[0038] First, as Figure 1 as well as Figure 2 As shown, the present application provides a fault identification device 10, which can be arranged in cooperation with different step structures 20 to implement fault detection of the step structure 20. The fault identification device 10 includes an installation module 100 and at least one detection element 200, wherein:

[0039] Continue to refer Figure 3 The mounting module 100 includes a transition plate 110, a plurality of pressure codes 120, and a fastening assembly 130. The transition plate 110 is arranged at a triangular support position of the step structure 20. The pressure code 120 abuts against a stacking change position of the step structure 20 and the transition plate 110. The fastening assembly 130 penetrates the pressure code 120 and the transition plate 110, and the fastening assembly 130 connects the transition plate 110 to the step structure 20. At this time, the pressure code 120 is fixed at a stacking change position of the step structure 20 and the transition plate 110, so that the step structure 20 is crimped between the pressure code 120 and the transition plate 110.

[0040] The detection element 200 is fixed on the transition plate 110, and the detection element 200 is used to detect the operating state of the step structure 20. In one example, the number of the detection elements 200 can be one, two, three, or more than three; the detection element 200 can be any one of a wireless vibration sensor, a wireless gyroscope, and a photoelectric sensor, and the detection element 200 can also be other structural forms that can realize the operating state detection of the step structure 20.

[0041] In the above-mentioned fault identification device 10, no matter what the structural form of the detection element 200 is, it can be fixed on the transition plate 110. No matter what the structural form of the step structure 20 is, it can be set on the step structure 20 through a transition plate 110 of a structural size, and then the pressure code 120 is abutted on the stacking change position with the transition plate 110 that is present in any step structure 20, and the transition plate 110 and the step structure 20 are connected as a whole by a fastening assembly 130 that passes through the pressure code 120 and the transition plate 110. At this time, the step structure 20 is abutted and fixed between the pressure code 120 and the transition plate 110 to adapt to the installation and fixation of different detection elements 200 on various step structures 20, so that the fault identification device 10 has better versatility. Moreover, during the process of installing the above-mentioned fault identification device 10 on the step structure 20, there is no need to make any improvements to the step structure 20, so that the step structure 20 has better stability, avoiding quality and safety risks such as deformation of the step structure 20, collapse of the step structure 20, and people falling, thereby improving safety.

[0042] In order to facilitate the setting of the compression code 120, in a preferred embodiment, as Figure 3 as well as Figure 4 As shown, the transition plate 110 covers at least part of the tripod rib plate 21 of the step structure 20, one end of the pressure code 120 is arranged on the transition plate 110, and the other end of the pressure code 120 is arranged in the tripod rib plate 21. Since the tripod rib plate 21 of the step structure 20 is a groove-shaped structure with one end open, one end of the pressure code 120 is arranged in the groove opening of the tripod rib plate 21, on the one hand, it is convenient to locate the installation position of the pressure code 120, and to facilitate the setting of the pressure code 120 at the stacking change position of the step structure 20 and the transition plate 110, and on the other hand, it can also avoid the movement of the pressure code 120 at the stacking change position of the step structure 20 and the transition plate 110, so that after the pressure code 120 fixes the step structure 20 and the transition plate 110, the fixed connection stability between the three is better, thereby improving the installation stability of the above-mentioned fault identification device 10 on the step structure 20.

[0043] The compression code 120 has various structural forms, specifically, Figure 3 as well as Figure 4As shown, the pressing code 120 has a first abutting section 121 and a second abutting section 122 . The first abutting section 121 abuts on the transition plate 110 , and the second abutting section 122 abuts inside the tripod rib plate 21 , and the length of the second abutting section 122 is less than that of the first abutting section 121 . Since the overall thickness of the end portion of the second abutting section 122 of the pressing code 120 after assembly is the thickness of the pressing code 120 + the length of the second abutting section 122 + the thickness of the tripod rib 21 + the thickness of the transition plate 110, the overall thickness of the end portion of the first abutting section 121 of the pressing code 120 is the thickness of the pressing code 120 + the length of the first abutting section 121 + the thickness of the transition plate 110, by limiting the length of the second abutting section 122 to be smaller than the length of the first abutting section 121, so that the length of the second abutting section 122 + the thickness of the tripod rib 21 can match the length of the first abutting section 121, the two ends of the pressing code 120 can abut in a balanced manner, ensuring the stable setting of the pressing code 120.

