degree of this gap varies depending on the angle at which the ladder is placed, resulting in uneven stress and instability during use, posing safety risks during rescue operations. Utility Model Content

[0005] The purpose of this utility model is to provide a rescue ladder for a side-mounted inclined elevator to solve the safety risk caused by the suspension of the outriggers when using existing rescue ladders.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a rescue ladder for a side-door inclined elevator, comprising:

[0007] The ladder itself;

[0008] The sill seat is installed on the ladder body;

[0009] The short-leg base is installed on the short bottom support leg of the ladder body by means of the first bottom fastening bolt;

[0010] The outrigger adjustment rod is fitted onto the long bottom outrigger of the ladder body. The outrigger adjustment rod is provided with a waist-shaped hole, and the adjustment and fastening bolt passes through the ladder body and the waist-shaped hole.

[0011] The long-legged base is installed at the bottom of the outrigger adjusting rod by the second base fastening bolt.

[0012] As a further description of the above technical solution:

[0013] The sill bracket is fixedly installed on the ladder body by bracket fastening bolts, which pass through the sill bracket and the ladder body.

[0014] As a further description of the above technical solution:

[0015] The outrigger adjustment rod has two waist-shaped holes arranged in a straight line.

[0016] As a further description of the above technical solution:

[0017] Adjust the fastening bolts to quick-release screws.

[0018] As a further description of the above technical solution:

[0019] The adjusting fastening bolt includes a screw, a crank wrench, and an adjusting nut. The crank wrench is rotatably mounted on the screw, and the screw passes through the ladder body, the slotted hole, and then connects to the adjusting nut.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] 1. In this utility model, the short foot base of the short bottom support leg of the ladder body is placed on the higher step of the rescue passage, and the long foot base of the long bottom support leg of the ladder body is placed on the lower step of the rescue passage. By loosening the first bottom foot fastening bolt and the second bottom foot fastening bolt, the short foot base and the long foot base are adjusted to contact the surface of the rescue passage step, so as to avoid suspension and eliminate safety hazards.

[0022] 2. In this utility model, after the short foot base of the short bottom support leg of the ladder body is placed stably, the position of the support leg adjustment rod on the long bottom support leg of the ladder body is adjusted by sliding to make the long foot base contact the surface of the rescue passage step. In this way, the ladder is placed on the rescue passage step with more even force and is more stable during use, so as to further reduce the potential dangers in the rescue process.

Detailed Implementation

[0030] 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.

[0031] Example 1

[0032] Please see Figure 1-4 This utility model provides a technical solution: a rescue ladder for a side-door inclined elevator, comprising:

[0033] Ladder body 1;

[0034] The sill seat 2 is installed on the ladder body 1;

[0035] The short-leg base 5 is installed on the short bottom support leg of the ladder body 1 by means of the first bottom fastening bolt;

[0036] The outrigger adjustment rod 3 is fitted onto the long bottom outrigger of the ladder body 1. The outrigger adjustment rod 3 is provided with a waist-shaped hole 31, and the adjustment fastening bolt 7 passes through the ladder body 1 and the waist-shaped hole 31.

[0037] The long-leg base 4 is installed at the bottom of the outrigger adjusting rod 3 by the second base fastening bolt 6.

[0038] The sill bracket 2 is located in the upper middle part of the ladder body 1, with one on each side of the two vertical bars of the ladder body 1.

[0039] The sill bracket 2 is fixedly installed on the ladder body 1 by the bracket fastening bolt 8, which passes through the sill bracket 2 and the ladder body 1. The sill bracket 2 can be rotated and adjusted by loosening and tightening the bracket fastening bolt 8 to engage with the car door sill 9.

[0040] Working principle: When using the rescue ladder, the ladder body 1 is placed at an angle on the rescue passage step 10. The sill seat 2 is inserted into the slide of the car door sill 9. The short foot base 5 of the short bottom support leg of the ladder body 1 is placed on the higher step of the rescue passage step 10, and the long foot base 4 of the long bottom support leg of the ladder body 1 is placed on the lower step of the rescue passage step 10. By loosening the first foot fastening bolt and the second foot fastening bolt 6, the short foot base 5 and the long foot base 4 are adjusted to contact the surface of the rescue passage step 10 to avoid suspension and eliminate safety hazards. Then the first foot fastening bolt and the second foot fastening bolt 6 are tightened.

[0041] On the other hand, after the short base 5 of the short bottom support leg of the ladder body 1 is placed stably, the position of the support leg adjustment rod 3 on the long bottom support leg of the ladder body 1 is adjusted by sliding so that the long base 4 contacts the surface of the rescue passage step 10. In this way, the ladder is placed on the rescue passage step and the force is more even and it is more stable when in use, so as to further reduce the potential dangers in the rescue process.

[0042] Example 2

[0043] Based on the above embodiments, this embodiment further improves upon the following technical solution: the outrigger adjusting rod 3 is provided with two oblong holes 31 arranged in a straight line to accommodate two adjusting fastening bolts 7, thereby increasing the connection strength of the outrigger adjusting rod 3.

[0044] Example 3

[0045] This embodiment further improves upon the above embodiment by making the following technical solution: the adjusting fastening bolt 7 is a quick-release screw. Specifically, the adjusting fastening bolt 7 includes a screw 71, a crank wrench 72, and an adjusting nut 73. The crank wrench 72 is rotatably mounted on the screw 71, and the screw 71 passes through the ladder body 1 and the oblong hole 31 before connecting to the adjusting nut 73.

[0046] By turning the crank wrench 72, the loosening and tightening of the adjusting bolt 7 on the outrigger adjusting rod 3 can be achieved quickly, thereby quickly adjusting the position of the outrigger adjusting rod 3.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
