Description

Technical Field

[0001] The utility model relates to the technical field of escalators, in particular to an automatic electric escalator and a mounting structure thereof. Background Art

[0002] At present, some old communities still use traditional stairs to go up and down the stairs. In order to facilitate the travel of the elderly, patients and pregnant women, many communities have installed electric escalators on the stairs.

[0003] The traditional electric escalator is composed of tracks, pedals and winches. The tracks are made of channel steel with the opening facing upward or inward, a slider is slidably installed in the opening, the pedals are installed on the slider, and then the winch is used to pull the slider to drive the pedals to rise and fall.

[0004] However, in actual use, it is found that garbage is easily accumulated in the track, resulting in unsmooth operation. In addition, the traditional winch uses an axial spirally wound roller, which needs to swing left and right when winding the rope. This causes the sliders on both sides of the track to move up and down in an unsynchronized manner, resulting in unsmooth sliding of the pedals or even jamming.

[0005] In addition, when the winch is wound around the wire rope and the slider slides along the rail, friction will generate a lot of noise, which will greatly reduce the user experience and may even cause noise nuisance to others. Summary of the invention

DETAILED DESCRIPTION

[0039] The utility model is further described below with reference to the accompanying drawings and embodiments. Example 1

[0040] like Figure 1 and Figure 2 An automatic electric escalator comprises a winch 1, a track 2 and a control system for controlling the winch 1.

[0041] Track 2 is a pair of inclined arrangements. The longitudinal section of track 2 is a concave structure with an opening facing outward. Track 2 is made of channel steel, and the outward design prevents dust and debris on the stairs from entering and accumulating.

[0042] like Figure 3 A slider 24 is provided in the groove of the track 2. The slider 24 slides along the length direction of the track 2. A rope is connected to the upper end of the slider 24. The rope is made of steel wire rope. The other end of the rope passes through the groove upward along the groove of the track 2 and is connected to the roller 9 of the winch 1. The rope is hidden in the track 2 for a more beautiful appearance, and the track 2 protects the rope.

[0043] The hoist 1 includes a motor 8, a rotating shaft 11 and two sets of rollers 9. The output shaft of the motor 8 is connected to the rotating shaft 11. Figure 4 The longitudinal section of the rotating shaft 11 is a hexagonal structure. Each winding roller 9 includes two limiting plates 14. The center hole of the limiting plates 14 is adapted to the shape and size of the rotating shaft 11 and is slidably mounted on the rotating shaft 11.

[0044] The outer sides of the two limiting plates 14 are both provided with step blocks 12 , and the step blocks 12 are threadedly connected with bolts 16 for tightening the rotating shaft 11 . The position of the limiting plates 14 can be adjusted by loosening the bolts 16 .

[0045] The gap between the two limit plates 14 forms a wire winding groove 15, and the inner side surfaces of the two limit plates 14 are fixed with a non-metallic silencer plate 13. The non-metallic silencer plate is generally made of plastic or ceramic. By adding two non-metallic silencer plates on the inner side surface of the wire winding groove 15, the friction between the rope and the wire winding groove 15 can be reduced, which can eliminate noise and protect the rope.

[0046] The inner width of the wire winding groove 15 is adapted to the outer diameter of the rope. When the winch 1 is started, the rope is arranged in a spiral winding manner in the wire winding groove 15. Compared with the spiral winding method of the traditional winch 1, the swing of the rope and the problem of occupying a large space are avoided. Moreover, this design can synchronize the rope pulling distances in the two side tracks 2.

[0047] The outer side of the slider 24 is connected with a vertical board 4 , a pedal 5 is connected between the two vertical boards 4 , and a folding seat 3 is detachably mounted on one side of the vertical boards 4 .

[0048] The control system includes a controller and a top proximity switch 18 , a bottom proximity switch 19 , a top touch switch 17 , a bottom touch switch 20 , a remote controller and a start switch 6 connected to the controller.

[0049] like Figure 5 and Figure 6 The top proximity switch 18 and the top touch switch 17 are used to control the active stop of the winch 1 and the emergency stop of the winch 1 when the pedal 5 runs to the top of the slide rail, and the bottom proximity switch 19 and the bottom touch switch 20 are used to control the active stop of the winch 1 and the emergency stop of the winch 1 when the pedal 5 runs to the bottom of the slide rail.