[0044] In order to improve the applicability of the above-mentioned fault identification device 10, more specifically, the length difference between the first abutment section 121 and the second abutment section 122 can be 3mm-10mm, so that the pressure code 120 can be applicable to various tripod ribs 21 with a thickness within the range of 3mm-10mm, so that the range of ladder structures 20 that the fault identification device 10 can be applied to is wider. In one example, the length difference between the first abutment section 121 and the second abutment section 122 can be any one of 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, and 10mm, and the length difference between the first abutment section 121 and the second abutment section 122 can also be other values ​​within the range of 3mm-10mm. In another example, the pressure code 120 can be a metal bending part, and the pressure code 120 can be prepared on-site according to different ladder structures 20 during installation, further improving the applicability of the fault identification device 10. In another example, the pressure code 120 can be a casting or an injection molded part. A series of pressure codes 120 can be pre-designed, and the length difference between the first abutment section 121 and the second abutment section 122 is in the range of 3mm-10mm. A suitable pressure code 120 is selected during installation, and when there is a slight difference in size, the balance at both ends of the pressure code 120 can be adjusted by placing gaskets or the like.

[0045] In order to facilitate the relative arrangement of the transition plate 110 and the tripod rib plate 21, specifically, as Figure 3 as well as Figure 4As shown, a limiting step 111 is formed around the transition plate 110, and the shape of the limiting step 111 is adapted to the tripod rib plate 21, which can facilitate the stacking positioning of the transition plate 110 on the tripod rib plate 21. The tripod rib plate 21 abuts against the side wall of the limiting step 111. On the one hand, the tripod rib plate can be positioned through the side wall of the limiting step 111, which facilitates the relative positioning of the transition plate 110 and the tripod rib plate 21. On the other hand, it can also prevent the tripod rib plate 21 and the transition plate 110 from moving relative to each other after assembly. The fixed connection stability of the tripod rib plate 21 and the transition plate 110 is good, which improves the installation stability of the above-mentioned fault identification device 10 on the step structure 20. In one example, when designing the length of the first abutting section 121 and the second abutting section 122 of the pressure code 120, the depth of the limiting step 111 also needs to be considered. The length difference between the first abutting section 121 and the second abutting section 122 = the thickness of the tripod rib plate 21 - the depth of the limiting step 111.

[0046] In order to further improve the installation stability of the fault identification device 10 on the step structure 20, in a preferred embodiment, Figure 2 As shown, the number of groups of the pressing code 120 and the fastening assembly 130 can be at least three, and the multiple groups of the pressing code 120 and the fastening assembly 130 are evenly arranged on the transition plate 110, so that the connection force between the transition plate 110 and the step structure 20 is more even, and the connection reliability between the transition plate 110 and the step structure 20 is improved. In an example, the number of groups of the pressing code 120 and the fastening assembly 130 can be three, four, five or more than five, and the number of groups of the pressing code 120 and the fastening assembly 130 can be specifically selected according to the actual structure of the step structure 20.

[0047] The fastening assembly 130 has various structural forms. In a preferred embodiment, Figure 3 as well as Figure 4As shown, the fastening assembly 130 includes a fastening bolt 131 and a fastening nut 132. The pressure code 120 is provided with a first through hole 123, and the first through hole 123 penetrates the middle area of ​​the pressure code 120 along the thickness of the pressure code 120. The transition plate 110 is provided with a second through hole 112. The screw of the fastening bolt 131 penetrates the first through hole 123 and the second through hole 112, and the screw of the fastening bolt 131 is locked with the fastening nut 132 located on the side of the transition plate 110 away from the pressure code 120, so that the transition plate 110, the ladder structure 20 and the pressure code 120 can be more conveniently fixedly connected. In one example, the locking position of the fastening nut 132 and the screw can be adjusted to adapt to different pressure codes 120. Of course, the structural form of the fastening assembly 130 is not limited to the above-mentioned fastening bolts 131 and fastening nuts 132, and can also be other structural forms that can meet the requirements, such as screws. In this case, the second through hole 112 can be correspondingly set as a threaded hole.

