Problems solved by technology

However, no matter adding a water suction wheel or adding a water paddle, it will increase the maintenance burden of the equipment.
In addition, the paddles only push the water inside the handrail from the center of the handrail to the sides, not to remove the water, and cannot solve the problem of aging of the handrail caused by water seepage

no. 1 Embodiment

[0024] figure 1 It is a schematic structural diagram briefly showing the passenger conveyor 100 related to the embodiment of the present invention. figure 1 The passenger conveying device 100 shown is an escalator, but the passenger conveying device to which the present invention is applicable may also be a moving walk. Passenger conveyor 100 includes trusses 102, steps 104, curbs 106, drive machines 110, drive sprockets 114, and handrail arrangements.

[0025] The truss 102 is installed on a building and is a structure that supports other parts of the passenger conveyance facility. The steps 104 are arranged in the truss 102, and a plurality of steps 104 are connected in a ring by a step chain 116, and the passengers are conveyed through circular movement. The driving machine 110 is composed of an electric motor, a speed reducer, and the like. The driving machine 110 drives the driving sprocket 114 through the driving chain 112 , the driving sprocket 114 drives the step ch...

no. 2 Embodiment

[0043] Figure 8 It is a schematic structural view schematically showing a handrail belt and a handrail rail according to a second embodiment of the present invention. Figure 9 is briefly Figure 8 A schematic diagram of the overall structure of the handrail and the handrail rail shown. This embodiment is a modified example of the first embodiment. The handrail device of this embodiment also has a drainage structure similar to that of the first embodiment. Hereinafter, only the technical features of this embodiment that are different from those of the first embodiment will be described.

[0044] Such as Figure 8 As shown, the handrail 808 of this embodiment is provided with a drainage hole 830, and is equipped with the same drainage hole pin 400 and anti-drop component 410 as the first embodiment. The drain hole 830 runs through the handrail 808 and includes three sections of different shapes. These sections are cylindrical bore 830a, conical bore 830b, and cylindrical...

no. 3 Embodiment

[0047] Figure 11 It is an assembly schematic diagram which briefly shows that the drain hole pin 1140 of the third embodiment is assembled to the drain hole 1130 . This embodiment is a modified example of the first embodiment. The handrail device of this embodiment also has a drainage structure similar to that of the first embodiment. Hereinafter, only the technical features of this embodiment that are different from those of the first embodiment will be described.

[0048] Such as Figure 11 As shown, the handrail 1108 of this embodiment is provided with a drainage hole 1130, and is equipped with a drainage hole pin 1140 and an anti-drop component 410 exactly the same as that of the first embodiment. The drainage hole 1130 runs through the handrail 1108 and includes 4 sections of different shapes. These segments are cylindrical bore 1130a, conical bore 1130b, cylindrical bore 1130c, and cylindrical bore 1130d, respectively. These sections of the drain hole 1130 correspo...

Abstract

The invention relates to passenger transporting equipment (100) and a handrail device thereof. The handrail device comprises a hand strap (208) with a water drainage hole (300), and a water drainage hole pin (400), wherein the water drainage hole penetrates through the hand strap and comprises a region including a conical hole (300b); in the ascending stage of the hand strap, the conical hole is an inverted conical hole of which the diameter of an opening in the upper part is larger and the diameter of an opening in the lower part is smaller; the water drainage hole pin comprises a region including a frustum (400b); the frustum is provided with a conical surface corresponding to the conical hole; when the water drainage hole is in the ascending stage of the hand strap, the frustum enters the conical hole to close the water drainage hole; when the water drainage hole is in the descending stage of the hand strap, the frustum leaves the conical hole by a preset distance to form a clearance for discharging liquid. Therefore, the handrail device can drain liquid permeating into the inner side of the hand strap in time, and aging of the hand strap can be prevented; furthermore, the water drainage structure is simple, and maintenance is facilitated.

Description

technical field [0001] The invention relates to passenger conveying equipment and a handrail device thereof. Background technique [0002] Passenger conveying equipment such as escalators and moving walks generally have moving handrails. The moving part of the handrail device is the handrail belt, which generally has a C-shaped cross-section, and the opening of the C-shaped opening is placed on the handrail guide rail and slides along the handrail guide rail. The handrail is circularly connected and moves, and its operation process can be divided into an upward phase and a downward phase. The so-called ascending stage refers to the stage for passengers to support, and the so-called descending stage refers to the stage where the handrail returns. When the handrail is in the ascending stage, the opening of the C letter is facing downward, and when the handrail is in the descending stage, the opening of the C letter is facing upward. The driving wheel is arranged on the inne...
