[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figures 1 to 5 , a step-type escalator according to an embodiment of the present invention, includes a frame 100, a plurality of steps 200, and a drive mechanism 300. The frame 100 is provided with a step track 110 having an upwardly inclined section 111; the steps 200 are provided with a supporting surface 210, and the steps 200 are movably arranged on the step track 110 and can move along the step track 110; the drive mechanism 300 is provided on the frame 100 and is used to drive the steps 200 to circulate along the step track 110; the plurality of steps 200 are divided into a plurality of groups, each group of steps 200 having three steps 200, and when each group of steps 200 moves to the upwardly inclined section 111 of the step track 110, the supporting surfaces 210 of the steps 200 therein are aligned. The driving mechanism 300 drives the steps 200 to move in a circular motion along the step track 110 of the frame 100. When each group of steps 200 moves to the upper inclined section 111 of the step track 110, the supporting surfaces 210 of the steps 200 are aligned, so that the supporting surfaces 210 of each group of steps 200 are located on the same plane. The supporting surfaces 210 can be used in conjunction with each other to increase the area of the supporting surfaces 210 located on the same plane.

[0032] In the embodiment, each set of steps 200 includes three steps 200. It is conceivable that each set of steps 200 may also include two, four, or more than four steps 200, without being limited to the above embodiment.

[0033] In this embodiment, two adjacent steps 200 in each set of steps 200 are hinged. Hinging the adjacent steps 200 in each set of steps 200 allows for a relatively large support surface 210, making it easier to create, less prone to accidents, and providing improved safety. It also facilitates turning of each set of steps 200. Specifically, the hinged connection can be via a pivot or hinge.

[0034] Specifically, the drive mechanism 300 includes a chain 310 and a drive assembly that drives the chain 310 in a circular motion. In each set of steps 200, one step 200 is hingedly connected to the chain 310. Specifically, the drive assembly includes a reduction motor and a sprocket. The reduction motor is mounted on the frame 100, and the sprocket is pivotally connected to the frame 100. The output shaft of the reduction motor drives the sprocket to rotate. The chain 310 is mounted on the sprocket, and the sprocket drives the chain 310 to move. One step 200 in each set of steps 200 is hingedly connected to the chain 310. The chain 310 can drive the entire set of steps 200 by simply connecting one step 200. This facilitates control of the movement of each set of steps 200 at different positions on the step track 110. The structure is simple and easy to implement. It is conceivable that two or more steps 200 in each set of steps 200 can also be hingedly connected to the chain 310.

[0035] Specifically, the frame 100 is provided with a chain guide groove 400, and the chain 310 is arranged with a plurality of guide wheels 320, which are rolled in the chain guide groove 400. The chain 310 also moves along the chain guide groove 400, wherein one step 200 of each group of steps 200 is hinged to the guide wheel 320.

[0036] It is conceivable that the driving assembly may also be a drive motor and a sprocket, and the sprocket drives the chain 310 to move.

[0037] It is conceivable that the driving mechanism 300 can also be a reduction motor, a gear and a rack, the gear is fixedly set on the output shaft of the reduction motor, and the rack is hinged to one of the steps 200 in each group of steps 200, and the gear drives the rack to move, thereby driving the step 200 to move.

[0038] In this embodiment, in each set of steps 200, one of the two adjacent steps 200 is provided with an abutment portion 220, and the other is provided with a mating portion 230. The abutment portion 220 can abut against the mating portion 230 to limit the relative angular position of the two adjacent steps 200. The provision of the abutment portion 220 and the mating portion 230 prevents large depressions or protrusions between the supporting surfaces 210 of each set of steps 200 in the event of an accident, thereby improving the safety of the step-type escalator.

[0039] In this embodiment, the step track 110 further includes an upper turning section 112, a lower inclined section 113, and a lower turning section 114. The upper inclined section 111 is sequentially connected end to end with the upper turning section 112, the lower inclined section 113, and the lower turning section 114. The step track 110 of the above structure is simple in structure and facilitates the circular movement of each set of steps 200 along the step track 110.

[0040] In this embodiment, the step 200 is provided with a track-engaging portion 240, which enables the step 200 to move along the step track 110 by movably engaging with the step track 110. Specifically, the track-engaging portion 240 is a supporting wheel that is rotatably disposed within the step track 110. It is also conceivable that the track-engaging portion 240 may also be a slider that is slidably disposed within the step track 110.

