Abstract
The invention relates to a headstock positioning sleeve device. The headstock positioning sleeve device comprises a hand strap rotating wheel and transitional angled parts which are symmetrically distributed on the two sides of the hand strap rotating wheel, wherein circular-arc plates are arranged on the outer sides of the transitional angled parts, a positioning sleeve is fixedly connected between the circular-arc plates by using a bolt assembly, and the positioning sleeve is of a cylindrical structure. In order to firmly connect the positioning sleeve, the bolt assembly comprises a bolt, spring washers and flat gaskets. The headstock positioning sleeve device provided by the invention has the beneficial effects that after the device is arranged between the circular-arc plates, the circular-arc plates can be prevented from being bent and deformed, the collision of the hand strap rotating wheel is prevented from occurring during movement, the potential safety hazard of an escalator is reduced and personal safety accidents are prevented from being caused.
Description
technical field:
The present invention relates to the abutment sleeve that the oblique handrail tap of public traffic type uses, belong to staircase technology.
background technology:
In staircase technical field; handrail is the armrest member of standing for passenger; be in operation and play conclusive effect; handrail is driven by handrail gyrostat; need certain running space during the motion of handrail gyrostat, but in actual application, often can find the arc plate meeting flexural deformation being arranged at gyrostat both sides, thus handrail gyrostat can be caused to collide in motion process; potential safety hazard can be produced to staircase, probably cause personal safety accident.
summary of the invention:
Technical matters to be solved by this invention is: provide a kind of leading abutment sleeve device, be arranged between arc plate, prevent arc plate flexural deformation, decrease the hidden danger of staircase safe operation by this device.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of leading abutment sleeve device, includes handrail gyrostat, is symmetrically distributed in the transition angle-shaped piece of described handrail gyrostat both sides.
In order to increase the running space of handrail gyrostat, further, the arranged outside of described transition angle-shaped piece has arc plate.
In order to prevent arc plate to be out of shape, having influence on the safe in operation of whole staircase, further, between described arc plate, being fixedly connected with abutment sleeve with bolt assembly.
In order to facilitate connecting positioning sleeve cylinder, more further, described abutment sleeve is cylindrical-shaped structure.
In order to can firmly connecting positioning sleeve cylinder, further, the center of described abutment sleeve arranges tapped through hole, and described bolt assembly includes bolt, spring washer, plain cushion.
Compared with prior art, usefulness of the present invention is: provide a kind of leading abutment sleeve device, this device is arranged between arc plate, prevent arc plate flexural deformation, thus prevent handrail gyrostat from can collide in motion process, reduce staircase and produce hidden danger, prevent from causing personal safety accident.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is assembly drawing of the present invention.
In figure: 1, handrail gyrostat; 2, transition angle-shaped piece; 3, arc plate; 4, bolt assembly; 5, abutment sleeve; 4-1, bolt; 4-2, spring washer; 4-3, plain cushion.
detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments: a kind of leading abutment sleeve device according to Fig. 1, include handrail gyrostat 1, be symmetrically distributed in the transition angle-shaped piece 2 of described handrail gyrostat 1 both sides, the arranged outside of described transition angle-shaped piece 2 has arc plate 3, abutment sleeve 5 is fixedly connected with bolt assembly 4 between described arc plate 3, described abutment sleeve 5 is in cylindrical-shaped structure, the center of described abutment sleeve 5 arranges tapped through hole 6, described bolt assembly 4 includes bolt 4-1, spring washer 4-2, plain cushion 4-3.
During use, transition angle-shaped piece 2 is positioned over the both sides of handrail gyrostat 1, arc plate 3 is fixedly connected on the outside of transition angle-shaped piece 2, again abutment sleeve 5 is positioned between described arc plate 3, through spring washer 4-2 and plain cushion 4-3, abutment sleeve 5 is fixedly connected on arc plate 3 with bolt 4-1, and then has just propped up arc plate 3, prevent arc plate 3 to be out of shape, thus increase the motion space of handrail gyrostat 1, and then improve the safety performance of whole staircase.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
