The technical scheme is mainly designed from the following aspects:
the guide shoe base in the device is a single sheet metal part, and various functional areas such as an installation socket, a clamping groove, a connecting hole and the like of related matched parts are obtained by adopting an opening notch through an integrated structure formed by plates, so that the guide shoe base has enough structural strength and has certain buffering capacity in an overload state; the integrated framework is also embodied on the parts such as the groove frame and the lining seat of the damping mechanism in the scheme, after the limiting body of each assembly part is obtained, the integrated framework also has reasonable elastic quantity, so that the aims of integrally stressing and integrally damping the product are fulfilled, the accommodating space of the shoe liner is not only provided for extrusion, protection and limitation in movement, but also the shoe liner is more importantly self-lubricated once abnormal phenomena such as deflection and vibration occur in the working process, and the friction force of the elevator guide rail is reduced.
Secondly, damper in this device is an intermediate, both provides the U-shaped mounting groove of installation boots lining for overhaul and change boots lining and become more light simple, designed a multidimension degree shock-absorbing ball again, the shock attenuation of structure such as relative conventional square is different, a plurality of spheroid structure shock-absorbing ball just arranges inside whole guide shoe, no matter the ordinary vibration that the car received when getting on or off the bus, the unusual vibration that appears under the unusual condition, can both follow three-dimensional, multi-angle direction effectively and shock attenuation, especially meet burst type wave vibration. Specifically speaking, the damping ball of this scheme is fixed with the support frame through the chord on the spheroid, adopts polyurethane material one shot forming, and the damping ball withstands the lining seat simultaneously and withholds and lead the boots base and form trinity shock attenuation, when the boots lining atress, at first alleviates the impact force and reaches the shock attenuation through damper mechanism cell frame and lead the two-axis (X/Z) direction deflection between the boots base two parts according to the atress size, and when boots lining atress is too big, can promote damper mechanism cell frame and lead the laminating (Y to) of the buffering clearance that bottom surface kept in U-shaped mounting groove of boots base U type draw-in groove and lead boots base two parts outside bottom surface and reach the shock attenuation effect once more.
The boot liner body in the scheme is composed of an ultrahigh molecular weight polyethylene liner body and grease stored in the liner body in a mixing mode, a certain amount of grease can be contained in the liner body, and grease can be automatically oozed out from the inner side of the boot liner body when the boot liner body is in extrusion friction with the edge of the guide rail, so that the purpose of self lubrication without oiling is achieved. The ultra-high molecular weight polyethylene (UHMW-PE) is a thermoplastic engineering plastic with a linear structure and excellent comprehensive performance, the density is less than that of water, the thermal deformation temperature (0.46 MPa) is 85 ℃, the melting point is 130-136 ℃, and the requirements of normal operation of elevator guide shoes can be met. The bootie may be molded by extrusion, blow molding, injection molding, and other special methods. Further, according to the over-pressure extrusion principle of the device, the contact surface of the shoe liner and the elevator guide rail is a corrugated surface, so that an ideal lubrication effect can be obtained in a maintenance service period of the elevator according to the extrusion deformation under the normal vibration state of the elevator.
In addition, the dust cleaning brush at the upper end of the guide shoe cleans the guide rail in all directions through the three-block brush head, the middle brush right opposite to the top of the guide rail is arranged, the side brushes with two-side cleaning capability are arranged, no matter the elevator stops for a long time, the environment is poor, foreign matters can be prevented from entering the shoe lining, and after the elevator operates normally, the dust cleaning brush can clean the foreign matters on the guide rail up and down.
In the later maintenance period, when the shoe liner is required to be replaced after being worn seriously, the shoe liner can be directly taken out from the front surface of the guide shoe, even after the shock absorption mechanism, the lining seat and other parts are damaged, the shoe liner can also be directly replaced, and the aim of high interchangeability is fulfilled.
The beneficial effects of the invention are as follows: not only saves the oiling devices such as the oil cup on the guide shoe, simplifies the structure, solves the problems of serious greasy dirt and large occupied top layer/pit space, but also eliminates the range limitation of the guide shoe directivity selection; not only the whole whip achieves the whole stress and the integral shock absorption, but also the effective shock absorption is obtained from three-dimensional, multidimensional and multi-angle, and especially the abnormal shock phenomena such as burst or wave can be dealt with; reasonable and compact structure and convenient replacement and maintenance.
