Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

The embodiment of the application provides an escalator for carry out automatic conveying with the pedestrian between two places of fixed setting, in order to overcome complicated topography obstacle, avoid the pedestrian to walk, alleviate pedestrian's physical power loss.

The escalator is a fixed electric driving device which is formed by combining a chain conveyor with a special structure form and two belt conveyors with a special structure form, is provided with a circulating movement ladder way and is used for conveying passengers upwards or downwards at different story heights of a building.

Specifically, it may be a continuous transport machine having a walk-substituting property in which a carrier moves up and down. The escalator consists of a ladder way and handrails at two sides. The main components of the device comprise steps, a traction chain and a chain wheel, a guide rail system, a main transmission system (comprising a motor, a speed reducer, a brake, an intermediate transmission link and the like), a driving main shaft, a ladder way tensioning device, a handrail system, a comb plate, a ladder framework, an electric system and the like. The stairs horizontally move at the entrance of the passenger so as to facilitate the passenger to climb the stairs and gradually form the stairs later; the steps gradually disappear near the exit, and the steps move horizontally again so as to facilitate passengers to get off the stairs.

The escalator has truss structure as its main bearing skeleton. It is easy to understand that the truss is usually a steel framework structure formed by welding or assembling steel members and is used for being installed in a construction site so as to bear a main transmission system, a guide rail system, a step system and the like.

For some escalators or moving walkways with large spans and without intermediate support (due to hoistway size limitations or for aesthetic reasons at the installation site), the structural strength and rigidity of the truss structure, as well as the manufacturing cost and processing difficulty, are two opposing contradictory points that need to be considered heavily in the design stage. The truss structure with the new structure can well take the two contradiction points into consideration.

For example, in some embodiments, the truss structure includes an upper horizontal section truss, a middle diagonal section truss, and a lower horizontal section truss. As the name suggests, the middle inclined section truss is a truss section which is inclined at a certain angle, and the arrangement aim is to meet the requirement of connection between two places with height difference. The upper horizontal section truss is connected to one end, with the potential of the middle inclined section truss being high, of the middle horizontal section truss, and the lower horizontal section truss is connected to one end, with the potential of the middle inclined section truss being low, of the middle horizontal section truss. Namely, during installation, the upper horizontal section truss needs to be installed at one of the places with higher potential, so that one end with higher potential of the middle inclined section truss can be fixed; and the lower horizontal section truss needs to be installed at another place with a lower pose so as to fix the lower end of the middle inclined section truss, thereby completing the installation and fixation of the whole truss structure.

The truss structure is used for supporting the stair system, the stair system comprises a plurality of stair blocks 10 which are connected in series to form an annular structure, the stair blocks 10 can roll on the truss structure through stair rollers and can circulate in the annular direction, and people can be transported from a place with high potential to a place with low potential or transported from a place with low potential to a place with high potential.

It will be appreciated that the step blocks 10 of the above described arrangement are primarily intended for use in escalators, in order to support a load bearing member on which a person is standing. Generally speaking, when in use, the step blocks 10 need to be installed on a truss of an escalator, so that the step system formed by the step blocks 10 can be ensured to normally circulate and operate. When the steps are transported from the manufacturing factory to the installation and use place, the step blocks 10 are generally stacked and stored in consideration of their special structural shape and transportation space.

That is, as shown in fig. 1, there is also provided a step stacking and positioning structure in the present application, which includes two step blocks 10 as described above, and two step blocks 10 are stacked in the longitudinal direction. Also in the present embodiment, the step block 10 includes: a step body and a support bracket 13. Wherein, the step body includes footboard 11 and kickplate 12, and kickplate 12 is connected in the rear end of footboard 11 integratively or detachably, and kickplate 12 and footboard 11 are the angular arrangement (usually the acute angle is arranged). The pedal 11 is a direct execution part for bearing and supporting people to stand, and the tread surface of the pedal is provided with anti-skidding lines for enhancing the stability of people to stand and avoiding slipping and falling. The kick plate 12 is provided to prevent people from kicking the step block 10, which may cause damage to the step block 10.

Support bracket 13 with this body coupling of step is fixed, specifically support bracket 13 forms into C type support body, and its both ends are integrative respectively or can dismantle connection footboard 11 and kickplate 12 to make the three enclose and establish the step piece that constitutes the cartridge type structure, wherein the support bracket 13 of C type structure can effectively promote the overall structure intensity and the stability of step piece 10.

Referring to fig. 2, the side of the support bracket 13 facing away from the step body is respectively provided with a positioning protrusion 14 and a positioning slot 15, and the positioning protrusion 14 and the positioning slot 15 are arranged on the support bracket 13 at an interval along the flow direction of the step block 10. When two step blocks 10 are vertically stacked and placed in the packaging and transporting process, the positioning clamping protrusions 14 on the two step blocks 10 are correspondingly matched and clamped with the positioning clamping grooves 15 in a one-to-one correspondence mode.

With continuing reference to fig. 1 and fig. 2, in summary, the implementation of the technical solution of the above embodiment has the following advantages: in this embodiment, taking the minimum stacking structure composed of two step blocks 10 as an example, when placing, the two step blocks 10 are stacked in the height direction, wherein the step block 10 located below is set as a basic step block, and the step block 10 located above is set as an adjacent step block. At this time, the step bodies of the basic step blocks are arranged downwards, the supporting brackets 13 are arranged upwards, and correspondingly, the step bodies of the adjacent step blocks are arranged upwards, and the supporting brackets 13 are arranged downwards, so that before formal stacking and placing, only the positioning clamping protrusions 14 on the basic step blocks are required to be vertically aligned with the positioning clamping grooves 15 on the adjacent step blocks, and simultaneously the positioning clamping grooves 15 on the basic step blocks are required to be vertically aligned with the positioning clamping protrusions 14 on the adjacent step blocks, and in a vertical plane, the adjacent step blocks above can be placed downwards in a vertical downward direction or in a slightly deviated oblique downward direction, so that the positioning clamping protrusions 14 can be ensured to be accurately inserted into the positioning clamping grooves 15, the stacking and placing operation difficulty can be effectively reduced, and the stacking operation efficiency is improved. And, with the help of protruding 14 of two sets of matching location card and the 15 joint of positioning groove, can accomplish quick, the firm equipment of piling up of basic step piece and adjacent step piece, do not need to additionally adopt the packing locating support this moment, can effectively reduce packing cost of transportation, promote enterprise's economic nature.