[0041] Specifically, in each set of steps 200, when all steps 200 are located on the upper inclined section 111, the rail engaging portions 240 are arranged in a straight line, and the arrangement direction is parallel to the upper inclined section 111, so that the supporting surfaces 210 of each set of steps 200 are coplanar in the horizontal direction.

[0042] Specifically, the upper inclined section 111 and the lower inclined section 113 are arranged in parallel, which has a simple structure and is easy to implement.

[0043] In an embodiment, the upper turning section 112 includes upper sub-guide grooves 1121 corresponding one-to-one with each step 200 in each group of steps 200. The upper sub-guide grooves 1121 are arranged parallel to each other. When each group of steps 200 moves to the upper turning section 112, the track-matching portions 240 of each step 200 therein respectively and correspondingly move and mate with the upper sub-guide grooves 1121. Because the distance from the supporting surface 210 of each step 200 in each group of steps 200 to the corresponding track-matching portion 240 is different, the number of track-matching portions 240 corresponds to the number of upper sub-guide grooves 1121, facilitating that each step 200 in each group of steps 200 can turn synchronously with the chain 310. It is conceivable that the number of upper sub-guide grooves 1121 can also be two or more, corresponding one-to-one with the number of track-matching portions 240 in each group of steps 200, facilitating turning of each group of steps 200. It should be understood that when the track fitting portion 240 is a supporting wheel, the track fitting portion 240 is rollingly connected to the upper guide groove 1121. When the track fitting portion 240 is a slider, the track fitting portion 240 is slidingly connected to the upper guide groove 1121.

[0044] In this embodiment, the lower turning section 114 includes lower sub-guide grooves 1141 corresponding one-to-one with each step 200 in each group of steps 200. The lower sub-guide grooves 1141 are arranged parallel to each other. When each group of steps 200 moves to the lower turning section 114, the track-matching portions 240 of each step 200 therein respectively move and match with the lower sub-guide grooves 1141. Because the distance between the supporting surface 210 of each step 200 in each group of steps 200 and the corresponding track-matching portion 240 is different, adjacent steps 200 are hinged. The number of track-matching portions 240 corresponds to the number of lower sub-guide grooves 1141, facilitating the synchronous turning of each step 200 with the chain 310. It is conceivable that the number of lower sub-guide grooves 1141 can be two or more, corresponding one-to-one with the number of track-matching portions 240 in each group of steps 200, to facilitate turning of each group of steps 200. It should be understood that when the track fitting portion 240 is a supporting wheel, the track fitting portion 240 is rollingly connected to the lower guide groove 1141. When the track fitting portion 240 is a slider, the track fitting portion 240 is slidingly connected to the lower guide groove 1141.

[0045] In an embodiment, the upper inclined section 111 is a single-groove structure, the upper turning section 112 includes upper sub-guide grooves 1121 corresponding one-to-one to each step 200 in each group of steps 200, the upper sub-guide grooves 1121 are parallel to each other and arranged vertically, the lower inclined section 113 is a single-groove structure, the lower turning section 114 includes lower sub-guide grooves 1141 corresponding one-to-one to each step 200 in each group of steps 200, the lower sub-guide grooves 1141 are parallel to each other and arranged vertically, the upper end of the upper inclined section 111 is connected to one end of each upper sub-guide groove 1121, the lower end of the upper inclined section 111 is connected to one end of each lower sub-guide groove 1141, the upper end of the lower inclined section 113 is connected to the other end of each upper sub-guide groove 1121, and the lower end of the lower inclined section 113 is connected to the other end of each lower sub-guide groove 1141.

[0046] When the step-type escalator ascends, when each set of steps 200 is in the upper inclined section 111, the guide wheel 320 moves in the single groove structure of the upper inclined section 111; when each set of steps 200 enters the upper turning section 112 from the upper inclined section 111, the driving mechanism 300 drives each set of steps 200 to move along the upper turning section 112. Since the adjacent steps 200 are hinged, the steps 200 can be turned downward synchronously by setting the upper guide grooves 1121 corresponding to the number of the track matching parts 240. After turning, the track engaging portion 240 of each set of steps 200 enters the single groove structure of the lower inclined section 113 and descends along the lower inclined section 113. When each set of steps 200 enters the lower turning section 114 from the lower inclined section 113, the driving mechanism 300 drives each set of steps 200 to move along the lower turning section 114. Since adjacent steps 200 are hinged, the lower sub-guide grooves 1141 corresponding to the number of track engaging portions 240 are provided to allow each step 200 to turn upward synchronously. The step track 110 of the above structure is simple in structure, meets the movement requirements of each set of steps 200, and saves materials.

