Abstract
The invention discloses an overspeed brake with buffer for a window cleaner, which comprises a reel, a reel axis and a ratchet wheel, wherein the reel and the ratchet wheel are arranged on an installation plate through the reel axis, the reel axis is further provided with a colliding joint, two ends of the reel axis are provided with side plates, one side of a side plate is hinged with a pallet, the pallet is matched with the ratchet wheel, one end of the pallet, which is not matched with the ratchet wheel, is provided with a roller through a spindle, and the pallet is provided with a pallet reset device; and the front end of the side plate is provided with a buffer spring, the reel axis is provided with a gear assembly, and the gear assembly is connected with two manual nuts. The overspeed brake has favorable performance, and the overspeed brake can buffer the impact received by a braking device, a transmission shaft and other relative connecting pieces through the buffering of the buffer spring in the process of braking the overspeed, and protect the brake, so that the reliability of the brake is greatly enhanced, and the use of the brake becomes safer.
Description
Technical field
The present invention relates to a kind of overrun brake, particularly relate to a kind of window cleaning equipment band buffering overrun brake.
Background technology
Window cleaning machine hanging basket can install overrun brake usually to carry out safety guard-safeguard; existing overrun brake is mainly the drg of bag lock form drg and ratchet form; the drg in-service time of bag lock form is usually longer; be opened into braking at it to have certain effect the time; safety misadventure may occur in this time, also easily there is the not dead situation of card in bag lock in addition.
Automatic load sustaining brake coordinates directly locked with ratchet by ratchet, make the direct stop motion of weight, this situation can make brake equipment, transmission shaft and each related fittings be subject to very large impulsive force instantaneously, be easy to the damage causing part, and cause that brake equipment is malfunctioning causes safety misadventure.
Summary of the invention
The technical matters that the present invention solves is: provide a kind of overrun brake with shock absorber at first it to be carried out to the buffering of certain distance in braking, reduce weight speed gradually, proterctive equipment part.
For reaching this object, the present invention by the following technical solutions:
A kind of window cleaning equipment band buffering overrun brake, comprise reel, drum shaft and ratchet, described reel and ratchet are installed on a mounting board by drum shaft, described drum shaft is also provided with and meets and discusses, described drum shaft two ends are provided with side plate, the side plate of described side is hinged with ratchet, described ratchet coordinates with ratchet, one end that described ratchet does not match with ratchet is provided with roller by rotating shaft, described ratchet is provided with ratchet pawl reset device, described side plate front end is provided with recoil spring, described drum shaft is provided with gear assembly, described gear assembly connects two manual nuts.
Further, described ratchet pawl reset device is adjustable counter balance.
Further, described in meet and discuss to be arranged on and meet and discuss on reaction plate, described in reaction plate of meeting and discussing be fixed in drum shaft.
Further, meet and discuss described in is meet and discuss reaction plate circumference uniform distribution in three edges.
Further, described recoil spring is set on spring guide, and described spring guide is on a mounting board hinged by guide rod seat.
Beneficial effect of the present invention is: deceleration and stopping performance is good; the impulsive force that can be received by buffering alleviation brake equipment, transmission shaft and each related fittings of recoil spring in the process of braking exceeding the speed limit; protection drg, makes the reliability of drg greatly improve, uses safer.

Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in figures 1-4, in the present embodiment, a kind of window cleaning equipment band buffering overrun brake of the present invention, it comprises the reel 1 for retractable cable, described reel 1 is arranged on adapter plate 4 by drum shaft 2 and bearing, described drum shaft 2 is also provided with ratchet 3, to meet and discuss reaction plate 13 and two blocks of side plates 6, wherein one block of side plate 6 is hinged with ratchet 7, described reaction plate 13 of meeting and discussing is circular, it is circumferentially furnished with three uniformly and meets and discusses 5, described ratchet 7 other end is provided with roller 9 by rotating shaft 8, described rotating shaft 8 is arranged in waist-shaped hole 10 and also can moves along waist-shaped hole 10, lower end is provided with spacing feeler lever, described spacing feeler lever is for triggering limit switch, be provided with adjustable counter balance 12 below described ratchet 7 and snap in ratchet 3 for limiting ratchet 7.
Described side plate 6 front end is provided with guide rod sliding sleeve, spring guide 14 is provided with in described guide rod sliding sleeve, described spring guide 14 is arranged with recoil spring 11, described guide rod sliding sleeve and side plate 6 hinged, described spring guide 14 other end is hinged on guide rod seat 15 by guide rod anchor shaft, and described guide rod seat 15 is fixing on a mounting board.
In the process of unwrapping wire, reel 1 can constantly rotate, and when weight declines with normal speed time, reel 1 velocity of rotation is comparatively slow, now ratchet 7 under the effect of adjustable counter balance 12 gravity away from ratchet 3; When weight declines hypervelocity time, reel 1 velocity of rotation is accelerated, now meet and discuss and reaction plate 13 meets and discusses 5 constantly with speed impacts roller 9 faster, due to momentum comparatively big roller 9 move along waist-shaped hole, cause ratchet 7 other end upward movement to snap in ratchet 3, ratchet 3 stops operating.Now because inertia ratchet 3 still has the trend of rotation, impel ratchet 3 to extrude ratchet 7, ratchet 7 drives side plate 6 to rotate along drum shaft 2, and side plate is shunk by guide rod loop bar extruding recoil spring 11 and realizes buffering.
When unclamping ratchet 3, transmission gear 17 is relied on to make ratchet 3 reversion unclamp ratchet 7 by replacing rotation two manual nut 16,7, ratchet can take out, alternately rotary manual nut 16 can ensure have a manual nut 16 to be in control at any time, gear assembly reversion when preventing from unclamping another manual nut 16.
It is to be understood that; above-mentioned detailed description of the invention is only preferred embodiment of the present invention and institute's application technology principle; in technical scope disclosed in this invention, the change that any those skilled in the art of being familiar with easily expect or replacement, all should be encompassed in protection scope of the present invention.