[0048] In order to facilitate the installation of the detection element 200, in a preferred embodiment, Figure 2 as well as Figure 4 As shown, the detection element 200 is installed on the transition plate 110 through the fixing assembly 300, and the fixing assembly 300 includes a bracket 310, a first fastener 320 and a second fastener 330, wherein: the bracket 310 is a U-shaped structure with one end open, and the internal space of the bracket 310 is used to accommodate the detection element 200, and the bracket 310 is fixed to the transition plate 110 through the first fastener 320. In one example, in order to facilitate installation, the bracket 310 can be fixed to the transition plate 110 first, at this time, the opening of the bracket 310 is away from the transition plate 110, and then the detection element 200 is installed. In another example, the bracket 310 is not limited to the above-mentioned U-shaped structure, and can also be a closed frame-shaped structure, or other structural forms that can meet the requirements. The detection element 200 is arranged in the bracket 310, and the detection element 200 is fixed in the bracket 310 through the second fastener 330. In one example, the first fastener 320 can be a threaded connector such as a screw or a bolt, and the structure of the second fastener 330 can be the same as that of the first fastener 320, or it can be a threaded connector different from the first fastener 320. For example, the second fastener 330 is a mounting bolt 331 + a mounting nut 332, and mounting holes are respectively provided on the bracket 310 and the transition plate 110. The screw rod of the mounting bolt 331 passes through the mounting hole and is locked with the mounting nut 332 to achieve a fixed connection between the bracket 310 and the transition plate 110.

[0049] In order to prevent the detection element 200 from falling off, specifically, as Figure 4As shown, the fixing assembly 300 also includes a bolt group 340, the bracket 310 has a first connecting section 311 and a second connecting section 312, the first connecting section 311 and the second connecting section 312 are arranged opposite to each other in the up-down direction, the detection element 200 is fixed to the first connecting section 311, the bolt group 340 is fixed to the second connecting section 312, and there is a gap of 0.5mm-1.5mm between the bolt group 340 and the detection element 200, so that when the connection between the detection element 200 and the first connecting section 311 is loosened, the detection element 200 can directly fall onto the bolt group 340 and can be supported by the bolt group 340 to prevent the detection element 200 from falling off due to the connection failure of the second fastener 330. Moreover, the vibration detected by the detection element 200 changes before and after the detection element 200 falls off, and the monitoring personnel can determine that the detection element 200 is at risk of falling off according to this situation and manually tighten the second fastener 330 or adjust the position of the bolt group 340. In one example, the gap between the bolt group 340 and the detection element 200 may be 0.5 mm, 0.7 mm, 0.9 mm, 1.0 mm, 1.2 mm, 1.4 mm, or 1.5 mm. Of course, the gap between the bolt group 340 and the detection element 200 may also be other values ​​within the range of 0.5 mm to 1.5 mm.

[0050] Second, as Figure 1 as well as Figure 2 As shown, the present application also provides an escalator 01, which includes a step structure 20 and a fault identification device 10 as described in any of the above technical solutions, wherein a transition plate 110 of the fault identification device 10 is fixedly connected to the step structure 20 as a whole.

[0051] In the above-mentioned escalator 01, after the detection element 200 is fixed on the transition plate 110, the transition plate 110 is set at the triangular support position of the step structure 20, the pressure code 120 abuts against the stacking change position of the step structure 20 and the transition plate 110, and the transition plate 110 and the step structure 20 are connected as a whole by the fastening assembly 130 that passes through the pressure code 120 and the transition plate 110, so as to realize that the detection element 200 is fixed on the step structure 20 through the installation module 100. For various detection elements 200 and various step structures 20, only one transition plate 110 of a structural size is required to be set on the step structure 20, and the setting position of the pressure code 120 is at a stacking change position with the transition plate 110 regardless of the step structure 20, and the step structure 20 is abutted and fixed between the pressure code 120 and the transition plate 110 by the fastening assembly 130, which can be applicable to the installation and fixation of various detection elements 200 on different step structures 20, so that the fault identification device 10 has better versatility. In addition, there is no need to improve the step structure 20. In the fixed connection, the fastening assembly 130 penetrates the pressure code 120 and the transition plate 110, so that the stability of the step structure 20 is better, avoiding the quality and safety risks such as deformation of the step structure 20, collapse of the step structure 20, and personnel falling, thereby improving safety.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
