Description

Technical Field

[0001] The invention relates to the technical field of escalators, in particular to a bidirectional fine-tuning mechanism for an escalator truss. Background Art

[0002] In the prior art, the height and left-right position adjustment of the escalator truss in the tooling are achieved by a worm gear lift and a large roller respectively. These two are common products on the market and can be purchased and used directly, but the following two problems are inevitably generated in the actual operation process: (1) Due to the influence of the worm gear structure, the height of this lift is also limited. Then, the height of the entire tooling designed on this basis is continuously increased, which ultimately leads to an increase in the production cost and an increase in the difficulty of assembly operation in this huge machine. (2) The rollers required for the left-right position adjustment of the escalator truss mentioned above are independently set and cannot be adjusted up and down or left and right at will. It is necessary to first adjust the left and right on the rollers and then lift them up and down. This makes the operation cumbersome, and the entire set of adjustment devices is not compact and has large external dimensions. Summary of the invention

[0003] In view of the above existing technical problems, the purpose of the present invention is to propose a two-way fine-tuning mechanism for an automatic escalator truss, which is provided with a lifting component with a height adjustment function, which can solve the problem of height limitation of the original mechanism. In addition, a roller with a left and right position adjustment function is integrated on this mechanism, which can realize multi-directional adjustment of the escalator truss to achieve the purpose of precise positioning.

[0004] The technical solution of the present invention is achieved as follows: an escalator truss bidirectional fine-tuning mechanism comprises a base, an adjustment seat movably arranged above the base, and a lifting assembly for driving the adjustment seat to rise and fall; the adjustment seat comprises an upper platform, a slide plate, and a sliding matching assembly;

[0005] The sliding matching assembly includes a hanging plate and a roller; the two hanging plates are arranged opposite to each other on the upper platform; a plurality of rollers are arranged at intervals along the first direction on each hanging plate; each roller has a central axis extending along the second direction; the roller rotates around its central axis; the skateboard is arranged above the roller and has a matching surface abutting against the wheel surface of each roller.

[0006] Furthermore, a limiting flange is provided on the sliding plate corresponding to the hanging plate; the limiting flange extends along the first direction and is limitedly matched with the outer end surface or the inner end surface of the roller on the corresponding side.

[0007] Furthermore, the base includes a lower platform; the upper platform and the lower platform are arranged correspondingly in the upper and lower directions; the lifting assembly includes a wedge-shaped member and a driving member; the two wedge-shaped members are arranged relatively between the upper platform and the lower platform in the horizontal direction; the bottom surface of the wedge-shaped member is provided with a first wedge-shaped surface, and the top surface is provided with a second wedge-shaped surface; the lower platform is provided with a first inclined surface that slides with the first wedge-shaped surface; the upper platform is provided with a second inclined surface that slides with the second wedge-shaped surface; the driving member is used to drive the two wedge-shaped members to move closer to or away from each other in the horizontal direction.

[0008] Furthermore, the driving member includes a screw rod; a left-handed thread section and a right-handed thread section are provided on the screw rod; the wedge member on one side is threadedly connected to the left-handed thread section, and the wedge member on the other side is threadedly connected to the right-handed thread section; the base includes a limit fork arranged on the lower platform; a recessed portion with a top opening is provided on the limit fork; the screw rod is movably arranged in the recessed portion, and limit portions are provided on both sides of the limit fork on the screw rod.

[0009] Furthermore, a limiting space extending in the horizontal direction is formed between the two hanging plates; the wedge-shaped piece is movably arranged in the limiting space in a clearance-fitting manner.

[0010] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0011] The present invention can adjust the position of the escalator truss in the vertical position and the horizontal direction through the coordinated use of the lifting assembly, the roller and the slide plate, thereby realizing the multi-directional adjustment of the escalator truss to achieve the purpose of precise positioning. In addition, through reasonable structural design, under the condition of the same load-bearing capacity, the volume of the fine-tuning mechanism of the present invention is reduced, which not only makes the overall structure more compact and beautiful, but also reduces the production cost of the entire tooling, which is more conducive to assembly work.

DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0021] like Figure 1-6 The figure shows a bidirectional fine-tuning mechanism for an escalator truss according to the present invention, which is used to adjust the position of the escalator truss. The fine-tuning mechanism includes a base, an adjustment seat movably mounted on the base, and a lifting assembly for driving the adjustment seat to rise and fall. The truss is placed on the adjustment seat, and the adjustment seat is driven to rise and fall by the lifting assembly, thereby completing the adjustment of the upper and lower positions of the truss.

