Abstract
The utility model relates to a staircase handrail tip drive protection casing device, including tightener sprocket board, handrail sprocket protection casing, its characterized in that: it is equipped with the tightener sprocket protection casing, and tightener sprocket protection casing and handrail sprocket protection casing one side are close to, and the design of handrail sprocket protection casing has oil to assemble the structure, collects the cusp department that the oil that throws away assembled the lower extreme and drips, and the design of tightener sprocket protection casing connects oily structure, catches the oil that cusp department dripped. The utility model discloses handrail sprocket protection casing design has oil to assemble the structure, collects the cusp department that the oil that throws away assembled the lower extreme and drips, and the design of tightener sprocket protection casing connects oily structure, catches the oil that drips in here to guarantee can not miss oil after the tightener sprocket removes. The problem of current staircase tip handrail drive chain, when refueling when excessive, get rid of inside oil pollution handrail area and the staircase is solved.
Description
Technical field
The utility model relates to escalator technical field, and particularly a kind of escalator handrail end drives protective cover.
Background technology
The general hoisting depth of public transport type staircase is larger, handrail drives and adopts end gyrostat to drive, power is delivered to handrail wheel through a chain, chain needs apply lubrication oil, lubricating oil can throw away by chain high-speed cruising, and the place of chain process needs to add protective cover, to collect the lubricating oil thrown away, preventing pollution, also plays the risk preventing from foreign matter from entering chain blocking.
Because structure needs, chain intermediate demand is turned and is changed path, and chain runs a period of time can be elongated, and need tensioning again, idler sprocket needs shift position, and the closure of protection requires with the requirement on flexibility of chain path contradictory.
Escalator handrail end drives in the market, the unshielded cover of idler sprocket, the number of teeth of idler sprocket ratio of number of teeth head sprocket and handrail sprocket wheel is all few, so centnifugal force is maximum herein, when chain oiling is excessive, the oil overwhelming majority had more throws away herein, pollutes staircase inner, more seriously pollute handrail, the hand of the passenger that makes dirty.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of escalator handrail end to drive protective device, idler sprocket has the structure of protective cover, and solving chain, to get rid of oil pollution staircase inner, pollutes handrail and to make dirty the problem of passenger's hand.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of escalator handrail end drives protective cover, comprise idler sprocket plate, handrail sprocket wheel protective cover, it is characterized in that: it is provided with idler sprocket protective cover, idler sprocket protective cover and handrail sprocket wheel protective cover side close, handrail sprocket wheel protective cover is designed with oily aggregation infrastructure, drip in the cusp place that the oil that collection throws away converges to lower end, idler sprocket protective cover is designed with and connects oily structure, catches the oil dripped in cusp place.
Described idler sprocket protective cover is fixed on idler sprocket plate, can move with idler sprocket, and the moving direction of idler sprocket is designed to vertical with main passive centre of sprocket line, to reduce tensioning amount of movement.
Have wide 0 ~ 5 millimeter of gap between described idler sprocket protective cover and handrail sprocket wheel protective cover, to have prevented oil from spilling, gap length direction is parallel with the moving direction of idler sprocket plate.
Oil converges to the lowest part of idler sprocket cover, and this lowest part arranges an oil guide pipe, is imported by oil in the oil groove bottom staircase.
There is a cusp structure described handrail sprocket wheel protective cover lower end, forms oil and converges cusp.
Two square openings are left in the described other side of idler sprocket protective cover, and the size just company's of allowing chain discrepancy is passed through, and reduces the possibility that oil spills.
The utility model compared with prior art has following beneficial effect: handrail sprocket wheel protective cover is designed with oily aggregation infrastructure, drip in the cusp place that the oil that collection throws away converges to lower end, idler sprocket protective cover is designed with and connects oily structure, catch the oil dripped herein, and ensure that idler sprocket can not miss oil after moving.Solving existing escalator end handrail driving chain bar, when refueling excessive, getting rid of the problem of oil pollution handrail and staircase inside.

Detailed description of the invention
Detailed description of the invention of the present utility model and content is further illustrated below in conjunction with accompanying drawing.
According to Fig. 1 and Fig. 2, the effect of handrail 1 grips for passenger, and falling-resistant, it is wrapped on handrail wheel 2, is driven operation by handrail wheel 2.Handrail sprocket wheel 3 is fixedly connected with one heart with handrail wheel 2, jointly rotates, and drive sprocket 10 passes through handrail chain 9 by transmission of power on handrail sprocket wheel 3.The effect of idler sprocket 5 is by handrail chain 9 tensioning, changes the operating path of chain simultaneously, meets structure space design needs.
Idler sprocket 5 is provided with idler sprocket protective cover 6, and idler sprocket protective cover 6 is fixed on idler sprocket plate 7, can move with idler sprocket 5.Time mobile, fix screw on idler sprocket plate 7 is unclamped, fastening after moving to suitable position.Close between idler sprocket protective cover 6 and handrail sprocket wheel protective cover 4, only stay very little gap between them, between have wide 0 ~ 5 millimeter of gap, spill to have prevented oil, gap length direction is parallel with the moving direction of idler sprocket plate 7, can not change to keep mobile rear gap width size.This moving direction is designed to vertical with the line of centres of handrail sprocket wheel 3 with drive sprocket 10, to reduce tensioning amount of movement.
Handrail sprocket wheel protective cover is designed with oily aggregation infrastructure, and drip in the cusp place that the oil that collection throws away converges to lower end, there is a cusp structure handrail sprocket wheel protective cover 4 lower end, and form oil and converge cusp 11, oil converges to cusp place and drips.The oil that handrail sprocket wheel 9 throws away is blocked in the effect of idler sprocket protective cover 6, and catch the oily oil converging cusp 11 and drip, idler sprocket cover is provided with and connects oily structure, ensure that idler sprocket moves whole process and can receive the oil that handrail sprocket wheel protective cover drips, and ensure that idler sprocket can not miss oil after moving.Oil converges to the lowest part of idler sprocket cover, arranges an oil guide pipe herein, so the work of oil guide pipe 9 will converge to nadir in idler sprocket cover, is imported by oil in the oil groove bottom staircase.Two square openings are left in the other side of idler sprocket protective cover, and the size just company's of allowing chain discrepancy is passed through, and reduces the possibility that oil spills.
