Summary of the Invention

[0003] The purpose of the present invention is to provide an escalator with heightened protective glass to solve the problems existing in the prior art; the purpose of the present invention is also to provide a fixing device for fixing the heightened protective glass in the escalator.

[0004] To achieve the above - mentioned purpose, an escalator with heightened protective glass of the present invention adopts the following technical solutions:

[0005] An escalator with heightened protective glass includes a handrail device and heightened protective glass. The handrail device includes a side truss. The heightened protective glass is fixed outside the side truss through a fixing device. The fixing device includes a plug - in fixing piece, a locking wedge block and a support groove. The plug - in fixing piece includes a first installation groove and a second installation groove with the notch facing upward. The thickness of the first installation groove is adapted to the thickness of the vertical section of the side truss to be clamped under the side truss. A fixing structure is provided between the plug - in fixing piece and the side truss. The size of the second installation groove is adapted to the thickness of the support groove for the support groove to be inserted therein. The support groove is in a U - shape with the opening facing upward and the opening size is adapted to the thickness of the heightened protective glass for it to be inserted. The locking wedge block includes a cavity adapted to the shape of the outermost support column of the plug - in fixing piece. At least one pair of end faces of the cavity or at least one pair of end faces of the locking wedge block are inclined planes with the distance between the corresponding pair of end faces gradually increasing from top to bottom. A light hole is opened at the lower end of the locking wedge block and communicates with the cavity. A threaded hole is opened at the upper end of the outermost support column. The locking wedge block is fixed on the support column through a bolt. The locking wedge block includes a pressing surface adapted to the outer side surface shape of the heightened protective glass to press it against the inner wall surface of the support groove.

[0006] The front and rear end faces of the cavity are inclined planes that gradually approach the inside from top to bottom, and the front and rear end faces of the cavity are symmetrically arranged.

[0007] The locking wedge block is a U-shaped structure with an opening downward. The cavity is formed between the two side plates of the locking wedge block, and the light hole is opened on the web of the locking wedge block.

[0008] The inner side surface of the locking wedge block is a flat surface that fits the outer side surface of the heightened protective glass to form the pressing surface.

[0009] The outermost support column of the plug-in fixing member has the greatest height, and the outer side plate of the bracket has a lower height than the inner side plate so that the inner side surface of the locking wedge block can press the outer side surface of the heightened protective glass after being locked on the plug-in fixing member.

[0010] A plurality of reinforcing beams extending along the length direction of the bracket are arranged vertically inside the inner side plate of the bracket.

[0022] An embodiment of an escalator with heightened protective glass according to the present invention:

[0023] The specific structure of an escalator with heightened protective glass according to the present invention is as shown in Figures 1 to 6 and includes a handrail device 100 and heightened protective glass 200. The handrail device 100 includes a handrail 11, a side truss 12, and a skirt board 13 located below the handrail 11. The heightened protective glass 200 is located outside the skirt board 13, and the lower end of the heightened protective glass 200 is fixed to the outside of the side truss 12 through a fixing device 300.

[0024] The fixing device 300 includes a plug-in fixing part 31, a locking wedge 32, a column 34, a fixed baffle 35, a bracket 36 and an upper surrounding frame 37. The side truss 12 is L-shaped. The plug-in fixing part 31 includes a first installation groove 311 and a second installation groove 312 with the notch facing upward. The thickness of the first installation groove 311 is adapted to the thickness of the vertical section of the side truss 12 so as to be sleeved under the vertical section, and then the plug-in fixing part is fixed to the side truss 12 by welding. The welding structure forms a fixing structure for fixing the plug-in fixing part 31 at the lower end of the side truss 12. The size of the second installation groove 312 is adapted to the width of the bracket 36 for the bracket 36 to be inserted therein. The bracket 36 is U-shaped with the opening facing upward. The width of the middle opening of the bracket 36 corresponds to the thickness of the heightened protective glass 200 for the heightened protective glass 200 to be inserted therein. The heightened protective glass 200 is pressed and fixed on the inner side wall of the bracket 36 by the locking wedge 32. The locking wedge 32 is sleeved on the outermost support column 313 of the plug-in fixing part 31 and is connected to it by a bolt 33. The fixing of the middle part of the heightened protective glass 200 is realized by the cooperation of the locking wedge 32 and the plug-in fixing part 31. The locking wedge 32 is U-shaped with the opening facing downward, and the inner wall surfaces of its two side plates 321 are symmetrical inclined surfaces so that its opening width increases sequentially from top to bottom. A threaded hole 314 is opened at the upper end of the support column 313, and a clearance hole 323 is opened on the web 322 of the locking wedge 32. After the locking wedge 32 is sleeved on the support column 313, the bolt 33 passes through the clearance hole 323 and the threaded hole 314 in sequence. When the bolt 33 is screwed, the locking wedge 32 will move up and down relative to the support column 313 to tighten or loosen the cooperation relationship with the support column 313. At the same time, the cooperation of the bolt 33 and the threaded hole 314 can also lock the locking wedge 32 to prevent the locking wedge from loosening.