[0022] The adjustment seat includes an upper platform 2, a slide plate 3 and a sliding matching component. The sliding matching component includes a hanging plate 21 and a roller 22. Two hanging plates 21 are relatively mounted on the front and rear sides of the upper platform 2. A plurality of rollers 22 are arranged at intervals along a first direction on each hanging plate 21. The first direction in this embodiment is the left-right direction. Each roller 22 has a central axis extending along a second direction. The second direction in this embodiment is the front-back direction. The specific installation method of the roller 22 is that a rotating shaft is fixedly mounted on the hanging plate 21 corresponding to each roller 22, and the roller 22 is mounted on the rotating shaft through a bearing sleeve, so that the roller 22 rotates around the central axis of the rotating shaft. The wheel surface of the roller 22 is made of rubber material. The slide plate 3 is mounted above the roller 22 and has a matching surface that abuts against the wheel surface of each roller 22. Through the above structural design, the slide plate 3 is supported by the roller 22. When the slide plate 3 is pushed to move in the left-right direction, the roller 22 rotates so that the slide plate 3 can move smoothly. The front and rear sides of the slide plate 3 are provided with limit flanges 31 corresponding to the hanging plates 21. The limit flanges 31 extend in the first direction (left-right direction) and are limitedly matched with the outer end surface or the inner end surface of the roller 22 on the corresponding side. In this embodiment, the relative inner side surfaces of the limit flanges 31 on both sides are gap-matched with the outer end surfaces of the rollers 22 on the front and rear sides. When the slide plate 3 moves, it is blocked by the rollers 22 and the slide plate 3 will not deviate from a large position in the front-back direction.

[0023] In this embodiment, the base includes a lower platform 1, a limit fork 11, a guide column 12, and a limit member 14. The limit fork 11, the guide column 12, and the limit member 14 are all installed on the lower platform 1. The upper platform 2 and the lower platform 1 are arranged correspondingly up and down. A guide hole is processed on the upper platform 2, and the guide column 12 cooperates with the guide hole, so that the upper platform 2 can move up and down stably. The aforementioned lifting assembly includes a wedge 6 and a driving member. The two wedges 6 are relatively arranged between the upper platform 2 and the lower platform 1 in the horizontal direction (left and right direction in this embodiment). A first wedge surface 61 is processed on the bottom surface of the wedge 6, and a second wedge surface 62 is processed on the top surface. The first wedge surface 61 and the second wedge surface 62 are arranged to be inclined up and down, wherein, in order to meet the design requirements, the inclined lower ends of the first wedge surface 61 and the second wedge surface 62 are close to each other, and the inclined upper ends are away from each other. A first inclined surface 13 that slides with the first wedge surface 61 on the two wedges 6 is processed at a predetermined position on the lower platform 1. A second inclined surface 23 is machined at a predetermined position on the upper platform 2 to slide with the second wedge surfaces 62 on the two wedge members 6. The driving member is used to drive the two wedge members 6 to move closer to or farther from each other in the horizontal direction (in the left-right direction in this embodiment). When the two wedge members 6 move closer to each other, the upper platform 2 is lifted by the cooperation of the first wedge surface 61 and the first inclined surface 13, the second wedge surface 62 and the second inclined surface 23. When the two wedge members 6 move away from each other, the upper platform 2 is lowered.

[0024] A limiting space extending in the horizontal direction (left and right in this embodiment) is formed between the two hanging plates 21. The wedge pieces 6 on both sides are movably installed in the limiting space in a clearance fit manner. When the wedge piece 6 moves, it is blocked by the hanging plates 21 on both sides, and the position of the wedge piece 6 will not shift in the front-to-back direction. In addition, the aforementioned limiting piece 14 is installed on the front and rear sides of the first inclined surface 13, and the limiting piece 14 is an L-shaped structure with a first long side and a second long side. A limiting space for limiting the forward and backward movement of the wedge piece 6 is formed between the second long sides of the limiting pieces 14 on both sides, thereby further preventing the front-to-back position of the wedge piece 6 from shifting and improving the stability of the movement of the wedge piece 6. A waist-shaped hole is processed on the second long side of the aforementioned fixing piece 14 to achieve the installation and fixation of the base.

[0025] The aforementioned driving member includes a screw rod 4. A left-handed thread section and a right-handed thread section are processed on the screw rod 4. The wedge piece 6 on one side is threadedly connected to the left-handed thread section, and the wedge piece 6 on the other side is threadedly connected to the right-handed thread section. By rotating the screw rod 4 forward and backward, the wedge pieces 6 on both sides can be moved closer to or farther away from each other. The aforementioned limiting fork 11 has a recessed portion 111 with a top opening. The screw rod 4 is movably installed in the recessed portion 111, and limiting portions 41 are installed on both sides of the limiting fork 11 on the screw rod 4. Due to the limitation of the limiting portion 41, the screw rod 4 will not move in the left and right directions. At the same time, when the wedge pieces 6 on both sides are driven to move closer to or farther away from each other, the screw rod 4 can rise or fall in the recessed portion 11. A hand wheel 5 is installed at one end of the screw rod 4 to facilitate the rotation of the screw rod 4.

[0026] When in use, the truss of the escalator is placed on the slide plate 3, and the position of the truss is adjusted in the left and right directions by pushing the slide plate 3. The screw rod 4 is rotated forward and backward to complete the lifting and lowering of the adjustment seat, thereby completing the adjustment of the upper and lower positions of the truss.

[0027] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
