Description

A kind of spindle brake of escalator or moving sidewalk

Technical field

The utility model relates to the technical field of escalator more particularly to the masters of a kind of escalator or moving sidewalk The technical field of shaft brake.

Background technique

Escalator is generally provided with foundation brakes, and foundation brakes are generally arranged on escalator driving system, leads to The operation component of staircase can be made by crossing high speed grade axis such as electric machine main shaft or reduction box input shaft the application braking moment to drive system Such as terraced road system and handrail system stop；In stop staircase, braking moment transmission path is foundation brakes-reduction gearbox-drive Dynamic chain-main shaft-step chains-step.

Currently, escalator mostly connects drive system and main shaft with single row or multiple rows chains, once and chain failure or Failures, the foundation brakes such as driving displacement, which will occur, to fail simultaneously, and reverse, car slipping, overspeed descending etc. inevitably occurs in staircase Dangerous situation.It can be disconnected in foundation brakes failure, drive chain by the additional brake of main representative of spindle brake if be arranged Under the situations such as chain, driving displacement, braking moment directly is applied to main shaft, stop escalator avoids injury accident from occurring or expand Greatly.

But referring to the relevant criterion such as GB 16899 and EN 115 of escalator, when being all only at hoisting depth greater than 6m, Just require escalator and tilting moving sidewalk that additional brake is set；It is not more than the public transport of 6m for hoisting depth Type escalator and tilting moving sidewalk should also install additional brake.So standard compliant not common traffic Type staircase, when smaller hoisting depth are also only to have a foundation brakes.As previously mentioned, such as being added in smaller hoisting depth additional Brake can greatly improve the safety of escalator and tilting moving sidewalk.But current usual structure type Additional brake (spindle brake) all occupy larger computer room space, it is additional be arranged additional brake can make escalator or The civil engineering of moving sidewalk becomes large-sized.Moreover, staircase on, if it is considered that additional brake is arranged again, using routine Infrastructure product will be unable to realize due to space limitations.

In 103241636 B of patent CN, spindle brake is arranged in main shaft obliquely downward, grasps in installation and daily maintenance Work is inconvenient, sight is bad；And actuating strut is in near-horizontal state, center of gravity offset distance is big, forms larger torque to shaft, is smooth It realizes braking and return, needs to be equipped with the spring and spindle brake of larger specification, that is, increase cost and also occupy more Computer room space.

In 106044519 A of patent CN, detent mechanism is arranged in braking wheel side, equally exists installation and daily maintenance Situation inconvenient, sight is bad.And in braking, brake apparatus and its mounting base by main drive wheel braking counter-force and The moment of flexure that brake force is eccentrically formed, stress is more severe, while reinforcing pawl, it is also necessary to additionally add to truss side By force, to increase sectional dimension and bending resistant section coefficient, this is unfavorable for the reduction of truss overall width.

In addition, existing spindle brake 001 is generally underneath type, referring to Figure 1 and shown in Fig. 2, underneath type main shaft system Dynamic device 001 is generally positioned at the lower section at the center of main shaft 0011；Due to 001 its electromagnet of underneath type spindle brake or so width Usually between 150~250mm, therefore maintenance area 002 is largely occupied；And join as shown in figure 3 and figure 4, underneath type master The shaft strength of shaft brake main shaft is analyzed, and when band carries braking, Ft is that the load of staircase passenger is transferred to master by ladder sprocket wheel The power of axle bearing, FN is the power that the brake load that ratchet is subject to is transferred to main shaft bearing, therefore its main shaft bearing bears resultant force F2 It is larger.

Utility model content

The utility model is in view of the above-mentioned problems, provide a kind of escalator of new construction or the main shaft system of moving sidewalk Dynamic device；By the structure improvement to spindle brake and in the position change of escalator or moving sidewalk, so that shaft Positioned at the top of brake actuator center of gravity, so that electromagnet output force request is accordingly reduced, so as to reduce the ruler of electromagnet It is very little；Also, reduces brake actuator and act utilization of the generating mechanism to maintenance area；Therefore improve escalator or The space utilization rate of moving sidewalk, reduces production cost, is easily installed and safeguards.