[0050] The position of the pedal 5 is monitored by the proximity switches at the upper and lower ends. When the pedal 5 is detected, the winch 1 is controlled to slow down and brake. On this basis, touch switches are added on the upper and lower sides of the two proximity switches for further insurance. When the proximity switch is damaged, the position of the pedal 5 is monitored by the touch switch, and then the winch 1 is controlled to brake urgently. This design is safer and more reliable.

[0051] In addition, the start switch 6 is installed on one of the side vertical plates 4. A handle-type switch is generally selected. When the user stands on the pedal 5, the start switch 6 can be held to start the operation. The start switch 6 and the remote control are both used to control the start and stop of the winch 1. Example 2

[0052] This embodiment is optimized based on the above embodiment, specifically:

[0053] like Figure 6 and Figure 7 The pedal 5 is in an inverted L-shaped structure, and a group of upper shielding photoelectric sensors 22 for monitoring whether there are obstacles in the upward direction of the pedal 5 are provided on the outer edge of the lateral end of the inverted L-shaped structure.

[0054] A group of lower shielding photoelectric sensors 21 for monitoring whether there are obstacles in the downward direction of the pedal 5 are arranged on the outer side of the longitudinal end of the inverted L-shaped structure. The above-mentioned shielding photoelectric sensors are connected to the controller.

[0055] When the shielding photoelectric sensor moves up and down with the pedal 5, once it detects that there is an object in the running direction, it will control the winch 1 to brake urgently through the controller to avoid the influence of debris on the stairs on the elevator operation, which is safer and more reliable. Example 3

[0056] This embodiment is optimized based on the above embodiment, specifically:

[0057] like Figure 3 A set of vertically arranged load-bearing wheels 23 and a horizontally arranged first guide wheel 25 are installed on the slider 24. The load-bearing wheels 23 are in rolling contact with the inner bottom surface of the groove of the track 2, and the first guide wheel 25 is in rolling contact with the inner side surface of the groove of the track 2.

[0058] The bottom of the pedal 5 is connected to a transversely arranged second guide wheel 30 via a bracket 26 , and the second guide wheel 30 is in rolling contact with the outer side surface of the track 2 .

[0059] The bearing wheel 23 and the guide wheel are in rolling contact with the track 2 to avoid friction between the slider 24 and the track 2, so that the slider 24 moves more smoothly and the noise problem caused by sliding friction is avoided. Example 4

[0060] This embodiment optimizes the installation structure based on the above embodiment, specifically:

[0061] The installation structure specifically comprises a staircase foundation and the above-mentioned automatic electric lifting escalator.

[0062] like Figure 8 The staircase foundation includes an inclined step ladder 29 and a platform 27 connected to the top of the step ladder 29, and a pair of tracks 2 are symmetrically laid on both sides of the upper end of the step ladder 29.

[0063] The winch 1 is installed at the bottom of the platform 27, a fixed pulley 7 for supporting the reversal of the rope is installed on the top of the platform 27, and a threading hole 28 for the rope to pass through is opened on the platform 27.

[0064] By reversing the rope downwards through the fixed pulley 7 and passing the rope downwards through the threading hole 28 through the platform 27 , the winch 1 can be installed at the bottom of the platform 27 , which is more aesthetically pleasing and avoids the winch 1 occupying the space above the platform 27 .

[0065] Since the rotating shaft 11 of the winch 1 is matched with the width of the ropes on both sides, the whole is relatively long. A set of shaft seats 10 can be installed at the bottom of the step ladder 29 or the platform 27. A shaft sleeve is rotatably connected inside the shaft seat 10. The inner hole of the shaft sleeve is fixedly connected to the rotating shaft 11, and the shaft seat 10 is positioned by the shaft seat 10.

[0066] In addition, the horizontal height of the upper end surface of the pedal 5 is consistent with the horizontal height of the first step of the step ladder 29, which is convenient for users to step on.

[0067] The present invention is not limited to the above-mentioned implementation modes. Within the knowledge scope of those skilled in the art, various changes can be made without departing from the purpose of the present invention. The changed contents still belong to the protection scope of the present invention.
