Description

Technical Field

[0001] The present disclosure relates to a step collapse reset device for an escalator. Background Art

[0002] As Figure 1 and Figure 2 shown, the step collapse reset device in the prior art includes a Z-shaped round rod handle ( Figure 2 ). Due to safety regulations, the installation position of the step collapse reset device must be on the crossbeam rotating rod at the first multi-functional board (MPB) near the inclined section of the escalator under the skirt board ( Figure 1 ). Since the original position of the round rod handle for reset is relatively low, when the step collapse switch striker ( Figure 3 ) is deflected by the step and triggers the step collapse safety switch through the safety switch actuating cam (see Figure 3 ), the round rod handle will rotate and deviate from the original position, resulting in an even lower height ( Figure 2 ). Therefore, after troubleshooting, on the premise that only one inner wall board above the skirt board can be removed, the position of the round rod handle is not convenient for personnel to operate, that is, it is not convenient to reset the round rod handle, nor is it convenient to test the function of the step collapse safety switch.

[0003] In addition, if the round rod handle is simply lengthened, due to space limitations, there will be interference problems between the round rod handle and other components of the escalator. Summary of the Invention

[0004] To solve one or more deficiencies in the prior art, according to one aspect of the present disclosure, a step collapse reset device for an escalator is provided, and the step collapse reset device includes a reset handle rod.

[0005] The step collapse reset device further includes a link assembly.

[0006] The reset handle rod is connected to the crossbeam rotating rod of the escalator through the link assembly.

[0007] The rotation of the crossbeam rotating rod is converted into a substantially linear motion of the reset handle rod through the multi-link assembly.

[0008] According to the above aspects of the present disclosure, the link assembly includes a swing arm.

[0009] One end of the swing arm is fixedly connected to the crossbeam rotating rod.

[0010] The rotation of the crossbeam rotating rod can drive the swing of the swing arm.

[0011] According to the above aspects of the present disclosure, the connecting rod assembly further includes a connecting bracket.

[0012] The other end of the swing arm is pivotally connected to one end of the connecting bracket through a hinge component, so that the connecting bracket can rotate relative to the swing arm.

[0013] The other end of the connecting bracket is connected to one end of the reset handle rod through a fastener.

[0014] According to the above aspects of the present disclosure, the connecting bracket is L-shaped, so as to avoid interference with the handrail belt of the escalator.

[0015] According to the above aspects of the present disclosure, the other end of the reset handle rod can extend to a height flush with the upper edge of the skirt board of the escalator.

[0016] According to the above aspects of the present disclosure, the step collapse reset device further includes a guiding bracket.

[0017] The guiding bracket is installed on the skirt board of the escalator through a fastener.

[0018] An elongated guiding bracket opening is provided on the guiding bracket.

[0019] The reset handle rod passes through the guiding bracket opening, so that the guiding bracket opening can limit the swing of the reset handle rod during its linear movement.

[0020] According to the above aspects of the present disclosure, the hinge component includes a screw and a nut.

[0021] According to the above aspects of the present disclosure, the connecting rod assembly is arranged at both ends of the crossbeam rotating rod of the escalator.

[0022] According to the above aspects of the present disclosure, a step collapse switch striker and a safety switch actuating cam are provided on the crossbeam rotating rod.

[0023] After the step collapse switch striker is deflected by the step of the escalator and rotates away from its initial position, it drives the rotation of the crossbeam rotating rod, so that the safety switch actuating cam triggers the step collapse safety switch of the escalator.

[0024] The rotation of the crossbeam rotating rod drives the swing of the swing rod.

[0025] The swing of the swing rod makes the reset handle rod move in a direction approaching the crossbeam rotating rod through the connecting bracket.

[0026] According to the various aspects of the present disclosure, when it is necessary to reset the step collapse safety switch and the step collapse switch lever of the escalator, the other end of the reset handle lever is pulled, so that the reset handle lever moves in a direction away from the crossbeam rotating lever. The movement of the reset handle lever drives the rotation of the crossbeam rotating lever through the connecting bracket and the swing arm. The rotation of the crossbeam rotating lever further drives the step collapse switch lever back to its initial position and causes the safety switch actuating cam to release the trigger of the step collapse safety switch of the escalator.

[0027] According to the technical solution of the present disclosure, the rotation of the step collapse switch lever is changed into a substantially linear up-and-down movement through a connecting rod assembly connected together via a hinge device, optimizing the spatial structure and avoiding the interference problem of simply lengthening the handle.

[0028] In addition, by raising the position of the reset handle lever to the upper edge of the handle flush with the upper edge of the skirt board, it is easy for the operator to observe and operate.

[0029] So far, for a better understanding of the detailed description of the present disclosure herein and for a better recognition of the contribution of the present disclosure to the prior art, the present disclosure has been outlined quite extensively. Of course, the embodiments of the present disclosure will be described below and will form the subject matter of the appended claims.

[0030] Similarly, those skilled in the art will recognize that the concept on which the present disclosure is based can be easily used as a basis for designing other structures, methods, and systems for implementing several purposes of the present disclosure. Therefore, it is important that the appended claims should be considered to include such equivalent structures as long as they do not exceed the substance and scope of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Those skilled in the art will have a better understanding of the present disclosure through the following drawings, and the advantages of the present disclosure can be more clearly reflected. The drawings described here are only for the purpose of illustrating the selected embodiments, not all possible embodiments and are not intended to limit the scope of the present disclosure.