[0025] Two L-shaped fixed baffles 35 are used in a group. One side plate of a group of fixed baffles 35 is fixed at the end of the bracket 36 or the corresponding end of the side truss 12. The opposite two side plates in a group of fixed baffles 35 cooperate to clamp the column 34 to realize the limit of the column 34. The upper surrounding frame 37 includes an opening facing downward to be sleeved on the heightened protective glass and the upper end of the column. The lower ends of the two side plates of the upper surrounding frame 37 are bent inward to better fit the two side walls of the heightened protective glass 200. The column 34 is convex-shaped with a thin upper end and a thick remaining part. The thickness of the upper end matches the thickness of the heightened protective glass 200 for the upper surrounding frame 37 to be sleeved, and the larger thickness of the remaining part can not only better position the heightened protective glass 200 but also facilitate clamping and fixing it by a group of fixed baffles 35.

[0026] In this embodiment, the inner side surface of the locking wedge block 32 is a flat surface so that it can be closely attached to the outer side surface of the heightened protective glass 200 to form a pressing surface. In other embodiments, the pressing surface on the inner side of the locking wedge block 32 can also be processed into an inclined surface that gradually inclines inwards from top to bottom, so that when the locking wedge block 32 moves downwards, the distance between it and the heightened protective glass 200 will gradually decrease to clamp the heightened protective glass more tightly.

[0027] In this embodiment, the plug-in fixing member 31 is machined and formed to ensure the thickness of each part of the material and thus ensure the overall strength. Among them, the outermost support column 313 of the plug-in fixing member 31 has the greatest height to ensure that after the locking wedge block 32 is tightly installed, its pressing surface will directly press on the outer side surface of the heightened protective glass 200 and will not be blocked by the outer side wall of the support groove 36.

[0028] In this embodiment, the upright column 34 is used to limit the front and rear ends of the heightened protective glass 200, and the upper surrounding frame 37 is used to limit the upper end of the heightened protective glass 200. Together with the plug-in fixing member 31 and the locking wedge block 32, the locking of the heightened protective glass 200 is realized. In other embodiments, an installation groove for the corresponding end of the heightened protective glass to be inserted into can also be opened on the side surface of the upright column 34.

[0029] In this embodiment, the height of the outer side plate 362 of the support groove 36 is lower than the height of the inner side plate 361. A plurality of reinforcing beams 363 extending along the length direction of the support groove 36 are arranged at intervals in the inner side plate 361 in the up and down direction. The thickness of the locking wedge block 32 is greater than the thickness of the outermost support column 313 of the plug-in fixing member 31. After the locking wedge block 32 is locked, its inner side is placed on the outer side plate 362 of the support groove 36. In this form, the outer side plate 362 of the support groove 36 can limit the locking wedge block 32 to indicate that the installation is in place. In other embodiments, the inner and outer side plates of the support groove 36 can also be of equal height. At this time, it is necessary to appropriately increase the height of the support column 313 so that the lower end of the locking wedge block 32 can be placed on the outer side plate 362 of the support groove 36; the reinforcing beam 363 on the support groove 36 can also be omitted. In this case, the support groove 36 needs to be made of a material with higher strength or the thickness of the plate is increased to increase the strength of the support groove 36. At the same time, it is not convenient to adjust the opening size in the support groove 36 to match the thickness of the heightened protective glass 200.

[0030] In other embodiments, when the inner side surface of the locking wedge block 32 is processed into an inclined surface that gradually inclines outwards from top to bottom, the lower end of the inner side surface of the locking wedge block 32 can also be flush with the lower end of the inner side surface of the support column 313. In this case, the upper end of the inner side surface of the locking wedge block 32 can also press on the outer side surface of the heightened protective glass 200 after the locking wedge block 32 is locked.

[0031] In other embodiments, the locking wedge block 32 can also be in the shape of a cuboid. In this case, a cavity with a lower opening needs to be formed in the middle thereof. The size of the cavity should match the shape of the outermost support column 313 so as to be sleeved thereon. The inclined surfaces should be arranged on the front and rear end faces of the cavity. The lower end of the light hole formed at the upper end of the locking wedge block 32 should communicate with the cavity. Alternatively, the opposite surfaces of the two side plates of the locking wedge block 32 can be machined into flat surfaces, and the front and rear end faces of the outermost support column 313 can be machined into inclined surfaces that gradually move away from the middle from top to bottom so that the clearance between the locking wedge block 32 and the outermost support column 313 becomes smaller and smaller when the locking wedge block 32 moves downward. In other embodiments, the inner and outer end faces of the cavity can also be machined into inclined surfaces, or the inner and outer end faces of the outermost support column 313 can be machined into inclined surfaces, as long as the distance between a pair of inclined surfaces gradually increases from top to bottom, which will not affect the gradual reduction of the clearance between the locking wedge block 32 and the outermost support column 313 when the locking wedge block 32 moves downward.

[0032] Finally, it should be noted that in the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "vertical", "upper", "lower", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0033] In the description of the present invention, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