[0047] Similarly, when a step-type escalator descends, each set of steps moves in the opposite direction 200 degrees, which will not be described in detail here.

[0048] It is conceivable that the step track 110 may also be three circles of mutually parallel guide grooves, and the track matching portion 240 of each step 200 of each group of steps 200 moves in the corresponding guide groove.

[0049] In an embodiment, the upper guide groove 1121 is arranged from the inside to the outside, a first opening 1122 is provided on the upper side of the upper guide groove 1121, and a second opening 1123 is provided on the lower side of the upper guide groove 1121. The first opening 1122 is arranged obliquely in the upper right direction from the inside to the outside, and the second opening 1123 is arranged obliquely in the lower left direction from the inside to the outside. The arrangement of the first opening 1122 and the second opening 1123 of the above structure facilitates the entry and exit of each guide wheel 320 of each set of steps 200 into the corresponding upper guide groove 1121. Preferably, the inclination angle of the arrangement direction of the first opening 1122 relative to the horizontal plane is equal to the inclination angle of the upper inclined section 111, so that each track matching portion 240 can enter the corresponding upper guide groove 1121 at the same time. Preferably, the inclination angle of the arrangement direction of the second openings 1123 relative to the horizontal plane is equal to the inclination angle of the lower inclined section 113 , so that each track fitting portion 240 can leave the corresponding upper guide groove 1121 at the same time.

[0050] In an embodiment, the lower sub-guide groove 1141 is arranged from the inside to the outside, a third opening 1142 is provided on the upper side of the lower sub-guide groove 1141, and a fourth opening 1143 is provided on the lower side of the lower sub-guide groove 1141. The third opening 1142 is arranged obliquely in the upper right direction from the inside to the outside, and the fourth opening 1143 is arranged obliquely in the lower left direction from the inside to the outside. The arrangement of the third opening 1142 and the fourth opening 1143 of the above structure facilitates the entry and exit of each guide wheel 320 of each set of steps 200 into the corresponding lower sub-guide groove 1141. Preferably, the inclination angle of the arrangement direction of the third opening 1142 relative to the horizontal plane is equal to the inclination angle of the upper inclined section 111, so that each track matching portion 240 can easily exit the corresponding lower sub-guide groove 1141. Preferably, the inclination angle of the arrangement direction of the fourth openings 1143 relative to the horizontal plane is equal to the inclination angle of the lower inclined section 113 , so as to facilitate each rail fitting portion 240 to enter the corresponding lower sub-guide groove 1141 .

[0051] In this embodiment, the upper turning section 112 includes an upper semicircular portion 1124 and a mutually parallel upper entry portion 1125 and upper exit portion 1126. The distance L1 between the upper entry portion 1125 and the upper exit portion 1126 is greater than the inner diameter D1 of the upper semicircular portion 1124. The upper end of the upper semicircular portion 1124 is connected to the upper entry portion 1125, and the lower end of the upper semicircular portion 1124 is connected to the upper exit portion 1126. Reducing the diameter D1 of the upper semicircular portion 1124 to be smaller than L1 facilitates the turning of each set of steps 200 in the upper turning section 112, thereby reducing the space occupied by the stepped escalator.

[0052] In this embodiment, lower turning section 114 includes a lower semicircular portion 1144 and a lower entry portion 1145 and a lower exit portion 1146 that are parallel to each other. The distance L2 between lower entry portion 1145 and lower exit portion 1146 is greater than the inner diameter D2 of lower semicircular portion 1144. The lower end of lower semicircular portion 1144 is connected to lower entry portion 1145, and the lower end of lower semicircular portion 1144 is connected to lower exit portion 1146. Reducing the diameter D1 of lower semicircular portion 1144 to be smaller than L1 facilitates the turning of each set of steps 200 in lower turning section 114, thereby reducing the space occupied by the step-type escalator.

[0053] Specifically, the step track 110 is a guide groove, and the step 200 is provided with a track fitting portion 240. The track fitting portion 240 moves in the guide groove, so that the step 200 moves along the step track 110. It is conceivable that the step track 110 can also be a slide rail, with a slider hinged to the step 200, and the slider is slidably arranged on the slide rail.