[0032] Figures 1 to 3 Showing a step collapse reset device for an escalator according to the prior art;

[0033] Figures 4 to 5 Showing a step collapse reset device for an escalator according to the present disclosure. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] In the following Figures 1 to 3In the prior art shown, the step collapse reset device includes a Z-shaped round rod handle 1. Due to safety regulations, the installation position of the step collapse reset device must be on the crossbeam rotating rod 4 at the first multi-functional plate 3 (MPB) near the inclined section of the escalator under the skirt board 2. Since the original position of the round rod handle 1 for reset is relatively low, after the step collapse switch lever 5 is deflected by the step and triggers the step collapse safety switch 6 via the safety switch actuating cam 8, the round rod handle 1 will rotate away from its original position, resulting in an even lower height (as shown by the arrow in Figure 2 . Therefore, after troubleshooting, on the premise that only one inner wall board 7 above the skirt board 2 can be removed, the position of the round rod handle 1 is not convenient for personnel to operate, that is, it is not convenient to reset the round rod handle 1, nor is it convenient to test the function of the step collapse safety switch 6.

[0035] The following will specifically describe the specific implementation manners according to the present disclosure in conjunction with Figures 4 to 5 , where the same components as in the prior art have the same reference numerals.

[0036] According to an embodiment of the present disclosure, a step collapse reset device for an escalator is provided, and the step collapse reset device includes a reset handle rod 9.

[0037] The step collapse reset device further includes a link assembly 10.

[0038] The reset handle rod 9 is connected to the crossbeam rotating rod 4 of the escalator through the link assembly 10. The crossbeam rotating rod 4 is rotatably installed on the multi-functional plate 3 of the escalator.

[0039] The rotation of the crossbeam rotating rod 4 is converted into a substantially linear motion of the reset handle rod 9 through the multi-link assembly 10. In Figure 4 and Figure 5 , this linear motion is a vertical motion.

[0040] According to the above embodiments of the present disclosure, the link assembly 10 includes a swing arm 11.

[0041] One end of the swing arm 11 is fixedly connected to the crossbeam rotating rod 4.

[0042] The rotation of the crossbeam rotating rod 4 can drive the swing of the swing arm 11.

[0043] According to the above embodiments of the present disclosure, the link assembly 10 further includes a connection bracket 12.

[0044] The other end of the swing arm 11 is pivotally connected to one end of the connection bracket 12 through a hinge member 13, so that the connection bracket 12 can rotate relative to the swing arm.

[0045] The other end of the connection bracket 12 is connected to one end of the reset handle rod 9 through a fastener.

[0046] According to the above various embodiments of the present disclosure, the connection bracket 12 is L-shaped, so as to avoid interference with the handrail belt 14 of the escalator.

[0047] According to the above various embodiments of the present disclosure, the other end of the reset handle rod 9 can extend to a height flush with the upper edge of the skirt board 2 of the escalator.

[0048] According to the above various embodiments of the present disclosure, the step collapse reset device further includes a guide bracket 15.

[0049] The guide bracket 15 is installed on the skirt board 2 of the escalator through a fastener 16.

[0050] An elongated guide bracket opening 15-1 is provided on the guide bracket 15.

[0051] The reset handle rod 9 passes through the guide bracket opening 15-1, so that the guide bracket opening 15-1 can limit the swing of the reset handle rod 9 during its linear movement.

[0052] According to the above various embodiments of the present disclosure, the hinge member 13 includes a screw and a nut.

[0053] According to the above various embodiments of the present disclosure, the link assembly 10 is arranged at both ends of the cross beam rotating rod 4 of the escalator.

[0054] According to the above various embodiments of the present disclosure, a step collapse switch striker 5 and a safety switch actuating cam 8 are arranged on the cross beam rotating rod 4.

[0055] After the step collapse switch striker 5 is deflected by the step of the escalator and rotates away from its initial position, it drives the rotation of the cross beam rotating rod 4, so that the safety switch actuating cam 8 triggers the step collapse safety switch 6 of the escalator.

[0056] The rotation of the cross beam rotating rod 4 drives the swing of the swing rod 11.

[0057] The swing of the swing rod 11 causes the reset handle rod 9 to move in a direction approaching the cross beam rotating rod 4 through the connection bracket 12, that is, Figure 4 andFigure 5 is moving downward.

[0058] According to the above various embodiments of the present disclosure, when it is necessary to reset the step collapse safety switch 6 of the escalator and the step collapse switch striker 5, the operator only needs to disassemble the inner wall plate 7 to observe the position state of the reset handle rod 9 and very easily access the reset handle rod 9. The operator pulls the other end of the reset handle rod 9, so that the reset handle rod 9 moves in a direction away from the crossbeam rotating rod 4 (i.e., Figure 4 and Figure 5 is moving upward), the movement of the reset handle rod 9 drives the rotation of the crossbeam rotating rod 4 through the connecting bracket 12 and the swing arm 11. The rotation of the crossbeam rotating rod 4 further drives the step collapse switch striker 5 back to its initial position and causes the safety switch actuating cam 8 to release the trigger on the step collapse safety switch 6 of the escalator (at this time, the switch contact of the step collapse safety switch 6 is in the cam recess of the safety switch actuating cam 8 as Figure 3 shown).

[0059] The foregoing disclosure provides illustration and description, but is not intended to be exhaustive or to limit the embodiments to the precise forms disclosed. Modifications and variations can be made in light of the above disclosure, or can be obtained from practice of the embodiments.
