[0002] Patent publication number: CN222612678U, the patent name is a utility model patent for an automatic electric lifting escalator and its installation structure. It is the previous generation product of our company. In the process of implementing the renovation of old staircases, it was found that the motor is installed under the stairs, which requires drilling holes in the old stairs to insert the traction rope. The drilling operation is very troublesome. If the internal steel bars of the stairs are hit, it will affect the installation position. Moreover, the drilling noise is very disturbing to the residents. The drilling operation takes a long time, which affects the promotion and application of old staircase renovation projects. Therefore, the inventor wanted to design an lifting escalator that eliminates the need for drilling and threading. Utility Model Content

By mounting the motor on the foot platform and moving it with the foot platform, the motor installation is made more convenient, avoiding cumbersome operations such as drilling holes and threading wires in the staircase, and facilitating the promotion of elevator renovation.

[0004] The technical solution of this utility model is: a lifting ladder for the transformation of staircases, including a pair of rails for installation on both sides of the staircase, and a foot platform slidably installed on the pair of rails, characterized in that: a rotating shaft is rotatably connected to the foot platform and extends horizontally through the foot platform, a reel is installed at both ends of the rotating shaft, a wiring groove is opened on the outer periphery of the reel, and a traction rope is wound through the wiring groove, and a motor for driving the rotating shaft is installed on the foot platform.

[0005] Preferably, the foot pedal platform includes a pedal, one end of which is provided with a first outer side plate, and the other end is provided with a partition and a second outer side plate. A cavity is provided between the partition and the second outer side plate, and the motor is installed in the cavity.

[0006] Preferably, a set of crossbeams is provided below the foot platform, the crossbeams passing through the partition plate and being connected to the first outer side plate, the partition plate and the second outer side plate respectively.

[0007] Preferably, the motor is a geared motor.

[0008] Preferably, the width of the wiring groove is adapted to the outer diameter of the traction rope.

[0009] Preferably, a cross plate is connected between the top of the partition and the top of the second outer side plate.

[0010] Preferably, the track is made of channel steel.

[0011] Preferably, the first outer side plate and the second outer side plate are provided with a set of support wheels on the end face near the opening of the channel steel, which are in rolling contact with the bottom surface of the channel steel.

[0012] Preferably, the first outer side plate and the second outer side plate are provided with a set of guide wheels on the end faces of the first outer side plate and the second outer side plate near the opening of the channel steel, which are in rolling contact with the inner side of the channel steel.

[0013] Compared with the prior art, this utility model has the following advantages: by installing the motor on the foot platform, the installation of the motor is more convenient, avoiding cumbersome operations such as drilling holes and threading wires in the stairs, and making it easier to promote elevator renovation.

[0014] The width of the wiring groove is matched with the outer diameter of the traction rope, so that the traction rope is wound into the groove in a spiral shape, thereby avoiding lateral swinging in the traction rope groove and making winding and release more stable.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0022] like Figures 1 to 4 A type of elevator for the renovation of staircases includes a pair of rails 1 installed on both sides of the staircase, and a foot platform 8 is slidably installed on the pair of rails 1. A pivot 14 that runs horizontally through the foot platform 8 is rotatably connected to the foot platform 8.

[0023] Two reels 3 are installed at both ends of the rotating shaft 14. A wiring groove is provided on the outer periphery of the reel 3, and a traction rope 2 is wound through the wiring groove. A motor 11 that drives the rotating shaft 14 is installed on the foot platform 8.

[0024] The foot platform 8 includes a pedal 5, one end of which is provided with a first outer plate 4, and the other end is provided with a partition 6 and a second outer plate 7. A cavity is provided between the partition 6 and the second outer plate 7, and the motor 11 is installed in the cavity.

[0025] Working principle: When in use, install the elevator on the staircase that needs to be modified, and then fix the free ends of the two traction ropes 2 to a position near the top of the track 1, or to the side walls of the staircase, etc.

[0026] The motor 11 drives the reel 3 to rotate, winding or releasing the traction rope 2, thereby pulling the motor 11 and the foot platform 8 to slide up and down the track together.

[0027] This utility model makes motor installation more convenient by mounting the motor on the foot platform. In the previous generation, the drive motor was installed under the stair platform, which required drilling holes in the staircase and threading wires for traction installation and other cumbersome operations. With the improvement of this application, the installation is convenient and there is no need to drill holes in the staircase, which makes it easier to promote elevator renovation. Example 2

[0028] This embodiment is a further optimization based on the above embodiment, specifically:

[0029] like Figure 2 A set of crossbeams 9 are provided below the foot platform 8. The crossbeams 9 pass through the partition plate 6. The crossbeams 9 are connected to the first outer plate 4, the partition plate 6 and the second outer plate 7 respectively. A cross plate 10 is connected between the top of the partition plate 6 and the top of the second outer plate 7, thereby increasing the overall structural strength of the foot platform 8.

[0030] like Figure 1 and Figure 4 The motor 11 is a geared motor 11. By reducing the output speed and increasing the rotational torque, the lifting and lowering of the foot pedal platform 8 is more stable.

[0031] like Figure 4 The width of the wiring groove is matched with the outer diameter of the traction rope 2, so that the traction rope 2 is wound into the groove in a spiral shape, thereby avoiding lateral swinging in the groove of the traction rope 2, and making the winding and release more stable. Example 3

[0032] This embodiment is a further optimization based on the above embodiment, specifically:

[0033] like Figure 1 and Figure 3 The track 1 is made of channel steel. The first outer plate 4 and the second outer plate 7 are provided with a set of support wheels 12 that roll in contact with the bottom surface of the channel steel.

[0034] A set of guide wheels 13 are provided on the end faces of the first outer plate 4 and the second outer plate 7 near the opening of the channel steel, which are in rolling contact with the inner side of the channel steel.

[0035] The foot platform 8 is slidably connected to the track 1 by the support wheel 12 and the guide wheel 13. The support wheel 12 is used to bear the weight, and the guide wheel 13 is used to guide, so that the foot platform 8 slides more smoothly and stably along the track 1.

[0036] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