With reference to fig. 2, based on any of the above embodiments, in some embodiments, the step piece 10 further includes a first positioning protrusion 16 and a second positioning protrusion 17, the first positioning protrusion 16 and the second positioning protrusion 17 are disposed on the support bracket 13 at an interval along a direction perpendicular to a flowing direction of the step piece 10, and the positioning slot 15 is formed between the first positioning protrusion 16 and the second positioning protrusion 17. So, set up with the help of the interval of first location convex body 16 and second location convex body 17, can form positioning channel groove 15 for positioning channel groove 15's formation mode and simple structure do benefit to and reduce design manufacturing cost, and the practicality is strong.

In addition, in some embodiments, the positioning slot 15 is formed as a through slot structure with two ends penetrating. Particularly, the positioning clamping groove 15 is a straight through groove in a straight shape, so that the structure is simple, certain manufacturing and machining dimension errors of the positioning clamping protrusions 14 can be allowed, and the positioning clamping protrusions 14 can be reliably inserted into the positioning clamping groove 15 even if the length of the positioning clamping protrusions is larger than that of the positioning clamping groove 15.

Alternatively, as an alternative to the above embodiment, the positioning slot 15 may be formed as a blind slot structure with one end penetrating and the other end being closed. At this moment, the closed end can abut against the end part of the positioning clamping protrusion 14, and the positioning protrusion inserted into the positioning clamping groove 15 plays a role in positioning and limiting, so that the two step blocks 10 which are stacked are assembled in place and connected stably.

In particular, on the basis of any of the above embodiments, the notch portion of the first positioning protrusion 16 and/or the second positioning protrusion 17 near the positioning slot 15 is provided with a guiding inclined surface. Because, with the help of the guiding function of the leading-in inclined plane, the positioning clamping protrusion 14 can be inserted into the positioning clamping groove 15 more easily, and the positioning clamping protrusion 14 and the clamping groove are allowed to form a certain size of transverse dislocation, so that the inserting reliability of the positioning clamping protrusion 14 and the positioning clamping groove 15 is greatly improved, and the inserting operation difficulty is reduced.

Preferably, the first positioning convex body 16 and the second positioning convex body 17 are provided with leading-in inclined planes at the positions close to the notches of the positioning clamping grooves 15, and at the moment, the two leading-in inclined planes are matched to form a flaring structure, so that the positioning clamping convex 14 can be more easily inserted into the positioning clamping grooves 15. As will be readily understood, the inclined direction of the lead-in slope is inclined outward from the groove bottom to the notch.

Or, in other embodiments, the first positioning protrusion 16 and/or the second positioning protrusion 17 are provided with a first wedging inclined surface around the side wall of the positioning slot 15. Suitably, at least one of the two opposite side surfaces of the positioning plug 142 perpendicular to the flowing direction of the step block 10 is provided with a second wedging inclined surface.

Therefore, in the process that the positioning clamping protrusion 14 is inserted into the positioning clamping groove 15, the first wedging inclined surface can be gradually wedged with the second wedging inclined surface, so that the composite acting force of the clamping force and the wedging force is formed between the positioning clamping protrusion 14 and the positioning clamping groove 15, and the assembly and the positioning of the stacked basic step blocks and the adjacent step blocks are firmer.

It should be noted that, the inclination and the inclination direction of the first wedging inclined plane need to be correspondingly adapted to the inclination and the inclination direction of the second wedging inclined plane, so as to ensure a good wedging effect.

With reference to fig. 1 and fig. 2, on the basis of any of the above embodiments, the positioning snap 14 includes a snap body 141 and a positioning plug 142 connected to the snap body 141. Specifically, the convex body 141 is a rectangular protrusion extending in a direction perpendicular to the circulation direction of the step 10, and the positioning insertion body 142 is a rectangular protrusion extending in a direction parallel to the circulation direction of the step 10 and integrally and vertically connected to the convex body 141. That is, the protruding body 141 of card forms the arrangement of T type structure with the location plug-in body 142 this moment, and not only simple structure to the location plug-in body 142 inserts easily in the location draw-in groove 15, and protruding body 141 of card can strengthen the structural strength of location plug-in body 142, prevents that the root of location plug-in body 142 from breaking.

With reference to fig. 2, a first positioning mating surface 18 and a second positioning mating surface 19 are formed between the positioning plug 142 and the protruding body 141, and the first positioning mating surface 18 is opposite to the second positioning mating surface 19. Also be first location fitting surface 18 and second location fitting surface 19 for two L type sides of the protruding 14 of the locator card of T type structure, these two L type sides can respectively with the medial surface and the terminal surface of first location convex body 16, and the medial surface and the terminal surface butt of second location convex body 17, thereby effectively the restriction piles up the degree of freedom of X axle and Y axle direction in the horizontal plane of two step pieces 10 placed, thereby it is more firm to guarantee to pile up the equipment, even when receiving external vibration or when assaulting, two step pieces 10 are difficult for taking place the pine and take off.
